I have been trying to get the ShellAndWait routine written by Larry Rebich
located here
http://www.buygold.net/tips.html
to open a jpg file within a program, but I have not been able to get it to
work.

Passing the path of the jpg to CreateProcess returns the value of zero, but
the same path works in ShellExecute.

Is there anyway to get CreateProcess to open a jpg file or am I missing
something, which is usually the case. :-)

Thanks,
Norm

CreateProcess does just that. You'll need to pass the name of the executable you
want to start. As I recall, it also supports a command line, so if that app
supports passing a filename you'll be all set.

Karl,

I have tried this without success, where sCommand contains the path to the
jpg file
and I am not using any of the log functions. You might have to full screen
your reader
to see the full lines.

Public Function ShellAndWait(tShellAndWait As udtShellAndWait) As Boolean
' 1998/10/07 Add optional log and times
' 1998/10/27 Add DoEvents to allow the process to be terminated. Move
tProcess to caller.

Dim lMilliseconds As Long

Ah, well, ShellExecute isn't an executable. It's an API, just like CreateProcess.

ShellExecute Function ()
http://msdn.microsoft.com/en-us/library/bb762153(VS.85).aspx

In order to use CreateProcess, you'll have to tell it which process to create. The
utility of ShellExecute is that it does the registry lookup for you to find the
associated application for your datafile.

Boy talk about feeling like a dummy. :-) I guess it takes a while for this
to sink in.

Using IExplore.exe works just fine.

Thanks,
Norm
