Display current system time in msgbox

Question

I got error when I compile the following code, the error tells me that I have to convert unsigned short to char, i dont know how to perform this conversion. I'm using vc6 MFC. This is the code I used.

SYSTEMTIME st;
GetSystemTime(&st);
unsigned short time = st.wHour;
MessageBoxA(TEXT(time),"system time",MB_OK);

Answer 1

You could use a std::ostringstream:

#include <sstream>

...

std::ostringstream time;
time << st.wHour;
MessageBoxA(time.str().c_str(),"system time",MB_OK);

Answer 2

The variable time is an integer, while MessageBoxA wants a string. You have to convert the integer to a string, which is not done by the TEXT macro. I suggest you read up more on either std::stringstream or possibly sprintf.

Answer 3

or ...

char str[20];

sprintf(str,"%d",st.wHour);

MessageBoxA(str,"system time",MB_OK);
