CBaseWindow::InitialiseWindow (Windows CE 5.0)

Send Feedback

Creates default device contexts for the window.

virtual InitialiseWindow(HWNDhwnd);

Parameters

  • hwnd
    Window handle.

Return Values

Returns an HRESULT value. Current implementation returns NOERROR.

Remarks

The base window class creates a window and a worker thread.

The worker thread is responsible for pulling messages from the window's input queue and dispatching them as appropriate.

The window and its thread are created by CBaseWindow::PrepareWindow and destroyed in CBaseWindow::DoneWithWindow.

The window should be initialized through CBaseWindow::InitialiseWindow and uninitialized through CBaseWindow::UninitialiseWindow.

Having prepared a window and initialized it, the window can be sized using CBaseWindow::ActivateWindow and subsequently hidden using CBaseWindow::InactivateWindow.

The base class creates two device contexts that can be used for drawing.

The first is a standard handle to a device context (HDC) for the window.

The second is an offscreen HDC.

The offscreen HDC often is useful for selecting bitmaps before calling the Win32 BitBlt or StretchBlt function to copy the bitmap to the main window.

This member function also sets the default stretch mode to be COLORONCOLOR.

The member function is virtual so derived classes can change this default if desired.

Requirements

DirectShow applications and DirectShow filters have different include file and link library requirements.

For more information, see Setting Up the Build Environment.

OS Versions: Windows CE 2.12 and later. Version 2.12 requires DXPAK 1.0 or later.
