You need to use ScriptManager.RegisterStartupScript for Ajax.
protected void ButtonPP_Click(object sender, EventArgs e) { if (radioBtnACO.SelectedIndex < 0) { string csname1 = "PopupScript"; var cstext1 = new StringBuilder(); cstext1.Append("alert('Please Select Criteria!')"); ScriptManager.RegisterStartupScript(this, GetType(), csname1, cstext1.ToString(), true); } }
You should use parameters in your query to prevent attacks, like if someone entered '); drop table ArticlesTBL;--'
as one of the values.
string query = "INSERT INTO ArticlesTBL (ArticleTitle, ArticleContent, ArticleType, ArticleImg, ArticleBrief, ArticleDateTime, ArticleAuthor, ArticlePublished, ArticleHomeDisplay, ArticleViews)";
query += " VALUES (@ArticleTitle, @ArticleContent, @ArticleType, @ArticleImg, @ArticleBrief, @ArticleDateTime, @ArticleAuthor, @ArticlePublished, @ArticleHomeDisplay, @ArticleViews)";
SqlCommand myCommand = new SqlCommand(query, myConnection);
myCommand.Parameters.AddWithValue("@ArticleTitle", ArticleTitleTextBox.Text);
myCommand.Parameters.AddWithValue("@ArticleContent", ArticleContentTextBox.Text);
// ... other parameters
myCommand.ExecuteNonQuery();
It looks like window.open
will take a Data URI as the location parameter.
So you can open it like this from the question: Opening PDF String in new window with javascript:
window.open("data:application/pdf;base64, " + base64EncodedPDF);
Here's an runnable example in plunker, and sample pdf file that's already base64 encoded.
Then on the server, you can convert the byte array to base64 encoding like this:
string fileName = @"C:\TEMP\TEST.pdf";
byte[] pdfByteArray = System.IO.File.ReadAllBytes(fileName);
string base64EncodedPDF = System.Convert.ToBase64String(pdfByteArray);
NOTE: This seems difficult to implement in IE because the URL length is prohibitively small for sending an entire PDF.
This works for me. Hope it will work for you too.
ScriptManager.RegisterStartupScript(this, this.GetType(), "isActive", "Test();", true);
I have edited the html page which you have provided. The updated page is as below
<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1" runat="server">
<title>My Page</title>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js" type="text/javascript"></script>
<script type="text/javascript">
function Test() {
alert("Hello Test!!!!");
$('#ButtonRow').css("display", "block");
}
</script>
</head>
<body>
<form id="form1" runat="server">
<table>
<tr>

<asp:RadioButtonList ID="SearchCategory" runat="server" RepeatDirection="Horizontal"
BorderStyle="Solid">
<asp:ListItem>Merchant</asp:ListItem>
<asp:ListItem>Store</asp:ListItem>
<asp:ListItem>Terminal</asp:ListItem>
</asp:RadioButtonList>
</td>
</tr>
<tr id="ButtonRow" style="display: none">
<td>
<asp:Button ID="MyButton" runat="server" Text="Click Here" OnClick="MyButton_Click" />
</td>
</tr>
</table>
</form>
</body>
</html>
<script type="text/javascript">
$("#<%=SearchCategory.ClientID%> input").change(function () {
alert("hi");
$("#ButtonRow").show();
});
</script>
Use:
Target= "_blank" property of anchor tag
A POSIX compliant one using the s
command:
sed '/CLIENTSCRIPT="foo"/s/.*/&\
CLIENTSCRIPT2="hello"/' file
As Dennis says, you can't control how the browser chooses to handle target=_blank.
If you're wondering about the inconsistent behavior, probably it's pop-up blocking. Many browsers will forbid new windows from being opened apropos of nothing, but will allow new windows to be spawned as the eventual result of a mouse-click event.
Or write to the response stream:
Response.Write("<script>");
Response.Write("window.open('page.html','_blank')");
Response.Write("</script>");
Is Button1
visible? I mean, from the server side. Make sure Button1.Visible is true.
Controls that aren't Visible
won't be rendered in HTML, so although they are assigned a ClientID
, they don't actually exist on the client side.
If you look at the first lines of text you can glean what your error is.
this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them
You're dynamically editing the lstProblems dropdown, so when you post back ASP.NET says "Warning! Invalid entries in the dropdown!" and freaks out throwing that error. You have to determine if turning off event validation is an OK solution, but I would research it before doing it, since the idea behind it is to make your site more secure for free.
Here's another stackoverflow answer that does a much better job explaining what to do than me: Invalid postback or callback argument. Event validation is enabled using '<pages enableEventValidation="true"/>'
string textboxID;
string da;
textboxID = "ctl00$MainContent$grd$ctl" + (grd.Columns.Count + j).ToString() + "$txtDyna" + (k).ToString();
textboxID= ctl00$MainContent$grd$ctl12$ctl00;
da = Request.Form(textboxID);
I use this and it works, as long as the page is not redirect afterwards. Would be nice to have it show, and wait until the user clicks OK, regardless of redirects.

Where str

Here is what you can do using jquery:
$('#A_ID').click(function (e) { //#A_ID is an example. Use the id of your Anchor
$('html, body').animate({
scrollTop: $('#DIV_ID').offset().top - 20 //#DIV_ID is an example. Use the id of your destination on the page
}, 'slow');
});
Hai sridhar, I found an answer for your prob
ClientScript.RegisterClientScriptBlock(GetType(), "sas", "<script> alert('Inserted successfully');</script>", true);
change false to true
or try this
ScriptManager.RegisterClientScriptBlock(ursavebuttonID, typeof(LinkButton or button), "sas", "<script> alert('Inserted successfully');</script>", true);
There are a few ways to handle rendering/showing controls on the page and you should take note to what happens with each method.
Rendering and Visibility
There are some instances where elements on your page don't need to be rendered for the user because of some type of logic or database value. In this case, you can prevent rendering (creating the control on the returned web page) altogether. You would want to do this if the control doesn't need to be shown later on the client side because no matter what, the user viewing the page never needs to see it.
Any controls or elements can have their visibility set from the server side. If it is a plain old html element, you just need to set the runat
attribute value to server
on the markup page.
<div id="myDiv" runat="server"></div>
The decision to render the div or not can now be done in the code behind class like so:
myDiv.Visible = someConditionalBool;
If set to true, it will be rendered on the page and if it's false it won't be rendered at all, not even hidden.
Client Side Hiding
Hiding an element is done on the client side only. Meaning, it's rendered but it has a display
CSS style set on it which instructs your browser to not show it to the user. This is beneficial when you want to hide/show things based on user input. It's important to know that the element CAN be hidden on the server side too as long as the element/control has runat=server
set just as I explained in the previous example.
Hiding in the Code Behind Class
To hide an element that you want rendered to the page but hidden is another simple single line of code:
myDiv.Style["display"] = "none";
If you have a need to remove the display
style server side, it can be done by removing the display
style, or setting it to a different value like inline
or block
(values described here).
myDiv.Style.Remove("display");
// -- or --
myDiv.Style["display"] = "inline";
Hiding on the Client Side with javascript
Using plain old javascript, you can easily hide the same element in this manner
var myDivElem = document.getElementById("myDiv");
myDivElem.style.display = "none";
// then to show again
myDivElem.style.display = "";
jQuery makes hiding elements a little simpler if you prefer to use jQuery:
var myDiv = $("#<%=myDiv.ClientID%>");
myDiv.hide();
// ... and to show
myDiv.show();
You can try the Anthem library.
Also check that you are not using validation groups as that validation wouldnt fire if the validationgroup property was set and not explicitly called via
Page.Validate({Insert validation group name here});
Here's an old discussion thread where I listed the main differences and the conditions in which you should use each of these methods. I think you may find it useful to go through the discussion.
To explain the differences as relevant to your posted example:
a. When you use RegisterStartupScript
, it will render your script after all the elements in the page (right before the form's end tag). This enables the script to call or reference page elements without the possibility of it not finding them in the Page's DOM.
Here is the rendered source of the page when you invoke the RegisterStartupScript
method:
<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1"><title></title></head>
<body>
<form name="form1" method="post" action="StartupScript.aspx" id="form1">
<div>
<input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="someViewstategibberish" />
</div>
<div> <span id="lblDisplayDate">Label</span>
<br />
<input type="submit" name="btnPostback" value="Register Startup Script" id="btnPostback" />
<br />
<input type="submit" name="btnPostBack2" value="Register" id="btnPostBack2" />
</div>
<div>
<input type="hidden" name="__EVENTVALIDATION" id="__EVENTVALIDATION" value="someViewstategibberish" />
</div>
<!-- Note this part -->
<script language='javascript'>
var lbl = document.getElementById('lblDisplayDate');
lbl.style.color = 'red';
</script>
</form>
<!-- Note this part -->
</body>
</html>
b. When you use RegisterClientScriptBlock
, the script is rendered right after the Viewstate tag, but before any of the page elements. Since this is a direct script (not a function that can be called, it will immediately be executed by the browser. But the browser does not find the label in the Page's DOM at this stage and hence you should receive an "Object not found" error.
Here is the rendered source of the page when you invoke the RegisterClientScriptBlock
method:
<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1"><title></title></head>
<body>
<form name="form1" method="post" action="StartupScript.aspx" id="form1">
<div>
<input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="someViewstategibberish" />
</div>
<script language='javascript'>
var lbl = document.getElementById('lblDisplayDate');
// Error is thrown in the next line because lbl is null.
lbl.style.color = 'green';
Therefore, to summarize, you should call the latter method if you intend to render a function definition. You can then render the call to that function using the former method (or add a client side attribute).
Edit after comments:
For instance, the following function would work:
protected void btnPostBack2_Click(object sender, EventArgs e)
{
System.Text.StringBuilder sb = new System.Text.StringBuilder();
sb.Append("<script language='javascript'>function ChangeColor() {");
sb.Append("var lbl = document.getElementById('lblDisplayDate');");
sb.Append("lbl.style.color='green';");
sb.Append("}</script>");
//Render the function definition.
if (!ClientScript.IsClientScriptBlockRegistered("JSScriptBlock"))
{
ClientScript.RegisterClientScriptBlock(this.GetType(), "JSScriptBlock", sb.ToString());
}
//Render the function invocation.
string funcCall = "<script language='javascript'>ChangeColor();</script>";
if (!ClientScript.IsStartupScriptRegistered("JSScript"))
{
ClientScript.RegisterStartupScript(this.GetType(), "JSScript", funcCall);
}
}
This was the reason why I was getting it:
I had an ASP:ListBox. Initially it was hidden. At client side I would populate it via AJAX with options. The user chose one option. Then when clicking the Submit button, the Server would get all funny about the ListBox, since it did not remember it having any options.
So what I did is to make sure I clear all the list options before submitting the form back to the server. That way the server did not complain since the list went to the client empty and it came back empty.
Sorted!!!
Do something like this:
if($request->hasFile('video')){
$video=$request->file('video');
$filename=str_random(20).".".$video->extension();
$path = Storage::putFileAs(
'/', $video, $filename
);
$data['video']=$filename;
}
Use a subquery in the where clause. For a delete query requirig a join, this example will delete rows that are unmatched in the joined table "docx_document" and that have a create date > 120 days in the "docs_documents" table.
delete from docs_documents d
where d.id in (
select a.id from docs_documents a
left join docx_document b on b.id = a.document_id
where b.id is null
and floor(sysdate - a.create_date) > 120
);
echo "message" | git commit-tree HEAD^{tree}
This will create an orphaned commit with the tree of HEAD, and output its name (SHA-1) on stdout. Then just reset your branch there.
git reset SHA-1
To do the above in a single step:
git reset $(git commit-tree HEAD^{tree} -m "commit message")
I'm not sure I understand your question. But there are two approaches to making the image invisible...
Pure HTML
<img src="a.gif" style="display: none;" />
Or...
HTML + Javascript
<script type="text/javascript">
document.getElementById("myImage").style.display = "none";
</script>
<img id="myImage" src="a.gif" />
In a KeyPress event, if the user pressed Enter, call
SendKeys.Send("{TAB}")
Nicest way to implement automatically selecting the text on receiving focus is to create a subclass of TextBox in your project with the following override:
Protected Overrides Sub OnGotFocus(ByVal e As System.EventArgs)
SelectionStart = 0
SelectionLength = Text.Length
MyBase.OnGotFocus(e)
End Sub
Then use this custom TextBox in place of the WinForms standard TextBox on all your Forms.
The following code describes a simple example using POST
method.(How one can pass data by POST
method)
Here, I describe how one can use of POST method.
1. Set post string with actual username and password.
NSString *post = [NSString stringWithFormat:@"Username=%@&Password=%@",@"username",@"password"];
2. Encode the post string using NSASCIIStringEncoding
and also the post string you need to send in NSData format.
NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
You need to send the actual length of your data. Calculate the length of the post string.
NSString *postLength = [NSString stringWithFormat:@"%d",[postData length]];
3. Create a Urlrequest with all the properties like HTTP
method, http header field with length of the post string. Create URLRequest
object and initialize it.
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
Set the Url for which your going to send the data to that request.
[request setURL:[NSURL URLWithString:@"http://www.abcde.com/xyz/login.aspx"]];
Now, set HTTP method (POST or GET). Write this lines as it is in your code.
[request setHTTPMethod:@"POST"];
Set HTTP
header field with length of the post data.
[request setValue:postLength forHTTPHeaderField:@"Content-Length"];
Also set the Encoded value for HTTP header Field.
[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
Set the HTTPBody
of the urlrequest with postData.
[request setHTTPBody:postData];
4. Now, create URLConnection object. Initialize it with the URLRequest.
NSURLConnection *conn = [[NSURLConnection alloc] initWithRequest:request delegate:self];
It returns the initialized url connection and begins to load the data for the url request. You can check that whether you URL
connection is done properly or not using just if/else statement as below.
if(conn) {
NSLog(@"Connection Successful");
} else {
NSLog(@"Connection could not be made");
}
5. To receive the data from the HTTP request , you can use the delegate methods provided by the URLConnection Class Reference. Delegate methods are as below.
// This method is used to receive the data which we get using post method.
- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData*)data
// This method receives the error report in case of connection is not made to server.
- (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error
// This method is used to process the data after connection has made successfully.
- (void)connectionDidFinishLoading:(NSURLConnection *)connection
Also Refer This and This documentation for POST
method.
And here is best example with source code of HTTPPost Method.
For finding objects which are meaningfully equal, you need to override equals
and hashcode
methods for the class. You can find a good tutorial here.

When it comes to inserting a picture, r2evans's suggestion of ![Caption for the picture.](/path/to/image.png)
can be problematic if PDF output is required.
The knitr function include_graphics
knitr::include_graphics('/path/to/image.png')
is a more portable alternative
that will generate, on your behalf, the markdown that is most appropriate to the output format that you are generating.
I can't believe I haven't found this simple solution anywhere on stack overflow yet, it is by far the most useful. Changing the Document or DocumentFilter does not work for JFormattedTextField. Peter Tseng's answer comes very close.
NumberFormat longFormat = NumberFormat.getIntegerInstance();
NumberFormatter numberFormatter = new NumberFormatter(longFormat);
numberFormatter.setValueClass(Long.class); //optional, ensures you will always get a long value
numberFormatter.setAllowsInvalid(false); //this is the key!!
numberFormatter.setMinimum(0l); //Optional
JFormattedTextField field = new JFormattedTextField(numberFormatter);
To see all the installed packages locally or globally, use these commands:
npm list
for local packages or npm list -g
for globally installed packages.npm list --depth=0
npm list | sls <package name>
node -v
Dim a As Range, b As Range
Set a = Selection
For Each b In a.Rows
MsgBox b.Address
Next
You can wrap your query in another SELECT
:
select count(*)
from
(
select count(SID) tot -- add alias
from Test
where Date = '2012-12-10'
group by SID
) src; -- add alias
In order for it to work, the count(SID)
need a column alias and you have to provide an alias to the subquery itself.
Your chunk size could be too large, have you tried dropping that - maybe 1024 bytes at a time? (also, you could use with
to tidy up the syntax)
def DownloadFile(url):
local_filename = url.split('/')[-1]
r = requests.get(url)
with open(local_filename, 'wb') as f:
for chunk in r.iter_content(chunk_size=1024):
if chunk: # filter out keep-alive new chunks
f.write(chunk)
return
Incidentally, how are you deducing that the response has been loaded into memory?
It sounds as if python isn't flushing the data to file, from other SO questions you could try f.flush()
and os.fsync()
to force the file write and free memory;
with open(local_filename, 'wb') as f:
for chunk in r.iter_content(chunk_size=1024):
if chunk: # filter out keep-alive new chunks
f.write(chunk)
f.flush()
os.fsync(f.fileno())
try this. m = row, n = col
vector<vector<int>> matrix(m, vector<int>(n));
for(i = 0;i < m; i++)
{
for(j = 0; j < n; j++)
{
cin >> matrix[i][j];
}
cout << endl;
}
cout << "::matrix::" << endl;
for(i = 0; i < m; i++)
{
for(j = 0; j < n; j++)
{
cout << matrix[i][j] << " ";
}
cout << endl;
}
If you use CURLOPT_COOKIE_FILE and CURLOPT_COOKIE_JAR curl will read/write the cookies from/to a file. You can, after curl is done with it, read and/or modify it however you want.
First you should drop the problematic DEFAULT constraint
, after that you can drop the column
alter table tbloffers drop constraint [ConstraintName]
go
alter table tbloffers drop column checkin
But the error may appear from other reasons - for example the user defined function or view with SCHEMABINDING
option set for them.
UPD: Completely automated dropping of constraints script:
DECLARE @sql NVARCHAR(MAX)
WHILE 1=1
BEGIN
SELECT TOP 1 @sql = N'alter table tbloffers drop constraint ['+dc.NAME+N']'
from sys.default_constraints dc
JOIN sys.columns c
ON c.default_object_id = dc.object_id
WHERE
dc.parent_object_id = OBJECT_ID('tbloffers')
AND c.name = N'checkin'
IF @@ROWCOUNT = 0 BREAK
EXEC (@sql)
END
For anyone who, like me, reads this because they need to update a giant legacy project to 5.6: as the answers here point out, there is no quick fix: you really do need to find each occurrence of the problem manually, and fix it.
The most convenient way I found to find all problematic lines in a project (short of using a full-blown static code analyzer, which is very accurate but I don't know any that take you to the correct position in the editor right away) was using Visual Studio Code, which has a nice PHP linter built in, and its search feature which allows searching by Regex. (Of course, you can use any IDE/Code editor for this that does PHP linting and Regex searches.)
Using this regex:
^(?!.*function).*(\&\$)
it is possible to search project-wide for the occurrence of &$
only in lines that are not a function definition.
This still turns up a lot of false positives, but it does make the job easier.
VSCode's search results browser makes walking through and finding the offending lines super easy: you just click through each result, and look out for those that the linter underlines red. Those you need to fix.
Just some additions to previous answers. There are aliases defined for Get-Content, for example if you are used to UNIX you might like cat
, and there are also type
and gc
. So instead of
Get-Content -Path <Path> -Wait -Tail 10
you can write
# Print whole file and wait for appended lines and print them
cat <Path> -Wait
# Print last 10 lines and wait for appended lines and print them
cat <Path> -Tail 10 -Wait
Create images
folder in root level of your project.
Drop your image in this folder, it should look like
Go to your pubspec.yaml
file, add assets
header and pay close attention to all the spaces.
flutter:
uses-material-design: true
# add this
assets:
- images/profile.jpg
Tap on Packages get
at the top right corner of the IDE.
Now you can use your image anywhere using
Image.asset("images/profile.jpg")
You need to use a graphics library. Put this in your preamble:
\usepackage{graphicx}
You can then add images like this:
\begin{figure}[ht!]
\centering
\includegraphics[width=90mm]{fixed_dome1.jpg}
\caption{A simple caption \label{overflow}}
\end{figure}
This is the basic template I use in my documents. The position and size should be tweaked for your needs. Refer to the guide below for more information on what parameters to use in \figure
and \includegraphics
. You can then refer to the image in your text using the label you gave in the figure:
And here we see figure \ref{overflow}.
Read this guide here for a more detailed instruction: http://en.wikibooks.org/wiki/LaTeX/Floats,_Figures_and_Captions
You can use the ljust
method on strings.
>>> name = 'John'
>>> name.ljust(15)
'John '
Note that if the name is longer than 15 characters, ljust
won't truncate it. If you want to end up with exactly 15 characters, you can slice the resulting string:
>>> name.ljust(15)[:15]
There is not much I can add to the what and why of the P=?NP part of the question, but in regards to the proof. Not only would a proof be worth some extra credit, but it would solve one of the Millennium Problems. An interesting poll was recently conducted and the published results (PDF) are definitely worth reading in regards to the subject of a proof.
net use "m:\Server01\my folder" /USER:mynetwork\Administrator "Mypassword" /persistent:yes
does not work?
def func(*args):
pass
When you define a function this way, *args
will be array of arguments passed to the function. This allows your function to work without knowing ahead of time how many arguments are going to be passed to it.
You do this with keyword arguments too, using **kwargs
:
def func2(**kwargs):
pass
In your case, you've defined a class which is acting like a dictionary. The dict.pop
method is defined as pop(key[, default])
.
Your method doesn't use the default
parameter. But, by defining your method with *args
and passing *args
to dict.pop()
, you are allowing the caller to use the default
parameter.
In other words, you should be able to use your class's pop
method like dict.pop
:
my_a = a()
value1 = my_a.pop('key1') # throw an exception if key1 isn't in the dict
value2 = my_a.pop('key2', None) # return None if key2 isn't in the dict
No, there is not really any other way : if you have many locations and want to display them on a map, the best solution is to :
This is, of course, considering that you have a lot less creation/modification of locations than you have consultations of locations.
Yes, it means you'll have to do a bit more work when saving the locations -- but it also means :
You want DateTime.DaysInMonth
:
int days = DateTime.DaysInMonth(year, month);
Obviously it varies by year, as sometimes February has 28 days and sometimes 29. You could always pick a particular year (leap or not) if you want to "fix" it to one value or other.

I did this with Android Studio 3.1.4 and it allowed me to create a release apk after following all the steps above of creating the release apk and release key and adding the info to the app gradle. Cheers!
It is another type of layer, so you should add it as a layer in an appropriate place of your model
model.add(keras.layers.normalization.BatchNormalization())
See an example here: https://github.com/fchollet/keras/blob/master/examples/kaggle_otto_nn.py
If you don't mind the dictionary values being tuples, you can use itertuples:
>>> {x[0]: x[1:] for x in df.itertuples(index=False)}
{'p': (1, 3, 2), 'q': (4, 3, 2), 'r': (4, 0, 9)}
As per matplotlib's suggestion for image grids:
import matplotlib.pyplot as plt
from mpl_toolkits.axes_grid1 import ImageGrid
fig = plt.figure(figsize=(4., 4.))
grid = ImageGrid(fig, 111, # similar to subplot(111)
nrows_ncols=(2, 2), # creates 2x2 grid of axes
axes_pad=0.1, # pad between axes in inch.
)
for ax, im in zip(grid, image_data):
# Iterating over the grid returns the Axes.
ax.imshow(im)
plt.show()
TO ADDRESS THE FINAL CLASS PROBLEM:
There are two ways to make a class final. The first is to use the keyword final in the class declaration:
public final class SomeClass {
// . . . Class contents
}
The second way to make a class final is to declare all of its constructors as private:
public class SomeClass {
public final static SOME_INSTANCE = new SomeClass(5);
private SomeClass(final int value) {
}
Marking it final saves you the trouble if finding out that it is actual a final, to demonstrate look at this Test class. looks public at first glance.
public class Test{
private Test(Class beanClass, Class stopClass, int flags)
throws Exception{
// . . . snip . . .
}
}
Unfortunately, since the only constructor of the class is private, it is impossible to extend this class. In the case of the Test class, there is no reason that the class should be final. The Test class is a good example of how implicit final classes can cause problems.
So you should mark it final when you implicitly make a class final by making it's constructor private.
Yes, it works. Check the below example. Assuming @value is not int
WITH CTE
AS
(
SELECT NULL AS test
UNION
SELECT '' AS test
UNION
SELECT '123' AS test
)
SELECT
CASE WHEN isnull(test,'')='' THEN 'empty' ELSE test END AS IS_EMPTY

None of these solutions quite worked for me. My original audio was being overwritten, or I was getting an error like "failed to map memory" with the more complex 'amerge' example. It seems I needed -filter_complex amix.

I have tried to solve this question for years now, I thought I found a shorter solution but had to come back again to the long story. This function gives back the right ISO week notation:

I found out that my short solution missed the 2018-12-31 as it gave back 1801 instead of 1901. So I had to put in this long version which is correct.
There are specific suffixes for long
(e.g. 39832L
), float
(e.g. 2.4f
) and double
(e.g. -7.832d
).
If there is no suffix, and it is an integral type (e.g. 5623
), it is assumed to be an int
. If it is not an integral type (e.g. 3.14159
), it is assumed to be a double
.
In all other cases (byte
, short
, char
), you need the cast as there is no specific suffix.
The Java spec allows both upper and lower case suffixes, but the upper case version for long
s is preferred, as the upper case L
is less easy to confuse with a numeral 1
than the lower case l
.
See the JLS section 3.10 for the gory details (see the definition of IntegerTypeSuffix
).
Although MSDN says that "s" and "o" formats reflect the standard, they seem to be able to parse only a limited subset of it. Especially it is a problem if the string contains time zone specification. (Neither it does for basic ISO8601 formats, or reduced precision formats - however this is not exactly your case.) That is why I make use of custom format strings when it comes to parsing ISO8601. Currently my preferred snippet is:
static readonly string[] formats = {
// Basic formats
"yyyyMMddTHHmmsszzz",
"yyyyMMddTHHmmsszz",
"yyyyMMddTHHmmssZ",
// Extended formats
"yyyy-MM-ddTHH:mm:sszzz",
"yyyy-MM-ddTHH:mm:sszz",
"yyyy-MM-ddTHH:mm:ssZ",
// All of the above with reduced accuracy
"yyyyMMddTHHmmzzz",
"yyyyMMddTHHmmzz",
"yyyyMMddTHHmmZ",
"yyyy-MM-ddTHH:mmzzz",
"yyyy-MM-ddTHH:mmzz",
"yyyy-MM-ddTHH:mmZ",
// Accuracy reduced to hours
"yyyyMMddTHHzzz",
"yyyyMMddTHHzz",
"yyyyMMddTHHZ",
"yyyy-MM-ddTHHzzz",
"yyyy-MM-ddTHHzz",
"yyyy-MM-ddTHHZ"
};
public static DateTime ParseISO8601String ( string str )
{
return DateTime.ParseExact ( str, formats,
CultureInfo.InvariantCulture, DateTimeStyles.None );
}
If you don't mind parsing TZ-less strings (I do), you can add an "s" line to greatly extend the number of covered format alterations.
Use lang attribut on the input. Locale on my web app fr_FR, lang="en_EN" on the input number and i can use indifferently a comma or a dot. Firefox always display a dot, Chrome display a comma. But both separtor are valid.
The standard solution didn't work for me, when changing the type from TEXT to LONGTEXT.
I had to it like this:
public function up()
{
DB::statement('ALTER TABLE mytable MODIFY mycolumn LONGTEXT;');
}
public function down()
{
DB::statement('ALTER TABLE mytable MODIFY mycolumn TEXT;');
}
This could be a Doctrine issue. More information here.
Another way to do it is to use the string() method, and set the value to the text type max length:
Schema::table('mytable', function ($table) {
// Will set the type to LONGTEXT.
$table->string('mycolumn', 4294967295)->change();
});
I faced the same problem with JBoss 4.2.3 GA when deploying my web application. I solved the issue by copying my commons-codec 1.6 jar into C:\jboss-4.2.3.GA\server\default\lib
You can use T-SQL to convert the date before it gets to your .NET program. This often is simpler if you don't need to do additional date conversion in your .NET program.
DECLARE @Date DATETIME = Getdate()
DECLARE @DateInt INT = CONVERT(VARCHAR(30), @Date, 112)
DECLARE @TimeInt INT = REPLACE(CONVERT(VARCHAR(30), @Date, 108), ':', '')
DECLARE @DateTimeInt BIGINT = CONVERT(VARCHAR(30), @Date, 112) + REPLACE(CONVERT(VARCHAR(30), @Date, 108), ':', '')
SELECT @Date as Date, @DateInt DateInt, @TimeInt TimeInt, @DateTimeInt DateTimeInt
Date DateInt TimeInt DateTimeInt

Let's discuss why an "object not found" error can be thrown in R in addition to explaining what it means. What it means (to many) is obvious: the variable in question, at least according to the R interpreter, has not yet been defined, but if you see your object in your code there can be multiple reasons for why this is happening:
check syntax of your declarations. If you mis-typed even one letter or used upper case instead of lower case in a later calling statement, then it won't match your original declaration and this error will occur.
Are you getting this error in a notebook or markdown document? You may simply need to re-run an earlier cell that has your declarations before running the current cell where you are calling the variable.
Are you trying to knit your R document and the variable works find when you run the cells but not when you knit the cells? If so - then you want to examine the snippet I am providing below for a possible side effect that triggers this error:
{r sourceDataProb1, echo=F, eval=F}
# some code here
The above snippet is from the beginning of an R markdown cell. If eval and echo are both set to False this can trigger an error when you try to knit the document. To clarify. I had a use case where I had left these flags as False because I thought i did not want my code echoed or its results to show in the markdown HTML I was generating. But since the variable was then used in later cells, this caused an error during knitting. Simple trial and error with T/F TRUE/FALSE flags can establish if this is the source of your error when it occurs in knitting an R markdown document from RStudio.
Lastly: did you remove the variable or clear it from memory after declaring it?
Just list an alternaitve solution here, the Advertising ID:

The advertising ID is a unique, user-resettable ID for advertising, provided by Google Play services. It gives users better controls and provides developers with a simple, standard system to continue to monetize their apps. It enables users to reset their identifier or opt out of personalized ads (formerly known as interest-based ads) within Google Play apps.

java.lang.NoSuchMethodError: javax.servlet.ServletContext.getContextPath()Ljava/lang/String;
That method was added in Servlet 2.5.
So this problem can have at least 3 causes:
web.xml
is not declared conform Servlet 2.5 or newer.To solve it,
web.xml
complies Servlet 2.5 (or newer, at least the highest whatever your target runtime supports). For an example, see also somewhere halfway our servlets wiki page.servlet-api.jar
or j2ee.jar
in /WEB-INF/lib
or even worse, the JRE/lib
or JRE/lib/ext
. They do not belong there. This is a pretty common beginner's mistake in an attempt to circumvent compilation errors in an IDE, see also How do I import the javax.servlet API in my Eclipse project?.There are many ways to achieve this, like flatten-and-filter or simply enumerate, but I think using Boolean/mask array is the easiest one (and iirc a much faster one):
>>> y = np.array([[123,24123,32432], [234,24,23]])
array([[ 123, 24123, 32432],
[ 234, 24, 23]])
>>> b = y > 200
>>> b
array([[False, True, True],
[ True, False, False]], dtype=bool)
>>> y[b]
array([24123, 32432, 234])
>>> len(y[b])
3
>>>> y[b].sum()
56789
Update:
As nneonneo has answered, if all you want is the number of elements that passes threshold, you can simply do:
>>>> (y>200).sum()
3
which is a simpler solution.

I got the solution for the Android Studio installation after trying everything that I could find on the Internet. If you're using Android Studio and getting this error:
Find [Path_to_Android_SDK]\sdk\tools\android.bat
.
In my case, it was in C:\Users\Nathan\AppData\Local\Android\android-studio\sdk\tools\android.bat
.
Right-click it, hit Edit
, and scroll all the way down to the bottom.
Find where it says: call %java_exe% %REMOTE_DEBUG% ...
Replace that with call %java_exe% -Djava.net.preferIPv4Stack=true %REMOTE_DEBUG% ...
Restart Android Studio/SDK and everything works. This fixed many issues for me, including being unable to fetch XML files or create new projects.
Any other solution/library is in the end going to use reflection to introspect the type...

slice()
works like substring()
with a few different behaviors.
Syntax: string.slice(start, stop);
Syntax: string.substring(start, stop);
What they have in common:
start
equals stop
: returns an empty stringstop
is omitted: extracts characters to the end of the stringDistinctions of substring()
:
start > stop
, then substring
will swap those 2 arguments.NaN
, it is treated as if it were 0
.Distinctions of slice()
:
start > stop
, slice()
will return the empty string. (""
)start
is negative: sets char from the end of string, exactly like substr()
in Firefox. This behavior is observed in both Firefox and IE.stop
is negative: sets stop to: string.length – Math.abs(stop)
(original value), except bounded at 0 (thus, Math.max(0, string.length + stop)
) as covered in the ECMA specification.Source: Rudimentary Art of Programming & Development: Javascript: substr() v.s. substring()

To add to the other answers, by implementating java.io.Serializable
, you get "automatic" serialization capability for objects of your class. No need to implement any other logic, it'll just work. The Java runtime will use reflection to figure out how to marshal and unmarshal your objects.
In earlier version of Java, reflection was very slow, and so serializaing large object graphs (e.g. in client-server RMI applications) was a bit of a performance problem. To handle this situation, the java.io.Externalizable
interface was provided, which is like java.io.Serializable
but with custom-written mechanisms to perform the marshalling and unmarshalling functions (you need to implement readExternal
and writeExternal
methods on your class). This gives you the means to get around the reflection performance bottleneck.
In recent versions of Java (1.3 onwards, certainly) the performance of reflection is vastly better than it used to be, and so this is much less of a problem. I suspect you'd be hard-pressed to get a meaningful benefit from Externalizable
with a modern JVM.
Also, the built-in Java serialization mechanism isn't the only one, you can get third-party replacements, such as JBoss Serialization, which is considerably quicker, and is a drop-in replacement for the default.
A big downside of Externalizable
is that you have to maintain this logic yourself - if you add, remove or change a field in your class, you have to change your writeExternal
/readExternal
methods to account for it.
In summary, Externalizable
is a relic of the Java 1.1 days. There's really no need for it any more.
While some of the answers were very useful and informative, I thought I would write down the answer I came up with. The answer from Alex was very good, it is however limited in the sense that the height of the div needs to be hard coded in the CSS.
So the solution I came up with uses JS (no jQuery) and is actually a stripped down version (almost to the minimum) of over solutions to solve similar problems I found on Statckoverflow:
HTML
<div class="header">
<p class="menu"><a href="#S1" onclick="test('S1'); return false;">S1</a></p>
<p class="menu"><a href="#S2" onclick="test('S2'); return false;">S2</a></p>
<p class="menu"><a href="#S3" onclick="test('S3'); return false;">S3</a></p>
<p class="menu"><a href="#S4" onclick="test('S4'); return false;">S3</a></p>
</div>
<div style="width: 100%;">
<div id="S1" class="curtain">
blabla
</div>
<div id="S2" class="curtain">
blabla
</div>
<div id="S3" class="curtain">
blabla
</div>
<div id="S4" class="curtain">
blabla
</div>
</div>
NOTE THE "RETURN FALSE;" in the on click call. This is important if you want to avoid having your browser jumping to the link itself (and let the effect being managed by your JS).
JS code:
<script>
function scrollTo(to, duration) {
if (document.body.scrollTop == to) return;
var diff = to - document.body.scrollTop;
var scrollStep = Math.PI / (duration / 10);
var count = 0, currPos;
start = element.scrollTop;
scrollInterval = setInterval(function(){
if (document.body.scrollTop != to) {
count = count + 1;
currPos = start + diff * (0.5 - 0.5 * Math.cos(count * scrollStep));
document.body.scrollTop = currPos;
}
else { clearInterval(scrollInterval); }
},10);
}
function test(elID)
{
var dest = document.getElementById(elID);
scrollTo(dest.offsetTop, 500);
}
</script>
It's incredibly simple. It finds the vertical position of the div in the document using its unique ID (in the function test). Then it calls the scrollTo function passing the starting position (document.body.scrollTop) and the destination position (dest.offsetTop). It performs the transition using some sort of ease-inout curve.
Thanks everyone for your help.
Knowing a bit of coding can help you avoiding (sometimes heavy) libraries, and giving you (the programmer) more control.

For those who still have this problem, and none of the above solutions worked for you:
Update your versions of java and Eclipse.
In my case, I updated from java 7 to java 9, and Eclipse Mars to Eclipse Oxygen, and this problem was solved !!!
I would go with Option 3 but multiple NON NULLABLE bit columns instead of one. IsMale (1=Yes / 0=No) IsFemale (1=Yes / 0=No)
if requried: IsUnknownGender (1=Yes / 0=No) and so on...
This makes for easy reading of the definitions, easy extensibility, easy programmability, no possibility of using values outside the domain and no requirement of a second lookup table+FK or CHECK constraints to lock down the values.
EDIT: Correction, you do need at least one constraint to ensure the set flags are valid.

I haven't tried it, but iOS WebKit debug proxy (ios_webkit_debug_proxy / iwdp) supposedly lets you remotely debug UIWebView. From the README.md
The ios_webkit_debug_proxy (aka iwdp) allows developers to inspect MobileSafari and UIWebViews on real and simulated iOS devices via the Chrome DevTools UI and Chrome Remote Debugging Protocol. DevTools requests are translated into Apple's Remote Web Inspector service calls.
The above answers did not work for me. The below does:
document.getElementById("input_field_id").setAttribute("readonly", true);
And to remove the readonly attribute:
document.getElementById("input_field_id").removeAttribute("readonly");
And for running when the page is loaded, it is worth referring to here.
Java 1.7 makes our lives much easier thanks to the try-with-resources statement.
try (Connection connection = dataSource.getConnection();
Statement statement = connection.createStatement()) {
try (ResultSet resultSet = statement.executeQuery("some query")) {
// Do stuff with the result set.
}
try (ResultSet resultSet = statement.executeQuery("some query")) {
// Do more stuff with the second result set.
}
}
This syntax is quite brief and elegant. And connection
will indeed be closed even when the statement
couldn't be created.
This should work.
SELECT a.[CUSTOMER ID], a.[NAME], SUM(b.[AMOUNT]) AS [TOTAL AMOUNT]
FROM RES_DATA a INNER JOIN INV_DATA b
ON a.[CUSTOMER ID]=b.[CUSTOMER ID]
GROUP BY a.[CUSTOMER ID], a.[NAME]
I tested it with SQL Fiddle against SQL Server 2008: http://sqlfiddle.com/#!3/1cad5/1
Basically what's happening here is that, because of the join, you are getting the same row on the "left" (i.e. from the RES_DATA
table) for every row on the "right" (i.e. the INV_DATA
table) that has the same [CUSTOMER ID]
value. When you group by just the columns on the left side, and then do a sum of just the [AMOUNT]
column from the right side, it keeps the one row intact from the left side, and sums up the matching values from the right side.
Pipe to gawk:
cat files.txt | xargs ls -l | cut -c 23-30 | gawk 'BEGIN { sum = 0 } // { sum = sum + $0 } END { print sum }'
Something like this may work for you... It will probably require you to have set column widths for your header row.

My use case is similar, except that I want a log cleanup event to run at 2am every night. As I said in the comment above, the DAY_HOUR doesn't work for me. In my case I don't really mind potentially missing the first day (and, given it is to run at 2am then 2am tomorrow is almost always the next 2am) so I use:
CREATE EVENT applog_clean_event
ON SCHEDULE
EVERY 1 DAY
STARTS str_to_date( date_format(now(), '%Y%m%d 0200'), '%Y%m%d %H%i' ) + INTERVAL 1 DAY

Here is my take on a non recursive version
My 242-line .vimrc
is not that interesting, but since nobody mentioned it, I felt like I must share the two most important mappings that have enhanced my workflow besides the default mappings:
map <C-j> :bprev<CR>
map <C-k> :bnext<CR>
set hidden " this will go along
Seriously, switching buffers is the thing to do very often. Windows, sure, but everything doesn't fit the screen so nicely.
Similar set of maps for quick browsing of errors (see quickfix) and grep results:
map <C-n> :cn<CR>
map <C-m> :cp<CR>
Simple, effortless and efficient.
This answer is for anyone encountering pdfs with images and needing to use OCR. I could not find a workable off-the-shelf solution; nothing that gave me the accuracy I needed.
Here are the steps I found to work.
Use pdfimages
from https://poppler.freedesktop.org/ to turn the pages of the pdf into images.
Use Tesseract to detect rotation and ImageMagick mogrify
to fix it.
Use OpenCV to find and extract tables.
Use OpenCV to find and extract each cell from the table.
Use OpenCV to crop and clean up each cell so that there is no noise that will confuse OCR software.
Use Tesseract to OCR each cell.
Combine the extracted text of each cell into the format you need.
I wrote a python package with modules that can help with those steps.
Repo: https://github.com/eihli/image-table-ocr
Docs & Source: https://eihli.github.io/image-table-ocr/pdf_table_extraction_and_ocr.html
Some of the steps don't require code, they take advantage of external tools like pdfimages
and tesseract
. I'll provide some brief examples for a couple of the steps that do require code.
This link was a good reference while figuring out how to find tables. https://answers.opencv.org/question/63847/how-to-extract-tables-from-an-image/

image_width, image_height = horizontal.shape
horizontal_kernel = cv2.getStructuringElement(cv2.MORPH_RECT, (int(image_width / SCALE), 1))

This is very similar to 2, so I won't include all the code. The part I will reference will be in sorting the cells.
We want to identify the cells from left-to-right, top-to-bottom.
We’ll find the rectangle with the most top-left corner. Then we’ll find all of the rectangles that have a center that is within the top-y and bottom-y values of that top-left rectangle. Then we’ll sort those rectangles by the x value of their center. We’ll remove those rectangles from the list and repeat.
def cell_in_same_row(c1, c2):
c1_center = c1[1] + c1[3] - c1[3] / 2
c2_bottom = c2[1] + c2[3]
c2_top = c2[1]
return c2_top < c1_center < c2_bottom
orig_cells = [c for c in cells]
rows = []
while cells:
first = cells[0]
rest = cells[1:]
cells_in_same_row = sorted(
[
c for c in rest
if cell_in_same_row(c, first)
],
key=lambda c: c[0]
)
row_cells = sorted([first] + cells_in_same_row, key=lambda c: c[0])
rows.append(row_cells)
cells = [
c for c in rest
if not cell_in_same_row(c, first)
]
# Sort rows by average height of their center.
def avg_height_of_center(row):
centers = [y + h - h / 2 for x, y, w, h in row]
return sum(centers) / len(centers)
rows.sort(key=avg_height_of_center)
You're missing *
s in the last two terms of your expression, so R is interpreting (e.g.) 0.207 (log(DIAM93))^2
as an attempt to call a function named 0.207
...
For example:
> 1 + 2*(3)
[1] 7
> 1 + 2 (3)
Error: attempt to apply non-function
Your (unreproducible) expression should read:
censusdata_20$AGB93 = WD * exp(-1.239 + 1.980 * log (DIAM93) +
0.207* (log(DIAM93))^2 -
0.0281*(log(DIAM93))^3)
Mathematica is the only computer system I know of that allows juxtaposition to be used for multiplication ...
I used:
Get-Content c:\FileToAppend_*.log | Out-File -FilePath C:\DestinationFile.log
-Encoding ASCII -Append
This appended fine. I added the ASCII encoding to remove the nul characters Notepad++ was showing without the explicit encoding.
As Tuomas said, your header should be minimal. To be complete I will expand a bit.
I personally use 4 types of files in my C++
projects:
Furthermore, I couple this with another rule: Do not define what you can forward declare. Though of course I am reasonable there (using Pimpl everywhere is quite a hassle).
It means that I prefer a forward declaration over an #include
directive in my headers whenever I can get away with them.
Finally, I also use a visibility rule: I limit the scopes of my symbols as much as possible so that they do not pollute the outer scopes.
Putting it altogether:
// example_fwd.hpp
// Here necessary to forward declare the template class,
// you don't want people to declare them in case you wish to add
// another template symbol (with a default) later on
class MyClass;
template <class T> class MyClassT;
// example.hpp
#include "project/example_fwd.hpp"
// Those can't really be skipped
#include <string>
#include <vector>
#include "project/pimpl.hpp"
// Those can be forward declared easily
#include "project/foo_fwd.hpp"
namespace project { class Bar; }
namespace project
{
class MyClass
{
public:
struct Color // Limiting scope of enum
{
enum type { Red, Orange, Green };
};
typedef Color::type Color_t;
public:
MyClass(); // because of pimpl, I need to define the constructor
private:
struct Impl;
pimpl<Impl> mImpl; // I won't describe pimpl here :p
};
template <class T> class MyClassT: public MyClass {};
} // namespace project
// example_impl.hpp (not visible to clients)
#include "project/example.hpp"
#include "project/bar.hpp"
template <class T> void check(MyClass<T> const& c) { }
// example.cpp
#include "example_impl.hpp"
// MyClass definition
The lifesaver here is that most of the times the forward header is useless: only necessary in case of typedef
or template
and so is the implementation header ;)
Do not forget to exclude carriage returns from your data !!!
as in:
SELECT
Myotherval
, CASE WHEN TRIM(REPLACE([MyVal], char(13) + char(10), '')) not like '%[^0-9]%' and RTRIM(REPLACE([MyVal], char(13) + char(10), '')) not like '.' and isnumeric(REPLACE([MyVal], char(13) + char(10), '')) = 1 THEN 'my number: ' + [MyVal]
ELSE ISNULL(Cast([MyVal] AS VARCHAR(8000)), '')
END AS 'MyVal'

Same idea as Yuushi in using regular expressions, but this uses the findall method within the re library instead of a list comprehension:
import re
regex = re.compile('th.s')
l = ['this', 'is', 'just', 'a', 'test']
matches = re.findall(regex, string)
This question is over 5 years old but every answer has some problems.
Scroll down for examples to serve an image with:
express.static
express
connect
http
net
All of the examples are also on GitHub: https://github.com/rsp/node-static-http-servers
Test results are available on Travis: https://travis-ci.org/rsp/node-static-http-servers
After over 5 years since this question was asked there is only one correct answer by generalhenry but even though that answer has no problems with the code, it seems to have some problems with reception. It was commented that it "doesn't explain much other than how to rely on someone else to get the job done" and the fact how many people have voted this comment up clearly shows that a lot of things need clarification.
First of all, a good answer to "How to serve images using Node.js" is not implementing a static file server from scratch and doing it badly. A good answer is using a module like Express that does the job correctly.
Answering comments that say that using Express "doesn't explain much other than how to rely on someone else to get the job done" it should be noted, that using the http
module already relies on someone else to get the job done. If someone doesn't want to rely on anyone to get the job done then at least raw TCP sockets should be used instead - which I do in one of my examples below.
A more serious problem is that all of the answers here that use the http
module are broken. They introduce race conditions, insecure path resolution that will lead to path traversal vulnerability, blocking I/O that will completely fail to serve any concurrent requests at all and other subtle problems - they are completely broken as examples of what the question asks about, and yet they already use the abstraction that is provided by the http
module instead of using TCP sockets so they don't even do everything from scratch as they claim.
If the question was "How to implement static file server from scratch, as a learning exercise" then by all means answers how to do that should be posted - but even then we should expect them to at least be correct. Also, it is not unreasonable to assume that someone who wants to serve an image might want to serve more images in the future so one could argue that writing a specific custom static file server that can serve only one single file with hard-coded path is somewhat shortsighted. It seems hard to imagine that anyone who searches for an answer on how to serve an image would be content with a solution that serves just a single image instead of a general solution to serve any image.
In short, the question is how to serve an image and an answer to that is to use an appropriate module to do that in a secure, preformant and reliable way that is readable, maintainable and future-proof while using the best practice of professional Node development. But I agree that a great addition to such an answer would be showing a way to implement the same functionality manually but sadly every attempt to do that has failed so far. And that is why I wrote some new examples.
After this short introduction, here are my five examples doing the job on 5 different levels of abstraction.
Every example serves files from the public
directory and supports the minumum functionality of:
index.html
as a default directory indexI tested every version on Node versions 4, 5, 6 and 7.
express.static
This version uses the express.static
built-in middleware of the express
module.
This example has the most functionality and the least amount of code.
var path = require('path');
var express = require('express');
var app = express();
var dir = path.join(__dirname, 'public');
app.use(express.static(dir));
app.listen(3000, function () {
console.log('Listening on http://localhost:3000/');
});
express
This version uses the express
module but without the express.static
middleware. Serving static files is implemented as a single route handler using streams.
This example has simple path traversal countermeasures and supports a limited set of most common MIME types.
var path = require('path');
var express = require('express');
var app = express();
var fs = require('fs');
var dir = path.join(__dirname, 'public');
var mime = {
html: 'text/html',
txt: 'text/plain',
css: 'text/css',
gif: 'image/gif',
jpg: 'image/jpeg',
png: 'image/png',
svg: 'image/svg+xml',
js: 'application/javascript'
};
app.get('*', function (req, res) {
var file = path.join(dir, req.path.replace(/\/$/, '/index.html'));
if (file.indexOf(dir + path.sep) !== 0) {
return res.status(403).end('Forbidden');
}
var type = mime[path.extname(file).slice(1)] || 'text/plain';
var s = fs.createReadStream(file);
s.on('open', function () {
res.set('Content-Type', type);
s.pipe(res);
});
s.on('error', function () {
res.set('Content-Type', 'text/plain');
res.status(404).end('Not found');
});
});
app.listen(3000, function () {
console.log('Listening on http://localhost:3000/');
});
connect
This version uses the connect
module which is a one level of abstraction lower than express
.
This example has similar functionality to the express
version but using slightly lower-lever APIs.
var path = require('path');
var connect = require('connect');
var app = connect();
var fs = require('fs');
var dir = path.join(__dirname, 'public');
var mime = {
html: 'text/html',
txt: 'text/plain',
css: 'text/css',
gif: 'image/gif',
jpg: 'image/jpeg',
png: 'image/png',
svg: 'image/svg+xml',
js: 'application/javascript'
};
app.use(function (req, res) {
var reqpath = req.url.toString().split('?')[0];
if (req.method !== 'GET') {
res.statusCode = 501;
res.setHeader('Content-Type', 'text/plain');
return res.end('Method not implemented');
}
var file = path.join(dir, reqpath.replace(/\/$/, '/index.html'));
if (file.indexOf(dir + path.sep) !== 0) {
res.statusCode = 403;
res.setHeader('Content-Type', 'text/plain');
return res.end('Forbidden');
}
var type = mime[path.extname(file).slice(1)] || 'text/plain';
var s = fs.createReadStream(file);
s.on('open', function () {
res.setHeader('Content-Type', type);
s.pipe(res);
});
s.on('error', function () {
res.setHeader('Content-Type', 'text/plain');
res.statusCode = 404;
res.end('Not found');
});
});
app.listen(3000, function () {
console.log('Listening on http://localhost:3000/');
});
http
This version uses the http
module which is the lowest-level API for HTTP in Node.
This example has similar functionality to the connect
version but using even more lower-level APIs.
var path = require('path');
var http = require('http');
var fs = require('fs');
var dir = path.join(__dirname, 'public');
var mime = {
html: 'text/html',
txt: 'text/plain',
css: 'text/css',
gif: 'image/gif',
jpg: 'image/jpeg',
png: 'image/png',
svg: 'image/svg+xml',
js: 'application/javascript'
};
var server = http.createServer(function (req, res) {
var reqpath = req.url.toString().split('?')[0];
if (req.method !== 'GET') {
res.statusCode = 501;
res.setHeader('Content-Type', 'text/plain');
return res.end('Method not implemented');
}
var file = path.join(dir, reqpath.replace(/\/$/, '/index.html'));
if (file.indexOf(dir + path.sep) !== 0) {
res.statusCode = 403;
res.setHeader('Content-Type', 'text/plain');
return res.end('Forbidden');
}
var type = mime[path.extname(file).slice(1)] || 'text/plain';
var s = fs.createReadStream(file);
s.on('open', function () {
res.setHeader('Content-Type', type);
s.pipe(res);
});
s.on('error', function () {
res.setHeader('Content-Type', 'text/plain');
res.statusCode = 404;
res.end('Not found');
});
});
server.listen(3000, function () {
console.log('Listening on http://localhost:3000/');
});
net
This version uses the net
module which is the lowest-level API for TCP sockets in Node.
This example has some of the functionality of the http
version but the minimal and incomplete HTTP protocol has been implemented from scratch. Since it doesn't support chunked encoding it loads the files into memory before serving them to know the size before sending a response because statting the files and then loading would introduce a race condition.
var path = require('path');
var net = require('net');
var fs = require('fs');
var dir = path.join(__dirname, 'public');
var mime = {
html: 'text/html',
txt: 'text/plain',
css: 'text/css',
gif: 'image/gif',
jpg: 'image/jpeg',
png: 'image/png',
svg: 'image/svg+xml',
js: 'application/javascript'
};
var server = net.createServer(function (con) {
var input = '';
con.on('data', function (data) {
input += data;
if (input.match(/\n\r?\n\r?/)) {
var line = input.split(/\n/)[0].split(' ');
var method = line[0], url = line[1], pro = line[2];
var reqpath = url.toString().split('?')[0];
if (method !== 'GET') {
var body = 'Method not implemented';
con.write('HTTP/1.1 501 Not Implemented\n');
con.write('Content-Type: text/plain\n');
con.write('Content-Length: '+body.length+'\n\n');
con.write(body);
con.destroy();
return;
}
var file = path.join(dir, reqpath.replace(/\/$/, '/index.html'));
if (file.indexOf(dir + path.sep) !== 0) {
var body = 'Forbidden';
con.write('HTTP/1.1 403 Forbidden\n');
con.write('Content-Type: text/plain\n');
con.write('Content-Length: '+body.length+'\n\n');
con.write(body);
con.destroy();
return;
}
var type = mime[path.extname(file).slice(1)] || 'text/plain';
var s = fs.readFile(file, function (err, data) {
if (err) {
var body = 'Not Found';
con.write('HTTP/1.1 404 Not Found\n');
con.write('Content-Type: text/plain\n');
con.write('Content-Length: '+body.length+'\n\n');
con.write(body);
con.destroy();
} else {
con.write('HTTP/1.1 200 OK\n');
con.write('Content-Type: '+type+'\n');
con.write('Content-Length: '+data.byteLength+'\n\n');
con.write(data);
con.destroy();
}
});
}
});
});
server.listen(3000, function () {
console.log('Listening on http://localhost:3000/');
});

The above method works good.
Another method (I am assuming web here) is to create your page. Add controls to the page. Then while in design mode go to: Tools > Generate Local Resource. A resource file will automatically appear in the solution with all the controls in the page mapped in the resource file.
To create resources for other languages, append the 4 character language to the end of the file name, before the extension (Account.aspx.en-US.resx, Account.aspx.es-ES.resx...etc).
To retrieve specific entries in the code-behind, simply call this method: GetLocalResourceObject([resource entry key/name])
.
Normally speaking you'd use a DB manager application like pgAdmin, browse to the object you're interested in, and right click your way to "script as create" or similar.
Are you trying to do this... without a management app?
Couple of ways. Firstly, if you're adding a row each time a [de]activation occurs, you can set the column default to GETDATE() and not set the value in the insert. Otherwise,
UPDATE TableName SET [ColumnName] = GETDATE() WHERE UserId = @userId
So, your input is 'dan|warrior|54' and you want "warrior". You do this like so:
>>> dan = 'dan|warrior|54'
>>> dan.split('|')[1]
"warrior"

The content of the table/tables in PostgreSQL database can be deleted in several ways.
Deleting table content using sql:
Deleting content of one table:
TRUNCATE table_name;
DELETE FROM table_name;
Deleting content of all named tables:
TRUNCATE table_a, table_b, …, table_z;
Deleting content of named tables and tables that reference to them (I will explain it in more details later in this answer):
TRUNCATE table_a, table_b CASCADE;
Deleting table content using pgAdmin:
Deleting content of one table:
Right click on the table -> Truncate
Deleting content of table and tables that reference to it:
Right click on the table -> Truncate Cascaded
Difference between delete and truncate:
From the documentation:
DELETE deletes rows that satisfy the WHERE clause from the specified table. If the WHERE clause is absent, the effect is to delete all rows in the table. http://www.postgresql.org/docs/9.3/static/sql-delete.html
TRUNCATE is a PostgreSQL extension that provides a faster mechanism to remove all rows from a table. TRUNCATE quickly removes all rows from a set of tables. It has the same effect as an unqualified DELETE on each table, but since it does not actually scan the tables it is faster. Furthermore, it reclaims disk space immediately, rather than requiring a subsequent VACUUM operation. This is most useful on large tables. http://www.postgresql.org/docs/9.1/static/sql-truncate.html
Working with table that is referenced from other table:
When you have database that has more than one table the tables have probably relationship. As an example there are three tables:
create table customers (
customer_id int not null,
name varchar(20),
surname varchar(30),
constraint pk_customer primary key (customer_id)
);
create table orders (
order_id int not null,
number int not null,
customer_id int not null,
constraint pk_order primary key (order_id),
constraint fk_customer foreign key (customer_id) references customers(customer_id)
);
create table loyalty_cards (
card_id int not null,
card_number varchar(10) not null,
customer_id int not null,
constraint pk_card primary key (card_id),
constraint fk_customer foreign key (customer_id) references customers(customer_id)
);
And some prepared data for these tables:
insert into customers values (1, 'John', 'Smith');
insert into orders values
(10, 1000, 1),
(11, 1009, 1),
(12, 1010, 1);
insert into loyalty_cards values (100, 'A123456789', 1);
Table orders references table customers and table loyalty_cards references table customers. When you try to TRUNCATE / DELETE FROM the table that is referenced by other table/s (the other table/s has foreign key constraint to the named table) you get an error. To delete content from all three tables you have to name all these tables (the order is not important)
TRUNCATE customers, loyalty_cards, orders;
or just the table that is referenced with CASCADE key word (you can name more tables than just one)
TRUNCATE customers CASCADE;
The same applies for pgAdmin. Right click on customers table and choose Truncate Cascaded.
Add multiDexEnabled in gradle (app level) like this:
defaultConfig {
...
...
multiDexEnabled true
}
When you stop an instance, it is 'deleted'. As such there's nothing to be charged for. If you have an Elastic IP or EBS, then you'll be charged for those - but nothing related to the instance itself.
The REST camp have some guiding principles that we can use to standardize the way we use HTTP verbs. This is helpful when building RESTful API's as you are doing.
In a nutshell: GET should be Read Only i.e. have no effect on server state. POST is used to create a resource on the server. PUT is used to update or create a resource. DELETE is used to delete a resource.
In other words, if your API action changes the server state, REST advises us to use POST/PUT/DELETE, but not GET.
User agents usually understand that doing multiple POSTs is bad and will warn against it, because the intent of POST is to alter server state (eg. pay for goods at checkout), and you probably don't want to do that twice!
Compare to a GET which you can do an often as you like (idempotent).

PK: A single key that is unique and not-null. It is one of the candidate keys.
Foreign Key: FK is a key in one table (child) that uniquely identifies a row of another table (parent). A FK is not-unique in the child table. It is a candidate key in the parent table. Referential integrity is maintained as the value in FK is present as a value in PK in parent table else it is NULL.
Unique Key: A unique key that may or may not be NULL
Natural key: PK in OLTP. It may be a PK in OLAP.
Surrogate Key: It is the Surrogate PK in OLAP acting as the substitute of the PK in OLTP. Artificial key generated internally in OLAP.
Composite Key: PK made up of multiple attributes
SuperKey: A key that can be uniquely used to identify a database record, that may contain extra attributes that are not necessary to uniquely identify records.
Candidate Key: A candidate key can be uniquely used to identify a database record without any extraneous data. They are Not Null and unique. It is a minimal super-key.
Alternate Key: A candidate key that is not the primary key is called an alternate key.
Candidate Key/s with Extraneous data: Consider that can be used to identify a record in the Employee table but candidate key alone is sufficient for this task. So becomes the extraneous data.
Note that the PK, Foreign Key, Unique Key, Natural key, Surrogate Key, Composite Key are defined as Database objects; where the Natural key is a PK in the OLTP and could be a PK in the target OLAP. For the rest of the keys, it's up to the DB designer/architect to decide whether unique/not-null/referential integrity constraints need to enforced or not.
Below I have tried to use set theory to simplify the representation of the membership of the keys w.r.t. each other.
key = { All of the below keys }
PK = { PK }
Foreign Key = { Key with Not Null constraint }
Unique Key = { {Candidate Key/s}, {attributes containing NULL} }
Natural key = { PK }
Surrogate Key = { PK }
Composite Key = { PK }
Super Key = { {Candidate Key/s}, {Candidate Key/s with Extraneous data} }
Candidate Key = { PK, {Alternate Key/s} }
Alternate Key = { {Candidate Keys} - PK }
Candidate Key/s with Extraneous data = { }
I have summarized it below:

You should have a look at moment
which is a python port of the excellent js lib momentjs
.
One advantage of it is the support of ISO 8601
strings formats, as well as a generic "% format" :
import moment
time_string='2012-10-09T19:00:55Z'
m = moment.date(time_string, '%Y-%m-%dT%H:%M:%SZ')
print m.format('YYYY-M-D H:M')
print m.weekday
Result:
2012-10-09 19:10

IMO extremely important rule of thumb for your client side js code is to keep separated the data handling and ui building logic into different funcs, which is also valid for axios data fetching ... in this way your control flow and error handlings will be much more simple and easier to manage, as it could be seen from this ok fetch
and this NOK fetch
<script src="https://unpkg.com/axios/dist/axios.min.js"></script>
<script>
function getUrlParams (){
var url_params = new URLSearchParams();
if( window.location.toString().indexOf("?") != -1) {
var href_part = window.location.search.split('?')[1]
href_part.replace(/([^=&]+)=([^&]*)/g,
function(m, key, value) {
var attr = decodeURIComponent(key)
var val = decodeURIComponent(value)
url_params.append(attr,val);
});
}
// for(var pair of url_params.entries()) { consolas.log(pair[0]+ '->'+ pair[1]); }
return url_params ;
}
function getServerData (url, urlParams ){
if ( typeof url_params == "undefined" ) { urlParams = getUrlParams() }
return axios.get(url , { params: urlParams } )
.then(response => {
return response ;
})
.catch(function(error) {
console.error ( error )
return error.response;
})
}
// Action !!!
getServerData(url , url_params)
.then( response => {
if ( response.status === 204 ) {
var warningMsg = response.statusText
console.warn ( warningMsg )
return
} else if ( response.status === 404 || response.status === 400) {
var errorMsg = response.statusText // + ": " + response.data.msg // this is my api
console.error( errorMsg )
return ;
} else {
var data = response.data
var dataType = (typeof data)
if ( dataType === 'undefined' ) {
var msg = 'unexpected error occurred while fetching data !!!'
// pass here to the ui change method the msg aka
// showMyMsg ( msg , "error")
} else {
var items = data.dat // obs this is my api aka "dat" attribute - that is whatever happens to be your json key to get the data from
// call here the ui building method
// BuildList ( items )
}
return
}
})

I have problems with set password too. And find answer at official site
SET PASSWORD FOR 'root'@'localhost' = 'your_password';
@roblll had it right. But for those of you who didn't want to dig for the answer, here it is:
Note that there's a binding for HTTP with the port you intend to use for https.
//Change this:
<binding protocol="http" bindingInformation="*:44300:localhost" />
//to this:
<binding protocol="https" bindingInformation="*:44300:localhost" />
Keep in mind, Visual Studio might have supplied different ports than you expected. Just make sure that the ports in the binding correspond to what's in the Web tab of your project's properties.

For the correct and efficient computation of the hash value of a file (in Python 3):
'b'
to the filemode) to avoid character encoding and line-ending conversion issues.readinto()
to avoid buffer churning.Example:
import hashlib
def sha256sum(filename):
h = hashlib.sha256()
b = bytearray(128*1024)
mv = memoryview(b)
with open(filename, 'rb', buffering=0) as f:
for n in iter(lambda : f.readinto(mv), 0):
h.update(mv[:n])
return h.hexdigest()
This is my simple solution:
import time
def progress(_cur, _max):
p = round(100*_cur/_max)
b = f"Progress: {p}% - ["+"."*int(p/5)+" "*(20-int(p/5))+"]"
print(b, end="\r")
# USAGE:
for i in range(0,101):
time.sleep(0.1)
progress(i,100)
print("..."*5, end="\r")
print("Done")

This can also be a issue when you enter wrong password for your sign key.
To be able to use the jobParameters I think you need to define your reader as scope 'step', but I am not sure if you can do it using annotations.
Using xml-config it would go like this:
<bean id="foo-readers" scope="step"
class="...MyReader">
<property name="fileName" value="#{jobExecutionContext['fileName']}" />
</bean>
See further at the Spring Batch documentation.
Perhaps it works by using @Scope
and defining the step scope in your xml-config:
<bean class="org.springframework.batch.core.scope.StepScope" />
The desired result can be obtained using IGrouping, which represents a collection of objects that have a common key in this case a GroupID
var newCustomerList = CustomerList.GroupBy(u => u.GroupID)
.Select(group => new { GroupID = group.Key, Customers = group.ToList() })
.ToList();
What you're looking at is called a Ternary Operator, and you can find the PHP implementation here. It's an if else
statement.
if (isset($_GET['something']) == true) {
thing = isset($_GET['something']);
} else {
thing = "";
}
Create black png with lets say 50% transparency. Overlay this on mouseover.
You can use this method also it will act like that
thadari=[1,2,3,4,5,6]
#Front Two(Left)
print(thadari[:2])
[1,2]
#Last Two(Right)# edited
print(thadari[-2:])
[5,6]
#mid
mid = len(thadari) //2
lefthalf = thadari[:mid]
[1,2,3]
righthalf = thadari[mid:]
[4,5,6]
Hope it will help

Here is something I tried to simulate for you.

Created a filter that you also can use in 'ng-repeat'
app.filter('getById', function() {
return function(input, id) {
var i=0, len=input.length;
for (; i<len; i++) {
if (+input[i].id == +id) {
return input[i];
}
}
return null;
}
});
Usage in controller:
app.controller('SomeController', ['$scope', '$filter', function($scope, $filter) {
$scope.fish = [{category:'freshwater', id:'1', name: 'trout', more:'false'}, {category:'freshwater', id:'2', name:'bass', more:'false'}]
$scope.showdetails = function(fish_id){
var found = $filter('getById')($scope.fish, fish_id);
console.log(found);
$scope.selected = JSON.stringify(found);
}
}]);

We use this code to center the Bootstrap modal dialogs when they open. I haven't had any issue with them on iOS while using this but I'm not sure if it will work for Android.
$('.modal').on('show', function(e) {
var modal = $(this);
modal.css('margin-top', (modal.outerHeight() / 2) * -1)
.css('margin-left', (modal.outerWidth() / 2) * -1);
return this;
});
Instead of the *
selector you can use the :not(selector)
with the >
selector and set something that definitely wont be a child.
Edit: I thought it would be faster but it turns out I was wrong. Disregard.
Example:
.container > :not(marquee){
color:red;
}
<div class="container">
<p></p>
<span></span>
<div>
One way is to replace the double quotes in the HTML with single quotes but using double quotes has become the standard convention for attribute values in HTML.
The better option is to escape the double quotes in json and other characters that need to be escaped.
You can get some more details about escaping here: Where can I find a list of escape characters required for my JSON ajax return type?
You guessed right MySQL have limitation for size of data, you need to break your query in small group of records or you can Change your max_allowed_packet by using SET GLOBAL max_allowed_packet=524288000;
You could add another empty layout below that one and set them both to have the same layout weight. They should get 50% of the space each.
public void run() {
byte[] buffer = new byte[256];
int bytes;
while (true) {
try {
bytes = mmInStream.read(buffer);
mHandler.obtainMessage(RECIEVE_MESSAGE, bytes, -1, buffer).sendToTarget();
} catch (IOException e) {
break;
}
}
}
String[] str = s.split("[^a-zA-Z]+");
1) You can use the !important
rule, like this:
.selected
{
background-color:red !important;
}
See http://www.w3.org/TR/CSS2/cascade.html#important-rules for more info.
2) In your example you can also get the red background by using ul.nav li.selected
instead of just .selected
. This makes the selector more specific.
See http://www.w3.org/TR/CSS2/cascade.html#specificity for more info.
Slightly modified version of Sebastian's answer using find
instead of du
(to exclude file-size-related overhead that du
has to perform and that is never used):
find ./ -mindepth 2 -type f | cut -d/ -f2 | sort | uniq -c | sort -nr
-mindepth 2
parameter is used to exclude files in current directory. If you remove it, you'll see a bunch of lines like the following:
234 dir1
123 dir2
1 file1
1 file2
1 file3
...
1 fileN
(much like the du
-based variant does)
If you do need to count the files in current directory as well, use this enhanced version:
{ find ./ -mindepth 2 -type f | cut -d/ -f2 | sort && find ./ -maxdepth 1 -type f | cut -d/ -f1; } | uniq -c | sort -nr
The output will be like the following:
234 dir1
123 dir2
42 .
If you must have GitHub, there is the enterprise version as already mentioned.
If you want to look for alternatives for running a central git server for your company, you can try Gitolite.

Using Post call, worked for me.
RestClient restClient = new RestClient();
RestRequest request = new RestRequest();
request.AddQueryParameter("client_id", "value");
request.AddQueryParameter("client_secret", "value");
request.AddQueryParameter("grant_type", "refresh_token");
request.AddQueryParameter("refresh_token", "value");
restClient.BaseUrl = new System.Uri("https://oauth2.googleapis.com/token");
restClient.Post(request);
Without using 'length' you can do it like this:
if ($('input[type=checkbox]').is(":checked")) {
//any one is checked
}
else {
//none is checked
}
I think you need a service
that handle the authentication process (and its storage).
In this service you'll need some basic methods :
isAuthenticated()
login()
logout()
This service should be injected in your controllers of each module :
service.isAuthenticated()
method) . if not, redirect to /loginservice.login()
methodA good and robust example for this behavior is the project angular-app and specifically its security module which is based over the awesome HTTP Auth Interceptor Module
Hope this helps
This is a bit late but I ran into something interesting that seems important to contribute.
I accidentally wrote this code, and it seems to work:
require 'yaml'
CONFIG_FILE = ENV['CONFIG_FILE'] # path to a JSON config file
configs = YAML.load_file("#{CONFIG_FILE}")
puts configs['desc']['someKey']
I was surprised to see it works since I am using the YAML library, but it works.
The reason why it is important is that yaml
comes built-in with Ruby so there's no gem install.
I am using versions 1.8.x and 1.9.x - so the json
library is not built in, but it is in version 2.x.
So technically - this is the easiest way to extract the data in version lower than 2.0.
try
public void PrintGeneric<T>(T test) where T: ITest
{
Console.WriteLine("Generic : " + test.@var);
}
as @Ash Burlaczenko has said you cant name a variable after a keyword, if you reallllly want this prefix with @ symbol to escape the keyword
You should simply return your object, and shouldn't be concerned about whether its XML or JSON. It is the client responsibility to request JSON or XML from the web api. For example, If you make a call using Internet explorer then the default format requested will be Json and the Web API will return Json. But if you make the request through google chrome, the default request format is XML and you will get XML back.
If you make a request using Fiddler then you can specify the Accept header to be either Json or XML.
Accept: application/xml
You may wanna see this article: Content Negotiation in ASP.NET MVC4 Web API Beta – Part 1
EDIT: based on your edited question with code:
Simple return list of string, instead of converting it to XML. try it using Fiddler.
public List<string> Get(int tenantID, string dataType, string ActionName)
{
List<string> SQLResult = MyWebSite_DataProvidor.DB.spReturnXMLData("SELECT * FROM vwContactListing FOR XML AUTO, ELEMENTS").ToList();
return SQLResult;
}
For example if your list is like:
List<string> list = new List<string>();
list.Add("Test1");
list.Add("Test2");
list.Add("Test3");
return list;
and you specify Accept: application/xml
the output will be:
<ArrayOfstring xmlns:i="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://schemas.microsoft.com/2003/10/Serialization/Arrays">
<string>Test1</string>
<string>Test2</string>
<string>Test3</string>
</ArrayOfstring>
and if you specify 'Accept: application/json' in the request then the output will be:
[
"Test1",
"Test2",
"Test3"
]
So let the client request the content type, instead of you sending the customized xml.
The easiest way I've found to place objects on the left is using FlowLayout.
JPanel panel = new JPanel(new FlowLayout(FlowLayout.LEFT));
adding a component normally to this panel will place it on the left
NSMutableAttributedString *attributedString = [[NSMutableAttributedString alloc] initWithString:strSomeTextWithLinks];
NSDictionary *linkAttributes = @{NSForegroundColorAttributeName: [UIColor redColor],
NSUnderlineColorAttributeName: [UIColor blueColor],
NSUnderlineStyleAttributeName: @(NSUnderlinePatternSolid)};
customTextView.linkTextAttributes = linkAttributes; // customizes the appearance of links
textView.attributedText = attributedString;
WHERE AND SELECT Condition In Array Format Laravel
use DB;
$conditions = array(
array('email', '=', '[email protected]')
);
$selected = array('id','name','email','mobile','created');
$result = DB::table('users')->select($selected)->where($conditions)->get();

}
-(void)application:(UIApplication *)application
didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings {
if (notificationSettings.types) {
NSLog(@"user allowed notifications");

[alert show];
// show alert here

}
In the last answer, you don't need to make a list from numbers; it is already a list:
numbers = [1, 2, 3]
numsum = sum(numbers)
print(numsum)

For people using private GitLabs, here's a snippet that may help: https://gist.github.com/MicahParks/1ba2b19c39d1e5fccc3e892837b10e21
Also pasted below:
The go
command line tool needs to be able to fetch dependencies from your private GitLab, but authenticaiton is required.
This assumes your private GitLab is hosted at privategitlab.company.com
.
The following environment variables are recommended:
export GO111MODULE=on
export GOPRIVATE=privategitlab.company.com
The above lines might fit best in your shell startup, like a ~/.bashrc
.
GO111MODULE=on
tells Golang command line tools you are using modules. I have not tested this with projects not using
Golang modules on a private GitLab.
GOPRIVATE=privategitlab.company.com
tells Golang command line tools to not use public internet resources for the hostnames
listed (like the public module proxy).
To future proof these instructions, please follow this guide from the GitLab docs.
I know that the read_api
scope is required for Golang command line tools to work, and I may suspect read_repository
as
well, but have not confirmed this.
~/.netrc
In order for the Golang command line tools to authenticate to GitLab, a ~/.netrc
file is best to use.
To create the file if it does not exist, run the following commands:
touch ~/.netrc
chmod 600 ~/.netrc
Now edit the contents of the file to match the following:
machine privategitlab.company.com login USERNAME_HERE password TOKEN_HERE
Where USERNAME_HERE
is replaced with your GitLab username and TOKEN_HERE
is replaced with the access token aquired in the
previous section.
Do not set up a global git configuration with something along the lines of this:
git config --global url."[email protected]:".insteadOf "https://privategitlab.company.com"
I beleive at the time of writing this, the SSH git is not fully supported by Golang command line tools and this may cause
conflicts with the ~/.netrc
.
For regular use of the git
tool, not the Golang command line tools, it's convient to have a ~/.ssh/config
file set up.
In order to do this, run the following commands:
mkdir ~/.ssh
chmod 700 ~/.ssh
touch ~/.ssh/config
chmod 600 ~/.ssh/config
Please note the permissions on the files and directory above are essentail for SSH to work in it's default configuration on most Linux systems.
Then, edit the ~/.ssh/config
file to match the following:
Host privategitlab.company.com
Hostname privategitlab.company.com
User USERNAME_HERE
IdentityFile ~/.ssh/id_rsa
Please note the spacing in the above file matters and will invalidate the file if it is incorrect.
Where USERNAME_HERE
is your GitLab username and ~/.ssh/id_rsa
is the path to your SSH private key in your file system.
You've already uploaded its public key to GitLab. Here are some instructions.

Think of a table of vehicles with an integer Primary Key.
The registration number would be a candidate key.
In the real world registration numbers are subject change so it depends somewhat on the circumstances what might qualify as a candidate key.
You can use this code block for JFrame background color.
JFrame frame = new JFrame("Frame BG color");
frame.setLayout(null);
frame.setSize(1000, 650);
frame.getContentPane().setBackground(new Color(5, 65, 90));
frame.setLocationRelativeTo(null);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setResizable(false);
frame.setVisible(true);
Alternatively, if you just want to convert one particular row to uppercase, use the code below:
df[[1]] <- toupper(df[[1]])
This is how to get JavaScriptSerializer available in your application, targetting .NET 4.0
(full)
using System.Web.Script.Serialization;
This should allow you to create a new JavaScriptSerializer
object!
following Donald's comment:
This variable applies when binary logging is enabled.
All I had to do was:
That step out that import problem.
(Then I'll review the programmer's code to suggest an improvement)
For me, in Python 3, it's working simply in this way:
keep = keep.union((0,1,2,3,4,5,6,7,8,9,10))
I don't know if it may be correct...
The easiest way to solve this problem is to use a command line. Type this command
rm -R .git/
OR
rm -rf .git/
I am working with a Python code for a REST API, so this is for those who are working on similar projects.
I extract data from an URL using a POST request and the raw output is JSON. For some reason the output is already a dictionary, not a list, and I'm able to refer to the nested dictionary keys right away, like this:
datapoint_1 = json1_data['datapoints']['datapoint_1']
where datapoint_1 is inside the datapoints dictionary.
Install
npm i graph-fs
Use
const {Node} = require("graph-fs");
const directory = new Node("/path/to/directory");
directory.clear(); // <--
The shortest way would be:
$("#" + row_id)
Limiting the search to the body doesn't have any benefit.
Also, you should consider renaming your id
s to something more meaningful (and HTML compliant as per Paolo's answer), especially if you have another set of data that needs to be named as well.
Could you not 'stringify' your object...then use sessionStorage.setItem()
to store that string representation of your object...then when you need it sessionStorage.getItem()
and then use $.parseJSON()
to get it back out?

As of September 2016
Firefox 48.0
and selenium==2.53.6
work fine without any errors
To upgrade firefox on Ubuntu 14.04
only
sudo apt-get update
sudo apt-get upgrade firefox
Short answer to first question: yes.
Longer answer: maybe; it depends on whether the build process for SVMLight behaves itself on 64-bit windows.
Final note: that call to System.loadLibrary is silly. Either call System.load with a full pathname or let it search java.library.path.
<?php
$j=1;
?>
<script>
var i = "<?php echo $j; ?>";
//Do something
</script>
<?php
echo $j;
?>
This is the easiest way of passing a php variable to javascript without Ajax.
You can also use something like this:
var i = "<?php echo json_encode($j); ?>";
This said to be safer or more secure. i think
I just came across this same problem, where it was all working fine, up until the point I had an includes within another includes.
require_once '../script/pdocrud.php'; //This worked fine up until I had an includes within another includes, then I got this error:
Fatal error: require_once() [function.require]: Failed opening required '../script/pdocrud.php' (include_path='.:/opt/php52/lib/php')
Solution 1. (undesired hardcoding of my public html folder name, but it works):
require_once $_SERVER["DOCUMENT_ROOT"] . '/orders.simplystyles.com/script/pdocrud.php';
Solution 2. (undesired comment above about DIR only working since php 5.3, but it works):
require_once __DIR__. '/../script/pdocrud.php';
Solution 3. (I can't see any downsides, and it works perfectly in my php 5.3):
require_once dirname(__FILE__). '/../script/pdocrud.php';
Here's my idea on how to fix this:
j = 19
def calc(y):
global j
try:
j = j + 8 - y
x = int(y/j) # this will eventually raise DIV/0 when j=0
print("i = ", str(y), " j = ", str(j), " x = ", str(x))
except:
j = j + 1 # when the exception happens, increment "j" and retry
calc(y)
for i in range(50):
calc(i)
This will do the job:
<div style="position:absolute; right:0;">Hello world</div>

If you check Dockerfile from containers, for example fballiano/magento2-apache-php
you'll see that at the end of his file he adds the following command: while true; do sleep 1; done
Now, what I recommend, is that you do this
docker container ls --all | grep 127
Then, you will see if your docker image had an error, if it exits with 0, then it probably needs one of these commands that will sleep forever.
Try to follow the advice you see on the screen, and first reset your master's HEAD to the commit it expects.
git update-ref refs/heads/master b918ac16a33881ce00799bea63d9c23bf7022d67
Then, abort the rebase again.
it's so easy...converting a date to calendar like this:
Calendar cal=Calendar.getInstance();
DateFormat format=new SimpleDateFormat("yyyy/mm/dd");
format.format(date);
cal=format.getCalendar();
This flexbox principle also works horizontally
During calculations of flex bases and flexible lengths, auto margins
are treated as 0.
Prior to alignment via justify-content and
align-self, any positive free space is distributed to auto margins in
that dimension.
Setting an automatic left margin for the Last Item will do the work.
.last-item {
margin-left: auto;
}
Code Example:
.container {_x000D_
display: flex;_x000D_
width: 400px;_x000D_
outline: 1px solid black;_x000D_
}_x000D_
_x000D_
p {_x000D_
height: 50px;_x000D_
width: 50px;_x000D_
margin: 5px;_x000D_
background-color: blue;_x000D_
}_x000D_
_x000D_
.last-item {_x000D_
margin-left: auto;_x000D_
}
_x000D_
<div class="container">_x000D_
<p></p>_x000D_
<p></p>_x000D_
<p></p>_x000D_
<p class="last-item"></p>_x000D_
</div>
_x000D_
This can be very useful for Desktop Footers.
As Envato did here with the company logo.
To position horizontally center you can say width: 50%; margin: auto;
. As far as I know, that's cross browser. For vertical alignment you can try vertical-align:middle;
, but it may only work in relation to text. It's worth a try though.
I run into a similar problem while running a Unit Test. Console.WriteLine()
did not write anything into the VS Output Window.
Using System.Diagnostics.Debug.WriteLine()
solved the problem.
I removed old AppleWWDRCA, downloaded and installed AppleWWDRCA, but problem remained. I also, checked my distribution and development certificates from Keychain Access, and see below error;
"This certificate has an invalid issuer."
Then,
This fixed certificate problem.
Since old certificates revoked, existing provisioning profiles become invalid. To fix this;
I hope this helps.
Here is one case that worked for me if we need to convert .cer to .crt, though both of them are contextually same
openssl pkcs12 -in identity.p12 -nokeys -out mycertificate.crt
where we should have a valid private key (identity.p12) PKCS 12 format, this one i generated from keystore (.jks file) provided by CA (Certification Authority) who created my certificate.
Implementation with Guzzle library:
use GuzzleHttp\Client;
use GuzzleHttp\RequestOptions;
$httpClient = new Client();
$response = $httpClient->post(
'https://postman-echo.com/post',
[
RequestOptions::BODY => 'POST raw request content',
RequestOptions::HEADERS => [
'Content-Type' => 'application/x-www-form-urlencoded',
],
]
);
echo(
$response->getBody()->getContents()
);
PHP CURL extension:
$curlHandler = curl_init();
curl_setopt_array($curlHandler, [
CURLOPT_URL => 'https://postman-echo.com/post',
CURLOPT_RETURNTRANSFER => true,
/**
* Specify POST method
*/
CURLOPT_POST => true,
/**

*/
CURLOPT_POSTFIELDS => 'POST raw request content',
]);
$response = curl_exec($curlHandler);
curl_close($curlHandler);
echo($response);
It far easier to use the scripting runtime which is installed by default on Windows
Just go project Reference and check Microsoft Scripting Runtime and click OK.
Then you can use this code which is way better than the default file commands
Dim FSO As FileSystemObject
Dim TS As TextStream
Dim TempS As String
Dim Final As String
Set FSO = New FileSystemObject
Set TS = FSO.OpenTextFile("C:\Clients\Converter\Clockings.mis", ForReading)
'Use this for reading everything in one shot
Final = TS.ReadAll
'OR use this if you need to process each line
Do Until TS.AtEndOfStream
TempS = TS.ReadLine
Final = Final & TempS & vbCrLf
Loop
TS.Close
Set TS = FSO.OpenTextFile("C:\Clients\Converter\2.txt", ForWriting, True)
TS.Write Final
TS.Close
Set TS = Nothing
Set FSO = Nothing
As for what is wrong with your original code here you are reading each line of the text file.
Input #iFileNo, sFileText
Then here you write it out
Write #iFileNo, sFileText
sFileText is a string variable so what is happening is that each time you read, you just replace the content of sFileText with the content of the line you just read.
So when you go to write it out, all you are writing is the last line you read, which is probably a blank line.
Dim sFileText As String
Dim sFinal as String
Dim iFileNo As Integer
iFileNo = FreeFile
Open "C:\Clients\Converter\Clockings.mis" For Input As #iFileNo
Do While Not EOF(iFileNo)
Input #iFileNo, sFileText
sFinal = sFinal & sFileText & vbCRLF
Loop
Close #iFileNo
iFileNo = FreeFile 'Don't assume the last file number is free to use
Open "C:\Clients\Converter\2.txt" For Output As #iFileNo
Write #iFileNo, sFinal
Close #iFileNo
Note you don't need to do a loop to write. sFinal contains the complete text of the File ready to be written at one shot. Note that input reads a LINE at a time so each line appended to sFinal needs to have a CR and LF appended at the end to be written out correctly on a MS Windows system. Other operating system may just need a LF (Chr$(10)).
If you need to process the incoming data then you need to do something like this.
Dim sFileText As String
Dim sFinal as String
Dim vTemp as Variant
Dim iFileNo As Integer
Dim C as Collection
Dim R as Collection
Dim I as Long
Set C = New Collection
Set R = New Collection
iFileNo = FreeFile
Open "C:\Clients\Converter\Clockings.mis" For Input As #iFileNo
Do While Not EOF(iFileNo)
Input #iFileNo, sFileText
C.Add sFileText
Loop
Close #iFileNo
For Each vTemp in C
Process vTemp
Next sTemp
iFileNo = FreeFile
Open "C:\Clients\Converter\2.txt" For Output As #iFileNo
For Each vTemp in R
Write #iFileNo, vTemp & vbCRLF
Next sTemp
Close #iFileNo
Since you don't want stretching (all of the other answers ignore that) you can simply set max-width and max-height like in my jsFiddle edit.
#container img {
max-height: 250px;
max-width: 250px;
}
See my example with an image that isn't a square, it doesn't stretch
You can use org.modeshape.common.text.Inflector.

String camelCase(String lowerCaseAndUnderscoredWord, boolean uppercaseFirstLetter, char... delimiterChars)
By default, this method converts strings to UpperCamelCase.

In Node.js we can do it in simple way

I did what @gbero said, and I changed the Android version number that Studio uses from 22 to 17 and it works.
I am using the backwards compatibility to build for Android ver 22 but to target 17 (idk if that's correctly said, I am still trying to figure this app stuff out) so that triggered the backwards compatibility, which afaik is what the android.support.v7.*
is. This is probably a bug with their rendering code. Not sure if clearing the cache as suggested above was needed as rendering didn't work just after invalidating the cache, it started working after I changed the version to render. If I change back to version 22, the rendering breaks, if I switch back to 17, it works again.
Search and replace when setting environment variables:

You can use -webkit-border-radius: 0;
. Like this:-
-webkit-border-radius: 0;
border: 0;
outline: 1px solid grey;
outline-offset: -1px;
This will give square corners as well as dropdown arrows. Using -webkit-appearance: none;
is not recommended as it will turn off all the styling done by Chrome.
You can try FakeHttpContext:
using (new FakeHttpContext())
{
HttpContext.Current.Session["CustomerId"] = "customer1";
}
As it's not specified if you mean the system's current date or the date held in a variable, I'll answer for latter with an example.
<?php
$dateAsString = "Wed, 11 Apr 2018 19:00:00 -0500";
// This converts it to a unix timestamp so that the date() function can work with it.
$dateAsUnixTimestamp = strtotime($dateAsString);
// Output it month is various formats according to http://php.net/date
echo date('M',$dateAsUnixTimestamp);
// Will output Apr
echo date('n',$dateAsUnixTimestamp);
// Will output 4
echo date('m',$dateAsUnixTimestamp);
// Will output 04
?>
Thanks yckart! Great contribution. I fleshed out your plugin a bit more. Added startAngle for full control and cross-browser css.
$.fn.animateRotate = function(startAngle, endAngle, duration, easing, complete){
return this.each(function(){
var elem = $(this);
$({deg: startAngle}).animate({deg: endAngle}, {
duration: duration,
easing: easing,
step: function(now){
elem.css({
'-moz-transform':'rotate('+now+'deg)',
'-webkit-transform':'rotate('+now+'deg)',
'-o-transform':'rotate('+now+'deg)',
'-ms-transform':'rotate('+now+'deg)',
'transform':'rotate('+now+'deg)'
});
},
complete: complete || $.noop
});
});
};
It depends. In a debug build, I want to see the original stack trace with as little effort as possible. In that case, "throw;" fits the bill. In a release build, however, (a) I want to log the error with the original stack trace included, and once that's done, (b) refashion the error handling to make more sense to the user. Here "Throw Exception" makes sense. It's true that rethrowing the error discards the original stack trace, but a non-developer gets nothing out of seeing stack trace information so it's okay to rethrow the error.
void TrySuspectMethod()
{
try
{
SuspectMethod();
}
#if DEBUG
catch
{
//Don't log error, let developer see
//original stack trace easily
throw;
#else
catch (Exception ex)
{
//Log error for developers and then
//throw a error with a user-oriented message
throw new Exception(String.Format
("Dear user, sorry but: {0}", ex.Message));
#endif
}
}
The way the question is worded, pitting "Throw:" vs. "Throw ex;" makes it a bit of a red-herring. The real choice is between "Throw;" and "Throw Exception," where "Throw ex;" is an unlikely special case of "Throw Exception."
I fix this by downloading sdk package called platform-tools and buid-tools using sdkmanager
. You can use sdkmanager.exe or if you are using SDK CLI, go to ~\AppData\Local\Android\sdk\tools\bin
and run this command:
sdkmanager "platform-tools" "platforms;android-26"
or
sdkmanager "build-tools;27.0.3"
or both
After that you should be able to run ionic cordova run android
or ionic build android
.
Note: globalize sdkmanager
command by adding ~\AppData\Local\Android\sdk\tools
and ~\AppData\Local\Android\sdk\tools\bin
to your environment variable.
The value 1382086394000 is probably a time value, which is the number of milliseconds since 1970-01-01T00:00:00Z. You can use it to create an ECMAScript Date object using the Date constructor:
var d = new Date(1382086394000);
How you convert that into something readable is up to you. Simply sending it to output should call the internal (and entirely implementation dependent) toString method* that usually prints the equivalent system time in a human readable form, e.g.
Fri Oct 18 2013 18:53:14 GMT+1000 (EST)
In ES5 there are some other built-in formatting options:
and so on. Note that most are implementation dependent and will be different in different browsers. If you want the same format across all browsers, you'll need to format the date yourself, e.g.:
alert(d.getDate() + '/' + (d.getMonth()+1) + '/' + d.getFullYear());
* The format of Date.prototype.toString has been standardised in ECMAScript 2018. It might be a while before it's ubiquitous across all implementations, but at least the more common browsers support it now.
You can add an alias to diff with its own pager with pager.alias, like so:
[alias]
dc = diff
dsc = diff --staged
[pager]
dc = cat
dsc = cat
This will keep the color on and use 'cat' as the pager when invoked at 'git dc'.
Also, things not to do:
--no-pager
in your alias. Git (1.8.5.2, Apple Git-48) will complain that you are trying to modify the environment.!sh
or !git
. This will bypass the environment error, above, but it will reset your working directory (for the purposes of this command) to the top-level Git directory, so any references to a local file will not work if you are already in a subdirectory of your repository.From here: http://www.anddev.org/working_with_files-t115.html
//Writing a file...
try {

* We chose MODE_WORLD_READABLE, because
* we have nothing to hide in our file */
FileOutputStream fOut = openFileOutput("samplefile.txt",
MODE_PRIVATE);
OutputStreamWriter osw = new OutputStreamWriter(fOut);
// Write the string to the file
osw.write(TESTSTRING);
/* ensure that everything is

osw.flush();
osw.close();
//Reading the file back...
/* We have to use the openFileInput()-method

FileInputStream fIn = openFileInput("samplefile.txt");
InputStreamReader isr = new InputStreamReader(fIn);
/* Prepare a char-Array that will

char[] inputBuffer = new char[TESTSTRING.length()];
// Fill the Buffer with data from the file
isr.read(inputBuffer);
// Transform the chars to a String
String readString = new String(inputBuffer);
// Check if we read back the same chars that we had written out
boolean isTheSame = TESTSTRING.equals(readString);
Log.i("File Reading stuff", "success = " + isTheSame);
} catch (IOException ioe)
{ioe.printStackTrace();}
Place your css in the following script and paste it into your CSS file.
@media screen and (-webkit-min-device-pixel-ratio:0) { your complete css style }
For example: @media screen and (-webkit-min-device-pixel-ratio:0) { container { margin-top: 120px;} }
Works like a charm.
I'm partial to scikits.statsmodels. Here an example:
import statsmodels.api as sm
import numpy as np
import matplotlib.pyplot as plt
X = np.random.rand(100)
Y = X + np.random.rand(100)*0.1
results = sm.OLS(Y,sm.add_constant(X)).fit()
print results.summary()
plt.scatter(X,Y)
X_plot = np.linspace(0,1,100)
plt.plot(X_plot, X_plot*results.params[0] + results.params[1])
plt.show()
The only tricky part is sm.add_constant(X)
which adds a columns of ones to X
in order to get an intercept term.

A JQuery approach that will eliminate needless code.
Your idea to use enumerate()
was correct.
indices = []
for i, elem in enumerate(mylist):
if 'aa' in elem:
indices.append(i)
Alternatively, as a list comprehension:
indices = [i for i, elem in enumerate(mylist) if 'aa' in elem]
int random(int min, int max) //range : [min, max]
{
static bool first = true;
if (first)
{
srand( time(NULL) ); //seeding for the first time only!
first = false;
}
return min + rand() % (( max + 1 ) - min);
}
Use HH
for 24 hour hours format:
DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss")
Or the tt
format specifier for the AM/PM
part:
DateTime.Now.ToString("yyyy-MM-dd hh:mm:ss tt")
Take a look at the custom Date and Time format strings documentation.
Just ssh'ing to the host is not enough, on Windows at least. That adds the host key to ssh/known_hosts
but the error still persists.
You need to close the git bash window and open a new one. Then the registry cache is cleared and the push/pull then works.
Another option:
UPDATE `table` SET the_col = current_timestamp
Looks odd, but works as expected. If I had to guess, I'd wager this is slightly faster than calling now()
.
How can I undo every change made to my directory after the last commit, including deleting added files, resetting modified files, and adding back deleted files?
You can undo changes to tracked files with:
git reset HEAD --hard
You can remove untracked files with:
git clean -f
You can remove untracked files and directories with:
git clean -fd
but you can't undo change to untracked files.
You can remove ignored and untracked files and directories
git clean -fdx
but you can't undo change to ignored files.
You can also set clean.requireForce
to false
:
git config --global --add clean.requireForce false
to avoid using -f
(--force
) when you use git clean
.
Are you talking about gets
?
puts "Enter A"
a = gets.chomp
puts "Enter B"
b = gets.chomp
c = a.to_i + b.to_i
puts c
Something like that?
Kernel.gets
tries to read the params found in ARGV
and only asks to console if not ARGV
found. To force to read from console even if ARGV
is not empty use STDIN.gets
