Shell VB App From C++ Code

[TupacShakur]

Hello,
I have an open source C++ command line tool of which I'm trying to manipulate the source code to modify its functionality for my personal use.
I have very limited knowledge of C++, and I need some help on how to synchronously shell another program (a VB app for that matter) with the initial argument line that was passed to the original C++ tool. The arguments parts is as troublesome as the "shelling" part because I'm not sure how to rebuild the arg. line from the argv[] array.

#include <stdio.h>
#include <stdlib.h>
#include <string>

int main(int argc, char **argv)
{
	FILE *proc;
	std::string command = "vbapp.exe";
	
	for(int i=1;i<argc;i++)
	{
		command += " " + argv[i];
	}
	
	if (proc = _popen(command.c_str(), "rt"))
	{
		while(fgetc(proc) != EOF);
		
		if (feof(proc))
		{
			return _pclose(proc);
		}
		else
		{
			return 1;
		}
	}
	else
	{
		return 1;
	}
}
