• Word forms with too many ActiveX checkboxes load slowly.

  - by Luke

  Hi there, my company's software product has a feature that allows users to generate forms from Word templates. The program auto fills some fields from the SQL database and the user can fill in other data that they desire. So we have a .dotx template that holds the design of the form, and then the user gets the .docx file to fill out when they call it from our program. The problem we're having is that some of our users have been finding that the forms take an exceptionally long time to open up and then, once open, are so slow to respond (scroll around, etc) that they're unusable. So in my investigations so far, I've found out that the problem systems are one with lower powered CPUs (unfortunately it happens for systems above our system requirements) and the Word forms that cause the problems are ones with large amount of ActiveX style checkboxes on them. I verified that reducing the ActiveX checkboxes fixes the form loading problems. So I have the following questions about solutions (we're using Word 2007): 1) Is there any way to configure Word, or some other settings, so that there won't be such a strain opening a Word form with lots of ActiveX checkboxes? Any way of speeding up Word's opening? 2) Using Legacy style checkboxes instead of the ActiveX ones makes the forms load fine, but it looks like the user has to double-click the checkbox and change Default Value-Checked. Is there a way to configure it so that they can simply click on the checkbox to tick it? "Legacy Forms" checkbox as a name kind of worries me (Legacy…), does that mean a future version of word at some point wouldn't load the checkboxes because they're "legacy"? 3) Yes, it became clear to me after a little bit of research into solutions that Word is not the tool for the job for forms like I'm describing. InfoPath seems to be exactly what we should have been using all along but unfortunately I wasn't involved in the decision making or development of these forms, just tasked with coming up with a solution. I'd appreciate answers to any of these, or if anyone has any other ideas for solutions to this problem. Thanks

• Android SDK not recognizing debug-able device.

  - by kal.zekdor

  I'm new to Android development, and am attempting to run a test application on my actual device. I followed the instructions at http://developer.android.com/guide/developing/device.html (and related links), but the Android Debug Bridge (adb) doesn't recognize my connected device. Some quick background info, I'm running WinXP, developing with Eclipse, with a Motorola Droid running Android 2.1 as my physical device. An overview of the steps I've taken: Installed the Android SDK, downloading all necessary packages. Enabled USB Debugging on my device. Connected Device via USB, installing the driver from the SDK folder. I'll stop here (though I continued to setup my application to be debug-able in Eclipse), because I at this point I noticed a problem. Running "sdk\tools\adb devices" at this point (at least, by my understanding), should list my device as connected. However, running this yields only: List of devices attached My device recognizes that it's connected to a computer in debug mode, and my computer recognizes the device. However, I can't seem to get the sdk to recognize it. I'll leave out the steps I used to setup Eclipse for debugging on a device, as it doesn't seem relevant to the problem. I'll include them if requested. If anyone has any ideas, I'd greatly appreciate some assistance. Thanks in advance for your time.

• how would I call/use Subsonic from within a WinForms app being deployed over clickonce (with Sqlite

  - by Greg

  Hi, Background - I need a framework/approach to managed database updates for a .NET Winforms app being deployed on users PC's via clickonce deploy. The app uses a sqlite database. Q1. What mechanism does Subsonic use to run such migrations on the local PC? e.g. would it be MSBuild Q2. If it does need a tool like how can my application robustly kick off MsBuild? i.e. how can it be sure what path it is installed, what if it is not installed, should I be including the MSBuild.exe in the clickonce package so that I know it is there for sure myself? Q3. Any other suggestions on how to use Subsonic in this specific use case? Q4. Any comments on whether MigratorDotNet would be a better fit? (if someone has had experience with both) Q5. Could I use subsonic's bare migration framework and just have a set of SQL files to do the upgrade/downgrade? i.e. just use the framework to check database version and which scripts to run etc?

• jQuery noobie can't make a checked checkbox show an alert.

  - by Kyle Sevenoaks

  I found this answer before, to fire an alert if the button is pressed but the checkbox isn't checked. Why won't this work? <input value="1" type="checkbox" name="salgsvilkar" ID="checkbox2" style="float:left;" onclick="document.getElementById('scrollwrap').style.cssText='border-color:#85c222; background-color:#E5F7C7;';" /><label for="checkbox2" class="akslabel">Salgs og leveringsvilkår er lest og akseptert</label> </span> {literal} <script type="text/javascript"> $(function() { //checkbox $("#checkbox2").click(function(){ //if this... //alert("this")... if($("#checkbox2").is(':checked')) { alert("im checked"); } }); //button $("#fullfor_btn").click(function(e){ if(!$("#checkbox2").is(':checked')) { alert("you did not check the agree to terms..."); e.preventDefault(); } }); } </script> {/literal} This on another .tpl: <label></label> <button type="submit" class="submit" name="{$method}" id="fullfor_btn" title="Fullfør bestillingen nå" value="">&nbsp;</button> What could be going wrong? The jQuery doesn't fire anything at all.

• Code smells galore. Can this be a good company?

  - by Paperflyer

  I am currently doing some contract work for a company. Now they want to hire me for real. I have been reading on SO about code smells lately. The thing is, I have worked with some of their code and it smells. Badly. They use incredibly old versions of MSVC (2003), they do not seem to use version control systems, most code is completely undocumented, variable names with more than three letters are a rarity, there is commented out code all over the place, some methods take huge amounts of arguments, UI design is seemingly done by blind people... Yet they seem to be quite successful with what they do and their actual algorithms seem to be pretty sound and rather sophisticated. Since they mostly do DSP stuff, I am willing to ignore the UI side of things, but really these code smells are worrying. What would you think of a company that doesn't seem to value readable code? The people are nice enough and payment would be good. How much would you value code smells in this context? You see, this is my first job and SO got me worried, so I turn to you for suggestions ;-)

• Scientific Algorithms that can produce imagery, pseudocode perhaps?

  - by Ross

  Hello, I have a client who are based in the field of mathematics. We are developing, amongst other things, a website. I like to create a mock-up of a drawing tool that an produce some imagery in the background based on some scientific algorithms. The intention being that the may client, later, may create there own. (They use emacs for everything, great client.) I'm look for an answer of where or what to go looking for. Not code specific, pseudocode even, as we can adapt and have not yet settled on a platform. I'm afraid my mathematic stops at the power of two and some trigonometry. Appreciated if they're are any mathematics related students/academics how could enlighten me? What to search for will be accepted? Edit: To summarise/clarify, I want to draw pretty pictures (the design perspective). I want them to have some context (i.e. not just for the sake of pretty images but have some explanation available). In essence I would to create a rendering engine which we can draw the images and we set the style parameters: line, colour, etc... But to pursue this option I want to experiment myself. Thanks Ross

• Ajax: strange behaviour while checking a textfield

  - by ilnur777

  I have a registration form with checking the available name for username field through ajax. Inputing a username into username field and pushing the "Check!" button, the script sends value to php script. Then php script replaces the username field with the username field + style like this: <input type="text" name="login" value="'.$_GET["user"].'" style="width:205; height:22; border-width:1; border-color:red; border-style:solid; background-color:rgb(255,232,230);"> So when replacing the username field in the form with its equivalent from php script and then submitting a form, it is then get to script on the page that checks whether the username field is empty or not. And it returns an error that it is empty, though after checking through ajax the username field it has value. I don't understand why it gets to empty field checking script, having the same field name and having value?

• Android: Speeding up display of (html-formatted) text

  - by prepbgg

  My app uses a StringBuilder to assemble paragraphs of text which are then displayed in a TextView within a ScrollView. The displaytext.xml layout file is: <?xml version="1.0" encoding="utf-8"?> <LinearLayout android:id="@+id/LinearLayout01" android:layout_width="fill_parent" android:layout_height="fill_parent" android:background="#FFFFFF" xmlns:android="http://schemas.android.com/apk/res/android"> <ScrollView android:id="@+id/ScrollView01" android:layout_width="fill_parent" android:layout_height="wrap_content" > <TextView xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/display_text" android:layout_width="fill_parent" android:layout_height="wrap_content" android:textColor="#000000" > </TextView> </ScrollView> </LinearLayout> and the code that displays the StringBuilder object sbText is setContentView(R.layout.displaytext); TextView tv = (TextView)findViewById(R.id.display_text); tv.setText(Html.fromHtml(sbText.toString())); This works OK, except that it gets very slow as the amount of text grows. For example, to display 50 paragraphs totalling about 50KB of text takes over 5 seconds just to execute those three lines of code. Can anyone suggest how I can speed this up, please?

• why do we need advanced knowledge of mathematics & physics for programming?

  - by Sumeet

  Guys, I have been very good in mathematics and physics in my schools and colleges. Right now I am a programmer. Even in the colleges I have to engrossed my self into computers and programming things all the time. As I used to like it very much. But I have always felt the lack of advanced mathematics and physics in all the work I have done (Programs). Programming never asked me any advanced mathematics and physics knowledge in what I was very good. It always ask u some optimized loops, and different programming technologies which has never been covered in advanced mathematics and physics. Even at the time of selection in big College , such a kind of advanced knowledge is required. Time by time I got out of touch of all that facts and concepts (advanced mathematics and physics). And now after, 5 years in job I found it hard to resolve Differentiations and integrations from Trigonometry. Which sometimes make me feel like I have wasted time in those concepts because they are never used. (At that time I knew that I am going to be a programmer) If one need to be a programmer why do all this advanced knowledge is required. One can go with elementry knowledge a bit more. You never got to think like scientists and R&D person in your Schols and colleges for being a programmer? Just think and let me know your thoughts. I must be wrong somewhere in what I think , but not able to figure that out..? Regards Sumeet

• How to display a busy message over a wpf screen

  - by dave

  Hey, I have a WPF application based on Prism4. When performing slow operations, I want to show a busy screen. I will have a large number of screens, so I'm trying to build a single solution into the framework rather than adding the busy indicator to each screen. These long running operations run in a background thread. This allows the UI to be updated (good) but does not stop the user from using the UI (bad). What I'd like to do is overlay a control with a spinning dial sort of thing and have that control cover the entire screen (the old HTML trick with DIVs). When the app is busy, the control would display thus block any further interaction as well as showing the spinny thing. To set this up, I thought I could just have my app screen in a canvas along with the spinny thing (with a greater ZIndex) then just make the spinny thing visible as required. This, however, is getting hard. Canvases do not seem well set up for this and I think I might be barking up the wrong tree. I would appreciate any help. Thanks.

• Reorganizing development environment for single developer/small shop

  - by Matthew

  I have been developing for my company for approximately three years. We serve up a web portal using Microsoft .NET and MS SQL Server on DotNetNuke. I am going to leave my job full time at the end of April. I am leaving on good terms, and I really care about this company and the state of the web project. Because I haven't worked in a team environment in a long time, I have probably lost touch with what 'real' setups look like. When I leave, I predict the company will either find another developer to take over, or at least have developers work on a contractual basis. Because I have not worked with other developers, I am very concerned with leaving the company (and the developer they hire) with a jumbled mess. I'd like to believe I am a good developer and everything makes sense, but I have no way to tell. My question, is how do I set up the development environment, so the company and the next developer will have little trouble getting started? What would you as a developer like in place before working on a project you've never worked on? Here's some relevant information: There is a development server onsite and a production server offsite in a data center . There is a server where backups and source code (Sourcegear Vault) are stored. There is no formal documentation but there are comments in the code. The company budget is tight so free suggestions will help the best. I will be around after the end of April on a consulting basis so I can ask simple questions but I will not be available full time to train someone

• Faster quadrature decoder loops with Python code

  - by Kelei

  I'm working with a BeagleBone Black and using Adafruit's IO Python library. Wrote a simple quadrature decoding function and it works perfectly fine when the motor runs at about 1800 RPM. But when the motor runs at higher speeds, the code starts missing some of the interrupts and the encoder counts start to accumulate errors. Do you guys have any suggestions as to how I can make the code more efficient or if there are functions which can cycle the interrupts at a higher frequency. Thanks, Kel Here's the code: # Define encoder count function def encodercount(term): global counts global Encoder_A global Encoder_A_old global Encoder_B global Encoder_B_old global error Encoder_A = GPIO.input('P8_7') # stores the value of the encoders at time of interrupt Encoder_B = GPIO.input('P8_8') if Encoder_A == Encoder_A_old and Encoder_B == Encoder_B_old: # this will be an error error += 1 print 'Error count is %s' %error elif (Encoder_A == 1 and Encoder_B_old == 0) or (Encoder_A == 0 and Encoder_B_old == 1): # this will be clockwise rotation counts += 1 print 'Encoder count is %s' %counts print 'AB is %s %s' % (Encoder_A, Encoder_B) elif (Encoder_A == 1 and Encoder_B_old == 1) or (Encoder_A == 0 and Encoder_B_old == 0): # this will be counter-clockwise rotation counts -= 1 print 'Encoder count is %s' %counts print 'AB is %s %s' % (Encoder_A, Encoder_B) else: #this will be an error as well error += 1 print 'Error count is %s' %error Encoder_A_old = Encoder_A # store the current encoder values as old values to be used as comparison in the next loop Encoder_B_old = Encoder_B # Initialize the interrupts - these trigger on the both the rising and falling GPIO.add_event_detect('P8_7', GPIO.BOTH, callback = encodercount) # Encoder A GPIO.add_event_detect('P8_8', GPIO.BOTH, callback = encodercount) # Encoder B # This is the part of the code which runs normally in the background while True: time.sleep(1)

• WCF Async callback setup for polled device

  - by Mark Pim

  I have a WCF service setup to control a USB fingerprint reader from our .Net applications. This works fine and I can ask it to enroll users and so on. The reader allows identification (it tells you that a particular user has presented their finger, as opposed to asking it to verify that a particular user's finger is present), but the device must be constantly polled while in identification mode for its status - when a user is detected the status changes. What I want is for an interested application to notify the service that it wants to know when a user is identified, and provide a callback that gets triggered when this happens. The WCF service will return immediately and spawn a thread in the background to continuously poll the device. This polling could go on for hours at a time if no one tries to log in. What's the best way to acheive this? My service contract is currently defined as follows: [ServiceContract (CallbackContract=typeof(IBiometricCallback))] public interface IBiometricWcfService { ... [OperationContract (IsOneWay = true)] void BeginIdentification(); ... } public interface IBiometricCallback { ... [OperationContract(IsOneWay = true)] void IdentificationFinished(int aUserId, string aMessage, bool aSuccess); ... } In my BeginIdentification() method can I easily spawn a worker thread to poll the device, or is it easier to make the WCF service asynchronous?

• How do I update a webpage with the progress of a server-side task?

  - by Jim B

  Hi everyone, I'm working on a web project that takes the results from a survey type application, and runs them through a bunch of calculations to come up with some recommended suggestions for the user. Now, this calculation might take a minute or so, so I'd like to be able to give the user some update on it's progress. Obviously, the quick and dirty solution would be to put up a message along the lines of "Please wait while we calculate your recommendations" with a spinning gear type graphic. (or whatever, you get the point..). Once the task completes, I'd redirect to the results page. However, I'd like to do something a little more flashy. Maybe something along the lines of a progress bar, and even prompt the user with what's going on in the background. For example, give them a progress bar, with some text that says "Now processing suggestion 3 of 15; Multi-Vitamin" Any suggestions on how I could set this up? One way I'm thinking of doing it is to write the progress of the calculation method to the HttpContext, and slap up an update panel and timer that would show/refresh this info. I've also checked out maybe building a web service/method, and then poll that at some interval. Has anybody done something similar to this before? What worked for you? Thanks again! ~Jim

• Webkit browsers rendering CSS different than Mozilla Firefox...Why??

  - by JAG2007

  I'm styling a form that was already marked up (made some markup changes), and I normally work in Firefox to style so I can use firebug and the web developer toolbar. On this project, I noticed that my styles are displaying quite differently for one particular area (several elements) in webkit based browsers Chrome and Safari, than in Firefox (we won't even get into Internet Explorer, although it is siding with the Firefox display). I can't figure out though why the styles are displaying so differently. Normally there is some rule that I'm neglecting that Firefox just takes for granted, and the others need it specified. But here I'm not getting why it's displaying this way. In particular I'm referring to the bottom area of the form where users can enter their contact info, then submit the form. I'll attach screen shots for reference as to the discrepancy. Here's the URL so feel free to check it out on your own. Although be advised that this is a production page (already released) so if you try out the form, you WILL BE added to CURE's contact database. http://www.helpcurenow.org/survey2010 Here's the screen shots: Firefox (the way I intend it to look) Chrome, and then Safari - strange change to submit button As a bonus, if anybody wants to help me with figuring out why on earth IE7 wants to not show the background behind the questions only, and how to fix that I would be much obliged! Thanks very much.

• Issues with simulating cell selection in Excel using PostMessage

  - by DD

  Hi all, So far I've tried drag/drop motion in many applications including Visualization software (moving time slider left/right), Photoshop-Paint (drawing) etc. I need some more testing before I make sure that my system works and it failed in Excel. I'm using the code below to send the input: m.x = 215; m.y = 200 + 36 + 9 * ( currentTime - 1 ); childH = findChild( w->getHandle(), m ); PostMessage( childH, WM_MOUSEMOVE, 0, MAKELPARAM( m.x, m.y ) ); PostMessage( childH, WM_LBUTTONDOWN, MK_LBUTTON, MAKELPARAM( m.x, m.y ) ); m.x = 215; m.y = 200 + 36 + 9 * ( currentTime ); childH = findChild( w->getHandle(), m ); PostMessage( childH, WM_MOUSEMOVE, MK_LBUTTON, MAKELPARAM( m.x, m.y ) ); PostMessage( childH, WM_LBUTTONUP, 0, MAKELPARAM( m.x, m.y ) ); I can click anywhere in Excel and select the cell, or activate buttons/menus anything. I can even drag a plot around (with the code above) but it doesn't work for clicking and dragging the mouse to select multiple cells. It just doesn't do anything. I can't use SendInput because the window doesn't have the focus and is in background. Thanks!

• Custom UITableView headerView disappears after memory warning

  - by psychotik

  I have a UITableViewController. I create a custom headerView for it's tableView in the loadView method like so: (void)loadView { [super loadView]; UIView* containerView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, width, height * 2 )]; containerView.tag = 'cont'; containerView.autoresizingMask = UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleRightMargin | UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleTopMargin; UIButton* button = [UIButton buttonWithType:UIButtonTypeCustom]; button.frame = CGRectMake(padding, height, width, height); ... //configure UIButton and events UIImageView* imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"image.png"] highlightedImage:[UIImage imageNamed:@"highlight.png"]]; imageView.frame = CGRectMake(0, 0, width, height ); ... //configure UIImageView [containerView addSubview:button]; [containerView addSubview:imageView]; self.tableView.tableHeaderView = containerView; [imageView release]; [containerView release]; } None of the other methods (viewDidLoad/Unload, etc) are overloaded. This controller is hosted in a tab. When I switch to another tab and simulate a memory warning, and then come back to this tab, my UITableView is missing my custon header. All the rows/section are visible as I would expect. Putting a BP in the loadView code above, I see it being invoked when I switch back to the tab after the memory warning, and yet I can't actually see the header. Any ideas about what I'm missing here? EDIT: This happens on the device and the simulator. On the device, I just let a memory warning occur by opening a bunch of different apps while mine is in the background.

• Is it possible to spoof or reuse VIEWSTATE or detect if it is protected from modification?

  - by Peter Jaric

  Question ASP and ASP.NET web applications use a value called VIEWSTATE in forms. From what I understand, this is used to persist some kind of state on the client between requests to the web server. I have never worked with ASP or ASP.NET and need some help with two questions (and some sub-questions): 1) Is it possible to programmatically spoof/construct a VIEWSTATE for a form? Clarification: can a program look at a form and from that construct the contents of the base64-encoded VIEWSTATE value? 1 a) Or can it always just be left out? 1 b) Can an old VIEWSTATE for a particular form be reused in a later invocation of the same form, or would it just be luck if that worked? 2) I gather from http://msdn.microsoft.com/en-us/library/ms972976.aspx#viewstate_topic12 that it is possible to turn on security so that the VIEWSTATE becomes secure from spoofing. Is it possible for a program to detect that a VIEWSTATE is safeguarded in such a way? 2 a) Is there a one-to-one mapping between the occurrence of EVENTVALIDATION values and secure VIEWSTATEs? Regarding 1) and 2), if yes, can I have a hint about how I would do that? For 2) I am thinking I could base64-decode the value and search for a string that always is found in unencrypted VIEWSTATEs. "First:"? Something else? Background I have made a small tool for detecting and exploiting so called CSRF vulnerabilities. I use it to quickly make proof of concepts of such vulnerabilities that I send to the affected site owners. Quite often I encounter these forms with a VIEWSTATE, and these I don't know if they are secure or not. Edit 1: Clarified question 1 somewhat. Edit 2: Added text in italics.

• IE10 - Progress bar animation issue

  - by user3723885

  I'm trying to incorporate some animated progress bars but I'm having trouble getting them to animate in IE10. I believe the problem is due to the keyframes being inside the media query but have not been able to get it working. Thanks for your help. HTML: <td><div style="width:150px;height:15px;border:1px solid black"> <div class="meter"> <span style="width:85%;"><span class="progress"></span></span> </div> </div></td></tr> CSS: .progress { background-color: #325C74; -webkit-animation: progressBar 3s ease-in-out; -webkit-animation-fill-mode:both; -moz-animation: progressBar 3s ease-in-out; -moz-animation-fill-mode:both; } @-webkit-keyframes progressBar { 0% { width: 0; } 100% { width: 100%; } } @-moz-keyframes progressBar { 0% { width: 0; } 100% { width: 100%; } }

• Convert a Dynamic[] construct to a numerical list

  - by Leo Alekseyev

  I have been trying to put together something that allows me to extract points from a ListPlot in order to use them in further computations. My current approach is to select points with a Locator[]. This works fine for displaying points, but I cannot figure out how to extract numerical values from a construct with head Dynamic[]. Below is a self-contained example. By dragging the gray locator, you should be able to select points (indicated by the pink locator and stored in q, a list of two elements). This is the second line below the plot. Now I would like to pass q[[2]] to a function, or perhaps simply display it. However, Mathematica treats q as a single entity with head Dynamic, and thus taking the second part is impossible (hence the error message). Can anyone shed light on how to convert q into a regular list? EuclideanDistanceMod[p1_List, p2_List, fac_: {1, 1}] /; Length[p1] == Length[p2] := Plus @@ (fac.MapThread[Abs[#1 - #2]^2 &, {p1, p2}]) // Sqrt; test1 = {{1.`, 6.340196001221532`}, {1.`, 13.78779876355869`}, {1.045`, 6.2634018978377295`}, {1.045`, 13.754947081416544`}, {1.09`, 6.178367702583522`}, {1.09`, 13.72055251752498`}, {1.135`, 1.8183153704413153`}, {1.135`, 6.082497198000075`}, {1.135`, 13.684582525399742`}, {1.18`, 1.6809452373465104`}, {1.18`, 5.971583107298081`}, {1.18`, 13.646996905469383`}, {1.225`, 1.9480537697339537`}, {1.225`, 5.838386922625636`}, {1.225`, 13.607746407088161`}, {1.27`, 2.1183174369679234`}, {1.27`, 5.669799095595362`}, {1.27`, 13.566771130126131`}, {1.315`, 2.2572975468163463`}, {1.315`, 5.444014254828522`}, {1.315`, 13.523998701347882`}, {1.36`, 2.380307009155079`}, {1.36`, 5.153024664297602`}, {1.36`, 13.479342200528283`}, {1.405`, 2.4941312539733285`}, {1.405`, 4.861423833512566`}, {1.405`, 13.432697814928654`}, {1.45`, 2.6028066447609426`}, {1.45`, 4.619367407525507`}, {1.45`, 13.383942212133244`}}; DynamicModule[{p = {1.2, 10}, q = {1.3, 11}}, q := Dynamic@ First@test1[[ Ordering[{#, EuclideanDistanceMod[p, #, {1, .1}]} & /@ test1, 1, #1[[2]] < #2[[2]] &]]]; Grid[{{Show[{ListPlot[test1, Frame -> True, ImageSize -> 300], Graphics@Locator[Dynamic[p]], Graphics@ Locator[q, Appearance -> {Small}, Background -> Pink]}]}, {Dynamic@p}, {q},{q[[2]]}}]]
