hello am trying to start another exe from my c program , am usign createprocess() but am getting error that , the commond is not recognized as internal or external
STARTUPINFO startupInfo = {0};
startupInfo.cb = sizeof(startupInfo);
PROCESS_INFORMATION processInformation;
CreateProcess(
bpath, // bpath is char and have C:\myf\myapp.exe
NULL,
NULL,
NULL,
FALSE,
NORMAL_PRIORITY_CLASS,
NULL,
NULL,
&startupInfo,
&processInformation
);
Is that a compile-time or run-time error? Did the program include windows.h? What compiler are you using?
bpath is char and have C:\myf\myapp.exe
If you mean bpath is a char-pointer try C:/myf/myapp.exe instead. The \ is an escape symbol but / is recognised as the directory delimiter under windows and *nix.
its run time error , i can't use / and / because i get windows dir using
char wdir[255];
GetWindowsDirectory(wdir,255);
so in wdir i get something like c:\windows\system32\
so start cmd i convert wdir to srting and then add \cmd.exe to that and convert again that string to char .
so in copy , move cases etc bpath works fine but in createprocess() it not works ????
On my computer GetWindowsDirectory() returns "c:\windows", not "c:\windows\system32\"; Check the output of GetWindowsDirectory() to see if it is returning what you think it is returning
#include "stdafx.h"
#include <Windows.h>
#include <iostream>
using std::cout;
int main(int argc, char* argv[])
{
char wdir[255] = {0};
GetWindowsDirectory(wdir,sizeof(wdir));
cout << wdir << '\n';
return 0;
}
