• c# Crystal reports wait cursor

  - by Spooky2010

  Using vs2008, winforms C#. Im using the crystal reports version that comes with vs2008. I can create and load a crystal report ok. But becasue it can take a few minutes to load, i want to bring up a wait cursor, but am having trouble with that. I have tried setting the this.crystalReportViewer1.Cursor = Cursors.WaitCursor; and tried the parent form this.cursor = cursors.waitcursor; The cursor changes briefly to wait mode, then changes back before the report has finished loading.

• TToolButton Height Grows with Style = tbsDropdown

  - by smartins

  I noticed that the height of a TToolButton increases when you set the button's Style to tbsDropdown. I can understand the width increasing, so the button has space to draw the down arrow, but I'm not sure a height increase is necessary. Steps to reproduce the issue (Delphi 2010, Windows 7 x64): Add TToolbar to a form, ShowCaptions=True Right click to add a button to the Toolbar Set button Style=tbsDropDown and notice the button grows in height The same height increase happens when there are images assigned to the toolbar, in which case there is already plenty more vertical space available in the button to draw the drop down. Here's a visual example: Is there a workaround for this without hacking the VCL, or is this hardcoded into the Windows control?

• jquery - lose click() event after ajax call???

  - by niczoom

  At the following webpage liamharding.com/pgi.php I have an option panel on the left side of the page which opens and closes upon clicking the panels 'arrow', this works fine until you select a market (for testing use one of the 'Random Walk' markets and click 'Show/Refesh Graphs'), this then makes an ajax call using get_graph(forexName, myCount, divIsNew) function. Once this call is completed a graph(s) is displayed and then my options panels click() event does not work? The ajax call returns the data in a variable ajax_data, the problem happens when I perform the following code var jq_ajax_data = $("<div/>").html(ajax_data); . I need to wrap it in a so I can extract data from it using jQuery. If this line of code is commented out the click() event works fine ?? Hope somebody can help, I have spent a lot of time but cant find what the problem is.

• 2d parabolic projectile

  - by ndg

  I'm looking to create a basic Javascript implementation of a projectile that follows a parabolic arc (or something close to one) to arrive at a specific point. I'm not particularly well versed when it comes to complex mathematics and have spent days reading material on the problem. Unfortunately, seeing mathematical solutions is fairly useless to me. I'm ideally looking for pseudo code (or even existing example code) to try to get my head around it. Everything I find seems to only offer partial solutions to the problem. In practical terms, I'm looking to simulate the flight of an arrow from one location (the location of the bow) to another. It strikes me there are two distinct problems here: determining the position of interception between the projectile and a (moving) target, and then calculating the trajectory of the projectile. Any help would be greatly appreciated.

• How do you move the pointer up or down multiple lines with Emacs?

  - by Peter

  I can move my pointer up and down one line with my arrow key just fine in Emacs, so I'd like to redefine C-n and C-p to move up and down 5 lines at a time. I'm just beginning to learn how to use Emacs, and elisp is very alien to me. I tried using the GNU Emacs lisp reference, but I couldn't find how to bind a keystroke to multiple commands. Here's what I have so far (concentrating on the moving up definition): (global-set-key "\C-p" '(loop for i in '(1 2 3 4 5) do ('previous-line))) But, this brings up an error message when I hit C-p, "Wrong type argument." Any suggestions? Thanks!

• Can't get ScrollTo to work with keyboard arrows

  - by adamwstl

  I'm trying to setup the Jquery plugin SerialScroll with Ariel's added keyboard controls. I'm calling these three JS files: serialScroll.js scrollTo.js keyboard.js (the keyboard control snippet) Html I'm trying to manipulate. Want it to jump from ind-photo to ind-photo on arrow left and right. <div id="photos"> <div class="ind-photo"><img src="2.jpg" /></div> <div class="ind-photo"><img src="3.jpg" /></div> </div> I can't get it to work at all. I know there are likely slight things that are going to be off, but this isn't working at all. Thanks in advance.

• Styling WPF Toolkit DataGrid Column Headers

  - by ChrisFletcher

  Hi, I'm having an issue styling the WPF Datagrid, I've styled the column headers (of type ColumnHeader). But when the data in the columns does not fill the full width of the grid an additional column is added to pad out the grid. This column ignores the ColumnHeader style and looks out of place presumably because the element has a different type, I've looked through the library in object browser but I can't find this element. I've also considered fixing the sizes so this column is unnecessary but thats not a viable option. The problem is demonstrated in the following article: http://blogs.msdn.com/jaimer/archive/2009/01/20/styling-microsoft-s-wpf-datagrid.aspx The element I mean is in the top right, just to the right of green column 3 and just above the cell with the row background arrow.

• JQuery Autocomplete - Stop mouseover+Return submitting data

  - by ILT

  I'm using JQuery Autocomplete (bassistance) and have run into a problem. If the mouse rolls over one of the autocomplete suggestions and the user hits the return key (rather than clicking to make selection), the form is submitted and goes to whatever link was rolled over at the time. This is a problem as people click in the textbox, and when typing their search, leave the pointer where the autocomplete popup appears. So when they hit enter, it doesn't do the search for whatever they typed in the box but whatever was highlighted in the autocomplete suggestions. Is there a way to stop this? Using Google as the functionality I'm after... So just to clarify - I want selections via mouse and keyboard to go to the same place, but if the UP or DOWN arrow has not been pressed (user not selected an autocomplete option via the keyword), dont go to the URL specified in the autosuggest - instead submit the form (traditional method without JQuery) based on what has been typed in the textbox. I hope I'm explaining this clearly? :S

• jquery tabs changing on change?

  - by Steven

  Hello, I have two tabs each with different styles and different text. One recent posts and one recent comments the css for each are below with the ones I need to have when they are selected. So pretty much when a user selects the recent comments it will change the entire block to the second one (2). Pretty much changing width, and swapping the css for both tabs. I am currently using idtabs http://www.sunsean.com/idTabs/ My question: How can I have it change the tab css and width for both when the right tab is selected and then back again when the left tab is selected. CSS sideboxtopleft { float: left; width: 121px; height:20px; background-image: url(images/categorysplitter.gif); background-position:top right; background-repeat:no-repeat; text-align: center; padding-top: 10px; margin: 0; } sideboxtopleft2 { float: left; width: 173px; height:20px; background-image: url(images/categorysplitter.gif); background-position:top right; background-repeat:no-repeat; text-align: center; padding-top: 10px; margin: 0; } sideboxtopright { float: right; width: 173px; height: 20px; background-image:url(images/categorybg.gif); text-align: center; padding-top: 10px; margin: 0; } sideboxtopright2 { float: right; width: 121px; height: 20px; background-image:url(images/categorybg.gif); text-align: center; padding-top: 10px; margin: 0; } HTML <div id="sidebox" style="padding: 0px; width:294px;"> <div class="idTabs"> <div id="sideboxtopleft"> <a href="#post"><h3>RECENT POSTS <img src="images/arrow.gif" width="9" height="5" alt="v" border="0" /></h3></a> </div> <div id="sideboxtopright"> <a href="#comments"><h3>RECENT COMMENTS <img src="images/arrow2.gif" width="6" height="9" alt=">" border="0" /></h3></a> </div> </div> <div style="padding: 10px;"> <div id="post"> SUP? </div> <div id="comments"> SUP?>>!?>!! </div> </div> </div> <div id="sidebox" style="padding: 0px; width:294px;"> <div class="idTabs"> <div id="sideboxtopleft2"> <a href="#post2"><h3>RECENT COMMENTS <img src="images/arrow.gif" width="9" height="5" alt="v" border="0" /></h3></a> </div> <div id="sideboxtopright2"> <a href="#comments2"><h3>RECENT POSTS <img src="images/arrow2.gif" width="6" height="9" alt=">" border="0" /></h3></a> </div> </div> <div style="padding: 10px;"> <div id="post2"> SUP? </div> <div id="comments2"> SUP?>>!?>!! </div> </div> </div>

• When a template is rendered in template tag code, MEDIA_URL is not in context

  - by culebrón

  I want to use a template for 2 template tags. In the template, I used {{ MEDIA_URL }} and discovered that MEDIA_URL is not in context as expected. Had to use get_config and pass it manually. Why is the setting not in context, how else can I put it there, or maybe there's a better way that a template tag? (include, etc?) from django.template import Library from apps.annoying.functions import get_config from django.template.loader import render_to_string register = Library() @register.simple_tag def next_in_gallery(photo, gallery): next = photo.get_next_in_gallery(gallery) return make_arrow('right', next) @register.simple_tag def previous_in_gallery(photo, gallery): prev = photo.get_previous_in_gallery(gallery) return make_arrow('left', prev) def make_arrow(direction, object): return render_to_string('myapp/arrow.html', {'direction': direction, 'object': object, 'MEDIA_URL': get_config('MEDIA_URL', '')})

• Tooltip equivalent for touch devices?

  - by eteubert

  Hey folks, Touch devices are on the rise. More and more website developers try to optimize their pages for those devices. Until recently the most common solution was to build a mobile version for the website. But with tablets this will most likely change to adjusting the original pages to be touch compatible. One big issue I encountered are tooltips. There are some websites and web applications relying heavily on storing important informations in some kind of tooltip triggered by hovering the mouse arrow over some interface element - which does not exist on touch devices. So what do you think is a good universal way to adopt these pages without redesigning the site from scratch? Does this universal way even exist? My first idea was a tiny touchable question mark but this would hardly be big enough for a finger.

• When to use memberEnd and when navigableOwnedEnd (in Altova notation) in an UML class diagram?

  - by Ivan

  I've download a trial of Altova UModel and am starting using UML. As a practical beginning I am modelling a personal information manager application, which includes a web bookmark managing. A Bookmark can belong to many (or no) Tags at once and a Tag can contain many (or no if all the bookmarks it contained were deleted) bookmarks. The relation has to be both-way navigable - a user has to be able to see all Bookmarks with a particular Tags ans all Tags of a Bookmark. What is the correct UML relation between Bookmark and Tag classes? As far as I understand UML now, it is an Association (not an Aggregation). But for a 2-way navigable many-to-many relation I can specify ends roles as "memberEnd" or "when navigableOwnedEnd", graphically the connection looks the same in both cases (an arrow) (which as I understand means navigability) but a property appears in the class box in case only when "memberEnd" is used. How should I specif it in the model If I mean both-way navigable many-to-many relation there?

• Display fraction with numerator/denominator with empty fields for users to enter text

  - by Anil

  Hi all I have a scenario in which I need to design online keyboard with buttons implementing different mathematical functions in ASP.NET. For example 1) A button called "Fraction" Onclicking= should display A numerator and a denominator separated by '-' with empty fields. Just as we write fractions manually. Now when the user clicks on this button the cursor should focus on numerator displaying 'the division line' and then by pressing 'Down' arrow key(on computr keyboard) should focus on denominator allowing users to enter both fields. Keeping it simple the user should be able to toggle between numerator and denominator. Please help me with some sample code. I have got no idea. Thanks in advance

• .NET Ascertaining mouse is on line drawn between two arbitrary points

  - by johnc

  I have an arrow drawn between two objects on a Winform. What would be the simplest way to determine that my mouse is currently hovering over, or near, this line. I have considered testing whether the mouse point intersects a square defined and extrapolated by the two points, however this would only be feasible if the two points had very similar x or y values. I am thinking, also, this problem is probably more in the realms of linear algebra rather than simple trigonometry, and whilst I do remember the simpler aspects of matrices, this problem is beyond my knowledge of linear algebra. On the other hand, if a .NET library can cope with the function, even better.

• scrolling a readonly cell in NSTableview?

  - by John Velman

  I have a table that the user should not be able to edit directly (although user actions may cause changes). One column may contain a string too long for any reasonable size cell, so to see everything there, the user needs to scroll the cell (using arrow keys, for example). If I make either the column or cell not editible, I loose the ability to scroll the cell. If I make it editable, of course, I loose the ability to keep the user from changeing it. (I'm using NSArray controller and a couple of NSObject controllers to get from the model to the table view using bindings. Binding compliance via @property(copy) and @synthesize. Updating the model with setXXXX:xxx). Thanks, John Velman

• How to reference an object in a lower fragment in android

  - by Silas Greenback

  I am trying to build a help screen that is going to go on a mediaplayer. The idea is to put a fragment with a transparent theme on top of the current view. (See How do I create a help overlay like you see in a few Android apps and ICS? for the basic idea). Now, I understand the steps in the mentioned link, but how do I connect the circles and arrows and paragraphs next to each one (explaining what each one was) to the lower object? Example, I have an object: R.id.music_button and I want there to be and arrow that points to music button. Trying to support as many devices as we do it will be very difficult to just draw a few pictures as part of the top layout and expect them to line up. Again, how do I reference an object on a fragment below the top level? Thanks

• CSS3: Top align of list item

  - by Irishgirl

  CSS3: Top align of list item. See image as below. How can I align a blue arrow to align on top of a senetence of each list. I'm using jQuery 1.7 and it is for iOS (iPhone). ul.lists{ padding:0 0 15px 0;} ul.lists li{ line-height:18px; border-bottom:1px #bfeaf0 solid; padding:6px 12px; background:url(../images/arrow_cyan.svg) no-repeat left; } /* no-repeat left top; */ I've tried to include a js as offset $("li:last").offset({ top: -15 }); but it did not work properly because I don't know how to move all blue arrows to align each list even the sentence might might run into more than one line.

• How to capture the value change of numericUpDown ctrl real-time in .NET?

  - by Carlos_Liu

  I have implement the ValueChanged event, but I found it will be triggered only after change the focus from numericUpDown to other control or by clicking the up/down arrow. Inputting the value in the control will not trigger ValueChanged event. What I did now is adding an KeyDown event and judge if the input value is numeric (can not include SHIFT/CTRL/ALT key); but there is another case need to be involved: the user can paste value into the numericUpDown ctrl What I need is : When I was typing numeric value (only numeric) in the numericUpDown ctrl, it will known the content has been changed; When pasted a numeric value into the ctrl, it also kowns the content changed

• Self-expanding Widget, on mouse over

  - by Sergiy Migdalskiy

  I want to implement a widget (with some edit boxes and sliders) that would open beneath or next to a button ("Opener") when I hover it. The key is it's a temporary widget - as soon as it loses focus, I want it gone. Also, I want it to pop up right next to the Opener, ideally pointing an arrow to Opener. So, it's basically a tooltip. But it needs to be a widget with buttons and sliders and stuff like that. Is there a clever way to implement it without making a custom widget and writing handlers for all the mouse and focus events and recomputing its ideal position every time I open it or the Opener moves?

• Initial state of autoCreateRowSorter in Swing JTable

  - by Nazgulled

  I have this JTable on my Swing app with the autoCreateRowSorter enabled. My table only has 3 columns, two strings and one int, it works well for all of them when I click the column headers. However, I'm looking for way to do it programatically. I wanted to set the "initial state" for this table. With the Windows look and feel, the column header (when sorted) has a little arrow showing the sort order. But at startup that doesn't show, I have to do one initial click. How can I do that by code?

• Looking for a Silverlight 3 or 4 Menu control providing decent keyboard support.

  - by Geo

  I've an N-Tier application using Silverlight for the client. The customer as one particular request - I thought was more than reasonable: all actions – including menu navigation – has to be available through keyboard. When I tried Silverlight 4 I was surprised not to find any menu control so I downloaded several open source and commercial menu controls. I was very disappointed, after having searched for a couple of hours I didn’t manage to find any control that provide a decent keyboard support. Most controls provide no support or some basic support but not one control enabled to gain focus on the first item through the keyboard. You are able to use the keyboard (arrow keys) but you need first to select the control with the mouse! Not one control provided support for Keyboard shortcuts. Does anyone know of any Silverlight control providing descent support?

• IntelliJ Split Window Navigation

  - by jmquigley

  If I split the editor window (horizontal or vertical) into N tab groups, how do I switch/toggle from one tab group to another via the keyboard? If all of the tabs are in the same group you can switch from each tab easily (CTRL + right/left arrow), but when they're in separate tab groups I can't. I've searched through the key mappings and have not found one that seems to accomplish this. I know I can use the mouse, but I'm trying to find ways to avoid the mouse and stay with the keyboard. TIA for any help on this.

• LINQ, creating unique collection of a collection

  - by Wish

  I have class Vertex and a class Edge (Edge holds 2 properties - Vertex Source and Vertex Target); Edges and Vertexes are collected into lists Some example: A-->B // edge from vertex A to B B-->C // edge from vertex B to C C-->A // edge from vertex C to A A-->C // edge from vertex A to C -- this is two way edge So I would like to make IDictionary<Edge, bool> which would hold edges (A--B and B--A would be like 1), and bool - if it is two way or no. I need it because when I draw them now, it draws 2 arrows under one another. I would better make 1 arrow. So I'm pretty stuck right here... May anybody help me a bit ?
