Browsing for a folder


We have seen how to browse a folder using the File Management codeunit. Unfortunately, we do not have any function that will help us to browse folders. To overcome this, we will use automation control that should be already installed on your Windows.

How to do it...

  1. Create a new codeunit from Object Designer.

  2. Add the following global variables:

    Name

    Type

    Subtype

    Length

    MSShell

    Automation

    'Microsoft Shell Controls

    And Automation'.Shell

     

    Folder

    Automation

    'Microsoft Shell Controls

    And Automation'.Folder3

     

    FilesInFolder

    Automation

    'Microsoft Shell Controls

    And Automation'.

    FolderItems3

     

    CurrentFile

    Automation

    'Microsoft Shell Controls

    And Automation'.

    FolderItem2

     

    SelectedFolder

    Text

  3. Write the following code in the OnRun trigger of the codeunit:

    CREATE(MSShell, FALSE, TRUE);
    Folder := MSShell.BrowseForFolder(0, 'NAV Folder Browser', 0);
    FilesInFolder := Folder.Items();
    CurrentFile := FilesInFolder.Item();
    SelectedFolder...
