  • How to best fetch a cell value from excel using VSTO?

    - by Behrooz Karjooravary
    I am trying to get cells from excel into csharp but not sure what's the best variable type to read it into. If I make the variable a string and the cell value is a double I get a parse error. If I make the variable double then when the cell is a string it wont work. Here's the code I am running: try { string i = Globals.Sheet1.Cells[7, 7].Value; double num; if (i == null) return; if (double.TryParse(i, out num)) { . . . } } catch (Exception e) { MessageBox.Show(e.ToString()); }

  • How can I create a simple message box in Python?

    - by Carson Myers
    I'm looking for the same effect as alert() in JavaScript. I wrote a simple web-based interpreter this afternoon using Twisted.web. You basically submit a block of Python code through a form, and the client comes and grabs it and executes it. I want to be able to make a simple popup message, without having to re-write a whole bunch of boilerplate wxPython or TkInter code every time (since the code gets submitted through a form and then disappears). I've tried tkMessageBox: import tkMessageBox tkMessageBox.showinfo(title="Greetings", message="Hello World!") but this opens another window in the background with a tk icon. I don't want this. I was looking for some simple wxPython code but it always required setting up a class and entering an app loop etc. Is there no simple, catch-free way of making a message box in Python?

The object was not updated and there was no error message, why ? How to fix it ?

  • Binding Navigation Property with Entity Framework

    - by JSmaga
    Hi, I have another question about binding using C# and the entity framework. Here, I'm looking to bind a navigation property to a listbox or a listview. I saw on different posts that if I update the collection using code behind the list would not be notified because the collection does not handle notification (it's always the same problem anyway). People suggested to use an ObservableCollection for example, but, and here is my question, this comes down to basically duplicate the collection and hence, if I modify it, I'd have to handle in code-behind the fact that the change has also to be applied to the "original" navigation property right? If that's the case, I was thinking: why not create a custom property called, say, MyObservableNavigationProperty in a partial class. I could then interact only with this collection, catch the event when the collection is changed and apply the change to the "original" collection. Is that a nice way to do the trick? or am I getting all confused here....

  • Manual stack backtrace on Windows mobile (SEH)

    - by caahab
    Following situation: I'm developing an windows mobile application using the sdk 6. Target machine is a nautiz x7. To improve the error reporting I want to catch the structured exceptions (SEH) and do a stack backtrace to store some information for analysis. So far I have the information where the exception was thrown (windows core.dll) and I can backtrace the return adresses thru the stack. But what I want to know is, which instruction in my code caused the exception? Does anyone know how to use the available exception and context information to get the appropriate function/instruction address? Unfortunately windows mobile 6 sdk for pocketpc does not support all the helper functions to do stackwalks or mini dumps.

  • Compiling a class using Java code using process

    - by Noona
    I have this piece of code that compiles a class called tspClassName, when I compile using this code: Process compileProc = null; try { compileProc = Runtime.getRuntime().exec("javac -classpath ." + File.separator + "src" + File.separator + File.separator + "generated." + tspClassName + ".java -d ." + File.separator + "bin"); // catch exception if (compileProc.exitValue() != 0) { System.out.println("Compile exit status: " + compileProc.exitValue()); System.err.println("Compile error:" + compileProc.getErrorStream()); it outputs this: "Compile exit status: 2 Compile error:java.io.FileInputStream@17182c1" The class tspClassName.java compiles without errors otherwise, so I am guessing it has to do with the path,and in my eclipse project, the tspClassName.java resides in package homework4.generated inside src, is there something wrong with the path that I use in the code? thanks

  • Asp.net error object not set to a reference

    - by Frank
    Hi all, Because I rush in development (a lot of whip cracking here) and declare my objects at the top of the function and instantiate inside my try-catch block, I get a lot of the good old "object not set to an instance of an object" errors while doing TDD, and later if I do miss a branch that object was used in (doing VB now, would prefer C#) or just in every day coding, object not set to an instance of an object is a bit vague. Sure the stack trace sends me to the line the error occured at, but it would be nice if I could modify my logging to either name the object or its type because sometimes I have multiple objects on the same line. It's not the end of the world, but in the end it would save me a few minutes each day. Any ideas on how I can pass the info on which object wasn't set? Thanks

  • Controlling CodeModel's code output formatting: putting lines between namespace declarations

    - by devoured elysium
    I'm making some experiments with Visual Studio's CodeModel. I tried creating a file with two namespaces in there through VS's Code Model: CodeModel codeModel = projItem.ContainingProject.CodeModel; codeModel.AddNamespace("Namespaces.FirstNamespace", "namespacestest.cs"); codeModel.AddNamespace("Namespaces.SecondNamespace", "namespacestest.cs"); the output of such code is: //file namespacestest.cs namespace Namespaces.FirstNamespace { } namespace Namespaces.SecondNamespace { } Which is almost what I'm looking for. The only catch here is that I'd like to control the spacing: having at least one line between the first and the second namespace. Does by chance anyone know of a way of achieving this? This is what I want: //file namespacestest.cs namespace Namespaces.FirstNamespace { } namespace Namespaces.SecondNamespace { } Thanks

  • Specify only the second parameter in a javascript function

    - by Ben McCormack
    The spec for the jQuery ajax.error function is: error(XMLHttpRequest, textStatus, errorThrown)Function I'm trying to catch the error and display the textStatus, but I can't figure out how to specify only the textStatus without having to put in a variable name for XMLHttpRequest and errorThrown. My code currently looks like this: $.ajax({ type: "POST", contentType: "application/json; charset=utf-8", url: hbAddressValidation.webServiceUrl, data: this.jsonRequest, dataType: "json", timeout: 5, success: function (msgd) { //... }, error: function (a,textStatus,b) { $("#txtAjaxError").val("There was an error in the AJAX call: " + textStatus); } }); You can see in my code that I'm putting variables a and b as placeholders for the first and last variables in the error function. I know that in my success function, I'm only providing one parameter and it works fine, but in that case data is the first parameter. In the case of error, textStatus is the second parameter, but that's the only one I want to specify. Is this possible?

  • how do i use a .dat file as a model for an entity in minecraft?

    - by user1835502
    the entity does not have to do anything, just stand there like a statue, or it doesn't have to be an entity at all, just so the .dat file renders in minecraft i saw this http://pastebin.com/jP4diLJ9 in a java file that came with a .exe, and in the .exe you can choose one of the .dat files and it will show you it as a model, i also asked on minecraft forums and someone said it was possible but i have no idea how maybe has something to do with this try { FileOutputStream fileoutputstream = new FileOutputStream("./Models/"+id+".dat"); fileoutputstream.write(b, 0, b.length); fileoutputstream.close(); } catch(Throwable _ex) {} or if(i 0) {//grabs all models System.out.println("Sending request for Model: "+i); addRequest( 7, i); byte b[] = pack.unpack(download().buffer); if(pack.unpacked) { savemodel(i,b); System.out.println("Model Saved"); }else{ System.out.println("Model Grabbing Complete"); break;

  • eclipse: calling organizeimports programmatcally

    - by Stefan Roka
    Hi, I'm trying to execute 'OrganizeImports' programmatically on files that I'm editing programmatically. My code looks like this: final ICommandService cmdService = (ICommandService)PlatformUI.getWorkbench().getService (ICommandService.class); if (cmdService != null) { final Command cmd = cmdService.getCommand(IJavaEditorActionDefinitionIds.ORGANIZE_IMPORTS); final ExecutionEvent execEvt = new ExecutionEvent(cmd, Collections.EMPTY_MAP, compileationUnit, null); PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage(); ResourcesPlugin.getWorkspace(). Display.getDefault().syncExec(new Runnable() { @Override public void run() { try { //cmd.executeWithChecks(execEvt); cmd.execute(execEvt); } catch (Exception e) { getLogger().severe("organize imports failed: " + e.getMessage()); } } My problem is that OrganizeImportsAction executes on the current selection which is not the same as the compilation unit I'm editing. I would like to set the selection programmatically on the compilation unit but I don't know how to do that. Or maybe there is another way to trigger OrganizeImports. thanks, stefan

  • multiple FileSystemWatchers to monitor files on local system?

    - by Jason Crowes
    We're writing a text editor like tool for our internal accounting package system that has actions that can be done by our own Xml language specs. These macro commands are specified in Xml files and we need the ability to monitor if files openned have bean modified externally. The only problem is that there maybe 20-30 files with different paths openned at any one time. Would it be good to use multiple FileSystemWatchers for this scenario? Or would it be better to monitor the root drive and catch specific events that match an open file in the editor (though lots of events could be raised). Some are local drives (C,D,E) others are their network drives (U,X,G,H). Files are quite chunky too about 300-400Kb.

  • Problem with access to control properties in Multibox

    - by greatromul
    I used multibox-component to create lightbox-similar div. But I faced problem. I placed textbox with id ‘tbx_position’ in that div. I entered some symbols in textbox and then tried to read value via javascript-function (it had to alert document.getElementById(‘tbx_position’).value). Every time that value was empty. There is example of it. Furthermore, if I place in the div asp:Button, server OnClick-eventhandler doesn’t catch fire. Is any idea, what’s reason? Thanks.

  • Java session facade not being found via InitialContext lookups

    - by Hugh Buchanan
    I have a project that is Java EE 5 running on Glassfish. The IDE is Netbeans 6.7.1. We periodically have a very annoying problem with new session facades not being located via InitialContext: javax.naming.NameNotFoundException: No object bound to name java:comp/env/GlobalConfigEntityFacadeLocal In my class (within the same EJB container), I can use the other session facades just fine. This sort of problem happens periodically, and a mixture of clean&build and deleting the build-impl.xml files from nbproject sometimes resolve this. We are not using ejb-jar.xml (stopped using that over a year ago, it is now an empty The code that is calling this is very straight forward: GlobalConfigEntityFacadeLocal globalConfigEntityFacade = null; try { InitialContext ic = new InitialContext(); globalConfigEntityFacade = (GlobalConfigEntityFacadeLocal) ic.lookup("java:comp/env/GlobalConfigEntityFacadeLocal"); ... } catch ( ... ) {} Any advice would be appreciated!!!! Cheers

  • How do I use Criteria to make a join on a date field (in DB2) based on the year.

    - by HtmlTableGuru
    I have a java.util.Date field in my Object. I would like to use Criteria to select all rows that have a date field with a given year. The SQL would look like the following: SELECT * FROM GAME GM WHERE YEAR(GM.GAME_DATE) = 2010 How can I use Criteria to accomplish this? Thanks in advance. public Collection<Game> getGamesByDate(Date date){ Collection<Game> games = null; try { session.beginTransaction(); Criteria criteria = session.createCriteria(Game.class); criteria .... ... ... games = criteria.list(); } catch (HibernateException e) { e.printStackTrace(); } return games; }

  • jQuery validation plugin doens't work for me

    - by Idsa
    I have the following code to enable validation work: $(document).ready(function() { $("#eventForm").validate({ rules: { startDate: "required", startTime: "required", endDate: { required: function (element) { var endTimeValue = $('#endTime').val(); return (endTimeValue != null && endTimeValue != ''); } }, endTime: { required: function (element) { var endDateValue = $('#endDate').val(); return (endDateValue != null && endDateValue != ''); } } }, messages: { startDate: "Please enter event local start date", startTime: "Please enter event local start time" }, errorPlacement: function (error, element) { error.appendTo(element.parent().next()); }, submitHandler: function (form) { var options = { dataType: 'json', success: eventCreationSuccess, error: eventCreationError }; alert('submit'); //$(form).ajaxSubmit(options); } }); }); But validation plugin doesn't catch submit - default submit is executed. jQuery and validation plugin scripts are imported.

  • Client-side session timeout redirect in ASP.Net

    - by Mercury821
    I want to build a way to automatically redirect users to Timeout.aspx when their session expires due to inactivity. My application uses forms authentication and relies heavily on update panels within the same aspx page for user interaction, so I don't want to simply redirect after a page-level timer expires. For the same reason, I can't use '<meta http-equiv="refresh"/>' What I want to do is create a simple ajax web service with a method called IsSessionTimedOut(), that simply returns a boolean. I will use a javascript timer to periodically call the method, and if it returns true, then redirect to Timeout.aspx. However, I don't want calling this method to reset the session timeout timer, or the session would never time out because of the service call. Is there a clean way to avoid this catch-22? Hopefully there is an easy solution that has so far eluded me.

  • Error using MVCContrib TestHelper

    - by Brian McCord
    While trying to implement the second answer to a previous question, I am receiving an error. I have implemented the methods just as the post shows, and the first three work properly. The fourth one (HomeController_Delete_Action_Handler_Should_Redirect_If_Model_Successfully_Delete) gives this error: Could not find a parameter named 'controller' in the result's Values collection. If I change the code to: actual .AssertActionRedirect() .ToAction("Index"); it works properly, but I don't like the "magic string" in there and prefer to use the lambda method that the other poster used. My controller method looks like this: [HttpPost] public ActionResult Delete(State model) { try { if( model == null ) { return View( model ); } _stateService.Delete( model ); return RedirectToAction("Index"); } catch { return View( model ); } } What am I doing wrong?

  • Show friendly message on ASP.NET Ajax error

    - by balexandre
    You all know how annoying is this: I do have a log system and the correct error is well explicit there, but I want to give a better message to the user. I keep trying several ways but I'm using Telerik components and well jQuery and I ended up using both ASP.NET Ajax methods and jQuery, so I use function pageLoad() { try { var manager = Sys.WebForms.PageRequestManager.getInstance(); manager.add_endRequest(endRequest); manager.add_beginRequest(OnBeginRequest); manager } catch (err) { alert(err); } } as well $(document).ready(function() { ... } that alert(err) is never fired even upon OnClick events what's the best approach to avoid this message errors and provide a cleaner way? all this happens in <asp:UpdatePanel> as I use that when I didn't know better (3 years ago!) and I really don't want to mess up and build all again from scratch :( Any help is greatly appreciated Updated with more error windows after volpav solution

  • How to retrieve XML attribute for custom control

    - by David
    I've created a combo box control with a edittext and spinner. I'm trying to let the android:prompt attribute be passed onto the spinner, which means I need to catch it in the constructor which passes my the AttributeSet and set it on the spinner. I can't figure out how to get the value of the prompt. I'm trying, int[] ra = { android.R.attr.prompt }; TypedArray ta = context.getTheme().obtainStyledAttributes(ra); int id = ta.getResourceId(0, 0); I get back 0, which means it didn't find the attribute. I also did a ta.count() which returned 0. So I'm not getting anything back. My XML simply defines an android:prompt value. Thanks
