按鈕的本質就是窗口

按鈕的WNDCLASS不是我們定義的，是系統預定義好的。如果我們想知道，系統預定義的WNDCLASS都包含什麼樣的信息

點擊查看代碼

TCHAR szBuffer[0x20];					
GetClassName(hwndPushButton,szBuffer,0x20);					
					
WNDCLASS wc;					
GetClassInfo(hAppInstance,szBuffer,&wc);					
OutputDebugStringF("-->%s\n",wc.lpszClassName);					
OutputDebugStringF("-->%x\n",wc.lpfnWndProc);					
					

逆向分析
1.找到入口
2.找到關鍵函數 定位信息循環
3.定位關鍵的按鈕
