• language to create flowcharts

  - by robintw

  Hi, This seems like something which must have been answered before, but I can't find anything appropriate in the question archives. Basically, I'm looking for a little Domain Specific Language to create flowcharts. I'm terrible at graphic design and making things look nice, and I'd really like a langauge where I could write something in code and it would produce a pretty flowchart. I've come across GraphViz, but it seems more suited to creating things like Finite State Machine diagrams, rather than process flowcharts. It also doesn't have the simple DSL-style front-end that would allow me to easily work it. Any ideas? I'm sure this must have been done before... Robin

Any help would be appreciated.

• InApp Purchase on slow network

  - by Chandan Shetty SP

  My InApp purchase code works fine in normal network, but in very slow network(safari browser will take 5 min to load a webpage). I am not getting any delegates... - (void)requestDidFinish:(SKRequest *)request - (void)request:(SKRequest *)request didFailWithError:(NSError *)error - (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response So my code blocks indefinetly because i am setting setUserInteractionEnabled to FALSE initially and setting it back to TRUE in the above delegates... [[[UIApplication sharedApplication]keyWindow]setUserInteractionEnabled:FALSE]; Is it possible to check the network status before creating "SKProductsRequest" or any better way to implement inApp Purchase? Thanks in advance,

• Create an assembly in memory

  - by Jared I

  I'd like to create an assembly in memory, using an using the classes in Reflection.Emit Currently, I can create the assembly and get it's bytes using something like AssemblyBuilder builder = AppDomain.CurrentDomain.DefineDynamicAssembly(..., AssemblyBuilderAccess.Save); ... create the assembly ... builder.Save(targetFileName); using(FileStream fs = File.Open(targetFileName, FileMode.Open)) { ... read the bytes from the file stream ... } However, it does so by creating a file on the local filesystem. I don't actually need the file, just the bytes that would be in the file. Is it possible to create the assembly without writing any files?

• How to automate configurating DotNetNuke settings for several environments?

  - by Joosh21

  Are there any recommended methods for automating configuring DotnetNuke settings? We will have several instances of our DNN application (prod, beta, qa, dev, local, etc) and need to be able to configure them all the same and be able to make updates to them all with our future releases. The settings currently needed to be configured include Host Settings, Portal Settings and User Profile Definitions. Here are some approaches I have come up with so far: 1) Create a Configuration module and use SQL scripts for all the settings? Is it generally safe to manipulate the DNN tables directly? Often it is recommended to use APIs with many frameworks. 2) Create a Configuration module and implement IUpgradeable.UpgradeModule and programatically set the settings? 3) Create a PortalTemplate from a portal with the settings all set. I believe this will only work for creating new portals. I will not be able to update existing portals.

• Set binding for DataTemplate components in code

  - by Chouppy

  Hi; sorry if I'm not clear, it's not really clear in my head too (especially after trying to find my way in other posts :p) What I'm willing to do is creating DataGrids in code, with zero to numerous columns containing a button, which will call one same function but with a "parameter" (different for each column). Here is what I got so far : DataGrid created in code DataTemplate defined in the xaml resources (with a button) DataGridTemplateColumn which uses the above DataTemplate Is it possible to bind the button's properties (in the DataTemplate), to the DataGridTemplateColumn properties (in my case, the column header would be ok), and how? Is there a way to get an access to the DataTemplate components (the button for example) in code, and modify their properties? Is it possible (and not hazardous) to create a DataTemplate in code? I declared mine in xaml because I found a post advising to do so instead of code. Thanks for your help.

• Joomla template parameters and params.ini - file becomes unwritable after save.

  - by Moak

  I am using wamp and creating a Joomla template with changeable parameters. initially the message is The parameter file \templates\ssc_2010\params.ini is writable! once I make changes everything works as expected, except now i get the message: The parameter file \templates\ssc_2010\params.ini is unwritable! One solution is to brows to the directory, right click the file, select properties, and uncheck read-only. Again the file is writable but once I modify the parameters again it becomes read only again. I'm quite lazy and would like to prevent this from happening again, I've notice this happening in past projects, but now I have to work a lot with parameters so it becomes quite boring doing manual labor like that :P

• How to order a TimeZone list in .NET?

  - by reallyJim

  I have an ASP.NET web application that requires users to select their appropriate time zone so that it can correctly show local times for events. In creating a simple approach for selecting the time zone, I started by just using the values from TimeZoneInfo.GetSystemTimeZones(), and showing that list. The only problem with this is that since our application is primarily targeted at the United States, I'd like to show those entries first, basically starting with Eastern Time and working backwards (West) until I reach Atlantic time. What's a good approach to do this in code?

• Git pre-receive hook

  - by Ralphz

  Hi When you enable pre-receive hook for git repository: It takes no arguments, but for each ref to be updated it receives on standard input a line of the format: < old-value SP < new-value SP < ref-name LF where < old-value is the old object name stored in the ref, < new-value is the new object name to be stored in the ref and is the full name of the ref. When creating a new ref, < old-value is 40 0. Does anyone can explain me how do I examine all the files that will be changed in the repository if i allow this commit? I'd like to run that files through some scripts to check syntax and so on. Thanks.

• Caching pictures from Picasa

  - by Renat

  Hello all, I'm creating an offline-capable IPhone app for showing pictures on picasa. It was pretty simple to use JQTouch and Google Data API (via JSONP), so I was able to show the albums and thumbnails in 3 hours, however I want that data to be cached, and for that I'm going to use the HTML 5 Application Cache (via xxx.manifest file). Now the question is what hosts shall I write there in order to cache pictures hosted on picasa. So far I've seen something like lh6.google.com or lh4.ggpht.com does anybody knows the full list of servers?

• Why am I getting this WSDL SOAP error with authorize.net?

  - by Chad Johnson

  I have my script email me when there is a problem creating a recurring transaction with authorize.net. I received the following at 5:23AM Pacific time: SOAP-ERROR: Parsing WSDL: Couldn't load from 'https://api.authorize.net/soap/v1/service.asmx?wsdl' : failed to load external entity "https://api.authorize.net/soap/v1/service.asmx?wsdl" And of course, when I did exactly the same thing that the user did, it worked fine for me. Does this mean authorize.net's API is down? Their knowledge base simply sucks and provides no information whatsoever about this problem. I've contacted the company, but I'm not holding my breath for a response. Google reveals nothing. Looking through their code, nothing stands out. Maybe an authentication error? Has anyone seen an error like this before? What causes this?

• Pushing app to heroku problem

  - by Ryan Max

  Hi, I am trying to push my app to heroku and I get the following message: $ heroku create Creating electric-meadow-15..... done Created http://electric-meadow-15.heroku.com/ | [email protected]:electric-meadow-1 5.git $ git push heroku master ! No such app as fierce-fog-63 fatal: The remote end hung up unexpectedly It's weird that I am getting this now, I have pushed the app to heroku many times without issue. the especially weird thing is, fierce-fog-63 is an old app that I made a deleted a long time ago. Why is it now that heroku is trying to push to this app that doesn't exist anymore, especially when I have created a new one. Any suggestions?

• [AS3] htmlText not showing bold or italics font

  - by Conor

  So I have a MovieClip asset with a dynamic textfield sitting inside of it. I export my .fla as a .swc to use within Flash Builder 4, and create instances of the asset with code, populating the text dynamically from XML. My issue is that even though I have htmlText enabled, bold and italics tags don't appear to be working. I have a feeling it is because when I created the asset in Flash CS4, the text field makes you specify the font, and the subset of that to use (Regular, Bold, Oblique, etc). Is there any way to get the htmlText to render bold and italics tags properly without having to completely rethink the way I'm creating all these fields?

• Git merge command

  - by Bialecki

  I'm reading the following article: http://github.com/guides/keeping-a-git-fork-in-sync-with-the-forked-repo, where they mention essentially pulling in changes from two repos at the same time by creating the following alias: pu = !"git fetch origin -v; git fetch wycats -v; git merge wycats/master" This makes sense, but, as someone new to Git, I'm curious why the commands is that versus: pu = !"git fetch origin -v; git merge origin/master; git fetch wycats -v; git merge wycats/master" or something along those lines. Basically, I'm wondering why the argument to merge is wycats/master and how it knows about origin/master automatically. Looking for a quick explanation.

• Identifying NHibernate proxy classes

  - by Marc Gravell

  I'm not an NHibernate user; I write a serialization utility library. A user has logged a feature-request that I should handle NHibernate proxy classes, treating them the same as the actual type. At the moment my code is treating them as unexpected inheritance, and throwing an exception. The code won't know in advance about NHibernate (including no reference, but I'm not aftaid of reflection ;-p) Is there a robust / guaranteed way of detecting such proxy types? Apparently DataContractSerializer handles this fine, so I'm hoping it is something pretty simple. Perhaps some interface or [attribute] decoration. Also, during deserialization; at the moment I would be creating the original type (not the NHibernate type). Is this fine for persistence purposes? Or is the proxy type required? If the latter; what is required to create an instance of the proxy type?

• importing a project into a svn repository question

  - by ajsie

  im using netbeans for svn. i open a project in netbeans and then i import it to a svn repo. it seems that although im only importing the project folder, svn creates .svn folders in all folders within this project folder. why is that? i thought that i was only creating .svn folders to checked out projects, not imported ones? now this folder acts very weird, when i open this folder as a project in netbeans, netbeans treats it like a svn folder some way. is this normal? cause i want this one to not be under SVN.

• How to stop toggle event from being fired multiple times on mouseenter/mouseleave?

  - by Clean

  Hi, I'm using jQuery to toggle the visibility of a using the jQuery toggle method. The toggle is fired on the mouseenter and mouseleave event, thus creating the effect of the div to fold out on mouseenter and fold in on mouseleave. Problem is, if the user drags the mouse over the a few times and then leaves the , the div will toggle in and out several times. This can happen if the user accidentally moves around the mouse pointer in the are. Do anyone have any idea on how I can avoid this behavior? Thanx!

• Easy to use time-stamps in Python

  - by Morlock

  I'm working on a journal-type application in Python. The application basically permits the user write entries in the journal and adds a time-stamp for later querying the journal. As of now, I use the time.ctime() function to generate time-stamps that are visually friendly. The journal entries thus look like: Thu Jan 21 19:59:47 2010 Did something Thu Jan 21 20:01:07 2010 Did something else Now, I would like to be able to use these time-stamps to do some searching/querying. I need to be able to search, for example, for "2010", or "feb 2010", or "23 feb 2010". My questions are: 1) What time module(s) should I use: time vs datetime? 2) What would be an appropriate way of creating and using the time-stamp objects? Many thanks!

• Return a dynamic string from std::exception's `what`

  - by Shtééf

  I'm convinced at this point that I should be creating subclasses of std::exception for all my exception throwing needs. Now I'm looking at how to override the what method. The situation that I'm facing, it would be really handy if the string what returns be dynamic. Some pieces of code parse an XML file for example, and adding a position or line number to the error message is useful to me. What I'd like to know: what returns a const char *, which implies any catcher is likely not going to free the string. So I need some other place to store the result, but where would that be? (I need thread-safety.) what also includes throw() in its signature. While I can prevent my what from throwing anything, it seems to me that this method really isn't intended for anything too dynamic. If what is not the right place, then where should I be doing this instead?

• Custom jQuery dropdown

  - by Coughlin

  I am creating a custom simple dropdown using jQuery that hides/shows a element based on over state. The problem I have now is that when you go over the shown element it hides, you cant move your mouse in to the dropdown that was created. Any thoughts on how to fix that also, is there an easier way to do what I have? I am going to be reusing this and not sure the best way to set the code up for I dont need to copy/paste six times. $(function(){ $("#dog-nav").hover( function(){ $(".sub-drop-box-dog").show("fast"); }, function(){ $(".sub-drop-box-dog").hide("fast"); } ); $("#cat-nav").hover( function(){ $(".sub-drop-box-cat").show("fast"); }, function(){ $(".sub-drop-box-cat").hide("fast"); } ); });

• many-to-many query

  - by kofto4ka

  Hello, guys! I have a problem and I dont know what is better solution. Okay, I have 2 tables: posts(id, title), posts_tags(post_id, tag_id). I have next task: must select posts with tags ids for example 4, 10 and 11. Not exactly, post could have any other tags at the same time. So, how I could do it more optimized? Creating temporary table in each query? Or may be some kind of stored procedure? In the future, user could ask script to select posts with any count of tags (it could be 1 tag only or 10 at the same time) and I must be sure that method that I will choose would be the best method for my problem. Sorry for my english, thx for attention.

• Phantom updates due to decimal precision on calculated properties

  - by Jamie Ide

  This article describes my problem. I have several properties that are calculated. These are typed as decimal(9,2) in SQL Server and decimal in my C# classes. An example of the problem is: Object is loaded with a property value of 14.9 A calculation is performed and the property value is changed to 14.90393 When the session is flushed, NHibernate issues an update because the property is dirty Since the database field is decimal (9,2) the stored value doesn't change Basically a phantom update is issued every time this object is loaded. I don't want to truncate the calculations in my business objects because that tightly couples them to the database and I don't want to lose the precision in other calculations. I tried setting scale and precision or CustomType("Decimal(9,2)") in the mapping file but this appears to only affect schema generation. My only reasonable option appears to be creating an IUserType implementation to handle this. Is there a better solution?

• Nhibernate not tracking changes

  - by Lavinski

  I'm using nhibernate and it appears that changes to my new object are not persisted. After creating and saving an object I then modify it and commit the transaction. However none of the modifications are saved. The strange thing is this code was working previously and I have no idea what could cause this. Nothing was changed that's obviously related.. As an attempted work around I saved the object later in the procedure after all the changes where made however I was greeted with an Assertion Failure collection [] was not processed by flush. Any ideas?

• How to trace a raw (character) device stream on Unix ?

  - by Fabien

  I'm trying to trace what is transiting in a raw (character) device on an Unix system (ex: /dev/tty.baseband) for DEBUG purpose. I am thinking of creating a deamon that would: upon start rename /dev/tty.baseband to /dev/tty.baseband.old. create a raw node /dev/tty.baseband spawn two threads: Thread 1: reading /dev/tty.baseband.old writing into /dev/tty.baseband Thread 2: reading /dev/tty.baseband writing into /dev/tty.baseband.old This would work a little bit like a MITM process. I wonder if there is not a 'standard' way to do this.

• Is there a Oracle equivalent of mysqldump

  - by Rakhitha

  Is there a way to dump the content of a oracle table in to a file formated as INSERT statements. I can't use oradump as it is on GPL. I will be running it from a perl CGI script. I am looking for something to dump data directly from oracle server using a single command. Running a select and creating insert statements using perl is too slow as there will be lot of data. I know I can probably do this using spool command and a plsql block at server side. But is there a built in command to do this instead of formating the INSERT statements myself?
