An easier way to do this is to use a Grid with two columns, both of which are the same size. Don't set any size info in your listboxes, just assign them to the appropriate grid column and let the grid take care of laying your items out.

Visual Studio XAML Editor Hotfix

For you WPF/Silverlight users that experience the frequent crashes of Visual Studio while editing XAML…

I indirectly came across this issue filed on Connect:

Frequent "Microsoft Visual Studio is Busy" hangs after installing VS2008 SP1[^]

I had been using the March hotfix, which diminished the frequency of crashes but didn’t eliminate them.

Turns out there’s a May hotfix:

KB963035 - VS2008 SP1 sometimes hangs irretrievably after WPF Designer[^]

Jury’s still out, but I haven’t had a crash yet in two days….I’m going to keep hammering on it with my fingers crossed…

Where did you place that button? Is it in Silverlight User Control or ASP.NET?

Please check this HTML Bridge[^] if you like to interact between Managed Code of Silverlight and Javascript.

Hope it helps.

You shouldn't mess with that as it's set to what the operating system says it should be. That being said...

The only thing I know to suggest is to get expression blend and scrape the window class template from it, and work from that. You'll probably have to write a class that inherits Window, and add an attached property.

Like John stated - the OS handles that.

If you rip the Window template using blend, you still won't be able to change the
title bar.

If you must provide a custom title bar, you can use a Window without a title bar
and provide your own. For example, see Nish's article:

WPF tip : Using a custom title bar[^]

Note you won't get any of the visual cues provided by the OS Smile | :)

tv tuner and directShow

Does anybody have any insight on audio streaming through a tv tuner in a vb app? I'm using a directshow2005.dll. I have the video end of it working fine, but the audio does not work. Is there a way to check the graphBuilder or the assigned pins? Or does anybody have any better suggestions? Maybe an updated dll or or completely different one? I was reading some other forums and this seems to truly be a tough topic in everything before 3.5 .net framework.

Hi,

I am working on an application in which we have to retrieve the attachment files from given Gmail Id using Pop3 and save them in a folder. I worked this with yahoo mail, but now I have to do this with Gmail too. As Gmail have some security I am notable to directly connect to it directly. I came to know that using SSlconnection we can connect to Gmail. But I don't know how to do this.

If any one have any idea to solve this please reply me.

Thanks in Advance.

Well, in WPF I'd do this by... no wait, your question has nothing whatsoever to do with WPF. OK, change of tack, in WCF I'd do this by... no wait, it's not WCF either. Silly me, it must be WF - well, I'd start by... no wait not WF either. You haven't, um, got the wrong forum by any chance?

How do I get from data bound to a row in a ListView to the UI representing the row so I can apply a style to the row?

I'm using data binding to populate the rows of a ListView. Then an event takes place where I have to change a value in a particular column in the row and I'm successfully doing that. But now to grab the user's attention I want to change the color of the text in the row. But all I have is a reference to the data object whose public properties I use to populate the row. But how do I get a reference to the UI object that presents this data visually in a row within the ListView so I can change the style of that row?

As you can see, I'm still puzzling over how to get back and forth between the data and the UI presenting it visually. I know there's a difference. I just don't know how to get back and forth. This sounds like a fundamental WPF question and is another example of fundamental knowledge that I have not yet mastered, but once I get this one answered, a lot of pieces of the puzzle are going to fall into place.

Why do you need to use XAML ? I don't see how you can, I mean, how would you work with the resultant file if not in code behind ?
