• Visual Studio 2008 (Pre-release) failed to print a range of pages using the PrintDialog

  Hi, I've been trying to print a range of pages from a flowdocument in a printdialog using the code below: Dim _pd As PrintDialog = New PrintDialog() If _pd.ShowDialog().Value Then _pd.PrintDocument(Directcast(flowdoc,IDocumentPaginatorSource).DocumentPaginator, _fileName) End If I am using the System.Windows.Controls.PrintDialog. I specified the page range in the dialog & the printqueue was Microsoft XPS Document Writer. All pages were printed out no matter what page range was specified in the dialog. Any idea if its a rtb flowdocument you might want do something like on this post http://blogs.msdn.com/llobo/archive/2007/01/24/printing-richtextbox-content-find-the-idle-printer ...Show All

• Visual Basic VB6 -> VS2002 -> VS2003 -> VS2005 -> nowhere fast!

  So, the upgrade from VB6 to VS2003 was really painful when it happened. A positive thing to note about it is that when you do that one you get big lists of errors and warnings and things that you need to change. If you then take that code and try to upgrade it to VS2005 you get NO warnings and NO errors and, dang it, a lot of things just don't work. It's very frustrating... Hi there, I'd really like to help you solve this issue, if you can send me a repro project then we can look into this to understand what's going wrong. You can email me at jonathan.aneja@microsoft.com . Thanks, Jonathan ...Show All

• Visual C++ C++ or Visual Basic for Windows Applications?

  I'm new to .NET, Visual Basic, Visual C++, etc. and I'm interested in creating Windows Applications. Which would be better to use, Visual Basic, or Visual C++ (And what about C# ) Thanks. I personally have just switched over to C++, and I have been using Visual Basic.NET for awhile, and I found it a lot easier to learn to program using Visual Basic, but I want more control now over how the program operates so I just switched a few days ago. But Visual Basic is much easier to both start with for learning and also for faster application development as far as I am concerned, unless there are more complex custom procedures required which in that case would be easier. But if you are planning to build window ...Show All

• Visual Basic VB.NET Parsing a variable - Left 3 digits and then the 7 last

  I am trying to take a variable that has a number. Lets say digits EX:1234567890 I need to grab the left most 3 digits (123) and the last 7 digits (4567890) and put it in a new variable with 2 spaces between. For the life of me I can not find out how to do so, I thought it use to be LEFT / MID RIGHT, but I am really a beginner to programming so I need some advice using vb.net language.

Any help would be appreciated Thanks You can still use the mid, left and right methods which are Basic methods, these are p ...Show All

• SQL Server FTP Task - Delete remote files always fails

  Hello, I have two FTP Tasks configured in my SSIS package. One is for "Receive files" and the other is set for "Delete remote files." Both use variables for the source/destination paths. My remote path variable contains a wild card in the name field such as /usr/this/is/my/path/*.ext and it is working to FTP all the .ext files to my working directory. I then rename the files and want to remove the original files from the FTP server. I use the same variable as the remote path variable in the delete as I do in the receive. Using the same FTP connection manager for both tasks I am always getting a failure on the delete. The FTP connection manger is setup to use the root user. Using a terminal I am able to open an ...Show All
