I'm using this book for C++ .Net that I mistakenly bought awhile back because I thought it was for C++ (not .Net). I had forgotten that I had it.
So now I can actually use it because I [MyndFyre-Edit]legitimately acquired[/MyndFyre-Edit] Visual Studio .Net.
Back on topic.
I am told to code:
MessageBox::Show(S"It worked!", S"Message...");
However, I can't compile it. It gives me two errors that make completely no sense.
Quote
c:\Documents and Settings\John Doe\Desktop\Forms\CppForm.cpp(24): error C2653: 'MessageBoxA' : is not a class or namespace name
c:\Documents and Settings\John Doe\Desktop\Forms\CppForm.cpp(24): error C2660: 'System::Windows::Forms::Control::Show' : function does not take 2 arguments
This is totally whack. I am not trying to use this "MessageBoxA". wtf. I didn't even type that in...
I am definitely sure that I have included the right #using information and namespaces because I'm done every step-by-step instruction that I was given.
Anyone have any idea what the problem is?
Just to be sure, you definitely included:
#using <System.Windows.Forms.dll>
using namespace System::Windows::Forms;
?
Also, you're probably #including <windows.h>, right? Well, I believe <windows.h> includes a #define something like this:
#ifdef UNICODE
#define MessageBox MessageBoxW
#else
#define MessageBox MessageBoxA
#endif
Amazing! I just did an MSDN library search to see what header it was in, but hell I didn't need to! This article (http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vcmxspec/html/vcmg_macrosandthepreprocessor.asp) describes exactly the problem you're having! :)
