• Is NUnit broken with Windows7 for C++/CLI?

  - by Andy Dent

  NUnit is failing in C++/CLI with a System.IO.FileNotFoundException. I have tried my own freshly-created project, the C++/CLI sample included with NUnit and the one from CodeProject How to use NUnit to test native C++ code using Visual Studio 2008sp1 with NUnit 2.5.5 as well as 2.4.8. I installed 2.4.8 just on C:\ in case there was something weird about paths with spaces such as Program Files (x86). I have no problems with a C# sample using NUnit. in NUnit GUI, all of these C++/CLI projects encounter the same problem, on attempting to open the projects. I'd really like to use NUnit but for now have had to go back to standard Microsoft tests System.IO.FileNotFoundException...

• empty response body in ajax (or 206 Partial Content)

  - by Nikita Rybak

  Hi guys, I'm feeling completely stupid because I've spent two hours solving task which should be very simple and which I solved many times before. But now I'm not even sure in which direction to dig. I fail to fetch static content using ajax from local servers (Apache and Mongrel). I get responses 200 and 206 (depending on the server), empty response text (although Content-Length header is always correct), firebug shows request in red. Javascript is very generic, I'm getting same results even here: http://www.w3schools.com/ajax/tryit.asp?filename=tryajax_first (just change document location to 'http://localhost:3000/whatever') So, it's probably not the cause. Well, now I'm out of ideas. I can also post http headers, if it'll help. Thanks!

• Why are my installed fonts not available in .NET?

  - by Dan Herbert

  I'm trying to render some images with text using a font I just added to my machine and no matter what I do, I can't seem to get the font to become accessible in .NET. I tried using PrivateFontCollection.AddFontFile(filename) and PrivateFontCollection.AddMemoryFont(...) to load the font into memory. Whenever I do this, the method throws a "File Not Found" exception, which is unusual because I get this exception when loading the font from memory, where there should be no files to be "not found". Initially, I thought it may be because the font I was trying to use was in the .pfm format, so I converted the font to .otf and had the same problem. Then I tried installing the .otf font to my Windows Fonts folder so I could pull it from FontFamily.Families. Once I installed the font, it became available in Microsoft Word & Notepad2. However, when I try to load it from FontFamily.Families, it is not included in the array. I thought rebooting my machine would fix the issue but obviously there is something more complicated involved here. Is there something basic I just might have missed when installing the font in my machine (Windows Vista), or is there another way to programmatically load a font that I should be using instead? Is .otf not supported in .NET?

• 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(); } `

• Regarding: PKCS7, X509 and DER

  - by Sid

  Hi, I am novice to the "World of cryptography". I started working with OPENSSL. I need some information and basically I do have some doubts. I have a DER format file. I read the file using following command, "openssl x509 -inform DER -in filename.der -text" I got what I supposed to be. Following things I wanted to know: 1. What is the difference between PKCS7, DER and X509 ? (My understanding is, DER is format, X509 is certificate, and PKCS7 is the standard) I wrote a test file which accepts the DER file and outputs the version, serial number, Subject, Validity date before and Validity date after, But I am unable to get certificate verified. Following is the API Used. int i = X509_verify(X509 *x509 , X509_get_pubkey(X509 *x509)); But 'i' value is 'i' < 0(zero) This is why I am getting "Signature verification problems". How to overcome this? In My test file I am unable to read the "Signature Algorithm", "Subject Public Key Info", "X509v3 extensions" and "-----BEGIN CERTIFICATE-----" to "-----END CERTIFICATE-----" Please give some inputs. Thanks in Advance. openSid

• C# Application Calling Powershell Script Issues

  - by Ben

  Hi, I have a C# Winforms application which is calling a simple powershell script using the following method: Process process = new Process(); process.StartInfo.FileName = @"powershell.exe"; process.StartInfo.Arguments = String.Format("-noexit \"C:\Develop\{1}\"", scriptName); process.Start(); The powershell script simply reads a registry key and outputs the subkeys. $items = get-childitem -literalPath hklm:\software foreach($item in $items) { Write-Host $item } The problem I have is that when I run the script from the C# application I get one set of results, but when I run the script standalone (from the powershell command line) I get a different set of results entirely. The results from running from the c# app are: HKEY_LOCAL_MACHINE\software\Adobe HKEY_LOCAL_MACHINE\software\Business Objects HKEY_LOCAL_MACHINE\software\Helios HKEY_LOCAL_MACHINE\software\InstallShield HKEY_LOCAL_MACHINE\software\Macrovision HKEY_LOCAL_MACHINE\software\Microsoft HKEY_LOCAL_MACHINE\software\MozillaPlugins HKEY_LOCAL_MACHINE\software\ODBC HKEY_LOCAL_MACHINE\software\Classes HKEY_LOCAL_MACHINE\software\Clients HKEY_LOCAL_MACHINE\software\Policies HKEY_LOCAL_MACHINE\software\RegisteredApplications PS C:\Develop\RnD\SiriusPatcher\Sirius.Patcher.UI\bin\Debug When run from the powershell command line I get: PS M: C:\Develop\RegistryAccess.ps1 HKEY_LOCAL_MACHINE\software\ATI Technologies HKEY_LOCAL_MACHINE\software\Classes HKEY_LOCAL_MACHINE\software\Clients HKEY_LOCAL_MACHINE\software\Equiniti HKEY_LOCAL_MACHINE\software\Microsoft HKEY_LOCAL_MACHINE\software\ODBC HKEY_LOCAL_MACHINE\software\Policies HKEY_LOCAL_MACHINE\software\RegisteredApplications HKEY_LOCAL_MACHINE\software\Wow6432Node PS M: The second set of results match what I have in the registry, but the first set of results (which came from the c# app) don't. Any help or pointers would be greatly apreciated :) Ben

• Paperclip and Amazon S3 Issue

  - by Jimmy

  Hey everyone, I have a rails app running on Heroku. I am using paperclip for some simple image uploads for user avatars and some other things, I have S3 set as my backend and everything seems to be working fine except when trying to push to S3 I get the following error: The AWS Access Key Id you provided does not exist in our records. Thinking I mis-pasted my access key and secret key, I tried again, still no luck. Thinking maybe it was just a buggy key I deactivated it and generated a new one. Still no luck. Now for both keys I have used the S3 browser app on OS X and have been able to connect to each and view my current buckets and add/delete buckets. Is there something I should be looking out for? I have my application's S3 and paperclip setup like so development: bucket: (unique name) access_key_id: ENV['S3_KEY'] secret_access_key: ENV['S3_SECRET'] test: bucket: (unique name) access_key_id: ENV['S3_KEY'] secret_access_key: ENV['S3_SECRET'] production: bucket: (unique_name) access_key_id: ENV['S3_KEY'] secret_access_key: ENV['S3_SECRET'] has_attached_file :cover, :styles => { :thumb => "50x50" }, :storage => :s3, :s3_credentials => "#{RAILS_ROOT}/config/s3.yml", :path => ":class/:id/:style/:filename" Note: I just added the (unique name) bits, those aren't actually there--I have also verified bucket names, but I don't even think this is getting that far. I also have my heroku environment vars setup correctly and have them setup on dev

• How to read Unicode characters from command-line arguments in Python on Windows

  - by Craig McQueen

  I want my Python script to be able to read Unicode command line arguments in Windows. But it appears that sys.argv is a string encoded in some local encoding, rather than Unicode. How can I read the command line in full Unicode? Example code: argv.py import sys first_arg = sys.argv[1] print first_arg print type(first_arg) print first_arg.encode("hex") print open(first_arg) On my PC set up for Japanese code page, I get: C:\temp>argv.py "PC·??????08.09.24.doc" PC·??????08.09.24.doc <type 'str'> 50438145835c83748367905c90bf8f9130382e30392e32342e646f63 <open file 'PC·??????08.09.24.doc', mode 'r' at 0x00917D90> That's Shift-JIS encoded I believe, and it "works" for that filename. But it breaks for filenames with characters that aren't in the Shift-JIS character set—the final "open" call fails: C:\temp>argv.py Jörgen.txt Jorgen.txt <type 'str'> 4a6f7267656e2e747874 Traceback (most recent call last): File "C:\temp\argv.py", line 7, in <module> print open(first_arg) IOError: [Errno 2] No such file or directory: 'Jorgen.txt' Note—I'm talking about Python 2.x, not Python 3.0. I've found that Python 3.0 gives sys.argv as proper Unicode. But it's a bit early yet to transition to Python 3.0 (due to lack of 3rd party library support). Update: A few answers have said I should decode according to whatever the sys.argv is encoded in. The problem with that is that it's not full Unicode, so some characters are not representable. Here's the use case that gives me grief: I have enabled drag-and-drop of files onto .py files in Windows Explorer. I have file names with all sorts of characters, including some not in the system default code page. My Python script doesn't get the right Unicode filenames passed to it via sys.argv in all cases, when the characters aren't representable in the current code page encoding. There is certainly some Windows API to read the command line with full Unicode (and Python 3.0 does it). I assume the Python 2.x interpreter is not using it.

• SMO restore of SQL database doesn't overwrite

  - by Tom H.

  I'm trying to restore a database from a backup file using SMO. If the database does not already exist then it works fine. However, if the database already exists then I get no errors, but the database is not overwritten. The "restore" process still takes just as long, so it looks like it's working and doing a restore, but in the end the database has not changed. I'm doing this in Powershell using SMO. The code is a bit long, but I've included it below. You'll notice that I do set $restore.ReplaceDatabase = $true. Also, I use a try-catch block and report on any errors (I hope), but none are returned. Any obvious mistakes? Is it possible that I'm not reporting some error and it's being hidden from me? Thanks for any help or advice that you can give! function Invoke-SqlRestore { param( [string]$backup_file_name, [string]$server_name, [string]$database_name, [switch]$norecovery=$false ) # Get a new connection to the server [Microsoft.SqlServer.Management.Smo.Server]$server = New-SMOconnection -server_name $server_name Write-Host "Starting restore to $database_name on $server_name."

• RMagic Error in rails, with AM Charts

  - by Elliot

  Hi Everyone, I'm using AMCharts and rails. AMCharts uses the Image Magic lib to export an image of the chart. In rails this is done with the gem, RMagic. In a controller this is implemented with the following controller method: def export width = params[:width].to_i height = params[:height].to_i data = {} img = Magick::Image.new(width, height) height.times do |y| row = params["r#{y}"].split(',') row.size.times do |r| pixel = row[r].to_s.split(':') pixel[0] = pixel[0].to_s.rjust(6, '0') if pixel.size == 2 pixel[1].to_i.times do (data[y] ||= []) << pixel[0] end else (data[y] ||= []) << pixel[0] end end width.times do |x| img.pixel_color(x, y, "##{data[y][x]}") end end img.format = "PNG" send_data(img.to_blob , :disposition => 'inline', :type => 'image/png', :filename => "chart.png?#{rand(99999999).to_i}") end When the controller is accessed however, I receive this error in the page: The change you wanted was rejected. Maybe you tried to change something you didn't have access to. And this error in the logs (its running on heroku btw): ActionController::InvalidAuthenticityToken (ActionController::InvalidAuthenticityToken): /home/heroku_rack/lib/static_assets.rb:9:in `call' /home/heroku_rack/lib/last_access.rb:25:in `call' /home/heroku_rack/lib/date_header.rb:14:in `call' thin (1.0.1) lib/thin/connection.rb:80:in `pre_process' thin (1.0.1) lib/thin/connection.rb:78:in `catch' thin (1.0.1) lib/thin/connection.rb:78:in `pre_process' thin (1.0.1) lib/thin/connection.rb:57:in `process' thin (1.0.1) lib/thin/connection.rb:42:in `receive_data' eventmachine (0.12.6) lib/eventmachine.rb:240:in `run_machine' eventmachine (0.12.6) lib/eventmachine.rb:240:in `run' thin (1.0.1) lib/thin/backends/base.rb:57:in `start' thin (1.0.1) lib/thin/server.rb:150:in `start' thin (1.0.1) lib/thin/controllers/controller.rb:80:in `start' thin (1.0.1) lib/thin/runner.rb:173:in `send' thin (1.0.1) lib/thin/runner.rb:173:in `run_command' thin (1.0.1) lib/thin/runner.rb:139:in `run!' thin (1.0.1) bin/thin:6 /usr/local/bin/thin:20:in `load' /usr/local/bin/thin:20 Rendering /disk1/home/slugs/149903_609c236_eb4f/mnt/public/422.html (422 Unprocessable Entity) Anyone have any idea what's going on here?

• Writing files in App_Data causes tempdata to be null

  - by RAMX

  I have a small asp.net MVC 1 web app that can store files and create directories in the App_Data directory. When the write operation succeeds, I add a message to the tempdata and do a redirectToRoute. The problem is that the tempdata is null when the action is executed. If i write the files in a directory outside of the web applications root directory, the tempdata is not null and everything works correctly. Any ideas why writing in the app_data seems to clear the tempdata ? edit: if DRS.Logic.Repository.Manager.CreateFile(path, hpf, comment) writes in the App_Data, TempData will be null in the action being redirected to. if it is a directory out of the web app root it is fine. No exceptions are being thrown. [AcceptVerbs(HttpVerbs.Post)] public ActionResult Create(int id, string path, FormCollection form) { ViewData["path"] = path; ViewData["id"] = id; HttpPostedFileBase hpf; string comment = form["FileComment"]; hpf = Request.Files["File"] as HttpPostedFileBase; if (hpf.ContentLength != 0) { DRS.Logic.Repository.Manager.CreateFile(path, hpf, comment); TempData["notification"] = "file was created"; return RedirectToRoute(new { controller = "File", action ="ViewDetails", id = id, path = path + Path.GetFileName(hpf.FileName) }); } else { TempData["notification"] = "No file were selected."; return View(); } }

• VB.NET error: Microsoft.ACE.OLEDB.12.0 provider is not registered [RESOLVED]

  - by Azim

  I have a Visual Studio 2008 solution with two projects (a Word-Template project and a VB.Net console application for testing). Both projects reference a database project which opens a connection to an MS-Access 2007 database file and have references to System.Data.OleDb. In the database project I have a function which retrieves a data table as follows private class AdminDatabase ' stores the connection string which is set in the New() method dim strAdminConnection as string public sub New() ... adminName = dlgopen.FileName conAdminDB = New OleDbConnection conAdminDB.ConnectionString = "Data Source='" + adminName + "';" + _ "Provider=Microsoft.ACE.OLEDB.12.0" ' store the connection string in strAdminConnection strAdminConnection = conAdminDB.ConnectionString.ToString() My.Settings.SetUserOverride("AdminConnectionString", strAdminConnection) ... End Sub ' retrieves data from the database Public Function getDataTable(ByVal sqlStatement As String) As DataTable Dim ds As New DataSet Dim dt As New DataTable Dim da As New OleDbDataAdapter Dim localCon As New OleDbConnection localCon.ConnectionString = strAdminConnection Using localCon Dim command As OleDbCommand = localCon.CreateCommand() command.CommandText = sqlStatement localCon.Open() da.SelectCommand = command da.Fill(dt) getDataTable = dt End Using End Function End Class When I call this function from my Word 2007 Template project everything works fine; no errors. But when I run it from the console application it throws the following exception ex = {"The 'Microsoft.ACE.OLEDB.12.0' provider is not registered on the local machine."} Both projects have the same reference and the console application did work when I first wrote it (a while ago) but now it has stopped work. I must be missing something but I don't know what. Any ideas? Thanks Azim

• BreezingForms Integrator Finalize Code and $this->execPieceByName('ff_InitLib');

  - by nickyt

  I've started working on a Joomla! project (I'm mainly a C#/ASP.NET kind a guy). I'm using BreezingForms and have created forms, got them working, but now I need to do some additional code in the "Finalize Code" section. I need to access form elements via BreezingForms(FacileForms) API. Here's what I'm doing, but it chokes: $this->execPieceByName('ff_SubmitLib'); // Is this necessary? // load the standard Facile Forms library $this->execPieceByName('ff_InitLib'); // page breaks here. // get the name of the uploaded file $filename = ff_getSubmit('someUploadedFile'); Now I don't know what goes wrong. The page posts back blank. I'm not sure how to debug this in Joomla. I currently do not have access to the server to debug, so I would need to debug remotely at runtime (not ideal I know). My account is of type Administrator for the Joomla backend. As far as I know all the plugins/modules are installed. Any ideas?

• Indy IdSMTP and attachments in Thunderbird

  - by Lobuno

  Hello! Using the latest snapshot of Indy tiburon on D2010. A very simple project like: var stream: TFileStream; (s is TidSMTP and m is TidMessage) begin s.Connect; Stream := TFileStream.Create('c:\Test.zip', fmOpenRead or fmShareExclusive); try with TIdAttachmentMemory.Create(m.MessageParts, Stream) do begin ContentType := 'application/x-zip-compressed'; Name := ExtractFilePath('C:\'); //' FileName := 'Test.zip'; end; finally FreeAndNil(Stream); end; s.Send(m); s.Disconnect(); end; Everything works Ok in Outlook, The bat!, OE, yahoo, etc... but in Thunderbird the attachment is not shown. Looking at the source of the message in Thunderbird, the attachment is there. The only difference I can find between messages send by indy and other clients is that Indy messages have this order: Content-Type: multipart/mixed; boundary="Z\=_7oeC98yIhktvxiwiDTVyhv9R9gwkwT1" MIME-Version: 1.0 while any other clients have the order: MIME-Version: 1.0 Content-Type: multipart/mixed; boundary="Z\=_7oeC98yIhktvxiwiDTVyhv9R9gwkwT1" Don't know if THAT is the source of the problem, but if so: is this a bug on Thunderbird or is this a problem with indy which "malforms" the headers of the messages? Is this order a problem? Does that matter anyway?

• Android media thumbnails. Serious issues?

  - by Ralphleon

  I've been playing with android's thumbnails for a while now, and I've seen some inconsistencies that make me want to scream. My goal is to have a simple list of all Images (and a separate list for video) with the thumbnail and filename. Device: HTC Evo (fresh from Google I/o) First off: http://androidsamples.blogspot.com/2009/06/how-to-display-thumbnails-of-images.html That code doesn't seem to work at all, thumbnails are duplicated... some with the "mirror" effect and some without. Also some won't load and just display a black square. I've tried rebuilding the thumbnails by deleting the "alblum thumbs" directory from the SD card. HTC's gallery application seem to show everything fine. This approach seems to work: Bitmap thumb = MediaStore.Images.Thumbnails.getThumbnail( getContentResolver(), id, MediaStore.Video.Thumbnails.MICRO_KIND, null); imageView.setImageBitmap(curThumb); where id is the original images id and imageView is some image view. This is great! But, strangely, way too slow to be used inside a SimpleViewBinder. Next approach: String [] proj = {MediaStore.Images.Thumbnails._ID}; Cursor c = managedQuery(MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI, proj, MediaStore.Images.Thumbnails.IMAGE_ID + "=" +id , null, null); if (c != null && c.moveToFirst()) { Uri thumb = Uri.withAppendedPath(mThumbUri,c.getLong(0)+""); imageView.setImageURI(thumb); } I should explain that I feel the needed WHERE condition is required because there doesn't seem to be any guarantee that your uri will have the same ID for both a thumbnail and its parent image. This works for all of the current images, but as soon as I start adding pictures with the camera they show up as blank! Debugging shows a dreaded: SkImageDecoder::Factory returned null error and the URI is returned as invalid. These are the same images that work with the previous call. Can anyone either catch my logical failure or point me to some working code?

• Office Word 2007 Interop - Header FieldCodes not showing up in my code, but are when viewed with Wor

  - by Ryan

  Hello, I'm writing an application in Delphi (have two over revisions of it written in both C# and Visual Basic, also). In my C# and Visual Basic version, I did something like the following to loop through the header/footer FieldCodes: // Supress filename, date and username field codes in headers fieldCount = WordApp.ActiveDocument.Sections[1].Headers[Microsoft.Office.Interop.Word.WdHeaderFooterIndex.wdHeaderFooterPrimary].Range.Fields.Count; for (Int32 x = 1; x <= fieldCount; x++) { if ((WordApp.ActiveDocument.Sections[1].Headers[Microsoft.Office.Interop.Word.WdHeaderFooterIndex.wdHeaderFooterPrimary].Range.Fields[x].Type == Microsoft.Office.Interop.Word.WdFieldType.wdFieldDate) || (WordApp.ActiveDocument.Sections[1].Headers[Microsoft.Office.Interop.Word.WdHeaderFooterIndex.wdHeaderFooterPrimary].Range.Fields[x].Type == Microsoft.Office.Interop.Word.WdFieldType.wdFieldFileName) || (WordApp.ActiveDocument.Sections[1].Headers[Microsoft.Office.Interop.Word.WdHeaderFooterIndex.wdHeaderFooterPrimary].Range.Fields[x].Type == Microsoft.Office.Interop.Word.WdFieldType.wdFieldUserName)) { WordApp.ActiveDocument.Sections[1].Headers[Microsoft.Office.Interop.Word.WdHeaderFooterIndex.wdHeaderFooterPrimary].Range.Fields[x].Select(); WordApp.Selection.TypeText("{ " + WordApp.ActiveDocument.Sections[1].Headers[Microsoft.Office.Interop.Word.WdHeaderFooterIndex.wdHeaderFooterPrimary].Range.Fields[x].Code.Text + " }"); } } In my Delphi one I'm doing the same kind of routine. But, I've got a Word file that I'm trying to process and it has a Date FieldCode in the Header. My code is not finding the field code for some odd reason. It says there's no Fields in the Header. Does anyone know if there's such thing as like hidden FieldCodes, or something that would cause these to not show up in my code? Thanks, Ryan
