How to ?

I am about to extract bytes from a certain integer value.
An if i write 14200,05 i shall get this :
01, 42, 00, and 05,
With 950 i shall get 00 09 50 00 also with 950,00 :-)
With 1247,36 i shall get 00 12 47 36
I declare 4 variables F1, F2, F3 and F4.
Max is 30000,00 and min is 130,00

When i am using this code i make the number 950 correct, but is it wrong to
use "select case" here ?

Private Sub Command1_Click()
Dim Frekvens As Double
Dim grunn As Double
Frekvens = txtFrekvens
grunn = Frekvens * 100   ' to make 130,05 possible :-)

Dim F1 As String
Dim F2 As String
Dim F3 As String
Dim F4 As String
Dim Fa As String
Dim Fb As String
Dim Fc As String
Dim Fd As String
Dim Fe As String
Dim Ff As String
Dim Fg As String
Select Case grunn
Case Is >= 13000 And grunn < 100000
F4 = Right(grunn, 2)
lblF4 = F4
F1 = "0" & "0"
lblF1 = F1
Fa = Left(grunn, 1)
F2 = "0" & Fa
lblF2 = F2
Fb = Left(grunn, 3)
F3 = Right(Fb, 2)
lblF3 = F3
Case Is >= 100000 And grunn < 1000000
F4 = Right(grunn, 2)
lblF4 = F4
F1 = "0" & "0"
lblF1 = F1
F2 = "0" & Left(grunn, 3)
lblF2 = F2
Fc = Left(grunn, 4)
F3 = Right(Fc, 2)
lblF3 = F3
Case Is >= 1000000 And grunn <= 3000000
F4 = Right(grunn, 2)
lblF4 = F4
Fd = Left(grunn, 2)
F1 = Fd
lblF1 = F1
Fe = Left(grunn, 3)
F2 = Right(Fe, 2)
lblF2 = F2
Ff = Left(grunn, 5)
F3 = Right(Ff, 2)
lblF3 = F3
End Select
Form1.txtFrekvens.SetFocus
End Sub

Where am i off the track ?

Thanks anyone !

There is a much easier way to do this, using the Format function to fix the
number of decimal places before and after the decimal separator:

Dim grunn As Double
Dim F1 As String, F2 As String
Dim F3 As String, F4 As String
Dim sGrunn As String
grunn = 14200,05
sGrunn = Format\$(grunn, "000000.00")
F1 = Left\$(sGrunn, 2)
F2 = Mid\$(sGrunn, 3, 2)
F3 = Mid\$(sGrunn, 5, 2)
F4 = Right\$(sGrunn, 2)

Hi Torbj?rn,

I agree with the previous poster that there is an easier way to do what you
want. But the reason your approach did not work is that the Case statements in
a select must be a single value as in:

select (a)
Case 1:
'Handle Case 1
Case 2:
'Handle Case 2
Case 3:
'Handle Case 3
end select

to do a range check you should use if then else if else if as in:

if (grunn >= 13000) And (grunn < 100000) then
F4 = Right(grunn, 2)
lblF4 = F4
F1 = "0" & "0"
lblF1 = F1
Fa = Left(grunn, 1)
F2 = "0" & Fa
lblF2 = F2
Fb = Left(grunn, 3)
F3 = Right(Fb, 2)
lblF3 = F3
else
if (Grunn >= 100000) And (grunn < 1000000) then
F4 = Right(grunn, 2)
lblF4 = F4
F1 = "0" & "0"
lblF1 = F1
F2 = "0" & Left(grunn, 3)
lblF2 = F2
Fc = Left(grunn, 4)
F3 = Right(Fc, 2)
lblF3 = F3
else
if (Grunn >= 1000000) And (grunn <= 3000000) then
F4 = Right(grunn, 2)
lblF4 = F4
Fd = Left(grunn, 2)
F1 = Fd
lblF1 = F1
Fe = Left(grunn, 3)
F2 = Right(Fe, 2)
lblF2 = F2
Ff = Left(grunn, 5)
F3 = Right(Ff, 2)
lblF3 = F3
end if
end if
endif

I didn't check your logic within each if block but this is how you should
test your various conditions rather than using a Select case statement. Hope
this helps

How to ?
Have you looked into using the Format() command?

strTemp = Format\$(input, "000000,00")
If Val(strTemp) > 30000 Or Val(strTemp) < 130 Then
Exit Sub
End If
lblF1.Caption = Left\$(strTemp, 2)
lblF2.Caption = Mid\$(strTemp, 3, 2)
lblF3.Caption = Mid\$(strTemp, 5, 2)
lblF4.Caption = Right\$(strTemp, 2)

Snip...

Thank you for this one Richard, it worked nicely !

Using MSComm in VB4.0 i would like to send each of theese values, F1 to F4
and another number in Hex out on com1/2.

How ?

Comm1.Output = lblF1 + lblF2 etc... ?
Or how else ?
