problem mit setviewportorg und moveto

[Peace_VsC]

so hab das programm direkt aus nem totur übernommen
aber wie gesagt die funktionen "SetviewportOrg" und "MoveTo" funzen nicht

weiß zufällig wer warum
was hab ich falsch gemacht??

aja kompiler fehler:
93 D:\Peace\C\ctoturial\vswinmain\vswinmian.cpp SetViewportOrg' undeclared (first use this function) 106 D:\\Peace\\C\\ctoturial\\vswinmain\\vswinmian.cppMoveTo' undeclared (first use this function)

verwend DEV-C++ ide falls eine rolle spielt.

schon mal danke im voraus

[Peace_VsC]

ah sh** hab mich verlesen
dachte das SOLL hier rein

kann das wer verschieben??

tschuldigung

naja kann mir trotzdem wer helfen?

[gdi32]

stichwort: gegen gdi32.dll linken

[Pellaeon]

der kennt wohl einfach die funktionen nich
such mal lieber nach moveToEx(...) für die GDI-Linie und die andere Fkt. sagt mir garnix

[Peace_VsC]

ok movetoEx(..) lauft

bleibt noch das prob mit setviewportorg
