Create a wrapper class in a CLI project (C++.NET) and you should be able to access the C++ class from the .NET class. The advantage of this is that you keep your C++ project as is and you can debug both heaps easily. In this mode the unmanaged and managed heaps run within the same process without marshaling. I hope this helps.

HTTP stuff is contained in the System.Net[^] namespace. The WebRequest[^] class example demonstrates a typical usage scenario. :badger:

FYI you can use < (<) and > (>) in your posts instead of # That would make it a bit clearer IMO

Have a look at this for clearer picture of what all you need to do: Sending Emails using .NET Part II[^] You might had set some configuration settings too. In case not, you need to do that too. Described in the article above.

You are right, then split the file name into 2 fields when you load the listview, that will give you the granularity you need. OR use another control! Never underestimate the power of human stupidity RAH

Thank you guys .:rose: We are haven't bug,just temporarily undecided problems.

Hmm... you cannot add 4,5GB to memory, it's too big. Probably write it in a file and send the link to windows explorer.

See NTcore's Phoenix protector, it's pretty good and free However, before you do that, you should realize that it is fundamentally impossible to completely hide your code (ok you can, but then your CPU does not know what to execute either so your program wouldn't be useful anyway) So no matter what you do, people will be able to "borrow" (and/or edit) your code. But with obfuscation, the script kiddies and other noobs may give up. That's all. If you're worried about industrial espionage, your only choice is to never release your program.

You are trying to determine when Visual Studio closes the file without Visual Studio exiting? You cannot determine that using the Process class or FileSystemWatcher, or any other external component. The only way to figure that out is to write code that talks to Visual Studio itself and ask what the currently open documents are. No, I don't know how to do that.

Thanks for reply Abhinav. I see this article , but i can't find what do need me! Maybe windows have something (message , function ,...)? Anyone know how to do it ? Thanks. We are haven't bug,just temporarily undecided problems.

Hi. Yep, you are right ,i need change my logic. Thanks. We are haven't bug,just temporarily undecided problems.

Thanks, I had exactly the same problem ! Here my new code, if it can help someone esle :) \[StructLayout(LayoutKind.Sequential)\] public struct MENUITEMINFO { public uint cbSize; public uint fMask; public uint fType; public uint fState; public uint wID; public IntPtr hSubMenu; public IntPtr hbmpChecked; public IntPtr hbmpUnchecked; public IntPtr dwItemData; public string dwTypeData; public uint cch; public IntPtr hbmpItem; } public class DllImports { \[DllImport("user32.dll")\] public static extern bool InsertMenuItem(IntPtr hMenu, uint uPosition, uint uFlags, \[In\] ref MENUITEMINFO mii); \[DllImport("user32")\] public static extern UInt32 SetMenuItemBitmaps(IntPtr hMenu, uint uPosition, uint uFlags, IntPtr hBitmapUnchecked, IntPtr hBitmapChecked); } private void AddMenuItem(IntPtr hMenu, uint id, uint position, string text, Bitmap icon, IntPtr? hSubMenu) { MENUITEMINFO mii = new MENUITEMINFO(); mii.cbSize = (uint)Marshal.SizeOf(typeof(MENUITEMINFO)); //48; mii.fMask = (uint)MIIM.ID | (uint)MIIM.STRING | (uint)MIIM.SUBMENU; mii.wID = id; mii.dwTypeData = text; if (hSubMenu.HasValue) { mii.hSubMenu = hSubMenu.Value; } DllImports.InsertMenuItem(hMenu, position, (uint)MF.BYPOSITION, ref mii); if (icon != null) { DllImports.SetMenuItemBitmaps(hMenu, id, (uint)MF.BYCOMMAND, icon.GetHbitmap(), icon.GetHbitmap()); } } The biggest problem was this line : mii.cbSize = (uint)Marshal.SizeOf(typeof(MENUITEMINFO)); //48; As in all exemples you found on web, the size is set to 48 by default and not calculate. Thanks again. Decco

Writing shell extensions in anything but .NET 4.0 is not supported and highly inadvisable. You've been shown the article describing why. A guide to posting questions on CodeProject[^] Dave Kreskowiak Microsoft MVP Visual Developer - Visual Basic      2006, 2007, 2008 But no longer in 2009...
