• (Fluent) NHibernate Security Exception - ReflectionPermission

  - by PeterEysermans

  I've upgraded an ASP.Net Web application to the latest build of Fluent NHibernate (1.0.0.636) and the newest version of NHibernate (v2.1.2.4000). I've checked a couple of times that the application is running in Full trust. But I keep getting the following error: Security Exception Description: The application attempted to perform an operation not allowed by the security policy. To grant this application the required permission please contact your system administrator or change the application's trust level in the configuration file. Exception Details: System.Security.SecurityException: Request for the permission of type 'System.Security.Permissions.ReflectionPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.

I've seach the web / stackoverflow / NHibernate forums but only found people who had a problem when running in medium trust mode, not full trust. I've been developing for several months on this application on this machine with previous versions of Fluent NHibernate and NHibernate. The machine I'm running this on is 64-bit, you never know that this is relevant.

• How to migrate from XslTransform to XslCompiledTransform

  - by Atara

  I have the following code that I need to migrate from VS 2003 (.Net 1.1) to VS 2008 (.Net 2+) but I get compilation error - System.Xml.Xsl.XslTransform' is obsolete: This class has been deprecated. I probably need to use System.Xml.Xsl.XslCompiledTransform instead. but I do not find the matching Load() and Transform() overload versions that I can use with all the parameters of my original code. in MSDN [How to: Migrate Your XslTransform Code] I only found some simpler cases. http://msdn.microsoft.com/en-us/library/aa983475%28VS.80%29.aspx but in my code I see some remarks that hints that the added parameters were used to avoid exceptions, so I prefer to use these parameters.

• How do I remove a repository of yum

  - by sunil

  When I search for a package in yum(centos 6), it tries to search in a repro named 'c6-media' And it gives a bunch of errors as follows file:///media/CentOS/repodata/repomd.xml: [Errno 14] Could not open/read file:///media/CentOS/repodata/repomd.xml Trying other mirror. file:///media/cdrecorder/repodata/repomd.xml: [Errno 14] Could not open/read file:///media/cdrecorder/repodata/repomd.xml Trying other mirror. file:///media/cdrom/repodata/repomd.xml: [Errno 14] Could not open/read file:///media/cdrom/repodata/repomd.xml Trying other mirror. Error: Cannot retrieve repository metadata (repomd.xml) for repository: c6-media. Please verify its path and try again Obviously the error seems to say that yum is trying to search for the CD/DVD which installed the OS. I do not have it now. All I want to do now is to delete this repository from yum. I went to the package manager graphical tool and removed this from the sources. Seems yum and the graphical tool do not use the same config. This is just my guess.

• Problem with XElement and XslCompiledTransform

  - by Graham Clark

  I'm having some trouble using a combination of XElement and XslCompiledTransform. I've put the sample code I'm using below. If I get my input XML using the GetXmlDocumentXml() method, it works fine. If I use the GetXElementXml() method instead, I get an InvalidOperationException when calling the Transform method of XslComiledTransform: Token Text in state Start would result in an invalid XML document. Make sure that the ConformanceLevel setting is set to ConformanceLevel.Fragment or ConformanceLevel.Auto if you want to write an XML fragment. The CreateNavigator method on both XElement and XmlDocument returns an XPathNavigator. What extra stuff is XmlDocument doing so this all works, and how can I do the same with XElement? Am I just doing something insane? static void Main(string[] args) { XslCompiledTransform stylesheet = GetStylesheet(); // not shown for brevity IXPathNavigable input = this.GetXElementXml(); using (MemoryStream ms = this.TransformXml(input, stylesheet)) { XmlReader xr = XmlReader.Create(ms); xr.MoveToContent(); } } private MemoryStream TransformXml( IXPathNavigable xml, XslCompiledTransform stylesheet) { MemoryStream transformed = new MemoryStream(); XmlWriter writer = XmlWriter.Create(transformed); stylesheet.Transform(xml, null, writer); transformed.Position = 0; return transformed; } private IXPathNavigable GetXElementXml() { var xml = new XElement("x", new XElement("y", "sds")); return xml.CreateNavigator(); } private IXPathNavigable GetXmlDocumentXml() { var xml = new XmlDocument(); xml.LoadXml("<x><y>sds</y></x>"); return xml.CreateNavigator(); }

• chomsky hierarchy and programming languages

  - by dader51

  Hi, I'm trying to learn some aspects of the CH ( chomsky hierarchy ) which are related to PL ( programming languages ), and i still have to read the Dragon Book. I've read that most of the PL can be parsed as CFG ( context free grammar ). In term of computational power, it equals the one of a pushdown non deterministic automaton. Am I right ? If it's true, then how could a CFG holds a UG ( unrestricted grammar, which is turing complete ) ? I'm asking because, even if PL are CFG they are actually used to describe TM (turing machines ) and through UG. I think that's because of at least two different levels of computing, the first, which is the parsing of a CFG focuses on the syntax related to the structure ( representation ? ) of the language, while the other focuses on the semantic ( sense, interpretation of the data itself ? ) related to the capabilities of the pl which is turing complete. Again, are these assumptions rights ? thanx a lot.

• Detecting ClearType-optimized fonts

  - by Josh Kelley

  Question: Is there a way to check if a given font is one of Microsoft's ClearType-optimized fonts? I guess I could simply hard-code the list of font names, since it's a relatively short list, but that seems a bit ugly. Would the font names be the same regardless of Windows' locale and language settings? Background: PuTTY looks really ugly with bold, ClearType-enabled, Consolas text. I decided to play around with the source and see if I could figure out the problem, and I think I tracked it down to the following (abbreviated) code: font_height = cfg.font.height; if (font_height > 0) { font_height = -MulDiv(font_height, GetDeviceCaps(hdc, LOGPIXELSY), 72); } } font_width = 0; #define f(i,c,w,u) \ fonts[i] = CreateFont (font_height, font_width, 0, 0, w, FALSE, u, FALSE, \ c, OUT_DEFAULT_PRECIS, \ CLIP_DEFAULT_PRECIS, FONT_QUALITY(cfg.font_quality), \ FIXED_PITCH | FF_DONTCARE, cfg.font.name) f(FONT_NORMAL, cfg.font.charset, fw_dontcare, FALSE); SelectObject(hdc, fonts[FONT_NORMAL]); GetTextMetrics(hdc, &tm); font_height = tm.tmHeight; font_width = tm.tmAveCharWidth; f(FONT_BOLD, cfg.font.charset, fw_bold, FALSE); The intent is to pick a bold font that fits the same dimensions as the normal font. I'm assuming that PuTTY's Consolas text looks ugly because, since Consolas is so heavily optimized to be layed out on specific pixel boundaries, trying to shoehorn it into arbitrary dimensions produces bad results. So it seems like an appropriate fix would be to detect ClearType-optimized fonts and try and create the bold versions of those fonts using the same width and height as the initial CreateFont call.

• How do I connect to my running VM via virsh?

  - by Avery Chan

  My VM has already been started via virsh start chameleon.ootbdev. When I do a virsh console chameleon.ootbdev I get the following output: Connected to domain chameleon.ootbdev Escape character is ^] error: internal error cannot find character device (null) Doing a google search on this led me to this "solution". Unfortunately, editing the domain via virsh edit chameleon.ootbdev doesn't seem to stick. I suspect the issue is that I'm inserting the XML incorrectly: the instructions from the link ask me to insert the following XML into the domain XML file. <serial type='pty'> <target port='0'/> </serial> <console type='pty'> <target type='serial' port='0'/> </console> I've posted my domain XML file to pastebin here. This is AFTER I've tried to insert the above XML. I inserted this XML after the </devices> block. My primary question is: How do I connect to the running VM? A secondary question would be: How do I edit the domain file with the above XML and get the changes to stick?

• Reusing xalan transformer causing its extension functions break

  - by Leslie Norman

  I am using xalan 2.7.1 to validate my xml docs with xslt style sheet. It works fine for the first document and returns error message in case of error along with correct line and column number of xml source by making use of NodeInfo.lineNumber and NodeInfo.columnNumber extensions. The problem is when I try to reuse transformer to validate other xml docs, it successfully transforms the document but always returns lineNumber=columnNumber=-1 for all errors. Any idea? Here is my code: TransformerFactory tFactory = TransformerFactory.newInstance("org.apache.xalan.processor.TransformerFactoryImpl", null); tFactory.setAttribute(TransformerFactoryImpl.FEATURE_SOURCE_LOCATION, Boolean.TRUE); StreamSource xsltStreamSource = new StreamSource(new File("E:\\Temp\\Test\\myXslt.xsl")); Transformer transformer=null; try { transformer = tFactory.newTransformer(xsltStreamSource); ByteArrayOutputStream outStream = new ByteArrayOutputStream(); File srcFolder = new File("E:\\Temp\\Test"); for (File file :srcFolder.listFiles()) { if (file.getName().endsWith("xml")) { transformer.transform(new StreamSource(file), new StreamResult(outStream)); transformer.reset(); } } System.out.println(outStream.toString()); } catch (TransformerException e) { e.printStackTrace(); } Edit: New code after implementing @rsp suggestions: package mycompany; import java.io.File; import javax.xml.transform.ErrorListener; import javax.xml.transform.Source; import javax.xml.transform.Transformer; import javax.xml.transform.TransformerException; import javax.xml.transform.TransformerFactory; import javax.xml.transform.stream.StreamResult; import javax.xml.transform.stream.StreamSource; import org.apache.xalan.processor.TransformerFactoryImpl; public class XsltTransformer { public static void main(String[] args) { TransformerFactory tFactory = TransformerFactory.newInstance("org.apache.xalan.processor.TransformerFactoryImpl", null); tFactory.setAttribute(TransformerFactoryImpl.FEATURE_SOURCE_LOCATION, Boolean.TRUE); StreamSource xsltStreamSource = new StreamSource(new File("E:\\Temp\\Test\\myXslt.xsl")); try { Transformer transformer = tFactory.newTransformer(xsltStreamSource); File srcFolder = new File("E:\\Temp\\Test"); for (File file : srcFolder.listFiles()) { if (file.getName().endsWith("xml")) { Source source = new StreamSource(file); StreamResult result = new StreamResult(System.out); XsltTransformer xsltTransformer = new XsltTransformer(); ErrorListenerImpl errorHandler = xsltTransformer.new ErrorListenerImpl(); transformer.setErrorListener(errorHandler); transformer.transform(source, result); if (errorHandler.e != null) { System.out.println("Transformation Exception: " + errorHandler.e.getMessage()); } transformer.reset(); } } } catch (TransformerException e) { e.printStackTrace(); } } private class ErrorListenerImpl implements ErrorListener { public TransformerException e = null; public void error(TransformerException exception) { this.e = exception; } public void fatalError(TransformerException exception) { this.e = exception; } public void warning(TransformerException exception) { this.e = exception; } } }

  I trying to use simile widget for own need but I'm stuck on such problem. I have loop for (i=0;i<15;i++){ Timeline.loadXML(function_that_return_url(), function(xml, url) { eventSource[i].loadXML(xml, url); }); } This code is for Timeline.loadXML: Timeline.loadXML = function(url, f) { var fError = function(statusText, status, xmlhttp) { alert("Failed to load data xml from " + url + "\n" + statusText); }; var fDone = function(xmlhttp) { var xml = xmlhttp.responseXML; if (!xml.documentElement && xmlhttp.responseStream) { xml.load(xmlhttp.responseStream); } f(xml, url); }; SimileAjax.XmlHttp.get(url, fError, fDone);}; When I open the page - my function function(xml, url) { eventSource[i].loadXML(xml, url); }); is passed to loadXML method which use it inside as f(xml, url); Problem is that i variable is not parsed as number and I receive message that eventSource[...] is not declared. How I can evaluate i values before it will be posted as argument for the method LoadXML ?

• PHP Curl and Loop based on a numeric value

  - by danit

  Im using the Twitter API to collect the number of tweets I've favorited, well to be accurate the total pages of favorited tweets. I use this URL: http://api.twitter.com/1/users/show/username.xml I grab the XML element 'favorites_count' For this example lets assume favorites_count=5 The Twitter API uses this URL to get the favorties: http://twitter.com/favorites.xml (Must be authenticated) You can only get the last 20 favorties using this URL, however you can alter the URL to include a 'page' option by adding: ?page=3 to the end of the favorites URL e.g. http://twitter.com/favorites.xml?page=2 So what I need to do is use CURL (I think) to collect the favorite tweets, but using the URL: http://twitter.com/favorites.xml?page=1 http://twitter.com/favorites.xml?page=2 http://twitter.com/favorites.xml?page=3 http://twitter.com/favorites.xml?page=4 etc... Some kind of loop to visit each URL, and collect the Tweets and then output the cotents. Can anyone help with this: - Need to use CURL to authenticate - Collect the number of pages of tweets (Already scripted this) - Then use a loop to go through each page URL based on the pages value?

• Understanding Visitor Pattern

  - by Nezreli

  I have a hierarchy of classes that represents GUI controls. Something like this: Control-ContainerControl-Form I have to implement a series of algoritms that work with objects doing various stuff and I'm thinking that Visitor pattern would be the cleanest solution. Let take for example an algorithm which creates a Xml representaion of a hierarchy of objects. Using 'classic' approach I would do this: public abstract class Control { public virtual XmlElement ToXML(XmlDocument document) { XmlElement xml = document.CreateElement(this.GetType().Name); // Create element, fill it with attributes declared with control return xml; } } public abstract class ContainerControl : Control { public override XmlElement ToXML(XmlDocument document) { XmlElement xml = base.ToXML(document); // Use forech to fill XmlElement with child XmlElements return xml; } } public class Form : ContainerControl { public override XmlElement ToXML(XmlDocument document) { XmlElement xml = base.ToXML(document); // Fill remaining elements declared in Form class return xml; } } But I'm not sure how to do this with visitor pattern. This is the basic implementation: public class ToXmlVisitor : IVisitor { public void Visit(Form form) { } } Since even the abstract classes help with implementation I'm not sure how to do that properly in ToXmlVisitor. Perhaps there is a better solution to this problem. The reason that I'm considering Visitor pattern is that some algorithms will need references not available in project where the classes are implemented and there is a number of different algorithms so I'm avoiding large classes. Any thoughts are welcome.

• Creating XSD Dynamically in C Sharp

  - by Nave

  I have two inputs. I get as input one XML file. I have to create an XSD file for this XML file. This XML file has tags which depend on another input. But that XML file should have certain tags for sure. For example, the XML file has the following structure : <A <B <C...</C <D...</D <E <F...</F <G...</G </E </B </A Here, in this XML file, A,B and E tags should be present compulsarily. But the tags C and D inside the B tag and tags F and G inside the E tag depends on another input. So I shoud create an XSD dynamically(i know that A,B and E tags should be present and I do know about the other tags from the other input) and validate the input XML file against the XML Schema. Can someone temme how I can do this in C Sharp?

• Trade off: Lower the number of URLs in sitemap from 43k to 23k or update the sitemap.xml only weekly basis

  - by Tobias

  we rewrote the sitemap creation process. Now the sitemap contains 43.000 URLs. 20k more than before. We have daily changing in URLs. The script that is creating the complete sitemap takes more than 30h. So we can not build it every day. Lets say that increasing the speed of the script is not possible. What should I do? A: Stay with the 23k URLs and update it daily B: Increase number of URLs to 43k and update it weekly

I am following the tutorial for NHibernate posted here and am getting a run-time error of type "HibernateException" The code in question looks like this: using System; using System.Collections.Generic; using System.Linq; using System.Text; using FirstSolution; using NHibernate.Cfg; using NHibernate.Tool.hbm2ddl; using NUnit.Framework; namespace FirstSolution.Tests { [TestFixture] public class GenerateSchema_Fixture { [Test] public void Can_generate_schema() { var cfg = new Configuration(); cfg.Configure(); cfg.AddAssembly(typeof(Product).Assembly); new SchemaExport(cfg).Execute(false, true, false); } } } The line I am getting the error at is: cfg.AddAssembly(typeof(Product).Assembly); The inner-most exception is: The IDbCommand and IDbConnection implementation in the assembly System.Data.SqlServerCe could not be found And here's my stack trace: at NHibernate.Connection.ConnectionProvider.ConfigureDriver(IDictionary`2 settings) at NHibernate.Connection.ConnectionProvider.Configure(IDictionary`2 settings) at NHibernate.Connection.ConnectionProviderFactory.NewConnectionProvider(IDictionary`2 settings) at NHibernate.Tool.hbm2ddl.SchemaExport.Execute(Action`1 scriptAction, Boolean export, Boolean justDrop) at NHibernate.Tool.hbm2ddl.SchemaExport.Execute(Boolean script, Boolean export, Boolean justDrop) at FirstSolution.Tests.GenerateSchema_Fixture.Can_generate_schema() in C:\Users\Kash\Documents\Visual Studio 2010\Projects\FirstSolution\FirstSolution\GenerateSchema_Fixture.cs:line 23 at HibernateUnitTest.Form1.button1_Click(Object sender, EventArgs e) in C:\Users\Kash\Documents\Visual Studio 2010\Projects\FirstSolution\HibernateUnitTest\Form1.cs:line 23 at System.Windows.Forms.Control.OnClick(EventArgs e) at System.Windows.Forms.Button.OnClick(EventArgs e) at System.Windows.Forms.Button.OnMouseUp(MouseEventArgs mevent) at System.Windows.Forms.Control.WmMouseUp(Message& m, MouseButtons button, Int32 clicks) at System.Windows.Forms.Control.WndProc(Message& m) at System.Windows.Forms.ButtonBase.WndProc(Message& m) at System.Windows.Forms.Button.WndProc(Message& m) at System.Windows.Forms.Control.ControlNativeWindow.OnMessage(Message& m) at System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m) at System.Windows.Forms.NativeWindow.DebuggableCallback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam) at System.Windows.Forms.UnsafeNativeMethods.DispatchMessageW(MSG& msg) at System.Windows.Forms.Application.ComponentManager.System.Windows.Forms.UnsafeNativeMethods.IMsoComponentManager.FPushMessageLoop(IntPtr dwComponentID, Int32 reason, Int32 pvLoopData) at System.Windows.Forms.Application.ThreadContext.RunMessageLoopInner(Int32 reason, ApplicationContext context) at System.Windows.Forms.Application.ThreadContext.RunMessageLoop(Int32 reason, ApplicationContext context) at System.Windows.Forms.Application.Run(Form mainForm) at HibernateUnitTest.Program.Main() in C:\Users\Kash\Documents\Visual Studio 2010\Projects\FirstSolution\HibernateUnitTest\Program.cs:line 18 at System.AppDomain._nExecuteAssembly(RuntimeAssembly assembly, String[] args) at System.AppDomain.ExecuteAssembly(String assemblyFile, Evidence assemblySecurity, String[] args) at Microsoft.VisualStudio.HostingProcess.HostProc.RunUsersAssembly() at System.Threading.ThreadHelper.ThreadStart_Context(Object state) at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state, Boolean ignoreSyncCtx) at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state) at System.Threading.ThreadHelper.ThreadStart() I've made sure that System.Data.SqlServerCe has been referenced and that its Copy Local property is set to True. The error persists, however. Your help would be appreciated. Thanks.

• Inside a decorator-class, access instance of the class which contains the decorated method

  - by ifischer

  I have the following decorator, which saves a configuration file after a method decorated with @saveconfig is called: class saveconfig(object): def __init__(self, f): self.f = f def __call__(self, *args): self.f(object, *args) # Here i want to access "cfg" defined in pbtools print "Saving configuration" I'm using this decorator inside the following class. After the method createkvm is called, the configuration object self.cfg should be saved inside the decorator: class pbtools() def __init__(self): self.configfile = open("pbt.properties", 'r+') # This variable should be available inside my decorator self.cfg = ConfigObj(infile = self.configfile) @saveconfig def createkvm(self): print "creating kvm" My problem is that i need to access the object variable self.cfg inside the decorator saveconfig. A first naive approach was to add a parameter to the decorator which holds the object, like @saveconfig(self), but this doesn't work. How can I access object variables of the method host inside the decorator? Do i have to define the decorator inside the same class to get access?

• How to set the build.xml for the Groovy Antbuilder?

  - by Jan

  I want to execute a build.xml (Ant buildfile) from using GMaven (Maven Plugin for inline executing of Groovy in a POM). Since I have to execute the buildfile several times using the maven-antrun-plugin is not an option at the moment. I take a list of properties (environment and machine names) from an xml file and want to execute ant builds for each of those machines. I found the executeTarget method in the javadocs but not how to set the location of the buildfile. How can I do that - and is this enough? What I have looks as follows: <plugin> <groupId>org.codehaus.groovy.maven</groupId> <artifactId>gmaven-plugin</artifactId> <executions> <execution> <id>some ant builds</id> <phase>process-sources</phase> <goals> <goal>execute</goal> </goals> <configuration> <source> def ant = new AntBuilder() def machines = new XmlParser().parse(new File(project.build.outputDirectory + '/MachineList.xml')); machines.children().each { log.info('Creating machine description for ' + it.Id.text() + ' / ' + it.Environment.text()); ant.project.setProperty('Environment',it.Environment.text()); ant.project.setProperty('Machine',it.Id.text()); // What's missing? ant.project.executeTarget('Tailoring'); } log.info('Ant has finished.') </source> </configuration> </execution> </executions> </plugin>

• unit test service layer - NUnit, NHibernate

  - by csetzkorn

  Hi, I would like to unit test a DEPENDENT service layer which allows me to perform CRUD operation without mocking using NUnit. I know this is probably bad practice but I want to give it a try anyway - even if the tests have to run over night. My data is persisted using NHibernate and I have implemented a little library that 'bootstraps' the database which I could use in a [Setup] method. I am just wondering if someone has done something similar and what the fastest method for bootstrapping the database is. I am using something like this: var cfg = new Configuration(); cfg.Configure(); cfg.AddAssembly("Bla"); new SchemaExport(cfg).Execute(false, true, false); to establish the db schema. After that I populate some lookup tables from some Excel tables. Any feedback would be very much appreciated. Thanks. Christian

• Setting a VCProject property to default

  - by Ofek Shilon

  I'm trying some VS2005 IDE macros to modify a large amount of projects (~80) within a solution. Some of the properties I wish to set do expose a programmatic interface to 'default', but many others do not. Is there a generic way to set such properties to their default? (eventually meaning erasing them from the .vcproj file) Simplified example, setting some random properties: Sub SetSomeProps() Dim prj As VCProject Dim cfg As VCConfiguration Dim toolCompiler As VCCLCompilerTool Dim toolLinker As VCLinkerTool Dim EnvPrj As EnvDTE.Project For Each EnvPrj In DTE.Solution.Projects prj = EnvPrj.Object cfg = prj.Configurations.Item(1) toolLinker = cfg.Tools("VCLinkerTool") If toolLinker IsNot Nothing Then ' Some tool props that expose a *default* interface' toolLinker.EnableCOMDATFolding = optFoldingType.optFoldingDefault toolLinker.OptimizeReferences = optRefType.optReferencesDefault toolLinker.OptimizeForWindows98 = optWin98Type.optWin98Default End If toolCompiler = cfg.Tools("VCCLCompilerTool") If toolCompiler IsNot Nothing Then ' How to set it to default? (*erase* the property from the .vcproj)' toolCompiler.CallingConvention = callingConventionOption.callConventionCDecl toolCompiler.WholeProgramOptimization = False toolCompiler.Detect64BitPortabilityProblems = False End If Next End Sub Any advice would be appreciated.

• nhibernate webforms with class library

  - by frosty

  very new to nhibernate. I'm a little confused on where features should live. I have the following solution 1) MyProject.Web ( web forms application) 2) MyProject.Domain( class lib) - nhibernate.config - product.hbm.xml So is it correct I should put the following method in a IHttpModule? ( i can't use a global asax as it's use by the CMS i'm running ) Where should the connectionString live? HTTPModule in web forms application private static ISessionFactory CreateSessionFactory() { var cfg = new Configuration().Configure(Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "nhibernate.config")); cfg.SetProperty(NHibernate.Cfg.Environment.ConnectionStringName, System.Environment.MachineName); NHibernateProfiler.Initialize(); return cfg.BuildSessionFactory(); } nhibernate.config <?xml version="1.0" encoding="utf-8" ?> NHibernate.Dialect.MsSql2005Dialect NHibernate.Connection.DriverConnectionProvider NHibernate.Driver.SqlClientDriver 16 web NHibernate.ByteCode.Castle.ProxyFactoryFactory, NHibernate.ByteCode.Castle enter code here

• BASH tr command

  - by user1457809

  Id like to convert it to uppercase for the simple purpose of formatting so it will adhere to a future case statement. As I thought case statements are case sensitive. I see all over the place the tr command used in concert with echo commands to give you immediate results such as: echo "Enter in Location (i.e. SDD-134)" read answer (user enters "cfg" echo $answer | tr '[:lower:]' '[:upper:]' which produced cfg # first echo not upper? echo $answer #echo it again and it is now upper...
