怎样枚举窗体中的控件？

Question

我想列举拨号上网窗体中的控件，一共用到了GetWindow,FindWindow,GetWindowLong      
程序为：      
HWND hWnd=FindWindow(NULL,"连接 拨号连接");      
HWND hWnd1=GetWindow(hWnd,GW_CHILD);      
HWND hWnd2=hWnd1;      
do      
{      
hWnd2=GetWindow(hWnd2,GW_HWNDNEXT);      
dwStyle=GetWindowLong(hWnd2,GWL_STYLE);      
if(dwStyle & ES_PASSWORD){      
cprintf(_T(  "find a passwd edit!\n "));}      
                                             }      
}while(hWnd2!=NULL);      
可是得不到想要的“find a passwd edit”结果，无论我怎样修改都不行，请问应该怎样      
写呀？如果哪位大虾赐教，感激不尽(最好能编译通）

Answer 1

use EnumChildWindows,such as 
EnumChildWindows(hwnd,EnumChildProc,0);BOOL CALLBACK EnumChildProc(HWND hwndChild, LPARAM lParam) 
{
char temp[100];
memset(temp,0,100);
GetClassName(hwndChild, temp, sizeof(temp));
long l =GetWindowLong(hwndChild, GWL_STYLE);
         ...}

Answer 2

HWND hWnd=FindWindow(NULL,"连接 拨号连接");
HWND hwndChild = GetWindow(hWnd,GW_CHILD|GW_HWNDFIRST);
while(hwndChild != NULL)
{
   //Do your thing;
   hwndChild = GetWindow(hwndChild,GW_HWNDNEXT);
}
