1. You will want to use the FolderBrowserDialog for the user to select both the input & output folders.
2. For your list you will want to use a ListView control with the CheckBoxes property set to True.
3. After the you have the folder path, you will want to use the Directory.GetFiles() method to retrieve the path.
4. Then you will want to use a loop, checking each file name to see if it ends with '.pdf', if it does then add it to the list.

Hope this helps

Use the Directory.GetFiles overload that takes a search pattern: Directory.GetFiles Method (String, String) (System.IO).

Here's a little example:

'Button: btnInput
'Button: btnOutput
'Button: btnGenerate
'TextBox: txtInput
'TextBox: txtOutput
'ListView: lstFiles (CheckBoxes=True)
'FolderBrowserDialog: FolderBrowser1

'Imports System.IO

Private Sub btnInput_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnInput.Click
    txtInput.Text = FolderBrowser1.ShowDialog
    If txtInput.Text.Length = 0 Then Exit Sub
    For Each File As String In Directory.GetFiles(txtInput.Text)
        If File.ToLower.EndsWith(".pdf") Then
            lstFiles.Items.Add(File)
        End If
    Next
End Sub

Private Sub btnOutput_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnOutput.Click
    txtOutput.Text = FolderBrowser1.ShowDialog
End Sub

Private Sub btnGenerate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnGenerate.Click
    If txtOutput.Text.Length = 0 Then Exit Sub
    For i = 0 To lstFiles.Items.Count - 1
        If lstFiles.Items(i).Checked = True Then
            'Add your signing code here
        End If
    Next
End Sub

Hope this helps

Not precisely. As MattP suggested, Directory.GetFiles has an overload that takes a search pattern. For example,

dim PDFfiles As String() = Directory.GetFiles(txtInput.Text, "*.pdf")

 

[Joshdbr]

OK, I got it

Thanks

 

[suju_26pro]

thnx ..i work on this code and do the required changes but i get error.......
wht is the problem....

 

[Joshdbr]

That would imply that the directory 'C:\Users\COD\Desktop\PDF Signer2\PDF Signer\bin\Debug\1' doesn't exist.

On a different note, here is the code snippet with using the Directory.GetFiles Overload:

Private Sub btnInput_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnInput.Click
    txtInput.Text = FolderBrowser1.ShowDialog
    If txtInput.Text.Length = 0 Then Exit Sub
    For Each File As String In Directory.GetFiles(txtInput.Text, "*.pdf")
        lstFiles.Items.Add(File)
    Next
End Sub

thx ..but still not working same error.............

 

[Joshdbr]

And that path exists? There is a folder name '1' in your debug folder?

 

[suju_26pro]

i didn't get u ,4 better underdstanding i just create a demo project using your code...but still it give me the same error......wht to do now...whn i selecte folder for input...it gives me the error...and whn i select the output folder '1' is display in outputtextbox...too confused now plz help me out...my proect subbmission date is comming ..plzz..

 

[Joshdbr]

Found the issue, sorry my fault, replace this line:

txtInput.Text = FolderBrowser1.ShowDialog

With this:

FolderBrowser1.ShowDialog()
If FolderBrowser1.SelectedPath = "" Then Exit Sub
txtInput.Text = FolderBrowser1.SelectedPath

You will want to change the same with the output folder.
