Waiting for external .exe to finish with open()?

jeffmarc

I use open to start a .exe utility that scans in a single image to a file. If I don't add a delay after the call, the program continues before the external scan is completed and the file is not written yet! Is there a way to monitor or know when the external process is done before allowing the program to continue?

Example:

String[] params = { "C:/Program Files/BarTender Suite/bartend.exe", "c:/stickers/stiker01.btw" };
Process p = Runtime.getRuntime().exec(params);

getting back to this. can u elaborate what params is. So this will execute the process and stop the draw loop from continuing until it is finished ?
