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;
public:
virtual BOOL InitInstance();
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

No, just something you may not have thought of. The enum keyword is not like typedef in 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 to MODE to be _MODE instead. 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} ;
public:
virtual BOOL InitInstance();
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'

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.

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);

At the time the compiler encounters the MODE type, it does not know "who" it belongs to since the GetAppState() method is defined outside of the class declaration. So, you can either put the definition of the GetAppState() method inside of the class declaration, or you can qualify the MODE type by prefacing it with CBugReporterApp. 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.

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

I think you would be better served my adding three "status" methods to your CBugReporterApp class. 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?

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

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.

The 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;

Never 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.)

I'm going to patent thought. I have yet to see any prior art.

OK, thanks. I will put this in my notekeeper for future reference.

My version information is stored in MyProject.rc under the VS_VERSION_INFO . I also have a defined variable with the version info as its value that I use for an about section of the program. Is there a short way (maybe only a few lines of code) to set the File's Properties Version Tab to the value of that variable (i.e. change FILEVERSION and PRODUCTVERSION in VS_VERSION_INFO)? Basically so I don't have to go into the VS_VERSION_INFO and change it each time myself. So on build it reads the variable's value and changes the VS_VERSION_INFO automatically...

Something like this, perhaps?

No, I don't want it to actually auto increase the version numbers each time i build the executable. I simply want the key (ie FILEVERSION) to read the value of a variable within the code that I define; so I don't physically have to open up the resource file and change the key for the version in VS_VERSION_INFO. You follow what I mean?

That article wasn't meant to be a total solution to your problem. It was merely to show you what was invloved in operating on a project's .rc file.
Read the first section of this article.

I appreciate the help. I'll see what I can do with what I've read.

This belongs in your Init for your Help or About Dlg.
edit: the tabs didnt come out to well, but you can adjust!
<br />
CString szAllRights = _T( "All Rights Reserved." );<br />
CString szAppVersion;<br />
CString szComments;<br />
CString szCopyright;<br />
CString szCopyrightWarning;<br />
CString szCompanyName;<br />
CString szAppName = _T( "AppName.exe" );<br />
<br />
DWORD dwVerInfoSize;
DWORD dwVerHnd = 0;
<br />
dwVerInfoSize = GetFileVersionInfoSize( (WCHAR*)(const WCHAR*)szAppName, &dwVerHnd );<br />
<br />
if ( dwVerInfoSize )<br />
{<br />
HANDLE hMem;<br />
if ( ( hMem = GlobalAlloc( GMEM_MOVEABLE, dwVerInfoSize ) ) != NULL )<br />
{<br />
LPSTR lpstrVffInfo; <br />
lpstrVffInfo = (char *)GlobalLock( hMem );<br />
<br />
if ( GetFileVersionInfo( (WCHAR*)(const WCHAR*)szAppName, dwVerHnd, dwVerInfoSize, lpstrVffInfo ) )<br />
{<br />
LPWSTR lpVerInfo;
UINT lpVerInfoLen;
<br />
if ( VerQueryValue( (LPVOID)lpstrVffInfo,<br />
TEXT( "\\StringFileInfo\\040904B0\\FileVersion" ),<br />
(LPVOID*)&lpVerInfo,<br />
&lpVerInfoLen ) )<br />
{<br />
szAppVersion = _T( "Version ");<br />
szAppVersion += lpVerInfo;<br />
SendMessage( GetDlgItem( IDC_VER ), WM_SETTEXT, NULL, (LPARAM)szAppVersion.GetBuffer(MAX_PATH) );<br />
}<br />
else<br />
SendMessage( GetDlgItem( IDC_VER ), WM_SETTEXT, NULL, (LPARAM)_T("") );<br />
<br />
}<br />
}<br />
GlobalUnlock( hMem );<br />
GlobalFree( hMem );<br />
You need a IDC_VER in your dialog that you want to display that information into.
You can also get the strings from other parts of the versioning by using the following:
<br />
VerQueryValue( (LPVOID)lpstrVffInfo, <br />
TEXT( "\\StringFileInfo\\040904B0\\LegalCopyright" ),<br />
(LPVOID*)&lpVerInfo,<br />
&lpVerInfoLen ) <br />
<br />
VerQueryValue( (LPVOID)lpstrVffInfo,<br />
TEXT( "\\StringFileInfo\\040904B0\\CompanyName" ),<br />
(LPVOID*)&lpVerInfo,<br />
&lpVerInfoLen )<br />
Hope this helps

can someone tell me is there any code/program for erfc (complementary error function) in any of the Visual c++ header..especially the mathematical ones.
or any coding using this function..for my reference
thanx...

Hey people, I'm developing an application that gets SMS's from a GSM modem and uploads them to a DB. To do this i'm using a CInternetSession object. The app compiles OK but I get a Debug Assertation Error!. I think it has something to do with the internet session object because if I comment out anything to to with the CInternetSession then i don't get the debug error. Infact, simply the 'CInternetSession InternetSession;' declaration at the beginning causes the error alone.
