How to change to another Property Sheet and launch..

This might be blindingly easy, it's just new to me.

I have an application that is a single CPropertySheet containing several CPropertyPage instances.

void CScopePropSheet::AddControlPages()
{
      m_pSystemPage = new CSystemPage();
      m_pImagePage = new CImagePage();
//... etc

AddPage(m_pSystemPage );
AddPage(m_pImagePage );
// ...etc
}

Say the user is working within m_pImagePage. Clearly they could click the System tab and change to that tab. But I want to add a mechanism, whereby clicking a certain area in the image that is shown in Image Page, will force a transition to System Page, as well as call a method that m_pSystemPage implements.

(they could hit the System tab, and then click a button on the System page, but I need to essentially create a "shortcut" from the Image Page that will change pages and call initialization code in one click, under the hood)

All my click handling is in place, I just need to know how to make that page the active page (w/o the user having to hit the tab) and then execute a method within that page.

I hope that made sense :)

Thanks

Here is how you would go about it... Just call a public member function of CSystemPage and then call SetActivePage in the property sheet. Good luck -Aaron

// in class CSystemPage header file
public:
void DoSomething() { MessageBox("Do something");}

// in class CImagePage source file
void CImagePage::YouClickHandler(...)
{
((CScopePropSheet)GetParent())->m_pSystemPage->DoSomething();
((CScopePropSheet)GetParent())->SetActivePage(((CScopePropSheet)GetParent())->m_pSystemPage);
}

hmm.. I get these compile errors:

error C2440: 'type cast' : cannot convert from 'class CWnd *' to 'class CScopePropSheet'
error C2227: left of '->m_pScopePage' must point to class/struct/union

I can get basically the same thing to work, if I add a private member variable to my ImagePage of type CScopePropSheet, and then set it to "this" within the CScopePropSheeet after instantiating the ImagePage:

void CScopePropSheet::AddControlPages()
{
m_pImagePage = new CImagePage();
AddPage(m_pImagePage);
m_pImagePage->SetPropSheetParent(this); // accessor method I added to CImagePage to set private pointer to the prop sheet.

//..

}

then within my CImagePage

// your lines
// ((CScopePropSheet)GetParent())->m_pSystemPage->DoSomething();
// ((CScopePropSheet)GetParent())->SetActivePage(((CScopePropSheet)GetParent())->m_pSystemPage);

// my lines, which call upon my private pointer which now points to my parent
m_pScopePropSheet->m_pSystemPage->DoSomething();
m_pScopePropSheet->SetActivePage(m_pScopePropSheet->m_pSystemPage);

But while this is working, I don't like that I had to explicitly store a pointer to the parent property sheet.. I must be doing something wrong.

thoughts?

Thanks
