• javascript/jquery input fields cleanup

  - by user271619

  I've created a few input fields, that I am cleaning up as the user types. So, I'm using a keystroke detection event, like .keyup() It's all working very well, but I do notice one thing that's rather annoying for the users. While the script is cleaning the data as they type, their cursor is being sent to the end of the input field. So, if you want to edit the middle of the value, you're cursor immediately goes to the end of the box. Does anyone know of a way to maintain the cursor's current position inside the input field? I'm not holding my breath, but I thought I'd ask. Here's the cleanup code I'm using: $(".pricing").keyup(function(){ // clean up anything non-numeric **var itemprice = $("#itemprice").val().replace(/[^0-9\.]+/g, '');** // return the cleaner value back to the input field **$("#itemprice").val(itemprice);** });

• Subscription payment processing with ASP.NET

  - by bobsmith123

  I would like to create a subscription based website with users getting charged every month. I know I have to create an account with paypal or authorize.net. Do these payment providers automatically bill the user every month? How would I take care of offering the service free for 30 days and start billing after that? Also, I've heard of middle men services like spreedly, chargify. Where do they fit into the equation? Can someone help me wrap my head around these concepts? Considering, I am based in the U.S but would like to have the payment provider accept any kind of currency. Which payment provider do you suggest?

• Converting "is null" into a linq to sql statement

  - by Darryl Braaten

  I am having trouble replicating the following sql as a LINQ statement select TableA.* from TableA left outer join TableAinTableB on TableA.Id = TableAId where TableBId is null The following returns no lines from TableA in db.TableA join AinB in db.TableAinTableB on TableA.Id equals TableAId where AinB.TableBId == null select TableA Also tried and a few other things that didn't work. from TableA in db.TableA join AinB in db.TableAinTableB on TableA.Id equals TableAId where AinB == null select TableA TableAinTableB is a many to many table. The query I want will pull all the records from TableA that have no records in the middle table. My sql does what I want but I have no idea how to convert it to LINQ to SQL. I ended up working around it by just doing a db.ExecuteQuery("working sql"); But I would like to know if the query is possible in LINQ and how to write it, or a pointer to a document that covers this scenario. My searching did not uncover anything I found useful.

• How to wrap text of html button with fixed width

  - by Peter

  I just noticed that if you give a html button a fixed width, the text inside the button is never wrapped. I've tried it with word-wrap, but that cuts of the word even though there are spaces available to wrap on. How can I make the text of an html button with a fixed width wrap like any tablecell would? <td class="category_column"> <input type="submit" name="ctl00$ContentPlaceHolder1$DataList1$ctl12$ProCat_NameButton" value="Roos Sturingen / Sensors" id="ctl00_ContentPlaceHolder1_DataList1_ctl12_ProCat_NameButton" class="outset" style="height:118px;width:200px;font-size:18px;color:#7F7F7F;width:200px;white-space:pre;" /> </td> the css classes do nothing but adding borders and modify the padding. If I add word-wrap:break-word to this button, it will wrap it like this: Roos Sturingen / Sen sors And I dont want it to cut of in the middle of a word if it is possible to cut it off between words. Thanks

Not sure why IE6 and FireFox displaying text box of diff size.

• R: How to tell lapply to ignore an error and process the next thing in the list?

  - by John

  I have an example function below that reads in a date as a string and returns it as a date object. If it reads a string that it cannot convert to a date, it returns an error. testFunction <- function (date_in) { return(as.Date(date_in)) } testFunction("2010-04-06") # this works fine testFunction("foo") # this returns an error Now, I want to use lapply and apply this function over a list of dates: dates1 = c("2010-04-06", "2010-04-07", "2010-04-08") lapply(dates1, testFunction) # this works fine But if I want to apply the function over a list when one string in the middle of two good dates returns an error, what is the best way to deal with this? dates2 = c("2010-04-06", "foo", "2010-04-08") lapply(dates2, testFunction) I presume that I want a try catch in there, but is there a way to catch the error for the "foo" string whilst asking lapply to continue and read the third date?

• How do I antialias the clip boundary on Android's canvas?

  - by Jesse Wilson

  I'm using Android's android.graphics.Canvas class to draw a ring. My onDraw method clips the canvas to make a hole for the inner circle, and then draws the full outer circle over the hole: clip = new Path(); clip.addRect(outerCircle, Path.Direction.CW); clip.addOval(innerCircle, Path.Direction.CCW); canvas.save(); canvas.clipPath(clip); canvas.drawOval(outerCircle, lightGrey); canvas.restore(); The result is a ring with a pretty, anti-aliased outer edge and a jagged, ugly inner edge: What can I do to antialias the inner edge? I don't want to cheat by drawing a grey circle in the middle because the dialog is slightly transparent. (This transparency isn't as subtle on on other backgrounds.)

• Continuous builds and Agile vs commit often

  - by Mark Underwood

  Hi All, I'm just doing some formal training in Agile at the moment and one question I have is about the value of Continuous Builds vs value of committing to the version control system often. My understanding with version control is that its better to commit often, because then you have history and the ability to go back to previous changes in a fine grained way. My understanding with Agile and continuous build is that its there to put pressure on the developers to always have working code. That to break the source tree is a taboo thing to do. Now i agree with both of these sentiments, but it occurs to be that sometimes these might be working against each other. You maybe in the middle of a largish code change and want to commit code to make sure you have history, but this will break the source tree. Anybody got any thoughts on this? Cheers Mark.

• HTML: upload-form in an other form

  - by chris

  hi! I have a little problem with an upload-form within an other form (call it data-form). I know it is not possible to put a form into an other. So I would need to put it after my data-form. But I need the upload-form controls in the middle of my data-form because of optical and structural reasons. The file-upload should also perform other actions and not the same than the data-form. So any idea how can I make the upload-form after my data-form but visible in it or any other ideas to handle this? I am using javascirpt and php also. thanks and best wishes for 2011! br,chris

• strange syntax error in python, version 2.6 and 3.1

  - by flow

  this may not be an earth-shattering deficiency of python, but i still wonder about the rationale behind the following behavior: when i run source = """ print( 'helo' ) if __name__ == '__main__': print( 'yeah!' ) #""" print( compile( source, '<whatever>', 'exec' ) ) i get :: File "<whatever>", line 6 # ^ SyntaxError: invalid syntax i can avoid this exception by (1) deleting the trailing #; (2) deleting or outcommenting the if __name__ == '__main__':\n print( 'yeah!' ) lines; (3) add a newline to very end of the source. moreover, if i have the source end without a trailing newline right behind the print( 'yeah!' ), the source will also compile without error. i could also reproduce this behavior with python 2.6, so it’s not new to the 3k series. i find this error to be highly irritating, all the more since when i put above source inside a file and execute it directly or have it imported, no error will occur—which is the expected behavior. a # (hash) outside a string literal should always represent the start of a (possibly empty) comment in a python source; moreover, the presence or absence of a if __name__ == '__main__' clause should not change the interpretation of a soure on a syntactical level. can anyone reproduce the above problem, and/or comment on the phenomenon? cheers

• Connecting two Windows XP with MSMQ

  - by NealWalters

  This question is a cross between a developer and a server setup question. I asked on Serverfault but no answer yet. As a developer, I need to setup a test to see how MSMQ works between two machines, and I'm unclear what to do. I will use C# or BizTalk to do the read/write to/from the queues. I have MSMQ installed on two Windows XP computers. Can I configure them to pass messages back and forth, or do I need an MSMQ server in the middle? If I need an MSMQ server, does the normal MSMQ with Win2003 able to act as that? And then, how do I connect my Windows XP to that Windows 2003 server? Is it a) On screen admin dialog in the MSMQ plug-in to MMC, b) a config file, c) Active Directory, d) something else? Thanks, Neal Walters

• When do you learn from your mistakes?

  - by smayers81

  When are you supposed to learn from your mistakes in coding / design? Is it something you take with you to the next project or do you learn in the middle of your current one, sacrificing consistency for cleaner, more well-informed code? For example, my application can be distinctly demarcated down two lines of business -- say one side is for sales and the other is for marketing. Both are somewhat tied together, but as far as the team structure, use cases, developers, etc. the app consists of the Sales code and the Marketing Code. Now, say the Sales code went in first and while good-intentioned, made some bad mistakes. Should the Marketing Code follow suit and make the same mistakes for the sake of consistency or should Marketing architects and designers instead learn from the mistakes that Sales made and developer a cleaner codebase, even though Sales and Marketing are in the exact same system? Basically, do you learn from your mistakes while in a project or do you continue to pile crap on top of crap?

• SetSel on EN_SETFOCUS or WM_SETFOCUS doesn't work

  - by Coder

  I've ran into next mystic thing in Winapi/MFC, I have an edit box, contents of which I have to select on Tab, Lclick, Rclick, Mclick and so on. The sort of obvious path is to handle the SETFOCUS message and call SetSel(0, -1), which should select all text. But it doesn't work! What's wrong? I tried googling, everyone seems to override Lclilks or handle SetSel in parent windows, but this is wrong from encapsulation point of view, also multiple clicks (user wants to insert something in the middle of the text) will break, and so on. Why isn't my approach working, I tried like 10 different ways, tried to trap all possible focus messages, looked up info on MSDN, but nothing works as expected. Also, I need to recreate the carret on focus, which also doesn't seem to work. SETFOCUS message gets trapped alright. If I add __asm int 3, it breaks every time. It's the create carret and setsel that gets swallowed it seems.

• Drag and drop: jQuery UI or Scriptaculous?

  - by jpartogi

  Dear all, I am in the middle of the road whether to use jQuery UI or Scriptaculous for drag and drop. I am using Ruby on Rails, and Scriptaculous support in Ruby on Rails is superb with the existence of scriptaculous_helper.rb. But I have already use jQuery for the ajax and DOM manipulation. I do not mind to use scriptaculous since we can use jQuery.noConflict() in the code. I also kind of get the impression that scriptaculous drag and drop is better than jQuery UI drag and drop based on the online demos. So back to the original question, which one would you recommend as a drag and drop library and which one do you think is better than the other? Scriptaculous or jQuery UI?

• How can I resume downloads in 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. Move 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?

• DisplayObject.rotation not matching trig functions

  - by futuraprime

  I'm trying to label an animated pie chart, and I've been having a great deal of trouble getting rotated objects to line up with trigonometrically-positioned objects. So, for example, if I have a pie piece that's middle is angle theta and has been rotated n degrees in a tween, and then I try to position a label with code like this: label.x = center.x + Math.cos((theta + n)/180 * Math.PI) * radius; label.y = center.y + Math.sin((theta + n)/180 * Math.PI) * radius; the label is often not aligned with the center of the pie slice. Since I am also zooming in to the pie chart a great deal, the error becomes significant enough that it occasionally causes the label to miss the pie slice altogether. The error seems relatively unpredictable, and it looks a great deal like a rounding error, but I don't see any obvious rounding going on (the trig functions evaluate to ten or so decimal places, which should be more than enough here). How can I get these labels to position correctly?

• Renaming and Moving Files in Bash or Perl

  - by Katie

  HI, I'm completely new to Bash and StackOverflow. I need to move a set of files (all contained in the same folder) to a target folder where files with the same name could already exist. In case a specific file exists, I need to rename the file before moving it, by appending for example an incremental integer to the file name. The extensions should be preserved (in other words, that appended incremental integer should go before the extension). The file names could contain dots in the middle. Originally, I was thinking about comparing the two folders to have a list of the existing files (I did this with "comm"), but then I got a bit stuck. I think I'm just trying to do things in the most complicated possible way. Any hint to do this in the "bash way"? It's OK if it is done in a script other than bash script.

• How can I handle template dependencies in Template Toolkit?

  - by Smack my batch up

  My static web pages are built from a huge bunch of templates which are inter-included using Template Toolkit's "import" and "include", so page.html looks like this: [% INCLUDE top %] [% IMPORT middle %] Then top might have even more files included. I have very many of these files, and they have to be run through to create the web pages in various languages (English, French, etc., not computer languages). This is a very complicated process and when one file is updated I would like to be able to automatically remake only the necessary files, using a makefile or something similar. Are there any tools like makedepend for C files which can parse template toolkit templates and create a dependency list for use in a makefile? Or are there better ways to automate this process?

• Convert IDispatch* to a string?

  - by Rob

  I am converting an old VB COM object (which I didn't write) to C++ using ATL. One of the methods, according to the IDL, takes an IDispatch* as a parameter and the documentation and samples for this method claim that you can pass either a string (which is the progid of an object that will be created and used by the control) or an IDispatch* to an object that has already been created. How on earth do I implement this in ATL? For example, the IDL: [id(1)] HRESULT Test(IDispatch* obj); The samples (which are all JScript): obj.Test("foo.bar"); or var someObject = new ActiveXObject("foo.bar"); obj.Test(someObject); To make matters even more bizarre the actual VB code that implements this method actually declares the 'obj' parameter as a string! However, it all seems to work. Can you even pass a string to a COM method that takes an IDispatch*? If so, can I determine that the IDispatch* is actually a string in my C++ ATL code? Even better, if it's an IDispatch that implements a specific interface I will want to call methods on it, or instantiate an object if it's a string. Any ideas welcome!

• PHP set timeout for script, set_time_limit not working

  - by tehalive

  I have a command-line PHP script that runs a wget request using each member of an array with foreach. This wget request can sometimes take a long time so I want to be able to set a timeout for killing the script if it goes past 15 seconds for example. I have PHP safemode disabled and tried set_time_limit(15) early in the script, however it continues indefinitely. I've given up troubleshooting set_time_limit() and was trying to find other ways to kill the script after 15 seconds of execution. However, I'm not sure if it's possible to check the time a script has been running while it's in the middle of a wget request at the same time (a do while loop did not work). Thanks for any tips!

• Fit <TD> height to page

  - by ssg

  Consider a table with three rows with heights 10, *, 10. I'd like the middle cell to be high enough to fit to the page vertically. Unfortunately "height:100%" doesn't work at table, tr, or td level, possibly due to standards. Even if it happens to work, I don't want 100%, I want 100% of clientHeight-20px :) I can always write script to calculate remaining clientHeight but I wonder if it can be achieved in HTML/CSS standards. NOTE: I'm using table just for layout, if there are other ways to lay them down in a better way I'm ok with those approaches too.

• fixed width bash prompt

  - by seaofclouds

  I'd like to set my bash prompt to a fixed width, and make up the difference in space before the $, so whether long or short, my prompt remains the same width: [name@host] ~/Directory/Dir...Another/LastDir $ [name@host] ~/Directory(branch) $ Currently, in a short directory path my prompt looks something like this: [name@host] ~/Directory(branch) $ a deeper directory path looks like this: [name@host] ~/Directory/Dir...Another/LastDir $ You can see I've truncated the PWD in the middle so I can see where the path begins, and where it ends. I'd like to make up the difference before the $. Here is my current prompt: # keep working directory to 30 chars, center tuncated prompt_pwd() { local pwd_symbol="..." local pwd_length=30 newPWD="${PWD/#$HOME/~}" [ ${#newPWD} -gt ${pwd_length} ] && newPWD=${newPWD:0:12}${pwd_symbol}${newPWD:${#newPWD}-15} } # set prompt prompt_color() { PROMPT_COMMAND='prompt_pwd;history -a;title_git' PS1="${WHITEONMAGENTA}[\u@\h]${MAGENTA} \w\$(parse_git_branch) ${MAGENTABOLD}\$${PS_CLEAR} " PS1=${PS1//\\w/\$\{newPWD\}} PS2="${WHITEONTEAL}>${PS_CLEAR} " } In my search, I found A Prompt the Width of Your Term which does do some fill, but couldn't get it working for this particular prompt.
