don't give up so fast ...
remove the line
m_strMessage = "Place a message here";
m_bShowMsg = TRUE;
m_bShowPgm = TRUE;
m_bEnableMessage = TRUE;
m_bEnablePgm = TRUE;
UpdateData(FALSE);
and if there are compilation errors, fix them, go line by line and compare; in the visual studio IDE you can double-click on an error line in the output window and it will go to the line in the editor.
If you think there are no errors in the .cpp file, check the .h file; and don't give up so easily.

This is fair enough, but I am only going off a book which fails to tell users that they will get 27 errors.
Whoever wrote the book "gave up" it seems.
Glad I didnt have to pay for the book or program, I will try borland.
Thanks for all your help with this, I dont know how you keep your sanity doing this 
Not going off the guide is one thing but I am lost now, totally lost.

you will still fail if you don't take the time to learn how to fix compilation errors.

who said the errors were in the book; check again, post the 27 errors, or the first few and the relevant code lines, we could help.

From the looks of it, the variables weren't declared within the class. If you're not using ClassWizard to generate the handlers, then you may want to check for the following them in the header file.
Inside the class definition, make sure there are declarations for five variables, something like the following:
CString m_strMessage;
BOOL m_bShowMsg;
BOOL m_bShowPgm;
BOOL m_bEnableMessage;
BOOL m_bEnablePgm;
Honestly, C++ isn't a good "trainer" language. Have you programmed in any other languages before?

27 errors doesn't mean that you have made 27 errors, it means that the compiler found 27 erros, but some errors are caused by only one (other) error. It could be that if you change 1 character most errors are already solved...
good luck.

Thanks for all the help, being a beginner, I have only done a little HTML coding and tiny bit of Java.
I know that of all the languages to learn first, C++ is not a good choice! Its very complicated I know but this is whay I want to learn it.
"in the visual studio IDE you can double-click on an error line in the output window and it will go to the line in the editor."
I didnt know this, and this info is greatly appreciated, it will halp a lot to find these errors.
I thought myself it probably is like a "domino effect" with probably a few errors triggering off many others.
What I dont like about Visual C++ is that it refuses to compile if there ar errors. You should have the option still to build it as another name or something, just so you could maybe work out whats wrong by using the program you compiled to see what happens (or does not happen which would be more like it!)
I always say im giving up but I never do! I moan a lot when it goes wrong so quickly into this book but heh, IMHO the very best way to learn something is to fail at it! Sound silly but you "learn" better, because you feel bad failing and dont wanna feel bad again and it sort of makes you snap. If you went through life never failing I am sure your brain would turn to mush (senile) early on in life!
Still not tried my code with BOOL in front. I did use the class wizard to put the function names on my buttons, name the buttons etc, so I guess this BOOL isnt needed?
Still not tried it the other way, its posted here leaving a line out, will try this in a minute.
Anyone wanting to see my code - its in my older posts here, the one with 27 errors and no warnings (and me moaning a lot!).

Honestly, I don't think these kind of books are good for learning C++. They will learn you how to use the MFC and class Wizard and things like that (in fact how to work with the Visual C++ IDE). It should be named 'Learn to use MFC in 21 days' instead of 'Learn C++'.
But in fact this is not a good way to learn C++. For me, I think the best method is working simply with console applications to learn really the basics of C++ (the syntax, the rules, classes, ...). And once you are familiar with the language (which is not so easy and doesn't come in 21 days), it will be easier to understand the MFC architecture. Sorry, I don't know of a good book to recommend you but I think there are some 'classes' for that on the web.
But it depends also of your purpose: if you want just to make quick and simple applications then it's ok but I think for that you can use VB (eeeek  ).

Ah ha! You can build and run the project before adding in the code in InitDialog? If so, did you define the variables in the .h file?

Okay.... that appears to be your resource.h file. That defines numerical constants for the controls and such.

Thats a kind request! I now have 25 errors. Here are the errors...
13 of these errors are the same type of synxax error - missing semicolon ; before "do/if/}/while" so I have left these errors out...
'm_bEnableMessage' : Undeclared Identifier
CODE = " m_bEnableMessage = TRUE;)"
Missing function header (old style format list?)
CODE = " ASSERT((IDM_ABOUTBOX & 0xFFF0) == IDM_ABOUTBOX);" (this error is here three times in different places)
'GetSystemMenu' : Function does not take 1 parameters
CODE = " CMenu* pSysMenu = GetSystemMenu(FALSE);"
'm_hlcon' : Undeclered identifier
CODE = " CMenu* pSysMenu = GetSystemMenu(FALSE);"
'Setlcon' : missing storage-class or type specifiers (this error is here twice)
too many initializers
'Seticon' : redefinition;multiple initialization
CODE = " SetIcon(m_hIcon, FALSE); // Set small icon"
it is to do with the initial instructions, like "show a message in the edit box" and these things are not working.
I can send a zip file of this whole thing but I am running late for work at the moment and so I will send this tonight, thanks for helping.

A thought on adobe.. there is an icon up at the top that you can use to select text rather than using the hand. If this pdf file is a legit file & not an illegal copy you can copy the text. If it's an illegal version that was scanned out of a book, you are on your own. Go buy the book and support the process that brought it to the rest of us who have had to learn from it. Also, direct copy/paste of their code is generally not going to yield working code. Read up on what you are doing first.

is it possible to post a message which will be delayed for a fixed time - similar to SetTimer(), but the message is sent only for once?
thx

For this part, you can call KillTimer and specify the ID of your timer. So the timer will be fired only once.

Hello,
Why cann't you use the SetTimer and OnTimer routiens to achive the same??

I have an ActiveX control CPeopleCtrl.
CPeopleCtrl contains method CHuman * GetHuman(BOOL manWomen) that export a male or a women.
How can I add an external method or property for this class method?
I don't know how to expose CHuman...
I'm using VC 6.0
Thanks in advance

An example is DataGrid control activex from microsoft. The control has a method or property GetColumns which return an reference to CColumns. How Microsoft do that? CColumns is not a control... I don't know what is it...

Hi I need some help with global variables in MFC.
How can I have variables accesible form both MyApp.cpp and MyAppDlg.cpp in a dialog based application?
I tried singletons but they don't seem to work...What could be the problem?
Can anyone post a different solution to my problem?
Thx

I guess it should help you:
1. define extern variable and call for it
2. ::AfxGetMainWnd() - define needed type for a value this function return, than return a variable you need.

Hold the variables in MyApp.h private section, also add public accessor functions for the variables.
I suggest you use the variables through the accessors within MyApp class in order to maintain consistency with accessing through other classes.
Within the MyAppDialog you can access these functions like so:
MyApp* pApp = reinterpret_cast<MyApp*>(AfxGetApp());
ASSERT(pApp != NULL);
var = pApp->GetVariable();
where
GetVariable is the accessor function that you want.
var is of the type that GetVariable returns.

I actually tried this one only without reinterpret cast and I got assertion failures....
I'll try it again.
Thank you very much.

Hmmm it doesn't return the correct values...
Too bad... it actually solved the assertion failures...

How is this possible (what have you done in order to determine that the values are incorrect? How have you written the accessor and how is the variable defined?
