I am using Wix 3.7. I am trying to create wix burn bootstrapper that install my msi. I have added two buttons in my BA UI for Install and Cancel. i am using C# for BA UI design.
I have added the follwoing code in Install button for launch installation.
MySampleBA.Model.Engine.Detect();
MySampleBA.hwnd = IntPtr.Zero;
MySampleBA.Model.Bootstrapper.PlanBegin += this.PlanBegin;
MySampleBA.Model.Bootstrapper.DetectPackageComplete += this.DetectedPackage;
MySampleBA.Model.Bootstrapper.DetectComplete += this.DetectComplete;
MySampleBA.Model.Bootstrapper.PlanPackageBegin += this.PlanPackageBegin;
MySampleBA.Model.Bootstrapper.PlanComplete += this.PlanComplete;
MySampleBA.Model.Bootstrapper.ExecuteMsiMessage += this.ExecuteMsiMessage;
MySampleBA.Model.Bootstrapper.ExecuteProgress += this.ApplyExecuteProgress;
MySampleBA.Model.Bootstrapper.PlanMsiFeature += this.PlanMsiFeature;
MySampleBA.Model.Bootstrapper.PlanPackageComplete += this.PlanPackageComplete;
MySampleBA.Model.Bootstrapper.Progress += this.ApplyProgress;
MySampleBA.Model.Bootstrapper.CacheAcquireProgress += this.CacheAcquireProgress;
MySampleBA.Model.Bootstrapper.CacheComplete += this.CacheComplete;
MySampleBA.Model.Bootstrapper.Error += this.ExecuteError;
MySampleBA.Model.Bootstrapper.ExecutePackageComplete += this.ExecuteComplte;
and launch install by using
MySampleBA.Model.Engine.Plan(LaunchAction.Install);
MySampleBA.Model.Engine.Apply(MySampleBA.hwnd);
The installation is working fine. But i have a problem with cancel the installation at mid.
I saw bootstrapper application rollback link. But i can't able to get an idea about IDCANCEL and How to trigger the Error event from button click.
Can anyone tell how to stop the installation by clicking cancel button which is in BA UI in detail?
Many of the callbacks (like
Progress
) will provide args (likeProgressEventArgs
) to your bootstrapper application. In the args object you may see aResult
property. To cancel, set theResult
property toResult.Cancel
. When the callback returns to theBurn
engine, it will see you set the result to cancel and start the rollback process (or do whatever cancel means in that context).
