    You can use the Process32First/Process32Next functions.

    Thanks.

    Though I'm having some troubles. I have the below code up to now:

    Code:
    ......
    ......
    HANDLE hProcSnap = NULL;
    PROCESSENTRY32 pe32;
    MODULEENTRY32 me32;
    
    hProcSnap = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS,0);
    if(hProcSnap==INVALID_HANDLE_VALUE) ErrHandler();
    		
    pe32.dwSize=sizeof(PROCESSENTRY32);
    me32.dwSize=sizeof(MODULEENTRY32);
    
    if(Process32First(hProcSnap,&pe32))
    {
       do
       {
           Module32First(hProcSnap,&me32);
           strcpy(fpth,me32.szExePath);
       }while(Process32Next(hProcSnap,&pe32));
    }
    else
    {
       ErrHandler();
    }
    ......
    ......
    I'm trying to step through each process and get their module paths. But me32.szExePath returns nothing. please show me my fault.

    Thanks.

    Seems you need to create a snapshot for each process:
