Motorola MC70 / Microsoft Windows Mobile 5.0 development question

Asked by: mychel_normandeau

Hello!

I must develop a small application for the Motorola MC70 device.

MC70 Handheld Mobile Computer
http://www.motorola.com/business/v/index.jsp?vgnextoid=d3da7b103d175110VgnVCM1000008406b00aRCRD

Memory: 64 MB (RAM)/128 MB (ROM) or 128 MB (RAM)/128 MB (ROM)
Operating system (OS): Microsoft Windows Mobile 5.0 Premium Phone Edition
Processor (CPU): Intel® XScale" 624 Mhz processor

The application must read a barcode, validate it through the Internet (MySql database) and then display the status.

I have no real experience with mobile devices... I have 10 years experience with Delphi and 4 years with C++. Since it seems it's not possible to develop for Microsoft Windows Mobile 5.0 with Delphi, I read that Lazarus can (www.lazarus.freepascal.org).

I know that mobile. .NET framework is the way to go, but I have 0 experience with Visual Studio and would like to stay in known territory for this project  if possible (time constraints).

Any advice/suggestions? Is it possible to do it on Lazarus?

I think the answer depends on how your're going to use the scanner. I'll explain what I mean.

you can use DataWedge/ScanWedge utility usually shipped with Symbol (or now Motorola) devices. It allows you scanning into any textbox without any programming effort from your side (except, maybe, the simple thing to recognize the end of the scanning - this can be achieved by configuring DataWedge to append some special symbol to the end of the barcode, so you can handle it in the application). So if you don't need to handle scanning from anywhere in your app then you can program in any language/IDE. If you do require scanner handling (which gives you more control and freedom) then you need SDK which is usually for C/C++ or CF.NET => hence you'd probably need Visual Studio to use it.

So if I were you I'd go with VS and CF.NET, but it depends on you entirely (you'd need to purchase VS20005/8 Standard Edition at least or perhaps use Mono IDE) and time available.

I agree with alexey, and I also would encourage you to choose one of the mainstream ways to develop for Windows Mobile (Visual Studio C#, VB.NET or C++), not Lazarus. I would not allow any of my projects to be developed in Pascal because it would immediately ensure that the project would require non-standard skillset, tools, and would probably be unsupportable in a commercial app. Choosing mainstream means you have a large community and a good company behind the product, and you have many sample at your fingertips for when you have to do something out of the ordinary.

For Delphi programmers, both C# and VB.NET are easy to learn. The .NET platform was developed in the same style, by some of the same architects from Borland.

I had a similar issue a while ago when I need a database application for windows mobile.

Since Delphi was my natural environment, I was wandering between Delphi, C++ (which was not my favorite and somehow hard to work with) and Lazarus. It is possible to make native Windows Mobile (Win CE) application with Lazarus although I never succeeded by myself.

After loosing tremendous amount of time on alternatives I finished working with Visual Studio 2005 and quite easily I made my app (thank you google). I had no previous VS2005 experience and the only knowledge about basic was my high school and VBA programing here and there. The final app was Compact Framework .Net 2.0 and it worked on my Pocket PC 2003, Windows Mobile 6.1 and desktop, too. I was quite amazed with that, either I needed to load different SQLite driver for the desktop.

So, if you still think how to do it. Use my experience. If you try alternatives you will have less documentation available, less third party drivers, components...

Hope it helped,
B.

Hi,

You can use Symbol Mobility Development Kit v1.6 for .Net(this is what i am using for .net CF). Symbol is providing API for barcode scanner(Symbol.Barcode namespace). You suppose to enable all or needed DecoderParameters and you suppose to set some Scan parameters on it. Then you suppose to consume  onRead.Please refer the following C# code, i am not sure how you can do it in Delphi. I recommend to us .Net CF.

DecoderParameters.CODABAR = Barcode.DisabledEnabled.Enabled;
...
ScanParameters.BeepFrequency = 2670;
...
OnRead += new Barcode.Barcode.ScannerReadEventHandler(this.barcodeReader_OnRead);
...
EnableScanner = true;  // This will enable and Disable Barcode scanner

To communicate to your MySQL Database, have a Web service (in Dotnet either asmx or WCF) and add all your database stuffs there.

Hope this helps you

Regards

Deepu
