Basic, Vis' a Vis'

Factual Questions
1
      • Visual Basic 6.0: I want to draw lines in a picture box using the [line] method, but I want the lines to be in different colors. The help files give two ways:
    • using the RGB (n,n,n) method at the end of the [line] statement, or,
    • setting the pictureboxname.foreground value to one of the hex numbers in the default palette, before the [line] statement you wish it to affect.
  • My problem is, neither works. All I get is black lines; I can’t get any other color. I notice that if you try to use a hex number not in the existing (default) palette, when you try to move the cursor off that line the computer immediately returns an error. Am I doing this right? - MC

Not much of a VB guru, but here’s something you might try.

Make the lines a few points thicker. I had a similar problem once, and the color worked fine on everything except my spiderweb-thin lines…

Oh, and move the picture-box, temporarily. Make sure that the lines aren’t being drawn onto the form, then covered by the graphic.

Doubt it’ll help, but good luck anyway!

Depending on the color range you need, you could use QBColor(n) instead of the RGB function.

These options certainly worked for me

Picture1.Line (iXstart, iYStart)-(iXFinish, iYFinish), RGB(iColor * 64, 0, 0)

Picture1.Line (iXstart, iYStart)-(iXFinish, iYFinish), QBColor(iColor)
I wouldn’t worry about the lines being drawn in a different colour on another control - if you can see black lines on the picture control, they won’t be getting printed anywhere else.

Noddy question - you can actually see different colours with your current configuration?

      • I can only get one color of line to show per picturebox, and only if I use drawmode #13 and change the forecolor property in the properties window. IF I try to use any three runtime methods, all I get is black lines. If I switch the drawmode style, I get odd colors showing up, in some cases, depending on the drawmode but I need several different colors. The most I get playing with the drawmode is two.
