Do not destroy the property sheet when clicking OK

[kshea]

Hi Everyone:

In a property sheet, when user clicked the OK button to exit the property sheet, I prompt a dialog to let user reenter the information in the notification message PSN_APPLY. After closed dialog, how can I keep the property sheet on instead of destroying it? (That is, acting like clicked Apply button)

Thanks in advance.

I guess you've overloaded the

OnOK()

function of the property sheet to make it launch the dialog? If so, then just don't call

Base_class::OnOK()

because this is where the sheet gets closed.
This call will be at the end of the function -

Base_class

might be

CDialog

or similar.

I find the solution. I did not use MFC anyway.

In the form of a WM_NOTIFY message, sent PSN_APPLY notification, Set the return value to PSNRET_INVALID_NOCHANGEPAGE or PSNRET_INVALID to indicate that the changes made to this page are invalid and the property sheet will not be destroyed. Otherwise, Set PSNRET_NOERROR to indicate changes made to this page are valid and have been applied.
