 Topic: Issue after upgrade of toolkitPosted: 29 January 2025 at 10:27am |

Hello,
I have an application which was used with Toolkit 13.4.0 without any known issues. Now I am linking the same source with the current version (24.0.0.0) and I get this error when the application is executed:  This happens when I access a specific tab of a CXTResizePropertyPage. So far, I couldn't make much sense of this. Can somebody please give a hint where to look? Thank you. |

Just some experiences I have had with COM and the new XTToolkit.
Some parts of XTToolKit uses COM objects; examples I found are the XML and Markup parser. For making it "simpler" for us XTToolkit included COM initialization to the CXTPWinApp class. However that can cause other problems. This means, that if you have something like AfxOleInit() or CoInitialize(NULL) in your CXTPWinApp InitInstance method you will also get an error. On the other hand if you don't derive from CXTPWinApp and uses some parts of the XTToolkit that uses COM you will get an error like the one you have. So try to change your CWinApp to CXTPWinApp and see if the problem is solved. |

Hello, thank your for the reply.
From what I see, the application derives from CXTPFrameWnd. -Ulrich |

I think that you have to go further back.
Try searching for CWinApp to get you to your application start object, and replace all occurrences with CXTPWinApp.
