I´ve made a CDialog based app where I have a PropertySheet om the main dialog. I have made 2 sheets and when I want to check the variables on both pages I run in to trouble. I can check the top sheet by calling.
No1.UpdateData(TRUE);
But if I do the same on No2 the prog crashes. How do I change the focus on the sheets so I also can use UpdateData on the 2:d sheet.
Thanx....

Where is the problem, if you call UpdateData() from your sheet, then you can Update all CPropertyPages:

Define two variables in your sheet.h-file:

CPropertyPage m_Page1;
CPropertyPage m_Page2;

and then in your sheet.cpp-file you can call:
m_Page1.UpdateData(TRUE);
m_Page2.UpdateData(FALSE);

and so on.

If you want to update page2 from page1 then it is a little bit complicated:

CPropertySheet *PointerAufPropertySheet=(CPropertySheet *)GetParent();
((CYourDialog *)PointerAufPropertySheet->GetParent())->DoWhatYouWant();

with proper casting the GetParent()-function you can reach every parent-class you wish.

Hope this helps,

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

If you are still in trouble with your code then send me your small dialog as .zip-file to mkuelsh@aol.com and I try to fix your error !! Because I have done the stuff with property sheets and pages a lot.

This is how I show the Sheet.
      PropertySheet.AddPage(&StartMenuDlg);
      PropertySheet.AddPage(&DesktopDlg);
If I make like you said the prog crashes. Don´t I have to make m_Page1 and m_Page2 point to the right sheets. How do I do that??

Next try:
I have too small information for solving your problem, try this:

if (m_YourSheet.GetActiveIndex()==0)
    m_Page1.UpdateData(FALSE);;
if (m_YourSheet.GetActiveIndex()==1)
    m_Page2.UpdateData(FALSE);

With calls of m_YourSheet.SetActiveIndex() you can also set one of the property pages active which you wish.

Maybe this works, I have too small information what you are exactly do !!!

Bye,
