But do many of them think about implementing completely new Software (that could be done in fpc/Lazarus, while obviously the current is done otherwise) on such legacy machines (or development crews) ? I've talked with Casio employees last week and they told me that Windows CE will stay for the forseeable future just because of this.

Last week I had the chance to speak to Casio workers on a mobile conference in Munich. Casio is also producing rugged industrial devices and they are now only beginning to provide Android based phones. They told me that they'll be doing a two track approach for the foreseeable time. Other companies like Motorola Solutions (aka Symbol) don't seem to want to switch to Android at all. And also it's not always possible to dictate your customers what devices they should choose.

While I was intrigued when the .NET virtual machine (in fact the correct therm here is CIL rather then .NET) came up I feel that CIL now has been nearly killed by Java, even though nowadays there is decent Linux and Mac support for CIL and I still think that technically CIL is more advantageous. -Michael -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

The rental firm people try lots of combinations of configurations in the Cipher CP30. And the problem persists. Wild guess: maybe the Intermec scanner is using a Windows message that is not handled by the LCL. What you could do to check this is to use your own Window Proc and write out all messages directed to the edit control. An example is written here: http://wiki.freepascal.org/Win32/64_Interface#Example It works for WinCE also, because I'm using this to handle some custom messages as well (I don't remember which though, but they are not related to LCL controls). If my assumption us correct then you you'll need to use this Window Proc to set the edut's text manually. If my assumption is incorrect, then I'm afraid that I can't help you :( Regards, Sven -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
