L_LTDLG_API L_INT L_DlgSave(hWndOwner, pOpenFileName, pDlgParams)

L_HWND hWndOwner;

/* owner of dialog */

LPOPENFILENAMEW pOpenFileName;

/* pointer to a Windows OPENFILENAMEW structure */

LPSAVEDLGPARAMS pDlgParams;

/* pointer to a structure */

Displays the Save dialog box, and gets the options for L_DlgSave.

Parameter

Description

hWndOwner

Handle of the window, which owns the dialog.

pOpenFileName

Windows structure. This structure is documented in the Microsoft Windows SDK documentation. For this function, you must set the following members of the OPENFILENAMEW structure:

 

lStructSize

 

lpstrFilter

 

nFilterIndex

 

lpstrFile

 

nMaxFile

 

lpstrFileTitle

 

nMaxFileTitle

 

lpstrInitialDir

 

lpstrTitle

 

lpstrDefExt

 

 

 

Flags

 

LEADTOOLS specifically sets the following flags:

 

OFN_HIDEREADONLY

OFN_ENABLETEMPLATE

 

OFN_ALLOWMULTISELECT is not set by LEADTOOLS automatically, but is allowed.

 

OFN_SHOWHELP is set only if you specify a HELP callback (that is pfnCallback was not NULL).
