• Visual Basic StreamReader

  Hello, I’m trying to create a program will supply information for variables from a text file, so that as the possibilities change, a simple text file will need to be amended, rather than rewriting the original code. I am reading about FileStream and StreamReader, which seem like just the ticket. For instance, if I wanted to populate a TextBox with items I wrote in a text file, such as: Tom Mike Jim Jean I threw together a sub like this: ------------------------------ Private Sub Button6_Click( ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button6.Click Dim objF ...Show All

• Visual C++ CSocket Locks up in CSocket::ConnectHelper (sometimes)

  A CONNECT PROBLEM WITH CSocket I have what I think is some very simple CSocket code for a client and a server, but I'm having difficulty getting it working since it occasionally locks up. Any advice would be greatly appreciated. Here's the situation: I have a client program and a server program. I start them both up, assuring that the server starts up first and is waiting and ready for the client. They are both running on the SAME MACHINE. ON THE CLIENT SIDE When the client program is started it successfully makes a connection to the server, sends a simple (command) string to the server, and then retrieves (data) strings from the Server ...Show All

• Visual Basic Redundant DragDrop procedures for multiple textbox fields

  Using DragDrop text entry in textboxes is really cool, but is it necessary to have the following event handler for each and every textbox on a form Private Sub TextBox3_DragDrop( ByVal sender As Object , ByVal e As System.Windows.Forms.DragEventArgs) Handles TextBox3.DragDrop TextBox3.Text = e.Data.GetData(DataFormats.Text) End Sub Or can a less redundant programming reference be made to handle multiple textboxes where DragDrop is permitted Thanks!

• .NET Development Book recommendations?

  I just bought "Network Programming in .NET with C# and Visual Basic .NET" because of a recommendation here, but I got the book and found out that it's apparently in the wrong version for what I'm using. I'm using Visual Studio 2005 Professional, and I got syntax errors when I tried using some of the code in the book. The book looks like it's exactly what I want except for the incompatibility. Does anyone have any recommendations for books that teach socket and network programming in VB 2005 Thanks. Eventhough it is based on 1.1 version, the are very few changes at the socket level. You could work a ...Show All
