I wrote a program that should in no way open a new window, but still it does open windows and a hell lot of them... anyone knows why ? I believe the error is somewhere in a function I wrote to draw Circles. because if i comment the call to that procedure then it doesn't create all the windows anymore.
This is the code ofr the circle proc:
; proc draws a cirlce with center (x,y) and radius r
Circle proc hDc:HDC, x:UINT, y:UINT ,r:UINT , color:COLORREF
LOCAL d:UINT ;stores the x value computed by st(0)
mov eax,y
add eax,r ; counter
mov edx,y
sub edx,r
fild r ;st(0) = r
fmul st,st ;st(0) = r^2
fild r ;st(0)=r st(1) = r^2
fld half
fsubp st(1),st ;st(0)=r-0.5 st(1) = r^2
circley:
fld st ; st(0) = r-0.5 st(1) = r-0.5 st(2) = r^2
fmul st,st ; st(0) = (r-0.5)^2 st(1) = r-0.5 st(2) = r^2
fsubr st,st(2) ;st(0) = r^2 - (y+r-0.5)^2
fsqrt ;st(0) contains x value
fistp d ;st(0) = r-0.5 st(2) = r^2
fld1
fsub
mov ecx,x
sub ecx,d
mov edi,x
add edi,d
drawLine:
push ecx
push edx
push eax
push edi
invoke SetPixel,hDc,ecx,eax,color
pop edi
pop eax
pop edx
pop ecx
inc ecx
cmp ecx,edi
jnz drawLine
dec eax
cmp edx,eax
jnz circley
ffree st
ffree st(1)
Circle endp
can anyone tell me what's going on here ?
Thanks in advance

Whoops :redface: Nevermind I simply forgot to use the ret instruction :icon_redface:
