This isn't the original program. The original has 8 tabbed pages. The
first tabbed page has 30 text boxes and 4 combo boxes on it. I just
wrote the test program with one label and one text box to illustrate the
problem -- which is: Even though the label overlaps the text box, on
his computer my brother can see the text box. On my computer, I can't
see the text box. That's the whole question. Why does he see the text
box and I don't? He accidently discovered that by setting the flag to
10 the label would appear in color and he could see that it was
overlapping the text box. He has since decreased the label lengths so
the text boxes are no longer covered up and has set the flag back to 0.
I have the very latest download of Winlib32. He tried the latest
version and had some problem so he went to the previous version. Maybe
that's why his works differently than mine.
As far as using SleText, I didn't know it had been replaced. Thanks for
telling me. I'll change the programs accordingly.
Pete, you're right. We are interested in writting something that will
work on different machines, including 1024 X 768 and 800 X 600
resolution.
