Kill process else run code how

[tom2]

i woud like my c++ code to run only if "myprocess.exe" is not running else if it is then terminate it and run the c++ code.

Is it necessary for you to search for the Process?

Is the Window Hidden of that Process?

If not then use FindWindow.

Code: [Select]

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

int main()
{
    HWND hwnd = FindWindow(NULL,"The Windows name");
    if(!hwnd)
        cout << "Could not find window!" << endl;
    else
        cout << "Found that Window!" << endl;
    cin.get();
return 0;
}
I remember working with Processes... it's a pain lol.

EDIT:
Depending on your compiler you might have to add something in front of the "The Windows name", eg

Code: [Select]

FindWindow(NULL,L"The Windows name");

EDIT2:
Checking the Process:

Code: [Select]

bool isRunning(string pName)
{
unsigned long aProcesses[1024], cbNeeded, cProcesses;
if(!EnumProcesses(aProcesses, sizeof(aProcesses), &cbNeeded))
return;

cProcesses = cbNeeded / sizeof(unsigned long);
for(unsigned int i = 0; i < cProcesses; i++)
{
if(aProcesses[i] == 0)
continue;

HANDLE hProcess = OpenProcess(PROCESS_QUERY_INFORMATION | PROCESS_VM_READ, 0, aProcesses[i]);
char buffer[50];
GetModuleBaseName(hProcess, 0, buffer, 50);
CloseHandle(hProcess);
if(pName == string(buffer))
return true;
}
return false;
}
It can be used like this:

Code: [Select]

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

bool isRunning(string pName)
{
unsigned long aProcesses[1024], cbNeeded, cProcesses;
if(!EnumProcesses(aProcesses, sizeof(aProcesses), &cbNeeded))
return;

cProcesses = cbNeeded / sizeof(unsigned long);
for(unsigned int i = 0; i < cProcesses; i++)
{
if(aProcesses[i] == 0)
continue;

HANDLE hProcess = OpenProcess(PROCESS_QUERY_INFORMATION | PROCESS_VM_READ, 0, aProcesses[i]);
char buffer[50];
GetModuleBaseName(hProcess, 0, buffer, 50);
CloseHandle(hProcess);
if(pName == string(buffer))
return true;
}
return false;
}

int main()
{
    if(isRunning("myprocess.exe")==true)
        cout << "w00t its running" << endl;
    else
        cout << "no its not...!" << endl;
    cin.get();
return 0;
}
I did not test them so do Post if you get a Compiler Error.

Posted on: March 08, 2010, 12:17:52 AMI have figured out if you put this at the end of the code then it will prevent it from running the code witch the c++ contain but the thing is i want it to not run if there is another program running.

Posted on: March 08, 2010, 12:56:45 AMwhat woud be similar to this:

begin
getself.hide
end.


but in c++
i tought of an idea but i need to know the code for that first what is it ?
Posted on: March 08, 2010, 03:24:02 AMit will work with a code that stop if found a certain form titlename, not windowname because this utility dont has a windowname (its hided from taskbar)

so if it can search for a form title name and then if that name is there then application will not start, but if it dont find it then it will.

woud this be possible atleast ?
