• Combine NotifyIcon and ToolTip

  - by Greycrow

  I have been working with NotifyIcon in order to show an icon in the taskbar. This program has no Windows Form. I perhaps could create one and make it invisible but I was hoping to avoid it. The ToolTip functions attached to NotifyIcon are somewhat lacking, and one of the gurus here suggested I look at the ToolTip functionality. It is possible to attach ToolTip to a form. Is is possible to attach it to just the NotifyIcon? I'm trying do this: NotifyIcon CTicon = new NotifyIcon(); ToolTip toolTip = new ToolTip(); toolTip.SetToolTip(CTicon, "Test"); And I get the error "cannot convert from 'System.Windows.Forms.NotifyIcon' to 'System.Windows.Forms.Control'. Is there a way to convert? I also tried: toolTip.SetToolTip(CTicon.Container, "Test"); but a container is apparently not a valid control either. I apologize for my total lack of understanding of how this may or may not work. Thanks in advance.

• UIView Animation animates position but not width

  - by Aaron Vegh

  Hi there, I'm trying to transform a UISearchBar, like in Mobile Safari: touch in the search field and it grows while the location field shrinks. My current animation to alter the width and position of the search field only animates the position: just before it slides to the right place, it simply snaps out to the right width. Here's my code: [UIView beginAnimations:@"searchGrowUp" context:nil]; [UIView setAnimationCurve:UIViewAnimationCurveEaseIn]; [UIView setAnimationDuration:0.5f]; [UIView setAnimationDelegate:self]; CGFloat findFieldWidth = findField.frame.size.width; CGFloat urlFieldWidth = urlField.frame.size.width; CGRect findFieldFrame = findField.frame; CGRect urlFieldFrame = urlField.frame; findFieldFrame.origin.x = findFieldFrame.origin.x - 150.0f; findFieldFrame.size.width = findFieldWidth + 150.0f; urlFieldFrame.size.width = urlFieldWidth - 150.0f; urlField.frame = urlFieldFrame; findField.frame = findFieldFrame; [UIView commitAnimations]; I've modified this code slightly for the sake of presenting it here, but I hope this gives the gist. Any guesses as to why this is happening would be appreciated! Cheers, Aaron.

• Math operations in nHibernate Criteria Query

  - by Richard Tasker

  Dear All, I am having troubles with a nHibernate query. I have a db which stores vehicle info, and the user is able to search the db by make, model, type and production dates. Make, model & type search is fine, works a treat, it is the productions dates I am having issues with. So here goes... The dates are stored as ints (StartMonth, StartYear, FinishMonth, FinishYear), when the end-user selects a date it is passed to the query as an int eg 2010006 (2010 * 100 + 6). below is part of the query I am using, FYI I am using Lambda Extensions. if (_searchCriteria.ProductionStart > 0) { query.Add<Engine>(e => ((e.StartYear * 100) + e.StartMonth) >= _searchCriteria.ProductionStart); } if (_searchCriteria.ProductionEnd > 0) { query.Add<Engine>(e => ((e.FinishYear * 100) + e.FinishMonth) <= _searchCriteria.ProductionEnd); } But when the query runs I get the following message, Could not determine member from ((e.StartYear * 100) + e.StartMonth) Any help would be great, Regards Rich

• OCS presence in SharePoint AJAX-based web part

  - by Maksym Ozerov

  I'm currently implementing AJAX-based web part which displays search result. This search result has user names and opposite to each name I'm rendering the OCS presence indicator. This indicator works fine in IE6 but I can't get it to work in IE7/8. Basically the problem in IE7/8 is that OCS is rendered but when you mouse over it nothing is shown. If you try to scroll page down then mouse over the OCS icon you will see the OCS actions menu in the bottom of the page instead of seeing it on the opposite to the user name. My AJAX-based web part uses jQuery post method to make a request to the server and receives json which is then rendered to the div. My HTML for the user name looks like this: <nobr> <span> <a target='_blank' href='/ViewExpert.aspx?uid=4'>Some Expert</a> <img height='1' width='3' border='0' alt='' src='/_layouts/images/blank.gif'><a class='ms-imnlink' onclick='IMNImageOnClick();return false;' href='javascript:'> <img height='12' width='12' border='0' id='3' ShowOfflinePawn='1' type='smtp' sip='[email protected]' src='/_layouts/images/blank.gif' valign='middle' name='imnmark' alt='No presence information' title=''> </a> </span> </nobr> After the HTML above is rendered on the page I call the following two lines of code: //have to reset this value, otherwise ProcessImn() fails after next AJAX request imnCount = 0; ProcessImn(); Any ideas why it doesn't work in IE7/8?

• How to improve the use of Delphi Frames

  - by Brian Frost

  I've used frames in Delphi for years, and they are one of the most powerful features of the VCL, but standard use of them seems to have some risk such as: It's easy to accidentally move or edit the frame sub-components on a frame's host form without realising that you are 'tweaking' with the frame - I know this does not affect the original frame code, but it's generally not what you would want. When working with the frame you are still exposed to its sub-components for visual editing, even when that frame is years old and should not be touched. So I got to thinking.... Is there a way of 'grouping' components such that their positions are 'locked'? This would be useful for finished forms as well as frames. Often other developers return code to me where only the form bounds have changed and even they did not intend any change. Is there any way of turning a frame and its components into a single Delphi component? If so, the frame internals would be completely hidden and its useability would increase further. I'm interested in any thoughts... Brian.

• Thinking sphinx: Problems with polymorphic associations

  - by auralbee

  Hello, I recently switched from ultrasphinx to thinking_sphinx for full-text search. I am trying to figure out how to index fields of polymorphic associations. I found some information but I still have some problems, although it seems to be easy. Here is my setup: class Info < ActiveRecord::Base belongs_to :mappable, :polymorphic => true define_index indexes mappable_type indexes mappable(:name), :as => :mappable_name end class A < ActiveRecord::Base has_many :infos, :as => :mappable end class B < ActiveRecord::Base has_many :infos, :as => :mappable end Amongst others, I want to do a search in the name column of A and B (both classes have this column), so I added the field to my index. When I do rake thinking_sphinx:index I get the following error: Generating Configuration to .../config/development.sphinx.conf rake aborted! undefined method `connection' for Object:Class .../.gem/ruby/1.8/gems/thinking-sphinx-1.3.16/lib/thinking_sphinx/ association.rb:149:in `casted_options' Any idea? Am I missing something? Thanks in advance. Tobi

• JSF 2.0: Validate equality of 2 InputSecret Fields (confirm password) without writing Code?

  - by yournamehere

  I'm developing a pure JavaEE6 application with JSF 2.0 and Glassfish. My JSF implementation is Primefaces (beside Mojarra provided by Glassfish). I want to verify if the values of 2 password fields in a JSF form are equal. With Seam, there is the neat component <s:validateEquality for="pw1"/>. I want do to the same without Seam, just using JSF (or maybe a component of a JSF library). Until now i only saw examples which validate the form with a custom validator. But i would like to compare the fields without writing Java code or Javascript code. Is that possible? This what it looks like with Seam: ... <h:inputSecret id="passwort" value="#{personHome.instance.password}" redisplay="true" required="true"> <f:validateLength minimum="8"/> <a:support event="onblur" reRender="passwortField" bypassUpdates="true" ajaxSingle="true" /> </h:inputSecret> ... <h:inputSecret id="passwort2" required="true" redisplay="true"> <!-- find the JSF2.0-equivalent to this tag: --> <s:validateEquality for="passwort"/> <a:support event="onblur" reRender="passwort2Field" bypassUpdates="true" ajaxSingle="true" /> </h:inputSecret> ... Any help is appreciated. Thanks!

• Why ComboBox hides cursor when DroppedDown is set?

  - by Ivan Danilov

  Let's create WinForms Application (I have Visual Studio 2008 running on Windows Vista, but it seems that described situation takes place almost everywhere from Win98 to Vista, on native or managed code). Write such code: using System; using System.Drawing; using System.Windows.Forms; namespace WindowsFormsApplication1 { public class Form1 : Form { private readonly Button button1 = new Button(); private readonly ComboBox comboBox1 = new ComboBox(); private readonly TextBox textBox1 = new TextBox(); public Form1() { SuspendLayout(); textBox1.Location = new Point(21, 51); button1.Location = new Point(146, 49); button1.Text = "button1"; button1.Click += button1_Click; comboBox1.Items.AddRange(new[] {"1", "2", "3", "4", "5", "6"}); comboBox1.Location = new Point(21, 93); AcceptButton = button1; Controls.AddRange(new Control[] {textBox1, comboBox1, button1}); Text = "Form1"; ResumeLayout(false); PerformLayout(); } private void button1_Click(object sender, EventArgs e) { comboBox1.DroppedDown = true; } } } Then, run app. Place mouse cursor on the form and don't touch mouse anymore. Start to type something in TextBox - cursor will hide because of it. When you press Enter key - event throws and ComboBox will be dropped down. But now cursor won't appear even if you move it! And appears only when you click somewhere. There I've found discussion of this problem. But there's no good solution... Any thoughts? :)

• How to determine if DataGridView contains uncommitted changes when bound to a SqlDataAdapter

  - by JYelton

  I have a form which contains a DataGridView, a BindingSource, a DataTable, and a SqlDataAdapter. I populate the grid and data bindings as follows: private BindingSource bindingSource = new BindingSource(); private DataTable table = new DataTable(); private SqlDataAdapter dataAdapter = new SqlDataAdapter("SELECT * FROM table ORDER BY id ASC;", ClassSql.SqlConn()); private void LoadData() { table.Clear(); dataGridView1.AutoGenerateColumns = false; dataGridView1.DataSource = bindingSource; SqlCommandBuilder commandBuilder = new SqlCommandBuilder(dataAdapter); table.Locale = System.Globalization.CultureInfo.InvariantCulture; dataAdapter.Fill(table); bindingSource.DataSource = table; } The user can then make changes to the data, and commit those changes or discard them by clicking either a save or cancel button, respectively. private void btnSave_Click(object sender, EventArgs e) { // save everything to the displays table dataAdapter.Update(table); } private void btnCancel_Click(object sender, EventArgs e) { // alert user if unsaved changes, otherwise close form } I would like to add a dialog if cancel is clicked that warns the user of unsaved changes, if unsaved changes exist. Question: How can I determine if the user has modified data in the DataGridView but not committed it to the database? Is there an easy way to compare the current DataGridView data to the last-retrieved query? (Note that there would not be any other threads or users altering data in SQL at the same time.)

• Why is PHP not allowing comparison?

  - by dcp3450

  I'm using PHP to read if an entry in my table on the database is set to "yes" or "no" and auto check the radio button that corresponds: <?php include 'file.php'; $query = "SELECT * FROM TABLE"; $runquery = odbc_exec($connect,$query); $status= odbc_result($runquery,"status"); odbc_close($file); ?> <form> <div class="formContainer"> <fieldset> <legend>Campus Alert<span class="tooltip">Turn campus alert on and off.</span></legend> <?php echo $status; ?> Yes <input type="radio" name="alertStatus" id="alertStatus" value="yes" <?php if($status== "yes") echo "checked";?>> No <input type="radio" name="alertStatus" id="alertStatus" value="no" <?php if($status== "no") echo "checked";?>> </fieldset> </div> the is for debugging so I can make sure what the database says and the form's reaction is correct. It prints "yes" (no quotes). However, the if statement will not respond. Any idea why it's doing this?

• Styling an Input Field

  - by John

  Hello, How can I give the input field below the characteristics listed below? Characteristics: -Text typed into the field starts in the upper left corner and starts on another line (wraps?) when the right border of the field is reached. -A scroll bar appears if the text is more than what can fit into the field. -The text is in Courier font. Thanks in advance, John echo '<form action="http://www...com/sandbox/comments/comments2.php" method="post"> <input type="hidden" value="'.$_SESSION['loginid'].'" name="uid"> <input type="hidden" value="'.$submissionid.'" name="submissionid"> <input type="hidden" value="'.$submission.'" name="submission"> <label class="addacomment" for="title">Add a comment:</label> <input class="commentsubfield" name="comment" type="comment" id="comment" maxlength="1000"> <div class="commentsubbutton"><input name="submit" type="submit" value="Submit"></div> </form> '; Some relevant CSS: .commentsubfield {margin-left: 30px; margin-top: 30px; width: 390px; height: 90px; border: 1px solid #999999; padding: 5px; }

• Grails - Simple hasMany Problem - How does 'save' work?

  - by gav

  My problem is this: I want to create a grails domain instance, defining the 'Many' instances of another domain that it has. I have the actual source in a Google Code Project but the following should illustrate the problem. class Person { String name static hasMany[skills:Skill] static constraints = { id (visible:false) skills (nullable:false, blank:false) } } class Skill { String name String description static constraints = { id (visible:false) name (nullable:false, blank:false) description (nullable:false, blank:false) } } If you use this model and def scaffold for the two Controllers then you end up with a form like this that doesn't work; My own attempt to get this to work enumerates the Skills as checkboxes and looks like this; But when I save the Volunteer the skills are null! This is the code for my save method; def save = { log.info "Saving: " + params.toString() def skills = params.skills log.info "Skills: " + skills def volunteerInstance = new Volunteer(params) log.info volunteerInstance if (volunteerInstance.save(flush: true)) { flash.message = "${message(code: 'default.created.message', args: [message(code: 'volunteer.label', default: 'Volunteer'), volunteerInstance.id])}" redirect(action: "show", id: volunteerInstance.id) log.info volunteerInstance } else { render(view: "create", model: [volunteerInstance: volunteerInstance]) } } This is my log output (I have custom toString() methods); 2010-05-10 21:06:41,494 [http-8080-3] INFO bumbumtrain.VolunteerController - Saving: ["skills":["1", "2"], "name":"Ian", "_skills":["", ""], "create":"Create", "action":"save", "controller":"volunteer"] 2010-05-10 21:06:41,495 [http-8080-3] INFO bumbumtrain.VolunteerController - Skills: [1, 2] 2010-05-10 21:06:41,508 [http-8080-3] INFO bumbumtrain.VolunteerController - Volunteer[ id: null | Name: Ian | Skills [Skill[ id: 1 | Name: Carpenter ] , Skill[ id: 2 | Name: Sound Engineer ] ]] Note that in the final log line the right Skills have been picked up and are part of the object instance. When the volunteer is saved the 'Skills' are ignored and not commited to the database despite the in memory version created clearly does have the items. Is it not possible to pass the Skills at construction time? There must be a way round this? I need a single form to allow a person to register but I want to normalise the data so that I can add more skills at a later time. If you think this should 'just work' then a link to a working example would be great. Hope this makes sense, thanks in advance! Gav

• How do you determine subtype of an entity using Inheritance with Entity Framework 4?

  - by KallDrexx

  I am just starting to use the Entity Framework 4 for the first time ever. So far I am liking it but I am a bit confused on how to correctly do inheritance. I am doing a model-first approach, and I have my Person entity with two subtype entities, Employee and Client. EF is correctly using the table per type approach, however I can't seem to figure out how to determine what type of a Person a specific object is. For example, if I do something like var people = from p in entities.Person select p; return people.ToList<Person>(); In my list that I form from this, all I care about is the Id field so i don't want to actually query all the subtype tables (this is a webpage list with links, so all I need is the name and the Id, all in the Persons table). However, I want to form different lists using this one query, one for each type of person (so one list for Clients and another for Employees). The issue is if I have a Person entity, I can't see any way to determine if that entity is a Client or an Employee without querying the Client or Employee tables directly. How can I easily determine the subtype of an entity without performing a bunch of additional database queries?

• How to do custom display and auto-select in django admin multi-select field?

  - by rsp

  I'm new to django, so please feel free to tell me if I'm doing this incorrectly. I am trying to create a django ordering system. My order model: class Order(models.Model): ordered_by = models.ForeignKey(User, limit_choices_to = {'groups__name': "Managers", 'is_active': 1}) in my admin ANY user can enter an order, but ordered_by must be someone in the group "managers" (this is the behavior I want). Now, if the logged in user happens to be a manager I want it to automatically fill in the field with that logged in user. I have accomplished this by: class OrderAdmin(admin.ModelAdmin): def formfield_for_foreignkey(self, db_field, request, **kwargs): if db_field.name == "ordered_by": if request.user in User.objects.filter(groups__name='Managers', is_active=1): kwargs["initial"] = request.user.id kwargs["empty_label"] = "-------------" return db_field.formfield(**kwargs) return super(OrderAdmin, self).formfield_for_foreignkey(db_field, request, **kwargs) This also works, but the admin puts the username as the display for the select box by default. It would be nice to have the user's real name listed. I was able to do it with this: class UserModelMultipleChoiceField(forms.ModelMultipleChoiceField): def label_from_instance(self, obj): return obj.first_name + " " + obj.last_name class OrderForm(forms.ModelForm): ordered_by = UserModelChoiceField(queryset=User.objects.all().filter(groups__name='Managers', is_active=1)) class OrderAdmin(admin.ModelAdmin): form = OrderForm My problem: I can't to both of these. If I put in the formfield_for_foreignkey function and add form = OrderForm to use my custom "UserModelChoiceField", it puts the nice name display but it won't select the currently logged in user. I'm new to this, but my guess is that when I use UserModelChoiceField it "erases" the info passed in via formfield_for_foreignkey. Do I need to use the super() function somehow to pass on this info? or something completely different?

• Textbox autofill not in correct position in safari

  - by jerjer

  Hello All, Has anyone experience this weird issue on safari? Textbox autofill is not at its correct position, please see screenshot below. I have been searching for answers in google for almost a day, still no luck. This is the built-in autofill feature of safari. Here is the markup: index.php <html> <body> <div id="nav"></div> <div id="content"> <iframe style="width:100%;height:100%" src="add_user.php" frameborder="0"></iframe> </div> .... </body> </html> add_user.php <html> .... <body> <form method="post"> <h3>Add User (Admin only) <div id="msg">Please enter First and Last Name.</div> <ul> <li><label>* Email</label> <input type="text" id="email" /></li> <li><label>* First Name</label> <input type="text" id="fname" /></li> <li><label>* Last Name</label> <input type="text" id="lname" /></li> .... </ul> </form> </body> </html> I am suspecting that this is caused by the iframe, but it works just fine in other browsers. Also I could not change the page design(using iframe) right away for practical reasons. Thanks

• TinyMCE + jQuery + custom plugin = tinymce is undefined?

  - by user368691

  The problem occurs when I try to create small plugin to allow me toggle on and off WYSIWYG on all textareas in the website. //$('form.default textarea').each(function(){ // console.log( $('<a href="#">Enable WYSIWYG editor</a>').insertAfter('form.default textarea').prev('textarea.wysiwyg').tinymce().hide() ); //}); The full (a bit simplified) code looks like this: $('textarea.wysiwyg').tinymce({ skin : 'cirkuit', theme : 'advanced', plugins : 'pagebreak,style,layer,advlink,inlinepopups,contextmenu,paste,directionality,noneditable,nonbreaking,xhtmlxtras,template', // Theme options theme_advanced_buttons1 : 'formatselect,fontsizeselect,forecolor,|,bold,italic,strikethrough,|,bullist,numlist,|,justifyleft,justifycenter,justifyright,|,link,unlink,|,image,|,code,paste,pastetext,pasteword,removeformat,|,backcolor,|,underline,justifyfull,sup,|,outdent,indent,|,hr,charmap,|,undo,redo', theme_advanced_buttons2 : '', theme_advanced_buttons3 : '', theme_advanced_toolbar_location : 'top', theme_advanced_toolbar_align : 'left', theme_advanced_statusbar_location: 'bottom', theme_advanced_resizing : true, theme_advanced_resize_horizontal : false, height : 500, theme_advanced_resizing_min_height : 500, document_base_url : 'http://static.<?=$settings['system_host']?>/' }); $('textarea.wysiwyg').each(function() { $(this).tinymce().hide(); }); What is the error? FireBug says that tinymce() in undefined; this message occurs in each() loop. Thus, tinymce() is actually initialized. I am really lost towards, what could be causing this.

• Find unique vertices from a 'triangle-soup'

  - by sum1stolemyname

  I am building a CAD-file converter on top of two libraries (Opencascade and DWF Toolkit). However, my question is plattform agnostic: Given: I have generated a mesh as a list of triangular faces form a model constructed through my application. Each Triangle is defined through three vertexes, which consist of three floats (x, y & z coordinate). Since the triangles form a mesh, most of the vertices are shared by more then one triangle. Goal: I need to find the list of unique vertices, and to generate an array of faces consisting of tuples of three indices in this list. What i want to do is this: //step 1: build a list of unique vertices for each triangle for each vertex in triangle if not vertex in listOfVertices Add vertex to listOfVertices //step 2: build a list of faces for each triangle for each vertex in triangle Get Vertex Index From listOfvertices AddToMap(vertex Index, triangle) While I do have an implementation which does this, step1 (the generation of the list of unique vertices) is really slow in the order of O(n!), since each vertex is compared to all vertices already in the list. I thought "Hey, lets build a hashmap of my vertices' components using std::map, that ought to speed things up!", only to find that generating a unique key from three floating point values is not a trivial task. Here, the experts of stackoverflow come into play: I need some kind of hash-function which works on 3 floats, or any other function generating a unique value from a 3d-vertex position.

• Get coordinates of google maps markers

  - by App_beginner

  I am creating a databse containing the names and coordinates of all bus stops in my local area. I have all the names stored in my database, and now I need to add the coordinates. I am trying to get these of a website that contains them all as placemarks on a google map. It seems to me like they are being generated from a local server, and then added to the map. However I am unable to find exactly where the server is queried for the coordinates. I am hoping to collect these coordinates through the use of a screen scraper. However unless I am able to find where in the source code the coordinates are created this seems to be impossible. I can of course search and collect all these placemarks manually, but that will be very time consuming. So I am hoping that someone in here can help me. This is the website I am trying to scrape. The placemarks are marked by the blue bus sign: http://reiseplanlegger.skyss.no/scripts/travelmagic/TravelMagicWE.dll/?from=Brimnes+ferjekai+%28Eidfjord%29&to= You can also get the coordinates of a single placemark by writing the name of the stop in the search field and pushing the "Vis i kart" button. I hope someone can help me with this.
