Problems with property sheets/property pages

[jonwil]

I have some code that creates a property sheet and some property pages:

class DialogBase
{
public:
HWND parent;
HWND dlg;
int dialogid;
static std::unordered_map<HWND, DialogBase *> map;
DialogBase(HWND Parent, int Id) : parent(Parent), dlg(nullptr), dialogid(Id)
{
}
virtual ~DialogBase()
{
map[dlg] = nullptr;
}
int ShowDialog();
virtual void OnInitDialog() = 0;
virtual void OnOk();
virtual void OnCancel();
virtual INT_PTR CALLBACK DlgProc(HWND hwndDlg, UINT uMsg, WPARAM wParam, LPARAM lParam);
static INT_PTR CALLBACK StaticDlgProc(HWND hwndDlg, UINT uMsg, WPARAM wParam, LPARAM lParam);
};

class PropertyPageBase : public DialogBase
{
public:
PropertyPageBase(int Id);
void OnInitDialog();
void GetPropSheetPage(PROPSHEETPAGE &page);
void SetModified(bool modified);
virtual bool OnApply();
virtual void OnReset();
void OnOk();

INT_PTR CALLBACK DlgProc(HWND hwndDlg, UINT uMsg, WPARAM wParam, LPARAM lParam);
static INT_PTR CALLBACK StaticPageDlgProc(HWND hwndDlg, UINT uMsg, WPARAM wParam, LPARAM lParam);
};

class PropertySheetBase
{
public:

StringClass title;
HWND owner;
HWND sheet;
WNDPROC oldproc;

return FALSE;
}

PropertyPageBase:ropertyPageBase(int Id) : DialogBase(nullptr, Id)
{

void PropertyPageBase::OnInitDialog()
{

I also turn on comctlv6 via this line elsewhere

#pragma comment(linker,"/manifestdependency:\"type='win32' name='Microsoft.Windows.Common-Controls' " "version='6.0.0.0' processorArchitecture='*' publicKeyToken='6595b64144ccf1df' language='*'\"")

I am on Windows 7 and am using the latest version of Visual C++ 2017 (15.9.2).

I have a derivative of PropertySheetBase and 3 derivatives of PropertyPageBase. In the PropertySheetBase derivative constructor I call Add_Page to add the 3 property pages to my sheet then later I call ShowDialog to actually display the property sheet and its pages.

However, only the first page is showing up, the other 2 tabs dont appear. Can anyone see anything wrong with my code in terms of how I use property sheets and property pages and anything I should do differently to make the other tabs appear? (it doesn't help that the MSDN documentation for property sheets and pages isn't exactly the best quality and some things are either not documented or not easy to find)

If you need to see the code that's actually using these classes, I can share the relavent components.
