Starting a 16-bit process on Win95
Posted on 1998-09-03
I want to start a 16-bit process froma 32-bit application and then wait for that process to finish.
On NT it works perfectly as I am using CreateProcess with a CREATE_SEPARATE_WOW_VDM flag for process creation. However this flag is not valid on 95.
Followed by this I call WaitForSingleObject in order to wait for the 16-bit process to finish.
Now, if I dont ise CREATE_SEPARATE_WOW_VDM on NT this WaitForSingleObject returns immidiaely as the new process is spawned in 16-bit shared VDM.
So this problem is solved by CRAETE_SEPARATE_WOW_VDM on NT.
I will describe the scenario on win 95 in more detail.
1. I call CreateProcess to run a batch file (16-bit app)
2. This execution starts another process 'WINOLDAP'.
3. Even after all the execution in the batch file is complete this process does not shut down.
4. Because of this I do not get response for WaitForSingleObject which finally terminates on a time-out signal.
So how do I get rid of this WINOLDAP?
