I'm calling a stored proc in a foreach loop and would like to change the value of one of the parameters on each iteration. Currently, there doesn't seem to be any way to access the parameters once they've been added to DynamicParameters although from reading the source, I can see that DynamicParameters does keep an internal Dictionary. Any reason why this isn't public or if there's another way to get at the ParamInfos to change values?
Update
What I have currently:
foreach ( var fooID in fooIDs )
{
var dynamicParameters = new DynamicParameters();
dynamicParameters.Add( ParameterNames.BarID, barID );
dynamicParameters.Add( ParameterNames.FooID, fooID);
connection.Execute( ProcNames.MyProc, dynamicParameters, commandType:CommandType.StoredProcedure );
}
Re-Add the parameter.
// Call Add() with new values.
dynamicParameters.Add(ParameterNames.BarID, differentBarID);
There is no real reason DynamicParameters is so secret about what it does, the ParamInfo class could be exposed and I would be happy to provide proper iteration/modification properties and/or methods. If you feel like you would like to pitch in, please submit a patch.
In the mean time you can simply implement IDynamicParameters which is the trivial interface we use to dispatch this to the underlying command, in your app. You can use DynamicParameters as a starting point.

I have created a new index that is populated using an indexer. The indexer's datasource is a SQL view that has a Timestamp column of type datetime. Since we don't want a full reindexing each time the indexer runs, this column should be used to determine which data have changed since the last indexer run.
According to the documentation we need to create or update the datasource by setting the HighWatermarkColumnName and ODataType to the DataChangeDetectionPolicy object. The example in the documentation uses the REST API and there is also way to do it using the azure search portal directly.
However I want to do it using .netsdk and so far I haven't been able to do so. I am using Azure.Search.Documents(11.2.0 - beta.2). Here is the part of the code I use to create the datasource:
SearchIndexerDataSourceConnection CreateIndexerDataSource()
{
var ds = new SearchIndexerDataSourceConnection(DATASOURCE,
SearchIndexerDataSourceType.AzureSql,
this._datasourceConStringMaxEvents,
new SearchIndexerDataContainer(SQLVIEW));
//ds.DataChangeDetectionPolicy = new DataChangeDetectionPolicy();
return ds;
}
The commented code is what I tried to do to initialize the DataChangeDetectionPolicy but there is no ctor exposed. Am I missing something?
Thanks in advance.
Instead of using DataChangeDetectionPolicy, you will need to use HighWaterMarkChangeDetectionPolicy which is derived from DataChangeDetectionPolicy.
So your code would be something like:
ds.DataChangeDetectionPolicy = new HighWaterMarkChangeDetectionPolicy("Timestamp");
global with sharing class test1 {
global Map<SObjectField, SObject> ConvertMap(List<SObject> listToConvert){
List<SObject> listToConvert = new List<SObject>;
Map<SObjectField, SObject> mapTest = new Map<SObjectField, SObject>;
mapTest.putAll(listToConvert);
return mapTest;
}
I've written this code, but it doesn't respect the request 'cause I can't put SObjectField as method parameter since the Map won't recognize the variable.
Does anyone have suggestions on how to do it?
Thank you in advance.
Do you really need SobjectField as map keys? the special class? If you're fine with strings as keys then there's a builtin, getPopulatedFieldsAsMap()
If you absolutely need SobjectField (I don't even know if it's serializable and can be passed to integrations, LWC etc)... You'd have to loop and marry the results to something like
Schema.describeSObjects(new List<String>{'Account'})[0].fields.getMap()
As my CakePHP 2.4 app gets bigger, I'm noticing I'm passing a lot of arrays around in the model layer. Cake has kinda led me down this path because it returns arrays, not objects, from it's find calls. But more and more, it feels like terrible practice.
For example, in my Job model, I've got a method like this:
public function durationInSeconds($job) {
return $job['Job']['estimated_hours'] * 3600; // convert to seconds
}
Where as I imagine that using active record patter, it should look more like this:
public function durationInSeconds() {
return $this->data['Job']['estimated_hours'] * 3600; // convert to seconds
}
(ie, take no parameter, and assume the current instance represents the Job you want to work with)
Is that second way better?
And if so, how do I use it when, for example, I'm looping through the results of a find('all') call? Cake returns an array - do I loop through that array and do a read for every single row? (seems a waste to re-fetch the info from the database)
Or should I implement a kind of setActiveRecord method that emulates read, like this:
function setActiveRecord($row){
$this->id = $row['Job']['id'];
$this->dtaa = $row;
}
Or is there a better way?
EDIT: The durationInSeconds method was just a simplest possible example. I know for that particular case, I could use virtual fields. But in other cases I've got methods that are somewhat complex, where virtual fields won't do.
The best solution depends on the issue you need to solve. But if you have to make a call to a function for each result row, perhaps it is necessary to redesign the query taking all the necessary data.
In this case that you have shown, you can use simply a virtual Field on Job model:
$this->virtualFields = array(
'duration_in_seconds' => 'Job.estimated_hours * 3600',
):
..and/or you can use a method like this:
public function durationInSeconds($id = null) {
if (!empty($id)) {
$this->id = $id;
}
return $this->field('estimated_hours') * 3600; // convert to seconds
}
I would like to achieve dictionary like data pattern that can be accessed from the
java script. Something like this:
pseudo Code:
for all records:
{
rec = //Get the Record
rec["Name"]
rec["Address"]
}
I am trying to achieve with CefV8Accessor, but i am not getting near to the solution.
Kindly provide few links for the reference, as i see the documentation is very less from chromium embedded.
If I understand correctly, you're trying to create a JS "dictionary" object for CEF using C++. If so, here's a code snippet that does that:
CefRefPtr<CefV8Value> GetDictionary(__in const wstring& sName, __in const wstring& sAddress)
{
CefRefPtr<CefV8Value> objectJS = CefV8Value::CreateObject(NULL);
objectJS->SetValue(L"Name", sName, V8_PROPERTY_ATTRIBUTE_NONE);
objectJS->SetValue(L"Address", sAddress, V8_PROPERTY_ATTRIBUTE_NONE);
return objectJS;
}
The CefV8Accessor can also be used for that matter, but that's only if you want specific control over the set & get methods, to create a new type of object.
In that case you should create a class that inherits CefV8Accessor, implement the Set and Get methods (in a similar way to what appears in the code above), and pass it to the CreateObject method. The return value would be an instance of that new type of object.
I strongly suggest to browse through this link, if you haven't already.
I've been asked to set up a process which monitors the active directory, specifically certain accounts, to check that they are not locked so that should this happen, the support team can get an early warning.
I've found some code to get me started which basically sets up requests and adds them to a notification queue. This event is then assigned to a change event and has an ObjectChangedEventArgs object passed to it.
Currently, it iterates through the attributes and writes them to a text file, as so:
private static void NotifierObjectChanged(object sender,
ObjectChangedEventArgs e)
{
if (e.ResultEntry.Attributes.AttributeNames == null)
{
return;
}
// write the data for the user to a text file...
using (var file = new StreamWriter(#"C:\Temp\UserDataLog.txt", true))
{
file.WriteLine("{0} {1}", DateTime.UtcNow.ToShortDateString(), DateTime.UtcNow.ToShortTimeString());
foreach (string attrib in e.ResultEntry.Attributes.AttributeNames)
{
foreach (object item in e.ResultEntry.Attributes[attrib].GetValues(typeof(string)))
{
file.WriteLine("{0}: {1}", attrib, item);
}
}
}
}
What I'd like is to check the object and if a specific field, such as name, is a specific value, then check to see if the IsAccountLocked attribute is True, otherwise skip the record and wait until the next notification comes in. I'm struggling how to access specific attributes of the ResultEntry without having to iterate through them all.
I hope this makes sense - please ask if I can provide any additional information.
Thanks

This could get gnarly depending upon your exact business requirements. If you want to talk in more detail ping me offline and I'm happy to help over email/phone/IM.
So the first thing I'd note is that depending upon what the query looks like before this, this could be quite expensive or error prone (ie missing results). This worries me somewhat as most sample code out there gets this wrong. :) How are you getting things that have changed? While this sounds simple, this is actually a somewhat tricky question in directory land, given the semantics supported by AD and the fact that it is a multi-master system where writes happen all over the place (and replicate in after the fact).
Other variables would be things like how often you're going to run this, how large the data set could be in AD, and so on.
AD has some APIs built to help you here (the big one that comes to mind is called DirSync) but this can be somewhat complicated if you haven't used it before. This is where the "ping me offline" part comes in.
To your exact question, I'm assuming your result is actually a SearchResultEntry (if not I can revise, tell me what you have in hand). If that is the case then you'll find an Attributes field hanging off of that guy, and from there there is AttributeNames and Values. I think you'll see how it works from there if you have Values in hand, for example:
foreach (var attr in sre.Attributes.Values)
{
var da = (DirectoryAttribute)attr;
Console.WriteLine(da.Name);
foreach (var val in da.GetValues(typeof(byte[])))
{
// Handle a byte[] val ...
}
}
As I said, if you have something other than a SearchResultEntry in hand, let us know and I can revise the code sample.
