Sending string from console application to MFC

Question

Hi, Im invoking console application from my MFC application through ShellExecuteEx(). After the exe get loading,i want to receive one test string form console apllication to MFC,if i cannot receive the string then i will close both MFC and Console application.

For this,i want to send any string or valu from console application to MFC. I dont know how to do that.

char szFile[20]={0},szDir[500]={0}; 
memset(szFile,0,20);    
memset(szDir,0,500);    
strcpy(szFile,szModelName); 
strcat(szFile,".EXE");  
sInfo.lpFile = szFile;  
sInfo.hwnd = NULL;//this;   
sInfo.lpParameters ="MODEL";
strcat(szDir,"\\Sources\\");    
sInfo.lpDirectory = szDir;  
sInfo.fMask = SEE_MASK_NOCLOSEPROCESS;
sInfo.cbSize = sizeof(SHELLEXECUTEINFO);
sInfo.lpVerb = "open";
sInfo.nShow  =  SW_HIDE;
sInfo.hwnd   =  NULL;
BOOL bFlag = ShellExecuteEx(&sInfo);

Console application coding

int main( int argc , char *argv[] )
{   char str[50];   
strcpy(str,argv[1]);    
getch();        
}

If you want to send data from a console application back to the application that invoked it, you need to print to stdout and have the invoking application read that output. Don't use ShellExecuteEx, use a wrapper that deals with the file descriptor redirection that is necessary for you. Have a look at http://www.codeguru.com/Cpp/misc/misc/article.php/c321 . The CRedirect class in there does what you need.
