Hi Dave,
Default behaviour for the ICA client is that it shares the clipboard
contents between the TS session and the ICA client clipboard. SO if you dump
a whole lot of data into the clipboard (eg a screen capture), that data will
be background synchronised between the terminal server (metaframe) and the
ICA client. This takes time and in the case of Excel for example, will cause
a clipboard access timeout.
There is an application compatibility flag you can set to handle the timeout
a bit more elegantly. Easiest thing to do is to use the win2k version of
CMPTMAN to make an app flag entry for your application, just copy the excel
settings.
Otherwise, run up regedt32 (not regedit) and navigate to
HKLM\Software\Microsoft\Windows NT\CurrentVersion\Terminal
Server\Compatibility\Applications. Create a key with the same name as your
application executable (less the extension, eh MYAPP.exe, create MYAPP key).
Now save the EXCEL key, and restore it to your "application" key (eg as in
example MYAPP). That may fix your issues.
The other course of action you have is to disable the shared clipboard
(mfcfg > ica-tcp > client settings > disable client clipboard mapping.
The only scenario where I enable the shared clipboard is when users are
running published apps where they need to be able to cut and paste between
them and local apps. Otherwise it can cause significant performance hits and
timeout issues on WAN connections.

Rick

Subject: [THIN] MF XP and losing the clipboard content
Citrix XPe FR2
W2K
Got an issue where users have a small inhouse application that copies a
screen of text data to the clipboard using the following VB function -
Clipboard.Clear (to clear the clipboard) and then Clipboard.SetText
ctlTXText.Text - to write the text to the clipboard.
Now the issue is that "randonmly" the users clipboard gets cleared before
they get chance to paste this. I'm guessing that Citrix is having some kind
of contention and wins over the user. As this NEVER fails on a local
instance of the program.
Is there a hotfix / reg entry to protect the users clipboard contents ?...
If not.. could someone explain the circumstances in which the users
clipboard gets emptied - or do I need to write with another func ?.
Thanks
