WPF and Winforms “airspace problem”: a solution

In a previous post, I talked about the “airspace problem”, an issue you can encounter when you are using WPF and WinForms in the same application. I created a small sample application that shows the issue and I’ve also added a possible solution.

If you run the application, you’ll see the following user interface:

This userinterface contains the following important elements:

  • A WPF Grid control that is not visible by default
  • A WPF button
  • A WindowsFormsHost control containing a usercontrol with a calendar control inside

When you click the button, the WPF Grid will be made visible. You see that the winformshost control is still shown on top of the grid(recognizable by the brown border on the left and the bottom.

Now try again but first select the Solve Airspace problem checkbox. This time the control is correctly shown on top of the winformshost.

Download the code and the sample application here.

A single pod produces about 11 Kg CO2eq per year( here the calculation). Reason enough to give it a try! Installing kube-green in your cluster The easiest way to install the operator in your cluster is through kubectl. We first need to install a cert-manager: kubectl apply -f https://github.com/cert-manager/cert-manager/releases/download/v1.14.5/cert-manager.yaml Remark: Wait a minute before you continue as it can take some time before the cert-manager is up & running inside your cluster. Now we can install the kube-green operator: kubectl apply -f https://github.com/kube-green/kube-green/releases/latest/download/kube-green.yaml Now in the namespace where we want t
