Intouch & Visual Basic

Hi all,

I am in need of some help. I am used to writing code in Intouch and now I find myself writing some VB code. For the most part its ok since it is event driven like Intouch. However, I have a need for some code to be scanned contantly...i.e. not event driven. Where do I put this code in VB. With intouch you just put it in the constantly scanned code with an update time of say 1000msec. How can I do the same in VB?

Something simple has never been so hard!!

Please help...

Rgds,

John

A VB program has a start-up Form or a start-up Module, you can see and change it in the "Project Properties"

You would have to write your own main program loop in that Module or Form (something Intouch does for you behind the scenes).

Use "Do...Loop" or similar instruction with loop exit conditions if necessary. Put your continuously executed code within the body of the loop.

Do not forget to include DoEvents() instruction somewhere within the body of the loop! Otherwise, neither your events would fire, nor you would be able to exit the program nicely.

If you care about having your code executed every X milliseconds, make a Form, put Timer control on it, and have your code executed from Timer control's Timer() event.

A Timer is the best way.


DoEvents() is a cpu hog. I use it only when I need to process lots of information in a loop and would need to break out if the user clicked a Cancel button to terminate it before it would normally end.

How often do you need to execute your code ?

Initialize your variables in you Main form / module and then set the Timer.Enabled = True (have it False upon startup) to get it going.

I agree with JustDaveIII. Use a timer event and set the time interval to the time interval you think you can get away with.
If the code you are running during the timer event takes a long
time then use DoEvents.

Thanks guys for the replies. I'll let you know how I get on.

Cheers.
