You can use the LB_GETLBTEXTLEN and LB_GETLBTEXT messages to get the text of a combo box item.

RE: [REQU] Patchou PlusWnd::Combo_GetItemText not exist why? by felipEx on 06-28-2007 at 06:59 PM

how about
PlusWnd::LstBox_Clear(
[string] ControlId
);

Interop.Call("user32", "SendMessageW", PlusWnd.GetControlHandle(ControlId), 0x184 /* LB_RESETCONTENT */, 0, 0);

while mode
while (ww.Combo_GetCount("cbc")){
ww.Combo_RemoveItem("cbc",0);
}

works fine too but i like LB_RESETCONTENT, fast & short

your code not work on my combo, so
i see the w.GetControlText("cbc") return selected text on the combo good new
->
The PlusWnd::GetControlText function returns the text property of a ButtonControl, a CheckBoxControl, a RadioControl, a LinkControl, an EditControl, a RichEditControl, a RichStaticControl or a StaticControl.

but why u speak for reset the content is not my question man

i need to know the text in each line of my combo

sure... but you've suggested PlusWnd::Combo_GetItemText and i've suggested PlusWnd::LstBox_Clear

so... it works fine here

code:
var CB_GETCOUNT = 0x146;
var CB_GETLBTEXT = 0x148;
var CB_GETLBTEXTLEN = 0x149;
for (var i=0; i < Interop.Call("user32", "SendMessageW", PlusWnd.GetControlHandle("MyComboBox"), CB_GETCOUNT , 0, 0) ; i++) {
var length = Interop.Call("user32", "SendMessageW", PlusWnd.GetControlHandle("MyComboBox"), CB_GETLBTEXTLEN, i, 0);
var Data = Interop.Allocate((length * 2) + 2);
Interop.Call("user32", "SendMessageW", PlusWnd.GetControlHandle("MyComboBox"), CB_GETLBTEXT, i, Data);
Debug.Trace(Data.ReadString(0));
}

RE: [REQU] Patchou PlusWnd::Combo_GetItemText not exist why? by Flash on 06-28-2007 at 09:51 PM

i find this for combo = cb_

code:
function cb_ClrCtrl(w,d) {
//Interop.Call("user32", "SendMessageW", w.GetControlHandle, 0x14B /* CB_RESETCONTENT */, 0, 0);
w.SendControlMessage(d,0x14B /* CB_RESETCONTENT */, 0, 0)
}

}

you seem that you're working with dispatchers functions =) . why Patchou doesn't implement programming-based on prototypes ? ^^

RE: [REQU] Patchou PlusWnd::Combo_GetItemText not exist why? by Flash on 06-28-2007 at 10:23 PM

i tryed your code felip that work fine

code:
function cb_GetItem(w,d,n){
var CB_GETCOUNT = 0x146
var CB_GETLBTEXT = 0x148
var CB_GETLBTEXTLEN = 0x149
var t = w.SendControlMessage(d,CB_GETCOUNT, 0, 0)
//Debug.Trace("Total= " +t)
for(var i=0; i < t; i++) {
var length = w.SendControlMessage(d, CB_GETLBTEXTLEN, i, 0)
var Data = Interop.Allocate((length * 2) + 2)
if (i == n) {
Interop.Call("user32", "SendMessageW", w.GetControlHandle, CB_GETLBTEXT, i, Data);
//w.SendControlMessage(d,CB_GETLBTEXT,i,Data) not work
return Data.ReadString(0)
}
}
}

yes i dont know how for other way

its possible this way

code:
cb_GetItem(ww,"cbc",0) -> ww.cb_GetItem("cbc",0)

RE: [REQU] Patchou PlusWnd::Combo_GetItemText not exist why? by CookieRevised on 06-29-2007 at 12:04 AM

code:
function cb_GetItem(w,d,n){
var CB_GETCOUNT = 0x146
var CB_GETLBTEXT = 0x148
var CB_GETLBTEXTLEN = 0x149
var t = w.SendControlMessage(d,CB_GETCOUNT, 0, 0)
//Debug.Trace("Total= " +t)
for(var i=0; i < t; i++) {
var length = w.SendControlMessage(d, CB_GETLBTEXTLEN, i, 0)
var Data = Interop.Allocate((length * 2) + 2)
if (i == n) {
Interop.Call("user32", "SendMessageW", w.GetControlHandle, CB_GETLBTEXT, i, Data);
//w.SendControlMessage(d,CB_GETLBTEXT,i,Data) not work
return Data.ReadString(0)
}
}
}

- You don't need the loop.
- Inside the loop you don't need to check if the index is the same as the parameter
- w.SendControlMessage(d,CB_GETLBTEXT,i,Data) does not work because you need to give a pointer to the Data object, not the object itself: w.SendControlMessage(d,CB_GETLBTEXT,i,Data.DataPtr)

The above code can be done way shorter and much faster:

code:
function Combo_GetItemText2(pPlusWnd, sControlId, nItemIdx) {
if (nItemIdx >= 0 && nItemIdx <= pPlusWnd.Combo_GetCount(sControlId)) {
var nLength = pPlusWnd.SendControlMessage(sControlId, 0x149 /* CB_GETLBTEXTLEN */, nItemIdx, 0);
var Buffer = Interop.Allocate(nLength * 2 + 2);
pPlusWnd.SendControlMessage(sControlId, 0x148 /* CB_GETLBTEXT */, nItemIdx, Buffer.DataPtr);
return Buffer.ReadString(0)
} else {
return ''
}
}

And this can be made even more shorter and faster:

code:
function Combo_GetItemText(pPlusWnd, sControlId, nItemIdx) {
var hControl = pPlusWnd.GetControlHandle(sControlId);
var nLength = Interop.Call("User32", "SendMessageW", hControl, 0x149 /* CB_GETLBTEXTLEN */, nItemIdx, 0);
var Buffer = Interop.Allocate(nLength * 2 + 3);
Interop.Call("User32", "SendMessageW", hControl, 0x148 /* CB_GETLBTEXT */, nItemIdx, Buffer.DataPtr);
return Buffer.ReadString(0);
}

heheh Mr. CookieRevised
i has this code:

code:
function Combo_Text(PlusWnd, ControlId, Index){
var CB_GETCOUNT = 0x146;
var CB_GETLBTEXT = 0x148;
var CB_GETLBTEXTLEN = 0x149;
var CB_GETCURSEL = 0x147;

if (!Index) Index = Interop.Call("user32", "SendMessageW", PlusWnd.GetControlHandle(ControlId), CB_GETCURSEL, 0, 0);
if (Index < 0) return "";

var Data = Interop.Allocate(( Interop.Call("user32", "SendMessageW", PlusWnd.GetControlHandle(ControlId), CB_GETLBTEXTLEN, Index, 0) * 2) + 2);
PlusWnd.GetControlHandle(ControlId), CB_GETLBTEXT, Index, Data);
return Data.ReadString(0);
}

Edit.. Ohh.. you've posted before me

(Combo_GetItemText is better hehe , nice job ^^)

I think you mean:

quote:
code:
Interop.Call("user32", "SendMessageW", PlusWnd.GetControlHandle(ControlId), CB_GETLBTEXT, Index, Data);

otherwise that code, as you showed it here, doesn't make any sense at all as it is missing a big part at the beginning...

And... (when that part would have been there), your code:

- will not return the proper text for the first item in the list because of if(!Index). This is not the proper way to handle an optional parameter. If Index is 0, to get the first item of the list, then (!Index) will be -1, aka True and thus the selected item will be returned instead of the first item in the list.
To check if an optional parameter is used or not you need to do: if (typeof(myvariable) === 'undefined')

- will go bananas when you give a too high index as a parameter because CB_GETLBTEXTLEN and other messages will return CB_ERR in that case and your datablock will have a bad length.

- will go bananas when nothing is selected in the list and you request the selected item because the new Index will be CB_ERR in that case.

If you use my snippets you wont have those problems and it would also be faster.
Here is that last and shortest snippet again, but with the addition of the optional index so that you can get the current selected item also (=addition of the second line):

code:
function Combo_GetItemText(pPlusWnd, sControlId, nItemIdx) {
var hControl = pPlusWnd.GetControlHandle(sControlId);
if (typeof(nItemIdx) === 'undefined') nItemIdx = Interop.Call("User32", "SendMessageW", hControl, 0x147 /* CB_GETCURSEL */, 0, 0);
var nLength = Interop.Call("User32", "SendMessageW", hControl, 0x149 /* CB_GETLBTEXTLEN */, nItemIdx, 0);
var Buffer = Interop.Allocate(nLength * 2 + 3);
Interop.Call("User32", "SendMessageW", hControl, 0x148 /* CB_GETLBTEXT */, nItemIdx, Buffer.DataPtr);
return Buffer.ReadString(0);
}
