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).

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...
}
}
I have a console application which is runs as a Windows Task.
One of the actions done is to add a computer to an AD group.
The code below does that:
public static bool AddToGroup(string machineName, string groupName)
{
using (
var context = new PrincipalContext(
ContextType.Domain,
Helper.GetAppSetting("Domain"),
Helper.GetAppSetting("ServiceAccountLogonName"),
Helper.GetAppSetting("ServiceAccountPassword")))
{
using (var group = GroupPrincipal.FindByIdentity(context, groupName))
{
using (var computer = ComputerPrincipal.FindByIdentity(context, machineName))
{
if (group == null || computer == null)
{
return false;
}
group.Members.Add(computer);
group.Save();
return true;
}
}
}
}
This function and the task have been running without an issue.
This task failed once with the following error message: Exception of
type 'System.OutOfMemoryException' was thrown.
Is it because of the of the machine or group which is being searched for?
Is there an issue in the code as it is which makes it susceptible to OutOfMemoryExceptions?
I found the issue on the computer.
The paging file on the drive where the executable was running was set to None.
I am open to hear other possible issues here
I am trying to get a list of all users in our instance of Desire2Learn using a looping structure through the bookmarks however for some reason it continuously loops and doesn't return. When I debug it it is showing massive amounts of users (far more than we have in the system as shown by the User Management Tool. A portion of my code is here:
public async Task<List<UserData>> GetAllUsers(int pages = 0)
{
//List<UserData> users = new List<UserData>();
HashSet<UserData> users = new HashSet<UserData>();
int pageCount = 0;
bool getMorePages = true;
var response = await Get<PagedResultSet<UserData>>("/d2l/api/lp/1.4/users/");
var qParams = new Dictionary<string, string>();
do
{
qParams["bookmark"] = response.PagingInfo.Bookmark;
//users = users.Concat(response.Items).ToList<UserData>();
users.UnionWith(response.Items);
response = await Get<PagedResultSet<UserData>>("/d2l/api/lp/1.4/users/", qParams);
if (pages != 0)
{
pageCount++;
if (pageCount >= pages)
{
getMorePages = false;
}
}
}
while (response.PagingInfo.HasMoreItems && getMorePages);
return users.ToList();
}
I originally was using the List container that is commented out but just switched to the HashSet to see if I could notice if duplicates where being added.
It's fairly simple, but for whatever reason it's not working. The Get<PagedResultSet<UserData>>() method simply wraps the HTTP request logic. We set the bookmark each time and send it on.
The User Management Tool indicates there are 39,695 users in the system. After running for just a couple of minutes and breaking on the UnionWith in the loop I'm showing that my set has 211,800 users.
What am I missing?
It appears that you’ve encountered a defect in this API. The next course of action is for you to have your institution’s Approved Support Contact open an Incident through the Desire2Learn Helpdesk. Please make mention in the Incident report that Sarah-Beth Bianchi is aware of the issue, and I will work with our Support team to direct this issue appropriately.
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.
I am creating accounts and setting properties on them using System.DirectoryServices.AccountManagement in .NET 4.5. One of the requirements is that the group membership (including Primary Group) be copied from a template account. The code includes the following:
foreach (var group in userPrincipal.GetGroups()) {
var groupPrincipal = (GroupPrincipal) #group;
if (groupPrincipal.Sid != templatePrimaryGroup.Sid) {
groupPrincipal.Members.Remove(userPrincipal);
groupPrincipal.Save();
}
}
This works about 90% of the time. The rest of the time, it fails with:
System.DirectoryServices.DirectoryServicesCOMException was
unhandled HResult=-2147016656 Message=There is no such object on
the server.
Source=System.DirectoryServices ErrorCode=-2147016656
ExtendedError=8333 ExtendedErrorMessage=0000208D: NameErr:
DSID-03100213, problem 2001 (NO_OBJECT), data 0, best match of:
'OU=Whatever,DC=domain,DC=local`
on the GetGroups call. My guess is that there is a race condition of some sort with the user not being fully created before I next go to access it. I know from diagnostic logging that I am going against the same domain controller each time (it's using the same PrincipalContext so that matches my expectation) so it's not a replication issue.
Is my guess accurate? Is there a good way to handle this? I could just throw in a Sleep but that seems like a cop-out at best and fragile at worst. So what is the right thing to do?
Try something like:
int maxWait = 120;
int cnt = 0;
bool usable = false;
while (usable == false && cnt < maxWait)
{
try
{
foreach (var group in userPrincipal.GetGroups())
{
var groupPrincipal = (GroupPrincipal)#group;
if (groupPrincipal.Sid != templatePrimaryGroup.Sid)
{
groupPrincipal.Members.Remove(userPrincipal);
groupPrincipal.Save();
}
}
usable = true;
break;
}
catch
{
System.Threading.Thread.Sleep(500);
}
}
if (usable)
//All okay
;
else
//Do something
;
This way you can try for "a while". If it works good, if not do something like log an error, so you can run a fix-it script later.
