Making jQuery UI’s Dialog Work With ASP.Net

Nicholas — Thu, 25 Jun 2009 22:06:30 -0700

You might have come across this problem in your travels, I know I have. Basically if you’re using jQuery UI’s Dialog and have a <form runat=”server”> inside of that dialog, your postback is not going to work. What’s going on?

jQuery UI is taking the dialog DIV content and moving it outside of the <form runat=”server”> tag. This makes your postback no longer function as expected.

Luckily we can fix this fairly easily with jQuery itself.

var dlg = $('#divMyDialog').dialog({
                    autoOpen: false,
                    modal: true,
                    width: 400,
                    resizable: false,
                    overlay: {
                        background: "black",
                        opacity: 0.5    
                    }
                });
dlg.parent().appendTo(jQuery('form:first'));

The special logic lies in the last line—using the reference to our created dialog, we get the parent container and move it back to the first <form> on the page. After that, all is well.

I forgot to point out that it comes with a little remote for your steering wheel that worked great. Enjoy my first video review.

ASP.Net Trick: Getting rid of viewstate on DropDownLists

Nicholas — Sun, 22 Feb 2009 22:11:23 -0700

If you’ve used ASP.Net for any amount of time, you quickly realize how much it loves to dump into the viewstate. Now, I’m not claiming I’m a saint in this area, but I have been learning as I go to recognize what operations will fill the viewstate and work to prevent them.

One trick I learned recently is to re-bind your DropDownList on every postback, inside of the DropDownList’s Init event handler. You can also pull in the postback value from the Request.Form collection and set the DropDownList’s SelectedValue to what it should be. Observe the following example:

   1: Protected Sub ddlMyDropDownList_Init(ByVal sender As Object, ByVal e As System.EventArgs) Handles ddlMyDropDownList.Init

   2:     Dim db = New MyDataContext()

3:

   4:     Dim q = From s In db.States _

   5:             Order By s.StateName _

   6:             Select New ListItem(s.StateName, s.StateAbbrev)

7:

   8:     ddlMyDropDownList.Items.AddRange(q.ToArray())

9:

  10:     Dim r = Request(ddlMyDropDownList.UniqueID)

  11:     If r IsNot Nothing Then ddlMyDropDownList.SelectedValue = r

  12: End Sub

Don’t forget to set “EnableViewState=False” on your DropDownList.

Help: My XBox 360 won’t stay connected to XBox Live!

Nicholas — Sun, 22 Feb 2009 22:02:17 -0700

In the entire time I’ve had my XBox 360, I kept getting disconnected from the XBox Live service after 30 minutes or so, no matter what. I could be downloading or playing a multiplayer game, it didn’t matter. I thought at first that it was my wireless setup (I am using a Netgear wireless router as a “client” and going straight into the XBox 360) but it turns out I was wrong.

The XBox Live service has a “heartbeat” and if it can’t connect to specific ports after specific times, it assumes your connection is garbage and disconnects you. If you’ve got a UPNP (Universal Plug-n-Play) router, this doesn’t really affect you, since your XBox 360 tells your router to forward those ports and everyone’s happy. But I do not have UPNP compatible router; in fact I have the semi-expensive business-class Cisco PIX 501 firewall. Therefore these ports needed to be routed manually.

According to this Microsoft KB article, you need to open/forward the following ports:

TCP 80
UDP 88
UDP 3074
TCP 3074
UDP 53 TCP 53

My problem is now solved. I hope this can help someone else out there.

Slacker Radio on the iPhone: A Review

Nicholas — Sun, 22 Feb 2009 21:35:08 -0700

I had heard of Slacker Radio, but always thought it had a physical device that you needed to purchase in order to listen to the music. It turns out that’s not entirely true. You can actually listen online in your web browser (similiar to Pandora) for free all you want. They also have an excellent iPhone app that gives you a lot of the same functionality as their hardware device, but for free. I’ve been using the iPhone app on and off the past month, so I’m going to be basing my review on that.

First off, I have a regular iPhone. It doesn’t do the faster 3G data transfers (just EDGE.) I have tried other radio applications on my iPhone and found that they either sounded terrible, or skipped/stuttered all of the time (due to the aforementioned EDGE vs. 3G speeds.) Slacker works differently than other streaming radios in that it actually sends you the entire song as fast as it can. This means the odds of it stuttering are pretty slim to none, even on the slower EDGE network. Once a week I drive to Riverside (easily 2 hours each way) and I have only experienced a few “drop outs” of service in that time.

Slacker is different from Pandora in that it has pre-programmed “Stations” of music, similiar to picking a genre on your iPod or type of radio station in your car. The selection is pretty good, too. I sometimes listen to “Electronic Hits” and am surprised at some of the old/rare gems that it chooses to play.

Slacker is also different in that it allows you to skip songs and also ban songs/artists that you no longer want to hear on that channel. If you don’t pay for the service, you are allowed 6 song skips each channel each hour. If you pay their modest subscription fee, you’re free to skip as many songs as you want. No limits. And you can request to hear any artist or song instantly as much as you want.

I recently cancelled my XM radio subscription, so Slacker has basically replaced it. I really think this is the future of in-car/portable radio, due to more and more cell phones being internet-capable. I was even able to use it in the “middle of nowhere” during a vacation getaway up in Julian a few weeks back. I hooked my iPhone up to a set of speakers and put on the Slacker “80s, 90s, & Todays Hits” station as background music to just hanging out with friends. Worked great.

I really recommend this application, especially if you’ve got an iPhone and are tired of hearing the same ol’ stuff in your car. Check it out and let me know what you thought in the comments below.

The Incredible Special Effects of “Benjamin Button”

Nicholas — Sun, 22 Feb 2009 21:18:16 -0700

I haven’t seen the movie yet, but when I saw the trailer, I was instantly intrigued. Being a film fanatic (and growing up wanting to work in Hollywood doing special effects) I wondered how they pulled off Brad Pitt’s aging in reverse. Turns out they made a website all about the special effects (no doubt to assist them in winning the 2009 Academy Award for Best Visual Effects, Best Makeup and Best Art Direction.)

Fallout 3: Can’t get Anchorage DLC to work?

Nicholas — Sat, 07 Feb 2009 00:55:52 -0700

No worries. I think I can help. See, I purchased the Steam version of Fallout 3, and when I installed Steam originally, I put it in a location different than the default (\Program Files\Steam\ is the default, I opted for simply \Steam\). The new Operation: Anchorage DLC (download content) for Fallout 3 doesn’t seem to like the fact that my copy of Fallout 3 is in a different place.

Upon starting the game, it looks like the DLC is loaded (it even shows up in the main menu’s “Download” section) but you will never receive the radio signal in your Pip-Boy to start the quest.

If this is your situation, and you’re running Vista, you’re in luck. You need to create a symbolic link. This is basically a “fake” directory that links to another directory.

Click the Vista logo and type “cmd” in the search box. If you’re not running as an administrator by default, you need to hold down CTRL+SHIFT when you hit enter in order to get admin privilages.
Type in cd “\Program Files\” – or if you’re running Vista 64 like me, cd “\Program Files (x86)\”
If you already have another Bethesda game installed (like Oblivion) you’ll want to do this:

cd “Bethesda Softworks”
mklink /D “Fallout 3” “[put path of your actual Fallout 3 directory here]

Otherwise, if you don’t have any other Bethesda games, you need to type this:

mklink /D “Bethesda Softworks” “[actual Fallout 3’s parent directory here]

Note that I said PARENT directory on that last one. So if Fallout 3 is installed in D:\Games\Fallout 3\, you will want to provide the path D:\Games\ as the second parameter.
Everything should be good to go! Run the game and enjoy. Within a minute or two you should get the radio signal.

Hopefully this helps someone else out. I was getting frustrated, having spent the money on the DLC and not getting anywhere. And tsk tsk on Bethesda for not making this issue more well-known.

Fallout 3: Video/Display Freezes, sound keeps going

Nicholas — Sat, 07 Feb 2009 00:35:17 -0700

Ever since Bethesda came out with the 1.1 patch for Fallout 3, I couldn’t play the game anymore. Once I got into the game and started wandering around, I’d randomly “freeze” up… the video would stop updating, but the sounds/music would still play. Keyboard clicks and mouse clicks did nothing, requiring me to ctrl+alt+del and kill the task manually.

It looked like I was SOL until the next patch, but I found some help online:

The game engine has some issues with processors that have more than 2 cores. You can force the game to only use two of them and it will stop the freezing. I haven't had it freeze once since I did this several days ago.

Open up the fallout.ini file in: My Documents\My Games\Fallout3
Find the line:

bUseThreadedAI=0

change it to:

bUseThreadedAI=1

Add another line after it and insert:

iNumHWThreads=2

This will limit the game to 2 cores and prevent the engine bug from causing the game to freeze.

Surprisingly, this worked like I charm. I do indeed have a quad core processor, so it sounds like this was the culprit. Why 1.1 broke the game for me.. I have no idea. It sounds like Bethesda needs to do some better testing on multi-core processors.

Hopefully this helps someone else out there!

I always love the concept of random people doing something unexpected in a crowd. It’s funny to see how people react.
