How to #define the path L”C:\Windows\System32\taskmgr.exe” for handling wide char

#define TASK_MGR "C:\\Windows\\System32\\taskmgr.exe"

KillProcess(TASK_MGR); //this works

HINSTANCE resurrect = ShellExecute(NULL, L"open", L"C:\\Windows\\System32\\taskmgr.exe", NULL, NULL, SW_MINIMIZE); 

Answer 1

Which version of Visual C++ are you using? This works on Visual Studio 2008:

#define PATH L"C:\\Windows\\System32\\taskmgr.exe";
void func()
{
    const wchar_t *test = PATH;
}

If, as Xeo commented, you want to widen the char array, use MultiByteToWideChar.
