ioexception

I am new to programming and I have a question. If I have two functions, one creates a text file and writes into it, while the other opens the same text file and reads from it. The error I get is: System.IO.IOException: 'The process cannot access the file '@.txt' because it is being used by another process.' I have tried setting seperate timers to each of the functions but it still does not work. I think the best way would be that the function two does not start until function one ends. Can you help me achieve this? Thank you very much! Mike Source code: public Form1() { InitializeComponent();

I hava small windows app where user enter code and on button click event code is compiled at runtime. When i click button 1st time it works fine but if click same button more than once it gives error "The process cannot access the Exmaple.pdb file because it is being used by another process." .

I am doing an Android application where I need 2 devices or more to be able to connect to one device via Bluetooth. The code to connect two devices together in a peer-to-peer form works, but when I try to connect another I get an IOException saying "Connection refused" because the Socket is closed and as such, is unable to complete pairing. The error is shown below. Socket closed. Unable to complete pairing. java.io.IOException: Connection refused at android.bluetooth.BluetoothSocket.connectNative(Native Method) at android.bluetooth.BluetoothSocket.connect(BluetoothSocket.java:216) at com

I am doing some exception handling for code which is writing to the StandardInput stream of a Process object. The Process is kind of like the unix head command; it reads only part of it's input stream. When the process dies, the writing thread fails with: IOException The pipe has been ended. (Exception from HRESULT: 0x8007006D) I would like to catch this exception and let it fail gracefully, since this is expected behavior. However, it's not obvious to me how this can robustly be distinguished from other IOExceptions. I could use message, but it's my understanding that these are localized and

I've not been able to resolve the following exception in the code below. What is the problem with the way I use BufferedReader? I'm using BufferedReader inside the main method OUTPUT :- ParseFileName.java:56: unreported exception java.io.FileNotFoundException; must be caught or declared to be thrown BufferedReader buffread = new BufferedReader (new FileReader("file.txt")); // ParseFileName is used to get the file name from a file path // For eg: get - crc.v from "$ROOT/rtl/..path/crc.v" import java.util.regex.Pattern; import java.io.*; public class ParseFileName { //Split along /'s , and

I am trying to read a text file that is already saved in my directory and print it on the screen as a TextView. This is the code that I have so far. However, when I run the application, it creates a toast which says "Error Reading File". What am I doing wrong here? public class sub extends Activity { private TextView text; protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.text); //text = (TextView) findViewById(R.id.summtext); //File file = new File("inputNews.txt"); //StringBuilder text = new StringBuilder(); try { InputStream in

I want to create and open a file but only if it doesnt exist. I dont want to use a File.Exists because a thread by switch after it creating a file with the same name. How do i check if the exception System.IO.IOException was caused by the file existing? I prefer not to parse the error msg (even tho it can be as simple as .indexOf("exist")) How should i do this? You should avoid ever making logic decisions based on the contents of the Exception.Message property. That is defined to be a human-readable message, not something for a program to read. Such messages are subject to change without
