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.

I compiled some VB6 code on my Win7 x64 machine and the result .exe will not run correctly on any other machine. VB6 code is just a new template .exe file with one button, a reference to "Microsoft ActiveX Data Objects 2.6 Library" and the following code in the button press event: Dim db Set db = New ADODB.Connection It runs correctly on my machine, but no others (even other Win7 x64 machines) (Update: I found TWO other users where it runs and one of them is Jeff Atwood!, but most machines have the same problem)
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:
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.
[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 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 have this application that users can make exams that contain exercises of different ... whatever. Anyway when student takes the exam he chooses it from a list and then all exercises are loaded from database. I wanted to make loading process faster by loading only first exercise data and putting others in background thread.
Actually in other parts of this application something like that is done but not by me. Basicaly an api class is built around BackgroudWorker and i can use this class to put certain functions of objects to be executed in background. The idea sounds great but in real life there are some problems with it. For example for historical reasons this application uses global functions and reader and uses global connection to Access database which means if in background something is being fectched from data base and you try to fetch from database in main thread then a „reader is already open" error occurs. To avoid this error if im doing something in main thread and want to fetch some data i have to move my function from main thread into background worker function list. And basically this in my opinion stinks cuz you end up with many delegātes, invoked checking and thre result... I was just thinking that there maybe is another way to allow (maybe with events) not put everything in background in case something is happening in bakcground but rather allow bgworker to finsih current thing, then do my thing and then resume bgWorker and not create havoc in code.
Basically i have to classes - exam and exercise that each implement many interfaces (like IExercise, IExerciseResult, IExerciseYesNo, IExerciseMultipleChoise etc.)And then i have DataBase classes like ExerciseDB, ExerciseResult etc. That have functions that preparē the sql params and call sqlHelper functions.And for example when i load up exam i go throug all exercises and call LoadData function that in turn calls ExerciseDB function selectData and then i put the returned data in Exercise object. And this type of thing of course would producē error if i at the same time would try to register the answer in database for another exercise. Ofcourse i could always check and put this in background... but as i said i'd rather want to work with database from both threads.

I am writing a small project which first reads all the access database's in a web directory and shows the database names in a combobox. When the user select one of the names, the system connects to the database in question (still in the web directory), and shows the database contents.I have tried the following code:
Imports System.IO
Dim NetFiles As String = "http://www.myWebsite.com/db/"
Private Sub LoadAllLanguage()[code]....
Problem is I get an error from the LoadAllLanguage function: 'does not support URL formats'

I am having a problem using ADO 2.8 and SQL Server 2000.Im using the SQLOLEDB Provider and when Im trying to set the Index by using the code below i receive the ffg error...Error 3251 : Current Provider does not support the necessary interface for Index functionality..I have to use SQL Server as our Access databases are quite large...Does the index and seek function even work with ADO and SQL Server 2000?...I am migrating from DAO to ADO to use SQL Server and Im trying not to change the existing code so I need to use the Index and Seek functionality as it has been used everywhere...There are no links between any tables so I am accessing the table directly.

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 looking for a way to add an interface implementation to a class at runtime. Here is a sample code, which I will discuss below.
Public Interface IAction Sub DoThis(a As Integer) End Interface
[Code]....
This is related to WCF, where one needs to provide to CreateHost a single class, which implements all interfaces required for the end points. In this scenario, ActionDispatcher is such a class, and IAction is one of the many interfaces to be implemented.
My vision is to avoid implementing IAction in ActionDispatcher manually, but have some sort of registration mechanism, where I can say, that ActionDispatcher must implement interfaces IAction, IDoing, INoAction, etc - and have the dispatching methods generated for me.
MSDN says, that any class is compatible with any interface, so I don't need to declare "Implements" in the ActionDispatcher. But I still need to implement the interface and connect the implementing method to the interface definition, so WCF can find it when needed.
The closest thing I found is probably the Automatic Interface Implementer, but it (1) creates a new type, (2) adds dummy methods.
I has also tried to understand CodeCompileUnit class, but so far couldn't see the relation to what I need.
I apologize if this is a rudimentry question, but I have an application that makes several calls to several .dll's. I notice that the first time the function is called, it seems to take a very long time (about 10 seconds) for the functions to complete.
