Sir please reply me now if my posts here is correct.And please post me a message or example of correct format of code that can be post here.
Because I can`t move on in my program code in C sharp because of some errors I did recently here.
-
Okay, If you are the one by deleting my duplicated posts here.That`s good.And I`m very thankful for that sir!! And how it is sir that until now I don`t have received a answer for the question I posted here?? :-\
-
And how it is sir that until now I don`t have received a answer for the question I posted here?? :-\
You asked this question before, and received a very pertinent answer.
-
Because I`m really don`t know how to delete my duplicated posts here!! :)
-
I meant, you asked, before, "How is it that until now I haven't received an answer?". You asked this
Sir I am waiting from then that my asked question in the date of Oct.04,2010, 4:26A.M.About my C# questions.And hoping to be answered.So now it is no replied messages in my inbox.So how it is Sir like that??and hoping to you sir more power!!
The answer is "because nobody posted an answer". There is no guarantee that every question will be answered, and it is foolish to complain if you do not get one. In fact, doing this may make people who know how to help you decide not to post.
-
Sir I`m very thankful for that answer.It`s because I`m really don`t know who is answering my questions here and I think there are working in this site and paid it to assigned for answering a questions here about software programming.
And sir can you help me to delete my question here that is my program code in c sharp and a question in above of that code.Because that questions I asked there is very unclear and lack of grammar to be understand by the members here. ::)

Sir thank you for this answer.It`s because I`m really don`t know who is answering my questions here and I think there are working in this site and paid it to assigned for answering a questions here about software programming. :)
Nobody is paid here, any answers you might get are from other members like yourself, who may or may not know the answers you need, and are free to answer or not. If people were paid, where did you think the money comes from? Did you pay any money to join or ask questions?
-
Because I`m really new or I am a beginner to asked a questions in forum like this and I have no other forums like this that are the answer is right away or in the same day..And I feel comfortable for this site.. :)

Because that questions I asked there is very unclear and lack of grammar to be understand by the members here. ::)
That's somewhat true, but I understood enough to know exactly what the problem was, I believe. Your code contains both of the routines that you say you don't have. So I think it follows from that that you have both the button and the code but you cannot "link" them together; that is, you've messed about with them enough that the event has gotten decoupled from the UI element. (this usually happens when you change the name of the procedure).
I also know that if you had read the Programmers guide at all, especially regarding the help for the Visual Studio UI, you would know exactly what do do. You can either use the Properties window to quickly re-link the events back together with their functions or you could even do something really crazy like double-click on the relevant buttons, at which point new Click Event procedures are generated, and use Copy-Paste to move the code from the old decoupled procedure to the new one.
The former is quite a lot easier.
This is one thing that I personally find rather annoying. nowadays, having a firm grasp of a programming language isn't enough to develop applications in the long-term, since nowadays we have to work with designers. One should make an effort to learn the User-interface and conventions of said environment for the creation of your UI elements, and "connecting" those UI elements with the appropriate code. To be clear, it's not annoying that people that are first learning it have trouble with problems that require UI elements tof the environment that are right in front of their face, it's when people post a question on the forum about it and seemingly stop trying to solve the problem themselves. It's been almost a week since you posted this. You would expect maybe a glance or two at the Visual Studio Programmers guide; specifically, the information on the Properties (http://msdn.microsoft.com/en-us/library/ms171352%28v=VS.90%29.aspx) window.
That was why I didn't answer. Both the solution as well as how to find it are neither obscure nor difficult to discover. It's a lack of initiative to blame here, a tendency to "oh, I hit a roadblock- I give up" and then post on a forum, wait a week, and essentially complain that nobody responded.

But sir there are no definite answer if there are really experienced to solve any problems about programs in c sharp in this forum,am I right???And maybe myself only or my friend programmer could answer my questions someday about my calcultator program?? :-\

And maybe myself only or my friend programmer could answer my questions someday about my calcultator program?? :-\
I just gave you two answers to your problem.
-
And sir I have a duplicated posts again here.So can I please you sir to delete that again.Please!!! :)
-
Please!

thank you3x sir!!!
