Form showing problem

[Dzemo]

I want to show some form with animated gif on it (Form1) while some data are
processed in background in application. I use

dim x as new Form1
x.show

for I=0 to 1000000
processing data
next I

x.close

This take about five minutes but form1 is not shown just rectangle without
picture. Do I have to refresh form ore something like that?
thx

Re: Form showing problem

Dzemo,

You can completly do this using the designer
You need only a picturebox
Set in the properties of that the image to a file
Ses in those properties as well that the sizemode as you want and
evertything else.

I hope this helps?

Either call 'Application.Do Events' every n-th iteration, or use
multithreading (this means, you put the data processing in a separate
background thread):
