Parameter	Description
hWndOwner	Handle of the window which owns the dialog.
pDlgParams	Pointer to a LINEREMOVEDLGPARAMS structure to be updated with the values entered by the user, through the dialog. Set members of this structure, before calling this function, to set the dialogs initial values.

Returns

SUCCESS_DLG_OK	The "OK" button was pressed, and the dialog exited successfully.
SUCCESS_DLG_CANCEL	The "Cancel" button was pressed, and the dialog exited successfully.

The L_LineRemoveBitmap function only works with 1-bit images. If you provide a bitmap in the LINEREMOVEDLGPARAMS structure, it must be a 1-bit bitmap.
