• Visual Studio Express Editions What books to get

  I have looked at the local book store for books on programming. There seems to be a selection of books on VB6 and also on VB.Net. Which would be a better choice for me to get in order to learn the Express edition Any major differences I should know about when reading one of those that I need to keep in mind when I'm applying it to VB Express Thanks! Whatever book(s) you get, get those that cover VB2005. The other versions, won't help you with VB2005. There are a lot of new books for VB2005 and even some that include a copy of VB2005 Express Edition. I haven't used but one book on VB2005 and that was Introdu ...Show All

• SQL Server Solution Explorer and SQL Server

  I am a Visual Studio .net developer and understand Solutions and Projects in VS.net.  Nevertheless, it appears that the paradigm of using Solutions Explorer in SQL Server is not exactly the same.  That is, in Visual Studio you can't get anything done without creating a solution first.  In SQL Server, it is entirely possible to get a lot done without a solution and the ability to create and make use of a solution seems almost an after thought or an add-on. I am particularly interested in using a solution in SQL Server to allow me to make use of SourceSafe.  In the past, we jumped through all kinds of hoops to keep a runni ...Show All

• Visual Studio Team System Visual Studio 2005 Professional

  Will Visual Studio 2005 Professional be able to access Team Foundation Source Control directly or will we have to use the TFS 'explorer' to do Get/Check out/Check in etc I seem to remember reading that Professional would be able to directly access TFS Source Control but this page http://lab.msdn.microsoft.com/vs2005/productinfo/productline/default.aspx  seems to contradict that (and I can't remember where I read what I think I read) One thing to consider is that SourceSafe is included in the MSDN Premium subscription.  Does this help address your need ...Show All

• Windows Forms DataViewGrid bug? (keeps auto-generating columns)

  When we use the grid, it auto-generates columns for us. At first I thought that was handy. We removed some columns, but they are again re-generated automatically. ITEM TWO We also noticed that the order of the columns is not the same at run time as it is at design time. Note: I am using VSTS Beta 3. Beat regards, Jerry Nixon You need to set the AutoGenerateColumns Property to false to prevent the columns from being generated automatically like so: grdCategories.AutoGenerateColumns = false ; categoryCollectionBindingSource.DataSource = CategoryFactory .GetAllCategories(); ...Show All
