  • Adding Values to a Byte Array

    - by rross
    I'm starting with the two values below: finalString = "38,05,e1,5f,aa,5f,aa,d0"; string[] holder = finalString.Split(','); I'm looping thru holder like so: foreach (string item in holder) { //concatenate 0x and add the value to a byte array } On each iteration I would like to concatenate a 0x to make it a hex value and add it to a byte array. This is what I want the byte array to be like when I finish the loop: byte[] c = new byte[]{0x38,0x05,0xe1,0x5f,0xaa,0x5f,0xaa,0xd0}; So far all my attempts have not been successful. Can someone point me in the right direction?

  • Adding custom fields to users in django

    - by Gaurav
    I am the create_user() function that Django provides to create my users. Also I want to store additional information about the users. So I tried following the instructions given at http://docs.djangoproject.com/en/dev/topics/auth/#storing-additional-information-about-users but I cannot get it to work for me. Is there a step-by-step guide that I can follow to get this to work for me? Also, once I have added these custom fields, I would obviously need to add / edit / delete data from them. I cannot seem to find any instructions on how to do this.

  • Adding a javascript immediate after body tag

    - by prabdrup
    I am making a drupal module. My requirement in the module is that when the module is activated then it needs to add a javascript in page.tpl file just after the body tag. Can anyone help me how to do this. I have tried using drupal_add_js but it will not exactly put the script after body tag, rather puts inside the head or below in footer. I also tried using template variable and preprocess method but the problem is the preprocess method replaces the old value of that variable with the new one. Is there a way how i can implement this in.

  • Specifying a unique control name when adding at runtime (like the VS IDE)

    - by user316383
    hi, I have a basic IDE for a user control i am building. It allows me to add labels to a panel and move them around, like a very basic form designer. When I add the controls to the panel at runtime, I'd like to give the control a unique name string like how the VS IDE tracks the controls it already has and adds an extra number when it creates the default control name. I have tried checking the controls collection each time a new control is added, but wasnt sure if there was a good string comparison method to return a name with a unique number on the end that hasn't been used yet.

  • NHibernate SchemaUpdate adding existing foreign keys again?

    - by afsharm
    I'm using SchemaUpdate to synchronize my hbms with existing database. Database has recently created based on hbms and is completely up-to-date. But SchemaUpdate generates all foreign key constraints again. For example suppose you have Student and Teacher. Student has association to Teacher with name ArtTeacher. ArtTeacher is a foreign key from Student to Teacher. Suppose database is up-to-date and currently holde Student, Teacher and their foreign key relation. So HBM and Database are equivalent. Know SchemaUpdate must not do anything but when I see its generated scripts, it re-produce that foreign key again. Why this happens? Is there any way to avoid it?

  • Automatic form generation software

    - by Jonathan
    Hi! I'm using winforms. I spend a lot of time drawing forms (maybe not a lot, but it is a boring task). To sum up... I want to develop a simple aplication that connect to a sql server database, let the user to select a table, and put the controls in a form for me (generate the designer code), based on the tipe of each column. Then my app will name each control like the column of the table, set the maxlengh property (if the type is varchar), and create a label with the same text near the control. If the column is a FK, then the app will draw a combobox and so on. I saw that Telerik Open ORM make something like this, but I only need a simple app for the IU Generation. If the same day I finish my little application I discover a tool that make the same... I will feel myself stupid :D Are there any tool out there that do this work for me? Thanks

  • Adding and sorting a linked list in C

    - by user1202963
    In my assignment, I have to write a function that takes as arguments a pointer to a "LNode" structure and an integer argument. Then, I have to not only add that integer into the linked list, but also put place it so that the list is in proper ascending order. I've tried several various attempts at this, and this is my code as of posting. LNode* AddItem(LNode *headPtr, int newItem) { auto LNode *ptr = headPtr; ptr = malloc(sizeof(LNode)); if (headPtr == NULL) { ptr->value = newItem; ptr->next = headPtr; return ptr; } else { while (headPtr->value > newItem || ptr->next != NULL) { printf("While\n"); // This is simply to let me know how many times the loop runs headPtr = headPtr->next; } ptr->value = newItem; ptr->next = headPtr; return ptr; } } // end of "AddItem" When I run it, and try to insert say a 5 and then a 3, the 5 gets inserted, but then the while loop runs once and I get a segmentation fault. Also I cannot change the arguments as it's part of a skeletal code for this project. Thanks to anyone who can help. If it helps this is what the structure looks like typedef struct LNode { int value; struct LNode *next; } LNode;

  • Adding International support in Erlang Web 1.4

    - by Roberto Aloi
    I'm trying to add international support for a website based on the Erlang Web 1.4. I would like to have a couple of links on every page (the notorious Country flags) that allow the user to set his language session variable. What I have right now is a link like: <li><a href="/session/language/en">English</a></li> Where, in the session controller I do: language(Args) -> LanguageId = proplists:get_value(id, Args), case language_is_supported(LanguageId) of false -> ok; true -> wpart:fset("session:lang", LanguageId) end, {redirect, "/"}. The problem is that, after setting the preferred language, I would like the user to be redirected to the page he was visiting before changing the language. In this case the "__path" variable doesn't help because it contains the language request and not the "previous" one. How could I resolve this situation? I'm probably using the wrong approach but I cannot thing to anything else right now.

  • Help adding a backgroundView to UITableViewCell

    - by Alex
    I'm getting really desperate trying to add a UIImageView to UITableViewCell.backgroundView. All my efforts have resulted in this crappy rendering: It looks like the cell's label's white background is sitting on top of cell's background and covering portions of it. I tried setting the label's background color to clear, or some other color and it does not have any event. It is always white. The reason I know it's the text label's background causing this white area is that if I don't do [cell setText:@"Cell text here"]; the white area is gone and I see just the cell's background image. Here's the code that I'm using. The table view is added in the .xib file and UITableView is added to UIViewController: - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { return 1; } - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return [myCollection.items count]; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { NSUInteger rowIndex = indexPath.row; static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; cell.backgroundView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"darkCellBackground.png"]]; cell.selectedBackgroundView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"darkCellBackground.png"]]; } [cell setText:@"Cell text here"]; return cell; } - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { // Navigation logic may go here. Create and push another view controller. // AnotherViewController *anotherViewController = [[AnotherViewController alloc] initWithNibName:@"AnotherView" bundle:nil]; // [self.navigationController pushViewController:anotherViewController]; // [anotherViewController release]; [tableView deselectRowAtIndexPath:indexPath animated:YES]; } - (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath { return NO; } I'm sure I'm doing something wrong but cant quite figure out what.

  • Need Help: adding MouseListeners to JComponents (Drawing a JComponent and then attaching a MouseListener)

    - by user1074574
    Drawing a JComponent and then attaching a MouseListener seems very simple to me, but not in this case: I'm having a problem with a MouseListener attached to a child JComponent; here's some brief code to help describe it: Note: The BGT class has implemented ActionListers/MouseListeners that do not have any code in them, and 'figures' is an array of SwingThings. public class GC extends BGT{ public GC(){ super(); buildJMenu(); drawPanel.addMouseListener(this); //drawPanel being the panel that draws the JComponents (it is a public variable in the BGT class) drawPanel.addMouseMotionListener(this); this.addMouseListener(this); } public static void main(String[] args){ GC a = new GC(); }... public void mouseClicked(MouseEvent e) { System.out.println(e.getSource()); //This only seems to print out the DrawPanel's information }... public void mouseReleased(MouseEvent e) { repaint(); ... tempMyJTextField = new MyJTextField(startX, startY, width, height); tempMyJTextField.addMouseListener(this); tempMyJTextField.addMouseMotionListener(this); figures.add(tempMyJTextField); for(int i = 0; i < figures.size(); i++) figures.get(i).addTo(drawPanel); } This is the addTo method in the MyJTextField class: public class MyJTextField extends JTextField implements SwingThing{ ... public void addTo(JPanel p) { p.add(myTextField); } ... } In the MouseClicked event it never registers that the JComponent was clicked. (The drawing/painting works fine) Thanks.

  • Adding fields to Django form dynamically (and cleanly)

    - by scott
    Hey guys, I know this question has been brought up numerous times, but I'm not quite getting the full implementation. As you can see below, I've got a form that I can dynamically tell how many rows to create. How can I create an "Add Row" link that tells the view how many rows to create? I would really like to do it without augmenting the url... # views.py def myView(request): if request.method == "POST": form = MyForm(request.POST, num_rows=1) if form.is_valid(): return render_to_response('myform_result.html', context_instance=RequestContext(request)) else: form = MyForm(num_rows=1) return render_to_response('myform.html', {'form':form}, context_instance=RequestContext(request)) # forms.py class MyForm(forms.Form): def __init__(self, *args, **kwargs): num_rows = kwargs.pop('num_rows',1) super(MyForm, self).__init__(*args, **kwargs) for row in range(0, num_rows): field = forms.CharField(label="Row") self.fields[str(row)] = field # myform.html http://example.com/myform <form action="." method="POST" accept-charset="utf-8"> <ul> {% for field in form %} <li style="margin-top:.25em"> <span class="normal">{{ field.label }}</span> {{ field }} <span class="formError">{{ field.errors }}</span> </li> {% endfor %} </ul> <input type="submit" value="Save"> </form> <a href="ADD_ANOTHER_ROW?">+ Add Row</a>

  • Adding Another Parameter to my Custom jQuery Gallery

    - by steve
    My website currently uses a custom jQuery gallery system that I've developed... it works well, but I want to add one capability that I can't seem to figure out. I want the user to, instead of having to click each thumbnail, also be able to click the full image itself to advance in the gallery. Working gallery is here: http://www.studioimbrue.com The code is as follows: $('.thumbscontainer ul li a').click(function() { var li_index = $(this).parents('ul').children('li').index($(this).parent("li"));    $(this).parents('.thumbscontainer').parent().find('.captions ul li').fadeOut(); $(this).parents('.thumbscontainer').parent().find('.captions ul li:eq('+li_index+')').fadeIn(); }); }); and the gallery HTML markup is as follows: <div class="container"> <div class="captions" id="usbdrive"> <ul> <li style="display:block"> <img src="images/portfolio/usbdrive/1.jpg" /> <div class="caption"> <span class='projecttitle'>Super Talent USB Drive Package.</span> A fancy, lavish package designed for Super Talent's specialty USB drive. It was known as the world's smallest flash drive <span class="amp">&amp;</span> it is dipped in gold! </div> </li> <li> <img src="images/portfolio/usbdrive/2.jpg" /> </li> <li> <img src="images/portfolio/usbdrive/3.jpg" /> </li> <li> <img src="images/portfolio/usbdrive/4.jpg" /> </li> <li> <img src="images/portfolio/usbdrive/5.jpg" /> </li> </ul> </div> <div class="thumbscontainer verticalthumbs"> <ul> <li><a href="javascript:void(0);" name="usbdrive1"><img src="images/portfolio/usbdrive/1.jpg" /></a></li> <li><a href="javascript:void(0);" name="usbdrive2"><img src="images/portfolio/usbdrive/2.jpg" /></a></li> <li><a href="javascript:void(0);" name="usbdrive3"><img src="images/portfolio/usbdrive/3.jpg" /></a></li> <li><a href="javascript:void(0);" name="usbdrive4"><img src="images/portfolio/usbdrive/4.jpg" /></a></li> <li><a href="javascript:void(0);" name="usbdrive5"><img src="images/portfolio/usbdrive/5.jpg" /></a></li> </ul> </div> </div>

  • adding a UITableView programmatically to a UIViewController

    - by Adam
    I'm loading a UIViewController into one of my Nav controller's hierarchies, which will contain some text and some images. At the bottom, I will want to create a expandable and collapsable tableview. First off, is this idea possible? If it is, how do I add it and where do I place the data source and delegate methods? Can I just make a separate subclass of the TableViewController and then add it to my ViewController as a subview?

  • Adding validations without knowing the fields

    - by Frexuz
    My example form <% form_for @ad do |f| %> <%= f.error_messages %> <p> <%= f.label :ad_type_id %><br /> <%= f.collection_select(:ad_type_id, AdType.all, :id, :name) %> </p> <p> <% @ad.ad_properties.each do |property| %> <%= property.name %>: <% f.fields_for :ad_values do |value_field| %> <%= value_field.text_field :ad_id, :value => @ad.id %> <%= value_field.text_field :ad_property_id, :value => property.id %> <%= value_field.text_field :value %> <% end %><br /><br /> <% end %> </p> <p> <%= f.label :description %><br /> <%= f.text_area :description %> </p> <p><%= f.submit %></p> <% end %> Explanation: Ad has many properties. I can add new properties at any time (it's a normal model). Lets say the Ad is of the type 'hotel'. Then I would add properties like 'stars' and 'breakfast_included' Then I store each of these properties' values in a separate model. And all this works fine with my form above. My problem: These fields are not validated because I can't know what their names are. I need to add validations dynamically somehow. My thought: #Before the normal validations kick in def add_validations self.properties.each do |property| property.add_validation :whatever #somehow :) end end How could I do this?

  • Adding Timestamp to Java's GC messages in Tomcat 6

    - by ripper234
    I turned on Java's GC log options -XX:+PrintGC -XX:+PrintGCTimeStamps -XX:+PrintGCDetails Which print out these messages to standard output (catalina.out): 314.884: [CMS-concurrent-mark-start] 315.014: [CMS-concurrent-mark: 0.129/0.129 secs] [Times: user=0.14 sys=0.00, real=0.13 secs] 315.014: [CMS-concurrent-preclean-start] 315.016: [CMS-concurrent-preclean: 0.003/0.003 secs] [Times: user=0.00 sys=0.00, real=0.00 secs] 315.016: [CMS-concurrent-abortable-preclean-start] 332.055: [GC 332.055: [ParNew: 17128K->84K(19136K), 0.0017700 secs] 88000K->70956K(522176K) icms_dc=4 , 0.0018660 secs] [Times: user=0.00 sys=0.00, real=0.00 secs] CMS: abort preclean due to time 352.253: [CMS-concurrent-abortable-preclean: 0.023/37.237 secs] [Times: user=0.78 sys=0.02, real=37.23 secs] How can I make these log lines appear with an actual timestamp (including date) instead of these numbers, which presumably mean "time since JVM started" ?

  • Failure when adding images to a thumbnail gallery

    - by Martin KS
    morning all, I've been browsing around trying to work out what I've done wrong when trying to add a thumbnail to a gallery view, but can't work out what on earth it might be. I'm trying to use the following code to stick a thumbnail onto a blank view: UIImageView *any = [[UIImageView alloc] initWithFrame:CGRectMake(a,b,70,60)]; any.image = [UIImage imageNamed:selectedThumbPath]; any.tag = 0; [self.view addSubview:any]; In the above example: a = 165 b = 150 selectedThumbPath = the full path to a thumbnail ie. /users/Cleverbum/library etc I'm pulling my hair out, there are no error messages, and no clues as to why it's not drawing anything. What's worse is that this is one of the only parts of the code i've not changed!

  • Multi-user job/task tracking/queue software

    - by Bmsgaffer86
    Background: I test and repair electronic products with a team. There are many 'jobs' going through my lab at any point in time. It is getting difficult to track whats coming in and going out because I don't do every test or repair myself. Target: User can enter a job when they drop it off in my lab, and it will appear on the master list or queue. Needs to have priorities and due dates that can be adjusted by users. Ideally this would be web based and open-source, but I am flexible. Dream: A large monitor displaying a list of jobs in the master queue with details. This is very optional though, and would be in the best case scenario. I have done MANY hours of Google-ing and I am not sure if I have been using the right terminology, but I have not found anything that is simple enough to stand alone yet complex enough to be multi-user based. I am mildly proficient in VB, and have the drive to piece anything together that I have to. I am open to ANY help or suggestions.
