Hi,
I have an applicatin which when you click the print label button does the following:
1. creates an XML file
2. Uses the above XML file as an argument and invokes a 3rd party app "Dazzle"
3. "DAzzle" then prints out a postage label for USPS then
4. Creates an output xml file & stores in on the hard drive
5. Then with another button click we read the output file and append yet another XML file that will be sent via email to another location to update the original data with the tracking number and shipping cost.

It would be slick if I could eliminate the second button. But my attempts have failed.
When I try & put all of this under one event I cannot get my app to wait until the output file from Dazzle is created/updated before reading & appending the last file.
I'm am not familiar enough with threading & processes to solve this yet, any help would be appreciated... sorry for any spelling mistakes. Thanks
