1.3.1 fixed it.
Just update your extension and you should be good to go
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")
ESLint defaults to ES5 syntax-checking. You'll want to override to the latest well-supported version of JavaScript.
Try adding a .eslintrc
file to your project. Inside it:
{
"parserOptions": {
"ecmaVersion": 2017
},
"env": {
"es6": true
}
}
Hopefully this helps.
EDIT: I also found this example .eslintrc
which might help.
Setting 700 to .ssh and 600 to authorized_keys solved the issue.
chmod 700 /root/.ssh
chmod 600 /root/.ssh/authorized_keys
Try using this command. See the example given below:
df.loc[len(df)] = ['Product 9',99,9.99,8.88,1.11]
df
If you use MAMP, you might have to set the socket: unix_socket: /Applications/MAMP/tmp/mysql/mysql.sock
I ran into the exact same problem under identical circumstances. I don't have the tnsnames.ora file, and I wanted to use SQL*Plus with Easy Connection Identifier format in command line. I solved this problem as follows.
The SQL*Plus® User's Guide and Reference gives an example:
sqlplus hr@\"sales-server:1521/sales.us.acme.com\"
Pay attention to two important points:
I found these good questions to detect service name via existing connection: 1, 2. Try this query for example:
SELECT value FROM V$SYSTEM_PARAMETER WHERE UPPER(name) = 'SERVICE_NAMES'

I want change default directory dumpfile.
You could create a new directory and give it required privileges, for example:
SQL> CREATE DIRECTORY dmpdir AS '/opt/oracle';
Directory created.
SQL> GRANT read, write ON DIRECTORY dmpdir TO scott;
Grant succeeded.
To use the newly created directory, you could just add it as a parameter:
DIRECTORY=dmpdir
Oracle introduced a default directory from 10g R2, called DATA_PUMP_DIR, that can be used. To check the location, you could look into dba_directories:
SQL> select DIRECTORY_NAME, DIRECTORY_PATH from dba_directories where DIRECTORY_NAME = 'DATA_PUMP_DIR';
DIRECTORY_NAME DIRECTORY_PATH
-------------------- --------------------------------------------------
DATA_PUMP_DIR C:\app\Lalit/admin/orcl/dpdump/

This message means the 'emulator-x86' or 'emulator64-x86' program is missing from $SDK/tools/, or cannot be found for some reason.
First of all, are you sure you have a valid download / install of the SDK?
I encounter similar problem when installing oracle 11gR2 on Windows 2012 server. the problem is solved when I run cmd.exe as Admistrator privilege and run "lsnrctl start LISTENER".
For me the error was:
Error: unexpected input in "?"
and the fix was opening the script in a hex editor and removing the first 3 characters from the file. The file was starting with an UTF-8 BOM and it seems that Rscript can't read that.
EDIT: OP requested an example. Here it goes.

The database registers its service name(s) with the listener when it starts up. If it is unable to do so then it tries again periodically - so if the listener starts after the database then there can be a delay before the service is recognised.
If the database isn't running, though, nothing will have registered the service, so you shouldn't expect the listener to know about it - lsnrctl status
or lsnrctl services
won't report a service that isn't registered yet.
You can start the database up without the listener; from the Oracle account and with your ORACLE_HOME
, ORACLE_SID
and PATH
set you can do:
sqlplus /nolog
Then from the SQL*Plus prompt:
connect / as sysdba
startup
Or through the Grid infrastructure, from the grid account, use the srvctl start database
command:
srvctl start database -d db_unique_name [-o start_options] [-n node_name]
You might want to look at whether the database is set to auto-start in your oratab
file, and depending on what you're using whether it should have started automatically. If you're expecting it to be running and it isn't, or you try to start it and it won't come up, then that's a whole different scenario - you'd need to look at the error messages, alert log, possibly trace files etc. to see exactly why it won't start, and if you can't figure it out, maybe ask on Database Adminsitrators rather than on Stack Overflow.
If the database can't see +DATA
then ASM may not be running; you can see how to start that here; or using srvctl start asm
. As the documentation says, make sure you do that from the grid home, not the database home.
According to Github API two empty lines are a new paragraph (same as here in stackoverflow)

justify-content
only has an effect if there's space left over after your flex items have flexed to absorb the free space. In most/many cases, there won't be any free space left, and indeed justify-content
will do nothing.
Some examples where it would have an effect:
if your flex items are all inflexible (flex: none
or flex: 0 0 auto
), and smaller than the container.
if your flex items are flexible, BUT can't grow to absorb all the free space, due to a max-width
on each of the flexible items.
In both of those cases, justify-content
would be in charge of distributing the excess space.
In your example, though, you have flex items that have flex: 1
or flex: 6
with no max-width
limitation. Your flexible items will grow to absorb all of the free space, and there will be no space left for justify-content
to do anything with.
I came hear looking for this answer but also wanted to pipe it to another command. The given answer is correct but if anyone wants to pipe it, you need to pipe it before the multi-line string like this
echo | tee /tmp/pipetest << EndOfMessage
This is line 1.
This is line 2.
Line 3.
EndOfMessage
This will allow you to have a multi line string but also put it in the stdin of a subsequent command.
In MySQL, certain words like SELECT
, INSERT
, DELETE
etc. are reserved words. Since they have a special meaning, MySQL treats it as a syntax error whenever you use them as a table name, column name, or other kind of identifier - unless you surround the identifier with backticks.
As noted in the official docs, in section 10.2 Schema Object Names (emphasis added):
Certain objects within MySQL, including database, table, index, column, alias, view, stored procedure, partition, tablespace, and other object names are known as identifiers.
...
If an identifier contains special characters or is a reserved word, you must quote it whenever you refer to it.
...
The identifier quote character is the backtick ("
`
"):
A complete list of keywords and reserved words can be found in section 10.3 Keywords and Reserved Words. In that page, words followed by "(R)" are reserved words. Some reserved words are listed below, including many that tend to cause this issue.
You have two options.
The simplest solution is simply to avoid using reserved words as identifiers. You can probably find another reasonable name for your column that is not a reserved word.
Doing this has a couple of advantages:
It eliminates the possibility that you or another developer using your database will accidentally write a syntax error due to forgetting - or not knowing - that a particular identifier is a reserved word. There are many reserved words in MySQL and most developers are unlikely to know all of them. By not using these words in the first place, you avoid leaving traps for yourself or future developers.
The means of quoting identifiers differs between SQL dialects. While MySQL uses backticks for quoting identifiers by default, ANSI-compliant SQL (and indeed MySQL in ANSI SQL mode, as noted here) uses double quotes for quoting identifiers. As such, queries that quote identifiers with backticks are less easily portable to other SQL dialects.
Purely for the sake of reducing the risk of future mistakes, this is usually a wiser course of action than backtick-quoting the identifier.
If renaming the table or column isn't possible, wrap the offending identifier in backticks (`
) as described in the earlier quote from 10.2 Schema Object Names.
An example to demonstrate the usage (taken from 10.3 Keywords and Reserved Words):
mysql> CREATE TABLE interval (begin INT, end INT); ERROR 1064 (42000): You have an error in your SQL syntax. near 'interval (begin INT, end INT)'
mysql> CREATE TABLE `interval` (begin INT, end INT); Query OK, 0 rows affected (0.01 sec)
Similarly, the query from the question can be fixed by wrapping the keyword key
in backticks, as shown below:
INSERT INTO user_details (username, location, `key`)
VALUES ('Tim', 'Florida', 42)"; ^ ^
Your port 80 is being used by the system.
And from "Overview>>CPU" just Right click on that process and click "End Process Tree". If that process is system that might be a critical issue.
For windows
Check python path in system variable. npm plugins need node-gyp to be installed.
open command prompt with admin rights, and run following command.
npm install --global --production windows-build-tools
npm install --global node-gyp
dmidecode -t 17 | grep Size:
Adding all above values displayed after "Size: " will give exact total physical size of all RAM sticks in server.
Map
does not supports duplicate keys. you can use collection as value against same key.
Associates the specified value with the specified key in this map (optional operation). If the map previously contained a mapping for the key, the old value is replaced by the specified value.
you can use any kind of List
or Set
implementation according to your requirement.
If your values might be also duplicate you can go with ArrayList
or LinkedList
, in case values are unique you can use HashSet
or TreeSet
etc.
Also In google guava collection library Multimap
is available, it is a collection that maps keys to values, similar to Map, but in which each key may be associated with multiple values. You can visualize the contents of a multimap either as a map from keys to nonempty collections of values:
a ? 1, 2
b ? 3
Example -
ListMultimap<String, String> multimap = ArrayListMultimap.create();
multimap.put("a", "1");
multimap.put("a", "2");
multimap.put("c", "3");

When we convert PHP array into JS array then we get all values in string. For example:
var ars= '<?php echo json_encode($abc); ?>';
The issue in above method is when we try to get the first element of ars[0]
then it gives us bracket where as in we need first element as compare to bracket so the better way to this is
var packing_slip_orders = JSON.parse('<?php echo json_encode($packing_slip_orders); ?>');
You should use json_parse
after json_encode
to get the accurate array result.
Using the "point" leads to the creation of a folder named "point" (on Ubuntu 16).

I had the similar issue. its resolved for me with a simple command.
lsnrctl start
The Network Adapter exception is caused because:
lsnrctl
utility.Try to start the listener using the command prompt:
cmd
in the search field, and when cmd
shows up in the list of options, right click it and select ‘Run as Administrator’.lsnrctl start
without the quotes and press Enter.Exit
and press Enter.Hope it helps.
your line raising the error is here:
comment = Comment.objects.get(pk=comment_id)
you try to access a non-existing comment.
from django.shortcuts import get_object_or_404
comment = get_object_or_404(Comment, pk=comment_id)
Instead of having an error on your server, your user will get a 404 meaning that he tries to access a non existing resource.
Ok up to here I suppose you are aware of this.
Some users (and I'm part of them) let tabs running for long time, if users are authorized to delete data, it may happens. A 404 error may be a better error to handle a deleted resource error than sending an email to the admin.
Other users go to addresses from their history, (same if data have been deleted since it may happens).
To get a user Input :
set /p pathName=Enter The Value:%=%
@echo %pathName%
p.s. this is also valid :
set /p pathName=Enter The Value:
Little late to the game but i found a way to fix this for me that i had not seen anywhere else. Select your connection from Connection Managers. On the right you should see properties. Check to see if there are any expressions there if not add one. In your package explorer add a variable called connection to sql or whatever. Set the variable as a string and set the value as your connection string and include the User Id and password. Back to the connection manager properties and expression. From the drop down select ConnectionString and set the second box as the name of your variable. It should look like this
I could not for the life of me find another solution but this worked!
Mainly I use the following command under the cmd

Install URL rewriting:
UPDATE - this is now available here (and works with IIS 7-10):

One more way to do it.
Add commit on the top of temporary commit and then do:
git rebase -i
To merge two commits into one (command will open text file with explicit instructions, edit it).
If anyone like me is searching to read only a specific line, example only line 18 here is the code:
filename = "C:\log.log"
Set fso = CreateObject("Scripting.FileSystemObject")
Set f = fso.OpenTextFile(filename)
For i = 1 to 17
f.ReadLine
Next
strLine = f.ReadLine
Wscript.Echo strLine
f.Close
See String Formatting Operations:
%d
is the format code for an integer. %f
is the format code for a float.
%s
prints the str()
of an object (What you see when you print(object)
).
%r
prints the repr()
of an object (What you see when you print(repr(object))
.
For a float %s, %r and %f all display the same value, but that isn't the case for all objects. The other fields of a format specifier work differently as well:
>>> print('%10.2s' % 1.123) # print as string, truncate to 2 characters in a 10-place field.
1.
>>> print('%10.2f' % 1.123) # print as float, round to 2 decimal places in a 10-place field.

Python is neither pass-by-value nor pass-by-reference. It's more of "object references are passed by value" as described here:
Here's why it's not pass-by-value. Because
def append(list):
list.append(1)
list = [0]
reassign(list)
append(list)
returns [0,1] showing that some kind of reference was clearly passed as pass-by-value does not allow a function to alter the parent scope at all.
Looks like pass-by-reference then, hu? Nope.
Here's why it's not pass-by-reference. Because
def reassign(list):
list = [0, 1]
list = [0]
reassign(list)
print list
returns [0] showing that the original reference was destroyed when list was reassigned. pass-by-reference would have returned [0,1].
For more information look here:
If you want your function to not manipulate outside scope, you need to make a copy of the input parameters that creates a new object.
from copy import copy
def append(list):
list2 = copy(list)
list2.append(1)
print list2
list = [0]
append(list)
print list
If you already haven't done it, try adding "SDK Path\Include"
to:
Project ? Preferences ? C/C++ ? General ? Additional Include Directories
And add "SDK Path\Lib"
to:
Project ? Preferences ? Linker ? General ? Additional Library Directories
Also, try to change "Windows.h"
to <windows.h>
If won't help, check the physical existence of the file, it should be in "\VC\PlatformSDK\Include" folder in your Visual Studio install directory.

Heroku sometimes has a problem with database load balancing.
André Laszlo
, markshiz
and me all reported dealing with that in comments on the question.
To save you the support call, here's the response I got from Heroku Support for a similar issue:
Hello,
One of the limitations of the hobby tier databases is unannounced maintenance. Many hobby databases run on a single shared server, and we will occasionally need to restart that server for hardware maintenance purposes, or migrate databases to another server for load balancing. When that happens, you'll see an error in your logs or have problems connecting. If the server is restarting, it might take 15 minutes or more for the database to come back online.
Most apps that maintain a connection pool (like ActiveRecord in Rails) can just open a new connection to the database. However, in some cases an app won't be able to reconnect. If that happens, you can heroku restart your app to bring it back online.
This is one of the reasons we recommend against running hobby databases for critical production applications. Standard and Premium databases include notifications for downtime events, and are much more performant and stable in general. You can use pg:copy to migrate to a standard or premium plan.
If this continues, you can try provisioning a new database (on a different server) with heroku addons:add, then use pg:copy to move the data. Keep in mind that hobby tier rules apply to the $9 basic plan as well as the free database.
Thanks, Bradley
The reason is actually very simple. When using a query parameter you can take in characters such as "/" and your client does not need to html encode them. There are other reasons but that is a simple example. As for when to use a path variable. I would say whenever you are dealing with ids or if the path variable is a direction for a query.
I suspect that result1 has some characters at the end of it that you can't see in the debugger that follow the closing }
character. What's the length of result1
versus result2
? I'll note that result2
as you've quoted it has 169 characters.
GSON throws that particular error when there's extra characters after the end of the object that aren't whitespace, and it defines whitespace very narrowly (as the JSON spec does) - only \t
, \n
, \r
, and space count as whitespace. In particular, note that trailing NUL (\0
) characters do not count as whitespace and will cause this error.
If you can't easily figure out what's causing the extra characters at the end and eliminate them, another option is to tell GSON to parse in lenient mode:
Gson gson = new Gson();
JsonReader reader = new JsonReader(new StringReader(result1));
reader.setLenient(true);
Userinfo userinfo1 = gson.fromJson(reader, Userinfo.class);
I had a similar problem getting scrollTop to work after reload of div content. The content scrolled to top each time the procedure below was run. I found that a little delay before setting the new scrolltop solved the issue.
This is cut from wdCalendar where I modified this procedure:
function BuildDaysAndWeekView(startday, l, events, config)
....
var scrollpos = $("#dvtec").scrollTop();
gridcontainer.html(html.join(""));
setTimeout(function() {
$("#dvtec").scrollTop(scrollpos);
}, 25);
....
Without the delay, it simply did not work.

Or alternatively
Reserved.objects.filter(client=client_id).latest('-check_in')
Here is the documentations for earliest()

This webpage have an explanation and a solution.
The solution is:
To fix this problem the behavior of the kernel has to be changed, so it will no longer overcommit the memory for application requests. Finally I have included those mentioned values into the /etc/sysctl.conf file, so they get automatically applied on start-up:
vm.overcommit_memory = 2
vm.overcommit_ratio = 80
Working in bash 4 or higher version:

echo $@; #"p1" "p2" "p3" "p4" "p5"
echo ${@: 0}; #"bash" "p1" "p2" "p3" "p4" "p5"
echo ${@: 1}; #"p1" "p2" "p3" "p4" "p5"
echo ${@: 2}; #"p2" "p3" "p4" "p5"
echo ${@: 2:1}; #"p2"
echo ${@: 2:2}; #"p2" "p3"
echo ${@: -2}; #"p4" "p5"
echo ${@: -2:1}; #"p4"
Notice the space between ':' and '-', otherwise it means different:
${var:-word} If var is null or unset,
word is substituted for var. The value of var does not change.${var:+word} If var is set,
word is substituted for var. The value of var does not change.
Which is described in:Unix / Linux - Shell Substitution

I can see this is an old thread, just thought I'd give my 2cents. Not sure if it would fit every scenario, but this is the method I've been successfully using for a number of years:
session_start();
if($_POST == $_SESSION['oldPOST']) $_POST = array(); else $_SESSION['oldPOST'] = $_POST;
Doesn't really delete POST-ed values from the browser, but as far as your php script below these lines is concerned, there is no more POST variables.
Enable Mixed authentication mode while installing MSSQL server. Also provide password for sa user.
Practically speaking, if the keys were of type NaN, the browser will not change the order.
The following script will output "One", "Two", "Three":
var foo={"3":"Three", "1":"One", "2":"Two"};
for(bar in foo) {
alert(foo[bar]);
}
Whereas the following script will output "Three", "One", "Two":
var foo={"@3":"Three", "@1":"One", "@2":"Two"};
for(bar in foo) {
alert(foo[bar]);
}
I had a similar error..This might be due to two reasons. a) If you have used variables, re-evaluate the expressions in which variables are used and make sure the expression is evaluated without errors. b) If you are deleting the excel sheet and creating excel sheet on the fly in your package.
To reference MySQL 8.0.15 + , the password() function is not available. Use the command below.
Kindly use
UPDATE mysql.user SET authentication_string='password' WHERE User='root';

Step 1 – Check the DB listener status
lsnrctl status
Notice that the listener you want (in our case “orcl”) is not showing.
Step 2 – Login via sqlplus
sqlplus sys/oracle as sysdba
Sqlplus gave us this error message:
Writing audit records to Windows Event Log failed
Step 3 – Go into the Windows Event Viewer (eventvwr.exe)
Under “Windows Logs”, right click on Application and select “Clear Log”. Do the same for System.
It may also be wise to right click on Application and select Properties. Then, under “Log Size” select the following option under “When maximum log size is reached”: “Overwrite events as needed”. This should prevent the log from maxing out and causing the DB not to start.
In Windows Vista and higher, you can execute the following command to clear the Application log:
wevtutil cl Application
Step 4 – Login via sqlplus
sqlplus sys/oracle as sysdba
You should now be able to login with no error messages.
Step 5 - Check the DB listener status
lsnrctl status
You should now see your listener running.
Step 6 – Start UCM
UCM should now start up.
For a more in-depth answer to this question you can read my full blog post.
Try to configure the setting of your projects, it is usually due to x86/x64 architecture problems:
Go and set your choice as shown:
I am willing to bet some of my reputation that there is no such thing.
Partially because if you are worried about cross-platform SQL compatibility, your best bet in turn is to abstract your database code with some API or ORM tool that handles these things for you, and is well supported, so will deal with newer database versions as they come out.
Exact kind of API available to you will be dependent on your programming language/platform. For example, PHP has Pear:DB and others, I personally have found quite nice Python's ORM features implemented in Django framework. I presume there should be some of these things available on other platforms as well.
I was using single quotes around the password parameter when I got the error
/p:password='my secret'
bad
and changed it to use double quotes to resolve the issue.
/p:password="my secret"
good
Likely the same would apply to any parameter that needs quotes for values that contain a space.
Header header = new Header();
Byte[] headerBytes = new Byte[Marshal.SizeOf(header)];
Marshal.Copy((IntPtr)(&header), headerBytes, 0, headerBytes.Length);
This should do the trick quickly, right?
I Changed Sid Value to orcl
, it works fine and connection established
If you want to build your solution for x86 and x64, your solution must be configured for both platforms. Actually you just have an Any CPU configuration.
To check the available configuration for a given project, open the project file (*.csproj
for example) and look for a PropertyGroup
with the right Condition
.
If you want to build in Release
mode for x86
, you must have something like this in your project file:
<PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Release|x86' ">
...
</PropertyGroup>
(source: microsoft.com)
(source: msdn.com)
(source: msdn.com)
How to create and edit the configuration (on MSDN)

If you are interested in portability between different SQL servers you should use ANSI SQL queries. String escaping in ANSI SQL is done by using double quotes ("). Unfortunately, this escaping method is not portable to MySQL, unless it is set in ANSI compatibility mode.
Personally, I always start my MySQL server with the --sql-mode='ANSI' argument since this allows for both methods for escaping. If you are writing queries that are going to be executed in a MySQL server that was not setup / is controlled by you, here is what you can do:
Enclose them in the following MySQL specific queries:
SET @OLD_SQL_MODE=@@SQL_MODE;
SET SESSION SQL_MODE='ANSI';
-- ANSI SQL queries
SET SESSION SQL_MODE=@OLD_SQL_MODE;
This way the only MySQL specific queries are at the beginning and the end of your .sql script. If you what to ship them for a different server just remove these 3 queries and you're all set. Even more conveniently you could create a script named: script_mysql.sql that would contain the above mode setting queries, source a script_ansi.sql script and reset the mode.
The argument to split is a regular expression. The period is a regular expression metacharacter that matches anything, thus every character in line
is considered to be a split character, and is thrown away, and all of the empty strings between them are thrown away (because they're empty strings). The result is that you have nothing left.
If you escape the period (by adding an escaped backslash before it), then you can match literal periods. (line.split("\\.")

If your testing requires pulling quasi-real credit reports from the bureaus, the inactive SSNs of other answers won't work and you'll need designated test numbers.
I found this site Which appears to contain test social security numbers with associated test names and credit card numbers.
Transunion has a test environment you can link and send data to, including associated dummy credit reports. Sending a SSN to them with certain numbers in certain positions will automatically route the inquiry to their test environment Other credit bureaus will have similar systems in place.
The story of %2F
vs /
was that, according to the initial W3C recommendations, slashes «must imply a hierarchical structure»:
The slash ("/", ASCII 2F hex) character is reserved for the delimiting of substrings whose relationship is hierarchical. This enables partial forms of the URI.
Example 2
The URIs
http://www.w3.org/albert/bertram/marie-claude
and
http://www.w3.org/albert/bertram%2Fmarie-claude
are NOT identical, as in the second case the encoded slash does not have hierarchical significance.

From a quick search, Oracle appears to use double quotes ("
, eg "table"
) and apparently requires the correct case—whereas, for anyone interested, MySQL defaults to using backticks (`) except when set to use double quotes for compatibility.
Sometimes it can get really complicated. The easy way is to "refresh" the button view!
//Do stuff to your button here. For example:
[mybutton setEnabled:YES];
//Refresh it to new state.
[mybutton setNeedsDisplay];
Use the reindent.py
script that you find in the Tools/scripts/
directory of your Python installation:
Change Python (.py) files to use 4-space indents and no hard tab characters. Also trim excess spaces and tabs from ends of lines, and remove empty lines at the end of files. Also ensure the last line ends with a newline.
Have a look at that script for detailed usage instructions.
This is Oracle bug, memory leak in shared_pool, most likely db managing lots of partitions. Solution: In my opinion patch not exists, check with oracle support. You can try with subpools or en(de)able AMM ...
Well, I can think of a CSS hack that will resolve this issue.
You could add the following line in your CSS file:
* html .blog_list div.postbody img { width:75px; height: SpecifyHeightHere; }
The above code will only be seen by IE6. The aspect ratio won't be perfect, but you could make it look somewhat normal. If you really wanted to make it perfect, you would need to write some javascript that would read the original picture width, and set the ratio accordingly to specify a height.
For Oracle 11g, I was able to change the column attribute as follows:
ALTER TABLE tablename MODIFY columnname datatype NOT NULL;
Otherwise abatichev's answer seemed good. You can't repeat the alter - it complains (at least in SQL Developer) that the column is already not null.
One way of reducing the heap sice of a system with limited resources may be to play around with the -XX:MaxHeapFreeRatio variable. This is usually set to 70, and is the maximum percentage of the heap that is free before the GC shrinks it. Setting it to a lower value, and you will see in eg the jvisualvm profiler that a smaller heap sice is usually used for your program.
EDIT: To set small values for -XX:MaxHeapFreeRatio you must also set -XX:MinHeapFreeRatio Eg
java -XX:MinHeapFreeRatio=10 -XX:MaxHeapFreeRatio=25 HelloWorld
EDIT2: Added an example for a real application that starts and does the same task, one with default parameters and one with 10 and 25 as parameters. I didn't notice any real speed difference, although java in theory should use more time to increase the heap in the latter example.
At the end, max heap is 905, used heap is 378
At the end, max heap is 722, used heap is 378
This actually have some inpact, as our application runs on a remote desktop server, and many users may run it at once.

Some more detail for completeness in case it helps someone...
Note that the most common reason for this exception these days is attempting to load a 32 bit-specific (/platform:x86
) DLL into a process that is 64 bit or vice versa (viz. load a 64 bit-specific (/platform:x64
) DLL into a process that is 32 bit). If your platform
is non-specific (/platform:AnyCpu
), this won't arise (assuming no referenced dependencies are of the wrong bitness).
In other words, running:
%windir%\Microsoft.NET\Framework\v2.0.50727\installutil.exe
or:
%windir%\Microsoft.NET\Framework64\v2.0.50727\installutil.exe
will not work (substitute in other framework versions: v1.1.4322
(32-bit only, so this issue doesn't arise) and v4.0.30319
as desired in the above).
Obviously, as covered in the other answer, one will also need the .NET version number of the installutil
you are running to be >= (preferably =) that of the EXE/DLL file you are running the installer of.
Finally, note that in Visual Studio 2010, the tooling will default to generating x86 binaries (rather than Any CPU as previously).
Complete details of System.BadImageFormatException (saying the only cause is mismatched bittedness is really a gross oversimplification!).
Another reason for a BadImageFormatException
under an x64 installer is that in Visual Studio 2010, the default .vdproj
Install Project type generates a 32-bit InstallUtilLib
shim, even on an x64 system (Search for "64-bit managed custom actions throw a System.BadImageFormatException exception" on the page).
Here's an extension method. Not sure where I found it.
public static class StringExtensions
{
public static string Replace(this string originalString, string oldValue, string newValue, StringComparison comparisonType)
{
int startIndex = 0;
while (true)
{
startIndex = originalString.IndexOf(oldValue, startIndex, comparisonType);
if (startIndex == -1)
break;
originalString = originalString.Substring(0, startIndex) + newValue + originalString.Substring(startIndex + oldValue.Length);
startIndex += newValue.Length;
}
return originalString;
}
}
DOS/Windows standard "newline" is CRLF (= \r\n) and not LFCR (\n\r). If we put the latter, it's likely to produce some unexpected (well, in fact, kind of expected! :D) behaviors.
Nowadays almost all (well written) programs accept the UNIX standard LF (\n) for newline code, even mail sender daemons (RFC sets CRLF as newline for headers and message body).
It depends on the platform and compiler that you're using. Some compilers store directly in the code segment. Static variables are always only accessible to the current translation unit and the names are not exported thus the reason name collisions never occur.
You should always use "throw;" to rethrow the exceptions in .NET,
Refer this, http://weblogs.asp.net/bhouse/archive/2004/11/30/272297.aspx
Basically MSIL (CIL) has two instructions - "throw" and "rethrow":
Basically I can see the reason why "throw ex" overrides the stack trace.
You cannot add a column with a default value in Hive. You have the right syntax for adding the column ALTER TABLE test1 ADD COLUMNS (access_count1 int);
, you just need to get rid of default sum(max_count)
. No changes to that files backing your table will happen as a result of adding the column. Hive handles the "missing" data by interpreting NULL
as the value for every cell in that column.
So now your have the problem of needing to populate the column. Unfortunately in Hive you essentially need to rewrite the whole table, this time with the column populated. It may be easier to rerun your original query with the new column. Or you could add the column to the table you have now, then select all of its columns plus value for the new column.
You also have the option to always COALESCE
the column to your desired default and leave it NULL
for now. This option fails when you want NULL
to have a meaning distinct from your desired default. It also requires you to depend on always remembering to COALESCE
.
If you are very confident in your abilities to deal with the files backing Hive, you could also directly alter them to add your default. In general I would recommend against this because most of the time it will be slower and more dangerous. There might be some case where it makes sense though, so I've included this option for completeness.
Just like you do for getting something from the CNode
you also need to do for the ANode
XmlNodeList xnList = xml.SelectNodes("/Element[@*]");
foreach (XmlNode xn in xnList)
{
XmlNode anode = xn.SelectSingleNode("ANode");
if (anode!= null)
{
string id = anode["ID"].InnerText;
string date = anode["Date"].InnerText;
XmlNodeList CNodes = xn.SelectNodes("ANode/BNode/CNode");
foreach (XmlNode node in CNodes)
{
XmlNode example = node.SelectSingleNode("Example");
if (example != null)
{
string na = example["Name"].InnerText;
string no = example["NO"].InnerText;
}
}
}
}
SELECT CONCAT(LOWER(LAST_NAME), UPPER(LAST_NAME)
INITCAP(LAST_NAME), HIRE DATE AS ‘up_low_init_hdate’)

A URL of the form https://github.com/<owner>/<project>/commit/<hash>
will show you the changes introduced in that commit. For example here's a recent bugfix I made to one of my projects on GitHub:
https://github.com/jerith666/git-graph/commit/35e32b6a00dec02ae7d7c45c6b7106779a124685
You can also shorten the hash to any unique prefix, like so:
https://github.com/jerith666/git-graph/commit/35e32b
I know you just asked about GitHub, but for completeness: If you have the repository checked out, from the command line, you can achieve basically the same thing with either of these commands (unique prefixes work here too):
git show 35e32b6a00dec02ae7d7c45c6b7106779a124685
git log -p -1 35e32b6a00dec02ae7d7c45c6b7106779a124685
Note: If you shorten the commit hash too far, the command line gives you a helpful disambiguation message, but GitHub will just return a 404.
I think you are saying that a container
vs container-fluid
is the difference between responsive and non-responsive to the grid. This is not true...what is saying is that the width is not fixed...its full width!
This is hard to explain so lets look at the examples
Example one
container-fluid
:
So you see how the container takes up the whole screen...that's a container-fluid
.
Now lets look at the other just a normal container
and watch the edges of the preview
Example two
container
Now do you see the white space in the example? That's because its a fixed width container
! It might make more sense to open both examples up in two different tabs and switch back and forth.
EDIT
Better yet here is an example with both containers at once! Now you can really tell the difference!
I hope this helped clarify a little bit!
Update (2017): The following two libraries have now become the most common drop-down libraries used with Javascript. While they are jQuery-native, they have been customized to work with everything from AngularJS 1.x to having custom CSS for Bootstrap. (Chosen JS, the original answer here, seems to have dropped to #3 in popularity.)
Obligatory screenshots below.
Original answer (2012): I think that the Chosen library might also be useful. Its available in jQuery, Prototype and MooTools versions.
Attached is a screenshot of how the multi-select functionality looks in Chosen.
The question was :
Is there a fast way of getting all COLUMN NAMES from all tables in MySQL, without having to list all the tables?
SQL to get all information for each column
select * from information_schema.columns
where table_schema = 'your_db'
order by table_name,ordinal_position
SQL to get all COLUMN NAMES
select COLUMN_NAME from information_schema.columns
where table_schema = 'your_db'
order by table_name,ordinal_position
In file /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.1.sdk/SDKSettings.plist

To use the Combobox
in the way you intend, you could pass in an object to the cmbTripName.Items.Add
method.
That object should have FleetID
and FleetName
properties:
while (drd.Read())
{
cmbTripName.Items.Add(new Fleet(drd["FleetID"].ToString(), drd["FleetName"].ToString()));
}
cmbTripName.ValueMember = "FleetId";
cmbTripName.DisplayMember = "FleetName";
The Fleet
Class:
class Fleet
{
public Fleet(string fleetId, string fleetName)
{
FleetId = fleetId;
FleetName = fleetName
}
public string FleetId {get;set;}
public string FleetName {get;set;}
}
Or, You could probably do away with the need for a Fleet
class completely by using an anonymous type...
while (drd.Read())
{
cmbTripName.Items.Add(new {FleetId = drd["FleetID"].ToString(), FleetName = drd["FleetName"].ToString()});
}
cmbTripName.ValueMember = "FleetId";
cmbTripName.DisplayMember = "FleetName";
It can also be done with a positive assertion of removal, like this:
textContent = textContent.replace(/[\u{0080}-\u{FFFF}]/gu,"");
This uses unicode. In Javascript, when expressing unicode for a regular expression, the characters are specified with the escape sequence \u{xxxx}
but also the flag 'u'
must present; note the regex has flags 'gu'
.
I called this a "positive assertion of removal" in the sense that a "positive" assertion expresses which characters to remove, while a "negative" assertion expresses which letters to not remove. In many contexts, the negative assertion, as stated in the prior answers, might be more suggestive to the reader. The circumflex "^
" says "not" and the range \x00-\x7F
says "ascii," so the two together say "not ascii."
textContent = textContent.replace(/[^\x00-\x7F]/g,"");
That's a great solution for English language speakers who only care about the English language, and its also a fine answer for the original question. But in a more general context, one cannot always accept the cultural bias of assuming "all non-ascii is bad." For contexts where non-ascii is used, but occasionally needs to be stripped out, the positive assertion of Unicode is a better fit.
A good indication that zero-width, non printing characters are embedded in a string is when the string's "length" property is positive (nonzero), but looks like (i.e. prints as) an empty string. For example, I had this showing up in the Chrome debugger, for a variable named "textContent":
> textContent
""
> textContent.length
7
This prompted me to want to see what was in that string.
> encodeURI(textContent)
"%E2%80%8B%E2%80%8B%E2%80%8B%E2%80%8B%E2%80%8B%E2%80%8B%E2%80%8B"
This sequence of bytes seems to be in the family of some Unicode characters that get inserted by word processors into documents, and then find their way into data fields. Most commonly, these symbols occur at the end of a document. The zero-width-space "%E2%80%8B"
might be inserted by CK-Editor (CKEditor).
encodeURI() UTF-8 Unicode html Meaning
----------- -------- ------- ------- -------------------
"%E2%80%8B" EC 80 8B U 200B ​ zero-width-space
"%E2%80%8E" EC 80 8E U 200E ‎ left-to-right-mark
"%E2%80%8F" EC 80 8F U 200F ‏ right-to-left-mark
Some references on those:
http://www.fileformat.info/info/unicode/char/200B/index.htm
https://en.wikipedia.org/wiki/Left-to-right_mark
Note that although the encoding of the embedded character is UTF-8, the encoding in the regular expression is not. Although the character is embedded in the string as three bytes (in my case) of UTF-8, the instructions in the regular expression must use the two-byte Unicode. In fact, UTF-8 can be up to four bytes long; it is less compact than Unicode because it uses the high bit (or bits) to escape the standard ascii encoding. That's explained here:
You can use math.ceil()
to round up, and then multiply by 10
import math
def roundup(x):
return int(math.ceil(x / 10.0)) * 10
To use just do
>>roundup(45)
50
When I used Apache HTTP Client 4.3, I was using the Pooled or Basic Connection Managers to the HTTP Client. I noticed, from using java SSL debugging, that these classes loaded the cacerts trust store and not the one I had specified programmatically.
PoolingHttpClientConnectionManager cm = new PoolingHttpClientConnectionManager();
BasicHttpClientConnectionManager cm = new BasicHttpClientConnectionManager();
builder.setConnectionManager( cm );
I wanted to use them but ended up removing them and creating an HTTP Client without them. Note that builder is an HttpClientBuilder.
I confirmed when running my program with the Java SSL debug flags, and stopped in the debugger. I used -Djavax.net.debug=ssl as a VM argument. I stopped my code in the debugger and when either of the above *ClientConnectionManager were constructed, the cacerts file would be loaded.
First of all you missed ScriptService attribute to add in webservice.
[ScriptService]
After then try following method to call webservice via JSON.
var webAddr = "http://Domain/VBRService.asmx/callJson"; var httpWebRequest = (HttpWebRequest)WebRequest.Create(webAddr); httpWebRequest.ContentType = "application/json; charset=utf-8"; httpWebRequest.Method = "POST"; using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream())) { string json = "{\"x\":\"true\"}"; streamWriter.Write(json); streamWriter.Flush(); } var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse(); using (var streamReader = new StreamReader(httpResponse.GetResponseStream())) { var result = streamReader.ReadToEnd(); return result; }
An alternative approach:
If
then
Example:
Instead of
# This comment
# is too long
use
Description: >
This comment
is too long
or
Comment: >
This comment is also too long
and newlines survive from parsing!
More advantages:
You're looking for the zip builtin function. From the docs:
>>> x = [1, 2, 3]
>>> y = [4, 5, 6]
>>> zipped = zip(x, y)
>>> zipped
[(1, 4), (2, 5), (3, 6)]
For jQuery 1.9+ as Dunstkreis mentioned .data('events') was removed. But you can use another hack (it is not recommended to use undocumented possibilities) $._data($(this).get(0), 'events') instead and solution provided by anurag will look like:
$.fn.bindFirst = function(name, fn) {
this.bind(name, fn);
var handlers = $._data($(this).get(0), 'events')[name.split('.')[0]];
var handler = handlers.pop();
handlers.splice(0, 0, handler);
};
Here are three ways to do it:
Long l = 123L;
Integer correctButComplicated = Integer.valueOf(l.intValue());
Integer withBoxing = l.intValue();
Integer terrible = (int) (long) l;
All three versions generate almost identical byte code:
0 ldc2_w <Long 123> [17]
3 invokestatic java.lang.Long.valueOf(long) : java.lang.Long [19]
6 astore_1 [l]
// first
7 aload_1 [l]
8 invokevirtual java.lang.Long.intValue() : int [25]
11 invokestatic java.lang.Integer.valueOf(int) : java.lang.Integer [29]
14 astore_2 [correctButComplicated]
// second
15 aload_1 [l]
16 invokevirtual java.lang.Long.intValue() : int [25]
19 invokestatic java.lang.Integer.valueOf(int) : java.lang.Integer [29]
22 astore_3 [withBoxing]
// third
23 aload_1 [l]
// here's the difference:
24 invokevirtual java.lang.Long.longValue() : long [34]
27 l2i
28 invokestatic java.lang.Integer.valueOf(int) : java.lang.Integer [29]
31 astore 4 [terrible]
You can build for source following the official OpenCV tutorial. The crucial part is to set the PYTHON3_EXECUTABLE
, PYTHON_LIBRARY
, PYTHON3_PACKAGES_PATH
and PYTHON3_NUMPY_INCLUDE_DIRS
parameters for python3.6
. Here are all the steps:
Clone the repo
git clone https://github.com/opencv/opencv.git
Create build
directory
cd ~/opencv
mkdir build
cd build
Configure
cmake -D CMAKE_BUILD_TYPE=RELEASE \
-D CMAKE_INSTALL_PREFIX=/usr/local .. \
-D PYTHON_INCLUDE_DIR=/usr/include/python3.6 \
-D PYTHON_INCLUDE_DIR2=/usr/include/x86_64-linux-gnu/python3.6m \
-D BUILD_NEW_PYTHON_SUPPORT=ON \
-D BUILD_opencv_python3=ON \
-D HAVE_opencv_python3=ON \
-D INSTALL_PYTHON_EXAMPLES=ON \
-D PYTHON3_EXECUTABLE=/usr/bin/python3.6 \
-D PYTHON_DEFAULT_EXECUTABLE=/usr/bin/python3.6 \
-D PYTHON_LIBRARY=/usr/lib/x86_64-linux-gnu/libpython3.6m.so \
-D PYTHON3_PACKAGES_PATH=/usr/lib/python3/dist-packages .. \
-D PYTHON3_NUMPY_INCLUDE_DIRS=/home/user/.local/lib/python3.6/site-packages/numpy/core/include/
Build
make -j8
Install libraries
sudo make install
Test
python3
import cv2
If you don't get the error "No module named cv2", then the installation was successful.
Note: If you don't know the path to numpy
for the PYTHON3_NUMPY_INCLUDE_DIRS
parameter, you can find it by executing import numpy
and then numpy.__file__
in a python3 shell.
def nested1(num1):
print "nested1 has",num1
def nested2(num2):
print "nested2 has",num2,"and it can reach to",num1
return num1+num2 #num1 referenced for reading here
return nested2
Gives:
In [17]: my_func=nested1(8)
nested1 has 8
In [21]: my_func(5)
nested2 has 5 and it can reach to 8
Out[21]: 13
This is an example of what a closure is and how it can be used.
One caveat: in .NET the linefeed is "\r\n". So if you're loading your text from a file, you might have to use that instead of just "\n"
edit> as samuel pointed out in the comments, "\r\n" is not .NET specific, but is windows specific.
Basically, fs.readFileSync
throws an error when a file is not found. This error is from the Error
prototype and thrown using throw
, hence the only way to catch is with a try / catch
block:
var fileContents;
try {
fileContents = fs.readFileSync('foo.bar');
} catch (err) {
// Here you get the error when the file was not found,
// but you also get any other error
}
Unfortunately you can not detect which error has been thrown just by looking at its prototype chain:
if (err instanceof Error)
is the best you can do, and this will be true for most (if not all) errors. Hence I'd suggest you go with the code
property and check its value:
if (err.code === 'ENOENT') {
console.log('File not found!');
} else {
throw err;
}
This way, you deal only with this specific error and re-throw all other errors.
Alternatively, you can also access the error's message
property to verify the detailed error message, which in this case is:
ENOENT, no such file or directory 'foo.bar'
Hope this helps.
There are two options. The first (and better) one is using the Fetch as Google option in Webmaster Tools that Mike Flynn commented about. Here are detailed instructions:
With the option above, as long as every page can be reached from some link on the initial page or a page that it links to, Google should recrawl the whole thing. If you want to explicitly tell it a list of pages to crawl on the domain, you can follow the directions to submit a sitemap.
Your second (and generally slower) option is, as seanbreeden pointed out, submitting here: http://www.google.com/addurl/
Update 2019:
As DOC says, you can pass data to the handler as next:
// say your selector and click handler looks something like this...
$("some selector").on('click',{param1: "Hello", param2: "World"}, cool_function);
// in your function, just grab the event object and go crazy...
function cool_function(event){
alert(event.data.param1);
alert(event.data.param2);
// access element's id where click occur
alert( event.target.id );
}
In my case, the dump file I restored had these commands.
CREATE SCHEMA employees;
SET search_path = employees, pg_catalog;
I've commented those and restored again. The issue got resolved
You can Implement this also:- setPage(1, n); where, n = any number.
$products = Mage::getResourceModel('catalog/product_collection')
->addAttributeToSelect('*')
->addAttributeToSelect(array('name', 'price', 'small_image'))
->addFieldToFilter('visibility', Mage_Catalog_Model_Product_Visibility::VISIBILITY_BOTH) //visible only catalog & searchable product
->addAttributeToFilter('status', 1) // enabled
->setStoreId($storeId)
->setOrder('created_at', 'desc')
->setPage(1, 6);
Ignore function is used to skip(discard/throw away) characters in the input stream. Ignore file is associated with the file istream. Consider the function below ex: cin.ignore(120,'/n'); the particular function skips the next 120 input character or to skip the characters until a newline character is read.
Something like this:
JSONObject songs= json.getJSONObject("songs");
Iterator x = songs.keys();
JSONArray jsonArray = new JSONArray();
while (x.hasNext()){
String key = (String) x.next();
jsonArray.put(songs.get(key));
}
Typically, a script is a lightweight, quickly constructed, possibly single-use tool. It's usually interpreted, not compiled. Python and bash are examples of languages used to build scripts.
A program is constructed in a compiled language, like C or C++, and usually runs more quickly than a script for that reason. Larger tools are often written as "programs" rather than scripts - smaller tools are more easily developed as scripts, but scripts can get unwieldy as they get larger. Application and system languages (those used to build programs/applications) have tools to make that growth easier to manage.
You can usually view a script in a text editor to see what it does. You can't do that with an executable program - the latter's instructions have been compiled into bytecode or machine language that makes it very difficult for humans to understand, without specialized tools.
Note the number of "oftens" and "usuallys" above - the terms are nebulous, and cross over sometimes.
It's possible, but it requires using dynamic SQL.
I recommend reading The curse and blessings of dynamic SQL before continuing...
DECLARE @theDate varchar(60)
SET @theDate = '''2010-01-01'' AND ''2010-08-31 23:59:59'''
DECLARE @SQL VARCHAR(MAX)
SET @SQL = 'SELECT AdministratorCode,
SUM(Total) as theTotal,
SUM(WOD.Quantity) as theQty,
AVG(Total) as avgTotal,
(SELECT SUM(tblWOD.Amount)
FROM tblWOD
JOIN tblWO on tblWOD.OrderID = tblWO.ID
WHERE tblWO.Approved = ''1''
AND tblWO.AdministratorCode = tblWO.AdministratorCode
AND tblWO.OrderDate BETWEEN '+ @theDate +')'
EXEC(@SQL)
Dynamic SQL is just a SQL statement, composed as a string before being executed. So the usual string concatenation occurs. Dynamic SQL is required whenever you want to do something in SQL syntax that isn't allowed, like:
EXEC sp_executesql
allows you to use bind/preparedstatement parameters so you don't have to concern yourself with escaping single quotes/etc for SQL injection attacks.
Here is what I believe answers the question (Python 3, with type hints):
from datetime import date
def int2date(argdate: int) -> date:
"""
If you have date as an integer, use this method to obtain a datetime.date object.
Parameters
----------
argdate : int
Date as a regular integer value (example: 20160618)
Returns
-------
dateandtime.date
A date object which corresponds to the given value `argdate`.
"""
year = int(argdate / 10000)
month = int((argdate % 10000) / 100)
day = int(argdate % 100)
return date(year, month, day)
print(int2date(20160618))
The code above produces the expected 2016-06-18
.

My comment: help does not include attitude which is a bonus. The attitude post enabled me to search further and find the info.
Have same error from time to time (when I set install location to "prefer external" in manifest). Just clean and rebuild project. Works for me.
Apparently, no.
Here's the options:
is
and as
As you've already found out, this will not work if the two types are the same, here's a sample LINQPad program that demonstrates:
void Main()
{
typeof(Derived).IsSubclassOf(typeof(Base)).Dump();
typeof(Base).IsSubclassOf(typeof(Base)).Dump();
}
public class Base { }
public class Derived : Base { }
Output:
True
False
Which indicates that Derived
is a subclass of Base
, but that Base
is (obviously) not a subclass of itself.
Now, this will answer your particular question, but it will also give you false positives. As Eric Lippert has pointed out in the comments, while the method will indeed return True
for the two above questions, it will also return True
for these, which you probably don't want:
void Main()
{
typeof(Base).IsAssignableFrom(typeof(Derived)).Dump();
typeof(Base).IsAssignableFrom(typeof(Base)).Dump();
typeof(int[]).IsAssignableFrom(typeof(uint[])).Dump();
}
public class Base { }
public class Derived : Base { }
Here you get the following output:
True
True
True
The last True
there would indicate, if the method only answered the question asked, that uint[]
inherits from int[]
or that they're the same type, which clearly is not the case.
So IsAssignableFrom
is not entirely correct either.
is
and as
The "problem" with is
and as
in the context of your question is that they will require you to operate on the objects and write one of the types directly in code, and not work with Type
objects.
In other words, this won't compile:
SubClass is BaseClass
^--+---^
|
+-- need object reference here
nor will this:
typeof(SubClass) is typeof(BaseClass)
^-------+-------^
|
+-- need type name here, not Type object
nor will this:
typeof(SubClass) is BaseClass
^------+-------^
|
+-- this returns a Type object, And "System.Type" does not
inherit from BaseClass
While the above methods might fit your needs, the only correct answer to your question (as I see it) is that you will need an extra check:
typeof(Derived).IsSubclassOf(typeof(Base)) || typeof(Derived) == typeof(Base);
which of course makes more sense in a method:
public bool IsSameOrSubclass(Type potentialBase, Type potentialDescendant)
{
return potentialDescendant.IsSubclassOf(potentialBase)
|| potentialDescendant == potentialBase;
}
Enclose the string in single quote it should work. Try this.
var jsonObj = '{"TeamList" : [{"teamid" : "1","teamname" : "Barcelona"}]}';
var obj = $.parseJSON(jsonObj);
data.frame[row_number, column_number] = new_value
For example, if x
is your data.frame:
x[1, 4] = 5
You can either use the answer from the duplicate link pointed by nvm.
Or you can resolve conflicts by using their changes (but some of your changes might be kept if they don't conflict with remote version):
git pull -s recursive -X theirs
The appropriate way for doing this:
@app.route('/')
def index():
if form.validate_on_submit():
if 'download' in request.form:
pass # do something
elif 'watch' in request.form:
pass # do something else
Put watch
and download
buttons into your template:
<input type="submit" name="download" value="Download">
<input type="submit" name="watch" value="Watch">
Let's say you have three classes: Enemy1, Enemy2, Enemy3. This is how you instantiate them directly:
Enemy1()
Enemy2()
Enemy3()
but this will also work:
x = Enemy1
x()
x = Enemy2
x()
x = Enemy3
x()
Is this what you meant?
WAMP stands for Windows,Apache,Mysql,Php
XAMPP stands for X-os,Apache,Mysql,Php,Perl. (x-os means it can use for any operating system)
It is cross-platform software
It possesses many other essential modules such as phpMyAdmin, OpenSSL, MediaWiki, WordPress, Joomla and more.
it is easy to configure and use.
It is easy to Use. (Changing Configuration)
WAMP is Available for both 64 bit and 32-bit system.
if you are running projects which have specific version requirements WAMP is better choice because you can switch between multiple versions. for example 7x and PHP 5x or Magento2.2.4 won't work on php7.2 but Magento2.3.needs php7.2 or up to work.

The date filter always formats the dates using the local timezone. You'll have to write your own filter, based on the getUTCXxx()
methods of Date
, or on a library like moment.js.
A simple way to look at it is that an id is unique to only one element.
A class is not unique and applied to multiple elements.
For example:
<p class = "content">This is some random <strong id="veryImportant"> stuff!</strong></p>
Content is a class since it'll probably apply to some other tags aswell where as "veryImportant" is only being used once and never again.
you can use this project to play any you tube video , in your android app . Now for other video , or Video id ... you can do this https://gdata.youtube.com/feeds/api/users/eminemvevo/uploads/ where eminemvevo = channel .
after finding , video id , you can put that id in cueVideo("video_id")
src -> com -> examples -> youtubeapidemo -> PlayerViewDemoActivity
@Override
public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer player , boolean wasRestored) {
if (!wasRestored) {
player.cueVideo("wKJ9KzGQq0w");
}
}
And specially for reading that video_id in a better way open this , and it as a xml[1st_file
] file in your desktop after it create a new Xml file in your project
or upload that[1st_file
] saved file in your project , and right_click in it , and open it with xml_editor file , here you will find the video id of the particular video .
Declaring the field as 'final' will ensure that the field is a constant and cannot change. The difference comes in the usage of 'static' keyword.
Declaring a field as static means that it is associated with the type and not with the instances. i.e. only one copy of the field will be present for all the objects and not individual copy for each object. Due to this, the static fields can be accessed through the class name.
As you can see, your requirement that the field should be constant is achieved in both cases (declaring the field as 'final' and as 'static final').
Similar question is private final static attribute vs private final attribute
Hope it helps
Oracle views like ALL_TABLES and ALL_CONSTRAINTS have an owner column, which you can use to restrict your query. There are also variants of these tables beginning with USER instead of ALL, which only list objects which can be accessed by the current user.
One of these views should help to solve your problem. They always worked fine for me for similar problems.
We use object-scan for our data processing and it might be a viable solution here. This is how it could work (also pruning arrays correctly)
// const objectScan = require('object-scan');
const prune = (data) => objectScan(['**'], {
rtn: 'count',
filterFn: ({ isCircular, parent, property }) => {
if (isCircular) {
if (Array.isArray(parent)) {
parent.splice(property, 1);
} else {
delete parent[property];
}
return true;
}
return false;
},
breakFn: ({ isCircular }) => isCircular === true
})(data);
const obj = { a: 'foo', c: [0] };
obj.b = obj;
obj.c.push(obj);
console.log(obj);
// => { a: 'foo', c: [ 0, [Circular] ], b: [Circular] }
console.log(prune(obj)); // returns circular counts
// => 2
console.log(obj);
// => { a: 'foo', c: [ 0 ] }

You don't have any example code but I assume you want to do something like this?
@View({
directives: [NgClass],
styles: [`
.${TodoModel.COMPLETED} {
text-decoration: line-through;
}
.${TodoModel.STARTED} {
color: green;
}
`],
template: `<div>
<span [ng-class]="todo.status" >{{todo.title}}</span>
<button (click)="todo.toggle()" >Toggle status</button>
</div>`
})
You assign ng-class
to a variable which is dynamic (a property of a model called TodoModel
as you can guess).
todo.toggle()
is changing the value of todo.status
and there for the class of the input is changing.
This is an example for class name but actually you could do the same think for css properties.
I hope this is what you meant.
This example is taken for the great egghead tutorial here.
You can run flutter clean
.
But that's most likely a problem with your IDE or similar, as flutter run creates a brand new apk. And hot reload push only modifications.
Try running your app using the command line flutter run
and then press r
or R
for respectively hot-reload and full-reload.
You could also consider using getting the indexes of last elements in each specified dimensions using this as following;
int x = ary.GetUpperBound(0);
int y = ary.GetUpperBound(1);
Keep in mind that this gets the value of index as 0-based.
getopt()
/getopts()
is a good option. Copied from here:
The simple use of "getopt" is shown in this mini-script:
#!/bin/bash
echo "Before getopt"
for i
do
echo $i
done
args=`getopt abc:d $*`
set -- $args
echo "After getopt"
for i
do
echo "-->$i"
done
What we have said is that any of -a, -b, -c or -d will be allowed, but that -c is followed by an argument (the "c:" says that).
If we call this "g" and try it out:
bash-2.05a$ ./g -abc foo
Before getopt
-abc
foo
After getopt
-->-a
-->-b
-->-c
-->foo
-->--
We start with two arguments, and "getopt" breaks apart the options and puts each in its own argument. It also added "--".

As has already been said: figure
will create a new figure for your next plots. While calling figure
you can also configure it. Example:
figHandle = figure('Name', 'Name of Figure', 'OuterPosition',[1, 1, scrsz(3), scrsz(4)]);
The example sets the name for the window and the outer size of it in relation to the used screen.
Here figHandle
is the handle to the resulting figure and can be used later to change appearance and content. Examples:
Dot notation:
figHandle.PaperOrientation = 'portrait';
figHandle.PaperUnits = 'centimeters';
Old Style:
set(figHandle, 'PaperOrientation', 'portrait', 'PaperUnits', 'centimeters');
Using the handle with dot notation or set
, options for printing are configured here.
By keeping the handles for the figures with distinc names you can interact with multiple active figures. To set a existing figure as your active, call figure(figHandle)
. New plots will go there now.
You can easily import your model and run this:
from models import User
# User is the name of table that has a column name
users = User.query.all()
for user in users:
print user.name
The problem here, as explained in other comments, is that the pointer is being dereference without being properly initialized. Operating systems like Linux keep the lowest addresses (eg first 32MB: 0x00_0000 -0x200_0000) out of the virtual address space of a process. This is done because dereferencing zeroed non-initialized pointers is a common mistake, like in this case. So when this type of mistake happens, instead of actually reading a random variable that happens to be at address 0x0 (but not the memory address the pointer would be intended for if initialized properly), the pointer would be reading from a memory address outside of the process's virtual address space. This causes a page fault, which results in a segmentation fault, and a signal is sent to the process to kill it. That's why you are getting the access violation error.
The important thing of table-layout: fixed is that the column widths are determined by the first row of the table.
So
if your table structure is as follow (standard table structure)
<table>
<thead>
<tr>
<th> First column </th>
<th> Second column </th>
<th> Third column </th>
</tr>
</thead>
<tbody>
<tr>
<td> First column </td>
<td> Second column </td>
<td> Third column </td>

if you would like to give a width to second column then
<style>
table{
table-layout:fixed;
width: 100%;
}
table tr th:nth-child(2){
width: 60%;
}
</style>
Please look that we style the th not the td.
TextView textView = (TextView) spinActSubTask.getSelectedView().findViewById(R.id.tvProduct);
String subItem = textView.getText().toString();
Your line:
img = cv2.rectangle(img,(x,y),(x+w,y+h),(255,0,0),2)
will draw a rectangle in the image, but the return value will be None, so img changes to None and cannot be drawn.
Try
cv2.rectangle(img,(x,y),(x+w,y+h),(255,0,0),2)
I have different approach on ReplaceTextBetween() function.
public static string ReplaceTextBetween(this string strSource, string strStart, string strEnd, string strReplace)
{
if (strSource.Contains(strStart) && strSource.Contains(strEnd))
{
var startIndex = strSource.IndexOf(strStart, 0) + strStart.Length;
var endIndex = strSource.IndexOf(strEnd, startIndex);
var strSourceLength = strSource.Length;
var strToReplace = strSource.Substring(startIndex, endIndex - startIndex);
var concatStart = startIndex + strToReplace.Length;
var beforeReplaceStr = strSource.Substring(0, startIndex);
var afterReplaceStr = strSource.Substring(concatStart, strSourceLength - endIndex);
return string.Concat(beforeReplaceStr, strReplace, afterReplaceStr);
}
return strSource;
}
The @Url.Action()
method is proccess on the server-side
, so you cannot pass a client-side
value to this function as a parameter. You can concat the client-side
variables with the server-side
url generated by this method, which is a string on the output. Try something like this:
var firstname = "abc";
var username = "abcd";
location.href = '@Url.Action("Display", "Customer")?uname=' + firstname + '&name=' + username;
The @Url.Action("Display", "Customer")
is processed on the server-side
and the rest of the string is processed on the client-side
, concatenating the result of the server-side
method with the client-side
.
if this code does not work even under document ready, most probable you assigned a return false;
somewhere in your js file to that button, if it is button try to change it to a ,span, anchor or div and test if it is working.
$(document).on("click","#test-element",function() {
alert("click bound to document listening for #test-element");
});
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy MM dd");
String text = date.toString(formatter);
LocalDate date = LocalDate.parse(text, formatter);
I believe this might help, you may need to use some sort of localdate variation instead of instant
Maybe this can help :)

As above mentioned, there is no special command to do it. However, if all those connection are inactive, using 'flush tables;' is able to release all those connection which are not active.
In my case, this error was due to incorrect paths used to specify intents in my preferences xml file after I renamed the project. For instance, where I had:
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
<Preference
android:key="pref_edit_recipe_key"
android:title="Add/Edit Recipe">
<intent
android:action="android.intent.action.VIEW"
android:targetPackage="com.ssimon.olddirectory"
android:targetClass="com.ssimon.olddirectory.RecipeEditActivity"/>
</Preference>
</PreferenceScreen>
I needed the following instead:
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
<Preference
android:key="pref_edit_recipe_key"
android:title="Add/Edit Recipe">
<intent
android:action="android.intent.action.VIEW"
android:targetPackage="com.ssimon.newdirectory"
android:targetClass="com.ssimon.newdirectory.RecipeEditActivity"/>
</Preference>
Correcting the path names fixed the problem.
The best way is to use fixtures.
Note: Keep in mind that fixtures do direct inserts and don't use your model so if you have callbacks that populate data you will need to find a workaround.
In addition, If you know your code should not work if object is null, you can throw exception by using Optional.orElseThrow
String nullName = null;
String name = Optional.ofNullable(nullName)
.orElseThrow(NullPointerException::new);
// .orElseThrow(CustomException::new);
I usually find myself needing something that also skips the value if that value is null
or undefined
, etc.
So here is the solution that works for me:
// Example 1
const arr1 = ['apple', null, 'banana', '', undefined, 'pear'];
const commaSeparated1 = arr1.filter(item => item).join(', ');
console.log(commaSeparated1); // 'apple, banana, pear'
// Example 2
const arr2 = [null, 'apple'];
const commaSeparated2 = arr2.filter(item => item).join(', ');
console.log(commaSeparated2); // 'apple'
Most of the solutions here would return ', apple'
if my array would look like the one in my second example. That's why I prefer this solution.
While the answer given by Paul H shows the essential part, it is not a complete example. On the other hand the matplotlib example seems rather complicated and does not show how to use days.
So for everyone in need here is a full working example:
from datetime import datetime
import matplotlib.pyplot as plt
from matplotlib.dates import DateFormatter
myDates = [datetime(2012,1,i+3) for i in range(10)]
myValues = [5,6,4,3,7,8,1,2,5,4]
fig, ax = plt.subplots()
ax.plot(myDates,myValues)
myFmt = DateFormatter("%d")
ax.xaxis.set_major_formatter(myFmt)
## Rotate date labels automatically
fig.autofmt_xdate()
plt.show()
As an extension to @VinaySajip answer. There are additional nargs
worth mentioning.
parser.add_argument('dir', nargs=1, default=os.getcwd())
N (an integer). N arguments from the command line will be gathered together into a list
parser.add_argument('dir', nargs='*', default=os.getcwd())
'*'. All command-line arguments present are gathered into a list. Note that it generally doesn't make much sense to have more than one positional argument with nargs='*'
, but multiple optional arguments with nargs='*'
is possible.
parser.add_argument('dir', nargs='+', default=os.getcwd())
'+'. Just like '*', all command-line args present are gathered into a list. Additionally, an error message will be generated if there wasn’t at least one command-line argument present.
parser.add_argument('dir', nargs=argparse.REMAINDER, default=os.getcwd())
argparse.REMAINDER
. All the remaining command-line arguments are gathered into a list. This is commonly useful for command line utilities that dispatch to other command line utilities
If the nargs
keyword argument is not provided, the number of arguments consumed is determined by the action. Generally this means a single command-line argument will be consumed and a single item (not a list) will be produced.
Edit (copied from a comment by @Acumenus) nargs='?'
The docs say: '?'. One argument will be consumed from the command line if possible and produced as a single item. If no command-line argument is present, the value from default will be produced.
var uniq = allvalues.GroupBy(x => x.Id).Select(y=>y.First()).Distinct();
Easy and simple
Indexing a list is done using double bracket, i.e. hypo_list[[1]]
(e.g. have a look here: http://www.r-tutor.com/r-introduction/list). BTW: read.table
does not return a table but a dataframe (see value section in ?read.table
). So you will have a list of dataframes, rather than a list of table objects. The principal mechanism is identical for tables and dataframes though.
Note: In R, the index for the first entry is a 1
(not 0
like in some other languages).
Dataframes
l <- list(anscombe, iris) # put dfs in list
l[[1]] # returns anscombe dataframe
anscombe[1:2, 2] # access first two rows and second column of dataset
[1] 10 8
l[[1]][1:2, 2] # the same but selecting the dataframe from the list first
[1] 10 8
Table objects
tbl1 <- table(sample(1:5, 50, rep=T))
tbl2 <- table(sample(1:5, 50, rep=T))
l <- list(tbl1, tbl2) # put tables in a list
tbl1[1:2] # access first two elements of table 1
Now with the list
l[[1]] # access first table from the list
1 2 3 4 5
9 11 12 9 9
l[[1]][1:2] # access first two elements in first table
1 2
9 11
If you need subsecond precision, you need to use system-specific extensions, and will have to check with the documentation for the operating system. POSIX supports up to microseconds with gettimeofday, but nothing more precise since computers didn't have frequencies above 1GHz.
If you are using Boost, you can check boost::posix_time.
Use \b
for word boundaries:
sed -i 's/\boldtext\b/newtext/g' <file>
You could use a projection with a statement lambda, but the original foreach
loop is more readable and is editing the list in place rather than creating a new list.
var result = list.Select(i =>
{
if (i.Name == "height") i.Value = 30;
return i;
}).ToList();
Extension Method
public static IEnumerable<MyClass> SetHeights(
this IEnumerable<MyClass> source, int value)
{
foreach (var item in source)
{
if (item.Name == "height")
{
item.Value = value;
}
yield return item;
}
}
var result = list.SetHeights(30).ToList();
This code is Kotlin version. I have another idea to add a random shuffle integer in last digit for giving variance epoch time.
Kotlin version
val randomVariance = (0..100).shuffled().first()
val currentEpoch = (System.currentTimeMilis()/1000) + randomVariance
val deltaEpoch = oldEpoch - currentEpoch
I think it will be better using this kode then depend on android version 26 or more
You can use the condition if x is not null then...
. It's not a function. There's also the NVL()
function, a good example of usage here: NVL function ref.
//x=address or src
if(x.includes('/')==true){xp=x.split('/')} //split address
if(x.includes('\\')==true){xp=x.split('\\')} //split address
xl=xp.length*1-1;xn=xp[xl] //file==xn
xo=xn.split('.'); //file parts=xo
if(xo.lenght>2){xol=xo.length-1;xt=xo[xol];xr=xo.splice(xol,1);
xr=xr.join('.'); // multiple . in name
}else{
xr=xo[0]; //filename=xr
xt=xo[1]; //file ext=xt
}
xp.splice(xl,1); //remove file
xf=xp.join('/'); //folder=xf , also corrects slashes
//result
alert("filepath: "+x+"\n folder: "+xf+"("+xl+")\n file: "+xn+"\n filename: "+xr+"\n .ext: "+xt)
The tutorial @Henrik mentioned is an excellent resource for learning how to create plots with the ggplot2
package.
An example with your data:
# transforming the data from wide to long
library(reshape2)
dfm <- melt(df, id = "TY")
# creating a scatterplot
ggplot(data = dfm, aes(x = TY, y = value, color = variable)) +
geom_point(size=5) +
labs(title = "Temperatures\n", x = "TY [°C]", y = "Txxx", color = "Legend Title\n") +
scale_color_manual(labels = c("T999", "T888"), values = c("blue", "red")) +
theme_bw() +
theme(axis.text.x = element_text(size = 14), axis.title.x = element_text(size = 16),
axis.text.y = element_text(size = 14), axis.title.y = element_text(size = 16),
plot.title = element_text(size = 20, face = "bold", color = "darkgreen"))
this results in:
As mentioned by @user2739472 in the comments: If you only want to change the legend text labels and not the colours from ggplot's default palette, you can use scale_color_hue(labels = c("T999", "T888"))
instead of scale_color_manual()
.
I use this
this.$refs['refFormName'].resetFields();
this work fine for me.
They both work the same. However, note that if both are defined, only one of them will be invoked. I generally avoid using either of them directly. Instead, you can attach an event handler to the load event. This way you can incorporate more easily other JS packages which might also need to attach a callback to the onload event.
Any JS framework will have cross-browser methods for event handlers.
EDIT: I realized as soon as I posed that this really only works for sets -- it will not properly deal with collections that have duplicate items. For example { 1, 1, 2 } and { 2, 2, 1 } will be considered equal from this algorithm's perspective. If your collections are sets (or their equality can be measured that way), however, I hope you find the below useful.
The solution I use is:
return c1.Count == c2.Count && c1.Intersect(c2).Count() == c1.Count;
Linq does the dictionary thing under the covers, so this is also O(N). (Note, it's O(1) if the collections aren't the same size).
I did a sanity check using the "SetEqual" method suggested by Daniel, the OrderBy/SequenceEquals method suggested by Igor, and my suggestion. The results are below, showing O(N*LogN) for Igor and O(N) for mine and Daniel's.
I think the simplicity of the Linq intersect code makes it the preferable solution.

Don't do this, but this is how you would do it:
$(".overdue").each(function() {
alert("Your book is overdue");
});
The reason I say "don't do it" is because nothing is more annoying to users, in my opinion, than repeated pop-ups that cannot be stopped. Instead, just use the length
property and let them know that "You have X books overdue".
So in essence, it sounds like the answer could depend on how the request is formed.
If the requested resource forms part of the URI as per a request to http://mywebsite/restapi/user/13
and user 13 does not exist, then a 404 is probably appropriate and intuitive because the URI is representative of a non-existent user/entity/document/etc. The same would hold for the more secure technique using a GUID http://mywebsite/api/user/3dd5b770-79ea-11e1-b0c4-0800200c9a66
and the api/restapi argument above.
However, if the requested resource ID was included in the request header [include your own example], or indeed, in the URI as a parameter, eg http://mywebsite/restapi/user/?UID=13
then the URI would still be correct (because the concept of a USER does exits at http://mywebsite/restapi/user/
); and therefore the response could reasonable be expected to be a 200 (with an appropriately verbose message) because the specific user known as 13 does not exist but the URI does. This way we are saying the URI is good, but the request for data has no content.
Personally a 200 still doesn't feel right (though I have previously argued it does). A 200 response code (without a verbose response) could cause an issue not to be investigated when an incorrect ID is sent for example.
A better approach would be to send a 204 - No Content
response. This is compliant with w3c's description *The server has fulfilled the request but does not need to return an entity-body, and might want to return updated metainformation.*1 The confusion, in my opinion is caused by the Wikipedia entry stating 204 No Content - The server successfully processed the request, but is not returning any content. Usually used as a response to a successful delete request. The last sentence is highly debateable. Consider the situation without that sentence and the solution is easy - just send a 204 if the entity does not exist. There is even an argument for returning a 204 instead of a 404, the request has been processed and no content has been returned! Please be aware though, 204's do not allow content in the response body

You should not use your domain models
in your views. ViewModels
are the correct way to do it.
You need to map your domain model's necessary fields to viewmodel and then use this viewmodel in your controllers. This way you will have the necessery abstraction in your application.
If you never heard of viewmodels, take a look at this.
Follow the below steps in Eclipse.
Check here for more information : How to use web camera in android emulator to capture a live image?
Define a maximum size.
Then, compute a resize ratio by taking min(maxwidth/width, maxheight/height)
.
The proper size is oldsize*ratio
.
There is of course also a library method to do this: the method Image.thumbnail
.
Below is an (edited) example from the PIL documentation.
import os, sys
import Image
size = 128, 128
for infile in sys.argv[1:]:
outfile = os.path.splitext(infile)[0] + ".thumbnail"
if infile != outfile:
try:
im = Image.open(infile)
im.thumbnail(size, Image.ANTIALIAS)
im.save(outfile, "JPEG")
except IOError:
print "cannot create thumbnail for '%s'" % infile
I use the method below.
-(UIImage *)getNeedImageFrom:(UIImage*)image cropRect:(CGRect)rect
{
CGSize cropSize = rect.size;
CGFloat widthScale =
image.size.width/self.imageViewOriginal.bounds.size.width;
CGFloat heightScale =
image.size.height/self.imageViewOriginal.bounds.size.height;
cropSize = CGSizeMake(rect.size.width*widthScale,
rect.size.height*heightScale);
CGPoint pointCrop = CGPointMake(rect.origin.x*widthScale,
rect.origin.y*heightScale);
rect = CGRectMake(pointCrop.x, pointCrop.y, cropSize.width,
cropSize.height);
CGImageRef subImage = CGImageCreateWithImageInRect(image.CGImage, rect);
UIImage *croppedImage = [UIImage imageWithCGImage:subImage];
CGImageRelease(subImage);
return croppedImage;
}

Building on alko's answer that almost worked for me, except for the filtering step (where I get: ValueError: cannot reindex from a duplicate axis
), here is the final solution I used:
# join the dataframes
united_data = pd.concat([data1, data2, data3, ...])
# group the data by the whole row to find duplicates
united_data_grouped = united_data.groupby(list(united_data.columns))
# detect the row indices of unique rows
uniq_data_idx = [x[0] for x in united_data_grouped.indices.values() if len(x) == 1]
# extract those unique values
uniq_data = united_data.iloc[uniq_data_idx]
Textarea respects the white-space attribute for the placeholder. https://www.w3schools.com/cssref/pr_text_white-space.asp
Setting it to pre-line solved the problem for me.

white-space: pre-line;_x000D_
}
_x000D_
<textarea placeholder='This is a line _x000D_
should this be a new line'></textarea>

Not /gi but /g

BigInteger is immutable, you need to do this,
BigInteger sum = test.add(new BigInteger(30));
System.out.println(sum);
It depends on your situation.
I would say, if your bool has a good name, then:
if (control.IsEnabled) // Read "If control is enabled."
{
}
would be preferred.
If, however, the variable has a not-so-obvious name, checking against true
would be helpful in understanding the logic.
if (first == true) // Read "If first is true."
{
}
You can try to use that class. The limitation is that it can't be used outside of one process.

$*
Expands to the positional parameters, starting from one. When the expansion occurs within double quotes, it expands to a single word with the value of each parameter separated by the first character of the IFS special variable. That is, "$*" is equivalent to "$1c$2c...", where c is the first character of the value of the IFS variable. If IFS is unset, the parameters are separated by spaces. If IFS is null, the parameters are joined without intervening separators.
$@
Expands to the positional parameters, starting from one. When the expansion occurs within double quotes, each parameter expands to a separate word. That is, "$@" is equivalent to "$1" "$2" ... If the double-quoted expansion occurs within a word, the expansion of the first parameter is joined with the beginning part of the original word, and the expansion of the last parameter is joined with the last part of the original word. When there are no positional parameters, "$@" and $@ expand to nothing (i.e., they are removed).

myArray = [1, 2, 3]
len(myArray)
Output:

Random function from the sql could help. Also if you would like to limit to just one row, just add that in the end.
SELECT column FROM table
ORDER BY RAND()
LIMIT 1
My solutions is to determine timezone adjustment the browser applies, and reverse it:
var timestamp = 1600913205; //retrieved from unix, that is why it is in seconds
//uncomment below line if you want to apply Pacific timezone
//timestamp += -25200;
//determine the timezone offset the browser applies to Date()
var offset = (new Date()).getTimezoneOffset() * 60;
//re-initialize the Date function to reverse the timezone adjustment
var date = new Date((timestamp + offset) * 1000);
//here continue using date functions.
This point the date will be timezone free and always UTC, You can apply your own offset to timestamp to produce any timezone.
I found a much simpler alternative way to generating soap message. Given a Person Object:
import com.fasterxml.jackson.annotation.JsonInclude;
@JsonInclude(JsonInclude.Include.NON_NULL)
public class Person {
private String name;
private int age;
private String address; //setter and getters below
}
Below is a simple Soap Message Generator:
import com.fasterxml.jackson.databind.DeserializationFeature;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.SerializationFeature;
import com.fasterxml.jackson.datatype.jsr310.JavaTimeModule;
import lombok.extern.slf4j.Slf4j;
import org.apache.commons.lang3.StringUtils;
import com.fasterxml.jackson.dataformat.xml.XmlMapper;
@Slf4j
public class SoapGenerator {
protected static final ObjectMapper XML_MAPPER = new XmlMapper()
.enable(DeserializationFeature.READ_UNKNOWN_ENUM_VALUES_AS_NULL)
.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false)
.configure(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS, false)
.registerModule(new JavaTimeModule());
private static final String SOAP_BODY_OPEN = "<soap:Body>";
private static final String SOAP_BODY_CLOSE = "</soap:Body>";
private static final String SOAP_ENVELOPE_OPEN = "<soap:Envelope xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">";
private static final String SOAP_ENVELOPE_CLOSE = "</soap:Envelope>";
public static String soapWrap(String xml) {
return SOAP_ENVELOPE_OPEN + SOAP_BODY_OPEN + xml + SOAP_BODY_CLOSE + SOAP_ENVELOPE_CLOSE;
}
public static String soapUnwrap(String xml) {
return StringUtils.substringBetween(xml, SOAP_BODY_OPEN, SOAP_BODY_CLOSE);
}
}
You can use by:
public static void main(String[] args) throws Exception{
Person p = new Person();
p.setName("Test");
p.setAge(12);
String xml = SoapGenerator.soapWrap(XML_MAPPER.writeValueAsString(p));
log.info("Generated String");
log.info(xml);
}
In SQL Server 2008 you can use
http://www.sommarskog.se/share_data.html#tableparam
or else simple and same as common execution
CREATE PROCEDURE OrderSummary @MaxQuantity INT OUTPUT AS
SELECT Ord.EmployeeID, SummSales = SUM(OrDet.UnitPrice * OrDet.Quantity)
FROM Orders AS Ord
JOIN [Order Details] AS OrDet ON (Ord.OrderID = OrDet.OrderID)
GROUP BY Ord.EmployeeID
ORDER BY Ord.EmployeeID
SELECT @MaxQuantity = MAX(Quantity) FROM [Order Details]
RETURN (SELECT SUM(Quantity) FROM [Order Details])
GO
I hopes its help to you
Its all about data which you pass; has to properly formatted string. If you are passing empty data then data: {} will work. However with multiple parameters it has to be properly formatted e.g.
var dataParam = '{' + '"data1Variable": "' + data1Value+ '", "data2Variable": "' + data2Value+ '"' + '}';
....
data : dataParam
...
Best way to understand is have error handler with proper message parameter, so as to know the detailed errors.
What does it mean "media that are designed to deal with textual data"?
Back in the day when ASCII ruled the world dealing with non-ASCII values was a headache. People jumped through all sorts of hoops to get these transferred over the wire without losing out information.
if you provide a bad path or a broken link, if the compiler cannot find the image, the picture box would display an X icon on its body.
PictureBox picture = new PictureBox
{
Name = "pictureBox",
Size = new Size(100, 50),
Location = new Point(14, 17),
Image = Image.FromFile(@"c:\Images\test.jpg"),
SizeMode = PictureBoxSizeMode.CenterImage
};
p.Controls.Add(picture);
OR
PictureBox picture = new PictureBox
{
Name = "pictureBox",
Size = new Size(100, 50),
Location = new Point(14, 17),
ImageLocation = @"c:\Images\test.jpg",
SizeMode = PictureBoxSizeMode.CenterImage
};
p.Controls.Add(picture);
i'm not sure where you put images in your folder structure but you can find the path as bellow
picture.ImageLocation = Path.Combine(System.Windows.Forms.Application.StartupPath, "Resources\Images\1.jpg");

hashCode
Whenever you override equals(), you are also expected to override hashCode(). The hash code is used when storing the object as a key in a map.
A hash code is a number that puts instances of a class into a finite number of categories. Imagine that I gave you a deck of cards, and I told you that I was going to ask you for specific cards and I want to get the right card back quickly. You have as long as you want to prepare, but I’m in a big hurry when I start asking for cards. You might make 13 piles of cards: All of the aces in one pile, all the twos in another pile, and so forth. That way, when I ask for the five of hearts, you can just pull the right card out of the four cards in the pile with fives. It is certainly faster than going through the whole deck of 52 cards! You could even make 52 piles if you had enough space on the table.

This answer by Jaap :
<div class="image"></div>?
and in CSS :
div.image {
content:url(http://placehold.it/350x150);
}?
you can try it on this link : http://jsfiddle.net/XAh2d/
this is a link about css content http://css-tricks.com/css-content/
This has been tested on Chrome, firefox and Safari. (I'm on a mac, so if someone has the result on IE, tell me to add it)
Another way of doing multiple cases in a switch statement, when inside a function:
function name(varName){
switch (varName) {
case 'afshin':
case 'saeed':
case 'larry':
return 'Hey';
default:
return 'Default case';
}
}
console.log(name('afshin')); // Hey

You have said you can only load scripts from your own site (self). You have then tried to load a script from another site (www.google.com) and, because you've restricted this, you can't. That's the whole point of Content Security Policy (CSP).
You can change your first line to:
<meta http-equiv="Content-Security-Policy" content="default-src *; style-src 'self' 'unsafe-inline'; script-src 'self' 'unsafe-inline' 'unsafe-eval' http://www.google.com">
Or, alternatively, it may be worth removing that line completely until you find out more about CSP. Your current CSP is pretty lax anyway (allowing unsafe-inline
, unsafe-eval
and a default-src
of *
), so it is probably not adding too much value, to be honest.
For every field that has choices set, the object will have a get_FOO_display() method, where FOO is the name of the field. This method returns the “human-readable” value of the field.
In Views
person = Person.objects.filter(to_be_listed=True)
context['gender'] = person.get_gender_display()
In Template
{{ person.get_gender_display }}
Late to the game but you can also use the janitor
package. This function will remove columns which are all NA, and can be changed to remove rows that are all NA as well.
df <- janitor::remove_empty(df, which = "cols")
Beginning with Android 3.2 (API level 13), size groups (folders small, normal, large, xlarge) are deprecated in favor of a new technique for managing screen sizes based on the available screen width.
Starting from AngularJS v1.4.8, you can use
get(url, config)
as follows:
var data = {
user_id:user.id
};
var config = {
params: data,
headers : {'Accept' : 'application/json'}
};
$http.get(user.details_path, config).then(function(response) {
// process response here..
}, function(response) {
});
Here is a simple example. I suppose it will be easy to understand:
import java.awt.*;
import javax.swing.JFrame;
import javax.swing.JPanel;
public class Graph extends JFrame {
JFrame f = new JFrame();
JPanel jp;
public Graph() {
f.setTitle("Simple Drawing");
f.setSize(300, 300);
f.setDefaultCloseOperation(EXIT_ON_CLOSE);
jp = new GPanel();
f.add(jp);
f.setVisible(true);
}
public static void main(String[] args) {
Graph g1 = new Graph();
g1.setVisible(true);
}
class GPanel extends JPanel {
public GPanel() {
f.setPreferredSize(new Dimension(300, 300));
}
@Override
public void paintComponent(Graphics g) {
//rectangle originates at 10,10 and ends at 240,240
g.drawRect(10, 10, 240, 240);
//filled Rectangle with rounded corners.
g.fillRoundRect(50, 50, 100, 100, 80, 80);
}
}
}
And the output looks like this:
^[^<>]+$
The caret in the character class ([^
) means match anything but, so this means, beginning of string, then one or more of anything except <
and >
, then the end of the string.
Try invoking your command with Invoke-Expression
:
Invoke-Expression $cmd1
Here is a working example on my machine:
$cmd = "& 'C:\Program Files\7-zip\7z.exe' a -tzip c:\temp\test.zip c:\temp\test.txt"
Invoke-Expression $cmd
iex
is an alias for Invoke-Expression
so you could do:
iex $cmd1

Good Luck...
There are many ways to do this, using common shell utilities.
My solution is:
grep -cve '^\s*$' <file>
This searches for lines in <file> the do not match (-v) lines that match the pattern (-e) '^\s*$', which is the beginning of a line, followed by 0 or more whitespace characters, followed by the end of a line (ie. no content other then whitespace), and display a count of matching lines (-c) instead of the matching lines themselves.
An advantage of this method over methods that involve piping into wc
, is that you can specify multiple files and get a separate count for each file:
$ grep -cve '^\s*$' *.hh
config.hh:36
exceptions.hh:48
layer.hh:52
main.hh:39
Gif's can also be displayed in web view with couple of lines of code and without any 3rd party libraries. This way you can even load the gif from your SD card. No need to copy images to your Asset folder.
Take a web view.
<WebView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/imageWebView" />
Use can open a gif file from SD card not just from asset folder as shown in many examples.
WebView webView = (WebView) findViewById(R.id.imageWebView);
String data = "<body> <img src = \""+ filePath+"\"/></body>";
// 'filePath' is the path of your .GIF file on SD card.
webView.loadDataWithBaseURL("file:///android_asset/",data,"text/html","UTF-8",null);
$row = 1;
$arrResult = array();
if (($handle = fopen("ifsc_code.csv", "r")) !== FALSE) {
while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
$num = count($data);
DB::table('banks')->insert(
array('bank_name' => $data[1], 'ifsc' => $data[2], 'micr' => $data[3], 'branch_name' => $data[4],'address' => $data[5], 'contact' => $data[6], 'city' => $data[7],'district' => $data[8],'state' => $data[9])
);
}
fclose($handle);
}
If you have more than one navigation that is
ParentViewController --> ChildViewController1 --> ChildViewController2
you can use below code to change title of back button on navigation bar.
self.navigationController?.navigationBar.topItem?.backBarButtonItem = UIBarButtonItem.init(title: "Back", style: .plain, target: nil, action:nil)
I've seen
anEvent.isPopupTrigger()
be used before. I'm fairly new to Java so I'm happy to hear thoughts about this approach :)
To my knowledge, there is sadly no CSS filter to colorise an element (perhaps with the use of some SVG filter magic, but I'm somewhat unfamiliar with that) and even if that wasn't the case, filters are basically only supported by webkit browsers.
With that said, you could still work around this and use a canvas
to modify your image. Basically, you can draw an image element onto a canvas and then loop through the pixels, modifying the respective RGBA values to the colour you want.
However, canvases do come with some restrictions. Most importantly, you have to make sure that the image src comes from the same domain as the page. Otherwise the browser won't allow you to read or modify the pixel data of the canvas.
Here's a JSFiddle changing the colour of the JSFiddle logo.

If I use Firefox then screen.width

And yes I tried giving too large numbers too like 10000

and width
but not exactly the maximized effect.
All JavaBeans are POJOs but not all POJOs are JavaBeans.
A JavaBean is a Java object that satisfies certain programming conventions:
dividend % divisor
Dividend is the numeric expression to divide. Dividend must be any expression of integer data type in sql server.
Divisor is the numeric expression to divide the dividend. Divisor must be expression of integer data type except in sql server.
SELECT 15 % 2
Output
1
Dividend = 15
Divisor = 2
Let's say you wanted to query
Query a list of CITY names from STATION with even ID numbers only.
Schema structure for STATION:
ID Number
CITY varchar
STATE varchar
select CITY from STATION as st where st.id % 2 = 0
Will fetch the even set of records
In order to fetch the odd records with Id as odd number.
select CITY from STATION as st where st.id % 2 <> 0
% function reduces the value to either 0 or 1

I needed a batch to run within a Domain environment during the user login process, within a 'workroom' environment, seeing users adhere to a "lock-down" policy and restricted view (mainly distributed via GPO sets).
A Domain GPO set is applied before an AD user linked login script Creating a GPO login script was too per-mature as the users "new" profile hadn't been created/loaded/or ready in time to apply a "remove and/or Pin" taskbar and Start Menu items vbscript + add some local files.
e.g.: The proposed 'default-user' profile environment requires a ".URL' (.lnk) shortcut placed within the "%ProgramData%\Microsoft\Windows\Start Menu\Programs*MyNewOWA.url*", and the "C:\Users\Public\Desktop\*MyNewOWA.url*" locations, amongst other items
The users have multiple machines within the domain, where only these set 'workroom' PCs require these policies.
These folders require 'Admin' rights to modify, and although the 'Domain User' is part of the local 'Admin' group - UAC was the next challenge.
Found various adaptations and amalgamated here. I do have some users with BYOD devices as well that required other files with perm issues. Have not tested on XP (a little too old an OS), but the code is present, would love feed back.

Domain PC's should be governed as much as possible by GPO sets. Workgroup/Standalone machines can be governed by this script.
Remember, a UAC prompt will pop-up at least once with a BYOD workgroup PC (as soon as the first elevating to 'Admin perms' is required), but as the local security policy is modified for admin use from this point on, the pop-ups will disappear.
A Domain PC should have the GPO "ConsentPromptBehaviorAdmin" policy set within your 'already' created "Lock-down" policy - as explained in the script 'REFERENCES' section.
Again, run the secedit.exe import of the default '.inf' file if you are stuck on the whole "To UAC or Not to UAC" debate :-).
btw: @boileau Do check your failure on the:
>nul 2>&1 "%SYSTEMROOT%\system32\cacls.exe" "%SYSTEMROOT%\system32\config\system"
By running only "%SYSTEMROOT%\system32\cacls.exe" or "%SYSTEMROOT%\system32\config\system" or both from the command prompt - elevated or not, check the result across the board.
df.groupby('l_customer_id_i').agg(lambda x: ','.join(x))
does already return a dataframe, so you cannot loop over the groups anymore.
In general:
df.groupby(...)
returns a GroupBy
object (a DataFrameGroupBy or SeriesGroupBy), and with this, you can iterate through the groups (as explained in the docs here). You can do something like:
grouped = df.groupby('A')
for name, group in grouped:
...
When you apply a function on the groupby, in your example df.groupby(...).agg(...)
(but this can also be transform
, apply
, mean
, ...), you combine the result of applying the function to the different groups together in one dataframe (the apply and combine step of the 'split-apply-combine' paradigm of groupby). So the result of this will always be again a DataFrame (or a Series depending on the applied function).
I like RestClient. It encapsulates net/http with cool features like multipart form data:
require 'rest_client'
RestClient.post('http://localhost:3000/foo',
:name_of_file_param => File.new('/path/to/file'))
It also supports streaming.
gem install rest-client
will get you started.

I found that I needed to add some code from a messy sdiff
output in order to clean it up:
sdiff -s column1.txt column2.txt | grep -F '<' | cut -f1 -d"<" > c12diff.txt
sed -n 1'p' c12diff.txt | sed 's/ *$//g' | tr -d '\n' | tr -d '\t'
This removes the trailing spaces and other invisible characters.
just add two lines in your php.ini file.
extension=php_openssl.dll
allow_url_include = On
its working for me.
In latest version, mySQL uses auth_socket
, so to login you've to know about the auto generated user credentials. or if you download binary version, while installation process, you can choose lagacy password
.
To install SQL in linux debian versions
sudo apt install mysql-server
to know about the password
sudo cat /etc/mysql/debian.cnf
Now login
mysql -u debian-sys-maint -p
use the password from debian.cnf
How to see available user records:
USE mysql
SELECT User, Host, plugin FROM mysql.user;
Now you can create a new user. Use the below commands:
use mysql;
CREATE USER 'username'@'localhost' IDENTIFIED BY 'password';
GRANT ALL ON *.* TO 'username'@'localhost';
flush privileges;
To list the grants for the particular mysql user
SHOW GRANTS FOR 'username'@'localhost';
How to revoke all the grants for the particular mysql user
REVOKE ALL PRIVILEGES, GRANT OPTION FROM 'username'@'localhost';
To delete/remove particular user from user account list
DROP USER 'username'@'localhost';
For more commands:
$ man 1 mysql
Please don't reset the password for root, instead create a new user and grant rights. This is the best practice.
type T1 = Omit<XYZ, "z"> // { x: number; y: number; }
type T2 = Omit<XYZ, "y" | "z"> // { x: number; }
type Keys_StringExcluded<T> =
{ [K in keyof T]: T[K] extends string ? never : K }[keyof T]
type XYZ = { x: number; y: string; z: number; }
type T3a = Pick<XYZ, Keys_StringExcluded<XYZ>> // { x: number; z: number; }
Shorter version with TS 4.1 key remapping / as
clause in mapped types (PR):
type T3b = { [K in keyof XYZ as XYZ[K] extends string ? never : K]: XYZ[K] }
// { x: number; z: number; }
string
patterntype OmitGet<T> = {[K in keyof T as K extends `get${infer _}` ? never : K]: T[K]}
type XYZ2 = { getA: number; b: string; getC: boolean; }
type T4 = OmitGet<XYZ2> // { b: string; }
Note: Above template literal types are supported with TS 4.1.
Note 2: You can also write get${string}
instead of get${infer _}
here.

How to Pick and rename certain keys using Typescript? (rename instead of exclude)
You are subscripting a three-dimensional array myArray[10][10][10]
four times myArray[i][t][x][y]
. You will probably need to add another dimension to your array. Also consider a container like Boost.MultiArray, though that's probably over your head at this point.
It doesn't matter is your app Boot or just raw Spring. There is just enough to inject org.springframework.core.env.Environment
to your bean.
@Autowired
private Environment environment;
....
this.environment.getActiveProfiles();
One more important thing to realise: if you see iso-8859-1
, it probably refers to Windows-1252 rather than ISO/IEC 8859-1. They differ in the range 0x80–0x9F, where ISO 8859-1 has the C1 control codes, and Windows-1252 has useful visible characters instead.
For example, ISO 8859-1 has 0x85 as a control character (in Unicode, U+0085, ``), while Windows-1252 has a horizontal ellipsis (in Unicode, U+2026 HORIZONTAL ELLIPSIS, …
).
The WHATWG Encoding spec (as used by HTML) expressly declares iso-8859-1
to be a label for windows-1252
, and web browsers do not support ISO 8859-1 in any way: the HTML spec says that all encodings in the Encoding spec must be supported, and no more.
Also of interest, HTML numeric character references essentially use Windows-1252 for 8-bit values rather than Unicode code points; per https://html.spec.whatwg.org/#numeric-character-reference-end-state, …
will produce U+2026 rather than U+0085.
System properties are set on the Java command line using the -Dpropertyname=value
syntax. They can also be added at runtime
using System.setProperty(String key, String value)
or via the various
System.getProperties().load()
methods.
To get a specific system property you can use System.getProperty(String key)
or System.getProperty(String key, String def)
.
Environment variables are set in the OS, e.g. in Linux export HOME=/Users/myusername
or on Windows SET WINDIR=C:\Windows
etc,
and, unlike properties, may not be set at runtime.
To get a specific environment variable you can use System.getenv(String name)
.
You have to decide as which parameter you want to treat a single argument. You cannot treat it as both, content
and options
.
I see two possibilities:
function(options, content)
Check whether options
is defined:
function(content, options) {
if(typeof options === "undefined") {
options = content;
content = null;
}
//action
}
But then you have to document properly, what happens if you only pass one argument to the function, as this is not immediately clear by looking at the signature.
In case you don't know it already, Oracle has released ODP.NET which supports Entity Framework. It doesn't support code first yet though.

Thanks RedFilter for providing excellent solution to the bugging issue of sorting nullable datetime field.
I am using SQL Server database for my project.
Changing the datetime null value to '1' does solves the problem of sorting for datetime datatype column. However if we have column with other than datetime datatype then it fails to handle.
To handle a varchar column sort, I tried using 'ZZZZZZZ' as I knew the column does not have values beginning with 'Z'. It worked as expected.
On the same lines, I used max values +1 for int and other data types to get the sort as expected. This also gave me the results as were required.
However, it would always be ideal to get something easier in the database engine itself that could do something like:
Order by Col1 Asc Nulls Last, Col2 Asc Nulls First
As mentioned in the answer provided by a_horse_with_no_name.
Bit old, but doesn't hurt to add some notes.
When you write something like this
let a: any;
let b: Object;
let c: {};
And that's why
a.doSomething(); // Ok: the compiler trusts you on that
b.doSomething(); // Error: Object has no doSomething member
c.doSomething(); // Error: c neither has doSomething nor inherits it from Object
and why
a.toString(); // Ok: whatever, dude, have it your way
b.toString(); // Ok: toString is defined in Object
c.toString(); // Ok: c inherits toString from Object
So Object
and {}
are equivalents in TypeScript.
If you declare functions like these
function fa(param: any): void {}
function fb(param: Object): void {}
with the intention of accepting anything for param (maybe you're going to check types at run-time to decide what to do with it), remember that
It is worth noting, though, that if param is supposed to accept multiple known types, a better approach is to declare it using union types, as in
function fc(param: string|number): void {}
Obviously, OO inheritance rules still apply, so if you want to accept instances of derived classes and treat them based on their base type, as in
interface IPerson {
gender: string;
}
class Person implements IPerson {
gender: string;
}
class Teacher extends Person {}
function func(person: IPerson): void {
console.log(person.gender);
}
func(new Person()); // Ok
func(new Teacher()); // Ok
func({gender: 'male'}); // Ok
func({name: 'male'}); // Error: no gender..
the base type is the way to do it, not any. But that's OO, out of scope, I just wanted to clarify that any should only be used when you don't know whats coming, and for anything else you should annotate the correct type.
UPDATE:
Typescript 2.2 added an object
type, which specifies that a value is a non-primitive: (i.e. not a number
, string
, boolean
, symbol
, undefined
, or null
).
Consider functions defined as:
function b(x: Object) {}
function c(x: {}) {}
function d(x: object) {}
x
will have the same available properties within all of these functions, but it's a type error to call d
with a primitive:
b("foo"); //Okay
c("foo"); //Okay
d("foo"); //Error: "foo" is a primitive
You can use the pseudo-selector :checkbox
with a call to jQuery's is
function:
$('#myinput').is(':checkbox')
My preference, and I have no idea why this isn't already in jQuery:
$.fn.orElse = function(elseFunction) {
if (!this.length) {
elseFunction();
}
};
Used like this:
$('#notAnElement').each(function () {
alert("Wrong, it is an element")
}).orElse(function() {
alert("Yup, it's not an element")
});
Or, as it looks in CoffeeScript:
$('#notAnElement').each ->
alert "Wrong, it is an element"; return
.orElse ->
alert "Yup, it's not an element"
Simply call jQuery's toggleClass()
on the i
element contained within your a
element(s) to toggle either the plus and minus icons:
...click(function() {
$(this).find('i').toggleClass('fa-minus-circle fa-plus-circle');
});
Note that this assumes that a class of fa-plus-circle
is added to your i
element by default.
Numbers inherit from the Number
constructor which doesn't have the .toLowerCase
method. You can look it up as a matter of fact:
"toLowerCase" in Number.prototype; // false
The source release is the raw, uncompiled code. You could read it yourself. To use it, it must be compiled on your machine. Binary means the code was compiled into a machine language format that the computer can read, then execute. No human can understand the binary file unless its been dissected, or opened with some program that let's you read the executable as code.
A more generic solution for might be the following.
extendDf <- function (df, n) {
withFactors <- sum(sapply (df, function(X) (is.factor(X)) )) > 0
nr <- nrow (df)
colNames <- names(df)
for (c in 1:length(colNames)) {
if (is.factor(df[,c])) {
col <- vector (mode='character', length = nr+n)
col[1:nr] <- as.character(df[,c])
col[(nr+1):(n+nr)]<- rep(col[1], n) # to avoid extra levels
col <- as.factor(col)
} else {
col <- vector (mode=mode(df[1,c]), length = nr+n)
class(col) <- class (df[1,c])
col[1:nr] <- df[,c]
}
if (c==1) {
newDf <- data.frame (col ,stringsAsFactors=withFactors)
} else {
newDf[,c] <- col
}
}
names(newDf) <- colNames
newDf
}
The function extendDf() extends a data frame with n rows.
As an example:
aDf <- data.frame (l=TRUE, i=1L, n=1, c='a', t=Sys.time(), stringsAsFactors = TRUE)
extendDf (aDf, 2)
# l i n c t
# 1 TRUE 1 1 a 2016-07-06 17:12:30
# 2 FALSE 0 0 a 1970-01-01 01:00:00
# 3 FALSE 0 0 a 1970-01-01 01:00:00
system.time (eDf <- extendDf (aDf, 100000))
# user system elapsed
# 0.009 0.002 0.010
system.time (eDf <- extendDf (eDf, 100000))
# user system elapsed
# 0.068 0.002 0.070
In jQuery just use:
$('#tblOne > tbody > tr').each(function() {...code...});
Using the children selector (>
) you will walk over all the children (and not all descendents), example with three rows:
$('table > tbody > tr').each(function(index, tr) {
console.log(index);
console.log(tr);
});
Result:
0
<tr>
1
<tr>
2
<tr>
In VanillaJS you can use document.querySelectorAll()
and walk over the rows using forEach()
[].forEach.call(document.querySelectorAll('#tblOne > tbody > tr'), function(index, tr) {
/* console.log(index); */
/* console.log(tr); */
});
First I think you need to fix your lists, as the first node of a <ul>
must be a <li>
(stackoverflow ref). Once that is setup you can do this:
// note this array has outer scope
var phrases = [];
$('.phrase').each(function(){
// this is inner scope, in reference to the .phrase element
var phrase = '';
$(this).find('li').each(function(){
// cache jquery var
var current = $(this);
// check if our current li has children (sub elements)
// if it does, skip it
// ps, you can work with this by seeing if the first child
// is a UL with blank inside and odd your custom BLANK text
if(current.children().size() > 0) {return true;}
// add current text to our current phrase
phrase += current.text();
});
// now that our current phrase is completely build we add it to our outer array
phrases.push(phrase);
});
// note the comma in the alert shows separate phrases
alert(phrases);
Working jsfiddle.
One thing is if you get the .text()
of an upper level li
you will get all sub level text with it.
Keeping an array will allow for many multiple phrases to be extracted.
EDIT:
This should work better with an empty UL
with no LI
:
// outer scope
var phrases = [];
$('.phrase').each(function(){
// inner scope
var phrase = '';
$(this).find('li').each(function(){
// cache jquery object
var current = $(this);
// check for sub levels
if(current.children().size() > 0) {
// check is sublevel is just empty UL
var emptyULtest = current.children().eq(0);
if(emptyULtest.is('ul') && $.trim(emptyULtest.text())==""){
phrase += ' -BLANK- '; //custom blank text
return true;
} else {
// else it is an actual sublevel with li's
return true;
}
}
// if it gets to here it is actual li
phrase += current.text();
});
phrases.push(phrase);
});
// note the comma to separate multiple phrases
alert(phrases);

I was curious if I could beat the accepted answer's time with a one line stringify approach:
I tried 5 methods, none previously mentioned - all one liner - all producing correct answers - and I couldn't come close.
So... to save you the trouble and perhaps fulfill curiosity:
import json
import yaml
import time
from ast import literal_eval as literal
def merge_two_dicts(x, y):
z = x.copy() # start with x's keys and values
z.update(y) # modifies z with y's keys and values & returns None
return z
x = {'a':1, 'b': 2}
y = {'b':10, 'c': 11}
start = time.time()
for i in range(10000):
z = yaml.load((str(x)+str(y)).replace('}{',', '))
elapsed = (time.time()-start)
print (elapsed, z, 'stringify yaml')
start = time.time()
for i in range(10000):
z = literal((str(x)+str(y)).replace('}{',', '))
elapsed = (time.time()-start)
print (elapsed, z, 'stringify literal')
start = time.time()
for i in range(10000):
z = eval((str(x)+str(y)).replace('}{',', '))
elapsed = (time.time()-start)
print (elapsed, z, 'stringify eval')
start = time.time()
for i in range(10000):
z = {k:int(v) for k,v in (dict(zip(
((str(x)+str(y))
.replace('}',' ')
.replace('{',' ')
.replace(':',' ')
.replace(',',' ')
.replace("'",'')
.strip()
.split(' '))[::2],
((str(x)+str(y))
.replace('}',' ')
.replace('{',' ').replace(':',' ')
.replace(',',' ')
.replace("'",'')
.strip()
.split(' '))[1::2]
))).items()}
elapsed = (time.time()-start)
print (elapsed, z, 'stringify replace')
start = time.time()
for i in range(10000):
z = json.loads(str((str(x)+str(y)).replace('}{',', ').replace("'",'"')))
elapsed = (time.time()-start)
print (elapsed, z, 'stringify json')
start = time.time()
for i in range(10000):
z = merge_two_dicts(x, y)
elapsed = (time.time()-start)
print (elapsed, z, 'accepted')
results:
7.693928956985474 {'c': 11, 'b': 10, 'a': 1} stringify yaml

What I did learn from this is that JSON approach is the fastest way (of those attempted) to return a dictionary from string-of-dictionary; much faster (about 1/4th of the time) of what I considered to be the normal method using ast
. I also learned that, the YAML approach should be avoided at all cost.
Yes, I understand that this is not the best/correct way. I was curious if it was faster, and it isn't; I posted to prove it so.
Also, this could make it works:
@{
Html.RenderPartial("your view", your_model, ViewData);
}
or
@{
Html.RenderPartial("your view", your_model);
}

Let's take a look at the start
command.
Open Windows command prompt
To open a new Chrome window (blank), type the following:
start chrome --new-window
or
start chrome
To open a URL in Chrome, type the following:
start chrome --new-window "http://www.iot.qa/2018/02/narrowband-iot.html"
To open a URL in Chrome in incognito mode, type the following:
start chrome --new-window --incognito "http://www.iot.qa/2018/02/narrowband-iot.html"
or
start chrome --incognito "http://www.iot.qa/2018/02/narrowband-iot.html"
The problem is that you have a circular import: in app.py
from mod_login import mod_login
in mod_login.py
from app import app
This is not permitted in Python. See Circular import dependency in Python for more info. In short, the solution are
string.Split()
returns an array - you can convert it to a list using ToList()
:
listStrLineElements = line.Split(',').ToList();
Note that you need to import System.Linq
to access the .ToList()
function.
You can use os.system function for simplicity and to invoke bash to accomplish the task:
import os
os.system('mv old_filename new_filename')
That is the correct way to convert it to an INT as long as you don't have any alpha characters or NULL values.
If you have any NULL values, use
ISNULL(column1, 0)
'profiles'
from the table 'django_migrations'
.python manage.py makemigrations
and python manage.py migrate
command.If you are java 1.6 then the following can also be done:
import javax.tools.JavaCompiler;
import javax.tools.ToolProvider;
public class CompilerExample {
public static void main(String[] args) {
String fileToCompile = "/Users/rupas/VolatileExample.java";
JavaCompiler compiler = ToolProvider.getSystemJavaCompiler();
int compilationResult = compiler.run(null, null, null, fileToCompile);
if (compilationResult == 0) {
System.out.println("Compilation is successful");
} else {
System.out.println("Compilation Failed");
}
}
}
INSERT
statements that useVALUES
syntax can insert multiple rows. To do this, include multiple lists of column values, each enclosed within parentheses and separated by commas.
Example:
INSERT INTO tbl_name
(a,b,c)
VALUES
(1,2,3),
(4,5,6),
(7,8,9);
background-image
takes multiple values.
so a combination of just 1 color linear-gradient and css blend modes
will do the trick.
.testclass {
background-image: url("../images/image.jpg"), linear-gradient(rgba(0,0,0,0.5),rgba(0,0,0,0.5));
background-blend-mode: overlay;
}
note that there is no support on IE/Edge for CSS blend-modes at all.
Here is another, very manual solution. You can define the size of the axis and paddings are considered accordingly (including legend and tickmarks). Hope it is of use to somebody.
Example (axes size are the same!):
Code:

$()
means: "first evaluate this, and then evaluate the rest of the line".
Ex :
echo $(pwd)/myFile.txt
will be interpreted as
echo /my/path/myFile.txt
On the other hand ${}
expands a variable.
Ex:
MY_VAR=toto
echo ${MY_VAR}/myFile.txt
will be interpreted as
echo toto/myFile.txt
Why can't I use it as
bash$ while ((i=0;i<10;i++)); do echo $i; done
I'm afraid the answer is just that the bash syntax for while
just isn't the same as the syntax for for
.
Typically you want to cancel the previous ajax request and ignore it's coming response, only when a new ajax request of that instance is started, for this purpose, do the following:
Example: getting some comments from API:
// declare an ajax request's cancelToken (globally)
let ajaxRequest = null;
function getComments() {
// cancel previous ajax if exists
if (ajaxRequest ) {
ajaxRequest.cancel();
}
// creates a new token for upcomming ajax (overwrite the previous one)
ajaxRequest = axios.CancelToken.source();
return axios.get('/api/get-comments', { cancelToken: ajaxRequest.token }).then((response) => {
console.log(response.data)
}).catch(function(err) {
if (axios.isCancel(err)) {
console.log('Previous request canceled, new request is send', err.message);
} else {
// handle error
}
});
}
If using the Win32 API you can use the FindFirstFile and FindNextFile functions.
http://msdn.microsoft.com/en-us/library/aa365200(VS.85).aspx
For recursive traversal of directories you must inspect each WIN32_FIND_DATA.dwFileAttributes to check if the FILE_ATTRIBUTE_DIRECTORY bit is set. If the bit is set then you can recursively call the function with that directory. Alternatively you can use a stack for providing the same effect of a recursive call but avoiding stack overflow for very long path trees.
#include <windows.h>
#include <string>
#include <vector>
#include <stack>
#include <iostream>
using namespace std;
bool ListFiles(wstring path, wstring mask, vector<wstring>& files) {
HANDLE hFind = INVALID_HANDLE_VALUE;
WIN32_FIND_DATA ffd;
wstring spec;
stack<wstring> directories;
directories.push(path);
files.clear();
while (!directories.empty()) {
path = directories.top();
spec = path + L"\\" + mask;
directories.pop();
hFind = FindFirstFile(spec.c_str(), &ffd);
if (hFind == INVALID_HANDLE_VALUE) {
return false;
}
do {
if (wcscmp(ffd.cFileName, L".") != 0 &&
wcscmp(ffd.cFileName, L"..") != 0) {
if (ffd.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY) {
directories.push(path + L"\\" + ffd.cFileName);
}
else {
files.push_back(path + L"\\" + ffd.cFileName);
}
}
} while (FindNextFile(hFind, &ffd) != 0);
if (GetLastError() != ERROR_NO_MORE_FILES) {
FindClose(hFind);
return false;
}
FindClose(hFind);
hFind = INVALID_HANDLE_VALUE;
}
return true;
}
int main(int argc, char* argv[])
{
vector<wstring> files;
if (ListFiles(L"F:\\cvsrepos", L"*", files)) {
for (vector<wstring>::iterator it = files.begin();
it != files.end();
++it) {
wcout << it->c_str() << endl;
}
}
return 0;
}
You are missing an opening quote on the id= and you have a semi-colon after the function declaration. Also, the input tag does not need a closing tag.
This works:
<input onclick="change()" type="button" value="Open Curtain" id="myButton1">
<script type="text/javascript">
function change()
{
document.getElementById("myButton1").value="Close Curtain";
}
</script>
Your JSON is not correct. Instead of
JSONObject cred = new JSONObject();
JSONObject auth=new JSONObject();
JSONObject parent=new JSONObject();
cred.put("username","adm");
cred.put("password", "pwd");
auth.put("tenantName", "adm");
auth.put("passwordCredentials", cred.toString()); // <-- toString()
parent.put("auth", auth.toString()); // <-- toString()
OutputStreamWriter wr= new OutputStreamWriter(con.getOutputStream());
wr.write(parent.toString());
write
JSONObject cred = new JSONObject();
JSONObject auth=new JSONObject();
JSONObject parent=new JSONObject();
cred.put("username","adm");
cred.put("password", "pwd");
auth.put("tenantName", "adm");
auth.put("passwordCredentials", cred);
parent.put("auth", auth);
OutputStreamWriter wr= new OutputStreamWriter(con.getOutputStream());
wr.write(parent.toString());
So, the JSONObject.toString() should be called only once for the outer object.
Another thing (most probably not your problem, but I'd like to mention it):
To be sure not to run into encoding problems, you should specify the encoding, if it is not UTF-8
:
con.setRequestProperty("Content-Type", "application/json; charset=UTF-8");
con.setRequestProperty("Accept", "application/json");
// ...
OutputStream os = con.getOutputStream();
os.write(parent.toString().getBytes("UTF-8"));
os.close();

In my experience it's best to put as much code as you can into well-named modules, and only put as much code as you need to into the actual worksheet objects.
Example: Any code that uses worksheet events like Worksheet_SelectionChange or Worksheet_Calculate.

*ptr = 20; //Dereference that pointer,
// and assign a value to random memory address.
//Depending on external (not inside your program) state
// this will either crash or SILENTLY CORRUPT another
// data structure in your program.
printf("%d", *ptr); //Print contents of same random memory address
// May or may not crash, depending on who owns this address
return 0;
}
Second Program with comments
#include <stdio.h>
int main(){
int *ptr; //Create pointer to random memory address
int q = 50; //Create local variable with contents int 50
ptr = &q; //Update address targeted by above created pointer to point
// to local variable your program properly created
printf("%d", *ptr); //Happily print the contents of said local variable (q)
return 0;
}
The key is you cannot use a pointer until you know it is assigned to an address that you yourself have managed, either by pointing it at another variable you created or to the result of a malloc call.
Using it before is creating code that depends on uninitialized memory which will at best crash but at worst work sometimes, because the random memory address happens to be inside the memory space your program already owns. God help you if it overwrites a data structure you are using elsewhere in your program.
Hope this might be useful to you.

In recent Oracle versions the COST represent the amount of time that the optimiser expects the query to take, expressed in units of the amount of time required for a single block read.
So if a single block read takes 2ms and the cost is expressed as "250", the query could be expected to take 500ms to complete.
The optimiser calculates the cost based on the estimated number of single block and multiblock reads, and the CPU consumption of the plan. the latter can be very useful in minimising the cost by performing certain operations before others to try and avoid high CPU cost operations.
This raises the question of how the optimiser knows how long operations take. recent Oracle versions allow the collections of "system statistics", which are definitely not to be confused with statistics on tables or indexes. The system statistics are measurements of the performance of the hardware, mostly importantly:
These numbers can vary greatly according to the operating environment of the system, and different sets of statistics can be stored for "daytime OLTP" operations and "nighttime batch reporting" operations, and for "end of month reporting" if you wish.
Given these sets of statistics, a given query execution plan can be evaluated for cost in different operating environments, which might promote use of full table scans at some times or index scans at others.
The cost is not perfect, but the optimiser gets better at self-monitoring with every release, and can feedback the actual cost in comparison to the estimated cost in order to make better decisions for the future. this also makes it rather more difficult to predict.
Note that the cost is not necessarily wall clock time, as parallel query operations consume a total amount of time across multiple threads.
In older versions of Oracle the cost of CPU operations was ignored, and the relative costs of single and multiblock reads were effectively fixed according to init parameters.
If you want to do that why not go with a while, for ease of mind? :P No, but seriously I didn't know that and seems kinda nice so thanks, nice to know!
Select cell B2 and click "Freeze Panes" this will freeze Row 1 and Column A.
For future reference, selecting Freeze Panes in Excel will freeze the rows above your selected cell and the columns to the left of your selected cell. For example, to freeze rows 1 and 2 and column A, you could select cell B3 and click Freeze Panes. You could also freeze columns A and B and row 1, by selecting cell C2 and clicking "Freeze Panes".

rev4: A very eloquent comment by user Sammaron has noted that, perhaps, this answer previously confused top-down and bottom-up. While originally this answer (rev3) and other answers said that "bottom-up is memoization" ("assume the subproblems"), it may be the inverse (that is, "top-down" may be "assume the subproblems" and "bottom-up" may be "compose the subproblems"). Previously, I have read on memoization being a different kind of dynamic programming as opposed to a subtype of dynamic programming. I was quoting that viewpoint despite not subscribing to it. I have rewritten this answer to be agnostic of the terminology until proper references can be found in the literature. I have also converted this answer to a community wiki. Please prefer academic sources. List of references: {Web: 1,2} {Literature: 5}
Dynamic programming is all about ordering your computations in a way that avoids recalculating duplicate work. You have a main problem (the root of your tree of subproblems), and subproblems (subtrees). The subproblems typically repeat and overlap.
For example, consider your favorite example of Fibonnaci. This is the full tree of subproblems, if we did a naive recursive call:
TOP of the tree
fib(4)
fib(3)...................... + fib(2)
fib(2)......... + fib(1) fib(1)........... + fib(0)
fib(1) + fib(0) fib(1) fib(1) fib(0)
fib(1) fib(0)
BOTTOM of the tree
(In some other rare problems, this tree could be infinite in some branches, representing non-termination, and thus the bottom of the tree may be infinitely large. Furthermore, in some problems you might not know what the full tree looks like ahead of time. Thus, you might need a strategy/algorithm to decide which subproblems to reveal.)
There are at least two main techniques of dynamic programming which are not mutually exclusive:
Memoization - This is a laissez-faire approach: You assume that you have already computed all subproblems and that you have no idea what the optimal evaluation order is. Typically, you would perform a recursive call (or some iterative equivalent) from the root, and either hope you will get close to the optimal evaluation order, or obtain a proof that you will help you arrive at the optimal evaluation order. You would ensure that the recursive call never recomputes a subproblem because you cache the results, and thus duplicate sub-trees are not recomputed.
fib(100)
, you would just call this, and it would call fib(100)=fib(99)+fib(98)
, which would call fib(99)=fib(98)+fib(97)
, ...etc..., which would call fib(2)=fib(1)+fib(0)=1+0=1
. Then it would finally resolve fib(3)=fib(2)+fib(1)
, but it doesn't need to recalculate fib(2)
, because we cached it.Tabulation - You can also think of dynamic programming as a "table-filling" algorithm (though usually multidimensional, this 'table' may have non-Euclidean geometry in very rare cases*). This is like memoization but more active, and involves one additional step: You must pick, ahead of time, the exact order in which you will do your computations. This should not imply that the order must be static, but that you have much more flexibility than memoization.
fib(2)
,fib(3)
,fib(4)
... caching every value so you can compute the next ones more easily. You can also think of it as filling up a table (another form of caching).(At it's most general, in a "dynamic programming" paradigm, I would say the programmer considers the whole tree, then writes an algorithm that implements a strategy for evaluating subproblems which can optimize whatever properties you want (usually a combination of time-complexity and space-complexity). Your strategy must start somewhere, with some particular subproblem, and perhaps may adapt itself based on the results of those evaluations. In the general sense of "dynamic programming", you might try to cache these subproblems, and more generally, try avoid revisiting subproblems with a subtle distinction perhaps being the case of graphs in various data structures. Very often, these data structures are at their core like arrays or tables. Solutions to subproblems can be thrown away if we don't need them anymore.)
[Previously, this answer made a statement about the top-down vs bottom-up terminology; there are clearly two main approaches called Memoization and Tabulation that may be in bijection with those terms (though not entirely). The general term most people use is still "Dynamic Programming" and some people say "Memoization" to refer to that particular subtype of "Dynamic Programming." This answer declines to say which is top-down and bottom-up until the community can find proper references in academic papers. Ultimately, it is important to understand the distinction rather than the terminology.]
Memoization is very easy to code (you can generally* write a "memoizer" annotation or wrapper function that automatically does it for you), and should be your first line of approach. The downside of tabulation is that you have to come up with an ordering.
*(this is actually only easy if you are writing the function yourself, and/or coding in an impure/non-functional programming language... for example if someone already wrote a precompiled fib
function, it necessarily makes recursive calls to itself, and you can't magically memoize the function without ensuring those recursive calls call your new memoized function (and not the original unmemoized function))
Note that both top-down and bottom-up can be implemented with recursion or iterative table-filling, though it may not be natural.
With memoization, if the tree is very deep (e.g. fib(10^6)
), you will run out of stack space, because each delayed computation must be put on the stack, and you will have 10^6 of them.
Either approach may not be time-optimal if the order you happen (or try to) visit subproblems is not optimal, specifically if there is more than one way to calculate a subproblem (normally caching would resolve this, but it's theoretically possible that caching might not in some exotic cases). Memoization will usually add on your time-complexity to your space-complexity (e.g. with tabulation you have more liberty to throw away calculations, like using tabulation with Fib lets you use O(1) space, but memoization with Fib uses O(N) stack space).
If you are also doing a extremely complicated problems, you might have no choice but to do tabulation (or at least take a more active role in steering the memoization where you want it to go). Also if you are in a situation where optimization is absolutely critical and you must optimize, tabulation will allow you to do optimizations which memoization would not otherwise let you do in a sane way. In my humble opinion, in normal software engineering, neither of these two cases ever come up, so I would just use memoization ("a function which caches its answers") unless something (such as stack space) makes tabulation necessary... though technically to avoid a stack blowout you can 1) increase the stack size limit in languages which allow it, or 2) eat a constant factor of extra work to virtualize your stack (ick), or 3) program in continuation-passing style, which in effect also virtualizes your stack (not sure the complexity of this, but basically you will effectively take the deferred call chain from the stack of size N and de-facto stick it in N successively nested thunk functions... though in some languages without tail-call optimization you may have to trampoline things to avoid a stack blowout).
Here we list examples of particular interest, that are not just general DP problems, but interestingly distinguish memoization and tabulation. For example, one formulation might be much easier than the other, or there may be an optimization which basically requires tabulation:
<script type="text/javascript" language="javascript">
function createDiv()
{
var divTag = document.createElement("div");
divTag.innerHTML = "Div tag created using Javascript DOM dynamically";
document.body.appendChild(divTag);
}
</script>
You can add .a file in the linking command:
gcc yourfiles /path/to/library/libLIBRARY.a
But this is not talking with gcc driver, but with ld
linker as options like -Wl,anything
are.
When you tell gcc or ld -Ldir -lLIBRARY
, linker will check both static and dynamic versions of library (you can see a process with -Wl,--verbose
). To change order of library types checked you can use -Wl,-Bstatic
and -Wl,-Bdynamic
. Here is a man page of gnu LD: http://linux.die.net/man/1/ld
To link your program with lib1, lib3 dynamically and lib2 statically, use such gcc call:
gcc program.o -llib1 -Wl,-Bstatic -llib2 -Wl,-Bdynamic -llib3
Assuming that default setting of ld is to use dynamic libraries (it is on Linux).
I has encountered the same error, and I found that it resulted from different modules contained the same classes from different packages.
e.g. One used androidx package, and the other used pre-androidx
I solved it by migrating the pre-androidx module to androidx using built-in feature of Android Studio: "Refactor --> Migrate to Androidx..." without excluding anything.
For your situation, you may check if you have any dependency mismatches among modules.
This can be done by using the unbind function.
$('#myimage').unbind('click');
You can add multiple event handlers to the same object and event in jquery. This means adding a new one doesn't replace the old ones.
There are several strategies for changing event handlers, such as event namespaces. There are some pages about this in the online docs.
Look at this question (that's how I learned of unbind). There is some useful description of these strategies in the answers.
Here's a rather simple solution:
In the controller we return our errors like this:
if (!ModelState.IsValid)
{
return Json(new { success = false, errors = ModelState.Values.SelectMany(x => x.Errors).Select(x => x.ErrorMessage).ToList() }, JsonRequestBehavior.AllowGet);
}
Here's some of the client script:
function displayValidationErrors(errors)
{
var $ul = $('div.validation-summary-valid.text-danger > ul');
$ul.empty();
$.each(errors, function (idx, errorMessage) {
$ul.append('<li>' + errorMessage + '</li>');
});
}
That's how we handle it via ajax:
$.ajax({
cache: false,
async: true,
type: "POST",
url: form.attr('action'),
data: form.serialize(),
success: function (data) {
var isSuccessful = (data['success']);
if (isSuccessful) {
$('#partial-container-steps').html(data['view']);
initializePage();
}
else {
var errors = data['errors'];
displayValidationErrors(errors);
}
}
});
Also, I render partial views via ajax in the following way:
var view = this.RenderRazorViewToString(partialUrl, viewModel);
return Json(new { success = true, view }, JsonRequestBehavior.AllowGet);
RenderRazorViewToString method:
public string RenderRazorViewToString(string viewName, object model)
{
ViewData.Model = model;
using (var sw = new StringWriter())
{
var viewResult = ViewEngines.Engines.FindPartialView(ControllerContext,
viewName);
var viewContext = new ViewContext(ControllerContext, viewResult.View,
ViewData, TempData, sw);
viewResult.View.Render(viewContext, sw);
viewResult.ViewEngine.ReleaseView(ControllerContext, viewResult.View);
return sw.GetStringBuilder().ToString();
}
}
This is an example for converting a CSV file in Python 3:
try:
inputReader = csv.reader(open(argv[1], encoding='ISO-8859-1'), delimiter=',',quotechar='"')
except IOError:
pass
try this.. the below one copy the entire structure of the existing table but not the data.
create table AT_QUOTE_CART as select * from QUOTE_CART where 0=1 ;
if you want to copy the data then use the below one:
create table AT_QUOTE_CART as select * from QUOTE_CART ;
What about System.Web.Helpers.Json.Encode(...) (see http://msdn.microsoft.com/en-us/library/system.web.helpers.json.encode(v=vs.111).aspx)?
It's simple. Just use
$(selector).parents().eq(0);
where 0 is the parent level (0 is parent, 1 is parent's parent etc)
Procedures in a Module start being useful and generic when you pass in arguments.
For example:
Public Function DoSomethingElse(strMessage As String)
MsgBox strMessage
End Function
Can now display any message that is passed in with the string variable called strMessage.
