Hello,
No problem, but:
I wouldn't want to see code like this in one of my projects.
If it makes sence to do this:
MarkPhB wrote: ( new AnyClass() ).SomeMethode();
,there is not need to use a class at all, I guess.
You could simply use a static method.
All the best,
Martin

Thanks for the answer =)
i use this sometimes when i have a class with have a methode that i need only one time. Like
( new Form1() ).ShowDialog() or
( new RNGCryptoServiceProvider() ).GetBytes( randomBytes );

Hi,
I don't like your ( new Form1() ).ShowDialog(); since Form1 (assuming
inheriting from Form) offers a Dispose() method which you should call once you don't
need the Form1 instance any longer.

Very Good point Luc!
I would use a "using" block for that!

I'm learning about IE Addon. I would like to know how to create the build-in object for IE. For example, "document" is the build-in object of IE and we can write the code like "document.getElementById() or document.write()" in Javascript. I wanna add "mydocument" object to Javascript engine of IE so that I can use the code like "mydocument.write()" in Javascript. I don't know how to do it and I googled about that but I didn't get any link for reference.. It would be great if anyone tell me how to do it or give me a link for reference..
Thanks in advance. Any idea would be appreciated.
Thanks and Regards,

Hi Michael,
Assuming you use the javascript engine from 'mshtml' interop.
MSScriptControl.ScriptControlClass.AddObject(string Name, object Object, bool AddMembers);
should do the work.
e.g.:
ScriptingEngine.AddObject("window", webBrowser.Document.Window.DomWindow, true);
ScriptingEngine.AddObject("document", webBrowser.Document.DomDocument, true);
Hope It helps

I've got to ask this. Why are you fishing for votes?
There are any number of people on the site now who are asking for votes so that they can become MVPs. Is this why you frequent the boards or is it to do something for others?
When I answer a question, I'm doing it to help others and give something back to CodeProject - if people vote, fine, if not, well that's fine as well. The only thing I would expect is that if I give a right answer, that the OP replies to let everybody else know that the answer was correct. In this way, other people who have the same issue can identify what worked without having to muck around trying things that didn't work. That's all that anybody can ask.

Okay. Pete. We already discussed about that once in this forum. In order to reply you the completed one, I was finding a lot of messages to get the one that we discussed..
#1. Why are you fishing for votes? Is this why you frequent the boards or is it to do something for others?
No and Yes.
Why "No"? I love to help other people. I used to participate in CodeProject and DevX forum whenever I have some free time.. ( here [^] is my profile in devx forum.) There is no MVP program in DevX forum.
So, I'm not coming here to become just a MVP.
Why "Yes"? I believe that it is good to become a MVP.. So, I don't mind if I become a MVP too..
#2. As I suggested here[^], the vote will help people to find the useful question and answer..
I wrote:
#2. Searching post by scores
I think that there are a lot of valuable posts in our forum. I wanna read those posts when I have free time. So, it is better if we can find those posts in easy way..
#3. Searching unanswered post by scores
At the same time, it would be great if we get the list unanswered posted based on scores (demand). We should encourage people to vote the question if it is good and useful.
#3. We already discussed about that earlier. (Please check this link[^] )
So, I want people to vote the message.. sometimes, people don't know to vote the message so I wrote about it in my signature to encourage people to vote the message.. I think that there are some people who feel the same way like me .. if you think that it is not necessary to write like that in your signature, it is okay. don't write this..
Thanks for asking.. because you give me a chance to explain why I'm coming here.
Let me know if you have any comment or suggestion..
Thanks and Regards,

Good answer.

Like it.
You could summarise this and include it in your sig rather than having something that looks like soliciting in.

Can you give me the sample to summarise this??
I'm thinking about that so long but I can't think of anything that doesn't look like soliciting in. I got very less vote since I have removed this from my signature..
Thanks in advance..

You could try something along the lines of:
"Please vote to let me (and others) know if this answer helped you or not. A 5 vote tells people that your question has been answered successfully and that I've pitched it at just the right level. Thanks."

No problem. Look forward to seeing it.

What is wrong with it? What is it supposed to do? What database system is it for? Why is this not in the SQL forum? What does this have to do with C#?
