OLE Automation for Acrobat Reader

Hello guys

I have been reading some lines about OLE Automation for Acrobat READER and Full Acrobat.

So far I have seen most saying that Reader is not fully compliant with OLE. I really have zero experience with Adobe and before I buy a full acrobat license, I want to make sure of the following:

What I need to do is the next 4 simple calls:

1. Connect to Acrobat
2. Open a pdf file in invisible mode
3. Perform "Select All"
4. Copy Selection to clipboard

After that, I will importclipboard to my datawindow and I will be done for my programming task.

Have you had similar experiences about Acrobat OLE for PDF ?

some references are in help.adobe.com/livedocs/acrobat_sdk/10/Acrobat10_HTMLHelp

Thanks so much in advance for any hint.

Regards
