I am trying to get the output of a powershell command into an array, but it seems not to work. In fact I want to address the output with a row and a column index.
e.g.
$a=Get-Service
With output (part)
Status Name DisplayName
------ ---- -----------
Stopped AeLookupSvc Application Experience
Stopped ALG Application Layer Gateway Service
Stopped AppIDSvc Application Identity
Running Appinfo Application Information
Stopped AppMgmt Application Management
I want to address for the second line the DisplayName, e.g.
$a[2][2]
And it should give then
Application Layer Gateway Service
But this does not seem to work.
Can anybody help?
This type of question makes me think that you're probably coming from a Unix background, and are accustomed to having to deal with indicies and column index, that sort of thing.
Fundamentally, PowerShell is an object-oriented scripting language. You simply don't need to do what you're asking about here.
For instance, if you want to capture the results, then grab a property for one of the objects, here's how that's done.
First, capture the output.
$a=Get-Service
Now, you want a particular property of a particular entity. To get that, index into the object you want.
>$a[2]
Status Name DisplayName
------ ---- -----------
Stopped AJRouter AllJoyn Router Service
To select the .DisplayName, all you have to do is append that to the end of your previous command.
> $a[2].DisplayName
AllJoyn Router Service
If you want to select multiple values, you could use this approach instead.
#Select multiple values from one entity
$a[2] | select DisplayName, Status
>DisplayName Status
----------- ------
Application Layer Gateway Service Stopped
#Select multiple values from each in the array
$a | select DisplayName, Status
>DisplayName Status
----------- ------
Adobe Acrobat Update Service Running
AllJoyn Router Service Stopped
Application Layer Gateway Service Stopped
Application Identity Stopped
This is not possible without a mapping from property names to array indices. Note that what you see in the output is just a partial list of properties (defined in an XML file somewhere). So there isn't even an easy way to convert those to array indices.
However, I also don't quite understand your need here. You can get the second service with $a[1], as expected. And then you can get its DisplayName property value with $a[1].DisplayName. PowerShell uses objects throughout. There is simply no need to fall back to text parsing or cryptic column indices just to get your data. There's an easier way.
The output from Get-Service that you see in the Console may look like an array (as it is formatted as a table when sent to the Console), but it is actually an 'System.ServiceProcess.ServiceController' object.
Rather than using row and column designations, you need to use the name of the property to retrieve it, so for your example:
$a[2].DisplayName will return Application Layer Gateway Service

I have database of Workspaces with members and some other data. For each workspace there is a members Map, where key is the UserId and value is the email
It is structured like this:
\Workspace01
--- name:
--- color:
--- members:
------ userid: "email#email.com"
I am trying to query workspaces where the current user is a members.
In Security Rules for instance, I can try something like
allow read if uid in resource.members.keys()
and it works fine (I think). It allows read, etc.
However, if I try to query the same thing, for instance in kotlin/android, it gives a permission error:
collection.whereArrayContains("members.keys", uid )
I have also tried FieldPath.of(), or whereNotEqual("members[uid]", null), still the same thing.
I also tried using emails as keys and uid as values... Obviously no difference
There also was a suggestion of using orderBy("memebers.uid"). That also gives a "bad permission". However, this orderBy query works just fine in the Firebase console
I am completely out of ideas.
Help?
You say that the members field is a map, so it makes sense that you can't query it with whereArrayContains.
If you want to check if the uid subfield has a specific value, that'd be:
collection.whereEqualTo("members.theUidValue", "theEmailValue")
I'm not entirely sure that your security rules will allow this, so I'd start with more relaxed rules to first see if the query works.
If you want to simply check whether the UID exists, that isn't possible on a map structure. To allow that, add an additional array field with just the UID values from the map (e.g. memberUIDs), and then query with whereArrayContains on that.
I could need some help with a Anylogic Model.
Model (short): Manufacturing scenario with orders move in a individual route. The workplaces (WP) are dynamical created by simulation start. Their names, quantity and other parameters are stored in a database (excel Import). Also the orders are created according to an import. The Agent population "order" has a collection routing which contains the Workplaces it has to stop in the specific order.
Target: I want a moveTo block in main which finds the next destination of the agent order.
Problem and solution paths:
I set the destination Type to agent and in the Agent field I typed a function agent.getDestination(). This function is in order which returns the next entry of the collection WP destinationName = routing.get(i). With this I get a Datatype error (while run not compiling). I quess it's because the database does not save the entrys as WP Type but only String.
Is there a possiblity to create a collection with agents from an Excel?
After this I tried to use the same getDestination as String an so find via findFirst the WP matching the returned name and return it as WP. WP targetWP = findFirst(wps, w->w.name == destinationName);
Of corse wps (the population of Workplaces) couldn't be found.
How can I search the population?
Maybe with an Agentlink?
I think it is not that difficult but can't find an answer or a solution. As you can tell I'm a beginner... Hope the description is good an someone can help me or give me a hint :)
Thanks
Is there a possiblity to create a collection with agents from an Excel?
Not directly using the collection's properties and, as you've seen, you can't have database (DB) column types which are agent types.1
But this is relatively simple to do directly via Java code (and you can use the Insert Database Query wizard to construct the skeleton code for you).
After this I tried to use the same getDestination as String an so find via findFirst the WP matching the returned name and return it as WP
Yes, this is one approach. If your order details are in Excel/the database, they are presumably referring to workplaces via some String ID (which will be a parameter of the workplace agents you've created from a separate Excel worksheet/database table). You need to use the Java equals method to compare strings though, not == (which is for comparing numbers or whether two objects are the same object).
I want a moveTo block in main which finds the next destination of the agent order
So the general overall solution is
Create a population of Workplace agents (let's say called workplaces in Main) from the DB, each with a String parameter id or similar mapped from a DB column.
Create a population of Order agents (let's say called orders in Main) from the DB and then, in their on-startup action, set up their collection of workplace IDs (type ArrayList, element class String; let's say called workplaceIDsList) using data from another DB table.
Order probably also needs a working variable storing the next index in the list that it needs to go to (so let's say an int variable nextWorkplaceIndex which starts at 0).
Write a function in Main called getWorkplaceByID that has a single String argument id and returns a Workplace. This gets the workplace from the population that matches the ID; a one-line way similar to yours is findFirst(workplaces, w -> w.id.equals(id)).
The MoveTo block (which I presume is in Main) needs to move the Order to an agent defined by getWorkplaceByID(agent.workplaceIDsList.get(nextWorkplaceIndex++)). (The ++ bit increments the index after evaluating the expression so it is ready for the next workplace to go to.)
For populating the collection, you'd have two tables, something like the below (assuming using strings as IDs for workplaces and orders):
orders table: columns for parameters of your orders (including some String id column) other than the workplace-list. (Create one Order agent per row.)
order_workplaces table: columns order_id, sequence_num and workplace_id (so with multiple rows specifying the sequence of workplace IDs for an order ID).
In the On startup action of Order, set up the skeleton query code via the Insert Database Query wizard as below (where we want to loop through all rows for this order's ID and do something --- we'll change the skeleton code to add entries to the collection instead of just printing stuff via traceln like the skeleton code does).
Then we edit the skeleton code to look like the below. (Note we add an orderBy clause to the initial query so we ensure we get the rows in ascending sequence number order.)
List<Tuple> rows = selectFrom(order_workplaces)
.where(order_workplaces.order_id.eq(id))
.orderBy(order_workplaces.sequence_num.asc())
.list();
for (Tuple row : rows) {
workplaceIDsList.add(row.get(order_workplaces.workplace_id));
}
1 The AnyLogic database is a normal relational database --- HSQLDB in fact --- and databases only understand their own specific data types like VARCHAR, with AnyLogic and the libraries it uses translating these to Java types like String. In the user interface, AnyLogic makes it look like you set the column types as int, String, etc. but these are really the Java types that the columns' contents will ultimately be translated into.
AnyLogic does support columns which have option list types (and the special Code type column for columns containing executable Java code) but these are special cases using special logic under the covers to translate the column data (which is ultimately still a string of characters) into the appropriate option list instance or (for Code columns) into compiled-on-the-fly-and-then-executed Java).
Welcome to Stack Overflow :) To create a Population via Excel Import you have to create a method and call Code like this. You also need an empty Population.
int n = excelFile.getLastRowNum(YOUR_SHEET_NAME);
for(int i = FIRST_ROW; i <= n; i++){
String name = excelFile.getCellStringValue(YOUR_SHEET_NAME, i, 1);
double SEC_PARAMETER_TO_READ= excelFile.getCellNumericValue(YOUR_SHEET_NAME, i, 2);
WP workplace = add_wps(name, SEC_PARAMETER_TO_READ);
}
Now if you want to get a workplace by name, you have to create a method similar to your try.
Functionbody:
WP workplaceToFind = wps.findFirst(w -> w.name.equals(destinationName));
if(workplaceToFind != null){
//do what ever you want
}
I am trying to get some user attributes from Active Directry using Windows LDAP API. I am using:
Active Directory Version: The one that comes with Windows Server 2012
LDAP version: 3
Wldap32.lib version: The one that comes with Windows 10 x64
Eg:
PCHAR myAttributes[4];
myAttributes[0] = "DistinguishedName";
myAttributes[1] = "DisplayName";
myAttributes[2] = "PasswordExpired";
myAttributes[3] = "mail";
ldap_search_s(
myLdapConnection, // Ldap connection
myDomain, // DN to start search
LDAP_SCOPE_SUBTREE, // Scope
myFilter, // Filter
myAttributes, // Retrieve list of attributes
0, // Get both attributes and values
&mySearchResult // [out] Search results
);
It returns DistinguishedName, DisplayName and mail attributes, but does not reuturn the PasswordExpired attribute.
I queried with some other attributes and it looks like it does not return attributes with boolean values as well as the EmailAddress attribute.
Why does it not return PasswordExpired attribute?
What about EmailAddress ?
Is there a difference between EmailAddress and mail ?
There is no PasswordExpired LDAP attribute in Active Directory. To build your query look at this URL for attribute names in standard Active Directory schema https://msdn.microsoft.com/en-us/library/ms675090(v=vs.85).aspx. To check if password for given account is expired you'll need to check userAccountControl attribute, which is actually value storing flags of different states of user account https://msdn.microsoft.com/en-us/library/ms680832(v=vs.85).aspx. There is IADsUser interface that will translate this all for you in case you don't have to stick just to LDAP https://msdn.microsoft.com/en-us/library/aa746343(v=vs.85).aspx
You will find current primary email address in mail attribute. There is no EmailAddress LDAP attribute, unless you meant E-mail-Addresses which is CN for the same schema attribute as mail, so no difference there.
See above. In general if you do not have compelling reason to stick just to C/LDAP I'd recommend you to use .Net Framework instead. Otherwise you have a lot of work ahead of you - not just interpreting bit flags like in case of password expiration but possibly also with different authentication methods, different structures capturing time and date, accounting for timezones, UTF, chasing referrals and other stuff you might need depending on complexity of what you want to achieve. You will be productive much faster in .Net Framework. See DirectoryServices https://msdn.microsoft.com/en-us/library/mt481534(v=vs.110).aspx namespace or Security namespace https://msdn.microsoft.com/en-us/library/mt481561(v=vs.110).aspx for details.
Performance Engineering tool: LoadRunner 11
Protocol: Silverlight
The scenario:
1. A call is made (by the Silverlight application) to the web server to generate a unique identifier (UID)
2. The server returns a response with the UID
3. The application uses that UID to save Patient record (in this scenario, UID is Unique Patient Id)
The problem:
We would like to use the ID received in the Step 2's Web Response (say, as a local variable) and replace it in the next subsequent request sent by LoadRunner.
Please advise whether the same is possible.
*In parallel trying to figure out if "web_reg_save_param" will solve our problem.*
------------ LoadRunner data --------------------
1. Call to generate Uid
ignored as it is too large to paste here and irrelevant
2. Response from server (The UID is UNI-0000001544)

3. Next LoadRunner request where the UID (UNI-0000001543) has to be replaced with the UID received in the response
web_custom_request("SubmitChanges",
"URL=http://infinityappload/ClientBin/Infinity-Web-Services-ActorDomainService.svc/binary/SubmitChanges",
. . .
, "BodyBinary=#\rSubmitChanges\
. . .
\tPatientID\\x99\\x0EUNI-0000001543\
... LAST);
This is, as James said, the idea of correlation. The simplified approach would go as follows:
web_reg_save_param("UID2", "LB=GenerateSequenceResult™", "Savelen=14", LAST);
//The TM symbol will have to be replaced by whatever HTML code is used.
web_custom_request("WebRequest1", ....);
web_custom_request("SubmitChanges", "URL=http://infinityappload/...",
...
"BodyBinary=#\rSubmitChanges\",
"\tPatientID\\x99\\x0E{UID2}\",
LAST);
Values that are to be correlated are going to be determined prior to the request they will be populated by. They can then be used in any subsequent requests. Just make sure that, when using a correlated parameter, it is inside a quoted string.
The concept you are referring to is the management of correlated variables, it is a core concept in the use of performance test tools, LoadRunner included. This particular concept is the subject of nearly 1/3 of the standard LoadRunner script development product training. I would refer you to information on correlation for both web and silverlight protocols in the system documentation. Also, it is critical for your short and long term success that you pair yourself with both a strong mentor as well as attending some form of standard product training.
I need to aggregate a number of csv inbound files in-memory, if necessary resequencing them, on Mule ESB CE 3.2.1.
How could I implement this kind of logics?
I tried with message-chunking-aggregator-router, but it fails on startup because xsd schema does not admit such a configuration:
<message-chunking-aggregator-router timeout="20000" failOnTimeout="false" >
<expression-message-info-mapping correlationIdExpression="#[header:correlation]"/>
</message-chunking-aggregator-router>
I've also tried to attach mine correlation ids to inbound messages, then process them by a custom-aggregator, but I've found that Mule internally uses a key made up of:
Serializable key=event.getId()+event.getMessage().getCorrelationSequence();//EventGroup:264
The internal id is everytime different (also if correlation sequence is correct): this way, Mule does not use only correlation sequence as I expected and same message is processed many times.
Finally, I can re-write a custom aggregator, but I would like to use a more consolidated technique.
Thanks in advance,
Gabriele
UPDATE
I've tried with message-chunk-aggregator but it doesn't fit my requisite, as it admits duplicates.
I try to detail the scenario I need to cover:
Mule polls (on a SFTP location)
file 1 "FIXEDPREFIX_1_of_2.zip" is detected and kept in memory somewhere (as an open SFTPStream, it's ok).
Some correlation info are mantained for grouping: group, sequence, group size.
file 1 "FIXEDPREFIX_1_of_2.zip" is detected again, but cannot be inserted because would be duplicated
file 2 "FIXEDPREFIX_2_of_2.zip" is detected, and correctly added
stated that group size has been reached, Mule routes MessageCollection with the correct set of messages
About point 2., I'm lucky enough to get info from filename and put them into MuleMessage::correlation* properties, so that subsequent components could use them.
I did, but duplicates are processed the same.
Thanks again
Gabriele
