edit Solved it, still don't know what the problem was, but it is working now

As the title says I have a problem when trying to return a string.
My program just crashes when calling the get_class_name function

These are my functions:

+ Code Snippet

EXPORT DWORD get_class_name( LPSTR OldStr, int index )
{
	db.deleteString(OldStr);
	return db.String("test");
}

DWORD DBPro::String(LPSTR pstring )
{
	LPSTR rString=NULL;
	if(pstring)
	{
		int size=strlen(pstring);
		Core->CreateDeleteString ( (DWORD*)&rString, size+1 );
		strcpy(rString, pstring);
	}
	return (DWORD)rString;
}

void DBPro::deleteString(LPSTR targetString )
{
	if(targetString)
		Core->CreateDeleteString ( (DWORD*)&targetString, 0 );
}

Stringtable:

+ Code Snippet

"GET OBJECT CLASS[%SL%?get_class_name@@YAKPADH@Z"
