error by creating process
- by Tyzak
hello i want to get startet with programming with WIN32, therefore i wrote a programm that creates a process but in the line of code where i create the process the programm gets an error an dosn't work (abend). i don't know if the code in programm 1 is wrong or the code in the second programm that should be created by the first. ( I don't know if the code in the first programm after "createprocess" is right because i didn't get further with debugging, because in this line i get the error.(i tested it without the cout,waitforobject and close handle but i didn't work either )).
First Programm:
#include <iostream>
#include <windows.h>
#include <string>
using namespace std;
void main()
{
bool ret;
bool retwait;
STARTUPINFO startupinfo;
GetStartupInfo (&startupinfo);
PROCESS_INFORMATION pro2info;
ret = CreateProcess(NULL, L"D:\\betriebssystemePRA1PRO2.exe", NULL, NULL, false, CREATE_NEW_CONSOLE, NULL,
NULL, &startupinfo, &pro2info);
cout<<"hProcess: "<<pro2info.hProcess<<endl;
cout<<"dwProcessId: "<<pro2info.dwProcessId <<endl;
retwait= WaitForSingleObject (pro2info.hProcess, 100);
retwait= WaitForSingleObject (pro2info.hProcess, 100);
CloseHandle (pro2info.hProcess);//prozesshandle schließen
retwait= WaitForSingleObject (pro2info.hProcess, 100);
ExitProcess(0);
}
Seconde Programm:
#include <iostream>
#include <windows.h>
#include <string>
using namespace std;
void main()
{
int b;
b=GetCurrentProcessId();
cout<<b<<endl;
cout<<"Druecken Sie Enter zum Beenden"<<endl;
cin.get();
//warten bis Benutzer bestätigt
Sleep (700);
ExitProcess(0);
cout<<"test";
}
Thanks in advance
