REMOVE @newmsg.String1 = @string("ha"); SUCESSED.

You have not provided a default constructor for your structure, thus the String1 and String2 members will hold random values, which the script engine will then try to free when you do assign the new string handle to the members.

greate WitchLord:

struct stMessage{
public:
stMessage()
{
String1 = new asCScriptString("ye");
String2 = new asCScriptString("ye");
}
int msg;
int Param1, Param2, Param3;
int Param4;
asCScriptString *String1, *String2 ;
};

error happenedd yet.

I think that i maybe to register the constructor ?

sucessed, thank you ,my lord.

Glad you worked it out.

Also, since the string members are handles, you don't actually have to allocate new strings in the constructor. You can just set the pointers to 0, and it will still work.
