the function fmt helps you to format a string in vbscript as you do in c.
in c, if you write:
printf( "this is %s number %d", "test", 1 );
then you would use the function fmt in vbscript like this:
dim str
str = fmt( "this is %x number %x", array("test", 1) )
details
the complete function looks like this:
' works like the printf-function in c.
' takes a string with format characters and an array
' to expand.
'
' the format characters are always "%x", independ of the
' type.
'
' usage example:
' dim str
' str = fmt( "hello, mr. %x, today's date is %x.", array("miller",date) )
' response.write str
function fmt( str, args )
dim res ' the result string.
res = ""
dim pos ' the current position in the args array.
pos = 0
dim i
for i = 1 to len(str)
' found a fmt char.
if mid(str,i,1)="%" then
if i<len(str) then
' normal percent.
if mid(str,i+1,1)="%" then
res = res & "%"
i = i + 1
' expand from array.
elseif mid(str,i+1,1)="x" then
res = res & cstr(args(pos))
pos = pos+1
i = i + 1
end if
end if
' found a normal char.
else
res = res & mid(str,i,1)
end if
next
fmt = res
end function
the format character is always %x, independent of the actual type, since vbscript has no direct types like integer or string.
