    - a problem about the config of enviroment Hi Stroller... You're working with WPF, and this is the Silverlight forum... formerly WPF/E. So.. while some of the folks here may have the knowledge to answer you, some may not. I have not tried anything WPF yet, but I do know that my images have to be png format to use with Silverlight.. is that possibly your problem Beyond that small piece of info, I'd suggest hitting the WPF group You can find them here: http://forums.microsoft.com/MSDN/ShowForum.aspx ForumID=119&SiteID=1 Good luck! -Dave Tag: Windows Presentation Foundation (WPF) thread question for MarkUpExtension => ProvideValue Visual Studio 2008

    - Listbox - Center item I'm not clear on what you're trying to do. When you say that the ListBox's Orientation="Horizontal" do you mean that its ItemsPanel's Orientation is Horizontal What do you mean by saying that the selected item should be "centered" Centered vertically Horizontally Tag: Windows Presentation Foundation (WPF) thread question for MarkUpExtension => ProvideValue Visual Studio 2008

    - About Localization Ellipsis character is just the unicode point \x2026 I believe. So the difference in display that you see is due to the difference in default font on English vs. Japanese. Try to override the font by setting FontFamily on your TextBlock and you will get the result you want. -Alik Tag: Windows Presentation Foundation (WPF) thread question for MarkUpExtension => ProvideValue Visual Studio 2008

    - Problem with WPF/Windows Forms Interop The sad part is that this may be not possible to resolve. If you look at Vista running Aero (glass etc.) and open a web browser or WMP 11 and try resizing them, you will see flicker and paint issues. I find this to be a rather offputting issue, but one that will go away as more win32 controls are converted to WPF. Perhaps you could implement your own double buffering scheme Tag: Windows Presentation Foundation (WPF) thread question for MarkUpExtension => ProvideValue Visual Studio 2008

    - Trigger a XBAP application from the browser Unfortunately, there are no better ways to interact with an XBAP. We'll be improving interop with HTML & script in future releases. Btw, don't rely on cookies. On Windows Vista accessing them is pretty broken from an XBAP. If you describe your bigger problem/scenario, we might be able to suggest a better solution for you.

    - Problem with adaptive context menus There is no one "right" way to accomplish what you want to do. Here are some possibilities: You could set the Visibility property manually when the menu opens. You can use the Opening event for that. You can setup a mulitibinding with all of the children to tie the parent's Visibility to the children's. You'd have to do this in code and would need to account for the children changing. Also, if the objects in your Items collection are not MenuItems, then be sure to use the ItemContainerGenerator to map from your items to the MenuItem containers. You could try to listen for changes to the Visibility property on MenuItems by registering a change callback and then updating the parent's Visibility property.

    - SQLMetal / visual editor - connecting to remote server I think there is no limitation on the "/server" option. You can use with remote db servers too. (of course you MUST have a proper granted user on that server instance) SQLMetal retrieves and works with your database schema. So the user that you provided for sqlmetal MUST have at least "read" right on system tables in your database. This is the same for the designer of course. And I think, ”db_datareader”, ”db_datawriter” roles are enough to use the generated classes remotely.

    - Softness of text and art in WPF apps, designed in Blend The two problems have different causes. The text blurriness is due to WPF using its own antialiasing. Altering this will require editing registry settings. See - WPF Text Blog The art being blurry is caused by WPF's ability to do sub-pixel positioning and doing it on every UIElement it can. You can fix this by setting the SnapToDevicePixels property to False on any UI element.

    - Will Orcas be faster? I would also like to hear something about this from a VS Team member. My biggest pet peeve is working with the web ui designer. Clicking on a control (textbox, label, whatever) requires 5 - 15 seconds to update the properties panel. Often times I am working so fast I end up setting the properties of a previous control becuase my dev tool is slower than me on a bad day. Additionally the automatic refactoring window that pops up and starts refactoring your project for you when you change a control name is horrendous. 1) it is NOT multithreaded and prevents the developer from continuing work while it is refactoring 2) on large projects it takes too long. I work exclusively on large enterprise solutions that tend to include 10's of thousands of pages and code files so refactoring a project like this (which 99.9999999999% of the time is useless and unecessary) is a time consuming task that should not even be done in the first place. -David Sandor Tag: Windows Presentation Foundation (WPF) thread question for MarkUpExtension => ProvideValue Visual Studio 2008

    - Custom DP binding to a Custom Class I think the problem is that you're binding to the MenuModel object instead of MenuModel. You're notifying property changed on MenuModel.Model, but the object itself is still pointing to the same instance of MenuModel. I think you can fix this by also doing NotifyPropertyChanged("") or NotifyPropertyChanged(null) which should have XAML refresh the entire object's bindings. If you'd rather not modify your object's logic this way, you could create a MultiBindingConverter, pass in the MenuModel and MenuModel.Model. In the code, just have it return MenuModel. Using this MultiBinding forces WPF to update bindings when any one of its parameters change. There should be a simple way within a standard binding to say "If any one of these changes, I also want you to refresh your binding". It's possible to get around it, but it'd be nicer and neater if a mechanism existed. Tag: Windows Presentation Foundation (WPF) thread question for MarkUpExtension => ProvideValue Visual Studio 2008

    - why double size? I suspect that the big reason was performance: Floating point calculations are performed in hardware by the microprocessor floating-point unit while decimal calculations are performed in software. Transforms often require trigonometric functions to be calculated -- and notice the Math class doesn't even include any methods to calculate Sin or Cos from decimal numbers. Double seems like overkill for coordinates, but it makes much more sense when performing transforms.

    - Check if mouse is down? For a window there are a few different events: Window.MouseLeftButtonDown Window.MouseRightButtonDown Window.MouseDown ... click events, etc. etc. If you use blend , you can click on the Window (in your Objects and Timeline view) then click on the properties tag, then hit the little lightning bolt in the upper left of the properties view. This will bring up the events. Go down to the one that says "MouseDown" and you can add in your function there. Here's some example code if you don't have blend: Window Declaration with event - Window1.xmaml <Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" x:Class="TestProject.Window1" x:Name="Window" Title="MouseDownTest" Width="1024" Height="768" MouseDown="IsMouseDown"> ... And the code behind Code behind - Window1.xaml.cs private void IsMouseDown (object sender, MouseButtonEventArgs e) { MessageBox.Show("Yay, you clicked in me!!"); } Hope that helps!! ~Elliot Tag: Windows Presentation Foundation (WPF) thread question for MarkUpExtension => ProvideValue Visual Studio 2008

Hi,

I am trying to figure out a problem related to thread in ProvideValue for a custom markupextension. Somehow, the follow code will hang visual stuido and the breakpoint won't work. It seems access Thread.CurrentThread is not allowed in ProvidValue call.

Anyone know the reason

public override object ProvideValue(IServiceProvider serviceProvider)

{

System.Diagnostics.Debug.Print("manage id = ", Thread.CurrentThread.ManagedThreadId);

...

}

Thanks

Chong

I tested this with VS 2008 Beta2 (coming out very soon)...and I didn't have this problem.

So this is likely either: a fix in .Net or a fix in VS that you'll be able to use soon (Beta2 coming this week...)

Hope that helps.

Thanks, Rob
