Steps to perform File System Control 1. Open VB application 2.To drag and drop the Directorylistbox,Drivelistbox,Filelistbox tools to our form 3.Add two button control and image controls. 4.image control used to display the user select images. 5.Run the application PROGRAM: Private Sub Drive1_Change() Dir1.Path = Drive1.Drive File1.Path = Dir1.Path End Sub Private Sub Dir1_Change() File1.Path = Dir1.Path End Sub Private Sub OK_Click() On Error Resume Next Image1.Picture = LoadPicture(Dir1.Path & "\" & File1.FileName) Label1.Caption = Drive1.Drive + Dir1.Path + "\" + File1.FileName End Sub Private Sub EXIT_Click() End End Sub OUTPUT:
