• Visual Studio Team System ASP.NET Unit Test Error _web request _ completed without running test_

  I am often getting errors like this one: The web request 'http://localhost:1850/Tests/Default2.aspx' completed successfully without running the test. This can occur when configuring the web application for testing fails (an ASP.NET server error occurs when processing the request), or when no ASP.NET page is executed (the URL may point to an HTML page, a web service, or a directory listing). Running tests in ASP.NET requires the URL to resolve to an ASP.NET page and for the page to execute properly up to the Load event. The response from the request is stored in the file 'WebRequestResponse_recordClickTest.html' with the test results; typically this file can be opened with a web browser to view its contents.

• Visual Basic Unsigned Arithmetic and overflows

  I've had this discussion before with unint64s. Setting what would normally be the sign bit causes an overflow. Now I'm seeing this in unint32s. Dim a As UInt32 = System.Drawing.Color.Black.ToArgb will cause and overflow. Dim a as Uint32 = now.ticks and &hFFFFFFFF will cause an overflow depending in the time. This should not be. What it means effectively is the UInt32 is actually UInt31. Hey Mike, I'll find the link for you in just a moment. Here's THE Problem: Dim a As UInt32 = &H80000000 is not legal Dim a As UInt32 = &H80000000L is legal. So as you say the ISSUE is with the constant. However I'm going to call it a problem because a CONSTANT should be CONSTANT. I am an enginner th ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Creating .tga UVwrap for XNA?

  Hi, I am new to this, but I have 3ds max and the DirectX SDK along with XNA GSE. In the tutorial they have a model (.fbx) and its texture wrap (.tga). I want to use a different model. I import one into 3ds max and it loads and the textures/materials are wrapped on it. I export the model to .x (which XNA can use too I believe) and now need to create a .tga that XNA can wrap it with. Thanks for the tip to this. Darren You have to assign the material to the object in 3D Studio MAX. I would search around for some tutorials on the subject that would help you get started. http://search.live.com/results.aspx q=3D+Studio+MAX+Texture+Tutorial ...Show All

• Windows Forms System.IO.FileNotFoundException In Windows Application

  Hello! I have developed a windows Application using VS2003 (VB.NET) to enable my client to export Crystal Reports 8.0 to PDF,HTML and Excel formats. Since the Excel export that comes with VS.NET is not very user friendly, I used Interop.CRAXDRT.dll reference to export the reports to Excel. The application workes fine on my workstation, but when the client installed it, he is getting *** System.IO.FileNotFoundException: File or assembly name Interop.CRAXDRT, or one of its dependencies, was not found**** error. I have tried everything I can think of to resolve this in vain. The interop.craxdrt.dll is in the application bin folder. I made the client copy the file to his system32 folder. Gave the application folder full control permissio ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Parameters for content processor

  Is there currently any way of providing parameters to the content pipeline For instance, if I had a huge terrain that I want to convert into blocks within the pipeline, it would be nice to set a parameter for the block size within the IDE's properties panel for the asset, alongside the ContentImporter/ContentProcessor settings. If not I guess I'm going to have to create an XML file to describe the terrain, and import that instead. Not half as nice.

Does that mean the votes for it will still be looked at at a later date, or not ...Show All

• Visual Studio Team System File Explorer in VS2005 incredibly slow

  When I try to navigate down the directory structure using the file/open drop down in VS2005, it takes about 30 seconds to navigate down each level of the directory structure. If the level I want is 6 levels down it wastes 3 minutes getting there. Thank you for the suggestions. In fact I am running VS2005 locally and not using the Source Code Explorer at all. The File/Open/File drop down was what I was referring to. A few random remarks made me think of mapped drives, and it turns out that I had one connecting through a VPN. There was no problem when the VPN was connected, but when it is disconnected that's where the 30 seconds delay happens. It doesn't affect the windows file explorer in the same way howeve ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. F14 XNA Game with Full Source

  Well here it is. I finally got my first game into a releasable state. Screenshot, video, and full source available after the jump. http://aroganworld.blogspot.com/2006/09/f14-xna-game.html I couldn't have done it without the great help from this forum (and all those xna sites). Let me know what you think. Yeah let me know if you have any issues. I did d/l the zip, unzipped it to a new directory, compiled and did a test run so I think it should work. Also, I just remembered I forgot to hook in the game over voice clip. Oops. It's in the sound bank, I just forgot to trigger it so I'll probably update the zip tonight when I get home. It was a late night last night. Damn you Microsoft for making this time si ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Converting from a string to Texture2D

  I am new to XNA and have been playing around a little bit with a project. I am currently trying to call .Draw on a SpriteBatch object and dynamically set the paramater for the Texture2D. The line of code looks like this: spriteBatch.Draw(<Some String Here>, new Rectangle (currentMaze[0, 0].position.X, currentMaze[0, 0].position.Y, falseFalseFalseTrue.Width, falseFalseFalseTrue.Height), Color .White); This piece of code would be in a loop and the name of the Texture2D paramater would change. I tried the following line of code: spriteBatch.Draw((Texture2D)<String here>, new Rectangle (currentMaze[0, 0].position.X, currentMaze[0, 0].position.Y, falseFalseFalseTrue.Width, falseFalseFalseTrue.Height), Color .White); ...Show All

• .NET Development Reading a DataReader from two places at the same time.

  I have a SqlDataReader which returns some data from a database. I would like to insert the data from this DataReader into two different tables on two different servers, using two SqlBulkCopy instances. Somehow my SqlBulkCopy objects should read the same DataReader in parallel, so I won't have to read my data twice from the source. The amount of data is quite large, so I wouldn't cache them, for example into a DataSet. How would you solve this problem The only idea I could think of is creating a wrapper over the DataReader, which implements the IDataReader interface, and which can be read in parallel from two different threads. However I don't know how this would perform, as each thread would block after each row of data, and th ...Show All
