simple exception handling

hello experts,

i'm very new on exception handling on a PDA, using embedded visual c++ 3.0, I would like to only catch CMemoryExceptions.
how can i do this?
i know it is with
     code where exception can get thrown
__except ... but here i'm stuck. How can i only catch CMemoreException?

Watch Question

  blah blah blah;
catch (CMemoryExcpeiton* exception)
  blah blah blah;

Should do the trick.  A catch block only catches exceptions of the type it specifies (or objects derived from that object).

Hope this helps.


in visual c++ this would work, but it doesn't in embedded visual c++.
embedded visual c++ doesn't suppport  this way of exception handling.

If you must use the try...except clause, you will need to write a filter routine to handle the event.  The try...except only catches terminating events, and under C++ the catch is much more flexible, but there could be reasons why you need the try...except block.

In that case, check out the example at the bottom of this page: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vclang/html/_langref_try_except_statement.asp

Hope this helps.

Oh and a list of teh exceptions you can filter on is here: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/debug/base/minidump_exception_str.asp

Sorry that the catch doesn't work in embedded C++.  Odd that.

thx for the fast replys,

i'll give it a try

and for the try and catch i found that windows CE doesn't support this, and if i try i get the warning
"warning C4531: C++ exception handling not available on Windows CE. Use Structured Exception Handling"

i'll get back to you guys, thx :)


and Lakshman you"re right, in some places u find that evc supports structured exception handling and some other places you find that it doesn't, and also if you try to compile u see a message they don't (^^)

i find it strange


evc 3.0 doesn't support, but evc 4.0 does :)
to bad i have to use 3.0
Upgrade to evc 4.0 :-)
