I want to upgrade an ActiveX control from VB6 to VB.NET. I'm having trouble upgrading this code:

I am going to be taking up a new job as a VB.net developer. I have worked with C# for about 3years. I did mention to the interviewer that I haven't worked with VB.net, but he seemed to think that its easy to migrate from C# to Vb.net.
how I can prepare myself for this job? Any good books or websites on this area? How different is vb.net from C#?
I am thinking of migrating to VB 2008 from VB 6.0. What are the things to expect from VB 2008. Is still the same?
Im still Looking for a trial version of VB 2008.
I have been using COM+ components(using VB 6.0) in my existing web application developed using Asp/sql. I'm basically using COM+ to get the benefit of it's inbuilt Transaction Management feature which is useful when you are performing some set of actions across different databases simultaneously.Now I want to migrate my existing site to the .Net Framework.

View 1 RepliesI have a legacy VB6 ActiveX control used in IE to provide control of a parallel-port device from a browser application. I wrote this thing about five years ago; It's a pretty simple control, and it doesn't require a lot of maintenance. However, I've noticed that running the VB6 tools is becoming more and more painful over time, so I'm looking at the possibility of migrating this code to VB.net 2008.This thing is super-simple. It implements IObjectSafety and exposes a single public method, which we call using Javascript. The control has no UI other than a single box with a caption that displays its name and version number-- useful for troubleshooting deployment issues.
How would I create the equivalent in .net? Am I creating an applet? Or a .net Assembly? Any gotchas to look for as I try to make this transition?(I should make it clear here that I'm not either a VB6 programmer or a .net developer-- I've dabbled in this stuff but it isn't my area of expertise, so go easy on me).

View 1 Repliesis there a quick way to migrate a .Net 3.5 App written with VS 2008 back to VS 2005?
I'm really fed up with VS 2008 freezing every time I resize a Table.
I have some questions: 1) What's the learning curve for someone with good background in VB6? 2) what are the main advantages of VB.Net compared to VB6 and what will I be missing from VB6? 3) With VB.NET 2010 "ultimate" edition is it possible to make stand alone apps or they will be depending on net anyway even for the EXEs?

View 2 RepliesI have generated a component in Delphi 2007 Code Gear and I need to migrate it to .NET to be used by VB.NET platform.I generated an ActiveX dll but I have been told that only the declaration of the class is visible in .NET.Actually the component I have generated is inherited by another component of which I have only the .dcu files. My new component is exactly similar as the parent one except from that I have overridden the constructor create.I wonder why the .NET, although it accepted the component, it did not provide the inherited properties, methods etc.
View 1 RepliesI have an Access data base back end that contains only the tables that was created in the year 2005 (by someone no longer here so cannot answer much about past and I am not very familiar with Access). When I use SSMA 2005 for Access v4.0 to migrate to SQL 2005 a table with images (defined as OLE Object) the ones that appear in the Access table as bitmap will work fine, there are ones that appear in the Access table as "Microsoft Photo Editor 3.0 Photo" or "Picture" that will not. I set up a data source and used tableadapters in a VB Windows Form and used data binding by dragging the column from the data table and dropping it on a predefined picture box on the form (this basic method works fine for all the other columns in the table). I am using Visual Studio 2008.
The Access database is over 130 megs and we are migrating it to make it available across a network to multiple and sometimes distant sites. [Code] I have used all the extensions defined in Photo Editor and this .obd is just another one I have tried to see if that makes any difference. I tried moving the array to a variable defined as an Image and then moving that to the picture box and that failed too. [Code]

I have a suite of programs that currently store PDF files as BLOBs in a SQL Server database table. The purpose of this design is to take advantage of Adobe's PDF iFilter and Microsoft's Full-Text Search functionality to allow other modules of my suite to run queries against the contents of a PDF file.This has been a huge headache, however, resulting in databases that are gigantic and unwieldy. We have also run into problems getting the Adobe PDF iFilter to play nice at times. Further, re-creating the entire full-text index on an 80 GB database can take a looooooong time (when it works at all!).So, the new idea is to use the open source XPdf library to extract a copy of the textual contents from each PDF file, and instead of storing the entire BLOB, merely store that textual data for the full-text functionality. Then, instead of storing the whole PDF file in the database, it will be stored somewhere on the server's file system.My issue relates to that last bit, storing the file on the server's file system, and the subsequent serving of that file out to remote users. Currently, with the entire BLOB residing inside of SQL, it has been very simple (though not easy) to manipulate the BLOB from the server to the client and vice versa. Sending the files across the network in chunks worked out well, too. I'm not sure how to do what I want to do now, though. I'm thinking that it's not a good solution to simply make a network share where all of the PDF files are stored and let the remote user view them by issuing a: Process.Start("{remote file share}filename.pdf")What I would LIKE to do is the following:
1. A Search is run, and the end user selects a file for viewing.
2. The SQL Server knows where the file resides on the local file system.
3. Something (on the server) issues a command to create a temp copy of the file at a safe location that is shared over the network.
4. The client's program then opens the file using a web browser.
Advantages:
1. The main body of the PDF files are protected and hidden from the prying eyes of those who shouldn't see them.
2. PDF files with Fast Web View enabled will load in a linear fashion, improving user experience.
Drawbacks:
1. I don't know what the "something" is in #3 above.
2. I don't know what happens when a file type other than ".pdf" is the target of the URL in a web browser. I know simple image formats will just open, but what if the file is ".doc/x". What about any other file type? Is it the same as issuing a "Process.Start("") to the UNC path?
