Hi again (yes, I am new to programming),
How can I show a number that is in a variable in the MessageBox?  There is no "%d" like with printf, hence the question.

Thanx.

To do this, you want to create a temporary CString object.  Then, you can use the "Format" member function to create a string with the value of a variable.  Here is an example:

int var_you_want_shown = 123; // This is the variable you want to display.
CString temp;                 // This is only a temporary buffer.
temp.Format ("The value of var_you_want_shown is %d", var_you_want_shown); // This is similar to "printf"
MessageBox (temp, "Here it is!"); // This is the message box function displaying the temporary string.

Note that this technique can be applied to essentially any data type.  You can use the familiar "%d" "%ld" "%s" and "%f" format strings.  You might consider looking the functions up in the help because it explains all of the format strings.

If you have further questions, please feel free to ask.  Thanks!

this is my way sweet and straight to the answer. :)
char buffer[5];
Messagebox(0, _iota(number, buffer, 10)

_itoa(NUMBER, *buffer/buffer[](which is a pointer), radix/BASE)
