ok, i'll add it to *my* project list... and hopefully you'll give me some guidance in those areas where my skull is too thick...

I added one more function, ActiveXObject, to CoHelper.ahk.
Although this function may not be as accurate as CreateObject(), I suppose it is the closest to VBScript's CreateObject() or JScript's ActiveXObject().

For example, in ZipFolder script, may replace

In another thread I am trying to intercept drag/drop operations. I am disabled by the fact that I have never done any COM programming before.

In order to do this, I need to (from MSDN's page on the topic):

• "initialize COM with OleInitialize, not CoInitialize." [CoHelper can do this: the OleInitialize() function]
  
  
• "expose an IDropTarget interface." [I do not know if this is possible in AHK]
  
  
• "register with the system by calling RegisterDragDrop." - and passing it a pointer to the object that exposes the IDropTarget interface. [Though CoHelper can call the function, I do not know what DLL it is in, nor whether I can create a pointer to an interface in AHK]
  
  
• Create the functions IDropTarget::DragEnter(), IDropTarget::DragOver(), IDropTarget::DragLeave() and IDropTarget::Drop() to be called by the system. [While I can create them as AHK functions, I suspect this is not good enough, and they need to be real functions with memory addresses and stuff.]
  
  
• Accept a pointer to a data object as a parameter to DragEnter() [Pointers in AHK? I don't know if possible.]
  
  
• Use that pointer to obtain the information from the IDataObject that is being dragged. [I am unsure of object manipulation is possible in AHK.]
  

So, I have questions :)

Is all the above possible in AHK?

Is there a lower level at which I could hook into drag/drop, so that I wouldn't need to place a window under the mouse in order to capture the IDataObject?

Am I using the wrong tool, needlessly hobbling myself using AHK? Should I instead download a C compiler and learn to program the Windows API in that?

Can you offer any other advice?

"relatively simple" he says! Way to scare me away from Windows programming! :P

But thank you - that is awesomely helpful, and I seems to be exactly what I needed.

Hi Sean + others,

very helpful script you wrote accessing COM.
I have some problems, maybe you can give me a hint
on how to solve my problem.

I am trying to communicate with the Citrix API through the ICA client.
I am new to this topic but I have to figure out how I can send
keystrokes and maybe also mouseclicks to a citrix application.

I tried to use PostMessage but this won't work on a Citrix window.

So now I am using cohelper.ahk to use the wfica.ocx.
I managed to login through citrix but now I get stuck on how to use
the keyboard.

Alright. Now some information.

I use

[Sean]

I don't use citrix, but I got the typelib of it. Try the following.
If still not working, tell me the ErrorLevel and A_LastError.
And, make sure there exists a registry key HKEY_CLASSES_ROOT\CLSID\{B5D6ED13-EDAA-4C2C-B2E2-26FD9BC1C710}.

[FlowPEE]

Sean,

thanks for your reply !

Unfortuanetely, that is not working.
ErrorLevel contains 0 and A_LastError contains 1008.

The reg key does NOT exist. Maybe there is the/a problem?
Why is the CLSID not registered and do I have a chance to
add it to the registry?

I tried your script with the new cohelper.ahk and the new AHK.

Do you need something else from me to support you?

Thanks for your help,

Florian

EDIT: btw, when I do e.g.

[FlowPEE]

Sean,

that didn't work either

So I guess I have to find a way to talk to Citrix support.
Thanks alot for your help though!

Amazing Sean! Not only have you provided support for COM early binding, but also late binding, and all in native AHK!

I've attempted to do a similar thing with another scripting language I use, but my high expectations turned it into a gross mess (I didn't want to require the API user to understand/deal with VARIANTs).

I owe you much for your posts because it helped me understand enough of the raw workings of COM to finally use it myself.

For the longest time I've wanted a super easy method to work with COM in my scripting languages. I assumed it was complicated, so I thought it would be nice if someone could at least make a small DLL to handle the dirty work. It has surprised me that no one ever has (or have they?).

Now that I know enough to do so, I'm putting together a DLL to do that very thing. It meets my needs well since I can use it in any language that loads DLLs. Plus, writing COM in C++ (or even C) is ridiculously easier than in a scripting language.

Since I have wanted this for so long, I'm curious if there's any other interest in a DLL like this.

Simple API usage example:
