DLL

There is a DLL call example in AutoCAD program folder,

"C:\Program Files\ADT2\Sample\ActiveX\ExternalCall\",

that called from VBA project.

I would like to see how it works within VLA project. I've tried and
unsuccessful.

Here is my try.



Command: (setq MC (vlax-create-object "ExternalFunction.MyClass"))
Initializing VBA System...#<VLA-OBJECT _MyClass 00172668>



Command: (vlax-dump-object MC t)
; _MyClass: nil
; No properties
; Methods supported:
; CubeVolume (3)
T



(vlax-invoke-method MC "CubeVolume" 5.0 5.0 5.0)
0.0





I've tred to import methods and properties as:

(vlax-import-type-library :tlb-filename "C:/Program
Files/ADT2/Sample/ActiveX/ExternalCall/externalfunction.dll"
:methods-prefix "XXX::"
roperties-prefix "XXX-"
:constants-prefix "XXX_"
)
T

But, even though this function returns T there will be no XXX... symbol
defined in AutoLisp

(acad_strlsort (atoms-family 1)) symbol list



Can somebody show a simple example of how to call this dll from VLA project?

The "externalfunction.dll" file and accompanied source files can be found
in:

"<AutoCAD installed Folder>\Sample\ActiveX\ExternalCall\" folder



Thanks,

 

Try this:

(vlax-invoke-method MC 'CubeVolume 5.0 5.0 5.0)

or this

(vlax-invoke MC 'CubeVolume 5.0 5.0 5.0)

 

(vlax-invoke MC 'CubeVolume 5.0 5.0 5.0)
Works,
thanks
