• Vertically Align text in a Div

  - by shinjuo

  I am trying to find the most effective way to align text with a div. I have tried a few things and none seem to work. .testimonialText { position: absolute; left: 15px; top: 15px; width: 150px; height: 309px; vertical-align: middle; text-align: center; font-family: Georgia, "Times New Roman", Times, serif; font-style: italic; padding: 1em 0 1em 0; }

• Why does SQL Server 2000 treat SELECT test.* and SELECT t.est.* the same?

  - by Chris Pebble

  I butter-fingered a query in SQL Server 2000 and added a period in the middle of the table name: SELECT t.est.* FROM test Instead of: SELECT test.* FROM test And the query still executed perfectly. Even SELECT t.e.st.* FROM test executes without issue. I've tried the same query in SQL Server 2008 where the query fails (error: the column prefix does not match with a table name or alias used in the query). For reasons of pure curiosity I have been trying to figure out how SQL Server 2000 handles the table names in a way that would allow the butter-fingered query to run, but I haven't had much luck so far. Any sql gurus know why SQL Server 2000 ran the query without issue? Update: The query appears to work regardless of the interface used (e.g. Enterprise Manager, SSMS, OSQL) and as Jhonny pointed out below it bizarrely even works when you try: SELECT TOP 1000 dbota.ble.* FROM dbo.table

• Exponential volume control with a specified midpoint

  - by Lars

  I have a slider that returns values from 0 to 100. I am using this to control the gain of an oscillator. When the slider is at 0, I would like the gain to be 0.0 When the slider is at 50, I would like the gain to be 0.1 When the slider is at 100, I would like the gain to be 0.5 So I need to find an equation to get a smooth curve which passes through all of these points. I've got the following equation which gives an exponential curve and gets the start and end points correct, but I don't know how to force the curve through the middle point. Can anyone help? function logSlider(position){ var minP = 0; var maxP = 100; var minV = Math.log(0.0001); var maxV = Math.log(0.5); var scale = (maxV - minV) / (maxP - minP); return Math.exp(minV + scale*(position-minP)); }

• jQuery $.post & $.append & IE6

  - by Jim

  I'm having a weird problem with jQuery and IE6. Script works on IE7+ and with all other browsers I have tried it. I can't post the full script, but what it does is this: $.post("file.php",{'foo':'bar'},function(data){ $('#target').append(data) }) When I run the code in IE6, #target just shows ? and a white char with a hole in the middle. I have no idea what this second char is. My initial thought was that this was some sort of content-type problem because the file.php just echoes answer without any header information. I added Content-type: text/html with header() but didn't help. Any suggestions?

• horizontal align in a div

  - by Jason94

  I have a box like this: <div id="selectBox"> Select: <select> <option>1</option> <option>2</option> </select> </div> How do i get them aligned so that they are horizontal in the middle of each other, the baseline of the "Select" text and the content of the select box ("1").(and not the box itself). I can solv this by wrapping a table around them and make two cells but i feel that method is very crude.

• How do I get an Iterator over a vector of objects from a Template?

  - by nieldw

  I'm busy implementing a Graph ADT in C++. I have templates for the Edges and the Vertices. At each Vertex I have a vector containing pointers to the Edges that are incident to it. Now I'm trying to get an iterator over those edges. These are the lines of code: vector<Edge<edgeDecor, vertexDecor, dir>*> edges = this->incidentEdges(); vector<Edge<edgeDecor, vertexDecor, dir>*>::const_iterator i; for (i = edges.begin(); i != edges.end(); ++i) { However, the compiler won't accept the middle line. I'm pretty new to C++. Am I missing something? Why can't I declare an iterator over objects from the Edge template? The compiler isn't giving any useful feedback. Much thanks niel

• Established javascript solution for secure registration & authentication without SSL

  - by Tomas

  Is there any solution for secure user registration and authentication without SSL? With "secure" I mean safe from passive eavesdropping, not from man-in-the-middle (I'm aware that only SSL with signed certificate will reach this degree of security). The registration (password setup, i.e. exchanging of pre-shared keys) must be also secured without SSL (this will be the hardest part I guess). I prefer established and well tested solution. If possible, I don't want to reinvent the wheel and make up my own cryptographic protocols. Thanks in advance.

• Software automation testing

  - by dotnet-practitioner

  I work in a .net shop where we need to automate software testing. We write ASP.net web apps, web services, windows services, scheduled console application. Back end for all these applications is SQL Server. We would like to automate testing of any bug fixes, any where from web UI change to, middle tier .net code change to sql code change. This tool would be used by programmers to do unit test and played back in different test environments to ensure that bug fix is test correctly in all the environments including the produciton environment. This test would be executed by different teams such as QA, Build, and production site testers. What tool or approach do you recommend?

• Modifying object in AfterInsert / AfterUpdate

  - by Jean Barmash

  I have a domain object that holds results of a calculation based on parameters that are properties of the same domain object. I'd like to make sure that any time parameters get changed by the user, it recalculates and gets saved properly into the database. I am trying to do that with afterInsert (to make sure calculation is correct in the first place), and afterUpdate. However, since my calculation is trying to modify the object itself, it's not working - throwing various hibernate exceptions. I tried to put the afterUpdate code into a transaction, but that didn't help. I am afraid I am getting into a circular dependency issues here. The exception I am getting right now is: org.hibernate.StaleObjectStateException: Row was updated or deleted by another transaction (or unsaved-value mapping was incorrect): [esc.scorecard.PropertyScorecard#27] Are the GORM events designed for simpler use cases? I am tempted to conclude that modifying the object you are in the middle of saving is not the way to go.

• How to float span properly

  - by brianr1

  I am developing this site http://indigonightlife.com/ The second section down is This Weeks Events. To the right of that heading is an image of the 5 little blue lines. The problem Im having is I cant get it to float to the right side of the container. As it is now, its in the middle of the container. Ive tried all kinds of combos of floats, clearfixes, and such but I cant get it to stay to the right. The section below titled Resident and Guest DJs has the same image but its floated fine. Not sure what the difference is. Any help would be appreciated. Thanks.

• Referencing control on one form from another form VB.NET

  - by Tom

  My gosh man, why is this so complicated in VB.NET? As you can guess, I'm kind of new to .NET and just want to reference a control on one form from another. Usually I would just do Form.Control.Property but that doesn't work and every example I've found through Google doesn't work for me. It just seems overly complicated with public classes, etc. Is there a more simpler way to do this? I'm ready to throw in the towel and just use a global variable at this point. I have the form containing the control I want to reference, frmGenerate which has a textbox called txtCustomerNo. From this form through a button's click event I want to show another form, frmCustomers, and have that form reference the value in txtCustomerNo. frmCustomers.ShowDialog() It has to be something simple that I'm just not grasping. Thanks.

• Do you leave Windows Automatic Updates enabled on your production IIS server?

  - by Nobody

  If you were running a 24/7 website on Windows Server 2003 (IIS6). Would you leave the Windows automatic update feature enabled or would you turn it off? When enabled, you always get the latest security patches and bug fixes automatically as soon as they're available, which is the most secure choice. However, the machine will sometimes get automatically rebooted to apply the updates leading to a couple of minutes of downtime in the middle of the night. Also, I've seen rare occasions where the machine does not restart correctly resulting in further downtime. If auto updates are off, when do you apply the patches? I guess you have to use a load balancer with multiple web servers and rotate them out of the production site, apply patches manually, and put them back in. This can be logistically inconvenient when the load balancer is managed by a hosting company. You will also have machines in production that don't always have the latest security patches and you have to routinely spend time deciding which patches to apply and when.

• 3 fixed Columns (header and footer) using DIVs, NO Absolute DIVs, IE friendly, ALL columns stretch e

  - by Phillip Schein

  Left to right, Col1 id 560px wide with 10 px padding, middle column, 250px wide with 5px padding and Col3 (siderbar) is 200px wide with 3px padding. Background coloR, no matter text length in any column should stretch vertically equal. No javascript (jQuery workarounds) to make it work. It needs to be pure Semantic Markup with CSS. Each Column should have a nested column of color were content will go. Column 1 should be SEO prominant which means the highest nested column for Google and other Search Engines to crawl. I have used 'The Holy Grail" layout, articles at "A List Apart" and these solution are so convoluted that they push the main columns left and than the nested columns push them with padding back right. This is crazy! I try to adjust these examples, but they're not editable by just adjusting a width in the CSS or the padding, etc. Can you please help me?

• Get other classes from an element with Jquery

  - by Jigs

  I am working on a small bit of script that will allow for easy and flexible creation of buttons. My buttons are made of three parts, a left, a right and a streched middle piece. There are three different sizes and three different colours of each. I have written the code that resizes the button to fit the text. Now I am looking to add the ability to easily set the colour and size. I was thinking of using three classes something like <div class="button blue big"> My script already loops through the button classes using each. Now I need to find out what other classes are set and adjust the pictures and dimentions used to fit. So how can I find out what other class selectors an element has? Also I am fairly new to jquery/javascript so I am wondering if storing the design as class selectors is the best way.

• How is fseek() implemented in the filesystem?

  - by pajton

  This is not a pure programming question, however it impacts the performance of programs using fseek(), hence it is important to know how it works. A little disclaimer so that it doesn't get closed. I am wondering how efficient it is to insert data in the middle of the file. Supposing I have a file with 1MB data and then I insert something at the 512KB offset. How efficient would that be compared to appending my data at the end of the file? Just to make the example complete lets say I want to insert 16KB of data. I understand the answer varies depending on the filesystem, however I assume that the techniques used in common filesystems are quite similar and I just want to get the right notion of it.

• Why does the infobox in my MSN Map not close?

  - by meder

  I'm having a bit of trouble with this map, invoked by the "View our interactive map" button in the middle of the content area. If you double click a point such as 8 which causes a zoom and then afterwards it causes the info box to appear, the hide logic is wrong. If you try to close the x, it will fail. This is probably because the user clicked too fast and the map thinks its in zoom mode when infact it should be in info box mode. Has anyone ran into this issue before? Looks like I have to mess around with window.ero.hide and some other functions.. because map.HideInfoBox doesn't hide the map. EDIT: The script used is here. I did not code it, but the relevant bit has: onclick="EnableEroHide();map.HideInfoBox();changePin();return false;" The map.HideInfoBox() should hide the info box.

• opening iWorks documents in iPad UIWebView

  - by user369156

  Hello, I'm writing an iPad application that has a UIWebView which I open word and excel documents in, but I want the user to be able to import those documents into the iWorks applications, Pages and Numbers, just like how you can do it in Safari if you open a document. If you open a document in Safari on the iPad, there'll be a button on the top bar that says "Open in..." and you can choose applications to open in. You get the top bar to appear by tapping on middle of the page. So is there an option you can set to allow UIWebView to show up the bar and automatically detect the content type and populate the list with applications you can import in? Or do I have to build this myself? And if I have to build my own, how do I open URLs to import documents into Pages and Numbers etc? Thanks, -David

• basename() returning int?

  - by EB

  Probably something stupid I'm missing but, why am I getting this warning? static void foo(char *path) { char *bname; char *path2 = strdup(path); bname = basename(path2); (line with basename() call): warning: assignment makes pointer from integer without a cast Indeed, if I change to this, the warning goes away: bname = (char *)basename(path2); man 3 basename tells me: char *basename(char *path); Both dirname() and basename() return pointers to null-terminated strings. What gives?

• MATLAB: Can axes tick labels be accesed as text objects?

  - by yuk

  I'm curious is it possible to change text properties of tick labels independently of axes properties. Do they have handles? I'd like to control their position better, alignment, color, fonts, etc. I know I can substitute them with text labels, but it has some drawbacks. Any alternative solutions? Particularly, is it possible to put xticklabels between ticks, that are irregular? plot(1:100) set(gca,'xtick',[30 45 53 70 95]) grid on I need to put xticklabels in the middle between grids.

• C++ Boost ASIO: how to read/write with a timeout?

  - by Stéphane

  From reading other Stackoverflow entries and the boost::asio documentation, I've confirmed that there is no synchronous asio read/write calls that also provide an easy-to-use timeout as a parameter to the call. I'm in the middle of converting an old-school linux socket app with select(2) calls that employs timeouts, and I need to do more-or-less the same. So what is the best way to do this in boost::asio? Looking at the asio documentation, there are many confusing examples of various things to do with timers, but I'm quite confused. I'd love to see a simple-to-read example of this: Read from a socket, but wait for a maximum of X seconds after which the function either returns with nothing, or returns with whatever it was able to read from the socket before the timeout expired.

• Download files using Perl

  - by Neeraj

  I have a project that depends upon some other binaries to be downloaded from web at install time.For this what i do is: if ( file-present-in-src/) # skip that file else # use wget to download the file The problem with this approach is that when I interrupt a download in middle, and do invoke the script next time, the partially downloaded file is also skipped (which is not desired), also I want wget to resume the download of the partially downloaded file. How should I go about it: Possible Solutions I could think of: Let the file to be downloaded to some file say download_tmp. Copy to original file if successful. Handle SIG{'INT'} to write proper cleanup code. But none of these could help resume the partial file download, Any insights?
