I have an application wich uses GetPage in the MainSheet initdialog and it worked before the latest VS 2008 updates and now it always returns null :(
CPage1* page1 = (CPage1*) this->GetPage(0); Is there any incompatibility between CJ toolkit and the latest VS 2008 updates ?

Hi,
Difficult to say without sample to debug. check what value returns GetPageCount(); ------------- Oleg, Support Team CODEJOCK SOFTWARE SOLUTIONS |

GetPageCount returns 8 because I have 8 pages, I call the GetPage function in OnInitDialog of the CXTPropertySheet
The code worked before the latest VS 2008 service pack, and now it returns a 0x000000 pointer

I have modified the TabManager sample so that you can see the problem in PropertiesDialog.cpp -> CPropertiesDialog::OnInitDialog()

Hello, It returns valid pointer for me. only window for this page is not created. Is it your case too ?
its actually feature of 13.1 release - we made it mork same as standard PropetySheet - Page now created only when user fuirst select it. It will increase perfomance when you have some Sheet with f.e 20 pages.
as solution you can call CreatePage(prop2); to be sure it is created now. ------------- Oleg, Support Team CODEJOCK SOFTWARE SOLUTIONS |

Hi,
I don't care about the window, but I have variables in each page which caused a crash when I called UpdateData(FALSE);
Now with CreatePage() works !!! thank you !
CPage2FileDisk* pageFileDisk=(CPage2FileDisk*) this->GetPage(1);pageFileDisk->m_bDelCustomFiles=theApp.GetProfileInt(_T( "Items"),_T("DelCustomFiles"),FALSE);pageFileDisk->UpdateData(FALSE); // This caused a crash
now if I add before a CreatePage it does not crash anymore  ------------- Product: Xtreme ToolkitPro 19.30 Platform: Windows 10 64bit Language: Visual C++ (VS 2019) |
