TAPIVISION Problem

Post by lionel.flore.. » Sat, 10 Jul 1999 04:00:00



Hello,

We're using a Genoa tool: TAPIVISION. It seems that this tool doesn't
work under WIN2000. Has anyone faced this problem? I've checked at
Genoa's Web but there is nothing special for Win2000. Does anyone know a
way to make this tool working or have another tool like it?

Thanks for your response.
Lionel.

TAPIVISION Problem

Post by Eduardo Suare » Sat, 10 Jul 1999 04:00:00


Lionel,

I have tapivision working on Win2000 (Beta2).  I just run setup and selected
the TAPI lines I wanted Tapivision to monitor and that's it.
When I run a tapi application that makes use of one of the lines I selected
during setup, tapivision pops up a monitor-log window...

I am not sure whether this helps. (?)

1. Problem with GDI & sin() (double & int problems)

sorry, i forgot the subject.. i am a lil bit tired and busy..

hello, i got a problem,
i want to draw the graph of mathematical functions like sin or cos or
parabel's (  f(x) = x^2 ).
i use a metafile object with class CPaintDC.

CPaintDC dc(GetDlgItem(IDC_SURFACE));

the point (0;0) is in the left up corner, thats ok....

i need it in the middle so i get the middle of the metafile object like
this:
int null_x, null_y;
CWnd *pSrf;
CRect SrfRect;
pSrf = GetDlgItem(IDC_SURFACE);
pSrf->GetClientRect (SrfRect);
null_x = SrfRect.right / 2;
null_y = SrfRect.bottom / 2;
// blah...

so,
now ill start to trying to draw the sin();

i tried it so:
int x,px,py;  // px and py are the points wich i use to draw..
px = null_x + x;
py = null_y - (sin(x * (pic / 180)));  // yeah, i know that i dont use
amplitude in this function, but i do in the real code!

so, now appears the problem,
sin() returns double value, thats ok, but
CDC::LineTo() requires int value!
so if i declare py as double, its not the solution!
when i give double value to CDC::LineTo() it would be converted to int.. so
its impossible to draw curve this way, becaue 0.5 as double will be 0 as
int!
so i tried to round the 0.5, but now i dont know why, i see not a sin curve,
i see a line...lol
i did my own function to round values:
its quiet easy and possible wrong.. but it works
int round(double x)
{
 double b;
 int c;
 c  = x;
 b = x - c;
 if ( b < 0.5 )
  return c;
 else
  return c + 1;

so, ill hope you can understand me and i hope that i dont forget something..
:-)
maybe one of you can help me, thank you !

(please dont tell me how bad my grammer and spelling is..thank you)
