Another problem solved by the rubber duck:
The css is right but you still have to remember that the HTML elements order matters: the div has to come before the header. http://jsfiddle.net/Fq2Na/1/
Change your HTML code to have the div before the header:
<section>
<div><button>button</button></div>
<h1>some long long long long header, a whole line, 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6</h1>
</section>
And keep your CSS to the simple div { float: right; }
.
this one works for me (plain javascript)
var fixScroll = function (className, border) { // className = class of scrollElement(s), border: borderTop + borderBottom, due to offsetHeight
var reg = new RegExp(className,"i"); var off = +border + 1;
function _testClass(e) { var o = e.target; while (!reg.test(o.className)) if (!o || o==document) return false; else o = o.parentNode; return o;}
document.ontouchmove = function(e) { var o = _testClass(e); if (o) { e.stopPropagation(); if (o.scrollTop == 0) { o.scrollTop += 1; e.preventDefault();}}}
document.ontouchstart = function(e) { var o = _testClass(e); if (o && o.scrollHeight >= o.scrollTop + o.offsetHeight - off) o.scrollTop -= off;}
}
fixScroll("fixscroll",2); // assuming I have a 1px border in my DIV
html:
<div class="fixscroll" style="border:1px gray solid">content</div>
Of cause it's possible to create dynamic classes using very cool ExpandoObject class. But recently I worked on project and faced that Expando Object is serealized in not the same format on xml as an simple Anonymous class, it was pity =( , that is why I decided to create my own class and share it with you. It's using reflection and dynamic directive , builds Assembly, Class and Instance truly dynamicly. You can add, remove and change properties that is included in your class on fly Here it is :
using System;
using System.Collections.Generic;
using System.Linq;
using System.Reflection;
using System.Reflection.Emit;
using static YourNamespace.DynamicTypeBuilderTest;
namespace YourNamespace
{
/// This class builds Dynamic Anonymous Classes
public class DynamicTypeBuilderTest
{
///
/// Create instance based on any Source class as example based on PersonalData
///
public static object CreateAnonymousDynamicInstance(PersonalData personalData, Type dynamicType, List<ClassDescriptorKeyValue> classDescriptionList)
{
var obj = Activator.CreateInstance(dynamicType);
var propInfos = dynamicType.GetProperties();
classDescriptionList.ForEach(x => SetValueToProperty(obj, propInfos, personalData, x));
return obj;
}
private static void SetValueToProperty(object obj, PropertyInfo[] propInfos, PersonalData aisMessage, ClassDescriptorKeyValue description)
{
propInfos.SingleOrDefault(x => x.Name == description.Name)?.SetValue(obj, description.ValueGetter(aisMessage), null);
}
public static dynamic CreateAnonymousDynamicType(string entityName, List<ClassDescriptorKeyValue> classDescriptionList)
{
AssemblyName asmName = new AssemblyName();
asmName.Name = $"{entityName}Assembly";
AssemblyBuilder assemblyBuilder = AssemblyBuilder.DefineDynamicAssembly(asmName, AssemblyBuilderAccess.RunAndCollect);
ModuleBuilder moduleBuilder = assemblyBuilder.DefineDynamicModule($"{asmName.Name}Module");
TypeBuilder typeBuilder = moduleBuilder.DefineType($"{entityName}Dynamic", TypeAttributes.Public);
classDescriptionList.ForEach(x => CreateDynamicProperty(typeBuilder, x));
return typeBuilder.CreateTypeInfo().AsType();
}
private static void CreateDynamicProperty(TypeBuilder typeBuilder, ClassDescriptorKeyValue description)
{
CreateDynamicProperty(typeBuilder, description.Name, description.Type);
}
///
///Creation Dynamic property (from MSDN) with some Magic
///
public static void CreateDynamicProperty(TypeBuilder typeBuilder, string name, Type propType)
{
FieldBuilder fieldBuider = typeBuilder.DefineField($"{name.ToLower()}Field",
propType,
FieldAttributes.Private);
PropertyBuilder propertyBuilder = typeBuilder.DefineProperty(name,
PropertyAttributes.HasDefault,
propType,
null);
MethodAttributes getSetAttr =
MethodAttributes.Public | MethodAttributes.SpecialName |
MethodAttributes.HideBySig;
MethodBuilder methodGetBuilder =
typeBuilder.DefineMethod($"get_{name}",
getSetAttr,
propType,
Type.EmptyTypes);
ILGenerator methodGetIL = methodGetBuilder.GetILGenerator();
methodGetIL.Emit(OpCodes.Ldarg_0);
methodGetIL.Emit(OpCodes.Ldfld, fieldBuider);
methodGetIL.Emit(OpCodes.Ret);
MethodBuilder methodSetBuilder =
typeBuilder.DefineMethod($"set_{name}",
getSetAttr,
null,
new Type[] { propType });
ILGenerator methodSetIL = methodSetBuilder.GetILGenerator();
methodSetIL.Emit(OpCodes.Ldarg_0);
methodSetIL.Emit(OpCodes.Ldarg_1);
methodSetIL.Emit(OpCodes.Stfld, fieldBuider);
methodSetIL.Emit(OpCodes.Ret);
propertyBuilder.SetGetMethod(methodGetBuilder);
propertyBuilder.SetSetMethod(methodSetBuilder);
}
public class ClassDescriptorKeyValue
{
public ClassDescriptorKeyValue(string name, Type type, Func<PersonalData, object> valueGetter)
{
Name = name;
ValueGetter = valueGetter;
Type = type;
}
public string Name;
public Type Type;
public Func<PersonalData, object> ValueGetter;
}
///
///Your Custom class description based on any source class for example
/// PersonalData
public static IEnumerable<ClassDescriptorKeyValue> GetAnonymousClassDescription(bool includeAddress, bool includeFacebook)
{
yield return new ClassDescriptorKeyValue("Id", typeof(string), x => x.Id);
yield return new ClassDescriptorKeyValue("Name", typeof(string), x => x.FirstName);
yield return new ClassDescriptorKeyValue("Surname", typeof(string), x => x.LastName);
yield return new ClassDescriptorKeyValue("Country", typeof(string), x => x.Country);
yield return new ClassDescriptorKeyValue("Age", typeof(int?), x => x.Age);
yield return new ClassDescriptorKeyValue("IsChild", typeof(bool), x => x.Age < 21);
if (includeAddress)
yield return new ClassDescriptorKeyValue("Address", typeof(string), x => x?.Contacts["Address"]);
if (includeFacebook)
yield return new ClassDescriptorKeyValue("Facebook", typeof(string), x => x?.Contacts["Facebook"]);
}
///
///Source Data Class for example
/// of cause you can use any other class
public class PersonalData
{
public int Id { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
public string Country { get; set; }
public int Age { get; set; }
public Dictionary<string, string> Contacts { get; set; }
}
}
}
It is also very simple to use DynamicTypeBuilder, you just need put few lines like this:
public class ExampleOfUse
{
private readonly bool includeAddress;
private readonly bool includeFacebook;
private readonly dynamic dynamicType;
private readonly List<ClassDescriptorKeyValue> classDiscriptionList;
public ExampleOfUse(bool includeAddress = false, bool includeFacebook = false)
{
this.includeAddress = includeAddress;
this.includeFacebook = includeFacebook;
this.classDiscriptionList = DynamicTypeBuilderTest.GetAnonymousClassDescription(includeAddress, includeFacebook).ToList();
this.dynamicType = DynamicTypeBuilderTest.CreateAnonymousDynamicType("VeryPrivateData", this.classDiscriptionList);
}
public object Map(PersonalData privateInfo)
{
object dynamicObject = DynamicTypeBuilderTest.CreateAnonymousDynamicInstance(privateInfo, this.dynamicType, classDiscriptionList);
return dynamicObject;
}
}
I hope that this code snippet help somebody =) Enjoy!
You can use the utility method in Collections
class
public static <T extends Comparable<? super T>> void sort(List<T> list)
or
public static <T> void sort(List<T> list,Comparator<? super T> c)
Refer to Comparable
and Comparator
interfaces for more flexibility on sorting the object.
In cases where I don't care whether the variable is undef
or equal to ''
, I usually summarize it as:
$name = "" unless defined $name;
if($name ne '') {
# do something with $name
}
You can't apply a keypair to a running instance. You can only use the new keypair to launch a new instance.
For recovery, if it's an EBS boot AMI, you can stop it, make a snapshot of the volume. Create a new volume based on it. And be able to use it back to start the old instance, create a new image, or recover data.
Though data at ephemeral storage will be lost.
Due to the popularity of this question and answer, I wanted to capture the information in the link that Rodney posted on his comment.
Credit goes to Eric Hammond for this information.
You can examine and edit files on the root EBS volume on an EC2 instance even if you are in what you considered a disastrous situation like:
On a physical computer sitting at your desk, you could simply boot the system with a CD or USB stick, mount the hard drive, check out and fix the files, then reboot the computer to be back in business.
A remote EC2 instance, however, seems distant and inaccessible when you are in one of these situations. Fortunately, AWS provides us with the power and flexibility to be able to recover a system like this, provided that we are running EBS boot instances and not instance-store.
The approach on EC2 is somewhat similar to the physical solution, but we’re going to move and mount the faulty “hard drive” (root EBS volume) to a different instance, fix it, then move it back.
In some situations, it might simply be easier to start a new EC2 instance and throw away the bad one, but if you really want to fix your files, here is the approach that has worked for many:
Setup
Identify the original instance (A) and volume that contains the broken root EBS volume with the files you want to view and edit.
instance_a=i-XXXXXXXX
volume=$(ec2-describe-instances $instance_a |
egrep '^BLOCKDEVICE./dev/sda1' | cut -f3)
Identify the second EC2 instance (B) that you will use to fix the files on the original EBS volume. This instance must be running in the same availability zone as instance A so that it can have the EBS volume attached to it. If you don’t have an instance already running, start a temporary one.
instance_b=i-YYYYYYYY
Stop the broken instance A (waiting for it to come to a complete stop), detach the root EBS volume from the instance (waiting for it to be detached), then attach the volume to instance B on an unused device.
ec2-stop-instances $instance_a
ec2-detach-volume $volume
ec2-attach-volume --instance $instance_b --device /dev/sdj $volume
ssh to instance B and mount the volume so that you can access its file system.
ssh ...instance b...
sudo mkdir -p 000 /vol-a
sudo mount /dev/sdj /vol-a
Fix It
At this point your entire root file system from instance A is available for viewing and editing under /vol-a on instance B. For example, you may want to:
Note: The uids on the two instances may not be identical, so take care if you are creating, editing, or copying files that belong to non-root users. For example, your mysql user on instance A may have the same UID as your postfix user on instance B which could cause problems if you chown files with one name and then move the volume back to A.
Wrap Up
After you are done and you are happy with the files under /vol-a, unmount the file system (still on instance-B):
sudo umount /vol-a
sudo rmdir /vol-a
Now, back on your system with ec2-api-tools, continue moving the EBS volume back to it’s home on the original instance A and start the instance again:
ec2-detach-volume $volume
ec2-attach-volume --instance $instance_a --device /dev/sda1 $volume
ec2-start-instances $instance_a
Hopefully, you fixed the problem, instance A comes up just fine, and you can accomplish what you originally set out to do. If not, you may need to continue repeating these steps until you have it working.
Note: If you had an Elastic IP address assigned to instance A when you stopped it, you’ll need to reassociate it after starting it up again.
Remember! If your instance B was temporarily started just for this process, don’t forget to terminate it now.
See the above definition where it states that a callback function is passed off to some other function and at some point it is called.
In C++ it is desirable to have callback functions call a classes method. When you do this you have access to the member data. If you use the C way of defining a callback you will have to point it to a static member function. This is not very desirable.
Here is how you can use callbacks in C++. Assume 4 files. A pair of .CPP/.H files for each class. Class C1 is the class with a method we want to callback. C2 calls back to C1's method. In this example the callback function takes 1 parameter which I added for the readers sake. The example doesn't show any objects being instantiated and used. One use case for this implementation is when you have one class that reads and stores data into temporary space and another that post processes the data. With a callback function, for every row of data read the callback can then process it. This technique cuts outs the overhead of the temporary space required. It is particularly useful for SQL queries that return a large amount of data which then has to be post-processed.
/////////////////////////////////////////////////////////////////////
// C1 H file
class C1
{
public:
C1() {};
~C1() {};
void CALLBACK F1(int i);
};
/////////////////////////////////////////////////////////////////////
// C1 CPP file
void CALLBACK C1::F1(int i)
{
// Do stuff with C1, its methods and data, and even do stuff with the passed in parameter
}
/////////////////////////////////////////////////////////////////////
// C2 H File
class C1; // Forward declaration
class C2
{
typedef void (CALLBACK C1::* pfnCallBack)(int i);
public:
C2() {};
~C2() {};
void Fn(C1 * pThat,pfnCallBack pFn);
};
/////////////////////////////////////////////////////////////////////
// C2 CPP File
void C2::Fn(C1 * pThat,pfnCallBack pFn)
{
// Call a non-static method in C1
int i = 1;
(pThat->*pFn)(i);
}
@JsonSerialize and @JsonDeserialize worked fine for me. They eliminate the need to import the additional jsr310 module:
@JsonDeserialize(using = LocalDateDeserializer.class)
@JsonSerialize(using = LocalDateSerializer.class)
private LocalDate dateOfBirth;
Deserializer:
public class LocalDateDeserializer extends StdDeserializer<LocalDate> {
private static final long serialVersionUID = 1L;
protected LocalDateDeserializer() {
super(LocalDate.class);
}
@Override
public LocalDate deserialize(JsonParser jp, DeserializationContext ctxt)
throws IOException, JsonProcessingException {
return LocalDate.parse(jp.readValueAs(String.class));
}
}
Serializer:
public class LocalDateSerializer extends StdSerializer<LocalDate> {
private static final long serialVersionUID = 1L;
public LocalDateSerializer(){
super(LocalDate.class);
}
@Override
public void serialize(LocalDate value, JsonGenerator gen, SerializerProvider sp) throws IOException, JsonProcessingException {
gen.writeString(value.format(DateTimeFormatter.ISO_LOCAL_DATE));
}
}
type C:\temp\test.bat>C:\temp\test.log
I was working on something like this. But is working only with structures generated from proto. https://github.com/flowup-labs/grpc-utils
in your proto
message Msg {
Firstname string = 1 [(gogoproto.jsontag) = "name.firstname"];
PseudoFirstname string = 2 [(gogoproto.jsontag) = "lastname"];
EmbedMsg = 3 [(gogoproto.nullable) = false, (gogoproto.embed) = true];
Lastname string = 4 [(gogoproto.jsontag) = "name.lastname"];
Inside string = 5 [(gogoproto.jsontag) = "name.inside.a.b.c"];
}
message EmbedMsg{
Opt1 string = 1 [(gogoproto.jsontag) = "opt1"];
}
Then your output will be
{
"lastname": "Three",
"name": {
"firstname": "One",
"inside": {
"a": {
"b": {
"c": "goo"
}
}
},
"lastname": "Two"
},
"opt1": "var"
}
After various attempt, only this works well for me (under ios 8):
NSURLCache *cache = [[NSURLCache alloc] initWithMemoryCapacity:1 diskCapacity:1 diskPath:nil];
[NSURLCache setSharedURLCache:cache];
profile = webdriver.FirefoxProfile()
profile.set_preference('browser.window.width',0)
profile.set_preference('browser.window.height',0)
profile.update_preferences()
write this code into setup part of your test code, before the: webdriver.Firefox()
line.

This will resolve your problem.
Remote Debugging allows you to use the desktop dev-tools:
https://developers.google.com/chrome-developer-tools/docs/remote-debugging
If you ever need to send GET
request to an IP
as well as a Domain
(Other answers did not mention you can specify a port
variable), you can make use of this function:
function getCode(host, port, path, queryString) {
console.log("(" + host + ":" + port + path + ")" + "Running httpHelper.getCode()")
// Construct url and query string
const requestUrl = url.parse(url.format({
protocol: 'http',
hostname: host,
pathname: path,
port: port,
query: queryString
}));
console.log("(" + host + path + ")" + "Sending GET request")
// Send request
console.log(url.format(requestUrl))
http.get(url.format(requestUrl), (resp) => {
let data = '';
// A chunk of data has been received.
resp.on('data', (chunk) => {
console.log("GET chunk: " + chunk);
data += chunk;
});
// The whole response has been received. Print out the result.
resp.on('end', () => {
console.log("GET end of response: " + data);
});
}).on("error", (err) => {
console.log("GET Error: " + err);
});
}
Don't miss requiring modules at the top of your file:
http = require("http");
url = require('url')
Also bare in mind that you may use https
module for communicating over secured network. so these two lines would change:
https = require("https");
...
https.get(url.format(requestUrl), (resp) => { ......
Since you asked about ready-made Api's ... well Apache's commons. collections library has a CollectionUtils class that provides easy-to-use methods for Collection manipulation/checking, such as intersection, difference, and union.
They changed the switch statement (from C/Java/C++) behavior for c#. I guess the reasoning was that people forgot about the fall through and errors were caused. One book I read said to use goto to simulate, but this doesn't sound like a good solution to me.
Found a good solution what worked for me, check this link https://codepen.io/chriswrightdesign/pen/emQNGZ/?editors=1100 First, we add a parent div, second we change min-height:100% to min-height:100vh. It works like a charm.
// by having a parent with flex-direction:row,
// the min-height bug in IE doesn't stick around.
.flashy-content-outer {
display:flex;
flex-direction:row;
}
.flashy-content-inner {
display:flex;
flex-direction:column;
justify-content:center;
align-items:center;
min-width:100vw;
min-height:100vh;
padding:20px;
box-sizing:border-box;
}
.flashy-content {
display:inline-block;
padding:15px;

}
Solution #2 of @Ben's answer is not reproducible in other more generic examples. It happens to give the correct lookup in the example because the unique HouseType
in houses
appear in increasing order. Try this:
hous <- read.table(header = TRUE, stringsAsFactors = FALSE, text="HouseType HouseTypeNo
Semi 1
ECIIsHome 17
Single 2
Row 3
Single 2
Apartment 4
Apartment 4
Row 3")
largetable <- data.frame(HouseType = as.character(sample(unique(hous$HouseType), 1000, replace = TRUE)), stringsAsFactors = FALSE)
lookup <- unique(hous)
Bens solution#2 gives
housenames <- as.numeric(1:length(unique(hous$HouseType)))
names(housenames) <- unique(hous$HouseType)
base2 <- data.frame(HouseType = largetable$HouseType,
HouseTypeNo = (housenames[largetable$HouseType]))
which when
unique(base2$HouseTypeNo[ base2$HouseType=="ECIIsHome" ])
[1] 2
when the correct answer is 17 from the lookup table
The correct way to do it is
hous <- read.table(header = TRUE, stringsAsFactors = FALSE, text="HouseType HouseTypeNo
Semi 1
ECIIsHome 17
Single 2
Row 3
Single 2
Apartment 4
Apartment 4
Row 3")
largetable <- data.frame(HouseType = as.character(sample(unique(hous$HouseType), 1000, replace = TRUE)), stringsAsFactors = FALSE)
housenames <- tapply(hous$HouseTypeNo, hous$HouseType, unique)
base2 <- data.frame(HouseType = largetable$HouseType,
HouseTypeNo = (housenames[largetable$HouseType]))
Now the lookups are performed correctly
unique(base2$HouseTypeNo[ base2$HouseType=="ECIIsHome" ])
ECIIsHome
17
I tried to edit Bens answer but it gets rejected for reasons I cannot understand.
The $_post
function need the name value
like:
<input type="submit" value"Submit" name="example">

For Eclipse STS (3.5 at least) you don't need to install anything. Right click on schema.xsd -> Generate -> JAXB Classes. You'll have to specify the package & location in the next step and that's all, your classes should be generated. I guess all the above mentioned solutions work, but this seems by far the easiest (for STS users).
[UPDATE] Eclipse STS version 3.6 (based on Kepler) comes with the same functionality.
Here is an example that should help. If you have a timestamp with a timezone, you can convert that timestamp into any other timezone. If you haven't got a base timezone it won't be converted correctly.
SELECT now(),
now()::timestamp,
now() AT TIME ZONE 'CST',
now()::timestamp AT TIME ZONE 'CST'
Output:
-[ RECORD 1 ]---------------------------
now | 2018-09-15 17:01:36.399357+03
now | 2018-09-15 17:01:36.399357
timezone | 2018-09-15 08:01:36.399357
timezone | 2018-09-16 02:01:36.399357+03
If you want to keep the height of the DIV absolute, regardless of the amount of text inside use the following:
overflow: hidden;
Simple solution and understanding
To answer the question:
SELECT field,datetime_field
FROM database
WHERE TO_CHAR(date_field, 'YYYYMMDD') = TO_CHAR(SYSDATE-1, 'YYYYMMDD');
Some explanation
If you have a field that is not in date format but want to compare using date i.e. field is considered as date but in number format e.g. 20190823 (YYYYMMDD)
SELECT * FROM YOUR_TABLE WHERE ID_DATE = TO_CHAR(SYSDATE-1, 'YYYYMMDD')
If you have a field that is in date/timestamp format and you need to compare, Just change the format
SELECT TO_CHAR(SYSDATE-1, 'YYYY-MM-DD HH24:MI:SS') FROM DUAL
IF you want to return it to date format
SELECT TO_DATE(TO_CHAR(SYSDATE-1, 'YYYY-MM-DD HH24:MI:SS'), 'YYYY-MM-DD HH24:MI:SS') AS NEW_DATE FROM DUAL
Conclusion.
With this knowledge you can convert the filed you want to compare to a YYYYMMDD or YYYY-MM-DD or any year-month-date format then compare with the same sysdate format.

taskkill /F /PID
But it won't work for me
then I tried taskkill -PID <processorid> -F
Example:- taskkill -PID 33192 -F
Here 33192 is the processorid and it works
I had to add this line to settings.py in order to make it work (otherwise it showed an error when accessed from another computer)
ALLOWED_HOSTS = ['*']
then ran the server with:
python manage.py runserver 0.0.0.0:9595
Also ensure that the firewall allows connections to that port
@Value("${spring.profiles.active}")
private String activeProfile;
It works and you don't need to implement EnvironmentAware. But I don't know drawbacks of this approach.
Html.Action is a poorly designed technology. Because in your page Controller you can't receive the results of computation in your Partial Controller. Data flow is only Page Controller => Partial Controller.
To be closer to WebForm UserControl (*.ascx) you need to:
Create a page Model and a Partial Model
Place your Partial Model as a property in your page Model
In this situation you can use it like:
public class MyController : Controller
{
....
public MyController()
{
MyChildController = new MyControllerPartial(this.ViewData);
}
[HttpPost]
public ActionResult Index(MyPageViewModel model)
{
...
int childResult = MyChildController.ProcessSomething(model.MyPartialModel);
...
}
}
P.S. In step 3 you can use Html.Partial("PartialViewName", Model.MyPartialModel, <clone_ViewData_with_prefix_MyPartialModel>). For more details see ASP.NET MVC partial views: input name prefixes

If embed no longer works for you, try with /v
instead:
<iframe width="420" height="315" src="https://www.youtube.com/v/A6XUVjK9W4o" frameborder="0" allowfullscreen></iframe>
You can use :
const intersection = array1.filter(element => array2.includes(element));

There are a lot of helpful solutions out there, but there is no simplified way with extension. Here is the code to solve the issue with an extension:
extension UIImage {
var getWidth: CGFloat {
get {
let width = self.size.width
return width
}
}
var getHeight: CGFloat {
get {
let height = self.size.height
return height
}
}
}

I am very surprised that nobody here has mentioned the problem of connection and read timeout. It could happen (especially on Android and/or with some crappy network connectivity) that the request will hang and wait forever.
The following code (which also uses Apache IO Commons) takes this into account, and waits max. 5 seconds until it fails:
public static byte[] downloadFile(URL url)
{
try {
URLConnection conn = url.openConnection();
conn.setConnectTimeout(5000);
conn.setReadTimeout(5000);
conn.connect();
ByteArrayOutputStream baos = new ByteArrayOutputStream();
IOUtils.copy(conn.getInputStream(), baos);
return baos.toByteArray();
}
catch (IOException e)
{
// Log error and return null, some default or throw a runtime exception
}

It depends on wether the locatoin is detected by different DNS resolution from different locations, or by IP address that you are browsing from.
If its by DNS, you could just modify your hosts file to point at the server used in europe. Get your friend to ping the address, to see if its different from the one yours resolves to.
To browse from a different IP address:
You can rent a VPS server. You can use putty / SSH to act as a proxy. I use this from time to time to brows from the US using a VPS server I rent in the US.
Having an account on a remote host may or may not be enough. Sadly, my dreamhost account, even though I have ssh access, does not allow proxying.
You may also want to style textareas:
input::-webkit-input-placeholder, textarea::-webkit-input-placeholder {
color: #636363;
}
input:-moz-placeholder, textarea:-moz-placeholder {
color: #636363;
}
I created a function that might help. All it does is imitate the alert but put an image instead of text.
function alertImage(imgsrc) {
$('.d').css({
'position': 'absolute',
'top': '0',
'left': '50%',
'-webkit-transform': 'translate(-50%, 0)'
});
$('.d').animate({
opacity: 0
}, 0)
$('.d').animate({
opacity: 1,
top: "10px"
}, 250)
$('.d').append('An embedded page on this page says')
$('.d').append('<br><img src="' + imgsrc + '">')
$('.b').css({
'position':'absolute',
'-webkit-transform': 'translate(-100%, -100%)',
'top':'100%',
'left':'100%',
'display':'inline',
'background-color':'#598cbd',
'border-radius':'4px',
'color':'white',
'border':'none',
'width':'66',
'height':'33'
})
}
<script type="text/javascript" src="https://code.jquery.com/jquery-latest.min.js"></script>
<div class="d"><button onclick="$('.d').html('')" class="b">OK</button></div>

Use the truncate filter to cut off a string after limit is reached
{{ "Hello World!"|truncate(5) }} // default separator is ...
Hello...
You can also tell truncate to preserve whole words by setting the second parameter to true. If the last Word is on the the separator, truncate will print out the whole Word.
{{ "Hello World!"|truncate(7, true) }} // preserve words
Here Hello World!
If you want to change the separator, just set the third parameter to your desired separator.
{{ "Hello World!"|truncate(7, false, "??") }}
Hello W??
chars are just integers, so you can actually do a straight comparison of your character against literals:
if( c >= '0' && c <= '9' ){
This applies to all characters. See your ascii table.
ctype.h also provides functions to do this for you.

c:out
escapes HTML characters so that you can avoid cross-site scripting.
if person.name = <script>alert("Yo")</script>
the script will be executed in the second case, but not when using c:out
Try this, noting that the grammar of HTML is too complex for regular expressions to be correct 100% of the time:
var regex = /(<([^>]+)>)/ig
, body = "<p>test</p>"
, result = body.replace(regex, "");
console.log(result);
If you're willing to use a library such as jQuery, you could simply do this:
console.log($('<p>test</p>').text());
Calling Exception.ToString()
gives you more information than just using the Exception.Message
property. However, even this still leaves out lots of information, including:
Data
collection property found on all exceptions.There are times when you want to capture this extra information. The code below handles the above scenarios. It also writes out the properties of the exceptions in a nice order. It's using C# 7 but should be very easy for you to convert to older versions if necessary. See also this related answer.

Most people will be using this code for logging. Consider using Serilog with my Serilog.Exceptions NuGet package which also logs all properties of an exception but does it faster and without reflection in the majority of cases. Serilog is a very advanced logging framework which is all the rage at the time of writing.
You can use the Ben.Demystifier NuGet package to get human readable stack traces for your exceptions or the serilog-enrichers-demystify NuGet package if you are using Serilog.
See http://dev.mysql.com/doc/refman/8.0/en/numeric-types.html
INT
is a four-byte signed integer.
BIGINT
is an eight-byte signed integer.
They each accept no more and no fewer values than can be stored in their respective number of bytes. That means 232 values in an INT
and 264 values in a BIGINT
.
The 20 in INT(20)
and BIGINT(20)
means almost nothing. It's a hint for display width. It has nothing to do with storage, nor the range of values that column will accept.
Practically, it affects only the ZEROFILL
option:
CREATE TABLE foo ( bar INT(20) ZEROFILL );
INSERT INTO foo (bar) VALUES (1234);
SELECT bar from foo;
+----------------------+
| bar |
+----------------------+
| 00000000000000001234 |
+----------------------+
It's a common source of confusion for MySQL users to see INT(20)
and assume it's a size limit, something analogous to CHAR(20)
. This is not the case.
As you have to use WITH (NOLOCK) for each table it might be annoying to write it in every FROM or JOIN clause. However it has a reason why it is called a "dirty" read. So you really should know when you do one, and not set it as default for the session scope. Why?
Forgetting a WITH (NOLOCK) might not affect your program in a very dramatic way, however doing a dirty read where you do not want one can make the difference in certain circumstances.
So use WITH (NOLOCK) if the current data selected is allowed to be incorrect, as it might be rolled back later. This is mostly used when you want to increase performance, and the requirements on your application context allow it to take the risk that inconsistent data is being displayed. However you or someone in charge has to weigh up pros and cons of the decision of using WITH (NOLOCK).
You might like IntervalHeap from the C5 Generic Collection Library. To quote the user guide
Class
IntervalHeap<T>
implements interfaceIPriorityQueue<T>
using an interval heap stored as an array of pairs. TheFindMin
andFindMax
operations, and the indexer’s get-accessor, take time O(1). TheDeleteMin
,DeleteMax
, Add and Update operations, and the indexer’s set-accessor, take time O(log n). In contrast to an ordinary priority queue, an interval heap offers both minimum and maximum operations with the same efficiency.
The API is simple enough
> var heap = new C5.IntervalHeap<int>();
> heap.Add(10);
> heap.Add(5);
> heap.FindMin();

I found solution in this post: https://stackoverflow.com/questions/11883378/class-memcache-not-found-php#=
I found the working dll files for PHP 5.4.4
I don't knowhow stable they are but they work for sure. Credits goes to this link.

Please note that it is not 2.2.6 but works. I also mirrored them in my own FTP. Mirror links:

SUBSTR
will be better than FLOOR
in some cases because FLOOR has a "bug" as follow:
SELECT 25 * 9.54 + 0.5 -> 239.00
SELECT FLOOR(25 * 9.54 + 0.5) -> 238 (oops!)
SELECT SUBSTR((25*9.54+0.5),1,LOCATE('.',(25*9.54+0.5)) - 1) -> 239
I had the same problem.
Solved by sharing internet connection (on the hosting OS).
Network Connection Properties -> advanced -> Allow other users to connect...
mysql -s -N -username -p information_schema -e 'SELECT Variable_Value FROM GLOBAL_VARIABLES WHERE Variable_Name = "datadir"'
The command will select the value only from MySQL's internal information_schema database and disables the tabular output and column headers.
Output on Linux [mine result]:
/var/lib/mysql
or

on MYSQL CLI
and then
cd /var/lib/mysql && rm -rf test/NOTEMPTY

One can also use RLIKE

I would do this:
// add appropriate media query if required to target mobile nav only
.nav { overflow-y: hidden !important }
This should make sure the nav block doesn't stretch downpage and covers the page content.
do not make headaches for yourself, want a simple, one line solution to add a permanent environment variable (open powershell in elevated mode):
[Environment]::SetEnvironmentVariable("NewEnvVar", "NewEnvValue", "Machine")
close the session and open it again to make things done
in case that u want to modify/change that:
[Environment]::SetEnvironmentVariable("oldEnvVar", "NewEnvValue", "Machine")
in case that u want to delete/remove that:
[Environment]::SetEnvironmentVariable("oldEnvVar", "", "Machine")
OK, just ran into this. Buttons in Lollipop come out all uppercase AND the font resets to 'normal'. But in my case (Android 5.02) it was working in one layout correctly, but not another!?
Changing APIs didn't work.
Setting to all caps requires min API 14 and the font still resets to 'normal'.
It's because the Android Material Styles forces a change to the styles if there isn't one defined (that's why it worked in one of my layout and not the other because I defined a style).
So the easy fix is to define a style in the manifest for each activity which in my case was just:
android:theme="@android:style/Theme.NoTitleBar.Fullscreen"
(hope this helps someone, would have saved me a couple of hours last night)
USE style="max-width:90%;"
<select name=countries style="max-width:90%;">
<option value=af>Afghanistan</option>
<option value=ax>Åland Islands</option>
...
<option value=gs>South Georgia and the South Sandwich Islands</option>
...
</select>
Doing alist = []
does not clear the list, just creates an empty list and binds it to the variable alist
. The old list will still exist if it had other variable bindings.
To actually clear a list in-place, you can use any of these ways:
alist.clear() # Python 3.3+, most obvious
del alist[:]
alist[:] = []
alist *= 0 # fastest
See the Mutable Sequence Types documentation page for more details.
I was able to use Joey's Answer to create a function:
Use it as:
@echo off
SETLOCAL ENABLEDELAYEDEXPANSION
SET "MYTEXT=jump over the chair"
echo !MYTEXT!
call:ReplaceText "!MYTEXT!" chair table RESULT
echo !RESULT!
GOTO:EOF
And these Functions to the bottom of your Batch File.
:FUNCTIONS
@REM FUNCTIONS AREA
GOTO:EOF
EXIT /B
:ReplaceText
::Replace Text In String
::USE:

::Example
::SET "MYTEXT=jump over the chair"
:: echo !MYTEXT!
:: call:ReplaceText "!MYTEXT!" chair table RESULT
:: echo !RESULT!
::
:: Remember to use the "! on the input text, but NOT on the Output text.
:: The Following is Wrong: "!MYTEXT!" !chair! !table! !RESULT!
:: ^^Because it has a ! around the chair table and RESULT
:: Remember to add quotes "" around the MYTEXT Variable when calling.
:: If you don't add quotes, it won't treat it as a single string

set "OrginalText=%~1"
set "OldWord=%~2"
set "NewWord=%~3"
call set OrginalText=%%OrginalText:!OldWord!=!NewWord!%%

And remember you MUST add "SETLOCAL ENABLEDELAYEDEXPANSION" to the top of your batch file or else none of this will work properly.

Calling document.write()
on a page that is not open (e.g. has finished loading) first calls document.open()
which clears the entire content of the document (including the script calling document.write), so it's rarely a good idea to do that.
You can use map
:
List<String> names =
personList.stream()
.map(Person::getName)
.collect(Collectors.toList());
EDIT :
In order to combine the Lists of friend names, you need to use flatMap
:
List<String> friendNames =
personList.stream()
.flatMap(e->e.getFriends().stream())
.collect(Collectors.toList());
Below code avoids creating infinite loop. Assume XYZ is the string which we are looking for in the workbook.

Set Loc = .Cells.Find(What:="XYZ")
If Not Loc Is Nothing Then
MsgBox ("Value is found in " & Sh.Name)
myCounter = 1
Set Loc = .FindNext(Loc)
End If
End With
Next
If myCounter = 0 Then
MsgBox ("Value not present in this worrkbook")
End If
End Sub
For me, this started happening on a project that was working, but then one day I got this error. I tried all suggestions around the .vs folder, applicationhost.config file, changing ports, restarting VS, rebooting Windows, reinstalling IIS Express. Nothing worked. I even created a new bare-bones web app, and got the same error. I have a feeling the IT department made some kind of change to my system.
After I try to run the project and IIS Express has started, in my elevated cmd prompt I run netstat -ano |find "44312"
where 44312 is the port number of my web application. I noticed what's returned is not the usual localhost IP (127.0.0.1). It was some external IP. It tells me IIS Express using a different IP.
Then I ran netsh http show iplisten
and I see that same IP in the results. netsh http delete iplisten [external ip]
, and BOOM! the web app loads!
I'm doing something similar, but in my case I'm doing serialization/De-serialization so I need to be able to go both directions. I find using a string[][] works nearly identically to the dictionary, including initialization, but you can go the other direction too, returning the substitutes to their original values, something that the dictionary really isn't set up to do.
Edit: You can use Dictionary<Key,List<Values>>
in order to obtain same result as string[][]
You are first setting opacity: 1;
and then you are ending it on 0
, so it starts from 0%
and ends on 100%
, so instead just set opacity to 0
at 50%
and the rest will take care of itself.

Here, I am setting the animation duration to be 1 second
, and then I am setting the timing
to linear
. That means it will be constant throughout. Last, I am using infinite
. That means it will go on and on.
Note: If this doesn't work for you, use browser prefixes like
-webkit
,-moz
and so on as required foranimation
and@keyframes
. You can refer to my detailed code here
As commented, this won't work on older versions of Internet Explorer, and for that you need to use jQuery or JavaScript...
(function blink() {
$('.blink_me').fadeOut(500).fadeIn(500, blink);
})();
Thanks to Alnitak for suggesting a better approach.

As hanry has mentioned above putting liner iterpolator is fine. But if rotation is inside a set you must put android:shareInterpolator="false" to make it smooth.
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
**android:shareInterpolator="false"**
>
<rotate
android:interpolator="@android:anim/linear_interpolator"
android:duration="300"
android:fillAfter="true"
android:repeatCount="10"
android:repeatMode="restart"
android:fromDegrees="0"
android:toDegrees="360"
android:pivotX="50%"
android:pivotY="50%" />
<scale xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="@android:anim/linear_interpolator"
android:duration="3000"
android:fillAfter="true"
android:pivotX="50%"
android:pivotY="50%"
android:fromXScale="1.0"
android:fromYScale="1.0"
android:toXScale="0"
android:toYScale="0" />
</set>
If Sharedinterpolator being not false, the above code gives glitches.
You may try the following if your database does not have any data OR you have another away to restore that data. You will need to know the Ubuntu server root password but not the mysql root password.
It is highly probably that many of us have installed "mysql_secure_installation" as this is a best practice. Navigate to bin directory where mysql_secure_installation exist. It can be found in the /bin directory on Ubuntu systems. By rerunning the installer, you will be prompted about whether to change root database password.
Download Androidx86 from this This is an iso file, so you'd
need something like VMWare or VirtualBox to run it When creating the virtual machine, you need to set the type of guest OS as Linux
instead of Other.
After creating the virtual machine set the network adapter to 'Bridged'. · Start the VM and select 'Live CD VESA' at boot.
Now you need to find out the IP of this VM. Go to terminal in VM (use Alt+F1 & Alt+F7 to toggle) and use the netcfg command to find this.
Now you need open a command prompt and go to your android install folder (on host). This is usually C:\Program Files\Android\android-sdk\platform-tools>.
Type adb connect IP_ADDRESS. There done! Now you need to add Bluetooth. Plug in your USB Bluetooth dongle/Bluetooth device.
In VirtualBox screen, go to Devices>USB devices. Select your dongle.
Done! now your Android VM has Bluetooth. Try powering on Bluetooth and discovering/paring with other devices.
Now all that remains is to go to Eclipse and run your program. The Android AVD manager should show the VM as a device on the list.
Alternatively, Under settings of the virtual machine, Goto serialports -> Port 1 check Enable serial port select a port number then select port mode as disconnected click ok. now, start virtual machine. Under Devices -> USB Devices -> you can find your laptop bluetooth listed. You can simply check the option and start testing the android bluetooth application .
After much pain, and great assistance from @vitr et al above, i decided to try
and that worked.
ENV LISTEN_PORT=""
ENTRYPOINT java -cp "app:app/lib/*" hello.Application --server.port=${LISTEN_PORT:-80}
e.g.
docker run --rm -p 8080:8080 -d --env LISTEN_PORT=8080 my-image
and
docker run --rm -p 8080:80 -d my-image
both set the port correctly in my container

Most build systems use data time stamps to determine when rebuilds should happen - the date/time stamp of any output files is checked against the last modified time of the dependencies - if any of the dependencies are fresher, then the target is rebuilt.
This can cause problems if any of the dependencies somehow get an invalid data time stamp as it's difficult for the time stamp of any build output to ever exceed the timestamp of a file supposedly created in the future :P
json_decode will return the same array that was originally encoded. For instanse, if you
$array = json_decode($json, true);
echo $array['countryId'];
OR
$obj= json_decode($json);
echo $obj->countryId;
These both will echo 84. I think json_encode and json_decode function names are self-explanatory...
For me the problem was my file encoding...I used powershell to write the xml file and this was not UTF-8 ... It seems that spring requires UTF8 because as soon as I changed the encoding (using notepad++) it works again without any errors
Now i Use in my powershellscript the following line to output the xml file in UTF-8: [IO.File]::WriteAllLines($fname_dataloader_xml_config_file, $dataloader_configfile)
instead of using the redirection operator > to create my file
Note: I didn't put any xml parameters in my beans tag and it works
Update: This answer is no longer available as Whatsapp had stopped exposing the phone number as account name, kindly disregard this answer.
=================================================================================
Its been almost 6 months and I believe I should update this with an alternative solution you might want to consider.
As of today, you can rely on another big application Whatsapp, using AccountManager. Millions of devices have this application installed and if you can't get the phone number via TelephonyManager, you may give this a shot.
Permission:
<uses-permission android:name="android.permission.GET_ACCOUNTS" />
Code:
AccountManager am = AccountManager.get(this);
Account[] accounts = am.getAccounts();
ArrayList<String> googleAccounts = new ArrayList<String>();
for (Account ac : accounts) {
String acname = ac.name;
String actype = ac.type;
// Take your time to look at all available accounts
System.out.println("Accounts : " + acname + ", " + actype);
}
Check actype for whatsapp account
if(actype.equals("com.whatsapp")){
String phoneNumber = ac.name;
}
Of course you may not get it if user did not install Whatsapp, but its worth to try anyway. And remember you should always ask user for confirmation.
Here's a simple class I cobbled together from various posts.... It's been tested for about 15 minutes, but seems to work for my purposes. It uses JavascriptSerializer
to do the work, which can be referenced in your app using the info detailed in this post.
The below code can be run in LinqPad to test it out by:

You should be able to create a query with this filter here:
(&(objectClass=user)(sAMAccountName=yourUserName)
(memberof=CN=YourGroup,OU=Users,DC=YourDomain,DC=com))
and when you run that against your LDAP server, if you get a result, your user "yourUserName" is indeed a member of the group "CN=YourGroup,OU=Users,DC=YourDomain,DC=com
Try and see if this works!
If you use C# / VB.Net and System.DirectoryServices, this snippet should do the trick:
DirectoryEntry rootEntry = new DirectoryEntry("LDAP://dc=yourcompany,dc=com");
DirectorySearcher srch = new DirectorySearcher(rootEntry);
srch.SearchScope = SearchScope.Subtree;
srch.Filter = "(&(objectClass=user)(sAMAccountName=yourusername)(memberOf=CN=yourgroup,OU=yourOU,DC=yourcompany,DC=com))";
SearchResultCollection res = srch.FindAll();
if(res == null || res.Count <= 0) {
Console.WriteLine("This user is *NOT* member of that group");
} else {
Console.WriteLine("This user is INDEED a member of that group");
}
Word of caution: this will only test for immediate group memberships, and it will not test for membership in what is called the "primary group" (usually "cn=Users") in your domain. It does not handle nested memberships, e.g. User A is member of Group A which is member of Group B - that fact that User A is really a member of Group B as well doesn't get reflected here.

It was windows permission issue i move the folder thats it inherit wrong permissions. When i move to wwwroot folder and add permission to iis user it start working fine.
Getting the ball rolling with this community wiki answer. Feel free to edit me with your improvements.
ws WebSocket server and client for node.js. One of the fastest libraries if not the fastest one.
websocket-node WebSocket server and client for node.js
websocket-driver-node WebSocket server and client protocol parser node.js - used in faye-websocket-node
faye-websocket-node WebSocket server and client for node.js - used in faye and sockjs
socket.io WebSocket server and client for node.js + client for browsers + (v0 has newest to oldest fallbacks, v1 of Socket.io uses engine.io) + channels - used in stack.io. Client library tries to reconnect upon disconnection.
sockjs WebSocket server and client for node.js and others + client for browsers + newest to oldest fallbacks
faye WebSocket server and client for node.js and others + client for browsers + fallbacks + support for other server-side languages
deepstream.io clusterable realtime server that handles WebSockets & TCP connections and provides data-sync, pub/sub and request/response
socketcluster WebSocket server cluster which makes use of all CPU cores on your machine. For example, if you were to use an xlarge Amazon EC2 instance with 32 cores, you would be able to handle almost 32 times the traffic on a single instance.
primus Provides a common API for most of the libraries above for easy switching + stability improvements for all of them.
When to use:
use the basic WebSocket servers when you want to use the native WebSocket implementations on the clientside, beware of the browser incompatabilities
use the fallback libraries when you care about browser fallbacks
use the full featured libraries when you care about channels
use primus when you have no idea about what to use, are not in the mood for rewriting your application when you need to switch frameworks because of changing project requirements or need additional connection stability.
Where to test:
Firecamp is a GUI testing environment for SocketIO, WS and all major real-time technology. Debug the real-time events while you're developing it.

Way to get Excel data to text file in tab delimited form. Need to use Pandas as well as xlrd.
import pandas as pd
import xlrd
import os
Path="C:\downloads"
wb = pd.ExcelFile(Path+"\\input.xlsx", engine=None)
sheet2 = pd.read_excel(wb, sheet_name="Sheet1")
Excel_Filter=sheet2[sheet2['Name']=='Test']
Excel_Filter.to_excel("C:\downloads\\output.xlsx", index=None)
wb2=xlrd.open_workbook(Path+"\\output.xlsx")
df=wb2.sheet_by_name("Sheet1")
x=df.nrows
y=df.ncols
for i in range(0,x):
for j in range(0,y):
A=str(df.cell_value(i,j))
f=open(Path+"\\emails.txt", "a")
f.write(A+"\t")
f.close()
f=open(Path+"\\emails.txt", "a")
f.write("\n")
f.close()
os.remove(Path+"\\output.xlsx")
print(Excel_Filter)
We need to first generate the xlsx file with filtered data and then convert the information into a text file.
Depending on requirements, we can use \n \t for loops and type of data we want in the text file.
I had the same problem with the Macports port "openocd" (locally modified the Portfile to use the git repository) on a freshly installed machine.
The permanent fix is easy, define a dependency to pkgconfig in the Portfile: depends_lib-append port:pkgconfig
And if you're building a Windows app, use the GetFileSizeEx API as CRT file I/O is messy, especially for determining file length, due to peculiarities in file representations on different systems ;)

Updating ReportViewer should works. Use below instruction to install updated ReportViewer from Nuget Package Manager console.
Install-Package Microsoft.ReportingServices.ReportViewerControl.WebForms
Just add below assembly reference in your aspx file.
Here, 15.0.0.0 is the version number of the ReportViewerControl.WebForms that was installed in my VS. Please check Reference of the Solution to confirm the version number. No need to add PublicTokens (if multiple installation exists, it may creates trouble again).
There is another, newer and quicker way to do this from within Visual Studio. Check out this post by David Ebbo, and reference the comments section if you run into trouble. Basically, you do the following in Package Manager prompt:
PM> Install-Package NuGetPowerTools
PM> Enable-PackageRestore
Afterwards, when you build your solution the packages will be automatically installed if they're missing.
Update:
This functionality is built into Nuget 1.6 with visual studio integration so you don't even need to install NuGetPowerTools or type commands. All you have to do is
Right click on the Solution node in Solution Explorer and select Enable NuGet Package Restore.
Read this article for more details.
You can simply use .toString()
.
var result = require('child_process').execSync('rsync -avAXz --info=progress2 "/src" "/dest"').toString();
console.log(result);
This has been tested on Node v8.5.0
, I'm not sure about previous versions. According to @etov, it doesn't work on v6.3.1
- I'm not sure about in-between.
Edit: Looking back on this, I've realised that it doesn't actually answer the specific question because it doesn't show the output to you 'live' — only once the command has finished running.
However, I'm leaving this answer here because I know quite a few people come across this question just looking for how to print the result of the command after execution.
For swift 2.0 and above do this
@IBOutlet weak var imageView: UIImageView!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
let tap = UITapGestureRecognizer(target: self, action: #selector(ViewController.tappedMe))
imageView.addGestureRecognizer(tap)
imageView.userInteractionEnabled = true
}
func tappedMe()
{
print("Tapped on Image")
}
If you just need to detect a palindrome, you can do it with a regex, as explained here. Probably not the most efficient approach, though...
If you have a unique column in your table (e.g. tableid) then try this.
SELECT EMAIL FROM TABLE WHERE TABLEID IN
(SELECT MAX(TABLEID), EMAIL FROM TABLE GROUP BY EMAIL)
The files are located in your node_modules/react-scripts

Now, the purpose of CRA is not to worry about these.
From the documentation:
You don’t need to install or configure tools like Webpack or Babel. They are preconfigured and hidden so that you can focus on the code.
If you want to have access to the config files, you need to eject by running:
npm run eject
Note: this is a one-way operation. Once you eject, you can’t go back!
In most scenarios, it is best not to eject and try to find a way to make it work for you in another way.
If you need to override some of the config options, you can have a look at https://github.com/gsoft-inc/craco
Figured this out. Pretty simple:
new PDO("sqlsrv:server=[sqlservername];Database=[sqlserverdbname]", "[username]", "[password]");
content
doesn't support HTML, only text. You should probably use javascript, jQuery or something like that.
Another problem with your code is "
inside a "
block. You should mix '
and "
(class='headingDetail'
).
If content
did support HTML you could end up in an infinite loop where content
is added inside content
.
Library makefiles, which are generated by autotools (the ./configure
you have to issue) often have a verbose option, so basically, using make VERBOSE=1
or make V=1
should give you the full commands.
But this depends on how the makefile was generated.
The -d
option might help, but it will give you an extremely long output.
var newTH = document.createElement('th');
newTH.setAttribute("onclick", "removeColumn(#)");
newTH.setAttribute("id", "#");
function removeColumn(#){
// remove column #
}
I had the same error today, after deploying our service calling an external service to the staging environment in azure. Local the service called the external service without errors, but after deployment it didn't.
In the end it turned out to be that the external service has a IP validation. The new environment in Azure has another IP and it was rejected.
So if you ever get this error calling external services
It might be an IP restriction.
print_r($this->session->userdata);
or
print_r($this->session->all_userdata());
you also can try to use that:
table {
table-layout:fixed;
}
table td {
width: 30px;
overflow: hidden;
text-overflow: ellipsis;
}
While using the wait
and notify
or notifyAll
methods in Java the following things must be remembered:
notifyAll
instead of notify
if you expect that more than one thread will be waiting for a lock. wait
and notify
methods must be called in a synchronized context. See the link for a more detailed explanation. wait()
method in a loop because if multiple threads are waiting for a lock and one of them got the lock and reset the condition, then the other threads need to check the condition after they wake up to see whether they need to wait again or can start processing. wait()
and notify()
method; every object has its own lock so calling wait()
on object A and notify()
on object B will not make any sense.More information will be useful.
When I was faced with the same error message all I had to do was to correctly configure the credentials page of the DataSource(I am using Report Builder 3). if you chose the default, the report would work fine in Report Builder but would fail on the Report Server.
You may review more details of this fix here: https://hodentekmsss.blogspot.com/2017/05/fix-for-rserroropeningconnection-in.html
Another option is http://localtunnel.me/ if you're running NodeJS
npm install -g localtunnel
Start a webserver on any local port such as 8080, and create a tunnel to that port:
lt -p 8080
which will return a public URL for your localhost at randomname.localtunnel.me. You can request your own subdomain if it's available:
lt -p 8080 -s myname
which will return myname.localtunnel.me
PLEASE don't go loading another library just to do something that's already natively available!
jQuery's .css()
converts %'s and em's to their pixel equivalent to begin with, and parseInt()
will remove the 'px'
from the end of the returned string and convert it to an integer:
$(document).ready(function () {
var $h1 = $('h1');
console.log($h1);
$h1.after($('<div>Padding-top: ' + parseInt($h1.css('padding-top')) + '</div>'));
$h1.after($('<div>Margin-top: ' + parseInt($h1.css('margin-top')) + '</div>'));
});
OutputStream is an abstract class that represents writing output. There are many different OutputStream classes, and they write out to certain things (like the screen, or Files, or byte arrays, or network connections, or etc). InputStream classes access the same things, but they read data in from them.
Here is a good basic example of using FileOutputStream and FileInputStream to write data to a file, then read it back in.
There's an overload of String.Split for this:
"THExxQUICKxxBROWNxxFOX".Split(new [] {"xx"}, StringSplitOptions.None);
Maybe late to the party but in my case it was RHEL 6.8:

The reason to prefer Promises over callback functions is to have multiple callbacks and to avoid the problems like Callback Hell.
Callback hell (for more details, refer http://callbackhell.com/): Asynchronous javascript, or javascript that uses callbacks, is hard to get right intuitively. A lot of code ends up looking like this:
asyncCall(function(err, data1){
if(err) return callback(err);
anotherAsyncCall(function(err2, data2){
if(err2) return calllback(err2);
oneMoreAsyncCall(function(err3, data3){
if(err3) return callback(err3);
// are we done yet?
});
});
});
With Promises above code can be rewritten as below:
asyncCall()
.then(function(data1){
// do something...
return anotherAsyncCall();
})
.then(function(data2){
// do something...
return oneMoreAsyncCall();
})
.then(function(data3){

})
.fail(function(err) {
// handle any error resulting from any of the above calls
})
.done();
You should really use for()
instead of foreach()
in this case.
In general custom audit (creating various tables) is a bad option. Database/table triggers can be disabled to skip some log activities. Custom audit tables can be tampered. Exceptions can take place that will bring down application. Not to mentions difficulties designing a robust solution. So far I see a very simple cases in this discussion. You need a complete separation from current database and from any privileged users(DBA, Developers). Every mainstream RDBMSs provide audit facilities that even DBA not able to disable, tamper in secrecy. Therefore, provided audit capability by RDBMS vendor must be the first option. Other option would be 3rd party transaction log reader or custom log reader that pushes decomposed information into messaging system that ends up in some forms of Audit Data Warehouse or real time event handler. In summary: Solution Architect/"Hands on Data Architect" needs to involve in destining such a system based on requirements. It is usually too serious stuff just to hand over to a developers for solution.
I think that you should make the reference to your config file
26399:C 16 Jan 08:51:13.413 # Warning: no config file specified, using the default config. In order to specify a config file use ./redis-server /path/to/redis.conf
you can try to start your redis server like
./redis-server /path/to/redis-stable/redis.conf
I ended up finding git attributes
. Trying it. Working so far. Did not check all scenarios yet. But it should be the solution.
Somthing like this should workL
SELECT BookingId, StartTime
FROM Booking
WHERE StartTime between dateadd(hour, -1, getdate()) and getdate()
For those using RestSharp, it might fail when using SimpleAuthenticator (possibly due to not using ISO-8859-1 behind the scene). I managed to get it done by explicitly sending Basic Authentication headers:
string username = "...";
string password = "...";
public IRestResponse GetResponse(string url, Method method = Method.GET)
{
string encoded = Convert.ToBase64String(Encoding.GetEncoding("ISO-8859-1").GetBytes($"{username}:{password}"));
var client = new RestClient(url);
var request = new RestRequest(method );
request.AddHeader("Authorization", $"Basic {encoded}");
IRestResponse response = client.Execute(request);
return response;
}
var response = GetResponse(url);
txtResult.Text = response.Content;
String original = "hello world";
byte[] utf8Bytes = original.getBytes("UTF-8");
Use the RAISERROR
function:
RAISERROR( 'This message will show up right away...',0,1) WITH NOWAIT
You shouldn't completely replace all your prints with raiserror. If you have a loop or large cursor somewhere just do it once or twice per iteration or even just every several iterations.
Also: I first learned about RAISERROR at this link, which I now consider the definitive source on SQL Server Error handling and definitely worth a read:
http://www.sommarskog.se/error-handling-I.html
You need to specify the minimum width of the field.
String.format("%" + numberOfSpaces + "s", "");
Why do you want to generate a String of spaces of a certain length.
If you want a column of this length with values then you can do:
String.format("%" + numberOfSpaces + "s", "Hello");
which gives you numberOfSpaces-5 spaces followed by Hello. If you want Hello to appear on the left then add a minus sign in before numberOfSpaces.
You can do this:
if ($(".parent a[Id]").length > 0) {
/* then do something here */
}
here's how:
import pygame
screen=pygame.display.set_mode([640, 480])
screen.fill([255, 255, 255])
red=255
blue=0
green=0
left=50
top=50
width=90
height=90
filled=0
pygame.draw.rect(screen, [red, blue, green], [left, top, width, height], filled)
pygame.display.flip()
running=True
while running:
for event in pygame.event.get():
if event.type==pygame.QUIT:
running=False
pygame.quit()
I had to put the statement under the [mysqld] block to make it work. Otherwise the change was not reflected. I have a REL distribution.
H2CO3 is right, you can use a makefile with the CXXFLAGS set with -std=c++11 A makefile is a simple text file with instructions about how to compile your program. Create a new file named Makefile (with a capital M). To automatically compile your code just type the make command in a terminal. You may have to install make.
Here's a simple one :
CXX=clang++
CXXFLAGS=-g -std=c++11 -Wall -pedantic
BIN=prog
SRC=$(wildcard *.cpp)
OBJ=$(SRC:%.cpp=%.o)
all: $(OBJ)
$(CXX) -o $(BIN) $^
%.o: %.c
$(CXX) $@ -c $<
clean:
rm -f *.o
rm $(BIN)
It assumes that all the .cpp files are in the same directory as the makefile. But you can easily tweak your makefile to support a src, include and build directories.
Edit : I modified the default c++ compiler, my version of g++ isn't up-to-date. With clang++ this makefile works fine.
Expanding on the answer by @gordon, here's an example of readable syntax and argument passing with shell/command module (these differ from the git module in that there are required but free-form arguments, as noted by @ander)
- name: "release tarball is generated" local_action: module: shell _raw_params: git archive --format zip --output release.zip HEAD chdir: "files/clones/webhooks"
I might have a solution for the video as background, stretched to the browser-width or height, (but the video will still preserve the aspect ratio, couldnt find a solution for that yet.):
Put the video right after the body-tag with style="width:100%;"
.
Right afterwords, put a "bodydummy"-tag:
<body>
<video id="bgVideo" autoplay poster="videos/poster.png">
<source src="videos/test-h264-640x368-highqual-winff.mp4" type="video/mp4"/>
<source src="videos/test-640x368-webmvp8-miro.webm" type="video/webm"/>
<source src="videos/test-640x368-theora-miro.ogv" type="video/ogg"/>
</video>
<img id="bgImg" src="videos/poster.png" />
<!-- This image stretches exactly to the browser width/height and lies behind the video-->
<div id="bodyDummy">
Put all your content inside the bodydummy
-div and put the z-indexes correctly in CSS like this:
#bgImg{
position: absolute;
top: 0;
left: 0;
border: 0;
z-index: 1;
width: 100%;
height: 100%;
}
#bgVideo{
position: absolute;
top: 0;
left: 0;
border: 0;
z-index: 2;
width: 100%;
height: 100%;
}
#bodyDummy{
position: absolute;
top: 0;
left: 0;
z-index: 3;
overflow: auto;
width: 100%;
height: 100%;
}
Hope I could help. Let me know when you could find a solution that the video does not maintain the aspect ratio, so it could fill the whole browser window so we do not have to put a bgimage.
You should use container-fluid
, not container
. See example: http://www.bootply.com/onAFpJcslS
This task can be accomplished using one of the android's main building block named as Intents and One of the methods public void startActivity (Intent intent)
which belongs to your Activity class.
An intent is an abstract description of an operation to be performed. It can be used with startActivity to launch an Activity, broadcastIntent to send it to any interested BroadcastReceiver components, and startService(Intent) or bindService(Intent, ServiceConnection, int) to communicate with a background Service.
An Intent provides a facility for performing late runtime binding between the code in different applications. Its most significant use is in the launching of activities, where it can be thought of as the glue between activities. It is basically a passive data structure holding an abstract description of an action to be performed.
Refer the official docs -- http://developer.android.com/reference/android/content/Intent.html
public void startActivity (Intent intent)
-- Used to launch a new activity.
So suppose you have two Activity class --
PresentActivity -- This is your current activity from which you want to go the second activity.
NextActivity -- This is your next Activity on which you want to move.
So the Intent would be like this
Intent(PresentActivity.this, NextActivity.class)
Finally this will be the complete code
public class PresentActivity extends Activity {
protected void onCreate(Bundle icicle) {
super.onCreate(icicle);
setContentView(R.layout.content_layout_id);
final Button button = (Button) findViewById(R.id.button_id);
button.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// Perform action on click
Intent activityChangeIntent = new Intent(PresentActivity.this, NextActivity.class);
// currentContext.startActivity(activityChangeIntent);
PresentActivity.this.startActivity(activityChangeIntent);
}
});
}
}
I came across this as well, for me this has worked (covers most browsers):
myString.replace(/[\s\uFEFF\xA0]/g, ';');

I don't know anymore where I get the part of this enum extension, but it is from stackoverflow. I am sorry for this! But I took this one and modified it for enums with Flags. For enums with Flags I did this:
public static class Enum<T> where T : struct
{
private static readonly IEnumerable<T> All = Enum.GetValues(typeof (T)).Cast<T>();
private static readonly Dictionary<int, T> Values = All.ToDictionary(k => Convert.ToInt32(k));
public static T? CastOrNull(int value)
{
T foundValue;
if (Values.TryGetValue(value, out foundValue))
{
return foundValue;
}
// For enums with Flags-Attribut.
try
{
bool isFlag = typeof(T).GetCustomAttributes(typeof(FlagsAttribute), false).Length > 0;
if (isFlag)
{
int existingIntValue = 0;
foreach (T t in Enum.GetValues(typeof(T)))
{
if ((value & Convert.ToInt32(t)) > 0)
{
existingIntValue |= Convert.ToInt32(t);
}
}
if (existingIntValue == 0)
{
return null;
}
return (T)(Enum.Parse(typeof(T), existingIntValue.ToString(), true));
}
}
catch (Exception)
{
return null;
}
return null;
}
}
Example:
[Flags]
public enum PetType
{
None = 0, Dog = 1, Cat = 2, Fish = 4, Bird = 8, Reptile = 16, Other = 32
};
integer values
1=Dog;
13= Dog | Fish | Bird;
96= Other;
128= Null;
You could do something using the grep command:
find . | grep -v '(dll|exe)$'
The -v
flag on grep
specifically means "find things that don't match this expression."
Range("A10") = WorksheetFunction.Sum(Worksheets("Sheet1").Range("A1", "A9"))
Where
Range("A10")
is the answer cell
Range("A1", "A9")
is the range to calculate
It's best practice to use COPY
instead of ADD
when you're copying from the local file system to the image. Also, I'd recommend creating a sub-folder to place your content into. If nothing else, it keeps things tidy. Make sure you mark the script as executable using chmod
.
Here, I am creating a scripts
sub-folder to place my script into and run it from:
RUN mkdir -p /scripts
COPY script.sh /scripts
WORKDIR /scripts
RUN chmod +x script.sh
RUN script.sh
The one-liner I use in Windows Server 2008 R2 is:
cmd /v:on /c "echo !TIME! & *mycommand* & echo !TIME!"
So long as mycommand doesn't require quotes (which screws with cmd's quote processing). The /v:on
is to allow for the two different TIME values to be evaluated independently rather than once at the execution of the command.
Just in case it helps someone - In my scenario, I have some shared libraries (Which have their own TFS projects/solutions) all combined into one solution.
Nuget would restore projects successfully, but the DLL would be missing.
The underlying issue was that, whilst your solution has its own packages folder and has restored them correctly to that folder, the project file (e.g. .csproj) is referencing a different project which may not have the package downloaded. Open the file in a text editor to see where your references are coming from.
This can occur when managing packages on different interlinked shared solutions - since you probably want to make sure all DLLs are on the same level you might set this at the top level. This means it that sometimes it will be looking in a completely different solution for a referenced DLL and so if you don't have all projects/solutions downloaded and up-to-date then you may get the above problem.
Today, I was testing this with iOS 9 Beta and found the solution.
To solve it, go to:
Simply, static functions function independently of the class where they belong.
$this means, this is an object of this class. It does not apply to static functions.
class test {
public function sayHi($hi = "Hi") {
$this->hi = $hi;
return $this->hi;
}
}
class test1 {
public static function sayHi($hi) {
$hi = "Hi";
return $hi;
}
}
// Test
$mytest = new test();
print $mytest->sayHi('hello'); // returns 'hello'
print test1::sayHi('hello'); // returns 'Hi'
SELECT *
FROM table_name
WHERE table_name.the_date > DATE_SUB(CURDATE(), INTERVAL 1 DAY)
There is a RawFormat property of Image parameter which returns the file format of the image. You might try the following:
// extension method
public static byte[] imageToByteArray(this System.Drawing.Image image)
{
using(var ms = new MemoryStream())
{
image.Save(ms, image.RawFormat);
return ms.ToArray();
}
}
Don't wanna use "position:absolute" for sticky footer at bottom. Then you can do this way:
html,_x000D_
body {_x000D_
height: 100%;_x000D_
margin: 0;_x000D_
}_x000D_
.wrapper {_x000D_
min-height: 100%;_x000D_
/* Equal to height of footer */_x000D_
/* But also accounting for potential margin-bottom of last child */_x000D_
margin-bottom: -50px;_x000D_
}_x000D_
.footer{_x000D_
background: #000;_x000D_
text-align: center;_x000D_
color: #fff;_x000D_
}_x000D_
.footer,_x000D_
.push {_x000D_
height: 50px;_x000D_
}
_x000D_
<html>_x000D_
<body>_x000D_
<!--HTML Code-->_x000D_
<div class="wrapper">_x000D_
<div class="content">content</div>_x000D_
<div class="push"></div>_x000D_
</div>_x000D_
<footer class="footer">test</footer>_x000D_
</body>_x000D_
</html>
_x000D_
You probably want something like this:
Collections.sort(students, new Comparator<Student>() {
public int compare(Student s1, Student s2) {
if(s1.getName() != null && s2.getName() != null && s1.getName().comareTo(s1.getName()) != 0) {
return s1.getName().compareTo(s2.getName());
} else {
return s1.getAge().compareTo(s2.getAge());
}
}
);
This sorts the students first by name. If a name is missing, or two students have the same name, they are sorted by their age.
$customer_id = get_current_user_id();
print get_user_meta( $customer_id, 'billing_first_name', true );
You can just "call" your model with an array of the correct shape:
model(np.array([[6.7, 3.3, 5.7, 2.5]]))
Full example:
from sklearn.datasets import load_iris
from tensorflow.keras.layers import Dense
from tensorflow.keras.models import Sequential
import numpy as np
X, y = load_iris(return_X_y=True)
model = Sequential([
Dense(16, activation='relu'),
Dense(32, activation='relu'),
Dense(1)])
model.compile(loss='mean_absolute_error', optimizer='adam')
history = model.fit(X, y, epochs=10, verbose=0)
print(model(np.array([[6.7, 3.3, 5.7, 2.5]])))
<tf.Tensor: shape=(1, 1), dtype=float64, numpy=array([[1.92517677]])>
I was looking at the answers and... realized that nobody thought about FLOAT numbers (with dot)!
Using grep is great too.
-E means extended regexp
-q means quiet (doesn't echo)
-qE is the combination of both.
To test directly in the command line:
$ echo "32" | grep -E ^\-?[0-9]?\.?[0-9]+$
# answer is: 32
$ echo "3a2" | grep -E ^\-?[0-9]?\.?[0-9]+$
# answer is empty (false)
$ echo ".5" | grep -E ^\-?[0-9]?\.?[0-9]+$
# answer .5
$ echo "3.2" | grep -E ^\-?[0-9]?\.?[0-9]+$
# answer is 3.2
Using in a bash script:
check=`echo "$1" | grep -E ^\-?[0-9]*\.?[0-9]+$`
if [ "$check" != '' ]; then
# it IS numeric
echo "Yeap!"
else
# it is NOT numeric.
echo "nooop"
fi
To match JUST integers, use this:
# change check line to:
check=`echo "$1" | grep -E ^\-?[0-9]+$`
You might be in debug mode. If this is the problem, you can simply click on the "Java" button (next to the "Debug" button) in the upper-right hand corner, or click on "Open Perspective" and then select "Java (default)" from the "Open Perspective" window.
Thankfully(?), in SQL Server 2012+, you can now use FORMAT() to achieve this:
FORMAT(@s,'#,0.0000')
[Query]:
declare @s decimal(18,10);
set @s = 1234.1234567;
select replace(convert(varchar,cast(floor(@s) as money),1),'.00',
'.'+right(cast(@s * 10000 +10000.5 as int),4))
In the first part, we use MONEY->VARCHAR to produce the commas, but FLOOR() is used to ensure the decimals go to .00
. This is easily identifiable and replaced with the 4 digits after the decimal place using a mixture of shifting (*10000
) and CAST as INT (truncation) to derive the digits.
[Results]:
| COLUMN_0 |
--------------
| 1,234.1235 |
But unless you have to deliver business reports using SQL Server Management Studio or SQLCMD, this is NEVER the correct solution, even if it can be done. Any front-end or reporting environment has proper functions to handle display formatting.
To my knowledge, there is sadly no CSS filter to colorise an element (perhaps with the use of some SVG filter magic, but I'm somewhat unfamiliar with that) and even if that wasn't the case, filters are basically only supported by webkit browsers.
With that said, you could still work around this and use a canvas
to modify your image. Basically, you can draw an image element onto a canvas and then loop through the pixels, modifying the respective RGBA values to the colour you want.
However, canvases do come with some restrictions. Most importantly, you have to make sure that the image src comes from the same domain as the page. Otherwise the browser won't allow you to read or modify the pixel data of the canvas.

lCnt = lCnt + 1
shDest.Range("A4").Offset(0, lCnt * 4).Formula = "=" & rCell.Address(False, False, , True) & "+" & rCell.Offset(0, 1).Address(False, False, , True)
Next rCell
End Sub
This loops through column A of sheet1 and creates a formula in sheet2 for every cell. To find the last cell in Sheet1, I start at the bottom (shSource.Rows.Count) and .End(xlUp) to get the last cell in the column that's not blank.
To create the elements of the formula, I use the Address property of the cell on Sheet. I'm using three of the arguments to Address. The first two are RowAbsolute and ColumnAbsolute, both set to false. I don't care about the third argument, but I set the fourth argument (External) to True so that it includes the sheet name.
I prefer to go from Source to Destination rather than the other way. But that's just a personal preference. If you want to work from the destination,
Sub Results3()
Dim i As Long, lCnt As Long
Dim sh As Worksheet
lCnt = Application.WorksheetFunction.CountA(ThisWorkbook.Sheets("Sheet1").Columns(1))
Set sh = ThisWorkbook.Sheets("Sheet2")
Const sSOURCE As String = "Sheet1!"
For i = 1 To lCnt
sh.Range("A1").Offset(0, 4 * (i - 1)).Formula = "=" & sSOURCE & "A" & i & " + " & sSOURCE & "B" & i
Next i
End Sub
This is because of padding added to satisfy alignment constraints. Data structure alignment impacts both performance and correctness of programs:
SIGBUS
).Here's an example using typical settings for an x86 processor (all used 32 and 64 bit modes):
struct X
{
short s; /* 2 bytes */
/* 2 padding bytes */
int i; /* 4 bytes */
char c; /* 1 byte */
/* 3 padding bytes */
};
struct Y
{
int i; /* 4 bytes */
char c; /* 1 byte */
/* 1 padding byte */
short s; /* 2 bytes */
};
struct Z
{
int i; /* 4 bytes */
short s; /* 2 bytes */
char c; /* 1 byte */
/* 1 padding byte */
};
const int sizeX = sizeof(struct X); /* = 12 */
const int sizeY = sizeof(struct Y); /* = 8 */
const int sizeZ = sizeof(struct Z); /* = 8 */
One can minimize the size of structures by sorting members by alignment (sorting by size suffices for that in basic types) (like structure Z
in the example above).
IMPORTANT NOTE: Both the C and C++ standards state that structure alignment is implementation-defined. Therefore each compiler may choose to align data differently, resulting in different and incompatible data layouts. For this reason, when dealing with libraries that will be used by different compilers, it is important to understand how the compilers align data. Some compilers have command-line settings and/or special #pragma
statements to change the structure alignment settings.
Your variable size
is declared as: float size;
You can't use a floating point variable as the size of an array - it needs to be an integer value.
You could cast it to convert to an integer:
float *temp = new float[(int)size];
Your other problem is likely because you're writing outside of the bounds of the array:
float *temp = new float[size];
//Getting input from the user
for (int x = 1; x <= size; x++){
cout << "Enter temperature " << x << ": ";
// cin >> temp[x];
// This should be:
cin >> temp[x - 1];
}
Arrays are zero based in C++, so this is going to write beyond the end and never write the first element in your original code.
With the new syntax of RxJS 5.5+, this becomes as the following:
// RxJS 6
import { EMPTY, empty, of } from "rxjs";
// rxjs 5.5+ (<6)
import { empty } from "rxjs/observable/empty";
import { of } from "rxjs/observable/of";
empty(); // deprecated use EMPTY
EMPTY;
of({});
Just one thing to keep in mind, EMPTY
completes the observable, so it won't trigger next
in your stream, but only completes. So if you have, for instance, tap
, they might not get trigger as you wish (see an example below).
Whereas of({})
creates an Observable
and emits next with a value of {}
and then it completes the Observable
.
E.g.:
EMPTY.pipe(
tap(() => console.warn("i will not reach here, as i am complete"))
).subscribe();
of({}).pipe(
tap(() => console.warn("i will reach here and complete"))
).subscribe();

Another option is winsw: https://github.com/kohsuke/winsw/
Configure an xml file to specify the service name, what to execute, any arguments etc. And use the exe to install. Example xml: https://github.com/kohsuke/winsw/tree/master/examples
I prefer this to nssm, because it is one lightweight exe; and the config xml is easy to share/commit to source code.
PS the service is installed by running your-service.exe install
But that doesn't seem like the proper way to do it..
That is indeed the proper way to do it (or at least a proper way to do it). This is a key aspect of promises, they're a pipeline, and the data can be massaged by the various handlers in the pipeline.
Example:
const promises = [_x000D_
new Promise(resolve => setTimeout(resolve, 0, 1)),_x000D_
new Promise(resolve => setTimeout(resolve, 0, 2))_x000D_
];_x000D_
Promise.all(promises)_x000D_
.then(data => {_x000D_
console.log("First handler", data);_x000D_
return data.map(entry => entry * 10);_x000D_
})_x000D_
.then(data => {_x000D_
console.log("Second handler", data);_x000D_
});
_x000D_
(catch
handler omitted for brevity. In production code, always either propagate the promise, or handle rejection.)
The output we see from that is:
First handler [1,2] Second handler [10,20]
...because the first handler gets the resolution of the two promises (1
and 2
) as an array, and then creates a new array with each of those multiplied by 10 and returns it. The second handler gets what the first handler returned.
If the additional work you're doing is synchronous, you can also put it in the first handler:
Example:
const promises = [_x000D_
new Promise(resolve => setTimeout(resolve, 0, 1)),_x000D_
new Promise(resolve => setTimeout(resolve, 0, 2))_x000D_
];_x000D_
Promise.all(promises)_x000D_
.then(data => {_x000D_
console.log("Initial data", data);_x000D_
data = data.map(entry => entry * 10);_x000D_
console.log("Updated data", data);_x000D_
return data;_x000D_
});
_x000D_
...but if it's asynchronous you won't want to do that as it ends up getting nested, and the nesting can quickly get out of hand.

There are cases when it makes sense to make members of classes internal
. One example could be if you want to control how the classes are instantiated; let's say you provide some sort of factory for creating instances of the class. You can make the constructor internal
, so that the factory (that resides in the same assembly) can create instances of the class, but code outside of that assembly can't.
However, I can't see any point with making classes or members internal
without specific reasons, just as little as it makes sense to make them public
, or private
without specific reasons.
I know this question is old. But this might be useful for someone who is having the problem with legend. In addition to the answer given by ZaneDarken, I modified the chart.js file to show the legend in my pie chart. I changed the legendTemplate(which is declared many times for every chart type) just above these lines :
Chart.Type.extend({_x000D_
//Passing in a name registers this chart in the Chart namespace_x000D_
name: "Doughnut",_x000D_
//Providing a defaults will also register the deafults in the chart namespace_x000D_
defaults: defaultConfig,_x000D_
.......
_x000D_
My legendTemplate is changed from
legendTemplate : "_x000D_
<ul class=\ "<%=name.toLowerCase()%>-legend\">_x000D_
<% for (var i=0; i<datasets.length; i++){%>_x000D_
<li><span style=\ "background-color:<%=datasets[i].strokeColor%>\"></span>_x000D_
<%if(datasets[i].label){%>_x000D_
<%=datasets[i].label%>_x000D_
<%}%>_x000D_
</li>_x000D_
<%}%>_x000D_

No CSS required, visible class should like this: visible-md-block
not just visible-md
and the code should be like this:
<div class="containerdiv hidden-sm hidden-xs visible-md-block visible-lg-block">
<div class="row">
<div class="col-xs-4 col-sm-4 col-md-4 col-lg-4 logo">
</div>
</div>
</div>
<div class="mobile hidden-md hidden-lg ">
test
</div>
Extra css is not required at all.
If you need multiple modifications, like when using ant design, you can combine multiple functions like this:
const {
override,
removeModuleScopePlugin,
fixBabelImports,
} = require('customize-cra');
module.exports = override(
fixBabelImports('import', {
libraryName: 'antd',
libraryDirectory: 'es',
style: 'css',
}),
removeModuleScopePlugin(),
);
If you want to do it on your local machine instead of in the context of SQL server then I would use the following. It is what we use at my company.
$ServerName = "_ServerName_"
$DatabaseName = "_DatabaseName_"
$Query = "SELECT * FROM Table WHERE Column = ''"
#Timeout parameters
$QueryTimeout = 120
$ConnectionTimeout = 30
#Action of connecting to the Database and executing the query and returning results if there were any.
$conn=New-Object System.Data.SqlClient.SQLConnection
$ConnectionString = "Server={0};Database={1};Integrated Security=True;Connect Timeout={2}" -f $ServerName,$DatabaseName,$ConnectionTimeout
$conn.ConnectionString=$ConnectionString
$conn.Open()
$cmd=New-Object system.Data.SqlClient.SqlCommand($Query,$conn)
$cmd.CommandTimeout=$QueryTimeout
$ds=New-Object system.Data.DataSet
$da=New-Object system.Data.SqlClient.SqlDataAdapter($cmd)
[void]$da.fill($ds)
$conn.Close()
$ds.Tables
Just fill in the $ServerName, $DatabaseName and the $Query variables and you should be good to go.
I am not sure how we originally found this out, but there is something very similar here.
Another possible way are namespaces:
#include <iostream>
namespace mySpace {
static const int T = 100;
}
using namespace std;
class T1
{
public:
T1()
{
cout << "T1 constructor: " << mySpace::T << endl;
}
};
The disadvantage is that other classes can also use the constants if they include the header file.
Use the command:
echo $PATH
and you will see all path:
/Users/name/.rvm/gems/ruby-2.5.1@pe/bin:/Users/name/.rvm/gems/ruby-2.5.1@global/bin:/Users/sasha/.rvm/rubies/ruby-2.5.1/bin:/Users/sasha/.rvm/bin:
I'd use request for this:
request('http://google.com/doodle.png').pipe(fs.createWriteStream('doodle.png'))
Or if you don't need to save to a file first, and you just need to read the CSV into memory, you can do the following:
var request = require('request');
request.get('http://www.whatever.com/my.csv', function (error, response, body) {
if (!error && response.statusCode == 200) {
var csv = body;
// Continue with your processing here.
}
});
etc.
rows = a.shape[0] # 2
cols = a.shape[1] # 2
a.shape #(2,2)
a.size # rows * cols = 4
Old question but what I've found is that, all you need is to add the ppk file. Settings -> Connections -> SFTP -> Add keyfile User name and the host is same as what you would provide when using putty which is mentioned in http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-connect-to-instance-linux.html Might help someone.
I did not see any mention of it in the other answers, so here are my 2 Canadian cents:
On the "using namespace" topic, a useful statement is the namespace alias, allowing you to "rename" a namespace, normally to give it a shorter name. For example, instead of:
Some::Impossibly::Annoyingly::Long:Name::For::Namespace::Finally::TheClassName foo;
Some::Impossibly::Annoyingly::Long:Name::For::Namespace::Finally::AnotherClassName bar;
you can write:
namespace Shorter = Some::Impossibly::Annoyingly::Long:Name::For::Namespace::Finally;
Shorter::TheClassName foo;
Shorter::AnotherClassName bar;
Google have restricted write access to the external sdcard. From API 19 there is a framework called Storage Access Framework which allows you the set up "contracts" to allow write access.

A dialect is a form of the language that is spoken by a particular group of people.
Here, in context of hibernate framework, When hibernate wants to talk(using queries) with the database it uses dialects.
The SQL dialect's are derived from the Structured Query Language which uses human-readable expressions to define query statements.
A hibernate dialect gives information to the framework of how to convert hibernate queries(HQL) into native SQL queries.
The dialect of hibernate can be configured using below property:
hibernate.dialect
Here, is a complete list of hibernate dialects.
Note: The dialect property of hibernate is not mandatory.
You can use pure Javascript to achieve this:
var test = true;
if (typeof test === 'boolean')
console.log('test is a boolean!');
Maybe it's gotten a little simpler, but below is what I've come up with now in 2017:
class obj {
constructor(in_shape, in_color){
this.shape = in_shape;
this.color = in_color;
}
getInfo(){
return this.shape + ' and ' + this.color;
}
setShape(in_shape){
this.shape = in_shape;
}
setColor(in_color){
this.color = in_color;
}
}
In using the class above, I have the following:
var newobj = new obj('square', 'blue');
//Here, we expect to see 'square and blue'
console.log(newobj.getInfo());
newobj.setColor('white');
newobj.setShape('sphere');
//Since we've set new color and shape, we expect the following: 'sphere and white'
console.log(newobj.getInfo());
As you can see, the constructor takes in two parameters, and we set the object's properties. We also alter the object's color and shape by using the setter
functions, and prove that its change remained upon calling getInfo()
after these changes.
A bit late, but I hope this helps. I've tested this with a mocha
unit-testing, and it's working well.

0xe0434352 is the SEH code for a CLR exception. If you don't understand what that means, stop and read A Crash Course on the Depths of Win32™ Structured Exception Handling. So your process is not handling a CLR exception. Don't shoot the messenger, KERNELBASE.DLL is just the unfortunate victim. The perpetrator is MyApp.exe.
There should be a minidump of the crash in DrWatson folders with a full stack, it will contain everything you need to root cause the issue.
I suggest you wire up, in your myapp.exe code, AppDomain.UnhandledException
and Application.ThreadException
, as appropriate.

You may try this:
Cookie::queue($name, $value, $minutes);
This will queue the cookie to use it later and later it will be added with the response when response is ready to be sent. You may check the documentation on Laravel

):
$value = Cookie::get('name');
Note: If you set a cookie in the current request then you'll be able to retrieve it on the next subsequent request.

This is working for me, you might change your code like this
var responseData=x.toString();
to
var responseData=x.toString("binary");
and finally
response.write(new Buffer(toTransmit, "binary"));
I wrote with parameters that are predefined
They are not "predefined" logically, somewhere inside your code. But as arguments of SP they have no default values and are required. To avoid passing those params explicitly you have to define default values in SP definition:
Alter Procedure [Test]
@StartDate AS varchar(6) = NULL,
@EndDate AS varchar(6) = NULL
AS
...
NULLs or empty strings or something more sensible - up to you. It does not matter since you are overwriting values of those arguments in the first lines of SP.
Now you can call it without passing any arguments e.g.
exec dbo.TEST
Expanding on what others have said I will give a short example.
If you have a 1D array ...
>>> import numpy as np
>>> x = np.arange(4) # array([0, 1, 2, 3])
>>> x[::-1] # returns a view
Out[1]:
array([3, 2, 1, 0])
But if you are working with a 2D array ...
>>> x = np.arange(10).reshape(2, 5)
>>> x
Out[2]:
array([[0, 1, 2, 3, 4],
[5, 6, 7, 8, 9]])
>>> x[::-1] # returns a view:
Out[3]: array([[5, 6, 7, 8, 9],
[0, 1, 2, 3, 4]])
This does not actually reverse the Matrix.
Should use np.flip to actually reverse the elements
>>> np.flip(x)
Out[4]: array([[9, 8, 7, 6, 5],
[4, 3, 2, 1, 0]])
If you want to print the elements of a matrix one-by-one use flat along with flip
>>> for el in np.flip(x).flat:
>>> print(el, end = ' ')
9 8 7 6 5 4 3 2 1 0
