declare a static constructor, which initializes static members of the type. Static constructors are parameterless. If you don't provide a static constructor to initialize static fields, the C# compiler initializes static fields to their default value as listed in theDefault values of C# types...
// C2280_uninit.cpp// compile with: cl /c C2280_uninit.cppstructA{constinti;// uninitialized const-qualified data// members or reference type data members cause// the implicit default constructor to be deleted.// To fix, initialize the value in the declaration:// const int i = 42;} ...
The default constructor is only auto-generated if there is no user-declared constructor, hence it's impossible to initialize the vectorvd1in the example above. The absence of a default value can cause surprises for users and complicate its use, so if one can be reasonably defined, it should...

ALIGN_CENTER (Default) Aligns the button text to the center of the button. ALIGN_LEFT Aligns the button text to the left side of the button. ALIGN_RIGHT Aligns the button text to the right side of the button. The CMFCButton constructor initializes this member to ALIGN_CENTER. CMFCButton...
