• Modify .resx file at runtime

  - by Gerry Whitworth

  Building a ASP.NET MVC site and I would like to add some values to my .resx file at run time. I have tried: IResourceWriter writer = new ResourceWriter("myResources.resources"); writer.AddResource("String 3", "Third String"); writer.Close(); This code compiles and executes fine but after I close the website and look at the .resx file it is corrupt and I must re-create the .resx file again. Note that I have two values in this .resx file I added at design time. Thanks Gerry

• How to execute a large PHP Script ?

  - by atif089

  Well basically I may want to execute a script that may take as much as 1 hours as well. What I really want to do is Send SMS to my users using a third party API. So its basically like I supply my script with an array of phone numbers and fire the method to send SMS. However assuming it take 5 seconds to send 1 SMS and I want to send 1000 SMS which is roughly 1 - 2 hours. I can use set_time_limit() because I am on shared host. One way to do this is store numbers in a session and execute each SMS and use javascript to refresh that page until end. This way I need to keep my browser open and the execution will stop if my Internet Connection is disconnected. So, Is there any better way to do this ? Hope I am clear enough to explain what I want? I want to execute a large script that may take hours to execute without getting timeout.

  - by ThuL?nå F?rñ?nDö

  This is my assignment: Write a program where the user enters a string, and the program echoes it to the monitor with one character per line: C:\>java LinePerChar Enter a string: Octopus O c t o p u s I have tried, but I'm getting some compilation errors.

• Iterator blocks and inheritance.

  - by Dave Van den Eynde

  Given a base class with the following interface: public class Base { public virtual IEnumerable<string> GetListOfStuff() { yield return "First"; yield return "Second"; yield return "Third"; } } I want to make a derived class that overrides the method, and adds its own stuff, like so: public class Derived : Base { public override IEnumerable<string> GetListOfStuff() { foreach (string s in base.GetListOfStuff()) { yield return s; } yield return "Fourth"; yield return "Fifth"; } } However, I'm greeted with a warning that "access to a member through a base keyword from an iterator cannot be verified". What's the accepted solution to this problem then?

• Problem doing SVN Vendor Branch - merge

  - by Gyan

  Hi, I am trying to use the svn vendor branch to upgrade the third party library. (We have modified the source code) I followed all the steps to create the vendor branch:: created the vendor branch for old version (3rd party library) created the vendor branch for latest version (3rd party library) copied the latest version to current folder using (usign svn_load_dirs.pl script) structure of vendor repository in svn URL/vendor/library/3.5.0 URL/vendor/library/3.7.0 URL/vendor/library/current I have the library-3.5.0 used/modified at URL/trunk/library/customized-library I have a problem when I try to merge the difference between URL/vendor/library/3.7.0 and URL/vendor/library/3.5.0 to URL/trunk/library/customized-library I am at the folder where URL/trunk/library/customized-library is checked out and I use following command to do the merge svn merge URL/vendor/library/3.5.0 URL/vendor/library/current . --accept PARAMETERS when I use theirs-conflict for accept parameter, It ignores all of my changes to the old version and copies files from 3.7.0 when I user mine-conflict, it ignores the files in 3.7.0 when I use postpone, it throws exception "tree conflict" Thanks Gyan

• iFrames and Cookies

  - by Tom

  I have a site on A.com and an iframe on B.com which reads info from A.com. I realize that there is some problems with third party cookies, iframes and P3P - particularly in Safari [my problem] Is it possible to instead, use AJAX or a hidden iFrame to pass the cookie information from A.com to B.com which will then "recreate" another cookie with the same information on the iframe in B.com. I am trying to do this for authenication - i.e. a user is logged in on A.com and then goes to b.com and the iframe is also logged in ? I was hoping to perhaps pass the data in a hidden iframe and "recreate" the cookie in the iframe on B.com using JavaScript? Is this possible ? Security issues ? What about HTTPS?

• Allowing developer-specific settings in VS2008 projects

  - by Xavier Nodet

  Is it possible to combine the following properties, and if so, how? Store in our version control system some Visual Studio 2008 native C++ project files for the developers in our team that use this IDE. Allow some of those developers to tweak their projects (e.g. using debug version of third-party libraries instead of the usual ones). Make sure these modifications are done in files that are not versioned. In other words, I would like to allow developers to tweak some settings in their projects without risking that these changes are committed. An 'optional VSPROP' file approach seems doomed to fail, as VS2008 refuses to load projects that refer to non-existent VSPROP files... Any other suggestion? Is this possible with VS2010?

• PHP / javascript live chat using too much bandwidth

  - by David

  So I am learning about javascript, so I am making a live chat system with PHP and javascript. I have it so the javascript refreshes the log (each message gets logged in a file on the server), and it refreshes every second. Im using firebug to monitor the resource usage, and I see under the net tab each times its updated, and the bytes add up really fast. I know I can change it to update less, but is there a way that when a user on the other end I'm talking to, when the send a message, it gets sent to the server, then an alert gets sent to me saying that the chatlog needs to update somehow. That way it only updates when the log is updated. let me know, thanks

• JTA Transaction: What happens if an exception happens but rollback is not called on the transaction?

  - by kellyfj

  We have some third party code wherein they do the following 1) Create a User Transaction e.g. txn = (UserTransaction)ctx.lookup( "UserTransaction" ); txn.begin( ); 2) Do some work persisting to the database (via JPA) to a MySQL database 3) txn.commit() They have Exception blocks but NONE of them call txn.rollback. Good coding practice says they NEED to call rollback if an exception occurs but my question is If the txn is not commited, and an exception occurs what is the negative effect of them NOT calling rollback?

• c++ : list(vector) definition with array

  - by Meloun

  I have Class Email, there is parameter "bcc" in her construktor. Its actually list of emails for copies. There is no fixed number of these emails and later i have to have possibility to extend this list. //construktor prototype Email::Email(vector<string> bcc) So i want to use type vector or list for that and function push_back(). How can i make a new instance with bcc emails? I need actually declaration with definition for my list. I've found this definition with iterator for integer type: int myints[] = {16,2,77,29}; Email myEmail(vector<int> (myints, myints + sizeof(myints) / sizeof(int) )); , but its not very user friend and i need it with strings. Is there something like this? Email myEmail(vector<string> ("first","second","third"));

• Deciphering Encoding: Packet Analyzation Tools

  - by Zombies

  I am looking for better tools than wireshark for this. The problem with wireshark is that it does not format the data layer (which is the only part I am looking at) cleanly for me to compare the different packets and attempt to understand the third party encoding (which is closed source). Specifically, what are some good tools for viewing data, and not tcp/udp header information? Particularly, a tool that formats the data for comparison. To be very specific: I would like a program that compares multiple (not just 2) files in hex.

• How to manage changes to reports in .NET?

  - by Craig Johnston

  If I need to offer the ability to create, view and print reports from a .NET app, I see that there are 2 options: use a reporting component such as Microsoft.Reporting.WinForms.ReportViewer or Crystal Reports which saves a .rpt or similar template file that can be modified as required without having to re-compile the app use System.Drawing.Printing for reporting and store report template data in a database, which keeps things simpler and avoids problems with bulky third party reporting components If I want to be able to modify a report template (which would include layout and data fields) without having to re-compile the app, would the first option above achieve this? If I wanted to be able to modify the template without re-compiling the app, how could this be achieved with the second option? How could you store data representing the templates in a database such that it could be modified without having to re-compile the app?

• Validating XML with multiple XSDs in Java

  - by Arian

  Hello! I want to parse an XML file with Java and validate it in the same step against an XSD schema. An XML file may contain content of several schemas, like this: <outer xmlns="my.outer.namespace" xmlns:x="my.third.namespace"> <foo>hello</foo> <inner xmlns="my.inner.namespace"> <bar x:id="bar">world</bar> </inner> </outer> Given a namespace the corresponding xsd file can be provided, but the used namespaces are unknown before parsing. If a schema defines default values for attributes, I also want to know that somehow. I was able to validate a file if the schemas are known, I was able to parse a file without validation and I implemented a LSResourceResolver. However, I can't get all of it working together. How do I have to set up my (SAX) parser?

• Creating a ListView/TreeView using Category (Control Panel-Like) View

  - by Andrew Moore

  I currently have an application which uses a regular ListView with groups to show a bunch of modules. I would like to use a Category view. Category view is the new view introduced in Windows Vista for the Control Panel: Is there a third party control or a way (via API) to create a ListView which mimics the behavior of the Windows 7 Control Panel? Categories with icons and action links. Separate events for Category Click and Action Click. One or two column layout Separators between action links or lines EDIT: Seems like Windows is using a TreeView (SysTreeView32) control internally for this.

• Guaranteeing the onmouseout event to fire

  - by n3rd

  Hello everybody, I'm currently developing a web application and have run into a little problem. I'm using ExtJS, but I believe this to be a general JS question. When the cursor enters an HTML element, the onmouseover event is fired, when the cursor leaves that element, onmouseout is triggered. So far, so good. Unfortunately, it seems one can't fully rely on this behaviour. Very quick mouse movements can cause the event not to fire (as does repositioning the cursor with a pen tablet, for example). What are the best practices to handle these issues? Do I need to monitor all onmousemove events and manually keep track of where the cursor was last and fire the appropriate onmouseout event myself?

• Which technology should I choose for 3d globe web application

  - by uther-lightbringer

  Hello, i would like to ask you for an advice. I'm currently developing application in Spring consisting of Spring CRUD application as backend, SpringMVC application as tool for management and third part is where my problem lies as I need have application that renders 3d globe which is fed by data from backend from a data set selected by user (user may switch those at will). It has to be web application (though I would prefer not to implement this in flash/flex), composed of two main parts - main part is classic web GUI where user makes his choices and second part is 3d globe which renders the globe with selected set of data visualised. My question is, what do you think is the best option to implement this? Would be SpringMVC framework usable for this kind of application? I will be gratefull for any leads or directions, thank you.

• Dataset and Hierarchial Data How to Sort

  - by mdjtlj

  This is probably a dumb question, but I've hit a wall with this one at this current time. I have some data which is hierarchial in nature which is in an ADO.NEt dataset. The first field is the ID, the second is the Name, the third is the Parent ID. ID NAME Parent ID 1 Air Handling NULL 2 Compressor 1 3 Motor 4 4 Compressor 1 5 Motor 2 6 Controller 4 7 Controller 2 So the tree would look like the following: 1- Air Handling 4- Compressor 6 - Controller 3 - Motor 2- Compressor 7- Controller 5 - Motor What I'm trying to figure our is how to get the dataset in the same order that ths would be viewed in a treeview, which in this case is the levels at the appropriate levels for the nodes and then the children at the appropriate levels sorted by the name. It would be like binding this to a treeview and then simply working your way down the nodes to get the right order. Any links or direction would be greatly appreciated.

• Find top N elements in a Multiset from Google Collections?

  - by dfrankow

  A Google Collections Multiset is a set of elements each of which has a count (i.e. may be present multiple times). I can't tell you how many times I want to do the following Make a histogram (exactly Multiset) Get the top N values from the histogram Examples: top 10 URLs, top 10 tags, ... What is the canonical way to do #2 given a Multiset? Here is a blog post about it, but that code is not quite what I want. First, it returns everything, not just top N. Second, it copies (is it possible to avoid a copy?). Third, I usually want a deterministic sort, i.e. tiebreak if counts are equal.

• SNMP in Java, specifically to be JMX adapter.

  - by Ben

  Hi, I have a few JAVA application that I monitor using JMX. I would like to write an SNMP client for these applications that wraps the JMX interface and by discovery exposes the same attributes that are exposed in JMX, through SNMP. I have no problem writing the client if I just figure out how to write SNMP clients in JAVA. Is there a free SNMP library for JAVA that I can use? Is there a good free SNMP adapter for JMX? (Tried "WebNMS SNMP Adapter for JMX" trial unsuccessfully) Thank you!

• Fast exchange of data between unmanaged code and managed code

  - by vizcaynot

  Hello: Without using p/invoke, from a C++/CLI I have succeeded in integrating various methods of a DLL library from a third party built in C. One of these methods retrieves information from a database and stores it in different structures. The C++/CLI program I wrote reads those structures and stores them in a List<, which is then returned to the corresponding reading and use of an application programmed completely in C#. I understand that the double handling of data (first, filling in several structures and then, filling all of these structures into a list<) may generate an unnecessary overload, at which point I wish C++/CLI had the keyword "yield". Depending on the above scenario, do you have recommendations to avoid or reduce this overload? Thanks.

• code folding in Visual Studio for F#

  - by Yin Zhu

  I find that I tend to write long source files in F#. Some open source projects in F# also have long source files, e.g. FPersec and F# for excel. So it would be very helpful if code folding (even very limited support) is available in VS for F#. E.g. in a module, we can fold out functions that are stable, only leave functions that are subject to change unfold. Is this feature easy to be supported, e.g. by a third party vendor?

• Building Boost with LSB C++ Compiler

  - by Alex Farber

  I want to build my program with LSB C++ Compiler from the Linux Standard Base http://www.linuxfoundation.org/collaborate/workgroups/lsb. Program depends on the Boost library, built with gcc 4.4 version. Compilation fails. Is it possible to build the Boost library with LSB C++ Compiler? Alternatively, is it possible to build the Boost library with some old gcc version, what version is recommended? My final goal is to get my executable and third-party Boost libraries running on most Linux distributions. Generally, what can be done to get better binary compatibility for Linux distributions, developing C++ closed-source application depending on the Boost library?
