Error on opening/printing pdf using shellexecute

[neemi]

I am using the code below within a vba module to print a pdf document.

I have Adobe Reader 7 installed.

 lRet = apiShellExecute(hWndAccessApp, strOperation, _
            stFile, vbNullString, vbNullString, lShowHow)

where stFile is set to full path and file name of file to print
strOperation is set to "Print"
and lShowHow is set to WIN_NONE

However when I run the function I get an error do do with adobe reader. stating Adobe reader encountered a problem and needs to close. We are sorry for the inconveinience. etc etc

So I am presuming the code is working correctly but it just does not like adobe. I have reinstalled a fresh copy of Adobe in case there was a problem with it and it still occurs.

I know (or I think) the code works as it should as when I try to print a word doc using the function it does actually send it to the printer.

the full code is below which "opens" a file instead of "Printing" a file and the same error occurs with adobe only.

End Function

Has anyone else had this problem before?

Help appreacited.
Cheers,

Have you tried putting some wait code after the shellexecute call? A lot of things don't work well when they're spawned off of a process.

something like:

repeat
Process System Messages
Get Exit Code of Shell Process
until process is not active;

?

Only other thing I can think of is to try making sure your parms to the shellexecute call are correct.

all seemed to work when using acrobat reader version 5.0 and not 6.0 or 7.0.

strange but true. the same was with a lot of user pc's here.
