• wxPthon problems with Wrapping StaticText

  - by Scott B

  Hello. I am having an issue with wxPython. A simplified version of the code is posted below (white space, comments, etc removed to reduce size - but the general format to my program is kept roughly the same). When I run the script, the static text correctly wraps as it should, but the other items in the panel do not move down (they act as if the statictext is only one line and thus not everything is visible). If I manually resize the window/frame, even just a tiny amount, everything gets corrected and displays as it is should. I took screen shots to show this behavior, but I just created this account and thus don't have the required 10 reputation points to be allowed to post pictures. Why does it not display correctly to begin with? I've tried all sorts of combination's of GetParent().Refresh() or Update() and GetTopLevelParent().Update() or Refresh(). I've tried everything I can think of but cannot get it to display correctly without manually resizing the frame/window. Once re-sized, it works exactly as I want it to. Information: Windows XP Python 2.5.2 wxPython 2.8.11.0 (msw-unicode) Any suggestions? Thanks! Code: #! /usr/bin/python import wx class StaticWrapText(wx.PyControl): def __init__(self, parent, id=wx.ID_ANY, label='', pos=wx.DefaultPosition, size=wx.DefaultSize, style=wx.NO_BORDER, validator=wx.DefaultValidator, name='StaticWrapText'): wx.PyControl.__init__(self, parent, id, pos, size, style, validator, name) self.statictext = wx.StaticText(self, wx.ID_ANY, label, style=style) self.wraplabel = label #self.wrap() def wrap(self): self.Freeze() self.statictext.SetLabel(self.wraplabel) self.statictext.Wrap(self.GetSize().width) self.Thaw() def DoGetBestSize(self): self.wrap() #print self.statictext.GetSize() self.SetSize(self.statictext.GetSize()) return self.GetSize() class TestPanel(wx.Panel): def __init__(self, *args, **kwargs): # Init the base class wx.Panel.__init__(self, *args, **kwargs) self.createControls() def createControls(self): # --- Panel2 ------------------------------------------------------------- self.Panel2 = wx.Panel(self, -1) msg1 = 'Below is a List of Files to be Processed' staticBox = wx.StaticBox(self.Panel2, label=msg1) Panel2_box1_v1 = wx.StaticBoxSizer(staticBox, wx.VERTICAL) Panel2_box2_h1 = wx.BoxSizer(wx.HORIZONTAL) Panel2_box3_v1 = wx.BoxSizer(wx.VERTICAL) self.wxL_Inputs = wx.ListBox(self.Panel2, wx.ID_ANY, style=wx.LB_EXTENDED) sz = dict(size=(120,-1)) wxB_AddFile = wx.Button(self.Panel2, label='Add File', **sz) wxB_DeleteFile = wx.Button(self.Panel2, label='Delete Selected', **sz) wxB_ClearFiles = wx.Button(self.Panel2, label='Clear All', **sz) Panel2_box3_v1.Add(wxB_AddFile, 0, wx.TOP, 0) Panel2_box3_v1.Add(wxB_DeleteFile, 0, wx.TOP, 0) Panel2_box3_v1.Add(wxB_ClearFiles, 0, wx.TOP, 0) Panel2_box2_h1.Add(self.wxL_Inputs, 1, wx.ALL|wx.EXPAND, 2) Panel2_box2_h1.Add(Panel2_box3_v1, 0, wx.ALL|wx.EXPAND, 2) msg = 'This is a long line of text used to test the autowrapping ' msg += 'static text message.

• Suggestions for duplicate file finder algorithm (using C)

  - by Andrei Ciobanu

  Hello, I wanted to write a program that test if two files are duplicates (have exactly the same content). First I test if the files have the same sizes, and if they have i start to compare their contents. My first idea, was to "split" the files into fixed size blocks, then start a thread for every block, fseek to startup character of every block and continue the comparisons in parallel. When a comparison from a thread fails, the other working threads are canceled, and the program exits out of the thread spawning loop. The code looks like this: dupf.h #ifndef __NM__DUPF__H__ #define __NM__DUPF__H__ #define NUM_THREADS 15 #define BLOCK_SIZE 8192 /* Thread argument structure */ struct thread_arg_s { const char *name_f1; /* First file name */ const char *name_f2; /* Second file name */ int cursor; /* Where to seek in the file */ }; typedef struct thread_arg_s thread_arg; /** * 'arg' is of type thread_arg. * Checks if the specified file blocks are * duplicates. */ void *check_block_dup(void *arg); /** * Checks if two files are duplicates */ int check_dup(const char *name_f1, const char *name_f2); /** * Returns a valid pointer to a file. * If the file (given by the path/name 'fname') cannot be opened * in 'mode', the program is interrupted an error message is shown. **/ FILE *safe_fopen(const char *name, const char *mode); #endif dupf.c #include <errno.h> #include <pthread.h> #include <stdio.h> #include <stdlib.h> #include <string.h> #include <sys/types.h> #include <sys/stat.h> #include <unistd.h> #include "dupf.h" FILE *safe_fopen(const char *fname, const char *mode) { FILE *f = NULL; f = fopen(fname, mode); if (f == NULL) { char emsg[255]; sprintf(emsg, "FOPEN() %s\t", fname); perror(emsg); exit(-1); } return (f); } void *check_block_dup(void *arg) { const char *name_f1 = NULL, *name_f2 = NULL; /* File names */ FILE *f1 = NULL, *f2 = NULL; /* Streams */ int cursor = 0; /* Reading cursor */ char buff_f1[BLOCK_SIZE], buff_f2[BLOCK_SIZE]; /* Character buffers */ int rchars_1, rchars_2; /* Readed characters */ /* Initializing variables from 'arg' */ name_f1 = ((thread_arg*)arg)->name_f1; name_f2 = ((thread_arg*)arg)->name_f2; cursor = ((thread_arg*)arg)->cursor; /* Opening files */ f1 = safe_fopen(name_f1, "r"); f2 = safe_fopen(name_f2, "r"); /* Setup cursor in files */ fseek(f1, cursor, SEEK_SET); fseek(f2, cursor, SEEK_SET); /* Initialize buffers */ rchars_1 = fread(buff_f1, 1, BLOCK_SIZE, f1); rchars_2 = fread(buff_f2, 1, BLOCK_SIZE, f2); if (rchars_1 != rchars_2) { /* fread failed to read the same portion. * program cannot continue */ perror("ERROR WHEN READING BLOCK"); exit(-1); } while (rchars_1-->0) { if (buff_f1[rchars_1] != buff_f2[rchars_1]) { /* Different characters */ fclose(f1); fclose(f2); pthread_exit("notdup"); } } /* Close streams */ fclose(f1); fclose(f2); pthread_exit("dup"); } int check_dup(const char *name_f1, const char *name_f2) { int num_blocks = 0; /* Number of 'blocks' to check */ int num_tsp = 0; /* Number of threads spawns */ int tsp_iter = 0; /* Iterator for threads spawns */ pthread_t *tsp_threads = NULL; thread_arg *tsp_threads_args = NULL; int tsp_threads_iter = 0; int thread_c_res = 0; /* Thread creation result */ int thread_j_res = 0; /* Thread join res */ int loop_res = 0; /* Function result */ int cursor; struct stat buf_f1; struct stat buf_f2; if (name_f1 == NULL || name_f2 == NULL) { /* Invalid input parameters */ perror("INVALID FNAMES\t"); return (-1); } if (stat(name_f1, &buf_f1) != 0 || stat(name_f2, &buf_f2) != 0) { /* Stat fails */ char emsg[255]; sprintf(emsg, "STAT() ERROR: %s %s\t", name_f1, name_f2); perror(emsg); return (-1); } if (buf_f1.st_size != buf_f2.st_size) { /* File have different sizes */ return (1); } /* Files have the same size, function exec. is continued */ num_blocks = (buf_f1.st_size / BLOCK_SIZE) + 1; num_tsp = (num_blocks / NUM_THREADS) + 1; cursor = 0; for (tsp_iter = 0; tsp_iter < num_tsp; tsp_iter++) { loop_res = 0; /* Create threads array for this spawn */ tsp_threads = malloc(NUM_THREADS * sizeof(*tsp_threads)); if (tsp_threads == NULL) { perror("TSP_THREADS ALLOC FAILURE\t"); return (-1); } /* Create arguments for every thread in the current spawn */ tsp_threads_args = malloc(NUM_THREADS * sizeof(*tsp_threads_args)); if (tsp_threads_args == NULL) { perror("TSP THREADS ARGS ALLOCA FAILURE\t"); return (-1); } /* Initialize arguments and create threads */ for (tsp_threads_iter = 0; tsp_threads_iter < NUM_THREADS; tsp_threads_iter++) { if (cursor >= buf_f1.st_size) { break; } tsp_threads_args[tsp_threads_iter].name_f1 = name_f1; tsp_threads_args[tsp_threads_iter].name_f2 = name_f2; tsp_threads_args[tsp_threads_iter].cursor = cursor; thread_c_res = pthread_create( &tsp_threads[tsp_threads_iter], NULL, check_block_dup, (void*)&tsp_threads_args[tsp_threads_iter]); if (thread_c_res != 0) { perror("THREAD CREATION FAILURE"); return (-1); } cursor+=BLOCK_SIZE; } /* Join last threads and get their status */ while (tsp_threads_iter-->0) { void *thread_res = NULL; thread_j_res = pthread_join(tsp_threads[tsp_threads_iter], &thread_res); if (thread_j_res != 0) { perror("THREAD JOIN FAILURE"); return (-1); } if (strcmp((char*)thread_res, "notdup")==0) { loop_res++; /* Closing other threads and exiting by condition * from loop. */ while (tsp_threads_iter-->0) { pthread_cancel(tsp_threads[tsp_threads_iter]); } } } free(tsp_threads); free(tsp_threads_args); if (loop_res > 0) { break; } } return (loop_res > 0) ? 1 : 0; } The function works fine (at least for what I've tested). Still, some guys from #C (freenode) suggested that the solution is overly complicated, and it may perform poorly because of parallel reading on hddisk. What I want to know: Is the threaded approach flawed by default ? Is fseek() so slow ? Is there a way to somehow map the files to memory and then compare them ?

• ant ftp doesn't download files in subdirectories

  - by Kristof Neirynck

  Hello, I'm trying to download files in subdirectories from an ftp server with ant. The exact set of files is known. Some of them are in subdirectories. Ant only seems to download the ones in the root directory. It does work if I download all files without listing them. The first ftp action should do the exact same thing as the second. Instead it complains about "Hidden files" and seems to prefix the paths with "\\". Does anyone know what's wrong here? Is this a bug in commons-net? build.xml <?xml version="1.0" encoding="utf-8"?> <project name="example" default="example" basedir="."> <taskdef name="ftp" classname="org.apache.tools.ant.taskdefs.optional.net.FTP" /> <target name="example"> <!-- 2 files retrieved --> <ftp action="get" verbose="true" server="localhost" userid="example" password="example"> <fileset dir="downloads" casesensitive="false" includes="root1.txt,root2.txt,a/a.txt,a/b/ab.txt,c/c.txt" /> </ftp> <!-- 5 files retrieved --> <ftp action="get" verbose="true" server="localhost" userid="example" password="example"> <fileset dir="downloads" casesensitive="false" includes="**/*" /> </ftp> </target> </project> run_ant.bat @ECHO OFF PUSHD %~dp0 SET CLASSPATH= SET ANT_HOME=C:\apache-ant-1.8.0 SET ant=%ANT_HOME%\bin\ant.bat SET antoptions=-nouserlib -noclasspath -d SET ftpjars=^ -lib lib\jakarta-oro-2.0.8.jar ^ -lib lib\commons-net-2.0.jar CALL %ant% %antoptions% %ftpjars% > output.txt POPD output.txt Unable to locate tools.jar.

• Using the HTML5 &lt;input type=&quot;file&quot; multiple=&quot;multiple&quot;&gt; Tag in ASP.NET

  - by Rick Strahl

  Per HTML5 spec the <input type="file" /> tag allows for multiple files to be picked from a single File upload button. This is actually a very subtle change that's very useful as it makes it much easier to send multiple files to the server without using complex uploader controls. Please understand though, that even though you can send multiple files using the <input type="file" /> tag, the process of how those files are sent hasn't really changed - there's still no progress information or other hooks that allow you to automatically make for a nicer upload experience without additional libraries or code. For that you will still need some sort of library (I'll post an example in my next blog post using plUpload). All the new features allow for is to make it easier to select multiple images from disk in one operation. Where you might have required many file upload controls before to upload several files, one File control can potentially do the job. How it works To create a file input box that allows with multiple file support you can simply do:<form method="post" enctype="multipart/form-data"> <label>Upload Images:</label> <input type="file" multiple="multiple" name="File1" id="File1" accept="image/*" /> <hr /> <input type="submit" id="btnUpload" value="Upload Images" /> </form> Now when the file open dialog pops up - depending on the browser and whether the browser supports it - you can pick multiple files. Here I'm using Firefox using the thumbnail preview I can easily pick images to upload on a form: Note that I can select multiple images in the dialog all of which get stored in the file textbox. The UI for this can be different in some browsers. For example Chrome displays 3 files selected as text next to the Browse… button when I choose three rather than showing any files in the textbox. Most other browsers display the standard file input box and display the multiple filenames as a comma delimited list in the textbox. Note that you can also specify the accept attribute in the <input> tag, which specifies a mime-type to specify what type of content to allow.Here I'm only allowing images (image/*) and the browser complies by just showing me image files to display. Likewise I could use text/* for all text formats registered on the machine or text/xml to only show XML files (which would include xml,xst,xsd etc.). Capturing Files on the Server with ASP.NET When you upload files to an ASP.NET server there are a couple of things to be aware of. When multiple files are uploaded from a single file control, they are assigned the same name. In other words if I select 3 files to upload on the File1 control shown above I get three file form variables named File1. This means I can't easily retrieve files by their name:HttpPostedFileBase file = Request.Files["File1"]; because there will be multiple files for a given name. The above only selects the first file. Instead you can only reliably retrieve files by their index. Below is an example I use in app to capture a number of images uploaded and store them into a database using a business object and EF 4.2.for (int i = 0; i < Request.Files.Count; i++) { HttpPostedFileBase file = Request.Files[i]; if (file.ContentLength == 0) continue; if (file.ContentLength > App.Configuration.MaxImageUploadSize) { ErrorDisplay.ShowError("File " + file.FileName + " is too large. Max upload size is: " + App.Configuration.MaxImageUploadSize); return View("UploadClassic",model); } var image = new ClassifiedsBusiness.Image(); var ms = new MemoryStream(16498); file.InputStream.CopyTo(ms); image.Entered = DateTime.Now; image.EntryId = model.Entry.Id; image.ContentType = "image/jpeg"; image.ImageData = ms.ToArray(); ms.Seek(0, SeekOrigin.Begin); // resize image if necessary and turn into jpeg Bitmap bmp = Imaging.ResizeImage(ms.ToArray(), App.Configuration.MaxImageWidth, App.Configuration.MaxImageHeight); ms.Close(); ms = new MemoryStream(); bmp.Save(ms,ImageFormat.Jpeg); image.ImageData = ms.ToArray(); bmp.Dispose(); ms.Close(); model.Entry.Images.Add(image); } This works great and also allows you to capture input from multiple input controls if you are dealing with browsers that don't support multiple file selections in the file upload control. The important thing here is that I iterate over the files by index, rather than using a foreach loop over the Request.Files collection. The files collection returns key name strings, rather than the actual files (who thought that was good idea at Microsoft?), and so that isn't going to work since you end up getting multiple keys with the same name. Instead a plain for loop has to be used to loop over all files. Another Option in ASP.NET MVC If you're using ASP.NET MVC you can use the code above as well, but you have yet another option to capture multiple uploaded files by using a parameter for your post action method.public ActionResult Save(HttpPostedFileBase[] file1) { foreach (var file in file1) { if (file.ContentLength < 0) continue; // do something with the file }} Note that in order for this to work you have to specify each posted file variable individually in the parameter list. This works great if you have a single file upload to deal with. You can also pass this in addition to your main model to separate out a ViewModel and a set of uploaded files:public ActionResult Edit(EntryViewModel model,HttpPostedFileBase[] uploadedFile) You can also make the uploaded files part of the ViewModel itself - just make sure you use the appropriate naming for the variable name in the HTML document (since there's Html.FileFor() extension). Browser Support You knew this was coming, right? The feature is really nice, but unfortunately not supported universally yet. Once again Internet Explorer is the problem: No shipping version of Internet Explorer supports multiple file uploads. IE10 supposedly will, but even IE9 does not. All other major browsers - Chrome, Firefox, Safari and Opera - support multi-file uploads in their latest versions. So how can you handle this? If you need to provide multiple file uploads you can simply add multiple file selection boxes and let people either select multiple files with a single upload file box or use multiples. Alternately you can do some browser detection and if IE is used simply show the extra file upload boxes. It's not ideal, but either one of these approaches makes life easier for folks that use a decent browser and leaves you with a functional interface for those that don't. Here's a UI I recently built as an alternate uploader with multiple file upload buttons: I say this is my 'alternate' uploader - for my primary uploader I continue to use an add-in solution. Specifically I use plUpload and I'll discuss how that's implemented in my next post. Although I think that plUpload (and many of the other packaged JavaScript upload solutions) are a better choice especially for large uploads, for simple one file uploads input boxes work well enough. The advantage of this solution is that it's very easy to handle on the server side. Any of the JavaScript controls require special handling for uploads which I'll also discuss in my next post.© Rick Strahl, West Wind Technologies, 2005-2012Posted in HTML5  ASP.NET  MVC   Tweet !function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src="//platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs"); (function() { var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true; po.src = 'https://apis.google.com/js/plusone.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s); })();

• Delphi - threads and FindFirst function

  - by radu-barbu

  Hi, I'm encountering a big problem when i'm trying to make a recursive search function inside a thread (using delphi 7) bellow is the code: TParcFicDir = class(TThread) private several variables.. protected procedure Execute; override; public constructor Create(CreateSuspended: Boolean); constructor TParcFicDir.Create(CreateSuspended: Boolean); begin inherited Create(CreateSuspended); end; procedure TParcFicDir.Execute; begin try FindFiles(FStartDir,FMask);//'c:\' and '*.*' except on e:Exception do end; end; procedure TParcFicDir.FindFiles(StartDir, FileMask: string); var wTmp : string; f:TextFile; wTempSR:TSearchRec; function Search(StartDir, FileMask: string): string; var SR : TSearchRec; IsFound : Boolean; files : integer; dirs : integer; t : string; begin try files := 0; dirs := 0; if StartDir[length(StartDir)] <> '\' then StartDir := StartDir + '\'; try IsFound := (FindFirst(StartDir + '*.*', faAnyFile, SR) = 0);// here the thread gets interrupted except on e: Exception do end; while IsFound do begin if (SR.Name <> '.') and (SR.Name <> '..') then if ((SR.Attr and faDirectory) <> 0) then if FScanDirs then begin inc(dirs); t := Search(StartDir + SR.Name, FileMask); try files := files + strtoint(copy((t), 0, pos('#', t) - 1));//old code, don't take on calcul; Delete(t, 1, pos('#', t)); dirs := dirs + strtoint(t); except on e: Exception do end; begin t := StartDir + SR.Name; wTmp := t; wtmp := ''; Inc(FDirNo); writeln(f,t); inc(filno); end; end else if ScanFiles then begin inc(filno); inc(files); end; IsFound := FindNext(SR) = 0; end; Result := IntToStr(files) + '#' + IntToStr(dirs); sysutils.FindClose(SR); except on e: Exception do end; end; begin filno := 0; try try if trim(FPathFileTmp)<>'' then AssignFile(f, FPathFileTmp+'Temp.bak') else AssignFile(f,ExtractFileDir(GetDllName)+'\Temp.bak'); Rewrite(f); Search(StartDir, FileMask); if StartDir[length(StartDir)] = '\' then delete(StartDir, length(StartDir), 1); wTmp := StartDir; wTmp := ''; if FindFirst(StartDir, faDirectory, wTempSR) = 0 then writeln(f); writeln(f); CloseFile(f); except on e: Exception do end; finally end; end; ok, probably the code is a little messed up, but i don't understand why the thread ends at 'findfirst' part....i googled it, no results. any help will be appreciated! Thanks in advance

• C# file write permission issue under "Program Files" folder

  - by George2

  Hello everyone, I am using inno setup to make a installation package for my application, and my application is written by C# + .Net 2.0 + VSTS 2008. Inno setup = http://www.jrsoftware.org/isinfo.php and I install my application under Program Files/Foo folder (Foo is my application name). My application is targeting to Windows Vista. The issue I found is my program cannot write to the folder Program Files/Foo. And I need the permission of write to this folder in order to save some configuration files. The strange thing I notice is the folder Program Files/Foo is marked as readonly and I have checked all folders under Program Files are marked with read only, such as Office. My questions are, Why all folders are marked as read only under Program Files? It means we should not write to individual application folders under Program Files? If not, where should we write information to disk like user last selected configuration information of an individual application? If we could write to individual application folders under Program Files, what is the solution? I do not want my application to Run As administrator to solve this issue, and if there are solution to write to this folder, I want to require minimal permission if possible. thanks in advance, George

• Problems importing WAR files in Eclipse?

  - by CitadelCSAlum

  I was unfortunately forced to result to uploading a WAR file as my backup for a web application I am working on. Luckily I have the most recent WAR file available. I am using Eclipse IDE and am using the Web Tools plugin for all the J2EE work that I am doing with the Dynamic Web Application Project. When I imported my WAR file, and ran it on a local server, everything works fine. The problem I a ran into is that in the Java Resources/src folder that all my packages and .java files were now only consists of all the same packages, but they are empty. I checked to see if I could find the files and I found the .class files in an "Imported files" folder that is not accessible in the Eclipse Project Explorer. I believe that I need to do some type of build or something so that my .java files are available for me, but unfortunately this is one area where I lack. One thing I would also like to know is, one way or the other, am I able to obtain the .java source code files if I have access to the .class files? Also, I would like to configure this environment as it was before where my Java Resources:src folder contaiend the packages and .java files.

• Access/Download server files, not in site root, with PHP

  - by user271619

  Usually I save documents (images, mpegs, excel, word docs, etc...) for my friends or family on my website's root, inside a directory called /files/ or something similar. Nothing too uncommon. But, I have been playing with user session control, and allowing users to upload files to the dedicated /files/ directory. (the file names are saved in a db, with that user's ID) But, that means other people could try to guess and locate other people's files. I do randomize the file names, upon upload. And I stop the apache from displaying the /files/ directory content. However, I'd like to start saving the files outside of the website's root. This way it can't be accessible via the browser. I don't have any code to show, but I didn't want to even start on this endeavor if it's not able to be accomplished. I did find this snippet that shows how to display an image, from outside your website root: $file = $_GET['file']; $fileDir = '/path/to/files/'; if (file_exists($fileDir . $file)) { // Note: You should probably do some more checks // on the filetype, size, etc. $contents = file_get_contents($fileDir . $file); // Note: You should probably implement some kind // of check on filetype header('Content-type: image/jpeg'); echo $contents; } ? Maybe I can use this for any file type, but has anyone heard of a better way to allow users (logged in) to access their files from online, but not letting other users has similar access?

• Visual Studio Linked Files Directory Structure

  - by jeffn825

  I have two versions of a project. One for Silverlight and one for .NET. The SL project has the vast majority of the code base in it. I want to globally add all files from the SL project into the .NET version as linked files. I've managed to do so successfully like this in the csproj file for the .NET version: <Compile Include="..\MyProj.Common.SL\**\*.cs" Exclude="..\MyProj.Common\Properties\**"> Unfortunately, this adds all the files right to the root of my project... so I end up with a long unreadable list of linked files in the .NET project. I really really really don't want to have to maintain an entire duplicate directory structure by hand and deal with directory name changes and file name changes and whatnot. So, is there any way to have Visual Studio preserve the directory structure when adding linked files in the wildcard manner above? Or is there at least a way of making it group all the linked files together under a directory in the .NET project like MyProj.Common.SL.Links? The very closest I've come is to set the <Visible>false</Visible> under the <Compile> tag, which effectively removes the long unreadable list of 300+ files....but unfortunately this screws up Resharper, which no longer sees those files as valid and it goes crazy on all the projects that reference the .NET project. If I could figure out a way of making Resharper not get all messed up, that would be an acceptable solution too... Any suggestions? Thanks.

• IIS 6+ASP.NET - many temp files generated

  - by moshe_ravid

  I have a ASP.NET + some .NET web-services running on IIS 6 (win 2003 server). The issue is that IIS is generating a lot (!) of files in "c:\WINDOWS\Temp" directory. a lot of files means thousands of files, which get to more than 3G of size so far. The files are generated by this command: C:\WINDOWS\SysWOW64\inetsrv "C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\csc.exe" /t:library /utf8output /R:"C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\vfagt\113819dd\db0d5802\assembly\dl3\fedc6ef1\006e24d8_3bc9ca01\VfAgentWService.DLL" /R:"C:\WINDOWS\assembly\GAC_MSIL\System.Web.Services\2.0.0.0__b03f5f7f11d50a3a\System.Web.Services.dll" /R:"C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\mscorlib.dll" /R:"C:\WINDOWS\assembly\GAC_MSIL\System.Xml\2.0.0.0__b77a5c561934e089\System.Xml.dll" /R:"C:\WINDOWS\assembly\GAC_MSIL\System\2.0.0.0__b77a5c561934e089\System.dll" /out:"C:\WINDOWS\TEMP\9i_i2bmg.dll" /debug- /optimize+ /nostdlib /D:_DYNAMIC_XMLSERIALIZER_COMPILATION "C:\WINDOWS\TEMP\9i_i2bmg.0.cs" The files in the temp directory are pairs of *.out & *.err, where the *.err file is zero size, and the *.out file contains the compilation output messages. What is causing IIS to generate so many files? How can I prevent it? UPDATE: The problem is that the command i described above (csc.exe) is being executed many (many) times, causing the .out & .err to be generated so many times, until it consumes the disk space. So - my question is: what is causing this command to run so many times? (i don't have that many .aspx & .asmx files in my web app). Thanks, Moe

• Programatically rebuild .exd-files when loading VBA

  - by aspartame

  Hi, After updating Microsoft Office 2007 to Office 2010 some custom VBA scripts embedded in our software failed to compile with the following error message: Object library invalid or contains references to object definitions that could not be found. As far as I know, this error is a result of a security update from Microsoft (Microsoft Security Advisory 960715). When adding ActiveX-controls to VBA scripts, information about the controls are stored in cache files on the local hard drive (.exd-files). The security update modified some of these controls, but the .exd-files were not automatically updated. When the VBA scripts try to load the old versions of the controls stored in the cached files, the error occurs. These cache-files must be removed from the hard drive in order for the controls to load successfully (which will create new, updated .exd-files automatically). What I would like to do is to programatically (using Visual C++) remove the outdated .exd-files when our software loads. When opening a VBA project using CApcProject::ApcProject.Open I set the following flag:axProjectThrowAwayCompiledState. TestHR(ApcProject.Open(pHost, (MSAPC::AxProjectFlag) (MSAPC::axProjectNormal | MSAPC::axProjectThrowAwayCompiledState))); According to the documentation, this flag should cause the VBA project to be recompiled and the temporary files to be deleted and rebuilt. I've also tried to update the checksum of the host application type library which should have the same effect. However none of these fixes seem to do the job and I'm running out of ideas. Help is very much appreciated!

• Find files on a remote server

  - by Peter Kelly

  I have a web-service that resides on serverA. The webservice will be responsible for finding files of a certain type in a virtual directory on serverB and then returning the full URL to the files. I have the service working if the files are located on the same machine - this is straight-forward enough. My question is what is the best way to find all files of a certain type (say *.xml) in all directories below a known virtual directory on a remote server? So for example, the webservice is on http://ServerA/service.asmx and the virtual directory is located at http://serverB/virtualdirectory So in this code, obviously the DirectoryInfo will not take a path to the remote server - how do I access this so I can find the files it contains? How do I then get the full URL to a file found on that remote server? DirectoryInfo updateDirectory = new DirectoryInfo(path); FileInfo[] files = updateDirectory.GetFiles("*.xml", SearchOption.AllDirectories); foreach (FileInfo fileInfo in files) { // Get URL to the file } I cannot have the files and the service on the same server - IT decision that is out of my hands. Thanks!

• jQuery recursive function to upload many files while giving the user some feedback

  - by checcco

  Hi guys, I'm trying to write a jQuery function to let users upload many files at once. Here's the function I thought to give the user some feedback about the upload process progress. function uploadFiles(numbersOfFiles, start) { $("#info").html(start + " files uploaded"); $.post('upload.php', { start: start }, function (data) { start += 5; if (start < numbersOfFiles) { $("#info").html(start + " files uploaded"); uploadFiles(numbersOfFiles, start); } else { $("#info").html("All files have been uploaded"); } }); } The function calls a php script to upload 5 files, then if there are more files to upload it calls the script again. The whole process works. I've tried it with 100 files. The only thing that doesn't work is the #info div updating. The div get updated the first time and then again only to show "All files have been uploaded". So there's no feedback for the user about the uploading process. I can't understand why... Any help?

• Cisco 881 losing NAT NVI translation config after reload

  - by MasterRoot24

  This is a weird one, so I'll try to explain in as much detail as I can so I'm giving the whole picture. As I've mentioned in my other questions, I'm in the process of setting up a new Cisco 881 as my WAN router and NAT firewall. I'm facing an issue where NAT NVI rules that I have configured are not enabled after a reload of the router, regardless of the fact that they are present in the startup-config. In order to clarify this a little, here's the relevant section of my current running-config: Router1#show running-config | include nat source ip nat source list 1 interface FastEthernet4 overload ip nat source list 2 interface FastEthernet4 overload ip nat source static tcp 192.168.1.x 1723 interface FastEthernet4 1723 ip nat source static tcp 192.168.1.x 80 interface FastEthernet4 80 ip nat source static tcp 192.168.1.x 443 interface FastEthernet4 443 ip nat source static tcp 192.168.1.x 25 interface FastEthernet4 25 ip nat source static tcp 192.168.1.x 587 interface FastEthernet4 587 ip nat source static tcp 192.168.1.x 143 interface FastEthernet4 143 ip nat source static tcp 192.168.1.x 993 interface FastEthernet4 993 ...and here's the mappings 'in action': Router1#show ip nat nvi translations | include --- tcp <WAN IP>:25 192.168.1.x:25 --- --- tcp <WAN IP>:80 192.168.1.x:80 --- --- tcp <WAN IP>:143 192.168.1.x:143 --- --- tcp <WAN IP>:443 192.168.1.x:443 --- --- tcp <WAN IP>:587 192.168.1.x:587 --- --- tcp <WAN IP>:993 192.168.1.x:993 --- --- tcp <WAN IP>:1723 192.168.1.x:1723 --- --- ...and here's proof that the mappings are saved to startup-config: Router1#show startup-config | include nat source ip nat source list 1 interface FastEthernet4 overload ip nat source list 2 interface FastEthernet4 overload ip nat source static tcp 192.168.1.x 1723 interface FastEthernet4 1723 ip nat source static tcp 192.168.1.x 80 interface FastEthernet4 80 ip nat source static tcp 192.168.1.x 443 interface FastEthernet4 443 ip nat source static tcp 192.168.1.x 25 interface FastEthernet4 25 ip nat source static tcp 192.168.1.x 587 interface FastEthernet4 587 ip nat source static tcp 192.168.1.x 143 interface FastEthernet4 143 ip nat source static tcp 192.168.1.x 993 interface FastEthernet4 993 However, look what happens after a reload of the router: Router1#reload Proceed with reload?

I presume that this is because my interfaces are using ip nat enable for use with NVI mappings, instead of ip nat inside/outside. So, I re-apply the mappings: Router1#configure ter Router1#configure terminal Enter configuration commands, one per line. End with CNTL/Z. Router1(config)#ip nat source static tcp 192.168.1.2 1723 interface FastEthernet4 1723 Router1(config)#ip nat source static tcp 192.168.1.2 80 interface FastEthernet4 80 Router1(config)#ip nat source static tcp 192.168.1.2 443 interface FastEthernet4 443 Router1(config)#ip nat source static tcp 192.168.1.2 25 interface FastEthernet4 25 Router1(config)#ip nat source static tcp 192.168.1.2 587 interface FastEthernet4 587 Router1(config)#ip nat source static tcp 192.168.1.2 143 interface FastEthernet4 143 Router1(config)#ip nat source static tcp 192.168.1.2 993 interface FastEthernet4 993 Router1(config)#end ... then they show up correctly: Router1#show ip nat nvi translations | include --- tcp 188.222.181.173:25 192.168.1.2:25 --- --- tcp 188.222.181.173:80 192.168.1.2:80 --- --- tcp 188.222.181.173:143 192.168.1.2:143 --- --- tcp 188.222.181.173:443 192.168.1.2:443 --- --- tcp 188.222.181.173:587 192.168.1.2:587 --- --- tcp 188.222.181.173:993 192.168.1.2:993 --- --- tcp 188.222.181.173:1723 192.168.1.2:1723 --- --- Router1# Router1#show ip nat translations | include --- Router1# ... furthermore, now from both WAN and LAN, the services mapped above now work until the next reload.

• Template inheritence c++

  - by Chris Condy

  I have made a template singleton class, I have also made a data structure that is templated. My question is; how do I make my templated data structure inherit from a singleton so you can only have one float type of this structure? I have tested both seperate and have found no problems. Code provided under... (That is the problem) template <class Type> class AbstractRManagers : public Singleton<AbstractRManagers<Type> > The problem is the code above doesn't work I get alot of errors. I cant get it to no matter what I do template a templated singleton class... I was asking for maybe advice or maybe if the code above is incorrect guidence? #ifndef SINGLETON_H #define SINGLETON_H template <class Type> class Singleton { public: virtual ~Singleton();

• Quick Java question about variables

  - by Spencer

  I'm declaring a variable: private static final String filename = "filename.txt"; First, does the order of private static final matter? If not, is there a standard excepted sequence or convention? Second, the filename in my application is fixed. Is this the best was to store it's value? Thanks, Spencer

• Copy android.R.layout to my project

  - by eric

  Good advice from CommonWare and Steve H but it's not as easy to me as I first thought. Based on their advice I'm trying to copy android.R.layout to my project to ensure consistency. How do you do this? I looked in Eclipse's Package Explorer and under Android 1.5android.jarandroidR.classRlayout and find R$layout.class. Do I copy the code out of there into my own class? From my very limited knowledge of Java, the following code doesn't make much sense: public static final class android.R$layout { // Field descriptor #8 I public static final int activity_list_item = 17367040; // Field descriptor #8 I public static final int browser_link_context_header = 17367054; // Field descriptor #8 I public static final int expandable_list_content = 17367041; // Field descriptor #8 I public static final int preference_category = 17367042; // Field descriptor #8 I public static final int select_dialog_item = 17367057; // Field descriptor #8 I public static final int select_dialog_multichoice = 17367059; // Field descriptor #8 I public static final int select_dialog_singlechoice = 17367058; // Field descriptor #8 I public static final int simple_dropdown_item_1line = 17367050; // Field descriptor #8 I public static final int simple_expandable_list_item_1 = 17367046; // Field descriptor #8 I public static final int simple_expandable_list_item_2 = 17367047; // Field descriptor #8 I public static final int simple_gallery_item = 17367051; // Field descriptor #8 I public static final int simple_list_item_1 = 17367043; // Field descriptor #8 I public static final int simple_list_item_2 = 17367044; // Field descriptor #8 I public static final int simple_list_item_checked = 17367045; // Field descriptor #8 I public static final int simple_list_item_multiple_choice = 17367056; // Field descriptor #8 I public static final int simple_list_item_single_choice = 17367055; // Field descriptor #8 I public static final int simple_spinner_dropdown_item = 17367049; // Field descriptor #8 I public static final int simple_spinner_item = 17367048; // Field descriptor #8 I public static final int test_list_item = 17367052; // Field descriptor #8 I public static final int two_line_list_item = 17367053; // Method descriptor #50 ()V // Stack: 3, Locals: 1 public R$layout(); 0 aload_0 [this] 1 invokespecial java.lang.Object() [1] 4 new java.lang.RuntimeException [2] 7 dup 8 ldc <String "Stub!"> [3] 10 invokespecial java.lang.RuntimeException(java.lang.String) [4] 13 athrow Line numbers: [pc: 0, line: 899] Local variable table: [pc: 0, pc: 14] local: this index: 0 type: android.R.layout Inner classes: [inner class info: #5 android/R$layout, outer class info: #64 android/R inner name: #55 layout, accessflags: 25 public static final] }

• PHP sessions and class members.

  - by JDW

  Ok, messing about with classes in PHP and can't get it to work the way I'm used to as a C++/Java-guy.

• Alternatives to CAT.NET for website security analysis

  - by Gavin Miller

  I'm looking for an alternative tool to CAT.NET for performing static security scans on .NET code. Currently the CAT.NET tooling/development is at a somewhat fragile stage and doesn't offer the reliability that I'm looking for. Are there any alternative static code analyzers that you use for detecting security issues?

• Given a trace of packets, how would you group them into flows?

  - by zxcvbnm

  I've tried it these ways so far: 1) Make a hash with the source IP/port and destination IP/port as keys. Each position in the hash is a list of packets. The hash is then saved in a file, with each flow separated by some special characters/line. Problem: Not enough memory for large traces. 2) Make a hash with the same key as above, but only keep in memory the file handles. Each packet is then put into the hash[key] that points to the right file. Problems: Too many flows/files (~200k) and it might run out of memory as well. 3) Hash the source IP/port and destination IP/port, then put the info inside a file. The difference between 2 and 3 is that here the files are opened and closed for each operation, so I don't have to worry about running out of memory because I opened too many at the same time. Problems: WAY too slow, same number of files as 2 so also impractical. 4) Make a hash of the source IP/port pairs and then iterate over the whole trace for each flow. Take the packets that are part of that flow and place them into the output file. Problem: Suppose I have a 60 MB trace that has 200k flows. This way, I would process, say, a 60 MB file 200k times. Maybe removing the packets as I iterate would make it not so painful, but so far I'm not sure this would be a good solution. 5) Split them by IP source/destination and then create a single file for each one, separating the flows by special characters. Still too many files (+50k). Right now I'm using Ruby to do it, which might've been a bad idea, I guess. Currently I've filtered the traces with tshark so that they only have relevant info, so I can't really make them any smaller. I thought about loading everything in memory as described in 1) using C#/Java/C++, but I was wondering if there wouldn't be a better approach here, especially since I might also run out of memory later on even with a more efficient language if I have to use larger traces. In summary, the problem I'm facing is that I either have too many files or that I run out of memory. I've also tried searching for some tool to filter the info, but I don't think there is one. The ones I've found only return some statistics and wouldn't scan for every flow as I need.

• Setup and configure tiny server to reply to any request

  - by alexeypro

  What's the best way to setup simple and tiny Web server (on port) which will reply to any request with static file; Target OS -- Mac OS X; Needs to be very light and (would be nice), if it would be configurable, so I can configure which requests which static files to serve. Thank you.

• overloading new/delete problem

  - by hidayat

  This is my scenario, Im trying to overload new and delete globally. I have written my allocator class in a file called allocator.h. And what I am trying to achieve is that if a file is including this header file, my version of new and delete should be used. So in a header file "allocator.h" i have declared the two functions extern void* operator new(std::size_t size); extern void operator delete(void *p, std::size_t size); I the same header file I have a class that does all the allocator stuff, class SmallObjAllocator { ... }; I want to call this class from the new and delete functions and I would like the class to be static, so I have done this: template<unsigned dummy> struct My_SmallObjectAllocatorImpl { static SmallObjAllocator myAlloc; }; template<unsigned dummy> SmallObjAllocator My_SmallObjectAllocatorImpl<dummy>::myAlloc(DEFAULT_CHUNK_SIZE, MAX_OBJ_SIZE); typedef My_SmallObjectAllocatorImpl<0> My_SmallObjectAllocator; and in the cpp file it looks like this: allocator.cc void* operator new(std::size_t size) { std::cout << "using my new" << std::endl; if(size > MAX_OBJ_SIZE) return malloc(size); else return My_SmallObjectAllocator::myAlloc.allocate(size); } void operator delete(void *p, std::size_t size) { if(size > MAX_OBJ_SIZE) free(p); else My_SmallObjectAllocator::myAlloc.deallocate(p, size); } The problem is when I try to call the constructor for the class SmallObjAllocator which is a static object. For some reason the compiler are calling my overloaded function new when initializing it. So it then tries to use My_SmallObjectAllocator::myAlloc.deallocate(p, size); which is not defined so the program crashes. So why are the compiler calling new when I define a static object? and how can I solve it?

• Making a Wrapper class for ActiveMQ

  - by DarthVader

  I want to make a Wrapper class for ActiveMQ which will have only send and get functions. I want to wrap them in a static class. Users can use this client and send, get messages to the activemq instance. I want this process to be transparent. There are two classes in this link My only handicap is, i need to this in c++ and not sure where to start. I havent used c++ for ages and now not sure how I can create this wrapper class. I m giving it a try as follows: // .h file #include <stdlib.h> #include <iostream> using namespace std; class ActiveMQWrapper { public: static void send(std::string message); static std::string get(); }; // .cpp file #include<string> #include<iostream> #include "ActiveMQWrapper.h" void ActiveMQWrapper::send(std::string message){ std::cout<<message; } std::string ActiveMQWrapper::get(){ return "test"; } // test file #include <string> #include <iostream> #include "ActiveMQWrapper.h" int main() { std::string foo ="test"; ActiveMQWrapper::send(foo); std::cout<<ActiveMQWrapper::get(); return 1; } When I added the following to .h file, hell breaks loose. Do you think I should seperate this impl to a factory and initialize and instance and return to the wrapper above? How do i deal with all the dependencies? private: Connection* connection; Session* session; Destination* destination; MessageProducer* producer; int numMessages; bool useTopic; bool sessionTransacted; std::string brokerURI; and the header files, i get several messages as errors, which complains about the path. How can i get this correct? I eventually want to build a Factory, get an instance and send or get the messages to the queue. is there a code sample i can look into to get this right? essential i want to use the functionality of only this producer and consumer. Edit: I understand there is no such thing as static class in C++ . This is my reference.

• What is the right way to process inconsistent data files?

  - by Tahabi

  I'm working at a company that uses Excel files to store product data, specifically, test results from products before they are shipped out. There are a few thousand spreadsheets with anywhere from 50-100 relevant data points per file. Over the years, the schema for the spreadsheets has changed significantly, but not unidirectionally - in the sense that, changes often get reverted and then re-added in the space of a few dozen to few hundred files. My project is to convert about 8000 of these spreadsheets into a database that can be queried. I'm using MongoDB to deal with the inconsistency in the data, and Python. My question is, what is the "right" or canonical way to deal with the huge variance in my source files? I've written a data structure which stores the data I want for the latest template, which will be the final template used going forward, but that only helps for a few hundred files historically. Brute-forcing a solution would mean writing similar data structures for each version/template - which means potentially writing hundreds of schemas with dozens of fields each. This seems very inefficient, especially when sometimes a change in the template is as little as moving a single line of data one row down or splitting what used to be one data field into two data fields. A slightly more elegant solution I have in mind would be writing schemas for all the variants I can find for pre-defined groups in the source files, and then writing a function to match a particular series of files with a series of variants that matches that set of files. This is because, more often that not, most of the file will remain consistent over a long period, only marred by one or two errant sections, but inside the period, which section is inconsistent, is inconsistent. For example, say a file has four sections with three data fields, which is represented by four Python dictionaries with three keys each. For files 7000-7250, sections 1-3 will be consistent, but section 4 will be shifted one row down. For files 7251-7500, 1-3 are consistent, section 4 is one row down, but a section five appears. For files 7501-7635, sections 1 and 3 will be consistent, but section 2 will have five data fields instead of three, section five disappears, and section 4 is still shifted down one row. For files 7636-7800, section 1 is consistent, section 4 gets shifted back up, section 2 returns to three cells, but section 3 is removed entirely. Files 7800-8000 have everything in order. The proposed function would take the file number and match it to a dictionary representing the data mappings for different variants of each section. For example, a section_four_variants dictionary might have two members, one for the shifted-down version, and one for the normal version, a section_two_variants might have three and five field members, etc. The script would then read the matchings, load the correct mapping, extract the data, and insert it into the database. Is this an accepted/right way to go about solving this problem? Should I structure things differently? I don't know what to search Google for either to see what other solutions might be, though I believe the problem lies in the domain of ETL processing. I also have no formal CS training aside from what I've taught myself over the years. If this is not the right forum for this question, please tell me where to move it, if at all. Any help is most appreciated. Thank you.
