hi nimbu thomas.
The Documentation say's
LRESULT QuerySiblings(WPARAM wParam,LPARAM lParam);
and the snippet of code in MSDN
//====================================================================
// Validate the value entered in the Number edit control. If its
// value is not a natural number, request CPropertySheet (i.e. parent
// window of the page) to send a PSM_QUERYSIBLINGS message to each
// LOADED page (a page won't be loaded in memory until it is shown).
// If one of the pages returns a nonzero value in response to the
// PSM_QUERYSIBLINGS message, then inform the user and change the OK
// to Close and disable the Cancel button. CStylePage is a
// CPropertyPage-derived class.
BOOL CStylePage::OnKillActive()
{
int num = GetDlgItemInt(IDC_NUMOBJECTS);
if (num <= 0)
{
if (QuerySiblings(num, 0L))
{
AfxMessageBox("An invalid data is entered. Choose Close
button to close the dialog.");
CancelToClose();
}
}
return CPropertyPage::OnKillActive();
}
// This is an example of trapping the PSM_QUERYSIBLINGS in one of
// the pages. CColorPage is a CPropertyPage-derived class. Upon
// receiving this message, wParam contains the value passed to
// QuerySiblings() call. CColorPage will check this value and return
// FALSE only if the value is greater than 1.
BEGIN_MESSAGE_MAP(CColorPage, CPropertyPage)
// ...
ON_MESSAGE(PSM_QUERYSIBLINGS, OnQuerySiblings)
END_MESSAGE_MAP()
LRESULT CColorPage::OnQuerySiblings( WPARAM wParam, LPARAM lParam )
{
return (wParam <= 0);
}
//========================================================================
but CColorPage is a PropertySheet or PropertyPage getting Confused.
thanks and regards,
uday.

It's a property page. If it was a sheet they would have named it CColorSheet. Here it's a CPropertyPage derived class.

abc.Add("2");
abc.Add("3");
abc.Add("4");
abc.Add("5");
abc.Add("6");
abc.Add("7");
abc.Add("8");
QuerySiblings(1,(LPARAM)&abc); // Pass to the Third Page Values !!!!!
return CPropertyPage::OnKillActive();
}
//===========================================================================
third snippet of code
//===========================================================================
LRESULT three::OnQuerySiblings( WPARAM wParam, LPARAM lParam )
{
switch(wParam)
{
case 1:
CStringArray* pString = (CStringArray*)lParam;
for(int i =0;i< pString->GetSize()-1;i++){
str1.Add(pString->GetAt(i)); }
pString->RemoveAll();
break;
}
return 0;
}
BOOL three::OnSetActive()
{
for(int i =0;i< str1.GetSize()-1;i++)
{
MessageBox(str1.GetAt(i));
}
str1.RemoveAll();
return CPropertyPage::OnSetActive();

hi all,
i want to access the control values from one property sheet in another property sheet. (ie) if i am having three property pages and i want to get the control values of the first property page in second how can i achieve it. please provide the solution.
i am giving a snippet of code.
//==============================
CPropertySheet dlg(_T("Hellow"), this, 0);
one a;
two b;
three c;
dlg.AddPage(&a);
dlg.AddPage(&b);
dlg.AddPage(&c);
dlg.DoModal();
//=================================
where one,two,three are the the PropertyPages where each property page contains its controls, i want to access this values in different pages. please provide me a solution.
one solution is using global variable and set the values into globals but i dont want to use any global variables.
thanks and regards,
uday.

Use QuerySiblings.

Create a class/struct that represents all of the data for each of the pages. Create an instance of this class/struct in the property sheet. Each time a page is activated, it will query this class/struct to initialize the controls. Each time a page is deactivated, it will update the class/struct with the control values. Make sense?
