Linking Autocad Area to VBA TextBox?

[bdickens]

Hi all,

I have a question I would like to ask about linking my vba programme to the "area" on autocad, I have written my program as a simple weight calculation program like this:
(Thanks to ab123456, msmith & johnwm on my last post)

Private Sub ComboBox1_Change()

End Sub

Private Sub UserForm_Initialize()
With ComboBox1
.AddItem "Steel"
.List(.ListCount - 1, 1) = "7.85"
.AddItem "Aluminum"
.List(.ListCount - 1, 1) = "2.60"
.AddItem "Bronze"
.List(.ListCount - 1, 1) = "8.46"
.AddItem "Cast-Iron"
.List(.ListCount - 1, 1) = "7.22"
.AddItem "Oil"
.List(.ListCount - 1, 1) = "0.85"
.AddItem "Water"
.List(.ListCount - 1, 1) = "1.00"
End With
End Sub

Private Sub CommandButton1_Click()

If TextBox3.Text = "" Then
TextBox4.Text = TextBox1.Text * TextBox2.Text
TextBox5.Text = TextBox4.Text / 1000000
TextBox6.Text = TextBox4.Text * ComboBox1.Value * 0.000001
Else
TextBox4.Text = TextBox1.Text * TextBox3.Text * 6.283185
TextBox5.Text = TextBox4.Text / 1000000
TextBox6.Text = TextBox4.Text * ComboBox1.Value * 0.000001
End If
End Sub

Private Sub CommandButton2_Click()
End
End Sub


Private Sub UserForm_Click()

End Sub

In TextBox2 is my cross sectional area of a polygon, region etc, what I would like it to do is that when I open my vba program I would like it to automatically input the "area" of the polygon, region into TextBox2.

Is this possible? and if so does anyone have any pointers?

Thanks everybody.

Hi bdickens,

Well, sort of... You'll want to look into XData and figure out a strategy for maintaining these, if these are typical type drawings or something you can create programmically, attaching XData isn't too painful, but if these are dynamic (meaning your areas will change frequently, or your users create) you may be better off forcing your users to select the areas you want to populate your box.
