And the lmgify link was ever so helpful. Gosh, why didn't I think of that? #sarcasmimplied

I have used the levenshtein distance algorithm in my code before but it wasn't a part of SQL directly. I thought there may be an easier SQL call to search. I am mistaken.

Ah, SA, still being insulting to those with honest questions? I hope you don't respond to every wayward developer in this way. Calling someone naive and being demeaning isn't helpful. Obviously, I do believe someone with a friendly ear and a little patience would be able to help me or I wouldn't have posted my question here, as it has helped in the past. And since my level of SQL is somewhat limited, I wouldn't know if there was an easy solution or not now would I? It could be a simple SQL procedural call or even a basic where clause. That is why I asked. So instead of insulting an honest, if albeit "naive", question, maybe you could take the stance of trying to be helpful.

Oh, I see. It's amazing how deep the rabbit hole goes... lol

Do you have any other helpful posts or links about strongly named assemblies with digital signatures?

Now that isn't three in the morning, I may make more sense. I can put the everything but the plugin interface implementation in the host application. I can also pass the host mandatory interface by reference to the plugin but I am not sure how that would prevent someone from not replicating the host program since they will have the interface in the plugin. I understand that an official plugin will have a reference to the host plugin but can't that also be forged? Or have I completely missed your point. I am guessing I have.

Either way, thank you very much for the explanation!

OK so you are saying put the interface into my main app and then 3rd party developers will have to reference the main app to access the interface. If I understood that correctly, that is brilliant!

The part about the digital signature is confusing though. Can you explain that in more detail,step by step?

Thanks!

Ah, this helped a lot.

I am still confused why the prior solution (easy to refine my code) is a negative thing. Is it for security purposes or better control of code (thus less chance of breaking with rouge plugin.) If I need to redesign my plugin architecture that is fine, but I would prefer to know specifically why. :)

Please explain more. :)

Hey SA, is there a reason to not use Dave's method? It does work. I looked over your solutions and unfortunately, once again, they are over my head. I don't understand interfaces and assemblies, etc. If I create a plugin architecture that has a basic form to load and a few methods to return data, can you tell me the drawbacks?

My plugin is a simple form. It creates an assembly of the form and then does a showdialog() on run. I just need a title, description, and bitmap from the dll.

Lastly, if you could elaborate with specific code examples, that may help. :)

Thanks to both of you! :)

Ok, I was able to find and call a function. Question. Is there a way to directly invoke my function "Test" directly instead of for each'ing through the entire dll?

<pre lang="vb">
Dim assem As System.Reflection.Assembly =System.Reflection.Assembly.LoadFrom("myplugin.dll")
Dim ty As Type = assem.GetType("myPlugin.frmMain")
Dim class1 As Object = Activator.CreateInstance(ty)
Dim strMsg As String
Dim myMember() As System.Reflection.MethodInfo = class1.GetType.GetMethods()
For Each member As System.Reflection.MethodInfo In myMember
If member.Name = "Test" Then
strMsg = member.Invoke(Nothing, Nothing, Nothing, Nothing, Nothing)
Exit For
End If
Next</pre>

Oooh, I just realized the images are in a database, not on disk. That may change things with efficiency if it has to load them from the database (seek and retrieve time) instead of from disk.

Thank you, that is what I was thinking. Load the previous, the current, and the next screens (the 32 images). If the user scrolls to an uncached screen, say five screens down, it will have to load those from file. Still shouldn't take up too much. One question, what if a user scrolls multiple screens at a time? After the user is past the cache, each page will take a bit to load. Any idea on how to prevent that?

Thanks again!

I'm sorry but I do not think I am understanding it fully. Basically, you create a class wrapper that tracks the joystick. Then you create a separate thread that fires upon state change? I think I am partially getting the concept but I am still missing the implementation.

Not to be condescending but...

...huh? lol

Can you be a bit more specific? :)

But the numbers 01 (and 01) are unknown. I am using strMyString Like "A##B##" to see if it exists. Is there a way to use a wildcard with Regex.match?

Would:
output = Regex.Match(strMyString, @"A[0-9][0-9]B[0-9][0-9]").Value;
work?
