Creating a basic Visual Basic Windows Forms application

This topic describes how to create a basic Visual Basic Windows Forms application in Visual Studio.

Do the following:

1. Create a label (label1) to display the version of the Qlik associative engine.

   Steps

   1. Select Solution Explorer > Form1.vb > View Designer to open the Form1.cs [Design] page.
   2. Create a labelToolbox > Common controls > Label.
   3. Place the label on the Form1 component.

   

2. Create an event handler for the load event of the form.

   Steps

   1. Open the Properties panel for the Form1 object and click on the Events button.
   2. Double click on Load to add an event. The event (Form1_Load) is added and the code page is displayed.

   

3. Create a connection to the engine by adding a imports clause for Qlik.Engine in the Form1.vb file.

   Information noteThis example assumes that the engine is running locally because the hub is retrieved from Qlik.Engine.Location.FromUri.

   Then call QTProduct as a synchronous call to retrieve the engine edition from Qlik associative engine and update the label.

   Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
       Dim loc = Qlik.Engine.Location.FromUri(New Uri("ws://127.0.0.1:4848"))
       loc.AsDirectConnectionToPersonalEdition()
       Using hub As IHub = loc.Hub
           Label1.Text = hub.QTProduct
       End Using
   End Sub
   				

   

4. Run the program.

   Steps

   1. Select Debug > Start Debugging.
   2. Ensure there is a compatible Qlik associative engine running. The Qlik engine edition is displayed.

   

You have now created a basic Visual Basic Windows Form application.
