是什么程序？我没遇见过这种情况

translate OnVScroll function and dispatch WM_MOUSEWHEEL message

[zhuwenzheng]

But i can not find Scrollbar using spy++

[kingzai]

derive your view class from CScrollView

[kingzai]

and if your window version is NT4,padding service pack 6

[zhuwenzheng]

to kingzai() :
能不能说详细点啊，或者有源程序

[kingzai]

//CAaView is derived from CScrollView
BOOL CAaView::OnMouseWheel(UINT nFlags, short zDelta, CPoint pt)
{
AfxMessageBox(_T("test"));
return CScrollView::OnMouseWheel(nFlags, zDelta, pt);
}
//i have not test OnHScroll or OnVScroll function

我是写鼠标驱动的，我已经收到了鼠标的Z值 ，怎么样使得滚轮滚动呢？

[zhuwenzheng]

kingzai兄：
你误解我的意思了，我的意思是有的软件没有滚轮功能，怎么加上这个功能？

[kingzai]

get process main window handle,and send WM_MOUSEWHEEL message to it.
try it.

kingzai:
我知道发送WM_MOUSEWHEEL消息，但是怎么使得滚动条动呢？
SendMessage(hwnd,WM_MOUSEWHEEL,0,0);


...
case WM_MOUSEWHEEL:
//here i dont know how to do & how to connect the scrolling bar

[wistaria]

1. Register the MSH_MOUSEWHEEL message. Copy the following line to your Cyour.cpp file:
AFX_STATIC UINT _afxMsgMouseWheel =
(((::GetVersion() & 0x80000000) && LOBYTE(LOWORD(::GetVersion()) == 4)) ||
(!(::GetVersion() & 0x80000000) && LOBYTE(LOWORD(::GetVersion()) == 3)))
? ::RegisterWindowMessage(MSH_MOUSEWHEEL) : 0;


2. Add this line to your class' message map after the AFX_MSG_MAP section:
ON_REGISTERED_MESSAGE(_afxMsgMouseWheel, OnRegisteredMouseWheel)

3. Add a member function called OnRegisteredMouseWheel passing a WPARAM and LPARAM and returning LRESULT to your class. Add the following code in the function definition (code taken from Winfrm.cpp):

LRESULT CYourView(or CYourDialog)::OnRegisteredMouseWheel(WPARAM wParam, LPARAM lParam)
{
// Convert from MSH_MOUSEWHEEL to WM_MOUSEWHEEL.

WORD keyState = 0;
keyState |= (::GetKeyState(VK_CONTROL) < 0) ? MK_CONTROL : 0;
keyState |= (::GetKeyState(VK_SHIFT) < 0) ? MK_SHIFT : 0;

LRESULT lResult;
HWND hwFocus = ::GetFocus();
const HWND hwDesktop = ::GetDesktopWindow();

if (hwFocus == NULL)
lResult = SendMessage(WM_MOUSEWHEEL, (wParam << 16) | keyState, lParam);
else
{
do {
lResult = ::SendMessage(hwFocus, WM_MOUSEWHEEL,
(wParam << 16) | keyState, lParam);
hwFocus = ::GetParent(hwFocus);
}
while (lResult == 0 && hwFocus != NULL && hwFocus != hwDesktop);
}
return lResult;
}
