Visual Graph Getting Started - Access Properties

Now we explain how to access element properties through a VB6 example.

1. Create a new project in VB6, right-click on Toolbox and select Components, and then check Visual Graph ActiveX Control and click <OK>.

2. Click vgctrl in Toolbox, and then draw an instance on Form1.

3. Double-click Form1 and write the following code in Form_Load event:

Dim d as Object
' Create a new graph file and enter Design mode.
vgctrl1.Design ""
' Add a circle element to this file.
set d = vgctrl1.vg.ActiveSheet.AddUnit( nothing, "circle" )
d.SetBounds 10, 10, 32, 32
d.BackColor = 0

4. Write the following code in vgctrl1_OnDblClick event:

Dim d as Object
Set d = vgctrl1.vg.ActiveSheet.Units( 0 )
d.Width = 96
d.Height = 64
d.SetPropertyValue "BackColor", 255
MsgBox d.GetPropertyValue( "BackColor" )

5. Run this project and double-click the circle to observe effect.
