Barcode App on Symbol (now Motorolla) WinCE based handhelds

[Vincent Snijders]

I did put it on sourceforge and sent the link to Arnold, assuming that he would update the wiki. I did that yesterday myself and added this link: http://sourceforge.net/project/showfiles.php?group_id=92177&package_id=323770

Hello.
I have a Motorola/Symbol MC9090G that has an RFID scanner. I'd like to know how to scan RFID tags using Lazarus Pascal. I'm  already scanning barcode labels (using SCNAPI32.DLL). How do I select the scanner between barcode and RFID? Is there other unit available for doing that?
Thanks.

I have a Motorola/Symbol MC9090G that has an RFID scanner. I'd like to know how to scan RFID tags using Lazarus Pascal.

It's been 15 years since I used those ex-Symbol hand held devices, but I will try to be of some help anyway. There are two ways you can use scanning device on them. First is to use a Symbol scanner data wedge application to redirect scanner input into any edit field that is in focus. That is the most simple way and that looks to your application like user has typed him self the barcode or RFID number, so programming is easy. Second is to use Symbol provided DLLs directly, and that is what you see that SymScan does - a component wrapped around 'symscanapi.pp' which contains bindings to 'SCNAPI32.DLL'. For RFID scanning there is no such component. You have to make it. As the SymScan author had to download C/C++ SDK and convert 'SCNAPI32.DLL' bindings to Pascal, you will have to download SDK and convert 'RFIDAPI32.DLL' C bindings to Pascal. If I remember well in the time of Symbol it used to be called Symbol SDK, in time of Google/Motorola it was called Motorola EMDK, and now in Zebra time they call it EMDK for C.

Here are some links to give you some startup info:

I'm already  using the synscan unit with Lazarus Pascal. It works great! Bur my Motorola Scanner is an MC9090G, with the RFID scanner installed. I'd like to know if anyone here has the Lazarus unit that supports RFID reading. Thanks in advance. Ricardo Ramos - Brazil - e-mail: rico@ricardoramos.com.br
