Attempting to create a program that will find a folder in a directory based upon a wildcard search and result all files found to a listbox. I seem to be having some problems with it finding a folder that is like the input name from a textbox.
For a ridiculous example:
Textbox entry is "Cats and D"
Filename = "\Cats and Dogs Funnies\"
the file is filled with a bunch of great cat and dog pictures and videos (in separate sub folders) and I want to put the videos in a listbox as .fullname that is obtained when clicking a button
The hangup I seem to be having (besides being sloppy and somewhat new at this) is obtaining the found result that matches the wildcard' folder. Below is the stripped down version of my script. Any help would be greatly appreciated.
[ VB ]
Private Sub Button1_Click (sender As Object, e As EventArgs) Handles Button1.Click
Dim tbxCont, fipath As String
Dim di As System.IO.DirectoryInfo
Dim diar As System.IO.FileInfo
tbxCont = TextBox1.Text
fipath = "C:Users\RandomUser\Desktop\"
If txbCont = Nothing Then
MsgBox("Please provide a name",MsgBoxStyle.OkOnly)
Exit Sub
Else
If FileSystem.Dir(fipath & txbCont.Substring(0, txbCont.Length - 4) & "*", FileAttribute.Directory) <> "" Then
di = New System.IO.DirectoryInfo(fipath & txbCont.Substring(0, txbCont.Length - 4) & "*" & "\Videos\")
For Each diar In di.GetFiles("*", searchOption:=IO.SearchOption.AllDirectories)
FileList.Items.Add(diar.FullName)
Next
Exit Sub
End If
End Sub
It does not seem to be using the wildcard to find a like file. Is there a better way I could be going about this? Or, possibly obtain the found result from what has been found?
Much Thanks.
I assume that Filename = "\Cats and Dogs Funnies\" means DirectoryName= "Cats and Dogs Funnies".
You should first check whether the search pattern a user has provided can map to an existing Directory.
If it does not, inform that the partial path entered can't be found and return.
If it exists, add the "Videos" subfolder to the Path, list all the files this combined path contains and add the files FullName to a ListBox Control.
(Of course, some error handling is needed, first of all to verify that the a directory filter using wildcards is actually returning the desired results).
This is a possible solution:
If TextBox1.Text.Trim().Length = 0 Then
MsgBox("Please provide a name", MsgBoxStyle.OkOnly)
Exit Sub
End If
Dim txtCont As String = "*" & TextBox1.Text & "*"
Dim DirectoryBase As String = "C:\Users\RandomUser\Desktop\"
Dim DirInfo As DirectoryInfo = New DirectoryInfo(DirectoryBase)
Dim dInfoSearchFolder As DirectoryInfo =
DirInfo.GetDirectories(txtCont, SearchOption.AllDirectories).FirstOrDefault
If IsNothing(dInfoSearchFolder) Then
'Notify that the search path was not found
End If
dInfoSearchFolder = New DirectoryInfo(Path.Combine(dInfoSearchFolder.FullName, "Videos"))
FileList.Items.AddRange(dInfoSearchFolder.GetFiles().Select(Function(f) f.FullName).ToArray())
