 Post subject: COM Invoke Problem
PostPosted: March 19th, 2010, 6:53 am 
---------------------------
COM Error Notification
---------------------------
Function Name: "InstantMessage"
ERROR: The COM Object may not be a valid Dispatch Object!
First ensure that COM Library has been initialized through COM_Init().
()

Will Continue?
---------------------------
Yes No
---------------------------

Using this code from somewhere on this forum:
Code:
#Include COM.ahk
stat = 4

COM_Init()
Msn := COM_CreateObject("Messenger.UIAutomation.1")
COM_Invoke(msn, "InstantMessage", "AFriendOfMine@hotmail.com")

COM_Release(pwb),  COM_Term()
Return


Can anyone shed light on this problem?

I guess you're on XP. This behavior is no longer present in Win7 with Windows Live Messenger. Anyway, read the thread:

You've got some of the right parts anyway:

Code:
#Include COM.ahk
stat = 4

COM_Init()
Msn := COM_CreateObject("Messenger.UIAutomation.1","",stat)
COM_Invoke(msn, "InstantMessage", "AFriendOfMine@hotmail.com")

COM_Release(msn),  COM_Term() ; make sure you're releasing the correct object pointer
Return

Nope. Same error again. :(
Btw, I'm using MICROSOFT OFFICE COMMUNICATOR 2005. So to assume that it makes no difference because its "the messenger" is valid, right?

Looks like Messenger is altered/disabled. Check the registry entry HKCR\Messenger.UIAutomation.

Code:
HKCR\Messenger.UIAutomation.
   CLSID
   CurVer
HKCR\Messenger.UIAutomation.1
   CLSID
Subkeys existing. No indicators (IMHO) that something is missing or disabled. Btw, Communicator itself is working fine.

You have to inspect the specified CLSID key too, HKCR\CLSID\{...}. BTW, it's the first time I heard about Communicator.

Yeah, I didn't know about Communicator until I started working for the company I work for now. I'm not sure if it's any help whatsoever, but in the code I'm seeing
Code:
COM_Invoke(msn...

This can't work if you're using Communicator?

No, I meant you had to inspect the key HKCR\CLSID\{B69003B3-C55E-4b48-836C-BC5946FC3B28}.

BTW, I'm suspecting Communicator disables/replaces Messenger or its derivatives, so creating Messenger.UIAutomation will be failed once Communicator is installed.

msn in this instance is just a variable containing the object reference, so that doesn't really affect anything. What may affect things is trying to retrieve a reference to an object that doesn't exist.

@ Murx

Run this and tell us what the message box produces:

Code:
#Include COM.ahk
stat = 4
obj=Messenger.UIAutomation

COM_Init()
MsgBox % msn := COM_CreateObject(obj,"",stat)
 . "`n"  msn1 := COM_CreateObject( obj ".1","",stat)
COM_Release(msn1),  COM_Release(msn),  COM_Term()
Return
