The problem has been resolved.
By the way, I couldn't use an interface, like all the normal examples on the net, because my plugin object has to inherit from another object and it has to have custom code in order for the plugins to work properly. This is why I could not use an interface.

Well you can inherit from some class and still implement another interface.

Or just get it working how I want it to work. Much less code, much better.

Let me make myself a bit more clear: I have 38 plugins already built, which implement this class. I worked a long time on them, and they are all working perfectly, so a complete redesign would make me have to strangle myself.
Turns out the problem was that I had two copies of the library containing the Plugin class being built. Although they were exactly the same, code-wise; maybe the version could of been different or something, resulting in the most irritating "Cannot convert from Plugin to Plugin" (I forget the proper syntax).
As a quick workaround I just popped the plugins libraries into the same directory as the exe, so they both reference the exact same Plugin library.

I know this one. In daily work it helps a lot to remove all '*' from the version in the 'AssemblyInfo.cs'.

hehe. Bad hey? The worst for me is when the registry data changes between debugs, and you think "why is it not working!???!".

Amazing! I clicked on the "Source Code" link at the site which took me to a page whose first link was CodeProject.
I think it's more efficient to just stay where I am.

What an utterly useless site!!
Every link I click on is obliterated by Google Ads.
Have I mentioned how much I hate Google Ads? They make your site look cheap and cluttered...

Hi ,
I have a problem with getting content of a word, excel ,pdf document to be displayed as a report. The path of the file is stored in the database (sql server 2000 in my case) . I want the to get the path and show the contents of the file as a report ...this because i don't want to allow users to modify the contents of the file...can this be done with crystal reports or any other tool?
My application is in VB.Net...
Please help me with any information about this...
Thanks in anticipation..

No, you cannot. However, I have developer a Viewer control which views any file type that the OS can view. This was mostly done by using a webbrowser control and hooking into different events. Now, it IS possible to handle specific events and get the type of object that is being loaded into the browser. Using this, you could write another layer to your code that can handle the multiple versions of MS Office which could stop a user from modifying a Document. For PDFs it doesn't really matter, only about 5% - 10% of employees actually have a full version of Acrobat where they could actually manipulate a PDF.
I cannot go into futher details because my code belongs to my company and I cannot distribute it. But the webbrowser will be your best bet. In .NET 2005, the webbrowser has been fully overhauled to be .NET friendly.

System.Diagnostics.PerformanceCounter class has access to all performance counters on NT based systems. Supports for CPU and memory usage and a lot more. Check it.

Hello:
I have used Omar Al Zabir's article Implement a Microsoft Word-like Object Model for Your .NET Framework Application[^] as the basis for several applications I have written now, partially because it made for a solid basis for developing Smart Client applications, but also as a means to learn some of the more advanced capabilities contained in the article Developing next generation Smart Clients using .NET 2.0 working with existing .NET 1.1 SOA based XML Web Services[^].
Where does one start when discussing this great framework? Everything about it is elegant, in addition to the fact that it provides a soup-to-nuts complete Enterprise application infrastructure including data access layer using .netTiers templates, a custom enhanced Business Layer facade, secure access to the services in the smart client, elegant implementation of the 'command' and 'mvc' patterns in the smart client, attractive user interface, etc.. That being said, as far as I can tell, the only competitor to this framework is the CompositeUI Application.
My question is this: Have any other developers evaluated both of these architectures, and if so, what reasons have you chosen to use CompositeUI or SmartInstitute?
|

Personally, I think the Composite UI App Block sucks! I've studied it intensely fro 6 months and MAYBE after about 6 months of studying, you MIGHT be able to put a project together. There is just way to much to grasp.
One of our requirements at my company is to make a Framework that all projects can be built from. I would NEVER base this framework off of the Composite UI! I would be training developers for years! I understand that MS must make App Blocks which work for all cases and all scenarios. However, most of their naming conventions and the way they've put things together could have been done so much better and cleaner!
One thing in particular is developing Plugins. If you use the Composite UI, not only will your Plugin need to know everything about the Host, but you Host also needs to know everything about your Plugin!!!  Decoupled model my a$$!

Before you think this is just another "How do I...?" please read. I DO NOT need to know how to do async operations. Here's my scenario...
I am performing Async callbacks on a Form to retrieve data on a seperate thread. I am using Delegates not Threads. First, I am not simply calling one Query and Oh, we're done. I kick off about 7 different delegates to load data from different sources. I am using "SyncLocks" or "lock" in C# with different Lock objects per data I am retrieving. One thing that is happening now is that users are CLOSING my form while data is still loading. Obviously, this causes numerous errors because the Callbacks do not have a UI thread to go back to.
My question is, how can I cancel an Async operation or gracefully exit running one?
|

Since executing a delegate asynchronously means that the target method executes on a thread from the CLR's thread pool, you will not have fine-grain control over the worker thread. If you need the ability to manipulate the worker thread you should explicitly create it.

Hi,
My apllication gives error when I try to open the oledb connection. "CreateActCtxW could not be located in the dynamic link library KERNEL32". This windows app is running on windows server 2000. But if I run on my client machine on Win XP, it runs fine. I am using com object for excel 9.0.
Can anyone please help ??
Thanks a lot!
|
|
|
|
|
Is the com object for excel 9.0 registered on the 2000 machine?
|
|
|
|
|
Yes, I belive so, otherwise I should have got the error that excel not registered error. I am using the COM interop for excel, Interop.Excel.dll
How do I find out if the COM is registered.
Thanks!!

I should have asked the question a little better. Is Excel installed on the windows 2000 server? If not this is your problem. If so what version? My guess is that the version's are different and the COM compenents support different methods.
I had this problem once a long time ago with VB6 and different versions of office installed on the clients machines, but I cannot remember the specific error message

Thanks for your reply, I will look into the version.
