Using Line (I cant work out where i have gone wrong)

[rudvs2]

Hi chaps me again !!!

im trying to draw a line around the edge of a picture box

my code seems fine it doesnt gereate any errors but i dont get a line either can someone check my math is right ??

ps i have tried setting the scalemodes to pixel as well as twipsperpixel

this example is in twips where 6 twips = pixel

Private Sub Form_Load()
frm1.ScaleMode = 1
pic1.ScaleMode = 1
drawbox
End Sub
 
Public Sub drawbox()
Dim LTop As Integer
Dim LBottom As Integer
Dim Lleft As Integer
Dim LRight As Integer
 
pic1.Cls
 
LTop = pic1.Top + 6
LBottom = pic1.Top + pic1.Height - 6
Lleft = pic1.Left + 6
LRight = pic1.Left + pic1.Width - 6
 
pic1.DrawWidth = 6
 
pic1.Line (Lleft, LBottom)-(LRight, LBottom), RGB(127, 157, 185)
pic1.Line (LRight, LBottom)-(LRight, LTop), RGB(127, 157, 185)
 
End Sub

any Ideas people??

[rudvs2]

Never mind i found out where i went wrong lol

I forgot to ake the picture box Autoredraw property to True

DOH

Eh, you should use

0 for left and top

and

scalewidth instead of left + width

and

scaleheight instead of top + height

Doesn't a line have to be given 4 points?

I don't think you've passed 4 points to it...

[peet]

??

pic1.Line (0, 0)-(pic1.ScaleWidth - 15, pic1.ScaleHeight - 15), , B

seems u do alot for little... ?

Who is this to?

OK #1 you pass 2 points ( a line is defined by 2 points in case you haven't taken algebra 1 yet )

And both rudvs2's code and mine passes 2 points.

i think he was referring to a rectangle having 4 lines. Rud's code only had 2 (bottom and right). But anyway, Peeeeeeet is the scandi god and is right that a B (for box) line method is much easier (or even a shape control).
rud's whut yuh dun mut, yuh furgut huh tuh pruhgrumm??

OK FINE

You wanna go me? Bring it

To put a line on the screen
you need four values

X1, Y1, X1, Y2

I've done Algebra

I'm on a scholarship to my school

I've got full marks on 6 out of the last 7 maths tests...

And I'm probably going to do Year 11 maths next year (although i'll be in year 10)

Anything else you want to know?

I'm not a dumb ass you tool

[beachbum]

Settle down there tiger!!!

1...2...3...4....5........

[da_silvy]

Well he keeps on having cracks at me.

i'm really starting to get quite pi$$ed off too

[mlewis]

Jeez da_silvy...calm down and quit taking everything so personally.

Although you have the right to your opinion, and you are allowed to say that you dislike me, please do not do so in your signature.


You are perfectly correct that a line needs X1, Y1, X2, Y2; I agree.

However: (X1, Y1) is one point, and (X2, Y2) is the second.

Therefore you need 4 values, but 2 points.


None of this is intended to flame you, "have cracks" at you, or anything of the kind. These forums are here so people can share the knowledge and experience they have with others. Its OK to be wrong; I've been wrong many more times than most people I know, probably including you. If you don't make mistakes, you can't learn from them, right?

Don't take this so hard, and please don't be so antagonistic, or treat me like I am trying to cut you down. This is not my intent.

This is the second time I've had to do this; let's not have it happen a third time OK?

:: offers to shake hands, shutup, and never bug you again (well, maybe I'll bug you again in a looooong time ) ::

[da_silvy]

OK then

Thats alright

I meant to say values before.

Truce now

[mlewis]

Truce...*whew*
