• WiX: Extracting Binary-string in Custom Action yields string like "???good data"

  - by leiflundgren

  I just found a weird behaviour when attempting to extract a string from the Binary-table in the MSI. I have a file containing "Hello world", the data I get is "???Hello world". (Literary question mark.) Is this as intended? Will it always be exactly 3 characters in the beginning? Regards Leif Sample code: [CustomAction] public static ActionResult CustomAction2(Session session) { View v = session.Database.OpenView("SELECT `Name`,`Data` FROM `Binary`"); v.Execute(); Record r = v.Fetch(); int datalen = r.GetDataSize("Data"); System.IO.Stream strm = r.GetStream("Data"); byte[] rawData = new byte[datalen]; int res = strm.Read(rawData, 0, datalen); strm.Close(); String s = System.Text.Encoding.ASCII.GetString(rawData); // s == "???Hello World" return ActionResult.Success; }

• Is it possible to broadcast audio to shoutcast / icecast / other server? from flash player?

  - by Jeffrey

  I am trying to create a flash client that can stream audio to an online radio server. Theoretically a user could enter the server info / login, and then connect and start sending data to the server which could then be broadcasted and listened to by other clients. I don't think this would be very hard, but am unsure about what data formats to use and what is the best server for the job. I'd like to be able to use one of the most popular radio servers like shoutCast. Any ideas? Thanks in advance.

• php - feof error

  - by TwixxyKit

  The file that I'm trying to read is a pgp-encrypted file. This is part of the process to decrypt it and I'm actually attempting to read the contents into a string so that I can then decrypt it . I'm not sure if that's the core problem here or not, but I'm getting an error: Warning: feof(): supplied argument is not a valid stream resource Here's the file code: if($handle = opendir($dir)) { while( false !== ($file = readdir($handle))) { if($file != "." && $file != "..") { $fhandle = fopen($file, "r"); $encrypted = ''; $filename = explode('.',$file); while(!feof($fhandle)) { $encrypted .= fread($fhandle, filesize($file)); } fclose($fhandle); $decrypted = $filename[0].'.txt'; shell_exec("echo $passphrase | $gpg --passphrase-fd 0 -o $decrypted -d $encrypted"); } } }

• How change Subversion's default binary mime-type?

  - by lamcro

  Subversion sets a binary file's svn:mime-type property to application/octet-stream by default. I need to change this default to some other mime-type. When I import for the first time this code, I would like Subversion to set mime-type to the one I choose. The reason is that my code base contains code in binary files (proprietary format), and I have the applications necessary to emulate diff and diff3 for these. But Subversion does not let me due to their default mime-type. Please note: There is no default extension (*.jar, *.py, etc) for these code files. Some files don't even have an extension. So configuring mime-type by file extension is not possible.

• How to retrieve email from GMail account using PHP?

  - by Tatu Ulmanen

  Hi, I'm trying to automatically retrieve some email from my GMail account for further parsing, but I can't get my head around on how to do that. I've searched the internets and it suggested that I use PHP's imap functions, like this: $server = '{imap.gmail.com:993/ssl}'; $connection = imap_open($server, '[email protected]', 'password'); But using that code, I get: Warning: imap_open() [function.imap-open]: Couldn't open stream {imap.gmail.com:993/ssl} Any idea what I am doing wrong? Any server setting that might be preventing me from making a connection to GMail (I'm using a shared service)? Is the address even right? Has anyone ever managed to do something like this? I've found tons of examples on how to send email via GMail, but very little of retrieving. Any help is much appreciated.

• Silverlight/Web Service Serializing Interface for use Client Side

  - by Steve Brouillard

  I have a Silverlight solution that references a third-party web service. This web service generates XML, which is then processed into objects for use in Silverlight binding. At one point we the processing of XML to objects was done client-side, but we ran into performance issues and decided to move this processing to the proxies in the hosting web project to improve performance (which it did). This is obviously a gross over-simplification, but should work. My basic project structure looks like this. Solution Solution.Web - Holds the web page that hosts Silverlight as well as proxies that access web services and processes as required and obviously the references to those web services). Solution.Infrastructure - Holds references to the proxy web services in the .Web project, all genned code from serialized objects from those proxies and code around those objects that need to be client-side. Solution.Book - The particular project that uses the objects in question after processed down into Infrastructure. I've defined the following Interface and Class in the Web project. They represent the type of objects that the XML from the original third-party gets transformed into and since this is the only project in the Silverlight app that is actually server-side, that was the place to define and use them. //Doesn't get much simpler than this. public interface INavigable { string Description { get; set; } } //Very simple class too public class IndexEntry : INavigable { public List<IndexCM> CMItems { get; set; } public string CPTCode { get; set; } public string DefinitionOfAbbreviations { get; set; } public string Description { get; set; } public string EtiologyCode { get; set; } public bool HighScore { get; set; } public IndexToTabularCommandArguments IndexToTabularCommandArgument { get; set; } public bool IsExpanded { get; set; } public string ManifestationCode { get; set; } public string MorphologyCode { get; set; } public List<TextItem> NonEssentialModifiersAndQualifyingText { get; set; } public string OtherItalics { get; set; } public IndexEntry Parent { get; set; } public int Score { get; set; } public string SeeAlsoReference { get; set; } public string SeeReference { get; set; } public List<IndexEntry> SubEntries { get; set; } public int Words { get; set; } } Again; both of these items are defined in the Web project. Notice that IndexEntry implments INavigable. When the code for IndexEntry is auto-genned in the Infrastructure project, the definition of the class does not include the implmentation of INavigable. After discovering this, I thought "no problem, I'll create another partial class file reiterating the implmentation". Unfortunately (I'm guessing because it isn't being serialized), that interface isn't recognized in the Infrastructure project, so I can't simply do that. Here's where it gets really weird. The BOOK project CAN see the INavigable interface. In fact I use it in Book, though Book has no reference to the Web Service in the Web project where the thing is define, though Infrastructure does. Just as a test, I linked to the INavigable source file from indside the Infrastructure project. That allowed me to reference it in that project and compile, but causes havoc in the Book project, because now there's a conflick between the one define in Infrastructure and the one defined in the Web project's web service. This is behavior I would expect. So, to try and sum up a bit. Web project has a web service that process data from a third-party service and has a class and interface defined in it. The class implements the interface. The Infrastructure project references the web service in the Web Project and the Book project references the Infrastructure project. The implmentation of the interface in the class does NOT serialize down, so the auto-genned code in INfrastructure does not show this relationship, breaking code further down-stream. The Book project, whihc is further down-stream CAN see the interface as defined in the Web Project, even though its only reference is through the Infrastructure project; whihc CAN'T see it. Am I simple missing something easy here? Can I apply an attribute to either the Interface definition or to the its implmentation in the class to ensure its visibility downstream? Anything else I can do here? I know this is a bit convoluted and anyone still with me here, thanks for your patience and any advice you might have. Cheers, Steve

• applet communication using post method

  - by mithun1538

  I have an applet that is communicating with a servlet. I am communicating with the servlet using POST method. My problem is how do I send parameters to the servlet. Using GET method, this is fairly simple ( I just append the parameters to the URL after a ?). But using POST method how do I send the parameters, so that in the servlet side, I can use the statement : message = req.getParameter("msg"); In the applet side, I establish POST method connection as follows : URL url = new URL(getCodeBase(), "servlet"); URLConnection con = url.openConnection(); con.setDoInput(true); con.setDoOutput(true); con.setUseCaches(false); con.setRequestProperty("Content-Type","application/octet-stream");

• Using Api to submit userdata to external party

  I have to submit subscription data to another website. I have got documentation on how to use this API however i'm not 100% sure of how to set this up. I do have all the information needed, like username / passwords etc. This is the API documentation: https://www.apiemail.net/api/documentation/?SID=4 How would my request / post / whatever look like in C# .net (vs 2008) when i'm trying to acces this API?

• Merge two bytes in java/android

  - by Shane

  Hi, I have a frame of 22 bytes. The frame is the input stream from an accelerometer via bluetooth. The acceleromter readings are a 16 bit number split over two bytes. When i try to merge the bytes with buffer[1] + buffer[2], rather than adding the bytes, it just puts the results side by side. so 1+2 = 12. Could someone tell me how to combine these two bytes to obtain the original number. (btw the bytes are sent little endian) Thanks

• How do you update the server name in source indexed symbol file?

  - by Keith Hill

  With the Debugging Tools for Windows you can run SSIndex.cmd against your symbol files and it will embed the command to retrieve each source code file from the TF server. We have a bunch of indexed files and recently our IT migrated our TFS 2008 installation to TFS 2010 and in the process changed the server name. Question is, how can I update all these symbol files to point to the new server? I thought SSindex used an alternate data stream named 'srcsrv' but SysInternals' streams.exe shows nothing on these symbol files even though srctool.exe shows the data.

• Lackadaisical One-to-One between Char and Byte Streams

  - by Vaibhav Bajpai

  I expected to have a one-to-one correspondence between the character streams and byte streams in terms of how the classes are organized in their hierarchy. FilterReader and FilterWriter (character streams) correspond back to FilterInputStream and FilterOutputStream (byte stream) classes. However I noticed few changes as - BufferedInputStream extends FilterInputStream, but BufferedReader does NOT extend FilterReader. BufferedOutputStream and PrintStream both extend FilterOutputStream, but BufferedWriter and PrintWriter does NOT extend FilterWriter. FilterInputStream and FilterOutputStream are not abstract classes, but FilterReader and FilterWriter are. I am not sure if I am being too paranoid to point out such differences, but was just curious to know if there was design reasoning behind such decision.

• Processing CSV File

  - by nettguy

  I am using Sebastien LorionReference CSV reader to process my CSV file in C# 3.0. Say example id|name|dob (Header) 1|sss|19700101 (data) 2|xx|19700201 (data) My Business Object is class Employee { public string ID {get;set;} public string Name {get;set;} public string Dob {get;set;} } I read the CSV stream and stored it in List<string[]> List<string[]> col = new List<string[]>(); using (CsvReader csv = new CsvReader (new StreamReader("D:\\sample.txt"), true, '|')) { col = csv.ToList(); } How to iterate over the list to get each Employee like foreach (var q in col) { foreach (var r in q) { Employee emp=new Employee(); emp.ID =r[0]; emp.Name=r[1]; emp.Dob=r[2]; } } If i call r[0],r[1],r[2] i am getting "index out of range exception".How the process the list to avoid the error?

• Cucumber - How configure it to use "--format pretty" as default?

  - by Gabriel L. Oliveira

  I'm starting learning rails, and having some troubles on configure cucumber to run my bdd tests. What I want is run cucumber features and this translate to cucumber features --format pretty I tried to do this editing the config/cucumber.yml file (on a rails project). Edited the line: default: <%= std_opts % features resulting on: default: <%= std_opts % --format pretty features But it make some erros happen: Using the default profile... All but one formatter must use --out, only one can print to each stream (or STDOUT) (RuntimeError) What I can do to make this option "--format pretty" default? Also, is there any other good option to put as default to make result more clear? Thank you.

• What is the largest file size we can transfer through air application?

  - by Naveen kumar

  Hi all, I'm trying to transfer large file(1Gb+) using UDP(in packets) through air application. I'm transfering byteArray by taking chunks of packets from FileStream. But its giving 'Error #1000: The system is out of memory' at sender side after certain number of packets sent and by this time the downloaded file size at server side is 256 MB. I tried with other files but after downloading 256MB, sender is giving the same error. Is it because of the file stream size? How can I solve this problem so that I can transfer files of GB size.

• C++ Sentinel/Count Controlled Loop beginning programming

  - by Bryan Hendricks

  Hello all this is my first post. I'm working on a homework assignment with the following parameters. Piecework Workers are paid by the piece. Often worker who produce a greater quantity of output are paid at a higher rate. 1 - 199 pieces completed $0.50 each 200 - 399 $0.55 each (for all pieces) 400 - 599 $0.60 each 600 or more $0.65 each Input: For each worker, input the name and number of pieces completed. Name Pieces Johnny Begood 265 Sally Great 650 Sam Klutz 177 Pete Precise 400 Fannie Fantastic 399 Morrie Mellow 200 Output: Print an appropriate title and column headings. There should be one detail line for each worker, which shows the name, number of pieces, and the amount earned. Compute and print totals of the number of pieces and the dollar amount earned. Processing: For each person, compute the pay earned by multiplying the number of pieces by the appropriate price. Accumulate the total number of pieces and the total dollar amount paid. Sample Program Output: Piecework Weekly Report Name Pieces Pay Johnny Begood 265 145.75 Sally Great 650 422.50 Sam Klutz 177 88.5 Pete Precise 400 240.00 Fannie Fantastic 399 219.45 Morrie Mellow 200 110.00 Totals 2091 1226.20 You are required to code, compile, link, and run a sentinel-controlled loop program that transforms the input to the output specifications as shown in the above attachment. The input items should be entered into a text file named piecework1.dat and the ouput file stored in piecework1.out . The program filename is piecework1.cpp. Copies of these three files should be e-mailed to me in their original form. Read the name using a single variable as opposed to two different variables. To accomplish this, you must use the getline(stream, variable) function as discussed in class, except that you will replace the cin with your textfile stream variable name. Do not forget to code the compiler directive #include < string at the top of your program to acknowledge the utilization of the string variable, name . Your nested if-else statement, accumulators, count-controlled loop, should be properly designed to process the data correctly. The code below will run, but does not produce any output. I think it needs something around line 57 like a count control to stop the loop. something like (and this is just an example....which is why it is not in the code.) count = 1; while (count <=4) Can someone review the code and tell me what kind of count I need to introduce, and if there are any other changes that need to be made. Thanks. [code] //COS 502-90 //November 2, 2012 //This program uses a sentinel-controlled loop that transforms input to output. #include <iostream> #include <fstream> #include <iomanip> //output formatting #include <string> //string variables using namespace std; int main() { double pieces; //number of pieces made double rate; //amout paid per amount produced double pay; //amount earned string name; //name of worker ifstream inFile; ofstream outFile; //***********input statements**************************** inFile.open("Piecework1.txt"); //opens the input text file outFile.open("piecework1.out"); //opens the output text file outFile << setprecision(2) << showpoint; outFile << name << setw(6) << "Pieces" << setw(12) << "Pay" << endl; outFile << "_____" << setw(6) << "_____" << setw(12) << "_____" << endl; getline(inFile, name, '*'); //priming read inFile >> pieces >> pay >> rate; // ,, while (name != "End of File") //while condition test { //begining of loop pay = pieces * rate; getline(inFile, name, '*'); //get next name inFile >> pieces; //get next pieces } //end of loop inFile.close(); outFile.close(); return 0; }[/code]
