First off, the IFileSaveDialog is an interface, not a simple function.
So, you'll need to:
- Include the right units from freepascal (ActiveX and comobj
IIRC)
- Initialize and finalize the COM subsystem (see CoInitialize
and CoUninitialize)
- Use the CoCreateInstance to instantiate an IFileSaveDialog,
etc.. I've never used the IFileSaveDialog myself, so have a
look at
https://msdn.microsoft.com/en-us/library/windows/desktop/bb776913%28v=vs.85%29.aspx#usage
That's the nice thing about the GetSaveFileNameA function: one call, and
you're done :-)
Now, if this function is not defined in the windows unit (which could be
the case), you can either look into some other units or simply define it
yourself:
=== code begin ===
Type
TOpenFileNameAHookProc = function(Wnd: HWND; Msg: UINT; wParam: WPARAM;
lParam: LPARAM): UINT stdcall;
TOpenFileNameA = Packed Record
lStructSize: DWord;
hWndOwner: HWND;
hInstance: HINST;
lpstrFilter: PChar;
lpstrCustomFilter: PChar;
nMaxCustFilter: DWord;
nFilterIndex: DWord;
lpstrFile: PChar;
nMaxFile: DWord;
lpstrFileTitle: PChar;
nMaxFileTitle: DWord;
lpstrInitialDir: PChar;
lpstrTitle: PChar;
Flags: DWord;
nFileOffset: Word;
nFileExtension: Word;
lpstrDefExt: PChar;
lCustData: LPARAM;
lpfnHook: TOpenFileNameAHookProc;
lpTemplateName: PChar;
lpEditInfo: Pointer; // Undocumented?
lpstrPrompt: PChar;
_Reserved1: Pointer;
_Reserved2: DWord;
FlagsEx: DWord;
End;
POpenFileNameA = ^TOpenFileNameA;
Function GetSaveFileNameA(arg: POpenFileNameA): windows.bool; stdcall;
external 'comdlg32' name 'GetSaveFileNameA';
=== code end ===
