Hi people!
I developed a system using M$ VB 6.0. :(
The client now wants an "open" system.
Which tool/language to use on Linux.
Have been a redhat user (not as a developer)
since rev 4.0. currently running rh7.1.
The program has an Oracle interface and
uses "twain" compliant devices.
(similiar to M$ "vidcap" program).
Really only need a data capture screen and a
video feed to capture frames from.
Any help/information is welcome.
Thought of using Python - but is that a solution?
As a straight "C" programmer - somehow not
migrated to C++ yet.
Regards.

VB and open system? haahhaha (excuse me) .... so basically your customer wants a complete re-write then? I suggest you look into Qt (http://www.trolltech.com) library. A multiplatform application devlopment toolkit with database support and a very user friendly and intuitive API. There is a GPL-style version available and various commercial licenses. I've been using it at work for the last 6 months and I must say that I'm quite pleased with it. Trolltech also offers *excellent* support, they have thusfar allways answered all of my questions within a day (and sometimes within a matter of hours).
As for the capturing of a video stream, this is quite easy under linux (did it myself a while back , grab the stream of a webcam and use it as an OpenGL texture) with the video4linux interface.
I'm not a windows programmer so I don't know your options for windows concerning video streams (prolly somewhere in MFC orso, or in directx, but I wouldn't know (http://smile.gif) )
The videostream code would be heavilly #ifdef'ed tho, which is practically unavoidable when programming for multiple platforms.
Another option is to persuade your customer to wait a year orso till the new GNOME .NET project is matured, which will offer an API similar to MS's .NET, though this is very much in early development stages (look around a bit on http://www.slashdot.org, (http://www.slashdot.org,) there was an article on it a short while back).
hope this helped.

Like BadKarma said, check out Qt. Qt rocks for graphics and desktop applications. PHP, Python, C all have ties to the qt libraries. Best of all Qt is available for windows. so cross platfrom implementation is always a possibility. Check out www.trolltech.com (http://www.trolltech.com) for more info.
