I have a current Windows VB6 application that needs converting to VB.NET. The application collects data from data acquisition instrumentation using RS232 and GPIB buses and stores the data in text files. The program was developed under Windows 95, 98 and Windows XP but continues to run under Windows 7 and 10. The application has communication problems on some installations in Windows 7 and 10 but not all. We cannot seem to troubleshoot in a Windows XP environment. We cannot install the VB6 environment in Windows 7 or 10. We have tried to convert the project from VB6 to VB.NET using the Microsoft process of VB6 to VB.NET 2008 Express to VS 2017. The process gave us a bunch of issues we are struggling to correct. We need help!

Hello, As for experience in VB6>VB.NET conversions, may I kindly refer you to two such of my projects: • https://www.freelancer.com/projects/NET/Need-migrate-application-based-Access/ • https://www.freelancer.com/projects/Software-Architecture/Conversi-reprogramaci-software-hecho/ This one is an ongoing big administrative and production system for a food industry. As for technical tools: • I've developed programs of my own to further automate features beyond basic conversion. • I have various packages of 3rd party VB6 components installed to assist me in testing the application, either pre- or post-conversion: Crystal Reports, Protoview ActiveX Suite, Codejock Xtreme Suite, Sheridan, etc. You may choose to replace them with native components. If we get to further discuss your project, I will ask for some metrics of your application, in order to more accurately assess time & budget. We can also agree on splitting the work into milestones if project scope merits. Looking forward to your contact, Grunty.

Hi.. I have many experience converting projects from VB6 to VB.Net using the VS 2008 converter. My last project was about to convert an Excel Addin made in VB6 to VB.Net. The final solution could be compiled in VS 2017. I have set a 5 days period for delivery but it will depend on the complexity of the project to be converted and if it uses third party dll's. Btw, I have installed VB6 in Win10, I can also help you with that.

Hi, I am a senior software developer in Australia. I have 20 years experience in VB and 10+ years in VB.NET. I have recently completed converting a VB6 application with 2.2million lines of code and 60 + forms to VB.NET, using the 2008 converter, then migrating the code to VS 2017. I have completed various VB.NET projects that interact with RS232 devices using the .NET SerialPort class, from barcode scanners to EFT devices. I am very familiar with migrating legacy VB RS232 code to the .NET SerialPort class. I would like more information regarding your project, whether there are any 3rd party controls, how many forms, classes, modules etc. I am very selective with the jobs I bid on but believe this task is a perfect match for my skillset. Freelancer prevents me from contacting you directly but I am happy to discuss further if you would like to initiate a 'Chat'. I am not going to be the cheapest bid, but I provide solid, fully documented code and will be available for future support if required. Cheers, Caleb.

Hello! I'm Bob and I'd like to help you convert your VB6 application. I am well experienced with both VB6 and VB.NET and I can handle the conversion. What type of errors did you get when attempted the conversion? How much of the code was covered flawlessly? How many errors you've count? I would provide more accurate estimations when I look into the code and get those answers :) Thank you for considering my application!

Hi, I am interested in your project and have couple of questions: - Does the current app connects to multiple DAQs at the same time - How complex is the VB6 app in terms of UI. What level of user interactions it allows or the app is doing most of it's work in the background - You mentioned IEEE-488 interface, what drivers are you currently using. Are they compatible with .NET - Any specific reason the app to be converted to VB.NET instead of C# .NET - Once the app is converted how do you suggest we do the testing. Please consider selecting me to work on this project Thank you, Stanislav

I'm a senior software developer with more than 25 years of experience on generating desktop applications for Microsoft operating systems. I worked with VB since the first versions (Quick Basic) to the actual VB.Net and with all Microsoft operating systems for desktop (from DOS, Windows 3.1, Windows 95 and above) and server (from Windows NT and above). I'm an electronic engineer too, so I know how work a serial communication, but I need more information about your issue. For example which type of instruments are you using and what type of communication error have you encountered. The conversion from VB6 to VB.Net is always a pain, for many software developed by me in VB6 I preferred to rewrite them from scratch instead to convert them to VB.Net and solve several hundred issues generated from the conversion procedure itself. If the software is not too much complicated we can rewrite it in VB.Net, this should solve the problem because the .Net Framework offers native access to the serial port and we can use managed code to avoid memory leakage and asynchronous procedures to obtain the right synchronization for threads, that in this type of applications are often the cause of issues. Feel free to contact me on chat, or send me a message to giro[.]freelancer[@]gmail[.]com (the address is mixed for security reason, remove all the square brackets). Regards

Hello, I specialize in building engineering, scientific and trading applications on a variety of platforms. I have completed nearly 150 projects here successfully. I read your requirements, I can convert your VB6 application to VB.NET (using .NET framework 4.5). It will support both 32-bit and 64-bit versions of Windows. I have converted many VB6 projects in the past. I have the following questions : 1) Do you have any simulator / emulator for testing RS-232 and G-PIB links ? If the protocol is known, I can use an emulator to test it on my end - this will save a lot of time and improve reliability. 2) I can also debug and test the VB6 application on Windows 10 (and debug using VB6 Enterprise Edition). 3) Does the program use any database(s) - e.g. MS Access etc ? I also suggest that you do not upload your VB6 or converted code unless you have discussions with shortlisted (3-4) developers. Your code may end up with strangers and competitors. Looking forward for more details from you, Regards, Adheer.
