Proper way of converting int to LPCWSTR (Win32)

Question

I'm attempting to learn basic Win32 programming and running into a frustrating problem. I wish to convert a variable (Call it NumClicks) and display it as the application name (as part of a string). From what I've seen, going from int + some block of text to a char* is problematic, because converting it to the requisite end data type(LPCWSTR) is more difficult than a straight casting.

Any ideas or links?

Answer 1

use wsprintf
It allows you to compose a string the same way printf allows you to print a line of text.

Answer 2

_itow_s

If you're looking for more than just INT to LPWSTR conversion (such as formatting), I'd suggest StringCchPrintfW.

Answer 3

rather than use wsprintf i would use sprinf(buf, "%S", "plain old string");

Answer 4

Here is the code I used, when I needed LPCWSTR:

int f =55;  
wchar_t buffer[10];
_itow_s (f, buffer, 10);
func_using_lpcwstr_as_parameter(buffer);

watch for buffer overflows in this sample
