Waiting Form

[John]

Try to implement an waiting form, which has a label and a
textbox, as below:

FormWait fm = new FormWait();
fm.Show();
for (long i = 0; i < 20000000; i++)
{
// some lengthy operations
}
fm.Close();

The texts of the label and the textbox won't display until
the for loop ends. How can I make them display from the
begining?

Thanks

John

put a doevents in the loop. This will keep it from appearing to lock up as
well.
