InsertBlock Method Inconsistent with Help

This method only seems to work (and works great) if the block is already defined in the drawing. However the help menu says:

"...

Name

String; input-only
The name of the AutoCAD drawing file or the name of the block to insert. If it is a file name, include any path information necessary for AutoCAD to find the file and the .dwg extension.

..."

If I specify the filename for a block that's not in the drawing I get the following error:

"...Automation Error. Key not found..."

However, I if use the VLisp function:

" ( vl-file-systime "MyFilename" ) "

then the expected file information is returned, meaning the file exists in the specified path.

" (2004 10 3 27 5 13 28 638) "

Yes, I am specifying the path, I am using forward slashes to delimit the filename fields, and yes I am appending the file name with ".dwg".

What am I doing wrong?

 

I figured it out.

When using ActiveX, the forward slash cannot be included in filename designations.

I substituted "\\" for "/" and it worked as expected.
