[Starting with Windows Vista, the Open and Save As common dialog boxes have been superseded by the Common Item Dialog. We recommended that you use the Common Item Dialog API instead of these dialog boxes from the Common Dialog Box Library.]
An Open or Save As dialog box sends the SHAREVISTRING registered message to your hook procedure, OFNHookProc, if a sharing violation occurs for the selected file when the user clicks the OK button.
#define SHAREVISTRING TEXT("commdlg_ShareViolation")
This parameter is not used.
A pointer to a OPENFILENAME structure. The lpstrFile member of this structure contains the file name that caused the sharing violation.
The hook procedure must return one of the following values to indicate how the dialog box should handle the sharing violation.
||Accept the file name
||Reject the file name but do not warn the user. The application is responsible for displaying a warning message.
||Reject the file name and displays a warning message (the same result as if there were no hook procedure).
The hook procedure must specify the SHAREVISTRING constant in a call to the RegisterWindowMessage function to get the identifier for the message sent by the dialog box.
The dialog box sends the SHAREVISTRING registered message only if you did not specify the OFN_SHAREAWARE flag in the Flags member of the OPENFILENAME structure when you created the dialog.
If the hook procedure returns an undefined value, the dialog box responds as if OFN_SHAREWARN was returned.
