View 12 RepliesI 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.
How do we automate the process of deriving an Interface from our already-designed class?In other words, I wrote in completion my entire class and now desire to automatically construct its interface. EG: Say my class's filename is "Car.vb", I now desire "ICar.vb" derived from the class "Car" that I've written.

View 1 RepliesThe software company I work for offers data conversion as a service for new clients who have previously used other similar software. I've written a VB.NET application to automate common conversion operations, and have separate logic between known vendors.particular file layout has become rather common, but due to the nature of how this particular competitor's application stores information, certain fields mean one thing for one client, and another for a different client.Certain elements within this vendor's format change every time, so I've written the application to account for that. Because some data fields mean different things to different vendors, I have to change my mapping code every time. This wasn't an issue when I had one of these every six months or so, but these are becoming much more common and I would much rather find a way to further automate this process.

I have a VB 2008 Forms application which does Powerpoint automation -- I am opening owerpoint in a minimized window from within my app and am trying to periodically put update messages in a textbox on my main form while the automation is running (it takes a few minutes to complete), but my form window does not want to show these messages until the powerpoint operations are finished. It seems as if I need to force a window refresh or something on my windows form, but I'm unclear how to do that. Below is some code that I'm using that illustrates what I'm trying to do. When I run it, "Step One / Step Two / Step Three" do not show up on my textbox until after the Powerpoint automations are over.

View 2 RepliesI 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.
