• Bad value for type timestamp on production server

  - by Juan Javaloyes

  I'm working with: seam 2.2.2 + hibernate + richfaces + jboss 5.1 + postgres I have an module which needs to load some data from the database. Easy. The problem is, on development it works fine, 100%, but when I deploy on my production server and try to get the data, an error rise: could not read column value from result set: fechahor9_504_; Bad value for type timestamp : [C@122e5cf SQL Error: 0, SQLState: 22007 Bad value for type timestamp : [C@122e5cf javax.persistence.PersistenceException: org.hibernate.exception.DataException: could not execute query [more errors] Caused by: org.postgresql.util.PSQLException: Bad value for type timestamp : [C@122e5cf at org.postgresql.jdbc2.TimestampUtils.loadCalendar(TimestampUtils.java:232) [more errors] Caused by: java.lang.NumberFormatException: Trailing junk on timestamp: '' at org.postgresql.jdbc2.TimestampUtils.loadCalendar(TimestampUtils.java:226) I can't understand why it works on my machine (development) and why not on production. Any clues? Anyone gone through the same problem? Is exactly the same compilation

  - by JVXR

  I have to display a graph with date on the X axis and Amt on the Y axis. There will be 8 lines (series) each with n months data. When I plot the graph I am sending in 6 months data for sure.( one line's data is shown below) [1251701950000, 34.50553] [1254294030000, 27.014463] [1256972350000, 26.7805] [1259567970000, 33.08871] [1262246430000, 51.987762] [1264924750000, 56.868233] However the graph shows up like this http://twitpic.com/1gbb7m The first months label is missing and last month is not aligned correctly, my flot js code is as follows $.plot($("#lgdGraphTab"),graphData, { xaxis: { mode: "time", timeformat: "%b-%y", monthNames: ["Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"], minTickSize: [1, "month"] }, yaxis : { tickSize: 5 }, series: { lines: { show: true , shadowSize:0}, points: { show: true } }, legend:{ container: $('#legendArea'), noColumns:8 }, clickable: true, hoverable: true });

• "Metadata information not found" while using EF4's POCO Template?

  - by ladenedge

  I just installed the POCO Template for EF4. I have a single entity in my model, AnnouncementText, and the T4 files seem to be properly generated. Attempting to access this new entity is throwing the following error when I access the auto-generated property MyObjectContext.AnnouncementTexts: InvalidOperationException: Mapping and metadata information could not be found for EntityType 'MyNamespace.AnnouncementText'. The properties on the AnnouncementText POCO seem to match up with the columns in the database, and I haven't changed any of the auto-generated code. The stack trace is: at System.Data.Objects.ObjectContext.GetTypeUsage(Type entityCLRType) at System.Data.Objects.ObjectContext.GetEntitySetForNameAndType(String entitySetName, Type entityCLRType, String exceptionParameterName) at System.Data.Objects.ObjectContext.CreateObjectSet[TEntity](String entitySetName) at MyNamespace.MyObjectContext.get_AnnouncementTexts() in C:\<snip>\MyObjectContext.Context.cs:line 65 at MyNamespace.Class1.Main() in C:\<snip>\Class1.cs:line 14 If I delete the .tt files from the solution and enable code generation on the model, I am able to access the property without issue. Here's my code, in case that might help: using (var context = new MyObjectContext()) foreach (var at in context.AnnouncementTexts) Console.WriteLine(at.Title); Any ideas on what might be wrong?

• Very large database, very small portion most being retrieved in real time

  - by ming yeow

  Hi folks, I have an interesting database problem. I have a DB that is 150GB in size. My memory buffer is 8GB. Most of my data is rarely being retrieved, or mainly being retrieved by backend processes. I would very much prefer to keep them around because some features require them. Some of it (namely some tables, and some identifiable parts of certain tables) are used very often in a user facing manner How can I make sure that the latter is always being kept in memory? (there is more than enough space for these) More info: We are on Ruby on rails. The database is MYSQL, our tables are stored using INNODB. We are sharding the data across 2 partitions. Because we are sharding it, we store most of our data using JSON blobs, while indexing only the primary keys

• Keeping the row in edit mode after saveRow in jqgrid

  - by Chirantan

  I want to be able to keep the row in edit mode even after calling saveRow() function in jQgrid. This is because I want to be able to validate the data being saved and remove the edit mode only when the data has passed its validations. I am aware of the succesfunc, which gets called after successful posting of data. I get the response handle too, however, manually calling the editRow(row_id); function does not seem to work. Is there anyway, I can keep the row in edit mode after calling saveRow?

• Embed SQL Password into Crystal Reports RPT file?

  - by codeulike

  We are experimenting with Crystal Reports viewers such as this one: http://www.thereportviewer.com/ ... which can actually re-connect to the data source and re-run a Crystal Reports RPT file with live data. However when running the report the viewer asks for a password to connect to the data source (in this case SQL Server). Does Crystal Reports have some way of embedding a connection password into a RPT file to avoid this? Or should I be using a System DSN from the Control Panel/ODBC thing to get around this? I figure someone else must have had this problem.

• Cannot iterate of a collection of Anonymous Types created from a LINQ Query in VB.NET

  - by Atari2600

  Ok everyone, I must be missing something here. Every LINQ example I have seen for VB.NET anonymous types claims I can do something like this: Dim Info As EnumerableRowCollection = pDataSet.Tables(0).AsEnumerable Dim Infos = From a In Info _ Select New With {.Prop1 = a("Prop1"), .Prop2 = a("Prop2"), .Prop3 = a("Prop3") } Now when I go to iterate through the collection(see example below), I get an error that says "Name "x" is not declared. For Each x in Infos ... Next It's like VB.NET doesn't understand that Infos is a collection of anonymous types created by LINQ and wants me to declare "x" as some type. (Wouldn't this defeat the purpose of an anonymous type?) I have added the references to System.Data.Linq and System.Data.DataSetExtensions to my project. Here is what I am importing with the class: Imports System.Linq Imports System.Linq.Enumerable Imports System.Linq.Queryable Imports System.Data.Linq Any ideas?

• how to bind datasouce to the labels and pass parameter in XtraReport ?

  - by ahmed

  There's something that I don't get it yet in Xtrareport. I have to bind the datasource at runtime and also I have to assign the datasource to the labels programatically. Binding data at runtime is fine ,(and here's my question)I did not get from any examples to how should I bind the datasource to the labels and how to pass the parameter(UserId) from runtime and how to call the report from a webform. For example, I have a table called "User" with 3 fields: UserId, Username and Password. In the report designer I place 3 labels. Then I have a webform where the user is entering the userID and pulling some data and I have a print button on that webform when the user clicks the print button the data should be displayed on the report of UserId..

• Cast error on SQLDataReader (entlib 5.0, asp.net 3.5, vb)

  - by Phil

  My site is using enterprise library v 5.0. Mainly the DAAB. Some functions such as executescalar, executedataset are working as expected. The problems appear when I start to use Readers I have this function in my includes class: Public Function AssignedDepartmentDetail(ByVal Did As Integer) As SqlDataReader Dim reader As SqlDataReader Dim Command As SqlCommand = db.GetSqlStringCommand("select seomthing from somewhere where something = @did") db.AddInParameter(Command, "@did", Data.DbType.Int32, Did) reader = db.ExecuteReader(Command) reader.Read() Return reader End Function This is called from my aspx.vb like so: reader = includes.AssignedDepartmentDetail(Did) If reader.HasRows Then TheModule = reader("templatefilename") PageID = reader("id") Else TheModule = "#" End If This gives the following error on db.ExecuteReader line: Unable to cast object of type 'Microsoft.Practices.EnterpriseLibrary.Data.RefCountingDataReader' to type 'System.Data.SqlClient.SqlDataReader'. Can anyone shed any light on how I go about getting this working. Will I always run into problems when dealing with readers via entlib?

• Drupal JSON POST from PhoneGap

  - by abritez

  I am trying to send a POST request to Drupal's Services module & JSON_Server module, however I am getting { "#error": true, "#data": "Invalid method " } Since PhoneGap runs html files from locally on the phone, should i need to worry about JSONP. The issue I have with that is that I must POST data, and JSONP only allows for GET. Any ideas would be helpful. Thanks! //SEND REQUEST AND CALLBACK FUNCTION var req; DrupalService.prototype.request = function(dataObject, callback){ req = false; var url = DRUPAL_JSON_URL; var params = "data="+dataObject; try { req = new XMLHttpRequest(); } catch(e) { req = false; } if(req) { req.onreadystatechange = function() {//Call a function when the state changes. if(req.readyState == 4 && req.status == 200) { console.log(" "+req.responseText); } } req.open("POST", url, false); req.send(params); } }

• [C#/WPF] Combo box Item source = ObservableCollection & I need a '-None-' dummy entry at the top

  - by James

  I have a combo box using an observable collection as a datasource and I want a "dummy" value of "None" as the first item in the box as it controls filters against other data sources. Other databound objects also use the same observable collection so adding a "None" value directly to the datasource is not possible as I dont want, for example, my datagrids having a "none" in them. Also I'd rather avoid filters to just remove the "none" value for those that do not use it, as I'd like the observable collection to direclty reflect the database data; if at all possible. I'd also like to avoid having one observable collection per databound control. What I'm really after is a was to put a, non data bound, first entry into a combobox while also having the item source pointed at an obervable collection. Thanks

• Android - Read PNG image without alpha and decode as ARGB_8888 Android

  - by loki666

  I try to read an image from sdcard (in emulator) and then create a Bitmap image with the "BitmapFactory.decodeByteArray" method. I set the options: options.inPrefferedConfig = Bitmap.Config.ARGB_8888 options.inDither = false Then I extract the pixels into a ByteBuffer. ByteBuffer buffer = ByteBuffer.allocateDirect(width*height*4) bitmap.copyPixelsToBuffer(buffer) I use this ByteBuffer then in the JNI to convert it into RGB format and want to calculate on it. But always I get false data - I test without modifying the ByteBuffer. Only thing I do is to put it into the native method into JNI. Then cast it into a unsigned char* and convert it back into a ByteBuffer before returning it back to Java. Before displaying the image I get data back with bitmap.copyPixelsFromBuffer( buffer ) But then it has wrong data in it. My Question is if this is because the image is internally converted into RGB 565 or what is wrong here? May anybody has an idea, it would be great!

• Object Oriented PHP Best Practices

  - by user270797

  Say I have a class which represents a person, a variable within that class would be $name. Previously, In my scripts I would create an instance of the object then set the name by just using: $object->name = "x"; However, I was told this was not best practice? That I should have a function set_name() or something similar like this: function set_name($name) { $this->name=$name; } is this correct? If in this example I want to insert a new "person" record into the db, how do I pass all the information about the person ie $name, $age, $address, $phone etc to the class in order to insert it, should I do: function set($data) { $this->name= $data['name']; $this->age = $data['age']; etc etc } Then send it an array? Would this be best practice? or could someone please recommend best practice?

• iPhone: How to Get Basic Authentication to HTTPS Web Service Using NSURLCredential

  - by ian1971

  I am trying to call an https web service (RESTful) using basic authentication. It works fine if I put the credentials in the url itself but I would rather add it to the request so that the password does not appear, for instance in an exception. I am using the following code: NSURLCredential *credential = [NSURLCredential credentialWithUser:@"myuser" password:@"mypassword" persistence:NSURLCredentialPersistenceForSession]; NSURLProtectionSpace *protectionSpace = [[NSURLProtectionSpace alloc] initWithHost:@"example.com" port:443 protocol:@"https" realm:nil authenticationMethod:NSURLAuthenticationMethodHTTPBasic]; [[NSURLCredentialStorage sharedCredentialStorage] setDefaultCredential:credential forProtectionSpace:protectionSpace]; NSURLConnection *theConnection = [NSURLConnection connectionWithRequest:theRequest delegate:self]; but it does not work. The didReceiveAuthenticationChallenge delegate method gets called and I can add a credential there but ideally I would send it with the request. Any ideas?

• Fiscal year handling strategies in database design

  - by Sapphire

  By fiscal year I mean all the data in the database (in all tables) that occurred in the particular year. Lets say that we are building an application that allows user to choose from different years. What way of implementing this would you prefer, and why: Separate fiscal year data based on multiple separate database instances (for example, on every fiscal year start you could create a new instance with no data) Have everything in one database, but with logic that automatically separates records from different years. Personally, I have "seen" both methods, and I would choose the second. The only argument I can think of for the first method is to have less records in case that these are really big databases - but still, you could "archive" old records by joining them in summaries or by some other way. What do you think?

• Issue reading packets from a pcap file. dpkt

  - by Chris

  I am running the following test script to try to read packets from a sample .pcap file I have downloaded. import socket import dpkt import sys pcapReader = dpkt.pcap.Reader(file("test1.pcap", "rb")) for ts, data in pcapReader: ether = dpkt.ethernet.Ethernet(data) if ether.type != dpkt.ethernet.ETH_TYPE_IP: raise ip = ether.data src = socket.inet_ntoa(ip.src) dst = socket.inet_ntoa(ip.dst) print "%s -> %s" % (src, dst) For some reason, this is not being interpreted properly. When running it, I get KeyError: 138 module body in test.py at line 4 function __init__ in pcap.py at line 105 Program exited. Why is this? What's wrong?

• WPF parent-child window: binding reference problem

  - by LukePet

  I have a WPF Window that open a modal child window to load some data. Both window have a own viewmodel, now I have this problem: after I close the child window it seems still running in background! To close the child window I set DialogResult from viewmodel command; now, if I create a new data and then I edit it from parent window (with the child window closed before), the child window still capture the property changed event for the properties previously bind. How can avoid this? I would clear every reference with data when I close modal window. Which is the best practise to do it?

• Excel VBA - How to copy/transpose multiple columns record into individual single row

  - by larry

  I'm working on data migration, need some help on doing a macro to copy/transpose multiple columns record into individual single row. There are also a "tag" in the first row, which indicates the columns that should not be included in the copy/transpose. From: Tag x Name Jan Feb Mar Apr Larry 2 20 34 56 Harry 3 45 77 88 Marry 5 66 44 33 To: Larry Jan 2 Larry Feb 20 Larry Apr 56 Harry Jan 3 Harry Feb 45 Harry Apr 88 Marry Jan 5 Marry Feb 66 Marry Apr 33 The "Mar" data was omitted due to there's a tag (X) above it. The data might be near hundred columns (few years), and some of the months need to be omitted. Any expert able to help on this? I had been spending whole day cracking my head on this. Worse come to worse I might have to manually copy and paste, that would probably took me a decade.

• SOAP Web Service method naming conventions

  - by dbguy

  Consider a Web Service (e.g. SOAP-based) that has an operation which accepts a bulk of data from the client. From the server's point of view it is receiving data, but from the client's point of view it's sending data. How should that operation be named? The options are ImportData ExportData / SendData Is there a de facto standard for naming these things? How do web services usually name these? Thank you for your opinions.

• Reporting Services: Two Tables One Sum

  - by Neomoon

  My report is as follows: One table provides financial information with sums at the group footer (Grouping is called "StockTable_Shipped"). The group is controlled by a boolean value (1=shows shipped data, 0 = shows received data) The second table is a variance report for data that has been shipped (boolean value of 1) and has a sum at the bottom of the table. My ultimate goal is to take the sum from table1 where shipped=1 and subtract it from the variance sum from table2. This will be placed in a textbox at the bottom of the report. I understand if this sounds confusing but I would be more then happy to provide more information.

• Using npgsql with SSIS

  - by Flash

  Hi, I am using npgsql as the ADO.NET provider in SSIS to connect to Postgres and create some workflows. I am able to connect to postgres but am unable to use the "Table or view" data access mode to list the tables and views. I have to resort to using "SQL command" data access mode. For the "table or view" access mode, the log shows that the last call is GetDataSourceInformation and it returns successfully. After that there is a close connection. Has anyone successfully used "Table or view" data access mode using npgsql? Thanks, Flash

• JSONP callback method is not defined

  - by Micah

  I'm trying to get a jsonp callback working using jquery within a greasemonkey script. Here's my jquery: $.ajax({ url: "http://mydomain.com/MyWebService?callback=?", data: { authkey: "temphash" }, type: "get", dataType: "json", cache: false, success: function(data) { console.log(data); } }); in my webservice (asp.net) I'm returning the response with a content type of application/javascript. The response the server is actually sending back is: jsonp1276109314602({"message":"I'm getting tired of this not working"}) The jsonp1276109314602 method name is being randomly generated by jquery, and I'm grabbing it with Request.QueryString["callback"] However my success function is never called and the firebug console gives me an error saying jsonp1276109314602 is not defined. What am I doing wrong?

• Delphi 2010 Professional and remote database access

  - by Kico Lobo

  Hi, When looking for which version of Delphi 2010 to buy, we found the following limitation on the professional one: Delphi 2010 Professional is designed for developers building high-performance desktop GUI and touch-screen applications with (or without) embedded and local database persistence. What does this really mean? Does this mean that we'll only face this restriction if we choose to use the native vcl components for database access we'll face this restriction. And what if we choose to use ADO components instead of those? In this case, how can Delphi avoid us to access remote database servers? Did anyone here ever tried this? Going even further: if we choose to use a database like Firebird, which is just one file, and used a network mapped drive. Could we be facing the same limitation? Supposing we opt for ADO, what will be the main consequences?
