Hello Everone ^^
i have a little problem
first the code is here
Code:
int main()
{
   DWORD processId = NULL;
   PROCESSENTRY32 pe32 = {sizeof(PROCESSENTRY32)};
   HANDLE hProcSnap;
   while(!processId)
   {
      cout << "Searching for " << ProcessName <<"..." <<endl;
      hProcSnap = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0);
      if(Process32First(hProcSnap, &pe32))
      {
         do
         {
         if(!strcmp(pe32.szExeFile, ProcessName))
            {
               processId = pe32.th32ProcessID;
               break;
            }
         }
         while(Process32Next(hProcSnap, &pe32));
      }
   }
   cout << "Found Process!" << endl << endl;
   CloseHandle(hProcSnap);
   return 0;
}

using console application the problem is i am set propety on Unicode and that cause a problem in this line if(!strcmp(pe32.szExeFile, ProcessName))
error there (pe32.szExeFile)
error info
    Error (active) argument of type "WCHAR *" is incompatible with parameter of type "const char *"
    Error C2664 'int strcmp(const char *,const char *)': cannot convert argument 1 from 'WCHAR [260]' to 'const char *'

to fix it need to change Property to Multi-Byte but can't do
that because others functions depend on Unicode so is there other way or fix for that to check the process is running or no ?!

Use the unicode version of strcmp. 'wcscmp'

Or use the TCHAR variants so things will compile in both unicode and multibyte. '_tcscmp'
