  • Modify Address of asmx Method Call

    - by Adam
    When I'm making asmx web service calls from Silverlight, is there any way to have the (generated) SoapClient objects modify the address that they call the service on? Specifically, I'd like to tack on a QueryString value onto each call that the service makes. So if I have DataService.SilverlightServiceSoapClient C = new DataService.SilverlightServiceSoapClient(); Is there any way to do something like: C.Address += "?Foo=Bar"; Which would allow me to, from my WebMethod, say: HttpContext.Current.Request.QueryString["foo"]; Obviously I can modify my WebMethods to take this value in as a parameter, but I'd like to avoid doing that if possible.

  • Get the affinity of a SQLite column on Android

    - by Neil Traft
    The SQLite C library has a method, sqlite3_column_decltype(). But I cannot find any place where the Android SQLite API makes this method available. Is there any way to get the declared type of a column without running any SQL (i.e. can I avoid using PRAGMA table_info)? I could have used AbstractWindowedCursor.isBlob(), but it says that it will also return true if the field is NULL. I need something that will guarantee me a value equal to the column's declared type.

  • What are the main reasons against the Windows Registry?

    - by dbemerlin
    If i want to develop a registry-like System for Linux, which Windows Registry design failures should i avoid? Which features would be absolutely necessary? What are the main concerns (security, ease-of-configuration, ...)? I think the Windows Registry was not a bad idea, just the implementation didn't fullfill the promises. A common place for configurations including for example apache config, database config or mail server config wouldn't be a bad idea and might improve maintainability, especially if it has options for (protected) remote access. I once worked on a kernel based solution but stopped because others said that registries are useless (because the windows registry is)... what do you think?

  • Extracting Data Daily from MySQL to a Local MySQL DB

    - by Sunny Juneja
    I'm doing some experiments locally that require some data from a production MySQL DB that I only have read access to. The schemas are nearly identical with the exception of the omission of one column. My goal is to write a script that I can run everyday that extracts the previous day's data and imports it into my local table. The part that I'm most confused about is how to download the data. I've seen names like mysqldump be tossed around but that seems a way to replicate the entire database. I would love to avoid using php seeing as I have no experience with it. I've been creating CSVs but I'm worried about having the data integrity (what if there is a comma in a field or a \n) as well as the size of the CSV (there are several hundred thousand rows per day).

  • Why does C++ linking use virtually no CPU?

    - by John
    On a native C++ project, linking right now can take a minute or two, yet during this time CPU drops from 100% during compilation to virtually zero. Does this mean linking is primarily a disk activity? If so, is this the main area an SSD would make big changes? But, why aren't all my OBJ files (or as many as possible) kept in RAM after compilation to avoid this? With 4Gb of RAM I should be able to save a lot of disk access and make it CPU-bound again, no?

  • NoSQL for concurrent reads/writes

    - by Mickael Marrache
    After getting some performance issues for an application using a MySQL database, I'm thinking of using NoSQL solutions. My architecture is as follows: One application receives messages from the network at a high throughput (i.e. 50000 messages/sec). Each message is stored in the DB, so it's important for the write rate to be as fast as the arrival rate. Then, I also have some PHP pages that accesses the DB to get the data stored by the other application. It's important for me that the retrieved data is as relevant as possible (i.e. not old data, let's say not more than 5 seconds old). Also, the data is not critical, so I don't need any security mechanism to avoid losing the data. I see there are a lot of NoSQL solutions, but I don't know if they are all relevant. Could you please provide me some directions. Thanks

  • Updating Activity UI from Different Activity Method?

    - by stormin986
    I have a tab widget where one of the tabs is a chat-type feature. I want to update the chat data at an interval (variable depending on whether the chat tab is active or not). The best approach seemed to be using an AsyncTask in my main TabActivity class, as that would avoid any issues of the chat activity being destroyed while in the background, while an AsyncTask was running. I wanted to ensure that the Activity isn't destroyed and recreated, thus causing my AsyncTask to be unable to modify the actual active Activity's data. However, now that my AsyncTask is in the TabActivity activity, I don't have a direct way to call my Chat's ListAdapter notifyDataSetChanged() from my onPostExecute() method anymore. Is there a way to get a reference to a given Tab's current Activity from the TabHost/TabActivity? Or, alternatively, can I assume my chat activity will never be destroyed as a child activity of the TabActivity activity (well, never destroyed while the TabActivity is active at least), and then just put the AsyncTask in the Chat Activity?

  • ant: iterator over properties file

    - by scheibenkleister
    Hi, all my projects and their versions are defined in a properties file like this: ProjectNameA=0.0.1 ProjectNameB=1.4.2 I'd like to iterate over all projects and use there names and versions in an ant script. Right now, I read the entire properties file in help of the property task. Then I iterate over a given list in a for loop like this: <for list="ProjectNameA,ProjectNameB" param="project"> <sequential> <echo message="@{project} has version ${@{project}}" /> </sequential> </for> How can I avoid the duplication of the project names in the for loop. So basically iterate over each line and extract the name and the version of a project. Thanks.

  • Issues running python scripts in Command Prompt (Specifically with command line arguments)?

    - by dmanatunga
    I am trying to run my python scripts in DOS without calling python.exe first. I am specifically doing this in relation to running django-admin.py. I have C:\Python26 and C:\Python26\Scripts in my PATH. However, if I try running django-admin.py by doing: django-admin.py startproject helloworld I get the message: Type 'django-admin.py help' for usage. Now, after some experimentation, I realized the problem is that the secondary arguments to these scripts are not being passed for some reason, since I tried it with a some other python scripts I have. I know I could avoid this problem by simply doing: python C:\Python26\Scripts\django-admin.py startproject helloworld But I know it should be possible to run the first command only and get it to work, because I had it working before. I've looked everywhere, and not many places have been helpful so any idea would be useful for me at this point.

  • Is it possible to come over the time out issue for a function call in C#?

    - by infant programmer
    In my program I call a method xslTransform.Load(strXmlQueryTransformPath, xslSettings, new XmlUrlResolver()); The problem I am facing is: sometimes this function doesn't execute well within the time. Sometimes compiler raises the time out issue after a long time of trial.. which inturn causes this part of application to shut. That is what I want to avoid. So if it exceeds certain time say 10 seconds I need to recall the method. Is it possible to add some code lines adjacent to this, which can meet the requirement?

  • Can I join between two MySQL tables stores on separate machines?

    - by CuriousCoder
    I have a relatively light query that needs information from a local MySQL table along with another MySQL table which is stored on a physically separate machine (on the same network). I'm keen to avoid setting up replication just to facilitate this light query that only needs executed once a day. Is there any way that I can join with a table on a remote machine using one query? Or run a SELECT INTO into a local table. Notes I'm using C# & .NET 4.

  • <Tabcontrol and Canvas

    - by prajor
    Hello, I have following situation <stackpanel > <ViewBox height=25/ > <tabcontrol> <tabitem> <Canvas /> </tabitem> </tabcontrol> </stackpanel> Q1. I want stackpanel to fill the screen, tabcontrol to fill the remain portion after viewbox. How do I do that ? How do I avoid the tabcontrol shrinking based on the size of tab items. Q2. I want the canvas restricted to the tabitem size. Currently I put anything in the canvas and scorll it goes beyond the tab item. Any idea how to control this.

  • Can I change the database server and database a report is pointing to dynamically?

    - by Randy Minder
    I have a Crystal 2008 report that will be deployed to an InfoView server. There are four different databases the user might want to execute the report against. Each of the four databases have exactly the same schema. Only the data in each is different. Each database corresponds to a plant we have around the world. Instead of creating four different reports (each one connected to one of the four databases), am I able to dynamically change the server/database the report hits based on a value the user enters into a parameter? I'm really trying to avoid having to create four identical reports except for the database connection on each. If this isn't possible, how do developers typically deal with this sort of scenario? I would imagine it's fairly common. Thanks very much.

  • SVN - ignoring files already in repository

    - by Alex
    I have a configuration file in my project which needs to be in the repository (so new developers get it when they checkout the project). Each developer might change some values in the file locally - these changes should not be committed and I don't want them showing in the synchronization menu (I'm using eclipse and subversive if it matters). Note that I can't just set the svn:ignore property since it only works on files that aren't under version control - but I do want to keep a base version of the file in the repository. How can I avoid the file showing in synchronization without deleting it from repository? EDIT: A better description - what I actually need is to be able to set a "read-only" property on the config file, so it can't be changed in the repository as long as the property is on. Do you know anything like this? Thanks

  • jQuery - Animate function

    - by Arun Kumar
    I have a piece of code shown below: $(".tagArea li").mouseover(function(){ $(this).animate({ borderWidth: "2px" }, 1000 ); }); $(".tagArea li").mouseout(function () { $(this).animate({ borderWidth: "1px" }, 1000 ); }); When I try to hover it on a particular list item, it properly animates but doesn't stop doing just once. It keeps doing 2 or 3 times. How to avoid this, I 've tried many a times but no positive result occurs to me. Kindly help.

  • CoreData and many NSArrayController

    - by unixo
    In my CoreData Application, I've an outline view on left of main window, acting as source list (like iTunes); on the right I display a proper view, based on outline selection. Each view has its components, such as table view, connected to array controller, owned by the specific view. Very often different views display same data, for example, a table view of the same entity. From a performance point of view, is better to have a single array controller per entity and share it between all views or does CoreData cache avoid memory waste?

  • How to fix this python error? RuntimeError: dictionary changed size during iteration

  • Are PDO prepared statements sufficient to prevent SQL injection?

    - by Mark Biek
    Let's say I have code like this: $dbh = new PDO("blahblah"); $stmt = $dbh->prepare('SELECT * FROM users where username = :username'); $stmt->execute( array(':username' => $_REQUEST['username']) ); The PDO documentation says The parameters to prepared statements don't need to be quoted; the driver handles it for you. Is that truly all I need to do to avoid SQL injections? Is it really that easy? You can assume MySQL if it makes a difference. Also, I'm really only curious about the use of prepared statements against SQL injection. In this context, I don't care about XSS or other possible vulnerabilities.

  • Fluent NHibernate + multiple databases

    - by Pablote
    My project needs to handle three databases, that means three session factories. The thing is if i do something like this with fluent nhibernate: .Mappings(m = m.FluentMappings.AddFromAssembly(Assembly.GetExecutingAssembly())) the factories would pick up all the mappings, even the ones that correspond to another database I've seen that when using automapping you can do something like this, and filter by namespace: .Mappings(m = m.AutoMappings.Add(AutoMap.AssemblyOf().Where(t = t.Namespace == "Storefront.Entities"))) I havent found anything like this for fluent mappings, is it possible?? The only solutions I can think of are: either create separate assemblies for each db mapping classes or explicitly adding each of the entities to the factory configuration. I would prefer to avoid both, if possible. Thanks.

  • Android / Java rare and seemingly impossible exception causing force close

    - by Guzba
    Hello all, I have an interesting problem being reported to me from an android application I have published. I have a two-dimensional array that I am iterating through using two for loops like so: for (int i = 0; i < arr.length; ++i) { for (int j = 0; j < arr[i].length; ++j) { if (arr[i][j] != 0) // does stuff } } The problem is, somehow arr[i][j] != 0 is throwing an ArrayIndexOutOfBoundsException. But very rarely. I have thousands of people use the app on a daily basis and get maybe twenty force close reports. Is this something I can't avoid, maybe a problem with the phones memory, etc. or is there something I can do that I haven't thought of yet? Thanks.

  • Python: Pickling highly-recursive objects without using `setrecursionlimit`

    - by cool-RR
    I've been getting RuntimeError: maximum recursion depth exceeded when trying to pickle a highly-recursive tree object. Much like this asker here. He solved his problem by setting the recursion limit higher with sys.setrecursionlimit. But I don't want to do that: I think that's more of a workaround than a solution. Because I want to be able to pickle my trees even if they have 10,000 nodes in them. (It currently fails at around 200.) (Also, every platform's true recursion limit is different, and I would really like to avoid opening this can of worms.) Is there any way to solve this at the fundamental level? If only the pickle module would pickle using a loop instead of recursion, I wouldn't have had this problem. Maybe someone has an idea how I can cause something like this to happen, without rewriting the pickle module? Any other idea how I can solve this problem will be appreciated.

  • $.get sends prototype functions in request URL?

    - by pimvdb
    I have some prototype functions added to Object which in my opinion were practical in certain scenarios. However, I noticed that when I executed a $.get, the prototype functions are handled as data members and are sent like http://...?prototypefunc=false. This is rather useless as I don't supply these as data members, but they are added to the query string. To be exact, I have this code: Object.prototype.in = function() { for(var i=0; i<arguments.length; i++) if(arguments[i] == this) return true; return false; } $.get('http://localhost/test.php', {'test': 'foo'}, function(text) { }); The corresponding URL constructed is: http://localhost/test.php?test=foo&in=false How can I avoid this?

  • Importing a spreadsheet, but having trouble.

    - by Chris Phelps
    I have a form that allows a user to import a spreadsheet. This spreadsheet is generally static when it comes to column headers, but now the users want to be able to include an optional column (called Notes). My code crashes when I try to read the column from the spreadsheet if it doesn't exist. Dim objCommand As New OleDbCommand() objCommand = ExcelConnection() 'function that opens spreadsheet and returns objCommand Dim reader As OleDbDataReader reader = objCommand.ExecuteReader() While reader.Read() Dim Employee As String = Convert.ToString(reader("User")) Dim SerialNUM As String = Convert.ToString(reader("serialno")) **Dim Notes As String = Convert.ToString(reader("notes"))** If the spreadsheet contains a Notes column, all goes well. If not, crash. How can I check to see if the Notes column exists in the spreadsheet to avoid the crash?

  • Rails + simple role system through associative table

    - by user202411
    So I have the Ninja model which has many Hovercrafts through ninja_hovercrafts (which stores the ninja_id and the hovercraft_id). It is of my understanding that this kind of arrangement should be set in a way that the associative table stores only enough information to bind two different classes. But I'd like to use the associative table to work as a very streamlined authorization hub on my application. So i'd also like this table to inform my system if this binding makes the ninja the pilot or co-pilot of a given hovercraft, through a "role" field in the table. My questions are: Is this ugly? Is this normal? Are there methods built into rails that would help me to automagically create Ninjas and Hovercrafts associations WITH the role? For exemple, could I have a nested form to create both ninjas and hcs in a way that the role field in ninjas_hovercrafts would be also filled? If managing my application roles this way isn't a good idea, whats the non-resource heavy alternative (my app is being designed trying to avoid scalability problems such as excessive joins, includes, etc) thank you
