为什么两个不同的button ID码相同

怎么让id1和id的值不相同？ 我现在不管按下but 还是 but1，都执行if 下的内容，而不执行else下的内容。 大神求助！！！！！！！

LONG WINAPI GetWindowLongW( __in HWND hWnd, __in int nIndex); 第二个参数是重点。。。

引用 4 楼 shen_wei 的回复:

LONG WINAPI GetWindowLongW( __in HWND hWnd, __in int nIndex); 第二个参数是重点。。。

那请问如何改第二个参数值呢？

//
HWND CreateBT(HWND parentWnd,int x,int y,int wid,int hei,UINT ID)
{
	HWND hBt=0;
	char prompt[40];
	hBt = CreateWindow("BUTTON",
                NULL,
                WS_CHILD|WS_TABSTOP|WS_VISIBLE|BS_PUSHBUTTON|WS_SIZEBOX|WS_GROUP,
                x,y,wid,hei,//180, 340, 60, 30, 
                parentWnd, (HMENU)ID,//
                (HINSTANCE) GetWindowLong(parentWnd, GWL_HINSTANCE), 
                NULL);
	sprintf(prompt,"Bt-%d",ID);
	SetWindowText(hBt,prompt);
//
	return hBt;
}

注意 (HMENU)ID,就是控件ID 因为 按钮不会有 Menu 菜单

你这里GWL_ID相同，获取的id是一样的，因为这个缘故？把另外一个GWL_ID改成GWL_ID1试试

留意 CreateWindow 的 hMenu 参数 hMenu Handle to a menu, or specifies a child-window identifier depending on the window style. For an overlapped or pop-up window, hMenu identifies the menu to be used with the window; it can be NULL if the class menu is to be used. For a child window, hMenu specifies the child-window identifier, an integer value used by a dialog box control to notify its parent about events. The application determines the child-window identifier; it must be unique for all child windows with the same parent window. 用 IDM_XXXXXX
