Removing a specific XML node in TIBCO BusinessWorks

- by sangretu

I have a "global variable" XML schema in TIBCO BusinessWorks. It's simpler than it looks - basically just a single repeatable node. Image: Tibco globals. (old URL redacted) Various processes in the system can update this list. Checking to see if they are listed is easy: $GetVariable/subscriber-list/subscriber = $_processContext/ns:ProcessContext/ProcessId Adding themselves to the list is pretty easy too, using a Set Variable activity (see bottom half of image) But how can a process remove itself from the list? I'm sure there's a type of mapping I can use to filter out the node I want and let the rest through?

emacs elisp buffer not running font lock mode until opened by user

- by jacob

My problem is I am opening a buffer using (set-buffer (find-tag-noselect (current-word))) and then I try to copy some text out of that buffer. The text that I get back has only the properties (fontified nil). find-tag-noselect automatically opens the buffer found in the TAGS file but it seems it does not run the font lock mode over it. When I manually switch to this buffer after it has been opened and then run the function again when it copies the text it has all the correct text properties attached. So what do I need to do to have this buffer completely initialized so that the correct syntax highlighting will be copied in?

SyntaxError using gdata-python-client to access Google Book Search Data API

I've looked at the wiki and open issue tickets on Google Code to no avail (and this seems to me more apt to be a silly error on my end rather than a problem with the library). I'm not sure how to interpret the error message. If it matters, I'm using python 2.6.5.

git checkout master/branching question

- by danwoods

Hello all, I 'm relatively new to git and and having some problems early on. I've made several commits, but when I try to push them I get a response that says everything is up-to-date. I feel like my problem is the same on listed in this question, but it recommends the following: $ git log -1 # note the SHA-1 of latest commit $ git checkout master # reset your branch head to your previously detached commit $ git reset --hard <commit-id> What exactly will "checking out the master" do? I just don't want to lose the changes I've made... screenshot of gitk:

PECL install fails

- by James

Hey! I have browsed every Google result, read all the forum posts about this error, but I cannot solve it. When using PECL install for anything, I always end up getting this error: checking whether the C compiler works... configure: error: cannot run C compiled programs. Everything else succeeds up to that point them bam! I'm using CentOS 4.3, PEAR is the latest stable version, GCC is a stable and recent version. Everything is working as it should, but the C compiler always seems to error. I've tried to make tmp have the right privilages for the operation by temporarily enabling it using: mount -o remount,exec,suid /tmp But that doesn't work. I've literally tried everything that has been suggested by to no avail. Any ideas?

Validate a single property with the Fluent Validation Library for .Net

- by Blegger

Can you validate just a single property with the Fluent Validation Library, and if so how? I thought this discussion thread from January of 2009 showed me how to do it via the following syntax: validator.Validate(new Person(), x => x.Surname); Unfortunately it doesn't appear this works in the current version of the library. One other thing that led me to believe that validating a single property might be possible is the following quote from Jeremy Skinners' blog post: "Finally, I added the ability to be able to execute some of FluentValidation’s Property Validators without needing to validate the entire object. This means it is now possible to stop the default “A value was required” message from being added to ModelState. " However I do not know if that necessarily means it supports just validating a single property or the fact that you can tell the validation library to stop validating after the first validation error.

TypeConverter for serialization

- by Cat

Is it normal practice to use a TypeConverter for serialization? There is a class that I do not own that has a "lossy" TypeConverter. When converting to a string, it formats its floating point data with "G4", so that when this type is displayed in a PropertyGrid, it's easily readable. I would like to also use this TypeConverter to convert from a string, creating an instance of this class. Right now I am checking the CultureInfo passed to TypeConverter.ConvertTo and only using the pretty, lossy conversion if the CultureInfo is not InvariantCulture. I'd like to know if I'm going about this the wrong way.

android: using listpreference and retrieving key string...

- by Allan

I have a settings menu that pops up and in it is a listpreference type menu. It is associated with a settings.xml file where there are 'array-strings' within it. It all works good but I don't know how to retrieve the users preference. As an example, let's say the user picks a color (red, green, or blue). The list that I've made within my 'array-strings' contain the text red, green, and blue. Within my code, I would like to do something if the user has choosen red, something else if they choose blue, etc., etc. Would I use a 'case' statement or an 'if' statement? And most importantly, how would I retrieve the users preference - the key? (am I checking for a boolean?) Help would be appreciated...thank you...

Android RTSP coding problem

- by NetApex

I have Googled my butt off trying to find where if there is a surefire way to make rtsp work. I have a radio station that I listen to that streams via rtsp. Of course by default Android doesn't want to play it. If I pop the URL into yourmuze.fm and create a station there it lets me stream it to my phone. After checking how it works I come to find that it streams to the phone via rtsp! So obviously there is something amiss. What makes one stream work and one not? This is the stream I am attempting : rtsp://wms2.christiannetcast.com/yes-fm It is an audio stream so I would be thrilled with most peoples problem of "it only does audio and not video." When yourmuze.fm streams, DDMS states it brings up MovieView to play the audio if that helps at all.

rendering JSON in GRAILS with part of the attributes of an object

- by bsreekanth

Hello, I am trying to build JSON from two fields. Say, I have a list of object(party), and I only need to pass 2 items as JSON pair. def list = getMyList() //it contains 2 party objects partyTo = array { for (i in list) { x partyId: i.id y partyName: i.toString() } } The JSON string is {"partyTo":[ {"partyId":12}, {"partyName":"Ar"}, {"partyId":9}, {"partyName":"Sr"} ] } when I extract it at the client, it is treated as 4 objects. I wanted as 2 objects, with the below format. {"partyTo":[ {"partyId":12 , "partyName":"Ar"}, {"partyId":9 , "partyName":"Sr"} ] } I'm getting 4 objects, probably because I use an array to build JSON. I'm new to groovy and JSON, so not sure about the right syntax combinations. Any help highly appreciated. thanks.

Testing sample code in python modules

- by Andrew Walker

I'm in the process of writing a python module that includes some samples. These samples aren't unit-tests, and they are too long and complex to be doctests. I'm interested in best practices for automatically checking that these samples run. My current project layout is pretty standard, except that there is an extra top level makefile that has build, install, unittest, coverage and profile targets, that delegate responsibility to setup.py and nose as required. projectname/ Makefile README setup.py samples/ foo-sample foobar-sample projectname/ __init__.py foo.py bar.py tests/ test-foo.py test-bar.py I've considered adding a sampletest module, or adding nose.tools.istest decorators to the entry-point functions of the samples, but for a small number of samples, these solutions sound a bit ugly. This question is similar to http://stackoverflow.com/questions/301365/automatically-unit-test-example-code, but I assume python best practices will differ from C#

Will html5 change everything for designers?

- by Sean Thompson

What impact do you think html5 will have on the workflow/way graphic design is done for the web? Right now most designers stay in an Adobe tool, doing most of the design work there, and implement some elements with graphics and some with code. Checking out http://www.apple.com/html5/ it seems that almost everything done in a graphic can be done in code. Will designers have to learn very advanced levels of html5 and do the actual design work in the browser or do you see a more "designer friendly" gui being made for html/graphics work? Will tools like photoshop evolve in a way that handles this new lack of image files?

How to use LIKE query in sqlite & iPhone

- by 4thSpace

I'm using the following for a LIKE query. Is this technique for LIKE correct? selectstmtSearch = nil; if(selectstmtSearch == nil){ const char *sql = "SELECT col1, col2 FROM table1 t1 JOIN table2 t2 ON t1.cityid = t2.cityid where t1.cityname like ?001 order by t1.cityname"; if(sqlite3_prepare_v2(databaseSearch, sql, -1, &selectstmtSearch, NULL) == SQLITE_OK) { sqlite3_bind_text(selectstmtSearch, 1, [[NSString stringWithFormat:@"%%%@%%", searchText] UTF8String], -1, SQLITE_TRANSIENT); } } The problem I'm having is after a few uses of this, I get an error 14 on sqlite3_open(), which is unable to open database. If I replace the LIKE with something such as: SELECT col1, col2 FROM table1 t1 JOIN table2 t2 ON t1.cityid = t2.cityid where t1.cityname = ? order by t1.cityname It works fine. I do open/close the DB before after the above code. Is there a way to troubleshoot exactly why the database can't be opened and what its relationship to my LIKE syntax is?

Visual Studio 2010 Extensibility, MPF and language services

- by MainMa

Hi, I am trying to extend Visual Studio 2010 RC to be able to use a custom programming language. The first two things I've tried to do is a syntax highlight/Intellisense feature (easily done, thanks to "Ook!" sample from PDC09) and a possibility to create new project templates (i.e. be able to open *.myproj files). For this second task, I can't find any easy tutorials or samples. Most samples are for Visual Studio 2008 (as for IronPython integration) or even VS2003. The few samples available for VS2010 do not work (including MPFProj) or do not compile, and are too hard to understand. Is there any easy-to-understand sample, either using MPFProj or a standalone solution, showing how to integrate templates for a custom language inside Visual Studio 2010?

Problem copying files through xcopy using VBScript

- by sushant

I am using VBScript to copy files using xcopy. The problem is that the folder path has to be entered by the user. Assuming I put that path in a variable, say h, how do I use this variable in the xcopy command? Here is the code I tried: Dim WshShell, oExec, g, h h = "D:\newfolder" g = "xcopy $h D:\y\ /E" Set WshShell = CreateObject("WScript.Shell") Set oExec = WshShell.Exec(g) I also tried &h but it did not work. Could anyone help me work out the correct syntax? Any help is appreciated.

Only first table in create table statement being created

- by Craig

The table "credentials" does show up in the adb shell. I've checked logcat and it doesn't seem to report a problem... private static final String DATABASE_CREATE = "create table credentials (_id integer primary key autoincrement, " + "username text not null, password text not null, " + "lastupdate text);" + "create table user (_id integer primary key autoincrement, " + "firstname text not null, " + "lastname text not null);" + "create table phone (_phoneid integer primary key autoincrement, " + "userid integer not null, phonetype text not null, " + "phonenumber text not null);" + "create table email (_emailid integer primary key autoincrement, " + "userid integer not null, emailtype text not null, " + "emailaddress text not null);" + "create table address (_addressid integer primary key autoincrement," + "userid integer not null, addresstype text not null, " + "address text not null);" + "create table instantmessaging (_imid integer primary key autoincrement, " + "userid integer not null, imtype text not null, " + "imaccount text not null);"; I've been pouring over this and I bet its some silly syntax typo! Or, at least I hope it is something trivial ;-) Craig

Use Any() and Count() in Dynamic Linq

- by ArpanDesai

I am trying to write dynamic Linq Library query to fetch record on condition, Customers who has order count is greater than 3 and ShipVia field equal 2. Below is my syntax what i have tried. object[] objArr = new object[10]; objArr[0] = 1; IQueryable<Customer> test = db.Customers.Where("Orders.Count(ShipVia=2)", objArr); and IQueryable<Customer> test = db.Customers.Where("Orders.Any(ShipVia=2).Count()", objArr); But both are not working. In second query Any returns true so it won't work with Count. Suggest me a way to implement this.

How to prevent code/option injection in a bash script

- by asmaier

I have written a small bash script called "isinFile.sh" for checking if the first term given to the script can be found in the file "file.txt": #!/bin/bash FILE="file.txt" if [ `grep -w "$1" $FILE` ]; then echo "true" else echo "false" fi However, running the script like > ./isinFile.sh -x breaks the script, since -x is interpreted by grep as an option. So I improved my script #!/bin/bash FILE="file.txt" if [ `grep -w -- "$1" $FILE` ]; then echo "true" else echo "false" fi using -- as an argument to grep. Now running > ./isinFile.sh -x false works. But is using -- the correct and only way to prevent code/option injection in bash scripts? I have not seen it in the wild, only found it mentioned in ABASH: Finding Bugs in Bash Scripts.

html hyperlinks show URL in brackets in Entourage

- by Rafe

I have an email script written in .Net that sends html emails. The email uses normal html hyperlinks to insert a link in the email, like this: <a href="http://www.stackoverflow.com/">StackOverflow</a> The problem is that in Entourage, a hyperlink like this always shows up for me like this: StackOverflow < http://www.stackoverflow.com/ > How can I format the hyperlink in my email so that in Entourage the text "StackOverflow" is the actual hyperlink, and the URL is not displayed after the text? Is there an html meta tag that needs to be set? Do I have to set the content-type somewhere? Or is there a different html syntax on the hyperlink itself that I should use?

Issue parsing RSS xml

- by cw

Hello, I'm having an issue using Linq to XML parsing the following XML. What I am doing is getting the element checking if it's what I want, then moving to the next. I am pretty sure it has to do with the xmlns, but I need this code to work with both this style and normal style RSS feeds (no xmlns). Any ideas? <?xml version="1.0" encoding="UTF-8"?> <rdf:RDF xmlns:rdf="http://someurl" xmlns:dc="http://purl.org/dc/elements/1.1/" xmlns:sy="http://purl.org/rss/1.0/modules/syndication/"> <channel rdf:about="http://someurl"> XElement currentLocation = startElementParameter; foreach (string x in ("channel\\Title").Split('\\')) { if (condition1 == false) { continue; } else if (condition2 == false) { break; } else { // This is returning null. currentLocation = currentLocation.Element(x); } } Thanks!
