• Easy_install of wxpython has "setup script" error.

  - by vgm64

  I have an install of python 2.5 that fink placed in /sw/bin/. I use the easy install command sudo /sw/bin/easy_install wxPython to try to install wxpython and I get an error while trying to process wxPython-src-2.8.9.1.tab.bz2 that there is not setup script. Easy-install has worked for several other installations until this one. Any help on why it's busting now? EDIT: The error occurs before dumping back to shell prompt.

• Error in PHP soap client to .NET soap Server

  - by Gabriel

  PHP soap client in attempting to interact with a .NET soap server results in the following error: [soap:Receiver] Server was unable to process request. --- Invalid length for a Base-64 char array. $credentials = array( 'RequestorUID'=> 'xxxx', 'RequestorPassword'=> 'xxxx' ); $param = array('pmPropertyManagerID'=>'xxxx'); $client->GetPropertyStatus($credentials, $param); GetPropertyStatus take two arguments, a credentials object - which works correctly as other functions that only require credentials are executed correctly. The second argument is defineds as a string and I have attempted to input it directly as a string and base64_encoded string (error: Length of the data to decrypt is invalid), an array and an associative array both string and base64_encoded string and get the error above. Any help would be appreciated.

• Restarting Tomcat from Tomcat itself

  - by Jack

  Hello, is it possible to restart Tomcat6 by executing a JSP? This because I would like to deploy the changes of an application by doing it remotely using the webserver. The deploy script is written in bash and it checkouts the latest version from the svn, then package it as a war, then copy it in /webapps/ while adding some libs. If I execute it from a JSP (for example by using System.execute(..) will it cause problems? The fact is that the script itself is something like: /etc/init.d/tomcat6 stop # do things /etc/init.d/tomcat6 start so I don't think it would work.. is there a way to execute a stand-alone process from inside tomcat?

• Repository Pattern and Entity Framework.

  - by vitorcast

  Hi people, I want to make an implementation with repository pattern with ASP.NET MVC 2 and Entity Framework but I have had some issues in the process. First of all, I have 2 entities that has a relationship between them, like Order and Product. When I generate my dbml file it gaves me a class Order with a property that map a "ProductSet" and one class Product with a property that map wich Order that Product relates itself. So I create my Repository pattern like IReporitory with the basic CRUD operations and inside my controllers I implement the ProductRepository or OrderRepository. The problem occurs when I try to create Product and have to assign my Order on it, like ProductOne.Order = _orderRepository.Find(orderId); That operation gave me some strange behavior and I can't find out what is wrong with it. Thanks for the help.

• node.js on multi-core machines

  - by zaharpopov

  node.js looks interesting BUT... I must miss something - isn't node.js tuned only to run on a single process & thread? Then how does it scale for multi-core CPUs and multi-CPU servers? After all, it is all great to make fast as possible single-thread server, but for high loads I would want to use several CPUs. And the same goes for making applications faster - seems today the way is use multiple CPUs and parallelize the tasks. How does node.js fit into this picture? Is its idea to somehow distribute multiple instances or what?

• Python XLWT attempt to overwrite cell workaround

  - by PPTim

  Hi, Using the python module xlwt, writing to the same cell twice throws an error: Message File Name Line Position Traceback <module> S:\******** write C:\Python26\lib\site-packages\xlwt\Worksheet.py 1003 write C:\Python26\lib\site-packages\xlwt\Row.py 231 insert_cell C:\Python26\lib\site-packages\xlwt\Row.py 150 Exception: Attempt to overwrite cell: sheetname=u'Sheet 1' rowx=1 colx=12 with the code snippet def insert_cell(self, col_index, cell_obj): if col_index in self.__cells: if not self.__parent._cell_overwrite_ok: msg = "Attempt to overwrite cell: sheetname=%r rowx=%d colx=%d" \ % (self.__parent.name, self.__idx, col_index) raise Exception(msg) #row 150 prev_cell_obj = self.__cells[col_index] sst_idx = getattr(prev_cell_obj, 'sst_idx', None) if sst_idx is not None: self.__parent_wb.del_str(sst_idx) self.__cells[col_index] = cell_obj Looks like the code 'raise'es an exception which halts the entire process. Is removing the 'raise' term enough to allow for overwriting cells? I appreciate xlwt's warning, but i thought the pythonic way is to assume "we know what we're doing". I don't want to break anything else in touching the module.

• Coding Competition, language agnostic guidelines?

  - by Miau

  Hi there: I might be doing a coding competition soon, I was wondering if anyone made one and what where the guidelines/ process. I'd like to make the competition appealing to all devs, and I m trying to come up with ideas as to how. the scenario is: There is an event running and we(of the coding competition) will have a room that we can use (either to code or for questions, etc), however, ideally the task for the competition should be assignet and they should eb able to go and do other things, if they are so inclined. what i wonder is what kind of challenges to give, and most importantly, what is the criteria to "win" teaching and learning good coding standards takes a looong time, and I d like to think that if you ve been coding for longer you ll do things right and quick... but in a competition, you would be cutting corners... I would really appreciate your input on this

• C# HttpListener without using netsh to register a URI

  - by Chris T

  My application uses a small webserver to server up some files and have a web interface for administration remotely. Right now the user has to use netsh to register the URI like so netsh http add urlacl url=http://+:1233/ user=Chris-PC\Chris Which is no fun for the average user. I'd like the program to be able to listen on any port specified by the user from my program without the end-user needing to using command prompt. Is there anyway to accomplish this short of just using Process.Start and running command prompt myself?

• Modularizing web applications

  - by Matt

  Hey all, I was wondering how big companies tend to modularize components on their page. Facebook is a good example: There's a team working on Search that has its own CSS, javascript, html, etc.. There's a team working on the news feed that has its own CSS, javascript, html, etc... ... And the list goes on They cannot all be aware of what everyone is naming their div tags and whatnot, so what's the controller(?) doing to hook all these components in on the final page?? Note: This doesn't just apply to facebook - any company that has separate teams working on separate components has some logic that helps them out. EDIT: Thanks all for the responses, unfortunately I still haven't really found what I'm looking for - when you check out the source code (granted its minified), the divs have UIDs, my guess is that there is a compilation process that runs through and makes each of the components unique, renaming divs and css rules.. any ideas? Thanks all! Matt Mueller

• idioms for returning multiple values in shell scripting

  - by Wang

  Are there any idioms for returning multiple values from a bash function within a script? http://tldp.org/LDP/abs/html/assortedtips.html describes how to echo multiple values and process the results (e.g., example 35-17), but that gets tricky if some of the returned values are strings with spaces in. A more structured way to return would be to assign to global variables, like foo () { FOO_RV1="bob" FOO_RV2="bill" } foo echo "foo returned ${FOO_RV1} and ${FOO_RV2}" I realize that if I need re-entrancy in a shell script I'm probably doing it wrong, but I still feel very uncomfortable throwing global variables around just to hold return values. Is there a better way? I would prefer portability, but it's probably not a real limitation if I have to specify #!/bin/bash.

• TFS Build Automation - Web Deployment Project error

  - by gracejz

  I'm trying to build a web deployment project using TFS automated build process. When I build the project directly in Visual Studio 2008, it works fine.

• GUI and non gui difference

  - by stdcinout

  hi guys as i know we have gui and non gui application today. but remember back in the old days there were many application thats kinda like half gui half not . the applications are text based and it has no GUI like what we have now if we were to use java swing library or etc. but you could pretty much select the area that you want using keyboard shortcut . pretty much looks like vim with more features. basically it is text based but not fully gui so my question is how did they do this ? to make the text output persistent and process the data as being inputed non sequentially (non gui typically inputs data non sequentially)

• C# Windows Live Messenger Connectivity?

  - by Pcstalljr

  Hey there guys, I'm working on an IRC bot project, Trying to integrate Windows live into a bot, And have received messages sent to the channel. But the current problem is that the old messenger API that I had no longer works. And the current API i can only find information about addins (complicated for the end user to set up unless I make an installer), Or contact information. I would like my bot to be stand-alone (no messenger required) and have it log in it self, But I can not find information on the login process anywhere. Any ideas?

• XCOPY to remote server

  - by Max

  In order to improve the deployment / build process of my ASP.NET app, I would like to make a .bat that builds the current solution in release mode xcopy the files to a remote server Creating a release build via command line is easy. But how can I xcopy the files to the remote server? I think I have to map the remote destination to a network drive (?). However I could not connect to the remote server, although I have enabled file sharing for the folder on the server. Maybe the firewall is blocking the request? Which port should I open? Or is there another solution? EDIT Thanks for all the answers so far, but I probably need a step by step guide on how to set up the folder sharing on the server. I shared the folder, I opened up port 445 so that I can connect to the server but still, I cant connect from my local machine to the server in order to map the network path to a system drive.

• Configuration file 'C:\my\App.Config' is being used to configure all executables

  - by Taylor Leese

  I have a Visual Studio setup project that installs an application into the task scheduler and also installs a GUI application to manage some configuration parameters in the registry. This being the case, the setup project installs two different primary outputs (.exe's) as part of the process. I am getting the following warning when I rebuild the setup project: Configuration file 'C:\my\App.Config' is being used to configure all executables Is there any way to remove this warning? The suggested MSFT solution apears to be to use a different setup project for each .exe, but I only want the users to have to run one installer. Any suggestions?

• VS2010 MSTest CruiseControl.NET .NET 3.5

  - by Bill Campbell

  Hi, We're in the process of upgrading from VS2008 to VS2010 since it's now released. We are using CC.NET along with MSTest and want to use MS coverage tool instead of NCover. Interestingly, as I've seen others talking about as well, when you upgrade your project from VS2008 to VS2010 your Test Projects get converted to .NET 4. Nice move!! So WTF does one do with their CI environment in order to build this stuff (some projects in .net 3.5, some in .net 4 - these are different FRAMEWORKS!) LOL!!! It seems that I might need to have my CC.NET build two separate projects? - not sure about how to run the units tests from cruise with .net 4. Has anyone done this and have a snippet of their config they might share? And I thought this was going to be a simple thing. :( thanks! Bill44077

• FileSystemWatcher.WaitForChanged returns, but there is still a lock on the file

  - by SnOrfus

  I have a program that send a document to a pdf printer driver and that driver prints to a particular directory. After the print I want to attach the pdf to an e-mail (MailMessage) and send it off. Right now, I send the document to the printer (wich spawns a new process) and then call a FileSystemWatcher.WaitForChanged(WaitForChangedResult.Created) but when the object is created, it's still not done "printing" and the pdf printer still has a lock on it, throwing an error when I try to attach that file to an e-mail. I've considered a plain Thread.Sleep(2000) or whatever, but that's far less than ideal. I considered putting the attachment code in a try/catch block and looping on failure, but again, that's just bad news. I can't really think of an elegant solution.

• Cannot create multiple instances of PowerPoint

  - by Excel20

  I'm working on a project where I need to use PowerPoint from C#.net. Initially, I always created one single instance. As of today, I would like to have multiple instance running. I do that like so: Type powerpointType = Type.GetTypeFromProgID("PowerPoint.Application"); object instance1 = Activator.CreateInstance(powerpointType); object instance2 = Activator.CreateInstance(powerpointType); but when I ask for the handle of both instances, by calling hwnd = (int)powerpointType.GetProperty("HWND").GetValue(instance1, null); then I get the same handle twice. My conclusion is that the application is started just once, and the TaskManager comfirms that: Only one process. How come there is only one instance of PowerPoint running, and how can I make it work?

• Good book for THINKING in terms of algorithms?

  - by chrisgoyal

  Before you mark this is a duplicate, let me explain why this is different. Most of the books on algorithms are more of a reference. You basically have a list of algorithms at your disposal. But what happens when you need to create a new algorithm for something? These books don't teach how to think in terms of algorithms. So I'm looking for books that will teach me the thinking-process of creating algorithms. Any good suggestions?

• how to handle iframes/frames dom in the iphone uiwebview

  - by user217428

  in (void) webViewDidFinishLoad: (UIWebView*)webView I inject some javascript to handle the iframes. e.g. stringByEvaluatingJavaScriptFromString: @"try { var document = window.document.getElementsByTagName('iframe')[0].contentWindow.document.getElementsByTagName('frame'); } catch (e) { alert (e.message); }" It tells me the iframes document is undefined. Actually I have tried to print all the properties of contentWindow of iframe, but it's totally empty. I know the webViewDidFinishLoad may be called several times for each frame load. But I can never get the iframe document. I thought there should be at least once all the iframes are ready. Could someone please tell me how to get the iframe document to process the dom in the uiwebview? Thanks
