  • Why would a CSV attachment appear as text in the body?

    - by David
    Hi all I've just implemented some code that emails a bunch of our clients with a CSV file attachment. Some (not many) have got back to us complaining that they don't get an attachment at all - just the CSV text inside the body of the email. Most however are fine. I suspect that it's different mail clients that are treating the attachment differently but I don't have enough info yet to be sure. I'm using .NET's MailMessage class with the Attachment.CreateAttachmentFromString() method. The MIME type I'm specifying for the attachment is text/csv. Anyone have any idea what the heck is going on? Ta muchly David

  • Bubble chart with X and Y labels of string type [closed]

    - by MrGenius
    I have a scenario where I need to display how many males, females and Unspecified are there from City1, City2, City3, etc. I am trying to use bubble chart for this. So I want to display this chart with y axis showing Male, Female and Unspecified as Y axis labels and City1, City2,City3 as X axis labels. The actual count being displayed as a square bubble on the chart. This is little urgent. I could not locate any similar sample on MS documentation too. Edit: How to use the bubble chart to display genders on the y axis and cities on the x axis?

  • Using Amazon S3 for multiple remote data site uploads, securely

    - by Aitch
    I've been playing about with Amazon S3 a little for the first time and like what I see for various reasons relating to my potential use case. We have multiple (online) remote server boxes harvesting sensor data that is regularly uploaded every hour or so (rsync'ed) to a VPS server. The number of remote server boxes is growing regularly and forecast to keep growing (hundreds). The servers are geographically dispersed. The servers are also automatically built, therefore generic with standard tools and not bespoke per location. The data is many hundreds of files per day. I want to avoid a situation where I need to provision more VPS storage, or additional servers every time we hit the VPS capacity limit, after every N server deployments, whatever N might be. The remote servers can never be considered fully secure due to us not knowing what might happen to them when we are not looking. Our current solution is a bit naive and simply restricts inbound rsync only over ssh to known mac address directories and a known public key. There are plenty of holes to pick in this, I know. Let's say I write or use a script like s3cmd/s3sync to potentially push up the files. Would I need to manage hundreds of access keys and have each server customized to include this (do-able, but key management becomes nightmarish?) Could I restrict inbound connections somehow (eg by mac address), or just allow write-only to any client that was running the script? ( i could deal with a flood of data if someone got into a system? ) having a bucket per remote machine does not seem feasible due to bucket limits? I don't think I want to use a single common key as if one machine is breached then potentially, a malicious hack could get access to the filestore key and start deleting for ll clients, correct? I hope my inexperience has not blinded me to some other solution that might be suggested! I've read lots of examples of people using S3 for backup, but can't really find anything about this sort of data collection, unless my google terminology is wrong... I've written more than I should here, perhaps it can be summarised thus: In a perfect world I just want to have one of our techs install a new remote server into a location and it automagically starts sending files home with little or no intervention, and minimises risk? Pipedream or feasible? TIA, Aitch

  • scripsharp reference web service / strongly type to results model

    - by user175528
    With scriptsharp (script#) is it possible to get strong typing when calling a service defined in my web app? The only way I can see is to: 1 - use linked / shared files to shadow copy my results classes / domain models across into my script# lib 2 - replicate my model across in the script# lib and use automapper to validate? 3 - use some .tt to code gen? also, even if I can do this, how do I get around the auto camel-casing script# does, when my service result (asmx) wont do this? (so my JSON response will comback as UserMessage, script# will have changed that to userMessage) basically, what I am looking to use script# to achieve is better compile time support against our domain model when calling and processing services in javascript, so something like this: Scriptlet public static class MyScriptlet { public static void Main() { MyService.Service1("hello", ProcessResponse);} public static void ProcessResponse(MyService.Service1ResponseData resp) { jQuery.Select('#Message').Text(resp.UserMessage); jQuery.Select('#Detail').Text(resp.UserDetail); } Service (in our web app) public class MyService { public class Service1ResponseData { public string UserMessage {get;set;} public string UserDetail {get;set;} } public Service1ResponseData Service1(string user) { return new Service1ResponseData() { UserMessage:"hi",UserDetail:"some text"}; } }

    I have been playing around with different data clustering algorithms working on finding clusters between random data points represented an nodes, I keep reading that data clustering is used for image recognition. I am failing to make the connection, how does clustering data help in recognizing an image or in facial recognition. can someone explain this?

  • How to use Object.GetHashCode() on a type that overrides GetHashCode()

    - by Jimmy
    Hi, I have a class A that implements IEquatable<, using its fields (say, A.b and A.c) for implementing/overriding Equals() and overriding GetHashCode(), and everything works fine, 99% of the time. Class A is part of a hierarchy (class B, C) that all inherit from interface D; they can all be stored together in a dictionary Dictionary, thus it's convenient when they all carry their own default Equals()/GetHashCode(). However, while constructing A I sometime need to do some work to get the values for A.b and A.c; while that's happening, I want to store a reference to the instance that's being built. In that case, I don't want to use the default Equals()/GetHashCode() overrides provided by A. Thus, I was thinking of implementing a ReferenceEqualityComparer, that's meant to force the use of Object's Equals()/GetHashCode(): private class ReferenceEqualityComparer<T> : IEqualityComparer<T> { #region IEqualityComparer<T> Members public bool Equals(T x, T y) { return System.Object.ReferenceEquals(x, y); } public int GetHashCode(T obj) { // what goes here? I want to do something like System.Object.GetHashCode(obj); } #endregion } The question is, since A overrides Object.GetHashCode(), how can I (outside of A) call Object.GetHashCode() for an instance of A? One way of course would be for A to not implement IEquatable< and always supply an IEqualityComparer< to any dictionary that I create, but I'm hoping for a different answer. Thanks

  • NHibernate CreateSQLQuery data conversion from bit to boolean error

    - by RemotecUk
    Hi, Im being a bit lazy in NHibernate and using Session.CreateSqlQuery(...) instead of doing the whole thing with Lambda's. Anyway what struct me is that there seems to be a problem converting some of the types returned from (in this case the MySQL) DB into native .Net tyes. The query in question looks like this.... IList<Client> allocatableClients = Session.CreateSQLQuery( "select clients.id as Id, clients.name as Name, clients.customercode as CustomerCode, clients.superclient as SuperClient, clients.clienttypeid as ClientType " + ... ... .SetResultTransformer(new NHibernate.Transform.AliasToBeanResultTransformer(typeof(Client))).List<Client>(); The type in the database of SuperClient is a bit(1) and in the Client object the type is a bool. The error received is: System.ArgumentException: Object of type 'System.UInt64' cannot be converted to type 'System.Boolean'. It seems strange that this conversion cannot be completed. Would be greatful for any ideas. Thanks.

  • where on disk is space allocated for new files inside LVM lv with ext4 file system?

    - by Jost
    I run a multi-disk server with LVM2. Several large disks serve as LVM2 physical volumes for one volume group, containing one logical volume formatted with ext4. Nothing fancy, just your standard linear setup. Recently an additional, very small disk was added as physical volume to that volume group and I expanded both the logical volume, and the ext4 file system therein onto that disk. This lv is used to store incremental backups using rsync and is only about 30% full, there have rarely been any files deleted from it, only incremental writes. Now this new HDD I added to the pre-existing volume group has unexpectedly died on me, and the volume group won't come up because it is missing one physical volume. As fate will have it, this WAS the "in an event of catastrophic failure on the primary server"-backup, the event happened, the boss is not happy, so this kinda has to work... According to this (Part 3): http://www.novell.com/coolsolutions/appnote/19386.html it is possible to trick LVM into starting anyway by creating a new pv with identical metadata to the failed disk, which will make the volume accessible, but of course leave giant holes in the file system. I have'n tried it yet, because it involves repairing (writing to) the file system which eliminates the possibility of trying other things if it fails. Now my question is: How does this setup actually allocate disk space for new data? Is it allocated linearly from beginning to end of PVs, in the order they were added to the vg? Is it striped somehow in order to increase performance/balance load? since this defective disk was added only later to an existing lvm2 vg and lv, containing a half-empty ext4, what are the chances that there was never any data written to the defective disk? In other words: what are the chances of recovering all my data, even without the defective disk, by just starting the volume group as-is? Am I about to go spend $1500 on having 250GB of empty space recovered when I send the defective disk in for repair? Is there a way to check without mounting the file system and opening the files, hoping they contain something other than zeros? (comparing addresses of used data blocks inside ext4 to address ranges that were on the missing pv, something like that, preferably easy to automate) I know bitwise-copying the entire lv into an image file before trying to repair the ext4 would probably be a good idea, but since this lv is very large and I just suffered major file system failure on several systems it is probably a luxury I don't have... Any suggestions?

  • Diff between $.ajaxSetup and $.ajax in jquery

    - by Deeptechtons
    title is a bit misleading but i would like to know internally (what happens during ajax request) when i execute Code 1 and Code 2 in turns Code 1 $.ajax({url:"1.aspx/HelloWorld",type:"GET",dataType:"json",contentType:"application/json"}); Code 2 $.ajaxSetup({ contentType: "application/json", dataType: "json" }); $.get("1.aspx/HelloWorld","",$.noop,"json"); i ask this because the method HelloWorld in page 1.aspx is executed correctly when run Code 1. But the seconds one refuses to invoke the pageMethod. I have set the ContentType and data as expected but the second request in Code 2 refuses to invoke the method does anyone have a reason for this ?

  • How to restore a dd overwritten disk partition?

    - by DairyKnight
    First of all, I admit I'm stupid and I didn't run proper backup of my data, but you know crap happens... So, I've used dd to overwrite the first 2GB of my 750GB NTFS partition with a FAT32 partition. I've run Photorec and EasyRecovery but all I can restore is the 2GB FAT32 partition and the files on that. Is there a way to "roll back" to the NTFS paritition, and recover - at least - some part of the 750GB data? Thanks.

  • Mounting GlusterFS share under www-data user

    - by Roman Newaza
    Problem: After directory is auto-mounted, Web Server has no write permissions to it. Question: How to auto-mount GlusterFS endpoint via /etc/fstab so that mount point belongs to www-data after it's mounted? For now, the mount point belongs to www-data, but after mounting it turns to root. # /etc/fstab foo.com:/st /st glusterfs defaults 0 0 Seams like I cannot define user / group as mount options for GlusterFS, at least I don't see it when man glusterfs. Thanks!

  • Declaring data types in SQLite

    - by dan04
    I'm familiar with how type affinity works in SQLite: You can declare column types as anything you want, and all that matters is whether the type name contains "INT", "CHAR", "FLOA", etc. But is there a commonly-used convention on what type names to use? For example, if you have an integer column, is it better to distinguish between TINYINT, SMALLINT, MEDIUMINT, and BIGINT, or just declare everything as INTEGER? So far, I've been using the following: INTEGER REAL CHAR(n) -- for strings with a known fixed with VARCHAR(n) -- for strings with a known maximum width TEXT -- for all other strings BLOB BOOLEAN DATE -- string in "YYYY-MM-DD" format TIME -- string in "HH:MM:SS" format TIMESTAMP -- string in "YYYY-MM-DD HH:MM:SS" format (Note that the last three are contrary to the type affinity.)

  • Validate a long type input

    - by Santiago
    I'm trying to validate that a user only enters a long value as input (long bigger than 0 actually). Compare and Range validator has DataTypeCheck for int values only. I was planning on using this class in a CustomValidator but then I would need to write both, client and server side validation code. Do you know of any other good way of doing this? Thanks!

  • Overloading the QDataStream << and >> operators for a user-defined type

    - by Alex Wood
    I have a an object I'd like to be able to read and write to/from a QDataStream. The header is as follows: class Compound { public: Compound(QString, QPixmap*, Ui::MainWindow*); void saveCurrentInfo(); void restoreSavedInfo(QGraphicsScene*); void setImage(QPixmap*); QString getName(); private: QString name, homeNotes, addNotes, expText; Ui::MainWindow *gui; QPixmap *image; struct NMRdata { QString hnmrText, cnmrText, hn_nmrText, hn_nmrNucl, notes; int hnmrFreqIndex, cnmrFreqIndex, hn_nmrFreqIndex, hnmrSolvIndex, cnmrSolvIndex, hn_nmrSolvIndex; }*nmr_data; struct IRdata { QString uvConc, lowResMethod, irText, uvText, lowResText, highResText, highResCalc, highResFnd, highResFrmla, notes; int irSolvIndex, uvSolvIndex; }*ir_data; struct PhysicalData { QString mpEdit, bpEdit, mpParensEdit, bpParensEdit, rfEdit, phyText, optAlpha, optConc, elemText, elemFrmla, notes; int phySolvIndex, optSolvIndex; }*physical_data; }; For all intensive purposes, the class just serves as an abstraction for a handful of QStrings and a QPixmap. Ideally, I would be able to write a QList to a QDataStream but I'm not exactly sure how to go about doing this. If operator overloading is a suitable solution, would writing code like friend QDataStream& operator << (QDataStream&,Compound) { ... } be a potential solution? I'm very open to suggestions! Please let me know if any further clarification is needed.

  • ImageView scale type not working in list activity

    - by Justin
    I have used ImageView's before and understand the different scale types that can be set... However I am having an incredibly difficult time trying to get an ImageView to scale properly in the row of a ListActivity or an ExpandableListActivity. I have tried setting the android:scaleType property to every single value but the image never scales down. I have set the min and max sizes as well and they don't seem to have any effect. I have done both of these things in both the XMl and in code to no avail... Does anyone have any ideas or perhaps a workaround? Thanks in advance!

  • How to temporarily replace one primitive type with another when compiling to different targets in c#

    - by Keith
    How to easily/quickly replace float's for doubles (for example) for compiling to two different targets using these two particular choices of primitive types? Discussion: I have a large amount of c# code under development that I need to compile to alternatively use float, double or decimals depending on the use case of the target assembly. Using something like “class MYNumber : Double” so that it is only necessary to change one line of code does not work as Double is sealed, and obviously there is no #define in C#. Peppering the code with #if #else statements is also not an option, there is just too much supporting Math operators/related code using these particular primitive types. I am at a loss on how to do this apparently simple task, thanks! Edit: Just a quick comment in relation to boxing mentioned in Kyles reply: Unfortunately I need to avoid boxing, mainly since float's are being chosen when maximum speed is required, and decimals when maximum accuracy is the priority (and taking the 20x+ performance hit is acceptable). Boxing would probably rules out decimals as a valid choice and defeat the purpose somewhat. Edit2: For reference, those suggesting generics as a possible answer to this question note that there are many issues which count generics out (at least for our needs). For an overview and further references see Using generics for calculations
