How can i interact with the chat window's history control doing things like clear it or clear just the last message or write message without name of his sender or just display message without the name of the sender when a ChatWndReceiveMessage events have been fired.thx for your help and have a nice day

It isn't possible with scripting alone. While Plus! provides Win32 API functionality I am pretty sure such a feat is impossible via the standalone scripting engine.

You are going to have to do some low level programing within Windows Live Messenger's process pages to get the real handle of the chat history control since each control is wrapped in a DirectUI wrapper. Plus! doesn't even have a /clear command so goodluck with that

that's exactly what i search for how to get the idcontrol using a dll and how use this id to interact with the control.i dont know why it's isnt included like thus interesting fct in plus! knowing we can make a lot of interessting  thing with it.

A handful of people here have the knowledge of hooking the process pages of the application. The publically known way is using ActiveAccessibility but this will only give you the handle to read the contents of the chat history box but it is readonly.

matty's reply to Active Accessibility for incoming messages

there  function included in plus! return a portion of history HistoryText_GetTextRange readonly

There are only 3 readonly functions in Plus! to deal with the chat history.

HistoryText_GetTextRange
HistoryText_GetCurSelEnd
HistoryText_GetCurSelStart

None of these will let you clear the chat history. Like I said you are going to have to hook the inner workings of WLM to get the true handle of the rtf box. This is beyond the scope of what a script can offer as far as functionality.

sorry and thx for information and please if u have any news or thing can help me please that will very generouse from u to share with me

matt im trying to recreate your code in a C++ console application to investigate a bit further and im also interested in this method of hooks

ive got this

code:

---

HWINEVENTHOOK g_hook;

void CALLBACK HandleWinEvent(HWINEVENTHOOK hook, DWORD event, HWND hwnd,
                             LONG idObject, LONG idChild,
                             DWORD dwEventThread, DWORD dwmsEventTime)
{
    printf("called\n");
    IAccessible *pAcc = NULL;
    VARIANT varChild;
    HRESULT hr = AccessibleObjectFromEvent(hwnd, idObject, idChild, &pAcc, &varChild); 
    if ((hr == S_OK) && (pAcc != NULL))
    {
        char *classname;
        classname = (char*)malloc(15);
        GetClassName(GetParent(hwnd),(LPTSTR)classname,14);
        printf("Classname: %s\n", classname);
        if(strcmp(classname,"IMWindowClass") == 0){
            printf("found\n");
        }
   
    }
}

// Initializes COM and sets up the event hook.
//
void InitializeMSAA()
{
    CoInitialize(NULL);
    g_hook = SetWinEventHook(
        EVENT_SYSTEM_ALERT , EVENT_OBJECT_ACCELERATORCHANGE,  // Range of events
        NULL,                                          // Handle to DLL.
        HandleWinEvent,                                // callback.
        0, 0,              // Process and thread IDs of interest (0 = all)
        WINEVENT_SKIPOWNPROCESS); // Flags.
}

int main(array<System:tring ^> ^args)
{
    InitializeMSAA();
    printf("init'd\n");
        while(1);
    system("pause");
    return 0;
}

thx steve but can u be more helpful by chanse i find your post http://forums.fanatic.net.nz/index.php?showtopic=12039 but it doesnt work in devc++ i find a source file for cstring class but i still have some probleme

That sample requires the Microsoft Foundation Classes (MFC) to work correctly. You can try and replace the CString uses with standard C++ strings or perhaps std:tring.
