So i have a executable written in C++, and i wish to call this executable in Visual Basic, and be able to read results from running the C++ program.

The C program outputs its results in a text file when it's done running.

So my question is, how do I check, from Visual Basic for Applications, that the C program is done running?

thanks.

You have to use ShellandWait I think from advapi32.dll.

I would use Shell, get the process ID, and use OpenProcess with the SYNCHRONIZE flag set.

Then, with the handle obtained from OpenProcess, use WaitForSingleObject

So am I out of line in suggesting you simply throw a COM interface on the C++ program and load it from VB to get a rich programatic exchange?

Not at all, though some might argue the word "simply" is a bit misleading...
Syncronizing the processes like ^^^ they said up there is probably easiest.

Crud. I find VB one of the most annoying languages ever. What a lax grammar they build that language on.
I'd much rather C, C++, C#, Java, Lisp, JScript, Fortran...
