Drop-down Combo Box - index number of selected item

[Walls]

Hi All,

Is there a way for winbatch to return position or index number of the selected item in the Drop-down Combo Box?

In my example script below, I have Tom listed twice in the varible StrDropList. When I select the second instance of Tom, I get the index position of the first instance of the name Tom using ItemLocate (I assume this is expected behavior). I need the selected name position, not the first one it comes to that matches the string.

Thanks!

Sorry, I am not following your response or I may not be asking the question the best way.

Is there a DialogControlGet that returns the selected Item from the Drop-down Combo Box? Using "ItemLocate" is similer to what I am trying to accomplish. Using the example I submitted in the other post, If I have the same name twice in the drop down, and select the second one, I need its position in the list returned.

In my ongoing effort to completely confuse all WinBatch users, I replaced the previous response with this one.

You need to specify the @csListOnly style for your Combo control unless you don't want a potential user to enter something that has no index.  Then you need to make each entry unique which is a fairly trivial task.  Just prepend or append a number to each entry.  For example,

Code (winbatch) Select Expand

; Given this control contents
"1) Tom":@Tab:"2) Bob":@Tab:"3) Tom":@Tab:"4) Ray"
;do this in your event.
strSelected = DialogControlGet(ComBo_Handle, "DropListBox_1",@dcSelect)
Index = ItemExtract(1, strSelected, ')')

which embeds and extracts the index in the text.

Or you could consider using a different dialog control.

One option is a CommControl Extender I wrote.  I think it will do what you are wanting.   Here is a link.

Thanks TD! This is much more clear. Also, thanks JTaylor as well for the offer of the additional extender.

Jim's post reminded me that you could also just use the following in your event case to get the zero-based index of the selected item:

Code (winbatch) Select Expand


         CB_GETCURSEL = 327
         hWnd = DialogControlGet(Combo_Handle, "DropListBox_1",@dchWnd)
         Index = DllCall('user32.dll', long:'SendMessageW', long:hWnd, long:CB_GETCURSEL, long:0, long:0)


Note that "Combo_Handle" is the dialog's window handle and not the "DropListBox" window handle.
