CWindow::SetRedraw

void SetRedraw( BOOL bRedraw = TRUE );

Parameters

bRedraw

[in] Specifies the state of the redraw flag. If TRUE (the default value), the redraw flag is set; if FALSE, the flag is cleared.

Remarks

Sets or clears the redraw flag by sending a WM_SETREDRAW message to the window. Call SetRedraw to allow changes to be redrawn or to prevent changes from being redrawn.

Example

//The following example attaches an HWND to the CWindow object and 
//calls CWindow::SetRedraw() to set and reset the redraw flag

CWindow myWindow;
myWindow.Attach(hWndFoo);
myWindow.SetRedraw();      //sets the redraw flag to TRUE
...
...
myWindow.SetRedraw(FALSE); //sets the redraw flag to FALSE
