Appears where? I can't see what's going on there so please be specific! 
Maybe your project needs to be compiled with unicode enabled?

ok
When you write a code for exemple, 'messageBox' and you pass a cursor of mouss, it apear MessageBoxW and it return int, i woul show amessage .thank you

That's fine. Most of the windows APIs have both ANSI and Unicode versions (in the case of
MessageBox() there's MessageBoxA() and MessageBoxW()). If you are seeing MessageBoxW then that
means your app is being compiled for Unicode.

but why i can show a message, when write Messagebox.show don't work, like printf !!!, i have a Mfc application
|
|

I'm sorry I'm not understanding. What are you trying to do - show a message box or use printf?
And what is not working - It's not compiling? Not working a runtime?

Thank you very mutch to answer my questions , but last thinks, when i add Netica.lib on Linker-> input when i debug a error appear:
fatal error LNK1104: cannot open file 'C:\Documents.obj'
Thank you very mutch

Somewhere in the linker settings for your project, documents.obj is expected.
It's looking for it in the C:\ folder - that's probably not where it is.

hello everybody in this forum.
i have some problems .
i want to make a dll in C++ that i can use in C# i declare the function by
<br />
extern "C" __declspec(dllexport) void DisplayMessage()<br />
{<br />
std::cout << "Hello world !!!";<br />
}<br />
when i call this function , from C# using interoperability services , the calling is excellent and i can call this function from Managed code.
ok but when i try to make a class for the following example
<br />
class Grade<br />
{<br />
public:<br />
void DisplayMessage();<br />
};<br />
<br />
public Grade<br />
{<br />
void DisplayMessage()<br />
{<br />
std::cout << "Hello Snouto Override" <<std::endl;<br />
}<br />
}<br />
<br />
<br />
extern "C" __declspec(dllexport) void ShowMessage()<br />
{<br />
Grade current_grade;<br />
current_grade.DisplayMessage();<br />
}<br />
then when i create and compile the above code into .dll using win32 Dll Project.
<br />
[DllImport(mydll.dll)]<br />
public static extern void ShowMessage();<br />
<br />
<br />
private static void Main(string[] args)<br />
{<br />
ShowMessage();<br />
}<br />
i have error telling me NullReferenceException was thrown but i don't know why.

Try posting the surrounding code, and tell us the compile error you're getting. We need a little more detail.

Implement a game named as TIC TAC TOE in C++ with the help of 2D Arrays.
RULES & CONSTRAINTS:
• Tic Tac Toe is played on a 4 x 4 grid.
• Two players play at a time, one can place X’s on the board, the other O’s.
• Players have alternate turns.
• The player who obtains 4X’s or 4O’s first vertically, horizontally, or diagonally wins.
• The already occupied place cannot be reoccupied.

Wow. I must be old. Why, when I was a youngster, we played tic-tac-toe on a 3x3 grid.
You kids are crazy!
Oh yeah, which part is giving you trouble?

Inflation - it affects everything!

Is this a New Version of this game? It was Trivial on 3x3. Whoever started on 3x3 would be the winner, if (s)he started in the correct square. Maybe 4x4 is not trivial.
Looks like a Nice Homework project though.
You don't specify a User Interface. A common misconception I found amongst some budding programmers was that Windows and CPP are somehow the same. I can assure you, The're NOT. It is merely that Microsoft wrote a large body of code in cpp,to use windows. The body of code was called MFC for Microsoft Foundation Classes.

Are you sure? I seem to remember that unless someone makes a mistake, no-one wins (i.e. second player can always play such that first player does not win.)

i want to convert LPWSTR in to STL basic string.
Amit

|
|
|

USES_CONVERSION;
string s(W2A(myLPSWSTR));
that's one way.

The STL has two typedefs which are shortcuts for specialisations of basic_string: std::string and std::wstring. If you're working with LPWSTRs then you probably want std::wstring. Here's an example:
std::wstring s = L"Hello";
