• 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?

• 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 ?

• 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!

• Users lose access privileges every night

  - by armannvg

  Hi I'm having a problem with a WSS 3.0 instance where users keep losing their upload access rights every night. Users can always enter the Site involved and can browse lists, document libraries etc. just like normal, but they get an error when trying to upload documents, getting access denied error. This can be fixed by applying their access rights again in WSS, but it has to be done every morning, making that solution not feasible. This is a dedicated virtual server and no other applications running on it. Has anyone had a similar problem regarding WSS and Sharepoint access rights ?

• 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!

• PHP --> SQL Server + Excel file upload from a specific row

  - by lucky

  I have a requirement in which, i need to upload an excel file into SQL Server database. It is working well till this point. But sometimes i am getting excel file in such a way, that the first 2 rows and columns are empty rows. That is not even fixed every time. so the format of the table after upload is not as expected. It is assigning F1, F2 as column names for the table in SQL Server. It varies from file to file. I want to program it in such away so that the user can enter the row number and the column number from where the actual data is starting. So that while upload it should from line 3 and column 2. I don't know how to specify that row and column while uploading. Please help me to solve the same.

• Loop through different sets of unique permutations

  - by user558610

  Hi I'm having a hard time getting started to layout code for this problem. I have a fixed amount of random numbers, in this case 8 numbers. R[] = { 1, 2, 3, 4, 5, 6, 7, 8 }; That are going to be placed in 3 sets of numbers, with the only constraint that each set contain minimum one value, and each value can only be used once. For example: R1[] = { 1, 4 } R2[] = { 2, 8, 5, 6 } R3[] = { 7, 4 } I need to loop through all possible combinations of a set R1, R2, R3. Order is not important, so if the above example happened, I don't need R1[] = { 4, 1 } R2[] = { 2, 8, 5, 6 } R3[] = { 7, 4 } NOR R1[] = { 2, 8, 5, 6 } R2[] = { 7, 4 } R3[] = { 1, 4 } What is a good method?

• Git pull: error: Entry foo not uptodate. Cannot merge.

  - by yuit

  I'm trying to update my repo from a remote branch and keep getting this error when I do a "git pull". I haven't made any local changes, and even if I have I don't need to keep them. I've tried: git reset --hard and I get the same problem The only thing that seems to work is deleting the offending file and try a git pull again. I've also tried "git stash" followed by a "git pull". No go. edit: using PortableGit-1.6.4-preview20090729 so any previous bugs with spurious errors should be fixed.

• Unrecognized libraries and functions

  - by John Smith

  I am working in Eclipse 3.7.2 on Ubuntu 12.04 with C++. I have read about a few instances where libraries were not being recognized and the majority said to update the Paths and Symbols but that hasn't fixed my issue. I have 2 projects open in my workspace, one of which is already a completed project that has implemented functions and libraries with no errors from Eclipse. However, when I try to implement some of the same functions or include the same libraries in the 2nd project Eclipse can't resolve them. For example, #include <string> #include <stdio.h> strstr(p, "<Project>"); The include statement will be accepted and stdio.h will be found but the strstr function is not resolved even though it works fine in the other project. Any ideas as to why this might be happening? Thanks.

• Display popup window for a CD.

  - by SLC

  Got a CD with a bunch of tutorials etc. done in HTML. What I want is to have a browser window open with no toolbars, fixed width/height etc. because the content is designed to fit nicely into such a window. You can do this with window.open and put a bunch of parameters in, but this triggers popup blockers and activex warnings. Also it looks kinda bad, as the original window doesn't close without a hack that also generates problems. Is there a nice way I can achieve this effect? I could perhaps compile an .exe to autorun on the CD to launch this, but I wouldn't know how to get an .exe to open a window with toolbars etc. turned off.

• Getting the fractional part of a float without using modf()

  - by knight666

  Hi, I'm developing for a platform without a math library, so I need to build my own tools. My current way of getting the fraction is to convert the float to fixed point (multiply with (float)0xFFFF, cast to int), get only the lower part (mask with 0xFFFF) and convert it back to a float again. However, the imprecision is killing me. I'm using my Frac() and InvFrac() functions to draw an anti-aliased line. Using modf I get a perfectly smooth line. With my own method pixels start jumping around due to precision loss. This is my code: const float fp_amount = (float)(0xFFFF); const float fp_amount_inv = 1.f / fp_amount; inline float Frac(float a_X) { return ((int)(a_X * fp_amount) & 0xFFFF) * fp_amount_inv; } inline float Frac(float a_X) { return (0xFFFF - (int)(a_X * fp_amount) & 0xFFFF) * fp_amount_inv; } Thanks in advance!

• Docmd.TransferText question

  - by every_answer_gets_a_point

  b'h i will be programmatically importing a text file into a table. i have saved the import steps. i will use this: DoCmd.TransferText(TransferType, SpecificationName, TableName, FileName, HasFieldNames, HTMLTableName, CodePage) to do the import. this is what SpecificationName means: Specification Name The specification name for the set of options that determines how a text file is imported, exported, or linked. For a fixed-width text file, you must either specify a specification name or use a schema.ini file, which should be stored in the same directory as the imported, linked, or exported text file. i do need a specific specification; however i do not know how to specify one. when i manually imported a table, i did save the specifications for my import, however i do not know how to call this in the TransferText. does anyone know how to specify SpecificationName ?

• How to keep the first result of a function from Prolog?

  - by zuhakasa

  I need to write a customized function that will be called many times by other fixed functions. In this function, at the first called time, it will return the total number of lines of a file. The second called time of this function, forward, will return the number of lines in small sections of this file. My question is how I keep the first returned result(total number of lines of a file) and use it for the next called times of my function. I need to write or declare any thing only in this function(not in the caller). Something like this: myFunction(Input, MyResult, FirstResult) :- calculateInputFunction(Input, Result), !, MyResult is Result, ... . The problem is, every time myFunction is called, it receives different Input and returns different MyResult. But I would like to keep the first MyResult to use for next called times of myFunction. How can I do that? Thanks very much for your answer in advance.

• Horizontally spacing a row of images evenly

  - by Tesla

  I have a few rows of images like so <div class="row"> <img src="image.jpg" alt=""> <img src="image.jpg" alt=""> <img src="image.jpg" alt=""> <img src="image.jpg" alt=""> <img src="image.jpg" alt=""> </div> Each image has a different width, and there is also a different number of images on each row (4-6). I want to space the images evenly in the row, the row has a fixed width of 960px. I could do this by calculating the total empty space for each row and then dividing it among the images for a margin, but I was hoping there was something simpler that I could apply to every row instead of having to calculate and code a separate one for each row.

• Adding a border (Fixed3D) to an existing borderless application

  - by Aphelion

  Hi there, I have an .NET application that always starts itself with its border style to 'None', as it is supposed to be an full-screen application with a fixed resolution. However, i would like to add the window border (Fixed3D) to this window when the application starts so that I am able to move it around my desktop. My first idea was to have a tray app running, monitoring event messages, and somehow change the window style when this specific application starts. However, I am not sure if this will work and how to do this. Anyone that can point me in the right direction?

• 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?

• 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 } }

• Android ratings and listviews

  - by puppetmaster04

  I'd like to add a list of reviews of books to my Android app. Basically what I'm after is a fixed rating using the RatingBar and a ListView containing the snippet of the review for each review. Once clicked I want the list item to expand and fill with the text of the full review. I have the content of the snippet, full text, and rating, but don't know how best to go about the layout. Any ideas are ok, I don't need full code, but I would much prefer to keep it to XML layout.

• 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?

• How to achieve jQuery scrolling/overlay effect (video in description)

  - by waffl

  I have two columns. The left column contains text of dynamic lengths. The right column is of fixed height and will contain a set of images selected at random per page load. I am trying to create an effect where while the user scrolls, the Image 2 scrolls above Image 1. When it reaches the top, the Image 1 begins to scroll up until it disappears, then Image 3 comes in and repeats the process. As this is rather confusing, I made a short video describing the desired effect. Video - MP4 I have begun trying to get it working in this jsbin but am at a loss for when the user scrolls back down and also when more images are required. I am thinking my current path is not the right direction. I'm thinking that employing something like jQuery waypoints is more the direction I should be pursuing?
