  • Microsoft.Build.Engine Error (default targets): Target GetFrameworkPaths: Could not locate the .NET

    - by Mitchan Adams
    I am writing a webservice, that when called should build a C# project. I'm using the framework 2 reference, Microsoft.Buld.Engine and Microsoft.Build.Framework. If you look under the '<Import>' section .csproj file, by default it has: <Import Project="$(MSBuildToolsPath)\Microsoft.CSharp.targets" /> which I then changed to: <Import Project="$(MSBuildBinPath)\Microsoft.CSharp.targets" /> My code to build the csproj is: Engine buildEngine = new Engine(Path.Combine(Environment.GetEnvironmentVariable("SystemRoot"), @"Microsoft.NET\Framework\v2.0.50727")); FileLogger logger = new FileLogger(); logger.Parameters = @"logfile=c:\temp\build.log"; buildEngine.RegisterLogger(logger); bool success = buildEngine.BuildProjectFile([Path_Of_Directory]+ "ProjectName.csproj"); buildEngine.UnregisterAllLoggers(); The success variable returns a false because the build faild. I then check the build.log file and this is the error I recieve: *Build started 3/17/2010 11:16:56 AM. ______________________________ Project "[Path_Of_Directory]\ProjectName.csproj" (default targets): Target GetFrameworkPaths: Could not locate the .NET Framework SDK.

  • How do I compress a Json result from ASP.NET MVC with IIS 7.5

    - by Gareth Saul
    I'm having difficulty making IIS 7 correctly compress a Json result from ASP.NET MVC. I've enabled static and dynamic compression in IIS. I can verify with Fiddler that normal text/html and similar records are compressed. Viewing the request, the accept-encoding gzip header is present. The response has the mimetype "application/json", but is not compressed. I've identified that the issue appears to relate to the MimeType. When I include mimeType="*/*", I can see that the response is correctly gzipped. How can I get IIS to compress WITHOUT using a wildcard mimeType? I assume that this issue has something to do with the way that ASP.NET MVC generates content type headers. The CPU usage is well below the dynamic throttling threshold. When I examine the trace logs from IIS, I can see that it fails to compress due to not finding a matching mime type. <httpCompression directory="%SystemDrive%\inetpub\temp\IIS Temporary Compressed Files" noCompressionForProxies="false"> <scheme name="gzip" dll="%Windir%\system32\inetsrv\gzip.dll" /> <dynamicTypes> <add mimeType="text/*" enabled="true" /> <add mimeType="message/*" enabled="true" /> <add mimeType="application/x-javascript" enabled="true" /> <add mimeType="application/json" enabled="true" /> </dynamicTypes> <staticTypes> <add mimeType="text/*" enabled="true" /> <add mimeType="message/*" enabled="true" /> <add mimeType="application/x-javascript" enabled="true" /> <add mimeType="application/atom+xml" enabled="true" /> <add mimeType="application/xaml+xml" enabled="true" /> <add mimeType="application/json" enabled="true" /> </staticTypes> </httpCompression>

  • ASP.NET Chart Control errors in Event Viewer

    - by Richard Reddy
    Hi, I have been using the ASP.NET chart controls for a while on win2k3 (32bit) setups without any issue but have noticed that on our new win2k8 (64bit) box I am getting a warning message showing up in the event viewer from the chart control. In my web.config file I have the following tag telling the Chart Control where I can store the Temp Files: <add key="ChartImageHandler" value="storage=file;timeout=20;dir=c:\TempImageFiles\;" /> Below is the warning message produced by the control: Event code: 3005 Event message: An unhandled exception has occurred.

  • C# winforms: graphics.DrawImage problem

    - by Tony
    Hi, I have a really strange problem with Graphics.DrawImage method. I have the PictureBox control in the Panel control with AllowScroll property = true. The program cuts the image on small parts basing on the area selected by the user. I load the image 300x547 and select the area (the red rectangle): program properly cuts the image: then, I load another image 427x640: and then, as the result I see that the image is not cut properly. Each img.jpg file has properly width & height but the drawn image is too small: here's the code snippet - it saves the bitmap area selected by the user: Bitmap bmp = new Bitmap(selectedAreaRECT.Width, selectedAreaRECT.Height); Graphics g = Graphics.FromImage(bmp); g.DrawImage(OriginalIMG, 0,0, selectedAreaRECT, GraphicsUnit.Pixel); g.Save(); g.Dispose(); bmp.Save(AppDomain.CurrentDomain.BaseDirectory + @"\Temp\" + "img1.jpg", System.Drawing.Imaging.ImageFormat.Jpeg); As You see, the code is the same for the img1.jpg from image A and from Image B. I'm trying to resolve that stupid problem for too long, I don't know what's the reason of that problem. I tried diffrent constructors of the DrawImage method, with no success

  • batch file to merge .js files from subfolders into one combined file

    - by Andrew Johns
    I'm struggling to get this to work. Plenty of examples on the web, but they all do something just slightly different to what I'm aiming to do, and every time I think I can solve it, I get hit by an error that means nothing to me. After giving up on the JSLint.VS plugin, I'm attempting to create a batch file that I can call from a Visual Studio build event, or perhaps from cruise control, which will generate JSLint warnings for a project. The final goal is to get a combined js file that I can pass to jslint, using: cscript jslint.js < tmp.js which would validate that my scripts are ready to be combined into one file for use in a js minifier, or output a bunch of errors using standard output. but the js files that would make up tmp.js are likely to be in multiple subfolders in the project, e.g: D:\_projects\trunk\web\projectname\js\somefile.debug.js D:\_projects\trunk\web\projectname\js\jquery\plugins\jquery.plugin.js The ideal solution would be to be able to call a batch file along the lines of: jslint.bat %ProjectPath% and this would then combine all the js files within the project into one temp js file. This way I would have flexibility in which project was being passed to the batch file. I've been trying to make this work with copy, xcopy, type, and echo, and using a for do loop, with dir /s etc, to make it do what I want, but whatever I try I get an error.

  • Keymap issues with NX from Mac OS X Lion

    - by Andy
    I tried to answer the question from Mark: Keymap issues with NX from Mac OS X Lion to Ubuntu However, it is locked so I figured I would post a new question / answer. I have been trying to answer this for a few days now because I have no issues when connecting through NX Client (technically OpenNX) to FreeNX server from an iMac (with Lion), but if I try to connect with a Macbook Pro I get horrible keyboard binding issues. The fix that is working for me is to go into: ~/.nx/config/HOST.nxs and change: <option key="Current keyboard" value="false"/> <option key="Custom keyboard layout" value="empty"/> <option key="Grab keyboard" value="false"/> I have tried this on three NX Servers and all are fixed. Hope it helps or gets you closer. Always check in the ~/.nx/temp/ for the sshlog and see if --keyboard="empty/empty" instead of "pc105/en" because the Mac is really pc104. 9:05:35: startsession --session="HOST" --type="unix-gnome" --cache="8M" --images="32M" --link="adsl" --geometry="2556\ x1396" --screeninfo="2560x1440x32+render" --keyboard="empty/empty" --backingstore="1" --encryption="1" --composite="1" --\ shmem="1" --shpix="1" --streaming="1" --samba="0" --cups="0" --nodelay="1" --defer="0" --client="macosx" --media="0" --st\ rict="0" --aux="1"

  • Figuring out the performance limitation of an ADC on a PIC microcontroller

    - by AKE
    I'm spec-ing the suitability of a microcontroller like PIC for an analog-to-digital application. This would be preferable to using external A/D chips. To do that, I've had to run through some computations, pulling the relevant parameters from the datasheets. I'm not sure I've got it right -- would appreciate a check! Here's the simplest example: PIC10F220 is the simplest possible PIC with an ADC. Runs at clock speed of 8MHz. Has an instruction cycle of 0.5us (4 clock steps per instruction) So: Taking Tacq = 6.06 us (acquisition time for ADC, assume chip temp. = 50*C) [datasheet p34] Taking Fosc = 8MHz (? clock speed) Taking divisor = 4 (4 clock steps per CPU instruction) This gives TAD = 0.5us (TAD = 1/(Fosc/divisor) ) Conversion time is 13*TAD [datasheet p31] This gives conversion time 6.5us ADC duration is then 12.56 us [? Tacq + 13*TAD] Assuming at least 2 instructions for load/store: This is another 1 us [0.5 us per instruction] Which would give max sampling rate of 73.7 ksps (1/13.56) Supposing 8 more instructions for real-time processing: This is another 4 us Thus, total ADC/handling time = 17.56us (12.56us + 1us + 4us) So expected upper sampling rate is 56.9 ksps. Nyquist frequency for this sampling rate is therefore 28 kHz. If this is right, it suggests the (theoretical) performance suitability of this chip's A/D is for signals that are bandlimited to 28 kHz. Is this a correct interpretation of the information given in the data sheet? Any pointers would be much appreciated! AKE

  • AjaxControlToolkit Resource Files Not Copied To Output in MSBuild Script

    - by Dario Solera
    I'm new to MSBuild, but I managed to setup the following simple script: <Project ToolsVersion="3.5" DefaultTargets="Compile" xmlns="http://schemas.microsoft.com/developer/msbuild/2003"> <PropertyGroup> <Configuration Condition="'$(Configuration)' == ''">Debug</Configuration> </PropertyGroup> <ItemGroup> <SolutionRoot Include=".." /> <BuildArtifacts Include=".\Artifacts\" /> <SolutionFile Include="..\SolutionName.sln" /> </ItemGroup> <Target Name="Clean"> <RemoveDir Directories="@(BuildArtifacts)" /> </Target> <Target Name="Init" DependsOnTargets="Clean"> <MakeDir Directories="@(BuildArtifacts)" /> </Target> <Target Name="Compile" DependsOnTargets="Init"> <MSBuild Projects="@(SolutionFile)" Properties="OutDir=%(BuildArtifacts.FullPath);Configuration=$(Configuration)" /> <MakeDir Directories="%(BuildArtifacts.FullPath)\_PublishedWebsites\RDE.XAP.UnifiedGui.Web\Temp" /> </Target> </Project> The solution has 23 projects, 4 of which are WebApps. Now, the script works fine and the output is generated correctly. The only problem I counter is with two WebApp projects in the solution that use the AJAX Control Toolkit. The toolkit has a set of folders (e.g. ar, it, es, fr) that contain localized resources. These folders are not copied in the bin directory of the WebApps when the solution is built in MSBuild, but they are copied when it is built in Visual Studio. How can I solve this in a clean manner? I know I could write a (quite convoluted) task that copies the directories after the compile, but it does not seem the right solution to me. Also, neither Google, SO and MSDN could provide more details on this kind of issue.

  • Dynamically manipulate php cookies with javascript/jquery

    - by pundit
    Hi guys, I'm currently building a dynamic menu bar(vertical and horizontal). in the default position its vertical. the user have the option to show the horizontal position and hide and vertical. I am currently doing that with javascript/ jquery. in order to keep the menu bar in the horizontal position i am keeping a count with a cookie. the problem is that when i use the click function in javascript i want to change the value of the cookie. i have no knowledge of how to do this. Can anyone assist me with this. all help would be appreciated. <?php setcookie('menu', 1, time()+(86400)); ?> $(document).ready(function() { $('#temp').hide(); if(<?php echo $_COOKIE['menu'];?> == 1){ $('#topmenu').hide(); $('#sidemenu').floating().dropShadow().floating(); $('#sidemenu_bottom').hide(); }else{ $('#topmenu').show(); $('#topmenu').dropShadow(); $('#sidemenu').hide(); $('#sidemenu').removeShadow(); } $('#move').click(function(){ $('#sidemenu').hide("drop",{},2000); $('#sidemenu').removeShadow(); $('#topmenu').show(); $('#topmenu').dropShadow(); $('#sidemenu_bottom').show(); $('#sidemenu_bottom').floating().dropShadow().floating(); }); }); This is what i have so far and the default cookie is working as well as the javascript. its just to change the cookie value now. thanks.

  • Inserting "null" (literally) in to a stored procedure parameter.

    - by Nazadus
    I'm trying to insert the word "Null" (literally) in to a parameter for a stored procedure. For some reason SqlServer seems to think I mean NULL and not "Null". If I do a check for IF @LastName IS NULL // Test: Do stuff Then it bypasses that because the parameter isn't null. But when I do: INSERT INTO Person (<params>) VALUES (<stuff here>, @LastName, <more stuff here>); // LastName is 'Null' It bombs out saying that LastName doesn't accept nulls. I would seriously hate to have this last name, but someone does... and it's bombing the application. We're using SubSonic 2.0 (yeah, it's fairly old but upgrading is painful) as our DAL and stepping through it, I see it does create the parameters properly (for what I can tell). I've tried creating a temp table to see if I could replicate it manually but it seems to work just fine. Here is the example I create: DECLARE @myval VARCHAR(50) SET @myval = 'Null' CREATE TABLE #mytable( name VARCHAR(50)) INSERT INTO #mytable VALUES (@myval) SELECT * FROM #mytable DROP table #mytable Any thoughts on how I can fix this?

  • Usage of putty in command line from Hudson

    - by kij
    Hi, I'm trying to use putty in command line from an hudson job. The command is the following one: putty -ssh -2 -P 22 USERNAME@SERVER_ADDR -pw PASS -m command.txt Where 'command.txt' is a shell script to execute in the server through SSH. If i launch this command from the Window command prompt, it works, the shell script is executed on the server machine. If i launch a build of the hudson job configured with this batch command, it doesn't work. The build is running... and running... and running.. without doing anything, and i have to stop it manually. So my question is: Is it possible to launch an external programm (i.e. putty) from an hudson job ? ps: i tried SSH plugin but... not a really good plugin (pre/post build, fail status of the commands launched not caught by hudson, etc.) Thanks in advance for your help. Best regards. kij EDIT: These are the build logs: [workspace] $ cmd /c call C:\WINDOWS\TEMP\hudson7429256014041663539.bat C:\Hudson\jobs\Artifact deployer\workspace>putty -ssh -2 -P 22 USER@SERV_ADD -pw PASS -m com.txt Le build a été annulé Finished: ABORTED And the Hudson.err.log file at the same time (after a stop): 3 juin 2010 18:27:28 hudson.model.Run run INFO: Artifact deployer #6 aborted java.lang.InterruptedException at java.lang.ProcessImpl.waitFor(Native Method) at hudson.Proc$LocalProc.join(Proc.java:179) at hudson.Launcher$ProcStarter.join(Launcher.java:278) at hudson.tasks.CommandInterpreter.perform(CommandInterpreter.java:83) at hudson.tasks.CommandInterpreter.perform(CommandInterpreter.java:58) at hudson.tasks.BuildStepMonitor$1.perform(BuildStepMonitor.java:19) at hudson.model.AbstractBuild$AbstractRunner.perform(AbstractBuild.java:601) at hudson.model.Build$RunnerImpl.build(Build.java:174) at hudson.model.Build$RunnerImpl.doRun(Build.java:138) at hudson.model.AbstractBuild$AbstractRunner.run(AbstractBuild.java:416) at hudson.model.Run.run(Run.java:1241) at hudson.model.FreeStyleBuild.run(FreeStyleBuild.java:46) at hudson.model.ResourceController.execute(ResourceController.java:88) at hudson.model.Executor.run(Executor.java:124) My shell script only write "hello" in a "hello.txt" file on the server, and nothing is done.

  • Zend file upload error

    - by jgnasser
    I am attempting to upload a file using Zend Framework 1.8 and I get some errors. Here is the code snippet: The form element: $element = new Zend_Form_Element_File('doc'); $element->setLabel('Upload an image:') ->setDestination('/path/to/my/upload/folder'); $element->addValidator('Count', false, 1); $element->addValidator('Size', false, 102400); $element->addValidator('Extension', false, 'jpg,png,gif,doc,docx,xls,xlsx,txt'); $this->addElement($element); The code for handling the upload: $adapter = new Zend_File_Transfer_Adapter_Http(); if (!$adapter->receive()) { $messages = $adapter->getMessages(); echo implode("\n", $messages); } This works fine and the file is uploaded but I get the error "The file 'doc' was illegal uploaded, possible attack". I managed to get past this problem by not creating a new Zend_File_Transfer_Adapter_Http() but instead using: $adapter = $form->doc->getTransferAdapter(); With this modification, the first error disappears but now I have an error saying I have provided 2 files instead of one (probably its reading the temp) and when I adjust the validator to accept two files I then get the arror saying "The file 'doc' was not found" and the upload now fails completely.

  • Iterating through folders and files in batch file?

    - by Will Marcouiller
    Here's my situation. A project has as objective to migrate some attachments to another system. These attachments will be located to a parent folder, let's say "Folder 0" (see this question's diagram for better understanding), and they will be zipped/compressed. I want my batch script to be called like so: BatchScript.bat "c:\temp\usd\Folder 0" I'm using 7za.exe as the command line extraction tool. What I want my batch script to do is to iterate through the "Folder 0"'s subfolders, and extract all of the containing ZIP files into their respective folder. It is obligatory that the files extracted are in the same folder as their respective ZIP files. So, files contained in "File 1.zip" are needed in "Folder 1" and so forth. I have read about the FOR...DO command on Windows XP Professional Product Documentation - Using Batch Files. Here's my script: @ECHO OFF FOR /D %folder IN (%%rootFolderCmdLnParam) DO FOR %zippedFile IN (*.zip) DO 7za.exe e %zippedFile I guess that I would also need to change the actual directory before calling 7za.exe e %zippedFile for file extraction, but I can't figure out how in this batch file (through I know how in command line, and even if I know it is the same instruction "cd"). Anyone's help is gratefully appreciated.

  • Figuring out the Nyquist performance limitation of an ADC on an example PIC microcontroller

    - by AKE
    I'm spec-ing the suitability of a dsPIC microcontroller for an analog-to-digital application. This would be preferable to using dedicated A/D chips and a separate dedicated DSP chip. To do that, I've had to run through some computations, pulling the relevant parameters from the datasheets. I'm not sure I've got it right -- would appreciate a check! (EDITED NOTE: The PIC10F220 in the example below was selected ONLY to walk through a simple example to check that I'm interpreting Tacq, Fosc, TAD, and divisor correctly in working through this sort of Nyquist analysis. The actual chips I'm considering for the design are the dsPIC33FJ128MC804 (with 16b A/D) or dsPIC30F3014 (with 12b A/D).) A simple example: PIC10F220 is the simplest possible PIC with an ADC Runs at clock speed of 8MHz.

Is this a correct interpretation of the information given in the data sheet in obtaining the Nyquist performance limit? Any opinions on the noise susceptibility of ADCs in PIC / dsPIC chips would be much appreciated! AKE

How do I retrieve the JPEG file in that case ? Because if I use parameters, there is no more BinaryRead... Aspecially, how would I read an array of jpeg files (several files) ?

    I'm trying to build a Python extension on MacOSX 10.6 and to link it against several frameworks (i386 only). I made a setup.py file, using distutils and the Extension object. I order to link against my frameworks, my LDFLAGS env var should look like : LDFLAGS = -lc -arch i386 -framework fwk1 -framework fwk2 As I did not find any 'framework' keyword in the Extension module documentation, I used the extra_link_args keyword instead. Extension('test', define_macros = [('MAJOR_VERSION', '1'), ,('MINOR_VERSION', '0')], include_dirs = ['/usr/local/include', 'include/', 'include/vitale'], extra_link_args = ['-arch i386', '-framework fwk1', '-framework fwk2'], sources = "testmodule.cpp", language = 'c++' ) Everything is compiling and linking fine. If I remove the -framework line from the extra_link_args, my linker fails, as expected. Here is the last two lines produced by a python setup.py build : /usr/bin/g++-4.2 -arch x86_64 -arch i386 -isysroot / -L/opt/local/lib -arch x86_64 -arch i386 -bundle -undefined dynamic_lookup build/temp.macosx-10.6-intel-2.6/testmodule.o -o build/lib.macosx-10.6-intel-2.6/test.so -arch i386 -framework sgdosx -framework srtosx -framework ssvosx -framework stsosx Unfortunately, the .so that I just produced is unable to find several symbols provided by this framework. I tried to check the linked framework with otool. None of them is appearing. $ otool -L test.so test.so: /usr/lib/libstdc++.6.dylib (compatibility version 7.0.0, current version 7.9.0) /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 125.0.1) There is the output of otool run on a test binary, made with g++ and ldd using the LDFLAGS described at the top of my post. On this example, the -framework did work. $ otool -L vitaosx vitaosx: /Library/Frameworks/sgdosx.framework/Versions/A/sgdosx (compatibility version 1.0.0, current version 1.0.0) /Library/Frameworks/ssvosx.framework/Versions/A/ssvosx (compatibility version 1.0.0, current version 1.0.0) /usr/lib/libstdc++.6.dylib (compatibility version 7.0.0, current version 7.9.0) /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 125.0.1) May this issue be linked to the "-undefined dynamic_lookup" flag on the linking step ? I'm a little bit confused by the few lines of documentation that I'm finding on Google. Cheers,

  • Space in Directory Parameter of svcutil.exe

    - by Drew Frisk
    I'm attempting to download metadata for a WCF service using svcutil but I'm running into issues with the /directory:< parameter. The directory I want to save to has a space in it: C:\Service References\Logging so when I execute /t:metadata I receive the following error: Error: The directory 'C:\Program Files (x86)\Microsoft SDKs\Windows\v8.0A\bin\NETFX 4.0 Tools\References\Logging' could not be found. Verify that the directory exists and that you have the appropriate permissions to read it. It looks to me like the space in "Service References" is causing the issue. From my understanding of command shell (which is very little) spaces act as delimiters for an executable. So I tried escaping the space with a carrot Service^ References and surrounding the path in double quotes "C:\Service References\Logging" but neither of those seem to be working, as the /directory: parameter doesn't recognize them as valid characters in the value. I haven't been able to find any direction in regards to this and svcutil, so I'm at a loss right now. I could download the files to a temp folder and then move them, but I would prefer not to take that approach. I would appreciate any direction that could be given on trying to resolve this. Thanks in advance.

  • Log4net Logging Problem : Very simple file appender logging not working

    - by contactmatt
    Here's my web.config information <configSections> <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net"/> </configSections> <log4net> <root> <level value="ALL" /> </root> <appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender"> <file value="c:\temp\log-file.txt" /> <appendToFile value="true" /> <rollingStyle value="Size" /> <maxSizeRollBackups value="10" /> <maximumFileSize value="1MB" /> <staticLogFileName value="true" /> <layout type="log4net.Layout.SimpleLayout" /> </appender> </log4net> ... Here's the code that initalizes the logger protected void SendMessage() { log4net.Config.XmlConfigurator.Configure(); ILog log = LogManager.GetLogger(typeof(Contact)); ... log.Info("here we go!"); log.Debug("debug afasf"); ... } it doesn't work, no matter what I seem to do. I am referencing the 'log4net.dll' correctly, and by debugging the application i can see that the log object is getting initiated properly. This is a asp.net 3.5 framework web project. Any ideas/suggestions? I thought originally this error may be due to a file write permission constraint, but that doesn't seem to be the case (or so I think).

  • Matching a Repeating Sub Series using a Regular Expression with PowerShell

    - by Hinch
    I have a text file that lists the names of a large number of Excel spreadsheets, and the names of the files that are linked to from the spreadsheets. In simplified form it looks like this: "Parent File1.xls" Link: ChildFileA.xls Link: ChildFileB.xls "ParentFile2.xls" "ParentFile3.xls" Blah Link: ChildFileC.xls Link: ChildFileD.xls More Junk Link: ChildFileE.xls "Parent File4.xls" Link: ChildFileF.xls In this example, ParentFile1.xls has embedded links to ChildFileA.xls and ChildFileB.xls, ParentFile2.xls has no embedded links, and ParentFile3.xls has 3 embedded links. I am trying to write a regular expression in PowerShell that will parse the text file producing output in the following form: ParentFile1.xls:ChildFileA.xls,ChildFileB.xls ParentFile3.xls:ChildFileC.xls,ChildFileD.xls,ChildFileE.xls etc The task is complicated by the fact that the text file contains a lot of junk between each of the lines, and a parent may not always have a child. Furthermore, a single file name may pass over multiple lines. However, it's not as bad as it sounds, as the parent and child file names are always clearly demarcated (the parent with quotes and the child with a prefix of Link: ). The PowerShell code I've been using is as follows: $content = [string]::Join([environment]::NewLine, (Get-Content C:\Temp\text.txt)) $regex = [regex]'(?im)\s*\"(.*)\r?\n?\s*(.*)\"[\s\S]*?Link: (.*)\r?\n?' $regex.Matches($content) | %{$_.Groups[1].Value + $_.Groups[2].Value + ":" + $_.Groups[3].Value} Using the example above, it outputs: ParentFile1.xls:ChildFileA.xls ParentFile2.xls""ParentFile3.xls:ChildFileC.xls ParentFile4.xls:ChildFileF.xls There are two issues. Firstly, the inclusion of the "" instead of a newline whenever a Parent without a Child is processed. And the second issue, which is the most important, is that only a single child is ever shown for each parent. I'm guessing I need to somehow recursively capture and display the multiple child links that exist for each parent, but I'm totally stumped as to how to do this with a regular expression. Amy help would be greatly appreciated. The file contains 100's of thousands of lines, and manual processing is not an option :)

  • Access Denied while using System.Diagnostics.Process

    - by Mike C
    I am trying to use the unmanaged ImageMagick library in my ASP.NET application from the command line using System.Diagnostics.Process. Basically, users will upload an .eps file to the site, and then I will run the command line command to convert it into .jpg. This is the code I'm using to try and run the command: Dim proc As New System.Diagnostics.Process proc.StartInfo.RedirectStandardOutput = True proc.StartInfo.RedirectStandardError = True proc.StartInfo.FileName = "C:\Program Files (x86)\ImageMagick-6.6.1-Q16\convert.exe" proc.StartInfo.UseShellExecute = False proc.StartInfo.Arguments = String.Format("{0} {1}", Server.MapPath("~/logo/test.eps"), _ Server.MapPath("~/certificates/temp/test-1234.jpg")) proc.StartInfo.CreateNoWindow = True proc.Start() I am able to run this code just fine on our development Win 2k3 server, but not on our production Win 2k3 Server. I get the error "System.ComponentModel.Win32Exception: Access is denied". The main between the two servers is that the production is 64-bit and runs Plesk to manage multiple domains. I've tried adding rights asp.net user to the ImageMagick directory. The PS Admin says that in the case of Plesk, it's the same account that I use to access the site in VS using FPE. Does anyone know what I might do in order to allow this process to run on my production server? Thanks, Mike

  • How to pass binary data between two apps using Content Provider?

    - by Viktor
    I need to pass some binary data between two android apps using Content Provider (sharedUserId is not an option). I would prefer not to pass the data (a savegame stored as a file, small in size < 20k) as a file (ie. overriding openFile()) since this would necessitate some complicated temp-file scheme to cope with concurrency with several content provider accesses and a running game. I would like to read the file into memory under a mutex lock and then pass the binary array in the simplest way possible. How do I do this? It seems creating a file in memory is not a possibility due to the return type of openFile(). query() needs to return a Cursor. Using MatrixCursor is not possible since it applies toString() to all stored objects when reading it. What do I need to do? Implement a custom Cursor? This class has 30 abstract methods. Do I read the file, put it in a SQLite db and return the cursor? The complexity of this seemingly simple task is mindboggling.

  • JOAL with JNLPAppletLauncher Problem

    - by user347445
    Hi, I am developing a Java Applet that makes use of JOAL. In order to avoid annoying dialogues I wanted to load JOAL with the JNLPAppletLauncher as it is shown on https://jogl-demos.dev.java.net/applettest-joal.html Unfortunately with this approach I get this exception: JNLPAppletLauncher.loadLibrary("joal_native") loading: C:\Users\Barbara\AppData\Local\Temp\jnlp-applet\jln7379734545861869319\jln1640167325490042232\joal_native.dll Exception in thread "AWT-EventQueue-2" java.lang.RuntimeException: Can not get proc address for method "alcCaptureCloseDevice": Couldn't set value of field "_addressof_alcCaptureCloseDevice" in class net.java.games.joal.impl.ALCProcAddressTable at com.sun.gluegen.runtime.ProcAddressHelper.resetProcAddressTable(ProcAddressHelper.java:113) at net.java.games.joal.impl.ALProcAddressLookup.resetALCProcAddressTable(ALProcAddressLookup.java:109) at net.java.games.joal.impl.ALCImpl.alcOpenDevice(ALCImpl.java:341) at net.java.games.joal.util.ALut.alutInit(ALut.java:69) at demos.devmaster.lesson1.SingleStaticSource.initialize(SingleStaticSource.java:194) at demos.devmaster.lesson1.SingleStaticSource.access$000(SingleStaticSource.java:57) at demos.devmaster.lesson1.SingleStaticSource$1.actionPerformed(SingleStaticSource.java:79) at javax.swing.AbstractButton.fireActionPerformed(Unknown Source) at javax.swing.AbstractButton$Handler.actionPerformed(Unknown Source) at javax.swing.DefaultButtonModel.fireActionPerformed(Unknown Source) at javax.swing.DefaultButtonModel.setPressed(Unknown Source) at javax.swing.plaf.basic.BasicButtonListener.mouseReleased(Unknown Source) at java.awt.Component.processMouseEvent(Unknown Source) at javax.swing.JComponent.processMouseEvent(Unknown Source) at java.awt.Component.processEvent(Unknown Source) at java.awt.Container.processEvent(Unknown Source) at java.awt.Component.dispatchEventImpl(Unknown Source) at java.awt.Container.dispatchEventImpl(Unknown Source) at java.awt.Component.dispatchEvent(Unknown Source) at java.awt.LightweightDispatcher.retargetMouseEvent(Unknown Source) at java.awt.LightweightDispatcher.processMouseEvent(Unknown Source) at java.awt.LightweightDispatcher.dispatchEvent(Unknown Source) at java.awt.Container.dispatchEventImpl(Unknown Source) at java.awt.Component.dispatchEvent(Unknown Source) at java.awt.EventQueue.dispatchEvent(Unknown Source) at java.awt.EventDispatchThread.pumpOneEventForFilters(Unknown Source) at java.awt.EventDispatchThread.pumpEventsForFilter(Unknown Source) at java.awt.EventDispatchThread.pumpEventsForHierarchy(Unknown Source) at java.awt.EventDispatchThread.pumpEvents(Unknown Source) at java.awt.EventDispatchThread.pumpEvents(Unknown Source) at java.awt.EventDispatchThread.run(Unknown Source) Caused by: java.lang.RuntimeException: Unable to find and load OpenAL library at net.java.games.joal.impl.ALProcAddressLookup$DynamicLookup.dynamicLookupFunction(ALProcAddressLookup.java:66) at com.sun.gluegen.runtime.ProcAddressHelper.resetProcAddressTable(ProcAddressHelper.java:106) ... 30 more I am using Firefox 3.6.3, Java 1.6._017 and am on a Windows 7 Machine. I also tried this on another computer with Windows XP and on one with Linux, always with the same result, so it does not seem to be specific for my computer. I also get the same result for IE8. Any ideas how I could fix this? Thank you very much.

  • Debug Symbols not loading

    - by FunkyFresh84
    I am trying to enable visual studio to step through the .net framework source code when I am debugging. I have tried with both Visual Web-Developer-Express-2010 and Visual-Studio-2011-Express-For-Web and I am getting the same problem with each. When I get to the break point at the .net method I wish to step into I do right-clickstep-into-specificclick-method-to-step-into. Then VS opens a new tab. saying it couldn't find or load the symbols. It gives a list of the assembly symbols it looked for. There is also a 'Load Symbols hyperlink which doesn't work. And another hyperlink that takes me to the debug settings dialog. I have read tutorials on how to set it up and have believe I have the correct settings. In the debugging general settings I have - enable address-level debugging - checked enable source server support - checked enable .net framework source stepping - checked enable just my code - not checked In the debugging symbol settings I have - symbol file (.pdb) locations - Microsoft Symbol Servers - checked Caching Directory - C:\Users\MyAccount\AppData\Local\Temp\SymbolCache Automatically load symbols for: all modules unless excluded - checked Why is it not working? Thank you for your help. edit: here is a screenshot of the error VS is giving me.
