因为子文件中引用主程序定义的结构体出错。解决:将子程序文件中 子函数移至主文件。结构体也是一种数据类型，只不过在这种数据类型中又包含了几个基本的数据类型。构体变量在内存中的存放和基本数据类型变量在内存中的存放是不同的，基本数据类型的存放系统是会给分配一块连续的空间用来存放，而结构体...
So, what I've been trying to do is after declaring a member of type C, to access an inherited function from B which has access to C's data struct. A void pointer wouldn't do the job, as it cannot point to object types. I've tried passing the address of C to B, though, they...
The reason that you're able to call the function on a null pointer successfully is that your compilers don't store the function "in" the object. Rather, the above code is interpreted somewhat like this: classA{int_dmember; };voidA::func(A *this){ cout <<"Inside A!!"<< endl; co...
In the code you posted, pd points to a single PictureBoxArray. As far as pd is concerned, that is an array of one element, not eight. While a PictureBox has a member named Visible, pd points to a PictureBoxArray which is a different type of object than a PictureBox. Look at how...

This package has a bug of some kind that causes crashes in the Go runtime under heavy use. To reproduce, add the following to intern_test.go: func TestTorture(t *testing.T) { // Get the same Value over and over again, while the GC runs i...
