Error when upgrading t Toolkit Pro 24.0

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I have a MFC based Windows Application that compiles, builds and runs just fine with VS 2010 and Toolkit Pro 15.3.1. I am evaluating updating to Toolkit Pro 24.0.0 while also moving to VS 2019. I am able to get the code to compile and build just fine. However, I am getting the following error when setting the EnableMarkup() property on a CXTPRibbonBackstageButton object. This works just fine with Toolkit Pro15.3.1.
The error is 

---------------------------

Microsoft Visual C++ Runtime Library

---------------------------

Debug Assertion Failed!
Program: C:\**********\ToolkitProEval2400vc160D.dll

File: D:\Package\Temp\Eval\ToolkitPro\Source\Common\XTPApplication.cpp

Line: 103
Expression: NULL != m_pComInit
---------------------------
Any idea why this is happening?

	Please make sure that your main application class is derived from CXTPWinApp. Regards, Alexander

	Alex, Thanks for your prompt response. Sorry, I was out over the New Year's break hence couldn't reply earlier. That did address the original issue. However, I now get a more generic assert at runtime. This is an outcome of the latest change. Any idea what might be going on? --------------------------- Microsoft Visual C++ Runtime Library --------------------------- Debug Assertion Failed!
