• Visual Studio 2008 (Pre-release) Inverse Transparency

  Ok I made a post before about 'super' transparency. This is something else I've noticed: Create a WPF user control with some animation. Host this in a winform. (At this stage I need to resize or minimize/restore to get anything to show, but it's then fine) Now set the transparency key to the forms background colour to get a transparent winform. Now it's just black, like in plain WPF. But drag the window around and it will paint the animation from under the window onto the screen. Even better, put another window in front and now the animation appears in this window (any type wpf, .net) Also when the screen saver comes ...Show All

• Visual Studio Tools for Office Deleting a line break

  Hi All, I'm writing a Word Add-in which finds for a string in the document and deletes if there is a line break just before it. Can anyone help me on this TIA Pavan Hi, You can search for a paragraph mark + the string, and replace it with "nothing" or replace it with just an empty paragraph mark if you want to retain it. For example, if the string you're looking for is "find string". Search for "^pfind string". Kathleen McGrath http://blogs.msdn.com/vsto2/ ...Show All

  How do I compile my code   When I open a file, it won't let me debug or run the file.  And if I manage to get that, as soon as it runs, it just says: Press any key to continue... then it quits.  windows.h is part of the PSDK headers which is not installed with the VC 2005 Express SKU, you will need to install it separately.

• Game Technologies: DirectX, XNA, XACT, etc. Rotation about the z-axis...

  I have a square on screen (2 triangles), and I'm experimenting with rotating the thing. Rotating about the x and y axis works as expected (the thing spins horizontally and vertically), but when I rotate it about the z-axis, it goes up and down, deforms a bit, and just looks weird. As for how I'm doing it right now, I'm using Matrix.RotationYawPitchRoll(x, y, z) to get my rotation matrix. Well, you could try using Matrix.RotationZ to see if the Z-angle you're using isn't causing any problems. Other than that, we really need to see some more of your code to be able to tell what ...Show All

• Software Development for Windows Vista SQLWorkflowPersistenceService

  I just went through the AtomicTransaction lab (#8) and I was trying to figure out how the SQLWorkflowPersistenceService worked. I put some breakpoints in the code and was trying to spy on the data in the WorkflowStore tables: CompletedScope and InstanceState. However, whenever I looked at the tables, they were empty. Is there any way to spy on these tables and see what is going on under the hood Now, I should say that the example worked correctly and whenever an error occurred within the TransactionScope activity, the data was rolled back correctly. Any insights would be appreciated. Thanks, Ned ...Show All

• SQL Server Souce and Dest auto-mapping

  Hi, in my package there are several Connection Managers linking DB2 databases and there is one "fake" CM which copies the connection string of one of the other "real" CM depending of the need. Then I've made a Data Flow containing an OLE DB Source and a Destination Adapter. The Destination has a "table name from variable" access through a fixed Connection Manager, and the Source has "sql command from variable" access and uses the "fake" Connection Manager, which has "inherited" the connection string from one of the "real" CMs. The point is: When I drag the arrow from the OLE DB Source to the Destination, some mapping metadata are set, and th ...Show All
