  • HTTP POST to Imageshack

    - by Brandon Schlenker
    I am currently uploading images to my server via HTTP POST. Everything works fine using the code below. NSString *UDID = md5([UIDevice currentDevice].uniqueIdentifier); NSString *filename = [NSString stringWithFormat:@"%@-%@", UDID, [NSDate date]]; NSString *urlString = @"http://taptation.com/stationary_data/index.php"; request= [[[NSMutableURLRequest alloc] init] autorelease]; [request setURL:[NSURL URLWithString:urlString]]; [request setHTTPMethod:@"POST"]; NSString *boundary = @"---------------------------14737809831466499882746641449"; NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@",boundary]; [request addValue:contentType forHTTPHeaderField: @"Content-Type"]; NSMutableData *postbody = [NSMutableData data]; [postbody appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]]; [postbody appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"userfile\"; filename=\"%@.jpg\"\r\n", filename] dataUsingEncoding:NSUTF8StringEncoding]]; [postbody appendData:[[NSString stringWithString:@"Content-Type: application/octet-stream\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]]; [postbody appendData:[NSData dataWithData:imageData]]; [postbody appendData:[[NSString stringWithFormat:@"\r\n--%@--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]]; [request setHTTPBody:postbody]; NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil]; returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding]; NSLog(returnString); However, when I try to convert this to work with Image Shacks XML API, it doesn't return anything. The directions from ImageShack are below. Send the following variables via POST to imageshack. us /index.php fileupload; (the image) xml = "yes"; (specifies the return of XML) cookie; (registration code, optional) Does anyone know where I should go from here?

  • PGP Encrypt from C# using GnuPG

    - by Kishore
    Hello All, I'm trying to encrypt a incoming document in C#, and I'm using GnuPG with input redirection. I need to use -se(sign and encrypt) in a single step, which requires entering passphrase. But for some reason, input redirection is not working. Appreciate your help. Control is going to else block. I'm not sure if there is deadlock or child process(gpg.exe) waiting for the input. pgpproc = new Process(); pgpproc.StartInfo.FileName = exeFilePath; pgpproc.StartInfo.RedirectStandardOutput = false; pgpproc.StartInfo.RedirectStandardInput = true; pgpproc.StartInfo.UseShellExecute = false; pgpproc.StartInfo.Arguments = "-a -o C:\PGPStaging\output.pgp -se -r recipientID C:\PGPStaging\input.txt"; pgpproc.StartInfo.CreateNoWindow = true; pgpproc.Start(); StreamWriter myStreamWriter = pgpproc.StandardInput; myStreamWriter.Write("*****"); myStreamWriter.Close(); if (pgpproc.WaitForExit(waittime)) { //success } else { //failure pgpproc.Kill(); pgpproc.WaitForExit(); } `

Here is what I want to happen: Set arduino up with an LED as a digital out Set potentiometer to analog 0 Set PyQt timer up to update potentiometer position in application Set a threshold in PyQt to turn LED on (Analog in has 1024bit resolution, so say 800 as the threshold) I am using this firmata library : Link Here is the code that I am having trouble with: import sys from PyQt4 import QtCore, QtGui from firmata import * # Arduino setup self.a = Arduino('COM3') self.a.pin_mode(13, firmata.OUTPUT) # Create timer self.appTimer = QtCore.QTimer(self) self.appTimer.start(100) self.appTimer.event(self.updateAppTimer()) def updateAppTimer(self): self.analogPosition = self.a.analog_read(self, 0) self.ui.lblPositionValue.setNum() I am getting the error message: Traceback (most recent call last): File "D:\Programming\Eclipse\IO Demo\src\control.py", line 138, in myapp = MainWindow() File "D:\Programming\Eclipse\IO Demo\src\control.py", line 56, in init self.appTimer.event(self.updateAppTimer()) File "D:\Programming\Eclipse\IO Demo\src\control.py", line 60, in updateAppTimer self.analogPosition = self.a.analog_read(self, 0) TypeError: analog_read() takes exactly 2 arguments (3 given) If I take 'self' out I get the same error message but that only 1 argument is given What is python doing implicitly that I am not aware of?

  • Reading audio with Extended Audio File Services (ExtAudioFileRead)

    - by Paperflyer
    I am working on understanding Core Audio, or rather: Extended Audio File Services Here, I want to use ExtAudioFileRead() to read some audio data from a file. This works fine as long as I use one single huge buffer to store my audio data (that is, one AudioBuffer). As soon as I use more than one AudioBuffer, ExtAudioFileRead() returns the error code -50 ("error in parameter list"). As far as I can figure out, this means that one of the arguments of ExtAudioFileRead() is wrong. Probably the audioBufferList. I can not use one huge buffer because then, dataByteSize would overflow its UInt32-integer range with huge files. Here is the code to create the audioBufferList: AudioBufferList *audioBufferList; audioBufferList = malloc(sizeof(AudioBufferList) + (numBuffers-1)*sizeof(AudioBuffer)); audioBufferList->mNumberBuffers = numBuffers; for (int bufferIdx = 0; bufferIdx<numBuffers; bufferIdx++ ) { audioBufferList->mBuffers[bufferIdx].mNumberChannels = numChannels; audioBufferList->mBuffers[bufferIdx].mDataByteSize = dataByteSize; audioBufferList->mBuffers[bufferIdx].mData = malloc(dataByteSize); } UInt32 numFrames = fileLengthInFrames; error = ExtAudioFileRead(extAudioFileRef, &numFrames, audioBufferList); Do you know what I am doing wrong here?

  • Friend Assemblies in C#

    - by Tim Long
    I'm trying to create some 'friend assemblies' using the [InternalsVisibleTo()] attribute, but I can't seem to get it working. I've followed Microsoft's instructions for creating signed friend assemblies and I can't see where I'm going wrong. So I'll detail my steps here and hopefully someone can spot my deliberate mistake...? Create a strong name key and extract the public key, thus: sn -k StrongNameKey sn -p public.pk sn -tp public.pk Add the strong name key to each project and enable signing. Create a project called Internals and a class with an internal property: namespace Internals { internal class ClassWithInternals { internal string Message { get; set; } public ClassWithInternals(string m) { Message = m; } } } Create another project called TestInternalsVisibleTo: namespace TestInternalsVisibleTo { static class Program { /// <summary> /// The main entry point for the application. /// </summary> [STAThread] static void Main() { var c = new Internals.ClassWithInternals("Test"); Console.WriteLine(c.Message); } } } Edit the AssemblyInfo.cs file for the Internals project, and add teh necessary attribute: [assembly: AssemblyTitle("AssemblyWithInternals")] [assembly: AssemblyDescription("")] [assembly: AssemblyConfiguration("")] [assembly: AssemblyCompany("Microsoft")] [assembly: AssemblyProduct("Internals")] [assembly: AssemblyCopyright("Copyright © Microsoft 2010")] [assembly: AssemblyTrademark("")] [assembly: AssemblyCulture("")] [assembly: ComVisible(false)] [assembly: Guid("41c590dc-f555-48bc-8a94-10c0e7adfd9b")] [assembly: AssemblyVersion("1.0.0.0")] [assembly: AssemblyFileVersion("1.0.0.0")] [assembly: InternalsVisibleTo("TestInternalsVisibleTo PublicKey=002400000480000094000000060200000024000052534131000400000100010087953126637ab27cb375fa917c35b23502c2994bb860cc2582d39912b73740d6b56912c169e4a702bedb471a859a33acbc8b79e1f103667e5075ad17dffda58988ceaf764613bd56fc8f909f43a1b177172bc4143c96cf987274873626abb650550977dcad1bb9bfa255056bb8d0a2ec5d35d6f8cb0a6065ec0639550c2334b9")] And finally... build! I get the following errors: error CS0122: 'Internals.ClassWithInternals' is inaccessible due to its protection level error CS1729: 'Internals.ClassWithInternals' does not contain a constructor that takes 1 arguments error CS1061: 'Internals.ClassWithInternals' does not contain a definition for 'Message' and no extension method 'Message' accepting a first argument of type 'Internals.ClassWithInternals' could be found (are you missing a using directive or an assembly reference?) Basically, it's as if I had not used the InternalsVisibleTo attrbute. Now, I'm not going to fall into the trap of blaming the tools, so what's up here? Anyone?

  • Create Zip File In Windows and Extract Zip File In Linux

    - by Yan Cheng CHEOK
    I had created a zip file (together with directory) under Windows as follow : package sandbox; import java.io.File; import java.io.FileInputStream; import java.io.FileOutputStream; import java.io.IOException; import java.util.zip.ZipEntry; import java.util.zip.ZipOutputStream; /** * * @author yan-cheng.cheok */ public class Main { /** * @param args the command line arguments */ public static void main(String[] args) { // These are the files to include in the ZIP file String[] filenames = new String[]{"MyDirectory" + File.separator + "MyFile.txt"}; // Create a buffer for reading the files byte[] buf = new byte[1024]; try { // Create the ZIP file String outFilename = "outfile.zip"; ZipOutputStream out = new ZipOutputStream(new FileOutputStream(outFilename)); // Compress the files for (int i=0; i<filenames.length; i++) { FileInputStream in = new FileInputStream(filenames[i]); // Add ZIP entry to output stream. out.putNextEntry(new ZipEntry(filenames[i])); // Transfer bytes from the file to the ZIP file int len; while ((len = in.read(buf)) > 0) { out.write(buf, 0, len); } // Complete the entry out.closeEntry(); in.close(); } // Complete the ZIP file out.close(); } catch (IOException e) { e.printStackTrace(); } } } The newly created zip file can be extracted without problem under Windows, by using http://www.exampledepot.com/egs/java.util.zip/GetZip.html However, I realize if I extract the newly created zip file under Linux, using http://www.exampledepot.com/egs/java.util.zip/GetZip.html, I will get a file named "MyDirectory\MyFile.txt" instead of MyFile.txt being placed under folder MyDirectory. I try to solve the problem by changing the zip file creation code to String[] filenames = new String[]{"MyDirectory" + "/" + "MyFile.txt"}; But, is this an eligible solution, by hard-coded the seperator? Will it work under Mac OS? (I do not have a Mac to try out)

  • How do I break down MySQL query results into categories, each with a specific number of rows?

    - by Mel
    Hello, Problem: I want to list n number of games from each genre (order not important) The following MySQL query resides inside a ColdFusion function. It is meant to list all games under a platform (for example, list all PS3 games; list all Xbox 360 games; etc...). The variable for PlatformID is passed through the URL. I have 9 genres, and I would like to list 10 games from each genre. SELECT games.GameID AS GameID, games.GameReleaseDate AS rDate, titles.TitleName AS tName, titles.TitleShortDescription AS sDesc, genres.GenreName AS gName, platforms.PlatformID, platforms.PlatformName AS pName, platforms.PlatformAbbreviation AS pAbbr FROM (((games join titles on((games.TitleID = titles.TitleID))) join genres on((genres.GenreID = games.GenreID))) join platforms on((platforms.PlatformID = games.PlatformID))) WHERE (games.PlatformID = '#ARGUMENTS.PlatformID#') ORDER BY GenreName ASC, GameReleaseDate DESC Once the query results come back I group them in ColdFusion as follows: <cfoutput query="ListGames" group="gName"> (first loop which lists genres) #ListGames.gName# <cfoutput> (nested loop which lists games) #ListGames.tName# </cfoutput> </cfoutput> The problem is that I only want 10 games from each genre to be listed. If I place a "limit" of 50 in the SQL, I will get ~ 50 games of the same genre (depending on how much games of that genre there are). The second issue is I don't want the overload of querying the database for all games when each person will only look at a few. What is the correct way to do this? Many thanks!

  • How can I add a link with a UID from a User Reference from a table in Drupal Views

    - by pduncan
    I have the following in Drupal 6: A Master CCK type which contains a User reference field and other fields. There will only be one record per user here. A View of this CCK, shown as a table, with one of the fields being the user ref from the CCK type. This field is initially shown as a user name, linking to the user profile. A Second CCK type which can have several pieces of data about a particular user. A View for this CCK type, displaying information as a table. It takes a user id as an argument (an integer) I want to click on the user name in the master view, and be directed to the detail view for this user. To do this, I tried selecting 'Output this field as a link' on the user field. The thing available for me to replace are: Fields * [field_my_user_ref_uid_1] == Content: User (field_my_user_ref) Arguments * %1 == User: Uid However, the [field_my_user_ref_uid_1] element is replaced by the user name, and %1 seems to get replaced with an empty string. How can I put the user id in here?

  • EJB3 - @Column(insertable="false") question

    - by WhiteTigerK
    Hi All, I'm building a J2SE application with EJB3 and an Oracle Express Edition DB. My problem is like that - I set an EntityBean in my project which matches a table in the DB. The table contains a column which is not nullable and has a default value. All I want is that when persisting a new data to this table using the EJB, the column's value will get its default value. This is how I set it in the project: //holds user's first name @Basic(optional = true) @Column(name = "FIRST_NAME", insertable = false, updatable = true, nullable = false) private String m_firstName; I also set it in the ORM.XML file: <basic name="firstName"> <column name="FIRST_NAME" insertable="false" updatable="true" nullable="false"/> </basic> But for some reason, when creating a new EntityBean and not setting the first name field, and then trying to persist it, i get the following exception: Exception [TOPLINK-4002] (Oracle TopLink Essentials - 2.1 (Build b60e-fcs (12/23/2008))): oracle.toplink.essentials.exceptions.DatabaseException Internal Exception: java.sql.SQLException: ORA-01400: cannot insert NULL into ("TSDB"."USERS"."FIRST_NAME") Which means that the persistence manager tries to insert the first name field although I told it not to. Am I doing something wrong here ? Thanks!

  • Parsing an arithmetic expression and building a tree from it in Java

    - by ChocolateBear
    Hi, I needed some help with creating custom trees given an arithmetic expression. Say, for example, you input this arithmetic expression: (5+2)*7 The result tree should look like: * / \ + 7 / \ 5 2 I have some custom classes to represent the different types of nodes, i.e. PlusOp, LeafInt, etc. I don't need to evaluate the expression, just create the tree, so I can perform other functions on it later. Additionally, the negative operator '-' can only have one child, and to represent '5-2', you must input it as 5 + (-2). Some validation on the expression would be required to ensure each type of operator has the correct the no. of arguments/children, each opening bracket is accompanied by a closing bracket. Also, I should probably mention my friend has already written code which converts the input string into a stack of tokens, if that's going to be helpful for this. I'd appreciate any help at all. Thanks :) (I read that you can write a grammar and use antlr/JavaCC, etc. to create the parse tree, but I'm not familiar with these tools or with writing grammars, so if that's your solution, I'd be grateful if you could provide some helpful tutorials/links for them.)

  • Starter question of declarative style SQLAlchemy relation()

    - by jfding
    I am quite new to SQLAlchemy, or even database programming, maybe my question is too simple. Now I have two class/table: class User(Base): __tablename__ = 'users' id = Column(Integer, primary_key=True) name = Column(String(40)) ... class Computer(Base): __tablename__ = 'comps' id = Column(Integer, primary_key=True) buyer_id = Column(None, ForeignKey('users.id')) user_id = Column(None, ForeignKey('users.id')) buyer = relation(User, backref=backref('buys', order_by=id)) user = relation(User, backref=backref('usings', order_by=id)) Of course, it cannot run. This is the backtrace: File "/Library/Python/2.6/site-packages/SQLAlchemy-0.5.8-py2.6.egg/sqlalchemy/orm/state.py", line 71, in initialize_instance fn(self, instance, args, kwargs) File "/Library/Python/2.6/site-packages/SQLAlchemy-0.5.8-py2.6.egg/sqlalchemy/orm/mapper.py", line 1829, in _event_on_init instrumenting_mapper.compile() File "/Library/Python/2.6/site-packages/SQLAlchemy-0.5.8-py2.6.egg/sqlalchemy/orm/mapper.py", line 687, in compile mapper._post_configure_properties() File "/Library/Python/2.6/site-packages/SQLAlchemy-0.5.8-py2.6.egg/sqlalchemy/orm/mapper.py", line 716, in _post_configure_properties prop.init() File "/Library/Python/2.6/site-packages/SQLAlchemy-0.5.8-py2.6.egg/sqlalchemy/orm/interfaces.py", line 408, in init self.do_init() File "/Library/Python/2.6/site-packages/SQLAlchemy-0.5.8-py2.6.egg/sqlalchemy/orm/properties.py", line 716, in do_init self._determine_joins() File "/Library/Python/2.6/site-packages/SQLAlchemy-0.5.8-py2.6.egg/sqlalchemy/orm/properties.py", line 806, in _determine_joins "many-to-many relation, 'secondaryjoin' is needed as well." % (self)) sqlalchemy.exc.ArgumentError: Could not determine join condition between parent/child tables on relation Package.maintainer.

  • Passing a string in Html.ActionLink in MVC 2

    - by 109221793
    I have completed the MVC Music Store application, and now am making my own modifications for practice, and also to prepare me to do similar tasks in my job. What I have done, is create a view that displays the current list of users. I have done this as I want to be able to change the passwords of users should they forget them. Here is a snippet from my view: <% foreach (MembershipUser user in Model) { %> <tr> <td><%: Html.ActionLink(user.UserName, "changeUserPassword", "StoreManager", new { username = user.UserName }) %></td> <td><%: user.LastActivityDate %></td> <td><%: user.IsLockedOut %></td> </tr> <% }%> What I want to know, is it possible to pass the username through the actionlink as I have done above. I have registered the following route in the global.asax.cs file, however I am unsure if I have done it correctly: routes.MapRoute( "AdminPassword", //Route name "{controller}/{action}/{username}", //URL with parameters new { controller = "StoreManager", action = "changeUserPassword", username = UrlParameter.Optional }); Here is my GET action: public ActionResult changeUserPassword(string username) { ViewData["username"] = username; return View(); } I have debugged through the code to find that ViewData["username"] = username doesn't populate so it looks like either I have not registered the routes properly, or I simply cannot pass the username using the actionlink like I have. I'd be grateful if someone could point me in the right direction.

  • Syntax Error with John Resig's Micro Templating after changing template tags <# {% {{ etc..

    - by optician
    I'm having a bit of trouble with John Resig's Micro templating. Can anyone help me with why it isn't working? This is the template <script type="text/html" id="row_tmpl"> test content {%=id%} {%=name%} </script> And the modified section of the engine str .replace(/[\r\t\n]/g, " ") .split("{%").join("\t") .replace(/((^|%>)[^\t]*)'/g, "$1\r") .replace(/\t=(.*?)%>/g, "',$1,'") .split("\t").join("');") .split("%}").join("p.push('") .split("\r").join("\\'") + "');}return p.join('');"); and the javascript var dataObject = { "id": "27", "name": "some more content" }; var html = tmpl("row_tmpl", dataObject); and the result, as you can see =id and =name seem to be in the wrong place? Apart from changing the template syntax blocks from <% % to {% %} I haven't changed anything. This is from Firefox.

  • Any way to pass parameters programmatically to an onclick function?

    - by RenderIn
    I have an onclick function which performs several tasks. In another javascript function I do not have access to the context variables needed to perform these tasks. To get around this I have been simply calling the onclick function directly. The problem I have now is that I'd like to perform a task after an Ajax action in the onclick completes. Is there any way for me to pass a function to the onclick method of a link? What would the onclick attribute look like? e.g. something like this: <a id="link3" href="javascript:void(0);" onclick="function(callback) { X(a); Y(b); Z(c, callback); };">click me</a> Clicking on this would pass "undefined" as the callback, while I could also call it explicitly like this: document.getElementById("link3").onclick(function() { alert("Completed all tasks"); } ); Is something like this possible? Basically I want to be able to pass an optional parameter to the onclick method, but if it's absent I want it to behave as if there were just procedural code in the onclick.

  • Kill a node in dojo.dnd.source ?

    Related to my SO issue at http://stackoverflow.com/questions/3010996/dojo-extending-dojo-dnd-source-move-not-happening-ideas/3012518#3012518 I am now almost done. I have a dnd.Source derived class - we can consider it a dnd.Source for now, that has within it a node that has a specific class. function declare_mockupSmartDndUl(){ dojo.require("dojo.dnd.Source"); dojo.provide("mockup.SmartDndUl"); dojo.declare("mockup.SmartDndUl", dojo.dnd.Source, { markupFactory: function(params, node){ //params._skipStartup = true; return new mockup.SmartDndUl(node, params); }, onDropExternal: function(source, nodes, copy){ console.debug('onDropExternal called...'); // dojo.destroy(this.getAllNodes().query(".dndInstructions")); this.inherited(arguments); var x = source.getAllNodes().length; if( x == 0 ){ newnode = document.createElement('li'); newnode.innerHTML = "Hello!"; dojo.addClass(newnode,"dndInstructions"); source.node.appendChild(newnode); } return true; // return dojo.dnd.Source.prototype.onDropExternal.call(this, source, nodes, copy); } }); } You can see the place I mean from the dojo.destroy that is commented out because it was totally n00b :) If I do this var y = this.getAllNodes().query(".dndInstructions") the nodelist in y absolutely does contain the node. Now I need t kill it, nuke it - get it out of there. Out of the dnd.Source, out of the DOM... gone. Any ideas how to do it safely? It will be the ONLY node in the list at the time we do whatever it is we are goign to do to kill the thing. Thanks!

  • Extract known pattern substring from NSString (without regex)

    - by d11wtq
    I'm really tempted to drop RegexKit (or my own libpcre wrapper) into my project in order to do this, but before I do that I want to know how Cocoa developers manage to do half of this basic stuff without really convoluted code or without linking with RegexKit or another regular expression library. I find it gobsmacking that Cocoa does not include any regular expression matching features. I've so accustomed to using regular expressions for all kinds of things that I'm lost without them. I can do what I need without them, but the code would be rather convoluted. So, Cocoa devs, I ask you, what's the "Cocoa way" to do this... The problem is an everyday problem in programming as far as I'm concerned. Cocoa must have ways of doing this with the built-in features. Note that the position of the elements I want to match changes, and sometimes "quotes" are present. Whitespace is variable. Take the following strings: Content-Type: application/xml; charset=utf-8 Content-Type: text/html; charset="iso-8859-1" Content-Type: text/plain; charset=us-ascii Content-Type: text/plain; name="example.txt"; charset=utf-8 From all of these strings, how would you go about determining the mime type (e.g. text/plain) and the charset (e.g. utf-8) using just the built-in Cocoa classes? I'd end up performing a series of -rangeOfString: and substring calls, with conditional checks to deal with the optional quotes etc. Is there a way to do this with NSScanner? The NSScanner class seems to have a pretty naive API to me. Something like C's sscanf() that works for NSString objects would be an ideal fit. Most of my string parsing needs are simple such as this example so maybe regular expressions, while I'm accustomed to them, are overkill?

  • Administrator's shortcut to batch file with double quoted parameters

    - by XXB
    Take an excruciatingly simple batch file: echo hi pause Save that as test.bat. Now, make a shortcut to test.bat. The shortcut runs the batch file, which prints "hi" and then waits for a keypress as expected. Now, add some argument to the target of the shortcut. Now you have a shortcut to: %path%\test.bat some args The shortcut runs the batch file as before. Now, run the shortcut as administrator. (This is on Windows 7 by the way.) You can use either right-click - Run as Administrator, or go to the shortcut's properties and check the box in the advanced section. Tell UAC that it's okay and once again the shortcut runs the batch file as expected. Now, change the arguments in the target of the shortcut to add double quotes: %path%\test.bat "some args" Now try the shortcut as administrator. It doesn't work this time! A command window pops up and and disappears too fast to see any error. I tried adding test.log 2&1 to the shortcut, but no log is created in this case. Try running the same shortcut (with the double quotes) but not as Administrator. It runs the batch file fine. So, it seems the behavior is not because of the double quoted parameters, and it's not because it's run as Administrator. It's some weird combination of the two. I also tried running the same command from an administrator's command window. This ran the batch file as expected without error. Running the shortcut from the command window spawned a new command window which flashed and went away. So apparently the issue is caused by a combination of administrator, the shortcut, and the double quotes. I'm totally stumped, does anyone have any idea what's going on?

  • Base 128 or 256 Encoding for the Binary Lexical Octet Adhoc Transport Protocol?

    - by Randolpho
    I'm in the process of implementing a network driver for the Binary Lexical Octet Adhoc Transport (BLOAT) protocols in the hopes of replacing the TCP/UDP/IP stack with a much more flexible XML structure. BLOAT is detailed in RFC 3252, so if you're unfamiliar with the protocol I highly recommend you read the entire RFC before providing any comments. Don't worry, it's short and sweet; you might even enjoy it. Anyway, my problem is this: BLOAT requires that the payload be Base64 encoded which doesn't make sense to me. I mean, sure, it's the internet standard for binary payloads, but there are better, more efficient encodings available: Base128 and Base256, for example. That the RFC requires Base64 and doesn't allow for any other payload encoding really bothers me. To that end, I'm considering a small optional change to the protocol. Embrace and extend, right? Anyway, I'd like to modify the payload element to accept an encoding attribute, which can extend the encoding to Base128 or Base256, or even to other encodings I can't conceive of at the moment. If the encoding attribute isn't present, Base64 would be assumed. So my question is this: should I? I mean, BLOAT is an accepted standard, even if it isn't exactly omnipresent. If I make this change, will there be compatibility issues? I don't foresee any, but perhaps you, oh great Stack Overflow Community, can? If I do implement this change, should I contact the original RFC author? Should I offer a supplemental RFC?

  • Using mem_fun_ref with boost::shared_ptr

    - by BlueRaja
    Following the advice of this page, I'm trying to get shared_ptr to call IUnknown::Release() instead of delete: IDirectDrawSurface* dds; ... //Allocate dds return shared_ptr<IDirectDrawSurface>(dds, mem_fun_ref(&IUnknown::Release)); error C2784: 'std::const_mem_fun1_ref_t<_Result,_Ty,_Arg std::mem_fun_ref(Result (_thiscall _Ty::* )(_Arg) const)' : could not deduce template argument for 'Result (_thiscall _Ty::* )(Arg) const' from 'ULONG (_cdecl IUnknown::* )(void)' error C2784: 'std::const_mem_fun_ref_t<_Result,_Ty std::mem_fun_ref(Result (_thiscall _Ty::* )(void) const)' : could not deduce template argument for 'Result (_thiscall _Ty::* )(void) const' from 'ULONG (__cdecl IUnknown::* )(void)' error C2784: 'std::mem_fun1_ref_t<_Result,_Ty,_Arg std::mem_fun_ref(Result (_thiscall _Ty::* )(_Arg))' : could not deduce template argument for 'Result (_thiscall _Ty::* )(Arg)' from 'ULONG (_cdecl IUnknown::* )(void)' error C2784: 'std::mem_fun_ref_t<_Result,_Ty std::mem_fun_ref(Result (_thiscall _Ty::* )(void))' : could not deduce template argument for 'Result (_thiscall _Ty::* )(void)' from 'ULONG (__cdecl IUnknown::* )(void)' error C2661: 'boost::shared_ptr::shared_ptr' : no overloaded function takes 2 arguments I have no idea what to make of this. My limited template/functor knowledge led me to try typedef ULONG (IUnknown::*releaseSignature)(void); shared_ptr<IDirectDrawSurface>(dds, mem_fun_ref(static_cast<releaseSignature>(&IUnknown::Release))); But to no avail. Any ideas?

  • Spaces and backslashes in Visual Studio build events

    - by gencha
    I have an application that is supposed to aid my project in terms of pre- and post-build event handling. I'm using ndesk.options for command line argument parsing. Which gave me weird results when my project path contains spaces. I thought this was the fault of ndesk.options but I guess my own application is to blame. I call my application as a post-built event like so: build.exe --in="$(ProjectDir)" --out="c:\out\" A simple foreach over args[] displays the following: --in=c:\my project" --out=c:\out" What happened is that the last " in each parameter was treated as if it was escaped. Thus the trailing backslash was removed. And the whole thing is treated as a single argument. Now I thought I was being smart by simply escaping the first " as well, like so: build.exe --in=\"$(ProjectDir)" --out=\"c:\out\" In that case the resulting args[] look like this: --path="c:\my project" --out="c:\out" The trailing backslash in the parameters is still swallowed and the first parameter is now split up. Passing this args[] to ndesk.options will then yield wrong results. How should the right command line look so that the correct elements end up in the correct args[] slots? Alternatively, how is one supposed to parse command line arguments like these with or without ndesk.options? Any suggestion is welcome. Thanks in advance

  • Can't find compiled resource bundles

    - by user351032
    I am using Adobe Flash Builder 4. I've run into this issue with my latest project, but I was able to re-create it with an almost empty project. Here is what I've done. Created a new Flex Project Created a locale/en_US folder within this project. Added a class that extends SparkDownloadProgressBar. All this class does is attempt to create a Label. When I try to debug this application, I get the following error. Error: Could not find compiled resource bundle 'components' for locale 'en_US'. at mx.resources::ResourceManagerImpl/installCompiledResourceBundle()[E:\dev\4.0.0\frameworks\projects\framework\src\mx\resources\ResourceManagerImpl.as:340] at mx.resources::ResourceManagerImpl/installCompiledResourceBundles()[E:\dev\4.0.0\frameworks\projects\framework\src\mx\resources\ResourceManagerImpl.as:269] at mx.resources::ResourceManagerImpl/processInfo()[E:\dev\4.0.0\frameworks\projects\framework\src\mx\resources\ResourceManagerImpl.as:387] at mx.resources::ResourceManagerImpl()[E:\dev\4.0.0\frameworks\projects\framework\src\mx\resources\ResourceManagerImpl.as:122] at mx.resources::ResourceManager$/getInstance()[E:\dev\4.0.0\frameworks\projects\framework\src\mx\resources\ResourceManager.as:111] at mx.core::UIComponent()[E:\dev\4.0.0\frameworks\projects\framework\src\mx\core\UIComponent.as:3728] at spark.components.supportClasses::TextBase()[E:\dev\4.0.0\frameworks\projects\spark\src\spark\components\supportClasses\TextBase.as:154] at spark.components::Label()[E:\dev\4.0.0\frameworks\projects\spark\src\spark\components\Label.as:384] at Preloader()[C:\SVN\Games\Social\Test\src\Preloader.as:21] at mx.preloaders::Preloader/initialize()[E:\dev\4.0.0\frameworks\projects\framework\src\mx\preloaders\Preloader.as:253] at mx.managers::SystemManager/http://www.adobe.com/2006/flex/mx/internal::initialize()[E:\dev\4.0.0\frameworks\projects\framework\src\mx\managers\SystemManager.as:1925] at mx.managers::SystemManager/initHandler()[E:\dev\4.0.0\frameworks\projects\framework\src\mx\managers\SystemManager.as:2419] The Flex Compiler/Additional Compiler Arguments section does contain "-locale en_US", but I do not want to just remove this as I am planning to have this load different property files based on the localization region at run-time and how I understand it, I will need to add each locale that I am planning to use on the compile argument line. I am at a loss as to how to attack this problem. If you need anymore information from me to help with this, I will be more than happy to provide it. Thanks ahead of time for the help!

  • javascript form validation - positioning

    - by Holian
    Dear Masters! I have little snippet for validatin' my form. I need help to position the error messages, because now all message appear in the filed, so the user can't see it, and so its very annoying. $(document).ready(function() { jQuery.validator.addMethod("lettersonly", function(value, element) { return this.optional(element) || /^[a-zoöüóúéáuí ]+$/i.test(value); }, "<?php echo $lettersonly; ?>"); $("#regval").validate({ rules: { name: { required: true, minlength: 5, maxlength:30, lettersonly: true }, nick: { required: true, minlength: 3, maxlength:12 }, pass1: { required: true, minlength: 5 }, pass2: { required: true, minlength: 5, equalTo: "#pass1" }, messages: { full: { required: ".....", minlength: "....", maxlength: "...." }, nick: { required: "....", minlength: "....", maxlength: "...." }, pass1: { required: "....", minlength: "..." }, pass2: { required: "....", minlength: "....", equalTo: "...." }, }); }); </script>
