c# - XmlDocument.SelectSingleNode returns null for root node -

-

I have many XML files that do not have postfix .xml, but I want to now handle them in the C # program. But it seems that C # slang can also find the basics of these XML files 

  var doc = new XmlDocument (); Doc.Load (path); // MG: Edit XmlNode root = doc.SelectSingleNode ("rootNodename") to load on comment basis;

It seems that the root is zero, how should I face it?

Given that you have load / LoadXml Illusion has solved, I hope this issue is the name space; Do you have XML? Handling XML with names ... "Funny"; -P

For example: 

  XmlDocument doc = new XmlDocument (); Doc.LoadXml (@ "& lt; test xmlns = 'myFunkyUri' value = 'ABC' / & gt;"); // wrong; Do not consider any namespace XmlElement root = (XmlElement) doc.SelectSingleNode ("test"); Console.rootline (root == empty? ("No root)": root. GetAttribute ("value")); // Right XmlNamespaceManager nsmgr = New XmlNamespaceManager (doc.NameTable); Nsmgr.AddNamespace ("x", "myFunkyUri"); // My FUNYUURY = Root = (XMLAllment) is my nickname for the doctor. Selection Crowding Node ("X: Test", NSMGR); Console.rootline (root == empty? ("No root)": root. GetAttribute ("value"));

Note, even if your XML declares the XML nickname, you may still need to re-declare it for your namespace manager.

c# - ListView onScroll event -

-
I am programming a simple C # application, and I need a Scallow event on the list view. So I inherited the original ListView class created in ListviewEx witch. I found out how to locate the scroll message from WinAPI and I modified the WndProc method. Now I have this WndProc: protected override zero WndProc (Ref message message) {base.WndProc (Ref I); If (m.msg == WM_VSCROLL) {onScroll (This, New EventArgs ()); }} But the problem is, I do not know how to know about scrolling information. This data should be in wParam, but there is a LOWORD macro ++ like in C in C # and I switch to find the criteria like SB_ below, SB_ENDSCROLL, SB_PAGEUP etc. there any way Need to change the LOWORD macro from C #? Or any other way to find the necessary parameters about scrolling? You can define the WParam constants as the following: Private const int WM_HSCROLL = 0x114; Private Constant WM_VSCROLL = 0x115; Private contact int SBHOZZ = 0; Private Consultant SB_VERT = 1; Private Con...

Linux Terminal Problem with Non-Canonical Terminal I/O app -

-
I have a small app written in C to run on Linux. Part of the app accepts user-input from keyboard , And it uses non-canonical terminal mode so that it can respond to each keystroke. The section of the code that accepts input is a simple task that is called repeatedly in the loop: char get_input () {char C = 0; Int res = reading (input_tamille, & amp; c, 1); If (RSS == 0) 0 returns; If (res == -1) {/ * snip error handling * /} return c; } It reads a letter from the terminal if there is no input within a given time limit, (c_cc [VTIME] value in the vocabulary structure), read () 0 And get_input () is called again It all works very well, I have recently discovered that if you run this app in a terminal window, and then the app Close the terminal window without ending, the app will not exit Received, but CPU intensive launches into an infinite loop, where the read () returns 0 without waiting continued. So how can I get out of the apple if it runs from the terminal win...
