Hi everybody!
I want to get selected text from an ole-integrated acrobat reader.
At present, to get the string, I select the text with the mouse, press
ctrl+c and press a button that reads the content clipboard.
To shorten the workflow, I post an "ctrl+c" keyevent to the display just
before I read the content of the clipboard.
The unsatisfying result of this operation: I get the old clipboard content.
The content is actual, only when I part the actions!
Can anybody help me with this problem?
I've written some code to illustrate this problem.
Just enter some text, press the "ctrlc" button (watch debug output) and at
the end "show clipboard".
Thank you,
Florian
