Hello all, I am trying to disable the close button of a third party console application that I am invoking through LabVIEW. I tried using GetSystemMenu() and DeleteSystemMenu() from user32.dll, but somewhere I am doing it wrong. Can anyone can suggest a solution to this? Thanks! FraggerFox

Do you have the handle to Window? Off hand, I don't know how to delete it, but here is some C# code that I used to grey out the close window button in another project: [DllImport("user32.dll")] private static extern IntPtr GetSystemMenu(IntPtr hWnd, bool bRevert); [DllImport("user32.dll")] private static extern bool EnableMenuItem(IntPtr hMenu, uint uIDEnableItem, uint uEnable); private const Int32 SC_CLOSE = 0xF060; private const UInt32 MF_BYCOMMAND =0x00000000; private const UInt32 MF_ENABLED = 0x00000000; private const UInt32 MF_GRAYED = 0x00000001; private const UInt32 MF_DISABLED = 0x00000002; private void EnableClose(bool enable) { IntPtr pSysMenu = GetSystemMenu(Handle, false); if (pSysMenu != null) { EnableMenuItem(pSysMenu, SC_CLOSE, MF_BYCOMMAND | (enable ? MF_ENABLED : MF_DISABLED)); } } This was fairly easy to convert over once I had the handle (this is from a library I picked up somewhere). Hope this helps. A

Solved!

Otherwise you need to make an console app like I said before that disables the Ctrl-C/Ctrl-Break and then calls that app you are wanting.
