• Microsoft.Biztalk.explorerom.dll reference in asp.net application resulting system.nullreferenceexce

  - by sheetal.oza

  Hi, I have a asp.net application in order to start/stop applications and ports of Biztalk server 2006 r2. I have used "Microsoft.Biztalk.explorerom.dll (C:/Program Files/Biztalk Server 2006/Developer tool) " to achieve this. This is working fine on development machine since biz talk server is installed on local machine. But in the production environment (asp.net web server ,windows 2003 and iis 6.0)...this give System.nullreferenceexception (object reference not set..) at BtsCatalogExplorer explorer = (BtsCatalogExplorer)myGroup.CreateInstance(typeof(BtsCatalogExplorer)) my biztalk server and sql server are on two different box. In my setup (asp.net web application)..adding Microsoft.Biztalk.explorerom.dll and Microsoft.Biztalk.Applicationdeployment.engine.dll to GAC. But still no luck. Do i need to install biz talk server on my local machine even though I am connecting to different biz talk server?? And help is appreciated...

  - by Wondering

  Dear All, I have a grid view and I want to implement Pagination functionality.This is working fine. protected DataSet FillDataSet() { string source = "Database=GridTest;Server=Localhost;Trusted_Connection=yes"; con = new SqlConnection(source); cmd = new SqlCommand("proc_mygrid", con); ds = new DataSet(); da = new SqlDataAdapter(cmd); da.Fill(ds); GridView1.DataSource = ds; GridView1.DataBind(); return ds; } protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e) { int newPagenumber = e.NewPageIndex; GridView1.PageIndex = newPagenumber; GridView1.DataSource = FillDataSet(); GridView1.DataBind(); } But the problem is for each pagination I have to call FillDataSet(); Is there any way to stop that.Any other coding approach? Thanks.

• DDD - Validation of unique constraint

  - by W3Max

  In DDD you should never let your entities enter an invalid state. That being said, how do you handle the validation of a unique constraint? The creation of an entity is not a real problem. But let say you have an entity that must have a unique name and there is a thousand instances of this entity type - they are not in memory but stored in a database. Now let say you want to rename an instance. You can't just use a setter... the object could enter an invalid state - you have to validate against the database. How do you handle this scenario in a web environment?

• ServletContext getResource not working

  - by David

  I'm trying to use ServletContext.getResource to retrieve a java.net.url reference to an image file (which I will then include in a PDF library using iText). When I use ServletContext.getRealPath("picture.jpg"), I get back a string URL. However, getResource always returns null. Example 1: String picture = ServletContext.getRealPath("picture.jpg"); // picture contains a non-null String with the correct path URL pictureURL = ServletContext.getResource(picture); // pictureURL is always null Example 2: URL pictureURL = ServletContext.getResource("picture.jpg"); // pictureURL is always null So what is the correct way to build a java.net.URL object pointing to a file in my webapps folder? Why does getRealPath work but not getResource? In case it helps at all, here is my folder structure webapps - mySite - picture.jpg Does my picture need to be stored in either WEB-INF or WEB-INF/classes to be read by getResource?

• C# winforms: DataSet with multiple levels of related tables

  - by Jake

  Hi, I am trying to use DataSet and DataAdapter to "filter" and "navigate" DataRows in DataTables. THE SITUATION: I have multiple logical objects, e.g. Car, Door and Hinge. I am loading a Form which will display complete Car information including each Door and their respective Hinges. In this senario, The form should display info for 1 car, 4 doors and 2 hinges for each door. Is it possible to use a SINGLE DataSet to navigate this Data? i.e. 1 DataRow in car_table, 4 DataRow in door_table and 8 DataRow in hinge_table, and still be able to navigate correctly between the different object and their relations? AND, able to DataAdapter.Update() easily? I have read about DataRelation but don't really understand how to use it. Not sure if it is the correct direction for my problem. Appreciate any advise. Thanks!

• iPad UIColor Saturation Issues

  - by Carter Allen

  I am trying to draw a UIColor on the screen of a view-based app, and I am trying to do so using HSB. It is absolutely necessary for me to use HSB in this case. I can create a UIColor object with any S value from 0.0f to 0.75f, but past that the numerical changes have no effect on the actual saturation displayed. I need it to be 1.0f, but it is still using 0.75f. Any ideas on why it is doing that, and how I can make it work?

• How do you create a unit-testing stub for an interface containing a read-only member?

  - by Robert Harvey

  I am writing some unit tests for an extension method I have written on IPrincipal. To assist, I have created a couple of helper classes (some code for not-implemented members of the interfaces has been omitted for brevity): public class IPrincipalStub : IPrincipal { private IIdentity identityStub = new IIdentityStub(); public IIdentity Identity { get { return identityStub } set { identityStub = value } } } public class IIdentityStub : IIdentity { public string Name { get; set; } } However, the Name property in the IIdentity interface is read-only (the IIDentity interface specifies a getter but not a setter for the Name property). How can I set the Name property in my stub object for testing purposes if the interface has defined it as a read-only property?

• Number of lines in csv.DictReader

  - by Alan Harris-Reid

  Hi there, I have a csv DictReader object (using Python 3.1), but I would like to know the number of lines/rows contained in the reader before I iterate through it. Something like as follows... myreader = csv.DictReader(open('myFile.csv', newline='')) totalrows = ? rowcount = 0 for row in myreader: rowcount +=1 print("Row %d/%d" % (rowcount,totalrows)) I know I could get the total by iterating through the reader, but then I couldn't run the 'for' loop. I could iterate through a copy of the reader, but I cannot find how to copy an iterator. I could also use totalrows = len(open('myFile.csv').readlines()) but that seems an unnecessary re-opening of the file. I would rather get the count from the DictReader if possible. Any help would be appreciated. Alan

• Functional data structures in C++

  - by drg

  Does anyone know of a C++ data structure library providing functional (a.k.a. immutable, or "persistent" in the FP sense) equivalents of the familiar STL structures? By "functional" I mean that the objects themselves are immutable, while modifications to those objects return new objects sharing the same internals as the parent object where appropriate. Ideally, such a library would resemble STL, and would work well with Boost.Phoenix (caveat- I haven't actually used Phoenix, but as far as I can tell it provides many algorithms but no data structures, unless a lazily-computed change to an existing data structure counts - does it?)

• Javascript string to Date conversion - simple?

  - by Mark White

  Hi all, Yesterday I managed to solve this, then lost a day's work due to the death of a HD. Now I cannot remember what I did to fix it, but I know it can be done. Input: string date in the format 'm/d/yy', eg '12/25/10', or '4/1/10' (1st April) Output - Date object I'm working with date.js and date.format.js so have Date.fromString() and Date.format() avaiable. But trying multiple combinations is not giving me what I need. IF the date were 'mm/dd/yy' then it's simple. But I'm using jquery.datepicker.js which outputs in 'm/d/yy' and I don't want to change this much I know this conversion can be done. After a 22 hour day... I need help. Thanks. Mark...

• Not able to capture Enter key in WinForms text box

  - by Michael Hermes

  When the user is entering a number into a text box, I would like them to be able to press Enter and simulate pressing an Update button elsewhere on the form. I have looked this up several places online, and this seems to be the code I want, but it's not working. When data has been put in the text box and Enter is pressed, all I get is a ding. What am I doing wrong? (Visual Studio 2008) private void tbxMod_KeyDown(object sender, KeyEventArgs e) { if (e.KeyCode == Keys.Enter) { btnMod.PerformClick(); } }

• How do i handle jcupload and no flash?

  - by acidzombie24

  I am using http://www.jcupload.com/ (basic) to upload files. I am considering having a friend write a more custom version or to do magic with ajax; so the solution should be able to work without that. With jcupload i include css, a script and write <div id="jcupload_content"></div> in my html and i am done. Problem is, with no flash i get an object box. Instead i would like is an iframe or a html form to upload the file. How do i do this? Should i detect flash from javascript and overload the div myself if no flash is available? How do i detect if flash is available? with jquery i know i can write something like $('#jcupload_content').innerHtml = blah; How do i handle the flash part?

• Get a tableview insertRowsAtIndexPaths to accept indexOfObject?

  - by Emil

  Hey. I have a code snippet that looks like this: [tableView beginUpdates]; [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationLeft]; [tableView insertRowsAtIndexPaths:[NSArray arrayWithObject:[array indexOfObject:[array objectAtIndex:indexPath.row]]] withRowAnimation:UITableViewRowAnimationLeft]; [tableView endUpdates]; [tableView reloadData]; It gets executed when a user clicks on an accessory. The first part is only there to provide a smooth animation, and does not really matter, as the tableView is reloaded milliseconds later, but as I said, it's there to provide an animation. It is supposed to move a selected object from its current indexPath to the value from an array at the same indexPath. Obviously, this code does not work, so I just want to know what can be done to fix it? PS: I get a warning when compiling, too. The usual "passing argument 1 of 'arrayWithObject:' makes pointer from integer without a cast..." (line 3)

• Using a Loader for a string of QML

  - by Robbert

  In Qt 5.3 I've been using the Loader QML element for loading screens. Now I'm trying to load a string of QML dynamically. Qt.createQmlObject enables me to do so, but I can't seem to get the Loader element to play along. Seems like Loader only takes a URL (QUrl) or component (QQmlComponent), but Qt.createQmlObject creates an object (QObject). I'm new to QML, but from my understanding components are reusable elements, similar to classes, and objects are the instances of those classes. I thus can't seem to wrap my head around why Loader wouldn't work with objects. How can I show a loading screen while (asynchronously) parsing and initializing a string of QML? Example QML code: Item { Rectangle {id: content} Loader {id: loader} Component.onCompleted: { var obj = Qt.createQmlObject('import QtQuick 2.3; Rectangle {}', content); loader.source = obj; // Throws error. } }

• How do I detect the environment in Salesforce?

  - by Craig Harris

  I am integrating our back end systems with Salesforce using the web services. I have production and stage environments running on different URLs. I need to be able to have the endpoint of the web service call be different depending on whether the code is running in the production or sandbox Salesforce instance. How do I detect the environment. Currently I am considering looking up a user to see if there user name ends in 'devsandbox' as I have been unable to identify a system object that I can query to get the environment. Further clarification: The location I need to determine this is within the Apex code that is invoked when I select a button in Salesforce. My custom controller needs to know if it running in the production or sandbox Salesforce environment.

• Using attribute text value in AngularJS directive

  - by C1pher

  Using a YouTube tutorial created by John Lindquist, I was able to create a directive using a template. See fiddle: http://jsfiddle.net/37PSs/ Now, I want to use the value of the attribute as a variable to a function call. Something like this: html: <hello-world name="World"></hello-world> javascript - directive: template: '<span>myFunction({{name}})</span>' javascript - myFunction(theirName): return ("Hello, " + String(theirName) + "!"); The closest I've been able to get is passing an [object Window] to my function.

• Joda-Time: Period to string

  - by tt

  I'm using the Joda-Time library with Java. I'm having some difficulty trying to turn a Period object to a string in the format of "x days, x hours, x minutes". These Period objects are first created by adding an amount of seconds to them (they are serialized to XML as seconds and then recreated from them). If I simply use the getHours() etc. methods in them, all I get is zero and the total amount of seconds with getSeconds. How can I make Joda calculate the seconds into the respective fields, like days, hours, etc...?

• JavaScript replace with callback - performance question

  - by Tomalak

  In JavaScript, you can define a callback handler in regex string replace operations: str.replace(/str[123]|etc/, replaceCallback); Imagine you have a lookup object of strings and replacements. var lookup = {"str1": "repl1", "str2": "repl2", "str3": "repl3", "etc": "etc" }; and this callback function: var replaceCallback = function(match) { if (lookup[match]) return lookup[match]; else return match; } How would you assess the performance of the above callback? Are there solid ways to improve it? Would if (match in lookup) //.... or even return lookup[match] | match; lead to opportunities for the JS compiler to optimize, or is it all the same thing?

• Communicating between PHP and Java using ActiveMQ/Stomp

  - by scompt.com

  Background I have two services that need to communicate with each other over a message queue. One is a legacy service written in PHP and the other is in Java. Sooner than later, the PHP service will be rewritten in Java. The current way they communicate with each other is to write to a shared database, which the other service polls. This is what I'm trying to get away from and replace with a message queue. Problem The communication I'm working on right now is from the PHP service to the Java service. It needs to send a relatively complex object (strings and and integers and lists and maps of strings and integers). Ideally, the solution would be workable in PHP and ideal in Java, as that's going to be the legacy of this project. Possible Solutions 1.

• How to send JSON request to service with parameters in Objective-C

  - by user1323884

  I'm creating a iPhone app, and im trying to figure out how to create a JSON request to the webservice that contains parameters. In Java this would look like this HashMap<String, String> headers = new HashMap<String, String>(); JSONObject json = new JSONObject(); json.put("nid", null); json.put("vocab", null); json.put("inturl", testoverview); json.put("mail", username); // [email protected] json.put("md5pw", password); // donkeykong headers.put("X-FBR-App", json.toString()); The header has to contain a JSON object and "X-FBR-App" before the service recognizes the request. How would this be implemented in Objective-C ?
