Title: How do I draw a Line?
Post by: Mvlawn on March 27, 2016, 01:24:55 PM

I would figure this should be super easy, however I can't locate a line tool. Can someone point me in the right direction?

Here are 4 different methods that can be used:

Option 1 : Install Visual Basic Power Packs

Option 2 : Use a drawing program like Paint, InkScape, Adobe Illustrator, etc to draw all of the line/shapes you want in a single image. Export the drawing to a PNG file. Add the image to a Panel or make it the Form background

Option 3 : Add a Label to the form. Set the Backgound color to the line color you want. Set the width or height to the line thickness

Option 4 : Use GDI+ drawing via code. For example, add this code to your form:
 
   Protected Overrides Sub OnPaint(e As PaintEventArgs)
        MyBase.OnPaint(e)

        e.Graphics.DrawLine(Pens.Red, 0, 0, 100, 100)
    End Sub




Option 1 is probably the easiest, but least portable to other machines that do not have the Power Packs installed.
Option 2 is my preference because of the flexibility I can get. In the Application Showcase, I recently posted some screenshots of a press HMI that uses this technique.
Option 3 only allows vertical and hortizontal lines.
Option 4  is typically used by professional code writers and requires a reasonable amount of knowledge of GDI+

You can also use custom controls from this topic:

Thanks for everyones help!!! I did try several of the methods, I was not able to get Godra's method to work due to an error that populated. I assume because I am running 3.99D. Any thoughts?

You got those errors since the file is intended for pre-v399d versions of AHMI.

Try renaming each of those AdvancedHMIDrivers.IComComponent to MfgControl.AdvancedHMI.Drivers.IComComponent.

I will try to post v399d file later.
