Thread: Error c2352 in MSVC6

Thanks for the advice but that does not work either.

I tryed both methods you suggested and I get the same error again.

If i try to call CWinApp:SetRegistryKey("SomeCompany")

I get

C2352: 'CWinApp::WriteProfileStringA' : illegal call of non-static member function

I think this problem is something to do with the base class CWinApp.

What I am trying to achive is when a user cancels the dialog box it writes some info to the registry.. It seemed to me that SetRegistryKey was only available in classes derived from CWinApp and that only one class can be dirived from CWinApp.


Because CUserinfo3App is dirived fro CWinApp this seems like the logical place to insert this function.. Thats were I am now..

I could just use the winapi reg funtions to do this but I am trying to get to grips with MFC.

If I have got the wrong end of the stick please let me know..

Thx

P..

Can you post the code showing the syntax you're using to call CUserinfo3App::WriteCancelled()?

void CUserinfo3Dlg::OnCancel()
{
CDialog::OnCancel();

CUserinfo3App::WriteCancelled(); // Caller
char CancelText[] = "You will be prompted to enter your account details again the next time you logon";
char CancelTitle[] = "FYI";
MessageBox( CancelText, CancelTitle, MB_OK | MB_ICONINFORMATION);

}

You need to refer back to nvoigt's response, you can't call non-static functions like that, and you can't make it static because it calls non-static functions.

You need to call it through your CUserinfo3App instance. Normally MFC automatically creates a global instance of your CWinApp derived class called theApp. So you'd call the functions like

theApp.WriteCancelled();

No joy with that, same error.. I'll tidy & zip up the project and will post here

Thanks for your time on this.


P..

Here it is. It contains the relevant code to show the problem.

THX

Thats it!!

I put the extern line in the dialog*.h file and its working.

I understood what you said about removing static before, but thought it best that I submit the project in its original form.

It was the second problem that was throwing me off. I would never have figured that one out.

Ta very much..
