I have a set of 2 ComboBoxes i would like to make Combobox 2 not populate from the directory if Combobox1 has a certain character in the file that is highlighted. If at all posible id like to find a way to have it continully search for the specific set of characters in combobox 1 and if the text falls within then combobox 2 will no longer populate
Heres the code im using to populate the Comboboxes
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim Files() As String = System.IO.Directory.GetFiles("I:\backuprouter\")
For Each s As String In System.IO.Directory.GetFiles("I:\backuprouter\")
ComboBox1A.Items.Add(IO.Path.GetFileName(s))
ComboBox2A.Items.Add(IO.Path.GetFileName(s))
Next
Dim fltr As New ArrayList
Dim fltr1 As New ArrayList
Dim opt As System.Text.RegularExpressions.RegexOptions = System.Text.RegularExpressions.RegexOptions.IgnoreCase
'Add all filenames starting with CE
For Each file As String In Files
Dim basename1 As String = My.Computer.FileSystem.GetFileInfo(file).Name
If System.Text.RegularExpressions.Regex.IsMatch(basename1, "^CE.*", opt) Then
fltr.Add(basename1)
End If
Next
ComboBox1B.DataSource = fltr
ComboBox1B.SelectedItem = Nothing
'Add all filenames starting with BE
For Each file As String In Files
Dim basename As String = My.Computer.FileSystem.GetFileInfo(file).Name
If System.Text.RegularExpressions.Regex.IsMatch(basename, "^BE.*", opt) Then
fltr1.Add(basename)
End If
Next
ComboBox2B.DataSource = fltr1
ComboBox2B.SelectedItem = Nothing
End Sub
Im really new at this but thanks for the help in advance!!!
