I have written code to get latest from TFS using the client APIs. I would like to be updated on the progress and I understand that the properties "Total" and "Current" of GettingEventArgs can be used. But these properties are not visible during design time but only visible at runtime (see image below). But event at runtime, I am unable to fetch them using reflection as give below.
static void versionControl_Getting(object sender, GettingEventArgs e)
{
GettingEventArgs status = (GettingEventArgs)e;
int curr = (int)status.GetType().GetProperty("Current").GetValue(status, null);
int tot = (int)status.GetType().GetProperty("Total").GetValue(status, null);
}
This does not find the property and I get a Null reference on the "GetProperty". I hope the syntax is correct.
Any thoughts on how to get hold of these property values?
There is an error in GettingEventArgs status = (GettingEventArgs)e;. You probably ment
OperationStatus status = e.Status;

If I have an object like Browsers.Item("iexplore") and if it has a property called IsOpen ,
how to print it in test complete log
I am using Jscript for scripting
Test complete is version 9
If you need to check whether a browser is running, you can do this in the following manner:
function test()
{
var b = Sys.WaitBrowser("iexplore");
if (b.Exists == true)
Log.Message("Internet Explorer is running");
else
Log.Message("Internet Explorer is not running");
}
To get a value of an object's property, just address this property using the dot notation: object.property. To post this value to the test log, call the Log.Message method. Use the Log.Warning and Log.Error methods to post warnings and errors correspondingly.
Log.Message(obj.MyProperty);
You could use any of these:
var yourObject = ..
console.info(yourObject);
console.log(yourObject);
console.log(yourObject.yourProperty);
I'm getting the Instance ID of an object from collision_line()
Now that I have this instance, I want to get it's image_angle, but I get an 'unknown variable' message when I try that.
What should I do?
what is the value of this collision_line()? The collision_line() function returns an instance id - however when nothing is found it returns noone (-4).. So you'll have to test for that first:
var inst, imgangle;
inst = collision_line(...);
if (inst != noone) {
imgangle = inst.image_angle;
//etc etc
}
or alternativelly (more cleanly in GM), we can "abuse" the with statement. With executes all following code from the perspective of the given instance id (or for all instances of a certain object when given the object id).
However the value noone will automatically prevent any execution.
var inst, imgangle;
inst = collision_line(...);
with (inst) {
imgangle = image_angle;
//note that we do no longer have to put "inst." before getting a variable
//etc etc
}
Ektron 8.0.1 SP1
I am using SmartForms and Content Types to read (and hopefully write) data. I can read data but now I am attempting to write a new record similar to the following.
ContentTypeManager<member> contentTypeManager = new ContentTypeManager<member>();
ContentType<member> newmem = new ContentType<member>();
newmem.SmartForm.details.field1 = "Chuck"; // This line throws 'Object reference not set to an instance of an object.' error
newmem.SmartForm.details.field2 = "Norris";
contentTypeManager.Update(newmem);
I get the error "Object reference not set to an instance of an object." for that first assignment line. What am I missing?
I am having trouble finding good documentation on ContentTypes for 8.0.1 now that the Ektron website has been redesigned.
Thx.
Thanks for clarifying, to ADD content to a folder that has a smartform assigned to it, the basic code block should get you started: (Note: the Html attribute of the content is simply the xml matched to the schema you created)
Ektron.Cms.Framework.Content.ContentManager cmanager = new Cms.Framework.Content.ContentManager();
Ektron.Cms.ContentData cdata = new ContentData();
cdata.FolderId = 0;
cdata.XmlConfiguration.Id = 0; //SMARTFORM ID HERE
cdata.Html = "<root><field1>field1 value</field1><field2>field2 value</field2></root>";
cmanager.Add(cdata);
You could update ContentTypes.cs to include an Add method. Just copy the Update method and change contentManager.Update to contentManager.Add.
public void Add(ContentType<T> contentType)
{
Initialize();
contentType.Content.Html = Ektron.Cms.EkXml.Serialize(typeof(T), contentType.SmartForm);
contentManager.Add(contentType.Content);
}
Unfortunately, contentManager.Add returns void. Ideally it should return the new content ID.
The ExamVersion class has an int? property named SourceSafeVersionNum
When I execute the following code:
var query = from examVersion in db.ExamVersions
where examVersion.ExamVersionID == ExamVersionID
select examVersion;
foreach (ExamVersion examVer in query.ToList())
{
yield return examVer;
}
examVer.SourceSafeVersionNum is set to 1 even though it is NULL in the database.
When I run the SQL code generated by LINQ in SQL Server, the SourceSafeVersionNum column value is NULL (as I'd expect) but in the foreach loop the examVer.SourceSafeVersionNum is 1.
I can't find anywhere in the code where a default value is assigned or any similar logic.
Any ideas why/where this value is being set to 1?
Here is the property declaration (generated by a .dbml file)
[Column(Storage="_SourceSafeVersionNum", DbType="Int", UpdateCheck=UpdateCheck.Never)]
public System.Nullable<int> SourceSafeVersionNum
{
get
{
return this._SourceSafeVersionNum;
}
set
{
if ((this._SourceSafeVersionNum != value))
{
this.OnSourceSafeVersionNumChanging(value);
this.SendPropertyChanging();
this._SourceSafeVersionNum = value;
this.SendPropertyChanged("SourceSafeVersionNum");
this.OnSourceSafeVersionNumChanged();
}
}
}
Have you tried setting a breakpoint in the set{} method of the property to see what else might be populating its value? You might catch the culprit in the act, then look at the Call Stack to see who it is.
As a follow up to this, here is what happened:
The code that retrieved the value from the database was being called twice but through two different code paths. The code path that was assigning the value of 1 was being stepped over by the debugger so I didn't see it.
In the dbml designer I've set Update Check to Never on all properties. But i still get an exception when doing Attach: "An attempt has been made to Attach or Add an entity that is not new, perhaps having been loaded from another DataContext. This is not supported." This approach seems to have worked for others on here, but there must be something I've missed.
using(TheDataContext dc = new TheDataContext())
{
test = dc.Members.FirstOrDefault(m => m.fltId == 1);
}
test.Name = "test2";
using(TheDataContext dc = new TheDataContext())
{
dc.Members.Attach(test, true);
dc.SubmitChanges();
}
The error message says exactly what is going wrong: You are trying to attach an object that has been loaded from another DataContext, in your case from another instance of the DataContext. Dont dispose your DataContext (at the end of the using statement it gets disposed) before you change values and submit the changes. This should work (all in one using statement). I just saw you want to attach the object again to the members collection, but it is already in there. No need to do that, this should work just as well:
using(TheDataContext dc = new TheDataContext())
{
var test = dc.Members.FirstOrDefault(m => m.fltId == 1);
test.Name = "test2";
dc.SubmitChanges();
}
Just change the value and submit the changes.
Latest Update:
(Removed all previous 3 updates)
My previous solution (removed it again from this post), found here is dangerous. I just read this on a MSDN article:
"Only call the Attach methods on new
or deserialized entities. The only way
for an entity to be detached from its
original data context is for it to be
serialized. If you try to attach an
undetached entity to a new data
context, and that entity still has
deferred loaders from its previous
data context, LINQ to SQL will thrown
an exception. An entity with deferred
loaders from two different data
contexts could cause unwanted results
when you perform insert, update, and
delete operations on that entity. For
more information about deferred
loaders, see Deferred versus Immediate
Loading (LINQ to SQL)."
Use this instead:
// Get the object the first time by some id
using(TheDataContext dc = new TheDataContext())
{
test = dc.Members.FirstOrDefault(m => m.fltId == 1);
}
// Somewhere else in the program
test.Name = "test2";
// Again somewhere else
using(TheDataContext dc = new TheDataContext())
{
// Get the db row with the id of the 'test' object
Member modifiedMember = new Member()
{
Id = test.Id,
Name = test.Name,
Field2 = test.Field2,
Field3 = test.Field3,
Field4 = test.Field4
};
dc.Members.Attach(modifiedMember, true);
dc.SubmitChanges();
}
After having copied the object, all references are detached, and all event handlers (deferred loading from db) are not connected to the new object. Just the value fields are copied to the new object, that can now be savely attached to the members table. Additionally you do not have to query the db for a second time with this solution.
It is possible to attach entities from another datacontext.
The only thing that needs to be added to code in the first post is this:
dc.DeferredLoadingEnabled = false
But this is a drawback since deferred loading is very useful. I read somewhere on this page that another solution would be to set the Update Check on all properties to Never. This text says the same: http://complexitykills.blogspot.com/2008/03/disconnected-linq-to-sql-tips-part-1.html
But I can't get it to work even after setting the Update Check to Never.
This is a function in my Repository class which I use to update entities
protected void Attach(TEntity entity)
{
try
{
_dataContext.GetTable<TEntity>().Attach(entity);
_dataContext.Refresh(RefreshMode.KeepCurrentValues, entity);
}
catch (DuplicateKeyException ex) //Data context knows about this entity so just update values
{
_dataContext.Refresh(RefreshMode.KeepCurrentValues, entity);
}
}
Where TEntity is your DB Class and depending on you setup you might just want to do
_dataContext.Attach(entity);
