Thread: Save vs Save As.... OPENFILENAME flags

Sometimes you don't need to Save As perhaps just wanna save to default/existing file..
My DoFileSave() function which saves data to a file looks as follows

Code:

// File save dialog
void DoFileSave(HWND hwnd)
{
	OPENFILENAME ofn;
	char szFileName[MAX_PATH] = "";

	ZeroMemory(&ofn, sizeof(ofn));

	ofn.lStructSize = sizeof(OPENFILENAME);
	ofn.hwndOwner = hwnd;
	ofn.lpstrFilter = "Binary Files (*.dat)\0*.dat\0All Files (*.*)\0*.*\0";
	ofn.lpstrFile = szFileName;
	ofn.nMaxFile = MAX_PATH;
	ofn.lpstrDefExt = "dat";
	ofn.Flags = OFN_EXPLORER | OFN_PATHMUSTEXIST | OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT;

	if(GetSaveFileName(&ofn))
	{
		WriteToFile(hwnd);
	}
}

What do i change in Flag (or this function) to prevent Save Save dialog box.. I'm adding both Save As & Save on the menu but do not know how to handle Save...
