Still not working

[Anon777]

Hello everyvone I was used createprocess () function to run a processes on my OS (windows). Here is my source:

#include <iostream>
#include <windows.h>
using namespace std;
int main(int argc, char *argv [])
{
    //declaration for first process
    PROCESS_INFORMATION pi;
    STARTUPINFO info;
    memset(&pi, 0, sizeof pi);
    memset(&info, 0, sizeof info);
    info.cb = sizeof STARTUPINFO;
    info.dwFlags = STARTF_USESHOWWINDOW;
    info.wShowWindow = SW_SHOWNORMAL;
    //declaration for second process
    PROCESS_INFORMATION pi2;
    STARTUPINFO info2;
    memset(&pi2, 0, sizeof pi2);
    memset(&info2, 0, sizeof info2);
    info2.cb = sizeof STARTUPINFO;
    info.dwFlags = STARTF_USESHOWWINDOW;
    info.wShowWindow = SW_SHOWNORMAL;
    int choose;
    char er; //exit or restart a program 
    replay:
    cout << "Which program vish run - 1/2?" << endl;
    cin >> choose;
    if (choose==1)
    { 
        CreateProcess(NULL,                     //run first program
        "d:C:\Folder1\\Folder2\\program1.exe", 
        NULL,
        NULL,
        FALSE,
        0,
        NULL,
        NULL,
        &info,
        &pi);
    }
    if (choose==2)
    {
        CreateProcess(NULL,                     //run second program 
        "d:C:\\Folder3\\Folder4\\program2", 
        NULL,
        NULL,
        FALSE,
        0,
        NULL,
        NULL,
        &info,
        &pi);
    }
    else 
    {
        while (1)
        {
            cout << "Wrong number!" << endl; 
            cout << "Waiting 5 seconds:" << endl;
            for (int wrong=5; wrong > 0; wrong--)
            {
                cout << wrong;
                Sleep (1000);
            }
            goto replay;
        }
    }
    cout  << "Press Q - quit program" << endl; 
    cin >> er;
    if ((er=='Q')||(er=='q'))
    {
        for (int bay=5; bay > 0; bay--)
            {
                cout << bay;
                Sleep (1000);
            }
    }
    else 
    {
        cout << "Error!!!" << endl;
        Sleep (2000);
        return -1;
    }
    return 0;
} 

But there are two errors and one warning:
11: expected primary-expression before ';' token
19: expected primary-expression before ';' token
30:9: [Warning] unknown escape sequence '\F'

Can anyone tell me true code of 11,19 and 30 lines?

And I wish to close this two process leter in this program. But I don´t wish to use Terminate Process (); becouse this function finish program very unclean! I think that Terminate Process (); leave DLLs open. Please fix me if I distrub in this think.

If you can please tell me yet how:
I reached switching betwen this two programs (If one running process start closing automatically run another AND if I start process - craateprocess () automatically close another program)
how can I got more properties about running proceses (Size of program, how much demanding is my running process for my PC or what similar)

Tnx for all post, Anon 777

I can't help you with the WinAPI related problems, but your syntactic errors are:
line 11 and 19: the sizeof operator needs parenthesis around it's operand : sizeof(something);
line 30: you meant "d:C:\\Folder1\\Folder2\\program1.exe"

[Anon777]

sizeof(something);

- >this helps problem with source code which is up is saved. -> tnx ROmai
And I discovered mastake of 30 line: "d:C:\\Folder1\\Folder2\\program1.exe" I was written this line witout d:
And I was discovered one big mastake which my compilker did not:

 else 
    {
        while (1)
        {
            cout << "Wrong number!" << endl; 
            cout << "Waiting 5 seconds:" << endl;
            for (int wrong=5; wrong > 0; wrong--)
            {
                cout << wrong;
                Sleep (1000);
            }
            goto replay;
        }
    }

must be if I wish that program working true:

 if ((choose!=1)&&(choose != 2)) 
    {
        while (1)
        {
            cout << "Wrong number!" << endl; 
            cout << "Waiting 5 seconds:" << endl;
            for (int wrong=5; wrong > 0; wrong--)
            {
                cout << wrong;
                Sleep (1000);
            }
            goto replay;
        }
    }

I also can use switch instead of if in this example!
This errors are saved now can anyone answer on this questions:

And I wish to close this two process leter in this program. But I don´t wish to use Terminate Process (); becouse this function finish program very unclean! I think that Terminate Process (); leave DLLs open. Please fix me if I distrub in this think.

Tnx for all next replies and again thank you Romai!

The following demonstrates how you can stop a program (supposing it's a windows application) started with CreateProcess, by sending a WM_CLOSE message to each window of its main execution thread.

#include <iostream>
#include <string>
#include <windows.h>
using namespace std;

BOOL CALLBACK CloseThatWindowPlease(HWND hwnd,LPARAM lParam)
{
    SendMessage(hwnd,WM_CLOSE,0,0);
    return TRUE;
}

int main()
{
    PROCESS_INFORMATION pi;
    STARTUPINFO si;

    memset(&pi, 0, sizeof(pi));
    memset(&si, 0, sizeof(si));

    si.cb = sizeof(STARTUPINFO);
    si.dwFlags = STARTF_USESHOWWINDOW;
    si.wShowWindow = SW_SHOWNORMAL;

    string program_name;
    cout << "enter the program name:\n";
    getline(cin,program_name);

    CreateProcess(program_name.c_str(),NULL,
        NULL,NULL,FALSE,0,NULL,NULL,&si,&pi);

    cout << "\nhit enter to close the process and quit";
    cin.get();

    EnumThreadWindows(pi.dwThreadId,CloseThatWindowPlease,0);

    //Don't forget these... I did in the original post...
    CloseHandle( pi.hProcess );
    CloseHandle( pi.hThread );

    return 0;
}

tnx it helps me but not in whole becouse it must start another program AUTOMATICALLY when one of this two start closing by user. And when It run and I run anoter program start closing
the first one
I was trying but It was not work!
I know somthing what I need function wich we call CALLBACK becouse this function allowing communication bettwen OS and my program

and I also need a switch...

MSG message;
switch (&message)
{
case WM_CLOSE: //must controling only a window of specific program
CreateProcess(program_name.c_str(),NULL,
        NULL,NULL,FALSE,0,NULL,NULL,&si,&pi);
} 
break;

and ...

MSG message;
switch (&message)
{
case WM_ACTIVATE: //must controling only a window of specific program
SendMessage(hwnd,WM_CLOSE,0,0); // send message to specific program 

} 
break;
