Good afternoon all!

I'm still not comfortable enough with NET to work up solutions, so I've been muddling about with VBA.

Converted some code and merged some modules work get the attached workbook going...

Works great, but struggles with embedded raster images.  Pretty sure the CAD department is embedding using Raster Design, but I should verify.

The problematic file contains 0510 in the name...hence the debugging code.

I've managed to use some wonky error trapping to resume and pull the attributes from two of the three drawings which contain embedded raster images, but the last drawing is giving me fits, so I'd like to do it "right"

(Probably need to use c#...)

Code below and the actual workbook is attached. 

Using vanilla 2017 on my box.

Code - vb.net: [Select]
  1. ' Determine if the chosen block is present in the drawing
  2. For Each oBlock In oDBX.Blocks
  3.    If UCase(oBlock.Name) = UCase(gsBlockName) Then
  4.        BlkExist = True
  5.        If sPath Like "*0510*" Then
  6.            ' Debug.Print oBlock.Name
  7.            Stop
  8.        End If
  9.        Exit For
  10.    End If
  11. Next oBlock
  12.  
  13. ' Open each layout
  14. ' Look for the title sheet block
  15. ' If the block if found extract the attributes
  16. If BlkExist Then
  17.    BlkFound = False
  18.    Set oLayouts = oDBX.Layouts
  19.    For Each oLayout In oLayouts
  20.        sngBlkCount = 0 ' reset the counter for each layout
  21.        ' If oLayout.Name = "0510" Then Stop
  22.        If oLayout.Name <> "Model" Then ' Paper Space
  23.            ' To Do : Add status bar update
  24.            ' Place the folder, file and layout name
  25.            ' into the Excel worksheet
  26.            ws.Cells(glRowCounter, 1) = fName
  27.            ws.Cells(glRowCounter, 2) = Right(sPath, Len(sPath) - InStrRev(sPath, "\"))
  28.            With ws.Cells(glRowCounter, 3)
  29.                .NumberFormat = "@"
  30.                .Value = oLayout.Name
  31.            End With
  32.            Set oBlock = oLayout.Block
  33.            For Each oEnt In oBlock
  34. '                If oLayout.Name = "0510" And (TypeOf oEnt Is AcadBlockReference) Then
