AVIFIL32.dll issue: How to redirect/distribute a Windows system dll under Windows 7?

Posted By:      Posted Date: October 26, 2010    Points: 0   Category :WPF

Hello Everybody

We build a VB .Net 3.0 Application that is processing avi files via avifil32.dll. Our application was working previously until a new avifil32.dll has been released several weeks ago in a MS Security update (Here the error:" AVIFileOpen failed:AVIERR_FILEREAD").

So the fastest and easiest solution right now for me is to just distribute the compatible avifil32.dll with our application (in the app folder). Under Windows XP this is working properly (Windows takes the dll from the app folder and not from the system32 folder).

But under Windows 7 it always takes the incompatible avifil32.dll from the system32 folder. I tried to use a "MyApp.exe.local" folder, but this does not work.

So my question is, how can I distribute/redirect a system dll (like avifil32.dll) under Windows 7 with a .Net Application (without changing the current software code if possible)?

PS: Something about my skills: I am not the programmer in our group, I am the support manager, so I don't have a lot of software programming experience. I have spent a lot of time to figure out how the redirection of system dll's works, but I can't get a solution.

Thank you

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.

Windows Server 2003: Discover Improved System Info, New Kernel, Debugging, Security, and UI APIs


There's a lot to say about Windows Server 2003. First of all, it's the first operating system with built-in .NET Framework support, and it's the first 64-bit OS from Microsoft. But wait, there's more! There are lots of new features and APIs in this version as well. For instance, Windows Server 2003 features Hot Add Memory and a number of other arcane new tidbits. There are new APIs for handling threads, directories, and files, and new features like the low fragmentation heap for managing memory and system information. There's vectored exception handling and new UI APIs as well.OS internals expert Matt Pietrek takes a look at the additions he finds most interesting and useful so you'll have a good place to start when you dive into Windows Server 2003.

Windows Management Instrumentation: Create WMI Providers to Notify Applications of System Events


Windows Management Instrumentation (WMI) is based on an industry-wide standard for notifications used to manage objects and devices across a network. By receiving WMI events, an application can be notified of changes to data in WMI itself. This allows the developer to notify the consuming application that certain system configuration data has changed, without the application having to poll WMI continuously for this data. The author presents an explanation of the different types of events in WMI, then goes on to develop an event provider.

The VTrace Tool: Building a System Tracer for Windows NT and Windows 2000


This article describes the techniques used to construct VTrace, a system tracer for Windows NT and Windows 2000. VTrace collects data about processes, threads, messages, disk operations, network operations, and devices. The technique uses a DLL loaded into the address space of every process to intercept Win32 system calls; establishes hook functions for Windows NT kernel system calls; modifies the context switch code in memory to log context switches; and uses device filters to log accesses to devices.

A first chance exception of type 'System.ArgumentException' occurred in System.Windows.Forms.dll

I've read a bit about this error and maybe I have nothing to worry about.  BUT ... my simple little app gets 7 of these before it even gets to the first Dim statement in the Class Form1!  I found and followed instructions on how to have the Debugger intercept these exceptions but it seems that they are not being intercepted.  I only know that they have happened because of the messages in the Immediate Window.  In the Designer all I have is 5 Labels and 5 TextBoxes.   Any thoughts on how I could get to the cause of these messages? Thanks,  Bob

Help!!!! Permission issue with Analysis Services on Windows 2008 R2

Hi I'm with a project using Sql Server 2008 on Windows Server 2008 R2. It seems I can not connect to Analysis Services server with SA acount but only with Windows Authentication (The 'Authentication' option is diabled). And when I connect to Analysis Services with my windows acount , I do not have the permission to either create a database (ERROR:Either '***' user does not have the permission to create a new object, or the object does not exist) or grant server privilege to my windows account (ERROR: Only an administrator can make changes to server properties). Also, I failed to remote connect to Analysis Services on Server with my windows account (But I can remote connect to Database engine). Any idea?  Thanks!
