• Visual Studio 2008 (Pre-release) DataTriggers and DataTemplates oh my!

  I've got a simple list of objects and I want to create a "details" panel that displays the object that is selected. Is there a way to create a template for each type of object in the list and place it inside a Panel. I've done it with ListView but can it be done for things that don't contain lists of things Another approach: For each different type, add an implicit template to the panel's resources. (An implicit template is one whose DataType property matches the type of your item.) Here's a sketch... <StackPanel Name="DetailPanel"> <StackPanel.Resources> <DataTemplate DataType="{x:Type myapp:Widget}"> <!-- Note: do not use x:Key here --> ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Managed -> Unmanaged Interop

  Hello to the XNA team! Looks like some pretty awesome work you've got done here guys! Me and my colleague are professional game developers considering writing "Yet Another 3D Game Engine(tm)" for XNA. So I have two questions for the team: 1.) Is there any chance of getting a preview of XNA before december so we can start developing immediately 2.) It would be nice if we could do a bit of interop between XNA, managed C++ and unmanaged C++. What are the chances of us being able to achieve this Thanks in advance! The framework itself as managed assembly could be used with any other managed language. But the Game Studio extension is currently limited to VS C# Express. ...Show All

• Visual C++ ShellExecuteEx leaking handles ?

• Windows Forms How to display a Dictionary in a gird like PropertyGird

  Hi, At run time, I created an instance of Dictionary Object which has a few keys and values . Now I want to display it inside something look like PropertyGird, one column for keys and one for values which is editable. My problem is I don't know the keys at design time, they are dynamic variables. That's why I cannot use PropertyGrid. Any ideas or walk around BR, L You could dynamically create an object at run time and give it a custom property descriptor but by the time you had done all that it might not be worth the effort :-) Is there some reason you can't use a DataGridView and make it look like a property grid ...Show All

• Windows Forms Multiple Questions about Deployment Projects in VS2005

  Hi all, I'm working with ClickOnce publishing, web deployment and setup projects, and general setup projects in the 2005 framework and have several questions: 1) Is it still impossible to configure where the physical directory of a web setup project installs the files to 2) Is it possible to work within the deployment framework to install a web application into an application pool and/or anything other than the Default Web Site, or must this still be a custom action 3) Is it possible to run an installer or other action from a component inside of an MSI without actually deploying that component For instance, I have a common set of installation actions that I want to perform via an installer class, yet I don't have a need for a ...Show All

• .NET Development ASP 2.0 web service & SQL 2005: Login failed for user ''

  My company has been working on ASP.NET web services since January 2003, with little to no issues. We've always used Windows Integrated Security to connect to the database. We started our migration to SQL 2005 and ASP.NET 2.0 last week, and we've encountered a problem at the very beginning: login failed for user ''. We are not using the new personalization stuff, at least I don't think we are, because we don't need it. Web services are for intranet use only (at the moment). It's driving everybody in my company crazy. We simply can't figure it out.

• Game Technologies: DirectX, XNA, XACT, etc. Boot Camp + XNA

  Anybody tried to run XNA on Bootcamped Mac I tried my schism game out on a bunch of computers it works just fine. However, when I tried it on a Bootcamped Windows XP Mac...The screen rotated 90 degrees...Everything worked right, controlls and such but I could only see half of my screen. A bug with the graphics device, or maybe drivers on the Mac Anybody got any ideas We've heard reports of successful usage of XNA GSE on Macs running WinXP. If you're seeing rendering problems, it's likely a driver issue. However, that hardware configuration hasn't been officially tested. ...Show All

• Visual Studio Tools for Office Disappearing Document ActionTask Panes with Word

  I've been working on a fairly complex Word VSTO application which is about complete, except for some intermitent strange behavior which happens after a document has been saved. When reopening the document ( either the saved one or starting the new one via the application word template) one of two things may happen. 1) the document action pane begins to display and then closes , leaving only the getting started task pane. it is not listed as a disabled application, logging off and back on will fix the problem as if it had been black listed 2) The Document Actions pane stays open, but the two actions pane controls which should be there are not visible, despite code (msgbox(me.ActionsPane.Controls(1).Visible) claiming the control IS ...Show All

• Software Development for Windows Vista showing workflow design view at runtime

  Hello all, I want to show the desgin view of my workflow to be displayed on run time, i.e., i want to show the design view with the particular emphasis on the activity that is executed currently. Can someboday guide me if it is possible to show the design view of the workflow on the run time does windows workflow foundation provide any facility for that if not, how can it be done manually I would really appreciate any support in this regard. It sounds like the workflow monitor example is exactly what you want. If not, it's probably a good starting point. It uses workflow tracking and the designer to monitor the progress of workflows.
