  • How do I use Fluent NHibernate with .NET 4.0?

    - by Tomas Lycken
    I want to learn to use Fluent NHibernate, and I'm working in VS2010 Beta2, compiling against .NET 4, but I'm experiencing some problems. Summary My main problem (at the moment) is that the namespace FluentNHibernate isn't available even though I've imported all the .dll assemblies mentioned in this guide. This is what I've done: 1. I downloaded the Fluent NHibernate source from here, extracted the .zip and opened the solution in VS. A dialog asked me if I wanted to convert the solution to a VS2010 solution, so I did. 2. I then went into each project's properties and configured all of them to compile for .NET 4, and built the entire solution. 3. I copied all the .dll files from /bin/Debug/ in the FluentNHibernate to a new folder on my local hard drive. 4. In my example project, I referenced FluentNHibernate.dll and NHibernate.dll from the new folder. This is my problem: If I right-click on FluentNHibernate in the References list and select "View in Object Browser...", it shows up correctly. Now, when I try to create a mapping class, I can't import FluentNHibernate. This code: using FluentNHibernate.Mapping; namespace FluentNHExample.Mappings { } generates an error on the using statement, saying The type or namespace 'FluentNHibernate' could not be found (are you missing a using directive or an assembly reference?). The FluentNHibernate assembly is still in the list of References of my project, but if I try to browse the assembly in Object Browser again, it can't be found. What is causing this?

  • C# Convert Excel Range to Dataset or Datatable, etc.

    - by htbrady
    I have an Excel spreadsheet that will sit out on a network share drive. It needs to be accessed by my Winforms C# 3.0 application (many users could be using the app and hitting this spreadsheet at the same time). There is a lot of data on one worksheet. This data is broken out into areas that I have named as ranges. I need to be able to access these ranges individually, return each range as a dataset, and then bind it to a grid. I have found examples that use OLE and have got these to work. However, I have seen some warnings about using this method, plus at work we have been using Microsoft.Office.Interop.Excel as the standard thus far. I don't really want to stray from this unless I have to. Our users will be using Office 2003 on up as far as I know. I can get the range I need with the following code: MyDataRange = (Microsoft.Office.Interop.Excel.Range)MyWorkSheet.get_Range("MyExcelRange", Type.Missing); The OLE way was nice as it would take my first row and turn those into columns. My ranges (12 total) are for the most part different from each other in number of columns. Didn't know if this info would affect any recommendations. Is there any way to use Interop and get the returned range back into a dataset? Thanks for your help.

  • Permission denied: .hg\store\lock

    - by harpo
    This smells like a serverfault question, yet there are many similar questions here. Your call. I'm setting up Mercurial over IIS6, and thanks to a number of detailed blogs, it's working fine — almost. I can browse and clone the repositories fine, but this is what happens when I try to push: D:\sample2>hg push pushing to http://localhost/hg/sample2 searching for changes abort: HTTP Error 500: Permission denied: .hg\store\lock First of all, there is no such file or folder. Second, the App Pool's logon has total permission on the repository's parent directory, with these inherited ad infinitum. The repository is located on another logical drive (on the same machine), and if I push to it directly, that also works: D:\sample2>hg push e:\hg\sample2 pushing to e:\hg\sample2 searching for changes adding changesets adding manifests adding file changes added 1 changesets with 1 changes to 1 files If I change the password in my hgrc, the message indicates a failed authorization, so I believe that's working. I've been fighting this for a couple of days, so any leads would be helpful. Thanks!

  • OCR: How to improve accuracy - existing libraries for removing non-text 'furniture', shapes, etc to

    - by Rob
    I want to remove rectangles etc that enclose text in a screenshot image, so that I can perform optical character recognition to get accurate text from the screenshot. Background: I doing this to extract data from a legacy application for use with other applications. This is the only way to get at this data as associated files are in a closed, proprietary, binary format. I will be using AutoItScript to drive the application to show data in its UI, then I will screenshot this and feed this to tesseract. I've already had some success in automating the UI, and have been able to use tesseract to get plain ascii text out of the bitmap. There are several AutoItScripr forum articles discussing its use with tesseract/OCR but not specifically for my question. http://www.autoitscript.com/forum/index.php?s=6c32c3ece12756e635a619cdf175eff9&showforum=2 What I need to do There are thin, 1-pixel wide rectangles that closely enclose some text, when fed to tesseract, it sees them as I for example for a verticle line of the rectangle. Any thoughts on how to remove the rectangles, or best practices? I'm asking if there is a generic command line based toolset to overwrite rectangles, for example, in .png files. I could then pass the .png through this, then pass it to tesseract. Details on the tesseract release/setup I've used are as follows: Go here: http://code.google.com/p/tesseract-ocr/downloads/list - For the basic english generic character set to get Tesseract up and running and recognising your bitmapped text into ascii text, use tesseract-2.00.eng.tar.gz (current version at time of writing is: "English language data for Tesseract (2.00 and up) Jul 2007 989 KB 84845") Related questions I have already looked at on Stack Overflow http://stackoverflow.com/questions/1335581/how-to-give-best-chance-of-success-to-an-ocr-software http://stackoverflow.com/questions/2296568/analysis-and-transformation-of-the-image-on-the-basis-of-this-analysis-for-better http://stackoverflow.com/questions/2268028/reading-characters-off-of-the-screen In these, my question is not completely answered or a commercial solution is being sold. I do not want to consider a commercial solution at this stage.

  • T4 vs CodeDom vs Oslo

    - by Ryan Riley
    In an application scaffolding project on which I'm working, I'm trying to decide whether to use Oslo, T4 or CodeDom for generating code. Our goals are to keep dependencies to a minimum and drive code generation for a domain driven design from user stories. The first step will be to create the tests from the user stories, but we want the domain experts to be able to write their stories in a variety of different media (e.g. custom app, Word, etc.) and still generate the tests from the stories. What I know so far: CodeDom requires .NET but can only output .NET class files (e.g. .cs, .vb). Level of difficulty is fairly high. T4 requires CodeDom and VS Standard+. Level of difficulty is fairly reasonable, especially with the T4 Toolbox. Oslo is very new. I have no idea of the dependencies, but I imagine you must be on at least .NET 3.5. I'm also not certain as to the code generation abilities or the complexity for adding new grammars. However, domain experts could probably write user stories in Intellipad quite easily. Also not sure about ease of converting stories in Word to an MGrammar. What are your thoughts, experiences, etc. with any of the above tools. We want to stick with Microsoft or open source tools.

  • Differing paths for lua script and app

    - by Person
    My problem is that I'm having trouble specifying paths for Lua to look in. For example, in my script I have a require("someScript") line that works perfectly (it is able to use functions from someScript when the script is run standalone. However, when I run my app, the script fails. I believe this is because Lua is looking in a location relative to the application rather than relative to the script. Hardcoding the entire path down to the drive isn't an option since people can download the game wherever they like so the highest I can go is the root folder for the game. We have XML files to load in information on objects. In them, when we specify the script the object uses, we only have to do something like Content\Core\Scripts\someScript.lua where Content is in the same directory as Debug and the app is located inside Debug. If I try putting that (the Content\Core...) in Lua's package.path I get errors when I try to run the script standalone. I'm really stuck, and am not sure how to solve this. Any help is appreciated. Thanks. P.S. When I print out the default package.path in the app I see syntax like ;.\?.lua in a sequence like... ;.\?.lua;c:...(long file path)\Debug\?.lua; I assume the ; means the end of the path, but I have no idea what the .\?.lua means. Any Lua file in the directory?

  • calling CreateFile, specifying FILE_ATTRIBUTE_TEMPORARY | FILE_FLAG_DELETE_ON_CLOSE.

    - by alexander-daniels
    Before I describe my problem, here is a description of the program I'm writting: This is a C++ application. The purpose of my program is to create file on RAM memory. I read that if specify FILE_ATTRIBUTE_TEMPORARY | FILE_FLAG_DELETE_ON_CLOSE when creating file it will be loaded direct to the RAM memory. One of blogs that talk about is this one: http://blogs.msdn.com/larryosterman/archive/2004/04/19/116084.aspx I have built a mini-program, but it not achieves the goal. Instead, it creates a file on hard-drive on directory I specify. Here's my program: void main () { LPCWSTR str = L"c:\temp.txt"; HANDLE fh = CreateFile(str,GENERIC_WRITE,0,NULL,CREATE_ALWAYS, FILE_ATTRIBUTE_TEMPORARY | FILE_FLAG_DELETE_ON_CLOSE,NULL); if (fh == INVALID_HANDLE_VALUE) { printf ("Could not open TWO.TXT"); return; } DWORD dwBytesWritten; for (long i=0; i<20000000; i++) { WriteFile(fh, "This is a test\r\n", 16, &dwBytesWritten, NULL); } return; } I think there problem in CreateFile function, but I can't fix it. Please help me.

  • mysql backup and restore from ib_logfile failure

    - by i need help
    Here's the case: After computer being hacked, we are in a rush to backup all data out to other computer. As a result, the mysql databases are not backup out as sql statement. What we have done is backup out all the physical files/folders in the C drive to new computer. Eg: C:\Program Files\MySQL\MySQL Server 4.1\data In this case, all data for mysql are inside unreadable file. Inside data folder consist of files like ib_logfile0, ib_logfile1, but not ib_data1 All database's table structure format are inside each respective folder. (Some folder have .frm, .opt) (some other folder have .frm, .myd, .myi) How can I retrieve back the data from the database in a new computer? I tried to install the same mysql version(4.1) at new computer, then replace all backup files inside data folder into this mysql in new computer. Then restart mysql service. When I restart, it fail: Could not start mysql service on local computer. error 1067: process terminated unexpectedly.

  • Building Cross Platform app - recommendation

    - by Ben
    Hi, I need to build a fairly simple app but it needs to work on both PC and Mac. It also needs to be redistributable on a disc or usb drive as a standalone desktop app. Initially I thought AIR would be perfect for this (it ticks all the API requirements), but the difficulty is making it distributable, as the app would require the AIR runtime to be installed to run. I came across Shu Player as an option as it seems to be able to package the AIR runtime with the app and do a (silent?) install. However this seems to break the T&C from Adobe (as outlined here) so I'm not sure about the legality. Another option could be Zinc but I haven't tested it so I'm not sure how well it'll fit the bill. What would you recommend or suggest I check out? Any suggestion much appreciated EDIT: There's a few more discussions on mono usage (though no real conclusion): Here and Here EDIT2: Titanium could also fit the bill maybe, will check it out. Any more comments from anyone? Ben

  • PHPUnit Selenium captureScreenshotOnFailure does not work?

    - by user342775
    I am using PHPUnit 3.4.12 to drive my selenium tests. I'd like to be able to get a screenshot taken automatically when a test fails. This should be supported as explained at http://www.phpunit.de/manual/current/en/selenium.html#selenium.seleniumtestcase.examples.WebTest2.php class WebTest { protected $captureScreenshotOnFailure = true; protected $screenshotPath = 'C:\selenium'; protected $screnshotUrl = 'http://localhost/screenshots'; public function testLandingPage($selenium) { $selenium->open("http://www.example.com"); $selenium->fail("fail"); ... } } As you can see, I am making the test to fail and in theory when it does it should take a screenshot and put it in C:\selenium, as I am running the selenium RC server on Windows. However, when I run the test it will just give me the following: [root@testbox selenium]$ sh run PHPUnit 3.4.12 by Sebastian Bergmann. F Time: 8 seconds, Memory: 5.50Mb There was 1 failure: 1) WebTest::testLandingPage fail /home/root/selenium/WebTest.php:32 FAILURES! Tests: 1, Assertions: 0, Failures: 1. I do not see any screenshot in C:\selenium. I can however get a screenshot with $selenium-captureScreenshot("C:/selenium/image.png"); Any ideas or suggestions most welcome. Thanks

  • Microsoft Sync Framework with Mutliple Client and Server Database

    - by David Osborn
    I'm working on changes to an application to have a local data store instead of connecting directly to the database server. The client app will then sync changes both ways between the server database and its local data store. I'm trying to implement the syncing solution using Microsoft Sync Framework. To be clear there is no server application, only the database server, but there are multiple clients. I have started implementing two classes that implement FullEnumerationSimpleSyncProvider, one called LocalSyncProvider and one called ServerSyncProvider. The LocalSyncProvider knows how to enumerate, insert, update, delete items from the local data store, and the ServerSyncProvider knows how to enumerate, insert, update, delete items from the database server. They each use the provided SqlMetadataStore and store the two metadata stores (one for the local and one for the server) on the local drive of the client. This means that each client will have its own metadata store for its local data store and its own metadata store for the server database. Is this actually going to work, does there need to exists only one server metadata store, or do I need to be using the Sync Framework differently?

  • Java Swingworker: Not as encapsulated class

    - by Thomas Matthews
    I'm having problems passing information, updating progress and indicating "done" with a SwingWorker class that is not an encapsulated class. I have a simple class that processes files and directories on a hard drive. The user clicks on the Start button and that launches an instance of the SwingWorker. I would like to print the names of the files that are processed on the JTextArea in the Event Driven Thread from the SwingWorker as update a progress bar. All the examples on the web are for an nested class, and the nested class accesses variables in the outer class (such as the done method). I would also like to signal the Event Driven Thread that the SwingWorker is finished so the EDT can perform actions such as enabling the Start button (and clearing fields). Here are my questions: 1. How does the SwingWorker class put text into the JTextArea of the Event Driven Thread and update a progress bar? How does the EDT determine when the {external} SwingWorker thread is finished? {I don't want the SwingWorker as a nested class because there is a lot of code (and processing) done.}

  • Unable to fetch initial output of "defrag" commad in Windows Server 2008 R2 in WOW64 environment.

    - by Ganesh
    Hi All, [Application & code back ground] I have an MFC application which is executing on Windows Server 2008 R2 in WOW64 environment. In which on user input it defragments the selected drive on the disk. I initiated the process(.i.e. cmd /c defrag –v c:) of defragmentation using the CreateProcess() API, along with this to display output of the process on the main screen I created the pipe using CreatePipe() API. I used PeekNamedPipe() & ReadFile() API to get the output and display. [Problem Area] When the process is launched I am not getting the initial output as below: Microsoft Disk fragmenter Copyright © 2007 Microsoft Crop. Invoking defragmentation on (C:)…. I constantly monitor the output of the process while it is under progress but not able to get any thing as output in the pipe. It seem the process is not doing any thing and appears as if the application is not responding. But after certain period of time, once the process is about to completed I get result along with the initial data. [Sample code] //Pipe created if(0 == ::CreatePipe(&l_hStdOutRead, &l_hStdOutWrite, &l_SecurityAttribute, (DWORD)NULL)) { //Error code } //Process created/launched if (0 == ::CreateProcess(NULL, (LPTSTR)f_csProcessName, &l_stSecurityAttributes, NULL, TRUE, CREATE_NO_WINDOW, NULL,NULL, &l_StartupInfo, &l_CmdPI)) { //Error code } //Read output if (0 == ::PeekNamedPipe(m_hStdOutRead, l_cArrPeekBuffer, (DWORD)NULL, (LPDWORD)NULL, &l_dwAvailable, (LPDWORD)NULL)) { //Return to read again } if (MPLUSFALSE == ::ReadFile(m_hStdOutRead, l_cArrOutput, min(BUFFER_SIZE - 2, l_dwAvailable), &l_dwRead, NULL) || !l_dwRead) { //error code } //Display data. If any one is aware of similar problem or worked on the similar issue please let me know the solution. Thanks in Advance, Ganesh

  • Why is the ASP Repeater.Items collection empty, when controls are on the screen?

    - by Ryan
    I have an ASP page with the following repeater: <asp:Repeater runat="server" ID="RegionRepeater" DataSourceID="SqlDataSourceRegions" EnableViewState="true"> <ItemTemplate> <tr> <td valign="top"> <b><%#Eval("description")%></b> <asp:HiddenField runat="server" ID="RegionID" Value='<%#Eval("region_id")%>'/> </td> <td> <asp:FileUpload ID="FileUpload" runat="server" Width="368px" /> </td> </tr> </ItemTemplate> </asp:Repeater> (The repeater is inside a Wizard, inside a content pane). The code behind is connected to the protected void Wizard1_NextButtonClick(object sender, WizardNavigationEventArgs e) event. There are two items on the screen (two rows inside the table). However, when the code tries to read those items, the Items collection is empty! foreach(RepeaterItem region in RegionRepeater.Items) { // Never runs - the RegionRepeater.Items.Count = 0 FileUpload fileUpload = (FileUpload) region.FindControl("FileUpload"); String regionID = ((HiddenField)region.FindControl("RegionID")).Value; ... Why is the collection empty, when there are controls drawn on the screen? Thanks a lot for any help; this is starting to drive me nuts. (BTW: I tried adding/removing the EnableViewState="true" tag)

  • Integration tests in Continuous Integration environment: Database and filesystem state

    - by dario_ramos
    I'm trying to implement automated integration tests for my application. It's a very complex monster. You could say that its database and part of the filesystem are part of its state, because it saves image files in the hard drive, and references to those in the DB. The software needs all those, in a coherent state, to work properly. Back to writing tests: To run any relevant test, I need some image files in the filesystem, and certain records filled in the database. I thought of putting all of these in a separate folder called TestEnvironmentData in the repository, and retrieving them from the Continuous Integration Server (Team City), but a colleague said the repo is quite full as it is, and that I should set up a special directory, and databases, only in the Continuous Integration server. I don't like that because the tests success depend on me manually mantaining stuff in the server, and restoring initial state before every test becomes cumbersome. What do you guys do when you need to write integration tests for an app like this? The main goal is having an automated test harness to approach a large scale refactoring. There's lots of spaghetti code and the app's current architecture is hardly unit testable, that's why I decided on integration tests first. Any alternative approach is welcome.

  • Request for the permission of type 'System.Web.AspNetHostingPermission' failed when compiling web si

    - by ahsteele
    I have been using Windows 7 for a while but have not had to work with a particular legacy intranet application since my upgrade. Unfortunately, this application is setup as an ASP.NET Website project hosted on a remote server. When I have the website open in Visual Studio 2008 and try to debug it I get the following compiler error: Request for the permission of type 'System.Web.AspNetHostingPermission' failed To resolve this issue on Windows Vista machines, I would change the machine's .NET Security Configuration trust level to full for the local intranet (fix outlined here). I believe this configuration utility relied upon the mscorcfg.msc which from some cursory research appears to be apart of the .NET 2.0 SDK. I have tried to follow the instructions from this Microsoft Support article running the command below to no avail.

  • django-mptt: how to successfully move nodes around

    - by Parand
    django-mptt seems determined to drive me out of my mind. I'm trying to do something relatively simple: I'm going to delete a node, and need to do something reasonable with the node's children. Namely, I'd like to move them up one level so they're children of their current parent's parent. That is, if the tree looks like: Root | Grandpa | Father | | C1 C2 I'm going to delete Father, and would like C1 and C2 to be children of Grandpa. Here's the code I'm using: class Node(models.Model): first_name = models.CharField(max_length=80, blank=True) parent = models.ForeignKey('self', null=True, blank=True, related_name='children') def reparent_children(self, parent): print "Reparenting" for child in self.get_children(): print "Working on", child.first_name, "to parent", parent.email parent = Node.objects.get(id=parent.id) child.move_to(parent, 'last-child') child.save() So I'd call: father.reparent_children(grandpa) father.parent = None father.save() This works - almost. The children report their parents as Grandpa: c1.parent == grandpa # True Grandpa counts C1 and C2 among its children c1 in grandpa.children.all() # True However, Root disowns these kids. c1.get_root() == father # c1's root is father, instead of Root c1 in root.get_descendants() # False How do I get the children to move and their root not get corrupted?

  • Why does Http Web Request and IWebProxy work at wierd times

    - by Mike Webb
    Another question about Web proxy. Here is my code: IWebProxy Proxya = System.Net.WebRequest.GetSystemWebProxy(); Proxya.Credentials = CredentialCache.DefaultNetworkCredentials; HttpWebRequest rqst = (HttpWebRequest)WebRequest.Create(targetServer); rqst.Proxy = Proxya; rqst.Timeout = 5000; try { rqst.GetResponse(); } catch(WebException wex) { connectErrMsg = wex.Message; proxyworks = false; } This code fails the first time it is called. After that on successive calls it works sometimes, but not others. It also never hits the catch block. Now the weird part. If I add a MessageBox.Show(msg) call in the first section of code before the GetResponse() call this all will work every time. Here is an example: try { // ========Here is where I make the call and get the response======== System.Windows.Forms.MessageBox.Show("Getting Response"); // ========This makes the whole thing work every time======== rqst.GetResponse(); } catch(WebException wex) { connectErrMsg = wex.Message; proxyworks = false; } I'm baffled about why it is behaving this way. I don't know if the timeout is not working (it's in milliseconds, not seconds, so should timeout after 5 seconds, right?...) or what is going on. The most confusing this is that the message box call makes it all work. So any help and suggestions on what is happening is appreciated. These are the kind of bugs that drive me absolutely out of my mind.

  • What does SQL Server's BACKUPIO wait type mean?

    - by solublefish
    I'm using Sql Server 2008 ("R1"), with some maintenance plans that back up my databases to a network share. Some of my backup jobs show long waits of type "BACKUPIO". Of course it seems like this is an I/O subsystem limitation, but I'm skeptical. Perfmon stats for I/O on the production (source) server are well within normal trends for that server. The destination server shows a sustained 7MB/s write rate, which seems incredibly low, even for a slow disk. The network link is gigabit ethernet and nowhere near saturated. The few docs I've turned up about BACKUPIO indicate that it's not specifically a wait on I/O, surprisingly enough. This MSFT doc says it's abnormal unless you're using a tape drive, which I'm not. But it doesn't say (or I don't understand) exactly what resource is missing. http://www.docstoc.com/docs/24580659/Performance-Tuning-in-SQL-Server-2005 And this piece says it's not related to I/O performance at all. http://www.informit.com/articles/article.aspx?p=686168&seqNum=5 "Note that BACKUPIO and IO_AUDIT_MUTEX are not related to IO performance." Anyway, does anyone know what BACKUPIO actually means and/or what I can do to diagnose or eliminate it?

I experimented with many commands and coudn't find the way how to force gs to print PDF on my (windows default) network drive. I don't need point exact network printer- default can be used. But if there is no such option I'm happy to pass printer name as well. (I've tried with param -SDevice="\server_IP\printer_name" but this didnt work as well...) Command working under Windows cmd: gswin32c -dPrinted -dBATCH -dNOPAUSE -dNOSAFER -q -dNumCopies=1 -sDEVICE=ljet4 -sOutputFile="\\spool\\\Server_Name\Printer_name" "C:\test.pdf" Method created base on above - doesnt work and thorws exception. (Error code = 1) /// <summary> /// Prints the PDF. /// </summary> /// <param name="ghostScriptPath">The ghost script path. Eg "C:\Program Files\gs\gs8.71\bin\gswin32c.exe"</param> /// <param name="numberOfCopies">The number of copies.</param> /// <param name="printerName">Name of the printer. Eg \\server_name\printer_name</param> /// <param name="pdfFileName">Name of the PDF file.</param> /// <returns></returns> public bool PrintPDF (string ghostScriptPath, int numberOfCopies, string printerName, string pdfFileName) { ProcessStartInfo startInfo = new ProcessStartInfo(); startInfo.Arguments = " -dPrinted -dBATCH -dNOPAUSE -dNOSAFER -q -dNumCopies=" + Convert.ToString(numberOfCopies) + " -sDEVICE=ljet4 -sOutputFile=\"\\\\spool\\" + printerName + "\" \"" + pdfFileName + "\""; startInfo.FileName = ghostScriptPath; startInfo.UseShellExecute = false; Process process = Process.Start(startInfo); return process.ExitCode == 0; } Any idea how to make it working under C#?

  • In need of help with setting up the open source library JFreeChart

    - by ssbellows
    I am having trouble with setting up the open source library JFreeChart for creating charts using Java. This is the process I have followed so far in trying to set it up: I downloaded the latest version from their download page http://sourceforge.net/projects/jfreechart/files/. I then unpacked the jfreechart-1.0.13.zip in the directory C:\JFreeChart\jfreechart-1.0.13\ on my system drive. In the unpacked directory there is a folder entitled "lib" which contains the packaged .jar files specified as necessary to use JFreeChart. I added the following directory to my classpath: C:\JFreeChart\jfreechart-1.0.13\lib\ I then created a simple program and added the line "import org.jfree.chart.*;" to see if it would compile with a package imported from JFreeChart. I navigated to the folder in which my sample program was contained and compiled with the following command: "javac -classpath C:\ Program.java" I was given the following error: "package org.jfree.chart does not exist" Could someone please give me some input as to what I have done incorrectly in this setup process? This is the first time I've tried using an open source library, so I don't have any prior experience to go on myself. Thank you very much in advance.

  • Checking for corrupt war file after mvn install

    - by Tauren
    Is there a maven command that will verify that a WAR file is valid and not corrupt? Or is there some other program or technique to validate zip files? I'm on Ubuntu 9.10, so a linux solution is preferred. On occasion, I end up with a corrupt WAR file after doing mvn clean and mvn install on my project. If I extract the WAR file to my hard drive, an error occurs and the file doesn't get extracted. I believe this happens when my system is in a low-memory condition, because this tends to happen only when lots of memory is in use. After rebooting, doing a mvn install always gives a valid WAR file. Because this happens infrequently, I don't typically test the file by uncompressing it. I transfer the 50MB war file to my server and then restart Jetty with it as the root webapp. But when the file is corrupt, I get a java.util.zip.ZipException: invalid block type error. So I'm looking for a quick way to validate the file as soon as mvn install is completed. Is there a maven command to do this? Any other ideas?

  • Unhandled Exception with c++ app on Visual Studio 2008 release build - occurs when returning from fu

    - by Rich
    Hi, I have a (rather large) application that I have written in C++ and until recently it has been running fine outside of visual studio from the release build. However, now, whenever I run it it says "Unhandled exception at 0x77cf205b in myprog.exe: 0xC0000005: Access violation writing location 0x45000200.", and leads me to "crtexe.c" at line 582 ("mainret = main(argc, argv, envp);") if I attempt to debug it. Note that this problem never shows if I run my debug executable outside of visual studio, or if I run my debug or release build within visual studio. It only happens when running the release build outside of visual studio. I have been through and put plenty of printfs and a couple of while(1)s in it to see when it actually crashed, and found that the access violation occurs at exactly the point that the value is returned from the function (I'm returning a pointer to an object). I don't fully understand why I would get an access violation at the point it returns, and it doesn't seem to matter what I'm returning as it still occurs when I return 0. The point it started crashing was when I added a function which does a lot of reading from a file using ifstream. I am opening the stream every time I attempt to read a new file and close it when I finish reading it. If I keep attempting to run it, it will run once in about 20 tries. It seems a lot more reliable if I run it off my pen drive (it seems to crash the first 3 or 4 times then run fine after that - maybe it's due to its slower read speed). Thanks for your help, and if I've missed anything let me know.

  • SQLite self-join performance

    - by Derk
    What I essentially want, is to retreive all features and values of products which have a particular feature and value. For example: I want to know all available hard drive sizes of products that have an Intel processor. I have three tables: product_to_value (product_id, feature_id, value_id) features (id, value) // for example Processor family, Storage size, etc. values (id, value) // for example Intel, 60GB, etc The simplified query I have now: SELECT features.name, featurevalues.name, featurevalues.value FROM products, products as prod2, features, features as feat2, values, values as val2 WHERE products.feature = features.id AND products.value = values.id AND products.product = prod2.product AND prod2.feature_id = feat2.id AND prod2.value_id = val2.id AND features.id = ? AND feat2.id = ? All columns have an index. I am using SQLite. The problem is that it's very slow (70ms per query, without the self-join it's <1ms). Is there a smarter way to fetch data like this? Or is this too much to ask from SQLite? I personally think I am simply overlooking something, as I am quite new to SQLite.
