I'm trying to convert this little code from Vba to Vb.net without success.
Would like some help please.
Dim str As String, i As Long
For i = 0 To lstPages.ListCount - 1
If lstPages.Selected(i) Then
If str <> vbNullString Then str = str & "-"
str = str & lstPages.List(i)
End If
Next

So you want the third column, from all selected rows of the ListView, in one string separated by "-"?
Yes that's right.
Then do:
Dim values As New List(Of String)
For Each lvi As ListViewItem In lstPages.SelectedItems
values.Add(lvi.SubItems(2).Text)
Next
Dim str As String = String.Join("-", values)
Debug.Print(str)

I think you could do something like this:
For i as integer = 0 To lstPages.ListCount - 1
If lstPages.Selected(i) Then
If Not String.IsNullOrEmpty(str) Then
str &= "-"
str &= lstPages.List(i)
End If
Next

For an example if column value is "ABC 123 981" need to extract only 123... like so if its "456_wert" need to extract only 456 using access VBA code. Can somebody please help on this.
Parse First Consecutive Digits
Sub StrFirstDigitsTEST()
Const pString As String = "a123.456b"
Dim rString As String: rString = StrFirstDigits(pString)
Debug.Print rString, Len(rString)
' Result:
' 123 3
End Sub
''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
' Purpose: Returns a string's ('ParseString') first consecutive digits
' in a string.
''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
Function StrFirstDigits(ByVal ParseString As String) As String
Dim ResultString As String
Dim Char As String
Dim FoundDigit As Boolean
Dim n As Long
For n = 1 To Len(ParseString)
Char = Mid(ParseString, n, 1)
If Char Like "#" Then
If Not FoundDigit Then FoundDigit = True
ResultString = ResultString & Char
Else
If FoundDigit Then Exit For
End If
Next n
StrFirstDigits = ResultString
End Function
Parsing strings is fairly simple if data has a consistent structure. Does not seem to be the case here so gets complicated. Your second example could be accomplished with Val("456_wert") but because the first example does not follow same pattern, will require more complex code. Probably have to test each character until a number is encountered. Based on samples provided, something like:
Function GetNumber(varS As Variant) As Variant
Dim x As Integer
GetNumber = Null
If varS & "" Like "*#*" Then
For x = 1 To Len(varS)
If IsNumeric(Mid(varS, x, 1)) Then
GetNumber = Val(Mid(Replace(varS, " ", "|"), x))
Exit For
End If
Next
End If
End Function
Place the procedure in a general module and call it from query or textbox.
SELECT table.*, GetNumber([source field]) AS Nbr FROM table;
=GetNumber([sourcefield])
Shouldn't really be necessary to populate a field in table with this extract, however, the SQL would be:
UPDATE tablename SET fieldname = GetNumber([source field])

Basically, I have list of credits in a spreadsheet. Each credit heading on the sheet is displayed as Credit(5) and it displays below that 5 credits i.e:
Credit(5)
Cre1
Cre2
Cre3
Cre4
Cre5
Then I have another heading with Credit(3) and that displays 3 credits below it i.e:
Credit(3)
Cre1
Cre2
Cre3
Now my question is how to do this in VB and relay on the numbers (3) and (5) and display below the heading list according to the number in the heading? so in other words have 5 columns below the heading if heading has (5) and 3 for the other one.
Something like this? Credit to paxdiablo here. Edited.
Private Sub CommandButton1_Click()
Dim sTitle As String
Dim openPos As Integer
Dim closePos As Integer
Dim midBit As Integer
Dim i As Integer
Dim k As Integer
For k = 1 To 50
sTitle = Worksheets("Sheet1").Cells(1, k)
If sTitle <> "" Then
openPos = InStr(sTitle, "(")
closePos = InStr(sTitle, ")")
midBit = Mid(sTitle, openPos + 1, closePos - openPos - 1)
For i = 1 To midBit
Worksheets("Sheet1").Cells(i + 1, k) = "cre" & i
Next i
End If
Next k
End Sub

How can I restrict a textbox to only accept lowercase letters with one uppercase letter, or at least 1 uppercase letter and a number?
To check if a string contains at least one upper character, one lower character and one number, you can use the Char.IsUpper / IsLower / IsNumber methods.
Private Function IsValidPasswordFormat(ByVal text As String) As Boolean
If String.IsNullOrEmpty(text) Then
Return False
End If
If text.Any(Function(c) Char.IsUpper(c)) AndAlso
text.Any(Function(c) Char.IsLower(c)) AndAlso
text.Any(Function(c) Char.IsNumber(c)) Then
Return True
End If
Return False
End Function
suppose that str is the textbox.text
Dim ucount as integer
ucount=0
For Each c As Char In str
Dim charCode As Integer = AscW(c)
If charCode >= 65 AndAlso charCode < 91 Then
ucount += 1
End If
Next
if ucount>1
'do something
End If
In the do something part, for example you can put textbox.text=""

I have an array of 6 digit numbers in which I need to find numbers with same digits but with different order. How can I do this in vba?
I feel a good way to do this would be to take your 6 digit number, create an array containing those 6 digits, sort them, then give you the new number (returned as a string in this example) then compare the two to make sure they are equal.
Public Function SortNumber(intIn As Long)
Dim intArr(1 To 6) As Integer, strResult As String
Dim i As Integer
For i = 1 To 6
intArr(i) = Mid(CStr(intIn), i, 1)
Next i
BubbleSort intArr
For i = 1 To 6
strResult = strResult + CStr(intArr(i))
Next i
SortNumber = strResult
End Function
Function BubbleSort(TempArray As Variant)
Dim Temp As Variant
Dim i As Integer
Dim NoExchanges As Integer
Do
NoExchanges = True
For i = 1 To UBound(TempArray) - 1
If TempArray(i) > TempArray(i + 1) Then
NoExchanges = False
Temp = TempArray(i)
TempArray(i) = TempArray(i + 1)
TempArray(i + 1) = Temp
End If
Next i
Loop While Not (NoExchanges)
End Function

I would like to have a "NumericUpDown" and "DomainUpDown" that would change some text in a text file on a specified line.
Please help.
Example of what i need to edit:
"removePanelsModeSwitcher": true,
on this i need to edit true/false with "DomainUpDown"
and
"x": 235,
"y": -256,
on this need edit the numbers on this with "NumericUpDown"
Here's a quick example:
Dim x As String = Chr(34) & "x" & Chr(34) & ": "
Dim FileName As String = "c:\some folder\path\data.txt"
Dim lines() As String = System.IO.File.ReadAllLines(FileName)
For i As Integer = 0 To lines.Length - 1
If lines(i).StartsWith(x) Then
lines(i) = x & NumericUpDown1.Value & ","
Exit For
End If
Next
System.IO.File.WriteAllLines(FileName, lines)
