Rodd,
>> How do you use LoadPicture() in tandem with the image control? What property of the >> image control receives the return value of LOADPICTURE()?
I've just tried again, and LOADPICTURE works very nicely
= LOADPICTURE("C:\GoodPicture.bmp")
= LOADPICTURE("C:\BadPicture.Bmp")
= LOADPICTURE("C:\SillyTXT.txt")
LOADPICTURE returns a OLE Error when it tries to load the TXT or a corrupted image.
So, before assigning an image file to the Image object, use a TRY/CATCH with LOADPICTURE. and trap the error.
Worked perfectly here.
In HELP, you'll find "Creates an object reference for a bitmap, icon, or Windows meta file.", but you don't need that reference, so call LOADPICTURE directly... and enjoy !
So, you can try this way:
lcImageFile = GETPICT()
TRY
=LOADPICTURE(lcImageFile)
WAIT WINDOW 'IMAGE IS OK'
Thisform.Image1.Picture = lcImageFile
CATCH
WAIT WINDOW 'ERROR LOADING IMAGE !'
ENDTRY

>>>I'm trying to determine if the image that I assign to the Picture value of an image control is actually being displayed. In other words, if the user selects a corrupt image file to be displayed on the form in my image control, it won't be displayed. I want to be able to trap that and provide some feedback to the user so they don't think the form isn't working.

>>>As far as I can tell, the image control provides no feedback regarding invalid files ... it just doesn't display the picture. I'm already checking the extension and looking at the first 4 characters of the file to try to determine if they've selected a true image file. But none of this protects against corrupted image files.
