• ASP.net 2.0 Gridview with Expanding Panel Rows -- How to build Panel "on the fly"

  - by jlrolin

  I'm currently building a Gridview that has expandable rows. Each row contains a dynamically created Panel of Form elements. Right now, I have a javascript function that expands (or in my case, makes visible) the panel when an Image is clicked on the Gridview row. My question is... is there a more efficient way of doing this. Instead of pulling all my data to begin with and building each new row as I Databind, is there a way to simple create the row with the Panel full of textboxes and dropdownlists on the fly when the user clicks the Expand button?" I'd like to limit the server calls by doing it that way instead of how I'm currently doing it, looping through every row and creating a new panel with form elements and inserting that into a row that is hidden.

• zip multiple file on the fly and download it as a zip folder php

  - by mishxpie

  I understand that I can zip multiple file and download it as zip when the files are already exists on ther server. like this. My question is, I have a dropdown list that prompt user download different section of a big form on the fly so I have header below for download it individually. header("Content-type: text/plain"); header("Content-Disposition: attachment; filename=op_summary.lyx"); I need to add another function to download them all at ones. How can I implement it? Should I have download them in the server before zipping it and download to client? I will also need a checkbox fundtion that pick multiple files according whichever files that user select. Any suggestion will be helpful.

• Encrypt/Decrypt SQLite-database and use it "on the fly"

  - by Berschi

  Here's the thing: In my Qt4.6-Project, I use a SQLite-Database. This database shouldn't be unencrypted on my harddrive. So I want, that on every start of my program, the user gets asked to enter a password to decrypt the database. Of course the database never should appear "in clear" (not encrypted) on my harddrive. So is there any possibility to decrypt a SQLite-database "on the fly" and read and write data? What algorithm is here the best (maybe AES)? When it's not possible (or very slow), maybe it's better to encrypt every string in the database and decrypt the string when the password was right (so that a user could open the database, but has no clue what all the entrys could mean)?

• C# CF: file encryption/decryption on the fly

  - by nuttynibbles

  Hi, i've seen many article on encrypt/decrypt of file and typically a button is used to choose the file for encrypt and another button to decrypt the file. i've seen some application like truecrypt and probably others which does file encryption on-the-fly with transparent. this means that when a encrypted file is clicked to access, it will automatically decrypt and play/open the file. then when the file is closed, it will automatically encrypt again. some have said that the only way to detect file open is through file system filter. but is there other ways to do this in c# compact framework?

• llvm clang struct creating functions on the fly

  - by anon

  I'm using LLVM-clang on Linux. Suppose in foo.cpp I have: struct Foo { int x, y; }; How can I create a function "magic" such that: typedef (Foo) SomeFunc(Foo a, Foo b); SomeFunc func = magic("struct Foo { int x, y; };"); so that: func(SomeFunc a, SomeFunc b); // returns a.x + b.y; ? Note: So basically, "magic" needs to take a char*, have LLVM parse it to get how C++ lays out the struct, then create a function on the fly that returns a.x + b.y; Thanks!

• Exporting query results to a file on the fly

  - by ercan

  Hi all, I need to export the results of a query to a csv file in an FTP folder. Is it possible to achieve this within a stored procedure? If yes, comes yet another constraint: can I achieve this without sysadmin privileges, aka without using xp_cmdshell + BCP utility? If no to 2., does the caller have to have sysadmin privileges or would it suffice if the SP owner has sysadmin privileges? Here are some more details to the problem: The SP must export and transfer the file on the fly and raise error if something went wrong. The caller must get a response immediately, i.e. in case of no error, he can assume that the results are successfully transferred to the folder. Therefore, a DTS/SSIS job that runs every N minutes is not an option. I know the problem smells like I will have to do this at application level, but I would be more than happy if all those stuff could be done from T-SQL.

• Access 2007 - Forms created on the fly

  - by glinch

  Hi There, Hopefully I can find some words of advice from somebody. Is it possible to create forms 'on-the fly' so to speak in MS-Access 2007 I have a structure of tables: tblCustomer tblQuestAns A customer may answer the questionnaire answers many times as they relate to all products. I propose to hopefully have an initial input form that will ask how many products of which there could be more than 1 eg: TV, Video (say the user selects 2) On entering that data the next form should hopefully update itself to include the list of questions eg TV Q1, Q2 Q3 - Video (1) Q1, Q2 Q3 - Video (2) Q1, Q2 Q3 Is that possible? Any point in the right direction would be appreciated. Thanks Noel

• Create LINQ to entities OrderBy expression on the fly

  - by AyKarsi

  I'm trying to add the orderby expression on the fly. But when the query below is executed I get the following exception: System.NotSupportedException: Unable to create a constant value of type 'Closure type'. Only primitive types ('such as Int32, String, and Guid') are supported in this context. The strange thing is, I am query exactly those primitive types only. string sortBy = HttpContext.Current.Request.QueryString["sidx"]; ParameterExpression prm = Expression.Parameter(typeof(buskerPosting), "posting"); Expression orderByProperty = Expression.Property(prm, sortBy); // get the paged records IQueryable<PostingListItemDto> query = (from posting in be.buskerPosting where posting.buskerAccount.cmsMember.nodeId == m.Id orderby orderByProperty //orderby posting.Created select new PostingListItemDto { Set = posting }).Skip<PostingListItemDto>((page - 1) * pageSize).Take<PostingListItemDto>(pageSize); Hope somebody can shed some light on this!

• PHP image resize on the fly vs storing resized images

  - by Pablo

  I'm building a image sharing site and would like to know the pros and cons of resizing images on the fly with php and having the resized images stored. Which is faster? Which is more reliable? how big is the gap between the two methods in speed and performance? Please note that either way the images go through a PHP script for statistics like views or if hotlinking is allow etc... so is not like it will be a direct link for images if i opt to store the resize images. I'll appreciated your comments or any helpful links on the subject, Thanks.

• Modify input stream data on the fly

  - by Frizi

  I would like to implement a std::stream modifier/parser, that is doing data manipulation on the fly. Is it possible to create it in form of stream manipulator? For example, i want to strip all the line comments (from any // to the end of line) out of the stdin and pass it to stdout. string str; istream strippingCin = cin >> stripcomments; while(strippingCin.good()) { strippingCin >> str; cout << str; } There may be also a large file input instead of cin, so i don't want to load full stream data into memory at once. Is it possible without writing my own stream class? Maybe is there another route i should take instead?

• Main page content populated on the fly?

  - by jcovert

  Is there any reason to NOT have a webpage retrieve it's main content on the fly? For example, I have a page that has a header and a footer, and in the middle of this page is an empty div. When you click on one of the buttons in the header, an http GET is done behind the scenes and the .innerHTML() of the empty div is replaced with the result. I can't think of any reason why this might be a bad idea, but I can't seem to find any pages out there that do it? Please advise!

• Problem with thumbnails after newly added - PHP on-the-fly method

  - by Wayne

  Hey again... to those that may have read my previous question that got solved a couple minutes ago .< The on-the-fly php script works perfectly, but when I went to upload new images into a gallery which I made myself, the images are resized to 150 x 150 for what I wanted... however, when it comes to new images being added it is all black... As you can see the three black images that were uploaded to the folder and the directory added to the database. What is causing this? If I view the source, the code is fine... the while loop in the PHP generates an output like this: <div class="view-wrap" id="photo-10"> <div class="view-icon"> <div class="img-label"> <a href="#" id="10" class="delete"><img src="img/small-delete.png" /> Delete</a> </div> <a href="img/events/Paintballing/24251_1395408043148_1170626626_1204038_5382765_n.jpg"> <img src="image.php?dir=img/events/Paintballing/24251_1395408043148_1170626626_1204038_5382765_n.jpg" alt="" width="110" height="110" /> </a> </div> </div> An example of one block. If I view the source (in Firefox) and click on the image.php?dir=img/events/Paintballing/24251_1395408043148_1170626626_1204038_5382765_n.jpg by exmaple, I can see the thumbnail at it's 150 x 150 size but in the layout, it shows a black thumbnail... Does anyone know why this is happening?

• Modifying CSS class property values on the fly with JavaScript / jQuery

  - by JPN

  all. I've run into a unique situation that I have so far been unable to find a solution for: dynamically assigning a value to a CSS style. I know how to use jQuery to assign width, height, etc. to an element, but what I'm trying to do is actually change the value defined in the stylesheet so that the dynamically-created value can be assigned to multiple elements. What I'm building is a slideshow of images that occupy the full viewport, recalculating the image's width, height, and left properties on resize so that the image is always centered, favors width over height, except when the viewport is taller than it is wide (resizing does not reload the page, just fires a function to resize the image). I have successfully been able to get it to work on one image, and now I'm trying to determine the best way to assign those property values to all images in the slideshow without having to specify those three things individually for every image. Can the values of properties in a class be modified on the fly? I'm sure the answer is out there, I'm probably just not using the correct terminology in my searches. Hope I did a good job of describing the problem. TIA.

• power and modulo on the fly for big numbers

  - by user unknown

  I raise some basis b to the power p and take the modulo m of that. Let's assume b=55170 or 55172 and m=3043839241 (which happens to be the square of 55171). The linux-calculator bc gives the results (we need this for control): echo "p=5606;b=55171;m=b*b;((b-1)^p)%m;((b+1)^p)%m" | bc 2734550616 309288627 Now calculating 55170^5606 gives a somewhat large number, but since I have to do a modulooperation, I can circumvent the usage of BigInt, I thought, because of: (a*b) % c == ((a%c) * (b%c))%c i.e. (9*7) % 5 == ((9%5) * (7%5))%5 => 63 % 5 == (4 * 2) %5 => 3 == 8 % 5 ... and a^d = a^(b+c) = a^b * a^c, therefore I can divide b+c by 2, which gives, for even or odd ds d/2 and d-(d/2), so for 8^5 I can calculate 8^2 * 8^3. So my (defective) method, which always cut's off the divisor on the fly looks like that: def powMod (b: Long, pot: Int, mod: Long) : Long = { if (pot == 1) b % mod else { val pot2 = pot/2 val pm1 = powMod (b, pot, mod) val pm2 = powMod (b, pot-pot2, mod) (pm1 * pm2) % mod } } and feeded with some values, powMod (55170, 5606, 3043839241L) res2: Long = 1885539617 powMod (55172, 5606, 3043839241L) res4: Long = 309288627 As we can see, the second result is exactly the same as the one above, but the first one looks quiet different. I'm doing a lot of such calculations, and they seem to be accurate as long as they stay in the range of Int, but I can't see any error. Using a BigInt works as well, but is way too slow: def calc2 (n: Int, pri: Long) = { val p: BigInt = pri val p3 = p * p val p1 = (p-1).pow (n) % (p3) val p2 = (p+1).pow (n) % (p3) print ("p1: " + p1 + " p2: " + p2) } calc2 (5606, 55171) p1: 2734550616 p2: 309288627 (same result as with bc) Can somebody see the error in powMod?

• Reload a UITable on the fly when editing a UITextField inside one of the cells

  - by Saze

  I have a UITable containing some customs UITableCells. Those cells contain a few UILabels and a UITextField. The datasource of the table comes from a main controller's property. (This controller is also the delegate and the dataSource for the table). Here's a simplified screenshot of the UI: Now, I need to update "on the fly" the content of all the UILabels when the user edits one of the UITextFields. To do so, at the I am listening to the "Editing Changed" event at the UITextField level. This triggers the following action: - (IBAction) editChangeHandler: (id) sender { MyAppDelegate *delegate = [[UIApplication sharedApplication] delegate]; [[delegate.viewController.myDataSourceArray objectAtIndex:self.rowIndex] setANumber: [theTextField.text intValue]]; [delegate.viewController reloadRows]; } The reloadRows method in the viewController is as such: - (void) reloadRows { NSLog(@"called reloadRows"); //perform some calculations on the data source objects here... [theUITable reloadData]; } My problem here is that whenever the user changes the value in the field, the reloadRows method is successfully called, so is apparently the reloadData but it also causes the keyboard to be dismissed. So in the end, the user can only touch one key when editing the TextField before the keyboard is dismissed and the table reloaded. Does anybody knows a solution to this or have experienced the same issue?

• Concatenate & Minify JS on the fly OR at build time - ASP.NET MVC

  - by Charlino

  As an extension to this question here Linking JavaScript Libraries in User Controls I was after some examples of how people are concatinating & minifying javascript on the fly OR at build time. I would also like to see how it then works into your master pages. I don't mind page specific files being minified and linked inidividually as they currently are (see below) but all the js files on the main master page (I have about 5 or 6) I would like concatenated and minified. Bonus points for anyone who also incorporates CSS concatenation & minification! :-) Current master page with the common js files that I would like concatenated & minified: <%@ Master Language="C#" Inherits="System.Web.Mvc.ViewMasterPage" %> <head runat="server"> ... BLAH ... <asp:ContentPlaceHolder ID="AdditionalHead" runat="server" /> ... BLAH ... <%= Html.CSSBlock("/styles/site.css") %> <%= Html.CSSBlock("/styles/jquery-ui-1.7.1.css") %> <%= Html.CSSBlock("/styles/jquery.lightbox-0.5.css") %> <%= Html.CSSBlock("/styles/ie6.css", 6) %> <%= Html.CSSBlock("/styles/ie7.css", 7) %> <asp:ContentPlaceHolder ID="AdditionalCSS" runat="server" /> </head> <body> ... BLAH ... <%= Html.JSBlock("/scripts/jquery-1.3.2.js", "/scripts/jquery-1.3.2.min.js") %> <%= Html.JSBlock("/scripts/jquery-ui-1.7.1.js", "/scripts/jquery-ui-1.7.1.min.js") %> <%= Html.JSBlock("/scripts/jquery.validate.js", "/scripts/jquery.validate.min.js") %> <%= Html.JSBlock("/scripts/jquery.lightbox-0.5.js", "/scripts/jquery.lightbox-0.5.min.js") %> <%= Html.JSBlock("/scripts/global.js", "/scripts/global.min.js") %> <asp:ContentPlaceHolder ID="AdditionalJS" runat="server" /> </body> Used in a page like this (which I'm happy with): <asp:Content ID="signUpContent" ContentPlaceHolderID="AdditionalJS" runat="server"> <%= Html.JSBlock("/scripts/pages/account.signup.js", "/scripts/pages/account.signup.min.js") %> </asp:Content> EDIT: What I'm using now Since asking this question, Microsoft have released their own JS & CSS compression library called Microsoft AJAX Minifier, I'd definitely recommend checking it out. It includes MSBuild tasks which are the duck's nuts.

• Embedding a Bitmap in ASP.NET's WebResource

  - by Andreas Grech

  I am generating a System.Drawing.Bitmap on the fly in an ASP.NET Custom Web Server Control, and then I want to serve this bitmap as part of the WebResource, because I do not want to save it on the hosting computer. Is there a way to instruct ASP.NET to serve the generated System.Drawing.Bitmap as part of it's WebResource? (therefore making it an "Embedded Resource")

• sOperator as and generic classes

  - by abatishchev

  I'm writing .NET On-the-Fly compiler for CLR scripting and want execution method make generic acceptable: object Execute() { return type.InvokeMember(..); } T Execute<T>() { return Execute() as T; /* doesn't work: The type parameter 'T' cannot be used with the 'as' operator because it does not have a class type constraint nor a 'class' constraint */ // also neither typeof(T) not T.GetType(), so on are possible return (T) Execute(); // ok } But I think operator as will be very useful: if result type isn't T method will return null, instead of an exception! Is it possible to do?

• Converting .docx to pdf (or .doc to pdf, or .doc to odt, etc.) with libreoffice on a webserver on the fly using php

  - by robertphyatt

  Ok, so I needed to convert .docx files to .pdf files on the fly, but none of the free php libraries that were available let me do it on my server (a webservice was not good enough). Basically either I needed to pay for a library (and have it maybe suck) or just deal with the free ones that didn't convert the formatting well enough. Not good enough! I found that LibreOffice (OpenOffice's successor) allows command line conversion using the LibreOffice conversion engine (which DID preserve the formatting like I wanted and generally worked great). I loaded the latest version of Ubuntu (http://www.ubuntu.com/download/ubuntu/download) onto my Virtual Box (https://www.virtualbox.org/wiki/Downloads) on my computer and found that I was able to easily convert files using the commandline like this: libreoffice --headless -convert-to pdf fileToConvert.docx -outdir output/path/for/pdf I thought: sweet...but I don't have admin rights on my host's web server. I tried to use a "portable" version of LibreOffice that I obtained from http://portablelinuxapps.org/ but I was unable to get it to work on my host's webserver, because my host's webserver didn't have all the dependencies (Dependency Hell! http://en.wikipedia.org/wiki/Dependency_hell) I was at a loss of how to make it work, until I ran across a cool project made by a Ph.D. student (Philip J. Guo) at Stanford called CDE: http://www.stanford.edu/~pgbovine/cde.html I will let you look at his explanations of how it works (I followed what he did in http://www.youtube.com/watch?feature=player_embedded&v=6XdwHo1BWwY, starting at about 32:00 as well as the directions on his site), but in short, it allows one to avoid dependency hell by copying all the files used when you run certain commands, recreating the linux environment where the command worked. I was able to use this to run LibreOffice without having to resort to someone's portable version of it, and it worked just like it did when I did it on Ubuntu with the command above, with a tweak: I needed to run the wrapper of LibreOffice the CDE generated. So, below is my PHP code that calls it. In this code snippet, the filename to be copied is passed in as $_POST["filename"]. I copy the file to the same spot where I originally converted the file, convert it, copy it back and then delete all the files (so that it doesn't start growing exponentially). I did it this way because I wasn't able to make it work otherwise on the webserver. If there is a linux + webserver ninja out there that can figure out how to make it work without doing this, I would be interested to know what you did. Please post a comment or something if you did that. <?php //first copy the file to the magic place where we can convert it to a pdf on the fly copy($time.$_POST["filename"], "../LibreOffice/cde-package/cde-root/home/robert/Desktop/".$_POST["filename"]); //change to that directory chdir('../LibreOffice/cde-package/cde-root/home/robert'); //the magic command that does the conversion $myCommand = "./libreoffice.cde --headless -convert-to pdf Desktop/".$_POST["filename"]." -outdir Desktop/"; exec ($myCommand); //copy the file back copy("Desktop/".str_replace(".docx", ".pdf", $_POST["filename"]), "../../../../../documents/".str_replace(".docx", ".pdf", $_POST["filename"])); //delete all the files out of the magic place where we can convert it to a pdf on the fly $files1 = scandir('Desktop'); //my files that I generated all happened to start with a number. $pattern = '/^[0-9]/'; foreach ($files1 as $value) { preg_match($pattern, $value, $matches); if(count($matches) ?> 0) { unlink("Desktop/".$value); } } //changing the header to the location of the file makes it work well on androids header( 'Location: '.str_replace(".docx", ".pdf", $_POST["filename"]) ); ?> And here is the tar.gz file I generated I generated with CDE. To duplicate what I did exactly, put the tar.gz file in a folder somewhere. I will call that folder the "root". Make a new folder called "documents" in the "root" folder. Unpack the tar.gz and run the php script above from the "documents" folder. Success! I made a truly portable version of LibreOffice that can convert files on the fly on a webserver using 100% free, open source software!

• Raphael JS - Parsing an SVG on the fly

  - by Chris

  I found a neat SVG parser at http://bkp.ee/atirip/ which parses an SVG file and outputs it into javascript that uses the Raphael JS library (raphaeljs.com). You'll notice in the source code at http://bkp.ee/atirip/svg2rdemo.php : <script> jQuery(document).ready( function() { $("#c1").each(function(){ var c = Raphael(this, 190, 154, 0, 0); var g1 = c.set(); ... it creates variables like g1, g2, etc. But it also reuses these variables. I would like to create unique variables for each group. In my .ai file, I have named my groups and I would like to use these names to create the variable names. Where in http://bkp.ee/atirip/f/svgToRaphaelParser.php.zip should I look to make this change?
