    - by Phil
    Here is a method from msdn to provide data to an autocomplete extender / textbox: <System.Web.Services.WebMethodAttribute(), System.Web.Script.Services.ScriptMethodAttribute()> _ Public Shared Function GetCompletionList(ByVal prefixText As String, ByVal count As Integer, ByVal contextKey As String) As String() ' Create array of movies Dim movies() As String = {"Star Wars", "Star Trek", "Superman", "Memento", "Shrek", "Shrek II"} ' Return matching movies Return From m In movies(6) Where _ (m.StartsWith(prefixText, StringComparison.CurrentCultureIgnoreCase)) Select m).Take(count).ToArray() End Function The errors are: m.StartsWith - ('Startswith' is not a member of 'Char') Select m - ('Select Case' must end with a matching end select) .Take(count).ToArray() - (End of statement expected) Can you please let me know how to get this function working?

  • Howto extract text from a file where date -time is the index

    - by Soham
    I have got around 800 files of maximum 55KB-100KB each where the data is in this format Date/Time/Float1/Float2/Float3/Float4/Integer Date is in DD/MM/YYYY format and Time is in the format of HH:MM Here the date ranges from say 1st May to 1June and each day, the Time varies from 09:00 to 15:30. I want to run a program so that, for each file, it extracts the data pertaining to a particular given date and writes to a file. I will not face any problem in writing into directory operations. I am trying to get around, to form a to do a search and extract operation. I dont know, how to do it, would like to have some idea. Thanks Soham

  • Is there any way to limit the size of an STL Map?

    - by Nathan Fellman
    I want to implement some sort of lookup table in C++ that will act as a cache. It is meant to emulate a piece of hardware I'm simulating. The keys are non-integer, so I'm guessing a hash is in order. I have no intention of inventing the wheel so I intend to use stl::map for this (though suggestions for alternatives are welcome). The question is, is there any way to limit the size of the hash to emulate the fact that my hardware is of finite size? I'd expect the hash's insert method to return an error message or throw an exception if the limit is reached. If there is no such way, I'll simply check its size before trying to insert, but that seems like an inelegant way to do it.

  • How to transform a vector<int> into a string?

    - by Legend
    I am trying to pass a value from C++ to TCL. As I cannot pass pointers without the use of some complicated modules, I was thinking of converting a vector to a char array and then passing this as a null terminated string (which is relatively easy). I have a vector as follows: 12, 32, 42, 84 which I want to convert into something like: "12 32 42 48" The approach I am thinking of is to use an iterator to iterate through the vector and then convert each integer into its string representation and then add it into a char array (which is dynamically created initially by passing the size of the vector). Is this the right way or is there a function that already does this?

  • Compile Error Using MutableClassToInstanceMap with Generics

    - by user298251
    I am getting the following compile error "The method putInstance(Class, T) in the type MutableClassToInstanceMap is not applicable for the arguments (Class, Number)" on the putInstance method call. Does anyone know what I am doing wrong?? Thanks! public class TestMutableClassToInstanceMap { public final MutableClassToInstanceMap<Number> identifiers = MutableClassToInstanceMap.create(); public static void main(String[] args) { ArrayList<Number> numbers = new ArrayList<Number>(); numbers.add(new Integer(5)); TestMutableClassToInstanceMap test = new TestMutableClassToInstanceMap(numbers); } public TestMutableClassToInstanceMap(Collection<Number> numbers){ for (Number number : numbers) { this.identifiers.putInstance(number.getClass(), number); //error here } this.identifiers.putInstance(Double.class, 5.0); // This works } }

  • Reported error code considered SQL Injection?

    - by inquam
    SQL injection that actually runs a SQL command is one thing. But injecting data that doesn't actually run a harmful query but that might tell you something valuable about the database, is that considered SQL injection? Or is it just used as part to construct a valid SQL injection? An example could be set rs = conn.execute("select headline from pressReleases where categoryID = " & cdbl(request("id")) ) Passing this a string that could not be turned into a numeric value would cause Microsoft VBScript runtime error '800a000d' Type mismatch: 'cdbl' which would tell you that the column in question only accepts numeric data and is thus probably of type integer or similar. I seem to find this in a lot of pages discussing SQL injection, but don't really get an answer if this in itself is considered SQL injection. The reason for my question is that I have a scanning tool that report a SQL injection vulnerability and reports a VBScript runtime error '800a000d' as the reason for the finding.

  • GoTo statements, and alternatives (help me please im new) (VB.net)

    - by qais
    Basically I posted a code snippet on a forum asking for help and people pointed out to me that using GoTo statements is very bad programming practise so I'm just wondering, why is it bad? And also what alternative is there to use, like for example in this program ive done for homework the user has to input their date of birth and if the month/date/year are invalid or unrealistic(using if statements checking the integer inputs size, if theres any better way to do this i'd appreciate if you could tell me that also :D) then how would i be able to loop back to ask them again? heres a little extract of my code retryday: Console.WriteLine("Please enter the day you were born : ") day = Console.ReadLine If day > 31 Or day < 1 Then Console.WriteLine("Please enter a valid day") GoTo retryday End If

  • Is strftime (hour) showing wrong time?

    - by ander163
    I'm using this line to get the beginning time of the first day of the month. t = Time.now.to_date.beginning_of_month.beginning_of_day When i display this using t.strftime("%A %b %e @ %l:%m %p") it shows: Monday Feb 1 @ 12:02 AM The hour is always 12 (instead of 00), and more wierd the minute changes to match the month in integers. For the February date, it shows 12:02 AM I use .prior_month and .next_month on the variable to move forward or backwards in time. So when I move to June, this would display as Tuesday June 1 @ 12:06 AM But when I just show the value of "t" using a straight t.to_s, I get this time of 00:00:00, which is what I expect: Mon Feb 01 00:00:00 -0700 2010 A similar error occurs using end_of_day, but the hour is always 11 PM and the minute is the same integer value that matches the month in integers, i.e the time is 11:06 PM in June, 11:02 PM in February. Qurky? Admittedly a noob to Rails. Thanks for any comments or explanations.

  • Efficient way to create/unpack large bitfields in C?

    - by drhorrible
    I have one microcontroller sampling from a lot of ADC's, and sending the measurements over a radio at a very low bitrate, and bandwidth is becoming an issue. Right now, each ADC only give us 10 bits of data, and its being stored in a 16-bit integer. Is there an easy way to pack them in a deterministic way so that the first measurement is at bit 0, second at bit 10, third at bit 20, etc? To make matters worse, the microcontroller is little endian, and I have no control over the endianness of the computer on the other side.

  • C++ enumerations and compiler dependency

    - by dougie
    I currently have code with an enum where one value is set and the rest are left to be set by the compiler using the previous value +1, or so I hope. Is this functionality within an enumerated type compiler dependant, an example is below to clarify. enum FUNC_ERROR_CODE { FUNC_SUCCESS, FUNC_ERROR_1 = 24, FUNC_ERROR_2, FUNC_ERROR_3 } Is it safe to assume that FUNC_ERROR_2 will have the value 25 and FUNC_ERROR_3 will have the value 26, regardless of compliler used. I'm coding this so as a function can return an integer value, 0 is always success and any other value can signify failure.

  • ASP.Net partially ignoring my Custom error section in web.config

    - by weevie
    Here's my web.config customErrors section (you'll notice I've switched the mode to 'On' so I can see the redirect on my localhost): <customErrors defaultRedirect="~/Application/ServerError.aspx" mode="On" redirectMode="ResponseRewrite"> <error statusCode="403" redirect="~/Secure/AccessDenied.aspx" /> </customErrors> and here's the code that throws: Catch adEx As AccessDeniedException Throw New HttpException(DirectCast(HttpStatusCode.Forbidden, Integer), adEx.Message) End Try and here's what I end up with: Which is not my pretty AccessDenied.aspx page but it is a forbidden error page so at least I know my throw is working. I've removed the entry for 403 in IIS (7.0) as a desperate last attempt and unsuprisingly that made no difference. I've run out of ideas now so any suggestions will be gratefully appreciated!

  • VB.NET overloading array access?

    - by Wayne Werner
    Hi, Is it possible to overload the array/dict access operators in VB.net? For example, you can state something like: Dim mydict As New Hashtable() mydict.add("Cool guy", "Overloading is dangerous!") mydict("Cool guy") = "Overloading is cool!" And that works just fine. But what I would like to do is be able to say: mydict("Cool guy") = "3" and then have 3 automagically converted to the Integer 3. I mean, sure I can have a private member mydict.coolguy and have setCoolguy() and getCoolguy() methods, but I would prefer to be able to write it the former way if at all possible. Thanks

  • Algorithm: How to tell if an array is a permutation in O(n)?

    - by Iulian Serbanoiu
    Hello, Input: A read-only array of N elements containing integer values from 1 to N. And a memory zone of a fixed size (10, 100, 1000 etc - not depending on N). How to tell in O(n) if the array represents a permutation? --What I achieved so far:-- I use the limited memory area to store the sum and the product of the array. I compare the sum with N*(N+1)/2 and the product with N! I know that if condition (2) is true I might have a permutation. I'm wondering if there's a way to prove that condition (2) is sufficient to tell if I have a permutation. So far I haven't figured this out ... Thanks, Iulian

  • How to generate C# documentation to a CHM or HTML file?

    - by BrunoLM
    Is there a way to generate a readable document file from the documentation on the code directly from Visual Studio? (also considering 2010) If there isn't, what should I use to create a CHM or HTML file? Code example: /// <summary> /// Convert a number to string /// </summary> /// <param name="number">An integer number to be converted to string</param> /// <returns>Number as string</returns> /// <example> /// <code> /// var s = MyMethod(5); /// </code> /// </example> /// <exception cref="Exception">In case it can't convert</exception> /// <remarks> /// Whatever /// </remarks> public string MyMethod(int number) { return number.ToString(); }

  • mvc 2.0 updatemodel and my ID Column

    - by femi
    Hello, I have created a create view within my MVC 2.0 Application and by default it included a field for the integer ID Column. This is definitely a field i do not need. If i remove the field and use updatemodel when trying to create the object in code, will something break because it doesnt see my ID column data being passed in, even though it is auto increment? Also, i noticed that in the NerdDinner example, updatemodel was used and after that the repository.save method was called. I thought that updatemodel would save the object to the database..why then call the .save method afterwards? Or have i missed something? Any help with this would be appreciated. Cheers

  • JavaScript distributed computing project

    - by Ben L.
    I made a website that does absolutely nothing, and I've proven to myself that people like to stay there - I've already logged 11+ hours worth of cumulative time on the page. My question is whether it would be possible (or practical) to use the website as a distributed computing site. My first impulse was to find out if there were any JavaScript distributed computing projects already active, so that I could put a piece of code on the page and be done. Unfortunately, all I could find was a big list of websites that thought it might be a cool idea. I'm thinking that I might want to start with something like integer factorization - in this case, RSA numbers. It would be easy for the server to check if an answer was correct (simply test for modulus equals zero), and also easy to implement. Is my idea feasible? Is there already a project out there that I can use?

  • Strategies for Error Handling in .NET Web Services

    - by Jarrod
    I have a fairly substantial library of web services built in .NET that I use as a data model for our company web sites. In most .NET applications I use the Global ASAX file for profiling, logging, and creating bug reports for all exceptions thrown by the application. Global ASAX isn't available for web services so I'm curious as to what other strategies people have come up with to work around this limitation. Currently I just do something along these lines: <WebMethod()> _ Public Function MyServiceMethod(ByVal code As Integer) As String Try Return processCode(code) Catch ex As Exception CustomExHandler(ex) 'call a custom function every time to log exceptions Return errorObject End Try End Function Anybody have a better way of doing things besides calling a function inside the Catch?

  • Modifying records in my migration throws an authlogic error

    - by nfm
    I'm adding some columns to one of my database tables, and then populating those columns: def self.up add_column :contacts, :business_id, :integer add_column :contacts, :business_type, :string Contact.reset_column_information Contact.all.each do |contact| contact.update_attributes(:business_id => contact.client_id, :business_type => 'Client') end remove_column :contacts, :client_id end The line contact.update_attributes is causing the following Authlogic error: You must activate the Authlogic::Session::Base.controller with a controller object before creating objects I have no idea what is going on here - I'm not using a controller method to modify each row in the table. Nor am I creating new objects. The error doesn't occur if the contacts table is empty. I've had a google and it seems like this error can occur when you run your controller tests, and is fixed by adding before_filter :activate_authlogic to them, but this doesn't seem relevant in my case. Any ideas? I'm stumped.

  • Using Delphi or FFMpeg to create a movie from image sequence

    - by Hein du Plessis
    Hi all My Delphi app has created a squence called frame_001.png to frame_100.png. I need that to be compiled into a movie clip. I think perhaps the easiest is to call ffmpeg from the command line, according to their documentation: For creating a video from many images: ffmpeg -f image2 -i foo-%03d.jpeg -r 12 -s WxH foo.avi The syntax foo-%03d.jpeg specifies to use a decimal number composed of three digits padded with zeroes to express the sequence number. It is the same syntax supported by the C printf function, but only formats accepting a normal integer are suitable. From: http://ffmpeg.org/ffmpeg-doc.html#SEC5 However my files are (lossless) png format, so I have to convert using imagemagick first. My command line is now: ffmpeg.exe -f image2 -i c:\temp\wentelreader\frame_%05d.jpg -r 12 foo.avi But then I get the error: [image2 @ 0x133a7d0]Could not find codec parameters (Video: mjpeg) c:\temp\wentelreader\Frame_C:\VID2EVA\Tools\Mencoder\wentel.bat5d.jpg: could not find codec parameters What am I doing wrong? Alternatively can this be done easily with Delphi?
