haha, thanks man. you're a pretty smart guy for someone that's doing the hsc , with all this knowledge of vb and all. i wonder how you find the time to study and help others on bored of studies?
my program has a couple of glitches and problems.
when a different data type is entered into a textbox, an error occurs, is there a way to make a messagebox appear to say that a proper data type is to be inputted?
the scrollbars that i make don't work like want it to. it doesn't increment...
hey thanks everbody for your support.
ok, here's the thing. i've got these labels, and the text in it (numbers in the 1000's) changes frequently in my program, but i cant get the thousands separator to work despite the fact that i even changed the data format and ticked the box for the...
to give you an idea of what my graph would look like:
only the positive side of both axis would be graphed [ie. (loan amount) x>=0 &
(the duration in months)y>=0]
the graph i think should turn out to be a line, but it should have the duration of the loan on the x axis and the total...
urrghh.. i tried my best. ive attached my project. see if you can try and fix it up for me. you're a lifesaver! oh..and btw in my project i put up textboxes for inputting the loan, month and rate amount. do you think i could get the get the graph to change everytime i click calculate...
sasquatch and others:
i tried to put in the code, the axis came up fine,i also tried various functions but i didnt see any function graphs come up.
maybe i did something wrong...

does anyone know who found the mass of an electron?
jj thompson found the charge to mass ratio...
then millikan found the charge...
but how did he find the charge without first knowing the mass? he may have known the equation m=vd but how did he know the volume of the oil drop and the density...
you may want to write this down on paper...lol
how do you prove that " the derivative of inverse sine (x/a) is = to
1/√a^2 - x^2
and -prove that the inverse of tan x =
the derivative of inverse tan x, times x - (x / 1+x^2)
this question may be related to simpson's rule because...
thanks... and also, is there a way to include a line graph and make it change as you input different variables into the textboxes?... like um..the amount you owe on the y-axis and the months on the x-axis so it kinda looks like an exponential?
(the oildrop in the magnetic field experiment)
why does the results in milikan's experiment vary, why isn't the charge of an electron exactly -1.602 x 10^-19? and what was the thing that millikan needed to realise in his experiment in order to realise the correct results?.... thanks {*(00)*}!
in regards to textboxes in vb(visual basics) how can you make it so that you can write large numbers e.g. (250,000) in them and make them work in formulas without getting an overflow error?
btw. im making a program that calculates loan repayment. ......mike
yo!, thanks M.D.!
...but i'm still a little confused with Q19 2002,
the answer is...
(c) Change the inner loop counter to count by columns and the outer loop counter to
count by rows.
what's with the inner and outer loop counters? how would it make a differnece?
can someone please help me clarify the reasons why the answers for these questions are so?(these are multiple choice)
i also added links to the papers
i was baffled with this question...
Q11 2001...
