  12. Use of Runtime Data Source with Visual Report Writer

  14. A Folder Selector With Initial Folder Setting

    This week two developers asked me about a folderbrowser/selector. Over the years several solutions have been created (fully) using the Windows API. But as far as I know they all do not have the ability to set the focus on a certain folder shown in the tree. And that is what the developers wanted to have. I said it is "simple" to make a folder selector yourself. This blog tells you how you can create one yourself using Visual DataFlex code and a bit Windows API code.

  16. How to change the internet connection timeout

    When your Visual DataFlex application makes an external call to a webservice the main program waits for its completion. If the request does not return immediately several things can be the cause. Your connection to your ISP can slow, the webserver you try to reach is busy, can be difficult found etc. If you want your application to continue as soon as possible and know (and this is they unknown keyfactor) that particular call should not take more than a couple of milliseconds to complete you can ...
  17. Programmatically find out if UAC is turned ON
