Hi all,

When opening my application it needs to load quite a lot of images. I would like to show a progress form so I made a second form containing a progressbar and a label. When an image is loaded I update the label and the progressbar and then call Refresh() of the progress form, otherwise the label does not update correctly. This works fine, but when the progressform is moved, or another application is shown over the progressform (because it is maximized) and then minimized, the progressform does not update anymore.

How can I solve this?

kind regards,

Jef

HI

first off, are you doing this in an asynchroneous way? (you probably should be)

otherwise the gui will block will it's loading a file, which is probably not what you want

however, related to your problem:

try, instead of calling Refresh(), to call:
this.Invalidate()

Hope this helps, please close the thread if it does

I'm not doing it async. It is for personal use and I can do nothing with the app as long as images are not loaded.

I did try Invalidate() before, but that just makes it worse, the text doesn't refresh anymore. So I thought that was the wrong way.

Other ideas?

You could use a Backgroundworker control to do it async.

Your form won't do anything as long as it's loading the images. A possibility to refresh the form and receive user input at least from time to time would be to call Application.DoEvents() after having loaded an image.

Hi

can you post the code?

Application.DoEvents()

{load image 1}
Application.DoEvents();
{load image 2}
Application.DoEvents();
...

BackgroundWorker

• Add a BackgroundWorker to your form
• Handle the BackgroundWorker's DoWork event - here goes your code to load those images
• In Form_Load, start the BackgroundWorker - backgroundWorker.RunWorkerAsync()
