Re: Error calling a .net object
Still no dice. Im banging my head against the wall on this one. I know Ive
got the right path
I opened it up with cffile and dump it to the screen and
its there. I dont have an asp application using it, going to try that next.
If I can get it to work there, at least it will give me some indication of
where the issue might be.

Re: Error calling a .net object
Its not necessarily saying the method doesn't exist, it is saying it
doesn't exist with the arguments and/or argument TYPEs you are giving it.
Look at the types in the dump of the method you mentioned and try to
javacast() your values to match those types when passing them in.
example: opendesign(javacast('string',thisfile), javacast('int',0))
...assuming that it is actually expecting a simple string and int.
If that doesn't work, try posting the method dump or (if you have it) a
working.NET example of how it is used.

I have a problem I wanted to run by the list. Iâm recently back in the
coldfusion world after a several year hiatus. Iâm in the process of
trying to access the methods of a .net component, at this point as a
proof of concept. Once I can do something with it Iâll actually start
building the app.
I set up the object like this:
cfset dll = ExpandPath('./com/Interop.CADXLib.dll')
cfobject
class=CADXLib.CadX
type=.NET
name=cadx
assembly=#dll#â
Thatâs in my application.cfc, in the onRequestStart() method. Then in
my index.cfm I call:
cfdump var=#cadx#â
The object dumps just fine. I can see all the internal methods, including
the one I need to get things going, the OpenDesign() method, which (in
theory) opens a local file and reads the contents.
So next I set the actual filename I want to access:
cfset thisfile=1571269P01R01_ARTIOS.ARD
cfset thispath=getDirectoryfromPath(getCurrentTemplatePath())
cfset thisfile=thispath thisfile
This works, and outputting âthistfileâ gives me the correct path
location. So now I call the actual method:
cfset result=cadx.OpenDesign(thisfile,0)
Thatâs where I get stuck. I get this error:
Either there are no methods with the specified method name and argument
types or the OpenDesign method is overloaded with argument types that
ColdFusion cannot decipher reliably. ColdFusion found 0 methods that
match the provided arguments. If this is a Java object and you verified
that the method exists, use the javacast function to reduce ambiguity.
I javacast the arguments and get the same error. Method not found. But
based on the dump, the method is clearly there.
Has anyone encountered this or something similar?

Re: Error calling a .net object
I gave the benefit of the doubt but that is also my primary suspicion
(file object vs path).

So might look if the function is this:

Re: Error calling a .net object
Javacast the 0 as short and the path as a string and see how that goes.
example: opendesign(javacast('string',thisfile), javacast('short',0))

Re: Error calling a .net object
Anyone have any ideas if the introspection into .NET objects shows private
methods? May be the case that the method is private being shown in the
CFDump? I seem to remember this might be the case.
May be able to use this to decompile the dll and see what is what.

Re: Error calling a .net object
Iâll take a look at that. This âinherited an application with no
documentationâ is exactly my situation. This DLL is a black box. Thank you!
