• HTML/Javascript: Is it possible to remember the filename from a fileupload field ONLY and then later

  - by Pieter Breed

  I have a HTML file upload field from which I'm reading the file name of the file that the user specifies. The actual contents of the file is never uploaded. At a later stage, is it possible to construct a link using this file name information so that if the user clicks on this link, the original file is launched into a new browser window? If not, what are the reason for disallowing this behaviour? The purpose of such a feature is to store links to documents that are available on a mapped local drive or a network share.

• jQuery .get()/.post() doesn't send an updated cookie

  - by Markus

  Hello, I'am doing something like this: function setCookie(name, value, expire) { var exdate = new Date(); exdate.setDate(exdate.getDate()+expire); document.cookie=name+ "=" +escape(value)+((expire==null) ? "" : ";expires="+exdate.toGMTString()); } // When I click a button // Update the cookie setCookie("test", "1"); function getContent() { // Get the data of our new URL $.get("index.php", loadContent); } function loadContent(data) { // alert the new title // the PHP script is changing title after what cookie-value you have alert($("title", data).text()) } First of all, when Iam alerting it is still the last showing up. So I guess it doesn't send the changed cookies at all.. And for some reason I don't see the request in my Live HTTP Headers window... But also, if i request the URL(without the ajax) it works just fine What am I doing wrong here? Regards Markus

• Is it a problem if i query again and again to SQL Server 2005 and 2000?

  - by learner

  Window app i am constructing is for very low end machines (Celeron with max 128 RAM). From the following two approaches which one is the best (I don't want that application becomes memory hog for low end machines):- Approach One:- Query the database Select GUID from Table1 where DateTime <= @givendate which is returning me more than 300 thousands records (but only one field i.e. GUID - 300 thousands GUIDs). Now running a loop to achieve next process of this software based on GUID. Second Approach:- Query the database Select Top 1 GUID from Table1 where DateTime <= @givendate with top 1 again and again until all 300 thousands records done. It will return me only one GUID at a time, and I can do my next step of operation. What do you suggest which approach will use the less Memory Resources?? (Speed / performance is not the issue here).

• Yahoo Astra flash component error BaseScrollPane not found

  - by Chris

  I'm trying to use the Astra library from Yahoo but I'm getting an error saying the base class BaseScrollPane is not found. It appears to be imported from fl.containers.BaseScrollPane, which leads me to believe it should be a part of the base flash 10 library and therefore should be available, but it appears to be missing. Is this part of a separate package from somewhere? Update: For what it's worth, I found the actual class files in the Configuration/Component Source folder on my hard drive, but adding that to the class path (as well as the Components directory) did no good. I ended up fixing the issue by dragging a scroll pane component to the stage from the Components window and then deleting it, but I'm not sure what exactly that action changed that made it work, and would like to know for future reference.

• FJSTransitionController setup and use in View Controller not main app delegate

  - by elliotrock

  I am trying to set up Corey Floyd's FJSTransitionController. My app uses a main view controller to manage the main view navigation. I also went through the source to fix it for ARC. Followed instructions and in my main delegate .h I have in the usual spots: FJTransitionController* mainTransitionController; @property (nonatomic,retain) FJTransitionController* mainTransitionController; delegate .m has the following @synthesize mainTransitionController And in the - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions mainTransitionController=[[FJTransitionController alloc] init]; // do I need to instantise? [self.window addSubview:mainTransitionController.view]; [mainTransitionController setViewControllerClass:[[mainViewController sendMissionsPanelViewController] class] forKey:@"missionView"]; The last line is complaining that there is no @interface for FJTransitionController? Any help please.

• How to draw to screen in c++ ?

  - by Kesarion

  How would I draw something on the screen ? not the console window but the entire screen, preferably with the console minimised. Also, would it show up on a printscreen ? What I want to do is create something like a layer on top of the screen that only me and my aplication are aware of yet still be able to use aplications as usual. Here's an example: Let's say I want 2 yellow squares 5 by 5 pixels in size appearing in the center of the screen on top of all the other applications, unclickable and invisible to a printscreen.

• Alternative way to notify the user of an error

  - by Lily

  I have a winform software that communicates with hardware through a protocol. Sometimes error in communication happens and i would like to notify the user. Errors could be for example: timeouts, crc errors, physical disconnection etc... I have a communication window in which i show these errors, but by default this is hidden. The user can open it though the menubar. Popups are annoying to the user (and to myself) so i would like a un-invasive way to notify the user that an error has occurred. Perhaps a info bubble like when XP tells you updates are ready for your computer? I know that NotifyIcon can help put things in the system tray, which i do not wish to have. I'd rather keep it within my MDI. I'm open to other creative ideas as well.

• How do I change the Unit:Characters in Matlab?

  - by Jonas

  For portability, I set the units of my GUIs to 'characters'. Now I have a user who wants to use Matlab on his netbook, and the GUI window is larger than the screen (and thus cropped at the top). I think I could try and write something in the openingFcn of the GUI that measures screen size and then adjusts the GUI accordingly, but I'd rather avoid that, because I then need to deal with text that is bigger than the text boxes, etc. What I'd rather like to do is somehow adjust the unit 'character' on his Matlab installation. None of the font sizes in the preferences seem to have an effect on unit:character, though. Does anyone know whether there's a setting for that, which can be changed from within Matlab (I don't mind if it's something that is reset at every reboot, since I can just put it into the startup script)?

• Mac OS X: getting names of changed/written files

  - by Patrick

  I remember having a command line tool on an older Mac OS X version (Tiger?) that told me the name of every file that was written to (or read) by any process on the system. It used fseventd (? or something like that). Is there something like that for the newest Mac OS X (10.6)? It should be run in a terminal window and then I can use the system as normal. Let's say I type cat /etc/passwd, the output of that program would be similar to /bin/cat /etc/passwd I can't use lsof because I can't get the timing right. Is this clear or do you need more information?

• Compare text with innerHTML IE7 problem

  - by Beefo

  I can't find a work around for the innerHTML bug in IE7. I need to look at the contents of dynamicly generated HTML and change it if the text is "-1". I'm using the prototype js gallery but couldn't find a fix. Any ideas? JS: <script language="javascript" type="text/javascript"> Event.observe(window, 'load', function () { var num = 1; var allAccountInfoItems = $A('accountInfoItem'); var numofElements = (allAccountInfoItems.length); for (var x = 0; x < numofElements; x++ ) { var oldHTML = $('accountInfo').innerHTML; var newHTML = "Unlimited"; if (oldHTML == "-1") { $('accountInfo').update(newHTML); } var oldId = $('accountInfo').id; var numPlus = num++; $('accountInfo').id = oldId + numPlus; } }); </script>

• AutoComplete textbox and "Hide Pointer While Typing" in windows

  - by Joe

  How can the "Hide Pointer While Typing" option be disabled by application? I'm having an issue with the cursor hiding and not getting it back without pressing escape or losing window focus. The application has been written in C# and uses WPF. A technology specific answer is not required because it'll likely be possible using any technology. Here's the scenario: A user can type in a TextBox and an AutoComplete list shows up below the box. Once the user starts typing though, he/she can no longer select an item from the drop down because there is no mouse cursor. I noticed that Firefox does not have this behavior. For example, while typing in a URL in the address bar the mouse cursor never disappears. There are other places I've seen this behavior so I know it must be possible. Any help is greatly appreciated!

• OpenGL game written in C with a Cocoa front-end I want to port to Windows

  - by Philip

  Hello, I'm wondering if someone could offer me some tips on how to go about this. I have a MacOS X OpenGL game that is written in very portable C with the exception of the non-game-play GUI. So in Cocoa I set up the window and OpenGL context, manage preferences, registration, listen for keystrokes etc. But all of the drawing and processing of input is handled in nice portable C. So I want to port to Windows. I figured the obvious way to go about was to use the Win32 api. Then I started to read a primer on Win32 and began to wonder if maybe life isn't too short. Can I do this in C# (without converting the backend to C#)? I'd rather devote the time to learning C# than Win32. Any suggestions would be most welcome. I really don't know a lick about Windows. The last version I regularly used was 3.1...

• Can we execute methods / code in XCcode just like in Visual Studio?

  - by balexandre

  Visual Studio is one of the best developer IDE of all times, and now was improved with multithreading debugging and much more. My question is regarding Xcode and the ability to execute code just like we do in Visual Studio. Let's assume an object in a view and I want to run, let's say: [pickerView setHidden:YES]; in a breakpoint just to see if in that break point I could actually hide the object. I can't find any place for this in the XCode Debugger Am I missing something or I can't execute code that is not in the files already? like in Visual Studio Watch List or Immediate Window

• Is there a way to hide a row or column in excel without using VBA?

  - by AJ

  I know of several approaches using a macro (VBA) to show/hide columns and rows in Excel, but I cannot figure out or find a way to do this using either a formula or conditional formatting. Of particular interest is Excel 2007 - but I'd be curious to know if someone has managed to do it in any version of Excel. For those who want background, I have a spread of data with dates across the top and labels down the first column. I would like to specify a date window (on another sheet) as two cells with drop down dates (months) which would then show/hide the appropriate columns on the data sheet.

• Is there a transformation matrix that can scale the x and/or y axis logarithmically?

  - by Dave M

  I'm using .net WPF geometry classes to graph waveforms. I've been using the matrix transformations to convert from the screen coordinate space to my coordinate space for the waveform. Everything works great and it's really simple to keep track of my window and scaling, etc. I can even use the inverse transform to calculate the mouse position in terms of the coordinate space. I use the built in Scaling and Translation classes and then a custom matrix to do the y-axis flipping (there's not a prefab matrix for flipping). I want to be able to graph these waveforms on a log scale as well (either x axis or y axis or both), but I'm not sure if this is even possible to do with a matrix transformation. Does anyone know if this is possible, and if it is, what is the matrix?

• Rebind a unbind click

  - by Antonio Ortiz

  I am using this library that allows you to create a more elegant alert box (you can even use images!); I used it with a click function and it works! A nice container opens with a close button, GREAT! I noticed if you happen to click more than once on the link you assigned, it keeps firing. So multiple images begin to propagate. I used the unbind method, but it cancels the link permanently (until refresh etc.). I was surprised to see the library doesn't compensate for this little problem, so I am wondering if you could rebind the click when you close the image window so it starts from the beginning. $(".shopFrag").click(function(){ Messi.img("_images/wishlist.jpg"); $(".shopFrag").unbind('click'); });

• IE issues with drag/drop (script.aculo.us)

  - by deb

  I have a page with a left and a right div. Inside each of these there are several divs. I can drag&drop them inside the left/right divs or move from one to the other So the page is something like ........ ........ ........ ........ I am using scriptaculous and prototype for the drag&drop If I drag in Firefox things work fine. In IE6-IE8 however I have 2 problems: 1) When I drag from left to right or the other way around, the inner divs do not keep their relative distances: the div I moved now overlaps with the div on the opposite side (if I do a reload of the page the divs are set correctly again) 2) If I shrink the window width below a certain width the divs either on the left or the right droppable disappear. Any ideas? deb

• scrollTop with jQuery

  - by Narcís

  I want a foot to be at the bottom of the page. But when the user makes the window smaller, the two divs come together, it would be better that begins the scroll and hides the foot. I don't know if I explain? I have the code life here: http://jsfiddle.net/mdAsn/ $(function(){ $(document).scroll(function(){ var topDistance = $('#foot').scrollTop(); if(topDistance >= 420){ $('#foot').css({position: 'absolute',bottom:'10px'}); } else{ $('#foot').css({position: 'absolute',top:'410px'}); } }); })

• Facebook "->api" permissions

  - by Matthieu Marcé

  I have trouble using Facebook auth on my website... I'm using the PHP Sdk and I don't understand why I can use some functions like "getLoginUrl"/"getLoginStatusUrl"/"getUser" (with right answers : the facebook session is started, i get the user's facebook ID) and when I want to use something like $me = $facebook->api("/me/permissions"); or just $me = $facebook->api("/me"); there's always an exception and nothing works ... I guess it has something to do with permissions or token maybe, but I don't know what. When the user sign up on my website, I ask permissions I need with this scope : "email,user_about_me,user_location,read_friendlists,publish_stream" A clue that the permissions seem to be ok is that when the exception occures, I ask the user to sign in again (facebook connect) and no window appears as if everything's ok, but still, the page is reloaded and the exception appears again and again... Please help, Thank you !

• Which display manager for a non interactive Python app and mplayer?

  - by Matt

  I am developing an application that will run on Linux to run fullscreen all the time (no menus or trays or anything will be visible). The application is going to be developed in Python, not that that matters as far as the display manager, but what I am having a hard time with is choosing a display manager. I need something with the smallest possible footprint, that will let me run a graphical Python app and have an mplayer window at the same time, at widescreen resolutions (widescreen, 16:10,16:9, etc). Other than that, it doesn't need a lot of features, but the end footprint size is the most important thing I'll be looking at. What display manager would you recommend?

• Why is this javascript function so slow on Firefox?

  - by macrael

  This function was adapted from the website: http://eriwen.com/javascript/measure-ems-for-layout/ function getEmSize(el) { var tempDiv = document.createElement("div"); tempDiv.style.height = "1em"; el.appendChild(tempDiv); var emSize = tempDiv.offsetHeight; el.removeChild(tempDiv); return emSize; } I am running this function as part of another function on window.resize, and it is causing performance problems on Firefox 3.6 that do not exist on current Safari or Chrome. Firefox's profiler says I'm spending the most time in this function and I'm curious as to why that is. Is there a way to get the em size in javascript without doing all this work? I would like to recalculate the size on resize incase the user has changed it.

• html - how do I make a page load in a new tab in IE8?

  - by erynion

  My website works in Firefox - pages on the site load in the current tab, and links off site load a new tab. IE8 won't behave: target="_blank" opens a whole new window; the other options, _self _top _parent, all open the page in the current tab. I have Firefox set to "Open new windows in a new tab." The links to pages on my site all have target="_self" and Firefox keeps these in the current tab. On the external links I don't have a target set (I added _blank to see if it fixed IE8, and doing that didn't affect Firefox). I can't find an equivalent setting in IE8. Tools-Internet Options-General-Tabs/Settings has an enable tabs box, and a sub-option to automatically switch to newly opened tabs. Is there some html that will work? An IE8 setting I'm missing? Any help appreciated.
