Is there any way I can get the position of the text cursor in a text box in a plus interface?

I need to insert some text at the current cursor position instead of at the end of the box which is the way I'm currently doing it.

Thanks,
David

you can send the EM_GETSEL message. In version 4.21, some new functions have been added to add more support for edit controls.

Would it be possible for you to give me some guidance on how to do this please? Maybe just a little example to get me started.

Hi Patch.
you would have to consider the use of <MaxLength>   

it can be possible with API.

code:

---

var EM_LIMITTEXT = 0xC5;
Interop.Call("user32", "SendMessageW", PlusWnd.GetControlHandle("mytxt"), EM_LIMITTEXT, 11 /* or new maxlength value */ , 0);

---

Well I've figured out the EM_GETSEL message and it's working fine now. I'm onto the string processing part now, and I'm getting this error:

Error: Object doesn't support this property or method.
       Line: 40. Code: -2146827850.

This is the code, the middle line is line 40:

code:

---

var text = Wnd.GetControlText("NameEdit");
var firstHalf = text.substring(0, Start);
var secondHalf = text.substring(Start, before.length);

---

I'm assuming it's talking about the substring method, but I don't see why it's saying it's unsupported... any ideas?

Thanks,
David

what is $Start defined as?

Here is the code that defines start:

code:

---

var EM_GETSEL = 0xB0;
var EM_SETSEL = 0xB1;
var Start = Interop.Allocate(32);
Interop.Call("user32", "SendMessageW", Wnd.GetControlHandle("NameEdit"), EM_GETSEL, Start, 0);

When you are allocating memory to a variable you cannot simply reference the variable itself. In this case the value you are trying to read is a DWORD.

You need to replace:

code:

---

var text = Wnd.GetControlText("NameEdit");
var firstHalf = text.substring(0, Start);
var secondHalf = text.substring(Start, before.length);

---

With this

code:

---

var text = Wnd.GetControlText("NameEdit");
var firstHalf = text.substring(0, Start.ReadDWORD(0));
var secondHalf = text.substring(Start.ReadDWORD(0), before.length);

---

And where does before come into play?

Also why are you allocating 32 bytes of memory to Start? It should be 4.

Thanks a lot for that ... the before doesn't come into play, I forgot to change it to text for this example. It's all working fine now.

He never used the variable $Start. It was Start. Please don't confuse with it. This is not php that you'll need $ for a variable. This is JScript.
