• Single developer, project organization

  - by poke

  I am looking for a good (and free) way to organize some of my personal projects. I am saying "organize" because I'm not sure, if the standard project management software solutions are exactly what I am looking for and especially something what I, as a single developer, need. In general, I just want to keep my progress of my projects organized in some way. I would like to be able to keep track of milestones and split those into multiple smaller tasks, so I can keep track of my progress. So some task/issue based system would probably be good, especially as I also want to keep track of issues/bugs with specific versions (although I alone will create those issues). I am and will be the only developer on those projects, so it doesn't matter if the software is offline or online, and I also don't need any collaboration features (like commenting on things, or assigning tasks to other developers etc). But if there is a good software that fits my needs, and in addition it has those things, I don't really care. After all it's easy enough to not use available features. Many online solutions also offer integrated code hosting. I am using git internally, but I don't plan to push any of the code, so such a feature is not needed either. In case of online solutions however I would like the projects to be closed to the public (some of the online utilities only offer open source projects for free and require payments for private projects). I have looked at some project management solutions already, I also read some similar questions here on SO. But given that I'm a single developer, my focus is probably a bit different as when others ask for a huge distributed software that supports many developers and different collaboration features. Some standard answers such as Trac (which also only supports one project), Redmine and FogBUGZ look interesting, but are a bit off my interest (although you may change my mind on that :P). Currently, I'm looking at Indefero which doesn't look too bad. But what do you think?

• Port Win32 DLL hook to Linux

  - by peachykeen

  I have a program (NWShader) which hooks into a second program's OpenGL calls (NWN) to do post-processing effects and whatnot. NWShader was originally built for Windows, generally modern versions (win32), and uses both DLL exports (to get Windows to load it and grab some OpenGL functions) and Detours (to hook into other functions). I'm using the trick where Win will look in the current directory for any DLLs before checking the sysdir, so it loads mine. I have on DLL that redirects with this method: #pragma comment(linker, "/export:oldFunc=nwshader.newFunc) To send them to a different named function in my own DLL. I then do any processing and call the original function from the system DLL. I need to port NWShader to Linux (NWN exists in both flavors). As far as I can tell, what I need to make is a shared library (.so file). If this is preloaded before the NWN executable (I found a shell script to handle this), my functions will be called. The only problem is I need to call the original function (I would use various DLL dynamic loading methods for this, I think) and need to be able to do Detour-like hooking of internal functions. At the moment I'm building on Ubuntu 9.10 x64 (with the 32-bit compiler flags). I haven't been able to find much on Google to help with this, but I don't know exactly what the *nix community refers to it as. I can code C++, but I'm more used to Windows. Being OpenGL, the only part the needs modified to be compatible with Linux is the hooking code and the calls. Is there a simple and easy way to do this, or will it involve recreating Detours and dynamically loading the original function addresses?

• Is the Unicode prefix N still needed in SQL Compact Edition?

  - by Dave

  At least in previous versions of SQL Server, you had to prefix Unicode string constants with an "N" to make them be treated as Unicode. Thus, select foo from bar where fizz = N'buzz' (See "Server-Side Programming with Unicode" for SQL Server 2005 "from the horse's mouth" documentation.) We have an application that is using SQL Compact Edition and I am wondering if that is still necessary. From the testing I am doing, it appears to be unneeded. That is, the following SQL statements both behave identically in SQL CE, but the second one fails in SQL Server 2005: select foo from bar where foo=N'???' select foo from bar where foo='???' (I hope I'm not swearing in some language I don't know about...) I'm wondering if that is because all strings are treated as Unicode in SQL CE, or if perhaps the default code page is now Unicode-aware. If anyone has seen any official documentation, either yea or nay, I'd appreciate it. I know I could go the safe route and just add the "N"'s, but there's a lot of code that will need changed, and if I don't need to, I don't want to! Thanks for your help!

• RichEdit VCL and URLs. Workarounds for OnPaint Issues.

  - by HX_unbanned

  So, issue is with the thing Delphi progies scare to death - Rich Edit in Windows ( XP and pre-XP versions ). Situation: I have added EM_AUTOURLDETECTION in OnCreate of form. Target - RichEdit1. Then, I have form, that is "collapsed" after showing form. RichEdit Control is sattic, visible and enabled, but it is "hidden" because form window is collapsed. I can expand and collapse form, using Button1 and changing forms Constraints and Size properties. After first time I expand form, the URL inside RichEdit1 control is highlighted. BUT - After second, third, fourth, etc... time I Collapse and Expand form, the RichEdit1 Control does not highlight URL anymore. I have tried EM_SETTEXTMODE messages, also WM_UPDATEUISTATE, also basic WM_TEXT message - no luck. It sems like this merssage really works ( enables detection ) while sending keyboard strokes ( virtual keycodes ), but not when text has been modified. Also - I am thinking to rewrite code to make RichEdit Control dynamic. Would this fix the problem? Maybe solution is to override OnPaint / OnDraw method to avoid highlight ( formatting ) losing when collapsing or expanding form? Weird is that my Embarcadero Documentation says this function must work in any moment text has been modified. Why it does not work? Any help appreciated. I am making this Community Wiki because this is common problem and togewther we cam find solution, right? :) Also - follow-ups and related Question: http://stackoverflow.com/questions/738694/override-onpaint http://stackoverflow.com/questions/478071/how-to-autodetect-urls-in-richedit-2-0 http://www.vbforums.com/archive/index.php/t-59959.html

• Celery tasks not works with gevent

  When i use celery + gevent for tasks that uses subprocess module i'm getting following stacktrace: Traceback (most recent call last): File "/home/venv/admin/lib/python2.7/site-packages/celery/task/trace.py", line 228, in trace_task R = retval = fun(*args, **kwargs) File "/home/venv/admin/lib/python2.7/site-packages/celery/task/trace.py", line 415, in __protected_call__ return self.run(*args, **kwargs) File "/home/webapp/admin/webadmin/apps/loggingquarantine/tasks.py", line 107, in release_mail_task res = call_external_script(popen_obj.communicate) File "/home/webapp/admin/webadmin/apps/core/helpers.py", line 42, in call_external_script return func_to_call(*args, **kwargs) File "/usr/lib64/python2.7/subprocess.py", line 740, in communicate return self._communicate(input) File "/usr/lib64/python2.7/subprocess.py", line 1257, in _communicate stdout, stderr = self._communicate_with_poll(input) File "/usr/lib64/python2.7/subprocess.py", line 1287, in _communicate_with_poll poller = select.poll() AttributeError: 'module' object has no attribute 'poll' My manage.py looks following (doing monkeypatch there): #!/usr/bin/env python from gevent import monkey import sys import os if __name__ == "__main__": if not 'celery' in sys.argv: monkey.patch_all() os.environ.setdefault("DJANGO_SETTINGS_MODULE", "webadmin.settings") from django.core.management import execute_from_command_line sys.path.append(".") execute_from_command_line(sys.argv) Is there a reason why celery tasks act like it wasn't patched properly? p.s. strange thing that my local setup on Macos works fine while i getting such exceptions under Centos (all package versions are the same, init and config scripts too)

• Need advice on comparing the performance of 2 equivalent linq to sql queries

  - by uvita

  I am working on tool to optimize linq to sql queries. Basically it intercepts the linq execution pipeline and makes some optimizations like for example removing a redundant join from a query. Of course, there is an overhead in the execution time before the query gets executed in the dbms, but then, the query should be processed faster. I don't want to use a sql profiler because I know that the generated query will be perform better in the dbms than the original one, I am looking for a correct way of measuring the global time between the creation of the query in linq and the end of its execution. Currently, I am using the Stopwatch class and my code looks something like this: var sw = new Stopwatch(); sw.Start(); const int amount = 100; for (var i = 0; i < amount; i++) { ExecuteNonOptimizedQuery(); } sw.Stop(); Console.Writeline("Executing the query {2} times took: {0}ms. On average, each query took: {1}ms", sw.ElapsedMilliseconds, sw.ElapsedMilliseconds / amount, amount); Basically the ExecutenNonOptimizedQuery() method creates a new DataContext, creates a query and then iterates over the results. I did this for both versions of the query, the normal one and the optimized one. I took the idea from this post from Frans Bouma. Is there any other approach/considerations I should take? Thanks in advance!

• Convert pre-IEEE-574 C++ floating-point numbers to/from C#

  - by Richard Kucia

  Before .Net, before math coprocessors, before IEEE-574, Microsoft defined a bit pattern for floating-point numbers. Old versions of the C++ compiler happily used that definition. I am writing a C# app that needs to read/write such floating-point numbers in a file. How can I do the conversions between the 2 bit formats? I need conversion methods in both directions. This app is going to run in a PocketPC/WinCE environment. Changing the structure of the file is out-of-scope for this project. Is there a C++ compiler option that instructs it to use the old FP format? That would be ideal. I could then exchange data between the C# code and C++ code by using a null-terminated text string, and the C++ methods would be simple wrappers around sprintf and atof functions. At the very least, I'm hoping someone can reply with the bit definitions for the old FP format, so I can put together a low-level bit manipulation algorithm if necessary. Thanks.

• Please help me with a Git workflow

  - by aaron carlino

  I'm an SVN user hoping to move to Git. I've been reading documentation and tutorials all day, and I still have unanswered questions. I don't know if this workflow will make sense, but here's my situation, and what I would like to get out of my workflow: Multiple developers, all developing locally on their work stations 3 versions of the website: Dev, Staging, Production Here's my dream: A developer works locally on his own branch, say "developer1", tests on his local machine, and commits his changes. Another developer can pull down those changes into his own branch. Merge developer1 - developer2. When the work is ready to be seen by the public, I'd like to be able to "push" to Dev, Staging, or Production. git push origin staging or maybe.. git merge developer1 staging I'm not sure. Like I said, I'm still new to it. Here are my main questions: -Do my websites (Dev, Staging, Production) have to be repositories? And do they have to be "bare" in order to be the recipients of new changes? -Do I want one repository or many, with several branches? -Does this even make sense, or am I on the wrong path? I've read a lot of tutorials, so I'm really hoping someone can just help me out with my specific situation. Thanks so much!

• How to maintain base files for development environment central while allowing people to change their

  - by Ittai

  Hi, what I'd like to do is have files in a central location so that when I add people to my development team they can see the base version of these files but meanwhile have the ability for the rest of the team to work with their own local version. I know I can just put the files in source-control (we use Tortoiese-SVN) and have my team change the local versions but I'd rather not as the exclamation mark signaling the file has been changed and needs to be committed, quite frankly, irritates me greatly. I'll give two examples of what I mean: We use quite a few build.xml files which relate to a single properties files which contains many definitions. Some of them can be different between team-members (mainly temporary working directories) and I'd like a new team-member to have the ability to get the properties file with the base config but change it if they wish. Have the eclipse settings file in the SVN so that when a new team-member joins they can just retrieve the files from the server and have a base system running. If they wish they will be able to change some of these settings. Thanks, Ittai

• PHP import functions

  - by ninuhadida

  Hi, I'm trying to find the best pragmatic approach to import functions on the fly... let me explain. Say I have a directory called functions which has these files: array_select.func.php stat_mediam.func.php stat_mean.func.php ..... I would like to: load each individual file (which has a function defined inside) and use it just like an internal php function.. such as array_pop(), array_shift(), etc. Once I stumbled on a tutorial (which I can't find again now) that compiled user defined functions as part of a PHP installation.. Although that's not a very good solution because on shared/reseller hosting you can't recompile the PHP installation. I don't want to have conflicts with future versions of PHP / other extensions, i.e. if a function named X by me, is suddenly part of the internal php functions (even though it might not have the same functionality per se) I don't want PHP to throw a fatal error because of this and fail miserably. So the best method that I can think of is to check if a function is defined, using function_exists(), if so throw a notice so that it's easy to track in the log files, otherwise define the function. However that will probably translate to having a lot of include/require statement in other files where I need such a function, which I don't really like. Or possibly, read the directory and loop over each *.func.php file and include_once. Though I find this a bit ugly. The question is, have you ever stumbled upon some source code which handled such a case? How was it implemented? Did you ever do something similar? I need as much ideas as possible! :)

• How to Make a DVCS Completely Interoperable with Subversion?

  - by David M

  What architectural changes would a DVCS need to be completely interoperable with Subversion? Many DVCSs have some kind of bidirectional interface with Subversion, but there are limitations and caveats. For instance, git-svn can create a repository that mirrors Subversion, and changes to that repo can be sent back to Subversion via 'dcommit'. But the git-svn manpage explicitly cautions against making clones of that repository, so essentially, it's a Subversion working copy that you can use git commands on. Bazaar has a bidirectional Subversion capability too, but its documentation notes that Subversion properties aren't supported at all. Here's the end that I'm pursuing. I want a Subversion repository and a DVCS repository that, in the steady state, have identical content. When something is changed on one, it's automatically mirrored to the other. Subversion users interact with the Subversion repository normally. DVCS users clone the DVCS repository, pull changes from it, and push changes back to it. Most importantly, they don't need to know that this special DVCS repository is associated with a Subversion repository. It would probably be nifty if any clone of the special repository is itself a special repository and could commit directly to Subversion, but it might be sufficient if only the special repository directly interacts with Subversion. I think that's what mostly needed is to improve the bidirectional capability so that changes to Subversion properties are translated to changes in the DVCS repository. Some changes in the DVCS repository would be translated to changes to Subversion properties. Or is the answer to create a new capability in Subversion that interacts with a DVCS repository, using the DVCS repository as just a special storage layer such as fsfs or bdb? If there's not a direct mapping between the things that Subversion and a DVCS regard as having versions, does that imply that there's always going to be some activity that cannot be recorded properly on one or the other?

• Add Ellipsis to a Path in a WinForms Program without Win32 API call (revisited)

  - by casterle

  I was searching for a way to insert an ellipsis in a C# path, and found an answer here on stackoverflow: http://tinyurl.com/y6rmdfr Using the RTM versions of VS2010 and .Net 4.0, I was unable to get the suggested method to work. I searched the 'Net and found example code that uses the same method, but it failed in the same way. You can see the string I'm trying to shorten in my code below. After calling the MeasureText method, both the input string (OriginalName) and the output string (ellipsisedName) look like this: d:\abcd\efgh\ijkl\mnop\qrst\...\test.txt\0F\GHIJ\KLMN\OPQR\STIV\WXYZ\test.txt Two problems: 1) The resulting string is narfed (the path is truncated as expected, but is followed by what looks like a C-style terminating null and a chunk of the original path). 2) My original string is changed to be identical to the output string. Am I doing something wrong? namespace WindowsFormsApplication2 { public partial class Form1 : Form { public Form1() { InitializeComponent(); string OriginalPath = @"d:\abcd\efgh\ijkl\mnop\qrst\uvwx\yzAB\CDEF\GHIJ\KLMN\OPQR\STIV\WXYZ\test.txt"; string ellipsisedPath = OriginalPath; Size proposedSize = new Size(label1.Width, label1.Height); TextRenderer.MeasureText(ellipsisedPath, label1.Font, proposedSize, TextFormatFlags.ModifyString | TextFormatFlags.PathEllipsis); } } }

• Sell me Distributed revision control

  - by ring bearer

  I know 1000s of similar topics floating around. I read at lest 5 threads here in SO But why am I still not convinced about DVCS? I have only following questions (note that I am selfishly worried only about Java projects) What is the advantage or value of committing locally? What? really? All modern IDEs allows you to keep track of your changes? and if required you can restore a particular change. Also, they have a feature to label your changes/versions at IDE level!? what if I crash my hard drive? where did my local repository go? (so how is it cool compared to checking in to a central repo?) Working offline or in an air plane. What is the big deal?In order for me to build a release with my changes, I must eventually connect to the central repository. Till then it does not matter how I track my changes locally. Ok Linus Torvalds gives his life to Git and hates everything else. Is that enough to blindly sing praises? Linus lives in a different world compared to offshore developers in my mid-sized project? Pitch me!

• How to name multiple versioned ServiceContracts in the same WCF service?

  - by Tor Hovland

  When you have to introduce a breaking change in a ServiceContract, a best practice is to keep the old one and create a new one, and use some version identifier in the namespace. If I understand this correctly, I should be able to do the following: [ServiceContract(Namespace = "http://foo.com/2010/01/14")] public interface IVersionedService { [OperationContract] string WriteGreeting(Person person); } [ServiceContract(Name = "IVersionedService", Namespace = "http://foo.com/2010/02/21")] public interface IVersionedService2 { [OperationContract(Name = "WriteGreeting")] Greeting WriteGreeting2(Person2 person); } With this I can create a service that supports both versions. This actually works, and it looks fine when testing from soapUI. However, when I create a client in Visual Studio using "Add Service Reference", VS disregards the namespaces and simply sees two interfaces with the same name. In order to differentiate them, VS adds "1" to the name of one of them. I end up with proxies called ServiceReference.VersionedServiceClient and ServiceReference.VersionedService1Client Now it's not easy for anybody to see which is the newer version. Should I give the interfaces different names? E.g IVersionedService1 IVersionedService2 or IVersionedService/2010/01/14 IVersionedService/2010/02/21 Doesn't this defeat the purpose of the namespace? Should I put them in different service classes and get a unique URL for each version?

• Python: Catching / blocking SIGINT during system call

  - by danben

  I've written a web crawler that I'd like to be able to stop via the keyboard. I don't want the program to die when I interrupt it; it needs to flush its data to disk first. I also don't want to catch KeyboardInterruptedException, because the persistent data could be in an inconsistent state. My current solution is to define a signal handler that catches SIGINT and sets a flag; each iteration of the main loop checks this flag before processing the next url. However, I've found that if the system happens to be executing socket.recv() when I send the interrupt, I get this: ^C Interrupted; stopping... // indicates my interrupt handler ran Traceback (most recent call last): File "crawler_test.py", line 154, in <module> main() ... File "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/socket.py", line 397, in readline data = recv(1) socket.error: [Errno 4] Interrupted system call and the process exits completely. Why does this happen? Is there a way I can prevent the interrupt from affecting the system call?

• Looking for fast, minimal, preferrably free disc cloning software [closed]

  - by Dave

  We have to test our application installation and functionality on many Windows operating system versions and languages (XP, Vista, Win7; English, Spanish, Portuguese, etc; 32-bit & b4-bit.) While we can do much of this in virtual machines, we have noticed that VM's sometimes hide problems, or raise false bugs. So, we need to do "bare metal" OS installation for much of our testing. I have been using Acronis True Image for the past year, and am not impressed. It often gives random errors which require a reboot, and is really slow. For example, when trying to restore an image, it goes through a "Locking partition" cycle about three times (once after you click OK on each step of the wizard), each of which can take 5 minutes to complete. This all happens BEFORE it actually starts the image copy, which is sometimes quick (3-5 minutes), sometimes long (hours). The size of all of our images are roughly the same, so that is not related. So, anyway, I'm looking to switch to something else: I only need very basic functionality--just creating images of entire discs, and then restoring those images onto the exact same hard drive at a later date. That's it. I'm not opposed to paying for a good piece of software, but if there is something free out there that does the job well, that would be a preference. My OS on which the imaging software would run is Windows Vista, but a bootable media (into a Linux flavor) would be fine also, as long as its quick to use and reliable. Recommendations? (Also, moderators, if this should be a CW, I'll be happy to mark it as such; unclear about the rules there.)

• C Run-Time library part 2

  - by b-gen-jack-o-neill

  Hi, I was suggested when I have some further questions on my older ones, to create newer Question and reffer to old one. So, this is the original question: What is the C runtime library? OK, from your answers, I now get thet statically linked libraries are Microsoft implementation of C standart functions. Now: If I get it right, the scheme would be as follow: I want to use printf(), so I must include which just tels compiler there us functio printf() with these parameters. Now, when I compile code, becouse printf() is defined in C Standart Library, and becouse Microsoft decided to name it C Run Time library, it gets automatically statically linked from libcmt.lib (if libcmt.lib is set in compiler) at compile time. I ask, becouse on wikipedia, in article about runtime library there is that runtime library is linked in runtime, but .lib files are linked at compile time, am I right? Now, what confuses me. There is .dll version of C standart library. But I thought that to link .dll file, you must actually call winapi program to load that library. So, how can be these functions dynamically linked, if there is no static library to provide code to tell Windows to load desired functions from dll? And really last question on this subject - are C Standart library functions also calls to winapi even they are not .dll files like more advanced WinAPI functions? I mean, in the end to access framebuffer and print something you must tell Windows to do it, since OS cannot let you directly manipulate HW. I think of it like the OS must be written to support all C standart library functions same way across similiar versions, since they are statically linked, and can differently support more complex WinAPI calls becouse new version of OS can have adjustements in the .dll file.

• Which version of Grady Booch's OOA/D book should I buy?

  - by jackj

  Grady Booch's "Object-Oriented Analysis and Design with Applications" is available brand new in both the 2nd edition (1993) and the 3rd edition (2007), while many used copies of both editions are available. Here are my concerns: 1) The 2nd edition uses C++: given that I just finished reading my first two C++ books (Accelerated C++ and C++ Primer) I guess practical tips can only help, so the 2nd edition is probably best (I think the 3rd edition has absolutely no code). On the other hand, the C++ books I read insist on the importance of using standard C++, whereas Booch's 2nd edition was published before the 1998 standard. 2) The 2nd edition is shorter (608 pages vs. 720) so, I guess, it will be slightly easier to get through. 3) The 3rd edition uses UML 2.0, whereas the 2nd edition is pre-UML. Some reviews say that the notation in the 2nd edition is close enough to UML, so it doesn't matter, but I don't know if I should be worrying about this or not. 4) The 2nd edition is available in good-shape used copies for considerably less than what the 3rd one goes for. Given all the above factors, do you think I should buy the 2nd or the 3rd edition? Recommendations on other books are also welcome but I would prefer it if whoever answers has read at least one of the versions of Booch's book (preferably both!). I have already bought but not read GoF and Riel's books. I also know that I should practice a lot with real-life code. Thanks.

• How to update application files using patching?

  - by Marek

  I am not interested in any auto update solution, such as ClickOnce or the MS Updater Block. For anyone feeling the urge to ask why not: I am already using these and there is nothing wrong with them, I would just like to learn about any efficient alternatives. I would like to publish patches = small differences that will modify existing files of the deployment with the smallest possible delta. Not only code needs to be patched, but also resource files. Patching the running code can be accomplished by maintaining two separate synchronized copies of the deployment (no on the fly changes to the running executable are required). The application itself can be xcopy deployed (to avoid MSI auto-correcting the modified files or breaking ClickOnce signatures). I would like to learn how to handle different versions of patches (e.g. there is a patch issued that fixes one error and later another patch that fixes another error (in the same file) - users may have any combination of these and there comes a third patch - in text files, this may be easy to implement, but how about executable files? (native Win32 code vs. .NET, any difference?) If the first problem is too hard to solve or unsolvable for executables, I would like to at least learn if there is a solution that implements simple patching with serial revisions - in order to install revision 5, user must have all previous revisions installed to ensure validity of the deployment. Are there any existing solutions to accomplish this? NOTE: There are a few questions on SO that may seem like duplicates, but none with a good answer. This question is about the Windows platform, preferably .NET.

• How do you fix issues with the debugger for the Android plug-in for Eclipse not attaching?

  - by user279112

  I have been trying to program something for the Android mobile phone, using Eclipse and the Android plug-in for that IDE, and my debugger used to attach just fine. But then it has suddenly started having consistent issues attaching. I just get that message about how the process is waiting for the debugger attach, and then it just won't. What determines whether the attachment glitches so seems to have something to do with what the code is that I'm trying to debug, as it seems to be drastically more of an issue with some versions of my code than with others (on the same app). How do I fix this? Now before you answer, please understand that I have researched this issue already. I have found a couple of solutions that have worked with other people, but which do not work for me. One of which is setting the debuggable property in the main manifest file as true, and the other is going into Dev Tools and into some settings menu, and from there selecting the process and essentially saying to the fake phone, "Debug this process". Neither has really worked. Any other ideas? And just in case...I've run into one blasted technical issue like this after another trying to program for that stupid phone. And I'm not the only one who's having these issues; when I go online to research these issues, it is always very easy for me to find many people who have the same issues, and who are having to use the shottiest, sloppiest, most "ghetto" solutions to work around these issues. I know that many people have created good applications for that phone, but I don't see how I'm supposed to do that when the SDK and the plug-in just don't work half the time. Does anybody know how I may put all this trash behind me, once and for all? Thanks for your answers to either question!

• VS2010: Why do my custom Toolbox tabs and contained controls keep disappearing?

  - by Velika2

  This is how I expected the toolbox to work: Let's say I add a custom Tab to the Toolbox called "Ajaxtoolkit." To add controls to the new tab, I right mouse click and select "Choose Items" and browse to a file, Ajaxtoolkit.dll, that is of a particular version number. I would expect that when I save and reopen the solution, that the Ajax Toolkit custom tab would still be in my Toolbox and that it would contain the same controls that were there last time, the controls that were in the dll that I referenced when the controls were added. If I created a brand new web app, I (possibly) wouldn't expect to see the same Ajax Toolkit custom tab. However, I could perform the same steps as above and add a "Ajax Toolkit" tab and perhaps, this time, select a DIFFERENT VERSION of the tookit, and the state of the toolkit would be retained with each solution file. Another possibility would be for the original Ajaxtoolkit to be retained when the 2nd web solution is created, and perhaps, if I wanted to mix versions of the toolkit across diffreent web sites in my solution, I should start naming my custom toolkit tabs with version specific names like "Ajaxtoolkit 4.0," etc. ...But instead, the Ajaxtoolkit tab disappears when I close VS2010 and reopen it. Why? Is this desirable behavior or a bug?

• Trying to convert existing production database table columns from enum to VARCHAR (Rails)

  - by dchua

  Hi everyone, I have a problem that needs me to convert my existing live production (I've duplicated the schema on my local development box, don't worry :)) table column types from enums to a string. Background: Basically, a previous developer left my codebase in absolute shit, migration versions are extremely out of date, and apparently he never used it after a certain point of time in development and now that I'm tasked with migrating a rails 1.2.6 app to 2.3.5, I can't get the tests to run properly on 2.3.5 because my table columns have ENUM column types and they convert to :string, :limit = 0 on my schema.rb which creates the problem of an invalid default value when doing a rake db:test:prepare, like in the case of: Mysql::Error: Invalid default value for 'own_vehicle': CREATE TABLE `lifestyles` (`id` int(11) DEFAULT NULL auto_increment PRIMARY KEY, `member_id` int(11) DEFAULT 0 NOT NULL, `own_vehicle` varchar(0) DEFAULT 'Y' NOT NULL, `hobbies` text, `sports` text, `AStar_activities` text, `how_know_IRC` varchar(100), `IRC_referral` varchar(200), `IRC_others` varchar(100), `IRC_rdrive` varchar(30)) ENGINE=InnoDB I'm thinking of writing a migration task that looks through all the database tables for columns with enum and replace it with VARCHAR and I'm wondering if this is the right way to approach this problem. I'm also not very sure how to write it such that it would loop through my database tables and replace all ENUM colum_types with a VARCHAR.

• Using SHFileOperation: What errors are occuring

  - by Sascha

  Hello I am using the function SHFileOperation() to send a file to the recycling bin. And I am getting 2 errors that I do not know what they mean because with this function the error codes are not GetLastError() values. Now when the function SHFileOperation() fails the return values are 0x57 (decimal 87) & 0x2 (decimal 2). Can you help me discover the definitions of these errors (expecially when you consider with this function, the errors are not part of the GetLastError() codes). Some important information: • I am using Windows 7 (& I know that MSDN says to use IFileOperation instead of SHFileOperation but I want to make my app backwards compatable which is why I am using SHFileOperation). If the error is occuring because I am using SHFileOperation on Windows 7 what solution could I use to make this work on all versions of windows from 2000 & up? • I have debugged extensively & as far as I know my SHFILEOPSTRUCT is correct (correct flags used, .pFrom is a double-null ended string). One thing I know for sure is that my path to the file is correct (leads to a real file & it correctly formatted). • About 2/5 times the SHFileOperation() works, meaning it sends the file to the recycle bin & does not returns an error BOOL result; SHFILEOPSTRUCT fileStruct; fileStruct.hwnd = hwnd; fileStruct.wFunc = FO_DELETE; fileStruct.pFrom = dest.c_str(); fileStruct.fFlags = FOF_FILESONLY; // FOF_ALLOWUNDO fileStruct.fAnyOperationsAborted = result; // Call operation(delete file) int success = SHFileOperation( &fileStruct ); // if delete was successful if ( success != 0 ) { printf( "%s \t %X %d \n", dest.c_str(), success, success ); cout << result << endl; MessageBox( hwnd, "Failed to delete file", "Error", MB_OK|MB_ICONERROR ); return; }

• Ant fails without message at javac

  - by digitala

  I've written an Ant build.xml file which obtains a number of source files via WSDL and compiles them. These have been working on an old, now destroyed (and therefore unavailable for comparison), system but the build process isn't completing on this newer, faster system. The relevant section of the build file looks like this: <target name="compile" depends="init"> <java classname="org.apache.axis.wsdl.WSDL2Java"> <arg line="--all --server-side --skeletonDeploy --factory --wrapArrays --output src ${srcurl}" /> </java> <javac srcdir="${src}" destdir="${build}" verbose="yes" /> </target> The files are downloaded via the WSDL service successfully, however after that point Ant simply stops & returns to the commandline. Versions of the relevant apps: # java -version java version "1.6.0_14" Java(TM) SE Runtime Environment (build 1.6.0_14-b08) Java HotSpot(TM) 64-Bit Server VM (build 14.0-b16, mixed mode) # javac -version javac 1.6.0_14 # ant -version Apache Ant version 1.6.5 compiled on January 6 2007 I'm assuming that there's a problem with javac that Ant isn't passing back. Is there any way I can get some debugging information from javac? I've tried adding a <record /> tag to the target but that doesn't give any more information than running ant -v does. Any other suggestions would be great, also!
