Thanks for your reply. Thats a good suggestion I appreciate it. But I don't want to restrict use from entering value like ALT + 65 , ALT + 117 which is valid value Actualy I am sending this value to COM object as BSTR. That is where I have my business logic written to validate the data entered. So I wanted to first figure out how to do it in C# and then mimic the similar code in C++. I found one website where they have table to show DOS equalent characters.

DateTime.Now.ToFileTime() returns long.. FILETIME is structure. Pls let me if you have someother idea Sandeep Naik

A deque (check the manual) is an ideal structure for this, as insertions and deletions at both ends of the sequence are very efficient (constant time, basically.) Joaquín M López Muñoz Telefónica, Investigación y Desarrollo Want a Boost forum in Code Project? Vote here[^]!

Oh yes I don't have problem with compmgmt.msc but we have our own .msc file and we lot of items in that list. And with SORT its big problem. Sandeep Naik

The column header does not shows the usual sort arrow, so I guess they have not implemented sorting on this list in Windows 2000:eek: ARSALAN MALIK

From look at Spy++, when a list control single-clicked, it receives a WM_LBUTTONDOWN message followed by a WM_LBUTTONUP message. When a list control double-clicked, it receives those two messages followed by a WM_LBUTTONDBLCLK and WM_LBUTTONUP. Can you monitor for WM_LBUTTONDOWN and WM_LBUTTONDBLCLK separately?
