CRM 2011 :LINQ query not getting executed - c#

i implemented my first LINQ query to check for duplicate records while the user adds a new record but it is not getting fired
I am working on CRM2011 and i wrote the plugin using LINQ and registered it with Plugin Registration Tool
Below is my code
if (context.Depth == 1)
{
if (context.InputParameters.Contains("Target") &&
context.InputParameters["Target"] is Entity)
{
target =(Entity)context.InputParameters["Target"];
if (target != null)
{
householdname = target.GetAttributeValue<string>("mcg_HouseholdName");
}
}
OrganizationServiceContext orgcontext = new OrganizationServiceContext(service);
{
var query = (from c in orgcontext.CreateQuery<mcg_household>()
where c.mcg_HouseholdName == householdname
select c
);
List<mcg_household> householdlist = query.ToList<mcg_household>();
if (householdlist.Count > 0)
{
throw new InvalidPluginExecutionException("Record Already Exists!");
}
}
}
i think the problem is with getattribute because when i check it with some hardcoded value it runs. please tell me in what stage i should register this plugin and if there is anything wrong with the code.

If your code works with hardcoded example it is probably problem with stage of execution. You have to register your plugin step in Pre-Operation stage of execution and Synchronous mode. Check this article for details.
Also, check if "mcg_HouseholdName" is correct string.

Nopcommerce Update entity issue

Using NopCommerce 3.8, Visual Studio 2015 proff.
I have created a plugin that is responsible for making restful calls to my Web API that exposes a different DB to that of Nop.
The process is run via a nop Task, it successfully pulls the data back and i can step through and manipulate as i see fit, no issues so far.
Issue comes when i try to update a record on the product table, i perform the update... but nothing happens no change, no error.
I believe this is due to the Context having no idea about my newly instantiated product object, however I'm drawing a blank on what i need to do in relation to my particular example.
Similar questions usually reference a "model" object that is part of the parameter of the method call, "model" has the method ToEntity which seems to be the answer in similar question in stack.
However my example doesn't have the ToEntity class/method possibly because my parameter is actually a list of products. To Clarify here my code.
Method in RestClient.cs
public async Task<List<T>> GetAsync()
{
try
{
var httpClient = new HttpClient();
var json = await httpClient.GetStringAsync(ApiControllerURL);
var taskModels = JsonConvert.DeserializeObject<List<T>>(json);
return taskModels;
}
catch (Exception e)
{
return null;
}
}
Method in my Service Class
public async Task<List<MWProduct>> GetProductsAsync()
{
RestClient<MWProduct> restClient = new RestClient<MWProduct>(ApiConst.Products);
var productsList = await restClient.GetAsync();
InsertSyncProd(productsList.Select(x => x).ToList());
return productsList;
}
private void InsertSyncProd(List<MWProduct> inserted)
{
var model = inserted.Select(x =>
{
switch (x.AD_Action)
{
case "I":
//_productService.InsertProduct(row);
break;
case "U":
UpdateSyncProd(inserted);
.....
Then the method to bind and update
private void UpdateSyncProd(List<MWProduct> inserted)
{
var me = inserted.Select(x =>
{
var productEnt = _productRepos.Table.FirstOrDefault(ent => ent.Sku == x.Sku.ToString());
if(productEnt != null)
{
productEnt.Sku = x.Sku.ToString();
productEnt.ShortDescription = x.ShortDescription;
productEnt.FullDescription = x.FullDescription;
productEnt.Name = x.Name;
productEnt.Height = x.Pd_height != null ? Convert.ToDecimal(x.Pd_height) : 0;
productEnt.Width = x.Pd_width != null ? Convert.ToDecimal(x.Pd_width) : 0;
productEnt.Length = x.Pd_depth != null ? Convert.ToDecimal(x.Pd_depth) : 0;
productEnt.UpdatedOnUtc = DateTime.UtcNow;
}
//TODO: set to entity so context nows and can update
_productService.UpdateProduct(productEnt);
return productEnt;
});
}
So as you can see, I get the data and pass data through to certain method based on a result. From that list in the method I iterate over, and pull the the entity from the table, then update via the product service using that manipulated entity.
So what am I missing here, I'm sure its 1 step, and i think it may be either be because 1) The context still has no idea about the entity in question, or 2) Its Incorrect calls.
Summary
Update is not updating, possibly due to context having no knowledge OR my methodology is wrong. (probably both).
UPDATE:
I added some logger.inertlog all around my service, it runs through fine, all to the point of the call of update. But again I check the product and nothing has changed in the admin section.
plugin
I have provided the full source as i think maybe this has something to do with the rest of the code setup possibly?
UPDATE:
Added the following for testin on my execute method.
var myprod = _productRepos.GetById(4852);
myprod.ShortDescription = "db test";
productRepos.Update(myprod);
This successfully updates the product description. I moved my methods from my service into the task class but still no luck. The more i look at it the more im thinking that my async is killing off the db context somehow.
Turned of async and bound the getbyid to a new product, also removed the lambda for the switch and changed it to a foreach loop. Seems to finally update the results.
Cannot confirm if async is the culprit, currently the web api seems to be returning the same result even though the data has changed (some wierd caching by deafult in .net core? ) so im creating a new question for that.
UPDATE: It appears that the issue stems from poor debugging of async. Each instance I am trying to iterate over an await call, simply put im trying to iterate over a collection that technically may or may not be completed yet. And probably due to poor debugging, I was not aware.
So answer await your collection Then iterate after.

in app purchase issue in windows store app

I have created an app with in app purchase and tested it with CurrentAppSimulator and works fine but when i create the package for app it fails
This is my code for which i am creating package
public async System.Threading.Tasks.Task InAppInit()
{
var listing = await CurrentApp.LoadListingInformationAsync();
// Delux Unlock - Durable
var unlockFeatureDelux = listing.ProductListings.FirstOrDefault(p => p.Value.ProductId == "deluxe" && p.Value.ProductType == ProductType.Durable);
isDeluxPurchased = CurrentApp.LicenseInformation.ProductLicenses[unlockFeatureDelux.Value.ProductId].IsActive;
deluxProductID = unlockFeatureDelux.Value.ProductId;
// Standard Unlock - Durable
var unlockFeatureStandard = listing.ProductListings.FirstOrDefault(p => p.Value.ProductId == "standard" && p.Value.ProductType == ProductType.Durable);
isStarndardPurchased = CurrentApp.LicenseInformation.ProductLicenses[unlockFeatureStandard.Value.ProductId].IsActive;
standardProductID = unlockFeatureStandard.Value.ProductId;
}
I am calling this method OnLaunched in App.xaml.cs
Based on our discussion here is what I would do:
The LoadListingInformationAsync method uses internet and if the user does not have an internet connection then it will throw an exception. So I suggest to wrap this whole stuff into a try/ctach block
As we see the ProductListings does not contain any item. I don't know how this list is populated, but as long as your app is not in the store I would not be surprised when that list is empty (Maybe someone can help out here... but i did not find anything regarding this in the docs). So for this I would just simply check if the feature you need is in the list... With this your package will pass the test you mentioned and you can upload it. If the list is also empty when the package is installed via the store, then something with the IAP setting is wrong (but that is related to the store..)
And a general comment: Obviously this code is not complete... You need some code for purchasing the IAPs and here we only get the Ids.. (But I think you only pasted the relevant part anyway.)
So all this in code:
public async System.Threading.Tasks.Task InAppInit()
{
try
{
var listing = await CurrentApp.LoadListingInformationAsync();
if (listing.ProductListings.ContainsKey("deluxe"))
{
// Delux Unlock - Durable
var unlockFeatureDelux = listing.ProductListings.FirstOrDefault(p => p.Value.ProductId == "deluxe" && p.Value.ProductType == ProductType.Durable);
isDeluxPurchased = CurrentApp.LicenseInformation.ProductLicenses[unlockFeatureDelux.Value.ProductId].IsActive;
deluxProductID = unlockFeatureDelux.Value.ProductId;
}
else
{
//There is no deluxe IAP defined... so something with your IAP stuff is wrong...
}
if (listing.ProductListings.ContainsKey("standard"))
{
// Standard Unlock - Durable
var unlockFeatureStandard = listing.ProductListings.FirstOrDefault(p => p.Value.ProductId == "standard" && p.Value.ProductType == ProductType.Durable);
isStarndardPurchased = CurrentApp.LicenseInformation.ProductLicenses[unlockFeatureStandard.Value.ProductId].IsActive;
standardProductID = unlockFeatureStandard.Value.ProductId;
}
else
{
//same as for Delux
}
}
catch
{
//Show this on the UI...
}
}

How to use Clutch for debugging SQL statements executed by the Entity Framework?

I am very new to the Entity Framework. Tried to save an object and it fails with the message
error in saving entities which do not make foreign key properties available
As something wrong happens when EF tries writing to the database, I wanted to see the actual query it is trying to execute. I am not yet using EF 6, so I can't use context.Database.Log. Some search told me that there is a library called Clutch Diagnostics which will help me.
I installed it from NuGet and set it up as described in this blog post. Basically, it involved adding the methods
public void CommandFailed(DbTracingContext context)
{
Debug.WriteLine("\nFAILED\n " + context.Command.CommandText);
// or Trace.WriteLine("\nFAILED\n " + context.Command.CommandText);
}
public void CommandExecuted(DbTracingContext context)
{
Debug.WriteLine("\nExecuted\n " + context.Command.CommandText);
// or Trace.WriteLine("\nExecuted\n " + context.Command.CommandText);
}
to a class which implements the IDbTracingListener interface, and adding
// Enable Tracing queries
DbTracing.Enable();
// Adding the listener (implementation of IDbTracingListener)
DbTracing.AddListener(new DbTracingListener());
to the application start method in Global.asax.
I expected to now see the SQL queries in my Debug window. But instead I got
What am I doing wrong? Did I miss something? Are my expectations wrong? Is the debug output the wrong place to look for the query? Is the listener meant to work for saving objects to the database?
My method for saving to the database is very simple,
if (keyword.ExtractedKeywords_ID == 0)
{
context.ExtractedKeywords.Add(keyword);
}
else
{
ExtractedKeyword dbEntry = context.ExtractedKeywords.Find(keyword.ExtractedKeywords_ID);
if (dbEntry != null)
{
dbEntry.CorrectSpelling = keyword.CorrectSpelling;
dbEntry.Embryonen = keyword.Embryonen;
dbEntry.ExcelNumber = keyword.ExcelNumber;
dbEntry.IsCell = keyword.IsCell;
dbEntry.IsOrgan = keyword.IsOrgan;
dbEntry.IsRecombinase = keyword.IsRecombinase;
dbEntry.IsReporter = keyword.IsReporter;
dbEntry.IsResearchTopic = keyword.IsResearchTopic;
dbEntry.ModificationStatus = keyword.ModificationStatus;
dbEntry.OriginalSpelling = keyword.OriginalSpelling;
dbEntry.Synonym = keyword.Synonym;
}
}
context.SaveChanges();
I have only tried it with brand-new objects (the if part gets executed), because I don't yet have any entries in the database table for going into the else part.

SharePoint 2010 "unhandled win32 exception occurred in W3WP.EXE"

I am getting an win32 exception that I need help debugging. I have a SharePoint page that has a custom Web Part that when I browse to that page, I get the following message:
In w3wp.dmp the assembly instruction at ntdll!RtlReportCriticalFailure+62 in
C:\Windows\System32\ntdll.dll from Microsoft Corporation has caused an unknown
exception (0xc0000374) on thread 43
Unhandled exception at 0xHEX in w3wp.exe: 0xc0000374:
A heap has been corrupted
I don't really know where to begin debugging this issue and searching the internet has yielded very little results.
I have saved the DMP file and I've loaded it into the Debug Diagnostic Tool for analysis. I don't know what parts are most important, so if someone could tell me which sections I should post, I will post them.
Where I think the problem is:
I have narrowed down the location of where the problem might be. If I don't call these methods, I don't get the error. Is there something wrong with the way I'm accessing the TermStore?
private void GetTerms()
{
using (SPSite site = new SPSite(PhaseListUrl.Value))
{
var session = new TaxonomySession(site);
if (session.TermStores == null || session.TermStores.Count == 0) return;
OfficeDropdown.Items.Clear();
OfficeDropdown.Items.Add("");
var termStore = session
.TermStores
.FirstOrDefault(ts => ts.Groups.Any(g => g.Name == TaxonomyName.Value));
try
{
var group = termStore.Groups[TaxonomyName.Value];
foreach (var ts in group.TermSets)
{
if (!ts.IsAvailableForTagging) continue;
AddTerms(site, termStore, ts.Id, ts.Terms);
}
}
catch (NullReferenceException) { OfficeDropdown.Items.Add("ERROR: Check your Org Term Store Name"); }
catch (ArgumentOutOfRangeException) { OfficeDropdown.Items.Add("ERROR: Check your Org Term Store Name"); }
}
}
private void AddTerms(SPSite site, TermStore termStore, Guid tsId, TermCollection coll)
{
foreach (var t in coll)
{
if (t.IsAvailableForTagging)
{
var wssIds = TaxonomyField.GetWssIdsOfTerm(site, termStore.Id, tsId, t.Id, true, 1000);
if (wssIds.Length != 0)
{
var id = wssIds[0];
var validatedString = string.Format("{0};#{1}{2}{3}", id, t.Name, TaxonomyField.TaxonomyGuidLabelDelimiter, t.Id);
OfficeDropdown.Items.Add(new ListItem(t.Name, validatedString));
}
else
{
int id = -1;
var value = new TaxonomyFieldValue(SPContext.Current.Web.AvailableFields[new Guid("{a64c1f69-c0d6-421a-8c8a-9ef8f459d7a2}")]);
value.TermGuid = t.Id.ToString();
var dummy = value.ValidatedString;
if (dummy != null)
id = value.WssId;
var validatedString = string.Format("{0};#{1}{2}{3}", id, t.Name, TaxonomyField.TaxonomyGuidLabelDelimiter, t.Id);
OfficeDropdown.Items.Add(new ListItem(t.Name, validatedString));
}
}
AddTerms(site, termStore, tsId, t.Terms);
}
}
UPDATE:
The bug was in the TaxonomyField. I was accessing terms cross site collection and the IDs hadn't been generated. Also look out for TermStore IDs not being the same cross site collection (and know where you are calling from and where you are calling to!)
Here are some suggestions.
Pull up ULS Log Viewer and study the logs, if you hit the page and get that error, it should be logged there.
Check the application event logs on the web front-end server(s).
Have you also tried attaching to the W3P.exe process and debug the solution? (Assuming it's not the production environment of course).

SPListItem.Tasks always empty

I have a custom sharepoint (2007) list (named testlist) on which I attached a test workflow (built with sharepoint designer 2007 and named testwf), which only task defined in the 'Actions' section at 'Step 1' is to wait until april 2014.
When I add a new item to the testlist the testwf will start and, when I switch to the grid view, the item has the field "testwf" as running.
Now I need to access the workflow associated with the item and then "complete" this task via code by changing its status but, using the following code, I always get the item.Tasks list empty (but I can see that the internal variable m_allTaskListTasks has 1 element).
using (SPSite site = new SPSite("http://mysp"))
{
site.AllowUnsafeUpdates = true;
SPWeb web = site.OpenWeb();
web.AllowUnsafeUpdates = true;
foreach (SPList list in web.Lists)
{
if (list.Title != "testlist") continue;
foreach (SPListItem item in list.Items)
{
item.Web.AllowUnsafeUpdates = true;
if(item.Tasks.Count > 0)
//do work
}
}
}
Maybe I'm missing something...
I use this code to access my workflowtasks:
Guid taskWorkflowInstanceID = new Guid(item["WorkflowInstanceID"].ToString());
SPWorkflow workflow = item.Workflows[taskWorkflowInstanceID];
// now you can access the workflows tasks
SPTask task = workflow.Tasks[item.UniqueId];
Cross-posted question.
#petauro, have you made any headway on this? I can corroborate #moontear's answer based on the following code that I have used with success in the past:
...
// get workflow tasks for SPListItem object item
if (item != null && item.Workflows != null && item.Workflows.Count > 0)
{
try
{
var workflows = site.WorkflowManager.GetItemActiveWorkflows(item);
foreach (SPWorkflow workflow in workflows)
{
// match on some indentifiable attribute of your custom workflow
// the history list title is used below as an example
if (workflow.ParentAssociation.HistoryListTitle.Equals(Constants.WORKFLOW_HISTORY_LIST_TITLE))
{
var workflowTasks = workflow.Tasks;
if (workflowTasks != null && workflowTasks.Count > 0)
{
// do work on the tasks
}
}
}
}
catch
{
// handle error
}
}
...
While only slightly different from the code you posted in your latest comment, see if it helps.
Another minor point: are there multiple instances of lists titled "testlist" within your SPWeb? If not, why iterate over web.Lists? Just get the one list directly and avoid some superfluous CPU cycles: SPWeb.GetList()
You have to go differently about this. You need to get the workflow task list and retrieve your task from there and finish it.
First you would need to check whether a workflow is running on your item: if (item.Workflows > 0) from there you could iterate through all the workflow instances on the list item, get the SPWorkflowAssociation and the associated task and history list. From there you would only need to find the task you are looking for in the associated task list.
