I am making a program that categorizes pictures. The picture paths
are stored in an Access Database, vb6 connects using adodc controls.
This program works specifically with .jpg files. It will be used by
people categorizing thousands of images.
The problem I have is that both the picture control, and the image
control seem unable to open certain jpg images for an unknown reason.
The error message simply states "Invalid Picture". I can open these
problem picturesin MS Paint or any other photo editor and the images
works fine - the problem with the file seems to be limited to the vb6
controls.
Has anyone else had this problem?
I have made a duct tape solution by identifying what the native jpg
program is on the user's machine, but can't yet figure out how to run
that program and load the trouble picture into it. ie: if paint.exe
is the program associated to .jpg extensions, then open the problem
image's path in paint.
Does anyone know what the syntax/commands are to do such a thing?
Thanks!!

Just a wild shot...
There are different JPG format out, and VB6 isn't exactly new, so it
could be that some newer formats are not supported (you can see the
same problems with some old paint programs).
In this case you might try it using API functions, although I can't
tell you exactly how to do it.
The problem with your "duct tape solution" is that the Shell command
can only run executables, but cannot simulate a double-click on the
file. I know no solution for that, sorry.
Robert
not really no Trevor,
What you can do in VB is concatenate quotes..such as
SHELL "C:\Windows \
Shell "C:\windows\sys tem32\mspaint.e xe " & chr(34) & "c:\my picture.jpg" &
chr(34)
this should open it fine...it has for me

Thanks, Robert. I was working on my 'duct tape' solution last night
and found out that the following command:
Shell "C:\windows\sys tem32\mspaint.e xe c:\mypicture.jp g"
will load mypicture.jpg into MS Paint.
Unfortunately, this doesn't work if the path or file name of the jpg
have a space in it.
Shell "C:\windows\sys tem32\mspaint.e xe c:\my picture.jpg"
doesn't work because the program is looking for c:\my.bmp...
Shell "C:\windows\sys tem32\mspaint.e xe 'c:\my picture.jpg'"
doesn't work either although I don't know why. I have tried square
brackets, and parentheses, and nothing seems to work. Conversely,
c:\windows\syst em32\mspaint.ex e "c:\my picture.jpg"
will work when I go through the 'Run' Command of windows. For some
reason the single quotes don't cut it in this case, perhaps another
limitation of vb6...?
It worked exactly like it should! Thank you very much for your help.
