is there way can like @sorttype select * table order -- if sorttype == id table.id -- else if sorttype == date table.date how syntax look? thanks. there's gotcha here... can't mix data types in case statement, need create different groups of case statements different data types. select * table order case when @sorttype = id table.id end asc, case when @sorttype != id table.date end asc related blog post: http://dirk.net/2006/11/14/dynamic-order-by-with-case-statement-in-sql-server-data-type-issues/

i'm writing simple j2me game uses png images 8-bit alpha channel. problem: not hardware supports full alpha transparency rendering. however, since game pretty static in nature (at beginning, "sprites" layed out onto background image, based on current screen size, , that's it), thought possible prerender transparent images directly onto background during game initialization , use later in game. can't prerender them in photoshop positions not known in advance. but, seems there no way read original alpha channel on devices not support semi-transparency gets resampled during png loading. there library can that? or idea store alpha channels separately (e.g. separate 8-bit png images) , manually apply them? thanks! png images have transparency support if want create transparent image have read rgb data along alpha channels , process alpha image transpng=image.createimage("/trans.png"); //load tranparent image int rgbdata[]; transpng.getrgb(

i have simple text file ~150mb. code read each line, , if matches regexes, gets written output file. right now, takes long time iterate through of lines of file (several minutes) doing file.open(filename).each |line| # stuff end i know looping through lines of file taking while because if nothing data in "#do stuff", still takes long time. i know unix programs can parse large files instantly (like grep), wondering why ruby (mri 1.9) takes long read file, , there way make faster? file.readlines.each |line| #do stuff each line end will read whole file 1 array of lines. should lot faster, takes more memory.

i'm using 3 images side-by-side, , adding url.action each 1 of them. code works fine, images being displayed w/ sort of line between them. here code: <a href="@url.action("subcribe", new { id = item.id })"> <img src="images\subscribe.png" style="border:0" alt="subscribe" /> </a> <a href="@url.action("edit", new { id = item.id })"> <img src="images\edit.png" style="border:0" alt="edit" /> </a> <a href="@url.action("delete", new { id = item.id })"> <img src="images\delete.png" style="border:0" alt="delete" /> </a> edit - happening when tried alternate, non-url.action method: <a href="subcribe\@item.id"> <img src="images\subscribe.png" style="border:0" alt="subscribe" /> </a> here how images displa

i have seen many similar questions 1 think still covers new ground: 1) hint text disappears when set gravity 2) android:ellipsize="start" fixes can have centered hints , centered text 3) why code below still show centered hint text? <edittext android:id="@+id/details" android:layout_width="fill_parent" android:layout_height="wrap_content" android:gravity="center" android:hint="use area provide specific identification information including approximate size, vessel name , registration numbers if available" android:background="@android:drawable/editbox_background" android:layout_below="@id/details_title" /> is because of fill_parent instead of wrap_content? thought maybe because hint multiline, shortened , still appeared , centered. differences between , other edittexts needed android:ellipsize="start" display correctly. bug? you need u

is possible increment application badge through local notification while app not running? i know how set badge, haven't found way increment value. localnotification.applicationiconbadgenumber = 23; update: found (far being perfect) solution. can predict happen, if user doesn't open app , add notifications every +1 event. an example: for day 1: count = 0 for day 2: localnotification.applicationiconbadgenumber = 1; for day 3: localnotification.applicationiconbadgenumber = 2; for day 4: localnotification.applicationiconbadgenumber = 3; ==> put these notifications in array , set them before application exits. however, i'm searching better solution workaround. the way you're going able dynamically set badge number when application isn't running push notifications. you'll have track updates on server side.

i need iterate through infopath templates (xsn files) , change url of data connections, , save changes templates. the data connections want change, points lists in sharepoint environment. so, how accomplish task? i thinking doing console application. infopath doesn't make easy deploy different servers. have used powershell script can use console app or scripting language. steps follow: 1. extract files xsn (either use extrac32 util ms or rename zip , use zip library) 2. change data connection (string replace) in manifest.xsf, template.xml, , sampledata.xml 3. repackage files xsn (either use cabarc util ms or zip , rename) it pain have entire script less page long , runs pretty fast. 1 caveat ran needed delay between steps 1 , 2 - files weren't finished extracting , script trying change them.
