Paid on delivery
Task is to convert a Visual Basic 6 program to Delphi (needs to compile with Delphi7). The program is used to communicate with a device through the serial port. It sends and receives characters. There is one timer interval that checks for a periodic string sent by the device to detect a "heartbeat". There is one serial receive interval that gets a character from the serial port and add it into a receive buffer. The program main form has multiple input fields. These fields are parsed and a configuration string for the device is created. Additionally there is an option to read data from the device. A second form is used to display the process. The data is formatted and then written to a file. Both the source as well as compiled exe is available. Support can be given on functions of the VB6 program.

Hello. I have large experience in converting code from one programming language to another programming language. I have installed both VB6 and Delphi 7. I am going to use step-by-step debugging in order to make sure new code works same as original code.

Hi, I am Delphi expert with more than 15 years of experience in various areas especially related to external devices communication, it's usually done through RS232 so I have a vast knowledge of serial protocol and how to avoid common mistakes while working with external devices. Can you tell me do you want app to be tested to work on your device or you want to make a 1 to 1 translation to Delphi and then you'll handle testing?

Hi! My name is Konstantin.I have a lot of experience in cross-platform and cross-language software porting. Also I have a lot of experience in serial port communications using different languages and APIs, so I think I can do this project fast and with high quality. But anyway time frame and price for porting project depends on existing software architecture, implemented functions, user interface complexity and many other things. Can you provide more details about this software? Screenshots, protocol description, etc.?

I have big experience with programming in Delphi and Visual Basic is also not unknown to me. I made hundreds of applications in Delphi of which many for communication over serial and parallel port with microcontrollers, programmers, sensors etc. I am sure this will be easy job for me so my bid is lowest possible.

Hi I'm a developer with more than 30 years of experience working with Delphi. I also have done a fair amount of work with VB 6. In the past I developed several applications to extract and configure data loggers (as part of a research work in which we attached these data loggers to a dolphin's dorsal fin). I'm sure I can help with your project. If you think you may be interested in my services,please send me a message, so I can provide my CV (for you to check references/experience) and we can further discuss your requirements. Best regards, Marco García

Hi, Your project sounds very interesting and I believe that I'll be able to perform the task perfectly. As for my experience, you can see for yourself that I've worked here mainly as a content and article writer; but, I've also done some VA work, which included a lot of both Excel and MS Word work as well as some Access and VBS tinkering. I've done some applications for controlling electrical devices using COM and LPT ports. You're welcome to check my reviews and should you have any questions, I'll be happy to answer. Kindest regards.

Hi, I'm senior Delphi developer here in the Philippines and have 7+years of experienced in developing extensive applications using Delphi. I also well experienced in vb6 so it should be easy for me to convert it to Delphi language. Also we can use TComport component to read the data sent by the device. Hoping for your response. Best regards, Rodel

Dear sir(s) / madam(s): I'm a software developer with 15+ years experience. I have worked with Visual Basic 6 and with Delphi since the years when version 6 was the latest. If it can be done, the software will be designed to compile and run on the most basic editions of Delphi 7, Standard or even Personal. Third party components will also be avoided whenever possible. As an alternative (of course if you approve it) I can develop the application using Lazarus/FreePascal. It's an Open Source, cross-platform alternative to Delphi. If all the communication is done via serial port and without requiring Windows-only drivers or features, the application could be easily ported to Linux and Mac OS X. Lazarus/FreePascal. I'm stipulating the time of delivery in two days on the sake of caution. But if the application could be completed on less time, it will be delivered as soon as it is finished. We can agree on a post-delivery test/bugfix period, during which I will be correcting possible bugs at no cost. I will also add new features if they aren't going to require a substantial rewrite of the code. Contact me if you require more details. Good luck with your project!

Dear Sir, I have experience writing communication programs in Delphi. I make several programs working on IEC 870-5-101, IEC 870-5-103 and other serial protocol. I can make it workin with state machine. In this way program will not be blocked if you disconnect serial port and you have control to stop an start it. Best regards Janez

I began using Delphi when Delphi 1 was released. From that I was working with Delphi and Embarcadero to current time. I was developing a lot of apps for accounting, ... and a lot of apps/drivers for device controlling (readers, electromechanic, gaming/gambling, ... devices). Via USB/RS232/.... You are needing a concrete (D7) version then I will have to search my SerialComm components for it (they are customized). I will need some time for installing D7 but in a few days I will be able to give you your app. Conditions: - You will must give me all specs and complete funtional cast by writting (doc). - I will not be earning your money until you have your app running (except FL commission which I will require inmediatly). I remain at your disposal. Regards Question: Are you needing a "threaded comm reading" or not?

Experienced in Delphi7 and VBA for >=10 years. I developed several Delphi apps which communicates with external app (MS Excel, Access and some others). I didn't communicate with serial port through Delpi app; however, I imagine how it can be done. We'll need tight comunication in order to debug app.

I have a lot of experience in programming RS-232 devices. I would like to suggest that you ship the device to me, as it is a lot easier (both for you and me) to debug and make 100% bullet proof protocol communication code when you have the device present. Please contact me if you have any questions.
