Syntax

#include "ltwrappr.h"

HWND hWndOwner

Handle of the window which owns the dialog.

Comments

LDialogDocument::SetHolePunchRemoveParams must be called before using this function to set the initial values for the dialog. You can get the updated HOLEPUNCHREMOVEDLGPARAMS with the values entered by the user through the dialog by using LDialogDocument::GetHolePunchRemoveParams.

The LBitmap::HolePunchRemove function only works with 1-bit images. If you provide a bitmap in the LDialogDocument class, it must be a 1-bit bitmap.
