Progress Bar Window Not Drawing

[bennett.sean@gmail.com]

Hi,

I've tried a number of different things including the use of threads
and timers, but can't come up with the solution yet.

The issue is this: launch a window with an animation or progress bar
that changes. While this "progress window" is being animated, launch
the actual window. Finally close the "progress window".

The problem is, the "progress window" does not render the gui until the
second window is done loading.

Any links or hints are appreciated.

Thanks,

Sean.

You need to add some Application.DoE vents calls into your load code for the
second window. All of this processing is occuring on a single thread of
execution. The timer events will not be received by the progress bar window
unless periodically you give up execution by calling Application.DoE vents.
Otherwise the only code that gets a chance to run is the code that is loading
your form.

DoEvents does do the trick... but the problem is that the code blocking
the message queue is in the InitializeCompo nent Sub of a form... so I
can't exactly put Application.DoE vents every 10 lines in
InitializeCompo nent.

There must be an easy solution. Help anyone?

Thanks,

Sean

Re: Progress Bar Window Not Drawing

I found out what was wrong.

Creating a thread was the right way to go but some additional
properties of that thread had to be set.

This is what made it work:

Dim t As System.Threadin g.Thread
t = New System.Threadin g.Thread(Addres sOf progressThreadS tart)
t.IsBackground = True
t.ApartmentStat e = Threading.Apart mentState.STA
t.Start()

the IsBackground and ApartmentState lines did the trick.
