• Visual Studio 2008 (Pre-release) Problems with WCF

  Hi everybody, I have a problem with Indigo. I have installed the WinFX following the instructions. Then I try to build the first application.

• Game Technologies: DirectX, XNA, XACT, etc. Releasing - does the DirectX version installed matter?

  Hi there. I have just finished a game and I would like to know the following. Currently I have only DirectX SDK February 2006 installed, but lets say the user has another version of DirectX installed, will it be able to run the game This is a 2D game. Do I need to install all the SDK versions so the game will work on all 9.0 version or what Do I have to do something like that so I can be sure the user only has to worry if he has DirectX 9.0 installed. I really don't want him to worry about anything else. It depends. If you are in C++/Native and you don't use d3dx then any version of DirectX 9.0c will have all the files you need. ...Show All

• Visual Basic COM Interop, Property Get,Let,Set Interface Attribute?

  Hello, We are in the middle of a rather large piecemeal upgrade of our VB6 system to .NET 2.0.  We started in 1.1 and have sence migrated that code to 2.0.  We have done a few of our libraries to this point, and are gearing up to upgrade a lot more of them in the next month or so.  We ran into a problem in our first library that required a rather nasty fix and I was hoping someone could point us to a better solution. Problem:  The problem we are having is in VB6 we defined many properties of type Variant for the sole purpose of being able to store Null.  These properties are typically used t ...Show All

• Visual Basic Opening command-line app in outlook

  I am modifying an application so it accepts command-line parameters. This part of the code works. Users of the application get automated emails from the application that says "work request 123 with activity xyz has been assigned to you." Currently, they have to go to the application and search for that particular request/activity. I want the emails to also have a command line so the application would open to that specific req/activity. For example \\c:\appfolder\appname.exe xyz-123 The problem is MS outlook (the only email client currently used) ignores the command line portion. How can I get the two to act as one, dispite ...Show All

• Visual Basic How do make progress bar work on the working interface?

  Hi, I am programming two interfaces for a Windows application: interface1 is the main interface, and there is a button on it. When I click the button on the interface1, the interface2 should be shown. But it will take long time to display the interface2 (the working interface), since the interface2 is doing many computings. I would like to set a progress bar so that the interface2 can display immediately after I click the button on the interface1. After the interface2 display, we can see the progress growing step by step. Could anyone provide a sample program Thanks in advance. Moreover, I use the following codes to make the interface2 ...Show All

• Windows Forms Font rendering problem (cut-off, spacing)

  Hi, I have a very strange behavior on some fonts like Verdana, size 6.75f. Often the labels simply get cut-off and don't draw fully or there is too little spacing between the letters. See this screenshot: http://www.kingvest.de/prob.png Words like "of this" and "of it" appear as "ofthis" and "ofit" although definitely have a space in between ;) Also, in the lower half of the screenshot, the quotes like 422,86 get cut off although the labels are on autosize within a flow panel. Anybody has an idea why this is Thanks, Tom If you're using VS 2005, make sure you've got Application.SetUseCompatibleTextRendering ...Show All
