Anyone have some input on this? I'm trying to run a batch file using the WScript.Shell.Exec command. The issue I'm having is that the batch file writes a good amount of data to STDOUT/STDERR and it appears to be filling up its buffer and hanging. I've read somewhere that each invocation gets a 4K buffer for STDOUT/STDERR. This is the code that I'm using to read from the two streams. Is there a way for me to capture data from the stream so that it doesn't reach the 4k limit?

When I change the batch file to limit its output it runs without issue.

This is my code but it obviously needs to be modified.

Thanks in advance for you help and ideas.
