• Visual Basic Visual Basic and graphics - for the novice/beginner

  Hi there I have no training in programming, but would like to start writing my own little programmes. In my work (civil engineer), I am increasingly frustrated by the lack of simple, time saving programmes to make my life easier, and hence the urge to write my own programmes. Of course, the start will be no more than programmes for one-off formulas, but having said that, I would like to (in many year's time) be able to write more complicated programmes. And of course what I have in mind involves graphics, specifically being able to draw (for instance) pipelines (with coordinates) and then be able to generate a longitudinal section from th ...Show All

• Visual Basic Form Design Goes Blank when switching between code and design?

  Hi, I am running the release version of VS 2005 Professional.  I have noticed a really annoying problem.  I am developing a SDI application using a tab control to provide access to multiple pages that allow the user to input data.

I often switch back and forth between the code window and the design window and most times I do this the design window goes white and the cursor is not busy but there is a delay of about 15 or 20 seconds before the design win ...Show All

Is there any way to have all associations shown automatically Wow this is awesome, just what I was looking for. Thanks very much. ...Show All

As I no longer have access to VFP6 and the table needed updating, I tried to test out VFP9 with this project.
