Hi!
if I use this function on messenger 8.5 it's all OK

code:

---

var WM_CLOSE = 0x0010;
Interop.Call("user32", "SendMessageW", ChatWnd.Handle, WM_CLOSE, 0, 0);

---

Do you have Messenger Discovery Live installed? Closing the chat window like that shouldn't cause it to crash.

no, I only have installed messenger plus 4.8...

Something REALLY weird is happening.

Mine isn't crashing HOWEVER the OnEvent_ChatWndCreated function is being called twice and the chat window is being opened twice and the handle of the window is obviously different. I wonder if WLM2009 tries to open it twice. Once to open and once to bring it forward?

is probabily....
There are other ways to close the window?

news!

code:

---

function OnEvent_ChatWndReceiveMessage(ChatWnd, Origin, Message, MsgKind){
if(Message=="ok"){
Interop.Call("user32", "SendMessageW", ChatWnd.Handle, 0x0111, 40003, 0);
}
}

---

code:

---

function OnEvent_ChatWndReceiveMessage(ChatWnd, Origin, Message, MsgKind){
if(Message=="ok"){
wnd = ChatWnd
MsgPlus.AddTimer("ok",2000)
return ""
}
}

function OnEvent_Timer(TimerId){
Interop.Call("user32", "SendMessageW", wnd.Handle, 0x0111, 40003, 0);
}

Try PostMessage instead of SendMessage? Perhaps calling SendMessage within a Plus! event handler can cause unexpected troubles.

emh...
can you tell me the exact code to try?
thank

Just replace the SendMessage with PostMessage in your crash code

JScript code:

---

function OnEvent_ChatWndReceiveMessage(ChatWnd, Origin, Message, MsgKind){
if(Message=="ok"){
Interop.Call("user32", "PostMessageW", ChatWnd.Handle, 0x0111, 40003, 0);
}
}

o thank
i try it later with my PC
