Problem with enum
-
bdiamond wrote: I know it's something very stupid... No, just something you may not have thought of. The
enumkeyword is not liketypedefin that you also have to declare an actual variable of the new type before it can be used. So, just remove the_MODE MODE;statement, and change the three references toMODEto be_MODEinstead. Make sense?

I tried that first with just 'MODE' as the name of the enum like this:
class CBugReporterApp : public CWinApp { public: CBugReporterApp(); enum MODE {NEWMODE,EDITMODE,BROWSEMODE} ; // Overrides public: virtual BOOL InitInstance(); // Implementation afx_msg void OnAppAbout(); DECLARE_MESSAGE_MAP() void SetAppState(MODE enumState); MODE GetAppState(void); private: MODE m_enumState; };but I get this errormessage: error C2248: 'CBugReporterApp::GetAppState' : cannot access protected member declared in class 'CBugReporterApp' [insert witty comment here] bdiamond

I have an enum that I'm trying to declare in my App, that will be accessed by the other dialogs and such in the project. However I keep getting the following error message: error C2061: syntax error :identifier 'MODE' I've tried to do this before and ended up doing a workaround. I'd rather do it the right way and have never seemed to get the hang of it. Here's what I have in my class definition, with the line it specifies in bold:
class CBugReporterApp : public CWinApp { public: CBugReporterApp(); enum _MODE {NEWMODE,EDITMODE,BROWSEMODE} ; _MODE MODE; // Overrides public: virtual BOOL InitInstance(); // Implementation afx_msg void OnAppAbout(); DECLARE_MESSAGE_MAP() **void SetAppState(MODE enumState);** MODE GetAppState(void); private: MODE m_enumState; };I know it's something very stupid, but I can't figure out what I'm doing wrong. Any help would be appreciated. Thanks in advance [insert witty comment here] bdiamondThe problem is, as the code is currently written, MODE is a member variable of type _MODE. You are trying to use this member variable (MODE) instead of the type (_MODE) for parameters and other variables. Either change the functions to use _MODE instead of MODE or use a typedef like:
typedef _MODE MODE; -

error C2248: 'CBugReporterApp::GetAppState' : cannot access protected member declared in class 'CBugReporterApp' What line generates that error? That seems to be something else - this code fragment looks much closer to being correct than the first one you posted. An expert is somebody who learns more and more about less and less, until he knows absolutely everything about nothing.

You'll need to provide the relevant code for the
GetAppState()method.

in looking at the above message where I just declare the enum as 'MODE', here's what I have:
MODE CBugReporterApp::GetAppState(void) { return m_enumState; }and here's the line it's now crashing on in my UI handler for a menu button:
pCmdUI->Enable(theApp.GetAppState() == CBugReporterApp::BROWSEMODE);[insert witty comment here] bdiamond -

Even when I comment out the UI handler code I get the following errors:
error C2143: syntax error :missing ';'before 'CBugReporterApp::GetAppState' error C2556: 'int CBugReporterApp::GetAppState(void)' : overloaded function differs only by return type from 'CBugReporterApp::MODE CBugReporterApp::GetAppState(void)' error C2501: 'MODE' : missing storage-class or type specifiers error C2371: 'CBugReporterApp::GetAppState' : redefinition; different basic types[insert witty comment here] bdiamond

MODEtype, it does not know "who" it belongs to since theGetAppState()method is defined outside of the class declaration. So, you can either put the definition of theGetAppState()method inside of the class declaration, or you can qualify theMODEtype by prefacing it withCBugReporterApp. Make sense?

Yes, that makes sense and I changed it and it works for that problem. However I'm still getting this message for the UI update function that I showed earlier: error C2248: 'CBugReporterApp::GetAppState' : cannot access protected member declared in class 'CBugReporterApp' As you can see from my class definition, the function is declared as public, so what the heck is it talking about? I don't mean to be a nuisance, but I've gone too long making band-aids for certain problems or just getting something to work and not knowing why. [insert witty comment here] bdiamond

here's the function:
void CMainFrame::OnUpdateMaintenance(CCmdUI *pCmdUI) { pCmdUI->Enable(); pCmdUI->Enable(theApp.GetAppState() == theApp.BROWSEMODE); }I've also tried it with
int i = (int)theApp.GetAppState();and I still get the same error [insert witty comment here] bdiamond :zzz: -

CBugReporterAppclass. Something like:class CBugReporterApp : public CWinApp
{
public:
bool IsNewMode( void ) { return NEWMODE == m_enumState; }
bool IsEditMode( void ) { return EDITMODE == m_enumState; }
bool IsBrowseMode( void ) { return BROWSEMODE == m_enumState; }
};Does this help?

Your header file seems fine. I think the problem is in the implementation of your GetAppState(); (your cpp file). If you dont believe me, try commenting the source within GetAppState(). you wont get any errors. Try checking that function instead. Regards, Maha

Thanks in advance [insert witty comment here] bdiamondNever declare anything after using DECLARE_MESSAGE_MAP or DECLARE_DYN* (all the MFC macros) without resetting your access. They change the access setting of your class. Place a new "public:" prior to the definition of SetAppState and GetAppState. (Well, that and fixing the _MODE problem which you have already done.) Tim Smith I'm going to patent thought. I have yet to see any prior art.
