ITextHost::TxInvalidateRect

-description

Specifies a rectangle for the text host to add to the update region of the text host window.

-parameters

-param prc [in]

Type: LPCRECT

The invalid rectangle.

-param fMode [in]

Type: BOOL

Specifies whether the background within the update region is to be erased when the update region is processed. If this parameter is TRUE, the background is erased when the BeginPaint function is called. If this parameter is FALSE, the background remains unchanged.

-remarks

This function may be called while inactive; however, the host implementation is free to invalidate an area greater than the requested RECT.
