• Software Development for Windows Vista Compiling DirectShow Samples with Visual Studio .Net 2005

  We've just purchased .Net 2005 and would like to compile the DirectShow BaseClasses supplied with the Platform SDK.  DirectShow documentation (in the on-line version of the MDSN library) states that there should be a .dsw file in the BaseClasses folder... but there is none.

Im in the beginning phases of a project and i need to create methods, etc. that can be easily used without knowing the ...Show All

• Visual Studio AddNamedCommand2 - Toolbar and menu icons

  I was glad to see AddNamedCommands2 added to the DTE.Commands since it lets you control the icons/text displayed. I hated having text in my toolbars with VS2003. But I'm still having trouble getting what I want. I want to display icons only in the toolbar, and icons+text in the menu (as is typical for most applications)  I'm trying to turn on toolbar and menu icons for a command.

• Smart Device Development OnInitDialog/OnSetActive call sequence appears to have changed

  It appears that with MFC 8/VS2005 the call sequence for activating a property sheet and its corresponding pages has changed. We are seeing the following: OnInitDialog() fires for the first property page (the one all the way to the left). OnSetActive() fires for the first property page. OnInitDialog() then fires for each remaining property page, from left to right. With eMVC++, I don't believe OnInitDialog() would be invoked until ...Show All

• SQL Server Unexpected function sequence error when using SQL_CO_FFO on stored procedure

  Hi all, In my ODBC program, I try to execute a stored procedure returning a unique result set, by using a fast forward cursor (SQL_CO_FFO), but I get a "Function sequence error" when fetching the first row. FFC forces the ODBC driver to use sp_cursoropen, which is fine for me because I need multiple active SQL statements. I appears that the content of the stored procedure matters. When the procedure implements only a simple SE ...Show All
