WM_TOUCH und GetTouchInputInfo

[Hofes]

Ich hoffe das ist das was du meintest.
Bekomme beim touchen dann genau das hier raus:


(0021DB2D){MultiTouch.exe} [0061EB2D] Unknown function at TMethodImplementationIntercept + $1583FD
(0021BD1F){MultiTouch.exe} [0061CD1F] Unknown function at TMethodImplementationIntercept + $1565EF
(0021DB38){MultiTouch.exe} [0061EB38] Unknown function at TMethodImplementationIntercept + $158408
//hier wird gettouchinputinfo() ausgeführt
