• Visual Studio 2008 (Pre-release) GridViewColumn Limitation

  I have a problem with GridViewColumn when using CellTemplateSelector. The solution, I believe, is to allow a "DataContext" property on GridViewColumn. But first, the problem... I have a data aquisition application in which I want to define two (only) templates related to quality control: one for "good" data and one for "bad" data. Unfortunately the template must also supply the data binding path, meaning that I have to have copies of the templates for every piece of data that I might want to display. This defeats the purpose of a template as far as I am concerned because it conserves no effort. To illustrate the problem I have concocted the XAML file below. My application doesn't use XML data, but this was the ...Show All

• .NET Development creating ntfs on raw disk

  Hi, Iam trying to format ntfs filesystem on rawdisk. Iam using the following ioctls. 1. IOCTL_DISK_CREATE_DISK // Initialize to a basic disk 2. IOCTL_DISK_SET_DRIVE_LAYOUT_EX // which creates partition. 3. I used IOCTL_DISK_VERIFY // verify partition in the disk. 4. IOCTL_DISK_UPDATE_PROPERTIES // making OS know about the partition. 5. Now to use format I used FormatEx as mentioned in the link http://www.sysinternals.com/SourceCode/fmifs.html ). These steps doesnt work for the first time but it works for secondtime and successfully format on given physical drive \\.\PHYSICALDRIVE4 . Also these ioctls doesnt when more disks were connected to system. Has anyone faced such a problem. Ple ...Show All

• SQL Server SQL Server Setup failed to retrieve the SSL Certificate Name

    When I try to install SQL 2005 Developer September CTP on Windows XP Professional  it returns an error "SQL Server Setup failed to retrieve the SSL Certificate Name" . I was using a certificate from SelfSSL but removed it. Still no luck This appears to be an issue with SQL Reporting Services. If I don't install Reporting Services then I can install SQL 2005. I'm guessing that Reporting Services is now requiring a certificate and doesn't like the SelfSSL certificates Any ideas I got the same error as well.  Selfssl had been previously used to install a cert with IIS for ssl testing.  I removed the cert from iis and reporting services installed fine. Good luck Jay Skelly Microsof ...Show All

• SQL Server Is it possible to enable TCP/IP connection to SQL Server programmatically? Is there any function in SMO?

• Microsoft ISV Community Center Forums subscript out of range

  I am getting an error when running the script Do While (Not (Workbooks(bookmonth).Worksheets("by associate").Cells(4, i) = "dsl") Or Not (Workbooks(bookmonth).Worksheets("by associate").Cells(4, i) = "hsi")) I am uncertain why this is coming up. i is currently set to 1, so it should be starting to search in cell a1. I can not see anything wrong with the code that would produce a type mismatch on that line. Any value contained in the cell A4 would be compared to the two string values and would either proceed into the loop or pass over it. What value do you have in the cell when the test raises the error ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Alpha blending BUG in XNA

  It would seem as though the relevant blending render states have no effect when applied through MY code, but when they are set through the SpriteBatch class, they seem to work as intended. Note the following code: //spriteBatch.Begin(); // spriteBatch.End(); graphics.GraphicsDevice.RenderState.AlphaBlendEnable = true ; graphics.GraphicsDevice.RenderState.AlphaBlendOperation = BlendFunction .Add; graphics.GraphicsDevice.RenderState.AlphaSourceBlend = Blend .SourceAlpha; graphics.GraphicsDevice.RenderState.AlphaDestinationBlend = Blend .InverseSourceAlpha; The effect here is that when I run my test with THIS code RIGHT before the draw calls, alpha blending is NOT enabled, although alpha testing does indicat ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. The Content Pipeline and my Scene Graph

  I implemented a scene graph. Items in the graph are of type Entity. StaticVisual, a subclass of Entity, takes a Model as a constructor parameter. Using the content pipeline and contentManager.Load<Model>("assetName") things seem to be working smoothly. Now, I want to extend the content pipeline to have complete scenes be content. I'm not sure how to do this without writing a ton of redundant and error prone code... My idea is to write a Model Processor and look at the node's names in order to decide which types of Entities to instantiate. I'd modify my StaticVisual class to take a ModelMesh (or a ModelMeshPart ) as a parameter and in theory I could construct a whole scene graph. I'd like to write single generic pai ...Show All
