• Software Development for Windows Vista Windows Worflow Designer

  Where can I get documentation and examples of using the cancelActivity (located on the second tab of the workflow designer - on the bottom).

• Visual Studio Tools for Office A very technical (I think) VSTO startup question

  What is different on a system before VSTO customized document is loaded and after Let me explain. We've got a Word customization that takes 58 seconds to load the first time after a reboot, but only 18 seconds thereafter. Our customization is installed in the GAC, is NGEN'd, and rather large. We have a shimmed managed Word addin that starts .NET CLR with the STARTUP_LOADER_OPTIMIZATION_MULTI_DOMAIN flag so that multiple documents don't require all of our assemblies for each document. We've also found through experimentation that loading a differently customized document (i.e. a new Word VSTO project) before loading our customized doc ...Show All

• SQL Server SetDefaultInitFields "TextBody" for Stored Procedure

  Following the suggestion in Michael Wories column, have found really nice performance optimization using SetDefaultInitFields (in my case, for the datatype parameter of columns). Tried to use SetDefaultInitFields for the "TextBody" parameter of Stored Procedures, and I get an error saying that "TextBody" is not a valid property for a StoredProcedure. Any thoughts on what might be the issue Thanks! Andy B I tried this and it works fine. Server server = new Server (); server.SetDefaultInitFields( typeof ( StoredProcedure ), "TextBody" ); I would t ...Show All

This is in the Requested By row in the Summary section. This name is not available to the build process. ...Show All

• SQL Server Textbox goes to new page and doesn't split across pages if height is too big

  I have a text box that contains a memo field.  It's located in the middle of the report page.  If the data is too big to fit on the bottom half of the report, then it goes to the next page.  This leaves a blank bottom half on the first / initial page.  How can I get the textbox to split across pages and not go to a new page automatically Thanks!

  In the following code sample, class TestClass { private int age; public int Age{ get {return age;} } } If I decide to use Age for the public property name, what is the recommended naming convention for the related private instance field Any comments are welcome. Microsoft does not provide naming conventions or guidelines for internal members, however, I have seen the following used internally: private int _Age; private int _age; private int m_age; private int m_Age; It is really comes down to a matter of choice and what you feel comfortable with. ...Show All
