Re: Help: Not resolved external Symbol

Platform: Visual Studio .NET 2003

I read the MSDN and try using the Video for Windows. I have include
the file <VfW.h>.
Icalled the function capCreateCaptureWindow but failed.

I call the function like this:
// ----------------------------------------------
HWND GetWindow(int x, int y, int nWidth, int nHeight, HWND ParentHWND)
{
        HWND WindowHdl;

        WindowHdl = capCreateCaptureWindow(
                "Capture Window",
                WS_EX_CLIENTEDGE | WS_EX_LEFT | WS_VISIBLE | WS_EX_MDICHILD, //
Window Style. Defined in Help Topic: "CreateWindowEx Function"
                x,
                y,
                nWidth,
                nHeight,
                ParentHWND,
                1
                );

        return WindowHdl;}

// ----------------------------------------------

Compile message is:
----------------------------------------
Linking...
   Creating Library Debug/dll_study.lib and object Debug/dll_study.exp
dll_study.obj : error LNK2019: Not resolved external Symbol
_capCreateCaptureWindowA@32 $B!$(Bthis symbol is XXXed

HWND__ *)" (?

Debug/dll_study.dll : fatal error LNK1120: 1 unresolved external
Symbol
----------------------------------------

BTW, I don't use the VS of English Version, so the message is
translated into English but not origin.

I have totally no idea of where to start with, I don't even know what
"HWND__ * __cdecl GetWindow" is...
Where does the error come from and how can I solve it?

Thank you very much!
