C++ ShellExecute is not working the same way as cmd.exe

Question

I'm running this command

w_icrcom.exe j11 hola

from a command prompt and it is working properly, the exe is running using the arguments.

But when I'm doing the same from a C++ program the w_icrcom.exe is behaving differently. I'm getting an error saying that "abnormal program termination". This though is happening only when you pass arguments to 'w_icrcom.exe'.

It seems to me, that when I execute a command everything is fine, but when some other program is trying to execute the same command it doesn't work and I'm getting the "abnormal program execution" error.

I tried the same set up on ShellExecute calling the notepad.exe and passing arguments and it worked fine. Is there any logical explanation on this issue?

string test_var = ("j11 hola");
ShellExecute(0, "open", "C:\\Users\\PC\\Desktop\\My First\\connect\\bin\\w_icrcom.exe", test_var.c_str(), 0, SW_SHOW);

The next to last parameter of ShellExecuteA is the 'working directory'. It might need to be set to whatever is the current directory in the cmd prompt that is working. — David Ching, Mar 05 '15 at 13:59
I updated the issue with more info that I manage to test...I hope they will help you to find out what is wrong... — flowers for martians, Mar 11 '15 at 13:54
@michaelriis - you still haven't changed the next to last parameter of ShellExecute, which is the current directory. — David Ching, Mar 11 '15 at 15:53
@DavidChing - In one of the experiments I put "C:\\" because I thought it was the drive, and since you specify earlier the full path. But I just tried what you said, and now it is working great! Thank you very much! — flowers for martians, Mar 11 '15 at 16:22
