• Visual Studio Express Editions Combo Box Queries

  I have a couple of queries concerning the combo box, I'm undertaking a very ambitious project for a new comer to VB and have got a form with a number of combo boxes on there that will be used for setting up the serial port. I would like to know how firstly to get the first item to display in the combo box when the window is opened for example the list in one of the combo boxes is: COM1 COM2 COM3 etc. So when the form opens I want it to diplay COM1 not a blank drop down box. Secondly another box has a list of numbers however when displayed the numbers are not sequenced i.e. 1, 2, 3 etc. they actually display as 1, 10, 2, 3 etc. ...Show All

• Visual C++ "Correct" Workerthread Termination

  Hello, I have used worker threads for a long while and yet always had and still have problems with the "correct" way such threads should be killed for premature termination. They may have files open, are in the process of allocating global memory or doing any number of other things. The closest I got to "correct" is to signal the worker thread through it's priority if it's services are not required anymore for termination prior to it's full execution. Except the code then starts to look messy with CheckForKill()s all over the worker thread code. What is the "best correct" method to do this and yes, I am aw ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. DirectPlay

  I'm working on a messenger program, and someone suggested using DirectPlay. I've looked into it, and from what I can find, it looks like it could be very useful. Where can I find good documentation on how to use DirectPlay on both the client and server side of my application DirectPlay is deprecated and therefore not advisable to use for new applications. The reccomendation is to write your own stuff using the System.Net or System.Net.Sockets namespaces. If you really insist on DirectPlay the docs are in the archive on MSDN Managed DirectPlay Docs I can't find any C++ docs but they are probably ...Show All
