WinForms (.Net) VS VB6 Forms on Responsive -


i have client has visual basic 6 point of sale software system have pitched them work better in .net, refuse make change. argument vb6 app far more responsive , far can't disprove them. vb6 app lightning fast , on crt touch screen provides user experience.

i have not yet been able .net forms perform yet... there method improve responsiveness? perhaps wpf better alternative .net winforms?

vb6 made perform on ~1996 vintage hardware. took trick or three, notably uses window-less controls. there price, vb6 controls hard customize , look-and-feel pretty set in stone. can tell vb6 app hundred feet away.

winforms changed that, every control window, simple 1 label. several big advantages doing way, object model simple base object providing lot of functionality can customized little code. , wysiwyg designer support. big disadvantage, winforms programmers tend stuff window dozens if not hundreds of controls. easy do, designer makes simple. there price, dispatcher overhead significant , seen taking while these windows repaint themselves. visibly, giving perception of slow program. workaround is simple.

wpf went vb6 approach , uses window-less controls. improved directx-based rendering engine , strong support look-and-feel customization. , deep object model steep learning curve, primary reason winforms still used. windows-less controls available in winforms .net 2.0 additions toolstripitem classes , component vendors telerik.
