What do you mean with 'pointer in C# windows form'?
I mean if you are asking about C# pointer types, they have nothing to do with Windows Forms.

Solution 1

Pointers are discouraged in C#: they are available, but only when you change your project to permit unsafe code and also use the unsafe keyword: http://msdn.microsoft.com/en-us/library/chfa2zb8.aspx[^]

There is a tutorial here: http://msdn.microsoft.com/en-us/library/aa288474(v=vs.71).aspx[^] on unsafe code, but to be honest, if you are trying to use it and you don;t know what you are doing, then you have probably got the design of your project wrong. You should only need pointers when dealing with external code not written in C# (and most of the time, not even then) or when you need serious performance in a small chunk of code. In both cases, if you don't already know how to use this, you probably shouldn't need to do it at all.

please, remove the answer sir as i have changed the question.

OriginalGriff 23-Jan-14 6:00am

No - because your question now makes even less sense than it did...what the heck are you actually trying to achieve? Do you know what a pointer is? If not, what are you using the term, and what are you actually trying to do?
(And why do you think that boolean values should have a "Checked" property?)

agent_kruger 23-Jan-14 6:12am

no sir, actually i cannot post the code and to ask the question had to make that example up.

OriginalGriff 23-Jan-14 6:36am

Then you can't expect us to answer the question unless you give us a description which matches what you are actually trying to do! :laugh:

So, talk to me: what are you trying to do? What are you trying to achieve (and forget the word "pointer" for the moment)

i want to use a pointer that is defined in different scope and called in different scope.

OriginalGriff 24-Jan-14 1:46am

Your code does not use pointers: so forget the word completely, and try to explain what you are trying to do without using it.
Just reiterating the same thing again and again doors not help us to understand what you are trying to do if we have already told you that we do not know what you are trying to do!

sir, i have only posted the question to know that "if a declared variable in one scope can be used in another scope or not"?

Solution 2

Sending 'pointer' to (1) is 'pointless' :-).

Even if technically feasible, since the C# programming language features the goto statement, it would be one of the very bad ways to use the latter.

You could accomplish the same effect (if it makes sense) adding the statement

chk3.Checked == false;

just below (or just above ) the

Quote:
//from here the pointer should goto (1) statement

line.

CPallini 23-Jan-14 6:25am

That's not feasible in C# (no lognjmp, sorry!) and you should possibly re-design the (probably poor) code.

agent_kruger 22-Feb-14 23:18pm

sir, that's not the code just a concept i want to learn.

agent_kruger 21-May-14 11:28am

sir, there is no need for me to re-designing as i have only posted the question to know that "if a declared variable in one scope can be used in another scope or not"?
