Change Format to hex

Hello experts,

My question that I've been stuck on for a while is how can i add "0x" in front of a number without changing the actual number itself.

In VC++ using namespace System It can be done like so..
int Number = 123456;
txtNumber->Text = Number.ToString("X8")

Open in new window

txtNumber->Text will show "0x123456".

But i want to do that exact thing without using the namspace System, and System::String.

and one more thing instead of having the number displayed into "txtNumber->Text" I'd rather have it be put back into "int Number". So each time i use "Number" it'll equal "0x123456".

Thanks for your help.

The number 123456 is Not the same as 0x123456.  Try it in your calculator.  0x123456 = 1193046 decimal.

@DaveBaldwin - Yes I'm aware of that, I merely just want to add "0x" infront of any number. or if this makes things easier. Make 1193046 into 0x123456 within "int Number".

That isn't going to do what you think.  The '0x' is just a display method, not a change in the number.  Normally you would just use 'printf' with the 'x' specifier to get the number to display in hex instead of decimal.  http://msdn.microsoft.com/en-us/library/wc7014hz%28v=vs.71%29.aspx
