virtual L_INT LDialogWeb::DoModalJPEGWebTuner (hWndOwner)
Displays the JPEG Web Tuner dialog box, and gets the tuning options used by LBitmapBase::Save.
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_CLOSE | The "Close" 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. |
LDialogWeb::SetJPEGWebTunerParams must be called before using this function to set the initial values for the dialog. You can get the updated JPEGWEBTUNERDLGPARAMS with the values entered by the user through the dialog by using LDialogWeb::GetJPEGWebTunerParams.
