Creating Install for Services
in [Dot Net]
|
From: Israel on 30 May 2008 15:40 I found it surprisingly unintuitive and difficult to get the installation code to work properly and I found very little help on the google groups so I figured Id post the things that burned me so someone else doesnt have to work through the same issues. I created a service using the wizard and then I added an Installer class. On the canvas of the installer class I plopped down an instance of a ServiceInstaller and a ServerProcessInstaller. After I thought I had everything set up correctly I tried running InstallUtil.exe on my service exe. Problem #1: I got the following error: System.BadImageFormatException: The format of the file 'SnapshotAnalyzer.exe' is invalid I come to find out that somehow the .NET 1.1 was in my path BEFORE the .NET 2.0 path (for whatever reason). I got rid of the .NET 1.1 from my path. Problem #2: I got the following error: System.InvalidOperationException: Installation failed due to the absence of a ServiceProcessInstaller. The ServiceProcessInstaller must either be the containing installer, or it must be present in the Installers collection on the same installer as the ServiceInstaller. What I hadnt realized is that the ServiceInstaller automatically had its parent set to the Installer class but the ServiceProcessInstaller did not so I had to manually set its parent property. Problem #3: I got the following error: System.ArgumentException: Must specify value for source. I hadnt set the ServiceName on the ServiceInstaller instance. I guess somehow Im supposed to know that source and ServiceName are really the same thing? Also I found this article useful for making a service able to install/ uninstall itself without the use of installutil.exe. In addition allow the service to run as a normal process so you can debug it: http://www.eggheadcafe.com/articles/20060104.asp The example is in Visual Studio 2003 but its easy enough to modify it if you just add some public methods on the service class that just call OnStart() and OnStop().
From: Phil Wilson on 31 May 2008 20:41 Nobody who works with fully-featured installation tools uses installer classes to install services. MSI has built-in support to do it "for free" and pretty much all the tools *except* Visual Studio have IDE support to populate the ServiceInstall and ServiceControl tables that have been in Windows Installer since before .NET came along. A further irony is that the Windows Installer team doesn't even support the managed code installer classes used by Visual Studio to install services. http://robmensching.com/blog/archive/2007/04/19/Managed-Code-CustomActions-no-support-on-the-way-and-heres.aspx -- Phil Wilson "Israel" <israeldiperi(a)hotmail.com> wrote in message news:a417c2d4-7384-4c3e-b21e-6b96e239ceb8(a)79g2000hsk.googlegroups.com...
