Trying to use the format method in vb.net
to oconvert a double to string of 4 places

I tried:
Format(CStr(dHeightOfStone), "x.xxxx")

and:

Format(CStr(dHeightOfStone), "#.####")

It returns "x.xxxx" or "#.####" instead of "36.1875" (or whatever number was
input)

any tips?

thanks mark

These format strings are for formatting numbers. You are trying
to format strings because, before, you've converted the numbers
to strings using the CStr function. Try this instead:

dHeightOfStone.ToString("#.####")

I believe you want to use Format(dHeightOfStone, "#.####").

Frankly, I prefer dHeightOfStone.ToString("f4"), but that's just my style...

ok, even though the help files show the order i first tried,
> Format(CStr(dHeightOfStone), "#.####")
i tried the opposite order
> Format( "#.####", CStr(dHeightOfStone))
now instead of getting "#.####" returned, i get
4.62500000000364

so it's still not formatting
what am i missing?

as an alternative i tried using round
Dim sWidthLiner As String =
CStr(Decimal.Round(Cdec(dLengthOfMoldSidesLiner), 4))

but it seems a long way around to just get a double rounded to x places and
converted to string

thanks
mark
