In my list control I have in place edit control.
On killfocus event of edit control I am validating the text.
My requirement is when clicking on scrollbar of listcontrol I should validate with old text(it should behave like esc key )
In my application when clicking on scrollbar of listcontrol the killfocus event of edit control getting triggered and the text is getting validated with current text.
How to validate with old text?
Thanks.
As you receive a LVN_BEGINLABELEDIT you also receive a LVN_ENDLABELEDIT notification. Return TRUE or FALSE according your needs.

I have a function that I'm using to grab properties of a widget when a user changes it's input for undo/redo functionality. I have entries connected such that when a user clicks on them (focus-in-event), the current text is taken and stored. However, I've been having a big problem trying to do this with a file chooser or file chooser button. For some reason, when I click the button or chooser, and I have my handler wired to the focus-in-event signal, the filename is not grabbed. I'm not sure how to grab this value before the user changes it. I'm using glade to attach handlers to signals. Thanks!
You can achieve this by calling the get_filename method within a selection-changed callback. The response signal runs when the ok, or cancel button is clicked, and can be used to set or update which file/folder is selected to perform actions on.
First of all: I'm using C++ and ATL+WTL.
I am trying to handle the WM_KEYDOWN for an edit control that is on a page of a modal property sheet. I'd like to get the VK_NEXT key while VK_CONTROL is down. Without success so far, I only get VK_NEXT if VK_CONTROL is not down. The modal property sheet seems to eat this combination, it is used to cycle through the tabs in a standard property sheet. I have already tried to let the edit control handle WM_GETDLGCODE and return DLGC_WANTALLKEYS but still don't get this combination. However if I use modeless property sheet everything works fine (property sheet does not handle Ctrl+PageDown and edit control receives those keys). In my application I don't want to make a modeless property sheet.
So the questions is: Is there any way to handle those keys (VK_CONTROL + VK_NEXT) in edit control placed on modal property sheet?
Can anybody tell me, if I select an item in tree control than how I'll get that text in List control at the same time. I am getting how to do it?
Please help me out.
When a CTreeCtrl has an item selected, there is a WM_NOTIFY notification of TVN_SELCHANGED - See MSDN for details.
As it also says in MSDN :
As the user interacts with the control, it will send various
notification messages. You can specify a function to handle each of
the messages you want to handle by adding an ON_NOTIFY_REFLECT
macro in your control window's message map or by adding an
ON_NOTIFY macro to your parent window's message map.
If you do this, you will detect the clicked item, from which you can retrieve the text and add an entry to a list (or whatever else you need to do).
I'm trying to understand the listbox notification LBN_SELCANCEL. MSDN says "Notifies the application that the user has canceled the selection in a list box." OK, but how exactly does a user "cancel the notification"? I've got LBS_NOTIFY set, and I've tried selecting another item, clicking outside the listbox, clicking another window, and none of these trigger LBN_SELCANCEL.
Anyone know what specifically triggers this notification?
I believe LBN_SELCANCEL only applies to ComboBox controls because they also use lists.
It should be called when you open the drop down hover over an element then press ESC.

Have you tried using onFocus() handler? It will also pick up events when the user tabs into the control as well.
