Have you used
/NODEFAULTLIBlinker option , by accident ?

Check

HWND curWin = FindWindow((LPCWSTR)winClass,(LPCWSTR)winTitle) - error !!! FindWindowW(wchar_t const *,wchar_t const *) - postfiks 'W' mean that the funktion use wchar_t instead char. And you can convert char* to wchar_t* by using _TEXT("") macros. And look here -> pHandle::setHandle(NULL) - wich of your function will be use?

Right click on your project and select property on the solution window go to linker of tree list on the left panel open it and select input and enter this file at Additional Dependencies.

Tks for your reply. I converted all char * to wchar_t const as same as definetion of function, but I still got that errors.
void pHandle::setHandle(wchar_t const *winClass, wchar_t const *winTitle)
{
HWND curWin = FindWindow(winClass,winTitle);
setHandle(curWin);
}Tks for your help
