  • When can a == b be false and a.Equals(b) true?

    - by alastairs
    I ran into this situation today. I have an object which I'm testing for equality; the Create() method returns a subclass implementation of MyObject. MyObject a = MyObject.Create(); MyObject b = MyObject.Create(); a == b; // is false a.Equals(b); // is true Note I have also over-ridden Equals() in the subclass implementation, which does a very basic check to see whether or not the passed-in object is null and is of the subclass's type. If both those conditions are met, the objects are deemed to be equal. The other slightly odd thing is that my unit test suite does some tests similar to Assert.AreEqual(MyObject.Create(), MyObject.Create()); // Green bar and the expected result is observed. Therefore I guess that NUnit uses a.Equals(b) under the covers, rather than a == b as I had assumed. Side note: I program in a mixture of .NET and Java, so I might be mixing up my expectations/assumptions here. I thought, however, that a == b worked more consistently in .NET than it did in Java where you often have to use equals() to test equality.

  • CodeDom : compile partial class

    - by James
    I'm attempting to compile code in a text file to change a value in a TextBox on the main form of a WinForms application. Ie. add another partial class with method to the calling form. The form has one button (button1) and one TextBox (textBox1). The code in the text file is: this.textBox1.Text = "Hello World!!"; And the code: namespace WinFormCodeCompile { public partial class Form1 : Form { public Form1() { InitializeComponent(); } private void button1_Click(object sender, EventArgs e) { // Load code from file StreamReader sReader = new StreamReader(@"Code.txt"); string input = sReader.ReadToEnd(); sReader.Close(); // Code literal string code = @"using System; using System.Windows.Forms; namespace WinFormCodeCompile { public partial class Form1 : Form { public void UpdateText() {" + input + @" } } }"; // Compile code CSharpCodeProvider cProv = new CSharpCodeProvider(); CompilerParameters cParams = new CompilerParameters(); cParams.ReferencedAssemblies.Add("mscorlib.dll"); cParams.ReferencedAssemblies.Add("System.dll"); cParams.ReferencedAssemblies.Add("System.Windows.Forms.dll"); cParams.GenerateExecutable = false; cParams.GenerateInMemory = true; CompilerResults cResults = cProv.CompileAssemblyFromSource(cParams, code); // Check for errors if (cResults.Errors.Count != 0) { foreach (var er in cResults.Errors) { MessageBox.Show(er.ToString()); } } else { // Attempt to execute method. object obj = cResults.CompiledAssembly.CreateInstance("WinFormCodeCompile.Form1"); Type t = obj.GetType(); t.InvokeMember("UpdateText", BindingFlags.InvokeMethod, null, obj, null); } } } } When I compile the code, the CompilerResults returns an error that says WinFormCodeCompile.Form1 does not contain a definition for textBox1. Is there a way to dynamically create another partial class file to the calling assembly and execute that code? I assume I'm missing something really simple here.

  • PowerShell: How to find and uninstall a MS Office Update

    - by Hank
    I've been hunting for a clean way to uninstall an MSOffice security update on a large number of workstations. I've found some awkward solutions, but nothing as clean or general like using PowerShell and get-wmiobject with Win32_QuickFixEngineering and the .Uninstall method on the resulting object. [Apparently, Win32_QuickFixEngineering only refers to Windows patches. See: http://social.technet.microsoft.com/Forums/en/winserverpowershell/thread/93cc0731-5a99-4698-b1d4-8476b3140aa3 ] Question 1: Is there no way to use get-wmiobject to find MSOffice updates? There are so many classes and namespaces, I have to wonder. This particualar Office update (KB978382) can be found in the registry here (for Office Ultimate): HKLM\Software\Microsoft\Windows\CurrentVersion\Uninstall\{91120000-002E-0000-0000-0000000FF1CE}_ULTIMATER_{6DE3DABF-0203-426B-B330-7287D1003E86} which kindly shows the uninstall command of: msiexec /package {91120000-002E-0000-0000-0000000FF1CE} /uninstall {6DE3DABF-0203-426B-B330-7287D1003E86} and the last GUID seems constant between different versions of Office. I've also found the update like this: $wu = new-object -com "Microsoft.Update.Searcher" $wu.QueryHistory(0,$wu.GetTotalHistoryCount()) | where {$_.Title -match "KB978382"} I like this search because it doesn't require any poking around in the registry, but: Question 2: If I've found it like this, what can I do with the found information to facilitate the Uninstall? Thanks

  • XNA 2D mouse picking

    - by Corndog
    I'm working on a simple 2D Real time strategy game using XNA. Right now I have reached the point where I need to be able to click on the sprite for a unit or building and be able to reference the object associated with that sprite. From the research I have done over the last three days I have found many references on how to do "Mouse picking" in 3D which does not seem to apply to my situation. I understand that another way to do this is to simply have an array of all "selectable" objects in the world and when the player clicks on a sprite it checks the mouse location against the locations of all the objects in the array. the problem I have with this approach is that it would become rather slow if the number of units and buildings grows to larger numbers. (it also does not seem very elegant) so what are some other ways I could do this. (Please note that I have also worked over the ideas of using a Hash table to associate the object with the sprite location, and using a 2 dimensional array where each location in the array represents one pixel in the world. once again they seem like rather clunky ways of doing things.)

  • Apple Script error: Can't get Folder

    - by Jonathan Hirsch
    I started using apple script today, because I wanted to be able to automatically send files to someone when they go into a specific folder. I first tried with automator, but the files were never attached into emails, so i figured i could try with apple script. At first, I tried simply create an email with an attached file. The email was created, but the file was not attached. After a while, I stumbled onto this post that was trying to list files from a folder, so I tried that just to compare it to my code. It gave me an error telling me it is impossible to list files from that folder. So I tried setting a path to a specific folder, and I got an error saying the path can't be made. This is the code I used for the last part: tell application "Finder" set folderPath to folder "Macintosh HD: Users:Jonathan:Desktop:Send_Mail" set fileList to name of every file in folderPath end tell and this is the error I got. error "Finder got an error: Can’t get folder \"Macintosh HD: Users:Jonathan:Desktop:Send_Mail\"." number -1728 from folder "Macintosh HD: Users:Jonathan:Desktop:Send_Mail". I later tried with another folder, and I always get this error, even when using the Users folder for example. Any Suggestions? thanks

  • Java invokeAndWait of C# Action Delegate

    - by ikurtz
    the issue i mentioned in this post is actually happening because of cross threading GUI issues (i hope). could you help me with Java version of action delegate please? in C# it is done as this inline: this.Invoke(new Action(delegate() {...})); how is this achived in Java? thank you. public class processChatMessage implements Observer { public void update(Observable o, Object obj) { System.out.println("class class class" + obj.getClass()); if (obj instanceof String){ String msg = (String)obj; formatChatHeader(chatHeader.Away, msg); jlStatusBar.setText("Message Received"); // Show chat form setVisibility(); } } } processChatMessage is invoked by a separate thread triggered by receiving new data from a remote node. and i think the error is being produced as it trying to update GUI controls. do you think this is the reason? i ask because im new to Java and C#, but this is what is going on i think. SOLUTION: public class processChatMessage implements Observer { public void update(Observable o, Object obj) { if (obj instanceof String){ final String msg = (String)obj; try { SwingUtilities.invokeAndWait(new Runnable( ) { public void run( ) { formatChatHeader(chatHeader.Away, msg); jlStatusBar.setText("Message Received"); setVisibility(); } }); } catch (InterruptedException e){ } catch (InvocationTargetException e){ } } } }

  • How to avoid "Illegal type in constant pool" using "ldc_w <classname>" in Jasmin?

    - by jazzdev
    I'm writing a compiler that generates Jasmin code and want to invoke a method that takes a Class as a parameter. public class CTest { public static void main(String[] args) throws Exception { java.lang.reflect.Array.newInstance(CTest.class, 0); } } So in Jasmin, I think that should be: .class public CTest2 .super java/lang/Object .method public static main([Ljava/lang/String;)V .limit stack 2 .limit locals 1 ldc_w CTest2 iconst_0 invokestatic java/lang/reflect/Array/newInstance(Ljava/lang/Class;I)Ljava/lang/Object; pop return .end method When I assemble it and run it I get: Exception in thread "main" java.lang.VerifyError: (class: CTest2, method: main signature: ([Ljava/lang/String;)V) Illegal type in constant pool Looking at the disassembled code for both CTest.class (the Java version) and CTest2.class (the Jasmin version) with "javap -c -verbose" they both appear to set up the constant pool the same way: const #2 = class #16; // CTest const #16 = Asciz CTest; 0: ldc_w #2; //class CTest const #14 = Asciz CTest2; const #17 = class #14; // CTest2 0: ldc_w #17; //class CTest2 I've fixed two bugs in Jasmin already, but I can't see what it's doing wrong when putting the class in the constant pool for "ldc_w" it puts classes in the constant pool for other instructions, like "new" and "anewarray" correctly. I've tried looking at the .class files with TraceClassVisitor in ASM, but it doesn't dump the constant pool. Any ideas what I can try next?

  • LinqToSQL Double Insert issue

    - by Vaccano
    I have a WCF service with an object structure similar to this: public class MyClass { public List<MySubItem> SubItems { get; set; } } public class MySubItem { public List<MySubSubItem> SubSubItems { get; set; } } public class MySubSubItem { public string DataValue { get; set; } } public class MyClassDAL { public void InsertMyClass(MyClass myClass) { ctx.MyClasses.InsertOnSubmit(myClass); ctx.SubmitChanges(); } } Sometimes my client will call in with a MyClass that submits only half of the values that it has in the list SubSubItems. Later it calls the insert with the rest of the list. The problem is that when it does this I get a Primary Key violation. The reason is that it is trying to insert the MySubItem again (because there are more items in the SubSubItems owned by the same MySubItem object). How do I deal with this? Do I just call an Update? Do I have to try to separate them out (updates from inserts)? SQL Server 2008 has a really cool Merge functionally. Is there some way to access that from LinqToSQL?

  • PLKs and Web Service Software Factory

    - by Nix
    We found a bug in Web Service Software Factory a description can be found here. There has been no updates on it so we decided to download the code and fix it ourself. Very simple bug and we patched it with maybe 3 lines of code. However* we have now tried to repackage it and use it and are finding that this is seemingly an impossible process. Can someone please explain to me the process of PLKs? I have read all about them but still don't understand what is really required to distribute a VS package. I was able to get it to load and run using a PLK obtained from here, but i am assuming that you have to be a partner to get a functional PLK that will be recognized on other peoples systems? Every time i try and install this on a different computer I get a "Package Load Failure". Is the reason I am getting errors because I am not using a partner key? Is there any other way around this? For instance is there any way we can have an "internal" VS package that we can distribute? Edit Files I had to change to get it to work. First run devenv PostInstall.proj Generate your plks and replace ##Package PLK## (.resx files) --Just note that package version is not the class name but is "Web Service Software Factory: Modeling Edition" -- And you need to remove the new lines from the key ProductDefinitionRegistryFragment.wxi line 1252(update version to whatever version you used in plk) Uncomment all // [VSShell::ProvideLoadKey("Standard", Constant in .tt files.

  • How to pass multiple parameter in DomainService - WCF

    - by S.Amani
    Hi, Let's say I have a window which should submit 3 model in client side (Silverlight Client Application). My problem is each time I submit the form, data on the server side which I passed them from client are empty. I've used nested class which contains my models, instead of passing multiple object as parameter, but it didn't work again. My Personnel Data Transfer Object Code is something like this : [DataContract] public class PersonnelDTO : EntityObject { [Key] [DataMember] public int PersonnelId { get; set; } [Include] [DataMember] [Association("Personnel_ID", "PersonnelId", "Personnel_ID")] public Personnel Personnel { get; set; } [Include] [DataMember] [Association("Personnel_Info_ID", "PersonnelId", "Personnel_Info_ID")] public Personnel_Info PersonnelInfo { get; set; } } I fill up this model to pass data from client to server (DomainService). and also my domain service code is : [Invoke] public void AddPersonnel(PersonnelDTO personnelDTO) { // Model are EMPTY in DTO ObjectContext.AddToPersonnels(personnelDTO.Personnel); ObjectContext.AddToPersonnel_Info(personnelDTO.PersonnelInfo); ObjectContext.SaveChanges(); } I don't know if there is a way to pass multiple parameter in WCF Service method include Generic List. Any advice will be graceful. Thanks.

  • Find TableLeyout in a thread (Because of the ProgressDialog)

    - by Shaulian
    Hi all, On my activity, im getting some big data from web, and while getting this data i want to show the user a ProgressDialog with spinning wheel. That i can do only with putting this code into a thread, right ? the problem is that after im getting this data i need to insert it into my tableLayout as TableRows and it seems impossible to access the TableLayout from the thread. What can i do to show this progress dialog and to be able access the table layout from the thread ?? Is there any event that happens on the end of the thread ? My code fails for : _tableLayout.addView(_tableRowVar, new TableLayout.LayoutParams( LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT)); My full code is : final ProgressDialog dialog = ProgressDialog.show(MyActivity.this, "", "Getting data.\nPlease wait...",true); new Thread() { public void run() { try { TableLayout _tableLayout; _tableLayout = (TableLayout)MyActivity.this.findViewById(R.id.tableLayoutID); List<String> data = getDataFromWeb(); // Get the data and bind it into the table publishTableLayoutWithTableRows(_tableLayout, data ); } catch (Exception e) { new AlertDialog.Builder(MyActivity.this) .setMessage(e.getMessage()) .show(); } dialog.dismiss(); } }.start();

  • How to stop MVC caching the results of invoking and action method?

    - by Trey Carroll
    I am experiencing a problem with IE caching the results of an action method. Other articles I found were related to security and the [Authorize] attribute. This problem has nothing to do with security. This is a very simple "record a vote, grab the average, return the avg and the number of votes" method. The only slightly interesting thing about it is that it is invoked via Ajax and returns a Json object. I believe that it is the Json object that is getting catched. When I run it from FireFox and watch the XHR traffic with Firebug, everything works perfectly. However, under IE 8 the "throbber" graphic doesn't ever have time to show up and the page elements that display the "new" avg and count that are being injected into the page with jQuery are never different. I need a way to tell MVC to never cache this action method. This article seems to address the problem, but I cannot understand it: http://stackoverflow.com/questions/1441467/prevent-caching-of-attributes-in-asp-net-mvc-force-attribute-execution-every-tim I need a bit more context for the solution to understand how to extend AuthorizationAttribute. Please address your answer as if you were speaking to someone who lacks a deep understanding of MVC even if that means replying with an article on some basics/prerequisites that are required. Thanks, Trey Carroll

  • Enormous data and PHP errors

    - by salamis
    I am currently using the following HighCharts:HighStock:Charts: http://www.highcharts.com/stock/demo/data-grouping in order to display the data returned from the server. We retrieve the data from a MySQL database and is really big. We are storing sensor metrics every 1 second. After a while we got the following error: [Wed Sep 12 00:15:56 2012] [error] [client 127.0.0.1] PHP Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 4756882 bytes) in C:\\wamp\\www\\admin\\getTrends.php on line 156, referer: http://localhost/admin/trends.php [Wed Sep 12 00:15:56 2012] [error] [client 127.0.0.1] PHP Stack trace:, referer: http://localhost/admin/trends.php [Wed Sep 12 00:15:56 2012] [error] [client 127.0.0.1] PHP 1. {main}() C:\\wamp\\www\\admin\\getTrends.php:0, referer: http://localhost/admin/trends.php [Wed Sep 12 00:15:56 2012] [error] [client 127.0.0.1] PHP 2. getTrendsDataAI() C:\\wamp\\www\\admin\\getTrends.php:33, referer: http://localhost/admin/trends.php [Wed Sep 12 00:15:56 2012] [error] [client 127.0.0.1] PHP 3. printResults() C:\\wamp\\www\\admin\\getTrends.php:102, referer: http://localhost/admin/trends.php [Wed Sep 12 00:15:56 2012] [error] [client 127.0.0.1] PHP 4. createData() C:\\wamp\\www\\admin\\getTrends.php:230, referer: http://localhost/admin/trends.php [Wed Sep 12 00:15:56 2012] [error] [client 127.0.0.1] PHP 5. implode() C:\\wamp\\www\\admin\\getTrends.php:156, referer: http://localhost/admin/trends.php What is the best solution to return this data as JSON object to HighStocks for viewing? And how can we overcome the PHP limitation? Shall we return chunk of data each time? How do they usually present enormous amount of data to the users and creating charts and reports from this data? Another big problem that we need to overcome is that the returned JSON object is enormous. At this point is around 20-30 mbs and it will be much larger in the future. Is it ok to return this data to the user and perform everything client side? Any suggestions or thoughts welcome.

  • nhibernate many to many deletes

    - by asi farran
    I have 2 classes that have a many to many relationship. What i'd like to happen is that whenever i delete one side ONLY the association records will be deleted with no concern which side i delete. simplified model: classes: class Qualification { IList<ProfessionalListing> ProfessionalListings } class ProfessionalListing { IList<Qualification> Qualifications void AddQualification(Qualification qualification) { Qualifications.Add(qualification); qualification.ProfessionalListings.Add(this); } } fluent automapping with overrides: void Override(AutoMapping<Qualification> mapping) { mapping.HasManyToMany(x => x.ProfessionalListings).Inverse(); } void Override(AutoMapping<ProfessionalListing> mapping) { mapping.HasManyToMany(x => x.Qualifications).Not.LazyLoad(); } I'm trying various combinations of cascade and inverse settings but can never get there. If i have no cascades and no inverse i get duplicated entities in my collections. Setting inverse on one side makes the duplication go away but when i try to delete a qualification i get a 'deleted object would be re-saved by cascade'. How do i do this? Should i be responsible for clearing the associations of each object i delete?

  • Isolated storage misunderstand

    - by Costa
    Hi this is a discussion between me and me to understand isolated storage issue. can you help me to convince me about isolated storage!! This is a code written in windows form app (reader) that read the isolated storage of another win form app (writer) which is signed. where is the security if the reader can read the writer's file, I thought only signed code can access the file! If all .Net applications born equal and have all permissions to access Isolated storage, where is the security then? If I can install and run Exe from isolated storage, why I don't install a virus and run it, I am trusted to access this area. but the virus or what ever will not be trusted to access the rest of file system, it only can access the memory, and this is dangerous enough. I cannot see any difference between using app data folder to save the state and using isolated storage except a long nasty path!! I want to try give low trust to Reader code and retest, but they said "Isolated storage is actually created for giving low trusted application the right to save its state". Reader code: private void button1_Click(object sender, EventArgs e) { String path = @"C:\Documents and Settings\All Users\Application Data\IsolatedStorage\efv5cmbz.ewt\2ehuny0c.qvv\StrongName.5v3airc2lkv0onfrhsm2h3uiio35oarw\AssemFiles\toto12\ABC.txt"; StreamReader reader = new StreamReader(path); var test = reader.ReadLine(); reader.Close(); } Writer: private void button1_Click(object sender, EventArgs e) { IsolatedStorageFile isolatedFile = IsolatedStorageFile.GetMachineStoreForAssembly(); isolatedFile.CreateDirectory("toto12"); IsolatedStorageFileStream isolatedStorage = new IsolatedStorageFileStream(@"toto12\ABC.txt", System.IO.FileMode.Create, isolatedFile); StreamWriter writer = new StreamWriter(isolatedStorage); writer.WriteLine("Ana 2akol we ashrab kai a3eesh wa akbora"); writer.Close(); writer.Dispose(); }

  • How to connect a new query script with SSMS add-in?

    - by squillman
    I'm trying to create a SSMS add-in. One of the things I want to do is to create a new query window and programatically connect it to a server instance (in the context of a SQL Login). I can create the new query script window just fine but I can't find how to connect it without first manually connecting to something else (like the Object Explorer). So in other words, if I connect Obect Explorer to a SQL instance manually and then execute the method of my add-in that creates the query window I can connect it using this code: ServiceCache.ScriptFactory.CreateNewBlankScript( Editors.ScriptType.Sql, ServiceCache.ScriptFactory.CurrentlyActiveWndConnectionInfo.UIConnectionInfo, null); But I don't want to rely on CurrentlyActiveWndConnectionInfo.UIConnectionInfo for the connection. I want to set a SQL Login username and password programatically. Does anyone have any ideas? EDIT: I've managed to get the query window connected by setting the last parameter to an instance of System.Data.SqlClient.SqlConnection. However, the connection uses the context of the last login that was connected instead of what I'm trying to set programatically. That is, the user it connects as is the one selected in the Connection Dialog that you get when you click the New Query button and don't have an Object Explorer connected. EDIT2: I'm writing (or hoping to write) an add-in to automatically send a SQL statement and the execution results to our case-tracking system when run against our production servers. One thought I had was to remove write permissions and assign logins through this add-in which will also force the user to enter a case # canceling the statement if it's not there. Another thought I've just had is to inspect the server name in ServiceCache.ScriptFactory.CurrentlyActiveWndConnectionInfo.UIConnectionInfo and compare it to our list of production servers. If it matches and there's no case # then cancel the query.

  • Question about mixing MEF and Unity

    - by Dave
    I'm finally diving into Unity head first, and have run into my first real problem. I've been gradually changing some things in my app from being MEF-resolved to Unity-resolved. Everything went fine on the application side, but then I realized that my plugins were not being loaded. I started to look into this issue, and I believe it's a case where MEF and Unity don't mix. Plugins are loaded by MEF, but each plugin needs to get access to the shared libraries in my application, like app preferences, logging, etc. Initially, my plugin constructor had the ImportingConstructor attribute. I then replaced it with InjectionConstructor so that Unity could resolve its shared library dependencies. But because I did that, MEF no longer loaded it! Then I used both attributes, which compiled, but then I got a composition error (MEF). I figured that this was because the constructor takes a parameter that was once resolved by a MEF Import, so I removed all parameters. As expected, now MEF was able to load my plugin, but because the constructor needs to call into the interface that was once passed in, construction fails. So now I'm at a point where I can get MEF to start to load my plugin, but can't do anything with it because the plugin relies on shared libraries that are registered with Unity. For those of you that have successfully mixed MEF and Unity, how do you go about resolving the references to the shared libraries with Unity? It seems like a catch-22, where in order to have Unity work with the plugin, I'd have to create the plugin via Resolve, but then it's impossible to use MEF. UPDATE I can work around this problem by using an ImportingConstructor for the plugin that takes an IUnityContainer, and then call Resolve for each interface that I need, but although it works, it is incredibly lame to do it this way, as this would require all plugin authors to remember to save a reference to the passed in IUnityContainer...

  • How to use Java varargs with the GWT Javascript Native Interface? (aka, "GWT has no printf()")

    - by markerikson
    I'm trying to quickly learn GWT as part of a new project. I found out that GWT doesn't implement Java's String.format() function, so there's no printf()-like functionality. I knew that some printf() implementations exist for Javascript, so I figured I could paste one of those in as a GWT Javascript Native Interface function. I ran into problems, and decided I'd better make sure that the varargs values were being passed in correctly. That's where things got ugly. First, some example code: // From Java, call the JSNI function: test("sourceString", "params1", "params2", "params3"); .... public static native void test(Object... params) /*-{ // PROBLEM: this kills GWT! // alert(params.length); // returns "function" alert(typeof(params)); // returns "[Ljava.lang.Object;@b97ff1" alert(params); }-*/; The GWT docs state that "calling a varargs JavaScript method from Java will result in the callee receiving the arguments in an array". I figured that meant I could at least check params.length, but accessing that throws a JavascriptException wrapped in an UmbrellaException, with no real information. When I do "typeof(params)", it returns "function". As if that weren't odd enough, if I check the string value of params, it returns what appears to be a string version of a Java reference. So, I guess I'm asking a few different questions here: 1) How do GWT/JSNI varargs actually work, and do I need to do something special to pass in values? 2) What is actually going on here? 3) Is there any easier way to get printf()-style formatting in a GWT application?

  • VS2008 adding SQL Server Database (SQL Server 2008 Mgmt Studio) not working

    - by Kahn
    I'm trying to practice using the ASP.Net MVC at home, but I ran into an impossible problem. I cannot open a connection to SQL Server 2008, I get this error: "Connections to SQL Server files (*.mdf) require SQL Server Express 2005 to function properly. ..." I've googled around for numerous responses, none of them either working or addressing this issue. I'm running Vista 32bit, my SQL Server 2008 Mgmt Studio is also 32bit, I have SP1 installed both on VS2008 Professional, as well as the SQL Server. I changed the machine.config connectionStrings from ./SQLExpress to my SQL Server 2008 name. Now if I connect manually through web.config, in an asp:datasource or code-behind, everything works fine. But for some reason trying to add a DB Connection directly like this always gets the error. This is pretty fatal, since I can't rightly do much unless I can use LINQ to SQL with my MVC test project, and this is the only way I know how. Worked fine in school and work, but not at home. Installing SQL Server Express 2005, as some have suggested, is not an option. Obviously it HAS to work with SQL Server 2008. Thanks in advance.

  • Flash AS2.0 and JavaScript/jQuery (ExternalInterface) Communication

    - by abysslogic
    Hi there, Im trying to use JS to send data to my Flash AS2.0 music player with ExternalInterface, except there are no good tutorials or guides on ExternalInterface that I can find. I want to be able to change the current song in the player by clicking a JavaScript link, and on page / window load without clicking, play a default song. I dont need a super complicated answer on loading sounds in flash, etc., I am just having a lot of difficulties getting JS to send anything to Flash, and when I get that to work - would I need to put some if / else into the flash to determine if the link has been clicked or not? Thanks edit heres the code as of now: AS 2.0 import flash.external.ExternalInterface; ExternalInterface.addCallback('loadSong', null, flashFunction); function flashFunction (val) { extra = val; } JavaScript var flashObj = document.getElementById('VSPLAYER'); function loadSong(val) { return val } HTML <a href="javascript:loadSong('2')">Play song 2</a> <object id="VSPLAYER" type="application/x-shockwave-flash" data="vs_player.swf" width="280" height="90"> <param name="movie" value="vs_player.swf" /> <param name="allowscriptaccess" value="always" /> </object>

  • How to remove all ListBox items?

    - by Nano HE
    Hi, I created two RadioButton (Weight and Height). I will do switch between the two categories. But the they share the same ListBox Controllers (listBox1 and listBox2). Is there any good method to clear all the ListBox items simpler? I didn't find the removeAll() for ListBox. I don't like my complex multi-lines style which I posted here. private void Weight_Click(object sender, RoutedEventArgs e) { // switch between the radioButton "Weith" and "Height" // Clear all the items first listBox1.Items.Remove("foot"); listBox1.Items.Remove("inch"); listBox1.Items.Remove("meter"); listBox2.Items.Remove("foot"); listBox2.Items.Remove("inch"); listBox2.Items.Remove("meter"); // Add source units items for listBox1 listBox1.Items.Add("kilogram"); listBox1.Items.Add("pound"); // Add target units items for listBox2 listBox2.Items.Add("kilogram"); listBox2.Items.Add("pound"); } private void Height_Click(object sender, RoutedEventArgs e) { // switch between the radioButton "Weith" and "Height" // Clear all the items first listBox1.Items.Remove("kilogram"); listBox1.Items.Remove("pound"); listBox2.Items.Remove("kilogram"); listBox2.Items.Remove("pound"); // Add source units items for listBox1 listBox1.Items.Add("foot"); listBox1.Items.Add("inch"); listBox1.Items.Add("meter"); // Add target units items for listBox2 listBox2.Items.Add("foot"); listBox2.Items.Add("inch"); listBox2.Items.Add("meter"); }

  • Determining failing sectors on portable flash memory

    - by Faxwell Mingleton
    I'm trying to write a program that will detect signs of failure for portable flash memory devices (thumb drives, etc). I have seen tools in the past that are able to detect failing sectors and other kinds of trouble on conventional mechanical hard drives, but I fear that flash memory does not have the same kind of predictable low-level access to the hardware due to the internal workings of the storage. Things like wear-leveling and other block-remapping techniques (to skip over 'dead' sectors?) lead me to believe that determining if a flash drive is failing will be difficult at best, if not impossible (short of having constant read failures and device unmounts). Flash drives at their end-of-life should be easy to detect (constant CRC discrepancies during reads and all-out failure). But what about drives that might be failing early? Are there any tell-tale signs like slower throughput speeds that might indicate a flash drive is going to fail much sooner than normal? Along the lines of detecting potentially bad blocks, I had considered attempting random reads/writes to a file close to or exactly the size of the entire volume, but even then is it possible that the drive might report sizes under its maximum capacity to account for 'dead' blocks? In short, is there any way to circumvent or at least detect (algorithmically or otherwise) the use of block-remapping or other life extension techniques for flash memory? Let me end this question by expressing my uncertainty as to whether or not this belongs on serverfault.com . This is definitely a hardware-related question, but I also desire a software solution - preferably one that I can program myself. If this question is misplaced, I will be happy to migrate it to serverfault - but I do need a programming solution. Please let me know if you need clarification :) Thanks!
