win32/ question on passing and returning strings

stephanstephan Member Stephan StapelOrganization: Stephan StapelProject: BristolNG
Dear list members,

I have some problems on either returning and passing strings from/ to remote functions.
I attached a VS7 project to this posting consisting of client and server for this Ice interface:
interface FirstClass
{
	string getValue();
	int getValueVariant(out string s);
	
	void setValue(string s);
};

Unfortunately, a call to getValue() and setValue() does not work in the case that the strings I return from/ pass to those functions has 16 characters or more (16 seems to be the initial length of a std::string, at least under win32).
The variant I made, getValueVariant() works for some reasons so I can avoid the getValue() problems.
For the last case, setValue(), I can't imagine a work-around.

Or am I doing something wrong? Help appreciated :)

regs,

Stephan

    Hi Stephan,

    You didn't describe your error, but I built your example and received an assertion failure in the client indicating a memory management error. Everything works fine when I change your projects to link with the debug versions of the Ice libraries, so I assume the assertion occurs when memory allocated by one heap is being freed by another.

    Take care,

    Yes, that was exactly the error you also found. Thanks for pointing to this dummy issue, when using Ice's debug libs, everything works fine *dooh*.

    Kind regards!
