I want run a foreach loop in a HtmlNode which has been parsed from internet via HtmlWebclass and loadFromWebAsync method. Before running the loop I want to make sure the that the node exists in the HtmlDocument. How do I check that without the help Xpath query because many of the Windows RT and Windows 8.1 version doesn't work with this.
You can use LINQ .Any() method to check if sequence contains any element, for example :
var doc = new HtmlDocument();
.....
var isDivExist = doc.DocumentNode
.Descendants("div")
.Any();
Or to check if any node in the sequence satisfies specific condition :
var isDivWithSpecificClassExist = doc.DocumentNode
.Descendants("div")
.Any(d => .GetAttributeValue("class", "") == "foo");

I'm trying to add new names to the address book programmatically but I'm getting the following error:
[TypeError] Exception occurred calling method NotesDocument.replaceItemValue(string, Array)
Unknown or unsupported object type in Vector
Code snippet below:
var addressBook = session.getDatabase("","names.nsf");
var gView:NotesView = addressBook.getView("($VIMGroups)");
var gDoc:NotesDocument = gView.getDocumentByKey("groupName", true);
var newg:java.util.Vector = [];
var mems:java.util.Vector = new Array(gDoc.getItemValue('Members'));
newg.push(mems);
var newNames:java.util.Vector = new Array(getComponent("NewMems").getValue());
newg.push(newNames);
gDoc.replaceItemValue("Members", newg);
gDoc.save();
Adding a single user works fine, but then it does not save users in the required canonical format below:
CN=John Doe/O=Org
Instead it is saved in the original format below:
John Doe/Org
I look forward to your suggestions. Thanks.
You can't store an Array in a field. Make newg a java.util.Vector instead and integrate with that.
For OpenNTF Domino API the team wrote a lot of code to auto-convert to Vectors, which may cover Arrays.
Don't use an Array (which is a JS thing). Initialize it as a Vector.
var newg:java.util.Vector = new java.util.Vectory();
Then look up the Vector methods to see how to add to that vector. Not sure if you will have to convert the names using the Name method but I would store them as "CN=Joe Smith/O=Test Org" to be sure you got the right format.
I was able to solve the issue using a forloop to loop through the list and push it into a newly created array. Using the forloop seems to make the difference.
var newg = [];
var group = new Array(getComponent("NewMems").getValue()), lenGA = group.length;
for(i = 0; i < lenGA; i++){
newg.push(group[i]);
}
gDoc.replaceItemValue("Members", newg);
gDoc.save();
An explanation about this behaviour will be appreciated.
I'm using the Chrome driver and Selenium tools in my CodedUI tests. I can find the element I need using the SearchProperties and a Contains operator however I need the full Id for subsequent searches.
For example I need to find an input element with Id "pm_modal_28".
This is easy enough by doing a search where Id contains "pm_modal".
I then need to parse the value "28" out of the Id that was found so I can search for the next nested element which has an Id of "dp_28".
When I use the Id property of HtmlDiv I get a NotSupportedException. Is there anyway I can get all of the Html attributes from an Element or get the Id from an element after it has been found?
Not sure if this what you are after, once the control is identified, you would have all its properties to play around with.
For example
var control = new HtmlDiv ();
control.SearchProperties.Add("Id", "MyDiv_28");
if (!control.TryFind()) return;
var newControl = new HtmlDiv();
newControl.SearchProperties.Add("Id", control.Id.Split('_')[1]);
newControl.TryFind();
HtmlDiv myDiv = new HtmlDiv(browser);
//Add the search logic u want !
myDiv.SearchProperties.Add("class", "ClassName");
string onewayforID = myDiv.Id;
string anotherWay = myDiv.GetProperty(HtmlDiv.PropertyNames.Id).ToString(); // Or u can simpy pass "Id"
See if that Works !
I am using Fluent NHibernate for my ORM. In doing so I am trying to use the NHibernate LINQ syntax to fetch a set of data with the power of LINQ. The code I have works and executes correctly with the exception being that a timeout is thrown if it takes longer than roughly 30 seconds to run. The question I have is how do I extend the default 30 second timeout for LINQ statements via NHibernate?
I have already seen the posts here, here, and here but the first two refer to setting the DataContext's Timeout property, which does not apply here, and the third refers to setting the timeout in XML, which also does not apply because I am using Fluent NHibernate to generate the XML on the fly. Not only that but the post is 2 years old and Fluent NHibernate has changed since.
With the ICriteria objects and even HQL I can specify the timeout, however that is not the goal here. I would like to know how to set that same timeout and use LINQ.
Example code:
using (var session = SessionFactory.OpenSession())
using (var transaction = session.BeginTransaction())
{
var query = (from mem in session.Query<Member>()
select mem);
query = query.Where({where statement});
int start = (currentPage - 1) * max);
if (start > 0)
query = query.Skip(start).Take(max);
else
query = query.Take(max);
var list = query.ToList();
transaction.Commit();
return list;
}
This code (where statement does not matter) works for all purposes except where a timeout occurs.
Any help is appreciated. Thanks in advance!
I ended up setting the command timeout for the Configuration for Fluent NHibernate. The downside to this is that it sets the timeout for ALL of my data access calls and not just the one.
Example code:
.ExposeConfiguration(c => c.SetProperty("command_timeout", (TimeSpan.FromMinutes(10).TotalSeconds).ToString()))
I found this suggestion from this website.
Nhibernate has extended the IQueryable and added a few methods https://github.com/nhibernate/nhibernate-core/blob/master/src/NHibernate/Linq/LinqExtensionMethods.cs
var query = (from c in Session.Query<Puppy>()).Timeout(12);
or
var query = (from c in Session.Query<Puppy>());
query.Timeout(456);
I've just spent fair amount of time fighting with this and hopefully this will save someone else some time.
You should use the .Timeout(120) method call at the very last moment to make sure it is used. TBH I'm not 100% sure on why this is but here are some examples:
WILL WORK
query = query.Where(x => x.Id = 123);
var result = query.Timeout(120).ToList();
DOESN'T WORK
query.Timeout(120);
query = query.Where(x => x.Id = 123);
var result = query.ToList();
If done like the second (DOESN'T WORK) example, it seems to fall back to the default System.Transaction.TransactionManager.DefaultTimeout.
Just in case anyone is still looking for this and finds this old thread too...
Query.Timeout is deprecated.
You should use WithOptions instead:
.WithOptions(o => o.SetTimeout(databaseTimeoutInSeconds))
Ok this seems so silly but I'm having some trouble getting this to work. I want to do an #DbColumn() or #DbLookup() to another database. Same server - BUT it's in a folder. And I can't get a result. The view of the database in question is sorted by the first column.
I'm trying to populate choices of a combobox.
I've tried that built in #DbColumn():
var dbname = new Array("", "myfolder\\myDB.nsf");
return #DbColumn(dbname, "byCode", 0)
I've tried that with and without the "double slashes" and with column 0 and also column 1.
I've also tried the XSnippet :
http://openntf.org/XSnippets.nsf/snippet.xsp?id=dblookup-dbcolumn-with-cache-sort-and-unique
That would be my preferred method really because of caching. I tried creating a SSJS function:
function getFacilityList() {
var dbPath = database.getFilePath().split(database.getFileName())[0];
return DbColumnArray("","myfolder\\myDB.nsf","cache", "sort", "byCode", 0)
}
Which I think should have worked but did not.
Any thoughts would be appreciated! Thanks
Try:
var dbname = session.getServerName() + "!!" + "myfolder\\myDB.nsf";
return #DbColumn(dbname, "byCode", 0)
I need to parse an XLIFF file using C#, but I'm having some trouble. These files are fairly complex, containing a huge amount of nodes.
Basically, all I need to do is read the source node from each trans-unit node, do some processing on it, and insert the processed text into the corresponding target node (which will always be present, but empty).
An example of one of the nodes I need to parse would be (the whole file may contain 100s of these):
<trans-unit id="0000000002" datatype="text" restype="string">
<source>Windows Update is not installed</source>
<target/>
<iws:segment-metadata tm_score="0.00" ws_word_count="6" max_segment_length="0">
<iws:status target_content="placeholders_only"/>
</iws:segment-metadata>
<iws:boundary-seg sequence="bs20721"/>
<iws:markup-seg sequence="0000000001">
</trans-unit>
The trans-unit nodes can be buried deep in the files, the header section contains a lot of data. I'd like to use LINQ to XML to read the data, but I'm not having any luck getting it to work. Here's my current code (just trying to read and output the source nodes from the file:
XDocument doc = XDocument.Load(path);
Console.WriteLine("Before loop");
foreach (var transUnitNode in doc.Descendants("trans-unit"))
{
Console.WriteLine("In loop");
XElement sourceNode = transUnitNode.Element("source");
XElement targetNode = transUnitNode.Element("target");
Console.WriteLine("Source: " + sourceNode.Value);
}
I never see 'In loop' and I don't know why, can someone tell me what I'm doing wrong here, or suggest a better way to achieve what I'm trying to do here?
Thanks.
Try
XNamespace df = doc.Root.Name.Namespace;
foreach (XElement transUnitNode in doc.Descendants(df + "trans-unit"))
{
XElement sourceNode = transUnitNode.Element(df + "source");
// and so one, use the df namespace object to qualify any elements names
}
