Hi,

Another question:

I'd like to know whether there's a way to get the cursor's position (the flickering vertical "line") in a chat window, and setting a window's position to the cursor's (like Plus! does when "/" is the 1st character).

I have once read about the 2nd, but never about the 1st..

Greetz..

Where do you mean? In the chat window, you have the history area (where the sent and received messages are) and the typing area (where you type your messages).

For the first one, there are ChatWnd.HistoryText_GetCurSelStart() and ChatWnd.HistoryText_GetCurSelEnd() functions which let you get the current selection in the history. However, it is not possible to set the selection there.
For the second one, you can use ChatWnd.EditText_GetCurSelStart() and ChatWnd.EditText_GetCurSelEnd() to retrieve the selection and use ChatWnd.EditText_SetCurSel(Start, End) to set it.

Note: if the start and end of a selection are equal, it means that the typing cursor is at that position and has nothing selected. That's what your flickering vertical line is.

Although I don't really understand what you mean with "setting the window's position to the cursor's"...

What  mean is: Plus! opens a window with the commands at the cursor's position in the typing area, as soon as "/" is typed (as long as its character index ix 0). I'd like to do the same (using OnEvent_ChatWndEditKeyDown). Here for, I need the cursor's X and Y position. Is there a way to get it? I think it'd be something like this:

code:

---

Interop.Call(DllName,"GetCursorPos",ChatWnd.Handle);
//DllName is probably the name of some system DLL like User32.dll or something

---

GetCursorPos refers to the position of the mouse pointer, not the writing cursor thingy.

Okay... Now I need the writing cursot's position. Is there a way to get it?

Actually, it's very tough to do this. You'd have to know the font face and font size and the size of the typing area itself to calculate the size of the text and find the position of the typing cursor. Plus! does this pretty good with the Quick Emoticons menu, but there are no script features available to achieve this with a simple Plus! script.

Maybe you should talk to Patchou and ask how you could do it?

Okay

Would Plus! call a DLL to locate the writing cursor? (Sorry, but contacting Patchou is the last thing I would do.. To prevent me from flooding his mailbox )

Hmm.. So you think I should figure out how big the rectangle of the typing area is (this data is probably somewhere not in the registry..), do let some maths do their job and set the window's position?

To get the Caret position you can use the GetCaretPos. Now this is in relation to the Caret position in the text box you are typing in now the screen.

The IMConvInputHeight2 key located in the registry (HKEY_CURRENT_USER\Software\Microsoft\MSNMessenger\PerPassportSettings\1959057673) tells you the height of the input box.

code:

---

var prePOINT = Interop.Allocate;
var newPOINT = Interop.Allocate;

MsgPlus.AddTimer('x', 100);

function OnEvent_Timer(sTimerId) {
    Interop.Call('user32', 'GetCaretPos', newPOINT);
    if ( newPOINT.ReadDWORD(0) !== prePOINT.ReadDWORD(0) || newPOINT.ReadDWORD(4) !== prePOINT.ReadDWORD(4) ) {
        Interop.Call('kernel32', 'RtlMoveMemory', prePOINT, newPOINT, 8);
        Debug.Trace('x : '+newPOINT.ReadDWORD(0)+'\ty: '+newPOINT.ReadDWORD(4));
    }
    MsgPlus.AddTimer('x', 100);
}

Right... Your piece of code looks quite.. advanced and difficult to me... I have learnt, though, that Plus! places the command helper at one specific position (not next to the cursor), so in fact I only have to get the width and height of the inpt area..

But then there's part 2 of my question: how to alter a window's position?

What you are trying to do is going to be imperfect at best because it is impossible to get the exact position of the controls unless you use the MSNCore.dll file to read the DirectUIHWND control to find the exact positions.

Okay.. I am going to try and use you code anyway.. But I need some function to set a window's position. I know it's in some system DLL, because I have once read about it, but I just don't know where to find it. Is there anyone who does?

You are talking about MoveWindow
Use it like
Interop.Call('user32', 'MoveWindow', /*....its parameters here */ );

Yes Thanks lads

EDIT::

I already knew how to use it (doesn't happen ofetn ), but thanks anyway
