pls help me to Get the caption of active window... ::GetActiveWindow()->GetWindowText(strCap); //ERROR error C2039: 'GetWindowTextA' : is not a member of 'HWND__' c:\program files\microsoft visual studio\vc98\include\windef.h(195) : see declaration of 'HWND__'

I don't know what exactly are you trying to do. But for the code you've posted I see the following: GetActiveWindow() return a HWND handle, there are not members functions to access from it. So, after saving your handle like this:
HWND hwnd = GetActiveWindow();Then you could call GetWindowText like this:GetWindowText(hwnd, strCap, sizeof(strCap))Demian.

Or he can combine them into one:
GetWindowText(GetActiveWindow(), strCap, sizeof(strcap));
That assumes that strcap is a definitive size. The last parameter may need to change if it happens to be a CString or strring or pointer to some buffer. Good luck.

see this, ::GetActiveWindow()->GetWindowText(strCap); //ERROR It looks like calling a member function using a class instance, possibly CWnd * (from GetActiveWindow), and :: makes the Global scope rather CWnd.

Oh yeah, of course.

yeap am using MFC, thank you all Friends... CWnd::GetActiveWindow()->GetWindowText(strCap); did the job

Probably he is (there's namespace scope specification). :)

It is redundant: if you don't need it, don't use it. :-D
