• Solution to combine two submit buttons.. doing two different things from the same input

  - by zac

  I am trying to figure out how to combine two different forms, both require the same input but they do two different things. One form sends a request to the ecommerce platform to get the order status, and another form takes the same order number and returns a tracking code from USP or USPS. I am looking for some guidance on how I could combine these two actions.. one is currently using the POST method and the other GET. Here is an example .. so one is This one runs a validation script to confirm the order number is valid and then returns the order info if it is the second form is sending a get request to an asp file that is generating the proper tracking numbers. Can someone please point me to how I could begin to tackle this?

• How to test reliability of my own (small) embedded operating system ?

  - by TridenT

  I've written a small operating system for embedded project running on small to medium target. I added some automated unit test with a high test code coverage (95%), but the scope is only the static part. I got some code metrics as complexity and readability. I'm testing my code with a rule checker with MiSRA support, and of course fixed all warnings. I'm testing the code with a static analyzer and again fixed all warnings. What can I do now to test - and improve - the reliability of my OS ? How about the dynamic part ?

• More efficient way to find & tar millions of files

  - by Stu Thompson

  I've got a job running on my server at the command line prompt for a two days now: find data/ -name filepattern-*2009* -exec tar uf 2008.tar {} ; It is taking forever, and then some. Yes, there are millions of files in the target directory. But just running... find data/ -name filepattern-*2009* -print > filesOfInterest.txt ...takes only two hours or so. At the rate my job is running, it won't be finished for a couple of weeks.. That seems unreasonable. Is there a more efficient to do this? Maybe with a more complicated bash script? A secondary questions is "why is my current approach so slow?"

• How can I test my iPhone app on earlier than SDK 3.0 simulator, make sure it work?

  - by Cocorico

  Hi Stackers! I wrote iPhone application. Very simple! It use Cocos2D only, and all other features is very basic, no accelerometer, no camera, nothing. Just buttons and sounds. I think every iPhone can run this app (there is no limits on Cocos2D right?), but my XCode only let me use 3.0 and upwards. I want to confirm 1 thing and ask one thing: If I put "iPhone OS 2.0" in my iPhone OS Deployment Target in XCode, but my "Active SDK" in XCode still says 3.0, if I compile using this and submit to App Store, when it goes up, people who use 2.0 can still download and use the game yes? Is there way I can test in a 2.0 simulator to make sure it works? My XCode only have 3.0 and higher simulation.

• Considering modified files for rebuild

  - by harik

  I have a C++ project, I am using Bakefile for build process, Makefiles are generated for msvc, mingw, gnu etc for cross-platform support. Now the problem is that if I change any .h files (which are included in other .cpp files) and performing a rebuild does not recompile modified files. But changing any .cpp file gets recompiled. Based on modified time-stamp of any file which is included in the project I expect to consider that file for rebuild. Am I missing something which required to be added as a tag in .bkl files? Please help.

• How can I provide links to intranet files through ASP.net?

  - by PhoenixWright

  Conditions: The files must be opened outside of the window that the link to them is in. I have tried href, but when I give it an intranet link it only opens correctly if I leave out target="_blank"; if I put that in, the new window that opens doesn't receive the full link if there is a pound sign in the filepath... a direct link to the intranet address \a\b\c#c.txt would be fine with me; there is no concern about security, but I can't seem to get that to happen in a new window. It seems like this is happening when I don't create a new window, but I can't utilize the same window to open the links. Any ideas?

• unable to retract Sharepoint solutions

  - by BeraCim

  Hi all: I am having trouble retracting solutions in SharePoint 2007. I used both the retract solution button and the stsadm command in command line. The timer job was created in both instances, but it never gets run... it just sits in the timer job definition. The Status of the target just said "Retracting (scheduled at m/dd/yyyy MM:SS AM/PM)". I've waited for a long time and nothing happens. Has anyone experienced this before, and does anyone have a solution to this problem? Thanks.

• 3d / 2.5d game library for iphone and pc

  - by Aaron Qian

  I'm trying to make a 2d shooter game with 3d background. The player and enemies are essentially just quads with textures. The background will be simple 3d polygons with textures and some fog and light. Therefore, I don't need a really powerful 3d library. I tried Unity3D and Torque2D, but I don't like to use their GUI editors. I prefer to work with code. So, is there a cross platform (mainly windows and iPhone) 3d / 2.5d game library, commercial or open source? I assume it will be only limited to c, c++, and object-c due to apple's new ToS.

• Package <blah> does not exist error - NetBeans 6.8 & Windows 7

  - by BenMc

  I'm using NetBeans 6.8 on Windows 7. I upgraded from WinXP and NetBeans 6.7. Now my existing java web app project is no longer able to import/find the packages I've developed - I receive a 'Package ,blah. does not exist' and yet the packages do exist, worked fine in NetBeans 6.7 and the project still compiles and runs OK. I've tried changing the Java Platform/JDK from 1.6.0_10 back to JDK 1.5.0_22 but I still receive errors package does not exist. All other 'standard' libraries and packages are able to be imported and used OK ... eg Struts, Hibernate

• Deploying a .Net App Source Control (SVN) over 32-bit AND 64-bit dev stations

  - by Mika Jacobi

  Here is the situation : Our Dev Team has heterogeneous OS systems, scattered between 32-bit and 64-bit. This is not ideal, we are actually planning to homogenize our infrastructure, but in the meantime we have to deal with it. The issue is that when a 32-bit developer checks out a 64-bit solution on SVN, he has to manually change the target platforms all over again to get it compiled (not to mention other side problems) My question is : What clean (though temporary) solution could be addressed in such situation, permitting each developer to keep his default project/platform settings while checking out and in from SVN. I guess that -at least for the first time a project/solution is checked out, a dev still has to tweak the setting manually to compile it properly. After that, according to relevant SVN filters, it is possible to ignore some settings files (which ones, by the way?) I am open to all clever and detailed suggestions. Thanks.

• gcc options for fastest code

  - by rwallace

  I'm distributing a C++ program with a makefile for the Unix version, and I'm wondering what compiler options I should use to get the fastest possible code (it falls into the category of programs that can use all the computing power they can get and still come back for more), given that I don't know in advance what hardware, operating system or gcc version the user will have, and I want above all else to make sure it at least works correctly on every major Unix-like operating system. Thus far, I have g++ -O3 -Wno-write-strings, are there any other options I should add? On Windows, the Microsoft compiler has options for things like fast calling convention and link time code generation that are worth using, are there any equivalents on gcc? (I'm assuming it will default to 64-bit on a 64-bit platform, please correct me if that's not the case.)

• Applescript: Tell by Variable dilemma

  - by Johnny Grass

  I would like to do this: tell application "Finder" to set appName to (application file id "com.google.Chrome") as text using terms from application appName tell application appName to get URL of active tab of first window end using terms from This doesn't work because "using terms from" requires an application name as a string constant. If i substitute this line: using terms from application appName with this one using terms from application "Google Chrome" it works. However I don't want to rely on the target machine having the application named "Google Chrome". Using the bundle identifiers seems safer. Is there a better way to do this?

• Killing a script launched in a Process via os.system()

  - by L.J.

  I have a python script which launches several processes. Each process basically just calls a shell script: from multiprocessing import Process import os import logging def thread_method(n = 4): global logger command = "~/Scripts/run.sh " + str(n) + " >> /var/log/mylog.log" if (debug): logger.debug(command) os.system(command) I launch several of these threads, which are meant to run in the background. I want to have a timeout on these threads, such that if it exceeds the timeout, they are killed: t = [] for x in range(10): try: t.append(Process(target=thread_method, args=(x,) ) ) t[-1].start() except Exception as e: logger.error("Error: unable to start thread") logger.error("Error message: " + str(e)) logger.info("Waiting up to 60 seconds to allow threads to finish") t[0].join(60) for n in range(len(t)): if t[n].is_alive(): logger.info(str(n) + " is still alive after 60 seconds, forcibly terminating") t[n].terminate() The problem is that calling terminate() on the process threads isn't killing the launched run.sh script - it continues running in the background until I either force kill it from the command line, or it finishes internally. Is there a way to have terminate also kill the subshell created by os.system()?

• Why is it bad practice to use links with the javascript: "protocol"?

  - by zneak

  Hello everyone, In the 1990s, there was a fashion to put Javascript code directly into <a> href attributes, like this: <a href="javascript:alert('Hello world!')">Press me!</a> And then suddenly I stopped to see it. They were all replaced by things like: <a href="#" onclick="alert('Hello world!')">Press me!</a> For a link whose sole purpose is to trigger Javascript code, and has no real href target, why is it encouraged to use the onclick property instead of the href property?

• VB.NET Window Screen Capture (ALT+PRINTSCREEN)

  - by Steve Thomas

  Hi, I found that code somewhere and I find it quite useful but I would like to find a way to make it work so it capture only the given window target. Maybe with a processID or Window Name. Even if that window is not active. I do not want to make that window active but want to get a screen capture like if I was doing Alt+PrintScreen on it. Here is the code that works for full Screen Capture Private bmpScreenShot As Bitmap Private gfxScreenshot As Graphics bmpScreenShot = New Bitmap(Screen.PrimaryScreen.Bounds.Width, Screen.PrimaryScreen.Bounds.Height, PixelFormat.Format32bppArgb) gfxScreenshot = Graphics.FromImage(bmpScreenShot) gfxScreenshot.CopyFromScreen(Screen.PrimaryScreen.Bounds.X, Screen.PrimaryScreen.Bounds.Y, 0, 0, Screen.PrimaryScreen.Bounds.Size, CopyPixelOperation.SourceCopy) bmpScreenShot.Save(fileName, ImageFormat.Png) I use the Visual Basic 2008 Express Thank you in advance!

• How hard is it for a .NET programmer to learn Objective C and Cocoa?

  - by rsteckly

  Hi, I'm trying to build a dual platform application for a company of my own I'm trying to start at night. I have the .NET version done, but have not finished the UI part. I'm thinking of buying some 3rd party controls. If I buy these controls, however, they clearly will only work in my Windows version. I'm wondering if I should try to do the UI in GTK# and use Mono with CocoaSharp or just build the thing in MS technology and teach myself the Mac side? I'm just really unfamiliar with the Mac world and am wondering how much of a learning curve there might be. I've thought perhaps of rewriting my core logic in Ruby or Python. This why I could use the .NET version with .NET controls and presumably hook the same code up on the Mac. It's an educational app targeted at consumers. As such, it shouldn't require a lot of technical sophistication to install.

• Include a unique URL in EXE

  - by John Grey

  Hi :) I want to give users of my site the ability to upload their software/hardware configuration automatically on Windows. So I'm thinking of having an EXE file download, and somehow put in that EXE a unique URL for each user. When the data is collected, the program would just posts some JSON to that URL. How can I do it? I'm most familiar with .NET platform. Tools like this do exist, for example Blizzard uses this approach for their beta test enroll. Each user downloads a slightly different EXE. TIA

• feedback for programming newbies looking to build a social networking site?

  - by kgardnr

  my partner and i are launching a social learning platform - the requirements have been mapped out and are quite basic/intuitive. we are familiar with html/css, and have some very basic understanding of php, but we would love some feedback on whether we should tackle this ourselves or not. we've built websites, but in the past relied mostly on pre-fab code, i.e. wordpress, ning, etc. we've been looking specifically at ruby for developing the network, but i haven't delved into it fully yet. we're looking for some guidance and feedback - e.g. thoughts on ruby on rails? what's the learning curve? are we getting in over our heads? thanks in advance!

• IE downloads and installs CAB dialog popup upon every page refresh

  I have a signed cab on an aspx page. I am seeing the following inconsistent behavior. Any insights would be highly appreciated. On some machines, the cab is downloaded and installed on every page refresh. On few of those machines, the IE "install cab" dialog pops up on every page refresh, while on the others it pops up only once. Additional info: The CAB contains a .NET DLL The CAB is slightly large (around 30 MB), hence recurring download behavior is a pain Target browsers are IE6 and IE7, and the behavior is common to both!

• Heavy use of templates for mobile platforms

  - by Chris P. Bacon

  I've been flicking through the book Modern C++ Design by Andrei Alexandrescu and it seems interesting stuff. However it makes very extensive use of templates and I would like to find out if this should be avoided if using C++ for mobile platform development (Brew MP, WebOS, iOS etc.) due to size considerations. In Symbian OS C++ the standard use of templates is discouraged, the Symbian OS itself uses them but using an idiom known as thin templates where the underlying implementation is done in a C style using void* pointers with a thin template layered on top of this to achieve type safety. The reason they use this idiom as opposed to regular use of templates is specifically to avoid code bloating. So what are opinions (or facts) on the use of templates when developing applications for mobile platforms.

• jquery ui position fails with margin

  - by oliwel

  Hi, I am trying to use jQuery to position an inpage div (Context-Menu) relative to a clicked tablerow on a webpage. This works fine until I add an offset with either "left" or "margin-left" to the outer container. Using padding-left works.... The relevant code is: $('#supermenu').position({ my: "left top", at: "left top", of: $(event.target).closest('tr'), collision: "fit" }); The caller looks like: <tr onclick="getMenu(event)"><td>.... What happens: The left margin is added "twice" to the X Offset, so the Menu is not aligned to the left border of the table but somewhere right of it. The offset from the border is exactly the offset from the outer container. Anybody can shed some light? Oliver

• Odd problem with IE8 and z-index CSS property

  - by DK39

  I not been able to put one DIV over his parent DIV in Internet Explorer. With Firefox is working as suposed to. The odd part is that if I open the html file directly in IE, everything works fine.

• Missing archetype.xml in new archetype created from project.

  - by sdoca

  Hi, I am using Maven 2.2.1. and am new to Maven. I am trying to create an archetype based on an existing project. I have been using this blog post as a guide: http://blog.inflinx.com/category/m2eclipse/ Step 7 says "The next step is to verify that the generated archetype.xml (located under srcmainresourcesMETA-INFmaven (sic)) has all the files listed and they are located in the right directories." My generated archetype does not have an archetype.xml. It does have an archetype-metadata.xml file though. There aren't any errors in the output from calling archetype:create-from-project, just a couple of warnings about using platform encoding (Cp1252). Any thoughts on why this file wasn't generated? Thanks in advance!
