I have a several large images that take anywhere from 10 to 25 seconds to load on to a form. I would like to have a progress bar appear and do its thing to show the progress of the image thats being loaded while the images is loading.  Any ideas?

Unfortunately, you can't. LoadPicture is a built-in function for the picture box, image box and forms. Once it is entered,  control will not return to VB until it is completed.

Of course, since you load multiple pictures, you can just show a progress bar that indicates an approximate value. Example:

Picture1.Picture = LoadPicture(...)
ProgressBar1.Value=20

Picture2.Picture = LoadPicture(...)
ProgressBar1.Value=50
....
....
etc.

Something like that...

The only "trick" is to show a "loading" animation (animated gif) when loading a picture...


Cheers!

If these images are loading onto your main form, then use a splash screen with a timer that lasts the approximate time of the image load (This load time will vary according to processor speed).

If these images appear on a subsequent form, then call the form to load when the main form loads.

Sub Form1_Load()
load frmSlowForm
End Sub

Then when you want to display the form ...

just use frmSlowForm.Show

Don't unload the form until your done with it or it will make you wait again.

Screen.MousePointer = vbHourglass
    Picture1.Picture = LoadPicture("...")
    Screen.MousePointer = vbDefault
