GDL
Hallöle,

must the Scrollbereich one Scroll bar not of less to plus weg.
See example:
CompileMarkSeparation
declare ende%,scrollbalken&
cls
scrollbalken&=create("hscroll",%hwnd,"",10,20,300,25)
SetScrollRange scrollbalken&,-200,200
SetScrollPos scrollbalken&,-10
sleep 300
SetScrollPos scrollbalken&,150
sleep 300
SetScrollPos scrollbalken&,-200
sleep 300
SetScrollPos scrollbalken&,0
'setscrollpos geht im negativen Bereich
'durch Drücken auf den kleinen nach Linkspfeil kann man auch den negativen Bereich anfahren
'mit dem Regler den negativen Bereich anfahren geht nicht. Regler springt immer zum positiven Anschlag

whilenot ende%

wend

there was objectively another bow drin, the though always drin was:
The suitable Message gives The Scrollposition as Word (0 ... 65535) back. If the Value is greater than 32767 is, must therefore 65536 abgezogen go, around the right position (-32767 ... +32767) To detect. this step fehlte bislang.

After nunmehr almost 20 years becomes too this bow gefixt!

'SetScrollPos scrollbalken&,-10
'sleep 300
SetScrollPos scrollbalken&,150

SetScrollPos scrollbalken&,-200
sleep 300
SetScrollPos scrollbalken&,0
'setscrollpos geht im negativen Bereich

whilenot ende%

CompileMarkSeparation
 $H commctrl.ph
DEF GETSYSCOLOR(1) !"USER32","GetSysColor"
declare slider1&,slider2&
Set("TrueColor", 1)
cls GETSYSCOLOR(15)
Set("decimals", 0)
slider1&=Control("MSCTLS_TRACKBAR32", "Trackbar01", $54010004, 10, 100, 400, 40, %hwnd, 2011, %hInstance, $00010004)'Horizontale Trackbar
slider2&=Control("MSCTLS_TRACKBAR32", "Trackbar02", $54000017, 50, 200, 40, 100, %hwnd, 2012, %hInstance, $00010004)
SendMessage(slider1&,~TBM_SETRANGE,1,MakeLong(-100,100))'die 1 erzwingt das Neuzeichnen des Sliders
SendMessage(slider2&,~TBM_SETRANGE,1,MakeLong(-200,400))
SendMessage(slider1&,~TBM_SETTIC,1,0)

whilenot %scankey=27

    waitinput
    locate 1,1
    print "Trackbar 1:";SendMessage(slider1&,$0400,0,0);"  "
