  • Caching Web UserControl by Propety is not working (Grr!)

    - by PapillonUK
    Here's my code behind: <PartialCaching(60, Nothing, "UsrCtl_WebUserControl.CacheString", Nothing, True)> _ Partial Class UsrCtl_WebUserControl Inherits System.Web.UI.UserControl Private _CacheString As String Public Property CacheString() As String Get Return _CacheString End Get Set(ByVal value As String) _CacheString = value End Set End Property End Class Here's the user control embedded in a page: <uc:wuc ID="wuc" runat="server" CacheString="A" /> And in another page: <uc:wuc ID="wuc" runat="server" CacheString="B" /> According to the docs this control should maintain a different, 60 second cached version for each value of the CacheString property. It doesn't work - it caches for 60 seconds, but only one cached copy is created regardless of what I put in the CacheString property. Anyone any ideas what i'm doing wrong? - After 4 hours of this I have no hair or nails left - please save my monitor from the brick.

  • running Echo from Java

    - by ripper234
    I'm trying out the Runtime.exec() method to run a command line process. I wrote this sample code, which runs without problems but doesn't produce a file at c:\tmp.txt. String cmdLine = "echo foo > c:\\tmp.txt"; Runtime rt = Runtime.getRuntime(); Process pr = rt.exec(cmdLine); BufferedReader input = new BufferedReader( new InputStreamReader(pr.getInputStream())); String line; StringBuilder output = new StringBuilder(); while ((line = input.readLine()) != null) { output.append(line); } int exitVal = pr.waitFor(); logger.info(String.format("Ran command '%s', got exit code %d, output:\n%s", cmdLine, exitVal, output)); The output is INFO 21-04 20:02:03,024 - Ran command 'echo foo c:\tmp.txt', got exit code 0, output: foo c:\tmp.txt

  • Beginner Java Question about Integer.parseInt() and casting

    - by happysoul
    so when casting like in the statement below :- int randomNumber=(int) (Math.random()*5) it causes the random no. generated to get converted into an int.. Also there's this method I just came across Integer.parseInt() which does the same ! i.e return an integer Why two different ways to make a value an int ? Also I made a search and it says parseInt() takes string as an argument.. So does this mean that parseInt() is ONLY to convert String into integer ? What about this casting then (int) ?? Can we use this to convert a string to an int too ? sorry if it sounds like a dumb question..I am just confused and trying to understand Help ?

  • MS Access "#Name?" in unbound field on SOME machines

    - by alkorya
    I have a datasheet form bound to table. I added 2 unbound fields and set their Control Source properties to user defined VBA functions: 1. ConcatRelated (http://allenbrowne.com/func-concat.html) 2. Custom function that returns a string: Public Function GetLowestSatatus(LookupField As String, JSAID As Integer) As String On Error Resume Next GetLowestSatatus = DLookup(LookupField, "JsaStatuses", "ID=" & DMin("StatusID", "Tasks", "JSAID =" & JSAID)) End Function It works fine on my and some other machines but there are machines I got "#Name?" in these 2 unbound fields. All machines configured identically. Any ideas? Thank you!

  • launch an app to record keep with greasemonkey

    - by acidzombie24
    I have my greasemonkey script scanning every page i visit for a specific string. I would like to recordkeep the variations of the string in a sqlite db. I'll have another app process this db everyonce in a while. What i dont know is HOW do i store the data into the sqlite db? i was thinking i can launch an executable automatically if the string was found but i dont know how to do that through javascript. Another alternative i thought was have a socket listen on a certain port and have some js magic but i couldnt think of a silent way to send data like that.

  • Is this class + constructor definition pattern overly redundant?

    - by Protector one
    I often come across a pattern similar to this: class Person { public string firstName, lastName; public Person(string firstName, string lastName) { this.firstName = firstName; this.lastName = lastName; } } This feels overly redundant (I imagine typing "firstName" once, instead of thrice could be enough…), but I can't think of a proper alternative. Any ideas? Maybe I just don't know about a certain design pattern I should be using here? Edit - I think I need to elaborate a little. I'm not asking how to make the example code "better", but rather, "shorter". In its current state, all member names appear 3 times (declaration, initialization, constructor arguments), and it feels rather redundant. So I'm wondering if there is a pattern (or semantic sugar) to get (roughly) the same behavior, but with less bloat. I apologize for being unclear initially.

  • Hibernate multi column discriminator

    - by shikarishambu
    I have a single lookup table that manages all lookups - legacy and new lookup table structure is context,name, code, value context is either legacy or new name is the name of the lookup - state, status etc...for example code is the code and value is the value associated with the code Is there a way to specify multiple columns as discriminators so that I can get all legacy state code/values or all new status code/values. Is there a different way to do this if discriminators cannot do it? <class name="com.company.domain.Lookup"> <id name="Id" column="id" type="big_integer"> <generator class="org.hibernate.id.TableHiLoGenerator" /> </id> <discriminator column="context" insert="false" /> <property name="code" type="string"/> <property name="value" type="string"/> <property name="desc" type="string"/> <subclass name="com.company.domain.LegacyLookup" discriminator-value="legacy">

  • Exchange IMAP4 connector - Error Event ID 2006

    - by MikeB
    A couple of users in my organisation use IMAP4 to connect to Exchange 2007 (Update rollup 9 applied) because they prefer Thunderbird / Postbox clients. One of the users is generating errors in the Application Log as follows: An exception Microsoft.Exchange.Data.Storage.ConversionFailedException occurred while converting message Imap4Message 1523, user "*******", folder *********, subject: "******", date: "*******" into MIME format. Microsoft.Exchange.Data.Storage.ConversionFailedException: Message content has become corrupted. ---> System.ArgumentException: Value should be a valid content type in the form 'token/token' Parameter name: value at Microsoft.Exchange.Data.Mime.ContentTypeHeader.set_Value(String value) at Microsoft.Exchange.Data.Storage.MimeStreamWriter.WriteHeader(HeaderId type, String data) at Microsoft.Exchange.Data.Storage.ItemToMimeConverter.WriteMimeStreamAttachment(StreamAttachmentBase attachment, MimeFlags flags) --- End of inner exception stack trace --- at Microsoft.Exchange.Data.Storage.ItemToMimeConverter.WriteMimeStreamAttachment(StreamAttachmentBase attachment, MimeFlags flags) at Microsoft.Exchange.Data.Storage.ItemToMimeConverter.WriteMimeAttachment(MimePartInfo part, MimeFlags flags) at Microsoft.Exchange.Data.Storage.ItemToMimeConverter.WriteMimePart(MimePartInfo part, MimeFlags mimeFlags) at Microsoft.Exchange.Data.Storage.ItemToMimeConverter.WriteMimeParts(List`1 parts, MimeFlags mimeFlags) at Microsoft.Exchange.Data.Storage.ItemToMimeConverter.WriteMimePart(MimePartInfo part, MimeFlags mimeFlags) at Microsoft.Exchange.Data.Storage.ImapItemConverter.<>c__DisplayClass2.<WriteMimePart>b__0() at Microsoft.Exchange.Data.Storage.ConvertUtils.CallCts(Trace tracer, String methodName, String exceptionString, CtsCall ctsCall) at Microsoft.Exchange.Data.Storage.ImapItemConverter.WriteMimePart(ItemToMimeConverter converter, MimeStreamWriter writer, OutboundConversionOptions options, MimePartInfo partInfo, MimeFlags conversionFlags) at Microsoft.Exchange.Data.Storage.ImapItemConverter.GetBody(Stream outStream) at Microsoft.Exchange.Data.Storage.ImapItemConverter.GetBody(Stream outStream, UInt32[] indices) From my reading around it seems that the suggestion is to ask users to log in to Outlook / OWA and view the messages there. However, having logged in as the users myself, the messages cannot be found either through searching or by browsing the folder detailed in the log entry. The server returns the following error to the client: "The message could not be retrieved using the IMAP4 protocol. The message has not been deleted and may be accessible using either Microsoft Outlook or Microsoft Office Outlook Web Access. You can also try contacting the original sender of the message to find out about the contents of the message. Retrieval of this message will be retried when the server is updated with a fix that addresses the problem." Messages were transferred in to Exchange by copying them from the old Apple Xserve, accessed using IMAP. So my question, finally: 1. Is there any way to get the IMAP Exchange connector to rebuild its cache of messages since it doesn't seem to be pulling them directly from the MAPI store? 2. Alternatively, if there is no database, any ideas on why these messages don't appear in Outlook or OWA would be gratefully received. Many thanks, Mike

  • Controlling Solr score/sort

    - by Znarkus
    I want to filter a property within a range, but items that does not have the property should come last in the result. My solution was to set it to -1 if the property was not set. +(property:[10000000001 TO 10000000019] property:"-1"^0.5) This doesn't work, since every document with property:-1 get a very high score, for some reason. Is there a way to reliably control the sorting here? Boosting the range instead would mean I must boost every other term, which I'd rather not do.

  • Replacing delimiter characters in file path

    - by salvationishere
    I'm developing a C# web application in VS 2008. I let the user select an input file and then I store the file path in a string variable. However, it stores this path as "C:\\folder\\...". So my question is how do I convert this file path into single "\"? To clarify more, this is my code in context. Currently it is entering the If Directory does not Exist section. protected void btnAppend_Click(object sender, EventArgs e) { string fullpath = Page.Request.PhysicalPath; fullpath.Replace('\\', '\'); if (!Directory.Exists(fullpath)) { string msg = "<h1>The upload path doesn't exist: {0}</h1>";

  • How do I calculate a good hash code for a list of strings?

    - by Ian Ringrose
    Background: I have a short list of strings. The number of strings is not always the same, but are nearly always of the order of a “handful” In our database will store these strings in a 2nd normalised table These strings are never changed once they are written to the database. We wish to be able to match on these strings quickly in a query without the performance hit of doing lots of joins. So I am thinking of storing a hash code of all these strings in the main table and including it in our index, so the joins are only processed by the database when the hash code matches. So how do I get a good hashcode? I could: Xor the hash codes of all the string together Xor with multiply the result after each string (say by 31) Cat all the string together then get the hashcode Some other way So what do people think? (If you care we are using .NET and SqlServer)

  • what is the best way to have a Generic Comparer

    - by oo
    I have a lot of comparer classes where the class being compared is simply checking the name property of the object and doing a string compare. For example: public class ExerciseSorter : IComparer<Exercise> { public int Compare(Exercise x, Exercise y) { return String.Compare(x.Name, y.Name); } } public class CarSorter : IComparer<Car> { public int Compare(Car x, Car y) { return String.Compare(x.Name, y.Name); } } what is the best way to have this code generic so i dont need to write redundant code over and over again.

  • Deserialize array values to .NET properties using DataContractJsonSerializer

    - by James Cadd
    I'm working with the DataContractJsonSerializer in Silverlight 4 and would like to deserialize the following JSON: { "collectionname":"Books", "collectionitems": [ ["12345-67890",201, "Book One"], ["09876-54321",45, "Book Two"] ] } Into classes like the following: class BookCollection { public string collectionname { get; set; } public List<Book> collectionitems { get; set; } } class Book { public string Id { get; set; } public int NumberOfPages { get; set; } public string Title { get; set; } } What's the proper place to extend DataContractJsonSerializer to map the unnamed first array element in "collectionitems" to the Id property of the Book class, the second element to the NumberOfPages property and the final element to Title? I don't have control over the JSON generation in this instance and would like the solution to work with the Silverlight subset of .NET. It would be great if the solution could perform the reverse for serialization as well.

  • getting the Contact's Birthday of a HTC Sense phone

    - by Pentium10
    I am not sure, but probably HTC Sense does the following, syncs my Facebook contacts to my phone along with their mobile number and their birthday. This shows well in the agenda and the user panel. But as it turns out it doesn't use the standard SDK way to store the birthdays. As if I use the following code to get the birthday of a contact it returns NO data for those contacts. public String getBirthday() { if (data.containsKey(BIRTHDAY)) { return CRUtils.getString(data, BIRTHDAY); } else { // read birthday Cursor c = ctx.getContentResolver() .query( Data.CONTENT_URI, new String[] { Event.DATA }, Data.CONTACT_ID + "=" + this.getId() + " AND " + Data.MIMETYPE + "= '" + Event.CONTENT_ITEM_TYPE + "' AND " + Event.TYPE + "=" + Event.TYPE_BIRTHDAY, null, null); if (c != null) { try { if (c.moveToFirst()) { String s = c.getString(0); this.setBirthday(s); return s; } } finally { c.close(); } } return ""; } } How can I fix this?

  • which toString() method can be used performance wise??

    - by Mrityunjay
    hi, I am working on one project for performance enhancement. I had one doubt, while we are during a process, we tend to trace the current state of the DTO and entity used. So, for this we have included toString() method in all POJOs for the same. I have now implemented toString() in three different ways which are following :- public String toString() { return "POJO :" + this.class.getName() + " RollNo :" + this.rollNo + " Name :" + this.name; } public String toString() { StringBuffer buff = new StringBuffer("POJO :").append(this.class.getName()).append(" RollNo :").append(this.rollNo).append(" Name :").append(this.name); return buff.toString(); } public String toString() { StringBuilder builder = new StringBuilder("POJO :").append(this.class.getName()).append(" RollNo :").append(this.rollNo).append(" Name :").append(this.name); return builder .toString(); } can anyone please help me to find out which one is best and should be used for enhancing performance.

  • Pointers, links, object and reference count

    - by EugeneP
    String a = "a"; // allocate memory and write address of a memory block to a variable String b = "b"; // in a and b hold addresses b = a; // copy a address into b. // Now what? b value is completely lost and will be garbage collected //* next step a = null; // now a does not hold a valid address to any data, // still data of a object exist somewhere, yet we cannot get access to it. Correct me if there's a mistake somewhere in my reflexions. My question is: suppose anInstance object of type Instance has a property ' surname ' anInstance.getSurname() returns "MySurname". now String s = anInstance.getSurname(); anInstance = null; question is - is it true that getSurname value, namely MySurname will not be garbage collected because and only because it has active reference counter 0, and if other properties of anInstance have a zero reference counter, they'll be garbage collected?

  • Custom "Very Long Int" Division Issue

    - by befall
    Hey everyone, So, for a very silly project in C++, we are making our own long integer class, called VLI (Very Long Int). The way it works (they backboned it, blame them for stupidity) is this: User inputs up to 50 digits, which are input as string. String is stored in pre-made Sequence class, which stores the string in an array, in reverse order. That means, when "1234" is input, it gets stored as [4|3|2|1]. So, my question is this: How can I go about doing division using only these arrays of chars? If the input answer is over 32 digits, I can't use ints to check for stuff, and they basically saying using long ints here is cheating. Any input is welcome, and I can give more clarification if need be, thanks everyone.

  • Force column order, Excel data table

  • Python appengine Query does not work when using a variable.

    - by Lloyd
    Hi, I am trying to use a fetcher method to retrieve items from my datastore. If I use the following def getItem(item_id): q = Item.all() q.filter("itemid = ", item_id) It fails because nothing is returned. If I hard code in an item like def getItem(item_id): q = Item.all() q.filter("itemid = ", 9000) it fetches just fine, and sings merrily along. I have tried every which way to get this to work. I have used result = db.GqlQuery("SELECT * FROM Item WHERE item_id = :1 LIMIT 1", title).fetch(1) to the same effect. If I hard code in a number, works fine. I have tried setting the select statement as a local string, assembling it that way, casting the int as a string, and nothing. When I output the SELECT statement to the screen, looks fine. I can cut ans paste the output into the string, and whammo, it works. Any help would be appreciated.

  • assignment vs std::swap and merging and keeping duplicates in seperate object

    - by rubenvb
    Say I have two std::set<std::string>s. The first one, old_options, needs to be merged with additional options, contained in new_options. I can't just use std::merge (well, I do, but not only that) because I also check for doubles and warn the user about this accordingly. To this effect, I have void merge_options( set<string> &old_options, const set<string> &new_options ) { // find duplicates and create merged_options, a stringset containing the merged options // handle duplicated the way I want to // ... old_options = merged_options; } Is it better to use std::swap( merged_options, old_options ); or the assignment I have? Is there a better way to filter duplicates and return the merged set than consecutive calls to std::set_intersection and std::set_union to detect dupes and merge the sets? I know it's slower than one traversal and doing both at once, but these sets are small (performance is not critical) and I trust the Standard more than I trust myself.
