How to enumerate available database Services(SQLSewrver or Oracle or MySQL or PostgreSQL, etc) in a network in C#? -

-

After computing the available database service (SQL Server or Oracle or MySQL or PostgreSQL, etc.) in a network using "text" itemprop = "text">

C # How To?

I also need to find my port number and service-instance names.

For example: 

  class server {#region DLL Inports [DllImport ("Odbc32.dll")] Private static extension short sql aloch handley (lower html, intupet input handles , Out InterPTR Output Handle); [DllImport ("odbc32.dll")] Private static extern short SQLSetEnvAttr (IntPtr henv, int attribute, IntPtr valuePtr, int strLength); [DllImport ("odbc32.dll")] Private Static Extern Small SQLFreeHandle (Small HType, IntPtr Handle); [DllImport ("odbc32.dll", charset = CharSet.Ansi)] Personal Stable Execution Less SQLBrowseConnect (IntPtr hconn, StringBuilder inString, Short inStringLength, StringBuilder outString, Short outStringLength, Out of Line OutLengthNeeded); #endregion #region constants personal const less SQL_HANDLE_ENV = 1; Private Context Small SQL_HANDLE_DBC = 2; Private Const is SQL_ATTR_ODBC_VERSION = 200; Private Constant SQL_OV_ODBC3 = 3; Private Context Small SQL_SUCCESS = 0; Private Context Small SQL_NEED_DATA = 99; Private contact less DEFAULT_RESULT_SIZE = 1024; Private constring string SQL_DRIVER_STR = "Driver = SQL Server"; #endrian # number static string [] GetServers () public static string [] GetNames () {string [] retval = null; String txt = string.Empty; IntPtr henv = IntPtr.Zero; IntPtr hconn = IntPtr.Zero; StringsbilderInstring = new stringbilder (SQL_DRIVER_STR); Stringbuilder outstretching = new string builder (DEFAULT_RESULT_SIZE); Small inStringLength = (short) inString.Length; Small lenNeeded = 0; Try {if (SQL_SUCCESS == SQLAllocHandle (SQL_HANDLE_ENV, henv, out henv}} {if (SQL_SUCCESS == SQLSetEnvAttr (henv, SQL_ATTR_ODBC_VERSION, (IntPtr) SQL_OV_ODBC3, 0)) {if (SQL_SUCCESS == SQLAllocHandle (SQL_HANDLE_DBC, henv, out Hconn)) {if (SQL_NEED_DATA == SQLBrowseConnect (hconn, inString, inStringLength, outString, DEFAULT_RESULT_SIZE, outside lenNeeded)} {if (DEFAULT_RESULT_SIZE & lt; lenNeeded) {outString.Capacity = lenNeeded; if (SQL_NEED_DATA = SQLBrowseConnect (hconn, inString , InStringLength, outString, lenNeeded, outside lenNeeded!) {New ApplicationException Throw ("SQL server could be obtained from ODBC driver.");}} Txt = outString.ToString (); Int start = txt.IndexOf (" ") + 1; Int len ​​= txt.IndexOf ("} ") - Start; if ((start> 0) & amp; amp;; (lane> 0)) {txt = txt .Substring (Start, Lane);} and {txt = string.Empty;}}}}}} hold (ex before) {// throw away any errors if we are not in debug mode // # (debug) //MessageBox.Show (Ex.Message, "Acquire SQL Error in Sourver List"); // # endif txt = string.Empty; East; } Finally {if (hconn! = IntPtr.Zero) {SQLFreeHandle (SQL_HANDLE_DBC, hconn); } If (Henv! = IntPtr.Zero) {SQLFreeHandle (SQL_HANDLE_ENV, HCNN); }} If (txt.Length & gt; 0) {retval = txt.Split (",". ToCharArray ()); } Return refund; } #endregion}

This code works only for SqlServers and up to Windows XP.

For other DBMS servers and does not work on Win7.

I need a canonical solution

You also use class for this can do. Keep in mind, this is MS SQL Server specific ... 

  var results = SqlDataSourceEnumerator.Instance.GetDataSources (); Foreach (var row in results.Rows) {Console.WriteLine ("{0} \ {1}", line ["server name"], line ["instance name"]); }

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...

PHP - get image from byte array -

-
I am trying to create a back-end for my mobile application. I am sending the content of an image in the body of the HTTP request (output stream) as a byte array, I want to read this stream of bytes in PHP scripts and take back an image. Can anyone tell me how can I do this? Thank you. You can obtain the request body $ body = Reading from file_get_contents ('php: // input'); What you do with that data Depending on you, you can write the data in a file as you mentioned that this is image data, you can drop the data into the object can do. Another option is to use and load the image.

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...
