Hi, performers.

I have a question about getting the DC(device context) of
performer window(pfPipeWindow), which is created by the console program.

In case of using glut, the fragment of codes may be described as follows.
// glut
HWND hWnd = NULL;
HDC hDC = NULL;
hWnd = FindWindow(NULL, window_title);
hDC = GetDC(hWnd);

I tried a several method in console-based performer program like as...
1) call "wglGetCurrentDC()" in pfPipeWindow's configuration function
2) call "FindWindow->GetDC" in pfPipeWindow's configuration function
3) call "hWnd = (HWND)win->getWSDrawable();->GetDC(hWnd)" in pfPipeWindow's
configuration function
4) do 1), 2) after calling pfPipeWindow->open()

But, I failed in all cases, and didn't get right handles of window and DC;
i.e. still null values.
How can I get a DC of performer pfPipeWindow in console-based program ?
Is it not a sense to get a DC of visual pfPipeWindow in case of
console-based program,
instead of window based program ?

I want to use "WGL_NV_swap_group" extensions supported by Quadro 3000G for
frame synchorination. For this purposes, I indeed need the DC of performer
window.
In case of using glut, there is no problem, but I have no idea to solve this
problem in
performer; because I am pfRookie... ^.^;

Thanks in advance for any advise or hint about DC, Quadro 3000G.

Regards.
pfBye.
