Runtime Error - Class Does Not Support Automation

Aug 11, 2011

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.

If Compile A VB6 App On Win7 - ADODB.Connection Errors With "Class Does Not Support Automation Or Does Not Support Expected Interface"

Apr 28, 2011

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)

Runtime Error '-2147024894 (80070002)': Automation Error

Jan 4, 2012

i have created a com class library with 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.

Office Automation :: How To Catch An Excel Runtime Error From A WinForm

May 15, 2008

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?

Build A Class Structure To Support Two Threads?

Nov 8, 2009

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.

Office Automation :: VBA Using DLL Error - Methode Get_ContentTypeProperties Has No Implementation

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.

Add Interfaces To A Class Programmatically (at Runtime)

May 7, 2012

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


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.

Office Automation :: Error Creating Word Documents On Server

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?

Convert Class Runtime In CType In Second Parameter?

Mar 22, 2010

1. I have three classes. Now I want to know how do I convert object to my class runtime?

for example,
Dim obj as New Object
obj = CType( MyPassedObject, Class1 )

Now, in above code, MyPassedObject can be Class1 or Class2 or Class3 but it is passed as Object. So is there any way that I can convert into CType as per the type of that object, directly to that class? I mean, I can pass object name into parameter and write down CASE statement here to convert to that class but I do not want to write down Case statement for each of my class, so just want to know is it possible anyway?

I mean just for example, Can I do something like  obj = CType( MyPassedObject, GetObject('Class1') or any other way?

2. Now for this obj, I am getting properties runtime and setting values and then updating.

for example,

Dim PropertyInfo As Reflection.PropertyInfo() = obj.GetType.GetProperties()

Now, Will it work fine if obj has been declared as Object and then I typeCast it runtime and then I get properties and set its values. Will it work if obj's variable type is Object or it must be that class type itself.

Define The Base Class Of A Form At Runtime?

Apr 29, 2010

I'm developing a software that handles very specific regional standards. In one part of the country they have different standards for entering this data than they do in other parts of the country. In fact there are hundreds or thousands of possible configurations that would be best in various regions.

The solution I've come up with is to write a program that can load different control configurations with the supporting code to its main form at runtime. I do not know how to accomplish this. Would I use visual inheritance at runtime? Would I use a plugin system? I just need to potentially allow a power user to design thier own interface or to modify an existing interface to better suit thier needs.

Edit: Is there a way to define the base class of a form at runtime? Could I create user controls in a plugin and pass them in to the host program?

Office Automation :: Excel 2003 Automation With VB 2005 Express?

Apr 20, 2010

Ok basically what I need to do is the following:Read FirstExcelDoc (attached)For every row in that: Retrieve data from sql server db based on info in the Orange columns of FirstExcelDoc Let's say I retrieved data elements A, B, C, D, and E from sql server. Then I need to enter those same data elements A, B, and C in another excel spreadsheet (which has formulas etc) After inputing A, B, and C in that spreadsheet, read a couple of calculated fields and compare those results to data elements D and E retrieved originally from SQL Server DB. Finally, output the results in the Blue columns of the FirstExcelDoc spreadsheet for that row.Loop through and do the same thing for row 2 of the FirstExcelDoc and keep on until you see "END TEST" in the FirstExcelDoc.

I'm looking for a method of doing this efficiently. I have read several articles over the past few days as well as those from Mike R. but just need some direction to get started on this.To start of I'm looking for whether to read the entire FirstExcelDoc spreadsheet or just read the info for first policy number(2nd row) and process it and write out the blue column info for that row and then loop through and come back and read the second policy number (3rd row) etc... Please attach a code snippet for either way of reading the data.
