Title: What is the "DoEvents" command?
Post by: SciTech02 on October 26, 2008, 04:09:34 PM

I have been reading some scripts written in MS Visual Basic and there is a command used that is called "DoEvents".  This seems to be a VB-specific command, since I can't find it in any other programing language.  What is this command and what does it do?  ???

very simple

it finishes doing all events that were called before the command and then goes on

lets say I do this code
Textbox.text = " hello world"  ' make text box say Hello World
Doevents
MMControl.Command = "play"    ' play a sound through MMcontrol component

In that case Doevents will not do next instruction until textbox.text was completed. This is a simple example, sometimes ( like in my VB code by my butler robot) there are more complicated things that need to be done in sequence.
