how to remove leading zeroes from a string - vbscript

I have to extract the integer value from a string.
Its actually an amount field.
Say string can be 000000000000512 or 0000040000000
I want only the integer value from this string i.e.; 512/ 40000000
Please help with this in VB scripting

CInt("000000000000512")
See conversion functions: http://msdn.microsoft.com/en-us/library/s2dy91zy.aspx
Use Clng if you expect to have large numbers, as already pointed out in a comment:
Clng("000000004000512")
otherwise you'll have an overflow, as variant's subtype int is 16 bit in vbscript

This will work even with a crazy long number
Function RemoveLeadingZeroes(ByVal str)
Dim tempStr
tempStr = str
While Left(tempStr,1) = "0" AND tempStr <> ""
tempStr = Right(tempStr,Len(tempStr)-1)
Wend
RemoveLeadingZeroes = tempStr
End Function
strNewFileName = RemoveLeadingZeroes("0009283479283749823749872392384")

Use the Absolute Value of the number.
http://ss64.com/vb/abs.html
Var = ABS(Var)

I've used this technique before:
replace the zeros with spaces
left trim
replace the spaces with zeros
Replace(LTrim(Replace(str, "0", " ")), " ", "0")
Note, this doesn't work if str has meaningful spaces in it.

Function TrimLeadingZeros(value)
TrimLeadingZeros = value
while left(TrimLeadingZeros, 1) = "0" and TrimLeadingZeros <> "0"
TrimLeadingZeros = mid(TrimLeadingZeros, 2)
wend
End Function
or
Function TrimLeadingZeros(value)
dim i
i = 1
while i < len(value) and mid(value,i,1) = "0"
i = i + 1
wend
TrimLeadingZeros = mid(value, i)
End Function

Using regex:
Regex.Replace("000000000000512", "^0+", "") ' returns "512"
Regex.Replace("0000040000000", "^0+", "") ' returns "40000000"

In case your string includes digits and characters, use a Do While statement:
string = "00000456ABC"
Do While Left(string, 1) = "0"
string = Right(string, (Len(string)-1))
Loop

Function TrimLZ(str)
If Left(str, 1) = "0" Then
TrimLZ = TrimLZ(Mid(str, 2, Len(str)))
Else
TrimLZ = str
End If
End Function

Unable to compare Array element to String using InStr

I'm using VB6 and I'm trying to compare a string to an Array element. I know that if the string exists it will always be in index 0. Currently it always skips to End If. What am I doing wrong?
Dim attributeFinal As String,
strArray() As String,
stringFound As Integer,
code As String
attributes = "Material=10011,C=123123"
strArray = Split(attributes, ",")
If UBound(strArray) Then
code = strArray(0)
stringFound = InStr(1, "Material", code)
If stringFound <> 0 Then
attributeFinal = code & ",C=" & cCode
End If
End If
Solved thanks to #AndrewMorton. The arguments for comparing strings were in reverse order.
Dim attributeFinal As String,
strArray() As String,
stringFound As Integer,
code As String
attributes = "Material=10011,C=123123"
strArray = Split(attributes, ",")
If UBound(strArray) Then
code = strArray(0)
stringFound = InStr(code, "Material")
If stringFound <> 0 Then
attributeFinal = code & ",C=" & cCode
End If
End If

How capitalize fullname in vb6

hi all i have this question as bellow
how capitalize full in one vb6 Vb6 string variable
‘example
‘my fullname
Dim fullname as string
Fullname = “abdirahman abdirisaq ali”
Msgbox capitalize(fullname)
it prints abdirahmanAbdirisaq ali that means it skips the middle name space even if I add more spaces its same .
this is my own code and efforts it takes me at least 2 hours and still .
I tired it tired tired please save me thanks more.
Please check my code and help me what is type of mistakes I wrote .
This is my code
Private Function capitalize(txt As String) As String
txt = LTrim(txt)
temp_str = ""
Start_From = 1
spacing = 0
For i = 1 To Len(txt)
If i = 1 Then
temp_str = UCase(Left(txt, i))
Else
Start_From = Start_From + 1
If Mid(txt, i, 1) = " " Then
Start_From = i
spacing = spacing + 1
temp_str = temp_str & UCase(Mid(txt, Start_From + 1, 1))
Start_From = Start_From + 1
Else
temp_str = temp_str & LCase(Mid(txt, Start_From, 1))
End If
End If
Next i
checkName = temp_str
End Function
It's far simpler than that. In VB6 you should use Option Explicit to properly type your variables. That also requires you to declare them.
Option Explicit
Private Function capitalize(txt As String) As String
Dim temp_str as String
Dim Names As Variant
Dim Index As Long
'Remove leading and trailing spaces
temp_str = Trim$(txt)
'Remove any duplicate spaces just to be sure.
Do While Instr(temp_str, " ") > 0
temp_str = Replace(temp_str, " ", " ")
Loop
'Create an array of the individual names, separating them by the space delimiter
Names = Split(temp_str, " ")
'Now put them, back together with capitalisation
temp_str = vbnullstring
For Index = 0 to Ubound(Names)
temp_str = temp_str + Ucase$(Left$(Names(Index),1)) + Mid$(Names(Index),2) + " "
Next
'Remove trailing space
capitalize = Left$(temp_str, Len(temp_str) - 1)
End Function
That's the fairly easy part. If you are only going to handle people's names it still needs more work to handle names like MacFarland, O'Connor, etc.
Business names get more complicated with since they can have a name like "Village on the Lake Apartments" where some words are not capitalized. It's a legal business name so the capitalization is important.
Professional and business suffixes can also be problematic if everything is in lower case - like phd should be PhD, llc should be LLC, and iii, as in John Smith III, would come out Iii.
There is also a VB6 function that will capitalize the first letter of each word. It is StrConv(string,vbProperCase) but it also sets everything that is not the first letter to lower case. So PhD becomes Phd and III becomes Iii. Where as the above code does not change the trailing portion to lower case so if it is entered correctly it remains correct.
Try this
Option Explicit
Private Sub Form_Load()
MsgBox capitalize("abdirahman abdirisaq ali")
MsgBox capitalize("abdirahman abdirisaq ali")
End Sub
Private Function capitalize(txt As String) As String
Dim Names() As String
Dim NewNames() As String
Dim i As Integer
Dim j As Integer
Names = Split(txt, " ")
j = 0
For i = 0 To UBound(Names)
If Names(i) <> "" Then
Mid(Names(i), 1, 1) = UCase(Left(Names(i), 1))
ReDim Preserve NewNames(j)
NewNames(j) = Names(i)
j = j + 1
End If
Next
capitalize = Join(NewNames, " ")
End Function
Use the VB6 statement
Names = StrConv(Names, vbProperCase)
it's all you need (use your own variable instead of Names)

How to reduce the decimal length

I want to reduce the decimal length
text1.text = 2137.2198231578
From the above, i want to show only first 2 digit decimal number
Expected Output
text1.text = 2137.21
How to do this.
Format("2137.2198231578", "####.##")
I was about to post use Format() when I noticed p0rter comment.
Format(text1.text, "000.00")
I guess Int() will round down for you.
Been many years since I used VB6...
This function should do what you want (inline comments should explain what is happening):
Private Function FormatDecimals(ByVal Number As Double, ByVal DecimalPlaces As Integer) As String
Dim NumberString As String
Dim DecimalLocation As Integer
Dim i As Integer
Dim LeftHandSide As String
Dim RightHandSide As String
'convert the number to a string
NumberString = CStr(Number)
'find the decimal point
DecimalLocation = InStr(1, NumberString, ".")
'check to see if the decimal point was found
If DecimalLocation = 0 Then
'return the number if no decimal places required
If DecimalPlaces = 0 Then
FormatDecimals = NumberString
Exit Function
End If
'not a floating point number so add on the required number of zeros
NumberString = NumberString & "."
For i = 0 To DecimalPlaces
NumberString = NumberString & "0"
Next
FormatDecimals = NumberString
Exit Function
Else
'decimal point found
'split out the string based on the location of the decimal point
LeftHandSide = Mid(NumberString, 1, DecimalLocation - 1)
RightHandSide = Mid(NumberString, DecimalLocation + 1)
'if we don't want any decimal places just return the left hand side
If DecimalPlaces = 0 Then
FormatDecimals = LeftHandSide
Exit Function
End If
'make sure the right hand side if the required length
Do Until Len(RightHandSide) >= DecimalPlaces
RightHandSide = RightHandSide & "0"
Loop
'strip off any extra didgits that we dont want
RightHandSide = Left(RightHandSide, DecimalPlaces)
'return the new value
FormatDecimals = LeftHandSide & "." & RightHandSide
Exit Function
End If
End Function
Usage:
Debug.Print FormatDecimals(2137.2198231578, 2) 'outputs 2137.21
Looks fairly simple, but I must be missing something subtle here. What about:
Option Explicit
Private Function Fmt2Places(ByVal Value As Double) As String
Fmt2Places = Format$(Fix(Value * 100#) / 100#, "0.00")
End Function
Private Sub Form_Load()
Text1.Text = Fmt2Places(2137.2198231578)
End Sub
This also works in locales where the decimal point character is a comma.

Get each character in a string using VBScript

Is there any way by which we can get each character from a string using VBScript? I had used the Mid function but I just want to know if there are any other direct functions which when used returns each character starting from a string.
strString = "test"
For i=1 To Len(strString)
WScript.Echo Mid(strString,i,1)
Next
a="abcd"
for i=1 to len(a)
msgbox right(left(a,i),1)
next
AFAIK, Mid is the only way to do this.
Another way to do it, starting from 0 :
str = "hola che"
x=Len(str)
text = ""
For i=0 to x-1 'x-1 is because it exceeds the actual length
text= text & Mid(str,i+1,1)
Next
msgbox text
This code is useful to split Ucase and Lcase
Dim a
a="StAcKoVeRfLoW"
for i=o to len(a)-1
if mid(a,i+1,1)=ucase(mid(a,i+1,1)) then
b=mid(a,i+1,1)
msgbox b
end if
next
This works for me. LEFT and then RIGHT....
'Ugandan National Identity Number (NIN) has 14 digits
strFullNIN = "18650929392010"
strNIN_1 = LEFT(strFullNIN,1)
strNIN_2 = RIGHT(LEFT(strFullNIN,2),1)
strNIN_3 = RIGHT(LEFT(strFullNIN,3),1)
strNIN_4 = RIGHT(LEFT(strFullNIN,4),1)
strNIN_5 = RIGHT(LEFT(strFullNIN,5),1)
strNIN_6 = RIGHT(LEFT(strFullNIN,6),1)
strNIN_7 = RIGHT(LEFT(strFullNIN,7),1)
strNIN_8 = RIGHT(LEFT(strFullNIN,8),1)
strNIN_9 = RIGHT(LEFT(strFullNIN,9),1)
strNIN_10 = RIGHT(LEFT(strFullNIN,10),1)
strNIN_11 = RIGHT(LEFT(strFullNIN,11),1)
strNIN_12 = RIGHT(LEFT(strFullNIN,12),1)
strNIN_13 = RIGHT(LEFT(strFullNIN,13),1)
strNIN_14 = RIGHT(LEFT(strFullNIN,14),1)
If I didn't know the length of the initial string, I would do as follows:
strFullNIN = RS.fields("Client_NIN")
strFullNIN_LENGTH = LEN(strFullNIN)
x = 1
DO UNTIL x = strFullNIN_LENGTH
IF x = 1 THEN
strNIN_"& x &" = LEFT(strFullNIN,x)
ELSE
strNIN_"& x &" = RIGHT(LEFT(strFullNIN,x),1)
END IF
x=x+1
LOOP
Hope this is helpful to someone!

What is the best vbscript code to add decimal places to all numbers in a string?

Example
G76 I0.4779 J270 K7 C90
X20 Y30
If a number begins with I J K C X Y and it doesn't have a decimal then add decimal.
Above example should look like:
G76 I0.4779 J270 K7. C90.
X20. Y30.
Purpose of this code is to convert CNC code for an older Fanuc OPC controller
Set RegEx = New RegExp
RegEx.Global = True
RegEx.Pattern = "([IJKCXY]\d+)([^\.]|$)"
newVar = RegEx.Replace (oldString, "$1.$2")
Where oldString is the original string, and newVar is the string with the decimals added.
function convert(str)
Set RegEx = New RegExp
RegEx.Global = True
RegEx.Pattern = "([IJKCXY]\d*\.?\d*)"
Set Matches = regEx.Execute(str)
For Each Match in Matches
if instr(Match.value, ".") = 0 then
str = Replace(str, Match.value, Match.value & ".")
end if
Next
convert = str
end function
tloach still answer doesn't work
Waynes works but also puts a . after every occurrence of IJKCXY
I changed if instr(Match.value, ".") = 0 then
To be like if instr(Match.value, ".") = 0 and len(Match.value) > 1 then
