• How to find the right balance between "quick & dirty" and "nice & general" code?

  - by Frank

  This is not a direct programming question, but a little help from the programming community would be appreciated. I am suffering from an overgeneralization disease. I can't stop spending valuable time with making my code most general and abstract. I could also call it the toolkit/library disease. I tend to turn every programming task into a general problem and try to "write a toolkit", that would work for many similar problems. I know it's a good thing in general, if there is enough time, but sometimes I should be writing a quick prototype and just can't seem to write the quick and dirty code that just works for the special case. I often get excited about an idea that makes the code more general and user-configurable and understimate the time it takes to actually implement it that way. Does anyone else have this experience? How can I force myself to find the right balance between "quick hack" and "nice solution"?

• When does the .NET runtime hold a reference count > 1 for COM objects?

  - by Wim Coenen

  Until recently, I believed that the .NET runtime only increases the reference count of COM objects by 1 when creating a runtime-callable wrapper, and that only one such runtime-callable wrapper is created for any given COM object. If I'm not mistaken, the above implies that Marshal.FinalReleaseComObject and Marshal.ReleaseComObject do the same thing in practice. However, today I was writing some tests to verify that COM objects are properly released by my code. I do this by invoking the supposedly released object and checking for the expected InvalidComObjectException. It turns out that there are cases where the exception is thrown after a FinalReleaseComObject, but not after a ReleaseComObject. Does this mean that the .NET 2.0 runtime can hold more than one reference to a COM object? If so, when does it do this?

• PDF form submission

  - by Jeff

  I have a PDF form (made in Acrobat) that has button to submit via HTTP. What I want to do it have a PHP script that will take the PDF form and e-mail it to me via attachment. What I don't want: --PDF Submit via e-mail button. This requires webmail users to save the pdf and attach it, and is just too confusing for most users. I want one-click and done. --Submit via mailto:[email protected]. Does the same thing as above. If there's a pdf on the server, I know how to use PHP's mail() function to e-mail it to someone. What I don't know how to do is process the PDF once someone hits Submit within the PDF. Does that make sense? Thanks, Jeff

• How to overcome drawbacks and enjoy the job of a software tester?

  - by mgj

  Dear all, One notion that has been prevalent mostly as rumours for many aspiring programmers is that the testing phase of the SDLC(Software Development Life Cycle) is not that challenging and interesting as one's job as a tester after a period of time becomes monotonous because a person does the same thing repeatedly over and over again. Boredom is a very important issue a software tester has to deal with. With regard to this I have the following questions: How can one overcome this in their day to day activities of their job as a software tester? What are the possible new avenues a tester can explore on a general note in a s/w co. ? Could you also please highlight what challenge's a tester could also face in real life situations.Something that would make their job also interesting and fun-filled. Thanks..:)

• Account verification Yelp style, how is it more "secure" than traditional verification?

  - by Chad

  For business owners to "take control" of their business page on Yelp, they register for it. The Yelp system performs a telephone call-back. From watching to the video here, it sounds like a telephone version of what we all typically do - e-mail check. For e-mail check, it basically goes like this: User registers verify e-mail sent they click link inside verify e-mail site verifies Here's Yelp's: User registers verify screen shown with code Yelp calls user user enters code site verifies It's essentially the same thing, via phone. Is there any reason you can see why this method is better than the e-mail method?

• What are some methods to debug Javascript inside of a UIWebView?

  - by bpapa

  I'm trying to figure out why something with Javascript isn't working inside of a UIWebView. To my knowledge, there is no way to set a breakpoint inside of XCode for a js file. No problemo, I'll just go back to 2004 and use alert statemen-- oh wait they don't seem to work inside of a UIWebView either! The only thing I could think of is by exporting my HTML And JS files to my desktop and then just doing my debugging inside of Safari. And that works! But of course, the bug I'm fighting with in the UIWebView doesn't occur in Safari. Are there any other ways for debugging inside of a UIWebView, or any tricks that I can use akin to using the old-school alert method?

• CA1034: Nested types should not be visible

  - by George

  Here's an explanation of the rule that that I am trying to understand. Here's the simplified code that the Code Analyzer was complaining about: Public Class CustomerSpeed Public Enum ProfitTypeEnum As Integer NotSpecified = 0 FlatAmount = 1 PercentOfProfit = 2 End Enum Private _ProfitTypeEnum As ProfitTypeEnum Public Sub New(ByVal profitType As ProfitTypeEnum) _ProfitTypeEnum = profitType End Sub End Class If the enum pertains only to the class, why is it a bad thing to make it a contained type within the class? Seems neater to me... Does anyone know what is meant by the following line?: Nested types include the notion of member accessibility, which some programmers do not understand clearly Using Namespaces to group the Class and Enum doesn't seem like a useful way to resolve this warning, since I would like both the enum to belong to the same parent level as the class name.

• mpicc hangs when called from makefile; runs fine as single command

  - by user2518579

  i'm trying to compile WRF (doubt that's relevant) and am having a problem where mpicc will hang when run w/ the compile script. icc and mpif90 have no issues. the compile script is executed w/ #!/bin/csh -f just to be verbose, here's an example. i run the script and get here make[3]: Entering directory `/home/jason/wrf/wrf3.5/external/RSL_LITE' mpicc -DMPI2_SUPPORT -DMPI2_THREAD_SUPPORT -DFSEEKO64_OK -w -O3 -DDM_PARALLEL -DMAX_HISTORY=25 -DNMM_CORE=0 -c rsl_bcast.c and hang. so then i run that line by itself jason@server:~/wrf/wrf3.5$ cd /home/jason/wrf/wrf3.5/external/RSL_LITE jason@server:wrf3.5/external/RSL_LITE$ mpicc -DMPI2_SUPPORT -DMPI2_THREAD_SUPPORT -DFSEEKO64_OK -w -O3 -DDM_PARALLEL -DMAX_HISTORY=25 -DNMM_CORE=0 -c rsl_bcast.c jason@server:wrf3.5/external/RSL_LITE$ compiles instantly. starting the compile script again does the exact same thing but on the next file. i have no idea what to do, and this is basically impossible to google for.

• What sense does asynchronous IO make if the thread is blocked anyway (see example)

  - by codymanix

  Hello, I found an example for async ftp upload on msdn which does the following (snippet): // Asynchronously get the stream for the file contents. request.BeginGetRequestStream( new AsyncCallback (EndGetStreamCallback), state ); // Block the current thread until all operations are complete. waitObject.WaitOne(); The thing what I do not understand here is, which sense does asynchronous IO make if the thread is blocked anyway with an explicit waithandle. I always thought the advantage of asynchronous IO was that the user/programm does not have to wait.

• Cost of using ASP.NET

  - by Mackristo

  One thing that I keep hearing in reference to ASP.NET and MSFT technologies is that they cost money to use. Often when they are being compared to open source languages someone will mention that one factor in favor of open source is that it's free (to an extent). My question is, when does ASP.NET actually cost money to use in terms of using the proprietary technology? Understandably there are the hosting fees, but I'm curious about the fees outside of these hosting fees. I'm especially curious about this as it relates one-person smaller-site development (non-team/large enterprise). Any help is appreciated. (edits) Some excellent answers. Much appreciated The projects that I'm looking to use the technologies for would be personal sites and very small business sites (1 or 2). The intent would of course be that these projects get much bigger. It seems that for commercial production, fees will apply. What about just basic dynamic "shared hosting" sites that provide information?

• iPhone - stdint.h file not found!

  - by Mike

  I am dealing with a project designed for iPhone OS 2.0 and I am intending to keep compatibility with this version while offering new OS 3.x functionality. When I set the base SDK to iPhone OS 3.1.3 and Target OS for 2.0, Xcode gives me this error during compilation. 'stdint.h' file not found /Developer/usr/lib/clang/1.0.1/include/stdint.h:32:16: fatal error: 'stdint.h' file not found The strange thing is that the file is there, on the path it says it is not. if I set the target OS for 3.x the problem vanishes. how to solver that? thanks for any help.

• Eclipse crashes during SVN merges

  - by Wing C. Chen

  I am currently using Eclipse Version: 3.5.1. It works perfectly in normal conditions, even with the SVN plugin, the faulty component that I am about to talk about now. The thing is that whenever I am conducting a merge, eclipse shuts down. It just crashes without even leaving an error message or anything else. It happens too often so that I can hardly normally. I am now using RapidSVN for merges. However, I would still like to know if there is any way to improve my eclipse condition.

• Unix users and permissions and how they interact with web files.

  - by Columbo

  Hello, When you issue the command ls in Linux you get this sort of thing: drwxr--r-- 1 fred editors 4096 drafts -rw-r--r-- 1 fred editors 30405 file1.php -r-xr-xr-x 1 fred fred 8460 file2.php I know that the rwxrwxrwx are the read, write and execute permissions for the current user. And I think I know that 'fred' is the user who owns the file. So I assume fred can write to file1 but no one else can. But what is the extra bit 'editors' and what is the difference between file1 and file2 with respect to one having an ownership of 'fred editors' and the other 'fred fred'? Also if a web user connects to one of the files, what is their user name and where is this decided? If the server decided that user connecting from the web was going to be fred, does this mean any web user could write to file1? Any information welcomed, I am resaerching this but just getting confused. Thanks

• JSP tag lifecycle

  - by mkoryak

  i just introduced a bug into my code because i seem to have misunderstood the jsp tag lifecycle. The tag worked like this before the bug: i pass the tag some collection as an attribute, and it displays it as a table. The collection was passed into the JSP from the controller. after the bug: a removed the attribute which set the collection. instead, in the tag i check if the collection is null, and then grab it by name from the request (using a naming convention). the thing that i didnt expect: after the collection was initially set in the tag, it would never become null on subsequent executions! it was still defined as an non-requred attribute in the TLD. I expected the tag to not hold on to previous values between executions.

• Databound Checkbox list with textboxes in a webform

  - by zSysop

  Hi all, I'm having trouble coming up with a solution for the following problem and i was wondering if someone here would help me out. I need to pull a list of supplies from a db table and list them along with two textboxes (one for quantity, and another for manufacturer) so the list would look something like this. checkbox for supply 1 | Quantity | Manufacturer checkbox for supply 2 | Quantity | Manufacturer .. I also need to store all of the checked items in a db table. I'm not sure how i should go about doing this. I've heard some talk about a repeater control being useful but i've not come across any examples that do this type of thing. Thanks in advance

• Can I have Visual Studio IDE auto-comple brackets?

  - by Alex K

  Suppose I have a line of code that starts like the following: Func1(Func2(Func3 Is it possible to set up Visual Studio (2005, 2008, 2010) IDE, so that when I hit ';' it will auto-complete all the brackets. I am only interested in brackets, nothing fancier. It doesn't have to be ';' key, it can be another key that auto-completes both brackets and ';'. This is a tiny thing that pops-up time and time again, and I've always wondered if I had to live with it. Thanks.

• Why do Programmers Love/Hate Objective-C?

  - by Genericrich

  So I have noticed that there is a lot of animosity towards Objective-C among programmers. What's your take? Is it a vendor lock-in thing against Apple? General antipathy towards Apple? The syntax? What's your view on this? With the advent of the iPhone SDK, Obj-C has gotten a lot more attention lately, and I am curious what people on SO's opinions are. I personally fought the syntax at first but have gotten more and more used to it now. I really like the named arguments. I have some pet peeves with how things are done in Obj-C vs other languages, but I will refrain from comment on them here.

• Preserving text formatting for dynamic website

  - by Mohit

  Hello Folks, I am facing a problem while creating a dynamic website. I am building it for some pharma company, which have many products. The problem is, every product have different sections of description, and have to be formatted differently. I wanted to store all the product descriptions in the database, but at the same time preserve the formatting of each description. I also plan to provide an admin interface, where they could edit the product information themselves. I could use Joomla or any other CMS for that purpose, but i wanted to know if i want to build such a system of my own, where i could format the text in an editor and them save that thing into database and when i retrieve it, i get the same formatting. How could i do this? Also i wanted to do this in PHP. Thanks -- Mohit
