Creating a basic C# Windows Forms application

This topic describes how to create a basic C# 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.cs > View Designer to open the Form1.cs [Design] page.
   2. Create a label Toolbox > 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 using clause for Qlik.Engine in the Form1.cs 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 version number from Qlik associative engine and update the label.

   private void Form1_Load(object sender, EventArgs e)
   {
       ILocation location = Qlik.Engine.Location.FromUri(new Uri("ws://127.0.0.1:4848"));
       location.AsDirectConnectionToPersonalEdition();
       using (IHub hub = location.Hub())
       {
           label1.Text = hub.QTProduct();
       }
   }
   				

   

4. Run the program.

   Steps

   1. Select Debug > Start Debugging.
   2. Ensure there is a compatible Qlik associative engine running. The version number of the engine is displayed.

   

You have now created a basic C# Windows Form application.
