C / C++ / MFC

LRESULT MyComboBox::WindowProc(UINT message, WPARAM wParam, LPARAM lParam)
{
	switch((int)LOWORD(wParam))
	{
		case CBN_DROPDOWN:
			fn1();
			break;
	}
	
	return CComboBox::WindowProc(message, wParam, lParam);
}

This message is sent when the list box of a combo box is about to be made visible. <br>The parent window of the combo box receives this message through the <code>WM_COMMAND</code> message. 

array1.Copy( (CObArray*)array2.GetAt(0)); I should have been doing *(CObArray*) instead.

class base
{
protected:
	base(int n, bool b);
};

class myclass : base
{
public:
	myclass();
		
};

myclass::myclass():base(1,true){}

I couldn't find any documentation telling me I couldn't do it that way, but it was definately causing problems.

void main( void )
{
    C c1;
    C c2(1);
    C c3(2, TRUE);
}

class A {
	public A(int a, int b, int c) {
		// some ...
	}
	public A(int a, int b) {
		this(a, b, 0);
	}
	public A(int a) {
		this(a, 0, 0);
	}
}

much less fully implemente

CClass::Class()
{
   int iDefault = 1000.0f;
   *this = Class( iDefault );
