I am usint the ShellExecute() function from the Win32 API. I followed David Frankenbach's excelent example and wrapper class. My problem is that I call the function to create a "pdf" file and then load that "pdf" into Acrobat for eMail. What is happening is that the program I use to create the "pdf" cannot create the file as Acrobat gains control of it before it can be created. In schematic format the code looks like this:

ShellExecute creatorpgm source destination.pdf
small code
small code
small code
ShellExecute destination.pdf - this calls the associated Acrobat

The ShellExecute function is not fininshing the first instanc before starting the second thus causing the conflict.

Can anyone give me a suggestion on how to get the thing to work sequentially.

Thanks in advance
Terry
