Which captured the Event Behavior: KeyPress which was used to trigger an action after the Enter Key was pressed.

During a project to allow our admins to change the manager field in our AD LDS Identity Store I was coding a Textbox to be triggered with the tab key, but low and behold they TAB key is not captured by default by the KeyDown, KeyPress or KeyUp Events.

Per the Microsoft Articles:

http://msdn.microsoft.com/en-us/library/system.windows.forms.control.keydown.aspx

http://msdn.microsoft.com/en-us/library/system.windows.forms.control.keyup.aspx

Certain keys, such as the TAB, RETURN, ESC, and arrow keys are handled by controls automatically. To have these keys raise the KeyDown event, you must override the IsInputKey method in each control on your form. The code for the override of the IsInputKey would need to determine if one of the special keys is pressed and return a value of true. Instead of overriding the IsInputKey method, you can handle the PreviewKeyDown event and set the IsInputKey property to true.

Note the IsInputKey method must be set per control, so there is no need to turn it back off for other controls on the same form.

So in this example I start with a basic form with two labels, two textboxes, and a status bar to show when the TAB or ENTER keys are captured.

For the Event Behaivior: PreviewKeyDown for $textbox1 I setup the following code:

$textbox1_PreviewKeyDown=[System.Windows.Forms.PreviewKeyDownEventHandler]{
     #Event Argument: $_ = [System.Windows.Forms.PreviewKeyDownEventArgs]
     $_.IsInputKey = $true
}

For the Event Behaivor: KeyDown for $textbox1 I setup the following code:

$textbox1_KeyDown=[System.Windows.Forms.KeyEventHandler]{
#Event Argument: $_ = [System.Windows.Forms.KeyEventArgs]
      If ($_.KeyValue -eq 9) {
           $statusbar1.Text = “Tab key was pressed”
           $textbox2.Focus()
           $textbox2.Clear()
     }
     Else {$statusbar1.Text = $_.KeyValue}
}

Notes:

     1. I used the KeyDown event because the KeyPress event is not raised by noncharacter keys; however, the noncharacter keys do raise the KeyDown and KeyUp events.

     2. I use $textbox2.Focus() to move to the next control because the TAB key is no longer coded to complete that default action.

Set $textbox1 Events to the previous code sets.

To show the different between the two examples I coded $textbox2 Event Behavior: KeyPress to capture the ENTER key

$textbox2_KeyPress=[System.Windows.Forms.KeyPressEventHandler]{
#Event Argument: $_ = [System.Windows.Forms.KeyPressEventArgs]
      If ($_.KeyChar -eq 13) {
           $statusbar1.Text = “Enter Key was pressed”
           $textbox1.Focus()
           $textbox1.Clear()
     }
}

Set $textbox2 to the previous code set.

As you may have noticed in the Event to capture the TAB key we used KeyValue and in the Event to capture the ENTER key we used KeyChar.

KeyCode, KeyData or KeyValue must be used because KeyChar cannot capture the following Keys

The TAB key.

INSERT and DELETE.

HOME.

END.

PAGE UP and PAGE DOWN.

F1-F2.

ALT.

Arrow keys.

For more details about the differences between KeyCode, KeyData, and KeyValue:

http://msdn.microsoft.com/en-us/library/system.windows.forms.keyeventargs.keycode.aspx

http://msdn.microsoft.com/en-us/library/system.windows.forms.keyeventargs.keydata.aspx

http://msdn.microsoft.com/en-us/library/system.windows.forms.keyeventargs.keyvalue.aspx

In my next post I would like to show examples of how to use KeyChar to to control the field format of a textbox used for items like ZipCode or Telephone Numbers.

So based on being able to code an If statement in either of the following fashions:

If ($someAttribute -eq $false -or $someAttribute -eq $Null){

}

or the following:

If (($someAttribute -eq $false) -or ($someAttribute -eq $Null)){

}

Then we should be able to do a combined effort:

If (($someAttribute -eq $false -or $someAttribute -eq $Null) -and ($someUser -eq “UserID123″)){
       Write-Host “Switching to True”
       Set-QADUser $someUser -Service “MyDomain.org” -ObjectAttributes @{$someAttribute = $True}
       If (!$?) {Write-Host “Error: $($error[0])”}
}

So if $someAttribute is either $false or $Null AND #someUser equals “UserID123″ then do something… in this case I switch the Attribute someAttribute to $true and do some error checking.

In this examble I have three basic controls a textbox,a button and a listbox.  I am using the textbox as a Search Textbox, after entering text to search the end user can either press Enter or the ‘find’ button.

First add the Event Handler for the Textbox to response only to the Enterkey.

Next add the Event Handler to search Active Directory using the text from the TextBox($txbFind) after the button($btnFind) is single clicked.

Next the code for handler_button1_Click. First the Event handler clears the listbox ($lstResults) then it searches Active Directory with the text from the Textbox ($txbFind). Then if the results if not null, the handler will list the results in the listbox($lstResults)

$handler_btnFind_Click={
$lstResults.Items.Clear()
$Users = get-qaduser $txbFind.text -service ‘MyDomain.edu’ -sizelimit 0 -includedproperties displayName | Sort displayName | select displayName
 if ($Users -ne $Null) {
  foreach ($User in $Users){
   $lstResults.Items.add($User.displayName)
  }
 }
}

Lastly we add code to the Event handler for the textbox to trigger the button($btnFind) when the Enter Key is pressed and give focus to the listbox($lstResults).

$handler_txbFind_KeyPress=[System.Windows.Forms.KeyPressEventHandler]{
If ($_.KeyChar -eq 13){
 $btnFind.PerformClick()
 $lstResults.Focus()
}
}

The results show the matching users in the listbox

Using this code I created an admin tool that modifys anything from address to exchange administration. Happy Coding!

So I start with a basic form (Two Tabs and a Button)

Then on the Events tab of $button1, double click ‘click’

Add the following code to the Event handler:

 $handler_button1_Click={
#TODO: Place custom script here
     If ($tabpage1.Visible -eq $true) {
          $tabcontrol1.SelectTab(‘tabpage2′)
     }
     ElseIf ($tabpage2.Visible -eq $true) {
           $tabcontrol1.SelectTab(‘tabpage1′)
     }
}

Clicking the button switches from tab to tab. Way cool!

I am excited to see some focus around Active Directory and Forefront Identity Manager at a conference especially since Forefront Identity Manager was just released to manufacturing. One of my fears in attending this conference this year was that FIM would be released after TEC 2010 and covered in greater detail at TechED 2010, now with the release of FIM I hope that is not the case. I have already seen some vendors providing extensions to FIM so this may be the best year to go to TEC so far.

I definitely will be posting some more information and pictures during the event. Feel free to email me with any suggestions around the conference or questions you would like to be asked. ITNotes@gmail.com

This script basically converts everything to lowercase then capitalizes the first letter of each word.

function ToProperCase ([String]$in)
{
 $in = $in.Tolower()
 $textInfo = [System.Threading.Thread]::CurrentThread.CurrentCulture.TextInfo  
 return $textInfo.ToTitleCase($in)
}

Example of use:
$Title = “ITNOTE DOT NET”
ToProperCase($Title)

Returns:
Itnotes Dot Net

Complete Script

function ToProperCase ([String]$in){
 $in = $in.Tolower()
 $textInfo = [System.Threading.Thread]::CurrentThread.CurrentCulture.TextInfo
 return $textInfo.ToTitleCase($in)
}
$Title = “ITNOTE DOT NET”
ToProperCase($Title)

As noted by Lee, here is a oneliner contributed by Jonathan Noble at http://www.jonoble.com/. Thanks Lee.

(Get-Culture).TextInfo.ToTitleCase(“THIS IS MY STRING”.ToLower())

I am always in favor of shorter scripts nevertheless I also favor functions, so here is a much shorter function:

function ToProperCase ([String]$in){
return (Get-Culture).TextInfo.ToTitleCase($in.ToLower())
}

Thanks for reading!
