L_LTPDG_API L_INT L_PntDlgRegion(hWnd, pRegionDlgInfo)
Brings up the region properties dialog box.
Handle of the window that owns the dialog.
Pointer to a PAINTDLGREGIONINFO structure that contains region information. The values present in pRegionDlgInfo when the function is called are used to initialize the dialog, if PAINT_DLG_REGION_INITUSEDEFAULT is not set in the dwFlags member of pRegionDlgInfo. When this function returns, this parameter is updated with the values entered through the dialog.
| Value | Meaning |
|---|---|
| SUCCESS | The function was successful. |
| < 1 | An error occurred. Refer to Return Codes. |
