Single Digit to Double Digit

[Mantis]

Can I use the expression editor to make a single digit 0-9 number double digit, so 00-09? I'm dealing with time here, so hours/minutes/seconds. It would take a number of conditions to check if all three values are 0-9 at once, so if there's an easy solution for this I'd like to know.

Thanks.

Found an old thread. Mods may as well delete this unless someone else might find this useful.

Situation not averted. I'm trying to use this, keep in mind CurrentSecond is a global variable.

Str$( Left$("0",2-Len(Str$(value(CurrentSecond))))+Str$(value(Curren tSecond)) )

The number two is causing the problem. I'm not very good with expressions so I'm probably doing something very stupid. Anyway, I'd appreciate any help.

Assuming you are using two counters, could you not simply say, "If counter 1 = 99" then add to the condition "If counter 2 = 99", do etc.

What you're doing here is taking as many characters as needed from the string "0" to fill up the remainder of the string (one 0 if the original value is 1 digit long, or none if it's two - therefore, (2 - the length of the original string) zeroes), then putting the original value (in string form) after it.

If the value is 1 digit long (e.g. "7"):

Left$("0", 2-1) = "0" (the first 1 characters of the string "0") + "7"

= "07"

If the value is 2 digits long (e.g. "94"):

Left$("0", 2-2) = "" (No characters of the string "0") + "94"

= "94"

So the expression is - set string to:

Left$("0", 2-Len(Str$(value(CurrentSecond)))) + Str$(value(CurrentSecond))

You appear to have rather more brackets and stages than necessary in your original expression, but it's difficult to tell without syntax highlighting.

Yeah, I forgot to remove the Str$ at the beginning which I added hoping it would help. Otherwise it's the same as on the link I provided above. I have nothing to do with the expression that's written, other than adding in the global values.

Ausomeman, I'm not using counters. I'm retrieving the system date and time and setting global values to these numbers.

[DavidN]

Oh, I never noticed you were using global values - you don't need value(), in that case. That's for retrieving the value of a counter object.

Left$("0", 2-Len(Str$(CurrentSecond)))+Str$(CurrentSecond)

[Mantis]

Ah, right! It works, thanks.

There is a simple option on the counters somewhere that allows them to be displayed with multiple digits. so one is displayed as 01. no need for events.

[Mantis]

That is true. But when converted to string, it becomes single digit.
