Hi,
if the only reason you want to know is to avoid you add it again, then first remove it (this
does not harm if it was not there to begin with), hence:
event-=handler;
event+=handler;

Hi,
I am using an unmanaged DLL in my code and am running into problems because it is difficult to get the structures in the DLL to reset their state properly.
If I put the DLL in an AppDomain and unload the AppDomain, will that release the unmanaged DLL? That way, I could just start another AppDomain with the same DLL and have the state reset that way. This would be great, but I am not yet sure if it is possible.
Any help is appreciated.
Thanks,
klk

That sounds like a serious hack solution. I do not recommend doing that. You have not provided enough information about the situation for us to determine what else might be appropriate as a solution.

You need to explain that in detail otherwise we cannot understand the problem.

Hi led mike,
Basically, there is a possibility that the dll can be given wrong input, and as a result, can get into a state that is tough to recover from. The dll wasn't designed for this kind of input, but it is a small probability and I don't want the user's application to crash as a result. Thus, if I could simply blow away the AppDomain and bring it up again without the user ever knowing, that would be phenomenal.
Is this any clearer?
Thanks,
klk

Can you load a native DLL into an AppDomain? I don't believe so.
Do you have the DLL code?
It would work much better if the DLL is (or is a part of) a managed assembly.
If you have the code for the DLL, I would think proper error handling
in the DLL is a much better solution.
Otherwise, making the DLL a managed assembly will work fine, but you
may want to consider the implications - performance, marshaling across
the appdomain boundary, etc...

Yes. And if you don't have, and since it sounds like it's a pile of garbage, the next thing to consider is replacing it with your own code.

I have an web application ,i want to introduce touch screen in the application which is in .net framework.
I have no idea about how to integrate touch screen concept in the web application...
can any one help me please.
Hope you may help with logic to integrate.
Atleast give me the links where i can get information.
i think ,it's embedded related, i need some external hardware is what i think!!!
Anyway please help me out...
Thank you in advance...

I think that all u have to do is to plug the touch screen and start browsing. Nothing to add to the code unless u want to use some additional feature from the vendor's APIs.
Off course your controls should be larger to suit human fingers 
Hope this helps

Hi all.
I've searched around and can't find a solution to a pickle i'm in.
I'm writing a type of auto-complete selection process. I would like the box to highlight the
closest match as a user types in text.
Given a list of strings such as
R05
R09
R087
R321
R3394
G5832
If the user types in R09
String.Compare will return R05, R09, R087, R321, R3394
I want to find the string that has the largest match (In this case R09)
I could write a routine that does this, but didn't know if one exists in an assembly somewhere...
Anyone have any thoughts?
Thanks,
Tom

Youll have to write a custom method that does this using the String.StartsWith() method:
And, considering the example you gave, I feel you should process your textbox text in a loop that will do the following:
str.StartsWith("R09");
str.StartsWith("R0");
str.StartsWith("R");
So, the loop would decrement the index of the textbox string and check each time with - "R09","R0" and "R".

You may want to look for articles on "natural string comparison".

I'm having a little trouble trying to complete a fairly simple C# remoting app I found in a tutorial.
The server includes a declaration of an event-handler delegate the server class uses and the event argument class for the event. The client is then supposed to associate its event handler to the server's event (e.g., server.eventname += new eventhandlername(client.handler) ), periodically do things to raise the event, and finally remove its handler from the server's handler list when the client closes.
When I try to run the client, however, the server throws the following exception:
"An unhandled exception of type 'System.Security.SecurityException' occurred in mscorlib.dll
"Additional information: Type System.DelegateSerializationHolder and the types derived from it (such as System.DelegateSerializationHolder) are not permitted to be deserialized at this security level."
I'm reading this as some sort of a code access permissions problem, but so far I haven't been able to quite chase it down, much less figure out how to correct the problem. The event argument class definition in the server is marked as Serializable, but the event-handler delegate isn't; should it be? That doesn't seem right to me, but I'm obviously not getting something....
Thanks,
Ron Ritchie

I am not sure if this is the correct form, but as I think the problem is a result of something in .NET I am posting here.
Running a program (written in C# and using .NET 2.0) on a local machine. Using that program to access a file on a network drive, working on the file (the file is a SEGY file, like a JPEG, and lines are overlaid on the file, information about the lines get saved while the SEGY file is unchanged), and saving the work as a text file. It appears, depending on the size of the file trying to be written, the program hangs. A file of 900K can be written successfully, but when the program hangs it stops with about 230K written (working on a local machine only the save which hangs on a network drive works fine). Adding a flush after each write 'appears' to solve the problem (appearing to solve the problem isn't good enough). The writes are in a for loop, running in debug and adding a break point inside the loop, the break point is not tripped.
Has anyone had any experience with this or can they point me where I may be able to find an answer?
this thing looks like it was written by an epileptic ferret

I would like to know is there any release/build engineer related information is present here at CodeProject. I'm working as Technical support engineer and engaged into release of asp.net/sql server based files. I need to know any information/ group for this over here.

Click the Site Map link under NEWS & COMMUNITY. There is a Development Lifecycle category that has an Installation sub category that lists 93 articles. I have no idea what's in there but it sounds like thats what you want to look at, yes?

Hello everyone,
I am actually preparing for a job interview and I had my first telephone interview last week. One of the things that came up in the discussion was generation of .NET bytecode directly!
Well, I am not supposed to know how to go about it, I guess but it would be nice to talk about it intelligently in the interview. Does anyone know where I can get some information about it and if someone has tried doing something like that. It would definitely be nice to be able to suggest some ways one can go about it etc.
Many thanks,
Keith
