Here's the minimum amount of code required:
cboBox.Items.AddRange(System.IO.Directory.GetDirectories("D:\Directory"))
Alternatively, you may loop through the array returned by GetDirectories and add each item to the combobox's Items collection.
# 2 Re: Listing Directories in comboBox
works with ComboBox1.Items.AddRange(System.IO.Directory.GetDirectories("D:\"))
but not with
ComboBox1.Items.AddRange(System.IO.Directory.GetDirectories(Environment.CurrentDirectory))
# 3 Re: Listing Directories in comboBox
What is the value of Environment.CurrentDirectory?
# 4 Re: Listing Directories in comboBox
value of Environment.CurrentDirectory
D:\My Works\Windows Appl\WindowsApplication2\bin
but still it doesnt get
i did it by
textbox1.text=Environment.CurrentDirectory
# 5 Re: Listing Directories in comboBox
Are there any subdirectories under that folder? It works fine here.
# 6 Re: Listing Directories in comboBox
Oooooooooops their wasnt any folder .lol i just created & got it
As i wanted to display only the directory names io did this:
For i As Integer = 0 To folders.GetUpperBound(0) Step 1
'Remove the path.
folders(i) = IO.Path.GetFileName(folders(i))
Next i
now i got the directory names as combobox items
Actually I was building an aplicatin in which we can create a directory at runtime by entering the directory name
i wrote Application.StartupPath & "\" & & TextBox1.text
but while the directory is created the combo box which is on form1 does not displays it
& moreover if the directory already exists it gives Path/File access error

I am doing a similar project, and am having problems once I get the combobox populated with the data from a text file, you should be able to select one of the entries and it populate 3 textboxs. but I am having a problem with that part because no matter which item i select from the combobox it always displays the last entry.
here is the code that gets the information from the file.
Dim FileNum As Integer
FileNum = FreeFile()
FileOpen(FileNum, "f:\project2\project2.txt", OpenMode.Random, OpenAccess.Read, OpenShare.Shared, Len(udtProject2))
cmbUpDate.Text = "Select Record..."
Do
FileGet(FileNum, udtProject2)
cmbUpDate.Items.Add(udtProject2.strDirectory)
Loop Until EOF(FileNum)
FileClose(FileNum)
then in the combobox all i have for it is:
txtDirectoryName.Text = udtProject2.strDirectory
txtProjectPrefix.Text = udtProject2.strSubDirectory
txtProjectNumber.Text = udtProject2.strNumberofSub
but I think my problem is when I am getting the information.

You're setting the textboxes to the value of udtProject2, which is the last record you read from the text file. I recommend adding a .ToString function to your UDT that returns strDirectory:
Public Overrides Function ToString() As String
Return strDirectory
End Function
Then in your loop, add the entire UDT to the combobox:
cmbUpDate.Items.Add(udtProject2)
Finally, in the combo's SelectedIndexChanged event, cast the SelectedItem to a Project2 and set the textbox values:
Private Sub cmbUpDate_SelectedIndexChanged(ByVal sender As Object, _
ByVal e As System.EventArgs) Handles cmbUpDate.SelectedIndexChanged
Dim SelectedProject As Project2 = DirectCast(cmbUpDate.SelectedItem, Project2)
With SelectedProject
txtDirectoryName.Text = .strDirectory
txtProjectPrefix.Text = .strSubDirectory
txtProjectNumber.Text = .strNumberofSub
End With
End Sub
