To VB Guru or experts....
Here what I was going to do is working on a project based on my finals. what I intend to do is to get getting needle to drawn on picture box... and at the point it will change based on values at run time. But at this point I am unable to understand how it work or what these calculations defins so I am kinda hoping anyone with knowledge or experience in trig calcuation would be able to explain it to me clearly... that might help me out to do a few adjustment on calcuations. so here is the codes:
My understanding...Code:if PSI < 60 then
PSIANGLE = 0-((60-PSI)*0.75)
Else
PSIANGLE = ((PSI-80)*0.75)
End if
It states if the Value 'PSI' Is less than 60Code:if PSI < 60 then
what I dont understand is....
orCode:PSIANGLE = 0-((60-PSI)*0.75)
PSIANGLE = ((PSI-80)*0.75)
0.75 is a twip... actually what is twip, what does it have something to do with it? Also the calculation on
(0-))PSI - 60 ) *0.75( and ((PSI - 60 )* 0.75 seem to vague to me
Thats a code for needle to display into pictrue box
I understand this is making a lines 'needle' to center... but if I was going to try to do few adjustment, I would need to understand how to do thisCode:PICPSI.Line Step(0-(500 * Cos (PSIANGLE)), (-0-(500 *Sin(PSIANGLE)))-Step(0-(250 *Cos (PSIANGLE)),(0-(250*Sin(PSIANGLE)))
FApparently, it sound complicated.. If anyone couldnt get toe xplain this would you happen to know which website that provide information or clear expaination on these code definations? Let me know
Thanks ina dvance
