struct TestStruct {
    short Var1;
    float Var2;
    char Var3;

    struct TestStruct2 {
        char myType;
        CString myTitle;
        TestStruct2(char b1,CString b2):myType(b1), myTitle(b2){}
    };

    std::vector testStruct2;

    TestStruct(short a1,float a2,char a3): Var1(a1), Var2(a2), Var3(a3) {
        testStruct2.push_back(TestStruct2(0,"Test Title"));
        testStruct2.push_back(TestStruct2(4,"Test2 Title"));
    }       
};
std::vector testStruct;

//push smthng to vec later and call 
testStruct.push_back(TestStruct(10,55.5,100));
TRACE("myTest:%s\n",testStruct[0].testStruct2[1].myTitle);
