Pfft! Microseconds! Never solve a problem in microseconds that can be solved in nanoseconds.

Note that the accepted answer:

• iterates over the whole data, regardless of whether a nan is found
• creates a temporary array of size N, which is redundant.

A better solution is to return True immediately when NAN is found:

import numba
import numpy as np

NAN = float("nan")

@numba.njit(nogil=True)
def _any_nans(a):
    for x in a:
        if np.isnan(x): return True
    return False

@numba.jit
def any_nans(a):
    if not a.dtype.kind=='f': return False
    return _any_nans(a.flat)

array1M = np.random.rand(1000000)
assert any_nans(array1M)==False
%timeit any_nans(array1M)  # 573us

array1M[0] = NAN
assert any_nans(array1M)==True
%timeit any_nans(array1M)  # 774ns  (!nanoseconds)

and works for n-dimensions:

array1M_nd = array1M.reshape((len(array1M)/2, 2))
assert any_nans(array1M_nd)==True
%timeit any_nans(array1M_nd)  # 774ns

Compare this to the numpy native solution:

def any_nans(a):
    if not a.dtype.kind=='f': return False
    return np.isnan(a).any()

array1M = np.random.rand(1000000)
assert any_nans(array1M)==False
%timeit any_nans(array1M)  # 456us

array1M[0] = NAN
assert any_nans(array1M)==True
%timeit any_nans(array1M)  # 470us

%timeit np.isnan(array1M).any()  # 532us

The early-exit method is 3 orders or magnitude speedup (in some cases). Not too shabby for a simple annotation.

Try the following:

CONVERT(VARCHAR(10),GetDate(),102)

Then you would need to replace the "." with "-".

Here is a site that helps http://www.mssqltips.com/tip.asp?tip=1145

As in your example, the fit_start_time is not later than the fit_end_time.

Try it the other way round:

var fit_start_time  = $("#fit_start_time").val(); //2013-09-5
var fit_end_time    = $("#fit_end_time").val(); //2013-09-10

if(Date.parse(fit_start_time) <= Date.parse(fit_end_time)){
    alert("Please select a different End Date.");
}

Update

Your code implies that you want to see the alert with the current variables you have. If this is the case then the above code is correct. If you're intention (as per the implication of the alert message) is to make sure their fit_start_time variable is a date that is before the fit_end_time, then your original code is fine, but the data you're getting from the jQuery .val() methods is not parsing correctly. It would help if you gave us the actual HTML which the selector is sniffing at.

Accepted answer can also be written in following way using arrow function on .some

 function checkAndAdd(name) {
     var id = arr.length + 1;
     var found = arr.some((el) => {
           return el.username === name;
     });
     if (!found) { arr.push({ id: id, username: name }); }
 }

Easy solution - copy from excel and paste into google sheets. It copies all of your reference cells as absolute cells so you can begin from scratch. Then sort and download back as an excel grid and reformat to your needs.

(I've made a gist of all the code in this answer in case you want to play with it)

I have only ever did most basic things in asm during my CS101 course back in 2003. And I had never really "got it" how asm and stack work until I've realized that it's all basicaly like programming in C or C++ ... but without local variables, parameters and functions. Probably doesn't sound easy yet :) Let me show you (for x86 asm with Intel syntax).

1. What is the stack

Stack is usually a contiguous chunk of memory allocated for every thread before they start. You can store there whatever you want. In C++ terms (code snippet #1):

const int STACK_CAPACITY = 1000;
thread_local int stack[STACK_CAPACITY];

2. Stack's top and bottom

In principle, you could store values in random cells of stack array (snippet #2.1):

stack[333] = 123;
stack[517] = 456;
stack[555] = stack[333] + stack[517];

But imagine how hard would it be to remember which cells of stack are already in use and wich ones are "free". That's why we store new values on the stack next to each other.

One weird thing about (x86) asm's stack is that you add things there starting with the last index and move to lower indexes: stack[999], then stack[998] and so on (snippet #2.2):

stack[999] = 123;
stack[998] = 456;
stack[997] = stack[999] + stack[998];

And still (caution, you're gonna be confused now) the "official" name for stack[999] is bottom of the stack.
The last used cell (stack[997] in the example above) is called top of the stack (see Where the top of the stack is on x86).

3. Stack pointer (SP)

For the purpose of this discussion let's assume CPU registers are represented as global variables (see General-Purpose Registers).

int AX, BX, SP, BP, ...;
int main(){...}

There is special CPU register (SP) that tracks the top of the stack. SP is a pointer (holds a memory address like 0xAAAABBCC). But for the purposes of this post I'll use it as an array index (0, 1, 2, ...).

When a thread starts, SP == STACK_CAPACITY and then the program and OS modify it as needed. The rule is you can't write to stack cells beyond stack's top and any index less then SP is invalid and unsafe (because of system interrupts), so you first decrement SP and then write a value to the newly allocated cell.

When you want to push several values in the stack in a row, you can reserve space for all of them upfront (snippet #3):

SP -= 3;
stack[999] = 12;
stack[998] = 34;
stack[997] = stack[999] + stack[998];

Note. Now you can see why allocation on the stack is so fast - it's just a single register decrement.

4. Local variables

Let's take a look at this simplistic function (snippet #4.1):

int triple(int a) {
    int result = a * 3;
    return result;
}

and rewrite it without using of local variable (snippet #4.2):

int triple_noLocals(int a) {
    SP -= 1; // move pointer to unused cell, where we can store what we need
    stack[SP] = a * 3;
    return stack[SP];
}

and see how it is being called (snippet #4.3):

// SP == 1000
someVar = triple_noLocals(11);
// now SP == 999, but we don't need the value at stack[999] anymore
// and we will move the stack index back, so we can reuse this cell later
SP += 1; // SP == 1000 again

5. Push / pop

Addition of a new element on the top of the stack is such a frequent operation, that CPUs have a special instruction for that, push. We'll implent it like this (snippet 5.1):

void push(int value) {
    --SP;
    stack[SP] = value;
}

Likewise, taking the top element of the stack (snippet 5.2):

void pop(int& result) {
    result = stack[SP];
    ++SP; // note that `pop` decreases stack's size
}

Common usage pattern for push/pop is temporarily saving some value. Say, we have something useful in variable myVar and for some reason we need to do calculations which will overwrite it (snippet 5.3):

int myVar = ...;
push(myVar); // SP == 999
myVar += 10;
... // do something with new value in myVar
pop(myVar); // restore original value, SP == 1000

6. Function parameters

Now let's pass parameters using stack (snippet #6):

int triple_noL_noParams() { // `a` is at index 999, SP == 999
    SP -= 1; // SP == 998, stack[SP + 1] == a
    stack[SP] = stack[SP + 1] * 3;
    return stack[SP];
}

int main(){
    push(11); // SP == 999
    assert(triple(11) == triple_noL_noParams());
    SP += 2; // cleanup 1 local and 1 parameter
}

7. return statement

Let's return value in AX register (snippet #7):

void triple_noL_noP_noReturn() { // `a` at 998, SP == 998
    SP -= 1; // SP == 997

    stack[SP] = stack[SP + 1] * 3;
    AX = stack[SP];

    SP += 1; // finally we can cleanup locals right in the function body, SP == 998
}

void main(){
    ... // some code
    push(AX); // save AX in case there is something useful there, SP == 999
    push(11); // SP == 998
    triple_noL_noP_noReturn();
    assert(triple(11) == AX);
    SP += 1; // cleanup param
             // locals were cleaned up in the function body, so we don't need to do it here
    pop(AX); // restore AX
    ...
}

8. Stack base pointer (BP) (also known as frame pointer) and stack frame

Lets take more "advanced" function and rewrite it in our asm-like C++ (snippet #8.1):

int myAlgo(int a, int b) {
    int t1 = a * 3;
    int t2 = b * 3;
    return t1 - t2;
}

void myAlgo_noLPR() { // `a` at 997, `b` at 998, old AX at 999, SP == 997
    SP -= 2; // SP == 995

    stack[SP + 1] = stack[SP + 2] * 3; 
    stack[SP]     = stack[SP + 3] * 3;
    AX = stack[SP + 1] - stack[SP];

    SP += 2; // cleanup locals, SP == 997
}

int main(){
    push(AX); // SP == 999
    push(22); // SP == 998
    push(11); // SP == 997
    myAlgo_noLPR();
    assert(myAlgo(11, 22) == AX);
    SP += 2;
    pop(AX);
}

Now imagine we decided to introduce new local variable to store result there before returning, as we do in tripple (snippet #4.1). The body of the function will be (snippet #8.2):

SP -= 3; // SP == 994
stack[SP + 2] = stack[SP + 3] * 3; 
stack[SP + 1] = stack[SP + 4] * 3;
stack[SP]     = stack[SP + 2] - stack[SP + 1];
AX = stack[SP];
SP += 3;

You see, we had to update every single reference to function parameters and local variables. To avoid that, we need an anchor index, which doesn't change when the stack grows.

We will create the anchor right upon function entry (before we allocate space for locals) by saving current top (value of SP) into BP register. Snippet #8.3:

void myAlgo_noLPR_withAnchor() { // `a` at 997, `b` at 998, SP == 997
    push(BP);   // save old BP, SP == 996
    BP = SP;    // create anchor, stack[BP] == old value of BP, now BP == 996
    SP -= 2;    // SP == 994

    stack[BP - 1] = stack[BP + 1] * 3;
    stack[BP - 2] = stack[BP + 2] * 3;
    AX = stack[BP - 1] - stack[BP - 2];

    SP = BP;    // cleanup locals, SP == 996
    pop(BP);    // SP == 997
}

The slice of stack, wich belongs to and is in full control of the function is called function's stack frame. E.g. myAlgo_noLPR_withAnchor's stack frame is stack[996 .. 994] (both idexes inclusive).
Frame starts at function's BP (after we've updated it inside function) and lasts until the next stack frame. So the parameters on the stack are part of the caller's stack frame (see note 8a).

Notes:
8a. Wikipedia says otherwise about parameters, but here I adhere to Intel software developer's manual, see vol. 1, section 6.2.4.1 Stack-Frame Base Pointer and Figure 6-2 in section 6.3.2 Far CALL and RET Operation. Function's parameters and stack frame are part of function's activation record (see The gen on function perilogues).
8b. positive offsets from BP point to function parameters and negative offsets point to local variables. That's pretty handy for debugging
8c. stack[BP] stores the address of the previous stack frame, stack[stack[BP]] stores pre-previous stack frame and so on. Following this chain, you can discover frames of all the functions in the programm, which didn't return yet. This is how debuggers show you call stack
8d. the first 3 instructions of myAlgo_noLPR_withAnchor, where we setup the frame (save old BP, update BP, reserve space for locals) are called function prologue

9. Calling conventions

In snippet 8.1 we've pushed parameters for myAlgo from right to left and returned result in AX. We could as well pass params left to right and return in BX. Or pass params in BX and CX and return in AX. Obviously, caller (main()) and called function must agree where and in which order all this stuff is stored.

Calling convention is a set of rules on how parameters are passed and result is returned.

In the code above we've used cdecl calling convention:

• Parameters are passed on the stack, with the first argument at the lowest address on the stack at the time of the call (pushed last <...>). The caller is responsible for popping parameters back off the stack after the call.
• the return value is placed in AX
• EBP and ESP must be preserved by the callee (myAlgo_noLPR_withAnchor function in our case), such that the caller (main function) can rely on those registers not having been changed by a call.
• All other registers (EAX, <...>) may be freely modified by the callee; if a caller wishes to preserve a value before and after the function call, it must save the value elsewhere (we do this with AX)

10. Function calls

Now the most interesting part. Just like data, executable code is also stored in memory (completely unrelated to memory for stack) and every instruction has an address.
When not commanded otherwise, CPU executes instructions one after another, in the order they are stored in memory. But we can command CPU to "jump" to another location in memory and execute instructions from there on. In asm it can be any address, and in more high-level languages like C++ you can only jump to addresses marked by labels (there are workarounds but they are not pretty, to say the least).

Let's take this function (snippet #10.1):

int myAlgo_withCalls(int a, int b) {
    int t1 = triple(a);
    int t2 = triple(b);
    return t1 - t2;
}

And instead of calling tripple C++ way, do the following:

1. copy tripple's code to the beginning of myAlgo body
2. at myAlgo entry jump over tripple's code with goto
3. when we need to execute tripple's code, save on the stack address of the code line just after tripple call, so we can return here later and continue execution (PUSH_ADDRESS macro below)
4. jump to the address of the 1st line (tripple function) and execute it to the end (3. and 4. together are CALL macro)
5. at the end of the tripple (after we've cleaned up locals), take return address from the top of the stack and jump there (RET macro)

Because there is no easy way to jump to particular code address in C++, we will use labels to mark places of jumps. I won't go into detail how macros below work, just believe me they do what I say they do (snippet #10.2):

// pushes the address of the code at label's location on the stack
// NOTE1: this gonna work only with 32-bit compiler (so that pointer is 32-bit and fits in int)
// NOTE2: __asm block is specific for Visual C++. In GCC use https://gcc.gnu.org/onlinedocs/gcc/Labels-as-Values.html
#define PUSH_ADDRESS(labelName) {               \
    void* tmpPointer;                           \
    __asm{ mov [tmpPointer], offset labelName } \
    push(reinterpret_cast<int>(tmpPointer));    \
}

// why we need indirection, read https://stackoverflow.com/a/13301627/264047
#define TOKENPASTE(x, y) x ## y
#define TOKENPASTE2(x, y) TOKENPASTE(x, y)

// generates token (not a string) we will use as label name. 
// Example: LABEL_NAME(155) will generate token `lbl_155`
#define LABEL_NAME(num) TOKENPASTE2(lbl_, num)

#define CALL_IMPL(funcLabelName, callId)    \
    PUSH_ADDRESS(LABEL_NAME(callId));       \
    goto funcLabelName;                     \
    LABEL_NAME(callId) :

// saves return address on the stack and jumps to label `funcLabelName`
#define CALL(funcLabelName) CALL_IMPL(funcLabelName, __LINE__)

// takes address at the top of stack and jump there
#define RET() {                                         \
    int tmpInt;                                         \
    pop(tmpInt);                                        \

    push(22);
    push(11);
    push(7777); // dummy value, so that offsets inside function are like we've pushed return address
    myAlgo_asm();
    assert(myAlgo_withCalls(11, 22) == AX);
    SP += 1; // pop dummy "return address"
    SP += 2;
    pop(AX);
}

Notes:
10a. because return address is stored on the stack, in principle we can change it. This is how stack smashing attack works
10b. the last 3 instructions at the "end" of triple_label (cleanup locals, restore old BP, return) are called function's epilogue

11. Assembly

Now let's look at real asm for myAlgo_withCalls. To do that in Visual Studio:

• set build platform to x86 (not x86_64)
• build type: Debug
• set break point somewhere inside myAlgo_withCalls
• run, and when execution stops at break point press Ctrl + Alt + D

One difference with our asm-like C++ is that asm's stack operate on bytes instead of ints. So to reserve space for one int, SP will be decremented by 4 bytes.
Here we go (snippet #11.1, line numbers in comments are from the gist):

;   114: int myAlgo_withCalls(int a, int b) {
 push        ebp        ; create stack frame 
 mov         ebp,esp  
; return address at (ebp + 4), `a` at (ebp + 8), `b` at (ebp + 12)
 
 sub         esp,0D8h   ; reserve space for locals. Compiler can reserve more bytes then needed. 0D8h is hexadecimal == 216 decimal 
 
 push        ebx        ; cdecl requires to save all these registers
 push        esi  
 push        edi  
 
 ; fill all the space for local variables (from (ebp-0D8h) to (ebp)) with value 0CCCCCCCCh repeated 36h times (36h * 4 == 0D8h)
 ; see https://stackoverflow.com/q/3818856/264047
 ; I guess that's for ease of debugging, so that stack is filled with recognizable values
 ; 0CCCCCCCCh in binary is 110011001100...
 lea         edi,[ebp-0D8h]     
 mov         ecx,36h    
 mov         eax,0CCCCCCCCh  
 rep stos    dword ptr es:[edi]  
 
;   115:    int t1 = triple(a);
 mov         eax,dword ptr [ebp+8]   ; push parameter `a` on the stack
 push        eax  
 
 call        triple (01A13E8h)  
 add         esp,4                   ; clean up param 
 mov         dword ptr [ebp-8],eax   ; copy result from eax to `t1`
 
;   116:    int t2 = triple(b);
 mov         eax,dword ptr [ebp+0Ch] ; push `b` (0Ch == 12)
 push        eax  
 
 call        triple (01A13E8h)  
 add         esp,4  
 mov         dword ptr [ebp-14h],eax ; t2 = eax
 
 mov         eax,dword ptr [ebp-8]   ; calculate and store result in eax
 sub         eax,dword ptr [ebp-14h]  

 pop         edi  ; restore registers
 pop         esi  
 pop         ebx  
 
 add         esp,0D8h  ; check we didn't mess up esp or ebp. this is only for debug builds
 cmp         ebp,esp  
 call        __RTC_CheckEsp (01A116Dh)  
 
 mov         esp,ebp  ; destroy frame
 pop         ebp  
 ret  

And asm for tripple (snippet #11.2):

 push        ebp  
 mov         ebp,esp  
 sub         esp,0CCh  
 push        ebx  
 push        esi  
 push        edi  
 lea         edi,[ebp-0CCh]  
 mov         ecx,33h  
 mov         eax,0CCCCCCCCh  
 rep stos    dword ptr es:[edi]  
 imul        eax,dword ptr [ebp+8],3  
 mov         dword ptr [ebp-8],eax  
 mov         eax,dword ptr [ebp-8]  
 pop         edi  
 pop         esi  
 pop         ebx  
 mov         esp,ebp  
 pop         ebp  
 ret

I would recommend using prototype's callback.isFunction().

They've figured out the difference and you can count on their reason.

I guess other JS frameworks have such things, too.

instanceOf wouldn't work on functions defined in other windows, I believe. Their Function is different than your window.Function.

Internet Explorer (IE8 and lower) doesn't support addEventListener(...). It has its own event model using the attachEvent method. You could use some code like this:

var element = document.getElementById('container');
if (document.addEventListener){
    element .addEventListener('copy', beforeCopy, false); 
} else if (el.attachEvent){
    element .attachEvent('oncopy', beforeCopy);
}

Though I recommend avoiding writing your own event handling wrapper and instead use a JavaScript framework (such as jQuery, Dojo, MooTools, YUI, Prototype, etc) and avoid having to create the fix for this on your own.

By the way, the third argument in the W3C model of events has to do with the difference between bubbling and capturing events. In almost every situation you'll want to handle events as they bubble, not when they're captured. It is useful when using event delegation on things like "focus" events for text boxes, which don't bubble.

As explained in the C++ Core Guidelines C.49: Prefer initialization to assignment in constructors it prevents unnecessary calls to default constructors.

strftime("%Y");

I love strftime. It's a great function for grabbing/recombining chunks of dates/times.

Plus it respects locale settings which the date function doesn't do.

irb(main):001:0> a = 1
=> 1
irb(main):002:0> a ||= 2
=> 1

Because a was already set to 1

irb(main):003:0> a = nil
=> nil
irb(main):004:0> a ||= 2
=> 2

Because a was nil

It is a duplicate of this question, with an answer that contains a time measurement of the different methods.

Conclusion: Use [void] or > $null.

Hex:

printf("64bit: %llp", 0xffffffffffffffff);

Output:

64bit: FFFFFFFFFFFFFFFF

The final keyword is used to declare constants.

final int FILE_TYPE = 3;

The finally keyword is used in a try catch statement to specify a block of code to execute regardless of thrown exceptions.

try
{
  //stuff
}
catch(Exception e)
{
  //do stuff
}
finally
{
  //this is always run
}

And finally (haha), finalize im not entirely sure is a keyword, but there is a finalize() function in the Object class.

Jean-François Fabre set.intesection(*list_of_sets) answer is definetly the most Pyhtonic and is rightly the accepted answer.

For those that want to use reduce, the following will also work:

reduce(set.intersection, list_of_sets)

You have to run 'bibtex':

latex paper.tex

      $filename= time()."pdf"; 
    //$filelocation = "C://xampp/htdocs/Nilesh/Projects/mkGroup/admin/PDF";

     $filelocation = "/pdf uplaod path/";
     $fileNL = $filelocation."/".$filename;

       $pdf->Output($fileNL,'F');
       $pdf->Output($filename, 'S');

Try this ,

<img src= "@Url.Content(Model.ImagePath)" alt="Sample Image" style="height:50px;width:100px;"/>

(or)

<img src="~/Content/img/@Url.Content(model =>model.ImagePath)" style="height:50px;width:100px;"/>

ConcurrentLinkedQueue

If you don't care about having index-based access and just want the insertion-order-preserving characteristics of a List, you could consider a java.util.concurrent.ConcurrentLinkedQueue. Since it implements Iterable, once you've finished adding all the items, you can loop over the contents using the enhanced for syntax:

Queue<String> globalQueue = new ConcurrentLinkedQueue<String>();

//Multiple threads can safely call globalQueue.add()...

for (String href : globalQueue) {
    //do something with href
}

That you can handle the checked and unchecked events seperately doesn't mean you have to. If you don't want to follow the MVVM pattern you can simply attach the same handler to both events and you have your change signal:

<CheckBox Checked="CheckBoxChanged" Unchecked="CheckBoxChanged"/>

and in Code-behind;

private void CheckBoxChanged(object sender, RoutedEventArgs e)
{
  MessageBox.Show("Eureka, it changed!");
}

Please note that WPF strongly encourages the MVVM pattern utilizing INotifyPropertyChanged and/or DependencyProperties for a reason. This is something that works, not something I would like to encourage as good programming habit.

I had to add the follow lines to my windows path to fix this. CMAKE should set the correct paths on install otherwise as long as you check the box. This is likely to be a different solution depending on the myriad of versions that are possible to install.

This confused me for a while until I worked out that the dependencies of the various projects in the solution had been messed up. Get that straight and naturally your assembly appears in the right place.

I use it in a practical sense when we transfer large binary objects (images) via web services. So when I am testing a C# web service using a python script, the binary object can be recreated with a little magic.

I resolved this issue by creating a file called .user.ini in the directory where the PHP file scripts reside (this means any PHP script in this directory gets the new file size limit)

The contents of .user.ini were:

upload_max_filesize = 40M
post_max_size = 40M

With the release of Android 2.3 (Gingerbread), you can now use the android.hardware.Camera class to get the number of cameras, information about a specific camera, and get a reference to a specific Camera. Check out the new Camera APIs here.

There are many ways. A rather simple solution is to use a 2D vector.

#include <algorithm>
#include <iostream>
#include <vector>
using namespace std;

int main() {
 vector<vector<double>> val_and_id;
 val_and_id.resize(5);
 for (int i = 0; i < 5; i++) {
   val_and_id[i].resize(2); // one to store value, the other for index.
 }
 // Store value in dimension 1, and index in the other:
 // say values are 5,4,7,1,3.
 val_and_id[0][0] = 5.0;
 val_and_id[1][0] = 4.0;
 val_and_id[2][0] = 7.0;
 val_and_id[3][0] = 1.0;
 val_and_id[4][0] = 3.0;

 val_and_id[0][1] = 0.0;
 val_and_id[1][1] = 1.0;
 val_and_id[2][1] = 2.0;
 val_and_id[3][1] = 3.0;
 val_and_id[4][1] = 4.0;

 sort(val_and_id.begin(), val_and_id.end());
 // display them:
 cout << "Index \t" << "Value \n";
 for (int i = 0; i < 5; i++) {
  cout << val_and_id[i][1] << "\t" << val_and_id[i][0] << "\n";
 }
 return 0;
}

Here is the output:

   Index   Value
   3       1
   4       3
   1       4
   0       5
   2       7

This is more of an example where TABLOCK did not work for me and TABLOCKX did.

I have 2 sessions, that both use the default (READ COMMITTED) isolation level:

Session 1 is an explicit transaction that will copy data from a linked server to a set of tables in a database, and takes a few seconds to run. [Example, it deletes Questions] Session 2 is an insert statement, that simply inserts rows into a table that Session 1 doesn't make changes to. [Example, it inserts Answers].

(In practice there are multiple sessions inserting multiple records into the table, simultaneously, while Session 1 is running its transaction).

Session 1 has to query the table Session 2 inserts into because it can't delete records that depend on entries that were added by Session 2. [Example: Delete questions that have not been answered].

So, while Session 1 is executing and Session 2 tries to insert, Session 2 loses in a deadlock every time.

So, a delete statement in Session 1 might look something like this: DELETE tblA FROM tblQ LEFT JOIN tblX on ... LEFT JOIN tblA a ON tblQ.Qid = tblA.Qid WHERE ... a.QId IS NULL and ...

The deadlock seems to be caused from contention between querying tblA while Session 2, [3, 4, 5, ..., n] try to insert into tblA.

In my case I could change the isolation level of Session 1's transaction to be SERIALIZABLE. When I did this: The transaction manager has disabled its support for remote/network transactions.

So, I could follow instructions in the accepted answer here to get around it: The transaction manager has disabled its support for remote/network transactions

But a) I wasn't comfortable with changing the isolation level to SERIALIZABLE in the first place- supposedly it degrades performance and may have other consequences I haven't considered, b) didn't understand why doing this suddenly caused the transaction to have a problem working across linked servers, and c) don't know what possible holes I might be opening up by enabling network access.

There seemed to be just 6 queries within a very large transaction that are causing the trouble.

So, I read about TABLOCK and TabLOCKX.

I wasn't crystal clear on the differences, and didn't know if either would work. But it seemed like it would. First I tried TABLOCK and it didn't seem to make any difference. The competing sessions generated the same deadlocks. Then I tried TABLOCKX, and no more deadlocks.

So, in six places, all I needed to do was add a WITH (TABLOCKX).

So, a delete statement in Session 1 might look something like this: DELETE tblA FROM tblQ q LEFT JOIN tblX x on ... LEFT JOIN tblA a WITH (TABLOCKX) ON tblQ.Qid = tblA.Qid WHERE ... a.QId IS NULL and ...

Python 3 handles strings a bit different. Originally there was just one type for strings: str. When unicode gained traction in the '90s the new unicode type was added to handle Unicode without breaking pre-existing code¹. This is effectively the same as str but with multibyte support.

In Python 3 there are two different types:

• The bytes type. This is just a sequence of bytes, Python doesn't know anything about how to interpret this as characters.
• The str type. This is also a sequence of bytes, but Python knows how to interpret those bytes as characters.
• The separate unicode type was dropped. str now supports unicode.

In Python 2 implicitly assuming an encoding could cause a lot of problems; you could end up using the wrong encoding, or the data may not have an encoding at all (e.g. it’s a PNG image).
Explicitly telling Python which encoding to use (or explicitly telling it to guess) is often a lot better and much more in line with the "Python philosophy" of "explicit is better than implicit".

This change is incompatible with Python 2 as many return values have changed, leading to subtle problems like this one; it's probably the main reason why Python 3 adoption has been so slow. Since Python doesn't have static typing² it's impossible to change this automatically with a script (such as the bundled 2to3).

• You can convert str to bytes with bytes('h€llo', 'utf-8'); this should produce b'H\xe2\x82\xacllo'. Note how one character was converted to three bytes.
• You can convert bytes to str with b'H\xe2\x82\xacllo'.decode('utf-8').

Of course, UTF-8 may not be the correct character set in your case, so be sure to use the correct one.

In your specific piece of code, nextline is of type bytes, not str, reading stdout and stdin from subprocess changed in Python 3 from str to bytes. This is because Python can't be sure which encoding this uses. It probably uses the same as sys.stdin.encoding (the encoding of your system), but it can't be sure.

You need to replace:

sys.stdout.write(nextline)

with:

sys.stdout.write(nextline.decode('utf-8'))

or maybe:

sys.stdout.write(nextline.decode(sys.stdout.encoding))

You will also need to modify if nextline == '' to if nextline == b'' since:

>>> '' == b''
False

Also see the Python 3 ChangeLog, PEP 358, and PEP 3112.

¹ There are some neat tricks you can do with ASCII that you can't do with multibyte character sets; the most famous example is the "xor with space to switch case" (e.g. chr(ord('a') ^ ord(' ')) == 'A') and "set 6th bit to make a control character" (e.g. ord('\t') + ord('@') == ord('I')). ASCII was designed in a time when manipulating individual bits was an operation with a non-negligible performance impact.

² Yes, you can use function annotations, but it's a comparatively new feature and little used.

You can also use regions. See https://www.myandroidsolutions.com/2014/06/21/android-studio-intellij-idea-code-regions/

Perhaps slightly more long winded than you want, but i've used more code than maybe nescessary in order for it to be more readable.

That said, it comes out with the same result as you are getting - what is it you want/expect it to come out with?

//Today is whenever I want it to be.
$today = mktime(0,0,0,3,31,2011);

$hour   = date("H",$today);
$minute = date("i",$today);
$second = date("s",$today);
$month  = date("m",$today);
$day    = date("d",$today);
$year   = date("Y",$today);

echo "Today: ".date('Y-m-d', $today)."<br/>";
echo "Recalulated: ".date("Y-m-d",mktime($hour,$minute,$second,$month-1,$day,$year));

If you just want the month and year, then just set the day to be '01' rather than taking 'todays' day:

 $day = 1;

That should give you what you need. You can just set the hour, minute and second to zero as well as you aren't interested in using those.

 date("Y-m",mktime(0,0,0,$month-1,1,$year);

Cuts it down quite a bit ;-)

Just use it as you would a non-concurrent collection. The Concurrent[Collection] classes wrap the regular collections so that you don't have to think about synchronizing access.

Edit: ConcurrentLinkedList isn't actually just a wrapper, but rather a better concurrent implementation. Either way, you don't have to worry about synchronization.

First, you declared $db outside the function. If you want to use it inside the function, you should put this at the begining of your function code:

global $db;

And I guess, when you wrote:

if($result->num_rows){
        return (mysqli_result($query, 0) == 1) ? true : false;

what you really wanted was:

if ($result->num_rows==1) { return true; } else { return false; }

The best way is probably to use:

:%s/phrase//gc

c asks for confirmation before each deletion. g allows multiple replacements to occur on the same line.

You can also just search using /phrase, select the next match with gn, and delete it with d.

according to MSDN

RAISERROR ( { msg_id | msg_str | @local_variable }
    { ,severity ,state }
    [ ,argument [ ,...n ] ] )
    [ WITH option [ ,...n ] ]

16 would be the severity.
1 would be the state.

The error you get is because you have not properly supplied the required parameters for the RAISEERROR function.

Finally, I get the cell using the following code:

UITableViewCell *cell = (UITableViewCell *)[(UITableView *)self.view cellForRowAtIndexPath:nowIndex];

Because the class is extended UITableViewController:

@interface SearchHotelViewController : UITableViewController

So, the self is "SearchHotelViewController".

$("#closeLink").click(closeIt);

Let's say you want to call your function passing some args to it i.e., closeIt(1, false). Then, you should build an anonymous function and call closeIt from it.

$("#closeLink").click(function() {
    closeIt(1, false);
});

You could try something like this:

I have initialzed the array for having value 5, you could put your number similarly.

int[] arr = new int[10]; // your initial array

arr = arr.Select(i => 5).ToArray(); // array initialized to 5.

Using Linq we can simplify this by this

 Enumerable.Range(0, (int)(to - from).TotalHours + 1)
            .Select(i => from.AddHours(i)).Where(date => date.TimeOfDay >= new TimeSpan(8, 0, 0) && date.TimeOfDay <= new TimeSpan(18, 0, 0))

'Load'- inserts a file's contents.(Parse file every time the file is being called)

'Require'- inserts a file parsed content.(File parsed once and stored in memory)

'Include'- includes the module into the class and can use methods inside the module as class's instance method

'Extend'- includes the module into the class and can use methods inside the module as class method

For me its solved follow the following steps :

One reason for this occur is if you don't have a start page or wrong start page set under your web project's properties. So do this:

1- Right click on your MVC project

2- Choose "Properties"

3- Select the "Web" tab

4- Select "Specific Page"

Assuming you have a controller called HomeController and an action method called Index, enter "home/index" in to the text box corresponding to the "Specific Page" radio button.

Now, if you launch your web application, it will take you to the view rendered by the HomeController's Index action method.

Simply give them the same name:

<input type="radio" name="radAnswer" />

You can convert a numpy array to list and get its index .

for example:

tmp = [1,2,3,4,5] #python list
a = numpy.array(tmp) #numpy array
i = list(a).index(2) # i will return index of 2, which is 1

this is just what you wanted.

Besides the way suggested in the "possible duplicate", the other main way of getting around this problem is for the array itself (or at least a template of one) to be supplied by the caller, who will hopefully know the concrete type and can thus safely create the array.

This is the way methods like ArrayList.toArray(T[]) are implemented. I'd suggest you take a look at that method for inspiration. Better yet, you should probably be using that method anyway as others have noted.

Note: This is not unicode compliant. "IU".split('') results in the 4 character array ["I", "?", "?", "u"] which can lead to dangerous bugs. See answers below for safe alternatives.

Just split it by an empty string.

var output = "Hello world!".split('');_x000D_
console.log(output);

See the String.prototype.split() MDN docs.

function isNumber(n) {
  return !isNaN(parseFloat(n)) && isFinite(n);
}

from here

If you are doing a full round-trip post-back, you can just make the button disappear. If there are validation errors, the button will be visible again upon reload of the page.

First set add a style to your button:

<h:commandButton id="SaveBtn" value="Save"
    styleClass="hideOnClick"
    actionListener="#{someBean.saveAction()}"/>

Then make it hide when clicked.

$(document).ready(function() {
    $(".hideOnClick").click(function(e) {
        $(e.toElement).hide();
    });
});

I'd add Commons NullComparator instead to avoid some problems...

EDIT: There are better/more coherent answers to this question in other questions:

• Sibling package imports
• Relative imports for the billionth time

Why doesn't it work? It's because python doesn't record where a package was loaded from. So when you do python -m test_A.test, it basically just discards the knowledge that test_A.test is actually stored in package (i.e. package is not considered a package). Attempting from ..A import foo is trying to access information it doesn't have any more (i.e. sibling directories of a loaded location). It's conceptually similar to allowing from ..os import path in a file in math. This would be bad because you want the packages to be distinct. If they need to use something from another package, then they should refer to them globally with from os import path and let python work out where that is with $PATH and $PYTHONPATH.

When you use python -m package.test_A.test, then using from ..A import foo resolves just fine because it kept track of what's in package and you're just accessing a child directory of a loaded location.

Why doesn't python consider the current working directory to be a package? NO CLUE, but gosh it would be useful.

You can use JsonConvert from Newtonsoft library. To serialize an object and write to a file in json format:

File.WriteAllText(filePath, JsonConvert.SerializeObject(obj));

And to deserialize it back into object:

var obj = JsonConvert.DeserializeObject<ObjType>(File.ReadAllText(filePath));

This article helped me. I was submitting form via AJAX and forgotten to use return false (after my ajax request) which led to classic form submission but strangely it was not completed.

First; the way that the code in the article does it is evil. throw ex will reset the call stack in the exception to the point where this throw statement is; losing the information about where the exception actually was created.

Second, if you just catch and re-throw like that, I see no added value, the code example above would be just as good (or, given the throw ex bit, even better) without the try-catch.

However, there are cases where you might want to catch and rethrow an exception. Logging could be one of them:

try 
{
    // code that may throw exceptions    
}
catch(Exception ex) 
{
    // add error logging here
    throw;
}

There are many ways to address your problem.

1. First one as accepted answer by @robert. Here is the generalised solution for it:

def multi_dimensional_list(value, *args):
  #args dimensions as many you like. EG: [*args = 4,3,2 => x=4, y=3, z=2]
  #value can only be of immutable type. So, don't pass a list here. Acceptable value = 0, -1, 'X', etc.
  if len(args) > 1:
    return [ multi_dimensional_list(value, *args[1:]) for col in range(args[0])]
  elif len(args) == 1: #base case of recursion
    return [ value for col in range(args[0])]
  else: #edge case when no values of dimensions is specified.
    return None

Eg:

>>> multi_dimensional_list(-1, 3, 4)  #2D list
[[-1, -1, -1, -1], [-1, -1, -1, -1], [-1, -1, -1, -1]]
>>> multi_dimensional_list(-1, 4, 3, 2)  #3D list
[[[-1, -1], [-1, -1], [-1, -1]], [[-1, -1], [-1, -1], [-1, -1]], [[-1, -1], [-1, -1], [-1, -1]], [[-1, -1], [-1, -1], [-1, -1]]]
>>> multi_dimensional_list(-1, 2, 3, 2, 2 )  #4D list
[[[[-1, -1], [-1, -1]], [[-1, -1], [-1, -1]], [[-1, -1], [-1, -1]]], [[[-1, -1], [-1, -1]], [[-1, -1], [-1, -1]], [[-1, -1], [-1, -1]]]]

P.S If you are keen to do validation for correct values for args i.e. only natural numbers, then you can write a wrapper function before calling this function.

2. Secondly, any multidimensional dimensional array can be written as single dimension array. This means you don't need a multidimensional array. Here are the function for indexes conversion:

def convert_single_to_multi(value, max_dim):
  dim_count = len(max_dim)
  values = [0]*dim_count
  for i in range(dim_count-1, -1, -1): #reverse iteration
    values[i] = value%max_dim[i]
    value /= max_dim[i]
  return values


def convert_multi_to_single(values, max_dim):
  dim_count = len(max_dim)
  value = 0
  length_of_dimension = 1
  for i in range(dim_count-1, -1, -1): #reverse iteration
    value += values[i]*length_of_dimension
    length_of_dimension *= max_dim[i]
  return value

Since, these functions are inverse of each other, here is the output:

>>> convert_single_to_multi(convert_multi_to_single([1,4,6,7],[23,45,32,14]),[23,45,32,14])
[1, 4, 6, 7]
>>> convert_multi_to_single(convert_single_to_multi(21343,[23,45,32,14]),[23,45,32,14])
21343

3. If you are concerned about performance issues then you can use some libraries like pandas, numpy, etc.

Clustering uses shared storage of some kind (a drive cage or a SAN, for example), and puts two database front-ends on it. The front end servers share an IP address and cluster network name that clients use to connect, and they decide between themselves who is currently in charge of serving client requests.

If you're asking about a particular database server, add that to your question and we can add details on their implementation, but at its core, that's what clustering is.

See here for starting the service and here for how to make it permanent. In short to test it, open a "DOS" terminal with administrator privileges and write:

shell> "C:\Program Files\MySQL\[YOUR MYSQL VERSION PATH]\bin\mysqld"

I was having a similar problem with loading web fonts, when I clicked on 'add CORS configuration', in the bucket properties, this code was already there:

<?xml version="1.0" encoding="UTF-8"?>
<CORSConfiguration xmlns="http://s3.amazonaws.com/doc/2006-03-01/">
    <CORSRule>
        <AllowedOrigin>*</AllowedOrigin>
        <AllowedMethod>GET</AllowedMethod>
        <AllowedMethod>HEAD</AllowedMethod>
        <MaxAgeSeconds>3000</MaxAgeSeconds>
        <AllowedHeader>Authorization</AllowedHeader>
    </CORSRule>
</CORSConfiguration> 

I just clicked save and it worked a treat, my custom web fonts were loading in IE & Firefox. I'm no expert on this, I just thought this might help you out.

Well, it has 32 bits and hence can store 2^32 different values. Half of those are negative.

The solution is 2,147,483,647

And the lowest is -2,147,483,648.

(Notice that there is one more negative value.)

Here is the method which is used in Commerce SagePay and in Commerce Paypoint Drupal modules which basically compares document.location.href with the old value by first loading its own iframe, then external one.

So basically the idea is to load the blank page as a placeholder with its own JS code and hidden form. Then parent JS code will submit that hidden form where its #action points to the external iframe. Once the redirect/submit happens, the JS code which still running on that page can track your document.location.href value changes.

Here is example JS used in iframe:

;(function($) {
  Drupal.behaviors.commercePayPointIFrame = {
    attach: function (context, settings) {
      if (top.location != location) {
        $('html').hide();
        top.location.href = document.location.href;
      }
    }
  }
})(jQuery);

And here is JS used in parent page:

;(function($) {
  /**
   * Automatically submit the hidden form that points to the iframe.
   */
  Drupal.behaviors.commercePayPoint = {
    attach: function (context, settings) {
      $('div.payment-redirect-form form', context).submit();
      $('div.payment-redirect-form #edit-submit', context).hide();
      $('div.payment-redirect-form .checkout-help', context).hide();
    }
  }
})(jQuery);

Then in temporary blank landing page you need to include the form which will redirect to the external page.

To be able to disable/enable selects first of all your selects need an ID or class. Then you could do something like this:

Disable:

$('#id').attr('disabled', 'disabled');

Enable:

$('#id').removeAttr('disabled');

Unlike standard arithmetic, which desires matching dimensions, dot products require that the dimensions are one of:

• (X..., A, B) dot (Y..., B, C) -> (X..., Y..., A, C), where ... means "0 or more different values
• (B,) dot (B, C) -> (C,)
• (A, B) dot (B,) -> (A,)
• (B,) dot (B,) -> ()

Your problem is that you are using np.matrix, which is totally unnecessary in your code - the main purpose of np.matrix is to translate a * b into np.dot(a, b). As a general rule, np.matrix is probably not a good choice.

I don't suggest you just hidding the stricts errors on your project. Intead, you should turn your method to static or try to creat a new instance of the object:

$var = new YourClass();
$var->method();

You can also use the new way to do the same since PHP 5.4:

(new YourClass)->method();

I hope it helps you!

As @cs95 mentioned in a comment, to drop only one level, use:

df.reset_index(level=[...])

This avoids having to redefine your desired index after reset.

After few hours of searching, I just solved this issue with a few lines of code

Your model

      [Required(ErrorMessage = "Enter the issued date.")]
      [DataType(DataType.Date)]
      public DateTime IssueDate { get; set; }

Razor Page

     @Html.TextBoxFor(model => model.IssueDate)
     @Html.ValidationMessageFor(model => model.IssueDate)

Jquery DatePicker

<script type="text/javascript">
    $(document).ready(function () {
        $('#IssueDate').datepicker({
            dateFormat: "dd/mm/yy",
            showStatus: true,
            showWeeks: true,
            currentText: 'Now',
            autoSize: true,
            gotoCurrent: true,
            showAnim: 'blind',
            highlightWeek: true
        });
    });
</script>

Webconfig File

    <system.web>
        <globalization uiCulture="en" culture="en-GB"/>
    </system.web>

Now your text-box will accept "dd/MM/yyyy" format.

You can use   for spaces, < for < (less than, entity number <) and > for > (greater than, entity number >).

A complete list can be found at HTML Entities.

Dependencies are singletons within the scope of an injector. In below example, a single HeroService instance is shared among the HeroesComponent and its HeroListComponent children.

Step 1. Create singleton class with @Injectable decorator

@Injectable()
export class HeroService {
  getHeroes() { return HEROES;  }
}

Step 2. Inject in constructor

export class HeroListComponent { 
  constructor(heroService: HeroService) {
    this.heroes = heroService.getHeroes();
  }

Step 3. Register provider

@NgModule({
  imports: [
    BrowserModule,
    FormsModule,
    routing,
    HttpModule,
    JsonpModule
  ],
  declarations: [
    AppComponent,
    HeroesComponent,
    routedComponents
  ],
  providers: [
    HeroService
  ],
  bootstrap: [
    AppComponent
  ]
})
export class AppModule { }

In a bash-like environment you can use:

keytool -list -v -keystore cacerts.jks | grep 'Alias name:' | grep -i foo

This command consist of 3 parts. As stated above, the 1st part will list all trusted certificates with all the details and that's why the 2nd part comes to filter only the alias information among those details. And finally in the 3rd part you can search for a specific alias (or part of it). The -i turns the case insensitive mode on. Thus the given command will yield all aliases containing the pattern 'foo', f.e. foo, 123_FOO, fooBar, etc. For more information man grep.

If you want multiple messages from a queue, say 10 messages, the command to use is:

rabbitmqadmin get queue=<QueueName> ackmode=ack_requeue_true count=10

If you don't want the messages requeued, just change ackmode to ack_requeue_false.

@tcaswell already answered, but I was in the middle of typing my answer up, so I'll go ahead and post it...

There are a number of different ways you could do this. To begin with, matplotlib will automatically cycle through colors. By default, it cycles through blue, green, red, cyan, magenta, yellow, black:

import matplotlib.pyplot as plt
import numpy as np

x = np.linspace(0, 1, 10)
for i in range(1, 6):
    plt.plot(x, i * x + i, label='$y = {i}x + {i}$'.format(i=i))
plt.legend(loc='best')
plt.show()

If you want to control which colors matplotlib cycles through, use ax.set_color_cycle:

import matplotlib.pyplot as plt
import numpy as np

x = np.linspace(0, 1, 10)
fig, ax = plt.subplots()
ax.set_color_cycle(['red', 'black', 'yellow'])
for i in range(1, 6):
    plt.plot(x, i * x + i, label='$y = {i}x + {i}$'.format(i=i))
plt.legend(loc='best')
plt.show()

If you'd like to explicitly specify the colors that will be used, just pass it to the color kwarg (html colors names are accepted, as are rgb tuples and hex strings):

import matplotlib.pyplot as plt
import numpy as np

x = np.linspace(0, 1, 10)
for i, color in enumerate(['red', 'black', 'blue', 'brown', 'green'], start=1):
    plt.plot(x, i * x + i, color=color, label='$y = {i}x + {i}$'.format(i=i))
plt.legend(loc='best')
plt.show()

Finally, if you'd like to automatically select a specified number of colors from an existing colormap:

import matplotlib.pyplot as plt
import numpy as np

x = np.linspace(0, 1, 10)
number = 5
cmap = plt.get_cmap('gnuplot')
colors = [cmap(i) for i in np.linspace(0, 1, number)]

for i, color in enumerate(colors, start=1):
    plt.plot(x, i * x + i, color=color, label='$y = {i}x + {i}$'.format(i=i))
plt.legend(loc='best')
plt.show()

UNION puts lines from queries after each other, while JOIN makes a cartesian product and subsets it -- completely different operations. Trivial example of UNION:

mysql> SELECT 23 AS bah
    -> UNION
    -> SELECT 45 AS bah;
+-----+
| bah |
+-----+
|  23 | 
|  45 | 
+-----+
2 rows in set (0.00 sec)

similary trivial example of JOIN:

mysql> SELECT * FROM 
    -> (SELECT 23 AS bah) AS foo 
    -> JOIN 
    -> (SELECT 45 AS bah) AS bar
    -> ON (33=33);
+-----+-----+
| foo | bar |
+-----+-----+
|  23 |  45 | 
+-----+-----+
1 row in set (0.01 sec)

Take a look at my implementation. It's safe from null lists.

 IList<string> all= new List<string>();

 if (letterForm.SecretaryPhone!=null)// first list may be null
     all=all.Concat(letterForm.SecretaryPhone).ToList();

 if (letterForm.EmployeePhone != null)// second list may be null
     all= all.Concat(letterForm.EmployeePhone).ToList(); 

 if (letterForm.DepartmentManagerName != null) // this is not list (its just string variable) so wrap it inside list then concat it 
     all = all.Concat(new []{letterForm.DepartmentManagerPhone}).ToList();

Thanks for your replies. Here's what I did:

git gc
git gc --aggressive
git prune

That seemed to have done the trick. I started with around 10.5MB and now it's little more than 980KBs.

Update

This answer is outdated. You can do this a lot more simply, as pointed out in another answer below:

ul {
  list-style-position: outside;
}

See https://www.w3schools.com/cssref/pr_list-style-position.asp

Original Answer

I'm surprised to see this hasn't been solved yet. You can make use of the browser's table layout algorithm (without using tables) like this:

ol {
    counter-reset: foo;
    display: table;
}

ol > li {
    counter-increment: foo;
    display: table-row;
}

ol > li::before {
    content: counter(foo) ".";
    display: table-cell; /* aha! */
    text-align: right;
}

Demo: http://jsfiddle.net/4rnNK/1/

To make it work in IE8, use the legacy :before notation with one colon.

You can try using FormulaLocal property instead of Formula. Then the semicolon should work.

I would suggest following extension methods for string parsing into int value with ability to define default value in case parsing is not possible:

public static int ParseInt(this string value, int defaultIntValue = 0)
        {
            return int.TryParse(value, out var parsedInt) ? parsedInt : defaultIntValue;
        }

public static int? ParseNullableInt(this string value)
        {
            if (string.IsNullOrEmpty(value))
                return null;

            return value.ParseInt();
        }

Ok, I am not sure what are you using(MySQL, SLQ Server, Oracle, MS Access..) But you can try the code below. It work in W3School example DB. Here try this:

SELECT city, max(length(city)) FROM Customers;

Here is the approach I used to produce code that was compatible with both python2 and python3 and always produced utf8 output. I found this answer elsewhere, but I can't remember the source.

This approach works by replacing sys.stdout with something that isn't quite file-like (but still only using things in the standard library). This may well cause problems for your underlying libraries, but in the simple case where you have good control over how sys.stdout out is used through your framework this can be a reasonable approach.

sys.stdout = io.open(sys.stdout.fileno(), 'w', encoding='utf8')

That's my workaround.

@property
def language(self):
    return self._language
@language.setter
def language(self, value):
    # WORKAROUND to get a "getter-only" behavior
    # set the value only if the attribute does not exist
    try:
        if self.language == value:
            pass
        print("WARNING: Cannot set attribute \'language\'.")
    except AttributeError:
        self._language = value

In pandas 0.20.2 you can do:

from pandas.api.types import is_string_dtype
from pandas.api.types import is_numeric_dtype

is_string_dtype(df['A'])
>>>> True

is_numeric_dtype(df['B'])
>>>> True

So your code becomes:

for y in agg.columns:
    if (is_string_dtype(agg[y])):
        treat_str(agg[y])
    elif (is_numeric_dtype(agg[y])):
        treat_numeric(agg[y])

I was facing with this problem some time ago and I found java.util.LinkedList is best for my case. It has several methods, with different namings, but they're doing what is needed:

push()    -> LinkedList.addLast(); // Or just LinkedList.add();
pop()     -> LinkedList.pollLast();
shift()   -> LinkedList.pollFirst();
unshift() -> LinkedList.addFirst();

I know this is very Old post. Since we don't have any thing sun.misc in maven we can easily use

StringUtils.newStringUtf8(Base64.encodeBase64(encVal)); From org.apache.commons.codec.binary.Base64

Even if you use exceptions, it still output errors.
You have to set $MailerDebug to False wich should look like this

$mail = new PHPMailer();
$mail->MailerDebug = false;

You could use find to solve your problem

https://lodash.com/docs/#find

const data = [{"a": 1}, {"b": 2}]
const item = {"b": 2}


find(data, item)
// > true

Assuming you can put ID's on the inputs:

$('#name').change(function() {
    $('#firstname').val($(this).val());
});

JSFiddle Example

Otherwise you'll have to select using the names:

$('input[name="name"]').change(function() {
    $('input[name="firstname"]').val($(this).val());
});

I would love the ability to use a role as a collection of tasks such that, in my playbook, I can choose which subset of tasks to run. Unfortunately, the playbook can only load them all in and then you have to use the --tags option on the cmdline to choose which tasks to run. The problem with this is that all of the tasks will run unless you remember to set --tags or --skip-tags.

I have set up some tasks, however, with a when: clause that will only fire if a var is set.

e.g.

# role/stuff/tasks/main.yml
- name: do stuff
  when: stuff|default(false)

Now, this task will not fire by default, but only if I set the stuff=true

$ ansible-playbook -e '{"stuff":true}'

or in a playbook:

roles:
- {"role":"stuff", "stuff":true}

time1 is the key of the most outer dictionary, eg, feb2012. So then you're trying to index the string, but you can only do this with integers. I think what you wanted was:

for info in courses[time1][course]:

As you're going through each dictionary, you must add another nest.

Well, it's just a javascript object, so you can manipulate data.items just like you would an ordinary array. If you do:

data.items.pop();

your items array will be 1 item shorter.

Another way to do it would be to inspect the url bar in chrome to find the id of the element, have your WebDriver click that element, and then send the keys you use to copy and paste using the keys common function from selenium, and then printing it out or storing it as a variable, etc.

Here's a practical example (build a dataset from your current location):

$ds = new-object System.Data.DataSet
$ds.Tables.Add("tblTest")
[void]$ds.Tables["tblTest"].Columns.Add("Name",[string])
[void]$ds.Tables["tblTest"].Columns.Add("Path",[string])

dir | foreach {
    $dr = $ds.Tables["tblTest"].NewRow()
    $dr["Name"] = $_.name
    $dr["Path"] = $_.fullname
    $ds.Tables["tblTest"].Rows.Add($dr)
}


$ds.Tables["tblTest"]

$ds.Tables["tblTest"] is an object that you can manipulate just like any other Powershell object:

$ds.Tables["tblTest"] | foreach {
    write-host 'Name value is : $_.name
    write-host 'Path value is : $_.path
}

I second the recommendations for using an ORM like Hibernate. However, there are certainly situations where that doesn't work, so I'll take this opportunity to tout some stuff that i've helped to write: SqlBuilder is a java library for dynamically building sql statements using the "builder" style. it's fairly powerful and fairly flexible.

If your chart uses both fill and color aesthetics, you can remove the legend with:

+ guides(fill=FALSE, color=FALSE)

This isn't really possible in HTML unless you use absolute positioning or javascript. So one solution would be to give this CSS to #bottom_link:

#bottom_link {
    position:absolute;
    bottom:0;
}

Otherwise you'd have to use some javascript. Here's a jQuery block that should do the trick, depending on the simplicity of the page.

$('#bottom_link').css({
    position: 'relative',
    top: $(this).parent().height() - $(this).height()
});

Every time setColor gets hit, you are setting count = 1. You would need to define count outside of the scope of the function. Example:

var count=1;
function setColor(btn, color){
    var property = document.getElementById(btn);
    if (count == 0){
        property.style.backgroundColor = "#FFFFFF"
        count=1;        
    }
    else{
        property.style.backgroundColor = "#7FFF00"
        count=0;
    }

}

In my case I used sudo mkdir projectFolder to create folder. It was owned by root user and I was logged in using non root user.

So I changed the folder permission using command sudo chown mynonrootuser:mynonrootuser projectFolder and then it worked fine.

In my case i turn Windows Firewall off

1- Open Windows Firewall by clicking the Start button Picture of the Start button, and then clicking Control Panel. In the search box, type firewall, and then click Windows Firewall.

2- Click Turn Windows Firewall on or off. Administrator permission required If you're prompted for an administrator password or confirmation, type the password or provide confirmation.

3- Click Turn off Windows Firewall (not recommended) under each network location that you want to stop trying to protect, and then click OK. Was this page helpful?

Some times you need also

1. To stop all Vpn client services (fortiClient ,vpn Client ...)
2. To stop Antivirus Firewall ( exemple Kaspersky => Configuration => Anti-Hacker)

I've been working on something similar and after a few tries and fails came up with this:

Example: STRING-TO-TEST-ON = 'ab,cd,ef,gh'

I wanted to extract everything after the last occurrence of "," (comma) from the string... resulting in "gh".

My query is:

SELECT SUBSTR('ab,cd,ef,gh' FROM (LENGTH('ab,cd,ef,gh') - (LOCATE(",",REVERSE('ab,cd,ef,gh'))-1)+1)) AS `wantedString`

Now let me try and explain what I did ...

1. I had to find the position of the last "," from the string and to calculate the wantedString length, using LOCATE(",",REVERSE('ab,cd,ef,gh'))-1 by reversing the initial string I actually had to find the first occurrence of the "," in the string ... which wasn't hard to do ... and then -1 to actually find the string length without the ",".

2. calculate the position of my wantedString by subtracting the string length I've calculated at 1st step from the initial string length:

   LENGTH('ab,cd,ef,gh') - (LOCATE(",",REVERSE('ab,cd,ef,gh'))-1)+1

I have (+1) because I actually need the string position after the last "," .. and not containing the ",". Hope it makes sense.

3. all it remain to do is running a SUBSTR on my initial string FROM the calculated position.

I haven't tested the query on large strings so I do not know how slow it is. So if someone actually tests it on a large string I would very happy to know the results.

Similar situation for following configuration:

• Windows Server 2012 R2 Standard
• MS SQL server 2008 (tested also SQL 2012)
• Oracle 10g client (OracleDB v8.1.7)
• MSDAORA provider
• Error ID: 7302

My solution:

• Install 32bit MS SQL Server (64bit MSDAORA doesn't exist)
• Install 32bit Oracle 10g 10.2.0.5 patch (set W7 compatibility on setup.exe)
• Restart SQL services
• Check Allow in process in MSDAORA provider
• Test linked oracle server connection

To get the C# version from code, use this code from the Microsoft documentation to get the .NET Framework version and then match it up using the table that everyone else mentions. You can code up the Framework to C# version map in a dictionary or something to actually have your function return the C# version. Works if you have .NET Framework >= 4.5.

using System;
using Microsoft.Win32;

public class GetDotNetVersion
{
   public static void Main()
   {
      Get45PlusFromRegistry();
   }

   private static void Get45PlusFromRegistry()
   {
      const string subkey = @"SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full\";

      using (var ndpKey = RegistryKey.OpenBaseKey(RegistryHive.LocalMachine, RegistryView.Registry32).OpenSubKey(subkey))
      {
        if (ndpKey != null && ndpKey.GetValue("Release") != null) {
            Console.WriteLine($".NET Framework Version: {CheckFor45PlusVersion((int) ndpKey.GetValue("Release"))}");
        }
         else {
            Console.WriteLine(".NET Framework Version 4.5 or later is not detected.");
         } 
      }

      // Checking the version using >= enables forward compatibility.
      string CheckFor45PlusVersion(int releaseKey)
      {
         if (releaseKey >= 528040)
            return "4.8 or later";
         if (releaseKey >= 461808)
            return "4.7.2";
         if (releaseKey >= 461308)
            return "4.7.1";
         if (releaseKey >= 460798)
            return "4.7";
         if (releaseKey >= 394802)
            return "4.6.2";
         if (releaseKey >= 394254)
            return "4.6.1";      
         if (releaseKey >= 393295)
            return "4.6";      
         if (releaseKey >= 379893)
            return "4.5.2";      
         if (releaseKey >= 378675)
            return "4.5.1";      
         if (releaseKey >= 378389)
            return "4.5";      
         // This code should never execute. A non-null release key should mean
         // that 4.5 or later is installed.
         return "No 4.5 or later version detected";
      }
   }
}   
// This example displays output like the following:
//       .NET Framework Version: 4.6.1

Ive come across this many times in my work, an easy work around that I found is to ask if the array element is a Hash by class.

if i.class == Hash

    notation like i[:label] will work in this block and not throw that error

end

No you can't use case and in like this. But you can do

SELECT * FROM Product P    
WHERE @Status='published' and P.Status IN (1,3)
or @Status='standby' and P.Status IN  (2,5,9,6)
or @Status='deleted' and P.Status IN (4,5,8,10)
or P.Status IN (1,3)

BTW you can reduce that to

SELECT * FROM Product P    
WHERE @Status='standby' and P.Status IN (2,5,9,6)
or @Status='deleted' and P.Status IN (4,5,8,10)
or P.Status IN (1,3)

since or P.Status IN (1,3) gives you also all records of @Status='published' and P.Status IN (1,3)

You can do this:

isHidden = function(element){
    return (element.style.display === "none");
};

if(isHidden($("element")) == true){
    // Something
}

The solution is fairly straight forward. To ensure that we don't impact the width of the cells in the table, we'll turn off white-space. To ensure we get a horizontal scroll bar, we'll turn on overflow-x. And that's pretty much it:

.container {
    width: 30em;
    overflow-x: auto;
    white-space: nowrap;
}

You can see the end-result here, or in the animation below. If the table determines the height of your container, you should not need to explicitly set overflow-y to hidden. But understand that is also an option.

A few others that have not been mentioned:

For mini pies, lines and bars, Peity is brilliant, simple, tiny, fast, uses really elegant markup.

I'm not sure of it's relationship with Flot (given its name), but Flotr2 is pretty good, certainly does better pies than Flot.

Bluff produces nice-looking line graphs, but I had a bit of trouble with its pies.

Not what I was after, but another commercial product (much like Highcharts) is TeeChart.

There are some great answers already posted, but I would like to contribute in a different way. If you want to visualize what all is happening you can assume that a compiler can perform close to 10^8 operations in ~1sec. If the input is given in 10^8, you might want to design an algorithm that operates in a linear fashion(like an un-nested for-loop). below is the table that can help you to quickly figure out the type of algorithm you want to figure out ;)

You can install the package gcolor2 for this:

sudo apt-get install gcolor2

Then:

Applications -> Graphics -> GColor2

for n in range(6,0,-1):
    print n
# prints [6, 5, 4, 3, 2, 1]

try

$("#mylist").children().length

In my case addInterceptor()didn't work to add HTTP headers to my request, I had to use addNetworkInterceptor(). Code is as follows:

OkHttpClient.Builder httpClient = new OkHttpClient.Builder();
httpClient.addNetworkInterceptor(new AddHeaderInterceptor());

And the interceptor code:

public class AddHeaderInterceptor implements Interceptor {
    @Override
    public Response intercept(Chain chain) throws IOException {

        Request.Builder builder = chain.request().newBuilder();
        builder.addHeader("Authorization", "MyauthHeaderContent");

        return chain.proceed(builder.build());
    }
}

This and more examples on this gist

Only first part of Justin's answer is correct. Using "%.3g" will not work for all cases as .3 is not the precision, but total number of digits. Try it for numbers like 1000.123 and it breaks.

So, I would use what Justin is suggesting:

>>> ('%.4f' % 12340.123456).rstrip('0').rstrip('.')
'12340.1235'
>>> ('%.4f' % -400).rstrip('0').rstrip('.')
'-400'
>>> ('%.4f' % 0).rstrip('0').rstrip('.')
'0'
>>> ('%.4f' % .1).rstrip('0').rstrip('.')
'0.1'

Since I have to reuse this few time, I came up with this class that simply help to abstract how the query string is composed.

public class UriBuilderExt
{
    private NameValueCollection collection;
    private UriBuilder builder;

    public UriBuilderExt(string uri)
    {
        builder = new UriBuilder(uri);
        collection = System.Web.HttpUtility.ParseQueryString(string.Empty);
    }

    public void AddParameter(string key, string value) {
        collection.Add(key, value);
    }

    public Uri Uri{
        get
        {
            builder.Query = collection.ToString();
            return builder.Uri;
        }
    }

}

The use will be simplify to something like this:

var builder = new UriBuilderExt("http://example.com/");
builder.AddParameter("foo", "bar<>&-baz");
builder.AddParameter("bar", "second");
var uri = builder.Uri;

that will return the uri: http://example.com/?foo=bar%3c%3e%26-baz&bar=second

Got it :D

function getContextPath() {
   return window.location.pathname.substring(0, window.location.pathname.indexOf("/",2));
}
alert(getContextPath());

Important note: Does only work for the "root" context path. Does not work with "subfolders", or if context path has a slash ("/") in it.

I'll slightly expand @assylias answer to take time zone into account. There are at least two ways to get LocalDateTime for specific time zone.

You can use setDefault time zone for whole application. It should be called before any timestamp -> java.time conversion:

public static void main(String... args) {
    TimeZone utcTimeZone = TimeZone.getTimeZone("UTC");
    TimeZone.setDefault(utcTimeZone);
    ...
    timestamp.toLocalDateTime().toLocalDate();
}

Or you can use toInstant.atZone chain:

timestamp.toInstant()
        .atZone(ZoneId.of("UTC"))
        .toLocalDate();

Your web_window variable must have gone out of scope when you tried to close the window. Add this line into your _openpageview function to test:

setTimeout(function(){web_window.close();},1000);

Calling a JavaScript function from code behind

Step 1 Add your Javascript code

<script type="text/javascript" language="javascript">
    function Func() {
        alert("hello!")
    }
</script>

Step 2 Add 1 Script Manager in your webForm and Add 1 button too

Step 3 Add this code in your button click event

ScriptManager.RegisterStartupScript(this.Page, Page.GetType(), "text", "Func()", true);

a <div> is a logical division in your content, semantically this would be my first choice if I wanted to group the heading with the list:

<div class="mydiv">
    <h3>The heading</h3>
    <ul>
       <li>item</li>
       <li>item</li>
       <li>item</li>
    </ul>
</div>

then you can use the following css to style everything together as one unit

.mydiv{}
.mydiv h3{}
.mydiv ul{}
.mydiv ul li{}
etc...

Or write to the response stream:

Response.Write("<script>");
Response.Write("window.open('page.html','_blank')");
Response.Write("</script>");

Procedure never returns a value.You have to use a output parameter in store procedure.

ALTER PROC TESTLOGIN
@UserName   varchar(50),
@password   varchar(50)
@retvalue int output
 as
 Begin
    declare @return     int 
    set @return  = (Select COUNT(*) 
    FROM    CPUser  
    WHERE   UserName = @UserName AND Password = @password)

   set @retvalue=@return
  End

Then you have to add a sqlparameter from c# whose parameter direction is out. Hope this make sense.

I had the same problem recently and this helped me:

    header('Content-Description: File Transfer'); 
    header('Content-Type: application/octet-stream'); 
    header('Content-Disposition: attachment; filename="FILENAME"');

When you scheduled task, just select "Run whether user is logged on or not" under the "General" tab.

Alternate way is to let the task run as another user.

Like @Sunkas wrote, performSelector:withObject:afterDelay: is the pendant to the dispatch_after just that it is shorter and you have the normal objective-c syntax. If you need to pass arguments to the block you want to delay, you can just pass them through the parameter withObject and you will receive it in the selector you call:

[self performSelector:@selector(testStringMethod:) 
           withObject:@"Test Test" 
           afterDelay:0.5];

- (void)testStringMethod:(NSString *)string{
    NSLog(@"string  >>> %@", string);
}

If you still want to choose yourself if you execute it on the main thread or on the current thread, there are specific methods which allow you to specify this. Apples Documentation tells this:

If you want the message to be dequeued when the run loop is in a mode other than the default mode, use the performSelector:withObject:afterDelay:inModes: method instead. If you are not sure whether the current thread is the main thread, you can use the performSelectorOnMainThread:withObject:waitUntilDone: or performSelectorOnMainThread:withObject:waitUntilDone:modes: method to guarantee that your selector executes on the main thread. To cancel a queued message, use the cancelPreviousPerformRequestsWithTarget: or cancelPreviousPerformRequestsWithTarget:selector:object: method.

If array is static allocated:

size_t size = sizeof(arr) / sizeof(int);

if array is dynamic allocated(heap):

int *arr = malloc(sizeof(int) * size);

where variable size is a dimension of the arr.

    plt.plot(range(7), [3, 1, 4, 1, 5, 9, 2], 'r-o')
    plt.title('Page One')

I don't think you understand how \n works. The resulting string still just contains a byte with value 10. This is represented in javascript source code with \n.

The code snippet you posted doesn't actually work, but if it did, the newline would be equivalent to \n, unless it's a windows-style newline, in which case it would be \r\n. (but even that the replace would still work).

There are two ways of on how to achieve that according to Apple Developer Documentation

1. NSLayoutConstraint.deactivateConstraints

This is a convenience method that provides an easy way to deactivate a set of constraints with one call. The effect of this method is the same as setting the isActive property of each constraint to false. Typically, using this method is more efficient than deactivating each constraint individually.

// Declaration
class func deactivate(_ constraints: [NSLayoutConstraint])

// Usage
NSLayoutConstraint.deactivate(yourView.constraints)

2. UIView.removeConstraints (Deprecated for >= iOS 8.0)

When developing for iOS 8.0 or later, use the NSLayoutConstraint class’s deactivateConstraints: method instead of calling the removeConstraints: method directly. The deactivateConstraints: method automatically removes the constraints from the correct views.

// Declaration
func removeConstraints(_ constraints: [NSLayoutConstraint])`

// Usage
yourView.removeConstraints(yourView.constraints)

Tips

Using Storyboards or XIBs can be such a pain at configuring the constraints as mentioned on your scenario, you have to create IBOutlets for each ones you want to remove. Even so, most of the time Interface Builder creates more trouble than it solves.

Therefore when having very dynamic content and different states of the view, I would suggest:

1. Creating your views programmatically
2. Layout them and using NSLayoutAnchor
3. Append each constraint that might get removed later to an array
4. Clear them every time before applying the new state

Simple Code

private var customConstraints = [NSLayoutConstraint]()

private func activate(constraints: [NSLayoutConstraint]) {
    customConstraints.append(contentsOf: constraints)
    customConstraints.forEach { $0.isActive = true }
}

private func clearConstraints() {
    customConstraints.forEach { $0.isActive = false }
    customConstraints.removeAll()
}

private func updateViewState() {
    clearConstraints()

    let constraints = [
        view.leadingAnchor.constraint(equalTo: parentView.leadingAnchor),
        view.trailingAnchor.constraint(equalTo: parentView.trailingAnchor),
        view.topAnchor.constraint(equalTo: parentView.topAnchor),
        view.bottomAnchor.constraint(equalTo: parentView.bottomAnchor)
    ]

    activate(constraints: constraints)

    view.layoutIfNeeded()
}

Joking aside, if you're only expecting your input integer to be a zero or a one, you should really be checking that this is the case.

int yourInteger = whatever;
bool yourBool;
switch (yourInteger)
{
    case 0: yourBool = false; break;
    case 1: yourBool = true;  break;
    default:
        throw new InvalidOperationException("Integer value is not valid");
}

The out-of-the-box Convert won't check this; nor will yourInteger (==|!=) (0|1).

The control searches for a view in the following order:

• First in shared folder
• Then in the folder matching the current controller (in your case it's Views/DEF)

As you do not have xxx.cshtml in those locations, it returns a "view not found" error.

Solution: You can use the complete path of your view:

Like

 PartialView("~/views/ABC/XXX.cshtml", zyxmodel);

For single-byte strings (e.g. US-ASCII, ISO 8859 family, etc.) use substr and for multi-byte strings (e.g. UTF-8, UTF-16, etc.) use mb_substr:

// singlebyte strings
$result = substr($myStr, 0, 5);
// multibyte strings
$result = mb_substr($myStr, 0, 5);

With Entity Framework 6.1, you can now do this:

[Index("IX_FirstAndSecond", 1, IsUnique = true)]
public int FirstColumn { get; set; }

[Index("IX_FirstAndSecond", 2, IsUnique = true)]
public int SecondColumn { get; set; }

The second parameter in the attribute is where you can specify the order of the columns in the index.

In the CMakeLists.txt file, create a cache variable, as documented here:

SET(FAB "po" CACHE STRING "Some user-specified option")

Source: http://cmake.org/cmake/help/v2.8.8/cmake.html#command:set

Then, either use the GUI (ccmake or cmake-gui) to set the cache variable, or specify the value of the variable on the cmake command line:

cmake -DFAB:STRING=po

Source: http://cmake.org/cmake/help/v2.8.8/cmake.html#opt:-Dvar:typevalue

Modify your cache variable to a boolean if, in fact, your option is boolean.

"Resource temporarily unavailable" is the error message corresponding to EAGAIN, which means that the operation would have blocked but nonblocking operation was requested. For send(), that could be due to any of:

• explicitly marking the file descriptor as nonblocking with fcntl(); or
• passing the MSG_DONTWAIT flag to send(); or
• setting a send timeout with the SO_SNDTIMEO socket option.

Append a \r\n to the string to put the text on a new line.

textBox1.Text += ("brown\r\n");
textBox1.Text += ("brwn");

This will produce the two entries on separate lines.

When you run your form and you want showing text in textbox is clear so you put the code : -

textBox1.text = String.Empty;

Where textBox1 is your textbox name.

you can use $nbsp; for a single space, if you like just using single allows you single space instead of using creating own class

    <div id="bulkOptionContainer" class="col-xs-4">
        <select class="form-control" name="" id="">
            <option value="">Select Options</option>
            <option value="">Published</option>
            <option value="">Draft</option>
            <option value="">Delete</option>
        </select>
    </div>

    <div class="col-xs-4">

        <input type="submit" name="submit" class="btn btn-success " value="Apply">

DEMO

I got the same error because I had accidentally used <div> instead of <canvas> as the element on which I attempt to call getContext.

Try this:

import time
while True:
    print("Hi ", end="\r")
    time.sleep(1)
    print("Bob", end="\r")
    time.sleep(1)

It worked for me. The end="\r" part is making it overwrite the previous line.

WARNING!

If you print out hi, then print out hello using \r, you’ll get hillo because the output wrote over the previous two letters. If you print out hi with spaces (which don’t show up here), then it will output hi. To fix this, print out spaces using \r.

You're not actually returning anything from your run_cmd function.

function run_cmd(cmd, args, done) {
    var spawn = require("child_process").spawn;
    var child = spawn(cmd, args);
    var result = { stdout: "" };
    child.stdout.on("data", function (data) {
            result.stdout += data;
    });
    child.stdout.on("end", function () {
            done();
    });
    return result;
}

> foo = run_cmd("ls", ["-al"], function () { console.log("done!"); });
{ stdout: '' }
done!
> foo.stdout
'total 28520...'

Works just fine. :)

This can be done without terminal, directly from IDE. Netbeans, for example.

1. Create a separate project with packages (Create Project - Java - Java Class Library).
2. Put your .java classes there.
3. Build this project.
4. Go to your project folder and find build and dist folders there.
5. Find .jar file in your dist folder.
6. Get your other project and add this .jar file to project libraries.
7. You can now reference classes from this library and its methods directly from code, if import is automatically done for you.

What you're doing is creating a temporary. That temporary exists in a scope determined by the compiler, such that it's long enough to satisfy the requirements of where it's going.

As soon as the statement const char* cstr2 = ss.str().c_str(); is complete, the compiler sees no reason to keep the temporary string around, and it's destroyed, and thus your const char * is pointing to free'd memory.

Your statement string str(ss.str()); means that the temporary is used in the constructor for the string variable str that you've put on the local stack, and that stays around as long as you'd expect: until the end of the block, or function you've written. Therefore the const char * within is still good memory when you try the cout.

I've had this problem. See The Python "Connection Reset By Peer" Problem.

You have (most likely) run afoul of small timing issues based on the Python Global Interpreter Lock.

You can (sometimes) correct this with a time.sleep(0.01) placed strategically.

"Where?" you ask. Beats me. The idea is to provide some better thread concurrency in and around the client requests. Try putting it just before you make the request so that the GIL is reset and the Python interpreter can clear out any pending threads.

You can use extensions for this.

extension NSDate {
    //NSString to NSDate
    convenience
    init(dateString:String) {
        let nsDateFormatter = NSDateFormatter()
        nsDateFormatter.dateFormat = "yyyy-MM-dd hh:mm:ss"
        // Add the locale if required here
        let dateObj = nsDateFormatter.dateFromString(dateString)
        self.init(timeInterval:0, sinceDate:dateObj!)
    }

    //NSDate to time string
    func getTime() -> String {
        let timeFormatter = NSDateFormatter()
        timeFormatter.dateFormat = "hh:mm"
        //Can also set the default styles for date or time using .timeStyle or .dateStyle
        return timeFormatter.stringFromDate(self)
    }

    //NSDate to date string
    func getDate() -> String {
        let dateFormatter = NSDateFormatter()
        dateFormatter.dateFormat = "dd, MMM"
        return dateFormatter.stringFromDate(self)
    }

    //NSDate to String
    func getString() -> String {
        let dateFormatter = NSDateFormatter()
        dateFormatter.dateFormat = "yyyy-MM-dd hh:mm:ss"
        return dateFormatter.stringFromDate(self)
    }
}

So while execution actual code will look like follows

    var dateObjFromString = NSDate(dateString: cutDateTime)
    var dateString = dateObjFromString.getDate()
    var timeString = dateObjFromString.getTime()
    var stringFromDate = dateObjFromString.getString()

There are some defaults methods as well but I guess it might not work for the format you have given from documentation

    -dateFromString(_:)
    -stringFromDate(_:)
    -localizedStringFromDate(_ date: NSDate,
                     dateStyle dateStyle: NSDateFormatterStyle,
                     timeStyle timeStyle: NSDateFormatterStyle) -> String

For some Distributions, Cauchy I think, I have found that trapz will overestimate the area, and so the pdf will change depending on the number of bins you select. In which case I do

[N,h]=hist(q_f./theta,30000); % there Is a large range but most of the bins will be empty
plot(h,N/(sum(N)*mean(diff(h))),'+r')

I am using VS2012 and facing the same error. I removed the following Target tag from the .csproj file and it started compiling without any error.

Not sure if this is stopping everyone else, but I resolved this by upgrading chromedriver and then ensuring that it was in a place that my user could read from (it seems like a lot of people encountering this are seeing it for permission reasons like me).

On Ubuntu 16.04: 1. Download chromedriver (version 2.37 for me) 2. Unzip the file 3. Install it somewhere sensible (I chose /usr/local/bin/chromedriver)

Doesn't even need to be owned by my user as long as it's globally executable (sudo chmod +x /usr/local/bin/chromedriver)

In case of MySQL or SQLite the correct keyword is IFNULL (not ISNULL).

 SELECT iar.Description, 
      IFNULL(iai.Quantity,0) as Quantity, 
      IFNULL(iai.Quantity * rpl.RegularPrice,0) as 'Retail', 
      iar.Compliance 
    FROM InventoryAdjustmentReason iar
    LEFT OUTER JOIN InventoryAdjustmentItem iai  on (iar.Id = iai.InventoryAdjustmentReasonId)
    LEFT OUTER JOIN Item i on (i.Id = iai.ItemId)
    LEFT OUTER JOIN ReportPriceLookup rpl on (rpl.SkuNumber = i.SkuNo)
WHERE iar.StoreUse = 'yes'

Along with the SHA-1 id of the commit, date and time of the server time would have helped?

Something like this:

commit happened at 11:30:25 on 19 aug 2013 would show as 6886bbb7be18e63fc4be68ba41917b48f02e09d7_19aug2013_113025

Try to change your label frame size height and width so your text not cut.

 [label setframe:CGRect(x,y,widht,height)];

One of the fundamental principles behind a promise is that it's handled asynchronously. This means that you cannot create a promise and then immediately use its result synchronously in your code (e.g. it's not possible to return the result of a promise from within the function that initiated the promise).

What you likely want to do instead is to return the entire promise itself. Then whatever function needs its result can call .then() on the promise, and the result will be there when the promise has been resolved.

Here is a resource from HTML5Rocks that goes over the lifecycle of a promise, and how its output is resolved asynchronously:
http://www.html5rocks.com/en/tutorials/es6/promises/

Create a new keypair: (go with the defaults)

ssh-keygen

Copy the public key to the server: (password for the last time)

ssh-copy-id [email protected]

From now on the server should recognize your key and not ask you for the password anymore:

ssh [email protected]

In my case ASP.NET State Service was stopped. Changing the Startup type to Automatic and starting the service manually for the first time solved the issue.

it's because you are trying to launch your app from an activity that is not launcher activity. try run it from launcher activity or change your current activity category to launcher in android Manifest.

There are some inherent problems with date parsing that are unfortunately not addressed well by default.

-Human readable dates have implicit timezone in them
-There are many widely used date formats around the web that are ambiguous

To solve these problems easy and clean one would need a function like this:

>parse(whateverDateTimeString,expectedDatePattern,timezone)
"unix time in milliseconds"

I have searched for this, but found nothing like that!

So I created: https://github.com/zsoltszabo/timestamp-grabber

Enjoy!

I would suggest using R and the package RSQLite

#install.packages("RSQLite") #perhaps needed
library("RSQLite")

# connect to the sqlite file
sqlite    <- dbDriver("SQLite")
exampledb <- dbConnect(sqlite,"database.sqlite")

dbListTables(exampledb)

Building on top of what Finesse wrote, here is a simpler way to target the svg and change it's gradient.

This is what you need to do:

1. Assign classes to each color stop defined in the gradient element.
2. Target the css and change the stop-color for each of those stops using plain classes.
3. Win!

Some benefits of using classes instead of :nth-child is that it'll not be affected if you reorder your stops. Also, it makes the intent of each class clear - you'll be left wondering whether you needed a blue color on the first child or the second one.

I've tested it on all Chrome, Firefox and IE11:

.main-stop {_x000D_
  stop-color: red;_x000D_
}_x000D_
.alt-stop {_x000D_
  stop-color: green;_x000D_
}

<svg class="green" width="100" height="50" version="1.1" xmlns="http://www.w3.org/2000/svg">_x000D_
  <linearGradient id="gradient">_x000D_
    <stop class="main-stop" offset="0%" />_x000D_
    <stop class="alt-stop" offset="100%" />_x000D_
  </linearGradient>_x000D_
  <rect width="100" height="50" fill="url(#gradient)" />_x000D_
</svg>

See an editable example here: https://jsbin.com/gabuvisuhe/edit?html,css,output

Assuming you have a button with the id button, try this example:

$("#button").click(function() {
    $([document.documentElement, document.body]).animate({
        scrollTop: $("#elementtoScrollToID").offset().top
    }, 2000);
});

I got the code from the article Smoothly scroll to an element without a jQuery plugin. And I have tested it on the example below.

<html>_x000D_
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.5.1/jquery.min.js"></script>_x000D_
    <script>_x000D_
        $(document).ready(function (){_x000D_
            $("#click").click(function (){_x000D_
                $('html, body').animate({_x000D_
                    scrollTop: $("#div1").offset().top_x000D_
                }, 2000);_x000D_
            });_x000D_
        });_x000D_
    </script>_x000D_
    <div id="div1" style="height: 1000px; width 100px">_x000D_
        Test_x000D_
    </div>_x000D_
    <br/>_x000D_
    <div id="div2" style="height: 1000px; width 100px">_x000D_

Please note that using StringFormat in Bindings only seems to work for "text" properties. Using this for Label.Content will not work

Please people don't give up your old habits just yet. There is a large difference in speed between allocating memory once then working with the entries in that array (as of old), and allocating it many times as an array grows (which is inevitably what the system does under the hood with other suggested methods).

None of this matters of course, until you want to do something cool with larger arrays. Then it does.

Seeing as there still seems to be no option in JS at the moment to set the initial capacity of an array, I use the following...

var newArrayWithSize = function(size) {
  this.standard = this.standard||[];
  for (var add = size-this.standard.length; add>0; add--) {
   this.standard.push(undefined);// or whatever
  }
  return this.standard.slice(0,size);
}

There are tradeoffs involved:

• This method takes as long as the others for the first call to the function, but very little time for later calls (unless asking for a bigger array).
• The standard array does permanently reserve as much space as the largest array you have asked for.

But if it fits with what you're doing there can be a payoff. Informal timing puts

for (var n=10000;n>0;n--) {var b = newArrayWithSize(10000);b[0]=0;}

at pretty speedy (about 50ms for the 10000 given that with n=1000000 it took about 5 seconds), and

for (var n=10000;n>0;n--) {
  var b = [];for (var add=10000;add>0;add--) {
    b.push(undefined);
  }
}

at well over a minute (about 90 sec for the 10000 on the same chrome console, or about 2000 times slower). That won't just be the allocation, but also the 10000 pushes, for loop, etc..

I’ve been struggling with this for a while now. Dycey’s solution is correct in that specifying the src multiple times outputs the same thing in your css file. However, this seems to break in OSX Firefox 23 (probably other versions too, but I don’t have time to test).

The cross-browser @font-face solution from Font Squirrel looks like this:

@font-face {
    font-family: 'fontname';
    src: url('fontname.eot');
    src: url('fontname.eot?#iefix') format('embedded-opentype'),
         url('fontname.woff') format('woff'),
         url('fontname.ttf') format('truetype'),
         url('fontname.svg#fontname') format('svg');
    font-weight: normal;
    font-style: normal;
}

To produce the src property with the comma-separated values, you need to write all of the values on one line, since line-breaks are not supported in Sass. To produce the above declaration, you would write the following Sass:

@font-face
  font-family: 'fontname'
  src: url('fontname.eot')
  src: url('fontname.eot?#iefix') format('embedded-opentype'), url('fontname.woff') format('woff'), url('fontname.ttf') format('truetype'), url('fontname.svg#fontname') format('svg')
  font-weight: normal
  font-style: normal

I think it seems silly to write out the path a bunch of times, and I don’t like overly long lines in my code, so I worked around it by writing this mixin:

=font-face($family, $path, $svg, $weight: normal, $style: normal)
  @font-face
    font-family: $family
    src: url('#{$path}.eot')
    src: url('#{$path}.eot?#iefix') format('embedded-opentype'), url('#{$path}.woff') format('woff'), url('#{$path}.ttf') format('truetype'), url('#{$path}.svg##{$svg}') format('svg')
    font-weight: $weight
    font-style: $style

Usage: For example, I can use the previous mixin to setup up the Frutiger Light font like this:

+font-face('frutigerlight', '../fonts/frutilig-webfont', 'frutigerlight')

You can use Process.killProcess(Process.myPid()); to kill your app, but maybe it is not safe? I didn't encounter any problem or crash after I used this method and after I used this, the process of my app in the DDMS list disappeared.

If you need to mock a static method, it is a strong indicator for a bad design. Usually, you mock the dependency of your class-under-test. If your class-under-test refers to a static method - like java.util.Math#sin for example - it means the class-under-test needs exactly this implementation (of accuracy vs. speed for example). If you want to abstract from a concrete sinus implementation you probably need an Interface (you see where this is going to)?

1. Install Style Loader and CSS Loader:

   npm install --save-dev style-loader
   npm install --save-dev css-loader
   

2. Configure webpack

   module: {
           loaders: [
               {
                   test: /\.css$/,
                   loader: 'style-loader'
               }, {
                   test: /\.css$/,
                   loader: 'css-loader',
                   query: {
                       modules: true,
                       localIdentName: '[name]__[local]___[hash:base64:5]'
                   }
               }
           ]
       }
   

You are using datetimepicker when it should be datepicker. As per the docs. Try this and it should work.

<script type="text/javascript">
  $(function () {
    $('#datetimepicker9').datepicker({
      viewMode: 'years'
    });
  });
 </script>

WinForms

Add an event handler for the Control.DoubleClick event for your ListBox, and in that event handler open up a MessageBox displaying the selected item.

E.g.:

 private void ListBox1_DoubleClick(object sender, EventArgs e)
 {
     if (ListBox1.SelectedItem != null)
     {
         MessageBox.Show(ListBox1.SelectedItem.ToString());
     }
 }

Where ListBox1 is the name of your ListBox.

Note that you would assign the event handler like this:

ListBox1.DoubleClick += new EventHandler(ListBox1_DoubleClick);

WPF
Pretty much the same as above, but you'd use the MouseDoubleClick event instead:

ListBox1.MouseDoubleClick += new RoutedEventHandler(ListBox1_MouseDoubleClick);

And the event handler:

 private void ListBox1_MouseDoubleClick(object sender, RoutedEventArgs e)
 {
     if (ListBox1.SelectedItem != null)
     {
         MessageBox.Show(ListBox1.SelectedItem.ToString());
     }
 }

Edit: Sisya's answer checks to see if the double-click occurred over an item, which would need to be incorporated into this code to fix the issue mentioned in the comments (MessageBox shown if ListBox is double-clicked while an item is selected, but not clicked over an item).

Hope this helps!

Occasionally when a disk runs out of space, the message "transaction log for database XXXXXXXXXX is full due to 'LOG_BACKUP'" will be returned when an update SQL statement fails. Check your diskspace :)

As Chris Lutz mentioned, this is defined by the __repr__ method in your class.

From the documentation of repr():

For many types, this function makes an attempt to return a string that would yield an object with the same value when passed to eval(), otherwise the representation is a string enclosed in angle brackets that contains the name of the type of the object together with additional information often including the name and address of the object. A class can control what this function returns for its instances by defining a __repr__() method.

Given the following class Test:

class Test:
    def __init__(self, a, b):
        self.a = a
        self.b = b

    def __repr__(self):
        return "<Test a:%s b:%s>" % (self.a, self.b)

    def __str__(self):
        return "From str method of Test: a is %s, b is %s" % (self.a, self.b)

..it will act the following way in the Python shell:

>>> t = Test(123, 456)
>>> t
<Test a:123 b:456>
>>> print repr(t)
<Test a:123 b:456>
>>> print(t)
From str method of Test: a is 123, b is 456
>>> print(str(t))
From str method of Test: a is 123, b is 456

If no __str__ method is defined, print(t) (or print(str(t))) will use the result of __repr__ instead

If no __repr__ method is defined then the default is used, which is pretty much equivalent to..

def __repr__(self):
    return "<%s instance at %s>" % (self.__class__.__name__, id(self))

All that is needed is "#,0.00", c# does the rest.

Num.ToString("#,0.00"")

• The "#,0" formats the thousand separators
• "0.00" forces two decimal points

Incase you are dynamically getting your data e.g When you need data based on the user logged in by their id use consider the following code example for a No Active Record:

 $this->db->query('SELECT * FROM my_users_table WHERE id = ?', $this->session->userdata('id'));

 return $query->row_array();

This will return a specific row based on your the set session data of user.

Your question says "Internet Explorer," but for those interested in other browsers, you can now use all: unset on buttons to unstyle them.

It doesn't work in IE, but it's well-supported everywhere else.

https://caniuse.com/#feat=css-all

Old Safari color warning: Setting the text color of the button after using all: unset can fail in Safari 13.1, due to a bug in WebKit. (The bug is fixed in Safari 14 and up.) "all: unset is setting -webkit-text-fill-color to black, and that overrides color." If you need to set text color after using all: unset, be sure to set both the color and the -webkit-text-fill-color to the same color.

Accessibility warning: For the sake of users who aren't using a mouse pointer, be sure to re-add some :focus styling, e.g. button:focus { outline: orange auto 5px } for keyboard accessibility.

And don't forget cursor: pointer. all: unset removes all styling, including the cursor: pointer, which makes your mouse cursor look like a pointing hand when you hover over the button. You almost certainly want to bring that back.

button {
  all: unset;
  color: blue;
  -webkit-text-fill-color: blue;
  cursor: pointer;
}

button:focus {
  outline: orange 5px auto;
}

<button>check it out</button>

You can try Context.getApplicationInfo().dataDir if you want the package's persistent data folder.

getFilesDir() returns a subroot of this.

The directive can access any attribute that is defined on the same element, even if the directive itself is not the element.

Template:

<div example-directive example-number="99" example-function="exampleCallback()"></div>

Directive:

app.directive('exampleDirective ', function () {
    return {
        restrict: 'A',   // 'A' is the default, so you could remove this line
        scope: {
            callback : '&exampleFunction',
        },
        link: function (scope, element, attrs) {
            var num = scope.$eval(attrs.exampleNumber);
            console.log('number=',num);
            scope.callback();  // calls exampleCallback()
        }
    };
});

fiddle

If the value of attribute example-number will be hard-coded, I suggest using $eval once, and storing the value. Variable num will have the correct type (a number).

This works for me

# Convert image to bytes
import PIL.Image as Image
pil_im = Image.fromarray(image)
b = io.BytesIO()
pil_im.save(b, 'jpeg')
im_bytes = b.getvalue()
return im_bytes

Use the gca ("get current axes") helper function:

ax = plt.gca()

Example:

import matplotlib.pyplot as plt
import matplotlib.finance
quotes = [(1, 5, 6, 7, 4), (2, 6, 9, 9, 6), (3, 9, 8, 10, 8), (4, 8, 8, 9, 8), (5, 8, 11, 13, 7)]
ax = plt.gca()
h = matplotlib.finance.candlestick(ax, quotes)
plt.show()

    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

also works. First create a JFrame called frame, then add this code underneath.

You can use the split() function, which returns a list, to separate them.

letters = 'QH QD JC KD JS'

letters_list = letters.split()

Printing letters_list would now format it like this:

['QH', 'QD', 'JC', 'KD', 'JS']

Now you have a list that you can work with, just like you would with any other list. For example accessing elements based on indexes:

print(letters_list[2])

This would print the third element of your list, which is 'JC'

I as well had the same problem and nearly drove crazy. The solution was pretty unexpected.

My Excel is shipped out by default that I enter formulas in an Excel-Cell as followed:

=COUNTIF(Range; Searchvalue)
=COUNTIF(A1:A10; 7) 'Example

Please note, that parameters are separated with a semicolon;. Now if you paste exactly that string into a formula within VBA, for example like:

Range("C7").FormulaArray = "=COUNTIF(A1:A10; 7)" 'this will not work

You will get this 1004-error with absolutely no explanation. I spent hours to debug this.. All you have to do is replace all semicolon with commas.

Range("C7").FormulaArray = "=COUNTIF(A1:A10, 7)" 'this works

The one thing that finally worked for me on Mac was upgrading from node 8.12 to 10.x using NVM.

I uninstalled all other versions of Node with NVM, then installed 10.x, then ran nvm alias default node, which tells NVM to always default to the latest available node version on a shell.

After that, my live reloading issue went away!

this.form.submit();

This is probably your best bet. Especially if you are not already using jQuery in your project, there is no need to add it (or any other JS library) just for this purpose.

If anyone just wants to validate a bearer token in the authorize phase using the current security practices you can,

add this to your Startup/ConfigureServices

    services.AddSingleton<IAuthorizationHandler, BearerAuthorizationHandler>();
    services.AddAuthentication(JwtBearerDefaults.AuthenticationScheme).AddJwtBearer();

    services.AddAuthorization(options => options.AddPolicy("Bearer",
        policy => policy.AddRequirements(new BearerRequirement())
        )
    );

and this in your codebase,

public class BearerRequirement : IAuthorizationRequirement
{
    public async Task<bool> IsTokenValid(SomeValidationContext context, string token)
    {
        // here you can check if the token received is valid 
        return true;
    }
}

public class BearerAuthorizationHandler : AuthorizationHandler<BearerRequirement> 
{

    public BearerAuthorizationHandler(SomeValidationContext thatYouCanInject)
    {
       ...
    }

    protected override async Task HandleRequirementAsync(AuthorizationHandlerContext context, BearerRequirement requirement)
    {
        var authFilterCtx = (Microsoft.AspNetCore.Mvc.Filters.AuthorizationFilterContext)context.Resource;
        string authHeader = authFilterCtx.HttpContext.Request.Headers["Authorization"];
        if (authHeader != null && authHeader.Contains("Bearer"))
        {
            var token = authHeader.Replace("Bearer ", string.Empty);
            if (await requirement.IsTokenValid(thatYouCanInject, token))
            {
                context.Succeed(requirement);
            }
        }
    }
}

If the code doesn't reach context.Succeed(...) it will Fail anyway (401).

And then in your controllers you can use

 [Authorize(Policy = "Bearer", AuthenticationSchemes = JwtBearerDefaults.AuthenticationScheme)]

change p:suffix=".jsp" value acordingly otherwise we can develope custom view resolver

As @Hellfrost pointed out, it is literally nonsense to compare a number to two different numbers in "one operation", and I know of no C# operator that encapsulates this.

between = (0 < 5 && 5 < 10);

Is about the most-compact form I can think of.

You could make a somewhat "fluent"-looking method using extension (though, while amusing, I think it's overkill):

public static bool Between(this int x, int a, int b)
{
    return (a < x) && (x < b);
}

Use:

int x = 5;
bool b = x.Between(0,10);

Here's an extremely simple answer

  theme(
    panel.border = element_blank(), 
    panel.grid.major = element_blank(),
    panel.grid.minor = element_blank(), 
    axis.line = element_line(colour = "black")
    )

It's that easy. Source: the end of this article

This is the modified version that I put in my code (I'm using .Net 4.5) but I think it should work on 4.0 too.

public void AppendText(string text, Color color, bool addNewLine = false)
{
        box.SuspendLayout();
        box.SelectionColor = color;
        box.AppendText(addNewLine
            ? $"{text}{Environment.NewLine}"
            : text);
        box.ScrollToCaret();
        box.ResumeLayout();
}

Differences with original one:

• possibility to add text to a new line or simply append it
• no need to change selection, it works the same
• inserted ScrollToCaret to force autoscroll
• added suspend/resume layout calls

Starting from Visual Studio 2017 (15.9.4) there is an option:

Tools->Options->Debugging->Automatically close the console

The corresponding fragment from the Visual Studio documentation:

Automatically close the console when debugging stops:

Tells Visual Studio to close the console at the end of a debugging session.

What I would do:

char c;
int cint;
for(int n = 0; n < str.length(); n ++;)
{
    c = str.charAt(n);
    cint = (int)c;
    if(cint <48 || (cint > 57 && cint < 65) || (cint > 90 && cint < 97) || cint > 122)
    {
        specialCharacterCount++
    }
}

That is a simple way to do things, without having to import any special classes. Stick it in a method, or put it straight into the main code.

I stumbled over the same issue and found a nice solution which does not need any static ip configuration:

You can access a service via it's DNS name (as mentioned by you): servicename.namespace.svc.cluster.local

You can use that DNS name to reference it in another namespace via a local service:

kind: Service
apiVersion: v1
metadata:
  name: service-y
  namespace: namespace-a
spec:
  type: ExternalName
  externalName: service-x.namespace-b.svc.cluster.local
  ports:
  - port: 80

Check that right version is referenced in your project. E.g. the dll it is complaining about, could be from an older version and that's why there could be a version mismatch.

After adding JTextArea into JScrollPane here:

scroll = new JScrollPane(display);

You don't need to add it again into other container like you do:

middlePanel.add(display);

Just remove that last line of code and it will work fine. Like this:

    middlePanel=new JPanel();
    middlePanel.setBorder(new TitledBorder(new EtchedBorder(), "Display Area"));

    // create the middle panel components

    display = new JTextArea(16, 58);
    display.setEditable(false); // set textArea non-editable
    scroll = new JScrollPane(display);
    scroll.setVerticalScrollBarPolicy(ScrollPaneConstants.VERTICAL_SCROLLBAR_ALWAYS);

    //Add Textarea in to middle panel
    middlePanel.add(scroll);

JScrollPane is just another container that places scrollbars around your component when its needed and also has its own layout. All you need to do when you want to wrap anything into a scroll just pass it into JScrollPane constructor:

new JScrollPane( myComponent ) 

or set view like this:

JScrollPane pane = new JScrollPane ();
pane.getViewport ().setView ( myComponent );

Additional:

Here is fully working example since you still did not get it working:

public static void main ( String[] args )
{
    JPanel middlePanel = new JPanel ();
    middlePanel.setBorder ( new TitledBorder ( new EtchedBorder (), "Display Area" ) );

    // create the middle panel components

    JTextArea display = new JTextArea ( 16, 58 );
    display.setEditable ( false ); // set textArea non-editable
    JScrollPane scroll = new JScrollPane ( display );
    scroll.setVerticalScrollBarPolicy ( ScrollPaneConstants.VERTICAL_SCROLLBAR_ALWAYS );

    //Add Textarea in to middle panel
    middlePanel.add ( scroll );

    // My code
    JFrame frame = new JFrame ();
    frame.add ( middlePanel );
    frame.pack ();
    frame.setLocationRelativeTo ( null );
    frame.setVisible ( true );
}

And here is what you get:

std::map<Key, Value> ? SortedDictionary<TKey, TValue>

std::unordered_map<Key, Value> ? Dictionary<TKey, TValue>
