Is it possible to disable a MessageBox's button ??
Hello,
I am including a very important message box in my installer, and I would be sure that the user red the message before clicking "OK".
I configured the default button on "Cancel", but I think it's not enought.
The better would be to disable the "OK" button, sleep the installer during few seconds end then, enable it.
But I can't find how to access to the "OK" button of a messageBox with GetDlgItem, do you have an idea ?
Thank you very much
No one can say if it is possible or not ?
it might be possible..somehow, but NSIS code execution basically 'halts' as soon as the messagebox pops up - so there's no easy way to disable any button on it afterward.
some of the banner plugins might be what you need, or a custom dialog, or (Anders would know), maybe you can do what you need with the subclassing plugin.
to do this, you would probably need a hook + subclassing, see http://www.codeproject.com/KB/cpp/dMsgBox.aspx and to do this you probably need to write a plugin because I don't think the system plugin can do hooks.
Its probably possible to do this with just my subclass plugin by waiting for WM_ACTIVATE, but that would be a bit fragile if the user switched to another app just before your MessageBox
There is already a messagebox plugin, but I don't know if it supports a wait feature, but you might want to check that out first
