mike few programmers here are just so stupid that they just waste time pulling each other legs. They need a life....Anyway do not take it personally....Just ignore them and move on. May be they are so proud of what they know. Just share it guys if you know and it doesn't matter if the problem is simple or complex. At least this guy is putting effort into it... Yeh mike just remember you have to put 95% of the effort yourself. Spoon feeding is not acceptable here atleast in this forum. All the best.

kinda i am using visual C# not the console one the one were you can place buttons and stuff they are similiar but different i cant test this till i am at school tomorrow when it returns where does it go to? this seems to help tho thanks alot if it just leaves the whole if statement that would be great
the code which i posted can work in both console and windows.. dont confuse with Debug.Writeline satement, it is just used to print in Output Window. ie.
private void button1_Click(object sender, EventArgs e) { int x = 5; if (x == 5) { Debug.WriteLine("more code to runs here1"); Debug.WriteLine("more code to runs here2"); if(done) return; // This will exit the funtion button1_Click else { Debug.WriteLine("more code to runs here3"); Debug.WriteLine("more code to runs here4"); Debug.WriteLine("more code to runs here5"); } } Debug.WriteLine("more code to runs here6"); Debug.WriteLine("more code to runs here7"); Debug.WriteLine("more code to runs here8"); }the return statement will exit from the funtion button1_Click.

Return is not allowed inside of methods more than once and should not be used by any method that does not have a functional result. Doing so is a poor programming practice that violates the one-in, one-out principle.
Yeah, that's what I thought also until I read Implementation Patterns by Kent Beck: Back in the old days of programming, a commandment was issued: each routine shall have a single entry and a single exit. This was to prevent the confusion possible when jumping into and out of many locations in the same routine. It made good sense when applied to FORTRAN or assembly language programs written with lots of global data where even understanding which statements were executed was hard work. In Java, with small methods and mostly local data, it is needlessly conservative. However, this bit of programming folklore, thoughtlessly obeyed, prevents the use of guard clauses. Guard clauses are particularly useful when there are multiple conditions: [Code example snipped of nested if statements with a single return] Nested conditionals breed defects. The guard clause version of the same code notes the prerequisites to processing a request without complex control structures: [Code example snipped of flat if statements each with a return ] Keep in mind there is more context to his segment on the Guard Clause. If you are interested I highly recommend the book.
All truth passes through three stages. First, it is ridiculed. Second, it is violently opposed. Third, it is accepted as being self-evident.
Arthur Schopenhauer - German philosopher (1788 - 1860)
Unfortunately, the nature of business software development causes me to recommend against this. Using structured exists simplifies debugging and serves as a preventative measure from a junior programmer going haywire with a 10 page method. While I can say a deeply nested conditional does breed defects the case is made to follow Fowler on this one and refactor into more simpler methods.

Return is not allowed
Not allowed, or not recommended? Two different things. I don't know of any language that places a restriction on the number of return statements that can be used in a block of code. However, yes, good design principles dictate that you should have as few exit points as possible. The original question only asked what the equivalent of VB's exit sub was, not how it should be used. Both Mike and I answered that direct question. Saying "Don't listen to anyone else" is a bit over the top.

Anyone with the experience and judgment to disregard my statement would do so. Telling a novice not to do it is perfectly inline. A lot of the advice I give is structured to introductory programmers as more experienced developers have the experience to know when it is hogwash. By biasing my response towards less experienced developers I increase the value of the statements. I will repeat my statement with the inferred subtext: "Return is not allowed unless you have the experience and judgment to properly identify cases for its use and understand the consequences both positive and negative"

http://mansoftdev.com/Resume/Mark%20Nischalke.doc[^] i believe i found that guys problem... he seems to be upset most likely because he has no people skills and by the looks of it cant seem to hold down a job... maybe just me but maybe no one else seems to like him, idk just throwing that out there

thanks for that it is really hard to explain what i mean tho, i know about that but since it is a timer once it is executed it will set off all of the others that is what i want it to do but i want to go through one if statement each time the timer is used. i am making a program with a group of 16 buttons and when they click one it changes the colors of those around it and i want to send out a wave effect so the only practical way i could think of was finding something similiar to that break thing other wise all of them will go off i just dont really know how to explain what i need thanks for the help tho
It sounds like you need to rethink your logic a bit. The requirements you just spelled out shouldn't require such a complex

Wow, you found my resume online. I'm impressed and awed by your skills. I see that not only are you an experienced developer, but also a psychologist. So tell me Dr., why do I hate my mother? Speaking of mothers, I think yours is calling. It's past your bedtime anyway, so run along little one.

haha for a "big mature adult" which for whatever you seem to think you are, you behave much more imaturely than my little sister, i cant explain y you hate your mother but probably because you are a failure to what you truly want to be have average skills and think that towering over younger people and imposing your measly imaginitive power deep down inside this makes you feel better and people liek you need to grow up and are just dispicable.
