CDateTime uses a lot of Windows handles [message #33381] Thu, 26 April 2007 19:07 Go to next message

Hi,

I appreciate the CDateTime widget and decided to use in my RCP application.

But I noticed that a single CDateTime with the CDT.Dropdown style use
about 400 handles in my Windows XP Pro 32 bits.
So, if I add 10 CDateTime in an Editor they use about 4000 handles !

A Windows application is limited to 10 000 handles.
If I open more than 2 editors my app freeze.

I tried with the snippets and the same...

Did you ever notice that before ?

on those platforms?)

Hi,

What do you mean:
a) That the widget uses that much handles
b) The limitation of handles / process

You mean it is normal that a widget uses 400 Handles? Are you leaking or
allocating so many handles? I have never looked at the code but I'd
say using so many handles is always a problem.

I think I encountered similar issue. My rcp app seems to run correctly
on most of the machines. Unfortunately on some it doesn't - it throws
the "no more handles" SWTError.

I attached the log file with the stack trace - maybe it will be helpful.
For me it looks like the widget falls - in some conditions - into the
"endless" recursion witch finally ends with the error.

Hmm, I think you should using lightweight design, for examples:

http://www.spket.com/widget.html

These control only use 1-3 handler, just take a look at:

http://www.codeproject.com/

most complicated control are lightweight control, that's the same reason
all the web browser a lightweight control...
