That's a complete surpise to me! I should absolutely fix it.
BTW Did you give a try to either:
(a) Avoiding duplicate insertions, as suggested by Rajesh
or
(b) Eliminate the duplicate items, as suggested by Me
?

You could use a hashtable to filter out the dups. Like CMapStringToString (if you are using MFC).

As Rajesh said - the best way is to avoid adding duplicates.
Well, if something is blocking you from that, you could use stl::set[^] to remove duplicate entries. Well, you have to pay penalty for performance.

m_ListCountries.AddString(FindFileData.cFileName);
m_tree.InsertItem(FindFileData.cFileName);

Could you please re-post the code snippet enclosed in "Code Block" so that it will be more easier to read.

Well, in the code, Which item do you want to be unique? Being more specific will fast up the responses.

While creating a service you need to specify the flag
SERVICE_INTERACTIVE_PROCESS or Open services.msc and goto the logon tab and check "Allow service to interact with desktop" checkbox.

You really should avoid showing ANY user interface in a Windows Service, they typically run when no one is logged in so there is no-one at the PC to either see the UI or use it.
Also, as a Service usually runs as a different user account to the currently logged on user they will not see the UI anyway, especially in Vista when they use a special desktop.

Windows Vista and Windows Server 2008 no longer permit interactive UI on the user's desktop. More information[^].

DeleteString() Deletes a string from a list box.
DeleteItem Called by the framework when the user deletes an item from an owner-draw list box.
Somethings seem HARD to do, until we know how to do them.

you need to pass the index of the item you want to delete. you are passing the string itself which is not intended to be the parameter type to DeleteString()

Please, next time you have a problem like this, first make sure you have read the documentation on MSDN, it is clearly explained how you have to use the function.

1. Please use inline code button instead of your custom [code][/code] tags.
2. Use CListBox::DeleteString [^]to delete a list box item.

Does the MFC/some other icon shows alongwith your application name in the task manager?

Are you sure you changed both the 32x32 and 16x16 icons in your application
