i want my code to become faster

hi, how to become my code faster?

this is my code:

VB Code:

Private Sub cmdFeed_Click()
Dim ln As Integer
For ln = 1 To Len(txtMobileNumber.Text)
Select Case Mid(txtMobileNumber.Text, ln, 1)
Case "0"
thex ("1F 00 10 D1 00 06 00 01 46 00 01 0A 03 97")
pause (100)
thex ("1F 00 10 D1 00 06 00 01 47 00 01 0C 04 97")
pause (100)
Case "1"
thex ("1F 00 10 D1 00 06 00 01 46 00 01 01 03 9C")
pause (100)
thex ("1F 00 10 D1 00 06 00 01 47 00 01 0C 04 97")
pause (100)
Case "2"
thex ("1F 00 10 D1 00 06 00 01 46 00 01 02 03 9F")
pause (100)
thex ("1F 00 10 D1 00 06 00 01 47 00 01 0C 04 97")
pause (100)
Case "3"
thex ("1F 00 10 D1 00 06 00 01 46 00 01 03 03 9E")
pause (100)
thex ("1F 00 10 D1 00 06 00 01 47 00 01 0C 04 97")
pause (100)
End Select
Next ln
End Sub

I could be missing something... but wouldn't taking out the pauses, or reducing them make it faster??


Don't listen to me. Ever. Surveillance.

Surveillance, reducing with the pause? e.g pause(50) ?
btw, the use of this code is when u input in the txtMobileNumber e.g 012 then if u press cmdFeed it will dial on ur Mobile Phone 012

thanks..

Moved.

Yes, like pause(50) or whatever... the only thing I have to ask is, are you sure that pause isn't there for a reason? Maybe to give the phone time to do its thing. But play around with it and see where you can optimize it at.

this is the module..

VB Code:

Sub pause(pas As Single)
start = Timer
Do Until Timer >= start + pas / 1000
DoEvents
Loop
End Sub

i tried the pause(50) but there is an error my phone freeze..

Hmm, it looks like even with it at 100 it's only pausing for a 1/10th of a second. I don't see why it should freeze, unless it needs that full 1/10th of a second between inputs. Maybe try speeding it more gradually, until you hit the sweet spot, try (90), and if it doesn't freeze, move down to (80) or so, until you can't get it faster.

VB Code:

Declare Sub Sleep Lib "kernel32" ( _
    ByVal dwMilliseconds As Long _
)
 
Private Sub cmdFeed_Click()
Dim ln      As Long
Dim lTemp   As Long
Dim sChar   As String
 
    For ln = 1 To Len(txtMobileNumber.Text)
        lTemp = CLng(Mid$(txtMobileNumber.Text, ln, 1))
        If (lTemp = 0) Then
            sChar = "0A"
          Else
            sChar = "0" & CStr(lTemp)
        End If
 
        thex "1F 00 10 D1 00 06 00 01 46 00 01 " & sChar & " 03 97"
        Sleep 100
 
        thex "1F 00 10 D1 00 06 00 01 47 00 01 0C 04 97"
        Sleep 100
    Next ln
End Sub

As has been mentioned, the slowest part is really the pause. Unless you can improve that there is not much point optimising the rest of the code since the pause is the limiting factor.

penagate,

hi, i got an error from the declare it says only Constants,Fixed Length strings,arrays,user-defined types and declare statements not allowed as public members of object modules

Thanks..

Indeed, you need to either chuck that part in a standard module or make it Private ;)
