getting value of COM Object method argument (byref)
I asked this question in other thread, but didn't get a solution.

I tried with few COM objects , including, simple VBA class method
to get return value of a method argument(simple string), means:

myCOMObject.myMethod(returnValue)
the returnValue equals "" always.

when I use a return value with Property(function)
it works correctly, means

returnValue := myCOMObject.myProperty()
I get returnValue , correctly equal's "myValue"

is there a special syntax in AHK_L to get correctly the value of
method argument ? or there are some limitations about ?

any help will be appreciated.

Split from http://www.autohotkey.com/forum/viewtopic.php?t=77068 because this may not be a bug.

can you post some example code for me to try?

the code link you gave is from local hotkey function, if I understand.
I pointed on COM object instance and getting
a return Value from it's method.

the most simple example I made with VB(6) I made, something like:
in VB in DLL: myDLL.DLL

and in AHK_L:


I get, the returnValue always equal "". should be "myValue"

I made the above VB sample code, because I didn't succeed to get the return value from some external COM objects.

I also didn't manage that yet (see here).

One thing I thought of but haven't yet tested is using some attributes (MarshalAs etc.) in the C# code. Maybe that helps you.

But if you also get this with other COM objects, this may be a bug.

Does this help: Com Events - Using ByRef Parms

Also, you never provided a link to the documentation for this Com Object (API Reference), or a working VBScript or JScript example that we can all try.

jethrow,

VB6 method
I gave above a simple VB method, initiated by class
do you need more info about ?

with JScript
I wrote you, that I didn't succeed to get byRef value from COM object.
with VBscript I got error mismatch, that only Variant values can be passed

so it means, that with AHK_L I cannot pass byref from COM object ?

perhaps the dll needs to be registered?

rani, can you post your dll? then we don't have to try to compile it. Use autohotkey.net to host it.

is is after registry of course.
I can send you the whole VB project (saved as activex dll) (very small) with it's dll and the .ahk that runs it
how I send you , by mail ? to what address
what is autohotkey.net host ?

I think better to send the .dll then just the source.
I can also send screenshot's

I also got it after first compile, but after I made that VB project has same name as the .dll (I think this was the reason)
I got correct ComObjCreate

hi engunneer,
have you some advance ?

or you wait for me ?
if yes, can you give any mail address ?
if not:
how is the procedure to send the .dll+.ahk to qutohotkey.net ?

create account on Autohotkey.net
upload files
post links to files here
profit?
