對話框按鈕簡單使用實例

需要先添加對話框，并且修改確定按鈕的ID值

.h文件

struct DecodeUint{
UINT meesage;
LONG (*fun)(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam);
};

#define dim(x) (sizeof(x)/sizeof(x[0]))

LONG OnInit(HWND hDlg, UINT message, WPARAM wParam, LPARAM lParam);
LONG OnCommand(HWND hDlg, UINT message, WPARAM wParam, LPARAM lParam);
LONG OnClose(HWND hDlg, UINT message, WPARAM wParam, LPARAM lParam);
LONG OnBtnClick(HWND hDlg, UINT message, WPARAM wParam, LPARAM lParam);

BOOL CALLBACK About(HWND hDlg, UINT message, WPARAM wParam, LPARAM lParam);
