I'm an old C/C++ programmer so I apologize in advance if this questions is common knowledge to all the Visual Basic developers out there... I've gotten tripped up a few times when a variable was passed to a function/method by reference rather than by value. I've noticed that simple variables (integer, decimal, etc.) seem to be passed ...

Tight loop are an issue for a lot of languages because they don't give the PC enough time to process background jobs, this is the reason for commands like DoEvents() in Phrogram and VB, if you put a DoEvents in the tight loop usually this will solve the issue because it forces Background events to run. Thanks and have fun
