Contents |
Description
Create a formatted string.
expression
The format string and flags to use (see Remarks).
expressions
Variables that will be output according to the "Format Control".
Return Value
Success: Returns the formatted string.
Failure: Returns an empty string.
Remarks
Warning: If you expect to use int, byte, float etc in the params then you must cast it as such for example:
$myint = 100 $val = SPrintf("Value is 0x'{0:x}'", (int)$myint) ; The (int) will only take in $myint $myint = 100 $myint2 = 100 $val = SPrintf("Value is 0x'{0:x}'", (int)($myint + $myint2)) ; The (int) will now take in $myint AND $myint2
Note how $myint was cast as an int? using (int)$myint this is vital since if you dont do that it might send a string or a float you never really know with $variables so its best to cast it.
There is an alternative method example:
$myint = 100 $val = SPrintf("Value is 0x'{0:x}'", int($myint))
Its up to you to decide which one to use.
Go see Printf( <expression>, <expressions>... ) for details on the format string
Anything thats valid for Printf to print to console window is also valid for SPrintf to use to create strings.
Example
$val = SPrintf("Value is 0x'{0:x}'", (int)100) Printf($val) ; Prints 0x64 since the {0:x} is telling it to place param 0 as :x meaning hex
