No answers in Forum to problem with CustomEvents

[irelandk]

There are 4-5 forum topics about the common problems with accessing the CustomEvents class. None of them seem answered to the satisfaction of the original post-er. I have a similar problem.

I have successfully compiled and run the original sample code. I am now trying to move toward developing my own site using the book concepts. I tried building a new site from scratch (in small steps) but had many problems. I am now trying the reverse: take the original working code and move away from it in small steps.

My first small step is to change the namespace used in the CustomEvents project. I changed the namespace in the CustomEvents file, changed the assembly name to isol.syn.CustomEvents, changed the root namespace to isol.syn and successfully rebuilt the project (under both Debug and Release). The isol.syn.CustomEvents.dll is now found under CustomEvents/bin and CustomEvents/obj for both debug and release.

I manually deleted the MB.TheBeerHouse.CustomEvents.dll files from the web bin folder. I removed references in the web project to MB.TheBeerHouse.CustomEvents and added a new reference to isol.syn.CustomEvents. I updated the web.config file eventmappings to type="isol.syn.WebCustomEvent, isol.syn.CustomEvents".

When I rebuild the solution, the isol.syn.CustomEvents.dll file is successfully copied to the web bin folder. However, I get an error message:

could not load type 'isol.syn.WebCustomEvent' from
assembly 'isol.syn.CustomEvents'.

I receive 13 related errors that 'type RecordDeletedEvent is not defined.'

Any thoughts on what I'm doing wrong?

Thanks!

You really need to open ildasm from a VS 2005 command prompt and then open that DLL to see what it has in it. This kind of problem can usually be fixed in about a minute.

You also need to ensure that the assembly is not in the GAC, or if it is there, it has to be the newest version (look in c:\windows\assembly).

You don't really need a reference to this DLL in the ASP.NET solution, but it won't hurt. This just copies it to the bin folder, or possibly makes an entry in web.config.

I prefer to keep web.config as clean as possible, and you get an automatic reference to all assemblies in the main bin folder.

By the way, the convention for parts of a namespace is to use Pascal case, since these are inherantly public. But it's just a convention and won't affect the operation of your site.

can u show me how to edit the web.config file in thebeershouse project without using the CustomEvents.dll and so on.

after replace the all the keyword thebeerhouse to Home. run in debug mode come out

Parser Error Message: Could not load file or assembly 'MB.Home.CustomEvents' or one of its dependencies. The system cannot find the file specified.

I don't know if this may be the case, but anyway:
Have you split your code into different projects? If so, have you signed the projects you are referencing? Some scenarios where you need to dynamically generate an instance of a given class (for instance, by using System.Activator.CreateInstance) require that:
a.) the class you wish to instantiate belongs to the same project you are trying to instantiate it in;
b.) you are using a fully qualified class name; or
c.) the project the desired class belongs to is signed.
Changing your namespaces' names doesn't make a difference here; splitting your code into different projects definitely does.
