• Calculate total time between Dates in Hours and Minutes

  - by matthew parkes

  Hi I’m trying to resolve a problem using VB and I need some assistance. I’m very new to the language (1 week). The problem is I have created a user form to show how many hours and minutes has elapsed between two different times similar to a time sheet. The user form consists of two calendars, and under each calendar there are two text boxes; one box each to record the Hour and Minute they left and two further boxes to record the time they arrived back. I have used the code to minus the calendars together (e.g calendar in – calendar out) then times this by 24 to indicate the hours away. Then under the calendar out I have a text box for the user to type in the hour they left. Then I minus the 24 by the Hour out e.g. if it was 24 -15 it will appear 9 ( 9 hours of that day ) then I would add that to the figure they inserted in the text box Hour in (Return Time). e.g 14. Then I would add them to together e.g. 9 + 14 = 23 and have this displayed in another text box Total Hours. Therefore it would display 23 meaning 23 hours. I have then want to show another two text boxes to indicate minutes. One for Minutes Out then Minutes In. I have the problem to convert these minutes for instance if it is the out time is 15:50 and the in time the next day is at 15:55 it displays as 24 (in one text box) and 105 minutes (in the other text box). I would like the minutes added to the hour and have the balance of the remaining minutes in the minute text box. This should display 24 (in one text box) and 5 (in another text box). The ultimate aim is to get a result that shows a person was absent for a number of days, hours and minutes, eg, 2 days, 5 hours and 10 minutes. Any ideas on how I can modify my code to achieve this? Here’s my code. Please Help Dim number1 As Date Dim number2 As Date Dim number3 As Integer Dim number4 As Integer Dim Number5 As Integer Dim Number6 As Integer Dim answer As Integer Dim answer2 As Integer Dim answer3 As Integer Dim answer4 As Integer Dim answer5 As String number1 = DTPicker1 number2 = DTPicker2 number3 = Txthourout number4 = TxtHourin Number5 = TxtMinuteout Number6 = TxtMinuetIn answer = number2 - number1 answer2 = answer * 24 answer3 = answer2 - number3 answer4 = answer3 + number4 answer5 = Number5 + Number6 TextBox1.Text = answer4 TextBox2.Text = answer5 End Sub

• Why does my Spring Controller direct me to the wrong page?

  - by kc2001

  I am writing my first Spring 3.0.5 MVC app and am confused about why my controller mappings aren't doing what I expect. I have a VerifyPasswordController that is called after a user tries to log in by entering his name and password. // Called upon clicking "submit" from /login @RequestMapping(value = "/verifyPassword", method = RequestMethod.POST) @ModelAttribute("user") public String verifyPassword(User user, BindingResult result) { String email = user.getEmail(); String nextPage = CHOOSE_OPERATION_PAGE; // success case if (result.hasErrors()) { nextPage = LOGIN_PAGE; } else if (!passwordMatches(email, user.getPassword())) { nextPage = LOGIN_FAILURE_PAGE; } else { // success } return nextPage; } I can verify in the debugger that this method is being called, but afterwards, the verifyPassword page is displayed rather than the chooseOperation page. The console output of WebLogic seems to show that my mapping are correct: INFO : org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping - Mapped URL path [/chooseOperation] onto handler 'chooseOperationController' INFO : org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping - Mapped URL path [/chooseOperation.*] onto handler 'chooseOperationController' INFO : org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping - Mapped URL path [/chooseOperation/] onto handler 'chooseOperationController' Here is the ChooseOperationController: @Controller @SessionAttributes("leaveRequestForm") public class ChooseOperationController implements PageIfc, AttributeIfc { @RequestMapping(value = "/chooseOperation") @ModelAttribute("leaveRequestForm") public LeaveRequest setUpLeaveRequestForm( @RequestParam(NAME_ATTRIBUTE) String name) { LeaveRequest form = populateFormFromDatabase(name); return form; } // helper methods omited } I welcome any advice, particularly "generic" techniques for debugging such mapping problems. BTW, I've also tried to "redirect" to the desired page, but got the same result. servlet-context.xml: <?xml version="1.0" encoding="UTF-8"?> <beans:beans xmlns="http://www.springframework.org/schema/mvc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:beans="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation=" http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd"> <!-- DispatcherServlet Context: defines this servlet's request-processing infrastructure --> <!-- Enables the Spring MVC @Controller programming model --> <annotation-driven /> <!-- Handles HTTP GET requests for /resources/** by efficiently serving up static resources in the ${webappRoot}/resources directory --> <resources mapping="/resources/**" location="/resources/" /> <!-- Resolves views selected for rendering by @Controllers to .jsp resources in the /WEB-INF/views directory --> <beans:bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <beans:property name="prefix" value="/WEB-INF/views/" /> <beans:property name="suffix" value=".jsp" /> </beans:bean> <context:component-scan base-package="com.engilitycorp.leavetracker" /> <beans:bean id="leaveRequestForm" class="com.engilitycorp.leavetracker.model.LeaveRequest" /> </beans:beans> The constants: String LOGIN_FAILURE_PAGE = "loginFailure"; String LOGIN_PAGE = "login"; String CHOOSE_OPERATION_PAGE = "chooseOperation";

  How can we add a web page or a Windows Forms to the Outlook mail so that when I send a mail to a person he/she should be able to enter the data in the controls on the mail form? The user should also have the ability to save the data directly from the mail, instead of opening my web or a Windows application and update the data.

  Since I'm building a dynamic site, I need to track the changes between pages, ie. Ajax calls, POST, GET stuff and similar stuff.

• POST parameters strangely parsed inside phantomjs

  - by user61629

  I am working with PHP/CURL and would like to send POST data to my phantomjs script, by setting the postfields array below: In my php controller I have: $data=array('first' => 'John', 'last' => 'Smith'); $url='http://localhost:7788/'; $output = $this->my_model->get_data($url,$data); In my php model I have: public function get_data($url,$postFieldArray) { $ch = curl_init(); curl_setopt($ch, CURLOPT_COOKIEJAR, $cookieFile); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE); curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE); curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.0)"); curl_setopt($ch, CURLOPT_POST, TRUE); curl_setopt($ch, CURLOPT_POSTFIELDS, $postFieldArray); curl_setopt($ch, CURLOPT_URL, $url); $output = curl_exec($ch); In my phantomJS script that I am running locally I have: // import the webserver module, and create a server var server = require('webserver').create(); var port = require('system').env.PORT || 7788; console.log("Start Application"); console.log("Listen port " + port); // Create serever and listen port server.listen(port, function(request, response) { // Print some information Just for debbug console.log("We got some requset !!!"); console.log("request method: ", request.method); // request.method POST or GET if(request.method == 'POST' ){ console.log("POST params should be next: "); console.log("POST params: ",request.post); exit; } I first start and run the phantomjs script (myscript.js) from the command line, then I run my php script. The output is: $ phantomjs.exe myscript.js Start Application Listen port 7788 null We got some requset !!! request method: POST POST params should be next: POST params: ------------------------------e70d439800f9 Content-Disposition: form-data; name="first" John ------------------------------e70d439800f9 Content-Disposition: form-data; name="last" Smith ------------------------------e70d439800f9-- I'm confused about the the output. I was expecting something more like: first' => 'John', 'last' => 'Smith Can someone explain why it looks this way? How can I parse the request.post object to assign to variables inside myscript.js

  What do you think is the best way to implement an interactive grid similar to a Sudoku board for a native iPhone application? I did not see an object to fill this need in the SDK. Should I make a custom control for an individual cell, then initialize as many of them as I need in a grid form? Any and all comments are welcome. Thanks!

  Hey SO, I've got a pretty noob question for ya. I keep seeing this syntax: <%= Html.LabelFor(model => model.Email) %> ...and I have no idea what the = means. I thought it was syntax for linq2sql or ado.net entity framework but I'm just using straight ado.net. I don't understand why the VWD used that syntax when generating the Create form.

• 404 header - HTTP 1.0 or 1.1?

  - by keithjgrant

  So why does almost every example I can find (including this question form about a year ago) say that a 404 header should be HTTP/1.0 404 Not Found when we've really been using HTTP 1.1 for over a decade? Is there any reason not to send HTTP/1.1 404 Not Found instead? (Not that it matters all that much... I'm mostly just curious.)

• WPF windows locked when calling webservice. Even when run asynchronously

  - by SumGuy

  Hi there. I'm having a big problem when calling a web service from my WPF application. The application/window locks until the process has completed. I've attempted to run this asynchronously but the problem still persists. Currently, the web service call I'm making can last 45-60 seconds. It runs a process on the server to fetch a big chunk of data. As it take a little while I wanted to have a progress bar moving indeterminately for the user to see that the application hasn't stalled or anything (you know how impatatient they get). So: private void btnSelect_Click(object sender, RoutedEventArgs e) { wDrawingList = new WindowDrawingList(systemManager); AsyncMethodHandler caller = default(AsyncMethodHandler); caller = new AsyncMethodHandler(setupDrawingList); // open new thread with callback method caller.BeginInvoke((Guid)((Button)sender).Tag, MyAsyncCallback, null); } Click a button and the app will create the form that the async stuff will be posted to and set up the async stuff calling the async method. public bool setupDrawingList(Guid ID) { if (systemManager.set(ID)) { wDrawingList.Dispatcher.Invoke(DispatcherPriority.Background, new Action(() => { wDrawingList.ShowForm(); Hide(); })); return true; } return false; } This is the async method. The showForm method contains the calls to setup the new form including the monster web service call public void MyAsyncCallback(IAsyncResult ar) { // Because you passed your original delegate in the asyncState parameter of the Begin call, you can get it back here to complete the call. MethodDelegate dlgt = (MethodDelegate)ar.AsyncState; // Complete the call. bool output = dlgt.EndInvoke(ar); try { // Retrieve the delegate. AsyncResult result = (AsyncResult)ar; AsyncMethodHandler caller = (AsyncMethodHandler)result.AsyncDelegate; // Because this method is running from secondary thread it can never access ui objects because they are created // on the primary thread. // Call EndInvoke to retrieve the results. bool returnValue = caller.EndInvoke(ar); // Still on secondary thread, must update ui on primary thread UpdateUI(returnValue == true ? "Success" : "Failed"); } catch (Exception ex) { string exMessage = null; exMessage = "Error: " + ex.Message; UpdateUI(exMessage); } } public void UpdateUI(string outputValue) { // Get back to primary thread to update ui UpdateUIHandler uiHandler = new UpdateUIHandler(UpdateUIIndicators); string results = outputValue; // Run new thread off Dispatched (primary thread) this.Dispatcher.Invoke(System.Windows.Threading.DispatcherPriority.Normal, uiHandler, results); } public void UpdateUIIndicators(string outputValue) { // update user interface controls from primary UI thread sbi3.Content = "Processing Completed."; } Any help or theories are appreciated. I'm at a loss. Thanks in advance

• Invalid cast exception

  - by user127147

  I have a simple application to store address details and edit them. I have been away from VB for a few years now and need to refreash my knowledge while working to a tight deadline. I have a general Sub responsible for displaying a form where user can add contact details (by pressing button add) and edit them (by pressing button edit). This sub is stored in a class Contact. The way it is supposed to work is that there is a list with all the contacts and when new contact is added a new entry is displayed. If user wants to edit given entry he or she selects it and presses edit button Public Sub Display() Dim C As New Contact C.Cont = InputBox("Enter a title for this contact.") C.Fname = frmAddCont.txtFName.Text C.Surname = frmAddCont.txtSName.Text C.Address = frmAddCont.txtAddress.Text frmStart.lstContact.Items.Add(C.Cont.ToString) End Sub I call it from the form responsible for adding new contacts by Dim C As New Contact C.Display() and it works just fine. However when I try to do something similar using the edit button I get errors - "Unable to cast object of type 'System.String' to type 'AddressBook.Contact'." Dim C As Contact If lstContact.SelectedItem IsNot Nothing Then C = lstContact.SelectedItem() C.Display() End If I think it may be something simple however I wasn't able to fix it and given short time I have I decided to ask for help here. I have updated my class with advice from other members and here is the final version (there are some problems however). When I click on the edit button it displays only the input box for the title of the contact and actually adds another entry in the list with previous data for first name, second name etc. Public Class Contact Public Contact As String Public Fname As String Public Surname As String Public Address As String Private myCont As String Public Property Cont() Get Return myCont End Get Set(ByVal value) myCont = Value End Set End Property Public Overrides Function ToString() As String Return Me.Cont End Function Sub NewContact() FName = frmAddCont.txtFName.ToString frmStart.lstContact.Items.Add(FName) frmAddCont.Hide() End Sub Public Sub Display() Dim C As New Contact C.Cont = InputBox("Enter a title for this contact.") C.Fname = frmAddCont.txtFName.Text C.Surname = frmAddCont.txtSName.Text C.Address = frmAddCont.txtAddress.Text 'frmStart.lstContact.Items.Add(C.Cont.ToString) frmStart.lstContact.Items.Add(C) End Sub End Class

• Is there a declarative way to force a set of Buttons to be the same size?

  - by Jekke

  I'm writing a form in XAML that has multiple buttons with content of different sizes (ie "OK" and "Save As...") Ideally, I'd like them all to be the smallest size possible to hold the largest content. In the example above, both buttons would be the width necessary to hold "Save As..." plus the margins and padding. If they were Grid cells, I could use a SizeGroup. Is there a similar declaration for Buttons?
