In Windows, capitalization in paths doesn't matter. In Linux it does.
When you autoload, use "Foo" not "foo".
I believe that will do the trick.
I think it works when you take it out of autoloading because codeigniter is smart enough to figure out the capitalization in the path and classes are case independent in php.
The way this effect works is very simple. The element is given a background which is the gradient. It goes from one color to another depending on the colors and color-stop percentages given for it.
For example, in rainbow text sample (note that I've converted the gradient into the standard syntax):
#f22
at 0%
(that is the left edge of the element). First color is always assumed to start at 0%
even though the percentage is not mentioned explicitly.0%
to 14.25%
, the color changes from #f22
to #f2f
gradually. The percenatge is set at 14.25
because there are seven color changes and we are looking for equal splits.14.25%
(of the container's size), the color will exactly be #f2f
as per the gradient specified.14.25%
.So, we end up getting a gradient like in the below snippet. Now this alone would mean the background applies to the entire element and not just the text.
.rainbow {_x000D_
background-image: linear-gradient(to right, #f22, #f2f 14.25%, #22f 28.5%, #2ff 42.75%, #2f2 57%, #2f2 71.25%, #ff2 85.5%, #f22);_x000D_
color: transparent;_x000D_
}
_x000D_
<span class="rainbow">Rainbow text</span>
_x000D_
Since, the gradient needs to be applied only to the text and not to the element on the whole, we need to instruct the browser to clip the background from the areas outside the text. This is done by setting background-clip: text
.
(Note that the background-clip: text
is an experimental property and is not supported widely.)
Now if you want the text to have a simple 3 color gradient (that is, say from red - orange - brown), we just need to change the linear-gradient specification as follows:
to right
. If it should be red at right and brown at left then give the direction as to left
.red
as the first color (percentage is assumed to be 0%).50%
the color should be orange
and then the final color would be brown
. The position of the final color is always assumed to be at 100%.Thus the gradient's specification should read as follows:
background-image: linear-gradient(to right, red, orange 50%, brown).
If we form the gradients using the above mentioned method and apply them to the element, we can get the required effect.
.red-orange-brown {_x000D_
background-image: linear-gradient(to right, red, orange 50%, brown);_x000D_
color: transparent;_x000D_
-webkit-background-clip: text;_x000D_
background-clip: text;_x000D_
}_x000D_
.green-yellowgreen-yellow-gold {_x000D_
background-image: linear-gradient(to right, green, yellowgreen 33%, yellow 66%, gold);_x000D_
color: transparent;_x000D_
-webkit-background-clip: text;_x000D_
background-clip: text;_x000D_
}
_x000D_
<span class="red-orange-brown">Red to Orange to Brown</span>_x000D_
_x000D_
<br>_x000D_
_x000D_
<span class="green-yellowgreen-yellow-gold">Green to Yellow-green to Yellow to Gold</span>
_x000D_
For setting the first color to be seen on screen, you can also do it in the relevant layout.xml (better design) by adding this property to the relevant View:
android:background="#FF00FF00"
require(reshape2)
T <- melt(df, id = c("A"))
T <- dcast(T, A ~ variable, sum)
I am not certain the exact advantages over aggregate.
There is a way to cleanup workspace in Jenkins. You can clean up the workspace before build or after build.
First, install Workspace Cleanup Plugin.
To clean up the workspace before build: Under Build Environment, check the box that says Delete workspace before build starts.
To clean up the workspace after the build: Under the heading Post-build Actions select Delete workspace when build is done from the Add Post-build Actions drop down menu.
By adding a custom view with the background color of your own you can have a custom selection style in table view.
let customBGColorView = UIView()
customBGColorView.backgroundColor = UIColor(hexString: "#FFF900")
cellObj.selectedBackgroundView = customBGColorView
Add this 3 line code in cellForRowAt method of TableView. I have used an extension in UIColor to add color with hexcode. Put this extension code at the end of any Class(Outside the class's body).
extension UIColor {
convenience init(hexString: String) {
let hex = hexString.trimmingCharacters(in: CharacterSet.alphanumerics.inverted)
var int = UInt32()
Scanner(string: hex).scanHexInt32(&int)
let a, r, g, b: UInt32
switch hex.characters.count {
case 3: // RGB (12-bit)
(a, r, g, b) = (255, (int >> 8) * 17, (int >> 4 & 0xF) * 17, (int & 0xF) * 17)
case 6: // RGB (24-bit)
(a, r, g, b) = (255, int >> 16, int >> 8 & 0xFF, int & 0xFF)
case 8: // ARGB (32-bit)
(a, r, g, b) = (int >> 24, int >> 16 & 0xFF, int >> 8 & 0xFF, int & 0xFF)
default:
(a, r, g, b) = (255, 0, 0, 0)
}
self.init(red: CGFloat(r) / 255, green: CGFloat(g) / 255, blue: CGFloat(b) / 255, alpha: CGFloat(a) / 255)
}
}
Best way to send html formatted Email
This code will be in "Customer.htm"
<table>
<tr>
<td>
Dealer's Company Name
</td>
<td>
:

<td>

</tr>
</table>
Read HTML file Using System.IO.File.ReadAllText. get all HTML code in string variable.
string Body = System.IO.File.ReadAllText(HttpContext.Current.Server.MapPath("EmailTemplates/Customer.htm"));
Replace Particular string to your custom value.
Body = Body.Replace("#DealerCompanyName#", _lstGetDealerRoleAndContactInfoByCompanyIDResult[0].CompanyName);
call SendEmail(string Body) Function and do procedure to send email.
public static void SendEmail(string Body)
{
MailMessage message = new MailMessage();
message.From = new MailAddress(Session["Email"].Tostring());
message.To.Add(ConfigurationSettings.AppSettings["RequesEmail"].ToString());
message.Subject = "Request from " + SessionFactory.CurrentCompany.CompanyName + " to add a new supplier";
message.IsBodyHtml = true;
message.Body = Body;
SmtpClient smtpClient = new SmtpClient();
smtpClient.UseDefaultCredentials = true;
smtpClient.Host = ConfigurationSettings.AppSettings["SMTP"].ToString();
smtpClient.Port = Convert.ToInt32(ConfigurationSettings.AppSettings["PORT"].ToString());
smtpClient.EnableSsl = true;
smtpClient.Credentials = new System.Net.NetworkCredential(ConfigurationSettings.AppSettings["USERNAME"].ToString(), ConfigurationSettings.AppSettings["PASSWORD"].ToString());
smtpClient.Send(message);
}
FWIW, I don't see that anyone solved this in quite the same way as I needed to. No complaints at compile time, but I was getting a null view at runtime, and calling things in the proper order. That is, findViewById() after setContentView(). The problem turned out that my view is defined in content_main.xml, but in my activity_main.xml, I lacked this one statement:
<include layout="@layout/content_main" />
When I added that to activity_main.xml, no more NullPointer.
CPMSifDlg::EncodeAndSend()
method is declared as non-static
and thus it must be called using an object of CPMSifDlg
. e.g.
CPMSifDlg obj;
return obj.EncodeAndSend(firstName, lastName, roomNumber, userId, userFirstName, userLastName);
If EncodeAndSend
doesn't use/relate any specifics of an object (i.e. this
) but general for the class CPMSifDlg
then declare it as static
:
class CPMSifDlg {
...
static int EncodeAndSend(...);
^^^^^^
};
Another common use is for std containers to do equality comparison on key values inside custom objects
class Foo
{
public: int val;
};
class Comparer { public:
bool operator () (Foo& a, Foo&b) const {
return a.val == b.val;
};
class Blah
{
std::set< Foo, Comparer > _mySet;
};
here it is, obtaining a reference to the coresponding pointer of an iterator use :
example:
string my_str= "hello world";
string::iterator it(my_str.begin());
char* pointer_inside_buffer=&(*it); //<--
[notice operator * returns a reference so doing & on a reference will give you the address].
Let's add one more similar solution to the stack. This one also parses enums, and it looks nice. Very safe.
/// <summary>
/// <para>More convenient than using T.TryParse(string, out T).
/// Works with primitive types, structs, and enums.
/// Tries to parse the string to an instance of the type specified.
/// If the input cannot be parsed, null will be returned.
/// </para>
/// <para>
/// If the value of the caller is null, null will be returned.
/// So if you have "string s = null;" and then you try "s.ToNullable...",
/// null will be returned. No null exception will be thrown.
/// </para>
/// <author>Contributed by Taylor Love (Pangamma)</author>
/// </summary>
/// <typeparam name="T"></typeparam>
/// <param name="p_self"></param>
/// <returns></returns>
public static T? ToNullable<T>(this string p_self) where T : struct
{
if (!string.IsNullOrEmpty(p_self))
{
var converter = System.ComponentModel.TypeDescriptor.GetConverter(typeof(T));
if (converter.IsValid(p_self)) return (T)converter.ConvertFromString(p_self);
if (typeof(T).IsEnum) { T t; if (Enum.TryParse<T>(p_self, out t)) return t;}
}
return null;
}
In Ruby 1.9.3 it is possible to use String.encode to "ignore" the invalid UTF-8 sequences. Here is a snippet that will work both in 1.8 (iconv) and 1.9 (String#encode) :
require 'iconv' unless String.method_defined?(:encode)
if String.method_defined?(:encode)
file_contents.encode!('UTF-8', 'UTF-8', :invalid => :replace)
else
ic = Iconv.new('UTF-8', 'UTF-8//IGNORE')
file_contents = ic.iconv(file_contents)
end
or if you have really troublesome input you can do a double conversion from UTF-8 to UTF-16 and back to UTF-8:
require 'iconv' unless String.method_defined?(:encode)
if String.method_defined?(:encode)
file_contents.encode!('UTF-16', 'UTF-8', :invalid => :replace, :replace => '')
file_contents.encode!('UTF-8', 'UTF-16')
else
ic = Iconv.new('UTF-8', 'UTF-8//IGNORE')
file_contents = ic.iconv(file_contents)
end
If you happen to use Vavr(formerly known as Javaslang), you can leverage the dedicated method:
Stream.of("A", "B", "C")
.zipWithIndex();
If we print out the content, we will see something interesting:
Stream((A, 0), ?)
This is because Streams
are lazy and we have no clue about next items in the stream.
If I understand well, you want to Join ScheduleRequest
with User
and apply the in
clause to the userName
property of the entity User
.
I'd need to work a bit on this schema. But you can try with this trick, that is much more readable than the code you posted, and avoids the Join
part (because it handles the Join
logic outside the Criteria Query).
List<String> myList = new ArrayList<String> ();
for (User u : usersList) {
myList.add(u.getUsername());
}
Expression<String> exp = scheduleRequest.get("createdBy");
Predicate predicate = exp.in(myList);
criteria.where(predicate);
In order to write more type-safe code you could also use Metamodel by replacing this line:
Expression<String> exp = scheduleRequest.get("createdBy");
with this:
Expression<String> exp = scheduleRequest.get(ScheduleRequest_.createdBy);
If it works, then you may try to add the Join
logic into the Criteria Query
. But right now I can't test it, so I prefer to see if somebody else wants to try.
Not a perfect answer though may be code snippets might help.
public <T> List<T> findListWhereInCondition(Class<T> clazz,
String conditionColumnName, Serializable... conditionColumnValues) {
QueryBuilder<T> queryBuilder = new QueryBuilder<T>(clazz);
addWhereInClause(queryBuilder, conditionColumnName,
conditionColumnValues);
queryBuilder.select();
return queryBuilder.getResultList();
}
private <T> void addWhereInClause(QueryBuilder<T> queryBuilder,
String conditionColumnName, Serializable... conditionColumnValues) {
Path<Object> path = queryBuilder.root.get(conditionColumnName);
In<Object> in = queryBuilder.criteriaBuilder.in(path);
for (Serializable conditionColumnValue : conditionColumnValues) {
in.value(conditionColumnValue);
}
queryBuilder.criteriaQuery.where(in);
}
Try this
function readRows() {
var sheet = SpreadsheetApp.getActiveSheet();
var rows = sheet.getDataRange();
var numRows = rows.getNumRows();
//var values = rows.getValues();
var Names = sheet.getRange("A2:A7");
var Name = [
Names.getCell(1, 1).getValue(),
Names.getCell(2, 1).getValue(),
.....
Names.getCell(5, 1).getValue()]
You can define arrays simply as follows, instead of allocating and then assigning.
var arr = [1,2,3,5]
Your initial error was because of the following line, and ones like it
var Name[0] = Name_cell.getValue();
Since Name
is already defined and you are assigning the values to its elements, you should skip the var
, so just
Name[0] = Name_cell.getValue();
Pro tip: For most issues that, like this one, don't directly involve Google services, you are better off Googling for the way to do it in javascript in general.
This works in Chrome, Firefox, doesn't work in Safari :(, haven't tested in other browsers

To Enter into crontab :
crontab -e
write this into the file:
0 */2 * * * python/php/java yourfilepath
Example :0 */2 * * * python ec2-user/home/demo.py
and make sure you have keep one blank line after the last cron job in your crontab file
You need either of the following depending on the type of the container of T
elements you pass to the builder (Collection<T>
or T[]
):
Collection<T> YOUR_COLLECTION
:Collections.unmodifiableList(new ArrayList<>(YOUR_COLLECTION));
T[] YOUR_ARRAY
:Arrays.asList(YOUR_ARRAY);
Simple as that
$('#StartButton:disabled') ..
Then check if it's undefined.
For others that stumble on this, you can also use ejs params/props in conditional statements:
recipes.js File:
app.get("/recipes", function(req, res) {
res.render("recipes.ejs", {
recipes: recipes
});
});
recipes.ejs File:
<%if (recipes.length > 0) { %>
// Do something with more than 1 recipe
<% } %>
If you setup your select like the following:
<select ng-model="myselect" ng-options="b for b in options track by b"></select>
you will get:
<option value="var1">var1</option>
<option value="var2">var2</option>
<option value="var3">var3</option>

You can also use chmod 777 *
This will give permissions to all files currently in the folder and files added in the future without giving permissions to the directory itself.
NOTE: This should be done in the folder where the files are located. For me it was an images that had an issue so I went to my images folder and did this.
In more simple terms:
Technically, the -u
flag adds a tracking reference to the upstream server you are pushing to.
What is important here is that this lets you do a git pull
without supplying any more arguments. For example, once you do a git push -u origin master
, you can later call git pull
and git will know that you actually meant git pull origin master
.
Otherwise, you'd have to type in the whole command.
You'll need to open the workbook to refer to it.
Sub Setwbk()
Dim wbk As Workbook
Set wbk = Workbooks.Open("F:\Quarterly Reports\2012 Reports\New Reports\ _
Master Benchmark Data Sheet.xlsx")
End Sub
* Follow Doug's answer if the workbook is already open. For the sake of making this answer as complete as possible, I'm including my comment on his answer:
Why do I have to "set" it?
Set
is how VBA assigns object variables. Since a Range
and a Workbook
/Worksheet
are objects, you must use Set
with these.
If it cannot be avoided the suggested pattern extracted from the React docs would be:
import React, { Component } from 'react';
const Child = ({ setRef }) => <input type="text" ref={setRef} />;
class Parent extends Component {
constructor(props) {
super(props);
this.setRef = this.setRef.bind(this);
}
componentDidMount() {
// Calling a function on the Child DOM element
this.childRef.focus();
}
setRef(input) {
this.childRef = input;
}
render() {
return <Child setRef={this.setRef} />
}
}
The Parent forwards a function as prop bound to Parent's this
. When React calls the Child's ref
prop setRef
it will assign the Child's ref
to the Parent's childRef
property.
Ref forwarding is an opt-in feature that lets some components take a ref they receive, and pass it further down (in other words, “forward” it) to a child.
We create Components that forward their ref
with React.forwardRef
.
The returned Component ref prop must be of the same type as the return type of React.createRef
. Whenever React mounts the DOM node then property current
of the ref
created with React.createRef
will point to the underlying DOM node.
import React from "react";
const LibraryButton = React.forwardRef((props, ref) => (
<button ref={ref} {...props}>
FancyButton
</button>
));
class AutoFocus extends React.Component {
constructor(props) {
super(props);
this.childRef = React.createRef();
this.onClick = this.onClick.bind(this);
}
componentDidMount() {
this.childRef.current.focus();
}
onClick() {
console.log("fancy!");
}
render() {
return <LibraryButton onClick={this.onClick} ref={this.childRef} />;
}
}
Created Components are forwarding their ref
to a child node.
function logProps(Component) {
class LogProps extends React.Component {
componentDidUpdate(prevProps) {
console.log('old props:', prevProps);
console.log('new props:', this.props);
}
render() {
const {forwardedRef, ...rest} = this.props;
// Assign the custom prop "forwardedRef" as a ref
return <Component ref={forwardedRef} {...rest} />;
}
}
// Note the second param "ref" provided by React.forwardRef.
// We can pass it along to LogProps as a regular prop, e.g. "forwardedRef"
// And it can then be attached to the Component.
return React.forwardRef((props, ref) => {
return <LogProps {...props} forwardedRef={ref} />;
});
}

Just to extend the answer above you can also index your columns rather than specifying the column names which can also be useful depending on what you're doing. Given that your location is the first field it would look like this:
bar <- foo[foo[ ,1] == "there", ]
This is useful because you can perform operations on your column value, like looping over specific columns (and you can do the same by indexing row numbers too).
This is also useful if you need to perform some operation on more than one column because you can then specify a range of columns:
foo[foo[ ,c(1:N)], ]
Or specific columns, as you would expect.
foo[foo[ ,c(1,5,9)], ]
Could you not just have a different Draw method for each type that you want to Draw? Then call the overloaded Draw method passing in the object of type itemType to be drawn.
Your question does not make it clear whether itemType genuinely refers to objects of differing types.
Another version of Singleton where the following line of code creates the Singleton instance at the time of application startup.

Simply check that the directory/package of the class is marked as "Sources Root". I believe the package should be application or execution in your case.

Despite all good hints, the only thing that helped me, and that I'd like to share just in case, if everything else does not work :
Remove your .gradle directory in your home directory and have it re-build/re-downloaded for you by Android Studio.
Fixed all kinds of weird errors for me that neither were fixable by re-installing Android Studio itself nor the SDK.
Nice answers. You could also set Jobs (i.e., commands) with "Crontab" for more flexibility (which provides different options to run scripts, loggin the outputs, etc.), although it requires more time to be understood and set properly:
Using '@reboot' you can Run a command once, at startup.
Wrapping up:
run $ sudo crontab -e -u root
And add a line at the end of the file with your command as follows:
@reboot sudo searchd
when we pass vector by value in a function as an argument,it simply creates the copy of vector and no any effect happens on the vector which is defined in main function when we call that particular function. while when we pass vector by reference whatever is written in that particular function, every action will going to perform on the vector which is defined in main or other function when we call that particular function.
I find that no one mentions this difference:
__getattribute__
has a default implementation, but __getattr__
does not.
class A:
pass
a = A()
a.__getattr__ # error
a.__getattribute__ # return a method-wrapper
This has a clear meaning: since __getattribute__
has a default implementation, while __getattr__
not, clearly python encourages users to implement __getattr__
.
put this at the end of your template :
var scripts = document.getElementsByTagName('script');
var torefreshs = ['myscript.js', 'myscript2.js'] ; // list of js to be refresh
var key = 1; // change this key every time you want force a refresh
for(var i=0;i<scripts.length;i++){
for(var j=0;j<torefreshs.length;j++){
if(scripts[i].src && (scripts[i].src.indexOf(torefreshs[j]) > -1)){
new_src = scripts[i].src.replace(torefreshs[j],torefreshs[j] + 'k=' + key );
scripts[i].src = new_src; // change src in order to refresh js
}

Essentially equating to 'do default', since we're no longer preventing it.
Otherwise I'm inclined to point you to the answers provided by another comments and answers:
How to unbind a listener that is calling event.preventDefault() (using jQuery)?
How to reenable event.preventDefault?
Note that the second one has been accepted with an example solution, given by redsquare (posted here for a direct solution in case this isn't closed as duplicate):
$('form').submit( function(ev) {
ev.preventDefault();
//later you decide you want to submit
$(this).unbind('submit').submit()
});
To get a definitive reason, you'd need to ask the designer(s) of that API.
But one possible reason is that the intent of a (hypothetical) nextChar
would not fit into the scanning model very well.
If nextChar()
to behaved like read()
on a Reader
and simply returned the next unconsumed character from the scanner, then it is behaving inconsistently with the other next<Type>
methods. These skip over delimiter characters before they attempt to parse a value.
If nextChar()
to behaved like (say) nextInt
then:
the delimiter skipping would be "unexpected" for some folks, and
there is the issue of whether it should accept a single "raw" character, or a sequence of digits that are the numeric representation of a char
, or maybe even support escaping or something1.
No matter what choice they made, some people wouldn't be happy. My guess is that the designers decided to stay away from the tarpit.
1 - Would vote strongly for the raw character approach ... but the point is that there are alternatives that need to be analysed, etc.
The solutions based on git show-branch -a
plus some filters have one downside: git may consider a branch name of a short lived branch.
If you have a few possible parents which you care about, you can ask yourself this similar question (and probably the one the OP wanted to know about):
From a specific subset of all branches, which is the nearest parent of a git branch?
To simplify, I'll consider "a git branch" to refer to HEAD
(i.e., the current branch).
Let's imagine that we have the following branches:
HEAD
important/a
important/b
spam/a
spam/b
The solutions based on git show-branch -a
+ filters, may give that the nearest parent of HEAD
is spam/a
, but we don't care about that.
If we want to know which of important/a
and important/b
is the closest parent of HEAD
, we could run the following:
for b in $(git branch -a -l "important/*"); do
d1=$(git rev-list --first-parent ^${b} HEAD |wc -l);
d2=$(git rev-list --first-parent ^HEAD ${b} |wc -l);
echo "${b} ${d1} ${d2}";
done \
|sort -n -k2 -k3 \
|head -n1 \
|awk '{print $1}';
What it does:
1.) $(git branch -a -l "important/*")
: Print a list of all branches with some pattern ("important/*"
).
2.) d=$(git rev-list --first-parent ^${b} HEAD |wc -l);
: For each of those branches ($b
), calculate the distance ($d1
) in number of commits, from HEAD
to the nearest commit in $b
(similar to when you calculate the distance from a point to a line). You may want to consider the distance differently here: you may not want to use --first-parent
, or may want distance from tip to the tip of the branches ("${b}"...HEAD
), ...
2.2) d2=$(git rev-list --first-parent ^HEAD ${b} |wc -l);
: For each of those branches ($b
), calculate the distance ($d2
) in number of commits from the tip of the branch to the nearest commit in HEAD
. We will use this distance to choose between two branches whose distance $d1
was equal.
3.) echo "${b} ${d1} ${d2}";
: Print the name of each of the branches, followed by the distances to be able to sort them later (first $d1
, and then $d2
).
4.) |sort -n -k2 -k3
: Sort the previous result, so we get a sorted (by distance) list of all of the branches, followed by their distances (both).
5.) |head -n1
: The first result of the previous step will be the branch that has a smaller distance, i.e., the closest parent branch. So just discard all other branches.
6.) |awk '{print $1}';
: We only care about the branch name, and not about the distance, so extract the first field, which was the parent's name. Here it is! :)
There is a more efficient way of doing this in Windows 7. SETX is installed by default and supports connecting to other systems.
To modify a remote system's global environment variables, you would use
setx /m /s HOSTNAME-GOES-HERE VariableNameGoesHere VariableValueGoesHere
This does not require restarting Windows Explorer.
Maybe this trick gives u an idea
Boolean var= new anonymousClass(){
private String myVar; //String for example
@Overriden public Boolean method(int i){
//use myVar and i
}
public String setVar(String var){myVar=var; return this;} //Returns self instane
}.setVar("Hello").method(3);
it's my understanding that target = whatever
will look for a frame/window with that name. If not found, it will open up a new window with that name. If whatever == "_new"
, it will appear just as if you used _blank
except.....
Using one of the reserved target names will bypass the "looking" phase. So, target = "_blank"
on a dozen links will open up a dozen blank windows, but target = whatever
on a dozen links will only open up one window. target = "_new"
on a dozen links may give inconstant behavior. I haven't tried it on several browsers, but should only open up one window.
At least this is how I interpret the rules.
I'm guessing that you're doing some sort of localization, so have a look at this script.
First thing that comes into my mind:
read -r a b c <<<$(echo 1 2 3) ; echo "$a|$b|$c"
output is, unsurprisingly
1|2|3
I would suggest starting with the most straightforward solutions first - maybe simple HTTP Basic Authentication + HTTPS is enough in your scenario.
If not (for example you cannot use https, or need more complex key management), you may have a look at HMAC-based solutions as suggested by others. A good example of such API would be Amazon S3 (http://s3.amazonaws.com/doc/s3-developer-guide/RESTAuthentication.html)
I wrote a blog post about HMAC based authentication in ASP.NET Web API. It discusses both Web API service and Web API client and the code is available on bitbucket. http://www.piotrwalat.net/hmac-authentication-in-asp-net-web-api/
Here is a post about Basic Authentication in Web API: http://www.piotrwalat.net/basic-http-authentication-in-asp-net-web-api-using-message-handlers/
Remember that if you are going to provide an API to 3rd parties, you will also most likely be responsible for delivering client libraries. Basic authentication has a significant advantage here as it is supported on most programming platforms out of the box. HMAC, on the other hand, is not that standardized and will require custom implementation. These should be relatively straightforward but still require work.
PS. There is also an option to use HTTPS + certificates. http://www.piotrwalat.net/client-certificate-authentication-in-asp-net-web-api-and-windows-store-apps/

Make UIImageView
and UILabel
, and set image and text to both of this....then Place a custom button over imageView and Label....
UIImageView *imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"search.png"]];
imageView.frame = CGRectMake(x, y, imageView.frame.size.width, imageView.frame.size.height);
[self.view addSubview:imageView];
UILabel *yourLabel = [[UILabel alloc] initWithFrame:CGRectMake(x, y,a,b)];
yourLabel.text = @"raj";
[self.view addSubview:yourLabel];
UIButton * yourBtn=[UIButton buttonWithType:UIButtonTypeCustom];
[yourBtn setFrame:CGRectMake(x, y,c,d)];
[yourBtn addTarget:self action:@selector(@"Your Action") forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:yourBtn];
I would suggest using absolute positioning within the element.
I've created this to help you visualize it a bit.

You can consider to replace default WordPress jQuery script with Google Library by adding something like the following into theme functions.php file:
function modify_jquery() {
if (!is_admin()) {
wp_deregister_script('jquery');
wp_register_script('jquery', 'http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js', false, '1.10.2');
wp_enqueue_script('jquery');
}
}
add_action('init', 'modify_jquery');
Code taken from here: http://www.wpbeginner.com/wp-themes/replace-default-wordpress-jquery-script-with-google-library/
s
is an uninitialized pointer; you are writing to a random location in memory. This will invoke undefined behaviour.
You need to allocate some memory for s
. Also, never use gets
; there is no way to prevent it overflowing the memory you allocate. Use fgets
instead.
You can't remove, nor can you add to a fixed-size-list of Arrays.
But you can create your sublist from that list.
list = list.subList(0, list.size() - (list.size() - count));
public static String SelectRandomFromTemplate(String template, int count) {
String[] split = template.split("\\|");
List<String> list = Arrays.asList(split);
Random r = new Random();
while( list.size() > count ) {
list = list.subList(0, list.size() - (list.size() - count));
}
return StringUtils.join(list, ", ");
}
*Other way is
ArrayList<String> al = new ArrayList<String>(Arrays.asList(template));
this will create ArrayList which is not fixed size like Arrays.asList
public class BinaryConvert{
public static void main(String[] args){
System.out.println("Binary Result: "+ doBin(45));
}
static String doBin(int n){
int b = 2;
String r = "";
String c = "";
do{
c += (n % b);
n /= b;
}while(n != 0);
for(int i = (c.length() - 1); i >=0; i--){
r += c.charAt(i);
}
return r;
}
}
You can append to your PATH
in a minimal fashion. No need for
parentheses unless you're appending more than one element. It also
usually doesn't need quotes. So the simple, short way to append is:
path+=/some/new/bin/dir
This lower-case syntax is using path
as an array, yet also
affects its upper-case partner equivalent, PATH
(to which it is
"bound" via typeset
).
(Notice that no :
is needed/wanted as a separator.)
Then the common pattern for testing a new script/executable becomes:
path+=$PWD/.
# or
path+=$PWD/bin
You can sprinkle path settings around your .zshrc
(as above) and it will naturally lead to the earlier listed settings taking precedence (though you may occasionally still want to use the "prepend" form path=(/some/new/bin/dir $path)
).
Treating path
this way (as an array) also means: no need to do a
rehash
to get the newly pathed commands to be found.
Also take a look at vared path
as a dynamic way to edit path
(and other things).
You may only be interested in path
for this question, but since
we're talking about exports and arrays, note that
arrays generally cannot be exported.
You can even prevent PATH
from taking on duplicate entries
(refer to
this
and this):
typeset -U path
Mostly we write below statement select * from table where length(ltrim(rtrim(field)))=10;
Get or set the length of vectors (including lists) and factors, and of any other R object for which a method has been defined.
Get the length of each element of a list or atomic vector (is.atomic) as an integer or numeric vector.
some symbols should be transferred like '%'
<string name="test" formatted="false">95%</string>
You are providing a string representation of a dict to the DataFrame constructor, and not a dict itself. So this is the reason you get that error.
So if you want to use your code, you could do:
df = DataFrame(eval(data))
But better would be to not create the string in the first place, but directly putting it in a dict. Something roughly like:
data = []
for row in result_set:
data.append({'value': row["tag_expression"], 'key': row["tag_name"]})
But probably even this is not needed, as depending on what is exactly in your result_set
you could probably:
DataFrame(result_set)
read_sql_query

toolbarHeight
property in your AppBarExample :
AppBar(
title: Text('Flutter is great'),
toolbarHeight: 100,
),
You can add
flexibleSpace
property in your appBar for more flexibility
Output:
Example :
appBar: PreferredSize(
preferredSize: Size(100, 80), //width and height
// The size the AppBar would prefer if there were no other constraints.
child: SafeArea(
child: Container(
height: 100,
color: Colors.red,
child: Center(child: Text('Fluter is great')),
),
),
),
Don't forget to use a
SafeArea
widget if you don't have a safeArea
Output :
The padding options padx
and pady
of the grid
and pack
methods can take a 2-tuple that represent the left/right and top/bottom padding.
Here's an example:
import tkinter as tk
class MyApp():
def __init__(self):
self.root = tk.Tk()
l1 = tk.Label(self.root, text="Hello")
l2 = tk.Label(self.root, text="World")
l1.grid(row=0, column=0, padx=(100, 10))
l2.grid(row=1, column=0, padx=(10, 100))
app = MyApp()
app.root.mainloop()
I just installed Sublime 3, the 64 bit version, on Ubuntu 14.04. I can't tell the difference between this version and Sublime 2 as far as user interface. The reason I didn't go with Sublime 2 is that it gives an annoying "GLib critical" error messages.
Anyways - previous posts mentioned the file
/sublime_text_3/Packages/Color\ Scheme\ -\ Default.sublime-package
I wanted to give two tips here with respect to this file in Sublime 3:
^W
to search the theme name. The first search
result will bring you to an XML style entry where you can change the values. Make a copy
before you experiment.~/.config/sublime-text-3/Cache/Color Scheme - Default/
The SQL is somewhat like the syntax of MS SQL.
SELECT * FROM [table$] WHERE *;
It is important that the table name is ended with a $ sign and the whole thing is put into brackets. As conditions you can use any value, but so far Excel didn't allow me to use what I call "SQL Apostrophes" (´), so a column title in one word is recommended.
If you have users listed in a table called "Users", and the id is in a column titled "id" and the name in a column titled "Name", your query will look like this:
SELECT Name FROM [Users$] WHERE id = 1;
Hope this helps.
In the later PHP version self::staticMethod();
also will not work. It will throw the strict standard error.
In this case, we can create object of same class and call by object
here is the example
class Foo {
public function fun1() {
echo 'non-static';
}
public static function fun2() {
echo (new self)->fun1();
}
}
Using jj
In my case, the .vimrc (or in gVim it is in _vimrc
) setting below.
inoremap jj <Esc> """ jj key is <Esc> setting
If you are sure that your structure is correct, just push an empty commit or update the index.html file with some space, it works!
If you check the API for List
you'll notice it says:
Interface List<E>
Being an interface
means it cannot be instantiated (no new List()
is possible).
If you check that link, you'll find some class
es that implement List
:
All Known Implementing Classes:
AbstractList
,AbstractSequentialList
,ArrayList
,AttributeList
,CopyOnWriteArrayList
,LinkedList
,RoleList
,RoleUnresolvedList
,Stack
,Vector
Those can be instantiated. Use their links to know more about them, I.E: to know which fits better your needs.
The 3 most commonly used ones probably are:
List<String> supplierNames1 = new ArrayList<String>();
List<String> supplierNames2 = new LinkedList<String>();
List<String> supplierNames3 = new Vector<String>();
Bonus:
You can also instantiate it with values, in an easier way, using the Arrays
class
, as follows:
List<String> supplierNames = Arrays.asList("sup1", "sup2", "sup3");
System.out.println(supplierNames.get(1));
But note you are not allowed to add more elements to that list, as it's fixed-size
.
I just want to write what I have done and what has worked for me (as nothing else I tried had worked).
I had the problem that IE would close the windows before the print dialog got up.
After a lot of trial and error og testing this is what I got to work:
var w = window.open();
w.document.write($('#data').html()); //only part of the page to print, using jquery
w.document.close(); //this seems to be the thing doing the trick
w.focus();
w.print();
w.close();
This seems to work in all browsers.
Increasing the timeout will not likely solve your issue since, as you say, the actual target web server is responding just fine.
I had this same issue and I found it had to do with not using a keep-alive on the connection. I can't actually answer why this is but, in clearing the connection header I solved this issue and the request was proxied just fine:
server {
location / {
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header Host $http_host;
proxy_http_version 1.1;
proxy_set_header Connection "";
proxy_pass http://localhost:5000;
}
}
Have a look at this posts which explains it in more detail: nginx close upstream connection after request Keep-alive header clarification http://nginx.org/en/docs/http/ngx_http_upstream_module.html#keepalive
You need to use brackets when using the fileExists
step in an if
condition or assign the returned value to a variable
Using variable:
def exists = fileExists 'file'
if (exists) {
echo 'Yes'
} else {
echo 'No'
}
Using brackets:
if (fileExists('file')) {
echo 'Yes'
} else {
echo 'No'
}
If you intend to read csv from excel, then there are some interesting corner cases. I can't remember them all, but the apache commons csv was not capable of handling it correctly (with, for example, urls).
Be sure to test excel output with quotes and commas and slashes all over the place.

I haven't used it much, but looks pretty cool
From the site:
rush is a replacement for the unix shell (bash, zsh, etc) which uses pure Ruby syntax. Grep through files, find and kill processes, copy files - everything you do in the shell, now in Ruby
You can do it as simple as this, I did it in react hooks :
(myNumber == 12) ? "true" : "false"
it was equal to this long if function below :
if (myNumber == 12) {
"true"
} else {
"false"
}
Hope it helps ^_^

I really like this method as well, less clutter:

You can try this with Color.FromArgb
:
Random rnd = new Random();
lbl.ForeColor = Color.FromArgb(rnd.Next(255), rnd.Next(255), rnd.Next(255));
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.
Even if the generics problems are fixed in 1.3

In Java 8 and later it could be done in one line using class java.time.LocalTime.
In the formatting pattern, lowercase hh
means 12-hour clock while uppercase HH
means 24-hour clock.
Code example:
String result = // Text representing the value of our date-time object.
LocalTime.parse( // Class representing a time-of-day value without a date and without a time zone.
"03:30 PM" , // Your `String` input text.
DateTimeFormatter.ofPattern( // Define a formatting pattern to match your input text.
"hh:mm a" ,
Locale.US // `Locale` determines the human language and cultural norms used in localization. Needed here to translate the `AM` & `PM` value.
) // Returns a `DateTimeFormatter` object.
) // Return a `LocalTime` object.
.format( DateTimeFormatter.ofPattern("HH:mm") ) // Generate text in a specific format. Returns a `String` object.

You don't really need to do anything manually, await
keyword pauses the function execution until blah()
returns.

var x = await LoadBlahBlah(); <- Function is not paused
//rest of the code get's executed even if LoadBlahBlah() is still executing
}
private async Task<T> LoadBlahBlah()
{
await DoStuff(); <- function is paused
await DoMoreStuff();
}
T
is type of object blah()

You can't really await

Check to see if there are any triggers on the table you are trying to execute queries against. They can sometimes throw this error as they are trying to run the update/select/insert trigger that is on the table.
You can modify your query to disable then enable the trigger if the trigger DOES NOT need to be executed for whatever query you are trying to run.
ALTER TABLE your_table DISABLE TRIGGER [the_trigger_name]
UPDATE your_table
SET Gender = 'Female'
WHERE (Gender = 'Male')
ALTER TABLE your_table ENABLE TRIGGER [the_trigger_name]

is in the path):-
dist/lib

The problem here is in your explode statement
//$item['date'] presumably = 20120514. Do a print of this
$eventDate = trim($item['date']);
//This explodes on , but there is no , in $eventDate
//You also have a limit of 2 set in the below explode statement
$myarray = (explode(',', $eventDate, 2));
//$myarray is currently = to '20'
foreach ($myarray as $value) {
//Now you are iterating through a string
echo $value;
}
Try changing your initial $item['date'] to be 2012,04,30 if that's what you're trying to do. Otherwise I'm not entirely sure what you're trying to print.
I have only recently started dabbling in PowerShell with any degree of seriousness. Although for the past seven years I've worked in an almost exclusively Windows-based environment, I come from a Unix background and find myself constantly trying to "Unix-fy" my interaction experience on Windows. It's frustrating to say the least.
It's only fair to compare PowerShell to something like Bash, tcsh, or zsh since utilities like grep, sed, awk, find, etc. are not, strictly speaking, part of the shell; they will always, however, be part of any Unix environment. That said, a PowerShell command like Select-String has a very similar function to grep and is bundled as a core module in PowerShell ... so the lines can be a little blurred.
I think the key thing is culture, and the fact that the respective tool-sets will embody their respective cultures:
The Unix administrative (and, for many years, development) interface has traditionally been the command line and the virtual terminal. Windows started off as a GUI and administrative functions have only recently started moving away from being exclusively GUI-based. We can expect the Unix experience on the command line to be a richer, more mature one given the significant lead it has on PowerShell, and my experience matches this. On this, in my experience:
The Unix administrative experience is geared towards making things easy to do in a minimal amount of key strokes; this is probably as a result of the historical situation of having to administer a server over a slow 9600 baud dial-up connection. Now PowerShell does have aliases which go a long way to getting around the rather verbose Verb-Noun standard, but getting to know those aliases is a bit of a pain (anyone know of something better than: alias | where {$_.ResolvedCommandName -eq "<command>"}
?).
An example of the rich way in which history can be manipulated:
iptables
commands are often long-winded and repeating them with slight differences would be a pain if it weren't for just one of many neat features of history manipulation built into Bash, so inserting an iptables rule like the following:
iptables -I camera-1-internet -s 192.168.0.50 -m state --state NEW -j ACCEPT
a second time for another camera ("camera-2
"), is just a case of issuing:
!!:s/-1-/-2-/:s/50/51
which means "perform the previous command, but substitute -1-
with -2-
and 50
with 51
.
The Unix experience is optimised for touch-typists; one can pretty much do everything without leaving the "home" position. For example, in Bash, using the Emacs key bindings (yes, Bash also supports vi bindings), cycling through the history is done using Ctrl-P and Ctrl-N whilst moving to the start and end of a line is done using Ctrl-A and Ctrl-E respectively ... and it definitely doesn't end there. Try even the simplest of navigation in the PowerShell console without moving from the home position and you're in trouble.
The Windows culture, at least in terms of system API's is largely driven by the supporting frameworks, viz., COM and .NET, both of-which are highly structured and object-based. On the other hand, access to Unix APIs has traditionally been through a file interface (/dev
and /proc
) or (non-object-oriented) C-style library calls. It's no surprise then that the scripting experiences match their respective OS paradigms. PowerShell is by nature structured (everything is an object) and Bash-and-friends file-based. The structured API which is at the disposal of a PowerShell programmer is vast (essentially matching the vastness of the existing set of standard COM and .NET interfaces).
In short, although the scripting capabilities of PowerShell are arguably more powerful than Bash (especially when you consider the availability of the .NET BCL), the interactive experience is significantly weaker, particularly if you're coming at it from an entirely keyboard-driven, console-based perspective (as many Unix-heads are).
Use the FileUploadParser, it's all in the request. Use a put method instead, you'll find an example in the docs :)
class FileUploadView(views.APIView):
parser_classes = (FileUploadParser,)
def put(self, request, filename, format=None):
file_obj = request.FILES['file']
# do some stuff with uploaded file
return Response(status=204)
Use the GetType() method

Swift implementation:
class KeyboardStateListener: NSObject
{
static var shared = KeyboardStateListener()
var isVisible = false
func start() {
let nc = NSNotificationCenter.defaultCenter()
nc.addObserver(self, selector: #selector(didShow), name: UIKeyboardDidShowNotification, object: nil)
nc.addObserver(self, selector: #selector(didHide), name: UIKeyboardDidHideNotification, object: nil)
}
func didShow()
{
isVisible = true
}
func didHide()
{
isVisible = false
}
}
Because swift doesn't execute class load method on startup it is important to start this service on app launch:
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject : AnyObject]?) -> Bool
{
...
KeyboardStateListener.shared.start()
}
I'm not sure I understand the problem.
I you want to change the status bar color programmatically (and provided the device has Android 5.0) then you can use Window.setStatusBarColor()
. It shouldn't make a difference whether the activity is derived from Activity
or ActionBarActivity
.
Just try doing:
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
Window window = getWindow();
window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
window.setStatusBarColor(Color.BLUE);
}
Just tested this with ActionBarActivity
and it works alright.
Note: Setting the FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS
flag programmatically is not necessary if your values-v21
styles file has it set already, via:
<item name="android:windowDrawsSystemBarBackgrounds">true</item>
http://devcenter.heroku.com/articles/maintenance-mode
If you’re deploying a large migration or need to disable access to your application for some length of time, you can use Heroku’s built in maintenance mode. It will serve a static page to all visitors, while still allowing you to run rake tasks or console commands.
$ heroku maintenance:on
Maintenance mode enabled.
and later
$ heroku maintenance:off
Maintenance mode disabled.
glob2rx()
converts a pattern including a wildcard into the equivalent regular expression. You then need to pass this regular expression onto one of R's pattern matching tools.
If you want to match "blue*"
where *
has the usual wildcard, not regular expression, meaning we use glob2rx()
to convert the wildcard pattern into a useful regular expression:
> glob2rx("blue*")
[1] "^blue"
The returned object is a regular expression.
Given your data:
x <- c('red','blue1','blue2', 'red2')
we can pattern match using grep()
or similar tools:
> grx <- glob2rx("blue*")
> grep(grx, x)
[1] 2 3
> grep(grx, x, value = TRUE)
[1] "blue1" "blue2"
> grepl(grx, x)
[1] FALSE TRUE TRUE FALSE
As for the selecting rows problem you posted
> a <- data.frame(x = c('red','blue1','blue2', 'red2'))
> with(a, a[grepl(grx, x), ])
[1] blue1 blue2
Levels: blue1 blue2 red red2
> with(a, a[grep(grx, x), ])
[1] blue1 blue2
Levels: blue1 blue2 red red2
or via subset()
:
> with(a, subset(a, subset = grepl(grx, x)))
x
2 blue1
3 blue2
Hope that explains what grob2rx()
does and how to use it?
In addition to standard net/http package, you can consider using my GoRequest which wraps around net/http and make your life easier without thinking too much about json or struct. But you can also mix and match both of them in one request! (you can see more details about it in gorequest github page)
So, in the end your code will become like follow:
func main() {
url := "http://restapi3.apiary.io/notes"
fmt.Println("URL:>", url)
request := gorequest.New()
titleList := []string{"title1", "title2", "title3"}
for _, title := range titleList {
resp, body, errs := request.Post(url).
Set("X-Custom-Header", "myvalue").
Send(`{"title":"` + title + `"}`).
End()
if errs != nil {
fmt.Println(errs)
os.Exit(1)
}
fmt.Println("response Status:", resp.Status)
fmt.Println("response Headers:", resp.Header)
fmt.Println("response Body:", body)
}
}
This depends on how you want to achieve. I made this library because I have the same problem with you and I want code that is shorter, easy to use with json, and more maintainable in my codebase and production system.
Updated.. I solved this issue by stating the charset on PDO connection as below:
"mysql:host=$host;dbname=$db;charset=utf8"
All data received was then in the correct charset for the rest of the code to use
This warning comes because your dataframe x
is a copy of a slice. This is not easy to know why, but it has something to do with how you have come to the current state of it.
You can either create a proper dataframe
out of x by doing
x = x.copy()
This will remove the warning, but it is not the proper way
You should be using the DataFrame.loc
method, as the warning suggests, like this:
x.loc[:,'Mass32s'] = pandas.rolling_mean(x.Mass32, 5).shift(-2)
After tried all above, still can't resolved my issue yet. But got new solution for my problem.
At server where you are going to make a request, there should be a entry of your virtual host.
sudo vim /etc/hosts
and insert
192.xxx.x.xx www.domain.com
The reason if you are making request from server to itself then, to resolve your virtual host or to identify it, server would need above stuff, otherwise server won't understand your requesting(origin) host.
In my view, dates and times should be handled as two separate input boxes for it to be most usable and efficient for the user to input. Let the user input one thing at a time is a good principle, imho.
I use the core UI DatePicker, and the following time picker.
This one is inspired by the one Google Calendar uses:
jQuery timePicker:
examples: http://labs.perifer.se/timedatepicker/
project on github: https://github.com/perifer/timePicker
I found it to be the best among all of the alternatives. User can input fast, it looks clean, is simple, and allows user to input specific times down to the minute.
PS: In my view: sliders (used by some alternative time pickers) take too many clicks and require mouse precision from the user (which makes input slower).
I also got a requirement to calculate the process time of some code lines. So I tried the approved answer and I got this warning.
DeprecationWarning: time.clock has been deprecated in Python 3.3 and will be removed from Python 3.8: use time.perf_counter or time.process_time instead
So python will remove time.clock() from Python 3.8. You can see more about it from issue #13270. This warning suggest two function instead of time.clock(). In the documentation also mention about this warning in-detail in time.clock() section.
Deprecated since version 3.3, will be removed in version 3.8: The behaviour of this function depends on the platform: use perf_counter() or process_time() instead, depending on your requirements, to have a well defined behaviour.
Let's look at in-detail both functions.
Return the value (in fractional seconds) of a performance counter, i.e. a clock with the highest available resolution to measure a short duration. It does include time elapsed during sleep and is system-wide. The reference point of the returned value is undefined, so that only the difference between the results of consecutive calls is valid.
New in version 3.3.
So if you want it as nanoseconds
, you can use time.perf_counter_ns() and if your code consist with time.sleep(secs), it will also count. Ex:-
import time
def func(x):
time.sleep(5)
return x * x
lst = [1, 2, 3]
tic = time.perf_counter()
print([func(x) for x in lst])
toc = time.perf_counter()
print(toc - tic)
# [1, 4, 9]
# 15.0041916 --> output including 5 seconds sleep time
Return the value (in fractional seconds) of the sum of the system and user CPU time of the current process. It does not include time elapsed during sleep. It is process-wide by definition. The reference point of the returned value is undefined, so that only the difference between the results of consecutive calls is valid.
New in version 3.3.
So if you want it as nanoseconds
, you can use time.process_time_ns() and if your code consist with time.sleep(secs), it won't count. Ex:-
import time
def func(x):
time.sleep(5)
return x * x
lst = [1, 2, 3]
tic = time.process_time()
print([func(x) for x in lst])
toc = time.process_time()
print(toc - tic)
# [1, 4, 9]
# 0.0 --> output excluding 5 seconds sleep time
Please note both time.perf_counter_ns() and time.process_time_ns() come up with Python 3.7 onward.
Deleting all your migrations in the migration folder of your django app, then run makemigrations followed by migrate commands. You should be able to get out of the woods.
Try following steps:
ipconfig
(or ifconfig
on Linux) at command prompt. This will give you the IP address of your own machine. For example, your machine's IP address is 192.168.1.6. So your broadcast IP address is 192.168.1.255.ping 192.168.1.255
(may require -b
on Linux)arp -a
. You will get the list of all IP addresses on your segment.If each file only has one sequence of aminoacids, I wouldn't use regular expressions at all. Just something like this:
def read_amino_acid_sequence(path):
with open(path) as sequence_file:
title = sequence_file.readline() # read 1st line
aminoacid_sequence = sequence_file.read() # read the rest
# some cleanup, if necessary
title = title.strip() # remove trailing white spaces and newline
aminoacid_sequence = aminoacid_sequence.replace(" ","").replace("\n","")
return title, aminoacid_sequence
onProgressChanged() should be called on every progress changed, not just on first and last touch (that why you have onStartTrackingTouch() and onStopTrackingTouch() methods).
Make sure that your SeekBar have more than 1 value, that is to say your MAX>=3.
In your onCreate:
yourSeekBar=(SeekBar) findViewById(R.id.yourSeekBar);
yourSeekBar.setOnSeekBarChangeListener(new yourListener());
Your listener:
private class yourListener implements SeekBar.OnSeekBarChangeListener {
public void onProgressChanged(SeekBar seekBar, int progress,
boolean fromUser) {
// Log the progress
Log.d("DEBUG", "Progress is: "+progress);
//set textView's text
yourTextView.setText(""+progress);
}
public void onStartTrackingTouch(SeekBar seekBar) {}
public void onStopTrackingTouch(SeekBar seekBar) {}
}
Please share some code and the Log results for furter help.
It seemed quite hard to find this information, but eventually, I came across this question
You have to look at the 'System' event log, and filter by the WAS source.
Here is more info about the WAS (Windows Process Activation Service)
Quick and dirt alternative solution. You can use a tabulation character along with preformatted text. Here's a possibility:
<style type="text/css">
ol {
list-style-position: inside;
}
li:first-letter {
white-space: pre;
}
</style>
and your html:
<ol>
<li> an item</li>
<li> another item</li>
...
</ol>
Note that the space between the li
tag and the beggining of the text is a tabulation character (what you get when you press the tab key inside notepad).
If you need to support older browsers, you can do this instead:
<style type="text/css">
ol {
list-style-position: inside;
}
</style>
<ol>
<li><pre> </pre>an item</li>
<li><pre> </pre>another item</li>
...
</ol>
with more simple regex
Here it is :
var regexEmail = /\w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*/;
var email = document.getElementById("txtEmail");
if (regexEmail.test(email.value)) {
alert("It's Okay")
} else {
alert("Not Okay")
}
good luck.
SELECT
*
FROM
[SERVER2NAME].[THEDB].[THEOWNER].[THETABLE]
You can also look at using Linked Servers. Linked servers can be other types of data sources too such as DB2 platforms. This is one method for trying to access DB2 from a SQL Server TSQL or Sproc call...
<form name="add" method="post">
<p>Age:</p>
<select name="age">
<option value="1_sre">23</option>
<option value="2_sam">24</option>
<option value="5_john">25</option>
</select>
<input type="submit" name="submit"/>
</form>
You will have the selected value in $_POST['age']
, e.g. 1_sre
. Then you will be able to split the value and get the 'stud_name'
.
$stud = explode("_",$_POST['age']);
$stud_id = $stud[0];
$stud_name = $stud[1];
In 2020, just do
$.datetimepicker.setLocale('en');
Of course, replace 'en' with the correct language ('sv', 'fr', ...)
Check this PowerShell Which.
The code provided there suggests this:
($Env:Path).Split(";") | Get-ChildItem -filter notepad.exe
PostgreSQL Autodoc has worked well for me. It is a simple command line tool. From the web page:
This is a utility which will run through PostgreSQL system tables and returns HTML, Dot, Dia and DocBook XML which describes the database.
Regarding @Cherian's answer, the following lines can be removed:
SET @OLD_SQL_MODE=@@SQL_MODE, SQL_MODE='ANSI';
...
SET SQL_MODE=@OLD_SQL_MODE;
...
This was a bug pre 5.1.23. After that version these are no longer required. So, for copy/paste convenience, here is the same with the above lines removed. Again, for example purposes "test" is the user and "databaseName" is the database; and this was from this bug.
DROP PROCEDURE IF EXISTS databaseName.drop_user_if_exists ;
DELIMITER $$
CREATE PROCEDURE databaseName.drop_user_if_exists()
BEGIN
DECLARE foo BIGINT DEFAULT 0 ;
SELECT COUNT(*)
INTO foo
FROM mysql.user
WHERE User = 'test' and Host = 'localhost';
IF foo > 0 THEN
DROP USER 'test'@'localhost' ;
END IF;
END ;$$
DELIMITER ;
CALL databaseName.drop_user_if_exists() ;
DROP PROCEDURE IF EXISTS databaseName.drop_users_if_exists ;
CREATE USER 'test'@'localhost' IDENTIFIED BY 'a';
GRANT ALL PRIVILEGES ON databaseName.* TO 'test'@'localhost'
WITH GRANT OPTION
Somebody posted this code, which has the problem of not retaining the scroll position when restored. The reason is that people tend to apply it to html and body or just the body but it should be applied to html only. This way when restored the scroll position will be kept:
$('html').css({
'overflow': 'hidden',
'height': '100%'
});
To restore:
$('html').css({
'overflow': 'auto',
'height': 'auto'
});
I use this:
function parseJsonDate(jsonDateString){
return new Date(parseInt(jsonDateString.replace('/Date(', '')));
}
Update 2018:
This is an old question. Instead of still using this old non standard serialization format I would recommend to modify the server code to return better format for date. Either an ISO string containing time zone information, or only the milliseconds. If you use only the milliseconds for transport it should be UTC
on server and client.
2018-07-31T11:56:48Z
- ISO string can be parsed using new Date("2018-07-31T11:56:48Z")
and obtained from a Date
object
using dateObject.toISOString()
1533038208000
- milliseconds since midnight January 1, 1970, UTC - can be parsed using new Date(1533038208000) and obtained from a Date
object
using dateObject.getTime()
This will work fine with Linq to Objects. However, some LINQ providers have difficulty running CLR methods as part of the query. This is expecially true of some database providers.
The problem is that the DB providers try to move and compile the LINQ query as a database query, to prevent pulling all of the objects across the wire. This is a good thing, but does occasionally restrict the flexibility in your predicates.
Unfortunately, without checking the provider documentation, it's difficult to always know exactly what will or will not be supported directly in the provider. It looks like your provider allows comparisons, but not the string check. I'd guess that, in your case, this is probably about as good of an approach as you can get. (It's really not that different from the IsNullOrEmpty check, other than creating the "string.Empty" instance for comparison, but that's minor.)
An update to @Brandon's answer, generalized to a method
- (NSString*) postToUrl:(NSString*)urlString data:(NSData*)dataToSend withFilename:(NSString*)filename
{
NSMutableURLRequest *request= [[NSMutableURLRequest alloc] init];
[request setURL:[NSURL URLWithString:urlString]];
[request setHTTPMethod:@"POST"];
NSString *boundary = @"---------------------------14737809831466499882746641449";
NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@", boundary];
[request addValue:contentType forHTTPHeaderField: @"Content-Type"];
NSMutableData *postbody = [NSMutableData data];
[postbody appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[postbody appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"userfile\"; filename=\"%@\"\r\n", filename] dataUsingEncoding:NSUTF8StringEncoding]];
[postbody appendData:[@"Content-Type: application/octet-stream\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
[postbody appendData:[NSData dataWithData:dataToSend]];
[postbody appendData:[[NSString stringWithFormat:@"\r\n--%@--\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[request setHTTPBody:postbody];
NSError* error;
NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:&error];
if (returnData) {
return [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding];
}
else {
return nil;
}
}
Invoke like so, sending data from a string:
[self postToUrl:@"<#Your url string#>"
data:[@"<#Your string to send#>" dataUsingEncoding:NSUTF8StringEncoding]
withFilename:@"<#Filename to post with#>"];
In HTML, the selected option is represented by the presence of the selected
attribute on the <option>
element like so:
<option ... selected>...</option>
Or if you're HTML/XHTML strict:
<option ... selected="selected">...</option>
Thus, you just have to let JSP/EL print it conditionally. Provided that you've prepared the selected department as follows:
request.setAttribute("selectedDept", selectedDept);
then this should do:
<select name="department">
<c:forEach var="item" items="${dept}">
<option value="${item.key}" ${item.key == selectedDept ? 'selected="selected"' : ''}>${item.value}</option>
</c:forEach>
</select>
If you just want to remove untracked files, do this:
git clean -df
add x
to that if you want to also include specifically ignored files. I use git clean -dfx
a lot throughout the day.
You can create custom git by just writing a script called git-whatever
and having it in your path.
Or this:
f(x)=\begin{cases}
0, & -\pi\leqslant x <0\\
\pi, & 0 \leqslant x \leqslant +\pi
\end{cases}
Here's the quick and dirty way.
// Add $injector as a parameter for your controller
function myAngularController($scope,$injector){
$scope.sendorders = function(){
// now you can use $injector to get the
// handle of $rootScope and broadcast to all
$injector.get('$rootScope').$broadcast('sinkallships');
};
}
Here is an example function to add within any of the sibling controllers:
$scope.$on('sinkallships', function() {
alert('Sink that ship!');
});
and of course here's your HTML:
<button ngclick="sendorders()">Sink Enemy Ships</button>
I found this to be the best way of doing this (I had an issue with my server not letting me delete).
On the server that hosts the origin
repository, type the following from a directory inside the repository:
git config receive.denyDeleteCurrent ignore
On your workstation:
git branch -m master vabandoned # Rename master on local
git branch -m newBranch master # Locally rename branch newBranch to master
git push origin :master # Delete the remote's master
git push origin master:refs/heads/master # Push the new master to the remote
git push origin abandoned:refs/heads/abandoned # Push the old master to the remote
Back on the server that hosts the origin
repository:
git config receive.denyDeleteCurrent true

REPLACE INTO
pros:
cons:
too slow.
auto-increment key will CHANGE(increase by 1) if there is entry matches unique key
or primary key
, because it deletes the old entry then insert new one.
INSERT IGNORE
pros:
cons:
auto-increment key will not change if there is entry matches unique key
or primary key
but auto-increment index will increase by 1
some other errors/warnings will be ignored such as data conversion error.
INSERT ... ON DUPLICATE KEY UPDATE
pros:
cons:
looks relatively complex if you just want to insert not update.
auto-increment key will not change if there is entry matches unique key
or primary key
but auto-increment index will increase by 1
unique key
or primary key
?As mentioned in the comment below by @toien: "auto-increment column will be effected depends on innodb_autoinc_lock_mode
config after version 5.1" if you are using innodb
as your engine, but this also effects concurrency, so it needs to be well considered before used. So far I'm not seeing any better solution.
I tried the options in the existing answers, mainly the one marked correct which did not work in my scenario. However, what did work was using phpMyAdmin. Select the database and then select the table, from the bottom drop down menu select "Repair table".
there is a quite near solution (do not fix all Paste ways) but most of them:
It works for inputs as well as for textareas:
<input type="text" ... >
<textarea ... >...</textarea>
Do like this:
<input type="text" ... onkeyup="JavaScript: ControlChanges()" onmouseup="JavaScript: ControlChanges()" >
<textarea ... onkeyup="JavaScript: ControlChanges()" onmouseup="JavaScript: ControlChanges()" >...</textarea>
As i said, not all ways to Paste fire an event on all browsers... worst some do not fire any event at all, but Timers are horrible to be used for such.
But most of Paste ways are done with keyboard and/or mouse, so normally an onkeyup or onmouseup are fired after a paste, also onkeyup is fired when typing on keyboard.
Ensure yor check code does not take much time... otherwise user get a poor impresion.
Yes, the trick is to fire on key and on mouse... but beware both can be fired, so take in mind such!!!
for wamp server use 10.0.2.2
for local host
e.g. 10.0.2.2/phpMyAdmin
and for tomcat use 10.0.2.2:8080/server
It indicates the absence of a return value in a function.
Some languages have two sorts of subroutines: procedures and functions. Procedures are just a sequence of operations, whereas a function is a sequence of operations that return a result.
In C and its derivatives, the difference between the two is not explicit. Everything is basically a function. the void
keyword indicates that it's not an "actual" function, since it doesn't return a value.
There is no standard naming of keys in JSON. According to the Objects section of the spec:
The JSON syntax does not impose any restrictions on the strings used as names,...
Which means camelCase or snake_case should work fine.
Imposing a JSON naming convention is very confusing. However, this can easily be figured out if you break it down into components.
Programming language for generating JSON
JSON itself has no standard naming of keys
Programming language for parsing JSON
snake_case will still make sense for those with Java entries because the existing JSON libraries for Java are using only methods to access the keys instead of using the standard dot.syntax. This means that it wouldn't hurt that much for Java to access the snake_cased keys in comparison to the other programming language which can do the dot.syntax.
Example for Java's org.json
package
JsonObject.getString("snake_cased_key")
Example for Java's com.google.gson
package
JsonElement.getAsString("snake_cased_key")
Choosing the right JSON naming convention for your JSON implementation depends on your technology stack. There are cases where one can use snake_case, camelCase, or any other naming convention.
Another thing to consider is the weight to be put on the JSON-generator vs the JSON-parser and/or the front-end JavaScript. In general, more weight should be put on the JSON-generator side rather than the JSON-parser side. This is because business logic usually resides on the JSON-generator side.
Also, if the JSON-parser side is unknown then you can declare what ever can work for you.
Say you want to save the string I'm a "foobar"
in the database.
Your query will look something like INSERT INTO foos (text) VALUES ("$text")
.
With the $text
variable replaced, this will look like this:
INSERT INTO foos (text) VALUES ("I'm a "foobar"")
Now, where exactly does the string end? You may know, an SQL parser doesn't. Not only will this simply break this query, it can also be abused to inject SQL commands you didn't intend.
mysql_real_escape_string
makes sure such ambiguities do not occur by escaping characters which have special meaning to an SQL parser:
mysql_real_escape_string($text) => I\'m a \"foobar\"
This becomes:
INSERT INTO foos (text) VALUES ("I\'m a \"foobar\"")
This makes the statement unambiguous and safe. The \
signals that the following character is not to be taken by its special meaning as string terminator. There are a few such characters that mysql_real_escape_string
takes care of.
Escaping is a pretty universal thing in programming languages BTW, all along the same lines. If you want to type the above sentence literally in PHP, you need to escape it as well for the same reasons:
$text = 'I\'m a "foobar"';
// or
$text = "I'm a \"foobar\"";
This is because your row variable/tuple does not contain any value for that index. You can try printing the whole list like print(row)
and check how many indexes there exists.
PHP offical Manual : end()
Parameters
array
The array. This array is passed by reference because it is modified by the function. This means you must pass it a real variable and not a function returning an array because only actual variables may be passed by reference.
Depending on why you are doing this, using a std::set might be a better idea than std::vector.
It allows each element to occur only once. If you add it multiple times, there will only be one instance to erase anyway. This will make the erase operation trivial. The erase operation will also have lower time complexity than on the vector, however, adding elements is slower on the set so it might not be much of an advantage.
This of course won't work if you are interested in how many times an element has been added to your vector or the order the elements were added.
As Jake points out, TARGET_IPHONE_SIMULATOR
is a subset of TARGET_OS_IPHONE
.
Also, TARGET_OS_IPHONE
is a subset of TARGET_OS_MAC
.
So a better approach might be:
#ifdef _WIN64
//define something for Windows (64-bit)
#elif _WIN32
//define something for Windows (32-bit)
#elif __APPLE__
#include "TargetConditionals.h"
#if TARGET_OS_IPHONE && TARGET_IPHONE_SIMULATOR
// define something for simulator
#elif TARGET_OS_IPHONE
// define something for iphone
#else
#define TARGET_OS_OSX 1
// define something for OSX
#endif
#elif __linux
// linux
#elif __unix // all unices not caught above
// Unix
#elif __posix
// POSIX
#endif
JAR files allow to package multiple files in order to use it as a library, plugin, or any kind of application. On the other hand, WAR files are used only for web applications.
JAR can be created with any desired structure. In contrast, WAR has a predefined structure with WEB-INF and META-INF directories.
A JAR file allows Java Runtime Environment (JRE) to deploy an entire application including the classes and the associated resources in a single request. On the other hand, a WAR file allows testing and deploying a web application easily.
This is a very simple to create file in git bash at first write touch then file name with extension
for example
touch filename.extension
Here you can find some public REST services for encryption and security related things: http://security.jelastic.servint.net
you should check the active Working Set - make sure it is off.
How about if you use grep instead of find?
ls | grep .txt$ > out.txt
Now you can read this file and the filenames are in the form of a list.
In the hexadecimal it can't get a negative value. So it shows it like ffffffff.
The advantage to using the unsigned version (when you know the values contained will be non-negative) is that sometimes the computer will spot errors for you (the program will "crash" when a negative value is assigned to the variable).
Inside try
block we write codes that can throw an exception.
The catch
block is where we handle the exception.
The finally
block is always executed no matter whether exception occurs or not.
Now if we have try-finally block instead of try-catch-finally block then the exception will not be handled and after the try block instead of control going to catch block it will go to finally block. We can use try-finally block when we want to do nothing with the exception.
If you don't mind using lodash try out https://github.com/rockabox/ng-lodash it wraps lodash completely so it is the only dependency and you don't need to load any other script files such as lodash.
Lodash is completely off of the window scope and no "hoping" that it's been loaded prior to your module.
You could use IsEmpty()
function like this:
...
Set rRng = Sheet1.Range("A10")
If IsEmpty(rRng.Value) Then ...
you could also use following:
If ActiveCell.Value = vbNullString Then ...
Please consider using some code like this:
SqlDataReader reader = command.ExecuteReader();
int numRows = 0;
DataTable dt = new DataTable();
dt.Load(reader);
numRows = dt.Rows.Count;
string attended_type = "";
for (int index = 0; index < numRows; index++)
{
attended_type = dt.Rows[indice2]["columnname"].ToString();
}
reader.Close();
I asked a question that kinda duplicated on this topic a while back, and after excessive research, and seeing a lot of information missing that should be here, I feel I have something valuable to add to this older post.
let properyValue = element.style['enter-a-property'];
however I rarely go this route because it doesn't work on property values assigned via style-sheets. To give you an example, I'll demonstrate with a bit of pseudo code.
let elem = document.getElementById('someDiv');
let cssProp = elem.style['width'];
Using the code example above; if the width property of the div element that was stored in the 'elem' variable was styled in a CSS style-sheet, and not styled inside of its HTML tag, you are without a doubt going to get a return value of undefined stored inside of the cssProp variable. The undefined value occurs because in-order to get the correct value, the code written inside a CSS Style-Sheet needs to be computed in-order to get the value, therefore; you must use a method that will compute the value of the property who's value lies within the style-sheet.
function getCssProp(){
let ele = document.getElementById("test");
let cssProp = window.getComputedStyle(ele,null).getPropertyValue("width");
}
W3Schools getComputedValue Doc This gives a good example, and lets you play with it, however, this link Mozilla CSS getComputedValue doc talks about the getComputedValue function in detail, and should be read by any aspiring developer who isn't totally clear on this subject.
$(selector).css(property,value)
...does get, and does set. It is what I use, the only downside is you got to know JQuery, but this is honestly one of the very many good reasons that every Javascript Developer should learn JQuery, it just makes life easy, and offers methods, like this one, which is not available with standard Javascript. Hope this helps someone!!!
Or, if you're customizing the dialog using a theme defined in your style xml, put this line in your theme:
<item name="android:windowCloseOnTouchOutside">true</item>

I had the same problem. I'm no expert but this is the solution we used: Before you filter your data, first create a temporary column to populate your entire data set with your original sort order. Auto number the temporary "original sort order" column. Now filter your data. Copy and paste the filtered data into a new worksheet. This will move only the filtered data to the new sheet so that your row numbers will become consecutive. Now auto number your desired field. Go back to your original worksheet and delete the filtered rows. Copy and paste the newly numbered data from the secondary sheet onto the bottom of your original worksheet. Then clear your filter and sort the worksheet by the temporary "original sort order" column. This will put your newly numbered data back into its original order and you can then delete the temporary column.
Destination Host Unreachable
This message indicates one of two problems: either the local system has no route to the desired destination, or a remote router reports that it has no route to the destination.
If the message is simply "Destination Host Unreachable," then there is no route from the local system, and the packets to be sent were never put on the wire.
If the message is "Reply From < IP address >: Destination Host Unreachable," then the routing problem occurred at a remote router, whose address is indicated by the "< IP address >" field.
Request Timed Out
This message indicates that no Echo Reply messages were received within the default time of 1 second. This can be due to many different causes; the most common include network congestion, failure of the ARP request, packet filtering, routing error, or a silent discard.

Yes you can have multiple expression to add multiple class in ng-class.
For example:
<div ng-class="{class1:Result.length==2,class2:Result.length==3}"> Dummy Data </div>
Just convert the string to uppercase or to lower case to match the search criteria, i.e:
string title = "ASTRINGTOTEST"; title.ToLower().Contains("string");
create table my_table (
id_part1 int not null,
id_part2 int not null,
primary key (id_part1, id_part2)
)
Do C-b
, :show
which will show you all your current settings. /green
, nnn
will find you which properties have been set to green, the default. Do C-b
, :set window-status-bg cyan
and the bottom bar should change colour.
List available colours for tmux
You can tell more easily by the titles and the colours as they're actually set in your live session :show
, than by searching through the man
page, in my opinion. It is a very well-written man
page when you have the time though.
If you don't like one of your changes and you can't remember how it was originally set, you can open do a new tmux session. To change settings for good edit ~/.tmux.conf
with a line like set window-status-bg -g cyan
. Here's mine: https://gist.github.com/9083598
import os, os.path
To get (full-path) immediate sub-directories in a directory:
def SubDirPath (d):
return filter(os.path.isdir, [os.path.join(d,f) for f in os.listdir(d)])
To get the latest (newest) sub-directory:
def LatestDirectory (d):
return max(SubDirPath(d), key=os.path.getmtime)
Press the start button. In the search box type "cmd", then press Ctrl+Shift+Enter
You can use theme_get()
to display the possible options for theme.
You can control the legend font size using:
+ theme(legend.text=element_text(size=X))
replacing X with the desired size.
In all of the cases above, the variable is correctly set, but not correctly read! The right way is to use double quotes when referencing:
echo "$var"
This gives the expected value in all the examples given. Always quote variable references!
Why?
When a variable is unquoted, it will:
Undergo field splitting where the value is split into multiple words on whitespace (by default):
Before: /* Foobar is free software */
After: /*
, Foobar
, is
, free
, software
, */
Each of these words will undergo pathname expansion, where patterns are expanded into matching files:
Before: /*
After: /bin
, /boot
, /dev
, /etc
, /home
, ...
Finally, all the arguments are passed to echo, which writes them out separated by single spaces, giving
/bin /boot /dev /etc /home Foobar is free software Desktop/ Downloads/
instead of the variable's value.
When the variable is quoted it will:
This is why you should always quote all variable references, unless you specifically require word splitting and pathname expansion. Tools like shellcheck are there to help, and will warn about missing quotes in all the cases above.
There is a general way of converting recursive traversal to iterator by using a lazy iterator which concatenates multiple iterator suppliers (lambda expression which returns an iterator). See my Converting Recursive Traversal to Iterator.
Use :
<EditText
..
android:drawableStart="@drawable/icon" />
here is a jQuery plugin I came up with:
$.fn.cycle = function(timeout){
var $all_elem = $(this)
show_cycle_elem = function(index){
if(index == $all_elem.length) return; //you can make it start-over, if you want
$all_elem.hide().eq(index).fadeIn()
setTimeout(function(){show_cycle_elem(++index)}, timeout);
}
show_cycle_elem(0);
}
You need to have a common classname for all the divs you wan to cycle, use it like this:
$("div.cycleme").cycle(5000)
Plot twist!
You can have orphaned distributed transactions holding exclusive locks and you will not see them if your script assumes there is a session associated with the transaction (there isn't!). Run the script below to identify these transactions:
;WITH ORPHANED_TRAN AS (
SELECT
dat.name,
dat.transaction_uow,
ddt.database_transaction_begin_time,
ddt.database_transaction_log_bytes_reserved,
ddt.database_transaction_log_bytes_used
FROM
sys.dm_tran_database_transactions ddt,
sys.dm_tran_active_transactions dat,
sys.dm_tran_locks dtl
WHERE
ddt.transaction_id = dat.transaction_id AND
dat.transaction_id = dtl.request_owner_id AND
dtl.request_session_id = -2 AND
dtl.request_mode = 'X'
)
SELECT DISTINCT * FROM ORPHANED_TRAN
Once you have identified the transaction, use the transaction_uow column to find it in MSDTC and decide whether to abort or commit it. If the transaction is marked as In Doubt (with a question mark next to it) you will probably want to abort it.
You can also kill the Unit Of Work (UOW) by specifying the transaction_uow in the KILL command:
KILL '<transaction_uow>'

As suggested here you can also inject the HttpServletRequest
as a method param, e.g.:
public MyResponseObject myApiMethod(HttpServletRequest request, ...) {

-> d
-> p
As @Houcem Berrayana say
If you would like to use n>24
then you can use the code like:
Date dateBefore = new Date((d.getTime() - n * 24 * 3600 * 1000) - n * 24 * 3600 * 1000);
Suppose you want to find last 30 days date, then you'd use:
Date dateBefore = new Date((d.getTime() - 24 * 24 * 3600 * 1000) - 6 * 24 * 3600 * 1000);
In python, it's called slicing. Here is an example of python's slice notation:
>>> list1 = ['a','b','c','d','e','f','g','h', 'i', 'j', 'k', 'l']
>>> print list1[:5]
['a', 'b', 'c', 'd', 'e']
>>> print list1[-7:]
['f', 'g', 'h', 'i', 'j', 'k', 'l']
Note how you can slice either positively or negatively. When you use a negative number, it means we slice from right to left.
A WSDL (Web Service Definition Language) is a meta-data file that describes the web service.
Things like operation name, parameters etc.
The soap messages are the actual payloads
You can format containers as well as ranges and tuples using the {fmt} library. For example:
#include <vector>
#include <fmt/ranges.h>
int main() {
std::vector<char> path;
for (int c = 'a'; c <= 'z'; ++c)
path.push_back(c);
fmt::print("{}", path);
}
prints
{'a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p', 'q', 'r', 's', 't', 'u', 'v', 'w', 'x', 'y', 'z'}
to stdout
(godbolt).
Alternatively you can iterate over the elements and print them individually.
Disclaimer: I'm the author of {fmt}.

Basically you need to download the IEDriverServer.exe from Selenium HQ website without executing anything just remmeber the location where you want it and then put the code on Eclipse like this
System.setProperty("webdriver.ie.driver", "C:\\Users\\juan.torres\\Desktop\\QA stuff\\IEDriverServer_Win32_2.32.3\\IEDriverServer.exe");
WebDriver driver= new InternetExplorerDriver();
driver.navigate().to("http://www.youtube.com/");
for the path use double slash //
ok have fun !!
To generalize the good answer of Mike Nakis with String.CASE_INSENSITIVE_ORDER

While all the suggestions above are working, sometimes I need to have an empty selection (showing placeholder text) when initially enter my screen. So, to prevent select box from adding this empty selection at the beginning (or sometimes at the end) of my list I am using this trick:
<div ng-app="MyApp1">
<div ng-controller="MyController">
<input type="text" ng-model="feed.name" placeholder="Name" />
<select ng-model="feed.config" ng-options="template.value as template.name for template in feed.configs" placeholder="Config">
<option value="" selected hidden />
</select>
</div>
</div>
Now you have defined this empty option, so select box is happy, but you keep it hidden.
FAT32
along with FAT16
and FAT12
are File System Types, but vfat
along with umsdos
and msdos
are drivers, used to mount the FAT file systems in Linux. The choosing of the driver determines how some of the features are applied to the file system, for example, systems mounted with msdos
driver don't have long filenames (they are 8.3 format). vfat
is the most common driver for mounting FAT32 file systems nowadays.
Source: this wikipedia article
Output of commands like df
and lsblk
indeed show vfat
as the File System Type. But sudo file -sL /dev/<partition>
shows FAT (32 bit)
if a File System is FAT32.
You can confirm vfat
is a module and not a File System Type by running modinfo vfat
.
Your server is imposing some resource limit that your site is hitting. This is usually RAM, CPU, or INODES.
Ask your server administrator what the limits are and what it is you are hitting to solve.
The following bit of code does what you ask for. Just make sure that you assign enough space so that the text on the button becomes visible
JFrame frame = new JFrame("test");
frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
JPanel panel = new JPanel(new GridLayout(4,4,4,4));
for(int i=0 ; i<16 ; i++){
JButton btn = new JButton(String.valueOf(i));
btn.setPreferredSize(new Dimension(40, 40));
panel.add(btn);
}
frame.setContentPane(panel);
frame.pack();
frame.setVisible(true);
The X and Y (two first parameters of the GridLayout constructor) specify the number of rows and columns in the grid (respectively). You may leave one of them as 0 if you want that value to be unbounded.
Edit
I've modified the provided code and I believe it now conforms to what is desired:
JFrame frame = new JFrame("Colored Trails");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JPanel mainPanel = new JPanel();
mainPanel.setLayout(new BoxLayout(mainPanel, BoxLayout.Y_AXIS));
JPanel firstPanel = new JPanel();
firstPanel.setLayout(new GridLayout(4, 4));
firstPanel.setMaximumSize(new Dimension(400, 400));
JButton btn;
for (int i=1; i<=4; i++) {
for (int j=1; j<=4; j++) {
btn = new JButton();
btn.setPreferredSize(new Dimension(100, 100));
firstPanel.add(btn);
}
}
JPanel secondPanel = new JPanel();
secondPanel.setLayout(new GridLayout(5, 13));
secondPanel.setMaximumSize(new Dimension(520, 200));
for (int i=1; i<=5; i++) {
for (int j=1; j<=13; j++) {
btn = new JButton();
btn.setPreferredSize(new Dimension(40, 40));
secondPanel.add(btn);
}
}
mainPanel.add(firstPanel);
mainPanel.add(secondPanel);
frame.setContentPane(mainPanel);
frame.setSize(520,600);
frame.setMinimumSize(new Dimension(520,600));
frame.setVisible(true);
Basically I now set the preferred size of the panels and a minimum size for the frame.
There are a number of dictionary files available online - if you're on linux, a lot of (all?) distros come with an /etc/dictionaries-common/words file, which you can easily parse (words = open('/etc/dictionaries-common/words').readlines()
, eg) for use.

So I figured out what is wrong with this statement:
Import-Csv H:\Programs\scripts\SomeText.csv |`
(Original)
Import-Csv H:\Programs\scripts\SomeText.csv -Delimiter "|"
(Proposed, You must use quotations; otherwise, it will not work and ISE will give you an error)
It requires the -Delimiter "|"
, in order for the variable to be populated with an array of items. Otherwise, Powershell ISE does not display the list of items.
I cannot say that I would recommend the |
operator, since it is used to pipe cmdlets into one another.
I still cannot get the if statement to return true and output the values entered via the prompt.
If anyone else can help, it would be great. I still appreciate the post, it has been very helpful!
std::list
does not provide a search method. You can iterate over the list and check if the element exists or use std::find
. But I think for your situation std::set
is more preferable. The former will take O(n)
time but later will take O(lg(n))
time to search.
You can simply use:
int my_var = 3;
std::set<int> mySet {1, 2, 3, 4};
if(mySet.find(myVar) != mySet.end()){
//do whatever
}
You are repeating the y,m,d
.
Instead of
gmdate('yyyy-mm-dd hh:mm:ss \G\M\T', time());
You should use it like
gmdate('Y-m-d h:m:s \G\M\T', time());
(apply on Mac, and probably other Unixes)
Actually there is a problem with the wc approach: it does not count the last line if it does not terminate with the end of line symbol.
Use this instead
nbLines=$(cat -n file.txt | tail -n 1 | cut -f1 | xargs)
or even better (thanks gniourf_gniourf):
nblines=$(grep -c '' file.txt)
Note: The awk approach by chilicuil also works.
