I don't know what is happening here

[abdul]

I want to get the time since my computer was started. I use this function in vb

GetTickCount()

Now, in C++, I used this code to get the time since I started my computer.

long int ticktime;
ticktime = GetTickCount();

Until now, it works fine but now I want to show a messageBox like this:

MessageBox(NULL, ticktime, "The title", MB_OK);

It gives me an error on the variable "ticktime". What is the problem??
