I don't want to take away from anything that you have already achieved but StringBuilder is probably not a good idea here. Plain concatenation is almost certain to be faster for a small number of operations (up to about half a dozen). StringBuilder only wins when you're doing lots of concatenations to the same string or if the original string is very long (don't ask me to define 'very long'; you would need to experiment).

I do lots of concatenations to the same string over and over, namely whenever new mail data arrives, which happens quite a few times in a second.

With simple concatenation it took my client almost 5 Minutes to receive about 2mb of mail data, with StringBuilder it's 5 seconds now! Smile | :)

I only use StringBuilder when I need to concatenate a string over and over again multiple times.

OK. My comment was based on the code you show, which only does a single two-character concatenation.

First of all, if this isn't homework, I can't imagine what you'd need this for. Therefore, you need to do your own homework.

Secondly, saying 'I need it urgently' is plain rude - people on this forum will help you of their own free will, they are not beholden to you in any way, nor can you demand a time frame. Try to do your own homework, ask some specific questions when you're stuck, and we'll try to help, when we can.

You might want to reply to the original poster, not Christian. I don't think he needs to be told how not to post his "homework" questions.

cannot find out if the threads in the default System.Threading.ThreadPool have ended.

To do this, you can roll your own like Ami Bar[^] does in this article[^].

fire a parent control events from its childs events

Hi friends
In my c# project I have a Main form with a panel1 on it and a user control named Thumbs in the solution ,
The panel1 hosting instances of thumbs as its child controls .the problem is that when mouse clicks on the
child controls of panel1 the Panel1_click event not fires but this works when the mouse locates between
the thumbs (gap erea) , so the question would be How is possible to fire a parent control event(here panel1)
from its child controls(here thumbs) events?
Please If some of you knows ho to get trough let me know with some code if possible.

thanks.
M.Jaf

You can subscribe the Panel to the child Thumbs' Click event. Then, when the Thumb get clicked, the Panel will know about it and you can call its OnClick method.

Note, to do this, you'll need to subclass Panel.

Hi! I need to display math equations in C# application. Unfortunately, seems like Microsoft Equation editor files (EXE and DLL) are not COM components, so i can't add it in VS controls toolbox. Does anyone have idea how to acomplish this?

Any other idea (not using Microsoft Equation)?

Thanks in advance!

DataAccessors

Ive got a problem. i have made a classlibrary with dataclasses and a classlibary with data-accessorclasses (in which i use sqlqueries to get data from an sqldatabase). i try to import these classes in a webservice.
When i type "using DataClasses" (the dataclasses library), there isno problem at all.
But when i type "using DataAccessors" it doesnt recognises it. I've added the references, so that's not the problem. I also tried changing the name, but thats no problem either...
Any ideas?

Thx, Peter
