Why would you want to use unmanaged code? One reason could be because you may set the starting folder!
You can still use the ShBrowseForFolder Win32 API call if you are ready to use unmanaged code. What if I really want to use unmanaged code? This will change the description in the resulting dialog, the startup location (set to the Desktop instead of M圜omputer) and also a textbox will appear just over the buttons. ObjFB.Description = "Type your own description" If you select one folder and click the OK button, the selected path will be displayed into a message box (because this is what we are doing with the Path property).ĭo you remember that we have added properties to our class?īefore calling the ShowBrowser method, we could have used them like this: You can run the project now and you should see the dialog to the right appear after you have clicked the button. With four lines of code, you have a working folder browser! If objFB.ShowBrowser = DialogResult.OK Then Double-click on it to create the Click handler procedure.
It is now the time to count them!Īdd a button to the form that is already created in your project. When we started the wrapper class, I told you that the use of the class should take about 5 lines of code. Style = CType(Me.Style, FolderNameEditor.FolderBrowserStyles)ĭim dlgResult As DialogResult =. StartLocation = CType(Me.StartLocation, FolderNameEditor.FolderBrowserFolder) The last thing we need in this class is a method that will actually display the dialog and return a dialog result and set the path property: Public ReadOnly Property Path() As String The read-only Path property will be used to retrieve the selected folder. The Description property can be used to change the message that will appear in dialog (near the top). Now add two public properties to our class. Private mstrPath As String = String.Empty Private mstrDescription As String = "Please select a directory below:" Let's now add some private members to the class (and one of them is of the FolderBrowser type that comes from the FolderNameEditor namespace): Public Style As enuFolderBrowserStyles = enuFolderBrowserStyles.ShowTextBox Public StartLocation As enuFolderBrowserFolder = enuFolderBrowserFolder.BrowseForComputer Now we can create two public class members from the enumeration (and we also give a default value): ShowTextBox = FolderBrowserStyles.ShowTextBox RestrictToSubfolders = FolderBrowserStyles.RestrictToSubfolders RestrictToFilesystem = FolderBrowserStyles.RestrictToFilesystem RestrictToDomain = FolderBrowserStyles.RestrictToDomain 'The FolderBrowserStyles collection is a member of FolderNameEditorīrowseForComputer = FolderBrowserStyles.BrowseForComputerīrowseForEverything = FolderBrowserStyles.BrowseForEverythingīrowseForPrinter = FolderBrowserStyles.BrowseForPrinter Templates = FolderBrowserFolder.Templates StartMenu = FolderBrowserFolder.StartMenu NetworkNeighborhood = FolderBrowserFolder.NetworkNeighborhood NetAndDialUpConnections = FolderBrowserFolder.NetAndDialUpConnections MyPictures = FolderBrowserFolder.MyPictures MyDocuments = FolderBrowserFolder.MyDocuments M圜omputer = FolderBrowserFolder.M圜omputer We also need to recreate two enumerations that change the behavior of the dialog box:įavorites = FolderBrowserFolder.Favorites As I have said earlier, we inherit an existing class.

The following code is going into the class (between the Public Class. Before the "Public Class MyFolderBrowser", we need to import the Design namespace using this line: Be sure that the Class template is selected and change the name to MyFolderBrowser.vb. Select "Add Class." from the Project menu. About 5 lines will be required to use the feature. This wrapper will ease the re-use of this feature. We will create a class that wraps the functionality of the folder browser. Net tab) and click the Select button and then the OK button. From the "Add Reference" dialog, choose "" (in the. Select "Add Reference." from the Project menu. Since this project inherits an existing class, we need to add a reference.
