  • Delphi 7 - Why does Windows 7 change encoding of characters in runtime?

    - by LukLed
    I have a delphi 7 form: and my code: when I run this form in Windows 7, I see: In design time, form had polish letters in first label, but it doesn't have them in runtime. It looks ok on Vista or Windows XP. When I set caption of second label in code, everything works fine and characters are properly encoded. First 5 codes of top label on Windows 7: 65 97 69 101 83 First 5 codes of top label on Windows Vista/XP: 165 185 202 234 140 First 5 codes of bottom label on every system: 165 185 202 234 140 Windows 7 changes encoding, why? My system settings seem to be ok. I have proper language set for non-unicode applications in control panel.

  • Read -> change -> save. Thread safe.

    - by Pavel Alexeev
    This code should automatically connect players when they enter a game. But the problem is when two users try to connect at the same time - in this case 2nd user can easily overwrite changes made by 1st user ('room_1' variable). How could I make it thread safe? def join(userId): users = memcache.get('room_1') users.append(userId) memcache.set('room_1', users) return users I'm using Google App Engine (python) and going to implement simple game-server for exchanging peers given by Adobe Stratus.

  • How can I change my code in Excel 2003 to allow me to paste to multiple cells?

    - by PikeCoAL
    Ran in to a little problem. If I try to paste to multiple cells that are in the range in the code below, I get a run time error 13, type mismatch. The cells in the range may have data other than X but I only want the hyperlink to appear if the cell contains X. It works fine if I just type an X in the cell or if I paste to one cell at a time. I will have times when I want to paste other text to mutiple cells in this range. Thanks to Remnant for his help on the original code. This one last hurdle will put me in the clear. Thx. Private Sub Worksheet_Change(ByVal Target As Range) Dim rangeLimit As Range Set rangeLimit = Range ("B9:B37,C9:C37,D9:D37,E9:E37,F9:F37,G9:G37,H9:H37,I9:I37,J9:J37,K9:K37,L9:L37,M9:M37") If Not Intersect(rangeLimit, Target) Is Nothing Then If Target = "x" Or Target = "X" Then Target.Hyperlinks.Add Anchor:=Target, Address:="", SubAddress:="Exceptions!A1", TextToDisplay:=Target.Value End If End If End Sub

  • Ushahidi - How to make the markers stay on the map on zoom change?

    - by Guttemberg
    I am using the platform Ushahidi Web-2.7.3 , see: http://ti5.net.br/provedorlegal.com.br, and when I zoom in beyond a certain level, the clustered markers disappear from the map. I also tested this on an older version of a site, see: http://movimentofichalimpa.org/mapa, where the clustered markers do not disappear on zooming in, but just become ungrouped, as is normal with a cluster strategy. How can I make the markers remain on the map when zooming in?

  • How do I temporarily change the require path in Ruby ($:)?

    - by John Feminella
    I'm doing some trickery with a bunch of Rake tasks for a complex project, gradually refactoring away some of the complexity in chunks at a time. This has exposed the bizarre web of dependencies left behind by the previous project maintainer. What I'd like to be able to do is to add a specific path in the project to require's list of paths to be searched, aka $:. However, I only want that path to be searched in the context of one particular method. Right now I'm doing something like this: def foo() # Look up old paths, add new special path. paths = $: $: << special_path # Do work ... bar() baz() quux() # Reset. $:.clear $: << paths end def bar() require '...' # If called from within foo(), will also search special_path. ... end This is clearly a monstrous hack. Is there a better way?

  • Form Field: How do I change the background on blur?

    - by Liso22
    I managed to remove the background when the user clicks on the field but I cannot restore it when it blurs! This is the field: <textarea class="question-box" style="width: 240px; background: white url('http://chusmix.com/Imagenes/contawidget.png') no-repeat 50% 50%; color: grey;" cols="12" rows="5" id="question-box-' . $questionformid . '" name="title" onblur="if(this.value == '') { this.style.color='#848484'; this.value=''this.style.background=' white url('http://chusmix.com/Imagenes/contawidget.png') no-repeat 50% 50%;e';}" onfocus="if (this.value == '') {this.style.color='#444'; this.style.background='none';}" type="text" maxlength="200" size="28"></textarea> Anyone knows what I'm doing wrong?? Thanks

  • Can i change the identity of the logged in user in ASP.net?

    - by Rising Star
    I have an ASP.net application I'm developing authentication for. I am using an existing cookie-based log on system to log users in to the system. The application runs as an anonymous account and then checks the cookie when the user wants to do something restricted. This is working fine. However, there is one caveat: I've been told that for each page that connects to our SQL server, I need to make it so that the user connects using an Active Directory account. because the system I'm using is cookie based, the user isn't logged in to Active Directory. Therefore, I use impersonation to connect to the server as a specific account. However, the powers that be here don't like impersonation; they say that it clutters up the code. I agree, but I've found no way around this. It seems that the only way that a user can be logged in to an ASP.net application is by either connecting with Internet Explorer from a machine where the user is logged in with their Active Directory account or by typing an Active Directory username and password. Neither of these two are workable in my application. I think it would be nice if I could make it so that when a user logs in and receives the cookie (which actually comes from a separate log on application, by the way), there could be some code run which tells the application to perform all network operations as the user's Active Directory account, just as if they had typed an Active Directory username and password. It seems like this ought to be possible somehow, but the solution evades me. How can I make this work?

  • XAML : How to change background color only in Design mode?

    - by Kave
    I have a control with white text foreground color and transparent background color. Later on this usercontrol will be added into a different control that carries the real background color. However during designing this, control due white foreground on white background in VS 2010, I can't obviously see anything. In there anyway to define a different color for just the design time? I have tried this: if (System.ComponentModel.DesignerProperties.IsInDesignTool) { LayoutRoot.Background = new SolidColorBrush(Colors.Blue); } But this doesn't work. Any tips? Thanks, Kave

  • How can I change standart input/output of another program?

    - by Azad Salahli
    I have a console application written in c++. It simply reads an integer from standard input(keyboard) and writes another integer to standard output(screen). Now I want to give some tests to that program and check its answers using another program. In another words, I want to write electron judge for that program. I want that program(which I want to test) to read from file and write to file without changing source code. How can I do that. I tried assigning input&output to files before executing c++ program, but it did not worked. assign(input,'temp.in'); reset(input); assign(output,'temp.out'); rewrite(output); exec('domino.exe'); close(input); close(output);

  • How to change the sorting of a view using hook_views_pre_view()?

    - by RD
    I've got the following: function view_sorter_views_pre_view(&$view) { // don't need $items if ($view->name == 'MOST_RECENT') { $insert = array(); $insert[order] = 'DESC'; //SORT ORDER $insert[id] = 'title'; $insert[table] = 'node'; $insert[field] = 'title'; $insert[override] = array(); $insert[override][button] = 'Override'; $insert[relationship] = 'none'; unset ($view->display['default']->display_options['sorts']['title']); $view->display['default']->display_options['sorts']['title'] = $insert; } } Basically, I'm just changing the sort order... but this does not appear on the view when opening it. Any idea why?

  • How to change CSS style of nested list items?

    - by Yasir
    I have a style for styling <a> elements in list items in a #navigation container. This is working fine. #navigation li a { text-decoration:none; background:#bfe5ff; color:#045e9f; width:125px; height:35px; padding-top:11px; display:block; float:left; margin-left:2px; text-align:center; font-size:18px; font-weight:bold; } Now in some <li>s I am inserting <div>s. In these I am again using a list again, but it should be different in style or have no style. When I put in <li>s, their style matches the outer <li> elements, but it should not. I am trying to use this: #newnavigation li a { font-size:12px; margin-left:20px; } but it's not working - it applies the "outer" styles. This is my markup: <ul id="navigation"> <li><a href="index.html">Home</a></li> <li><a href="about.html">About</a></li> <li><a href="contact.html">Contact</a></li> <li class="browse"> <a href="#">Browse</a> <div id="browsecontainer"> <h3>Browse By Category</h3> <li><a href="#"></a></li> </div> </li> </ul>

  • How do I change the style of an input box in IE7 on focus?

    - by Cen
    I know IE7 has issues... I've read posts here and on Google telling me I need to set the style by hand onfocus() and onblur(). However, everything I try isn't working! Here is my jQuery $(document).ready(function(){ if (jQuery.browser.msie === true) { $("input.date-picker").each(function(i) { var $foo= $(this); $foo.bind('onfocus onblur', function() { $(this).toggleClass('smalltxt-active'); }); }); }//end if }); The a corresponding box <input name="ctl00$SelectionContent$Selections1$txtDestinationDate" type="text" id="ctl00_SelectionContent_Selections1_txtDestinationDate" class="date-picker" style="width:80px;" /> I have already confirmed that my code is detecting MSIE. That I am getting a count of 2 input.date-picker objects. Any ideas? Thanks in advance,

  • Is there a better way to change user password in cakephp using Auth?

    - by sipiatti
    Hi, I am learning cakephp by myself. I tried to create a user controller with a changepassword function. It works, but I am not sure if this is the best way, and I could not googled up useful tutorials on this. Here is my code: class UsersController extends AppController { var $name = 'Users'; function login() { } function logout() { $this->redirect($this->Auth->logout()); } function changepassword() { $session=$this->Session->read(); $id=$session['Auth']['User']['id']; $user=$this->User->find('first',array('conditions' => array('id' => $id))); $this->set('user',$user); if (!empty($this->data)) { if ($this->Auth->password($this->data['User']['password'])==$user['User']['password']) { if ($this->data['User']['passwordn']==$this->data['User']['password2']) { // Passwords match, continue processing $data=$this->data; $this->data=$user; $this->data['User']['password']=$this->Auth->password($data['User']['passwordn']); $this->User->id=$id; $this->User->save($this->data); $this->Session->setFlash('Password changed.'); $this->redirect(array('controller'=>'Toners','action' => 'index')); } else { $this->Session->setFlash('New passwords differ.'); } } else { $this->Session->setFlash('Typed passwords did not match.'); } } } } password is the old password, passwordn is the new one, password2 is the new one retyped. Is there any other, more coomon way to do it in cake?

  • How can I change my JLabel to look like a table cell with Substance?

    - by DR
    I have a custom TableCellRenderer which returns a JLabel as the renderer component. Naturally the table cell now looks like a label and no longer like a table cell, which makes a difference especially when using Substance. Is it possible to modify the label so that the LaF renders it like an ordinary table cell? The best I could do was setting the background color of the label, but the borders and transition effets are missing.

  • Quantifying the amount of change in a git diff?

    - by Alex Feinman
    I use git for a slightly unusual purpose--it stores my text as I write fiction. (I know, I know...geeky.) I am trying to keep track of productivity, and want to measure the degree of difference between subsequent commits. The writer's proxy for "work" is "words written", at least during the creation stage. I can't use straight word count as it ignores editing and compression, both vital parts of writing. I think I want to track: (words added)+(words removed) which will double-count (words changed), but I'm okay with that. It'd be great to type some magic incantation and have git report this distance metric for any two revisions. However, git diffs are patches, which show entire lines even if you've only twiddled one character on the line; I don't want that, especially since my 'lines' are paragraphs. Ideally I'd even be able to specify what I mean by "word" (though \W+ would probably be acceptable). Is there a flag to git-diff to give diffs on a word-by-word basis? Alternately, is there a solution using standard command-line tools to compute the metric above?

  • How do I change the list using mutable lists in Racket or Scheme?

    - by exOne
    I need your help Can anyone help me? first question This procedure should modify each element which’s index in the list is even. The value of the element should be equal to the new-element. For example: (define number-list (1 56 8 1 43 9 78)) (modify-even-indices number-list 10) The new list: 1 10 8 10 43 10 78 second question This problem is the extended version of Question 1. (modify-even-odd-indices my-list new-element modification-type) This procedure should modify each element according to the modification-type. The modification-type can be even or odd. For example: (define number-list (1 56 8 1 43 9 78)) (modify-even-odd-indices number-list 10 ‘even’) The new list: 1 10 8 10 43 10 78 (modify-even-odd-indices number-list 10 ‘odd’) The new list: 10 56 10 1 10 9 10
