virtual L_INT LDialogFile::DoModalOpen(hWndOwner)
Displays the Open dialog box, and gets the options for LFile::Load.
Handle of the window which owns the dialog.
| Value | Meaning |
|---|---|
| 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. |
| < 1 | An error occurred. Refer to Return Codes. |
LDialogFile::SetOpenParams must be called before using this function to set the initial values for the dialog. You can get the updated OPENDLGPARAMS with the values entered by the user through the dialog by using LDialogFile::GetOpenParams.
