PSN_KILLACTIVE
The PSN_KILLACTIVE notification message notifies a page that it is about to
lose the activation either because another page is being activated or the user
has chosen the OK button. This notification message is sent in the form of a WM_NOTIFY message.
PSN_KILLACTIVE
lpnmhdr = (NMHDR FAR *) lParam;
Parameters
lpnmhdr
Pointer to an NMHDR structure. The hwndFrom member is the handle to the property sheet.
Return Values
Returns TRUE to prevent the page from losing the activation or FALSE to allow
it.
Remarks
An application should validate the information that the user has typed.
To set the return value, the dialog box procedure for the page must use the SetWindowLong function with the DWL_MSGRESULT value, and the dialog box procedure must
return TRUE.
If the dialog box procedure sets DWL_MSGRESULT to TRUE, it should display a
message box to explain the problem to the user.

Nostalgia .Net |

.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
