Listbox help

[NewHSKid]

Hi all, I posted this a couple days ago but didn't get any response. Thought i would try to post it again and see if someone could help. Wanted to know if it is possible to both pad a hex numbers with leading 0's and also format the width of the message. I have a string and i just concat a hex number to it. I just want to space out the numbers so that they will line up with the next string added, so that it has the look of a table. Right now i am padding the hex number like this:

int myString = 10005;
int myString2 = 20003;
testStr.Format("%03X" , myString);
Str += testStr;
testStr.Format("%03X" , myString2);
Str += testStr;
Listbox.AddString(Str);

I know if i take away the 0, then it will set the width, but i need to do both. CAN THIS BE DONE? thanks in advance. Jimmy Just cause I am 15, doesn't mean I'm dumb! (I'll really be 4 on Feb. 29...the year 2004)

You could do it in two stages, format the hex value, then take that as further input to another Format call, using %8.8s (pad on right) or %-8.8s (pad on left) as the format string second time around eg testStr1.Format("%03X",myString); testStr2.Format("%03X",myString2); Str.Format("%10.10s%10.10s",testStr1,testStr2); Steve S I was 15 once.

and, (haven't used Format or printf for a while...) you can specify the field width as an argument itself, like this; testStr.Format("%0*X", n, myString) where n is the number of digits you want. Steve S
