  • Reading ini file in C#

    - by pm_2
    I am trying to read an ini file that has the following format: SETTING=VALUE SETTING2=VALUE2 I currently have the following code: string cache = sr.ReadToEnd(); string[] splitCache = cache.Split(new string[] {"\n", "\r\n"}, StringSplitOptions.RemoveEmptyEntries); Which gives me a list of settings, however, what I would like to do is read this into a dictionary. My question is, is there a way to do this without iterating through the entire array and manually populating the dictionary?

  • Accessing Identity.AuthenticationType

    - by Tewr
    While implementing a custom authentication type in a wcf service, I'm trying to read the property IIdentity.AuthenticationType using the call Thread.CurrentPrincipal.Identity.AuthenticationType. Unless the account running the service is local administrator, UnauthorizedAccessException is thrown when accessing this property, much like described in this support thread. I can however reset the Thread.CurrentPrincipalobject without hassle, thus altering the Authentication Type - But read it, I cannot. Is running as an administrator the only way here or is there some trick to let the user running the service "just" access this property?

  • Static variables in C and C++

    - by Naveen
    Is there any difference between a variable declared as static outside any function between C and C++. I read that static means file scope and the variables will not be accessible outside the file. I also read that in C, global variables are static . So does that mean that global variables in C can not be accessed in another file?

  • Erlang Types Specifications

    - by Chang
    I recently read the source code of couch-db, I find this type definition which i don't understand: -type branch() :: {Key::term(), Value::term(), Tree::term()}. -type path() :: {Start::pos_integer(), branch()}. -type tree() :: [branch()]. I did read Erlang doc, But what is the meaning of Start, Key, Value and Tree? From what i understand, they are Erlang variables! I didn't find any information about this in Erlang doc.

  • Encrypt file using M2Crypto

    - by Bear
    It is known that I can read the whole file content in memory and encrypt it using the following code. contents = fin.read() cipher = M2Crypto.EVP.Cipher(alg="aes_128_cbc", key = aes_key, iv = aes_iv, op = 1) encryptedContents = cipher.update(contents) encryptedContents += cipher.final() But what if the file size is large, is there a way for me to pass the input stream to M2Crypto instead of reading the whole file first?

  • How to change file contents in PHP ?

    - by Misha Moroshko
    I save in a file some info about users (like number of times user passed the login page, last visited time, and so on). I want to read this info from the file, and update it (add 1 to the counter, and change the last visited time). My question is: can I do it without opening the file twice ? I open the first time to read the contents, and then open it again to overwrite the contents with the updated ones. Thanks !

  • BlackBerry OS 7.1 secured TLS connection is closed after very short time

    - by MrVincenzo
    To make a long story short: Same client-server configuration, same network topology, same device (Bold 9900) - works perfectly well on OS 7.0 but doesn't work as expected on OS 7.1 and the secured tls connection is being closed by the server after a very short time. My application opens a secured tls connection to a server. The connection is kept alive by a application layer keep-alive mechanism and remains open until the client closes it. Attached is a simplified version of the actual code that opens connection and reads from the socket. The code works perfectly on OS 5.0-7.0 but doesn't work as expected on OS 7.1. When running on OS 7.1, the blocking read() returns with -1 (end of the stream has been reached) after very short time (10-45 seconds). For OS 5.0-7.0 the call to read() remains blocking until next data arrives and the connection is never closed by the server. Connection connection = Connector.open(connectionString); connInputStream = connection.openInputStream(); while (true) { try { retVal = connInputStream.read(); if (-1 == retVal) { break; // end of stream has been reached } } catch (Exception e ) { // do error handling } // data read from stream is handled here } UPDATE 1: Apparently, the problem appears only when I use secured tls connection (either using mobile network or WiFi) on OS 7.1. Everything works as expected when opening a non secured connection on OS 7.1. For tls on mobile networks I use the following connection string: connectionString = "tls://someipaddress:443;deviceside=false;ConnectionType=mds-public;EndToEndDesired"; For tls on Wifi I use the following connection string: connectionString = "tls://someipaddress:443;deviceside=true;interface=wifi;EndToEndRequired" UPDATE 2: The connection is never idle. I am constantly receiving and sending data on it. The issue appears both when using mobile connection and WiFi. The issue appears both on real OS 7.1 devices and simulators. I am starting to suspect that it is somehow related either to the connection string I am using or to the tls handshake. UPDATE 3: According to Wireshark's captures that I made with the OS 7.1 simulator, the secured tls connection is being closed by the server (client receives FIN). For the moment I don't have the server's private key therefore I unable to debug the tls handshake.

  • How to allocate memory in another process for windows mobile

    - by Serafeim
    I'd like to read the contents of another process listview control in windows mobile. To do this, I need a pointer to some free memory to that process in order to put the values there (and then read them from my process). This can be done in normal Windows or Win32 with the VirtualAllocEx function. However, this function is not supported in windows mobile ! Can you recommend me a way to allocate that memory?

  • ProgressBar isn't updating

    - by Nuru Salihu
    I have a progressbar that that is show progress returned by the backgroundworker do_dowork event like below . if (ftpSourceFilePath.Scheme == Uri.UriSchemeFtp) { FtpWebRequest objRequest = (FtpWebRequest)FtpWebRequest.Create(ftpSourceFilePath); NetworkCredential objCredential = new NetworkCredential(userName, password); objRequest.Credentials = objCredential; objRequest.Method = WebRequestMethods.Ftp.DownloadFile; FtpWebResponse objResponse = (FtpWebResponse)objRequest.GetResponse(); StreamReader objReader = new StreamReader(objResponse.GetResponseStream()); int len = 0; int iProgressPercentage = 0; FileStream objFS = new FileStream((cd+"\\VolareUpdate.rar"), FileMode.Create, FileAccess.Write, FileShare.Read); while ((len = objReader.BaseStream.Read(buffer, 0, buffer.Length)) > 0) { objFS.Write(buffer, 0, len); iRunningByteTotal += len; double dIndex = (double)(iRunningByteTotal); double dTotal = (double)buffer.Length; double dProgressPercentage = (dIndex / dTotal); iProgressPercentage = (int)(dProgressPercentage); if (iProgressPercentage > 100) { iProgressPercentage = 100; } bw.ReportProgress(iProgressPercentage); } } However, my progressbar does not update. While searching , i was told the UI thread is being blocked and then i thought may be passing the progress outside the loop will do the trick. then i change to this if (ftpSourceFilePath.Scheme == Uri.UriSchemeFtp) { FtpWebRequest objRequest = (FtpWebRequest)FtpWebRequest.Create(ftpSourceFilePath); NetworkCredential objCredential = new NetworkCredential(userName, password); objRequest.Credentials = objCredential; objRequest.Method = WebRequestMethods.Ftp.DownloadFile; FtpWebResponse objResponse = (FtpWebResponse)objRequest.GetResponse(); StreamReader objReader = new StreamReader(objResponse.GetResponseStream()); int len = 0; int iProgressPercentage = 0; FileStream objFS = new FileStream((cd+"\\VolareUpdate.rar"), FileMode.Create, FileAccess.Write, FileShare.Read); while ((len = objReader.BaseStream.Read(buffer, 0, buffer.Length)) > 0) { objFS.Write(buffer, 0, len); iRunningByteTotal += len; double dIndex = (double)(iRunningByteTotal); double dTotal = (double)buffer.Length; double dProgressPercentage = (dIndex / dTotal); iProgressPercentage = (int)(dProgressPercentage); if (iProgressPercentage > 100) { iProgressPercentage = 100; } // System.Threading.Thread.Sleep(2000); iProgressPercentage++; // SetText("F", true); } bw.ReportProgress(iProgressPercentage); progressBar.Refresh(); } However still didn't help. When i put break point in my workerprogresschanged event, it show the progressbar.value however does not update. I tried progressbar.update(0, i also tried sleeping the thread for a while in the loop still didn't help. Please any suggestion/help would be appreciated .

  • How do I use File.new to find a file from Rails?

    - by Angela
    I am trying to read a file that has been saved on the /system folder using Paperclip, for example. But when I use that .url method from Paperclip to read that file using File.new, I get that the file isn't found. The directory is correct, but I still can't access it. What is the right way to find a file for File.new for example? I tried to point to other files, as well, and to no avail.

  • hibernate annotation- extending base class - values are not being set - strange error

    - by gt_ebuddy
    I was following Hibernate: Use a Base Class to Map Common Fields and openjpa inheritance tutorial to put common columns like ID, lastModifiedDate etc in base table. My annotated mappings are as follow : BaseTable : @MappedSuperclass public abstract class BaseTable { @Id @GeneratedValue @Column(name = "id") private int id; @Column(name = "lastmodifieddate") private Date lastModifiedDate; ... Person table - @Entity @Table(name = "Person ") public class Person extends BaseTable implements Serializable{ ... Create statement generated : create table Person (id integer not null auto_increment, lastmodifieddate datetime, name varchar(255), primary key (id)) ; After I save a Person object to db, Person p = new Person(); p.setName("Test"); p.setLastModifiedDate(new Date()); .. getSession().save(p); I am setting the date field but, it is saving the record with generated ID and LastModifiedDate = null, and Name="Test". Insert Statement : insert into Person (lastmodifieddate, name) values (?, ?) binding parameter [1] as [TIMESTAMP] - <null> binding parameter [2] as [VARCHAR] - Test Read by ID query : When I do hibernate query (get By ID) as below, It reads person by given ID. Criteria c = getSession().createCriteria(Person.class); c.add(Restrictions.eq("id", id)); Person person= c.list().get(0); //person has generated ID, LastModifiedDate is null select query select person0_.id as id8_, person0_.lastmodifieddate as lastmodi8_, person0_.name as person8_ from Person person0_ - Found [1] as column [id8_] - Found [null] as column [lastmodi8_] - Found [Test] as column [person8_] ReadAll query : //read all Query query = getSession().createQuery("from " + Person.class.getName()); List allPersons=query.list(); Corresponding SQL for read all select query select person0_.id as id8_, person0_.lastmodifieddate as lastmodi8_, person0_.name as person8_ from Person person0_ - Found [1] as column [id8_] - Found [null] as column [lastmodi8_] - Found [Test] as column [person8_] - Found [2] as column [id8_] - Found [null] as column [lastmodi8_] - Found [Test2] as column [person8_] But when I print out the list in console, its being more weird. it is selecting List of Person object with ID fields = all 0 (why all 0 ?) LastModifiedDate = null Name fields have valid values I don't know whats wrong here. Could you please look at it? FYI, My Hibernate-core version : 4.1.2, MySQL Connector version : 5.1.9 . In summary, There are two issues here Why I am getting All ID Fields =0 when using read all? Why the LastModifiedDate is not being inserted?

  • How to use length indicator in a C++ program

    - by cj
    I want to make a program in C++ that reads a file where each field will have a number before it that indicates how long it is. The problem is I read every record in object of a class; how do I make the attributes of the class dynamic? For example if the field is "john" it will read it in a 4 char array. I don't want to make an array of 1000 elements as minimum memory usage is very important.
