If the button is in a dialog box and the dialog box is not active, the BM_CLICK
message might fail. To ensure success in this situation, call the SetActiveWindow
function to activate the dialog box before sending the BM_CLICK message to the button.

or replaced BM_CLICK with BN_CLICKED,

#pragma pack (1)
class A
{
   int a;
   char b;
};
#pragma pack (1)

if you have to save some memory from the object size, better rearrange the members order first.

struct STest
{
    DWORD   m_dwValue;
    char    m_cValue;
};
struct STest2
{
    DWORD   m_dwValue;
    char    m_cValue;

struct STest3

    char    m_cValue;
