  • Adding Content to a Randomized Background

    - by user2903815
    On refresh my background image changes. I need to add a header to change with each background. How would I add an h1 tag to the php. I am unfamiliar with php but I feel like this should be an easy fix. Here's my script: <script type="text/javascript"> var bgcount = 3; function changebg() { var num = Math.ceil( Math.random() * bgcount ); document.body.background = 'bgs/'+num+'.jpg'; document.body.style.backgroundRepeat = "no-repeat"; document.body.style.backgroundAttachment = "fixed"; document.body.style.backgroundSize = "cover"; } </script> Thanks!

  • Create a picture with GD containing other images

    - by Jensen
    Hi, I would like to create a picture in PHP with GD composed by different other pictures. For example I have 6 pictures (or more) and I would like to create ONE picture who contain these different pictures. The Difficulty is that my final picture must have a fixed width and height (304x179), so if the different pictures are too big they must be cut. This is an example from IconFinder : This picture is composed by 6 images, but the 3rd bird (green) is cutted, and the 4, 5 and 6 are cutted in the bottom. This is what I want, can you give me some help to write this code in PHP ? Thanks

  • How to tell my asp.net page to use .net 3.5?

    - by kralco626
    My company recently upgraded from IE 6 to IE 8. My site does not render properly. I wanted to make sure my .net version was fixed before I started to try to fix a problem. I think my web.config file says i'm using 3.5, but if I get an error when running the app I get this: Version Information: Microsoft .NET Framework Version:2.0.50727.3603; ASP.NET Version:2.0.50727.3082 Why does it say 2.0? rather than 3.5? How do i change this? (using visual studio 2008, running the site locally) Thanks in advance!

  • WCF Diagnostics tracing and WAS hosting?

    - by Per Salmi
    I have a WAS hosted set of services configured to use net.tcp running under an IIS AppPool user account. When hosting the services with WAS I have a hard time getting any diagnostic tracing out of them to track down problems. The same services with tracing set to use i.e. c:\logs\trace.svclog as trace output works fine when using self-hosting in a console application. I don't seem to get any trace output at all when hosting with WAS, are there any special settings I need to get trace output under WAS? I have set a fixed output path for tracing and assigned permissions to the folder for the IIS AppPool\MyAppPool-user. /Per Salmi

  • Get ffmpeg information in friendly way

    - by JBernardo
    Every time I try to get some information about my video files with ffmpeg, it pukes a lot of useless information mixed with good things. I'm using ffmpeg -i name_of_the_video.mpg. There are any possibilities to get that in a friendly way? I mean JSON would be great (and even ugly XML is fine). By now, I made my application parse the data with regex but there are lots of nasty corners that appear on some specific video files. I fixed all that I encountered, but there may be more. I wanted something like: { "Stream 0": { "type": "Video", "codec": "h264", "resolution": "720x480" }, "Stream 1": { "type": "Audio", "bitrate": "128 kbps", "channels": 2 } }

  • Qt: Is it possible to tell a widget to take all the place that it has in layout, but not more?

    - by Lukasz Lew
    I have a following Qt code: QVBoxLayout* box = new QVBoxLayout; label = new QLabel(); // will be set later dynamically box->addWidget (label); Text in label will be set later. The problem is that when label resizes, it resizes QVBoxLayout, and it resizes other neighboring widgets. I don't want to make a label or layout fixed width. Because I want them to resize with a whole window. Is it possible to tell label to take all the place that it has in layout, but not more?

  • .htaccess rewrite issue with P

    - by Cyclone
    This is a followup for this question. When I used the proxy flag, I did not know all of its effects. Now I have two more problems, which need to be fixed! The main problem is with user IP addresses, everyone appears to use the server IP. I can't trust http-x-forwarded-for because it is easy to forge headers, and the REMOTE_ADDR just shows the server IP. I used the P flag because it acted as a mask, but Google loads everything with the actual URL. How can I use this subdomain rewrite without the P flag? It needs to be internal. Thank you for your help!

  • How to reset persistent scrollbar position after div refresh in FF3?

    - by rcon
    Hi, I'm experiencing a weird scrollbar issue. I'm building a page that uses jQuery and PHP to dynamically load images into a DIV sequentially. This DIV is a fixed height but uses a scrollbar for its variable width. The problem is that the scrollbar does not reset after a dynamic refresh of the DIV. So when the user scrolls and then refreshes with new content, the scroll bar position stays persistent instead of resetting back to the left. This seems to only happen in FF3. The scrollbar resets perfectly fine in Chrome, Safari, and IE8. For each refresh, the DIV is hidden, emptied, sized with CSS, then sequentially appended with images. I've tried resetting white-space: normal before the nowrap, playing around with overflow, and also jQuery's scrollLeft to no avail. It still behaves strangely in FF3, and only FF3. http://www.shadowshapes.com/uttdev/ Click a thumbnail, move the scrollbar then click another thumb. Thanks for any help!

  • Can't use MySQL extract() function in the WHERE clause.

    - by UkraineTrain
    I've run the following query: UPDATE main_table, reference_table SET main_table.calc_column = (CASE WHEN main_table.incr = "6AM" THEN reference_table.col1+reference_table.col2+... WHEN main_table.incr = "12AM" THEN reference_table.col7+reference_table.col8+... WHEN main_table.incr = "6PM" THEN reference_table.col13+reference_table.col14+... ELSE reference_table.col19+reference_table.col20+...) WHERE main_table.month = extract(month from reference_table.thedate) AND main_table.day = extract(day from reference_table.thedate) I've used extract() function since my reference_table doesn't have month and day columns but has the date column named thedate. I've used the extract() function on the reference_table many times before successfully, so, I know that there's nothing wrong with my extract function syntax. However, in this instance, MySQL complains. It probably has to do with the fact that I've used in the WHERE clause. I know that this issue could get fixed if I added the month and day columns to the reference_table to avoid using the extract() function. However, I'm very reluctant to do that and would like to avoid it. How can I make it work?`

  • 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.

  • simple search in rails

    - by Adnan
    Hi, I'm making a simple search form in rails. In my search view I have two select boxes with fixed values like: SELECT BOX 1 SELECT BOX 2 ALL, ALL, FR, FR, US, US, DE DE And I have 2 fields in my DB with country_from and country_to. So for making a simple search like from FR to US I use: @search_result = Load.find(:all, :conditions => "country_from='#{params[:country_from]}' AND country_to='#{params[:country_to]}'" ) that is fine, but I need to implement the ALL option as well, so when I make a search like from DE to ALL I get a list with all countries in country_to I image I can do it with ifs...but what would be the most efficient way to do it?

  • How to change the font size in table cells according to cells content ?

    - by misha-moroshko
    I have an HTML table which has incrementing numbers starting from 0 in its cells (left to right, up to bottom). I fixed in CSS the width and the height of the cells (40px width, 25px height, in my case). When the table becomes larger, the numbers inside it becomes large also (for example, the last number is 1266356). This causes the cells to be wider than I defined in the CSS, which expands the whole table accordingly. Instead, I would like the font of the numbers to be smaller to keep the width of the cell 40px. How can I accomplish this using CSS / Javascript / jQuery ?

  • Thread Suicide on Shutdown?

    - by yar
    I have a java.util.Timer running at a fixed interval. I have added a Runtime#addShutdownHook and it shuts down when the VM ends normally or abnormally. However, it keeps the VM alive when a main terminates, unless I insist by doing a System.exit in the main. Is there any way for me to check if I'm the last Thread standing, or some other way to avoid altering a main that would exit normally on finish? Note: I know a lot of people believe that java.util.Timer is deprecated (it's not), but unless your alternative helps me solve this problem...

  • validating radiogroup with perl/cgi

    - by Tyug
    Is it possible to validate a radio group (so something is checked off, or chosen) using server-side validation with Perl? If so, how? I already have it for JavaScript, but I want this form to be able to be submitted even without JavaScript enabled. Thus I will need the validation on the server-side. There is no fixed name for the radio group, it can change, however there must be a name, so that @names = $cgi->param() will give all the names. I'm thinking along something that will give me the type, like the type in JavaScript, to determine if it's a radio button in a group.

  • ValidateRect vs BeginPaint

    - by Armentage
    From the MSDN documentation: The BeginPaint function validates the entire client area. The ValidateRect function should not be called if a portion of the update region must be validated before the next WM_PAINT message is generated.1 I've been programming with Win32 API for years, and I've never thought to call the ValidateRect function. A co-worker of mine today pointed that we were missing a call to ValidateRect, which fixed a bug we were having doing some high-speed animation using GDI (I know, an oxymoron) Can someone tell me whether or not a call to ValidateRect is neccessary after a BeginPaint/EndPaint pair? I have seen no documentation at MSDN that sheds light on this, and what documentation and examples I do see that you do not need to.

  • How to make an element slide with the viewport as it scrolls?

    - by alex
    I've Googled for this but must be using the wrong keywords. Basically I want to use the effect that Magento and now Stack Overflow uses. That is, there is an element in a column, and when you scroll down, it sticks to the top of the viewport. And once scrolled up again, it goes back into the normal page flow. This Ask A Question is a good page for example. Scroll down and watch the "How to Format" element come down (might need to make your viewport smaller if you have a large screen to see the effect). I've noticed it is setting position: fixed in the CSS. The JavaScript however is obfuscated. What's the easiest way to achieve this effect? Is there a jQuery plugin available?

  • How do you combine a Move and Rotate effect in Flex 3?

    - by Impirator
    I realize you can make one of each effect, set the same target, and hit .play();, but this produces weird results (acknowledged by Adobe, fixed in Flex 4). I'm trying to have an object move from the top of the screen to the bottom while it rotates around it's own center. When called independently, both of these effects work perfectly. When called together, the object always rotates around the top left corner. I even tried putting them both inside a <Parallel> tag with no success. Has anyone come up with a workaround?

  • How to dynamically set div size?

    - by Vafello
    I have a div container with a text that has been previously typed in by the user. I would like to adjust the size of the div to this text. I cannot have fixed size because I dont know the length of the text. If there is no size specified div takes the width of entire window. This cause some problems for me because I am using JQuery draggable plugin and the scrollbars appear immediately when the div is dragged. Any advice on that?

  • .Net using Chr() to parse text

    - by Marcx
    I'm building a simple client-server chat system. The clients send data to the server and the server resends the data to all the other clients. I'm using the TcpListener and Network stream classes to send the data between the client and the server. The fields I need to send are, for example: name, text, timestamp, etc. I separate them using the ASCII character 29. I'm also using ASCII character 30 to mark the end of the streamed data. The data is encoded with UTF8.. Is this a good approach? Will I run into problems? Are there better methods? UPDATE: Probably my question was misunderstood, so I explain it better.. Suppose to have a list of data to send from client to server, and suppose to send all the data in only one stream, how do you send these data? Using a markup Using a character as a delimiter Using a fixed length for every fields

  • Reading from a file into an array in c

    - by NaNa21
    My file contains a series of numbers (integer, float, integer, float ....), each written on a separate line. The numbers of columns are different from one line to another i.e. 1 2.45 3 1.75 5 3.45 7 2.55 9 3.25 6 1.75 4 3.55 6 2.55 9 2.45 The program should read the contents of the entire file and place the data into an array of type float with an entry for each line. Here is my basic solution, but this is only suitable if I have fixed no of columns. float Read(FILE *pFile) { char line[50]; char letter[5]; fi = fopen("file.txt", "r"); while (fgets(line,200,fi)!=NULL) { sscanf(line,"%f %f %f",&a[i], &a2[i],&a3[i]); printf("%2.0f %2.5f %2.0f\n",a[i],a2[i],a3[i]); } fclose(fi); return a[i]; } Please HELP.

  • Handling orientation changes yourself

    - by synic
    From the documentation regarding the android:configChanges='orientation' attribute of the activity tag in the manifest: Note: Using this attribute should be avoided and used only as a last-resort. Please read Handling Runtime Changes for more information about how to properly handle a restart due to a configuration change. Why does it say this? In the case of threads and networking requests via a service API library, a request could be made with a reference to the original Activity, and then an orientation change could occur, leaving the thread pointing to the old Activity. While this can be fixed, it's tedious and ugly compared to just handling the configuration changes yourself. Why should it be avoided?
