Extracting attribute data

[j_r_auden]

I have a block in my drawing that has 2 attributes attached to it. Let's say length and size are the 2 attributes.
I need a little help writing this code as I am a C++ programmer.


For Each block In MyBlocksSet
If the size attribute = 1
size1count += this blocks length attribute
Else if the size attribute = 2
size2count += this blocks length attribute
............
............
Next

I am having trouble extracting the data though. How could I do something simple like extract a block's length attribute and display it. I know I am close but I can't seem to do something as simple as this.

Also, do you know of any good books on VBA in a CAD environment.
I can find many books on VB and VBA, but not many dealing with the AutoCAD aspects of VBA.

Thanks for the help !!!!!!!!

Unfortunately I don't have any specific advice but you could do worse that look here for a start.

check out my answer to your other post

it will be something like

For Each block In MyBlocksSet
Myattributes=block.getattributes
TheLength=MyAttributes(0).textstring
msgbox TheLength
Next  block

of course, if there is more than one attribute, then you need to check which attribute you actually have at any given time
