• Building a service for a Drupal site to duplicate a node to another Drupal site in a multi-site setu

  - by EricP

  I'm trying to set up one of my Drupal sites to push a node to another Drupal site in a multi-site configuration. It looks like I need to do this with services somehow, but I can't find any tutorials out there and I need at least to be pointed in the right direction. What I believe I need is set up Services on the receiving site to accept a call from the sending site which will be sending the node object via Json or serialized PHP using a Key that was set up on the receiving site. Can anyone show me an example of this working or give me some insight? thanks

• Can't read output of httpservice

  - by tag

  I have an HTTPservice that uses id="myhttp" url="site.com/script.php" method="POST" resultFormat="xml" script.php returns $output = '' . $worked . ''; echo $output; Problem is when I try to read worked, it tells me the variable worked is not there event.result.worked myhttp.lastResult.worked The only thing that works is using toString() myhttp.lastResult.toString() or event.result.toString() What am I doing wrong? I plan to add other variables to the output time, so need to access each time and worked separately. I may also need to return multiple responses each with their own worked and time values. How do I do that. I was thinking to not use XML. Is there a more lightweight option. Flex shows I have the following options: array e4x flashvars object text xml

• ASP.NET/VB/SQL: trying to insert data, getting error "no value given for required parameters"

  - by Sara

  I am pretty sure this is a basic syntax error, I am new at this and basically figuring things out by trial and error... I am trying to insert data from textboxes into an Access database, where the primary key fields in tableCourse are prefix and course_number. It keeps giving me the "no value given for one or more required parameters" error. Here is my codebehind: Protected Sub Wizard1_FinishButtonClick(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.WizardNavigationEventArgs) Handles Wizard1.FinishButtonClick 'Collect Data Dim myDept = txtDept.Text Dim myFirst = txtFirstName.Text Dim myLast = txtLastName.Text Dim myPrefix = txtCoursePrefix.Text Dim myNum = txtCourseNum.Text 'Define Connection Dim myConn As New OleDbConnection myConn.ConnectionString = AccessDataSource1.ConnectionString 'Create commands Dim myIns1 As New OleDbCommand("INSERT INTO tableCourse (department, name_first, name_last, prefix, course_number) VALUES (@myDept, @myFirst, @myLast, @myPrefix, @myNum)", myConn) 'Execute the commands myConn.Open() myIns1.ExecuteNonQuery() End Sub

• Can you solve my odd Sharepoint CSS cache / customising problem?

  - by Aidan

  I have a weird situation with my sharepoint css. It is deployed as part of a .wsp solution and up until now everything has been fine. The farm it deploys too has a couple of webfront ends and a single apps server and SQL box. The symptom is that if I deploy the solution, then use a webbrowser to view the page it has no styles, and if I access the .css directly I see the first 100 or so bytes of the .css. However if I go into sharepoint designer and look at the file it is looks fine, and if I check it out and publish it (customising the file but not actually changing anything in it) then the website works fine and the css downloads completely. There is some fairly complex caching on the servers Disk based and object caches. as far as I can tell I have cleared these (and an issreset should clear them anyway... shouldn't it?) I have used this tool to clear the blobcache from the whole farm http://blobcachefarmflush.codeplex.com/

• Data-only static libraries with GCC

  - by regularfry

  How can I make static libraries with only binary data, that is without any object code, and make that data available to a C program? Here's the build process and simplified code I'm trying to make work: ./datafile: abcdefghij Makefile: libdatafile.a: ar [magic] datafile main: libdatafile.a gcc main.c libdatafile.a -o main main.c: #define TEXTPTR [more magic] int main(){ char mystring[11]; memset(mystring, '\0', 11); memcpy(TEXTPTR, mystring, 10); puts(mystring); puts(mystring); return 0; } The output I'm expecting from running main is, of course: abcdefghijabcdefghij My question is: what should [magic] and [more magic] be?

• I'd like to preview a Word document on form.

  - by Tychumsempir

  I'm writing a VB program that fills in values within a word document. I'm utilizing the Microsoft Word 12.0 Object Library as a Reference. I'd like to provide a scrollable preview pane to my user that is within the form he or she is using. It would be even cooler if the user could edit the document through this pane. I've done Interop extensively, so I'm well aware of how to write and edit a Word document. I just want to put it into a frame and preview it. I'll probably try to select around the document based on what is changing as the user provides input so they can see what's being changed and where. Thoughts? Thanks

• MVC Custom Model Binder Binding Multiple Values

  - by BMD86

  Hello everyone, I have a scenario in which I have multiple sources to bind to my model. For one, I have a view tied to a strongly-typed model, but this scenario also entails posting data to this view from a 3rd party site. Essentially, what I believe I am after in the custom model binding is to investigate the form values in the Request object within HTTPContext to see if I have a field such as "postedFirstName". If so, I want to bind that value instead of the textbox "FirstName" in my view. I've done a good bit of searching but have not find anything that exactly addresses such a scenario. This link was close, I thought, but not quite: http://stackoverflow.com/questions/970335/asp-net-mvc-mixing-custom-and-default-model-binding Any input is greatly appreciated!

• Python: Access members of a set

  - by emu

  Say I have a set myset of custom objects that may be equal although their references are different (a == b and a is not b). Now if I add(a) to the set, Python correctly assumes that a in myset and b in myset even though there is only len(myset) == 1 object in the set. That is clear. But is it now possible to extract the value of a somehow out from the set, using b only? Suppose that the objects are mutable and I want to change them both, having forgotten the direct reference to a. Put differently, I am looking for the myset[b] operation, which would return exactly the member a of the set. It seems to me that the type set cannot do this (faster than iterating through all its members). If so, is there at least an effective work-around?

• db2 jdbc driver does not release table locks

  - by as

  situation: We have a web service running on tomcat accessing DB2 database on AS400, we are using JTOPEN drivers for JNDI connections handled by tomcat. For handling transactions and access to database we are using Spring. For each select system takes JDBC connection from JNDI (i.e. from connection pool), does selection, and in the end it closes ResultSet, Statement and releases Connection in that order. That passes fine, shared lock on table dissappears. When we want to do update the same way as we did with select (exception on ResultSet object, we don't have one in such situation), after releasing Connection to JNDI lock on table stays. If we put maxIdle=0 for number of connections in JNDI configuration, this problem disappears, but this degrades performances, we have cca 100 users online on that service, we need few connections to be alive in pool. What do you suggest?

• What is the most elegant way to access current_user from the models? or why is it a bad idea?

  - by TheLindyHop

  So, I've implemented some permissions between my users and the objects the users modify.. and I would like to lessen the coupling between the views/controllers with the models (calling said permissions). To do that, I had an idea: Implementing some of the permission functionality in the before_save / before_create / before_destroy callbacks. But since the permissions are tied to users (current_user.can_do_whatever?), I didn't know what to do. This idea may even increase coupling, as current_user is specifically controller-level. The reason why I initially wanted to do this is: All over my controllers, I'm having to check if a user has the ability to save / create / destroy. So, why not just return false upon save / create / destroy like rails' .save already does, and add an error to the model object and return false, just like rails' validations? Idk, is this good or bad? is there a better way to do this?

• How do I calculate someone's age in Java?

  - by nojevive

  I want to return an age in years as an int in a Java method. What I have now is the following where getBirthDate() returns a Date object (with the birth date ;-)): public int getAge() { long ageInMillis = new Date().getTime() - getBirthDate().getTime(); Date age = new Date(ageInMillis); return age.getYear(); } But since getYear() is deprecated I'm wondering if there is a better way to do this? I'm not even sure this works correctly, since I have no unit tests in place (yet).

• Python: How to get a value of datetime.today() that is "timezone aware"?

  - by mindthief

  Hi, I am trying to subtract one date value from the value of datetime.today() to calculate how long ago something was. But it complains: TypeError: can't subtract offset-naive and offset-aware datetimes The value datetime.today() doesn't seem to be "timezone aware", while my other date value is. How do I get a value of datetime.today() that is timezone aware? Right now it's giving me the time in local time, which happens to be PST, i.e. UTC-8hrs. Worst case, is there a way I can manually enter a timezone value into the datetime object returned by datetime.today() and set it to UTC-8? Of course, the ideal solution would be for it to automatically know the timezone. Thanks!

• Many-to-one relationship in SQLAlchemy

  - by Arrieta

  This is a beginner-level question. I have a catalog of mtypes: mtype_id name 1 'mtype1' 2 'mtype2' [etc] and a catalog of Objects, which must have an associated mtype: obj_id mtype_id name 1 1 'obj1' 2 1 'obj2' 3 2 'obj3' [etc] I am trying to do this in SQLAlchemy by creating the following schemas: mtypes_table = Table('mtypes', metadata, Column('mtype_id', Integer, primary_key=True), Column('name', String(50), nullable=False, unique=True), ) objs_table = Table('objects', metadata, Column('obj_id', Integer, primary_key=True), Column('mtype_id', None, ForeignKey('mtypes.mtype_id')), Column('name', String(50), nullable=False, unique=True), ) mapper(MType, mtypes_table) mapper(MyObject, objs_table, properties={'mtype':Relationship(MType, backref='objs', cascade="all, delete-orphan")} ) When I try to add a simple element like: mtype1 = MType('mtype1') obj1 = MyObject('obj1') obj1.mtype=mtype1 session.add(obj1) I get the error: AttributeError: 'NoneType' object has no attribute 'cascade_iterator' Any ideas?

• Can an application's Service ever run in a different process?

  - by kpdvx

  If an application begins a Service via bindService or startService, will this Service object ever run from a process different from that of the application? I ask because many Android example projects begin a service and communicate to them using IPC which seems wholly unnecessary considering that, according to the Android Service documentation, "... services, like other application objects, run in the main thread of their hosting process." IPC, AIDL, and the IBinder interface only seem useful if connecting to a Service started by an application other than your own. Is this a correct or fair understanding?

• Design question - loading info from DB

  - by eriks

  I need to build a class that will represent a row in some table in DB (lets say the table is 'Subscriber' and so is the class). I can have the class Subscriber which constructor receives the Objectkey of subscriber, retrieves info from DB and initializes its members. I add another class - SubscriberLoader which have a static method 'LoadSubscriber'. This method will receive the subscriber objectkey, retrieve info from DB, crate a Subscriber object and initialize its members. Subscriber constructor will be private and SubscirberLoader will be friend class of Subscriber - this way, client could build a Subscriber only using the loader. which of the two in better? any other suggestions?

• Getting ListView values into a string array?

  I have a ListView control set up in details mode, and on a button press I would like to retrieve all column values from that row in the ListView. This is my code so far: Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click Dim items As ListView.SelectedListViewItemCollection = _ Me.ManageList.SelectedItems Dim item As ListViewItem Dim values(0 To 4) As String Dim i As Integer = 0 For Each item In items values(i) = item.SubItems(1).Text i = i + 1 Next End Sub But values just comes out as an empty array. Any ideas? I just want the values array to be filled with the data of that ListView row. Cheers.

Senior.first.age #=> 56 Thanks!

• How to access YAML sublevel item in a nested variable?

  Getting the error: You have a nil object when you didn't expect it! You might have expected an instance of Array. The error occurred while evaluating nil.[] APP_CONFIG are loading fine. account_type = 'sample' allowed = APP_CONFIG['account']["#{account_type}"]['highlight'] Error points to 'allowed' variable line.

Any doubts, please ask me. Thanks!

• ASP.NET web services leak memory when (de)serializing disposable objects?

  - by Serilla

  In the following two cases, if Customer is disposable (implementing IDisposable), I believe it will not be disposed by ASP.NET, potentially being the cause of a memory leak: [WebMethod] public Customer FetchCustomer(int id) { return new Customer(id); } [WebMethod] public void SaveCustomer(Customer value) { // save it } This flaw applies to any IDisposable object. So returning a DataSet from a ASP.NET web service, for example, will also result in a memory leak - the DataSet will not be disposed. In my case, Customer opened a database connection which was cleaned up in Dispose - except Dispose was never called resulting in loads of unclosed database connections. I realise there a whole bunch of bad practices being followed here (its only an example anyway), but the point is that ASP.NET - the (de)serializer - is responsible for disposing these objects, so why doesn't it? This is an issue I was aware of for a while, but never got to the bottom of. I'm hoping somebody can confirm what I have found, and perhaps explain if there is a way of dealing with it.

• What's the best way to set cursor/caret position?

  - by Daniel Bachhuber

  If I'm inserting content into a textarea that TinyMCE has co-opted, what's the best way to set the position of the cursor/caret? I'm using tinyMCE.execCommand("mceInsertRawHTML", false, content); to insert the content, and I'd like set the cursor position to the end of the content. Both document.selection and myField.selectionStart won't work for this, and I feel as though this is going to be supported by TinyMCE (through something I can't find on their forum) or it's going to be a really ugly hack. Later: It gets better; I just figured out that, when you load TinyMCE in WordPress, it loads the entire editor in an embedded iframe. Later (2): I can use document.getElementById('content_ifr').contentDocument.getSelection(); to get the selection as a string, but not a Selection Object that I can use getRangeAt(0) on. Making progress little by little.
