How can I access “Visual Studio Conversion Wizard” for a WebSite?

2012-03-27T09:09:00.002-06:00

I'm using this article to convert my ASP.NET 2.0 web application to an ASP.NET 4.0 application.
However, the article states that I will be prompted to change to .NET 4.0 when I open up my project/website.
As I've previously declined this dialog I'm not longer being prompted.
I've read this question which states I should click on the Properties tab of my solution, but I only have "Properties Window". Perhaps this is just for Projects/
How can I get the conversion wizard to reappear for my WebSite was the question of the moment... I looked everywhere and could not find a solution...

Update:

I haven't been able to get the Conversion Wizard to reappear, but I have been able to convert to .NET 4.0 by:
Right Clicking on my website
Selecting Property Pages
Then go to Build tab
Change Target Framework
This made all the changes to my web.config automatically just like the conversion wizard would.

Site seems to be running in 4.0 ...testing time I say.

I hear that breaking things is the best way to learn new concepts.

Anyhu, while working with SQLServerCompact, I had this issue
Could not load file or assembly 'System.Data.SqlServerCe.Entity, Version=4.0.0.1, Culture=neutral, PublicKeyToken=89845dcd8080cc91' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference.

I wasnt sure what the issue exactly was and then realized that there was a dependency line in my web.config refereing to this assembly

I removed this dependent assembly and my scaffolded control works likea charm now..

MVC 3 Scaffolding

2012-03-16T12:15:00.001-06:00

SO I was playing with package manager in MVC and tried to install MVCScaffolding ...

http://blog.stevensanderson.com/2011/01/13/scaffold-your-aspnet-mvc-3-project-with-the-mvcscaffolding-package/

Has all the details I was following to the dot...

kept on getting this error and was very baffled

PM> Scaffold Controller Team
The term ‘Scaffold’ is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, ver
ify that the path is correct and try again.
At line:1 char:9
+ Scaffold <<<< Controller Team
+ CategoryInfo : ObjectNotFound: (Scaffold:String) [], CommandNotFoundException
+ FullyQualifiedErrorId : CommandNotFoundException

I managed to solve the problem by uninstalling and reinstalling the MvcScaffolding. That didn’t work at first, but when I uninstalled it using the -RemoveDependencies switch, and then reinstalled it again, everything worked fine again.
So you can try this:
Uninstall-Package MvcScaffolding -RemoveDependencies
Install-Package MvcScaffolding

I was also told that updating the package resolves the issue though am not sure about that...

Here is the code for the bravehearted to try:

1. Enter into your package manager console “Update-Package MvcScaffolding”
2. Then restart Visual Studio

MVC woes

2012-03-13T08:28:00.000-06:00

So, I am diligently working with MVC 3... and ran into a very simple but convoluted problem. I was working with EF "code first" model and modified my model to add some validations...

Guess what ? It stopped running after that. Kept repeating the following message:

The model backing the 'MyDBContext' context has changed since the database was created. Either manually delete/update the database, or call Database.SetInitializer with an IDatabaseInitializer instance. For example, the DropCreateDatabaseIfModelChanges strategy will automatically delete and recreate the database, and optionally seed it with new data.

Solution:
We need to update the table in Sql Server to have the additional column you added to your entitiy class.

Database.SetInitializer(new DropCreateDatabaseIfModelChanges());

This line is used for in order to allow to edit database by making changes to Model objects.Add this line in Global.asax at Application_Start() method.

Inside the Application_Start method, define the Database initializer with one among the two options.

DropCreateDatabaseAlways: This will drop and recreate the database in every application start.

DropCreateDatabaseIfModelChanges: This will drop and create the database only if the underlined model changes.

Sample code:

protected void Application_Start()
{
Database.SetInitializer(newDropCreateDatabaseIfModelChanges());

AreaRegistration.RegisterAllAreas();

RegisterGlobalFilters(GlobalFilters.Filters);
RegisterRoutes(RouteTable.Routes);
}

Now it is working perfectly.

Note: DropCreateDatabaseIfModelChanges should only be use early on in development, never on a production machine. If you pushed to a production machine and made schema changes, you'd loose all your data.

Naan

2011-10-24T13:20:00.001-06:00

Ingredients:

2 cups of All Purpose flour (Plain flour or maida)
1 teaspoon active dry yeast
1 teaspoon salt
1 teaspoon sugar
Pinch of baking soda
2 tablespoons of oil
2 1/2 tablespoons yogurt (curd or dahi)
3/4 cup lukewarm water

Also needed:

1 teaspoon of clear butter or ghee to butter the Naan
1/4 cup All Purpose flour for rolling

Method:

Dissolve active dry yeast in lukewarm water and let it sit for 10 minutes or until the mixture becomes frothy.
Add sugar, salt and baking soda to the flour and mix well.
Add the oil and yogurt mix, this will become crumbly dough.
Add the water/yeast mixture and make into soft dough.Note: after dough rise will become little softer.
Knead until the dough is smooth. Cover the dough and keep in a warm place for 3-4 hours. The dough should almost be double in volume.
Heat the oven to 500 degrees with pizza stone for at least thirty minutes so stone is hot. Using a pizza stone will help to give naan close to same kind of heat as clay tandoor.
Next turn the oven to high broil.
Knead the dough for about two to three minutes and divide the dough into six equal parts.
Take each piece of dough, one at a time, and roll into 8-inch oval shape. Dust lightly with dry flour to help with the rolling.
Before putting the Naan in oven, lightly wet your hands and take the rolled Naan, and flipp them between your palms and place onto your baking/pizza stone into the oven.
You can place about 2 Naan on the baking/pizza stone at a time. The Naan will take about 2 to 3 minutes to cook, depending upon your oven. After the Naan is baked(Naan should be golden brown color on top).
Take naan out of the oven and brush lightly with clear butter or ghee.
wait 2 to 3 minutes before baking the next batch of naan. It gives oven the chance to get heated again to max.
Serve Naan with Daal, Chola, Palak Paneer or any vegetable. Enjoy!

JavaScript: Alert.Show(”message”) from ASP.NET code-behind

2011-10-21T11:47:00.003-06:00

In highly interactive websites and intranet sites, you probably want to let the users know what’s going on when they delete, save, export etc. on the site. Those kinds of status messages are widely used and are often implemented by a JavaScript alert box on the web page. ASP.NET doesn’t natively support JavaScript functions from the code-behind files. You manually have to print out a script tag and add the alert() call to it.
As easy as it may be, the extensive use of the alert() status message though out a website calls for a unified and simple implementation in order to avoid duplicate code – a centralized method.
In Windows Forms it is very easy to pop up a status message by calling MessageBox.Show(“message”). It is that kind of object model we want in ASP.NET for printing out JavaScript alerts. We want Alert.Show(“message”) in ASP.NET.
Such a thing doesn’t exist so we have to create it our selves.
I’ve written a static class called Alert with one public method called Show. The implementation is as simple as can be. Just put the .cs file in the App_Code folder on your website and you instantly have access to the method from all pages and user controls.

using System.Web;
using System.Text;
using System.Web.UI;

///

/// A JavaScript alert
///

public static class Alert
{

///

/// Shows a client-side JavaScript alert in the browser.
///

/// The message to appear in the alert.
public static void Show(string message)
{
   // Cleans the message to allow single quotation marks
   string cleanMessage = message.Replace("'", "\\'");
   string script = "";

   // Gets the executing web page
   Page page = HttpContext.Current.CurrentHandler as Page;

   // Checks if the handler is a Page and that the script isn't allready on the Page
   if (page != null && !page.ClientScript.IsClientScriptBlockRegistered("alert"))
   {
      page.ClientScript.RegisterClientScriptBlock(typeof(Alert), "alert", script);
   }
}
}

Demonstration

That class of only 30 lines of code enables us to add a JavaScript alert to any page at any time. Here is an example of a Button.Click event handler that uses the method for displaying status messages.

void btnSave_Click(object sender, EventArgs e)
{
   try
   {
      SaveSomething();
      Alert.Show("You document has been saved");
   }
   catch (ReadOnlyException)
   {
      Alert.Show("You do not have write permission to this file");
   }
}
If something was saved without problems, this JavaScript alert box will apear to the user of the website

Javacript image banner random rotator

2011-08-05T11:41:00.002-06:00

Phew..enough conditions there ?

So, I needed this javascript image rotator which would pick files from a folder and show them randomely rotating through the images ...

Meh.. here is what I googled and searched and figured out

First put a placeholder on the page...

<div id="imageDiv">

<script language="javascript" type="text/javascript">

                            document.write('<center><img src="' + adBanner1 + '" id="adBanner5" width="620" height="250" border="0" alt="Some Alt Text">');

document.write('</center>');

</script>

<noscript>

                            <img src="/Images/rotate/1.jpg" id="adBanner5" border="0" width="620" height="250"

alt="Some ALt Text" /></noscript>

</div>

Now, getting a random number ...after all the first image should be random no ??

<script language="JavaScript" type="text/javascript">

<!--

rnd.today = new Date();

rnd.seed = rnd.today.getTime();

function rnd() {

rnd.seed = (rnd.seed * 9301 + 49297) % 233280;

return rnd.seed / (233280.0);

};

function rand(number) {

var result = Math.ceil(rnd() * number);

if (!result) result++;

return result

};

</script>

Now that we have a random number, lets populate the image

<script language="javascript" type="text/javascript">
//the total number of images to rotate

var ad_cnt1 = 20;

var ad1 = rand(ad_cnt1);

var link1;

var adBanner1;

var width1

var height1

var i = 0;

for (i = 0; i <= ad_cnt1; i++) {

if (ad1 == i) {

adBanner1 = "/images/rotate/" + i + ".jpg";

}

} </script>

Now... using the rotator to rotate through the images

var currentAd5 = 1;

function cycle5() {

if (currentAd5 == ad_cnt1) {

currentAd5 = 1;

}

var banner5 = document.getElementById('adBanner5');

banner5.src = "/images/rotate/" + currentAd5 + ".jpg";

currentAd5++;

}

window.setInterval("cycle5()", 5000);

Hmm so my final code would look like such:

In the head of the page I put this Javascript :

<script language="JavaScript" type="text/javascript">

<!--

function clearText(field) {

if (field.defaultValue == field.value) field.value = '';

}

function restoreText(field) {

if (field.value == '') field.value = field.defaultValue;

}

rnd.today = new Date();

rnd.seed = rnd.today.getTime();

function rnd() {

rnd.seed = (rnd.seed * 9301 + 49297) % 233280;

return rnd.seed / (233280.0);

};

function rand(number) {

var result = Math.ceil(rnd() * number);

if (!result) result++;

return result

};

var ad_cnt1 = 20;

var ad1 = rand(ad_cnt1);

var link1;

var adBanner1;

var width1

var height1

var i = 0;

for (i = 0; i <= ad_cnt1; i++) {

if (ad1 == i) {

adBanner1 = "/images/rotate/" + i + ".jpg";

}

var currentAd5 = 1;

function cycle5() {

if (currentAd5 == ad_cnt1) {

currentAd5 = 1;

}

var banner5 = document.getElementById('adBanner5');

banner5.src = "/images/rotate/" + currentAd5 + ".jpg";

currentAd5++;

}

window.setInterval("cycle5()", 5000);

-->

</script>

And where I need to rotate the images I put this div

<div id="imageDiv">

<script language="javascript" type="text/javascript">

                            document.write('<center><img src="' + adBanner1 + '" id="adBanner5" width="620" height="250" border="0" alt="Some Alt Text">');

document.write('</center>');

</script>

<noscript>

                            <img src="/Images/rotate/1.jpg" id="adBanner5" border="0" width="620" height="250"

alt="Some Alt Text" /></noscript>

</div>

By the way "window.setInterval("cycle5()", 5000);" does the rotation at 5 sec interval... you can change it to suit your needs

And you are welcome

Setting gridview edititemtemplate dropdownlist selectedvalue

2011-05-16T10:32:00.000-06:00

This is a very quick way of setting the selectedvalue of dropdownlist in gridview edittemplate...

Just add the following to your dropdownlist

SelectedValue='<%# Bind("acceptance") %>' AppendDataBoundItems="true"

The entire column would look something like this



<asp:TemplateField HeaderText="Acceptance">



                <ItemTemplate>



                    <asp:Label ID="Acceptance" runat="Server" Text='<%# calcAcceptance((int) Eval("acceptance")) %>'  />



                </ItemTemplate>



                <EditItemTemplate>



                <asp:DropDownList ID="ddlAcceptance" runat="server"  SelectedValue='<%# Bind("acceptance") %>' AppendDataBoundItems="true">



                    <asp:ListItem Value="0">Acceptable</asp:ListItem> 



                    <asp:ListItem Value="1">Required</asp:ListItem> 



                </asp:DropDownList> 



                </EditItemTemplate>



            </asp:TemplateField>

Placeholder dynamic controls

2011-05-11T09:23:00.002-06:00

So, I had to build on what I started yesterday.

Now I have a spiffy code sample for all the times when I want to add dynamic controls to placeholders..

The sample below adds 5 rows to a table with all kinds of funky controls each having its own properties set separately....

Here it goes ....drumroll !!!!!!

Front End

<table class="sofT" style="width: 100%">
        <tr>
            <td class="SubClass">
                Course #
            </td>
            <td class="SubClass">
                Course Title
            </td>
            <td class="SubClass">
                Hours
            </td>
            <td class="SubClass">
                Grade
            </td>
            <td class="SubClass">

            </td>
        </tr>
<tr>
            <td>
                <asp:Label ID="lblCrNo5" runat="server"></asp:Label>
            </td>
            <td>
                <asp:TextBox ID="tbCrNo5" runat="server" Width="300"></asp:TextBox>

            <td>
                <asp:DropDownList ID="ddlHrs5" runat="server">

          <asp:Button ID="btnAdd" runat="server" CssClass="btn" Text="Add More Classes"
                    onclick="btnAdd_Click" />

And in the backend

protected void Page_Load(object sender, EventArgs e)
{
if (Cache["tt"] != null)
{
Panel tt = Cache["tt"] as Panel;
plCols.Controls.Add(tt);

}
}

protected void btnAdd_Click(object sender, EventArgs e)

{
Panel tt = new Panel();

int courseCounter = Convert.ToInt32(lblCounter.Text);

//this is a fix needed else 5 gets repeated twice....
if (courseCounter == 5)
courseCounter = 6;

int numlabels = courseCounter + 5;

//this is getting the data for dropdownlist
DataTable ddlTable = createDdlTable();

for (; courseCounter < numlabels; courseCounter++)
{

DropDownList ddl = new DropDownList();

// Set the label's Text and ID properties.
ddl.DataSource = ddlTable;
ddl.DataTextField = "hrsToShow";
ddl.DataValueField = "hrsToShow";
ddl.ID = "ddlHrs" + courseCounter;
ddl.DataBind();

Label lbl = new Label();
lbl.ID = "lblCrNo"+courseCounter;
lbl.Text = courseCounter.ToString();

TextBox tb = new TextBox();
tb.ID="tbCrNo"+courseCounter;
tb.Width= 300;

TextBox tb1 = new TextBox();
tb1.ID="tbHrs"+courseCounter;
tb1.Width= 30;
tb1.Text = "0.00";

TextBox tb2 = new TextBox();
tb2.ID="tbGPA"+courseCounter;
tb2.Width= 30;
tb2.Text = "0.00";
tb2.Enabled=false;

//I know all this can be single Add... divided it for clarity !!

How to retain all of the dynamically added asp controls

2011-05-10T15:41:00.000-06:00

The asp.net doesn't keep control state.

So if you want to create control dynamically, you should create the dynamic control every time in Page_Load function.

You can store the dynamic control into cache, and then read it at page_load function.

Here is a example, maybe help you.

    protected void Button4_Click(object sender, EventArgs e)
    {
        Panel tt = new Panel();
        TextBox tb = new TextBox();
        tb.ID = "txtName";
        tb.Text = "hello";
        tt.Controls.Add(tb);
        PlaceHolder2.Controls.Add(tt);
        Cache["tt"] = tt;
    }

protected void Page_Load(object sender, EventArgs e)
{

        if (Cache["tt"]!=null)
        {
            Panel tt = Cache["tt"] as Panel;
            PlaceHolder2.Controls.Add(tt);

}

Update only month and day of a date in SQL server

2011-05-10T09:05:00.000-06:00

Well..sometimes Woopse happens...

We had begin dates and end dates in our database ....well somehow they got all wrong dates... years were correct and hence began the update process

Update TableName

Set End_Date =CONVERT(datetime, Convert(varchar(4),DATEPART(Year, End_Date))+'-05-01 00:00:00.000')

where (DATEPART(MONTH, End_Date)='05' and DATEPART(DAY, End_Date) != '01')

Spiffy !!!

Also, my running is going awesome... SO far so good

100 days 20 pounds challenge

2011-05-06T14:16:00.000-06:00

Ah.. am a usual average nerd who spends 10-15 hours each day on the computer, typing away to nothingness...and rejoicing in my daily intake of mountain dew, pizza and cheetos !!!

But all good things come to an end and my happy coding world crumbled down yesterday when one of my friends asked me if I was expecting a baby !!!

NO ..NO ...NO ..NO ...no no no ..NO ..NO ... and if I didn't make myself clear... OH HELL TO THE NO !!!

After that rude awakening, I have decided what I should have done long time ago. No more occasional saunterings to the gym..no more half hearted jogs... Am going 300 !! SPARTAAAAAAAAAAAAAAAAAAAAAA !!!!

I am going to run/workout every day for next 100 days ...Goal is to drop 20 pounds by the end of it.

20 pounds you say !! A very small goal !! Not for someone 5 feet 2 inches tall....

Its a ginormous task for mini me !!

And it all starts today...My plan is to workout every day and document my progress right here..

I was going to post before and after pictures but that would be too cliche.. NO ?

Let me think about that... meanwhile, 2 miles here I come !!!

string format 2 decimal places

2011-05-04T14:32:00.000-06:00

Sometimes, little things take longer than most big complicated humongous functions.

All I wanted to do was to create a datatable with formated 2 places of decimals and it wasnt working... for hours

private DataTable createDdlTable()
{
// Create a new DataTable.
DataTable myDataTable = new DataTable("gpaTable");
// Declare variables for DataColumn and DataRow objects.

// Create new DataColumn, set DataType, ColumnName and add to DataTable.
DataColumn myDataColumn = new DataColumn();
myDataColumn.DataType = Type.GetType("System.String");
myDataColumn.ColumnName = "hrsToShow";
myDataColumn.Unique = true;
// Add the Column to the DataColumnCollection.
myDataTable.Columns.Add(myDataColumn);

// Instantiate the DataSet variable.
DataSet myDataSet = new DataSet();
// Add the new DataTable to the DataSet.
myDataSet.Tables.Add(myDataTable);

// Create three new DataRow objects and add them to the DataTable
for (double i = 0.00; i <=9.50 ; i=i+0.50)
{
DataRow myDataRow = myDataTable.NewRow();
myDataRow["hrsToShow"] = i.ToString("0.00");
myDataTable.Rows.Add(myDataRow);
}
return myDataTable;
}

आपसे नहीं बिछड़े ज़िन्दगी से बिछड़े है

हम चिराग अपनी रौशनी से बिछड़े है

इस से बढ़ कर क्या होगा ताना मुकद्दर का

जिस से भी मोहबत की हम उसी से बिछड़े है

सितमगारो का है फरमान घर भी जाएगा

अगर में झूट न बोला तो सर भी जायेगा

बनाईये न किसी के लिए न ताज महल

हुनर दिखाए तो दस्ते-इ-हुनर भी जायेगा

माँ चलती है बच्चो के पाँव से जैसे

उधर ही जाएगी बच्चा जिधर भी जायेगा

C# printing column names of datatable

2011-04-21T09:24:00.000-06:00

Ah ..sometimes simple tasks baffle me...Here is a function to print column names of a datatable

private void PrintColumnNames(DataTable dt)
{
    // For each column, print the ColumnName.
        foreach(DataColumn column in dt.Columns)
        {
            Response.Write(column.ColumnName);
        }
}

C# file and directory operations

2011-04-19T13:52:00.001-06:00

So, I was facing the task for displaying the directory and file contents for each directory and could not find any good help... anyways, here are the functions as I came up with them

Displaying all the directory names along with date last modified

private string displayDirectories( DirectoryInfo parentDirectory )
{
DirectoryInfo[] diArrGE = parentDirectory.GetDirectories();
// Response.Write(parentDirectory.Name + "

");
String link = "
";
foreach (DirectoryInfo dri in diArrGE)
{
Int32 index = dri.Name.IndexOf('_');
String dirName = dri.Name.Substring(index).Replace("_", " ");
link += string.Format("
", category, dri.Name, dirName, dri.LastWriteTime.ToLongDateString());
}
link += "

{2} (Last updated: {3})

";

return link;
}

Displaying all the files in a directory sorted by date modified...

private string displayFiles( DirectoryInfo di )
{
string link = string.Empty;
StringBuilder test = new StringBuilder();
//I just need html files in the directory
FileInfo[] rgFiles = di.GetFiles("*.html");

try
{
string category = "";
if (di.FullName.Contains("Agenda"))
{
category = "Agenda";

}
else if (di.FullName.Contains("Minutes"))
{
category = "Minutes";
}
else
{
category = "Panel";
}

// Now read the creation time for each file
DateTime[] creationTimes = new DateTime[rgFiles.Length];
for (int i = 0; i < rgFiles.Length; i++)
creationTimes[i] = rgFiles[i].LastWriteTime;
// Response.Write(creationTimes.Length);
// sort it
Array.Sort(creationTimes, rgFiles);

foreach (FileInfo fi in rgFiles)
{

string[] result = fi.Name.Split(new Char[] { '.' });

string[] fileName = result[0].Split('_');

string fileNameDisplay = string.Format("{0} {1},{2}", fileName[1], fileName[0], fileName[2]);

// Response.Write(fileNameDisplay);

link = "" + fileNameDisplay + " {Last Update: " +
fi.LastWriteTime.ToString("D") + "}";

test.Insert(0, link);
}
//link = "";
test.Insert(0, "
");
test.Append("

");
}
catch (Exception e)
{

Response.Write("Error in file " + e);
}
return test.ToString();
}

I really liked the sorting function

// Now read the creation time for each file
DateTime[] creationTimes = new DateTime[rgFiles.Length];
for (int i = 0; i < rgFiles.Length; i++)
creationTimes[i] = rgFiles[i].LastWriteTime;
// Response.Write(creationTimes.Length);
// sort it
Array.Sort(creationTimes, rgFiles);

WOO WOO for that

Malformed container error in IMail server

2011-03-29T13:03:00.000-06:00

Ah... symantec decided to start marking random emails sent through ipswitch as virus...and i was alarmed..

This was the solution on IPSwitch site

This happens when something in the message did not conform to one of the RFC's for MIME Encoding. These RFC's are 2045-2049. This is usually caused by a mail client that is improperly formatting the message. There are two options to remedy the issue. You can disable the "Malformed Container Processing" or determine a way to compose the message in a way that formats the message properly. This may mean using a different client or contacting the mail client vendor.

To disable Malformed Container Processing, follow the steps below:

1.) On the server, open https://localhost:8004 in a browser.

2.) Log in with the password created during installation, otherwise click in the password field and press the enter key.

3.) Click on the "Policies" icon on the left.

4.) Click "Filtering" located in the margin.

5.) Click on the "Container Handling" tab.

6.) In the "Malformed Container File Processing" section, uncheck the "Block malformed containers."

7.) Click Apply icon, (brown arrow, second icon in upper left corner).

But the world is not that eazy... the JRE refused to run the applet needed for antivirus interfacel...

I went to Symentec site and looked around

They said the following

The problem is on client side.

Remove 1.6.0_12 Jre. It can only run with 1.5.0 JRE.
If you have both 1.6 and 1.5 installed, then browser will use 1.6 causing you problem.

I had the same issue but solved. Symantec has the solution listed here.

http://service1.symantec.com/support/ent-gate.nsf/docid/2008092215494254

So, I went to Java site next and they said to do the following to remove "older versions"

Windows 7 and Vista - Uninstall Programs

Click Start
Select Control Panel
Select Programs
Click Programs and Features
Select the program you want to uninstall by clicking on it, and then click the Uninstall button.

You may need administrator privileges to remove programs.

Windows XP - Uninstall Programs

Click Start
Select Control Panel
Click the Add/Remove Programs control panel icon
The Add/Remove control panel displays a list of software on your system, including any Java software products that are on your computer. Select any that you want to uninstall by clicking on it, and then click the Remove button.

Am just a lowly sys admin not about to challenge the mighty java folk...So, I did as they commanded and removed JRE 1.6.0_12 from my machine and VOILA... I was able to follow the IPswitch's initial instructions to the word...

Ah sometimes you really do have to step back to step forward....
