看下我这个怎么销毁不了控件？

[jiaerboy]

class control{
HINSTANCE hInst;
HWND hMainHwnd;



HWND hMenu;

HWND hListView_User;
HWND hStatusBar_User;
HWND hToolbar_User;
HWND hComboboxProvince_User;
HWND hComboboxCity_User;
HWND hComboboxDistrict_User;

public:
control(HWND hwndParent);
~control();
void DestroyCtr();
BOOL CreateMenu();
BOOL CreateUserCtr();
BOOL CreateGameCtr();
};
void control::DestroyCtr(){
DestroyWindow(hToolbar_User);
}
调用DestroyCtr销毁不了hToolbar_User

那个 是不是个模式化窗口？
