I am currently trying to retrieve a unique device identifier. Here is my code:
var token = Windows.System.Profile.HardwareIdentification.getPackageSpecificToken(null);
var reader = Windows.Storage.Streams.DataReader.fromBuffer(token.id);
reader.unicodeEncoding = true;
var identifier = reader.readString(reader.unconsumedBufferLength);
console.log(identifier);
But it raises following error:
The operation attempted to access data outside the valid range.
How can I retrieve the size of my token.id string? I also tried to use token.id.length, but result is the same.
I can't try to replicate what you're doing at the moment, but you might try reading it as bytes into array like this:
var array = new Array(token.id.length);
reader.readBytes(array);
And then convert the array to a string for the identifier.
See these posts for examples:

Hi have been getting an error stating.. Object Expected for these 2 lines of code:
function AsyncSave(send) {
//alert ('In CustomSave');
var drp = document.getElementById("Sample_sample_DropDownChoice");
var drpValue = drp.options[drp.selectedIndex].value;
var varAnalysis = getTagFromIdentifierAndTitle("textarea","TextField","Principal Comments");
var varAnalysisTextBoxID = RTE_GetEditorDocument(varAnalysis.id);
var varAnalysisText = varAnalysisTextBoxID.body.innerText;
alert ('Save N Send');
alert (drpValue);
alert (varAnalysisText);
Error Happens when it gets to the line below
var queryStringVals = $().SPServices.SPGetQueryString();
var itemID = queryStringVals["itemID"];
What could be the problem.. should I be running different up to date SPServices.. this is 2010 btw.
The goal is to take the values entered, save them, and update them (send) to another form/List.
SharePoint 2010 has a built-in JavaScript method for retrieving values from the query string. Try using the following:
var itemID = GetUrlKeyValue("itemID");
That's assuming the URL of the page on which the script is running actually has a query string parameter of "itemID"
I'm trying to build a query to get the numbers of rows that have the same data on a column (my column is ESTADO).
var db = Database.Open("MyDB");
var selectedData = db.Query("SELECT COUNT (*) FROM graficos WHERE ESTADO='FECHADO'");
var data = db.QueryValue(selectedData);
But when i try to run it gives the following error:
Compiler Error Message: CS1502: The best overloaded method match for 'WebMatrix.Data.Database.QueryValue(string, params object[])' has some invalid arguments
Line 51: var data = db.QueryValue(selectedData);
Pass the query directly to the QueryValue() method.
var data = db.QueryValue("SELECT COUNT (*) FROM graficos WHERE ESTADO='FECHADO'");
Read this documentation for more information on how to use the Database.QueryValue() method.
jsonStoreInit = function(pSuccess, pFailure){
collections={};
collections['objects'] = {};
var options = {};
options.localKeyGen = false;
options.clear = false;
options.username = app.username;
options.password = app.password;
options.additionalSearchFields = {key: 'string'};
WL.JSONStore.init(collections, options)
.then(pSuccess)
.fail(pFailure);
};
putObject = function(pObject) {
var keyValue = pObject.getKey();
var object = {myObject : pObject.getKey()};
var options = {};
//options.additionalSearchFields = {key : keyValue};
WL.JSONStore.get("objects")
.add(object, options);
};
I'm on WL 6.0 FP 1
In the code sample above jsonStoreInit is what I use to init my store including the options.additionalSearchFields.
When I come to add the objects in the putObject funciton it works fine with the additionalSearchFields commented out, but when I uncomment it to add the additional fields I get an error
[wl.jsonstore] {"src":"store","err":21,"msg":"INVALID_ADD_INDEX_KEY","col":"objects","usr":"xxxx","doc":{},"res":{}}
When I look this error message up all I get is
21 INVALID_ADD_INDEX_KEY
Problem with additional search fields.
Which I had kinda figured ... can anyone provide any help on this ...
I don't need to you fix my code but if you could point me to a working example that would be excellent.
Many thanks, ownimage
The person that asked the question solved it, but I'm leaving this answer in case someone is wondering how to pass data that uses additionalSearchFields.
Example:
var data = {hello: 'world'};
WL.JSONStore.get('collection').add(data, {additionalSearchFields: {key: 'value'}})
The example assumes the collection was created with a search field for hello as string and an additional search field for key as string. It also assumes there's a collection initialized called collection.
I'm using node js 0.10.12 to perform querys to postgreSQL 9.1.
I get the error error invalid input synatx for integer: "{39}" (39 is an example number) when I try to perform an update query
I cannot see what is going wrong. Any advise?
Here is my code (snippets) in the front-end
//this is global
var gid=0;
//set websockets to search - works fine
var sd = new WebSocket("ws://localhost:0000");
sd.onmessage = function (evt)
{
//get data, parse it, because there is more than one vars, pass id to gid
var received_msg = evt.data;
var packet = JSON.parse(received_msg);
var tid = packet['tid'];
gid=tid;
}
//when user clicks button, set websockets to send id and other data, to perform update query
var sa = new WebSocket("ws://localhost:0000");
sa.onopen = function(){
sa.send(JSON.stringify({
command:'typesave',
indi:gid,
name:document.getElementById("typename").value,
}));
sa.onmessage = function (evt) {
alert("Saved");
sa.close;
gid=0;//make gid 0 again, for re-use
}
And the back -end (query)
var query=client.query("UPDATE type SET t_name=$1,t_color=$2 WHERE t_id = $3 ",[name, color, indi])
query.on("row", function (row, result) {
result.addRow(row);
});
query.on("end", function (result) {
connection.send("o");
client.end();
});
Why this not work and the number does not get recognized?
Thanks in advance
As one would expect from the initial problem, your database driver is sending in an integer array of one member into a field for an integer. PostgreSQL rightly rejects the data and return an error. '{39}' in PostgreSQL terms is exactly equivalent to ARRAY[39] using an array constructor and [39] in JSON.
Now, obviously you can just change your query call to pull the first item out of the JSON array. and send that instead of the whole array, but I would be worried about what happens if things change and you get multiple values. You may want to look at separating that logic out for this data structure.
I'm working (actually more like playing) around with the Bit.ly API, and keep getting the error in the title of this question. So I'm going to show you the code and hopefuly someone can help me resolve this. First the client side code.
var x = service.GetClicks(url, service.BitlyLogin, service.BitlyAPIKey);
Console.WriteLine(x);
Console.ReadLine();
And this is the code that's being called
public List<int> GetClicks(string url, string login, string key)
{
List<int> clicks = new List<int>();
url = Uri.EscapeUriString(url);
string reqUri =
String.Format("http://api.bit.ly/v3/clicks?" +
"login={0}&apiKey={1}&shortUrl={2}&format=xml" +
login, key, url);
HttpWebRequest req = (HttpWebRequest)WebRequest.Create(reqUri);
req.Timeout = 10000; // 10 seconds
Stream stm = req.GetResponse().GetResponseStream();
XmlDocument doc = new XmlDocument();
doc.Load(stm);
// error checking for xml
if (doc["response"]["status_code"].InnerText != "200")
throw new WebException(doc["response"]["status_txt"].InnerText);
XmlElement el = doc["response"]["data"]["clicks"];
clicks.Add(int.Parse(el["global_clicks"].InnerText));
clicks.Add(int.Parse(el["user_clicks"].InnerText));
return clicks;
}
As you can see it's very simple code, nothing complicated, and I can see nothing that causes this error. Anyone out there who has worked with(the full error is Index (zero based) must be greater than or equal to zero and less than the size of the argument list.) the Bit.ly API and can lend a hand?
Instead this
string reqUri =
String.Format("http://api.bit.ly/v3/clicks?" +
"login={0}&apiKey={1}&shortUrl={2}&format=xml" + login, key, url);
Use this
string reqUri = String.Format("http://api.bit.ly/v3/clicks?login={0}&apiKey={1}&shortUrl={2}&format=xml", login, key, url);
Notice that I just changed the plus sign with the comma before "login, key, url);" at the end of the String.Format().
I narrowed it down to a place where I was using string.Format to build an array and has less in the string.Format than what was supposed to. I had it go to Index 3 but only filled to Index 2
Not for your specific case, but I ran into this: make sure that, if you have multiple parameters, you send them as an array of objects instead of an IEnumerable:
IEnumerable<object> myArgs = ...;
string toFormat = "{0} xyz {1}";
String.Format(toFormat, myArgs);
// ERROR, since myArgs is one argument whereas the string template requires two
String.Format(toFormat, myArgs.ToArray());
// Valid, as the Format() accepts an array of objects to fill all arguments in the string
