Here is my problem. I want to make a while() so my text flash every half second. Here is the code.

while(dbReturnKey() != 1)
{
dbCenterText(centerX, centerY, "Press ENTER to start...");
dbWait(500);
dbCLS();
dbWait(500);
}

It skips to the next part of my code when I press "ENTER", but when I press the Red "X" button to close the window it freezes and cannot get the program to close properly.

What I need to know is if there is a function for when you click on the "X".

For exemple : while(dbReturnKey() != 1 || !"FUNCTION FOR CLOSING THE WINDOW")

or

If you have another way of doing the flashing text thingy.

Thanks in advance!

Ok, so the series of commands you are using don't let the program respond to inputs while its "Waiting". So, I would recommend making a boolean var called textup that tells if the text is up or not. Then, wait like 30 refreshes (use a counting var to tell how many refreshes its been) and then reset the counter and invert the state of the text. So, if its up, take it down, if its down put it up(also record that you put it up or took it down for next time around).

You could also try:

while(dbReturnKey() != 1 && loopGDK()){
}

LoopGDK at the least checks for the ESCAPE key, but I wouldn't be surprised if it also checked for the windows close button and various other things. Give it a try.

Btw, DeadTomGC's advice about coding delays etc is a better way to code your loop. I'm just suggesting a possible quick fix without having to change your code.
