Loader lock issue.

Posted By:      Posted Date: May 22, 2011    Points: 0   Category :WPF

Hi, All:

I am writting a COM using native C++ (NON-CLR) and a simple TestApp (WPF/C#.net) to call the API functions in the COM.  everything works fine. (COM registered and run TestApp in debug/release build)

To debug my COM, I set the command to my TestApp.exe on Property Pages>Configuration Properties>Debugging Category>Command

I also set the Post-Build event to register this COM DLL.


It worked fine for a while, but recently I keep getting the following error

<mda:msg xmlns:mda="http://schemas.microsoft.com/CLR/2004/10/mda">
       Attempting managed execution inside OS Loader lock. Do not attempt to run
       managed code inside a DllMain or image initialization function since doing so
       can cause the application to hang.
  <mda:loaderLockMsg break="true"/>
TestApp.exe has triggered a breakpoint


I tried to copy all the DLLs to the same directory of TestApp.exe,  but no avail. I also uncheck the LoaderLock item in TestApp Project's Debug -> Exceptions -> Managed Debug Assistants, still no avail.

Searched on internet found a bhotfix for VS2005

IsapiModule Error 500 Issue


I am about exhausted trying to figure out this error:

HTTP Error 500.0 - Internal Server Error

Description: The page cannot be displayed because an internal server error has occurred.

Error Code: 0x8007007b

Notification: ExecuteRequestHandler

Module: IsapiModule

Requested URL: http://localhost:80/ReportServer

Physical Path: c:\Program Files\Microsoft SQL Server\MSSQL.2\Reporting Services\ReportServer

When I enable Failed Request Tracing Rules and view the log output I am supposing that the actual problem is in the 2nd call where there are 2 backslashes before the actual filename in the specified path:


CALL_ISAPI_EXTENSION DllName="C:\Windows\Microsoft.NET\Framework\v2.0.50727\\aspnet_isapi.dll"


MVC2 issue - Stuck. Trying to create a cms with nested partials


I am currently trying to display multiple items on a single page. I am not sure as to how to tackle this. What I have is a database table that has all the page data in. I have this run as a PagesController and this works fine. However what I would like to do is, if say the Products page is selected via the menu, I want to pull back not only the Products page html but also get all the products, and even be able to pull them through via category. I was trying to use a partial view, but I can't get it to work. The same would be for other pages, having partial views to display the other content, ie if Gallery is selected, the page html for Gallery shows and it then can push to a partial view that pulls all the gallery images from the gallery db table and so on. 

Maybe I am tackling this the wrong way. I have the pages stored in the db to allow for a CMS system I have setup. Maybe I need to use models for all the other items(Products, Gallery, Videos and such) and use the partial for the page html?

Any help would be greatly appreciated as I am confused.

User validation Issue in xlsx file

Multiple Paramatized Threading issue


I need the funcitonality to have two methods run concurrently of each other and the parent thread (aka the method that makes these two calls) to halt until BOTH are done. After the threads are done, I need to perform logic on the returns of the method, so it is essential for both of them to be complete before the parent thread continues. I have searched the internet and tried varous attacks, and I always come up with the same result, this being the parent thread continues operation after the first thread finishes, leaving the second thread running.  Can someone show me a quick example of how I can do this. I have tried checking states of the threads, halting the threads, but I always end up with the same thing. Any help would be great. Thanks.

Word Automation Issue in Windows Server 2008 Hosting



The problem I am posting here is that I was facing nearly 2 weeks around. Any body comes with this stuff please help.

Word Automation in sample ASP.NET(C#) application.

I am using Microsoft.Office.Inetrop.Word Assembly for automation. Here I am reading a XXX.dot template file and fill the contents with dynamic data.

When i am executing my code in localhost:someportnumber the automation is working fine and I could get expected result and when I am hosting in my inetmgr(Windows XP is my OS) it is also working fine.

But the problem is that when I am hosting in my production server(Windows Server 2008 Standard Edition) I am not able to perform automation and results in the following error.

Data: System.Collections.ListDictionaryInternal
Message: Word has encountered a problem.
Source: Microsoft Word

The code gets failed in the following line:

ApplicationClass wordApp = new Microsoft.Office.Interop.Word.ApplicationClass();

Document wordDoc = wordApp.Documents.Add(ref oTemplate, ref oFalse, ref oMissing, ref oMissing); // Error in this line

I cannot able to proceed further. Can anybody please help me in solving this issue?

Thank you.

With Regards,


If Statement Issue



This is very strange to me. I have spent 2hrs looking into this inside out , but dont seem to get it

I have an if statement that inserts data into the database. But i check to make sure the name is not entered twice. Now when the name is already in the db, then it should insert else put out a message saying its already in the db

My code works fine except that  when its not in the db, its inserts but still puts out the message that says "Name is already in use" Not sure if am not seeing something. But thought i did bring it to the forum. Here is my code...Pretty simple

Protected Sub btnAdd_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnAdd.Click

        Dim objConnection As SqlConnection
        Dim objCommand As SqlCommand
        Dim strSQLQuery1 As String


        ' If there's nothing to Add for then don't search
        ' o/w build our SQL Query and execute it.
        If String.IsNullOrEmpty(txtAdd.Text) Or Leadbank.SelectedValue = "000" Then

Concurrent Affairs: Build a Richer Thread Synchronization Lock


In my last column, I showed the various thread synchronization mechanisms employed by the Microsoft® . NET Framework (see Concurrent Affairs: Performance-Conscious Thread Synchronization). I then examined the performance characteristics of all these mechanisms and determined that the Interlocked methods performed the best because the calling thread never has to transition to kernel mode.

Memory Models: Understand the Impact of Low-Lock Techniques in Multithreaded Apps


Because the use of low-lock techniques in your application significantly increases the likelihood of introducing hard-to-find bugs, it is best to use them only when absolutely necessary. Here Vance Morrison demonstrates the limitations and subtleties low-lock techniques so that if you are forced to use them you have a better chance of using them correctly.

C++ Q&A: Performance Monitoring, Managed Extensions, and Lock Toolbars


In the June 2004 issue of MSDN®Magazine, I described a class called ShowTime that you can use to do simple performance monitoring for your app. ShowTime uses its constructor/destructor to record the start/stop times of its existence so you can instantiate it in a block of code like so: { ShowTime st(_T("Total time is:")); // some lengthy operation } .

Windows 2000 Loader: What Goes On Inside Windows 2000: Solving the Mysteries of the Loader


DLLs are a cornerstone of the Windows operating system. Every day they quietly perform their magic, while programmers take them for granted. But for anyone who's ever stopped to think about how the DLLs on their system are loaded by the operating system, the whole process can seem like a great mystery. This article explores DLL loading and exposes what really goes on inside the Windows 2000 loader. Knowing how DLLs are loaded and where, and how the loader keeps track of them really comes in handy when debugging your applications. Here that process is explained in detail.

Datalist with embedded Grid or List...Sub Totals issue with iteration


Let me see if one of you can assist with this one...


i have a similar situation, but mine does not use the selected item (item Command). Here is what the form is to do:


1. this is for an educational environment, so we use SID- NOT SSN's, but i use the SID as a filter in the subset as the grouping unique id.

2. I'm trying to inject a sub total row at the last line item of each SID (if more than one item in the report for that SID).

3. I'm looping thru the items in the Datalist Item Command with a for each (item i in Datalist2.Items).
