Добрый вечер!
Я пытаюсь создать второстепенное OpenGl окно внутри главного OpenGl окна, но возникает ошибка при регистрации этого окна. Код, конечно же, взят из уроков nehe.
Я так думаю нужно создать новые экземпляры этих классов. Также я создал WndProcTEX
Код:
HDC hDC=NULL, hDCTEX=NULL;
HGLRC hRC=NULL, hRCTEX=NULL;
HWND hWnd=NULL, hWndTEX=NULL;
HINSTANCE hInstance, hInstanceTEX;
Вот код создания второстепенного окна
Код:
BOOL CreateGLWindowTEX(char* title, int width, int height, int bits)
{
GLuint PixelFormat;
WNDCLASS wc;
DWORD dwExStyle;
DWORD dwStyle;
RECT WindowRect;
WindowRect.left=(long)0;
WindowRect.right=(long)width;
WindowRect.top=(long)0;
WindowRect.bottom=(long)height;
hInstanceTEX = GetModuleHandle(NULL);
//wc.cbSize = sizeof(WNDCLASSEX);
wc.style = CS_HREDRAW | CS_VREDRAW | CS_OWNDC;
wc.lpfnWndProc = (WNDPROC) WndProcTEX;
wc.cbClsExtra = 0; // No Extra Window Data
wc.cbWndExtra = 0; // No Extra Window Data
wc.hInstance = hInstanceTEX;
wc.hIcon = LoadIcon(hInstanceTEX, MAKEINTRESOURCE(IDI_ICON1)); //LoadIcon(NULL, IDC_APP_ICO);
wc.hCursor = LoadCursor(NULL, IDC_ARROW);
wc.hbrBackground = NULL;
wc.lpszMenuName = NULL;
wc.lpszClassName = "OpenGLTEX";
if (!RegisterClass(&wc))
{
MessageBox(hWndTEX,"Failed To Register The Window Class.","Ошибка",MB_OK|MB_ICONEXCLAMATION);
return FALSE;
}
и тут эта ошибка. Не пойму в чем проблема
на всякий случай код основного окна
Код:

{
GLuint PixelFormat;
INITCOMMONCONTROLSEX InitCommonControl;
WNDCLASS wc;
DWORD dwExStyle;

WindowRect.right=(long)width; // Set Right Value To Requested Width
WindowRect.top=(long)0; // Set Top Value To 0
WindowRect.bottom=(long)height; // Set Bottom Value To Requested Height
hInstance = GetModuleHandle(NULL);
//wc.cbSize = sizeof(WNDCLASSEX);
wc.style = CS_HREDRAW | CS_VREDRAW | CS_OWNDC | CS_DBLCLKS; // Redraw On Size, And Own DC For Window.
