• Setting QTMovie attributes

  - by Josh Matthews

  I'm trying to create a QTVR movie via QTKit, and I've got all the frames in the movie. However, setting the attributes necessary doesn't seem to be having any effect. For example: NSNumber *val = [NSNumber numberWithBool:YES]; [fMovie setAttribute:val forKey:QTMovieIsInteractiveAttribute]; val = [NSNumber numberWithBool:NO]; [fMovie setAttribute:val forKey:QTMovieIsLinearAttribute]; If I then get the value of these attributes, they come up as NO and YES, respectively. The movie is editable, so I can't understand what I'm doing wrong here. How can I ensure that the attributes will actually change?

• Is there a reliable way to activate / set focus to a window using C#?

  - by gtaborga

  Hey everyone, I'm trying to find a reliable way to activate / set focus a window using C#. Currently I'm attempting to achieve this using the following Windows API calls: SetActiveWindow(handle); SwitchToThisWindow(handle, true); Previously I also had ShowWindow(handle, SW_SHOWMAXIMIZED); executing before the other 2, but removed it because it was causing strange behavior. The problem I'm having with my current implementation is that occasionally the focus will not be set correctly. The window will become visible but the top part of it will still appear grayed out as if it wasn't in focus. Is there a way to reliably do this which works 100% of the time, or is the inconsistent behavior a side-effect I can't escape? Please let me know if you have any suggestions or implementations that always work. Thank you for your time.

• mysql_close(): supplied argument is not a valid MySQL-Link resource

  - by Illes Peter

  Here's what I'm trying to do: I've got a db.php file that does all the db manipulation. It has 2 static methods, connect and deconnect. In my other file i simply use db::connect() and db::deconnect(). The mysql_close($con) in the deconnect method just doesn't know who $con is. Since I don't want to instantiate my class static is the only way to go. Declaring 'private $con' in class db doesn't seem to have an effect. Any ideas? class db { public static function connect() { $dbData = parse_ini_file($_SERVER['DOCUMENT_ROOT'].'/config.ini'); $con = mysql_connect($dbData['host'],$dbData['user'],$dbData['pass']); $db = mysql_select_db($dbData['db']); if ((!$con) || (!$db)) return 0; else return 1; } public static function deconnect() { mysql_close($con); } }

• Excel 2007 - Worksheet is larger than the window

  - by Chris

  Hi This is an odd problem but frustrating none the less. I have a worksheet saved which is larger than the Excel 2007 "workarea". This means when I open the worksheet I cannot access the corners of the worksheet to reduce the size and the worksheets title bar area (with move,size,minimise etc) is hidden beneath the ribbon , even if I remove the ribbon , I still can't see the title bar. In Excel 2003 I've had a similar effect but I've always been able to hit the "alt" key to access the "Move" option. However in Excel 2007 , hitting "alt" brings up some shortcuts for the ribbon etc but I can't access the worksheet options. Has anyone else know how to access the worksheet drop down when this happens?

• Can't get ellipsis to work on Android

  - by Mark

  Hi, I have a TextView. I want it to ellipsize if longer than its available width. This does not work unless the input string has no spaces... can anyone provide an example of this working? I've tried different combinations of: singleLine="true" maxLines="1" scrollHorizontally="false" none of these have any effect. Again, if I supply a string that has no spaces in it, then the ellipsis appears correctly. What am I missing? I've tried this on 1.5, 1.6, 2.0, all same problem. Thanks

• assignment vs std::swap and merging and keeping duplicates in seperate object

  - by rubenvb

  Say I have two std::set<std::string>s. The first one, old_options, needs to be merged with additional options, contained in new_options. I can't just use std::merge (well, I do, but not only that) because I also check for doubles and warn the user about this accordingly. To this effect, I have void merge_options( set<string> &old_options, const set<string> &new_options ) { // find duplicates and create merged_options, a stringset containing the merged options // handle duplicated the way I want to // ... old_options = merged_options; } Is it better to use std::swap( merged_options, old_options ); or the assignment I have? Is there a better way to filter duplicates and return the merged set than consecutive calls to std::set_intersection and std::set_union to detect dupes and merge the sets? I know it's slower than one traversal and doing both at once, but these sets are small (performance is not critical) and I trust the Standard more than I trust myself.

• Animated record deletion with jquery like mootools example

  - by twitter

  I was reading around and saw this example from David Walsh about how to animate record deletion with mootools. Does the exact same effect exist in jquery? This is his mootools code. window.addEvent('domready',function() { $$('a.delete').each(function(el) { el.addEvent('click',function(e) { e.stop(); var parent = el.getParent('div'); var request = new Request({ url: 'mootools-record-delete.php', link: 'chain', method: 'get', data: { 'delete': parent.get('id').replace('record-',''), ajax: 1 }, onRequest: function() { new Fx.Tween(parent,{ duration:300 }).start('background-color', '#fb6c6c'); }, onSuccess: function() { new Fx.Slide(parent,{ duration:300, onComplete: function() { parent.dispose(); } }).slideOut(); } }).send(); }); }); });

• How to set attribs in GWT?

  - by Jonas Byström

  I'm not getting any effect out of DOM.setElementAttribute, am I doing something wrong? class MyListBox extends com.google.gwt.user.client.ui.ListBox { .... protected void setHoverAutoWidth() { addDomHandler(new MouseOverHandler() { public void onMouseOver(MouseOverEvent event) { DOM.setElementAttribute(getElement(), "width", "auto"); } }, MouseOverEvent.getType()); addDomHandler(new BlurHandler(){ public void onBlur(BlurEvent event) { DOM.setElementAttribute(getElement(), "width", "100px"); } }, BlurEvent.getType()); } } (I know there are less hacky ways to change the width than to set the style attribute directly, but I don't care about css right now.) Edit: Oops, just realized that width does not change the style width, just adds a width attribute to the tag (which explains why nothing happens). Any suggestions on how to modify the style are still welcome!

• How to vertically align an inline image with inline text following it?

  - by amn

  Is there any way to vertically align an image element generated by a "content" property as part of a ":before" selector, next to adjacent inline text? In other words, I have <a href="..." class="facebook">Share on Facebook</a> As I don't want to pollute my markup with unnecessary IMG elements that only have to do with style, I resort to adding a small icon to the left of the link, via CSS (except that it does not align properly, hence the question): a.facebook:before { content: url(/style/facebook-logo.png); } I tried adding a "vertical-align: middle" (one of the most notoriously difficult aligning concepts to grasp in CSS, in my opinion, is that very property) but it has no effect. The logo aligns with text baseline, and I don't want to hardcode pixel offsets, because frankly text size differs from browser to browser, etc. Is there any solution for this? Thanks.

• Why are all my masked views unmasked in my view snapshot?

  - by mystify

  I'm taking a snapshot of an view. This view has got some subviews which have layer masks applied to them. For some reason, those masks take no effect in the snapshot and the masked parts are completely visible. UIGraphicsBeginImageContext(theView.frame.size); [theView.layer renderInContext:UIGraphicsGetCurrentContext()]; UIImage *newImage = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); I assume this is a bug in the framework. But maybe it's not? Did I do anything wrong here?

• Where's the font setting for folders in the Package Explorer?

  - by Carl Smotricz

  I'm talking about Eclipse (3.5 = Galileo), running under Kubuntu 9.10 and I have the Subversive plugin. I've been moved from Gnome-Ubuntu to Kubuntu, and one side effect was that some fonts are now just too tiny to read. File names in the explorer have a decent size, but folders are shown in a too-small font, and after having adjusted all the fonts in General|Appearance|Colors and Fonts the folders are unchanged. Maybe I'm just blind. I'd appreciate it if someone could point me to where I can adjust the font for folders in the Package Explorer

• How to color a mesh with values at the vertices in WPF 3D?

  - by Christo

  We've got a sphere which we want to display in 3D and color given a fuction that depends on spherical coordinates. The sphere was triangulated using a regular grid in (theta, phi), but this produced a lot of small triangles near the poles. In an attempt to reduce the number triangles at the poles, we've changed out mesh generation to produce more evenly sized triangles over the surface. The first triangulation method had the advantage that we could easily create a texture and drape it over the surface. It seems that in WPF it isn't possible to assign colors to vertices the way one would go about in OpenGL or Direct3D. With the second triangulation method it isn't apparent how to go about generating the texture and setting the texture coordinates, since the vertices aren't aligned to a grid anymore. Maybe it would be possible to create a linear texture containing a color for each vertex, but then how will that effect the coloring? Will it still render smoothly over the triangle surfaces as one would expect by applying per vertex coloring?

• How do I draw a graduated border on a polygon using GDI+ via C#/WinForms?

  - by AndyJ

  I have polygons of various shapes and sizes. They have a solid fill and currently a solid border. I would like to give the polygons a gradient on their edge to soften them. So far I've tried using a Pen with a LinearGradientBrush and whilst the effect it produces is very interesting it's most definitely not what I want ;) I've looked through the System.Drawing.Drawing2D namespace but there didn't seem to be any other classes that would be applicable for this purpose. I've had a search around and the articles that I can find are mostly about creating borders for rectangles, which are mush easier, or are irrelevant. So to summarize, does anyone have a way of drawing a gradient border in on a polygon using GDI+?

• Can a flex app (or a portion of a flex app) be made transparent to mouse clicks?

  - by Sam Jones

  I need to superimpose my Flex app above a plain HTML control on a web page, and be able to click through the Flex app to interact with the HTML control. Is there any way to do this? No permutation of mouseEnabled="false" or mouseChildren="false" seems to have the desired effect. Context: trying to integrate Google Earth API (JavaScript/HTML) with my flex app. I am leaving a portion of the flex app transparent and empty, and positioning the Google Earth widget just below that point in the z-index. Google Earth has to be behind flex, because there are some Flex controls periodically displayed in that space.

• Javascript: Remove checked status from disabled input (already checked)

  - by BoDiE2003

  Im trying to make this function to check an element and if its checked, or not, add or remove respective className. Also, if the element is disabled but is checked, it should un-check it and remove the className('yes') function init() { $(document.body).select('input').each(function(element) { if (!element.checked) { element.up().removeClassName('yes'); } else { element.up().addClassName('yes'); } if (element.checked && element.disabled) { element.checked = false; element.up().removeClassName('yes') } }); } Right now, the last part, is not working, no effect

• Can my app arrange a gdb breakpoint or watch?

  - by Larry Gritz

  Is there a way for my code to be instrumented to insert a break point or watch on a memory location that will be honored by gdb? (And presumably have no effect when gdb is not attached.) I know how to do such things as gdb commands within the gdb session, but for certain types of debugging it would be really handy to do it "programmatically", if you know what I mean -- for example, the bug only happens with a particular circumstance, not any of the first 11,024 times the crashing routine is called, or the first 43,028,503 times that memory location is modified, so setting a simple break point on the routine or watch point on the variable is not helpful -- it's all false positives. I'm concerned mostly about Linux, but curious about if similar solutions exist for OS X (or Windows, though obviously not with gdb).

• Getting a JFrame's actual current location

  - by Ian Fellows

  Hello community, I am trying to create a (child) JFrame which slides out from underneath one side of a second (parent) JFrame. The goal is to then have the child follow the parent around when it is moved, and respond to resizing events. This is somewhat related to this question. I have tried using a ComponentListener, but with this method the child only moves once the parent has come to a stop, whereas I would like the child to move as the parent is dragged around the screen. Another option I attempted was to start a new refresher thread that continually updated the child's location using getLocation() or getLocationOnScreen(), but the lag was the same as with ComponentListener. Is there a way to get the true actual location of a JFrame even in the midst of a drag? or if not, is there a way to get the effect of a sheet sliding out from underneath and following the Frame around?

• How can I make a Jeditable (jQuery) span activate editing on more than one event?

  - by JonathanHayward

  For the jQuery extension Jeditable, one of the parameters that can be specified is which DOM event will turn a div/span/... into a text input/textarea/... I would like to have more than one event serve as a trigger; that is, I would like either a click event or a contextmenu event to turn a span into an in-place edit area. Is there a graceful way to do this without forking Jeditable? --edit-- An example of code specifying the event is below. The parameter is optional, defaulting to a regular click. $(".edit_rightclick").editable("/ajax/save", { cancel: "Cancel", submit: "OK", tooltip: "Right click to edit.", event: "contextmenu", }); Calling twice, once for the regular click event with the event unspecified, and one for the contextmenu event (right-click if there are no switched mouse buttons or anything like that) does not seem to produce the intended effect of an element becoming editable in place on a click from either mouse button.

• jQuer image hover animate

• Does anyone have an updated version of the SQLite .NET assembly, ie. SQLite 3.6.23.1 + possibly .NET

  - by Lasse V. Karlsen

  I'm at my wits end with the best .NET assembly version of SQLite, the one found at http://sqlite.phxsoftware.com. The only maintainer doesn't seem to have the time to update the library and it generally takes months, if not more, for newer versions to surface. Luckily, he has published the source code, so I'm hoping that someone else has made his/her own copy of it, and made the changes, and would be willing to share a copy. I've seen comments on the forums for the library to this effect, but sadly even the forum software seems to be grinding to a halt these days as password reminder emails seems to be lost to the big void, so I can't ask the few there that has said they have done it. So I'm here, hopefully the big userbase of StackOverflow can help. What I'm looking for: Updated with the latest changes to SQLite, ie. SQLite version 3.6.23.1 Possibly built for .NET 4.0 (I can do that if I can get a copy of working source) Does anyone have, or know of anyone, that has done this?

• Django: Extending User Model - Inline User fields in UserProfile

  - by Jack Sparrow

  Is there a way to display User fields under a form that adds/edits a UserProfile model? I am extending default Django User model like this: class UserProfile(models.Model): user = models.OneToOneField(User, unique=True) about = models.TextField(blank=True) I know that it is possible to make a: class UserProfileInlineAdmin(admin.TabularInline): and then inline this in User ModelAdmin but I want to achieve the opposite effect, something like inverse inlining, displaying the fields of the model pointed by the OneToOne Relationship (User) in the page of the model defining the relationship (UserProfile). I don't care if it would be in the admin or in a custom view/template. I just need to know how to achieve this. I've been struggling with ModelForms and Formsets, I know the answer is somewhere there, but my little experience in Django doesn't allow me to come up with the solution yet. A little example would be really helpful!

• Assigning a previous fieldvalue to a field in the next record

  - by user2945849

  I am working on a loan amortization schedule using Access, I have created the following tables: tblMembers - autoMemberID|txtLN|txtFN|etc tblLoans - autoLoanID|numMemberID|etc tblSchedules -autoScheduleID|numLoanID|numPayment#|datDue|dblBegin|...|dblEnd tblPayments - autoPaymID|numLoanID|curAmtPaid|datPaidDate and forms: frmLoans - autoLoanID|etc sbfSchedules - numPaymID|datDue|dblBegin|...|dblEnd sbfPayments - dblAmount|datPaid I have been able to generate the schedule (using DAO recordset) clicking a btnRepaymentSchedule the challenge is when I click a btnAddPayment still on the sbfSchedules, I want the value of the dblEnd field to be the value of the next record dblBegin field! I have tried using dlookup(txtBeginBalance = Dlookup("EndBalance", _ "Schedules","[ScheduleID] = Form![Schedules]![ScheduleID]-1) but there is no effect but if I use txtBeginBalance = txtEndBalance the value of txtEndBalance is assigned to the value of txtBeginBalance of the same record (want next record). Secondly, how can I set focus to the next record if a contro(txtAmountPaid) is not null on clicking the btnAddPayment or assigning the value of a calculation when the control is 0 or null ? Thanks
