Hi Botagar

Firstly if your more familiar with C programing you may wan to try cscript rather than vbscript http://www.roborealm.com/help/CScript_Program.php

Then if the program is exactly what your using then try adding some spaces to your code instead of

if(RBdX=0)then

try

if RBdX=0 then

Take a look at w3schools they have a lot of good examples http://www.w3schools.com/vbscript/vbscript_conditionals.asp

Lastly microsoft did not give us any debugging tools for vbscript so I am afraid you have to go old school and use response.write onto the screen in order to get some understanding on what is going on.

VBscript IF statement issues

Tue, 30 Nov 1999 00:11:00 EST

Hi.
Background on me, i do a bit of C and C++ programming, and am trying to use the VB script plugin.
The 'IF' statement seems to playing havoc on me, because i can't seem to find the right syntax for a comparison.
I have this code:

RBdY = (RY-BY)
RBdX = (RX-BX)
if(RBdX=0)then
heading1 = 0
else
heading1 = (tan(RBdY/RBdX))*(180/3.14156932)
end if
SetVariable "Heading", heading1

RY, BY, RX, BX are all pixel co-ordinates i have determined before the VB script, and are read in via 'RX = GetVariable("RedX")' etc...
Im trying to detect if RBdX is equal to 0, so i can avoid a division by zero. however the if statement always fails and i'll get a division by 0 error when RBdX is 0.
I've tried '==', also tried '!=' or '<>' and reversed the logic, nothing works.

I can't seem to locate any debugging tools in the built in VBscript plugin, am i just being blind?
Also, is there no function for Pi?

I appreciate any help given on this problem.

Thanks.
