Additionally, I do not want the newly created child process to spawn a window. I have seen the following examples, but I do not understand how to modify the code to accomplish what I am trying to do:.

The MSDN code appears to be written as two console apps, one calling the other. The code is confusing to me. It appears to reference a text file, which I don't need to do. The answer here was helpful, but over simplistic. I was hoping to see a basic source example one that doesn't involve hundreds of lines of complex code would be preferable.

I have tried using this from within my Windows Forms app, and while it compiles ok and doesn't cause any errors, it doesn't seem to work either. I have no idea why. It did not appear to do anything, except that on the first execution it give a very strange 3 characters as an output, then on subsequent executions, nothing. Basically, you want to fail with an error if the function ever does not return TRUE, and you want to keep looping until it yields a zero reDword.

EDIT: Since I was asked to provide some example code, here it is, though I have not gone through the trouble of actually compiling it to make sure it works, so please beware of syntax errors, and generally consider it only as a rough pointer to the direction in which it should be done:. Thanks to Hans Passant for the lead that got me to this clear and simple piece of code that does exactly what I was looking for.
