• What notes should I be taking, if any, at the beginning of a project?

  - by Justin R.

  I was recently asked by a Team Leader (not mine) if I would be willing to undertake a programming project. The members of his team are currently pre-occupied with other more important projects. I graduated college two years ago, and up until now programming has only been a hobby of mine. Recently I decided that I would like to pursue a career in software development. I accepted his offer so that I can gain some real-world experience and start building a portfolio. In about an hour I'm scheduled to meet with the Team Leader to discuss the details of what he needs. From a short e-mail exchange with him, I know that the base project is to update an existing ASP.NET form—but I also think there's more to it than that. Considering that I'd like to eventually put this project in a portfolio, what kinds of notes should I take at the meeting?

• MSAccess Change Date Value Before Validation

  - by sisdog

  In a grid I have a date/time field where I would like the user to be able to type in short-hand formats for dates and times. For example, if they type in "435p" and then focus off of the cell they get the message "The value you entered isn't valid for this field.". Instead, I want to trap a pre-validationevent and change it to "4:35pm" for them. What event can I use? I've tried: LostFocus & BeforeUpdate: too late (validation fires before event) Dirty & OnChange: too early (they haven't left the cell yet) Or is there a way to turn off the native validation rule that is checking for date formats?

• Qt: any way to automatically generate QSharedData-based structures?

  - by Eye of Hell

  Hello. Qt has a build-in supprt for creating objects with integrated reference counting via QSharedData and QSharedDataPointer. All wordks great, but for each such object i need to write a lot of code: QSharedData-based implementation class with constructor and copy constructor, object class itsef with accessor methods for each filed. For a simple structures with 5-10 fields this requires really lot of near same code. Is it some ways to automate such classes generation? Maybe it's some generators exists that take a short description and automatically generates implementation class and object class with all accessors?

• How to track IIS server performance

  - by Chris Brandsma

  I have a reoccurring issue where a customer calls up and complains that the web site is too slow. Specifically, if they are inactive for a short period of time, then go back to the site, there will be a minute-two minute delay before the user sees a response. (the standard browser is Firefox in this case) I have Perfmon up and running, the cpu utilization is usually below 20% (single proc...don't ask). The database is humming along. And I'm pulling my hair out. So, what metrics/tools do you find useful when evaluating IIS performance?

• What experience is the most valued in a programmer?

  - by Christo

  I've been coding application level software for a while now. I've had some experience with internet (server/client based) applications, but that has been fairly scant. The field doesn't scare although I know that experience can be almost be measured in gold. I see myself as a highly qualified and experienced programmer, but I also see my short comings in these fields. Does this count against me (and others like me?) and would this cut anyone from obtaining the shortlist or are there other factors which bear more weight?

• How can you pass GET values to another url in php? GET value forwarding

  - by gobackpacking

  Ok, so I'm using Jquery's AJAX function and it's having trouble passing a URL with a http address. So I'm hoping to "get" the GET values and send them to another URL — so: a local php file begin passed GET values, which in turn forwards the GET values to another url. Maybe curl is the answer? I don't know. It's got to be a very short answer I know. pseudo code: //retrieve the GET values $var retrieve [GET] //passing it to another url send get values to url ($var, url_address)

• How to use SQLiteOpenHelper without or less restrictive use of Context?

  - by Pentium10

  If you extend SQLiteOpenHelper, for the Constructor you have to use a Context. I am wondering if there is a way to leave this out, and be able to work with database tables without a Context. Or at least be least restrictive, I mean a way of project/class structure that will make history the several context passings I have to do now. As it is my application has several level of classes, chained in each other, and there are a few that connects to the database, but have no whatsoever influence on the interface, so they don't actually need the Context. Are you creating your classes in the way that you pass each time a Context to them? If not, how you do, how you reuse a Context in a short class?

• What is the best regular expression for validating email addresses?

  - by acrosman

  Over the years I have slowly developed a regular expression that validates MOST email addresses correctly, assuming they don't use an IP address as the server part. Currently the expression is: ^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,4})$ I use this in several PHP programs, and it works most of the time. However, from time to time I get contacted by someone that is having trouble with a site that uses it, and I end up having to make some adjustment (most recently I realized that I wasn't allowing 4-character TLDs). What's the best regular expression you have or have seen for validating emails? I've seen several solutions that use functions that use several shorter expressions, but I'd rather have one long complex expression in a simple function instead of several short expression in a more complex function.

• how to write T-SQL to compare and copy data?

  - by George2

  Hello everyone, I have two SQL Server 2008 Enterprise databases (on two machines), and one of the databases is master database and another database is slave database. I want to transfer update from a table in source database to a table in destination database (two tables are of the same schema, both of them are using a single column as unique primary key). The transfer rule is (in short, the rule is keeping the destination database the same as source database because of the update of the source database), if there is a new row in source database but not in destination database, insert the row in destination database; if a row not exists in source database but exists in destination database, delete the row in destination database; if a row's content (i.e. columns other than primary key columns) changes in source database, update the new content into destination database. thanks in advance, George

• How to analyse Dalvik GC behaviour?

  - by HRJ

  I am developing an application on Android. It is a long running application that continuously processes sensor data. While running the application I see a lot of GC messages in the logcat; about one every second. This is most probably because of objects being created and immediately de-referenced in a loop. How do I find which objects are being created and released immediately? All the java heap analysis tools that I have tried(*) are bothered with the counts and sizes of objects on the heap. While they are useful, I am more interested in finding out the site where temporary short-lived objects get created the most. (*) I tried jcat and Eclipse MAT. I couldn't get hat to work on the Android heap-dumps; it complained of an unsupported dump file version.

• Concatenating a Text in front of Individual Database Records with Tcl

  - by DFM

  Hello: In short, currently I am using the following code to pull records from multiple tables in a Sqlite Db and insert them in a single combobox ($SearchBar): set SrchVals1 [db eval {SELECT DISTINCT Stitle From Subcontract Order By Stitle ASC}] set SrchVals2 [db eval {... set SrchVals3 ... set SrchValsALL [concat $SrchVals1 $SrchVals2 $SrchVals3] $SearchBar configure -value $SrchValsAll For the variable "SrchVals1", I am trying to figure out a way to concatenate the text "Sub: " to each individual record in SrchVals1. For example, if SrchVals1 shows the following records in the combobox: First Title Second Title Third Title I would like to concatenate so that the records in the combobox look like this: Sub: First Title Sub: Second Title Sub: Third Title I understand that I might have to use a foreach statement; however, I am having no luck writing one that adds "Sub: " in front of each record, as opposed to one. This seems like something that should be pretty easy, but I cannot seem to figure it out. Does anyone know how I can achieve these results? Thank you, DFM

• predict location of single-line text from a UITextView

  - by William Jockusch

  Is this possible? Specifically, I have a UITextView, and the text is short enough that it will fit on a single line. I want to predict where it will appear, so that (for example) if I wanted to, I could set up a UILabel that rendered the text in exactly the same location. Once I get that figured out, what I really want to do is pick contentInset and/or contentOffset so that the text of the UITextView and the left-justified UILabel will render in the same location. But I figure the above will let me do that. EDIT: In response to a comment, the fundamental problem I am trying to get around is that UITextField does not let you set the location of the cursor. It appears a lot of people have tried to get around this without success. I need to be able to move the cursor -- inserting/deleting text there is not enough. Control cursor position in UITextField Insert string at cursor position of UITextField Moving the cursor to the beginning of UITextField iOS -- dealing with the inability to set the cursor position in a UITextField

• is it good practice to use iframe to implement header/navbar?

  - by Xah Lee

  is it good practice to use iframe to implement header/navbar? my website is basically 5 thousand pages but all static html (not using any content manager, php, etc.). am in the process to add a navbar at the top of each page. e.g. tabs, or crumbs, or any sort of header with js menu. (the exact design not decided yet) my question is, is it good practice to use a iframe for this? (so, instead have same text repeated in all 5 thousand pages, each will just have a short iframe pointing to a header file) am aware that one should reduce http request for speed, but this is ok with me. Any other problems i might have with this? SEO or any tech issue?

• Command to surround a character with spaces in vim

  - by William Becker

  I am trying to use vim properly - to aid me I've mapped my arrow keys to "" so that I am forced to use {hjlk} to move around. This is causing me a problem when I want to just surround a character with spaces, eg: "2+3" is better formatted "2 + 3" Previously I would have put my cursor over the + and typed: i[space][arrow-right][space][Esc] That's 5 presses. To do this without the arrow I seem to need to put the cursor over the + and go: i[space][Esc]lli[space][Esc] That's 8 presses. I can convert the "li" into an "a" which reduces it to 7 presses: i[space][Esc]la[space][Esc] Short of writing this into a macro is there a better way of doing it? Is there some magic vim command which will allow me to do it in less than even 5 presses - and some way to generalise it so that I can do it to entire words or symbols, eg if I want to convert 3==4 to 3 == 4?

• What is a good standard for code width?

  - by BillyONeal

  Hello everyone :) I've heard in several places that it's bad to have code that is too wide onscreen. For example: for (std::vector<EnumServiceInformation>::const_iterator currentService = services.begin(); currentService != services.end(); currentService++) However, I've heard many arguments for 80 character wide limits. I'm assuming this 80 character limit comes from the traditional command prompt, which is typically 80 characters wide. However -- most of us are working on something much better than a typical command prompt, and I feel that using an 80 character limit encourages use of variable names that are far too short and do not describe what the variable is used for. What is a reasonable limit for a new project with no existing coding width standard?

• How to migrate a codebase from one svn repo to another preserving history?

  - by chotchki

  I have a branch in a badly structured svn repo that needs to be stripped out and moved to another svn repository. (I'm trying to clean it up some). If I do an 'svn log' and not stop on copy/rename I can see all 3427 commits that I care about. Is there some way to dump the revisions out, short of writing some major scripts? I would follow the advice in this question but this branch has been moved all over the place and I would like to preserve the moves as well. Any ideas?

• Regex for zeroing in on build output text error

  - by Mike Atlas

  I'd like to quickly hone in on what failed in a build log output that is nearly 5k lines long, using Notepad++ as my editor for the file. Notepad++ has the nice ability to specify regular expressions, so I am wondering if there is a way to not match: Compile complete -- 0 errors, 0 warnings but to match, for example: Compile complete -- 1 errors, 0 warnings Compile complete -- 100 errors, 0 warnings where the match would be (1 or more) errors. If this isn't possible, I will probably just write a quick line-by-line parsing tool instead, but I was hoping someone on StackOverflow could whip out a regular expression in the same amount of time - I'm definitely not proficient enough with regular expressions to be able to write one for my needs in a short amount of time.

• Allocation Target of std::aligned_storage (stack or heap?)

  - by Zenikoder

  I've been trying to get my head around the TR1 addition known as aligned_storage. Whilst reading the following documents N2165, N3190 and N2140 I can't for the life of me see a statement where it clearly describes stack or heap nature of the memory being used. I've had a look at the implementation provided by msvc2010, boost and gcc they all provide a stack based solution centered around the use of a union. In short: Is the memory type (stack or heap) used by aligned_storage implementation defined or is it always meant to be stack based? and, What the is the specific document that defines/determines that?

• Find window handle of a ribbon button

  - by ldx

  Hi, I'm trying to do some automation of windows applications. To do whatever I want to do, I need the window handles of some controls. Before, I would accomplish this with a combination EnumWindows, EnumChildWindows and GetWindowText. But now, some newer programs no longer have toolbar with buttons on it. Instead, they have a ribbon. This didn't seem like much of a problem to me at first, but now I notice that the buttons on the ribbon don't show up in EnumChildWindows! Or at least GetWindowText does not return the same text as the one seen on the screen. So to make a long story short: Can anybody tell me how I can programatically find the handle of a button on a ribbon? Thanks. Regards, ldx
