You just need to:
Step 1: Go home directory of C:\ with typing cd.. (2 times)
Step 2: It appears now C:\>
Step 3: Type dir Windows\System32\run
That's all, it shows complete files & folder details inside target folder.
Details: I used Windows\System32\com
folder as example, you should type your own folder name etc. Windows\System32\run
I believe the intent was to rename System32, but so many applications hard-coded for that path, that it wasn't feasible to remove it.
SysWoW64 wasn't intended for the dlls of 64-bit systems, it's actually something like "Windows on Windows64", meaning the bits you need to run 32bit apps on a 64bit windows.
This article explains a bit:
"Windows x64 has a directory System32 that contains 64-bit DLLs (sic!). Thus native processes with a bitness of 64 find “their” DLLs where they expect them: in the System32 folder. A second directory, SysWOW64, contains the 32-bit DLLs. The file system redirector does the magic of hiding the real System32 directory for 32-bit processes and showing SysWOW64 under the name of System32."
Edit: If you're talking about an installer, you really should not hard-code the path to the system folder. Instead, let Windows take care of it for you based on whether or not your installer is running on the emulation layer.
In my case AutoMapper works well.
AutoMapper can map to/from dynamic objects without any explicit configuration:
public class Foo {
public int Bar { get; set; }
public int Baz { get; set; }
}
dynamic foo = new MyDynamicObject();
foo.Bar = 5;
foo.Baz = 6;
Mapper.Initialize(cfg => {});
var result = Mapper.Map<Foo>(foo);
result.Bar.ShouldEqual(5);
result.Baz.ShouldEqual(6);
dynamic foo2 = Mapper.Map<MyDynamicObject>(result);
foo2.Bar.ShouldEqual(5);
foo2.Baz.ShouldEqual(6);
Similarly you can map straight from dictionaries to objects, AutoMapper will line up the keys with property names.
more info https://github.com/AutoMapper/AutoMapper/wiki/Dynamic-and-ExpandoObject-Mapping
I think it should be
verify(mockBar, times(2)).doSomething(...)
Sample from mockito javadoc:
ArgumentCaptor<Person> peopleCaptor = ArgumentCaptor.forClass(Person.class);
verify(mock, times(2)).doSomething(peopleCaptor.capture());
List<Person> capturedPeople = peopleCaptor.getAllValues();
assertEquals("John", capturedPeople.get(0).getName());
assertEquals("Jane", capturedPeople.get(1).getName());
If you are using Auto Layout then you can do it on the Story board.
Add a height constraint to the text field, then change the height constraint constant to any desired value. Steps are shown below:
Step 1: Create a height constraint for the text field
Step 2: Select Height Constraint
Step 3: Change Height Constraint's constant value
The normal method to send a file upload is POST, thus also post_max_size
should be 16 Mb or more.
Incidentally, also memory_limit
plays a role. It should be bigger than 16Mb, but since the default value is 128Mb, you won't see this problem. Example php.ini
configuration:
post_max_size = 16M
upload_max_filesize = 16M
memory_limit = 128M
Change these value in php.ini
if you've access to it, otherwise you can try to change them in an .htaccess
file.
php_value upload_max_filesize 16M
php_value post_max_size 16M
This will work only if the AllowOverride
settings permit it. Otherwise, you've to ask to your hosting company.
EDIT: this is a very old answer. SHA1 was deprecated in 2011 and has now been broken in practice. https://shattered.io/ Use a newer standard instead (e.g. SHA256, SHA512, etc).
If your answer to the question in my comment is "No", here's what I use:
public static byte[] HashPassword(string password)
{
var provider = new SHA1CryptoServiceProvider();
var encoding = new UnicodeEncoding();
return provider.ComputeHash(encoding.GetBytes(password));
}
Placing a $
in front of the row value to keep constant worked well for me. e.g.
=b2+a$1
DateTime.new(2012, 1, 15).to_time.to_i
Try the following:
for i in {1..600}; do echo wget http://example.com/search/link$(($i % 5)); done
The $(( ))
syntax does an arithmetic evaluation of the contents.
Using __doPostBack
directly is sooooo the 2000s. Anybody coding WebForms in 2018 uses GetPostBackEventReference
(More seriously though, adding this as an answer for completeness. Using the __doPostBack
directly is bad practice (single underscore prefix typically indicates a private member and double indicates a more universal private member), though it probably won't change or become obsolete at this point. We have a fully supported mechanism in ClientScriptManager.GetPostBackEventReference.)
Assuming your btnRefresh is inside our UpdatePanel and causes a postback, you can use GetPostBackEventReference like this (inspiration):
function RefreshGrid() {
<%= ClientScript.GetPostBackEventReference(btnRefresh, String.Empty) %>;
}

Please note that you have to put the code before setcontentview..
HAPPY CODING!
A compiler may place structure members on particular byte boundaries for reasons of performance on a particular architecture. This may leave unused padding between members. Structure packing forces members to be contiguous.
This may be important for example if you require a structure to conform to a particular file or communications format where the data you need the data to be at specific positions within a sequence. However such usage does not deal with endian-ness issues, so although used, it may not be portable.
It may also to exactly overlay the internal register structure of some I/O device such as a UART or USB controller for example, in order that register access be through a structure rather than direct addresses.
In regards to your code, see @Coulton. You'll need to use JavaScript.
Checkout either FitText (it does work in IE, they just ballsed their site somehow) or BigText.
FitText will allow you to scale some text in relation to the container it is in, while BigText is more about resizing different sections of text to be the same width within the container.
BigText will set your string to exactly the width of the container, whereas FitText is less pixel perfect. It starts by setting the font-size at 1/10th of the container element's width. It doesn't work very well with all fonts by default, but it has a setting which allows you to decrease or increase the 'power' of the re-size. It also allows you to set a min and max font-size. It will take a bit of fiddling to get working the first time, but does work great.
http://marabeas.io <- playing with it currently here. As far as I understand, BigText wouldn't work in my context at all.
For those of you using Angularjs, here's an Angular version of FitText I've made.
Here's a LESS mixin you can use to make @humanityANDpeace's solution a little more pretty:
@mqIterations: 19;
.fontResize(@i) when (@i > 0) {
@media all and (min-width: 100px * @i) { body { font-size:0.2em * @i; } }
.fontResize((@i - 1));
}
.fontResize(@mqIterations);
And an SCSS version thanks to @NIXin!
$mqIterations: 19;
@mixin fontResize($iterations) {
$i: 1;
@while $i <= $iterations {
@media all and (min-width: 100px * $i) { body { font-size:0.2em * $i; } }
$i: $i + 1;
}
}
@include fontResize($mqIterations);
In EF 6.2 using FluentAPI, you can use HasIndex()
modelBuilder.Entity<User>().HasIndex(u => u.UserName).IsUnique();
According to the URI standard the path is for hierarchical parameters and the query is for non-hierarchical parameters. Ofc. it can be very subjective what is hierarchical for you.
In situations where multiple URIs are assigned to the same resource I like to put the parameters - necessary for identification - into the path and the parameters - necessary to build the representation - into the query. (For me this way it is easier to route.)
For example:
/users/123
and /users/123?fields="name, age"
/users
and /users?name="John"&age=30
For map reduce I like to use the following approaches:
/users?name="John"&age=30
/users/name:John/age:30
So it is really up to you (and your server side router) how you construct your URIs.
note: Just to mention these parameters are query parameters. So what you are really doing is defining a simple query language. By complex queries (which contain operators like and, or, greater than, etc.) I suggest you to use an already existing query language. The capabilities of URI templates are very limited...
Even without cloning or fetching, you can check the list of tags on the upstream repo with git ls-remote
:
git ls-remote --tags /url/to/upstream/repo
(as illustrated in "When listing git-ls-remote why there's “^{}
” after the tag name?")
xbmono illustrates in the comments that quotes are needed:
git ls-remote --tags /some/url/to/repo "refs/tags/MyTag^{}"
Note that you can always push your commits and tags in one command with (git 1.8.3+, April 2013):
git push --follow-tags
See Push git commits & tags simultaneously.
Regarding Atlassian SourceTree specifically:
Note that, from this thread, SourceTree ONLY shows local tags.
There is an RFE (Request for Enhancement) logged in SRCTREEWIN-4015
since Dec. 2015.
A simple workaround:
see a list of only unpushed tags?
git push --tags
or check the "
Push all tags
" box on the "Push" dialog box, all tags will be pushed to your remote.
That way, you will be "sure that they are present in remote so that other developers can pull them".
In my case (Windows XP + Apache2.2 + PHP 5.4.31) I changed PHPIniDir
in the httpd.conf
to get around this problem:
from:
"C:\php5\"
to:
"C:/php5/"
Here is a little snippet If you’re trying to check wether element contains a class, without using jQuery.
function hasClass(element, className) {
return element.className && new RegExp("(^|\\s)" + className + "(\\s|$)").test(element.className);
}
This accounts for the fact that element might contain multiple class names separated by space.
OR
You can also assign this function to element prototype.
Element.prototype.hasClass = function(className) {
return this.className && new RegExp("(^|\\s)" + className + "(\\s|$)").test(this.className);
};
And trigger it like this (very similar to jQuery’s .hasClass()
function):
document.getElementById('MyDiv').hasClass('active');
I've got another solution for that problem:
List<String> list = Arrays.asList(split);
List<String> newList = new ArrayList<>(list);
work on newList
;)
You can't wrap that text as it's unbroken without any spaces. You need a JavaScript or server side solution which splits the string after a few characters.
EDIT
You need to add this property in CSS.
word-wrap: break-word;
It can also be as simple as this.
@media (orientation: landscape) {
}

In our case the error appeared because of the incorrect groupId renaming while some of the projects in multi-module Maven configuration references to others.
We had an aggregator project (billing-parent
) with two modules (billing-api
, billing
):
com.company.team:billing-parent
|-com.company.team:billing-api
|-com.company.team:billing
Project billing
depends on billing-api
. So in its pom.xml
it had:
<dependency>
<groupId>com.company.team</groupId>
<artifactId>billing-api</artifactId>
<version>${project.version}</version>
</dependency>
We decided to rename groupId from com.company.team
to com.company.team.billing
. We replaced old value in parent's pom.xml
and in <parent>
sections of both modules. But forgot to update dependency above. So we had got configuration in which billing
project references old billing-api
artifact. Eventually it beaks build of the billing
module after some time with the error like
[ERROR] Failed to execute goal on project billing: Could not resolve dependencies for project com.company.team.billing:billing:jar:3.5.1-SNAPSHOT: Failed to collect dependencies at com.company.team:billing-api:jar:3.5.1-SNAPSHOT: Failed to read artifact descriptor for com.company.team:billing-api:jar:3.5.1-SNAPSHOT: Failure to find <parent of the com.company.team:billing-parent project which is not available any more>
despite the fact that billing-api
module builds without errors.
Solution 1: rename groupId
in dependency
as well.
Solution 2: replace groupId
by the ${project.groupId}
property like this:
<dependency>
<groupId>${project.groupId}</groupId>
<artifactId>billing-api</artifactId>
<version>${project.version}</version>
</dependency>
Conclusion.
So my advice in case you encountered with the error in multi-module configuration whould be: thoroughly check groupId
and artifactId
of the dependencies on neighbour modules.
Sure there is. Here is a way to sum the values of a dictionary.
>>> d = {'key1':1,'key2':14,'key3':47}
>>> sum(d.values())
62
Completing @chuck answer for using composite indices with foreign keys.
You need to define a property that will hold the value of the foreign key. You can then use this property inside the index definition.
For example, we have company with employees and only we have a unique constraint on (name, company) for any employee:
class Company
{
public Guid Id { get; set; }
}
class Employee
{
public Guid Id { get; set; }
[Required]
public String Name { get; set; }
public Company Company { get; set; }
[Required]
public Guid CompanyId { get; set; }
}
Now the mapping of the Employee class:
class EmployeeMap : EntityTypeConfiguration<Employee>
{
public EmployeeMap ()
{
ToTable("Employee");
Property(p => p.Id)
.HasDatabaseGeneratedOption(DatabaseGeneratedOption.None);
Property(p => p.Name)
.HasUniqueIndexAnnotation("UK_Employee_Name_Company", 0);
Property(p => p.CompanyId )
.HasUniqueIndexAnnotation("UK_Employee_Name_Company", 1);
HasRequired(p => p.Company)
.WithMany()
.HasForeignKey(p => p.CompanyId)
.WillCascadeOnDelete(false);
}
}
Note that I also used @niaher extension for unique index annotation.
The commandline interpreter does indeed have a FOR construct that you can use from the command prompt or from within a batch file.
For your purpose, you probably want something like:
FOR %i IN (*.ext) DO my-function %i
Which will result in the name of each file with extension *.ext in the current directory being passed to my-function (which could, for example, be another .bat file).
The (*.ext)
part is the "filespec", and is pretty flexible with how you specify sets of files. For example, you could do:
FOR %i IN (C:\Some\Other\Dir\*.ext) DO my-function %i
To perform an operation in a different directory.
There are scores of options for the filespec and FOR in general. See
HELP FOR
from the command prompt for more information.
You have to write your own method in this case. Use a loop and get each character using charAt(i)
and set it to your Character[]
array using arrayname[i] = string.charAt[i]
.
A simple alternative is to use the new sessionStorage object. Per the comments, if you have 'continue where I left off' checked, sessionStorage will persist between restarts.
Create the symlink to latest version

If you're not completely attached to using "from" and "to" as your option names, it's fairly easy to implement this using getopts:
while getopts f:t: opts; do
case ${opts} in
f) FROM_VAL=${OPTARG} ;;
t) TO_VAL=${OPTARG} ;;
esac
done
getopts
is a program that processes command line arguments and conveniently parses them for you.
f:t:
specifies that you're expecting 2 parameters that contain values (indicated by the colon). Something like f:t:v
says that -v
will only be interpreted as a flag.
opts
is where the current parameter is stored. The case
statement is where you will process this.
${OPTARG}
contains the value following the parameter. ${FROM_VAL}
for example will get the value /home/kristoffer/test.png
if you ran your script like:
ocrscript.sh -f /home/kristoffer/test.png -t /home/kristoffer/test.txt
As the others are suggesting, if this is your first time writing bash scripts you should really read up on some basics. This was just a quick tutorial on how getopts
works.
As per Oracle Glossary :
SID is a unique name for an Oracle database instance. ---> To switch between Oracle databases, users must specify the desired SID <---. The SID is included in the CONNECT DATA parts of the connect descriptors in a TNSNAMES.ORA file, and in the definition of the network listener in the LISTENER.ORA file. Also known as System ID. Oracle Service Name may be anything descriptive like "MyOracleServiceORCL". In Windows, You can your Service Name running as a service under Windows Services.
You should use SID in TNSNAMES.ORA as a better approach.
Yes, it is intended. Here you can read detailed explanation. It is possible to override this behavior by setting SO_REUSEADDR option on a socket. For example:
sock.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
If your server is Ubuntu and Apache version is 2.4
Server version: Apache/2.4.29 (Ubuntu)
Then you export variables in "/etc/apache2/envvars" location.

After enough googling I found the answer from controller you need only a backslash like return \Response::json(['success' => 'hi, atiq']);
. Or you can just return the array return array('success' => 'hi, atiq');
which will be rendered as json in Laravel version 5.2 .
Many of the existing answers assume you want to set this for a particular project, but I needed to set it for Eclipse itself in order to support integrated authentication for the SQL Server JDBC driver.
To do this, I followed these instructions for launching Eclipse from the Java commandline instead of its normal launcher. Then I just modified that script to add my -Djava.library.path argument to the Java commandline.

If the IBM mainframe JCL has some extra characters or numbers at the end of the name of unix script being called then it can throw such error.
Near the top of the file, you need to write var fadeDiv = ...
instead of fadeDiv = ...
so that the variable is actually declared.
The error "Property 'fadeDiv' does not exist on type '{}'.
" seems to be triggering on a line you haven't posted in your example (there is no access of a fadeDiv
property anywhere in that snippet).

I was solving same problem recently. I was designing a write cmdlet for my Subtitle module. I had six different user stories:
I end up in the big frustration because I though that 4 parameters will be enough. Like most of the times, the frustration was pointless because it was my fault. I didn't know enough about parameter sets.
After some research in documentation, I realized where is the problem. With knowledge how the parameter sets should be used, I developed a general and simple approach how to solve this problem. A pencil and a sheet of paper is required but a spreadsheet editor is better:
Example:
The practical example could be seen over here.
BTW: The parameter uniqueness within parameter sets is the reason why the ParameterSetName
property doesn't support [String[]]
. It doesn't really make any sense.
If you want a really hacky one-liner using regular expressions and interpolated strings...
const splitString = (value, idx) => value.split(new RegExp(`(?<=^.{${idx}})`));
console.log(splitString('abcdefgh', 5));
_x000D_
This code says split the string by replacing the value returned in the regex. The regex returns a position, not a character, so we don't lose in characters in the initial string. The way it does this is finding the position, via a look-behind and the ^
anchor, where there were index
characters from the start of the string.
To solve your proposed problem of adding commas every third position from the end, the regex would be slightly different and we'd use replace rather than split.
const values = [ 8211, 98700, 1234567890 ];
const addCommas = (value, idx) => value.replace(new RegExp(`(?=(.{${idx}})+$)`, 'g'), ',');
console.log(values.map(v => addCommas(v.toString(), 3)));
_x000D_
Here we find the idx
th position from the end by using a look-ahead and the $
anchor, but we also capture any number of those sets of positions from the end. Then we replace the position with a comma. We use the g
flag (global) so it replaces every occurrence, not just the first found.
Keep in mind that the previous example:
db.stuff.find( { foo: /bar/i } );
will cause every entries containing bar to match the query ( bar1, barxyz, openbar ), it could be very dangerous for a username search on a auth function ...
You may need to make it match only the search term by using the appropriate regexp syntax as:
db.stuff.find( { foo: /^bar$/i } );
See http://www.regular-expressions.info/ for syntax help on regular expressions
For attached properties you can either call SetValue on the object for which you want to assign the value:
tblock.SetValue(Grid.RowProperty, 4);
Or call the static Set method (not as an instance method like you tried) for the property on the owner type, in this case SetRow:
Grid.SetRow(tblock, 4);

$ ./serp --root test --search hi --replace bye --pattern "*"
test/z: replace hi with bye? (y/[n]) y
$ cat test/z

Because str
in python2 is bytes
actually. So if want to write unicode
to csv, you must encode unicode
to str
using utf-8
encoding.
def py2_unicode_to_str(u):
# unicode is only exist in python2
assert isinstance(u, unicode)
return u.encode('utf-8')
Use class csv.DictWriter(csvfile, fieldnames, restval='', extrasaction='raise', dialect='excel', *args, **kwds)
:
csvfile
: open(fp, 'w')
bytes
which are encoded with utf-8
writer.writerow({py2_unicode_to_str(k): py2_unicode_to_str(v) for k,v in row.items()})
csvfile
: open(fp, 'w')
str
as row
to writer.writerow(row)
Finally code
import sys
is_py2 = sys.version_info[0] == 2

# unicode is only exist in python2
assert isinstance(u, unicode)
return u.encode('utf-8')

In python3, just use the unicode str
.
In python2, use unicode
handle text, use str
when I/O occurs.
I have build a small demo project on this you could have a look to it Link to project
You could use os.listdir()
which returns a list of names (for both files and directories) in a given directory. If you need to distinguish between files and directories, call os.stat()
on each name.
For Eclipse Mars (I've just verified that) you to do this (assuming that C:\eclipseMarsEE is root folder of your Eclipse):
# Column Non-Null Count Dtype
--- ------ -------------- -----
0 startDay 110526 non-null object
1 endDay 110526 non-null object
import pandas as pd
df['startDay'] = pd.to_datetime(df.startDay)
df['endDay'] = pd.to_datetime(df.endDay)
# Column Non-Null Count Dtype

0 startDay 110526 non-null datetime64[ns]

select * from Table1 left join Table2 on Table1.id = Table2.id
In the first query Left join compares left-sided table table1 to right-sided table table2.
In Which all the properties of table1 will be shown, whereas in table2 only those properties will be shown in which condition get true.
select * from Table2 right join Table1 on Table1.id = Table2.id
In the first query Right join compares right-sided table table1 to left-sided table table2.
In Which all the properties of table1 will be shown, whereas in table2 only those properties will be shown in which condition get true.
Both queries will give the same result because the order of table declaration in query are different like you are declaring table1 and table2 in left and right respectively in first left join query, and also declaring table1 and table2 in right and left respectively in second right join query.
This is the reason why you are getting the same result in both queries. So if you want different result then execute this two queries respectively,
select * from Table1 left join Table2 on Table1.id = Table2.id
select * from Table1 right join Table2 on Table1.id = Table2.id
targetList = list1.Concat(list2).ToList();
It's working fine I think so. As previously said, Concat returns a new sequence and while converting the result to List, it does the job perfectly. Implicit conversions may fail sometimes when using the AddRange method.
I believe that your problem is due to the fact that you are defining the variable v inside the test. As explained by @rmalchow, it will work you change it into
int v;
if((v = someMethod()) != 0) return true;
There is also another issue of variable scope. Even if what you tried were to work, what would be the point? Assuming you could define the variable scope inside the test, your variable v would not exist outside that scope. Hence, creating the variable and assigning the value would be pointless, for you would not be able to use it.
Variables exist only in the scope they were created. Since you are assigning the value to use it afterwards, consider the scope where you are creating the varible so that it may be used where needed.
This is a pretty common proof. One way to prove this is to use mathematical induction. Here is a link: http://zimmer.csufresno.edu/~larryc/proofs/proofs.mathinduction.html
In reply to Dimitrys answer but using Ajax.BeginForm
the following works at least with MVC >5 (4 not tested).
write a model as shown in the other answers,
In the "parent view" you will probably use a table to show the data.
Model should be an ienumerable. I assume, the model has an id
-property. Howeverm below the template, a placeholder for the modal and corresponding javascript
<table>
@foreach (var item in Model)
{
<tr> <td id="[email protected]">
@Html.Partial("dataRowView", item)
</td> </tr>
}
</table>
<div class="modal fade" id="editor-container" tabindex="-1"
role="dialog" aria-labelledby="editor-title">
<div class="modal-dialog modal-lg" role="document">
<div class="modal-content" id="editor-content-container"></div>
</div>
</div>
<script type="text/javascript">
$(function () {
$('.editor-container').click(function () {
var url = "/area/controller/MyEditAction";
var id = $(this).attr('data-id');
$.get(url + '/' + id, function (data) {
$('#editor-content-container').html(data);
$('#editor-container').modal('show');
});
});
});
function success(data,status,xhr) {
$('#editor-container').modal('hide');
$('#editor-content-container').html("");
}
function failure(xhr,status,error) {
$('#editor-content-container').html(xhr.responseText);
$('#editor-container').modal('show');
}
</script>
note the "editor-success-id" in data table rows.
The dataRowView
is a partial containing the presentation of an model's item.
@model ModelView
@{
var item = Model;
}
<div class="row">
// some data
<button type="button" class="btn btn-danger editor-container" data-id="@item.Id">Edit</button>
</div>
Write the partial view that is called by clicking on row's button (via JS $('.editor-container').click(function () ...
).
@model Model
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
<h4 class="modal-title" id="editor-title">Title</h4>
</div>
@using (Ajax.BeginForm("MyEditAction", "Controller", FormMethod.Post,
new AjaxOptions
{
InsertionMode = InsertionMode.Replace,
HttpMethod = "POST",
UpdateTargetId = "editor-success-" + @Model.Id,
OnSuccess = "success",
OnFailure = "failure",
}))
{
@Html.ValidationSummary()
@Html.AntiForgeryToken()
@Html.HiddenFor(model => model.Id)
<div class="modal-body">
<div class="form-horizontal">
// Models input fields
</div>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Cancel</button>
<button type="submit" class="btn btn-primary">Save</button>
</div>
}
This is where magic happens: in AjaxOptions
, UpdateTargetId will replace the data row after editing, onfailure and onsuccess will control the modal.
This is, the modal will only close when editing was successful and there have been no errors, otherwise the modal will be displayed after the ajax-posting to display error messages, e.g. the validation summary.
But how to get ajaxform to know if there is an error? This is the controller part, just change response.statuscode as below in step 5:
the corresponding controller action method for the partial edit modal
[HttpGet]
public async Task<ActionResult> EditPartData(Guid? id)
{
// Find the data row and return the edit form
Model input = await db.Models.FindAsync(id);
return PartialView("EditModel", input);
}
[HttpPost, ValidateAntiForgeryToken]
public async Task<ActionResult> MyEditAction([Bind(Include =
"Id,Fields,...")] ModelView input)
{
if (TryValidateModel(input))
{
// save changes, return new data row
// status code is something in 200-range
db.Entry(input).State = EntityState.Modified;
await db.SaveChangesAsync();
return PartialView("dataRowView", (ModelView)input);
}
// set the "error status code" that will redisplay the modal
Response.StatusCode = 400;
// and return the edit form, that will be displayed as a
// modal again - including the modelstate errors!
return PartialView("EditModel", (Model)input);
}
This way, if an error occurs while editing Model data in a modal window, the error will be displayed in the modal with validationsummary methods of MVC; but if changes were committed successfully, the modified data table will be displayed and the modal window disappears.
Note: you get ajaxoptions working, you need to tell your bundles configuration to bind jquery.unobtrusive-ajax.js
(may be installed by NuGet):
bundles.Add(new ScriptBundle("~/bundles/jqueryajax").Include(
"~/Scripts/jquery.unobtrusive-ajax.js"));
If I understood it right you are doing an XMLHttpRequest to a different domain than your page is on. So the browser is blocking it as it usually allows a request in the same origin for security reasons. You need to do something different when you want to do a cross-domain request. A tutorial about how to achieve that is Using CORS.
When you are using postman they are not restricted by this policy. Quoted from Cross-Origin XMLHttpRequest:
Regular web pages can use the XMLHttpRequest object to send and receive data from remote servers, but they're limited by the same origin policy. Extensions aren't so limited. An extension can talk to remote servers outside of its origin, as long as it first requests cross-origin permissions.
Code:
List<String> list = new ArrayList<String>();
list.add("a");
JSONArray array = new JSONArray();
for (int i = 0; i < list.size(); i++) {
array.put(list.get(i));
}
JSONObject obj = new JSONObject();
try {
obj.put("result", array);
} catch (JSONException e) {
e.printStackTrace();
}
The intended use of App_data is to store application data for the web process to acess. It should not be viewable by the web and is a place for the web app to store and read data from.
Your question almost spells the SQL for this:
DELETE FROM table WHERE id IN (1, 4, 6, 7)
I think @Erlend's use of HTMLDocument
is the best way to go. However, I have also had good luck using this simple library:
I assume "direction" is "ASC" or "DESC" and dt contains a column named "colName"
public static DataTable resort(DataTable dt, string colName, string direction)
{
DataTable dtOut = null;
dt.DefaultView.Sort = colName + " " + direction;
dtOut = dt.DefaultView.ToTable();
return dtOut;
}
OR without creating dtOut
public static DataTable resort(DataTable dt, string colName, string direction)
{
dt.DefaultView.Sort = colName + " " + direction;
dt = dt.DefaultView.ToTable();
return dt;
}
You can use delegate_to
to run commands on your Ansible host (admin host), from where you are running your Ansible play. For example:
Delete a file if it already exists on Ansible host:
- name: Remove file if already exists
file:
path: /tmp/logfile.log
state: absent
mode: "u+rw,g-wx,o-rwx"
delegate_to: 127.0.0.1
Create a new file on Ansible host :
- name: Create log file
file:
path: /tmp/logfile.log
state: touch
mode: "u+rw,g-wx,o-rwx"
delegate_to: 127.0.0.1
Sometime we should see the note from the warnin SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.
.
This happens when no appropriate SLF4J binding could be found on the class path
You can search the reason why this warning comes.
Adding one of the jar from *slf4j-nop.jar
, slf4j-simple.jar
, slf4j-log4j12.jar
, slf4j-jdk14.jar
or logback-classic.jar*
to the class path should solve the problem.
compile "org.slf4j:slf4j-simple:1.6.1"
for example add the above code to your build.gradle
or the corresponding code to pom.xml
for maven project.
You get a recursion error because your attempt to access the self.__dict__
attribute inside __getattribute__
invokes your __getattribute__
again. If you use object
's __getattribute__
instead, it works:
class D(object):
def __init__(self):
self.test=20
self.test2=21
def __getattribute__(self,name):
if name=='test':
return 0.
else:
return object.__getattribute__(self, name)
This works because object
(in this example) is the base class. By calling the base version of __getattribute__
you avoid the recursive hell you were in before.
Ipython output with code in foo.py:
In [1]: from foo import *
In [2]: d = D()
In [3]: d.test
Out[3]: 0.0
In [4]: d.test2
Out[4]: 21
Update:
There's something in the section titled More attribute access for new-style classes in the current documentation, where they recommend doing exactly this to avoid the infinite recursion.
You are looking for the request history.
The response.history
attribute is a list of responses that led to the final URL, which can be found in response.url
.
response = requests.get(someurl)
if response.history:
print("Request was redirected")
for resp in response.history:
print(resp.status_code, resp.url)
print("Final destination:")
print(response.status_code, response.url)
else:
print("Request was not redirected")
Demo:
>>> import requests
>>> response = requests.get('http://httpbin.org/redirect/3')
>>> response.history
(<Response [302]>, <Response [302]>, <Response [302]>)
>>> for resp in response.history:
... print(resp.status_code, resp.url)
...
302 http://httpbin.org/redirect/3
302 http://httpbin.org/redirect/2
302 http://httpbin.org/redirect/1
>>> print(response.status_code, response.url)

I tried the procedures of your posts but with no success.
This is what I get from debugger:
Original string that I save into sqlite database was b\r\na
.. when I read them, I get b\\r\\na
(length in debugger is 6: "b" "\" "\r" "\" "\n" "a"
) then I try replace this string and I get string with length 6 again (you can see in picture above).
I run this short script in my test form with only one text box:
private void Form_Load(object sender, EventArgs e)
{
string x = "b\\r\\na";
string y = x.Replace(@"\\", @"\");
this.textBox.Text = y + "\r\n\r\nLength: " + y.Length.ToString();
}
and I get this in text box (so, no new line characters between "b" and "a":
b\r\na
Length: 6
What can I do with this string to unescape backslash? (I expect new line between "b" and "a".)
Solution:
OK, this is not possible to do with standard replace, because of \r
and \n
is one character. Is possible to replace part of string character by character but not possible to replace "half part" of one character. So, I must replace any special character separatelly, like this:
private void Form_Load(object sender, EventArgs e) {
...
string z = x.Replace(@"\r\n", Environment.NewLine);
...
This produce correct result for me:
b
a
Fix: Unlock your device before running it.
Hi Guys: Think I may have a fix for this:
Sounds ridiculous but try unlocking your Virtual Device; i.e. use your mouse to swipe and open. Your app should then work!!
I figured it out. I had an error in my cloud formation template that was creating the EC2 instances. As a result, the EC2 instances that were trying to access the above code deploy buckets, were in different regions (not us-west-2). It seems like the access policies on the buckets (owned by Amazon) only allow access from the region they belong in. When I fixed the error in my template (it was wrong parameter map), the error disappeared
Choose one you need:
>>> s = "Rajasekar SP def"
>>> s.split(' ')
['Rajasekar', 'SP', '', 'def']
>>> s.split()
['Rajasekar', 'SP', 'def']
>>> s.partition(' ')
('Rajasekar', ' ', 'SP def')
If it's a submodule you need to cd into it then use git add . && git commit -m 'Your message'
From there you can cd out and push to whichever branch you want.
One of The Shortest method i found for single value while i was searching for myself, is just passing single string and setting string as model in view like this.
In your Partial calling side
@Html.Partial("ParitalAction", "String data to pass to partial")
And then binding the model with Partial View like this
@model string
and the using its value in Partial View like this
@Model
You can also play with other datatypes like array, int or more complex data types like IDictionary or something else.
Hope it helps,
Good guestion! -- where I have not yet found a satisfying answer for my case, the answer I provide here works for me, but may not be future proof...
If one uses gcc (clang?) and have -Werror
and -Wbad-function-cast
defined,
int val = (int)pow(10,9);
will result:
error: cast from function call of type 'double' to non-matching type 'int' [-Werror=bad-function-cast]
(for a good reason, overflow and where values are rounded needs to be thought out)
EDIT: 2020-08-30: So, my use case casting the value from function returning double to int, and chose pow() to represent that in place of a private function somewhere. Then I sidestepped thinking pow() more. (See comments more why pow() used below could be problematic...).
After properly thought out (that parameters to pow() are good), int val = pow(10,9);
seems to work with gcc 9.2 x86-64 ...
but note:
printf("%d\n", pow(10,4));
may output e.g.
-1121380856
(did for me) where
int i = pow(10,4); printf("%d\n", i);
printed
10000
in one particular case I tried.
Your string is wider than your format width of 2. So there's no padding to be done.
I am using httpclient 4.4.
For solr query I used the following way and it worked.
NameValuePair nv2 = new BasicNameValuePair("fq","(active:true) AND (category:Fruit OR category1:Vegetable)");
nvPairList.add(nv2);
NameValuePair nv3 = new BasicNameValuePair("wt","json");
nvPairList.add(nv3);
NameValuePair nv4 = new BasicNameValuePair("start","0");
nvPairList.add(nv4);
NameValuePair nv5 = new BasicNameValuePair("rows","10");
nvPairList.add(nv5);
HttpClient client = HttpClientBuilder.create().build();
HttpGet request = new HttpGet(url);
URI uri = new URIBuilder(request.getURI()).addParameters(nvPairList).build();
request.setURI(uri);
HttpResponse response = client.execute(request);
if (response.getStatusLine().getStatusCode() != 200) {
}
BufferedReader br = new BufferedReader(
new InputStreamReader((response.getEntity().getContent())));
String output;
System.out.println("Output .... ");
String respStr = "";
while ((output = br.readLine()) != null) {
respStr = respStr + output;
System.out.println(output);
}
In addition to others comments, something to look out for is the status returned from your underlying integration and if the Access-Control-Allow-Origin header is returned for that status.
Doing the 'Enable CORS' thing only sets up 200 status. If you have others on the endpoint, e.g 4xx and 5xx, you need to add the header yourself.
You were on the right track with response.getOutputStream()
, but you're not using its output anywhere in your code. Essentially what you need to do is to stream the PDF file's bytes directly to the output stream and flush the response. In Spring you can do it like this:
@RequestMapping(value="/getpdf", method=RequestMethod.POST)
public ResponseEntity<byte[]> getPDF(@RequestBody String json) {
// convert JSON to Employee
Employee emp = convertSomehow(json);
// generate the file
PdfUtil.showHelp(emp);
// retrieve contents of "C:/tmp/report.pdf" that were written in showHelp
byte[] contents = (...);
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_PDF);
// Here you have to set the actual filename of your pdf
String filename = "output.pdf";
headers.setContentDispositionFormData(filename, filename);
headers.setCacheControl("must-revalidate, post-check=0, pre-check=0");
ResponseEntity<byte[]> response = new ResponseEntity<>(contents, headers, HttpStatus.OK);
return response;
}
Notes:
showHelp
is not a good ideabyte[]
: example hereshowHelp()
to avoid overwriting the file if two users send a request at the same timeI also faced the error code when i upgraded my java version to 1.8. The problem was with my eclipse.
My jdk which was installed on my system is of 32 - bit and my eclipse was of 64 - bit.
So solve this problem i downloaded the 32 - bit eclipse.
IMO this Architecture miss match problem
Plese match your architecture type of JDK and eclipse.
First, I strongly recommend that you rename your variable list
to something else. list
is the name of the built-in list constructor, and you're hiding its normal function. I will rename list
to a
in the following.
Python names are references that are bound to objects. That means that unless you create more than one list, whenever you use a
it's referring to the same actual list object as last time. So when you call
listoflists.append((a, a[0]))
you can later change a
and it changes what the first element of that tuple points to. This does not happen with a[0]
because the object (which is an integer) pointed to by a[0]
doesn't change (although a[0]
points to different objects over the run of your code).
You can create a copy of the whole list a
using the list
constructor:
listoflists.append((list(a), a[0]))
Or, you can use the slice notation to make a copy:
listoflists.append((a[:], a[0]))
Full Screen Custom Alert Dialog Class in Kotlin
Create XML file, same as you would an activity
Create AlertDialog custom class
class Your_Class(context:Context) : AlertDialog(context){
init {
requestWindowFeature(Window.FEATURE_NO_TITLE)
setCancelable(false)
}
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.your_Layout)
val window = this.window
window?.setLayout(WindowManager.LayoutParams.MATCH_PARENT,
WindowManager.LayoutParams.MATCH_PARENT)
//continue custom code here
//call dismiss() to close
}
}
Call the dialog within the activity
val dialog = Your_Class(this)
//can set some dialog options here
dialog.show()
Note**: If you do not want your dialog to be full screen, delete the following lines
val window = this.window
window?.setLayout(WindowManager.LayoutParams.MATCH_PARENT,
WindowManager.LayoutParams.MATCH_PARENT)
Then edit the layout_width & layout_height of your top layout within your XML file to be either wrap_content or a fixed DP value.
I generally do not recommend using fixed DP as you would likely want your app to be adaptable to multiple screen sizes, however if you keep your size values small enough you should be fine
Try this..

You can try to apply new architecture approach anounced at Google I/O 2017.
It also includes new ORM library called Room
It contains three main components: @Entity, @Dao and @Database
User.java
@Entity
public class User {
@PrimaryKey
private int uid;
@ColumnInfo(name = "first_name")
private String firstName;
@ColumnInfo(name = "last_name")
private String lastName;
// Getters and setters are ignored for brevity,
// but they're required for Room to work.
}
UserDao.java
@Dao
public interface UserDao {
@Query("SELECT * FROM user")
List<User> getAll();
@Query("SELECT * FROM user WHERE uid IN (:userIds)")
List<User> loadAllByIds(int[] userIds);
@Query("SELECT * FROM user WHERE first_name LIKE :first AND "
+ "last_name LIKE :last LIMIT 1")
User findByName(String first, String last);
@Insert
void insertAll(User... users);
@Delete
void delete(User user);
}
AppDatabase.java
@Database(entities = {User.class}, version = 1)
public abstract class AppDatabase extends RoomDatabase {
public abstract UserDao userDao();
}
As Ajay beniwal mentioned above you need to use Apply to start digestion.
var app = angular.module('test', []);
app.controller('TestCtrl', function ($scope) {
$scope.testValue = 0;
setInterval(function() {
console.log($scope.testValue++);
$scope.$apply()
}, 500);
});
I do it like this:
.hidden-text {
left: 100%;
display: inline-block;
position: fixed;
}
Before stumbling onto this post, I came up with this solution - to toggle the TopMost property:
this.TopMost = true;
this.TopMost = false;
I have this code in my form's constructor, eg:
public MyForm()
{
//...
// Brint-to-front hack
this.TopMost = true;
this.TopMost = false;
//...
}
/**
* Forbids special characters and decimals
* Allows numbers only
* */
const numbersOnly = (evt) => {
let charCode = (evt.which) ? evt.which : evt.keyCode;
if (charCode === 46 && charCode > 31 && (charCode < 48 || charCode > 57)) {
return false;
}
let inputResult = /^[0-9]*$/.test(evt.target.value);
if (!inputResult) {
evt.target.value = evt.target.value.replace(/[^a-z0-9\s]/gi, '');
}
return true;
}
See RFC 5322: Internet Message Format and, to a lesser extent, RFC 5321: Simple Mail Transfer Protocol.
RFC 822 also covers email addresses, but it deals mostly with its structure:
addr-spec = local-part "@" domain ; global address
local-part = word *("." word) ; uninterpreted
; case-preserved
domain = sub-domain *("." sub-domain)
sub-domain = domain-ref / domain-literal
domain-ref = atom ; symbolic reference
And as usual, Wikipedia has a decent article on email addresses:
The local-part of the email address may use any of these ASCII characters:
- uppercase and lowercase Latin letters
A
toZ
anda
toz
;- digits
0
to9
;- special characters
!#$%&'*+-/=?^_`{|}~
;- dot
.
, provided that it is not the first or last character unless quoted, and provided also that it does not appear consecutively unless quoted (e.g.[email protected]
is not allowed but"John..Doe"@example.com
is allowed);- space and
"(),:;<>@[\]
characters are allowed with restrictions (they are only allowed inside a quoted string, as described in the paragraph below, and in addition, a backslash or double-quote must be preceded by a backslash);- comments are allowed with parentheses at either end of the local-part; e.g.
john.smith(comment)@example.com
and(comment)[email protected]
are both equivalent to[email protected]
.
In addition to ASCII characters, as of 2012 you can use international characters above U+007F
, encoded as UTF-8 as described in the RFC 6532 spec and explained on Wikipedia. Note that as of 2019, these standards are still marked as Proposed, but are being rolled out slowly. The changes in this spec essentially added international characters as valid alphanumeric characters (atext) without affecting the rules on allowed & restricted special characters like !#
and @:
.
For validation, see Using a regular expression to validate an email address.
The domain
part is defined as follows:
The Internet standards (Request for Comments) for protocols mandate that component hostname labels may contain only the ASCII letters
a
throughz
(in a case-insensitive manner), the digits0
through9
, and the hyphen (-
). The original specification of hostnames in RFC 952, mandated that labels could not start with a digit or with a hyphen, and must not end with a hyphen. However, a subsequent specification (RFC 1123) permitted hostname labels to start with digits. No other symbols, punctuation characters, or blank spaces are permitted.

The cause is the difference between how a Windows-based based OS and a Unix based OS store the end-of-line markers.
Windows based operating systems, thanks to their DOS heritage, store an end-of-line as a pair of characters - 0x0D0A
(carriage return + line feed). Unix-based operating systems just use 0x0A
(a line feed). The ^M
you're seeing is a visual representation of 0x0D
(a carriage return).
dos2unix will help with this. You probably also need to adjust the source of the scripts to be 'Unix-friendly'.

nameserver 8.8.8.8
nameserver 4.2.2.1
nameserver 2001:4860:4860::8844
nameserver 2001:4860:4860::8888
then run the update script,
resolvconf -u
I have copied the relevant code below from This page. Hope this might help you.

400 Bad Request is proper HTTP status code for your use case. The code is defined by HTTP/0.9-1.1 RFC.
The request could not be understood by the server due to malformed syntax. The client SHOULD NOT repeat the request without modifications.
http://tools.ietf.org/html/rfc2616#section-10.4.1
422 Unprocessable Entity is defined by RFC 4918 - WebDav. Note that there is slight difference in comparison to 400, see quoted text below.
This error condition may occur if an XML request body contains well-formed (i.e., syntactically correct), but semantically erroneous, XML instructions.
To keep uniform interface you should use 422 only in a case of XML responses and you should also support all status codes defined by Webdav extension, not just 422.
http://tools.ietf.org/html/rfc4918#page-78
See also Mark Nottingham's post on status codes:
it’s a mistake to try to map each part of your application “deeply” into HTTP status codes; in most cases the level of granularity you want to be aiming for is much coarser. When in doubt, it’s OK to use the generic status codes 200 OK, 400 Bad Request and 500 Internal Service Error when there isn’t a better fit.
This worked for me:
SELECT * FROM table where date(column_date) = curdate()
As per official documentation link shared by Andre Kirpitch, Oracle 10g gives a maximum size of 4000 bytes or characters for varchar2. If you are using a higher version of oracle (for example Oracle 12c), you can get a maximum size upto 32767 bytes or characters for varchar2. To utilize the extended datatype feature of oracle 12, you need to start oracle in upgrade mode. Follow the below steps in command prompt:
1) Login as sysdba (sqlplus / as sysdba)
2) SHUTDOWN IMMEDIATE;
3) STARTUP UPGRADE;
4) ALTER SYSTEM SET max_string_size=extended;
5) Oracle\product\12.1.0.2\rdbms\admin\utl32k.sql
6) SHUTDOWN IMMEDIATE;
7) STARTUP;
Generally the first 2 package "words" are your web address in reverse. (You'd have 3 here as convention, if you had a subdomain.)
So something stackoverflow produces would likely be in package com.stackoverflow.whatever.customname
something asp.net produces might be called net.asp.whatever.customname.omg.srsly
something from mysubdomain.toplevel.com would be com.toplevel.mysubdomain.whatever
Beyond that simple convention, the sky's the limit. This is an old linux convention for something that I cannot recall exactly...
It's because when you enter a number then press Enter, input.nextInt()
consumes only the number, not the "end of line". Primitive data types like int, double etc do not consume "end of line", therefore the "end of line" remains in buffer and When input.next()
executes, it consumes the "end of line" from buffer from the first input. That's why, your String sentence = scanner.next()
only consumes the "end of line" and does not wait to read from keyboard.
Tip: use scanner.nextLine()
instead of scanner.next()
because scanner.next()
does not read white spaces from the keyboard. (Truncate the string after giving some space from keyboard, only show string before space.)
Functionality-wise they are identical but I use them in the following scenarios to make code readable:
Use die() when there is an error and have to stop the execution.
e.g.
die( 'Oops! Something went wrong' );
Use exit() when there is not an error and have to stop the execution.
e.g.
exit( 'Request has been processed successfully!' );
Access is a great multi-user database. It has lots of built in features to handle the multi-user situation. In fact, it is so very popular because it is such a great multi-user database. There is an upper limit on how many users can all use the database at the same time doing updates and edits - depending on how knowledgeable the developer is about access and how the database has been designed - anywhere from 20 users to approx 50 users. Some access databases can be built to handle up to 50 concurrent users, while many others can handle 20 or 25 concurrent users updating the database. These figures have been observed for databases that have been in use for several or more years and have been discussed many times on the access newsgroups.
View view =(View) getActivity().findViewById(controlId);
Spinner spinner = (Spinner)view.findViewById(R.id.spinner1);
String valToSet = spinner.getSelectedItem().toString();
You are trying to insert data that is larger than allowed for the column logo
.
Use following data types as per your need
TINYBLOB : maximum length of 255 bytes
BLOB : maximum length of 65,535 bytes
MEDIUMBLOB : maximum length of 16,777,215 bytes
LONGBLOB : maximum length of 4,294,967,295 bytes
Use LONGBLOB
to avoid this exception.
You can't run PHP code with Javascript. When the user recieves the page, the server will have evaluated and run all PHP code, and taken it out. So for example, this will work:
alert( <?php echo "\"Hello\""; ?> );
Because server will have evaluated it to this:
alert("Hello");
However, you can't perform any operations in PHP with it.
This:
function Inc()
{
<?php
$num = 2;
echo $num;
?>
}
Will simply have been evaluated to this:
function Inc()
{
2
}
If you wan't to call a PHP script, you'll have to call a different page which returns a value from a set of parameters.
This, for example, will work:
script.php
$num = $_POST["num"];
echo $num * 2;
Javascript(jQuery) (on another page):
$.post('script.php', { num: 5 }, function(result) {
alert(result);
});
This should alert 10.
Good luck!
Edit: Just incrementing a number on the page can be done easily in jQuery like this: http://jsfiddle.net/puVPc/
Don't put the environment configuration in catalina.bat/catalina.sh. Instead you should create a new file in CATALINA_BASE\bin\setenv.bat to keep your customizations separate of tomcat installation.
With Spring MVC 4.2.1.RELEASE, you need to use the new Jackson2 dependencies as below for the Deserializer to work.
Dont use this
<dependency>

Use this instead.

for the deserialization and not the classes from org.codehaus.jackson

The other answers here involving marking the protocol as "@objc" do not work when using swift-specific types.
struct Info {
var height: Int
var weight: Int
}
@objc protocol Health {
func isInfoHealthy(info: Info) -> Bool
}
//Error "Method cannot be marked @objc because the type of the parameter cannot be represented in Objective-C"
In order to declare optional protocols that work well with swift, declare the functions as variables instead of func's.
protocol Health {
var isInfoHealthy: (Info) -> (Bool)? { get set }
}
And then implement the protocol as follows
class Human: Health {
var isInfoHealthy: (Info) -> (Bool)? = { info in
if info.weight < 200 && info.height > 72 {
return true
}
return false
}
//Or leave out the implementation and declare it as:
//var isInfoHealthy: (Info) -> (Bool)?
}
You can then use "?" to check whether or not the function has been implemented
func returnEntity() -> Health {
return Human()
}
var anEntity: Health = returnEntity()
var isHealthy = anEntity.isInfoHealthy(Info(height: 75, weight: 150))?
//"isHealthy" is true
Vendor independent version, solely relies on ADO.NET interfaces; 2 ways:
public DataTable Read1<T>(string query) where T : IDbConnection, new()
{
using (var conn = new T())
{
using (var cmd = conn.CreateCommand())
{
cmd.CommandText = query;
cmd.Connection.ConnectionString = _connectionString;
cmd.Connection.Open();
var table = new DataTable();
table.Load(cmd.ExecuteReader());
return table;
}
}
}
public DataTable Read2<S, T>(string query) where S : IDbConnection, new()
where T : IDbDataAdapter, IDisposable, new()
{
using (var conn = new S())
{
using (var da = new T())
{
using (da.SelectCommand = conn.CreateCommand())
{
da.SelectCommand.CommandText = query;
da.SelectCommand.Connection.ConnectionString = _connectionString;
DataSet ds = new DataSet(); //conn is opened by dataadapter
da.Fill(ds);
return ds.Tables[0];
}
}
}
}
I did some performance testing, and the second approach always outperformed the first.
Stopwatch sw = Stopwatch.StartNew();
DataTable dt = null;
for (int i = 0; i < 100; i++)
{
dt = Read1<MySqlConnection>(query); // ~9800ms
dt = Read2<MySqlConnection, MySqlDataAdapter>(query); // ~2300ms
dt = Read1<SQLiteConnection>(query); // ~4000ms
dt = Read2<SQLiteConnection, SQLiteDataAdapter>(query); // ~2000ms
dt = Read1<SqlCeConnection>(query); // ~5700ms
dt = Read2<SqlCeConnection, SqlCeDataAdapter>(query); // ~5700ms
dt = Read1<SqlConnection>(query); // ~850ms
dt = Read2<SqlConnection, SqlDataAdapter>(query); // ~600ms
dt = Read1<VistaDBConnection>(query); // ~3900ms
dt = Read2<VistaDBConnection, VistaDBDataAdapter>(query); // ~3700ms
}
sw.Stop();
MessageBox.Show(sw.Elapsed.TotalMilliseconds.ToString());
Read1
looks better on eyes, but data adapter performs better (not to confuse that one db outperformed the other, the queries were all different). The difference between the two depended on query though. The reason could be that Load
requires various constraints to be checked row by row from the documentation when adding rows (its a method on DataTable
) while Fill
is on DataAdapters which were designed just for that - fast creation of DataTables.
OpenCV 2.4.2 now comes with the very new cv::FaceRecognizer. Please see the very detailed documentation at:
I have released libfacerec, a modern face recognition library for the OpenCV C++ API (BSD license). libfacerec has no additional dependencies and implements the Eigenfaces method, Fisherfaces method and Local Binary Patterns Histograms. Parts of the library are going to be included in OpenCV 2.4.
The latest revision of the libfacerec is available at:
The library was written for OpenCV 2.3.1 with the upcoming OpenCV 2.4 in mind, so I don't support OpenCV versions earlier than 2.3.1. This project comes as a CMake project with a well-documented API, there's also a tutorial on gender classification. You can see a HTML version of the documentation at:
If you want to understand how those algorithms work, you might want to read my Guide To Face Recognition (includes Python and GNU Octave/MATLAB examples):
There's also a Python and GNU Octave/MATLAB implementation of the algorithms in my github repository. Both projects in facerec also include several cross validation methods for evaluating algorithms:
The relevant publications are:
I find the jQuery select box manipulation plugin useful for this type of thing.
You can easily remove an item by index, value, or regex.
removeOption(index/value/regex/array[, selectedOnly])
Remove an option by
- index: $("#myselect2").removeOption(0);
- value: $("#myselect").removeOption("Value");
- regular expression: $("#myselect").removeOption(/^val/i);
- array $("#myselect").removeOption(["myselect_1", "myselect_2"]);
To remove all options, you can do $("#myselect").removeOption(/./);
.
You can bootstrap multiple angular applications, but:
1) You need to manually bootstrap them
2) You should not use "document" as the root, but the node where the angular interface is contained to:
var todoRootNode = jQuery('[ng-controller=TodoController]');
angular.bootstrap(todoRootNode, ['TodoApp']);
This would be safe.
Here is your Tag.
<asp:LinkButton ID="LinkButton1" runat="server">Open Test Page</asp:LinkButton>
Here is your code on the code behind.
LinkButton1.Attributes.Add("href","../Test.aspx")
LinkButton1.Attributes.Add("target","_blank")
Hope this will be helpful for someone.
Edit To do the same with a link button inside a template field, use the following code.
Use GridView_RowDataBound event to find Link button.
Dim LB as LinkButton = e.Row.FindControl("LinkButton1")
LB.Attributes.Add("href","../Test.aspx")
LB.Attributes.Add("target","_blank")
On MVC 5 is quite similar
@Html.ActionLink("LinkText", "ActionName", new { id = "id" })
add float: left property to the image.
#rb-menu-com li .submenu div img {
border:1px solid #fff;
float:left;
}

.sr-only
is a class name specifically used for screen readers. You can use any class name, but .sr-only
is pretty commonly used. If you don't care about developing with compliance in mind, then it can be removed. It will not affect UI in any way if removed because the CSS for this class is not visible to desktop and mobile device browsers.
There seems to be some information missing here about the use of .sr-only
to explain its purpose and being for screen readers. First and foremost, it is very important to always keep impaired users in mind. Impairment is the purpose of 508 compliance: https://www.section508.gov/, and it is great that bootstrap takes this into consideration. However, the use of .sr-only
is not all that needs to be taken into consideration for 508 compliance. You have the use of color, size of fonts, accessibility via navigation, descriptors, use of aria and so much more.
But as for .sr-only
- what does the CSS actually do? There are several slightly different variants of the CSS used for .sr-only
. One of the few I use is below:
.sr-only {
position: absolute;
margin: -1px 0 0 -1px;
padding: 0;
display: block;
width: 1px;
height: 1px;
font-size: 1px;
line-height: 1px;
overflow: hidden;
clip: rect(0,0,0,0);
border: 0;
outline: 0;
}
The above CSS hides content in desktop and mobile browsers wrapped with this class, but is seen by a screen reader like JAWS: http://www.freedomscientific.com/Products/Blindness/JAWS. Example markup is as follows:
<a href="#" target="_blank">
Click to Open Site
<span class="sr-only">This is an external link</span>
</a>
Additionally, if a DOM element has a width and height of 0, the element is not seen by the DOM. This is why the above CSS uses width: 1px; height: 1px;
. By using display: none
and setting your CSS to height: 0
and width: 0
, the element is not seen by the DOM and is thus problematic. The above CSS using width: 1px; height: 1px;
is not all you do to make the content invisible to desktop and mobile browsers (without overflow: hidden
, your content would still show on the screen), and visible to screen readers. Hiding the content from desktop and mobile browsers is done by adding an offset from width: 1px
and height: 1px
previously mentioned by using:
position: absolute;
margin: -1px 0 0 -1px;
overflow: hidden;
Lastly, to have a very good idea of what a screen reader sees and relays to its impaired user, turn off page styling for your browser. For Firefox, you can do this by going to:
View > Page Style > No Style
I hope the information I provided here is of further use to someone in addition to the other responses.
If you're using it in several different places, you should turn it into a plugin.
jQuery.fn.fadeOutAndRemove = function(speed){
$(this).fadeOut(speed,function(){
$(this).remove();
})
}
And then:
// Somewhere in the program code.
$('div').fadeOutAndRemove('fast');
Use PREPARE
/EXECUTE
and querying the schema.
The host doesn't need to have permission to create or run procedures :
SET @dbname = DATABASE();
SET @tablename = "tableName";
SET @columnname = "colName";
SET @preparedStatement = (SELECT IF(
(
SELECT COUNT(*) FROM INFORMATION_SCHEMA.COLUMNS
WHERE
(table_name = @tablename)
AND (table_schema = @dbname)
AND (column_name = @columnname)
) > 0,
"SELECT 1",
CONCAT("ALTER TABLE ", @tablename, " ADD ", @columnname, " INT(11);")
));
PREPARE alterIfNotExists FROM @preparedStatement;
EXECUTE alterIfNotExists;
DEALLOCATE PREPARE alterIfNotExists;
I find it more convenient to use something like the following:
document.querySelector('*').addEventListener('click',function(event){
if( event.target.tagName != "IMG"){
return;
}
// HANDLE CLICK ON IMAGES HERE
});
Update 1: It is possible for different users to have different path. But its not the likely problem here. There is more chance that the user that the iwam user doesn't have permission to the oracle client directory.
Update 0: Its suppose to work. Check for environment variable ( That are needed to find the oracle client and tnsnames.ora ). Also, Maybe you have a 32/64 bit issues. Also, consider using the Oracle Data Provider for .NET ( search for odp.net)
Use Assembly.GetTypes
. For example:
Assembly mscorlib = typeof(string).Assembly;
foreach (Type type in mscorlib.GetTypes())
{
Console.WriteLine(type.FullName);
}
An object technically is a dictionary.
var myMappings = {
mykey1: 'myValue',
mykey2: 'myValue'
};
var myVal = myMappings['myKey1'];
alert(myVal); // myValue
You can even loop through one.
for(var key in myMappings) {
var myVal = myMappings[key];
alert(myVal);
}
There is no reason whatsoever to reinvent the wheel. And of course, assignment goes like:
myMappings['mykey3'] = 'my value';
And ContainsKey:
if (myMappings.hasOwnProperty('myKey3')) {
alert('key already exists!');
}
I suggest you follow this: http://javascriptissexy.com/how-to-learn-javascript-properly/
Youre looking for the builtin function zip.
Simply copy the entire working directory contents (including the hidden .git
directory). This will move the entire working directory to the new directory and will not affect the remote repository on GitHub.
If you are using GitHub for Windows, you may move the repository using the method as above. However, when you click on the repository in the application it will be unable to find it. To resolve this simply click on the blue circle with the !, select Find It and then browse to the new directory.
you are missing () on the end of ToString.
After lot of struggle finally got it working. ( Perfectly tested)
The below example will also support the fact that color of already clicked button should not be changes
JQuery Code
var flag = 0; // Flag is to check if you are hovering on already clicked item
$("a").click(function() {
$('a').removeClass("YourColorClass");
$(this).addClass("YourColorClass");
flag=1;
});
$("a").mouseover(function() {
if ($(this).hasClass("YourColorClass")) {
flag=1;
}
else{
$(this).addClass("YourColorClass");
};
});
$("a").mouseout(function() {
if (flag == 0) {
$(this).removeClass("YourColorClass");
}
else{
flag = 0;
}
});
A simple (but maybe flawed) way that works in Python 2 and 3:
import time
import datetime
def utc_to_local(dt):
return dt - datetime.timedelta(seconds = time.timezone)
Its advantage is that it's trivial to write an inverse function
This is a simple way from XML only
spanCount for number of columns
layoutManager for making it grid or linear(Vertical or Horizontal)
<androidx.recyclerview.widget.RecyclerView
android:id="@+id/personListRecyclerView"
android:layout_width="0dp"
android:layout_height="0dp"
app:layoutManager="androidx.recyclerview.widget.GridLayoutManager"
app:spanCount="2"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintHorizontal_bias="0.5"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
object.sendKeys("your message", Keys.ENTER);
It works.

PDF.js is an HTML5 technology experiment that explores building a faithful and efficient Portable Document Format (PDF) renderer without native code assistance. It is community-driven and supported by Mozilla Labs.
You can see the demo here.
Another potential cause is that docker will not follow symbolic links by default (i.e don't use ln -s
).
or you could use this line:
link.setAttribute('onClick', 'onClickLink('+i+')');
instead of this one:
link.onclick= function() { onClickLink(i+'');};
Did the same thing for another quetion here

I must clarify that no-cache
does not mean do not cache. In fact, it means "revalidate with server" before using any cached response you may have, on every request.
must-revalidate
, on the other hand, only needs to revalidate when the resource is considered stale.
If the server says that the resource is still valid then the cache can respond with its representation, thus alleviating the need for the server to resend the entire resource.
no-store
is effectively the full do not cache directive and is intended to prevent storage of the representation in any form of cache whatsoever.
I say whatsoever, but note this in the RFC 2616 HTTP spec:
History buffers MAY store such responses as part of their normal operation
But this is omitted from the newer RFC 7234 HTTP spec in potentially an attempt to make no-store
stronger, see:
How about

Like the other answer says, in the left hand side select Products and add product. Then select Facbook Login.
I then added http://localhost:3000/ to the field 'Valid OAuth redirect URIs', and then everything worked.
If you wirte to a .csv file in C++ - you should use the syntax of :
myfile <<" %s; %s; %d", string1, string2, double1 <<endl;
This will write the three variables (string 1&2 and double1) into separate columns and leave an empty row below them. In excel the ; means the new row, so if you want to just take a new row - you can alos write a simple ";" before writing your new data into the file. If you don't want to have an empty row below - you should delete the endl and use the:
myfile.open("result.csv", std::ios::out | std::ios::app);
syntax when opening the .csv file (example the result.csv). In this way next time you write something into your result.csv file - it will write it into a new row directly below the last one - so you can easily manage a for cycle if you would like to.
You can also add hash when page is loading:
location.hash = "noBack";
Then just handle location hash change to add another hash:
$(window).on('hashchange', function() {
location.hash = "noBack";
});
That makes hash always present and back button tries to remove hash at first. Hash is then added again by "hashchange" handler - so page would never actually can be changed to previous one.

I've had similar requirements as described in the question and it took a while to figure things out based on existing answers, so I would like to share my final solution.
Requirements
The state of my view (component, technically) can be changed by the user (filter settings, sorting options, etc.) When state changes happen, i.e. the user changes the sorting direction, I want to:
additionally, I would like to:
Solution: Change state without reloading component
A state change does not cause a component reload when using route parameters or query parameters. The component instance stays alive. I see no good reason to mess with the router state by using Location.go()
or location.replaceState()
.
var state = { q: 'foo', sort: 'bar' };
var url = this.router.createUrlTree([], { relativeTo: this.activatedRoute, queryParams: state }).toString();
this.router.navigateByUrl(url);
The state
object will be transformed to URL query params by Angular's Router
:
https://localhost/some/route?q=foo&sort=bar
Solution: Handling state changes to make API calls
The state changes triggered above can be handled by subscribing to ActivatedRoute.queryParams
:
export class MyComponent implements OnInit {
constructor(private activatedRoute: ActivatedRoute) { }
ngOnInit()
{
this.activatedRoute.queryParams.subscribe((params) => {
// params is the state object passed to the router on navigation
// Make API calls here
});
}
}
The state
object of the above axample will be passed as the params
argument of the queryParams
observable. In the handler API calls can be made if necessary.
But: I would prefer handling the state changes directly in my component and avoid the detour over ActivatedRoute.queryParams
. IMO, navigating the router, letting Angular do routing magic and handle the queryParams
change to do something, completely obfuscates whats happening in my component with regards to maintenability and readability of my code. What I do instead:
Compare the state passed in to queryParams
observable with the current state in my component, do nothing, if it hasn't changed there and handle state changes directly instead:
export class MyComponent implements OnInit {
private _currentState;
constructor(private activatedRoute: ActivatedRoute) { }
ngOnInit()
{
this.activatedRoute.queryParams.subscribe((params) => {
// Following comparison assumes, that property order doesn't change
if (JSON.stringify(this._currentState) == JSON.stringify(params)) return;
// The followig code will be executed only when the state changes externally, i.e. through navigating to a URL with params by the user
this._currentState = params;
this.makeApiCalls();
});
}
updateView()
{
this.makeApiCalls();
this.updateUri();
}
updateUri()
{
var url = this.router.createUrlTree([], { relativeTo: this.activatedRoute, queryParams: this._currentState }).toString();
this.router.navigateByUrl(url);
}
}
Solution: Specify browser history behavior
var createHistoryEntry = true // or false
var url = ... // see above
this.router.navigateByUrl(url, { replaceUrl : !createHistoryEntry});
Solution: Complex objects as state
This is beyond the original question but adresses common scenarios and might thus be useful: The state
object above is limited to flat objects (an object with only simple string/bool/int/... properties but no nested objects). I found this limiting, because I need to distinguish between properties that need to be handled with a backend call and others, that are only used by the component internally. I wanted a state object like:
var state = { filter: { something: '', foo: 'bar' }, viewSettings: { ... } };
To use this state as queryParams object for the router, it needs to be flattened. I simply JSON.stringify
all first level properties of the object:
private convertToParamsData(data) {
var params = {};
for (var prop in data) {
if (Object.prototype.hasOwnProperty.call(data, prop)) {
var value = data[prop];
if (value == null || value == undefined) continue;
params[prop] = JSON.stringify(value, (k, v) => {
if (v !== null) return v
});
}
}
return params;
}
and back, when handling the queryParams returned passed in by the router:
private convertFromParamsData(params) {
var data = {};
for (var prop in params) {
if (Object.prototype.hasOwnProperty.call(params, prop)) {
data[prop] = JSON.parse(params[prop]);
}
}
return data;
}
Finally: A ready-to-use Angular service
And finally, all of this isolated in one simple service:
import { Injectable } from '@angular/core';
import { ActivatedRoute, Router } from '@angular/router';
import { Observable } from 'rxjs';
import { Location } from '@angular/common';
import { map, filter, tap } from 'rxjs/operators';
@Injectable()
export class QueryParamsService {
private currentParams: any;
externalStateChange: Observable<any>;
constructor(private activatedRoute: ActivatedRoute, private router: Router, private location: Location) {
this.externalStateChange = this.activatedRoute.queryParams
.pipe(map((flatParams) => {
var params = this.convertFromParamsData(flatParams);
return params
}))
.pipe(filter((params) => {
return !this.equalsCurrentParams(params);
}))
.pipe(tap((params) => {
this.currentParams = params;
}));
}
setState(data: any, createHistoryEntry = false) {
var flat = this.convertToParamsData(data);
const url = this.router.createUrlTree([], { relativeTo: this.activatedRoute, queryParams: flat }).toString();
this.currentParams = data;
this.router.navigateByUrl(url, { replaceUrl: !createHistoryEntry });
}
private equalsCurrentParams(data) {
var isEqual = JSON.stringify(data) == JSON.stringify(this.currentParams);
return isEqual;
}
private convertToParamsData(data) {
var params = {};
for (var prop in data) {
if (Object.prototype.hasOwnProperty.call(data, prop)) {
var value = data[prop];
if (value == null || value == undefined) continue;
params[prop] = JSON.stringify(value, (k, v) => {
if (v !== null) return v
});
}
}
return params;
}
private convertFromParamsData(params) {
var data = {};
for (var prop in params) {
if (Object.prototype.hasOwnProperty.call(params, prop)) {
data[prop] = JSON.parse(params[prop]);
}
}
return data;
}
}
which can be used like:
@Component({
selector: "app-search",
templateUrl: "./search.component.html",
styleUrls: ["./search.component.scss"],
providers: [QueryParamsService]
})
export class ProjectSearchComponent implements OnInit {
filter : any;
viewSettings : any;
constructor(private queryParamsService: QueryParamsService) { }
ngOnInit(): void {
this.queryParamsService.externalStateChange
.pipe(debounce(() => interval(500))) // Debounce optional
.subscribe(params => {
// Set state from params, i.e.
if (params.filter) this.filter = params.filter;
if (params.viewSettings) this.viewSettings = params.viewSettings;
// You might want to init this.filter, ... with default values here
// If you want to write default values to URL, you can call setState here
this.queryParamsService.setState(params, false); // false = no history entry
this.initializeView(); //i.e. make API calls
});
}
updateView() {
var data = {
filter: this.filter,
viewSettings: this.viewSettings
};
this.queryParamsService.setState(data, true);
// Do whatever to update your view
}
// ...
}
Don't forget the providers: [QueryParamsService]
statement on component level to create a new service instance for the component. Don't register the service globally on app module.
I just read the source code for ImageView
and it is basically impossible without using the subclassing solutions in this thread. In ImageView.onMeasure
we get to these lines:
// Get the max possible width given our constraints
widthSize = resolveAdjustedSize(w + pleft + pright, mMaxWidth, widthMeasureSpec);
// Get the max possible height given our constraints
heightSize = resolveAdjustedSize(h + ptop + pbottom, mMaxHeight, heightMeasureSpec);
Where h
and w
are the dimensions of the image, and p*
is the padding.
And then:
private int resolveAdjustedSize(int desiredSize, int maxSize,
int measureSpec) {
...
switch (specMode) {
case MeasureSpec.UNSPECIFIED:
/* Parent says we can be as big as we want. Just don't be larger
than max size imposed on ourselves.
*/
result = Math.min(desiredSize, maxSize);
So if you have a layout_height="wrap_content"
it will set widthSize = w + pleft + pright
, or in other words, the maximum width is equal to the image width.
This means that unless you set an exact size, images are NEVER enlarged. I consider this to be a bug, but good luck getting Google to take notice or fix it. Edit: Eating my own words, I submitted a bug report and they say it has been fixed in a future release!
Here is another subclassed workaround, but you should (in theory, I haven't really tested it much!) be able to use it anywhere you ImageView
. To use it set layout_width="match_parent"
, and layout_height="wrap_content"
. It is quite a lot more general than the accepted solution too. E.g. you can do fit-to-height as well as fit-to-width.
import android.content.Context;

return;

int w = getDrawable().getIntrinsicWidth();

if (w <= 0)
w = 1;
if (h <= 0)
h = 1;
// Desired aspect ratio of the view's contents (not including padding)
float desiredAspect = (float) w / (float) h;
// We are allowed to change the view's width
boolean resizeWidth = widthSpecMode != MeasureSpec.EXACTLY;

boolean resizeHeight = heightSpecMode != MeasureSpec.EXACTLY;
int pleft = getPaddingLeft();
int pright = getPaddingRight();

// Get the sizes that ImageView decided on.

int heightSize = getMeasuredHeight();
if (resizeWidth && !resizeHeight)
{
// Resize the width to the height, maintaining aspect ratio.
int newWidth = (int) (desiredAspect * (heightSize - ptop - pbottom)) + pleft + pright;
setMeasuredDimension(newWidth, heightSize);
}
else if (resizeHeight && !resizeWidth)
{
int newHeight = (int) ((widthSize - pleft - pright) / desiredAspect) + ptop + pbottom;
setMeasuredDimension(widthSize, newHeight);
}
}
}

This is because Java Generics are implemented with Type Erasure.
Your methods would be translated, at compile time, to something like:
Method resolution occurs at compile time and doesn't consider type parameters. (see erickson's answer)
void add(Set ii);
void add(Set ss);
Both methods have the same signature without the type parameters, hence the error.
From Visual Studio 2013
onwards, MSbuild
comes as a part of Visual Studio. Earlier, MSBuild was installed as a part of. NET Framework.
MSBuild is installed directly under %ProgramFiles%. So, the path for MSBuild might be different depending on the version of Visual Studio.
For Visual Studio 2015
, Path of MSBuild
is "%ProgramFiles(x86)%\MSBuild\14.0\Bin\MSBuild.exe"
For Visual Studio 15 Preview
, Path of MSBuild
is "%ProgramFiles(x86)%\MSBuild\15.0\Bin\MSBuild.exe"
Also, Some new MSBuild properties has been added and some have been modified. For more information look here
Update 1: VS 2017
The location for the MSBuild has changed again with the release of Visual Studio 2017. Now the installation directory is under the %ProgramFiles(x86)%\Microsoft Visual Studio\2017\[VS Edition]\MSBuild\15.0\Bin\
. Since, i have an Enterprise edition, the MSBuild location for my machine is "%ProgramFiles(x86)%\Microsoft Visual Studio\2017\Enterprise\MSBuild\15.0\Bin\MSbuild.exe"
Think in the inverse way: how to make the 2 ranges not overlap? Given [x1, x2]
, then [y1, y2]
should be outside [x1, x2]
, i.e., y1 < y2 < x1 or x2 < y1 < y2
which is equivalent to y2 < x1 or x2 < y1
.
Therefore, the condition to make the 2 ranges overlap: not(y2 < x1 or x2 < y1)
, which is equivalent to y2 >= x1 and x2 >= y1
(same with the accepted answer by Simon).
Have read the documentation you've linked. That's totally silly! xclip
is just a clipboard. You'll find other ways to copy paste the key... (I'm sure)
If you aren't working from inside a graphical X session you need to pass the $DISPLAY
environment var to the command. Run it like this:
DISPLAY=:0 xclip -sel clip < ~/.ssh/id_rsa.pub
Of course :0
depends on the display you are using. If you have a typical desktop machine it is likely that it is :0

Ultimately you always have a finite max of heap to use no matter what platform you are running on. In Windows 32 bit this is around 2GB
(not specifically heap but total amount of memory per process). It just happens that Java chooses to make the default smaller (presumably so that the programmer can't create programs that have runaway memory allocation without running into this problem and having to examine exactly what they are doing).
So this given there are several approaches you could take to either determine what amount of memory you need or to reduce the amount of memory you are using. One common mistake with garbage collected languages such as Java or C# is to keep around references to objects that you no longer are using, or allocating many objects when you could reuse them instead. As long as objects have a reference to them they will continue to use heap space as the garbage collector will not delete them.
In this case you can use a Java memory profiler to determine what methods in your program are allocating large number of objects and then determine if there is a way to make sure they are no longer referenced, or to not allocate them in the first place. One option which I have used in the past is "JMP" http://www.khelekore.org/jmp/.
If you determine that you are allocating these objects for a reason and you need to keep around references (depending on what you are doing this might be the case), you will just need to increase the max heap size when you start the program. However, once you do the memory profiling and understand how your objects are getting allocated you should have a better idea about how much memory you need.
In general if you can't guarantee that your program will run in some finite amount of memory (perhaps depending on input size) you will always run into this problem. Only after exhausting all of this will you need to look into caching objects out to disk etc. At this point you should have a very good reason to say "I need Xgb of memory" for something and you can't work around it by improving your algorithms or memory allocation patterns. Generally this will only usually be the case for algorithms operating on large datasets (like a database or some scientific analysis program) and then techniques like caching and memory mapped IO become useful.
Today we use Bearer token
more often that Basic Authentication
but if you want to have Basic Authentication
first to get Bearer token then there is a couple ways:
const request = new XMLHttpRequest();
request.open('GET', url, false, username,password)
request.onreadystatechange = function() {
// D some business logics here if you receive return
if(request.readyState === 4 && request.status === 200) {
console.log(request.responseText);
}
}
request.send()
Full syntax is here
Second Approach using Ajax:
$.ajax
({
type: "GET",
url: "abc.xyz",
dataType: 'json',
async: false,
username: "username",
password: "password",
data: '{ "key":"sample" }',
success: function (){
alert('Thanks for your up vote!');
}
});
Hopefully, this provides you a hint where to start API calls with JS. In Frameworks like Angular, React, etc there are more powerful ways to make API call with Basic Authentication
or Oauth Authentication
. Just explore it.
Try this
<input onclick="confirmSubmit(event);" type="button" value="Send" />
Along with this
function confirmSubmit(event){
var domElement =$(event.target);
console.log(domElement.attr('type'));
}
I tried it in firefox, it prints the 'type' attribute of dom Element clicked. I guess you can then get the form via the parents() methods using this object.
myTextBox.addTextChangedListener(new TextWatcher() {
public void afterTextChanged(Editable s) {}
public void beforeTextChanged(CharSequence s, int start, int count, int after) {}
public void onTextChanged(CharSequence s, int start, int before, int count) {
TextView myOutputBox = (TextView) findViewById(R.id.myOutputBox);
myOutputBox.setText(s);
}
});
We can use replace
to change the values in 'mpg' to NA
that corresponds to cyl==4
.
mtcars %>%
mutate(mpg=replace(mpg, cyl==4, NA)) %>%
as.data.frame()
Add an onchange event handler and set the pages location to the value
<select id="foo">
<option value="">Pick a site</option>
<option value="http://www.google.com">x</option>
<option value="http://www.yahoo.com">y</option>
</select>
<script>
document.getElementById("foo").onchange = function() {
if (this.selectedIndex!==0) {
window.location.href = this.value;
}
};
</script>
I've got this solution.
Get the id of the commit where the file was deleted using one of the ways below.
git log --grep=*word*

# recommended if you hardly
remember anythingYou should get something like:
commit bfe68bd117e1091c96d2976c99b3bcc8310bebe7 Author: Alexander Orlov Date: Thu May 12 23:44:27 2011 +0200

3. Now using the commit id bfe68bd117e1091c96d2976c99b3bcc8310bebe7 do:
git checkout bfe68bd117e1091c96d2976c99b3bcc8310bebe7^1 yourDeletedFile.java
As the commit id references the commit where the file was already deleted you need to reference the commit just before bfe68b which you can do by appending ^1
. This means: give me the commit just before bfe68b.
href
is optional for a
elements.
It's completely sufficient to use
<a onclick="ShowOld(2367,146986,2)">link text</a>
Java 8
If you are using Java 8 in your project and comparing java.sql.Timestamp
, you could use the LocalDate
class:
sameDate = date1.toLocalDateTime().toLocalDate().equals(date2.toLocalDateTime().toLocalDate());
If you are using java.util.Date
, have a look at Istvan answer which is less ambiguous.
As the error says your router link should match the existing routes configured

What it correct way of installing SmartGit on Ubuntu? Thus I can have normal icon
In smartgit/bin folder, there's a shell script waiting for you: add-menuitem.sh. It does just that.
If you want to match the two words in either order, use:
gci C:\Logs| select-string -pattern '(VendorEnquiry.*Failed)|(Failed.*VendorEnquiry)'
If Failed always comes after VendorEnquiry on the line, just use:
gci C:\Logs| select-string -pattern '(VendorEnquiry.*Failed)'

Static libraries are archives that contain the object code for the library, when linked into an application that code is compiled into the executable. Shared libraries are different in that they aren't compiled into the executable. Instead the dynamic linker searches some directories looking for the library(s) it needs, then loads that into memory. More then one executable can use the same shared library at the same time, thus reducing memory usage and executable size. However, there are then more files to distribute with the executable. You need to make sure that the library is installed onto the uses system somewhere where the linker can find it, static linking eliminates this problem but results in a larger executable file.
I don't believe MySQL supports dynamic sql. You can do "prepared" statements which is similar, but different.
Here is an example:
mysql> PREPARE stmt FROM
-> 'select count(*)
-> from information_schema.schemata
-> where schema_name = ? or schema_name = ?'
;
Query OK, 0 rows affected (0.00 sec)
Statement prepared
mysql> EXECUTE stmt
-> USING @schema1,@schema2
+----------+
| count(*) |
+----------+
| 2 |
+----------+
1 row in set (0.00 sec)
mysql> DEALLOCATE PREPARE stmt;
The prepared statements are often used to see an execution plan for a given query. Since they are executed with the execute command and the sql can be assigned to a variable you can approximate the some of the same behavior as dynamic sql.
Here is a good link about this:
Don't forget to deallocate the stmt
using the last line!
Good Luck!
I would first try resetting all Visual Studio settings (Tools > Import and Export Settings > Reset all settings), then go to the Resharper > Options > Keyboard & Menus and re-apply the keyboard shortcut scheme.
I had to do something similar once.
I found Serge's answer to be very promising, but I also encountered performance issues with it as-written. However, when I restructured it to use temporary tables and not include double CTE tables, the performance went from 1 minute 40 seconds to sub-second for 1000 combined records. Here it is for anyone who needs to do this without FOR XML on older versions of SQL Server:
DECLARE @STRUCTURED_VALUES TABLE (
ID INT
,VALUE VARCHAR(MAX) NULL
,VALUENUMBER BIGINT
,VALUECOUNT INT
);
INSERT INTO @STRUCTURED_VALUES
SELECT ID
,VALUE
,ROW_NUMBER() OVER (PARTITION BY ID ORDER BY VALUE) AS VALUENUMBER
,COUNT(*) OVER (PARTITION BY ID) AS VALUECOUNT
FROM RAW_VALUES_TABLE;
WITH CTE AS (
SELECT SV.ID
,SV.VALUE
,SV.VALUENUMBER
,SV.VALUECOUNT
FROM @STRUCTURED_VALUES SV
WHERE VALUENUMBER = 1
UNION ALL
SELECT SV.ID
,CTE.VALUE + ' ' + SV.VALUE AS VALUE
,SV.VALUENUMBER
,SV.VALUECOUNT
FROM @STRUCTURED_VALUES SV
JOIN CTE
ON SV.ID = CTE.ID
AND SV.VALUENUMBER = CTE.VALUENUMBER + 1
)
SELECT ID
,VALUE
FROM CTE
WHERE VALUENUMBER = VALUECOUNT
ORDER BY ID
;
When your browser redirects the user to Google's oAuth page, are you passing as a parameter the redirect URI you want Google's server to return to with the token response? Setting a redirect URI in the console is not a way of telling Google where to go when a login attempt comes in, but rather it's a way of telling Google what the allowed redirect URIs are (so if someone else writes a web app with your client ID but a different redirect URI it will be disallowed); your web app should, when someone clicks the "login" button, send the browser to:
https://accounts.google.com/o/oauth2/auth?client_id=XXXXX&redirect_uri=http://localhost:8080/WEBAPP/youtube-callback.html&response_type=code&scope=https://www.googleapis.com/auth/youtube.upload
(the callback URI passed as a parameter must be url-encoded, btw).
When Google's server gets authorization from the user, then, it'll redirect the browser to whatever you sent in as the redirect_uri
. It'll include in that request the token as a parameter, so your callback page can then validate the token, get an access token, and move on to the other parts of your app.
If you visit:
http://code.google.com/p/google-api-java-client/wiki/OAuth2#Authorization_Code_Flow
You can see better samples of the java client there, demonstrating that you have to override the getRedirectUri
method to specify your callback path so the default isn't used.
The redirect URIs are in the client_secrets.json
file for multiple reasons ... one big one is so that the oAuth flow can verify that the redirect your app specifies matches what your app allows.
If you visit https://developers.google.com/api-client-library/java/apis/youtube/v3 You can generate a sample application for yourself that's based directly off your app in the console, in which (again) the getRedirectUri method is overwritten to use your specific callbacks.
All radio buttons have to have the same name:
<input type='radio' name='foo'>
Only 1 radio button of each group of buttons with the same name can be checked.
jww is right — you're referencing the wrong intermediate certificate.
As you have been issued with a SHA256 certificate, you will need the SHA256 intermediate. You can grab it from here: http://secure2.alphassl.com/cacert/gsalphasha2g2r1.crt
As Cubbi pointed out in one of the comments, std::wstring_convert
(C++11) provides a neat simple solution (you need to #include
<locale>
and <codecvt>
):
std::wstring string_to_convert;
//setup converter
using convert_type = std::codecvt_utf8<wchar_t>;
std::wstring_convert<convert_type, wchar_t> converter;
//use converter (.to_bytes: wstr->str, .from_bytes: str->wstr)
std::string converted_str = converter.to_bytes( string_to_convert );
I was using a combination of wcstombs
and tedious allocation/deallocation of memory before I came across this.

One liners can be stated as so (Thank you Guss for your comment):
std::wstring str = std::wstring_convert<std::codecvt_utf8<wchar_t>>().from_bytes("some string");
Wrapper functions can be stated as so: (Thank you ArmanSchwarz for your comment)
std::wstring s2ws(const std::string& str)
{
using convert_typeX = std::codecvt_utf8<wchar_t>;
std::wstring_convert<convert_typeX, wchar_t> converterX;
return converterX.from_bytes(str);
}
std::string ws2s(const std::wstring& wstr)
{
using convert_typeX = std::codecvt_utf8<wchar_t>;
std::wstring_convert<convert_typeX, wchar_t> converterX;
return converterX.to_bytes(wstr);
}
Note: there's some controversy on whether string
/wstring
should be passed in to functions as references or as literals (due to C++11 and compiler updates). I'll leave the decision to the person implementing, but it's worth knowing.
Note: I'm using std::codecvt_utf8
in the above code, but if you're not using UTF-8 you'll need to change that to the appropriate encoding you're using:
As the documentation says, this method call returns "a pseudorandom, uniformly distributed int value between 0 (inclusive) and the specified value (exclusive)". This means that you will get numbers from 0 to 9 in your case. So you've done everything correctly by adding one to that number.
Generally speaking, if you need to generate numbers from min
to max
(including both), you write
random.nextInt(max - min + 1) + min
Is to do with IPv6

Some people have had issues with it, and disabled it, but as a general rule, if it aint broke...
You must perform a terminal operation on the Stream in order for any of the filters to be applied. Therefore you can't know if it will be empty until you consume it.
Best you can do is terminate the Stream with a findAny()
terminal operation, which will stop when it finds any element, but if there are none, it will have to iterate over all the input list to find that out.
This would only help you if the input list has many elements, and one of the first few passes the filters, since only a small subset of the list would have to be consumed before you know the Stream is not empty.
Of course you'll still have to create a new Stream in order to produce the output list.
It is always better if things are automated.That's why I wrote simple python script for copying db file from device using ADB. It saves a lot of development time if you're doing it frequently.
Works only with debuggable apps if device is Not rooted.
Run it as : python copyandroiddbfile.py

import subprocess

# 1. Python script which will copy database file of debuggable apps from the android device to your computer using ADB.
# 2. This script ask for PackageName and DatabaseName at runtime.
# 3. You can make it static by passing -d at as command line argument while running script and setting defaults in following way.
# 4. Edit script and change the values of varialbe packageName and dbName to debuggable app package name and database name then
# run script as : python Copydbfileandroid.py -d

There is no difference between the two, one is just a shorthand for the second.
The v- prefix serves as a visual cue for identifying Vue-specific attributes in your templates. This is useful when you are using Vue.js to apply dynamic behavior to some existing markup, but can feel verbose for some frequently used directives. At the same time, the need for the v- prefix becomes less important when you are building an SPA where Vue.js manages every template.

<a v-on:click="doSomething"></a>

By default, Elasticsearch installed goes into read-only mode when you have less than 5% of free disk space. If you see errors similar to this:
Elasticsearch::Transport::Transport::Errors::Forbidden: [403] {"error":{"root_cause":[{"type":"cluster_block_exception","reason":"blocked by: [FORBIDDEN/12/index read-only / allow delete (api)];"}],"type":"cluster_block_exception","reason":"blocked by: [FORBIDDEN/12/index read-only / allow delete (api)];"},"status":403}
Or in /usr/local/var/log/elasticsearch.log you can see logs similar to:
flood stage disk watermark [95%] exceeded on [nCxquc7PTxKvs6hLkfonvg][nCxquc7][/usr/local/var/lib/elasticsearch/nodes/0] free: 15.3gb[4.1%], all indices on this node will be marked read-only
Then you can fix it by running the following commands:
curl -XPUT -H "Content-Type: application/json" http://localhost:9200/_cluster/settings -d '{ "transient": { "cluster.routing.allocation.disk.threshold_enabled": false } }'
curl -XPUT -H "Content-Type: application/json" http://localhost:9200/_all/_settings -d '{"index.blocks.read_only_allow_delete": null}'
For all users on a specific database, do the following:
# psql
\c your_database
select grantee, table_catalog, privilege_type, table_schema, table_name from information_schema.table_privileges order by grantee, table_schema, table_name;
Much like the answer Matt Curtis gave, I set environment variables via launchctl, but I wrap it in a function called export, so that whenever I export a variable like normal in my .bash_profile, it is also set by launchctl. Here is what I do:
My .bash_profile consists solely of one line, (This is just personal preference.)
source .bashrc
My .bashrc has this:
function export()
{
builtin export "$@"
if [[ ${#@} -eq 1 && "${@//[^=]/}" ]]
then
launchctl setenv "${@%%=*}" "${@#*=}"
elif [[ ! "${@//[^ ]/}" ]]
then
launchctl setenv "${@}" "${!@}"
fi
}
export -f export
The above will overload the Bash builtin "export" and will export everything normally (you'll notice I export "export" with it!), then properly set them for OS X app environments via launchctl, whether you use any of the following:
export LC_CTYPE=en_US.UTF-8
# ~$ launchctl getenv LC_CTYPE
# en_US.UTF-8
PATH="/usr/local/bin:${PATH}"
PATH="/usr/local/opt/coreutils/libexec/gnubin:${PATH}"
export PATH
# ~$ launchctl getenv PATH
# /usr/local/opt/coreutils/libexec/gnubin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin
export CXX_FLAGS="-mmacosx-version-min=10.9"
# ~$ launchctl getenv CXX_FLAGS
# -mmacosx-version-min=10.9
This way I don't have to send every variable to launchctl every time, and I can just have my .bash_profile / .bashrc set up the way I want. Open a terminal window, check out your environment variables you're interested in with launchctl getenv myVar
, change something in your .bash_profile/.bashrc, close the terminal window and re-open it, check the variable again with launchctl, and voilá, it's changed.
Again, like the other solutions for the post-Mountain Lion world, for any new environment variables to be available for apps, you need to launch or re-launch them after the change.
if (+(/MSIE\s(\d+)/.exec(navigator.userAgent)||0)[1] < 9) {
// IE8 or less
}
/MSIE\s(\d+)/.exec(navigator.userAgent)
null
so in that case ||0
will switch that null
to 0
[1]
will get major version of IE or undefined
if it was not an IE browser+
will convert it into a number, undefined
will be converted to NaN
NaN
with a number will always return false
I found some of the solutions here to be slow and/or confusing (and some of them don't handle ties correctly) so I wrote my own data.table
based function auc_roc() in my R package mltools.
library(data.table)
library(mltools)
preds <- c(.1, .3, .3, .9)
actuals <- c(0, 0, 1, 1)
auc_roc(preds, actuals) # 0.875
auc_roc(preds, actuals, returnDT=TRUE)
Pred CountFalse CountTrue CumulativeFPR CumulativeTPR AdditionalArea CumulativeArea
1: 0.9 0 1 0.0 0.5 0.000 0.000
2: 0.3 1 1 0.5 1.0 0.375 0.375
3: 0.1 1 0 1.0 1.0 0.500 0.875
As described from other answers, but with steps:
1- go to control panel -> uninstall programs -> uninstall all Microsoft C++ ((year)) Redistributable
2- delete those files if they still exist manually:
3- download and install: https://www.microsoft.com/en-us/download/details.aspx?id=48145
after that rerun the installation of Visual Studio, and hope that error won't show again.
DataMember attribute is not mandatory to add to serialize data. When DataMember attribute is not added, old XMLSerializer serializes the data. Adding a DataMember provides useful properties like order, name, isrequired which cannot be used otherwise.
I'm sure there are other ways to accomplish this, but one solution would be to use join
through the Query Builder.
If you have tables set up something like this:
users
id
...
friends
id
user_id
friend_id
...
votes, comments and status_updates (3 tables)
id
user_id
....
In your User model:
class User extends Eloquent {
public function friends()
{
return $this->hasMany('Friend');
}
}
In your Friend model:
class Friend extends Eloquent {
public function user()
{
return $this->belongsTo('User');
}
}
Then, to gather all the votes for the friends of the user with the id of 1, you could run this query:
$user = User::find(1);
$friends_votes = $user->friends()
->with('user') // bring along details of the friend
->join('votes', 'votes.user_id', '=', 'friends.friend_id')
->get(['votes.*']); // exclude extra details from friends table
Run the same join
for the comments
and status_updates
tables. If you would like votes, comments, and status_updates to be in one chronological list, you can merge the resulting three collections into one and then sort the merged collection.
Edit
To get votes, comments, and status updates in one query, you could build up each query and then union the results. Unfortunately, this doesn't seem to work if we use the Eloquent hasMany
relationship (see comments for this question for a discussion of that problem) so we have to modify to queries to use where
instead:
$friends_votes =
DB::table('friends')->where('friends.user_id','1')
->join('votes', 'votes.user_id', '=', 'friends.friend_id');
$friends_comments =
DB::table('friends')->where('friends.user_id','1')
->join('comments', 'comments.user_id', '=', 'friends.friend_id');
$friends_status_updates =
DB::table('status_updates')->where('status_updates.user_id','1')
->join('friends', 'status_updates.user_id', '=', 'friends.friend_id');
$friends_events =
$friends_votes
->union($friends_comments)
->union($friends_status_updates)
->get();
At this point, though, our query is getting a bit hairy, so a polymorphic relationship with and an extra table (like DefiniteIntegral suggests below) might be a better idea.
For performance issue, first data is to be written into Buffer. When buffer get full then data is written to output (File,console etc.). When buffer is partially filled and you want to send it to output(file,console) then you need to call flush() method manually in order to write partially filled buffer to output(file,console).
given that you're a newbie, I'd say don't try to do this yet. it's definitely possible, but will needlessly complicate your Makefile. stick to the simple ways until you're more comfortable with make.
that said, one way to build in a directory different from the source directory is VPATH; i prefer pattern rules
