VB 2013 How to Convert Working Code to Dynamic - vb.net

Question

Hello I have a working code for a project i am making...
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
Dim FolderDlg = FolderBrowserDialog1
'Checks if there is a value to the Selected folder
If FolderDlg.SelectedPath = "" Then
'If no value asks to set one
MsgBox("Please Set a Directory")
FolderDlg.ShowDialog()
If DialogResult.OK Then
Button1.Text = Path.GetFileName(FolderDlg.SelectedPath)
End If
Exit Sub
End If
Process.Start("explorer.exe", FolderDlg.SelectedPath)
End Sub
I want to be able to have "AddNew" Button that creates a a copy of this code. I know how to create dynamic buttons but they all call the same FolderBrowserDialog..
EDIT This is My Add New Button That Creates Buttons With Tags And Also Creates FolderBrowserDialogs with Tags.
Private Sub AddNew_Click(sender As Object, e As EventArgs) Handles AddNew.Click
Dim count As Integer = FloLay.Controls.OfType(Of Button)().ToList().Count
Dim button As New Button()
count = FloLay.Controls.OfType(Of Button)().ToList().Count
'button.Location = New System.Drawing.Point(150, 25 * count)
'button.Size = New System.Drawing.Size(60, 20)
button.Name = "button_" & (count + 1)
button.Text = "Button_ " & (count + 1)
button.Tag = "Button_" & (count + 1)
AddHandler button.Click, AddressOf Set_Dir
Dim FolderDlg As New FolderBrowserDialog
count = FloLay.Controls.OfType(Of FolderBrowserDialog)().ToList().Count
FolderDlg.Tag = "FolderDlg_" & (count + 1)
FloLay.Controls.Add(button)
End Sub
EDIT 3 This is My NEW NEW Event Handler
Private Sub Set_Dir(sender As Object, e As EventArgs)
Dim btn = DirectCast(sender, Button)
If btn.Tag Is Nothing Then
Using fbd As New FolderBrowserDialog
fbd.ShowDialog()
btn.Tag = fbd.SelectedPath
End Using
End If
Dim path = CStr(btn.Tag)
' MsgBox(path)
Process.Start("explorer.exe", path)
End Sub
Now only to Add the Button.Name = GetFileNAme and persistance after app restart or reboot
EDIT 4
Private Sub Set_Dir(sender As Object, e As EventArgs)
Dim btn = DirectCast(sender, Button)
If btn.Tag Is Nothing Then
Using fbd As New FolderBrowserDialog
fbd.ShowDialog()
btn.Tag = fbd.SelectedPath
btn.Text = path.GetFileName(fbd.SelectedPath)
End Using
Exit Sub
End If
Dim Folderpath = CStr(btn.Tag)
' MsgBox(Folderpath)
Process.Start("explorer.exe", Folderpath)
End Sub
Now It Works like a Charm!

You can't create a copy of the code. What you need to do is have the code in the event handler determine what to do based on the Button that was clicked. When you create a Button, you can store some data in its Tag property. In the event handler, the sender parameter is a reference to the object that raised the event, i.e. the Button that was clicked. You can then get that data back from its Tag property and use it. You would use that data to configure the FolderBrowserDialog in whatever manner is appropriate for that Button. E.g.
Creating the Button:
Dim btn As New Button
AddHandler btn.Click, AddressOf ButtonClicked
Me.Controls.Add(btn)
Inside the event handler:
Dim btn = DirectCast(sender, Button)
If btn.Tag Is Nothing Then
Using fbd As New FolderBrowserDialog
fbd.ShowDialog()
btn.Tag = fbd.SelectedPath
End Using
End If
Dim path = CStr(btn.Tag)
'Use path here.
Note that the Tag property is type Object so it can be anything you want. It can be as simple as an Integer or as complex as a DataSet. You simply cast it as the appropriate type in the event handler and then access all the data as normal.
