I would like to modify the "name" attribute of an amazon instance. See attached screenshot. I need to do it programmatically, but can't find anywhere in the EC2 API how to set that.
If it matters, I'm launching these via a spot request through their API. I would like to set the field that I tagged, "set this name" in the image below.
This might help...
AmazonEC2 ec2;
AWSCredentials credentials;
String accKey = "your access key";
String secKey = "your secret key";
credentials = new BasicAWSCredentials(accKey, secKey);
ec2 = new AmazonEC2Client(credentials);
String instanceId = "Your Instance ID";
List<Tag> tags = new ArrayList<Tag>();
Tag t = new Tag();
t.setKey("Name");
t.setValue("my server!");
tags.add(t);
Tag t = new Tag();
t.setKey("owner");
t.setValue("me");
tags.add(t);
CreateTagsRequest ctr = new CreateTagsRequest();
ctr.setTags(tags);
ctr.withResources(instanceId);
ec2.createTags(ctr);
kind of quick and dirty, but you get the idea.
You can do it through AWS console UI:
In 2021 this can be done from the AWS console, by going to EC2 > Instances, clicking the instance ID, then in the bottom panel clicking on the Tags tab, and clicking Manage tags. From there, you can simply change the value of the Name tag then click Save to apply.
Further digging into the API and I found what I was looking for.
These are known as tags. You can assign them to nearly any aws entity (some things are excepted, e.g., you can't add a tag to an elastic ip).
You can set keyname/keyvalue pairs through the API. Documentation is here: http://docs.amazonwebservices.com/AWSEC2/latest/APIReference/ApiReference-query-CreateTags.html
Then you can filter results by these tags, or choose to display them in the web interface.

I am programmatically setting up a cluster resource (specifically, a Generic Service), using the Windows MI API (Microsoft.Management.Infrastructure).
I can add the service resource just fine. However, my service requires the "Use Network Name for computer name" checkbox to be checked (this is available in the Cluster Manager UI by looking at the Properties for the resource).
I can't figure out how to set this using the MI API. I have searched MSDN and multiple other resources for this without luck. Does anybody know if this is possible? Scripting with Powershell would be fine as well.
I was able to figure this out, after a lot of trial and error, and the discovery of an API bug along the way.
It turns out cluster resource objects have a property called PrivateProperties, which is basically a property bag. Inside, there's a property called UseNetworkName, which corresponds to the checkbox in the UI (and also, the ServiceName property, which is also required for things to work).
The 'wbemtest' tool was invaluable in finding this out. Once you open the resource instance in it, you have to double-click the PrivateProperties property to bring up a dialog which has a "View Embedded" button, which is then what shows you the properties inside. Somehow I had missed this before.
Now, setting this property was yet another pain. Due to what looks like a bug in the API, retrieving the resource instance with CimSession.GetInstance() does not populate property values. This misled me into thinking I had to add the PrivateProperties property and its inner properties myself, which only resulted in lots of cryptic errors.
I finally stumbled upon this old MSDN post about it, where I realized the property is dynamic and automatically set by WMI. So, in the end, all you have to do is know how to get the property bag using CimSession.QueryInstances(), so you can then set the inner properties like any other property.
This is what the whole thing looks like (I ommitted the code for adding the resource):
using (var session = CimSession.Create("YOUR_CLUSTER", new DComSessionOptions()))
{
// This query finds the newly created resource and fills in the
// private props we'll change. We have to do a manual WQL query
// because CimSession.GetInstance doesn't populate prop values.
var query =
"SELECT PrivateProperties FROM MSCluster_Resource WHERE Id=\"{YOUR-RES-GUID}\"";
// Lookup the resource. For some reason QueryInstances does not like
// the namespace in the regular form - it must be exactly like this
// for the call to work!
var res = session.QueryInstances(#"root/mscluster", "WQL", query).First();
// Add net name dependency so setting UseNetworkName works.
session.InvokeMethod(
res,
"AddDependency",
new CimMethodParametersCollection
{
CimMethodParameter.Create(
"Resource", "YOUR_NET_NAME_HERE", CimFlags.Parameter)
});
// Get private prop bag and set our props.
var privProps =
(CimInstance)res.CimInstanceProperties["PrivateProperties"].Value;
privProps.CimInstanceProperties["ServiceName"].Value = "YOUR_SVC_HERE";
privProps.CimInstanceProperties["UseNetworkName"].Value = 1;
// Persist the changes.
session.ModifyInstance(#"\root\mscluster", res);
}
Note how the quirks in the API make things more complicated than they should be: QueryInstances expects the namespace in a special way, and also, if you don't add the network name dependency first, setting private properties fails silently.
Finally, I also figured out how to set this through PowerShell. You have to use the Set-ClusterParameter command, see this other answer for the full info.
I have tried to save login value as true if user has logged in once by using
Application.Current.Properties["isLoggedIn"] = "true";
but its not working. If i remove my app from background it again shows the login page but if user is logged in it should show the next page.
When using 'Application Properties Dictionary' you have to keep in mind few things:
According to the official documentation: 'The Properties dictionary is saved to the device automatically'. However, if you want to ensure persistence you have to explicitly call SavePropertiesAsync().
The Properties dictionary can only serialize primitive types for storage. Attempting to store other types such as List can fail silently.
Read the official documentation carefully and pay attention to details. Here is a code example:
private async Task SaveApplicationProperty<T>(string key, T value)
{
Xamarin.Forms.Application.Current.Properties[key] = value;
await Xamarin.Forms.Application.Current.SavePropertiesAsync();
}
private T LoadApplicationProperty<T>(string key)
{
return (T) Xamarin.Forms.Application.Current.Properties[key];
}
// To save your property
await SaveApplicationProperty("isLoggedIn", true);
// To load your property
bool isLoggedIn = LoadApplicationProperty<bool>("isLoggedIn");
Base on your needs you may consider Local Database or Settings Plugin instead. However for saving just a few primitive values Application Properties approach should be good enough.
Xamarin Forms now includes Xamarin Forms Essentials and contains the Preferences component that you need. Check out the official website and try it.
https://learn.microsoft.com/en-us/xamarin/essentials/preferences?tabs=ios
This is an example of how to manage preferences with Essentials.
To save a value for a given key in preferences:
Preferences.Set("my_key", "my_value");
To retrieve a value from preferences or a default if not set:
var myValue = Preferences.Get("my_key", "default_value");
To remove the key from preferences:
Preferences.Remove("my_key");
To remove all preferences:
Preferences.Clear();
Supported Data Types:
bool
double
int
float
long
string
DateTime
First we set the key and value using below code
Xamarin.Essentials.Preferences.Set("UserId", content.userId);
We can get the above value in any page of project using below code
Xamarin.Essentials.Preferences.Get("UserId", "");
I am using google image search API. Till yesterday it was working, but today morning it says "This API is no longer available"
Is it officially closed, Or any error at my side
Request
https://ajax.googleapis.com/ajax/services/search/images?v=1.0&rsz=8&q=cute+kittens
Response
{"responseData": null, "responseDetails": "This API is no longer available.", "responseStatus": 403}
The answer I found was using Google's Custom Search Engine (CSE) API. Note that this is limited to 100 free requests per day.
Creating cx and modifying it to search for images
Create custom search engine at https://cse.google.com/cse/create/new based on your search criteria.
Choose sites to search (leave this blank if you want to search the entire web, otherwise you can enter a site to search in one particular site)
Enter a name and a language for your search engine.
Click "create." You can now find cx in your browser URL.
Under "Modify your search engine," click the "Control Panel" button. In the "edit" section you will find an "Image Search" label with an ON/OFF button, change it to ON. Click "update" to save your changes.
Conducting a search with the API
The API endpoint url is https://www.googleapis.com/customsearch/v1
The following JSON parameters are used for this API:
q: specifies search text
num: specifies number of results. Requires an integer value between 1 and 10 (inclusive)
start: the "offset" for the results, which result the search should start at. Requires an integer value between 1 and 101.
imgSize: the size of the image. I used "medium"
searchType: must be set to "image"
filetype: specifies the file type for the image. I used `"jpg", but you can leave this out if file extension doesn't matter to you.
key: an API key, obtained from https://console.developers.google.com/
cx: the custom search engine ID from the previous section
Simply make a GET request by passing above parameters as JSON to the API endpoint (also listed above).
Note: If you set a list of referrers in the search engine settings, visiting the URL via your browser will likely not work. You will need to make an AJAX call (or the equivalent from another language) from a server specified in this list. It will work for only the referrers which were specified in the configuration settings.
Reference:
https://developers.google.com/custom-search/json-api/v1/reference/cse/list
Now You can search images with Custom image search API.
You can do this with two steps:
Get CUSTOM_SEARCH_ID
Go to - https://cse.google.ru/cse/all
Here you must create new Search Engine. Do this and enable Image Search at there.
Screen(i am Russian... sorry)
then get this search engine ID. To do this press at Get Code button:
And there find line with cx = "here will be your CUSTOM_SEARCH_ID":
Ok. It's done, now second step:
Get SERVER_KEY
Go to google Console - https://console.developers.google.com/project
Press to Create project button, enter the name and other required information.
Pick this project and go to Enable Apis
Now find Custom Search Engine.
And Enable it.
Now we must go to Credentials and create new Server Key:
Ok. Now we can use Image Search.
Query:
https://www.googleapis.com/customsearch/v1?key=SERVER_KEY&cx=CUSTOM_SEARCH_ID&q=flower&searchType=image&fileType=jpg&imgSize=xlarge&alt=json
Replace the SERVER_KEY and CUSTOM_SEARCH_ID and call this request.
Limit: for free you can search only 100 images per day.
If this is just for your own purposes (not for production) and you're not planning to abuse Google Image Search, you can simply extract first image URL from Google search results using JSOUP.
For example:
Code to retrieve image URL of the first thumbnail:
public static String FindImage(String question, String ua) {
String finRes = "";
try {
String googleUrl = "https://www.google.com/search?tbm=isch&q=" + question.replace(",", "");
Document doc1 = Jsoup.connect(googleUrl).userAgent(ua).timeout(10 * 1000).get();
Element media = doc1.select("[data-src]").first();
String finUrl = media.attr("abs:data-src");
finRes= "<img src=\"" + finUrl.replace(""", "") + "\" border=1/>";
} catch (Exception e) {
System.out.println(e);
}
return finRes;
}
Guide:
question - image search term
ua - user agent of the browser
After I read several responses I compiled a response with images:
Access the website: https://developers.google.com/custom-search/v1/introduction, on the page you will find this part, so click in the button Get a Key:
Create or select a project, and then NEXT:
Copy the API KEY:
Access the website to create your CX: https://cse.google.com/cse/create/new, write some random domain like “www.anypage.com”, (after we will delete), select a language, and define some name for your search engine. Click on the Button CREATE.
Will see this page, then click in Control Panel:
Copy the Search engine ID for later (this is your CX). After you can set to search in all websites (active Search the entire web, select on the random website www.anypage.com then click on the button Delete) and you can active Image search. So will see like this:
And Using REST you can get the results, using this example code (searching for flower):
<html lang="pt">
<head>
<title>JSON Custom Search API Example</title>
</head>
<body>
<div id="content"></div>
<script>
function hndlr(response) {
console.log(response);
for (var i = 0; i < response.items.length; i++) {
var item = response.items[i];
// in production code, item.htmlTitle should have the HTML entities escaped.
document.getElementById("content").innerHTML += "<br>" + item.htmlTitle;
}
}
</script>
<script src="https://www.googleapis.com/customsearch/v1?key=API_KEY&cx=SEARCH_ENGINE_KEY&q=flower&searchType=image&callback=hndlr"></script>
</body>
</html>
The base code is found here: https://developers.google.com/custom-search/v1/using_rest
After setting your API_KEY (key) and your SEARCH ENGINE KEY (cx), the result will see like this:
Thanks to #Vijay Shegokar, #aftamat4ik and #Alladinian
This is the full URL template to be used
We can eliminate unnecessary parameters.

I am using
https://www.googleapis.com/customsearch/v1?key=ap_key&cx=cx&q=hello&searchType=image&imgSize=xlarge&alt=json&num=10&start=1
Change the API url to
Google Custom Image search
Provide the same parameters along with with API KEY and CX.

I'm building a web service for a client that pulls data from the Sitefinity CMS. The problem is they want to pass in a Guid for the service and receive the info about this item. No problem except I only have been able to locate the "live" Guid for one Item (and that was by combing through the HTML in the back end).
I was going to look at the tables in SQL Server but I'm not sure which table to look at. The content items have several tables all related of course and there isn't any documentation on how to look at this. I can find plenty of documentation on querying the master Guid, but no place to find it.
Oh, and these are custom content types built by the Module Builder.
Any Help would be SOOOOO appreciated!
var master = DynamicModuleManager.GetManager().Lifecycle.GetMaster(<liveGuidHere>);
One of the biggest consumers of Sitefinity webservices is Sitefinity. The best place to start looking for that guid is to take a look at what web service calls are being made when you pull up your custom content item list in the backend. I used the chrome developer tools and check in the network tab.
One I found for a stores module made with module builder was something to the effect of http://www.testsite.com/Sitefinity/Services/DynamicModules/Data.svc/?managerType=Telerik.Sitefinity.DynamicModules.DynamicModuleManager&providerName=OpenAccessProvider&itemType=Telerik.Sitefinity.DynamicTypes.Model.Stores.Store&provider=OpenAccessProvider&sortExpression=LastModified%20DESC&skip=0&take=50
The json this returns is a list of all the masters with their ids (note in the list that the content items all have have a status of 0) http://www.sitefinity.com/documentation/documentationarticles/developers-guide/sitefinity-essentials/modules/content-lifecycle
When you go to Administration / Module Builder / Your Module, you will see a link to the API on the top right corner.
This link goes to a page full of API examples for your particular module which is kind of cool.
Basically you would have to find your item first using LINQ and the GetValue extension method.
Once you have the item you can get its ID or any other property.
using Telerik.Sitefinity.Utilities.TypeConverters;
using Telerik.Sitefinity.DynamicModules;
using Telerik.Sitefinity.Model;
....
var mgr = DynamicModuleManager.GetManager();
var countrymasters = from ctry in mgr.GetDataItems(TypeResolutionService.ResolveType("Telerik.Sitefinity.DynamicTypes.Model.Destinations.Destination"))
where ctry.GetValue<string>("culture") == siteid &&
(ctry.Status == Telerik.Sitefinity.GenericContent.Model.ContentLifecycleStatus.Live && ctry.Visible == true)
select new
{
airport_cd = ctry.GetValue<string>("airport_cd"),
country_master_cd = ctry.GetValue<string>("country_master_cd")
};
I am not able to find a way (even with Mango SDK) in which I can show a chooser (say PhoneNumberChooserTask), and get all details about a contact...
Only Name and PhoneNumber is available. For other information like address, I have to use a different chooser. Is there any way in which I can show a chooser (anyone) and get all details...
Phone number
Email address
Photo of the contact
etc.
let me clarify the issue here...
The following code will not work. I want to show a chooser in such a way that it grabs all details. Showing multiple choosers, as I said is not what I want. Imagine asking someone to choose the same contact 3 times to get Email, PhoneNumber and Address.
EmailAddressChooserTask ect = new EmailAddressChooserTask();
ect.Completed += new EventHandler<EmailResult>(ect_Completed);
ect.Show();
PhoneNumberChooserTask pct = new PhoneNumberChooserTask();
pct.Completed += new EventHandler<PhoneNumberResult>(pct_Completed);
pct.Show();
AddressChooserTask act = new AddressChooserTask();
act.Completed += new EventHandler<AddressResult>(act_Completed);
act.Show();
In v7.1 (Mango) you can use the Contacts class. You can use the SearchAsync method providing whatever search criteria you want (DisplayName is the most likely) and then handle the SearchCompleted event and use the ContactsSearchEventArgs.Results to access the returned Contact objects.
From there, you can use the GetPicture method to retrieve the contact image, and the various properties of the Contact object to access all the other information.
Hopefully that will get you started. You can find more information in the Microsoft.Phone.UserData namespace.
I think you can do this with the following tasks:
AddressChooserTask
EmailAddressChooserTask
PhoneNumberChooserTask
