  • Excel Autofilter in VB.NET

    - by Fabri
    In my application I'm exporting an Excel file by getting the layout of a HTML page. So, in my codebehind, I'm modifying the HTML layout and inserting itens on it like if it was a webpage. Doing it that way, I don't need to use any external library and, as the data I'm exporting is just a table, I don't need nothing complex to handle it. My question is: there is a way to create an AutoFilter by just modifying the HTML tags? I mean, like if a put a < bColumn Name in the HTML, when exporting to Excel it will become Bold, it is possible to do the same thing with the AutoFilter?

  • please help me understand libraries/includes

    - by fiftyeight
    I'm trying to understand how libraries work. for example I downloaded a tarball and extracted it. Now I do "./configure", it searches in pre-defined directories from what I understand for certain library files. What does it do then? it creates a makefile, and the makefile contains the paths to these libraries? than I do "make", it complies the source code and hard-codes the locations of the libraries? am I correct? I do not really understand if libraries are files with pre-defined paths or the OS somehow gives access to the libraries through system calls. another example, I complied something on my computer than moved it to a remote server, the executable needs mysql libraries to work, the server has mysql but for some reason when execute the file it tells me "can't find libmysqlclient.so.16". is there a solution for this? is there a way to know where is tries to locate this file or give it another path? I can't compile it on the server since it has no compiler and I don't have root access to install packages last question is if in the sequence "./configure","make","make install" the "make install" command is the only one that actually puts files outside the directory in which these files reside? if for example the software will be installed in /usr/local/ is the "make install" command the only one that will require "sudo" before it? let me see if I got it correctly: "./configure" creates the Makefile according to the location of various files on your system. "make" compiles the source code according to this makefile. and "make install" moves the files to their appropriate location. I know this has been very long I thank anyone who had the patience to read my question :)

  • How does throwing an ArgumentNullException help?

    - by Scott Whitlock
    Let's say I have a method: public void DoSomething(ISomeInterface someObject) { if(someObject == null) throw new ArgumentNullException("someObject"); someObject.DoThisOrThat(); } I've been trained to believe that throwing the ArgumentNullException is "correct" but an "Object reference not set to an instance of an object" error means I have a bug. Why? I know that if I was caching the reference to someObject and using it later, then it's better to check for nullity when passed in, and fail early. However, if I'm dereferencing it on the next line, why are we supposed to do the check? It's going to throw an exception one way or the other. Edit: It just occurred to me... does the fear of the dereferenced null come from a language like C++ that doesn't check for you (i.e. it just tries to execute some method at memory location zero + method offset)?

  • Disable MathML output of eLyXer

    - by Gryllida
    eLyXer is a standalone LyX to HTML converter. In the resulting file, equations are formatted as MathML, and the file itself starts with an XML tag. This causes two problems: LibreOffice does not read the XML file (it can read HTML files, but not XHTML). I am unable to copy and paste the equations into a document editor such as LibreOffice with the goal of subsequent conversion into .doc, because .doc files do not support MathML. The eLyXer help page mentions an option to only use simple math, but there is no option to set math equations to output as images. And I already set Document Settings Output Math equations Format: images in LyX, which presumably is saved in the lyx document somewhere. A web search did not come up with any solutions.

  • My multipart email script sends HTML messages just fine, but the plain text alternative doesn't not

    - by hsatterwhite
    I have a script set up to send out multipart emails; plain text and html messages. The HTML messages work just fine, but when I used an email client that only does plain text the plaint text message does not render and I get the following: -- This message was generated automatically by Me http://www.somewebsite.com/ $html_msg = $message_details; $plain_text_msg = strip_tags($message_details); $headers = <<<HEADERS From: Me <[email protected]> MIME-Version: 1.0 Content-Type: multipart/alternative; boundary="==PHP-alt$mime_boundary" HEADERS; // Use our boundary string to create plain text and HTML versions $message = <<<MESSAGE --==PHP-alt$mime_boundary Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 7bit $plain_text_msg -- This message was generated automatically by Me http://www.somewebsite.com/ If you did not request this message, please notify [email protected] --==PHP-alt$mime_boundary Content-Type: text/html; charset="iso-8859-1" Content-Transfer-Encoding: 7bit <html> <body> $html_msg <p> --<br /> This message was generated automatically as a demonstration on <a href="http://www.somewebsite.com/">Me</a> </p> <p> If you did not request this message, please notify <a href="mailto:[email protected]">[email protected]</a> </p> </body> </html> --==PHP-alt$mime_boundary-- MESSAGE;

  • Help to understand the abstract factory pattern

    - by Chobeat
    I'm learning the 23 design patterns of the GoF. I think I've found a way to understand and simplify how the Abstract Factory works but I would like to know if this is a correct assumption or if I am wrong. What I want to know is if we can see the result of the Abstract Factory method as a matrix of possible products where there's a Product for every "Concrete Factory" x "AbstractProduct" where the Concrete Factory is a single implementation among the implementations of an AbstractFactory and an AbstractProduct is an interface among the interfaces to create Products. Is this correct or am I missing something?

  • Html Buttons with Triangles [migrated]

    - by Dmitry
    I'm looking for the simplest way of creating 'buttons' with bootom-central triangles as follows: |--------| | Text | |---\/---| By buttons/menu items I mean something which will will support atomic mouse behavior for the whole shape's region. No rounded corners just the shape itself. I saw plenty of websites doing thsese buttons lately, but now for some strange reason I couldn't find any. Ideally I'm looking for tutorial links or some general guidances, as the topic might be too big to be covered by one post. Technology scope wise - ideally I'm looking for Html5/Css3 solution. I don't care mouch about old IE support and I think Html5/css3 will give a slicker/more elegant solution. On the way forward I might need to add drop shadows, which is another argument in favour of css3. Thanks.

    Write a program that prompts the user to enter the size of the array, allocate memory using malloc(), ask the user to enter elements of the array and displays if the puzzle is solvable. As part of this program, write a recursive function int Solvable(int start, int squares[]) that takes a starting position of the marker along with the array of squares. The function should return 1 if it is possible to solve the puzzle from the starting configuration and 0 if it is impossible

  • HTML5 tags not working at all in firefox 3.6.3

    - by William
    Okay, so I'm trying to get into this whole HTML 5 thing, and this tutorial (http://www.webreference.com/authoring/languages/html/HTML5/) says that these tags should move the content around without any kind of CSS at all, but all I'm getting is a line of text that looks like this: Header tag Nav tag Artical Section tags Aside tag footer tag Here is the code: <!DOCTYPE html> <html lang="en"> <head> <title>HTML5 test1</title> <meta charset="utf-8" /> </head> <body> <header> Header tag </header> <nav> Nav tag </nav> <article> <section> Artical Section tags </section> </article> <aside> Aside tag </aside> <footer> footer tag </footer> </body> </html>

  • Can anyone help solve this complex algorithmic problem?

    - by Locaaaaa
    I got this question in an interview and I was not able to solve it. You have a circular road, with N number of gas stations. You know the ammount of gas that each station has. You know the ammount of gas you need to GO from one station to the next one. Your car starts with 0. The question is: Create an algorithm, to know from which gas station you must start driving. As an exercise to me, I would translate the algorithm to C#.

  • Would installing debugging symbols help for reporting bugs?

    - by Chris
    I'm running a beta version of Ubuntu (12.10) and I've been reporting crashes through apport's automated system. I've glanced at the stacktraces for a couple of the issues and noticed a lot of what look like hex addresses and these: "No symbol table info available." I was wondering if installing the debugging symbols packages from synaptic would provide better information to package maintainers when I report bugs. In other words, would the stacktrace be more useful if I installed those packages? If so, would installing those packages make any (noticeable) performances differences (will my computer run slower)? Thanks, Chris

  • Change the content type of a pop up window.

    - by Oscar Reyes
    This question brought a new one: I have a html page and I need it to change the content type when the user press "save" button so the browser prompt to save the file to disk I've been doing this in the server side to offer "excel" versions of the page ( which is basically a html table ) <c:if test="${page.asExcelAction}"> <% response.setContentType("application/vnd.ms-excel"); %> What I'm trying to do now is to do the same, but in the client side with javacript but I can't manage to do it so. This is what I've got so far: <html> <head> <script> function saveAs(){ var sMarkup = document.getElementById('content').innerHTML; //var oNewDoc = document.open('application/vnd.ms-excel'); var oNewDoc = document.open('text/html'); oNewDoc.write( sMarkup ); oNewDoc.close(); } </script> </head> <body> <div id='content'> <table> <tr> <td>Stack</td> <td>Overflow</td> </tr> </table> </div> <input type="button" value="Save as" onClick="saveAs()"/> </body> </html>

  • Having trouble with projection matrix, need help

    - by Mr.UNOwen
    I'm having trouble with what appears to be the projection matrix. Given a wide enough of a screen, when a cube is on the left and right most edge, the left or right wall will appear stretched to the point that the front face is 1/10 the width of the side. So I do update the screen ratio along with the projection matrix and view port on screen resize, am I safe to assume all the trouble is from the matrix class? Also the cube follows the mouse, but it's only vertically aligned and ahead of the mouse when going left or right from the center of the screen. Perspective function call: * setPerspective * * @param fov: angle in radians * @param aspect: screen ratio w/h * @param near: near distance * @param far: far distance **/ void APCamera::setPerspective(GMFloat_t fov, GMFloat_t aspect, GMFloat_t near, GMFloat_t far) { GMFloat_t difZ = near - far; GMFloat_t *data; mProjection->clear(); //set to identity matrix data = mProjection->getData(); GMFloat_t v = 1.0f / tan(fov / 2.0f); data[_AP_MAA] = v / aspect; data[_AP_MBB] = v; data[_AP_MCC] = (far + near) / difZ; data[_AP_MCD] = -1.0f; data[_AP_MDD] = 0.0f; data[_AP_MDC] = 2.0f * far * near/ difZ; mRatio = aspect; mInvProjOutdated = true; mIsPerspective = true; } and... #define _AP_MAA 0 #define _AP_MAB 1 #define _AP_MAC 2 #define _AP_MAD 3 #define _AP_MBA 4 #define _AP_MBB 5 #define _AP_MBC 6 #define _AP_MBD 7 #define _AP_MCA 8 #define _AP_MCB 9 #define _AP_MCC 10 #define _AP_MCD 11 #define _AP_MDA 12 #define _AP_MDB 13 #define _AP_MDC 14 #define _AP_MDD 15

  • Need help with a complex 3d scene (using Ogre and bullet)

    - by Matthias
    In my setup there is a box with a hole on one side, and a freely movable "stick" (or bar, tube). This stick can be inserted/moved through the hole into the box. This hole is exactly as wide as the diameter of the stick. In reality, when you would now hold the end of the stick in your hand and move the hand left/right or up/down, the other end of the stick, which is inside the box, would move into the opposite direction of your hand movement (because the stick is affixed at the pivot point where it is entering the box through the hole). (I hope you understand what I mean so far.) Now I need to simulate such a setup in a 3d program. I have already successfully developed an Ogre3d framework for this application, including bullet. But what I don't know is how I can implement in my program what I have described above. This application must include two more features: The scene camera is attached to the end of the stick that is inserted into the box. So when the user would move the mouse (to control "his" end of the stick outside the box), then the camera attached to the stick would move in the opposite direction, as described above. The stick has some length, and the user can push it further into the box, or pull it closer to him again. That means of course that the max. radius on which the end of the stick inside the box can move depends on how far the stick is pushed into the box. Thus, the more the stick is pushed into the box, the larger the max. radius of this end of the stick with the camera will be. I understand this is maybe quite a complex thing, so I don't expect any real source code here. I already have the Ogre and bullet part as said up and running, as well as a camera attached to the stick. This works fine. What I don't know though is how I can simulate the setup described above. Especially the requirement that the stick is affixed at the position of the hole on the box, where it is inserted into the box. Any ideas how I could approach to implement the described setup?

  • Functional Programming - Does Knowing It Help Job Prospects?

    - by Jetti
    The main language that I use at the moment is C# and I am the most comfortable with it. However, I have started dabbling in F# and Haskell and really enjoy those langauges. I would love to improve my skills in either of those languages over time since it truly is fun for me to use them (as opposed to Ruby, which is hyped as "fun", I just don't get where the fun is, but I digress...). My question is directed at those who have hired/interviewed for programming positions (junior/mid-level): if you see a functional programming language on a resume, does it affect your opinion (whether positive or negatively) of that candidate? My rationale for knowledge of functional programming affecting the view of a candidate is because it can show that the candidate can adapt to different methodologies and take a mulit-dimensional approach to problems rather than the "same old OO approach". (This may be off-base, please let me know if this assumption is as well!)

  • Need Help Unable to Mount Location

    I am not able to start Windows and am using a DVD copy of Ubuntu to start up. I see my 750 GB Hard Disk, but if I click it i get this error: Error mounting: mount exited with exit code 13: ntfs_attr_pread_i: ntfs_pread failed: Input/output error Failed to read NTFS $Bitmap: Input/output error NTFS is either inconsistent, or there is a hardware fault, or it's a SoftRAID/FakeRAID hardware. In the first case run chkdsk /f on Windows then reboot into Windows twice. The usage of the /f parameter is very important! If the device is a SoftRAID/FakeRAID then first activate it and mount a different device under the /dev/mapper/ directory, (e.g. /dev/mapper/nvidia_eahaabcc1).

  • How do I get the element after my horizontal css navigation bar to appear below it?

  • Some Adsense domain's ads are causing document.write() statements that remove the html from the page

    - by er1234
    All that is output on the page is the domain name of the advertiser, for example 'www.solar-aid.org'. The rest of the content is stripped, I believe because of a document.write() statement. I'd like to know if this is a common issue or something wrong with our setup. There are three domains causing the issue, which we've blocked from Adsense as a result. solar-aid.org kiva.org grameenfoundation.org Given the type of organizations I think they may be within the default group of 'public service ads' within the Backup Ads setting. If the issue doesn't completely resolve itself soon (one customer of ours complained today, even though I blocked them 5+ days ago), I'll disable public service ads and select the 'fill space with a solid color' option.
