What would be the easiest way to have an ArrayCtrl with cells whose each of them consists of an edit field and a helper button (button caption is like "..."). An example can be seen in VC++ 2005 by going to Tools->Options->VC++ Diretories and look at the list on the right hand side.
Basically, the ArrayCtrl supports inline editing, but each cell at the time of being edited also shows a small button at the right edge.
Thanks

ok, you can try this and tell if it's what you expected.
#include <CtrlLib/CtrlLib.h>
class Ctrl2 : public ParentCtrl {
EditField edit;
Button button;
public:
typedef Ctrl2 CLASSNAME;
Ctrl2();
~Ctrl2() {;}
};
Ctrl2::Ctrl2()
{
edit.SetRect(0,0,50,15); //one problem are sizes >15...
button.SetRect(55,0,85,15);
button.SetLabel("Help!!!");
Add(edit);
Add(button);
}
void Extra2(One<Ctrl>& ctrl)
{
ctrl.Create<Ctrl2>();
}
GUI_APP_MAIN
{
TopWindow w;
ArrayCtrl arr;
arr.AddColumn("col1",2);
arr.AddColumn("col2",5).Ctrls(Extra2);
arr.SetLineCy(20);
arr.Add("aaa");
arr.Add("bbb");
arr.SizePos();
w.Add(arr);
w.Run();
}

BTW, consider using layout....

Hello,
I've modified a bit the Aris' example above using the layout as Mirek suggested to create an embedded two-control made by an editint followed by a label. What is entered in the edit is immediately replicated in the label. Here it is:
#include <CtrlLib/CtrlLib.h>
#define LAYOUTFILE <edithelp/a.lay>
#include <CtrlCore/lay.h>
//--------------------- begin class -----------------
class EditLabel : public WithEditLabel<TopWindow> {
public:
typedef EditLabel CLASSNAME;
void WriteLabel();
EditLabel();
};
void EditLabel::WriteLabel()
{ lbl.SetLabel( AsString(~edit) );
//SetFocus();
}
EditLabel::EditLabel()
{ CtrlLayout(*this, "");
edit <<= THISBACK(WriteLabel);
}
void Extra2(One<Ctrl>& ctrl)
{ ctrl.Create<EditLabel>();
}
//--------------------- end class -------------------
GUI_APP_MAIN
{
TopWindow w;
ArrayCtrl arr;
arr.AddColumn("col1",20);
arr.AddColumn("col2",20).Ctrls(Extra2);
arr.SetLineCy(20);
arr.Add("aaa");
arr.Add("bbb");
arr.SizePos();
w.Add(arr);
w.Run();
}
LAYOUT(EditLabel, 96, 19)
ITEM(EditInt, edit, LeftPosZ(2, 32).TopPosZ(1, 17))
ITEM(Label, lbl, SetFrame(ThinInsetFrame()).LeftPosZ(36, 60).TopPosZ(1, 17))
END_LAYOUT
Now the horintal alignement is improved drastically and there is no problem with size > 15 that can be tuned as one like.
Moreover appear the annoying problem of the cursor of the array that does not follow the click on the embedded control. To overcome it I've added
SetFocus();
connected to edit.WhenAction but then come two new unwanted side effects:
1) WhenAction was already used to pass the value to the label at the right. So while one type in the editint it continue to focus when should not be necessary (in principle).
2) Instead happens that after the first SetFocus() the cursor of the array is syncronised with the embedded control but the focus escape from editint and finish somewhere else in the row and one cannot continue the edit of the field!
Any idea to overcame the problem?
Luigi

Also, try to change (with the above)
WithEditLabel<TopWindow> -> WithEditLabel<ParentCtrl>
and
CtrlLayout(*this,""); -> CtrlLayout(*this);
also:
ctrl.Create<EditLabel>().SizePos();
and this:
LAYOUT(EditLabel, 124, 32)
ITEM(EditInt, edit, LeftPosZ(12, 32).VCenterPosZ(17, 1))
ITEM(Label, lbl, SetFrame(ThinInsetFrame()).LeftPosZ(64, 56).VCenterPosZ(16, 0))
END_LAYOUT

try this: 
void EditLabel::WriteLabel()
{
lbl.SetLabel( AsString(~edit) );
SetFocus();
edit.SetFocus();
edit.SetSelection(edit.GetLength());
}
btw, why do you use a label and not a button?

Thanks!
Everything work perfectly. Your improvements automatically include a feature that I wanted: each time I pressed the TAB key the focus pass to the next editint.
I need a label to show the match result [1-0], [0-1] etc..., while in the editint I enter their short code 1, 0, and so on.
Let me ask you (this is a good moment for it) what is the difference between deriving from TopWindow and CtrlParent. It seems the second one is better for embedded widget in that it merge better with the around widget. While the first one seems more indicate for indipendent widget like dialog. Is it correct?
BTW, can you add two words for the tricky row:
edit.SetSelection(edit.GetLength());
without it I can't enter more than one char.
