  • Problem running python/matplotlib in background after ending ssh session.

    - by Jamie
    Hi there, I have to VPN and then ssh from home to my work server and want to run a python script in the background, then log out of the ssh session. My script makes several histogram plots using matplotlib, and as long as I keep the connection open everything is fine, but if I log out I keep getting an error message in the log file I created for the script. File "/Home/eud/jmcohen/.local/lib/python2.5/site-packages/matplotlib/pyplot.py", line 2058, in loglog ax = gca() File "/Home/eud/jmcohen/.local/lib/python2.5/site-packages/matplotlib/pyplot.py", line 582, in gca ax = gcf().gca(**kwargs) File "/Home/eud/jmcohen/.local/lib/python2.5/site-packages/matplotlib/pyplot.py", line 276, in gcf return figure() File "/Home/eud/jmcohen/.local/lib/python2.5/site-packages/matplotlib/pyplot.py", line 254, in figure **kwargs) File "/Home/eud/jmcohen/.local/lib/python2.5/site-packages/matplotlib/backends/backend_tkagg.py", line 90, in new_figure_manager window = Tk.Tk() File "/Home/eud/jmcohen/.local/lib/python2.5/lib-tk/Tkinter.py", line 1647, in __init__ self.tk = _tkinter.create(screenName, baseName, className, interactive, wantobjects, useTk, sync, use) _tkinter.TclError: couldn't connect to display "localhost:10.0" I'm assuming that it doesn't know where to create the figures I want since I close my X11 ssh session. If I'm logged in while the script is running I don't see any figures popping up (although that's because I don't have the show() command in my script), and I thought that python uses tkinter to display figures. The way that I'm creating the figures is, loglog() hist(list,x) ylabel('y') xlabel('x') savefig('%s_hist.ps' %source.name) close() The script requires some initial input, so the way I'm running it in the background is python scriptToRun.py << start>& logfile.log& Is there a way around this, or do I just have to stay ssh'd into my machine? Thanks.

  • Problem with multiple forms on one page

    - by Jon
    I have two forms on a web page. The first is not an actual form since this is a .NET based site. So instead I have the standard input fields, along with asp:Button PostBackURL="http:/www...". One of the fields is "email". That works fine. Then I have an XSLT file with another form, and am using Javascript (via this.form.action, .method, etc) to post that form. Besides that it has the same fields as the form above. The problem is that when someone submits the second form, the script at the PostBackURL returns an error because the "email" field appears empty. So it seems as though the form is submitting the "email" field form the top form instead of the current one. I thought maybe the wrong form is being submitted, but if I remove the "email" field from the top form, and then submit the bottom one, it works fine. Any ideas on how to fix this? Thanks.

  • Change the content type of a pop up window.

    - by Oscar Reyes
    This question brought a new one: I have a html page and I need it to change the content type when the user press "save" button so the browser prompt to save the file to disk I've been doing this in the server side to offer "excel" versions of the page ( which is basically a html table ) <c:if test="${page.asExcelAction}"> <% response.setContentType("application/vnd.ms-excel"); %> What I'm trying to do now is to do the same, but in the client side with javacript but I can't manage to do it so. This is what I've got so far: <html> <head> <script> function saveAs(){ var sMarkup = document.getElementById('content').innerHTML; //var oNewDoc = document.open('application/vnd.ms-excel'); var oNewDoc = document.open('text/html'); oNewDoc.write( sMarkup ); oNewDoc.close(); } </script> </head> <body> <div id='content'> <table> <tr> <td>Stack</td> <td>Overflow</td> </tr> </table> </div> <input type="button" value="Save as" onClick="saveAs()"/> </body> </html>

  • Biztalk vs API for databroker layer

    - by jdt199
    My company is about to undergo a large project in which our client wants a large customer portal with a cms, crm implementing. This will require interaction with data from multiple sources across our customers business, these sources include XML office backend systems, sql datbases, webservices etc. Our proposed solution would be to write an API in c# to provide a common interface with all these systems. This would be scalable for future and concurrent projects within the company. Our client expressed an interest in using Biztalk rather than a custom API for this integration, as they feel it is an enterprise solution that any of their suppliers could pick up and use, and it will be better supported. We feel that the configuration work using Biztalk would be rather heavy for all their custom business rules which are required and an interface for the new application to get data to and from Biztalk would still need to be written. Are we right to prefer a custom API solution above Biztalk? Would Biztalk be suitable as a databroker layer to provide an interface for the new Customer portal we are writing. We have not experience with using Biztalk before so any input would be appreciated.

  • Problem with Railscast #197 - Nested Model Form Part 2

    - by sscirrus
    I'm trying to implement Ryan's Railscast #197 in a system with Questions, Answers, and (multiple choice) Options. http://railscasts.com/episodes/197-nested-model-form-part-2. I have successfully implemented the nesting among these forms/partials. The simpler 'check box' way to delete records works properly. The problem occurs when I try to add/delete records. I have copied the code exactly as it appears in his Railscast: #new.html.erb <%= javascript_include_tag :defaults, :cache => true %> <% f.fields_for :in_options do |builder| %> <%= render "option_fields", :f => builder %> <% end %> #_option_fields.html.erb partial <%= f.hidden_field :_destroy %> <%= link_to_function "remove", "remove_fields(this)" %> #application_helper.rb (exact same as #197) def link_to_remove_fields(name, f) f.hidden_field(:_destroy) + link_to_function(name, "remove_fields(this)") end def link_to_add_fields(name, f, association) new_object = f.object.class.reflect_on_association(association).klass.new fields = f.fields_for(association, new_object, :child_index => "new_#{association}") do |builder| render(association.to_s.singularize + "_fields", :f => builder) end link_to_function(name, h("add_fields(this, \"#{association}\", \"#{escape_javascript(fields)}\")")) end #application.js (exact same as #197. I have an Event.addbehavior below this code.) function remove_fields(link) { $(link).previous("input[type=hidden]").value = "1"; $(link).up(".fields").hide(); } function add_fields(link, association, content) { var new_id = new Date().getTime(); var regexp = new RegExp("new_" + association, "g") $(link).up().insert({ before: content.replace(regexp, new_id) }); } 2 problems: When I click on the 'remove' link it doesn't remove - it just shifts the page up or down. When I include link_to_add_fields "Add Answer", f, :answers, I get undefined method `klass' for nil:NilClass. Thanks everyone.

  • Need help coming up with a better HtmlHelper Extension method.

    Hi all, I've inherited the following code and i was wondering if i could pick at your brains to see if there's a nicer way to do duplicate this. Heres the html for most of our partial input views <% if (Html.IsInputReadOnly()) { %> <td> Id </td> <td> <%= Html.TextBox( "Id" , (Model == null ? null : Model.Id) , new { @readonly = "readonly", @disabled="disabled" } )%> <% } elseif (Html.IsInputDisplayable() == false) { %> <td></td> <td></td> <% } else { %> <td>Id</td> <td><%= Html.TextBox("Id")%> <%= Html.ValidationMessage("Id", "*")%> </td> <%} %> Here are my entension methods public static bool IsInputReadOnly(this HtmlHelper helper) { string actionName = ActionName(helper); // The Textbox should be read only on all pages except for the lookup page if (actionName.ToUpper().CompareTo("EDIT") == 0) return true; return false; } public static bool IsInputDisplayable(this HtmlHelper helper) { string actionName = ActionName(helper); // The Textbox should be read only on all pages except for the lookup page if (actionName.ToUpper().CompareTo("CREATE") == 0) return true; return false; } Thanks in advance

  • ListBox Items Not Visible after DataBinding

    - by SidC
    Good Evening All, I am writing a page that allows users to search a parts table, select quantities and a listbox is to be populated with gridview values. Here's a snippet of my aspx page: <asp:ListBox runat="server" ID="lbItems" Width="155px"> <asp:ListItem></asp:ListItem> <asp:ListItem></asp:ListItem> <asp:ListItem></asp:ListItem> <asp:ListItem></asp:ListItem> <asp:ListItem></asp:ListItem> </asp:ListBox> Here's the relevant contents of codebehind: Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load 'Define DataTable Columns as incoming gridview fields Dim dtSelParts As DataTable = New DataTable Dim dr As DataRow = dtSelParts.NewRow() dtSelParts.Columns.Add("PartNumber") dtSelParts.Columns.Add("NSN") dtSelParts.Columns.Add("PartName") dtSelParts.Columns.Add("Qty") 'Select those gridview rows that have txtQty <> 0 For Each row As GridViewRow In MySearch.Rows Dim textboxText As String = _ CType(row.FindControl("txtQty"), TextBox).Text If textboxText <> "0" Then 'Create the row dr = dtSelParts.NewRow() 'Fill the row with data dr("PartNumber") = MySearch.DataKeys(row.RowIndex)("PartNumber") dr("NSN") = MySearch.DataKeys(row.RowIndex)("NSN") dr("PartName") = MySearch.DataKeys(row.RowIndex)("PartName") 'Add the row to the table dtSelParts.Rows.Add(dr) End If Next 'Need to send items to Listbox control lbItems lbItems.DataSource = New DataView(dtSelParts) lbItems.DataValueField = "PartNumber" lbItems.DataValueField = "NSN" lbItems.DataValueField = "PartName" lbItems.DataBind() End Sub The page runs fine in that my search functiobnality is intact, and I can input quantity values into my gridview's textbox. When I click Add to Quote the Listbox receives focus, but no list items are visible. I've created several list items in the aspx page, however I don't know how to populate the contents of my datatable in the listbox. Can someone help a newbie with this, seemingly, easy issue? Thanks, Sid

  • loading custom view using loadNibNamed showing memory leaks

    - by user307550
    I have a number of custom table cells and views that I built using interface builder In interface builder, everything is set up similarly. There is a table cell and a couple other UILabels and a background image Object owner if the nib is NSObject Class for the table cell is the name of the class for my table cell Here is how I create the table cell in my code: SectionedSwitchTableCell *cell = nil; NSArray *nibs = [[NSBundle mainBundle] loadNibNamed:kSectionedSwitchTableCellIdentifier owner:owner options:nil]; for(id currentObject in nibs) { if([currentObject isKindOfClass:[SectionedSwitchTableCell class]]) { cell = (SectionedSwitchTableCell *)currentObject; break; } } return cell; For my custom table headers I have this NSArray *nibs = [[NSBundle mainBundle] loadNibNamed:@"CustomTableHeader" owner:self options:nil]; for(id currentObject in nibs) { if([currentObject isKindOfClass:[CustomTableHeader class]]) { return header } } In my .h and .m files for the custom view, I have IBOutlet, @property set up for everything except for the background image UIImageView. Everything that has the IBOutlet and @property are also @synthesized and released in the .m file. Leaks is showing that I have memory leaks with CALayer when I create these custom view objects. Am I doing something wrong here when I create these custom view objects? I'm kind of tearing my hair out trying to figure out where these leaks are coming from. As a side note, I have a UIImageView background image defined in these custom views but I didn't define properties and IBOutlets in my .h and .m files. Defining them doesn't make a difference when I run it through Leaks but just wanted to confirm if I'm doing the right thing. Any input would be super helpful. Thanks :)

  • oracle hibernate + maven dependenciesm dbcp.basicdatasource exception

    - by Joe
    I'm trying to create a web application using maven, tomcat and hibernate. Now I'm getting a cannot find class for org.appache.commons.dbcp.basicdatasource for bean with name datasource... exception. Without the hibernate aspects it works fine, but if I add <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> <property name="dataSource" ref="dataSource"/> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect">org.hibernate.dialect.Oracle10gDialect</prop> <prop key="hibernate.hbm2ddl.auto">create</prop> <prop key="hibernate.show_sql">true</prop> </props> </property> <property name="mappingResources"> <list> </list> </property> </bean> to my applicationContext then I get the error. What I did was: -add org.hibernate to my pom -put ojdbc16.jar in my tomcat bin folder -add the above snippet to my applicationContext.xml I use a bat file to compile my project (using maven), copy it to my tomcat webapp folder and to start the server. Any input on what I'm doing wrong is welcome.

  • what are the possibilities of displaying items in a listbox.

    - by Selase
    Ive been trying to figure out for a long time now how to create an interface that can allows users to input several rows of data and passed those entries into an sql server database all at one shot. i could not get any better ideas so i came up with this.(see picture below.) so what i envisioned is that the user enters values in the textboxes and hits "add to list" button. the values are then populated in the list box below with the heading "exhibits lists" and when add exhibit button is pressed, all values from the list box are passed into the database. Well am left wondering again if it would be possible to tie this values from the texboxes to the list box and if id be able to pass them into the database. if it were possible then id please love to know how to go about it otherwise id be glad if you can recommend a better way for me to handle the situation otherwise id have to resolve to data entry one at a time.:(... Counting on you sublime advise. thanks. I believe there is some useful information from this website that can help solve my problem but i just cant make head and tail out of the article...it seems like am almost there and it skids off...can everyone please read and help me adapt it to my situation..thanks..post below http://www.codeproject.com/KB/aspnet/ExtendedGridView.aspx

  • UI Design, incase of numerous situations

    - by The King
    Hi... I'm creating a web form, where in there are around 12-15 Input Fields... You can have a look at the screen and The request is such that depending on the data the user selects in the Gridview and the DropDown list, the appropriate Textboxes and CheckBoxes needs to be displayed. Some times the conditions are very direct, like when the DDL value is "ABC", get only paid amount from the user. Sometime they are so complex like... IF DDL is "DEF" and Selected GPMS value is between 1000-2000, calculate the values of allowed, paid etc (using some formula) and the focus should be directed to Page No Field, leaving the other fields open incase user wants to edit... There are around 10-15 conditions like this. As this was done through agile, conditions were being added as and when, and wherever it feels appropriate (DDL on change Event, GridView on selecting change event etc... etc..) After completion, now I see the code has become a big chuck, is growing unmanageably... Now, I'm planning to clear this... From you experience, what you think is the best way to handle this. There is a possibility to add more conditions like this in future... Please let me know, incase you need more information. I'm currently developing this app in C# .Net WindowsForms Edit: Currently there are only three items (The Datagrid, the DDL, the OverrideAmt CheckBox) that change the way other fields behave... Almost all of the conditions will fall between the two situations I mentioned... Mostly they belong to "Enabling/Disabling".. "Setting of Values"... and "Changing Focus" or any combination of these.

  • Redirect parent of a page from a cfwindow

    - by Ryan French
    Hi All, I have a page with cfwindow that require the user to be logged in to view the content on the page. The problem at the moment is if the user logs into the site, then does nothing and the session times out, I have no way that I can think of to redirect the parent of the window to the login screen when the user opens it. So far I have tried using cflocation but that has no way of specifying the container that should be redirected (i.e. the page in the window is being redirected but not the windows parent). I have also thought about using a hidden input with a value based on the session which is then check with Body onLoad event but currently this doesnt work with how the pages have been setup. The last option I have is to check the session variable on loading the window and then closing it if the user is not logged in, which will cause the parent to refresh and redirect to login anyway. However I cant find a way to close a cfwindow without using javascript. Thanks for any help you can give.

  • Write to a textfile using Javascript

    Under Firefox, I want to do something like this : I have a .htm file, that has a button on it. This button, when I click it, the action will write a text inside a local .txt file.

  • Memory leak when changing Text field of a Scintilla object.

    - by PlaZmaZ
    I have a relatively large program that I'm optimizing for ASCII input files around 10-80mB in size. The program reads every line of the file into a stringbuilder and then sets the Text field of the ScintillNET object to the stringbuilder. The stringbuilder is then set to null. private void ReloadFile(string sFile) { txt_log.ResetText(); try { StringBuilder sLine = new StringBuilder(""); using (StreamReader sr = new StreamReader(sFile)) { while (true) { string temp = sr.ReadLine(); if (temp == null) break; sLine.AppendLine(temp); } sr.Close(); } txt_log.Text = sLine.ToString(); sLine = null; } catch (Exception ex) { MessageBox.Show(this, "An error occurred opening this file.\n\n" + ex.Message, "File Open Error", MessageBoxButtons.OK, MessageBoxIcon.Error); } GC.Collect(); } The program has an option to reload or open a file. This is irrelevant, as any call to txt_log.Text seems to not get rid of the previous memory used for the .Text field. Commenting out the txt_log.Text line gives proper memory behavior. The GC.Collect() line seems pointless, and I have tried both with and without it. Is there something I'm missing here? I HIGHLY doubt it's a problem with the ScintillaNET component itself--rather something in this code.

  • Passing Binary Data to a Stored Procedure in SQL Server 2008

    - by Joe Majewski
    I'm trying to figure out a way to store files in a database. I know it's recommended to store files on the file system rather than the database, but the job I'm working on would highly prefer using the database to store these images (files). There are also some constraints. I'm not an admin user, and I have to make stored procedures to execute all the commands. This hasn't been of much difficulty so far, but I cannot for the life of me establish a way to store a file (image) in the database. When I try to use the BULK command, I get an error saying "You do not have permission to use the bulk load statement." The bulk utility seemed like the easy way to upload files to the database, but without permissions I have to figure a work-a-round. I decided to use an HTML form with a file upload input type and handle it with PHP. The PHP calls the stored procedure and passes in the contents of the file. The problem is that now it's saying that the max length of a parameter can only be 128 characters. Now I'm completely stuck. I don't have permissions to use the bulk command and it appears that the max length of a parameter that I can pass to the SP is 128 characters. I expected to run into problems because binary characters and ascii characters don't mix well together, but I'm at a dead end... Thanks

  • c multithreading

    - by coubeatczech
    hi, there's a weird behaviour in my threads: void * foo(void * nic){ printf("foo"); } void * threadF(void * ukazatel){ printf("1\n"); pthread_t threadT; pthread_attr_t attr; pthread_attr_init (&attr); pthread_attr_setdetachstate(&attr, PTHREAD_CREATE_JOINABLE); pthread_create(&threadT,NULL,&foo,(void*)NULL); printf("2\n"); while (!feof(stdin)){ int id, in, out; fscanf(stdin,"%d:%d:%d",&id,&in,&out); } } int main(){ pthread_attr_t attr; pthread_attr_init (&attr); pthread_attr_setdetachstate(&attr, PTHREAD_CREATE_JOINABLE); pthread_t threadT; pthread_create(&vlaknoVstupu,&attr,&threadF,(void*)&data); pthread_join(threadT,NULL); pthread_attr_destroy (&attr); } // I skipped irelevant parts of code... the thing is, that sometimes, the output is 12foo, but usually just 12. Then the function waits for input. I would expect it to be always 12foo. Do anybody know why are my expectations wrong?

  • hadoop implementing a generic list writable

    - by Guruprasad Venkatesh
    I am working on building a map reduce pipeline of jobs(with one MR job's output feeding to another as input). The values being passed around are fairly complex, in that there are lists of different types and hash maps with values as lists. Hadoop api does not seem to have a ListWritable. Am trying to write a generic one, but it seems i can't instantiate a generic type in my readFields implementation, unless i pass in the class type itself: public class ListWritable<T extends Writable> implements Writable { private List<T> list; private Class<T> clazz; public ListWritable(Class<T> clazz) { this.clazz = clazz; list = new ArrayList<T>(); } @Override public void write(DataOutput out) throws IOException { out.writeInt(list.size()); for (T element : list) { element.write(out); } } @Override public void readFields(DataInput in) throws IOException{ int count = in.readInt(); this.list = new ArrayList<T>(); for (int i = 0; i < count; i++) { try { T obj = clazz.newInstance(); obj.readFields(in); list.add(obj); } catch (InstantiationException e) { e.printStackTrace(); } catch (IllegalAccessException e) { e.printStackTrace(); } } } } But hadoop requires all writables to have a no argument constructor to read the values back. Has anybody tried to do the same and solved this problem? TIA.

  • How to debug PHP?

    - by NutMotion
    Anyone's been trying himself at object oriented programming ? Most probably every developer I guess:D I for one have never studied OO design patterns thoroughly, and trying to put it all together now does prove at times thrilling, and many times frustrating also. Even more so when trying to do it in : PHP! All-in-all, my boss asked me to add some Database persistence functions to her server, but most of all, she asked me to translate her already working procedural code into a working Object Oriented code. Here I am, still standing on my PHP OO project. I'm (already) fed up with this "file logging only" PHP capability. I believe there must be some (free or not too much expansive) PHP debugging utility ? I've heard about Zend Studio and PHPEd so far, which didn't quite do the trick for whatever reasons. WIRCW("Which I don't Remember Correctly Why" lol) What say yé? on debugging PHP ? Is there a tool that provides a good debug mode? what's more, don't forget I'm not speaking about the classical web Request/response model. Talking about a debugging facility which can enable you to trigger a web service (aka client request) and go into debug mode on the SOAP web service side. Thks for any input.

  • Help with Struts Action mapping

    - by nicotine
    I am having a problem with my struts application it is a class enrollment app and when the user clicks on a "show enrolled courses" button it is supposed to show the courses they are enrolled in but it shows nothing at the moment. Struts/Apache does not return any errors, it Just shows a blank page and I cannot figure out why. My action mapping in my struts-config: <action path="/showEnrolled" type="actions.ShowEnrolledAction" name="UserFormEnrolled" scope="request" validate="true" input="/students/StudentMenu.jsp"> <forward name="success" path="/students/enrolled.jsp"/> </action> My link to the jsp enrolled.jsp page: <li><html:form action="/showEnrolled"> <html:hidden property="id" value= "<%=request.getRemoteUser()%>"/> <html:submit value = "View Enrolled Classes"/> </html:form> </li> When I click the link I get nothing but my menu on the page. The text headings for the page are not even displayed.

  • Retrieve a TextBox element dinamically created and Focus it

    - by user335444
    Hi, I have a collection (VariableValueCollection) of custom type VariableValueViewModel objects binded with a ListView. WPF Follow: <ListView ItemsSource="{Binding VariableValueCollection}" Name="itemList"> <ListView.Resources> <DataTemplate DataType="{x:Type vm:VariableValueViewModel}"> <Grid> <Grid.ColumnDefinitions> <ColumnDefinition Width="180"></ColumnDefinition> </Grid.ColumnDefinitions> <TextBox TabIndex="{Binding Path=Index, UpdateSourceTrigger=PropertyChanged, Mode=TwoWay}" Grid.Column="0" Name="tbValue" Focusable="True" LostFocus="tbValue_LostFocus" GotFocus="tbValue_GotFocus" KeyDown="tbValue_KeyDown"> <TextBox.Text> <Binding Path="Value" UpdateSourceTrigger="PropertyChanged" Mode="TwoWay"> <Binding.ValidationRules> <ExceptionValidationRule></ExceptionValidationRule> </Binding.ValidationRules> </Binding> </TextBox.Text> </TextBox> </Grid> </DataTemplate> </ListView.Resources> </ListView> My Goal is to add a new row when I press "enter" on last row, and Focus the new row. To do that, I check that row is the last row and add a new row in that case. But I don't know how to focus the new TextBox... Here the KeyPressed method: private void tbValue_KeyDown(object sender, KeyEventArgs e) { if (e.Key == System.Windows.Input.Key.Enter) { DependencyObject obj = itemList.ContainerFromElement((sender as TextBox)); int index = itemList.ItemContainerGenerator.IndexFromContainer(obj); if( index == (VariableValueCollection.Count - 1) ) { // Create a VariableValueViewModel object and add to collection. In binding, that create a new list item with a new TextBox ViewModel.AddNewRow(); // How to set cursor and focus last row created? } } } Thank's in advance...
