• SQL Server Need to copy All oracle tables to SQL Server 2005

  I am racking my brain on this one. I am migrating Oracle data to SQL Server and would like an SSIS package that will copy the oracle data from every table to SQL server. I already have the schema set up in SQL and a straight copy of a specified table works fine between the OLEDB source and OLEDB destination. However, when I set up a loop which sets a global variable for the table names, which are identical on both dbs, and try to set the OLEDB Source and Destination OpenRowsetVariable to the global variable, the process fails with these errors with all validation turned off: [OLE DB Source [18]] Warning: Cannot retrieve the column code page info from the OLE DB provider.

• Visual C# Calling back into same thread from activex exe

  Hi, I've got an old VB application I recently converted to c#. My C# app calls (via com) a method in activex exe activex exe calls back into main app via com When the call comes back into the c# app, it is in a new thread. In VB it used to come into the same thread. I have the STAThread attribute set on the main method of the app. Is there a way of making this happen with my new C# code Cheers Steve An EXE-based ActiveX object is an out-of-process object. out-of-process objects generally have their own thread that is used to call into other applications. Can you explain the VB application I don't see a way, without a proxy, where a VB ActiveX EXE could call another applica ...Show All

• SharePoint Products and Technologies Displaying InfoPath browser form within master page content

  Is it possible to modify the FormServer.aspx page or create a new page based on the default master page to display a form generated from InfoPath Forms Server I would like to have a consistent look-and-feel throughout the site, including when users fill out information on a form. Right now, the form open up full-screen with no other content other than the form itself. I would like the menu bars and navigation present on the screen to keep the user aware of where he/she is in the site. I'm aware that problems may arise should the user decide to click on one of these links outside of the form; I imagine it would be the same just as if the user navigated to a new URL - the form just wouldn't save.

• Visual Studio Stepping through single thread

  I have a multi-threaded application which consists of a main foreground thread and some background worker threads. Is there some way to step through my main thread and still have the background threads running, even when the main thread is stopped on a breakpoint I can confirm that Peter is correct. When stopped at a bp, every other thread is stopped. This is a limitation of how the OS works. In the case of debugging only managed code, the OS limitation doesn't come in to play (as an active debugging thread remains awake in the target process). My curiosity is piqued however - I'd like to understand your scenario as improving our concurrency and multithreaded support is a priority going forward. ...Show All
