Another bug, I think

Here is the code:
nRet = (asERetCodes) pScriptEngine->RegisterObjectType("_String", sizeof(_String), asOBJ_VALUE | asOBJ_POD | asOBJ_APP_CLASS_CONSTRUCTOR | asOBJ_APP_CLASS_DESTRUCTOR | asOBJ_APP_CLASS_ASSIGNMENT);

Exp:
we have a our own _String class. It is very similar to std:string. U can use it to test.
We did not use handle, instead we used Value + class + constructor and deconstructor.
Everything going to be fine unless the Add operator.
I test on == != +=. they are working properly.
but with + operator on any combination: _String + string, _String + _String, string + _String is not working.
I set the break point on the function, I found one of input is corrupted.
For example:
_String("ab") + "a". In the code: "a" + "fjdsklajfkldsaklfjdklsaj"(corrupted data);
I set the break point in the constructor and deconstructor. It did not come to deconstructor before add operation.
By the way, the script does not support: _String a; a+= "a" + "b" ; _String b = "c"; a += b + "c";
but it does support: string a; a+= "a" + "b"; string b = "c"; a += b + "c";
Can u help me on this? otherwise, I need to Create the reference counter and do the same registeration as string class.
Cheers.

Just reposting your source code to get better formatting for easier review.
I don't see any obvious errors in your code. It may indeed be a bug in AngelScript. I'll have to investigate it.
You may however want to remove the asOBJ_POD from the type registration. Since your _String class obviously requires a constructor to be initialized, it is not a good idea to use this flag, since it tells AngelScript that the object memory doesn't require any special initialization. This shouldn't be the cause of the bug however, since you're apparently registering all the necessary behaviours.
Also, for some reason you've not registered all the behaviours to take const references as parameters. This wouldn't be an error from your side, however, it is possible that it is what triggers the bug. Try changing constructors and add behaviour to take the input parameter as const reference, and let me know if that helped in any way.

Andreas

Sorry for that.
I just came to this forum, never know source tag before.
But I will do this better next time.
Is information enough? should I provide some more?
Thanks

I edited my previous post. Please re-read it for a possible work around.
This information should be enough to get me started on the investigating the potential bug. If I'm not able to reproduce it I'll post another message here to ask for more information.

I used to put const, because it not working, so I tried to remove const and see wat happened.
Anyway, not working. :)

I found the problem. You need to change the flags used to register the type to:
Actually, the real problem is that the asOBJ_APP_CLASS flag was missing (asOBJ_APP_CLASS_CDA is a combination of asOBJ_APP_CLASS, asOBJ_APP_CLASS_CONSTRUCTOR, asOBJ_APP_CLASS_DESTRUCTOR, and asOBJ_APP_CLASS_ASSIGNMENT).
I'll have to add an extra validation for this in AngelScript so that it can return a proper error code should this happen again.

So cool. I think I use documentation online.
I think it's out of date, is it? or I open the wrong link?

nRet = (asERetCodes) pScriptEngine->RegisterStringFactory("_String", asFUNCTION(_StringFactory), asCALL_CDECL); assert( nRet >= 0 );I try this, but the input to second parameter of _StringFactory is corrupted.
I register this after I registering string class. Is this the problem? Or I need to register the object as a ref?
Can I make a object to be
asOBJ_REF | asOBJ_APP_CLASS_CDA Cheers.

You can only have one string factory. So if you've already registered the string factory for std::string and you register again for _String, it will overwrite the previous string factory.
The string type doesn't have to be a reference type in order to work with string factory. Take a look at /sdk/tests/test_feature/source/stdstring.cpp for an example on how to register the std::string as a value type.
If you're using a similar implementation it could be because AngelScript thinks the _String type is returned in one way while C++ actually returns it in another way. If AngelScript thinks the type is returned in memory, but in reality it is returned in the registry by the application, then you'll get these corrupted parameters. Can you show me the class declaration for the _String type? I need to know the members in order to verify if you've used the correct flags while registering the type.
The online manual is a bit outdated, but not that much. I haven't been able to connect to the website via FTP to update it. But I'll get to that in time. The latest manual is always available in the SDK.

......
I do not understand. It did not work yesterday, but it's working now.
It may because I did not clean up yesterday? No idea.
Thanks for the hint.
by the way, I tried to compile and run the test cases. None of them working (MSVC6 - 8).
It always have linking error.
I use VC 6++ and VC 2008.
Do u have any idea? Sorry for so many questions. I just swap from Java programming into C++.
