• CRT, do we still need to redistribute it ?

  - by leeeroy

  Do we still need to bother with vcredist.exe when distributing windows native applications ? Does any of these come bundled with Win-7 ? If not, are there any technical reasons these are not shipped to people via e.g. windows update - insteadof letting us burden the customers with yet-another-thing-that.must-work ? (Ok, that might sound argumentative, but I'm really wondering the reason these libraries are not default installed/updated on windows machines)

• Are there any programmable barcode scanners that can call a webservice?

  - by Mark Redman

  I am looking at integrating a C# application with a barcode scanner. The last time I did this was with Delphi 1 (win 3.11) using a scanner that plugged in-line into the keyboard cable. Looking around it appears most scanners are USB based these days and assume they emulate keyboard entry. Anybody know of more sophisticated/programmable scanner that can call a webservice or even just do a basic POST/GET this would eliminate the C# application and the computer to support it?

Win API SetTextCharacterExtra solves the problem for Tcanvas, but I tried hard to implement this behavior as a property for my own TEdit Component (a year ago) and despite of my various desperate attempts to do this, I failed. Thanx in advance.
