[ad_1] I have no idea why, but changing the access specifier here: protected: D3DDraw m_cDraw; DXInput m_cInput; To public solved the problem, it’s a hack but I’m okay with that đŸ˜€ Thanks anyway for attempting to help [ad_2] solved C++ object reference corruption [closed]
[ad_1] N is uninitialised meaning N could have any integer value. That unknown value is copied to M, and then scanf() called to assign a value to N. The program needs to verify that system calls (like scanf()) has done what was expected with user input. Below is a “better” version that tries to protect … Read more
[ad_1] What does the arguments (char * &str1, char * &str2) specify in the swap function? they specify that parameters are of type reference to pointer to char. This means that function might change the value of the variable that was provided as argument to this function. What if they are replaced by (char &str1, … Read more
[ad_1] As indicated error message, UDPCom.sendLTDimples is non static function. So you will have to create a new object of class UDPCom and then using that object call the function. UDPCom obj = new UDPCom(); Obj.sendLTDimples(); 7 [ad_2] solved in a C# script, i am getting object reference [closed]
[ad_1] The obvious way: Picture temp; temp = Picture1; Picture1 = Picture2; Picture2 = temp; [ad_2] solved Re-referencing objects
[ad_1] I can see why you’re having trouble with this pointer variable: it isn’t one. It is a reference. You cannot have a non-const reference to a const thing. That would violate the const, and allow the n = 11 line to succeed, thus again violating the original const. const means “I cannot and will … Read more
[ad_1] You don’t need to use ref in your parameter declarations. For reference types like your class A, a parameter declared as just A other will cause C# to pass a reference to the object. A parameter declared as A other in C# is similar to A* other in C++. A parameter declared as ref … Read more
[ad_1] java.util.Date, like a lot of other classes in the JDK, overrides toString(), which allows you to control the string representation of your objects. You can, of course, do this for your own classes too. 1 [ad_2] solved How new Java.util.Date() works while other classes return just reference?
[ad_1] Try to replace short RangeCheck(short word, short min, short max); char* prntword(short word); bool read(short *data, bool check); with short RangeCheck(short word, short min, short max){return 1;} char* prntword(short word){return 0;} bool read(short *data, bool check){return 0;} and it should compile for you (however it may not work as you expect) [ad_2] solved Undefined … Read more
[ad_1] This code int∗ p = &a[2]; is equivalent to this: int∗ p = a + 2; so even mathematically you can see that p – a is equal to a + 2 – a so I think result should be obvious that it is equal to 2. Note name of array can decay to … Read more
[ad_1] The only reason a function should accept a std::shared_ptr as a argument is if it may need to share or modify the ownership of the resource. If not, don’t pass a std::shared_ptr. If the function will definitely need to take shared ownership then it should accept a std::shared_ptr by value. Only accept a std::shared_ptr& … Read more
[ad_1] You’re right, C does not support passing by reference (as it is defined by C++). However, C supports passing pointers. Fundamentally, pointers are references. Pointers are variables which store the memory address at which a variable can be located. Thus, standard pointers are comparable C++ references. So in your case, void Foo(char *k, struct_t* … Read more
[ad_1] The value is passed by value to the Add method; however, if you pass a reference type (a class is always a reference type), then the value itself is a reference. So the question is not so much whether the value is passed by value or by reference, but if the type is a … Read more
[ad_1] Arrays are used to store primitive values and objects. For example, we can create an array of String or any class objects. To explain, Lets create a class Employee containing a single instance variable empId. Following is the definition of this class. class Employee{ int empId; } An array of objects is created just … Read more
[ad_1] The ampersand & probably comes from the CLR name of the type. It indicates that it is a ByRef version of the type. Did you get the Type with reflection from a method parameter decorated with the ref or out keyword? Example: var t1 = typeof(double); Console.WriteLine(t1); // “System.Double” var t2 = t1.MakeByRefType(); Console.WriteLine(t2); … Read more
