  • Git: changes not reflecting on other checkouts - huh?

    - by Chad Johnson
    Okay, so, I have my branches (git branch -a): * chat master remotes/origin/HEAD -> origin/master remotes/origin/chat I make changes (still with the 'chat' branch checkout out), commit, and push. I go to my server, on which I have a clone of the repository, and I do a fetch: git getch then I switch to the chat branch: git checkout --track -b chat origin/chat and I event do a pull, just to make sure everything is up to date: git pull and my changes from my other computer are NOT. THERE. What the heck am I doing wrong? If I had hair, I would have pulled it out. Thankfully I am bald. When I try a 'git commit' again, I get this # On branch chat # Changed but not updated: # (use "git add/rm <file>..." to update what will be committed) # (use "git checkout -- <file>..." to discard changes in working directory) # # modified: app/controllers/chat_controller.rb # modified: app/views/dashboard/index.html.erb # modified: app/views/dashboard/layout.js.erb # modified: app/views/layouts/dashboard.html.erb # deleted: app/views/project/.tmp_edit.html.erb.55742~ # deleted: app/views/project/.tmp_edit.html.erb.83482~ # modified: public/stylesheets/dashboard/layout.css # # Untracked files: # (use "git add <file>..." to include in what will be committed) # # .loadpath # .project # config/database.yml # config/environments/development.yml # config/environments/production.yml # config/environments/test.yml # log/ no changes added to commit (use "git add" and/or "git commit -a")

  • Fix a 404: missing parameters error from a GET request to CherryPy

    - by norabora
    I'm making a webpage using CherryPy for the server-side, HTML, CSS and jQuery on the client-side. I'm also using a mySQL database. I have a working form for users to sign up to the site - create a username and password. I use jQuery to send an AJAX POST request to the CherryPy which queries the database to see if that username exists. If the username exists, alert the user, if it doesn't, add it to the database and alert success. $.post('submit', postdata, function(data) { alert(data); }); Successful jQuery POST. I want to change the form so that instead of checking that the username exists on submit, a GET request is made as on the blur event from the username input. The function gets called, and it goes to the CherryPy, but then I get an error that says: HTTPError: (404, 'Missing parameters: username'). $.get('checkUsername', getdata, function(data) { alert(data); }); Unsuccessful jQuery GET. The CherryPy: @cherrypy.expose def submit(self, **params): cherrypy.response.headers['Content-Type'] = 'application/json' e = sqlalchemy.create_engine('mysql://mysql:pw@localhost/6470') c = e.connect() com1 = "SELECT * FROM `users` WHERE `username` = '" + params["username"] + "'" b = c.execute(com1).fetchall() if not len(b) > 0: com2 = "INSERT INTO `6470`.`users` (`username` ,`password` ,`website` ,`key`) VALUES ('" com2 += params["username"] + "', MD5( '" + params["password"] + "'), '', NULL);" a = c.execute(com2) c.close() return simplejson.dumps("Success!") #login user and send them to home page c.close() return simplejson.dumps("This username is not available.") @cherrypy.expose def checkUsername(self, username): cherrypy.response.headers['Content-Type'] = 'application/json' e = sqlalchemy.create_engine('mysql://mysql:pw@localhost/6470') c = e.connect() command = "SELECT * FROM `users` WHERE `username` = '" + username + "'" a = c.execute(command).fetchall(); c.close() sys.stdout.write(str(a)) return simplejson.dumps("") I can't see any differences between the two so I don't know why the GET request is giving me a problem. Any insight into what I might be doing wrong would be helpful. If you have ideas about the jQuery, CherryPy, config files, anything, I'd really appreciate it.

  • Intermittent bug - IE6 showing file as text in browser, rather than as file download

    - by Richard Ev
    In an ASP.NET WebForms 2.0 site we are encountering an intermittent bug in IE6 whereby a file download attempt results in the contents of the being shown directly in the browser as text, rather than the file save dialog being displayed. Our application allows the user to download both PDF and CSV files. The code we're using is: HttpResponse response = HttpContext.Current.Response; response.Clear(); response.AddHeader("Content-Disposition", "attachment;filename=\"theFilename.pdf\""); response.ContentType = "application/pdf"; response.BinaryWrite(MethodThatReturnsFileContents()); response.End(); This is called from the code-behind click event handler of a button server control. Where are we going wrong with this approach? Edit Following James' answer to this posting, the code I'm using now looks like this: HttpResponse response = HttpContext.Current.Response; response.ClearHeaders(); // Setting cache to NoCache was recommended, but doing so results in a security // warning in IE6 //response.Cache.SetCacheability(HttpCacheability.NoCache); response.AppendHeader("Content-Disposition", "attachment; filename=\"theFilename.pdf\""); response.ContentType = "application/pdf"; response.BinaryWrite(MethodThatReturnsFileContents()); response.Flush(); response.End(); However, I don't believe that any of the changes made will fix the issue.

  • Advice on a simple Windows Form

    - by Austin Hyde
    I have a VERY simple windows form that the user uses to manage "Stores". Each store has a name and number, and is kept in a corresponding DB table. The form has a listbox of stores, an add button that creates a new store, a delete button, and an edit button. Beside those I have text boxes for the name and number, and save/cancel buttons. When the user chooses a store from the list box, and clicks 'edit', the textboxes become populated and save/cancel become active. When the user clicks 'add', I create a new Store, add it to the listbox, activate the textboxes and save/cancel buttons, then commit it to the database when the user clicks 'save', or discards it when the user clicks 'cancel'. Right now, my event system looks like this (in psuedo-code. It's just shorter that way.) add->click: store = new Store() listbox.add(store) populateAndEdit(store) delete->click: store = listbox.selectedItem db.deleteOnSubmit(store) listbox.remove(store) db.submit() edit->click: populateAndEdit(listbox.selectedItem) save->click: parseAndSave(listbox.selectedItem) db.submit() disableTexts() cancel->click: disableTexts() The problem is in how I determine if we are inserting a new Store, or updating an existing one. The obvious solution to me would be to make it a "modal" process - that is, when I click edit, I go into edit mode, and the save button does things differently than if I were in add mode. I know I could make this more MVC-like, but I don't really think this simple form merits the added complexity. I'm not very experienced with winforms, so I'm not sure if I even have the right idea for how to tackle this. Is there a better way to do this? I would like to keep it simple, but usable.

  • override OnPaint for a Windows.Forms.Control Flickering?

    - by Danpe
    I create a new Control and overided the OnPaint event: protected override void OnPaint(PaintEventArgs e) { Graphics g = e.Graphics; _ammo = PitControl.Ammo; var AmmoSize = g.MeasureString(_ammo.ToString(), Properties.Settings.Default.AmmoFont).ToSize(); g.DrawString(_ammo.ToString(), Properties.Settings.Default.AmmoFont, Brushes.WhiteSmoke, Ammo.Location.X - 1, Ammo.Location.Y + Ammo.Height / 2 - AmmoSize.Height / 2 + 1); Rectangle DrawAmmo = new Rectangle(this.Width - Ammo.Height - _margin, Ammo.Location.Y, Ammo.Height, Ammo.Height); for (int i = _ammo; i > 0; i--) if (i % 2 == 0) g.DrawLine(_ammoPen, Ammo.Location.X + Ammo.Width - i - 1, Ammo.Location.Y + 3, Ammo.Location.X + Ammo.Width - i - 1, Ammo.Location.Y + Ammo.Height - 3); g.DrawRectangle(Pens.Orange, Ammo); g.DrawImage(Properties.Resources.ammunition, DrawAmmo.Location.X, DrawAmmo.Location.Y, DrawAmmo.Height, DrawAmmo.Height); } The problem is when i'm changing the Ammo then all the control flicks. It doesn't look good. Anyway to make the lines that i draw on this line: g.DrawLine(_ammoPen, Ammo.Location.X + Ammo.Width - i - 1, Ammo.Location.Y + 3, Ammo.Location.X + Ammo.Width - i - 1, Ammo.Location.Y + Ammo.Height - 3); Just disapeare when ammo is changing ?

  • jQuery removing elements from DOM put still reporting as present

    - by RyanP13
    Hi, I have an address finder system whereby a user enters a postcode, if postcode is validated then an address list is returned and displayed, they then select an address line, the list dissappears and then the address line is split further into some form inputs. The issue i am facing is when they have been through the above process then cleared the postcode form field, hit the find address button and the address list re-appears. Event though the list and parent tr have been removed from the DOM it is still reporting it is present as length 1? My code is as follows: jQuery // when postcode validated display box var $addressList = $("div#selectAddress > ul").length; // if address list present show the address list if ($addressList != 0) { $("div#selectAddress").closest("tr").removeClass("hide"); } // address list hidden by default // if coming back to modify details then display address inputs var $customerAddress = $("form#detailsForm input[name*='customerAddress']"); var $addressInputs = $.cookies.get('cpqbAddressInputs'); if ($addressInputs) { if ($addressInputs == 'visible') { $($customerAddress).closest("tr").removeClass("hide"); } } else { $($customerAddress).closest("tr").addClass("hide"); } // Need to change form action URL to call post code web service $("input.findAddress").live('click', function(){ var $postCode = encodeURI($("input#customerPostcode").val()); if ($postCode != "") { var $formAction = "customerAction.do?searchAddress=searchAddress&custpc=" + $postCode; $("form#detailsForm").attr("action", $formAction); } else { alert($addressList);} }); // darker highlight when li is clicked // split address string into corresponding inputs $("div#selectAddress ul li").live('click', function(){ $(this).removeClass("addressHover"); //$("li.addressClick").removeClass("addressClick"); $(this).addClass("addressClick"); var $splitAddress = $(this).text().split(","); $($customerAddress).each(function(){ var $inputCount = $(this).index("form#detailsForm input[name*='customerAddress']"); $(this).val($splitAddress[$inputCount]); }); $($customerAddress).closest("tr").removeClass("hide"); $.cookies.set('cpqbAddressInputs', 'visible'); $(this).closest("tr").fadeOut(250, function() { $(this).remove(); }); });

  • Low-level Keyboard Hooks/SendInput with Winkey+L possible? (workstation lockout is intercepted in Vi

    - by Brian Jorgensen
    I work on a project called UAWKS (Unofficial Apple Wireless Keyboard Support) that helps Windows users use Apple's bluetooth keyboard. One of the main goals of UAWKS is to swap the Cmd key (which behaves as Winkey in Windows) with Ctrl, allowing users to do Cmd+C for copy, Cmd+T for new tab, etc. It is currently developed using AutoHotkey, which worked pretty well under Windows XP. However, on Vista and Windows 7, Cmd+L causes problems: Regardless of low-level keyboard hooks, Winkey+L is always intercepted by Windows and normally locks the workstation... You can disable workstation locking with this registry hack, but pressing Winkey+L still can't be rebound in AHK Pressing Winkey+L leaves Winkey in the Keydown state until the next (additional) Winkey Up. Simulating a Keyup event doesn't seem to work either! It seems that Winkey+L is a special chord that messes everything else up. I've looked through the AHK source code, and they try to address this problem in SendKey() in keyboard_mouse.cpp (near line 883 in v1.0.48.05), but it doesn't work. I wrote up my own low-level keyboard hook application in C#, and I see the same problem. Has anyone else run into this? Is there a workaround?

  • Hyperlink in Silverlight AccordionItem HeaderTemplate

    - by Charlie Brown
    I have created a HeaderTemplate for my accordions where I want to display a text block on one side of the header and a hyperlink on the right side. The display is working correctly, but the click event is not called when the user clicks, I'm guessing b/c the header itself is trapping the click for expand/contract. <layoutToolkit:Accordion> <layoutToolkit:AccordionItem IsSelected="True"> <layoutToolkit:AccordionItem.HeaderTemplate> <DataTemplate> <StackPanel Orientation="Horizontal" Height="20"> <TextBlock Margin="0,0,700,0">Cancel Postcards</TextBlock> <HyperlinkButton Content="Next Call" Foreground="Blue" Click="NextCancel_Click" /> </StackPanel> </DataTemplate> </layoutToolkit:AccordionItem.HeaderTemplate> ..... more code .... Is there a way to get the hyperlink to respond to events without practically creating a new control?

  • How to maintain a persistant network-connection between two applications over a network?

    - by John
    I was recently approached by my management with an interesting problem - where I am pretty sure I am telling my bosses the correct information but I really want to make sure I am telling them the correct stuff. I am being asked to develop some software that has this function: An application at one location is constantly processing real-time data every second and only generates data if the underlying data has changed in any way. On the event that the data has changed send the results to another box over a network Maintains a persistent connection between the both machines, altering the remote box if for some reason the network connection went down From what I understand, I imagine that I need to do some reading on doing some sort of TCP/IP socket-level stuff. That way if the connection is dropped the remote location will be aware that the data it has received may be stale. However management seems to be very convinced that this can be accomplished using SOAP. I was under the impression that SOAP is more or less a way for a client to initiate a procedure from a server and get some results via the HTTP protocol. Am I wrong in assuming this? I haven't been able to find much information on how SOAP might be able to solve a problem like this. I feel like a lot of people around my office are using SOAP as a buzzword and that has generated a bit of confusion over what SOAP actually is - and is capable of. Any thoughts on how to accomplish this task would be appreciated!

  • question about jQuery droppable/draggable.

    - by FALCONSEYE
    I modified a sample photo manager application. photo manager application Instead of photos, I have employee records coming from a query. My version will let managers mark employees as on vacation, or at work. One of the things I did is to include employee ids like <a href="123">. I get the ids from event.target. This works for the click function but not for the "droppable" function. This is what I have for the click function: $('ul.gallery > li').click(function(ev) { var $item = $(this); var $unid = ev.target; var $target = $(ev.target); if ($target.is('a.ui-icon-suitcase')) { deleteImage($item,$unid); } else if ($target.is('a.ui-icon-arrowreturnthick-1-w')) { recycleImage($item,$unid); } return false; }); ev.target correctly gives the employee id. when i try the same in one of the droppable functions: $gallery.droppable({ accept: '#suitcase li', activeClass: 'custom-state-active', drop: function(ev, ui) { var $unid = ev.target; alert($unid); recycleImage(ui.draggable,$unid); } }); the alert(ui) gives me [object]. What's in this object? How do i get the href out of this? thanks

  • How can I get a custom made set of checkboxes return values in the postback?

    - by AngryHacker
    I have the following in an aspx page: <td colspan="2"> <% DisplayParties(); %> </td> In the code behind for the aspx page, i have this (e.g. I build HTML for the checkboxes): public void DisplayParties() { var s = new StringBuilder(); s.Append("<input type=\"checkbox\" id=\"attorney\" value=\"12345\"/>"); s.Append("<input type=\"checkbox\" id=\"attorney\" value=\"67890\"/>"); s.Append("<input type=\"checkbox\" id=\"adjuster\" value=\"125\"/>"); Response.WriteLine(s.ToString()); } Not my proudest moment, but whatever. The problem is that when this page posts back via some event on the page, I never get these tags in the Request.Form collection. Is this simply how ASP.NET works (e.g. only server-side control post back) or am I missing something simple. My understanding was that a postback should bring back all the form variables.

  • iTextSharp Overlay Image

    - by pennylane
    Hi guys I have an instance where I have a logo image as part of some artwork.. If a user uploads a new logo I have a form field which is larger than the default logo. I then use that form field to position the new image. The problem is I need to set the background colour of that form field to white so that it covers the old logo in the event that the new image is smaller than the old logo.. what I have done is: foreach (var imageField in imageReplacements) { fields.SetFieldProperty(imageField.Key, "bgcolor", iTextSharp.text.Color.WHITE, null); fields.RegenerateField(imageField.Key); PdfContentByte overContent = stamper.GetOverContent(imageField.Value.PageNumber); float[] logoArea = fields.GetFieldPositions(imageField.Key); if (logoArea != null) { iTextSharp.text.Rectangle logoRect = new iTextSharp.text.Rectangle(logoArea[1], logoArea[2], logoArea[3], logoArea[4]); var logo = iTextSharp.text.Image.GetInstance(imageField.Value.Location); if (logo.Width >= logoRect.Width || logo.Height >= logoRect.Height) { logo.ScaleToFit(logoRect.Width, logoRect.Height); } logo.Alignment = iTextSharp.text.Image.ALIGN_LEFT; logo.SetAbsolutePosition(logoRect.Left, logoArea[2] + (logoRect.Height - logo.ScaledHeight) / 2); // left: logoArea[3] - logo.ScaledWidth + (logoRect.Width - logo.ScaledWidth) / 2 overContent.AddImage(logo); } } The problem with this is that the background colour of the field is set to white and the image then doesn't appear.. i remove the SetFieldProperty and RegenerateField commands and the image replacement works fine.. is there a way to set a stacking order on layers?

  • Bing Map on Windows Phone - add click events to pushpins; display more details

    - by Will Gill
    I have a WP Phone app using a Bing Map control. I have an array of objects, and each object has a location. I iterate the array to place the pins on the map (see below). I have a touch event bound to each pin to allow the user to tap the pin to start an action. Now - I would like, on tap, to show information from the object that relates to that pin to be shown in a textbox. How can I retrieve the object from the array that corresponds to the pushpin that was tapped/clicked? foreach (wikiResult result in arrayResults) { double lat = double.Parse(result.Latitude, CultureInfo.InvariantCulture); double lng = double.Parse(result.Longitude, CultureInfo.InvariantCulture); statusTextBlock.Text = result.Latitude + " " + result.Longitude + " " + lat + " " + lng; GeoCoordinate d = new GeoCoordinate(lat, lng); Pushpin pin; pin = new Pushpin(); pin.Location = d; pin.Content = result.Name; pin.MouseLeftButtonUp += new MouseButtonEventHandler(pin1_MouseLeftButtonUp); myMap.Children.Add(pin); } void pin1_MouseLeftButtonUp(object sender, MouseButtonEventArgs e) { //display the content from the object in a text box } Many thanks in advance!

  • Visual Studio 2008 Installer, Custom Action. Breakpoint not firing.

    - by Snake
    Hi, I've got an installer with a custom action project. I want the action to fire at install. The action fires, when I write something to the event log, it works perfectly. But I really need to debug the file since the action is quite complicated. So I've got the following installer class: namespace InstallerActions { using System; using System.Collections; using System.Collections.Generic; using System.ComponentModel; using System.Configuration.Install; using System.Diagnostics; using System.IO; [RunInstaller(true)] // ReSharper disable UnusedMember.Global public partial class DatabaseInstallerAction : Installer // ReSharper restore UnusedMember.Global { public DatabaseInstallerAction() { InitializeComponent(); } public override void Install(IDictionary stateSaver) { base.Install(stateSaver); System.Diagnostics.Debugger.Launch(); System.Diagnostics.Debugger.Break(); // none of these work Foo(); } private static void Foo() { } } } The installer just finalizes without warning me, it doesn't break, it doesn't ask me to attach a debugger. I've tried debug and release mode. Am I missing something? Thanks -Snake

  • about option buttons in User form

    - by Mars
    I have a question: I need to create a user form that contain that usual OK and Cancel Buttons. It also should contain two sets of Options buttons, each set placed inside a frame. The captions on the first set should be basketball, baseball, football, the captions on the second set should be watch on TV and Go to games. I need to write the event handlers and code in a module so that when the program runs, the user sees the form. If the user makes a couple of choices and clicks OK, he should see a message like "Your favorite sport is basketball, and you usually watch on TV." If the user clicks Cancel, the message "Sorry you don't want to play" should appear. I think I almost have it working, but I don't know why I cannot successfully execute the Macro. My Code is : Option Explicit Private Sub CommandButton2_Click() MsgBox ("sorry if you don't want to play") End Sub Private Sub commandbuttons_Click() Dim optbasket As String, optbaseball As String, optfootball As String Dim optwog As String, optgtg As String Select Case True Case optbasket optbasket = True Case optbaseball optbaseball = True Case optfootball optfootball = True End Select If optwog Then optwog = True Else optgtg = True End If btnok = MsgBox("you favorite sport is " & Frame1.Value & "you usually " & Frame2.Value & ",") End Sub Private Sub OptionButton1_Click() End Sub Private Sub btmcancel_Click() End Sub Private Sub btnok_Click() End Sub Private Sub Frame1_Click() End Sub Private Sub Frame2_Click() End Sub Private Sub optbaseball_Click() End Sub Private Sub optbasketball_Click() End Sub Private Sub optfootball_Click() End Sub Thank you very much!!!

  • Can I prevent a Linux user space pthread yielding in critical code?

    - by KermitG
    I am working on an user space app for an embedded Linux project using the 2.6.24.3 kernel. My app passes data between two file nodes by creating 2 pthreads that each sleep until a asynchronous IO operation completes at which point it wakes and runs a completion handler. The completion handlers need to keep track of how many transfers are pending and maintain a handful of linked lists that one thread will add to and the other will remove. // sleep here until events arrive or time out expires for(;;) { no_of_events = io_getevents(ctx, 1, num_events, events, &timeout); // Process each aio event that has completed or thrown an error for (i=0; i<no_of_events; i++) { // Get pointer to completion handler io_complete = (io_callback_t) events[i].data; // Get pointer to data object iocb = (struct iocb *) events[i].obj; // Call completion handler and pass it the data object io_complete(ctx, iocb, events[i].res, events[i].res2); } } My question is this... Is there a simple way I can prevent the currently active thread from yielding whilst it runs the completion handler rather than going down the mutex/spin lock route? Or failing that can Linux be configured to prevent yielding a pthread when a mutex/spin lock is held?

  • WPF Usercontrol with textboxes

    - by benPearce
    I have a WPF user control with a number of textboxes, this is hosted on a WPF window. The textboxes are not currently bound but I cannot type into any of them. I have put a breakpoint in the KeyDown event of one of the textboxes and it hits it fine and I can see the key I pressed. The textboxes are declared as <TextBox Grid.Row="3" Grid.Column="4" x:Name="PostcodeSearch" Style="{StaticResource SearchTextBox}" KeyDown="PostcodeSearch_KeyDown"/> The style is implemented as <Style x:Key="SearchTextBox" TargetType="{x:Type TextBox}"> <Setter Property="Control.Margin" Value="2"/> <Setter Property="Height" Value="20"/> <Setter Property="Width" Value="140"/> <Setter Property="HorizontalAlignment" Value="Left"/> </Style> I am hoping I have overlooked something obvious. EDIT: I only added the KeyDown and KeyUp events just to prove that the keys presses were getting through. I do not have any custom functionality.

  • Dynamically Run IQueryable Method

    - by Micah
    Hi! I'm trying to run the Count() function of a Linq statement in an overriden Gridview function. Basically, I want to be able to assign a linq query to a gridview, and on the OnDataBound(e) event in my new extended gridview have it retrieve the count, using the IQueryable. This is where I'm at so far: protected override void OnDataBound(EventArgs e) { IEnumerable _data = null; if (this.DataSource is IQueryable) { _data = (IQueryable)this.DataSource; } System.Type dataSourceType = _data.GetType(); System.Type dataItemType = typeof(object); if (dataSourceType.HasElementType) { dataItemType = dataSourceType.GetElementType(); } else if (dataSourceType.IsGenericType) { dataItemType = dataSourceType.GetGenericArguments()[0]; } else if (_data is IEnumerable) { IEnumerator dataEnumerator = _data.GetEnumerator(); if (dataEnumerator.MoveNext() && dataEnumerator.Current != null) { dataItemType = dataEnumerator.Current.GetType(); } } Object o = Activator.CreateInstance(dataItemType); object[] objArray = new object[] { o }; RowCount = (int)dataSourceType.GetMethod("Count").Invoke(_data, objArray); Any ideas? I'm really new with working with IQueryables and Linq so I may be way off. How can I get my _data to allow me to run the Count function?

  • SQL Server log backups "stalling"

    - by MattK
    I have interited a box running SQL Server 2008 and Windows 2003, and have had a few events where largeish (35GB) log backups "stall", both before and after the installation of SQL 2008 SP1. The server log ships to a standby, so regular log backups are taken at 15 minute intervals. However, after an index reorg causes the log to grow to about 35GB (on a DB with about 17GB of data), the next log backup runs to ~95% completion, then seems to stop. The process shows as suspended, with a wait state of BACKUPIO. CPU, read, and write activity on the SPID also does not change, and the process stays in this state for hours, when normally a backup of this size should complete in about 20 minutes. This server has a single RAID-1 volume, thus the source database files and destination backup files are on the same volume. However, I cannot determine if another process is blocking the backup. The backup SPID cannot be killed, and the only way to terminate the log backup and clear the lock on the backup file is to cycle the SQL Server service. There was one event where the backup terminated completely, with an error that another process had locked the backup file, but no details about what that process was. Can anyone suggest a cause or diagnostic process to this situation?
