.NET Forum / Languages / Managed C++ / July 2005Error using Event Wizard "...parent class code is read only"
When attempt to use the Event Wizard I get the following error message: "Add/Remove of the function impossible, because the parent class code is read only" The Project was convert from VC 6.0. The files in question do not have the Read-Only Attribute on. Any Ideas? Hello John, We have reviewed this issue and are currently researching on it. We will update you ASAP. Thanks for your patience! regards, Rhett Gong [MSFT] Microsoft Online Partner Support Get Secure! - www.microsoft.com/security http://support.microsoft.com/default.aspx?scid=/servicedesks/msdn/nospam.asp &SD=msdn This posting is provided "AS IS" with no warranties and confers no rights. Hi John Based on my understanding, the problem is you could not use the event wizard to add a event handler to your MFC class which is converted from the VC6 program. Please let me know if I have misunderstood anything. In order to isolate your problem, would you please give us some more detailed information about this problem: 1. Have you used some source control system with this MFC project, such as the Visual Source Safe with the VStudio? 2. Is it a project-dependent issue--I mean if you have another VC6 MFC project and convert it to VC2003, does this problem occur? 3.Which class you this problem with, is it a MFC generic class(e.g. CButton) or a custom MFC class you derived? Thanks!

Hi Gary, Your basic understanding is correct. 1.. The project members are eventually saved in VSS. However, I don't feel this is part of the problem, since the problem does happen on a PC that is connected to VSS . 2.. I have not tried it on other projects, yet . See #3 3.. The class that fails is: cBaseFrame derived from CFrameWnd (class cBaseFrame : public CFrameWnd) 1.. I have been flipping back to VC 6.0 and using Class Wizard to insert the Event Functions framework (Menu Commands) 2.. If I specify a class derived from CWnd it works.. all is well Seems that a class derived from CframeWnd is the problem. Hope this helps..

Hi John, >1.. The project members are eventually saved in VSS. However, I don't >feel this is part of the problem, since the problem does happen on a PC that >is connected to VSS. Except the concern of the VSS, this problem could be caused by some related solution files being corrupted. In such scenario, you can try to delete(rename) your solution's .suo file and .ncb file, then reload the solution in the VS2003 IDE, the .suo file and .ncb file will be regenerated by the IDE. If the above workaround does not work, maybe you need to test your project in another machine in order to check whether this is a VS2003 IDE(machine) specific issue or a code deficit issue. If your project is OK in another test machine, then there may be some problems in the VS2003 of your current working machine, I suggest you can do a VS2003 reparation to it. Thanks!
