Calling C# functions from a button onclick event
I would start by putting your code in the code behind instead of embedding it in the page. If you do embed it in the page then I think you need to specify the language as C#. In addition to that, your code doesn't look like it will work, and if you modify it so it will, you will be open to a SQL Injection attack. I recommend the following steps: Move your click event to the code behind Read up on Parameterized Queries Your method for accessing the textbox seems unnecessarily complex as well. Is there a reason you are using FindControl instead of just using the control's name?

Calling multiple functions on form submit?
Because you never return false! function validateform() { var validation = true; <-- set to true if ((emailmatch() && checkFirstname() && checkLastname && checkgender())== true) return validation; <--- returns true <-- if false you do not return anything } Either add a return false, or change it to a return with all the checks. function validateform () { return emailmatch() && checkFirstname() && checkLastname && checkgender(); } After you get that straight, you have to realize that an empty string is not null.

single canvas element calling multiple functions sequentially
It is definetly possible this way, you just need to provide your canvas.width and canvas.height. If you are looking for an alternative way of drawing circles, arcs, rectangles in a more simple way check out create.js. It has built in functions for drawCircle and other shapes. It also supports a redraw functions for the context. All the best!

Script calling multiple other scripts erroring due to undefined functions
The problem is execfile. Basically, execfile is a fancy exec with a file. So when you call execfile 'secondary.py' Python executes all the lines of secondary.py in the context of where execfile was called. Which, in this case, is inside the callscripts function. What you probably want is subprocess.

a single click-event for multiple functions
Maybe something like this: $('#picture-div ,#picture-div2').click(function(){ if($(this).attr("id") == '#picture-div') $('#div-in-document').fadeToggle('slow', $func); else $('#div-in-document2').fadeToggle('slow', $func2); }); Or you can make a kind of mapping: var arr = [ { selector: "#picture-div", subselector: "#div-in-document", func: $func1}, { selector: "#picture-div2", subselector: "#div-in-document2", func: $func2}] and go through it for assigning handler: for(int i = 0; i < arr.length; i++) { $(arr[i].selector).click(function(){ $(arr[i].subselector).fadeToggle('slow', arr[i].func); }); }

What is the proper way to declare javascript prototype functions calling helper functions
I prefer method 3, declaring it as a property of the constructor: function HeavilyInstantiated() {} HeavilyInstantiated.helper = function(param) { return compute(param); } HeavilyInstantiated.prototype.computeHard = function(params) { var someResult = HeavilyInstantiated.helper(params.prop1); return someResult; } You still have only one instance of the helper method, but it doesn't pollute the global namespace or the instances of HeavilyInstantiated (it is not on their prototype chain).

Calling functions inside functions when the inner function's arguments will always be the same as the outer's
I honestly think your first technique is the best way to go and perfectly idiomatic. Still, here's another option: def outer_method(word) inner_lambda = lambda do puts "I really love " + word + "!" end inner_lambda.call puts word + " tastes like candy." end outer_method("onions") lambda creates a lexical closure, which means it captures the surrounding environment, including the reference to word.

Calling functions inside other functions in Python
def topx(x): print x*top + '+' This takes one argument: x. But when you call it: def block(f,g,*args): f(*args) # This is what calls topx g(*args) You're passing it *args, which contains [x, 4, midx, x]. And that's four arguments right there. You should probably reconsider your structure to fix this. Perhaps a class?

Calling functions from threads
First of all you have a compilation error because you're trying to reference the variable th as a field on an object of type Demo. th is not a field, but rather a local variable and can be referenced directly (i.e. without the o. prefix). Second, sum() and diff() cannot be called against an instance of Thread as those methods are not defined by thread, but rather by your own Demo class. All that being said, these compilation problems aren't even the root issue for this code. Based on your code it seems you have some fundamental misunderstandings about the syntax and structure of Java programs so it might benefit you to go through some entry-level tutorials before trying to tackle concurrent programming. But, for the sake of completeness here is a brief explanation of what you need to do i

Javascript Bug calling functions
You just need to wait for DOM to get loaded fully. Because you dont seem to be using jQuery, you need to do it the classic JavaScript way. Here is the documentation to get you started . As a side note: this becomes very easy, if you use jQuery. Please ask if you need help on how to do this using jQuery. UPDATE: The jQueryWay First include jQuery on your page. Remove onClick events from your html. To both your js files add this code and change the function name: $(function() { $("#myimage").click(function() { changeImage(); }); }); Do this for both yor javascript files and change the imageID and function call accordingly. '#myimage' is the id of your image that you bind the click callback to. This is doing exactly the same thing that you were, except completl

Calling Different Functions tkinter
You are retrieving the text of the Entry before the mainloop. Instead of that, you should check the content inside the callback function: def callback(event): text = inputfield.get() if 'weather:' in text: weather() if 'open:' in text: program() # ... inputfield.bind('<Return>', callback) Besides, if you bind two times the <Return>event, the second binding will override the previous one (unless you pass "+" as the third argument). However, with only one callback you have enough to control both scenarios.

My guess is your Scanner classes are interfering with each other. exercise1 takes input from standard in then closes when it's done. Then exercise2 also tries to get input from standard in which is closed. I would suggest you only make 1 Scanner and pass it as a parameter to both exercise1 and exercise2 and then close it after both calls.

calling an child form event replacing or avoiding the mdi parent form event
This approach detects WM_NCHITTEST message sent to your MainGridControl before MdiChildActivate is fired. This can only detect if your mouse is used (Click, DoubleClick) on the MainGridControl but I think it suits in your case. public class Form1 : Form { public Form1(){ InitializeComponent(); Load += (s,e) => { gridProc.AssignHandle(MainGridControl.Handle); }; } MainGridProc gridProc = new MainGridProc(); private void MDIMain_MdiChildActivate(object sender, EventArgs e) { if(gridProc.HitTestOn) { gridProc.HitTestOn = false; return; } //code is still run if HitTestOn = false //....... } public class MainGridProc : NativeWindow { protected override void WndProc(ref Message m){ if(m.Msg == 0x84)//WM_NC

Will calling async functions within different functions still cause async behavior?
Will each ajax/async function's call be certain to execute in the order of their parent functions? They should execute in order, but their internal callbacks can be called in any order. If not, is there a good (hopefully simple?) alternative to having a long chain of callbacks? You could use a promise, and execute the next function when the promise has been resolved. This example uses jQuery... var fn1 = function () { var d = $.Deferred(); setTimeout(function () { $("body").text("Callback 1 done.") && d.resolve(); }, Math.random() * 1300 + 800); return d.promise(); }; var fn2 = function () { var d = $.Deferred(); setTimeout(function () { $("body").text("Callback 2 done.") && d.resolve(); }, 500); return d.promise

Calling functions from section 2 of the manual in C++
I'm curious if C++ libraries now have a more C++ way to access these functions w/o having to include a lot of C header files? They don't, since those functions are provided by POSIX and not a feature of the language. What is provided, however, are iostream abstractions (C++98, chapter 27) which do much of the common functionality of the "section 2" open()/close()/read()/write() calls. C++11 provides yet more abstractions which cover more of the functionality provided by the POSIX, Windows (etc) APIs.

To do this in PL/pgSQL, use the PERFORM statement so it's just do $$ PERFORM my_function(); $$;

Calling functions with variables that may not be defined
First of all this is not an error but a notice so you could disable it. Secondly you can define this parameter as being passed by reference to avoid the notice. error_reporting(E_ALL); function x(&$a) { var_dump('inside', $a); return empty($a) ? "null" : "'$a'"; } $a = 4; var_dump('before', isset($a), isset($c)); $b = x($a); $d = x($c); var_dump('after', isset($a), isset($c)); var_dump($b, $d); output: string(6) "before" bool(true) bool(false) string(6) "inside" int(4) string(6) "inside" NULL string(5) "after" bool(true) bool(false) string(3) "'4'" string(4) "null"

Calling javascript functions from drop down with php variables
A couple of points: The value of term is "1", "2", "3" or "" respectively, not the text between the option begin and end tags. That is why changing it to = worked, as then the condition evaluates to true. Your function doesn't need to return anything. However, you might want to replace its call with sOutput(text); return false or some equivalent to prevent the form from submitting. A minor point, but the id and name of select should be the same. You pass text as an object to the function, but a neater way would be to pass the id "text", and retrieve e1 the same way as term, by using document.getElementById. The first two points should be enough to make it all work though, depending on how finicky your browser is.

Are deferred functions called when calling log.Fatalln?
No, the deferred functions aren't run. Here's the description of log.Fatal : Fatal is equivalent to Print() followed by a call to os.Exit(1). log.Fatal calls os.Exit, whose description is here : Exit causes the current program to exit with the given status code. Conventionally, code zero indicates success, non-zero an error. The program terminates immediately; deferred functions are not run. Demonstration If you really need to properly close resources or do some tasks before the program finishes, then don't use log.Fatal.

Calling functions inside JavaScript 'for' loops
one possible problem is for(i=0; i<50; i++){ here i is a global variable if inside any one of the function(where i is again in global scope) is value is changed to > 50 then the loop will get terminated they both references the same instance in the global scope. Try for( var i=0; i<50; i++){ instead. When you use var in a variable declaration, that variable will be created in the local scope(the function in which it is declared)

Calling functions by passing interface type
http://docs.oracle.com/javase/tutorial/java/javaOO/methods.html All java objects descend from Object. You defined the interface Side Head implements Side Tail implements Side. You have four methods with the same name (overload), but which all have different signatures... one accepts a Head, another a Tail, another a Side, and the last an Object. Since both Head and Tail inherit from Side, the method overload(Side side) will accept either as an argument. Similarly, since both Head and Tail descend from Object, overload(Object obj) will accept either. In your specific example, firstAttempt is of type Side, so when you invoke overload(firstAttempt), you are using the overload(Side side) method. Your second invocation explicitly casts to Object, so you are using overload(Object obj). Yo

functions in javascript - defining and calling them, with or without a function name
Clicking alert_five will not work since you have overwritten the function with a variable. notice that: function alert_five(){ alert('five'); } console.log(alert_five) //prints function alert_five(){ alert('five'); } You then assign alert_five to something else, the returned value of return_five() the function and since it doesn't return anything it is undefined. var alert_five = alert_five(); console.log(alert_five) //prints undefined Between bracktes you pass value so when you call function .click(function_name()) you call the function and pass the value that is returned by it. Some functions take other function as parameter so you have to pass them as function_name

Calling external c++ template functions within Cython
Cython supports template syntax but only for classes (as of Cython 0.19.1). Although you can wrap template functions using the following syntax: # doublit.pxd file cdef extern from "doublit.h": cdef int doublit1 "doublit<int>"(int& foo) cdef double doublit2 "doublit<double>"(double& foo) # main.pyx file from doublit cimport * cdef int n1 = 5 cdef double n2 = 5.0 print(doublit1(n1)) print(doublit2(n2)) You lose the automation, but at least you can make it work. UPDATE Cython 0.20 adds support for calling C++ template functions. Cython 0.20 beta release announced.

Passing and assigning functions versus calling them
Neither. The function doesn't return anything, therefore assigning its return value won't do anything. Similarly, just assigning the function itself to the variable doesn't do anything either. In the case of setTimeout, you should NEVER pass a string. You can either pass a function directly (myFunction) and it will be called, or you can pass an anonymous function (which makes it easier to pass arguments) such as setTimeout(function() {doSomething(123);},1000);
