How do I display a variables value in a label?

I've asked 2 multiple-question posts and one of those questions has been "how do I display a variables value in a label?", but I never got an answer to that.
Now that is my question, how do I display a variables name in a label?
For example if I want to display something like this:
"Im showing the number 10 because I want to"
where the number 10 is a variables value.
In a DOS window I would write it like this:

C++

int main()
{
int Number = 10;
cout << "Im showing the number " << Number << " because I want to";
return 0;
}

But how can I do it in a label (inside a Windows Application)?

Thank You! :)

From your previous questions I suspect that you are using C++\CLI, but your question is tagged as C++, which refers to native C++. Please clarify this, because setting the label text is quite different in Native C++ Windows applications than C++\CLI WinForms appapplications.

If I understood your problem properly than first you have to convert the integer value to string and using SetWindowText you display that string to label.

Sorry if I sound like a total noob, but how exactely do I convert a integer value to a string with the SetWindowText thing?
By the way, by using SetWindowText can I set the string to whatever the value was from the variable without having to use if statements to check the value?

Err ?? You can convert the int to string using
CString str;
int x;

x =6;
str.Format("%d", x);

and using SetWindowText you can display the string in Label. I mean to say that if you are using Static control as label.

I still don't understand, if I were to display text to a label I would use the library "windows.h" and write it like this:

this->label1->Text = L"Text";

but do I need to write it in a completely different way to display a string (would prefer if you could write it in code if you dont mind).
And what do I need to include for the "str.Format", because it says it's a undeclared identifier.

Thanks for your help! :)
