This line If Trim(Sites) = Trim(strSiteCode) Then is supposed to find the matching entry in both Sites and R03sites files ie. BEC , BEC and then process the shortcut creation and write to console if no match is found. Then loop through the rest of the file. I would like to learn how to make it stop when it finds the match but I can't even make it work the way I need it to yet.

Yes and what else were you told to do? Did you do either one? I would guess not as this is the same code with the exact same problem.

Okay, so I have an idea for a little quick addition to a program that I thought could be simple but I cant exactly find any information on it nor confirmation that it is even possible in visual basic.
I am using vb6, but I can also use .net if it this is not possible in vb6.
So here is my question. I have a text box where a number will be inputted from another aspect of the whole program. The inputted text will be 84 characters long. I need a command button to delete the first 46 and last 4 characters. For the grand finale, I need that number to be inverted!
Now, I have racked my brain for weeks on this little debacle and have not come up with anything.
I hope that someone has an idea on what to do with this.
I have also been thinking, I can due without the inverting of the numbers because I'm not sure that is t all possible. Or, if I need to, I can make it into two command buttons.
This is merely an aspect of a larger working program so Id rather not re write this in another language. However, it is also just for fun (hence why I wanted to do it in vb6) so I'm not going to cry if it doesn't work out.
Thanks for any help at all

Okay... since you didn't say what you needed help with...
Member 12961546 wrote: I'm not sure that is t all possible
Yes, it is possible. VB6 has a Left, Right and StrReverse functions so I fail to see why you think that this is a problem at all.

In a vb.net 2010 application, I have the following code that works sometimes:
Dim txtOrigAddress As String = _attendanceLetterOrig.Substring(CInt(_attendanceLetterOrig.IndexOf("ADDR_BEG")), _attendanceLetterOrig.IndexOf("ADDR_END") - _attendanceLetterOrig.IndexOf("ADDR_BEG"))
Dim txtOrigAddress As String = _attendanceLetterOrig.Substring(CInt(_attendanceLetterOrig.IndexOf("ADDR_NEXT")),4)
The problem is the folllowing values do not exist:
_attendanceLetterOrig.IndexOf("ADDR_BEG")
_attendanceLetterOrig.IndexOf("ADDR_END")
_attendanceLetterOrig.Substring(CInt"ADDR_NEXT")
What kind of an edit can I use to check if the 3 values listed above actually exist? I want to prevent application errors.
Would you show me the code to see if the values really exist?

If the substring isn't found, IndexOf returns -1. You'll need to find and store each index first, then check that they're not -1 before calling Substring.
Also, IndexOf already returns an Integer. There's no need to call CInt.
Dim startIndex As Integer = _attendanceLetterOrig.IndexOf("ADDR_BEG")
Dim endIndex As Integer = _attendanceLetterOrig.IndexOf("ADDR_END", startIndex)
If startIndex <> -1 AndAlso endIndex <> -1 Then
Dim txtOrigAddress As String = _attendanceLetterOrig.Substring(startIndex, endIndex - startIndex)
End If
Your second example makes no sense. The IndexOf method returns the index of the start of the matched substring, if found. So _attendanceLetterOrig.IndexOf("ADDR_NEXT") returns the index of "A", and _attendanceLetterOrig.Substring(..., 4) will always return "ADDR".

If you think someone is just going to hand you code you're sorely mistaken.
The only code you're going to get is the code YOU write.
Now, if you have a question I suggest you describe the problem you're having, in detail, and we'll see what see can do.

i have a app and in this app have a class inherits from datagridview. basically i try to create a datagridview with specific properties and it will be generated automatically as a control of a panel. after program starts, datagridview is created and retrieves some data from database. so far everythings ok.
Public Class grid
Inherits DataGridView
Private _dgv As New DataGridView
Public Property Dgv
Set(value)
_dgv = value
End Set
Get
Return _dgv
End Get
End Property
Public Sub New()
End Sub
Public Sub New(panel As Panel)
_dgv.Name = "dgv"
_dgv.Parent = panel
_dgv.AllowUserToAddRows = False
_dgv.AllowUserToDeleteRows = False
_dgv.ReadOnly = True
_dgv.DefaultCellStyle.Alignment = DataGridViewContentAlignment.MiddleCenter
_dgv.Dock = DockStyle.Fill
_dgv.SelectionMode = DataGridViewSelectionMode.FullRowSelect
_dgv.DefaultCellStyle.SelectionBackColor = Color.LightGray
_dgv.DefaultCellStyle.SelectionForeColor = Color.Black
_dgv.AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.Fill
_dgv.ColumnHeadersDefaultCellStyle.Alignment = DataGridViewContentAlignment.MiddleCenter
End Sub
End Class
using panel.controls.add(grid) routine for loading datagridview to panel.
my question is after datagridview generated how to triger cellmousedoubleclick event?
using vb.net 2012.
thanks in advance.

You can call an event like a method, if you provide the correct arguments.

I managed. Actually there were more than one problem in my app. This question was just a step 1. But i did it all. I would like to explain how i did it.
The exact thing that i expect from my app is a custom genereted dgw and its celldouble click event firing. after that event happens another form pops up with controls on it and those controls retrieves data from sql server db.
How i did it the codes are below. not good programming i guess. any suggestions?
Public Sub New(panel As Panel)
_dgv.Name = isim
_dgv.Parent = panel
_dgv.AllowUserToAddRows = False
_dgv.AllowUserToDeleteRows = False
_dgv.ReadOnly = True
_dgv.DefaultCellStyle.Alignment = DataGridViewContentAlignment.MiddleCenter
_dgv.Dock = DockStyle.Fill
_dgv.SelectionMode = DataGridViewSelectionMode.FullRowSelect
_dgv.DefaultCellStyle.SelectionBackColor = Color.LightGray
_dgv.DefaultCellStyle.SelectionForeColor = Color.Black
_dgv.AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.Fill
_dgv.ColumnHeadersDefaultCellStyle.Alignment = DataGridViewContentAlignment.MiddleCenter
AddHandler _dgv.CellDoubleClick, AddressOf dgvClick
End Sub
Public Sub dgvClick(sender As Object, e As System.Windows.Forms.DataGridViewCellEventArgs)
Dim sql As New SQLAraclari
sql.DBDT = Nothing
If e.RowIndex = -1 Then
Return
End If
If isim = "Sifreler" Then
Try
UserID = Convert.ToInt32(Dgv.CurrentRow.Cells(0).Value)
MsgBox(userID.ToString)
Catch ex As Exception
MsgBox(e.ToString)
End Try
sql.SorguyuCalistir("SELECT tblPersoneller.PerID, PerAdi, PerSoyadi, PerKullaniciAdi, PerSifre FROM tblPersoneller JOIN tblPersonelSifreler ON tblPersoneller.PerID = tblPersonelSifreler.PerID WHERE tblPersonelSifreler.PerID = " & UserID & ";")
For Each r As DataRow In sql.DBDT.Rows
frmSifreGir.txtAdi.Text = r("PerAdi")
frmSifreGir.txtSoyadi.Text = r("PerSoyadi")
If String.IsNullOrEmpty(r.Item("PerKullaniciAdi").ToString) Then
frmSifreGir.txtKullaniciAdi.Text = ""
Else
frmSifreGir.txtKullaniciAdi.Text = r("PerKullaniciAdi")
End If
If String.IsNullOrEmpty(r.Item("PerSifre").ToString) Then
frmSifreGir.txtSifre.Text = ""
Else
frmSifreGir.txtSifre.Text = r("PerSifre")
End If
Next
If sql.HataVarmi(True) Then MsgBox(sql.Exception)
frmSifreGir.Show()
ElseIf isim = "Kayitlar" Then
Else
End If
End Sub

You're creating a new database-object and then checking the rowindex;
If e.RowIndex = -1 Then
Return
End IfWould you not want to do that as the first thing in the event? If it is -1, you won't need the database anyway.
I'd also recommend using the IDbConnection/IDbCommand structures to query a database; it is more recognizable and easier to maintain.
