Hi,

I am working on a program which must be used to install/uninstall some software. I am using ManagementObject together with a ManagementOperationObserver in order to update a progressbar. Everything works unless updating the progressbar.

Is there anybody who has experience with this feauture?

re: Uninstalling a software with C#

I am not making an .MSI installer.

The software, my program must install/uninstall is Uniprint, Adobe Reader, and Citrix. My problem is that, when I get notification from my observer, and I try to update the progressbar, everything stucks. The progress event should - according to its specification - also tell me how many procent of the process is gone/left but context and Uppebound is always 0!

Here you go:

Expand|Select|Wrap|Line Numbers
  1. internal static void Progress(object Sender, System.Management.ProgressEventArgs Args)                    
  2. {
  3.       // Tell the form to update its progressbar
  4.        _Owner.ProgressChangedDelegate(Sender, _Owner, Args);
  5. }
  6.  
  7. internal static void Completed(object Sender, System.Management.CompletedEventArgs Args)
  8. {       
  9.        _Owner.ProgressCompletedDelegate(Sender, _Owner, Args);
  10. }
  11.  
  12. ………..
  13. ………..
  14.  
  15.  
  16. private string Uninstall(string Path)
  17. {
  18.    ManagementObject Product = new ManagementObject(Path);
  19.    System.Management.ManagementOperationObserver WMIObserver;
  20.  
  21.    WMIObserver = new System.Management.ManagementOperationObserver();
  22.  
  23.    WMIObserver.Completed += new System.Management.CompletedEventHandler(Completed);
  24.    WMIObserver.Progress += new System.Management.ProgressEventHandler(Progress);
  25.  
  26.    Product.InvokeMethod(WMIObserver, "Uninstall", null);                        
  27.  
  28.    …

re: Uninstalling a software with C#

TIP: When you are writing your question, there is a button on the tool bar that wraps the [code] tags around your copy/pasted code. It helps a bunch. Its the button with a '#' on it. More on tags. They're cool. Check'em out.
