your means is this:

BOOL CDlg::PreTranslateMessage(MSG* pMsg) 
{
    if (pMsg->message == WM_MOUSEMOVE)
    {
        SendMessage(WM_USERMOVE,0,0); // how to deal with this line? 
    }	
    return CDialog::PreTranslateMessage(pMsg);
}
-------------
LRESULT CMap::OnUserMove(WPARAM wp, LPARAM lp) 
{
    // i need to RelayEvent,but how can i get the pMsg? how to use wp or lp?thank u again.
    m_tooltip.RelayEvent(pMsg);    
	
    return TRUE;
}

You can use the GetCurrentMessage function.

hi,
is your question how to get the information of "pMsg"?
there are two method, maybe answer your request.
1. refer to 'sendmessage' function, it can take information of msg to receiptor like that:
" sendmessage(WM_xxx, wp,lp);"
then , in function "OnusrMove(wp,lp)", you use the parameter of 'wp/lp' to do something.

2. in ' pretranslatemessage' function, call the process 'mousemove' straight.

hi,
thanku for your reply,but another problem again...
1.the pMsg is MSG* type,and wp or lp is DWORD type, is this can convert to each other?
2.in Pretrans...,can i do like this? -->

... ::Pretrans..(MSG* pMsg)
{
if( ... == wm_mousemove)
{
CMyChildDlg.m_tooltips.RelayEvent(pMsg); // is this ok?
}
...
}

thanks again!

hi,
1. read the structure of msg in detail,
typedef struct tagMSG {
HWND hwnd;
UINT message;
WPARAM wParam;
LPARAM lParam;
DWORD time;
POINT pt;
#ifdef _MAC
DWORD lPrivate;
#endif
} MSG, *PMSG, NEAR *NPMSG, FAR *LPMSG;

wp is pMsg->wPar...
lp is pMsg->lP...

2. maybe yes, i did't check this code. you try to test it.

hi,

1. for pMsg, there are some other params, just only send/post wp and lp can resolve the problem?

2. ok, i will test it.but cannot now.

thank u again!

Hi,

You can use Install Shield.

You can Create one new Setup Project in Visual Studio.

Incorrect binary path set during Win32 Service installation

Member 569752116-Nov-08 16:00

Member 5697521

16-Nov-08 16:00

All,

When I install my Win32 Service using CreateService() I am utilizing a TCHAR string (szPath) to input the full path to the service executable. However, when the service is installed instead of inputting this path to the executable it is inputting the path to the service installation executable that this code resides in.

Can someone explain to me why this would be happening?

Thanks

TCHAR szPath[MAX_PATH] = (L"\"C:\\Program Files\\Temp.exe\"");
TCHAR szStartName[50] = (L"Domain\\User");
TCHAR szStartNamePassword[50] = (L"**********");

schService = CreateService(
schSCManager,
SVCNAME,
SVCNAME,
SERVICE_ALL_ACCESS,
SERVICE_WIN32_OWN_PROCESS,
SERVICE_AUTO_START,
SERVICE_ERROR_NORMAL,
szPath,
NULL,
NULL,
NULL,
szStartName,
szStartNamePassword);
