c# - Sql Server 2005 localhost System DSN not working -

-

I have a C # .NET 3.5 executable which runs on the local machine and the database server to run SQL Server In 2005, I used System DSN (using a driver with SQL Server on the server) using the Data Source Manager on a local machine named "LocalServer". When I make DSN, I can successfully test the connection to the server.

I added the local connection to my connection string in my executable, and I get an error "An error occurred while establishing connection to a network related or example-specific SQL Server. Was not found or was not accessible. Verify that the example name is correct and SQL Server is configured to allow remote connection. (Provider: Nami The Pipes provider, Error: 40 - does not open any connection to the SQL Server) "

The server connecting that allows the remote connection when I change the local names to the server name, this fix , But this program will be in multiple locations with multiple server names, so I need to make the data source dynamic.

Why is such an idea

edit:

I also have "local server, 1433" my data As a source, but I get this error: "A network related or instance-specific error occurred when installing a connection to SQL Server. The server was not found or was not accessible. Verify that the name of the example is Is correct and to allow remote connections to that SQL Server Is configured (Provider: TCP provider, error: 0 - No such host is known.) "

Edit:

Your answers Thanks to, to solve my problem, I have made a small method to collect the synerm using an ODBC connection.

Then I can send the server name to the SRL connection. Thanks again for your input.

SQLAquilient (i.e. SQL Connection) is not to do absolutely anything with the ODBC such as the SDL client in a connection string Using the ODBC Data Source You will not get anywhere faster

You can configure the server name in app.cconfig and use the connection string by using it. On deployment, you change the exe or user's .config file appropriately.

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...
