Sharepoint Timer Job debuggging unable to set the Breakpoint - sharepoint-2010

I have a little problem. I'm trying to add a timer job following this tutorial : http://dotnetfinder.wordpress.com/2010/07/24/creatingcustomsharepointtimerjob2010/
I came to the point where my timer job is enabled and is launching every five minutes.
The problem is that it doesn't execute all the Execute method.
public override void Execute(Guid contentDbId)
{
// get a reference to the current site collection's content database
SPWebApplication webApplication = this.Parent as SPWebApplication;
SPContentDatabase contentDb = webApplication.ContentDatabases[contentDbId];
// get a reference to the "ListTimerJob" list in the RootWeb of the first site collection in the content database
SPList Listjob = contentDb.Sites[0].RootWeb.Lists["Liens"];
// create a new list Item, set the Title to the current day/time, and update the item
SPListItem newList = Listjob.Items.Add();
//newList["URL"] = "http://"+DateTime.Now.ToString()+".fr";
//newList.Update();
}
I attached the debugger to the OWSTIMER.EXE.
If i try to add a breakpoint at the line : SPList ListJob = ..., it's ok,
But if i try to add a new breakpoint at the next line (SPListItem newList = ...) then i have the following message :
"The following breakpoint cannot be set : ...
The CLR was unable to set the breakpoint".
Does anyone has any idea how i can make it work ?

You seem to be attaching to the correct service. See How to: Debug a Timer Job to double check your steps.
Also, as pointed out in this comment, you should restart the timer service when deploying a timer job:

There is a very important step that
needs to be completed with any Timer Project. You hav to recycle the
SharPoint timer service in between deployments. Best way to do this is
to add
net stop SPTimerV4 – Pre Build
net start SPTimerV4 – Post Build
to your sharepoint project. If you do not do the above – you will be
puzzled as to why your code seems not to be up to date. The reason is
that the timer service Caches the assembly with your class. This can
cost you hours of troubleshooting, in trying to identify why your code
does not deploy.

Make sure your project configuration is in Debug mode (in Release mode compiler is setting is enabled for optimized code). Refer to this blog post

Polarion API: How to update multiple work items in the same action

I created a script which updates work items in a polarion document. However, right now each workitem update is a single save. But my script updates all work items in the document, which results in a large number of save actions in the api and thus a large set of clutter in the history.
If you edit a polarion document yourself, it will update all workitems.
Is it possible to do this same thing with the polarion API?
I tried
Using the tracker service to update work items. This only allows a single work item to be updated.
Using the web development tools to try and get information from the API. This seems to use a UniversalService for which no documentation is available at the API site https://almdemo.polarion.com/polarion/sdk/index.html
Update 1:
I am using the python polarion package to update the workitems.Python polarion Based on the answer by #boaz I tried the following code:
project = client.getProject(project_name)
doc = project.getDocument(document_location)
workitems = doc.getWorkitems()
session_service = client.getService("Session")
tracker_service = client.getService("Tracker")
session_service.beginTransaction()
for workitem in workitems:
workitem.description = workitem._polarion.TextType(
content=str(datetime.datetime.now()), type='text/html', contentLossy=False)
update_list = {
"uri": workitem.uri,
"description": workitem.description
}
tracker_service.updateWorkItem(update_list)
session_service.endTransaction(False)
The login step that #boaz indicated is done in the backend (See: https://github.com/jesper-raemaekers/python-polarion/blob/3e61527cf0f1f3c8614a30289a0a3409d2d8712d/polarion/polarion.py#L103)
However, this gives the following Java exception:
java.lang.RuntimeException: java.lang.NullPointerException
Update 2
There seems to be an issue with the session. If I call the following code:
session_service.logIn(user, password)
print(session_service.hasSubject())
it prints False.
The same thing happens when using the transaction:
session_service.beginTransaction()
print(session_service.transactionExists())
also prints False
Try wrapping your changes in a SessionWebService transaction, see JavaDoc:
sessionService = factory.getSessionService();
sessionService.logIn(prop.getProperty("user"),
prop.getProperty("passwd"));
sessionService.beginTransaction();
// ...
// your changes
// ...
sessionService.endTransaction(false);
sessionService.endSession();
As shown in the example in Polarion/polarion/SDK/examples/com.polarion.example.importer.
This will commit all your changes in one single SVN commit.

How to update UI from a new thread vb.NET website

My application works like this:
Upload Excel file + convert to DataTable
Start new thread
Begin loop through DataTable
Update UI (Label) to show "Processing row [i] of [n]"
Next
End loop
The bold is what I'm not able to do. I've looked around online for updating UI elements from worker threads, but all the results I can seem to find are for Windows Forms, rather than a web project. Is this possible?
yes, you can do it, and actually it is not difficult. you can use ajax toolbox to do it easily. simply use an updatepanel, and update progress.
check http://ajaxcontroltoolkit.codeplex.com/
an example: http://www.asp.net/ajax/documentation/live/overview/updateprogressoverview.aspx
I found a workaround using jQuery AJAX and asp.NET WebMethods and a session variable.
I used a method from one of my previous questions, by having a WebMethod check on a Session variable that was updated by the worker thread.
Worker thread:
Session["progress"] = "{\"current\":" + (i + 1) + ", \"total\":" + dt.Rows.Count + "}"
WebMethod:
[WebMethod]
public static string GetProgress()
if (HttpContext.Current.Session["progress"] == null) {
return "{\"current\":1,\"total\":1}";
} else {
return HttpContext.Current.Session["progress"];
}
}
my jQuery basically looped calling that AJAX WebMethod every second. It would start on page load and if the current = total then it would display "Completed" and clear the loop, otherwise it shows "Processing row [current] of [total]". I even added a jQuery UI Progressbar
This is kind of a manual solution but it solves my problem, with little overhead. An unexpected but nice piece is that since it is utilizing a Session variable, and the WebMethod checks on page load, if the worker thread is active then the progressbar will show even if you navigate away and come back to the page.

How would I implement multithreading in this situation? Is it possible?

I have a form with a listview in it that the user can add tasks too. Then the user can click a button then the application goes through each task in the listview 1 by 1 an executes it.
These tasks are more like instructions that actually complete tasks.I do this by having a class with a loop in it that goes through each item and it then completes a task I set for each item(instruction). In order to start the parsing I have a button on a form that calls that function. IE: RunTask(listview1, 1) - basically all this does it starts the loop I have in my class , with a specified listview and which item to start on.
Everything works perfect except the screen locks up, so I cannot implement a stop feature to stop the application from parsing these listview items. I just don't understand how I can implement this without crossthreading, since the thread that I would like to run seperate will always access this listview. It is not feasable to redesign the program to get rid of the listview. I tried application.doevents although it caused way too man bugs. I have been researching for days on how to fix this but I have NO idea. Hopefully someone cans hed some light.
Also I had already added a background worker to solve the issue, although I had to obviously set checkforillegalcrossthreadcalls = false and I know this isn't smart.
Try doing something like this. Take you list view and turn it into a set of values that aren't UI related. Like this:
string[] values =
this
.listView1
.Items
.Cast<ListViewItem>()
.Select(x => x.Text)
.ToArray();
Then you can use the parallel task library to run your task in the background:
var tokenSource = new System.Threading.CancellationTokenSource();
var token = tokenSource.Token;
var task = System.Threading.Tasks.Task.Factory
.StartNew(() => RunTasks(values, 1), token);
If you need to cancel the task you can do this:
tokenSource.Cancel();
But to handle UI updates when the task is finished do this:
task.ContinueWith(r =>
{
/* When compete code */
});
Make sure that you invoke the UI updates so that they go on the UI thread.
My apologies that I didn't write this in VB.NET. My VB is getting rusty.

Ninject: More than one matching bindings are available

I have a dependency with parameters constructor. When I call the action more than 1x, it show this error:
Error activating IValidationPurchaseService
More than one matching bindings are available.
Activation path:
1) Request for IValidationPurchaseService
Suggestions:
1) Ensure that you have defined a binding for IValidationPurchaseService only once.
public ActionResult Detalhes(string regionUrl, string discountUrl, DetalhesModel detalhesModel)
{
var validationPurchaseDTO = new ValidationPurchaseDTO {...}
KernelFactory.Kernel.Bind<IValidationPurchaseService>().To<ValidationPurchaseService>()
.WithConstructorArgument("validationPurchaseDTO", validationPurchaseDTO)
.WithConstructorArgument("confirmPayment", true);
this.ValidationPurchaseService = KernelFactory.Kernel.Get<IValidationPurchaseService>();
...
}
I'm not sure what are you trying to achieve by the code you cited. The error is raised because you bind the same service more than once, so when you are trying to resolve it it can't choose one (identical) binding over another. This is not how DI Container is supposed to be operated. In your example you are not getting advantage of your DI at all. You can replace your code:
KernelFactory.Kernel.Bind<IValidationPurchaseService>().To<ValidationPurchaseService>()
.WithConstructorArgument("validationPurchaseDTO", validationPurchaseDTO)
.WithConstructorArgument("confirmPayment", true);
this.ValidationPurchaseService = KernelFactory.Kernel.Get<IValidationPurchaseService>();
With this:
this.ValidationPurchaseService = new ValidationPurchaseService(validationPurchaseDTO:validationPurchaseDTO, confirmPayment:true)
If you could explain what you are trying to achieve by using ninject in this scenario the community will be able to assist further.
Your KernelFactory probably returns the same kernel (singleton) on each successive call to the controller. Which is why you add a similar binding every time you hit the URL that activates this controller. So it probably works the first time and starts failing after the second time.

SPWeb.GetListItem COMException on first call - second is ok

I'm trying to use SPWeb.GetListItem() to get an item by a known URL (MSDN).
So basically I'm doing the following:
using (SPSite spSite = SPContext.Current.Site)
{
using (SPWeb spWeb = spSite.RootWeb)
{
SPListItem spListItem = spWeb.GetListItem
("/sites/testSite/Lists/testList/Folder/Subfolder");
}
}
in case you are wondering, I'm trying to get the folder "Subfolder" to do stuff with it.
The problem is that the first time I call this, I get a COMExpeption:
Cannot complete this action.
Please try
again.<nativehr>0x80004005</nativehr><nativestack></nativestack>
Description: An unhandled exception
occurred during the execution of the
current web request. Please review the
stack trace for more information about
the error and where it originated in
the code.
Exception Details:
System.Runtime.InteropServices.COMException:
Cannot complete this action.
There are some reports about the COMException happening because you need to use the full relative site URL, so instead of /Lists/testList/Folder/SubFolder, you need to use /sites/testSite/Lists/... - I'm doing just that. I also tried using the absolute URL (http://sharepoint/sites/...). The problem remains: I get the COMException when trying to get the spListItem for the first time.
When I try to run the code again after the Exception, the SPListItem is received just fine. Also all subsequent calls work - only the first one fails.
AmI doing some initializing wrong or something like that?
Perhaps try SPWeb.GetFolder() instead... but again it depends on what exactly you want to do with the Folder. Seems strange though that you're using a method used for getting list items on a Folder.
http://msdn.microsoft.com/en-us/library/ms461547.aspx
Try to instantiate the web where the list item is located - _uiserWeb.
I tryed Site.RootWeb.GetListItem(item_url) - it gave me null first time after code redeployment and was fine second time.
_item = _userWeb.GetListItem(item_url)
