I have a Exe file that refers to multiple dlls, the dll is user control,
Ex: Main.exe A.dll B.dll C.dll
When the program is executed, what is the execution order of the construction formula and Load( ) of each file? and how to set it?
For example, I want the following sequence, how to achieve?
B( ) => A( ) => C( ) => Main( )
B_Load( ) => A_Load( ) => C_Load( ) => Main_Load( )

I could not able to find in the documentation on how to get only updated records/rows from Google Sheets API.
Is there a way, that I can get a timestamp of each record when it was last modified?
any guidance or any links that would solve this issue.
Thanks!
You cannot do this directly with Sheets API. You can keep track of the changes in a file using Drive API, though, but I don't think this is what you want to do.
I'd propose using an onEdit trigger using Apps Script. Every time the spreadsheet is modified, you could retrieve the data of the edited range and store it somewhere, as well as the current date.
It could be something on the following lines:
function onEdit(e) {
var timestamp = new Date();
var range = e.range;
var editedRow = range.getRow();
// Store timestamp and editedRow index somewhere you can retrieve it later (it could be in the spreadsheet itself)
}
Update:
You can create the trigger remotely using Apps Script API. First you should create a project bound to your spreadsheet and then add the corresponding code by calling projects.updateContent (you should add two files, the script itself, which contains the onEdit trigger, and the manifest file). Just beware that you can only use simple triggers with this API, not installable ones. But in your situation, that's more than enough.
I hope this is of any help.

Does documentation exist on how to change code written in NEST 1.x to 2.x?
I've looked at these sites and they're incomplete:
https://github.com/elastic/elasticsearch-net/blob/master/docs/2.0-breaking-changes/nest-breaking-changes.md
https://github.com/elastic/elasticsearch-net
https://www.elastic.co/blog/ga-release-of-nest-2-0-our-dot-net-client-for-elasticsearch
For example I'd like to know how to replace the following:
1)
given ISearchResponse<T> searchResults = ...
How to do:
searchResults.ConnectionStatus
searchResults.RequestInformation.Request
2)
client.Get<T>(s => s.Id(id));
3)
Given QueryContainer query
new SearchDescriptor<T>()
.From(from)
.Size(pageSize)
.Query(query); //this dosen't work anymore
4)
MatchQuery doesn't accept fuziness as double and type parameters as string as it used to
5) QueryDescriptor seems gone gasp
6) client.Update is busted
var result = client.Update<CustomerProfile>(request => request
.Id(customer.CustomerId)
.Doc(customer)
.Refresh()
);
7) client.Get is busted in a similar way to client.Update
8) In Mappings the following setup doesn't work anymore
CreateIndexDescriptor cid = ...
cid.NumberOfReplicas(numReplicas)
.NumberOfShards(numShards)
.Settings(s => s
.Add("merge.policy.merge_factor", "10")
.Add("search.slowlog.threshold.fetch.warn", "1s")
)
.Analysis(a => a.TokenFilters etc etc
EDIT
9) Date Ranges:
startDate and endDate are DateTime type
var qd = new QueryContainerDescriptor<EsActivity>();
QueryContainer qc = qd.Range(r =>
r.Field("esactivity.timestamp")
.GreaterThanOrEquals(DateMath.Anchored(startDate))
.LessThanOrEquals(DateMath.Anchored(endDate))
);
.GreaterThanOrEquals expects a double parameter but on the documentation page it takes DateMath.Anchored(startDate)
10) Highlighting:
highlightFields: List<string>
Action<HighlightFieldDescriptor<T>> [] tmp = highlightFields.Select(field =>
new Action<HighlightFieldDescriptor<T>>(
highlighter => highlighter.Field(field)
)
).ToArray();
sd:SearchDescriptor<..>..
sd.Highlight(h => h
.PreTags(preTag)
.PostTags(postTag)
.OnFields(tmp)
);
I see I can replace OnFields(tmp) with .Fields(f=>f.OnAll()) but I'd still like to specify the fields myself in some way.
And how come there is a HighlightQuery option available since we already apply highlighting on a query object.. now there are 2 query calls.
I've converted the highlighting above to
var tmp = highlightFields.Select(field =>
Tuple.Create<Field, IHighlightField>(
Field.Create(field),
new HighlightField()
)
).ToDictionary(x => x.Item1, x => x.Item2);
sd.Highlight(h => new Highlight
{
PreTags = new[] { preTag },
PostTags = new[] { postTag },
Fields = tmp
}
);
1) searchResults.ApiCall replaces searchResults .ConnectionStatus.
You can get the request bytes with searchResults.ApiCall.RequestBodyInBytes and you will also need to set .DisableDirectStreaming() on ConnectionSettings in order to capture the bytes as the request is written to the request stream directly by default.
2) Use client.Get<T>(id) - The first parameter is a DocumentPath<T> type.
3) To pass a QueryContainer to a Fluent API descriptor, just return it from the Func<QueryContainerDescriptor<T>, QueryContainer>
new SearchDescriptor<T>()
.From(from)
.Size(pageSize)
.Query(_ => query);
4) match query fuzziness as a double mapped to a formula to calculate edit distance in Elasticsearch 1.x. Since this was removed in Elasticsearch 2.x, it is also gone from NEST. You can set fuzziness edit distance with
client.Search<Document>(s => s
.Query(q => q
.Match(m => m
.Query("this is my query")
.Fuzziness(Fuzziness.EditDistance(3))
)
)
);
Not sure what you're referring to with type, but I think you're referring to document type? If that's the case, document type takes a Types type which string implicitly converts to
client.Search<Document>(s => s
.Type("other-type")
.MatchAll()
);
5) QueryDescriptor<T> was renamed to QueryContainerDescriptor<T> to better reflect the fact that it's a descriptor for building a QueryContainer
6) Update API works
// specifying id
client.Update<Document>("document-id", u => u
.Doc(document)
.Refresh()
);
Since the first parameter is a DocumentPath<T>, the document instance (if you have it) can be passed as the first parameter
client.Update<Document>(document, u => u
.Doc(document)
.Refresh()
);
where index, type and id will be inferred from the document instance
7) See above
8) Create index settings have been revised to reflect the level at which the settings appear in the REST API json call
client.CreateIndex("index-name", c => c
.Settings(s => s
.NumberOfShards(2)
.NumberOfReplicas(2)
.SlowLog(sl => sl
.Search(sls => sls
.Fetch(slsf => slsf
.ThresholdWarn("1s")
)
)
)
.Analysis(a => a) // etc...
)
);
You can also use strings for settings if you prefer, although the fluent API will ensure the correct setting values are sent e.g. "search.slowlog.threshold.fetch.warn" is now "index.search.slowlog.threshold.fetch.warn"
client.CreateIndex("index-name", c => c
.Settings(s => s
.NumberOfShards(2)
.NumberOfReplicas(2)
.Setting("index.search.slowlog.threshold.fetch.warn", "1s")
.Analysis(a => a) // etc...
)
);
merge.policy.merge_factor is removed in Elasticsearch 2.0
Is it possible when using FAL, to set the upload destination folder directly in the TCA column? My configuration looks like this at the moment:
'images_outdoor' => Array (
'exclude' => 1,
'label' => 'Outdoor: ',
'config' => \TYPO3\CMS\Core\Utility\ExtensionManagementUtility::getFileFieldTCAConfig('images_outdoor', Array (
'appearance' => Array (
'createNewRelationLinkTitle' => 'LLL:EXT:cms/locallang_ttc.xlf:images.addFileReference'
),
'minitems' => 1,
'maxitems' => 6,
), $GLOBALS['TYPO3_CONF_VARS']['GFX']['imagefile_ext']),
),
I have such columns in different TCAs and want their images to be saved in different folders. So a standard folder setting doesn't work here.
I know this one is old but here is a answer.
There are no supported way for TYPO3 6.2, but in the new TYPO3 7.6 LTS it should be possible to register a hook in your ext_localconf.php file, add this:
$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['t3lib/class.t3lib_userauthgroup.php']['getDefaultUploadFolder'][] = 'VendorName\ExtensionName\Hooks\BackendUserAuthentication->getDefaultUploadFolder'
Create the file Classes/Hooks/BackendUserAuthentication.php and write something like this:
<?php
namespace VendorName\ExtensionName\Hooks;
classe BackendUserAuthentication {
public function getDefaultUploadFolder(Array $params, \TYPO3\CMS\Core\Authentication\BackendUserAuthentication $backendUserAuthentication) {
// Do what you wants here and return a object of \TYPO3\CMS\Core\Resource\Folder
}
}
The params array will contain this:
$_params = array(
'uploadFolder' => $uploadFolder, // The current \TYPO3\CMS\Core\Resource\Folder object, properly 1:/user_upload/
'pid' => $pid, // Page id
'table' => $table, // The table name
'field' => $field, // The field name
);
Now use the table and field name to change the upload folder - good look :)
I am new in CakePHP, but I use Rails. I would like to do something like this in CakePHP:
class Manager < ActiveRecord::Base
has_many :employees
end
and ask then the object like this:
m = Manager.find(1)
# Sends SQL query SELECT COUNT * FROM EMPLOYEES WHERE MANAGER_ID = 1
count = m.employees.count
# Sends SQL query SELECT * FROM EMPLOYEES WHERE MANAGER_ID = 1
m.employees.each do |e|
puts e.name
end
I have this code in CakePHP...
class Manager extends AppModel {
public $hasMany = array(
'Employee' => array(
'className' => 'Employee',
'order' => 'Employee.created DESC'
)
);
}
class Employee extends AppModel {
public $belongsTo = 'Manager';
}
How can I do implementation of these (above) functionality (which is in RoR easy made by its ORM) in CakePHP?
Thanks for help...

Your question boils down to "How can I retrieve the Manager with id=1 and find his Employees.
In CakePHP you would issue the following find query to retrieve the desired manager entry:
$manager = $this->Manager->findById(1);
// or
$manager = $this->Manager->find('first', array(
'conditions' => array(
'Manager.id' => 1
)
);
The above find calls fetch the manager with id=1 from the database and because you set up the relationship Manager hasMany Employee, the result will also contain all employees for the manager ordered by Employee.created DESC.
The resultset would look something like this:
Array
(
[Manager] => Array
(
[id] => 1
[field1] => value1
)
[Employee] => Array
(
[0] => Array
(
[id] => 2
[manager_id] => 1
[name] => Bar
)
[1] => Array
(
[id] => 1
[manager_id] => 1
[name] => Foo
)
)
)
As you can see, CakePHP uses an array format for returned results and not an object as in Ruby on Rails. Therefore you have to access your related data within the resulting array.
Another important difference between CakePHP and Ruby on Rails(RoR) is, that in CakePHP the queries to the db are executed the moment you call them, whereas in RoR they are lazily executed the moment you try to access the results.
To complement your RoR example for accessing employees here is the CakePHP version:
$employee_count = count($manager['Employee']);
foreach ($manager['Employee'] as $e) {
echo $e['name'];
}
I hope this clears up some confusion.
I think you are looking for the containable behavior of CakePHP.
It is important to attach the containable behavior to your model(s), otherwise it won't work.
Can you send more parameters than needed to a prepared statement using PDO with no undesired side effects?
That mights seem like a strange question but I ask because I have 4 queries in a row which all use similar and different parameters. The relevant parts of the queries:
1st (select, different table to others):
WHERE threadID = :tid
2nd (select):
WHERE user_ID = :u_ID AND thread_ID = :tid
3rd (update if 2nd was successful):
SET time = :current_time WHERE user_ID = :u_ID AND thread_ID = :tid
4th (insert if 2nd was unsuccessful):
VALUES (:u_ID, :tid, :current_time)
Can I declare one array with the three parameters at the beginning and use it for all 4 queries?
To sort out any confusion, the queries would be executed seperately. It is the parameters variable being reused and so that would mean some queries would receive parameters they don't need. So something like:
$parameters = array(':tid' => $tid, ':u_ID' => $u_ID, ':current_time' => $time);
$1st = $db->prepare($query1);
$1st->execute($parameters);
$2nd = $db->prepare($query2);
$2nd->execute($parameters);
$3rd = $db->prepare($query3);
$3rd->execute($parameters);
$4th = $db->prepare($query4);
$4th->execute($parameters);
If I can, should I? Will this slow down or cause security flaws to my database or scripts?
If I can make this question a bit clearer, please ask.
Thank you!
Perhaps the documentation has been updated since this question was first asked, but now it is quite clearly stated "No"
You cannot bind more values than specified; if more keys exist in input_parameters than in the SQL specified in the PDO::prepare(), then the statement will fail and an error is emitted.
These answers should be useful in filtering out the extra parameters.
I know this is already answered and it's only asking about whether you can send extra params, but I thought people might arrive at this question, and want to know how to get around this limitation. Here's the solution I use:
$parameters = array('tid' => $tid, 'u_ID' => $u_ID, 'current_time' => $time);
$1st = $db->prepare($query1);
$1st->execute(array_intersect_key($parameters, array_flip(array('tid'))));
$2nd = $db->prepare($query2);
$2nd->execute(array_intersect_key($parameters, array_flip(array('u_ID', 'tid'))));
$3rd = $db->prepare($query3);
$3rd->execute(array_intersect_key($parameters, array_flip(array('u_ID', 'tid', 'current_time'))));
$4th = $db->prepare($query4);
$4th->execute(array_intersect_key($parameters, array_flip(array('u_ID', 'tid', 'current_time'))));
That array_interset_key and array_flip maneuver could be extracted to its own function, like:
function filter_fields($params,$field_names) {
return array_intersect_key($params, array_flip($field_names))
}
I just haven't got around to it yet.
The function flips your array of key names, so you have an array with no values, but the right keys. Then intersect filters the first array so you only have the keys that are in both arrays (in this case, only the ones in your array_flipped array). But you get the values for the original array (not the empties). So you make one array of parameters, but specify which params are actually sent to PDO.
So, with the function, you'd do:
$parameters = array('tid' => $tid, 'u_ID' => $u_ID, 'current_time' => $time);
$1st = $db->prepare($query1);
$1st->execute(filter_fields($parameters, array('tid')));
$2nd = $db->prepare($query2);
$2nd->execute(filter_fields($parameters, array('u_ID', 'tid')));
$3rd = $db->prepare($query3);
$3rd->execute(filter_fields($parameters, array('u_ID', 'tid', 'current_time')));
$4th = $db->prepare($query4);
$4th->execute(filter_fields($parameters, array('u_ID', 'tid', 'current_time')));
If you have PHP 5.4, you can use the square bracket array syntax, to make it even cooler:
$parameters = array('tid' => $tid, 'u_ID' => $u_ID, 'current_time' => $time);
$1st = $db->prepare($query1);
$1st->execute(filter_fields($parameters, ['tid']));
$2nd = $db->prepare($query2);
$2nd->execute(filter_fields($parameters, ['u_ID', 'tid']));
$3rd = $db->prepare($query3);
$3rd->execute(filter_fields($parameters, ['u_ID', 'tid', 'current_time']));
$4th = $db->prepare($query4);
$4th->execute(filter_fields($parameters, ['u_ID', 'tid', 'current_time']));
I got a chance to test my question, and the answer is you cannot send more parameters than the query uses. You get the following error:
PDOException Object

)
)
)
)
[previous:Exception:private] =>
[errorInfo] => Array
(

[1] => 0
)
)
I don't know a huge amount about PDO, hence my question, but I think that because :current_time is sent but not used and the error message is "Invalid parameter number: parameter was not defined" you cannot send extra parameters which are not used.
Additionally the error code HY093 is generated. Now I can't seem to find any documentation explaining PDO codes anywhere, however I came across the following two links specifically about HY093:
What is PDO Error HY093
SQLSTATE[HY093]
It seems HY093 is generated when you incorrectly bind parameters. This must be happening here because I am binding too many parameters.
executing different type of multiple queries with one execute leads to problems. you can run multiple selects or multiple updates with one execute. For this case to create different prepared statements objects and pass the the parameters accordingly.
// for WHERE threadID = :tid
$st1 = $db->prepare($sql);
$st1->bindParam(':tid', $tid);
$st1->execute();
or
$st1->execute(array(':tid'=>$tid);
// for WHERE user_ID = :u_ID AND thread_ID = :tid
$st2 = $db->prepare($sql);
$st2->bindParam(':u_ID', $u_ID);
$st2->bindParam(':tid', $tid);
$st2->execute();
or
$st2->execute(array(':tid'=>$tid, ':u_ID' => $u_ID);
// for SET time = :current_time WHERE user_ID = :u_ID AND thread_ID = :tid
$st3 = $db->prepare($sql);
$st3->bindParam(':u_ID', $u_ID);
$st3->bindParam(':tid', $tid);
$st3->bindParam(':current_time', $current_time);
