Plugin Using Matlab COM Automation Server...Error: 'Could Not Load Interop.MLApp'
Apr 26, 2010
My Problem: I am using Matlab COM Automation Server to call and execute matlab .m files from a VB.Net plugin for a CAD program called Rhino 3D. The code works flawlessly when set up as a simple Windows Application in Visual Studio, but when I insert it (and make the requisite reference) into my .Net plugin and test it in the CAD program I get the following error: "Could not load file or assembly 'Interop.MLApp, Version 1.0.0.0, culture=neutral, PublicKeyToken=null' or one of its dependencies. the system cannot find the file specified."
What I've Tried: I am baffled as to why this occurs, but I was able to contact the CAD program's technical support staff and they suggested that it has something to do with their DotNet SDK having trouble with references that are located far outside the CAD program directory. They didn't have any solutions so I tried playing around with copylocal and this made no difference. I tried using other COM libraries and the Open Office automation server works fine, although uses url's instead of requiring a reference. I also tested Excel, which does require a reference, and it returned the error: "retrieving the COM class factory for component with CLSID {...} failed due to the following error: 80040154." This may or may not be related to the issue with the Matlab COM reference, but I thought was worthwhile to share. Perhaps is there another way to reference Interop.MLApp?

Here's the user environment: Microsoft 2003 Web Server Microsoft Visual Studio.Net 2005 (VB.Net) Microsoft Office PowerPoint 2003 We are attempting to use Interop in a web service to update PowerPoint presentations. It worked great on my laptop, but when we migrated to the server, we encountered issues.Basically, it started taking 10 or more minutes to open up the presentation, which means we usually time out.

it works on 32bit and framework 4 - error: could not load file or assembly Interop.XXXX.dll Steps to reproduce:Create a new VB.Net winform project on a 64 bit system with framework 4 drop windows media player control on form. builds and runs fine. project references has two interops to temporary directory under obj folder copy if necessary the two interops to the build output path and delete the old project references and add new ones pointing to the interops in the output path build and run, everything is fine.ste the target frameowrk to 3.5 and repeat the whole process. the build fails.This is just a simple example of what I am seeing on a much mor complex project. It happens with all interops, not just WMP.

I am not an expert programmer and am just getting familiar with .NET office automation. I have two questions:
1. For me to create word documents from my code on a server, does word have to be installed on the server? My test server does not have word installed. Is there a way to have the code open word on the user's machine in this case?
2. I am trying out some code for creating word documents. It works fine on my machine. However, when I try to run it on server it gives me an error.. "Cannot create ActiveX component." Is this a permissions issue or related to the fact that the server does not have word installed?

I have been trying to find a way to link VB .Net and excel in real-time. Using the COM and IRTDServer I have been able to send data from VB .Net to excel live (basic RTD server client), but I have not been able to find a way for the client to then publish back to the server real time, i.e. a cell that is changing based on a number of variable to be published back to the server and out to other clients real time.

I have successfully automated a PowerPoint Metrics presentation with VB.Net. However, since there were many complicated calculations, it took quite some time to make the 120+ slide presentation - so I recently tried to revamp the application to be multi-threaded.

I'm in the process of trying to create a new appdomain to load plugin dll's, then unload the new appdomain so I can update the plugin dll's without having to exit the main application. There are many, many examples out there and it looks like it should be fairly straightforward, however I'm having a problem where the main application is loading the plugin dll's along with the new appdomain. Of course this is a problem because I cannot overwrite the plugin dll's if they live in the main appdomain. Based on the examples I've seen the code below should only load the plugin dll into the new appdomain, however for some reason it also loads into the main appdomain.
Dim oDomain As AppDomain = Nothing
Dim oSetup As New System.AppDomainSetup()
With oSetup

The IDPAPlugin interface is in a seperate project that both the plugin dll and the main application reference.

We have a VB 2005 program that reads data from a database and builds an Excel output file to be emailed. This works fine from my computer but when we put it on the server it fails on the Excel functionality.
The error is: Unhandled Exception: System.Runtim.InteropServices.COMException
Although Excel is not installed on the server we did also build a Setup program to install our program. It copies the Microsoft.Office.Interop.Excell.dll to the server folder with the exe.I thought the setup program should register the Excel DLL and the program should work even if the server does not have Office or Excel installed.

I've been following a codeproject article on using the interop forms toolkit (basically a way for developers to slowly upgrade their VB6 projects to .net by allowing .net components run in VB6)
[URL]
While the .NET form is working fine in all other testing projects and environments, I've found that the Form_load event is actually firing twice once it's in executing in the VB6 runtime.Not only annoying, its forcing my initialization code to execute twice (causing all kind of problems on the second run).

I have a program that reads data from excel.
I use:Imports Microsoft.Office.Interop as well as a Reference from the "COM" tab called "Microsoft Excel 11.0 Object Library"
I built my program then copied the .exe from the inDebug folder to a location on my company's server. I then double clicked the .exe and it ran as I expected it would.My boss then tried (from another computer) and he gets this error:See the end of this message for details on invoking just-in-time (JIT) debugging instead of this dialog box.

I'm trying to figure out some Excel automation. I have a form set up so the user can click on a label to open an Excel file (as a background process I guess) so the file isn't actually visible. Once they click on the "Convert to Count" button it will multiply all the values in Column B by 1,250 and put the output in Column C. Once it has finished this action, it makes the file visible so the user can choose to save it or not. Also, some users have Excel 2003 and some have 2007. Would it be possible to be able to load both xls and xlsx?[URL]..I must say I am very new with .NET and have a little bit of knowledge with VB6. I'm not sure where to even begin. I've looked up some ways to load an excel file but couldn't get it to work the way I need it to. Most of the ways I found were loading the file into a DataGridView. I don't want to use a DataGridView if I don't have to. Some of the files the users might be loading could have 10,000+ rows and that would take too long I think.

i have created a com class library with vb.net. i have registered the dll with regasm. Then i imported and used it to a vb6 project. I have noticed that if i unregister the library and register it again then i get the following error:
Runtime error '-2147024894 (80070002)': Automation error.
In order to make the library usable again, i have to rebuilt the library with different ClassId, InterfaceId, EventsId at the classes and then register the new dll.
PS: it also does the same thing if i overwrite the registered file with the same file or if i rename its folder and then rename it back to its previous name. Rebuid and re-registered is needed.
