Hello,

I want to make a message box which would show me how many points have I earned.

So I have:

unsigned int points;
//code
points++;

MessageBox(hwnd, "You have bla bla", "Total points /*HERE I WANT TO DISPLAY CONTENTS OF points VARIABLE*/, MB_OK);

Is possible to do that?

Yes, assuming this is C you would use sprintf or something equivalent to format the points into your string:

char buffer[100];

sprintf ( buffer, "Total points: %u", points );
MessageBox(hwnd, "You have bla bla", buffer, MB_OK);
ostringstream stm ;
stm << "Total points " << points ;
MessageBox(hwnd, "You have bla bla", stm.str().c_str(), MB_OK);

Well, I know for sprintf. I just wanna know if I can use a variable in MessageBox on other way.

No. MessageBox takes a string. If you want to use a variable, it has to be contained in a string. That should be a pretty obvious restriction given the documentation on MessageBox.

I guess no:

int MessageBox(
HWND hWnd,
LPCTSTR lpText,
LPCTSTR lpCaption,
UINT uType
);

lpText [in] Pointer to a null-terminated string that contains the message to be displayed.

lpCaption [in] Pointer to a null-terminated string that contains the dialog box title. If this parameter is NULL, the default title Error is used.

Why not? It does exactly what you want. You can also use stringstream like what's-his-name suggested if you're writing C++ code. Or you can do any number of things to format a number into a string, but they're all fundamentally the same operation.

Hello Team:

I would like to create a "message box" to print out multiple lines of information on the screen from one of our applications.

My question is what is the "hwnd" operand and how do I define or initialize it? I believe the MB_OK relates to the generation of the message box itself.

Where else can I find out about the creation and use of message boxes using C?

Thanks in Advance....!!!

According to MS, hwnd is a Handle to the owner window of the message box to be created. If this parameter is NULL, the message box has no owner window.
