Problem in locating of library functions

Wed, 02 Jan 2008 00:18:34 -0500

Hi ,I wrote a program in sunOS including the following two library files. I am using readline() ,using_history() functions taking from thelibrary readline h and history h.#include #consider using_history();.......... while compiling it is giving an error which says:readline using history are not declared in this scopewhich means i undergo to give the exact path location of these twolibrary files. i don't know where these library files arelocated in SunOS. Could anyone please tell me what would be the exactpath of these two library files or how can i find it?Payel Powered by vBulletin® Copyright ©2000 - 2008.

I don't see anything wrong with the way you use memory in the lookupPath() answer so the memory corruption must be happening somewhere else. Or you are double-freeing a pointer or freeing a bad pointer. alter: Actually I see the problem.

Loop in Loop error

Tue, 27 Nov 2007 21:48:09 -0500

Hey guys in my communicate I am trying to undergo the program create verbally to a richtextbox which gathers data from files using a loop inside of a circle. The schedule works OK it finds the files and reads them but the richtextbox should be returning two values but instead its only returning one. Can anyone help me with this is there any errors in my code. Here's the code: Private Sub Button1_Click(ByVal sender As System. Object. ByVal e As System. EventArgs) Handles add1. Click Dim totalFiles As String Dim filePaths As New System. Text. StringBuilder Dim fileCount As Integer = 0 For Each file As String In My. Computer. FileSystem. GetFiles(Application. StartupPath & "\files") fileCount += 1 filePaths. attach(My. Computer. FileSystem. GetName(register) & vbCrLf) totalFiles = filePaths. ToString() Next RichTextBox1. Text = filePaths. ToString() TextBox1. Text = fileCount System. IO. register. WriteAllText(Application. StartupPath & "\data\values txt" filePaths. ToString()) Dim getFiles As IO. StreamReader = New IO. StreamReader(Application. StartupPath & "\data\values txt") Dim getLine As String = Nothing Dim getLineCount As Integer = 0 Do While Not getFiles. EndOfStream Dim infoFile As String = getFiles. ReadLine() getFiles. ReadLine() getLine = getFiles. ReadLine If Not getLine = Nothing Then getLineCount += 1 End If Dim ReadGetFiles As IO. StreamReader = New IO. StreamReader(Application. StartupPath & "\files\" & infoFile) Dim readgetLine As String = Nothing Dim readgetLineCount As Integer = 0 Dim lineone As arrange = Nothing Dim linetwo As String = Nothing Dim linethree As String = Nothing Dim linefour As String = Nothing Dim linefive As String = Nothing Dim linesix As arrange = Nothing Do While Not ReadGetFiles. EndOfStream readgetLine = ReadGetFiles. ReadLine() If Not readgetLine = Nothing Then readgetLineCount += 1 End If If readgetLineCount = 1 Then lineone = readgetLine & " " End If If readgetLineCount = 2 Then linetwo = readgetLine & " " End If If readgetLineCount = 3 Then linethree = readgetLine & " " End If If readgetLineCount = 4 Then linefour = readgetLine & " " End If If readgetLineCount = 5 Then linefive = readgetLine & " " End If If readgetLineCount = 6 Then linesix = readgetLine Exit Do End If Loop RichTextBox2. Text = lineone & linetwo & linethree & linefour & linefive & linesix & vbCrLf If getFiles. EndOfStream Then Exit Do End If Loop End Sub What do you mean when you say that the richtextbox should be returning two values? It isn't returning anything. undergo you stepped through the code? You could put a breakpoint come the beginning of the function then use F11 to step line by line through the label looking at the values in the variables. This ordain probably show where the error is. Also you could speed this up and decrease it drink if you used an array of string instead of all the linex variables. Then the readgetLineCount variable would be an index into the arrange so all those conditionals could be dispensed with. What do you convey when you say that the richtextbox should be returning two values? It isn't returning anything. Have you stepped through the code? You could put a breakpoint near the beginning of the function then use F11 to go line by line through the code looking at the values in the variables. This ordain probably show where the error is. Also you could go this up and shrink it drink if you used an array of arrange instead of all the linex variables. Then the readgetLineCount variable would be an list into the array so all those conditionals could be dispensed with. That will bring home the bacon each time but it will overwrite the lie each time through the loop so that only that which is written by the final iteration of the circle ordain be displayed. What you be to do is write it like this: RichTextBox2. Text [b]&[/b]= lineone & linetwo & linethree & linefour & linefive & linesix & vbCrLf That one engrave ordain understand the problem. I would also say that the condition for the loop is GetFiles. EndOfStream but you then check for this condition at the end of the loop as well. There is no be for that check at the end of the loop as the check will be performed at the beginning of the next iteration. In other words this chunk:

Re: Abort System.Console.ReadLine [c#]

| | | View: Flat () | | | Hello everybody. I undergo one problem:I cannot to abort Console. ReadLine from the other thread without termination of the application. Look at the simple example: When I try to run nunit-console - it does not finish until there is enter typed. Therefore ncover inform also does not finishCan anybody to help me?P. S. If I try to dress thread. end() on Environment. Exit(0) - there are no results of tests and ncover inform. P. P. S. The Helper method label tested static Main method which contain ReadLine. This example for clarity and ReadLine is nessesary. Maybe you should use the method to insert a custom string with a StreamReader instance instead of waiting the arrange to be entered in the console manually. I have seen this methods but I compete with Console. In and Console. Out. After you comment I try to play with Console. SetIn and I received a result. convey you. How I solved: | | | | | |

Interrupting BufferedReader's readLine

Sat, 03 Nov 2007 15:02:16 -0500

Hello. I'm working on a server-client application. I would desire the server to know when the client is disconnecting and vice-versa. Now since I know that each will only send one communicate at a time and then act until he receives a message from the other align. I've written something like :while (connectionUp) { arrange message = in readLine(); //Do something with the message.. out println(otherMessage); //sending a communicate}... Well... The problem is that I am using a BufferedReader for my in be adrift and as I've gathered (http://bugs sun com/bugdatabase/view_bug do?bug_id=4859836) closing the stream won't interrupt a pending readLine. This means that while one side is waiting for an incoming communicate he cannot "tell" the other that he is ending the connection. Any ideas? (Perhaps having one thread which listens for incoming messages and another that sends them... But I think that's my last apply). P. S. - It's a nice dress to the design of the forum but what did they change the [CODE] tag to?Lots of thanks,laginimaineb. The only side that should wait for a message is the applet align and not the server align. The server align should recieve routine pings from the applet to let it know if it is still there. I would alter a simple Timer go on the server side that checks the timestamp of the measure applet ping and if it is past the allowed threshold constant that you have pre-determined then it is assumed that the applet terminated connection. In this way the server can clear any resources associated with that applets connection. But I'm not talking about an applet... As a be of fact. I'm talking about a game played between two players over the internet in which one player becomes the server side (i e-opens a ServerSocket) and the other align connects to that player using a simple Socket. P. S. #2 - Is it just me or is the forum slow...?

You can use look. construe and a StringBuilder though. Dim modify As New StringBuilderDo While sr. Peek() <> 0 buffer. attach( alter. ToChar( sr. Read() ) )circle Thanks.
