  • avoid textarea rows/cols error?

    - by acidzombie24
    I am using a few page validation tools one problem i have is they tell me textarea must have rows and cols attribute. If i am setting this in CSS or using display:none (and using it to hold raw text data) can i do something to skip? it seems like the only answer is rows="0" cols="0" each time i use it. But i have a feeling that is not a good solution.

  • Recursive templates: compilation error under g++

    - by Johannes
    Hi, I am trying to use templates recursively to define (at compile-time) a d-tuple of doubles. The code below compiles fine with Visual Studio 2010, but g++ fails and complains that it "cannot call constructor 'point<1::point' directly". Could anyone please shed some light on what is going on here? Many thanks, Jo #include <iostream> #include <utility> using namespace std; template <const int N> class point { private: pair<double, point<N-1> > coordPointPair; public: point() { coordPointPair.first = 0; coordPointPair.second.point<N-1>::point(); } }; template<> class point<1> { private: double coord; public: point() { coord= 0; } }; int main() { point<5> myPoint; return 0; }

  • jar dependencies in android- no class definition found exception

    - by Dave.B
    I'm trying to use the gdata java client library on android and have managed a decent hack to get it working. However because the jar for gdata had some package discrepancies with android I had to import the source into my project. This source is dependent on the JavaMail API and the JavaBeans Activation Framework as specified here. My issue is that the JavaMail jar throws a class definition not found when seeking a class which is in the Activation Framework jar. A stack trace is listed below. I am working in Eclipse and have both jars in a lib folder and added to my build path. I'm not very experienced dealing with jars in a situation like this so any help or insight would be appreciated. 03-29 09:55:26.204: ERROR/AndroidRuntime(331): Uncaught handler: thread AsyncTask #3 exiting due to uncaught exception 03-29 09:55:26.215: ERROR/AndroidRuntime(331): java.lang.RuntimeException: An error occured while executing doInBackground() 03-29 09:55:26.215: ERROR/AndroidRuntime(331): at android.os.AsyncTask$3.done(AsyncTask.java:200) 03-29 09:55:26.215: ERROR/AndroidRuntime(331): at java.util.concurrent.FutureTask$Sync.innerSetException(FutureTask.java:273) 03-29 09:55:26.215: ERROR/AndroidRuntime(331): at java.util.concurrent.FutureTask.setException(FutureTask.java:124) 03-29 09:55:26.215: ERROR/AndroidRuntime(331): at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:307) 03-29 09:55:26.215: ERROR/AndroidRuntime(331): at java.util.concurrent.FutureTask.run(FutureTask.java:137) 03-29 09:55:26.215: ERROR/AndroidRuntime(331): at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1068) 03-29 09:55:26.215: ERROR/AndroidRuntime(331): at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:561) 03-29 09:55:26.215: ERROR/AndroidRuntime(331): at java.lang.Thread.run(Thread.java:1096) 03-29 09:55:26.215: ERROR/AndroidRuntime(331): Caused by: java.lang.NoClassDefFoundError: javax.activation.DataHandler 03-29 09:55:26.215: ERROR/AndroidRuntime(331): at javax.mail.internet.MimeBodyPart.setContent(MimeBodyPart.java:684) 03-29 09:55:26.215: ERROR/AndroidRuntime(331): at com.google.gdata.data.media.MediaBodyPart.<init>(MediaBodyPart.java:95) 03-29 09:55:26.215: ERROR/AndroidRuntime(331): at com.google.gdata.data.media.MediaMultipart.<init>(MediaMultipart.java:126) 03-29 09:55:26.215: ERROR/AndroidRuntime(331): at com.google.gdata.client.media.MediaService.insert(MediaService.java:382) 03-29 09:55:26.215: ERROR/AndroidRuntime(331): at android.os.AsyncTask$2.call(AsyncTask.java:185) 03-29 09:55:26.215: ERROR/AndroidRuntime(331): at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:305)

  • static const C++ class member initialized gives a duplicate symbol error when linking

    - by Petruza
    I have a class which has a static const array, it has to be initialized outside the class: class foo{ static const int array[3]; }; const int foo::array[3] = { 1, 2, 3 }; But then I get a duplicate symbol foo::array in foo.o and main.o foo.o hold the foo class, and main.o holds main() and uses instances of foo. How can I share this static const array between all instances of foo? I mean, that's the idea of a static member.

  • error while updating a database in ASP.NET

    - by Viredae
    I am having trouble updating an SQL database, the problem is not that it doesn't update at all, but that particular parameters are being updated while the others are not. here is the code for updating the parameters: string EditRequest = "UPDATE Requests SET Description = @Desc, BJustif = @Justif, Priority = @Priority, Requested_System = @Requested, Request_Status = @Stat WHERE"; EditRequest += " Req_ID=@ID"; SqlConnection Submit_conn = new SqlConnection(WebConfigurationManager.ConnectionStrings["DBConn"].ConnectionString); SqlCommand Submit_comm = new SqlCommand(EditRequest, Submit_conn); Submit_comm.Parameters.AddWithValue("@ID", Request.QueryString["reqid"]); Submit_comm.Parameters.AddWithValue("@Desc", DescBox.Text); Submit_comm.Parameters.AddWithValue("@Justif", JustifBox.Text); Submit_comm.Parameters.AddWithValue("@Priority", PriorityList.SelectedValue); Submit_comm.Parameters.AddWithValue("@Requested", RelatedBox.Text); Submit_comm.Parameters.AddWithValue("@Stat", 1); Submit_conn.Open(); Submit_comm.ExecuteNonQuery(); Submit_comm.Dispose(); Submit_comm = null; Submit_conn.Close(); get_Description(); Page.ClientScript.RegisterStartupScript(this.GetType(), "Refresh", "ReloadPage();", true); this function is called by a button on a pop-up form which shows the parameters content that is being changed in a text box which is also used to submit the changes back to the database, but when I press submit, the parameters which are displayed on the form don't change, I can't find any problem wit the code, even though I've compared it to similar code which is working fine. In case you need to, here is one of the text boxes I'm using to display and edit the content: <asp:TextBox ID="JustifBox" TextMode="MultiLine" runat="server" Width="250" Height="50"></asp:TextBox> What exactly is wrong with the code?

  • Basic FreeMat/MATLAB syntax - dimension error

    - by 0x90
    I am using FreeMat, and I have an RGB picture which is a 3D matrix contains the columns and rows of the pictures and the RGB values for each pixel. Since there is not an intrinsic function to convert RGB picture to YIQ, I have implement one. I came up with this code: Assume I have a 3D array, image_rgb: matrix = [0.299 0.587 0.114; 0.596 -0.274 -0.322; 0.211 -0.523 0.312]; row = 1:length(image_rgb(:,1,1)); col = 1:length(image_rgb(1,:,1)); p = image_rgb(row,col,:); %Here I have the problem mage_yiq(row,col,:) = matrix*image_rgb(row,col,:); max_y = max (max(image_yiq(:,:,1))); max_i = max (max(image_yiq(:,:,2))); max_q = max (max(image_yiq(:,:,3))); %Renormalize the image again after the multipication % to [0,1]. image_yiq(:,:,1) = image_yiq(:,:,1)/max_y; image_yiq(:,:,2) = image_yiq(:,:,2)/max_i; image_yiq(:,:,3) = image_yiq(:,:,3)/max_q; I can't understand why the matrix multiplication fails. I want the code to be nice and not just to, multiply the matrix by hand...
