  • How to use SerialPort SerialDataReceived help

    - by devnet247
    Hi Not sure how to handle SerialPort DataReceived. Scenario I have an application that communicate with a device and this device returns a status .This happens in different stages EG public enum ActionState { Started, InProgress, Completed etc... } Now if I were to use the DataReceivedEventHandler how can I tell what Method is executing? eg Action1 or Action2 etc...? I also want to include some sort of timeout when getting back stuff from device. Any example or advice? public ActionState Action1 { serialPort.write(myData); string result=serialPort.ReadExisting()); //convertTo ActionState and return return ConvertToActionState(result); } public ActionState Action2 { serialPort.write(myData); string result=serialPort.ReadExisting()); //convertTo ActionState and return return ConvertToActionState(result); } private void port_DataReceived(object sender, SerialDataReceivedEventArgs e) { //How can I use this to detect which method is firing and set the actionState Enum accordingly? } private ActionState(string result) { if(result==1) return ActionState.Started; else if (result==2) return ActionState.Completed etc... }

  • Average of two strings in alphabetical order

    - by Bemmu
    Suppose you take the strings 'a' and 'z' and list all the strings that come between them in alphabetical order: ['a','b','c' ... 'x','y','z']. Take the midpoint of this list and you find 'm'. So this is kind of like taking an average of those two strings. You could extend it to strings with more than one character, for example the midpoint between 'aa' and 'zz' would be found in the middle of the list ['aa', 'ab', 'ac' ... 'zx', 'zy', 'zz']. Might there be a Python method somewhere that does this? If not, even knowing the name of the algorithm would help. I began making my own routine that simply goes through both strings and finds midpoint of the first differing letter, which seemed to work great in that 'aa' and 'az' midpoint was 'am', but then it fails on 'cat', 'doggie' midpoint which it thinks is 'c'. Rather than invent a method I thought it better to ask. I tried Googling for "binary search string midpoint" etc. but without knowing the name of what I am trying to do here I had little luck.

  • Proper DateTime Format for a Web Service

    - by user48408
    I have a webservice with a method which is called via a xmlhttprequest object in my javascript. The method accepts a datetime parameter which is subsequently converted to a string and run against the database to perform a calculation. I get the value from m_txtDateAdd and send off the xmlHttprequest <asp:textbox id=m_txtDateAdd tabIndex=4 runat="server" Width="96px" Text="<%# Today %>"> </asp:textbox> which has a validator attacted to it <asp:CustomValidator id="m_DateAddValidator" runat="server" ErrorMessage="Please Enter a Valid Date" ControlToValidate="m_txtDateAdd">&#x25CF;</asp:CustomValidator> My webmethod looks something like this [WebMethod] public decimal GetTotalCost(DateTime transactionDate) { String sqlDateString = transactionDate.Year+"/"+transactionDate.Month+"/"+transactionDate.Day; I use sqlDateString as part of the commandtext i send off to the database. Its a legacy application and its inline sql so I don't have the freedom to set up a stored procedure and create and assign parameters in my code behind. This works 90% of the time. The webservice is called on the onchange event of m_txtDateAdd. Every now and again the response i get from the server is System.ArgumentException: Cannot convert 25/06/2009 to System.DateTime. System.ArgumentException: Cannot convert 25/06/2009 to System.DateTime. Parameter name: type --- System.FormatException: String was not recognized as a valid DateTime. at System.DateTimeParse.Parse(String s, DateTimeFormatInfo dtfi, DateTimeStyles styles) at System.DateTime.Parse(String s, IFormatProvider provider) at System.Convert.ToDateTime(String value, IFormatProvider provider) at System.String.System.IConvertible.ToDateTime(IFormatProvider provider) at System.Convert.ChangeType(Object value, Type conversionType, IFormatProvider provider) at System.Web.Services.Protocols.ScalarFormatter.FromString(String value, Type type) --- End of inner exception stack trace --- at System.Web.Services.Protocols.ScalarFormatter.FromString(String value, Type type) at System.Web.Services.Protocols.ValueCollectionParameterReader.Read(NameValueCollection collection) at System.Web.Services.Protocols.HtmlFormParameterReader.Read(HttpRequest request) at System.Web.Services.Protocols.HttpServerProtocol.ReadParameters() at System.Web.Services.Protocols.WebServiceHandler.CoreProcessRequest()

  • Understanding floating point problems

    - by Maxim Gershkovich
    Could someone here please help me understand how to determine when floating point limitations will cause errors in your calculations. For example the following code. CalculateTotalTax = function (TaxRate, TaxFreePrice) { return ((parseFloat(TaxFreePrice) / 100) * parseFloat(TaxRate)).toFixed(4); }; I have been unable to input any two values that have caused for me an incorrect result for this method. If I remove the toFixed(4) I can infact see where the calculations start to lose accuracy (somewhere around the 6th decimal place). Having said that though, my understanding of floats is that even small numbers can sometimes fail to be represented or have I misunderstood and can 4 decimal places (for example) always be represented accurately. MSDN explains floats as such... This means they cannot hold an exact representation of any quantity that is not a binary fraction (of the form k / (2 ^ n) where k and n are integers) Now I assume this applies to all floats (inlcuding those used in javascript). Fundamentally my question boils down to this. How can one determine if any specific method will be vulnerable to errors in floating point operations, at what precision will those errors materialize and what inputs will be required to produce those errors? Hopefully what I am asking makes sense.

  • Regarding Toplink Fetching Policy

    - by Chandu
    Hi, I'm working for a Swing Project and the technologies used are netbeans with Toplink essentials, mysql. The Problem I'm facing is the entity object dosn't get updated after insertions take place while calling a getter collection of the foreign key property. Ex: I have 2 tables Table1,Table2. I have sno column, id column as a primary key in Table1 & is Foreign Key in Table2. Through find method I just get the particular sno object(existed in table 1) set some values persisted to table2 & committed the transaction. When I select the same sno object through find method & gets its collection from Table2 through the getTable2Collection() of the bean(as it is already created in bean by toplink essential) I'm unable to get the latest added record except that all other records of it are displayed. After I close the application & opening it then the new record gets reflected while calling the same sno through the above process. I came to know that this is a kind of lazy fetching and there should be some way of fetch policy to be changed to make the entity object get updated with the changes. So Please help me in this regard. Regards, Chandu

  • managed beans as managed properties

    - by Sean
    I am using JSF 1.1 on WebSphere 6.1. I am building search functionality within an application and am having some issues. I've stripped out the extras, and have left myself with the following: 4 managed beans: SearchController - Controller bean, session scope SearchResults - session scope (store the results) ProductSearch - session scope (store the search conditions) ResultsBacking - Backing bean for DataTable, used to determine which row was clicked, request scope The SearchController bean has, as managed properties, the other 3. All except ResultsBacking are session scoped. If there is only 1 item in the search results, I want to bring up that record directly. I call setFirst(0) for the data table in the ResultsBacking method (I want to use the existing method that handle which item was clicked, so this is called right after the setFirst). When I go to do another search, I get an IllegalArgumentException when calling getRowData in the data table. According to the api, this is thrown 'if now(sic) row data is available at the currently specified row index'. I'm confused as to why this happens. It works the first time but not the second. Do I need to remove the ResultsBacking on a new search to get rid of the old state?

  • Modify coverflow component ,add backview ?

    - by hib
    Hi all , I am developing an iPhone application in which I needs to implement a Coverflow component. I got a good library from here It is working nicely . Now I want to show a different back view with 6 buttons when a user double taps on the image in the coverflow . For that the tapkulibrary author has implemented a delegate method called which is : - (void) coverflowView:(TKCoverflowView*)coverflowView coverAtIndexWasDoubleTapped:(int)index{ TKCoverView *cover = [coverflowView coverAtIndex:index]; //if(cover == nil) return; // [UIView beginAnimations:nil context:nil]; // [UIView setAnimationDuration:1]; // [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:cover cache:YES]; // [UIView commitAnimations]; *********************MY BACK View ******************************* UIView *c; NSArray *array = [[NSBundle mainBundle] loadNibNamed:@"TestMine" owner:nil options:nil]; c = [array objectAtIndex:0]; [cover addSubview:c]; [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:1.0]; [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:cover cache:YES]; [UIView setAnimationDuration:1.0]; CGAffineTransform transform = CGAffineTransformMakeScale(1.2, 1.2); cover.transform = transform; [UIView commitAnimations]; NSLog(@"Index: %d",index); } I am not much aware about the drawing code used in this example my back view is not working perfectly . So can anyone modify me this method or code to push my back view when double tapping the image and again double tapping shows the real image again . I need help .

  • UIWebViewDelegate returns different error message on iPod Touch 2G and 3G

    - by lostInTransit
    Hi I have an app developed using SDK 3.0. My view has a UIWebView whose delegate is the viewcontroller. I want to show an error message when the webview does not load (in case the touch goes out of wifi range or wifi is turned off) I override this method to show an alert - (void)webView:(UIWebView *)wbView didFailLoadWithError:(NSError *)error But this caused an issue when some links were clicked on the webview. The page loaded but if some images from the previous page were not loaded, the method call was triggered. Testing on an iPod Touch 3G, the NSError's userInfo has the localized description as no Internet connection if load fails due to no internet connection. But this only seems to be true for an iPod Touch 3G. 2G shows a different message (I got to know from some beta testers. They aren't very technical so can't tell them to get me the logs or anything.) Can anyone with an iPod Touch 2G tell me the values for the NSError userInfo? Or better still, did anyone else face this issue? How did you resolve it? Thanks.

  • send Image from J2ME to SERVLET

    - by Akash
    Hi, I want to send Image from J2ME to SERVLET. I am able to convert image into Byte Array, and send by Http POST. I have coded as : - From Mobile : conn = (HttpConnection)Connector.open(url,Connector.READ_WRITE,true); conn.setRequestMethod(HttpConnection.POST); conn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded"); os.write(bytes, 0, bytes.length);//bytes = byte array of image At servlet : String line; BufferedReader r1 = new BufferedReader(new InputStreamReader(in)); while ((line = r1.readLine()) != null) { System.out.println("line=" + line); buf.append(line); } String s = buf.toString(); byte[] img_byte = s.getBytes(); Now d problem I found is, when I send Bytes from Mob App, some bytes are LOST , whose value is 0A and 0D-Hex ... Exactly, Cr- Carriage Return & Lf- Line Feed... It means, POST method OR readLine() not able to accept 0A & 0D value... And so I come to know that, LOST bytes are 0A and 0D occurrence in image's byte array.... Any one have any idea, how to do this, or how to use any another method..... Thanks -Akash

  • How do I pass a callback function to sqlite3_exec on iOS 5.1?

    - by John Doh
    I am new to both xcode/iOS/Objective-C and sqlite. I am trying to teach myself the basics - and I would like to use the sqlite3 wrapper "sqlite3_exec" for a select query. For some reason, I can't find a simple example anywhere of someone doing this. Basically, the method has a parameter (the third one) for a callback function: int sqlite3_exec( sqlite3*, /* An open database */ const char *sql, /* SQL to be evaluated */ int (*callback)(void*,int,char**,char**), /* Callback function */ void *, /* 1st argument to callback */ char **errmsg /* Error msg written here */ ); That's fine. I'm no stranger to callbacks. However, I just can't seem to get the syntax down right. I took over one of the view controllers in my iPad (iOS 5.1) xcode (4.3) project, and made the changes shown below: #import "SecondViewController.h" #import "sqlite3.h" #import "AppState.h" @interface SecondViewController () @end @implementation SecondViewController - (int)myCallback:(void *)a_parm argc:(int)argc argv:(char **)argv column:(char **)column { return 0; } - (void)viewDidLoad { [super viewDidLoad]; // Do any additional setup after loading the view, typically from a nib. //grab questionnaire names char *sql = "select * from QST2Main order by [Name]"; char *err = nil; sqlite3 *db = [[AppState sharedManager] getgCn]; sqlite3_exec(db, sql, myCallback, nil, &err); } Essentially, I want to run a query when this view first loads, to store some data for later use. But, XCode doesn't like the "myCallback" usage at the bottom there. It says: Undeclared Use of Identifier 'myCallback.' That method is declared in the header file, and I've even tried making it static. Nothing seems to make this error go away. I know I must be doing something fundamentally wrong here, but for the life of me I can't figure out what - I can't even find other code samples in this area that could help me figure out what I'm missing. Many thanks!

  • Access and modify attributes/objects which are not part of the form backing bean

    - by spa
    I use Spring MVC (via Spring Roo) to build a small web application for administering persons. In the page for creating a person the bean Person is used as form backing object (key "person" in the model map). <form:form action="${form_url}" method="POST" modelAttribute="person"> I would like to add some attributes to the model map which can be altered by the user in the creation form. Basically, I try to add a Boolean, so that I can control which page is displayed next after the user presses the submit button. I try to modify the Boolean (key "myBoolean" in the model map) using a simple checkbox: <form:checkbox id="_myboolean_id" path="myBoolean"/> However, as I am new to Spring MVC I have some difficulties here. The Boolean object is not an attribute of the form backing object. So if I try to access it the following exception is thrown (of course): Invalid property 'myBoolean' of bean class [de.cm.model.Person]: Bean property 'myBoolean' is not readable or has an invalid getter method: Does the return type of the getter match the parameter type of the setter? Is there are way to access a value of the model map directly? The only solution I can imagine right now is a kind of wrapper object around the class Person and my additional attributes which is used as a new form backing object. However, this is more work for a IMHO simple task. Do you have a better solution?

  • Using Word COM objects in .NET, InlineShapes not copied from template to document

    - by Keith
    Using .NET and the Word Interop I am programmatically creating a new Word doc from a template (.dot) file. There are a few ways to do this but I've chosen to use the AttachedTemplate property, as such: Dim oWord As New Word.Application() oWord.Visible = False Dim oDocuments As Word.Documents = oWord.Documents Dim oDoc As Word.Document = oDocuments.Add() oDoc.AttachedTemplate = sTemplatePath oDoc.UpdateStyles() (I'm choosing the AttachedTemplate means of doing this over the Documents.Add() method because of a memory leak issue I discovered when using Documents.Add() to open from templates.) This works fine EXCEPT when there is an image (represented as an InlineShape) in the template footer. In that case the image does not appear in the resulting document. Specifically the image should appear in the oDoc.Sections.Item(1).Footers.Item(WdHeaderFooterIndex.wdHeaderFooterPrimary).Range.InlineShapes collection but it does not. This is not a problem when using Documents.Add(), however as I said that method is not an option for me. Is there an extra step I have to take to get the images from the template? I already discovered that when using AttachedTemplate I have to explicitly call UpdateStyles() (as you can see in my code snippet) to apply the template styles to the document, whereas that is done automatically when using Documents.Add(). Or maybe there's some crazy workaround? Your help is much appreciated! :)

  • How can I connect to server using SSL(secure socket layer) on .NET Compact Framework

    - by net
    Hello. I want to change .NET framework v3.5 to .NET compact framework v3.5. But I can't change SSL Stream class to compact framework version. For resolving this problem, I already read some article and msdn library. http://blogs.msdn.com/cgarcia/archive/2009/08/21/enable-ssl-for-managed-socket-on-windows-mobile.aspx http://blogs.msdn.com/cgarcia/archive/2009/08/22/getting-a-managed-socket-to-talk-ssl.aspx http://msdn.microsoft.com/en-us/library/aa916117.aspx but I got an error that is "Unkown error 0x0ffffff", when invoking 'socket.connect(endPoint)' method based on thease article. In order to find the proper method, I try to use TcpClient class. but i can't solve this problem. When I try to connect to server on .NET compact framework, TcpClient class didn't work(Smart Device project and windows ce). As you can see below, I've got the error. In other hand, this code is work on .NET framework(C# console project). I can't understand why this socket can not access to server. Thanks for reading my question.

  • Should business objects be able to create their own DTOs?

    - by Sam
    Suppose I have the following class: class Camera { public Camera( double exposure, double brightness, double contrast, RegionOfInterest regionOfInterest) { this.exposure = exposure; this.brightness = brightness; this.contrast = contrast; this.regionOfInterest = regionOfInterest; } public void ConfigureAcquisitionFifo(IAcquisitionFifo acquisitionFifo) { // do stuff to the acquisition FIFO } readonly double exposure; readonly double brightness; readonly double contrast; readonly RegionOfInterest regionOfInterest; } ... and a DTO to transport the camera info across a service boundary (WCF), say, for viewing in a WinForms/WPF/Web app: using System.Runtime.Serialization; [DataContract] public class CameraData { [DataMember] public double Exposure { get; set; } [DataMember] public double Brightness { get; set; } [DataMember] public double Contrast { get; set; } [DataMember] public RegionOfInterestData RegionOfInterest { get; set; } } Now I can add a method to Camera to expose its data: class Camera { // blah blah public CameraData ToData() { var regionOfInterestData = regionOfInterest.ToData(); return new CameraData() { Exposure = exposure, Brightness = brightness, Contrast = contrast, RegionOfInterestData = regionOfInterestData }; } } or, I can create a method that requires a special IReporter to be passed in for the Camera to expose its data to. This removes the dependency on the Contracts layer (Camera no longer has to know about CameraData): class Camera { // beep beep I'm a jeep public void ExposeToReporter(IReporter reporter) { reporter.GetCameraInfo(exposure, brightness, contrast, regionOfInterest); } } So which should I do? I prefer the second, but it requires the IReporter to have a CameraData field (which gets changed by GetCameraInfo()), which feels weird. Also, if there is any even better solution, please share with me! I'm still an object-oriented newb.

  • Add Zend_Navigation to the View with old legacy bootstrap

    - by Grant Collins
    Hi, I've been struggling with Zend_Navigation all weekend, and now I have another problem, which I believe has been the cause of a lot of my issues. I am trying to add Zend_Navigation to a legacy 1.7.6 Zend Framework application, i've updated the Zend Library to 1.9.0 and updated the bootstrap to allow this library update. The problem is that I don't know how, and the examples show the new bootstrap method of how to add the Navigation object to the view, I've tried this: //initialise the application layouts with the MVC helpers $layout = Zend_Layout::startMvc(array('layoutPath' => '../application/layouts')); $view = $layout->getView(); $configNav = new Zend_Config_Xml('../application/config/navigation.xml', 'navigation'); $navigation = new Zend_Navigation($configNav); $view->navigation($navigation); $viewRenderer = new Zend_Controller_Action_Helper_ViewRenderer(); $viewRenderer->setView($view); This seems to run through fine, but when I go to use the breadcrumb view helper in my layout, it errors with: Strict Standards: Creating default object from empty value in C:\www\moobia\development\website\application\modules\employers\controllers\IndexController.php on line 27 This is caused by the following code in the init() function of my controller. $uri = $this->_request->getPathInfo(); $activeNav = $this->view->navigation()->findByUri($uri); <- this is null when called $activeNav->active = true; I believe it's because the Zend_Navigation object is not in the view. I would look at migrating the bootstrap to the current method, but at present I am running out of time for a release. Thanks, Grant

  • Debugging Maya plug-ins: can't get output or debugger to engage

    - by brainjam
    I'm not a total beginner at Maya, but this is my first time trying to write a plug-in for it. I've downloaded the 30-day eval version of Maya2011 (32bit version on 64bit Windows 7), and have tried building a couple of plug-ins with VC 2008 Express. The first one is helloWorldCmd from the sample directory ..\devkit\plug-ins, and it basically doesn't work until you convert the line cout<<"Hello World"<<endl; to cerr<<"Hello World"<<endl;, but I can live with that. The second one is the SelectRingContext2 example from David Gould's book. The plug-in works as advertised, but I cannot get any debugging output from it. I've tried putting cout, cerr,printf, and MGlobal::displayInfo into the doIt() method, and can't get a peep. I also haven't figured out how to run the plug-in in a debugger. I'm afraid I'm missing something easy but slightly obscure, like a flag somewhere. Anybody out there have any hints? Edit: Turns out the action is happening in the redoIt() method. So I can get MGlobal::displayInfo and cerr producing output. Still don't know why cout and printf don't work, and I'm not sure how to run in the debugger. When I run maya -d (which some of the online advice says I should do) it just shows the output window but never loads the rest.

  • Dilemma of Sending a Byte Array from JavaScript to COM.

    - by Voulnet
    Hello there, I'm having a bit of a problem because neither Javascript nor ActiveX (written in C++) are behaving like good little children. All I'm asking them to do is for Javascript to send a byte array and for the ActiveX to receive the byte array correctly in order to do more computation. This is how I declared my byte array in JS, and I verified it inside JS: var arr = new Array(0x00, 0xA4, 0x04, 0x00, 0x10,0xA0, 0x00, 00, 00, 0x18, 0x30, 0x03, 0x01, 00, 00, 00, 00, 00, 00, 00, 00); Javascript sends this array as an argument to an ActiveX method. Here is the tricky part; I want the ActiveX method to receive the byte array as a SAFEARRAY or VARIANT, but I can't get it to work for the life of me. I tried debugging and seeing the contents received inside the ActiveX as both SAFEARRAY or VARIANT, but to no avail. Here is the IDL segment: [id(7), helpstring("NEW Sends APDU to Card and Reads the Response")] HRESULT NewSendAPDU( [in] VARIANT pAPDU, [out, retval]VARIANT* pAPDUResponse); Any help is greatly appreciated. Thanks in advance!

  • Show NotifyIcon Context Menu and Control Its Position?

    - by Shawn O'Hern
    I'm trying to show a context menu when I left-click a NotifyIcon. Just calling NotifyIcon.ContextMenuStrip.Show() doesn't work very well. A solution has been posted here before that calls a secret method using Reflection: Dim mi As System.Reflection.MethodInfo = GetType(NotifyIcon).GetMethod("ShowContextMenu", Reflection.BindingFlags.Instance Or Reflection.BindingFlags.NonPublic) mi.Invoke(Icon, Nothing) This works great, except that I also need to control where the menu is shown. I want to wait for the SystemInformation.DoubleClickTime to elapse between receiving the NotifyIcon.MouseUp event and displaying the menu, so that I can handle single-clicks and double-clicks separately. But invoking the ShowContextMenu method displays the menu at the current mouse position when ShowContextMenu is called, not when the icon was actually clicked. Which means that if the mouse moved during the DoubleClickTime, the menu will be displayed in a different part of the screen. So if I can control where the menu is shown, I can just save the mouse coordinates when I receive the MouseUp event, and then I can ensure that the menu is displayed near the icon. Is there a way to do this? Thanks in advance.

  • Spinner in Android crashing when visibilty changes while handling OnClick in a button

    - by Dave George
    I have a spinner in UI, which I want to hide when I handle onClick method for a button. But the application is crashing all the time. Is it that I can't use the setVisibility(View.Gone) on spinners (it is not written anywhere). If I comment it out, then application run fine. I am getting NullPointerException and I am using RelativeLayout. Also, can I do this: public void onItemSelected(AdapterView<?> arg0, View view, int pos, long arg3) { // TODO Auto-generated method stub Toast.makeText(SpinnerActivity.this,selected , Toast.LENGTH_SHORT).show(); spinner.setVisibility(View.GONE); } } Spinner code fore reference: itemsCity=getResources().getStringArray(R.array.cities_array); ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource( this, R.array.cities_array, android.R.layout.simple_spinner_item); adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); spinnerCity.setAdapter(adapter); And here is Button code: private class BtClickListner implements View.OnClickListener{ @Override public void onClick(View v) { essEditText.setVisibility(View.GONE); spinnerCity.setEnabled(false);// Getting exception here // Also tried spinnerCity.setVisibility(View.GONE);// Exception SameBt.setVisibility(View.GONE);// This is same button for which I am handliing event, but it allows me to change tis property at run time. }

  • Red Box is not working

    - by palani
    Hi , I have install the Red box plugin by using the following command script/plugin install svn://rubyforge.org/var/svn/ambroseplugins/redbox . It installed successfully. and again ran the following command the following location /myapp/vendor/plugin/redbox/rake update_scripts . It shows me the following output (in /myapp/vendor/plugins/redbox) rake aborted! private method `copy' called for File:Class /home/myapp/vendor/plugins/redbox/Rakefile:28 (See full trace by running task with --trace) I don't know How to solve this ... Then i understand that "rake update_scripts" copying the Js and Css file only. so i manually copied the Redbox.js & redbox.css files into the respective places under /public folder I include the follwoing into my application.html.erb <%= stylesheet_link_tag 'redbox' % <%= javascript_include_tag :defaults % <%= javascript_include_tag 'redbox' % It included in the page successfully. The following is my view code : <%= link_to_remote_redbox('Red_box', :url = {:action= 'log'} ,:method ='get') % The popup box doesn't appear. I have no clue what is the exact error. Is that any Jquery clash? Please help me

  • Windows Service Conundrum

    - by Paul Johnson
    All, I have a Custom object which I have written using VB.NET (.net 2.0). The object instantiates its own threading.timer object and carries out a number of background process including periodic interrogation of an oracle database and delivery of emails via smtp according to data detected in the database. The following is the code implemented in the windows service class Public Class IncidentManagerService 'Fakes Private _fakeRepoFactory As IRepoFactory Private _incidentRepo As FakeIncidentRepo Private _incidentDefinitionRepo As FakeIncidentDefinitionRepo Private _incManager As IncidentManager.Session 'Real Private _started As Boolean = False Private _repoFactory As New NHibernateRepoFactory Private _psalertsEventRepo As IPsalertsEventRepo = _repoFactory.GetPsalertsEventRepo() Protected Overrides Sub OnStart(ByVal args() As String) ' Add code here to start your service. This method should set things ' in motion so your service can do its work. If Not _started Then Startup() _started = True End If End Sub Protected Overrides Sub OnStop() 'Tear down class variables in order to ensure the service stops cleanly _incManager.Dispose() _incidentDefinitionRepo = Nothing _incidentRepo = Nothing _fakeRepoFactory = Nothing _repoFactory = Nothing End Sub Private Sub Startup() Dim incidents As IList(Of Incident) = Nothing Dim incidentFactory As New IncidentFactory incidents = IncidentFactory.GetTwoFakeIncidents _repoFactory = New NHibernateRepoFactory _fakeRepoFactory = New FakeRepoFactory(incidents) _incidentRepo = _fakeRepoFactory.GetIncidentRepo _incidentDefinitionRepo = _fakeRepoFactory.GetIncidentDefinitionRepo 'Start an incident manager session _incManager = New IncidentManager.Session(_incidentRepo, _incidentDefinitionRepo, _psalertsEventRepo) _incManager.Start() End Sub End Class After a little bit of experimentation I arrived at the above code in the OnStart method. All functionality passed testing when deployed from VS2005 on my development PC, however when deployed on a true target machine, the service would not start and responds with the following message: "The service on local computer started and then stopped..." Am I going about this the correct way? If not how can I best implement my incident manager within the confines of the Windows Service class. It seems pointless to implement a timer for the incidentmanager because this already implements its own timer... Any assistance much appreciated. Kind Regards Paul J.

  • Append a dynamically changing watermark to a PDF in SharePoint

    - by ccomet
    This is primarily a question of possibilities more than instructions. I'm a programming consultant working on a WSS project site system for my client. We have a document library in which files are uploaded to go through a complex approval process. With multiple stages in this process, we have an extra field which dictates what the current status of the document is. Now, my client has become enamored with the idea of PDF watermarking. He wants the document (which is already a PDF) to be affixed with a watermark corresponding to the current status, such that with each stage of the approval process the watermark will change. One method, the traditional method for PDF watermarking, of accomplishing this is to have one "clean" copy of the document somewhere hidden on the site, and create a new PDF from it that has the watermark at each stage of the approval process. Since the filename will never change, this new PDF can be uploaded continually to a public library, always overwriting the old version and simulating a "dynamically changing watermark". However, in the various stages there will also be people uploading clean copies with corrections and suggestions, nevermind the complex nature of juggling around two libraries and the fact we double the number of files stored. My client and I agree that this is not a practical path to choose. What we would like to do is be able to "modify" the watermark in a PDF, so that we only have to keep one copy of the file. Unfortunately, from what I've seen, in most cases when you make something like a watermark, which in its nature is supposed to be "unmodifyable", you won't be able to edit it later. So, is it possible to have a part of a PDF which cannot be changed by anyone who downloads the file, but can be changed as part of a workflow or other object model process? Thanks in advance!

  • Graph limitations - Should I use Decorator?

    - by Nick Wiggill
    I have a functional AdjacencyListGraph class that adheres to a defined interface GraphStructure. In order to layer limitations on this (eg. acyclic, non-null, unique vertex data etc.), I can see two possible routes, each making use of the GraphStructure interface: Create a single class ("ControlledGraph") that has a set of bitflags specifying various possible limitations. Handle all limitations in this class. Update the class if new limitation requirements become apparent. Use the decorator pattern (DI, essentially) to create a separate class implementation for each individual limitation that a client class may wish to use. The benefit here is that we are adhering to the Single Responsibility Principle. I would lean toward the latter, but by Jove!, I hate the decorator Pattern. It is the epitome of clutter, IMO. Truthfully it all depends on how many decorators might be applied in the worst case -- in mine so far, the count is seven (the number of discrete limitations I've recognised at this stage). The other problem with decorator is that I'm going to have to do interface method wrapping in every... single... decorator class. Bah. Which would you go for, if either? Or, if you can suggest some more elegant solution, that would be welcome. EDIT: It occurs to me that using the proposed ControlledGraph class with the strategy pattern may help here... some sort of template method / functors setup, with individual bits applying separate controls in the various graph-canonical interface methods. Or am I losing the plot?
