Runtime Error '-2147024894 (80070002)': Automation Error
Jan 4, 2012
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.

I work for Southwire Company. We are owners and developers of a program called SAG10. It is set in VB6. When trying to run this program on Windows Vista, I get a runtime error 440. Not all installs on Vista behave this way. I have had multiple successes in installing and running SAG10 on Windows Vista. I have changed settings to mimic the successful runs and I still get this error. I have disabled the User Account Contro

I created a simple VB 6 executable that runs fine on my computer (Windows 7), but when I deploy it to another Windows 7 PC or a Windows 2003 server, I get the error:
"Runtime Error 430: Class does not support Automation or does not support expected interface".
The code
Private Sub cmdStart_Click()
Dim rstLogin As ADODB.Recordset
MsgBox ("Before first recordset")
Set rstLogin = New ADODB.Recordset
MsgBox ("After first recordset")
End Sub
The line that generates the error is " Set rstLogin = New ADODB.Recordset". I had a coworker compile it from his Windows 7 pc and run it on other machiens and it works fine. So I believe it's an issue with my pc config.

[URL] using this method results in a modal dialogue box which the user must manually close by pressing end or debug or the VBA (and consequently the VB) code will hang.I am unsure how to get the message box to close.

I am writing a WinForm app on Visual Studio .Net 2005 which will be a rudimentary "unit tester" for various MS Excel 2003 applications...basically, it will ensure the integrity of the VBA code which fires off in the event lifecycle of the workbook.As a test for a "unit test failure," I created a simple workbook which generates a runtime error at the Workbook_Open event in the VBA code (an intentionally placed out-of-index call to an array). I have no problem opening workbooks via the .Net WinForm using the Excel Object library. My problem is that the run-time error is not captured by the WinForm app -- instead, it throws the runtime error directly on the Excel thread which the WinForm app starts.Is there a way for the WinForm app leveraging office interop to catch that excel runtime exception?
I've tried encasing the call in a Try-Catch block using a general Exception a COMException (via the System.Runtime.InteropServices library) catch...I've also tried instantiating the workbook directly using CreateObject(sPath) and instantiating an Excel Application, then using that to open the workbook...all with the same results...instead of the .Net app catching the exception, the runtime error bubbles up directly to the Excel application.Is there any way, either on .Net or the VBA code, for the WinForm app to catch and handle an Excel run-time error?

I am having a problem with this code. I have used this code before on other apps and it works, but I don't have a clue as to what is going on here.
This is the whole event. I get a runtime error msg thats says "Syntax error(Missing Operator) in query expression"
I think this is Legacy SQL coding but I don't know how to make it better.

When I execute the code provided, Word 2010 opens and appears visible and then stops with an error: "COMException was unhandled". But if I execute the code line by line (F8), the code runs perfectly, that is Word 2010 opens, it is visible and the template is opened. The error fails (always) on the third line of code. What is going on and how might I fix it? [Code]

EXCEL-VBA opens a COM-DLL that -at one place- refers to a class from a another NET-DLL. When the COM-DLL tries to initialize an object from a class (in the NET-DLL) i get an error that the methode get_ContentTypeProperties has no implementation. (--> attached file contains message).
I never created the method get_ContentTypeProperties, nor is it part of the interface i'm using. When accessing the COM-DLL via another DLL, to workaround EXCEL-VBA, it works properly.

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've automated quite a bit with excel and every so often one of these really annoying glitches pops up.I'm using Office 2003, all with latest service packs and everything, and basically I usually end up creating a lot of applications which automate excel, processing database information and exporting it etc, etc, etc.
I currently have finalized this most recent export process, which exports a moderately sized table into excel for the user to work with, but I wanted to adjust the printing area appropriately.SO, I set the PrintArea to the A1:K47 string, I set the FittoPagesTall/Wide to 1 and the Orientation to Landscape, and all of this is perfectly functional from my 2008 .Net 3.5 application. But in the open application window of the file i'm automatically creating, the page divider lines still show 4 pages of data. Now, I said to myself, i know that in the Page Setup Dialog I can set "Fit to Page" and it automatically adjusts the zoom factor (scaling) to fit the print area onto 1x1 pages.
The only property in the WorkSheet.PageSetup that appears to do this is the ChartSize property, but when I step over that line in the Application I'm debugging, I get the Exception:"Unable to set the ChartSize property of the PageSetup class"Now the only thing i've seen online about this error from Microsoft says it could occur when a printer isn't installed. That is not the case here.
I further looked up in the property and it said something about only being applied to "Chart Sheets" but when I try to use the workbook.worksheets.add() method witht the Type set to xlChart I get a com object disconnected from RCW error.NOw, I can manually go into the Page Setup Properties for the Excel Worksheet, and set the "FIt to Page" there, so How can I forcibly automate this exact same process without having to open the Excel APplicaiton.

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?

I just converted my project over to 2010 from 2008. Everything seemed to be working fine (no errors came up). I ran the program and found no run time errors either. I then proceeded to update my program by adding user controls. These controls where already used by the program (through references), but were originally external. Due to issues with them not updating updating (no matter what I tried) I decided to build them directly into the project. This did not cause any issues at first, the program continued to run without errors or execptions. I replaced some of the old controls that referenced the external project with the new internal ones. The old ones were completely deleted first, and then the new ones (named same as the old ones to reduce programming errors...and yes I am sure the names are spelled EXACTLY the same) were added.
Now, the progam is throwing an exception during the variable declaration of a form I had been using with no errors: "Unable to cast object of type 'OldControl' to type 'NewControl'". I have run into cast exceptions before an am fairly good at solving whatever the problem is (usually a simple issue). Here is the kicker (actually 2 kickers)... First, NO LINES OF CODE HAVE BEEN CHANGED from when the program was working fine. I have basically changed out 'old_textbox' for 'new_textbox' in the graphical interface (and have given the new ones the old one's names) and made sure no errors came up (which didn't happen). Second, this exception is being raised on a line that has NOTHING to do with the old or new control: Public AllowCopiesMode as Boolean = False
I know that sharing code is usually helpful in situations like these, but I wouldn't know where to begin concidering where the execption is being thrown. If anyone knows if there is an issue with vb.net 2010 or a 'quirk' that rquires me the do something slightly different, please let me know. Out side of that I am completely lost

I have an old Visual Basic 6 project that was brought to my attention for updating. The project is a label program that reads an Access 2000 (so it's labeled) database. The labels the program prints has headers and such hardcoded in the code and all of the fields that are selected are pulled in from the database. All that needs to be done is to have the hardcoded labels changed and the program recompiled, sounds easy enough right? After attempting to debug the program the error in the title of this post is displayed.

I recently created a windows service that starts other applications that I use on windows startup. Basically this service is for virtual computers i use to test software and web sites. The service starts and stops just fine but when a custom made application actually is run within the service I get a .Net error in my event logs. Ive read up online and found that this is caused by an unhandled exception (As a result of this error in version 2.0 of the framework the application is killed.) so i added the correct handler and it didn't work. Then i found that another issue could be .net being corrupt so i uninstalled and reinstalled still no fix. I know theres an issue with one of my applications but i cant find were. I don't get any errors when i debug anyone know what i should do? [code]

I get this error in this code:

Call Main.createObjects
Call My_Control.requestStuff
End Sub
at the 'Call My_Control.requestStuff' line.The 'Main' module looks like this:Public My_Control As ControlObject

right before the line that gets me the error, x gets the correct value right before the error happens which means My_Control is definitely an object and is definitely not nothing.

I have created a dll using class library project in Visual Studio 2010. I want to access this dll in Excel using declare statement. I have declared my dll entry function with "public shared".
While executing my routine in excel VBA i receive a runtime error "Runtime error:453 cannot find dllentrypoint" I have never created a vb dll, so forgive me if I'm wrong. I am thinking that "shared" declaration isnt sufficient and should use a def file like with C/C++ dlls. I couldnt find the linker option in properties.

A VB5 program I wrote years ago stopped working and is now giving me this error:
Run-time error '380':Invalid property value
I cannot figure out what has changed, since I run that program almost daily. It was working fine, then stopped (without any changes to the program). I suspect I may have uninstalled something it uses, but cannot figure out what.When I open the VB5 IDE, I get an error saying:
'c:program filesdevstudiovbComct232.ocx' could not be loaded--Continue Loading Project?
If I say no, it does not load and I cannot see the source code.If I say yes, it does load and I can see the source code but I get weird compiler errors.
