Crashes it at or before the Close() command? The extra closing parenthesis '}' before the Close() command would produce a compiler error. If this is remaining from other code not shown here, the error may be sourced there.

Solution 1

As correctly noted by Jochen, you should get a compiler error similar to:

VB

Error   'LoadArchive' : undeclared identifier

(because LoadArchive is out of scope outside the try block).
If you don't, then there is another LoadArchive in your previous code and..., do you see the problem?

Solution 2

Oh actually by mistake i put closing parenthesis before "LoadArchive.Close()". Its not there. And my code gives runtime error while executing "LoadArchive.Close()" statement. Later i found it is throwing exception. So i put another try catch block for this statement. Now code is working fine. But i could not able to find exactly which exception it is throwing.
Thanks for comments.

You should not pass such information as solution. You should edit your question and append this information prefixed with an update indicator (e.g. [UPDATE]).

You did not need another try catch block. You can use the existing one. With CFileException, you can add the values of the m_cause and lOsError members to your error message and show it always (not only upon ERROR_FILE_NOT_FOUND). When an exception is thrown and running the debug version of your program from the debugger, have also a look at the debug output to get some information about the exception.
