• Windows Forms The order of files returned by the OpenFileDialog

  I have a question about the order of files returned by the OpenFileDialog. I have four files (File1.txt, File2.txt, File3.txt and File4.txt).  In the OpenFileDialog I select them in the order of: File1, File2, File3, File4.  However in the OpenFileDialog.FileNames array they are in the order File4, File1, File2, File3.  If I select them in the order File4, File3, File2, File1, then in the array they are in the correct order (File1, File2, File3, File4). Why, and is there any way they can be forced to be returned in the order selected, or at least alphabetical order I’m using VB .NET v7.1 and .NET Frame ...Show All

• .NET Development "Transport-level error" using .Net Beta2

  Hey, When I run the following code, I get the error: A transport-level error has occurred when sending the request to the server. (provider: TCP Provider, error: 0 - The specified network name is no longer available.) The code is: cnxn.Open() adptDeathMechanisms.Update(tblDeathMechanisms) adptCases.Update(tblCases) cnxn.Close() The error occurs when executing adptCases.Update(tblCases).  The connection is fine...that is proved by the fact that adptDeathMechanisms.Update executes just fine.  The connection is the same for both data adapters.  I don't know why the "specified network name" would suddenly be unavailable when exec ...Show All

• Visual C++ using a textbox from a 2nd Windows form
