  • How to use sprintf instead of hardcoded values

    - by astha goyal
    I am developing a firewall for Linux as my project. I am able to capture packets and to block them. I am using IPTABLES. How can I use variables with sprintf instead of hardcoded values? sprintf(comm, "iptables -A INPUT -s $str -j DROP") // inplace of: sprintf(comm, "iptables -A INPUT -s 192.168.0.43 -j DROP")

  • Multiline values in dropdown (ComboBox)

    - by Vladimir Kuzin
    Is there are any libraries to make ComboBox to select multiline options when expanded. I am looking something similar to Combobox in ExtJS except values have to appear when user clicks down arrow, like in normal dropdown. Does someone know if its possible to do something like that with ExtJS? Because their own community and support sure doesn’t (http://www.extjs.com/forum/showthread.php?t=94079)

  • XQuery method question, trying to sum values read from xml

    - by Buck
    I'm pretty new to XQuery and I'm trying to write an example function that I can't get to work. I want to read an xml file, parse out the "time" values, sum them as they're read and return the sum. This is trivial and I'm looking to build more functionality into it but I'd like to get this working first. Also, I know there's a "sum" directive in XQuery that would do just this but I want to add more to it so the built-in sum is insufficient for my needs. Here's my funtion: bool example(Zorba* aZorba) { XQuery_t lQuery = aZorba-compileQuery( "for $i in fn:doc('/tmp/products.xml')//time" "let $sum := xs:integer($i)" " return $sum" ); DynamicContext* lCtx = lQuery-getDynamicContext(); lCtx-setContextItemAsDocument("temp_measurements.xml", lDocStream); try { std::cout << lQuery << std::endl; } catch (DynamicException& e) { std::cerr << e.getDescription() << std::endl; return false; } catch (StaticException& f){ std::cerr << f.getDescription() << f.getErrorCodeAsString(f.getErrorCode()) << std::endl; return false; } } It's called with an appropriate main(). If I comment out the line that starts "let $sum..." then this works in that it returns the time values as a series of integers like this: 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 3 3 3 3 3 3 3 3 3.... Input file looks like this: <?xml version="1.0" encoding="UTF-8"? <temps <temp <time0</time <lat0</lat <long0</long <value0</value </temp <temp <time1</time <lat0</lat <long1</long <value0</value </temp ...

  • MPXJ - get ResourceAssignment baseline values

    - by patmortech
    I'm trying to display the Baseline Start, Finish, Cost, and Work values for a ResourceAssignment, but cannot seem to find any methods on the ResourceAssignment object that would provide this information. Anybody know if this is possible? I know the information is stored because I can see it in MS Project, and I can see it in the XML version of the project file. Just can't see in the API where to get access to it.

  • Checkbox has the wrong values

    - by Praesagus
    I have a page with several checkboxes on it, along with a dropdownlist of users. The checkboxes correlate to the user's permissions so each user is different. When a different user is chosen, the check boxes should change to match that user's permissions. The codebehind is correct, I stepped through it and the checkbox.checked value is being assigned to the box with the correct value to match the user. chk.Checked = viewable; No matter what I assign to the checked property the value stays the same as the very first submittal. I tried chk.EnableViewState = false; but that did not help. I am sure it is dot net trying to be helpful (grrr). Thank you for your help. There is no databinding per se. I will be saving the values from the textboxes via xmlhttp when the user clicks on them. I never want the check boxes to fill with values other than what I give them. Here is the essence of the code. foreach (DataRow dRow in dTable.Rows) { viewable = Convert.ToBoolean(dRow["Viewable"]); table.Rows.Add(CreatePageRow(Convert.ToString(dRow["SitePageViewName"]), Convert.ToString(dRow["SitePageName"]), folderDepth, maxFolderDepth, viewable)); } FileTree.Controls.Add(table); private TableRow CreatePageRow(String ViewName, String FileName, Int32 folderDepth, Int32 maxFolderDepth, Boolean viewable) { TableRow tr = new TableRow(); tr.Cells.Add(CreateCheckboxCell(viewable, folderDepth+3)); tr.Cells.Add(CreateImageCell("/images/icon/sm/report_graph.gif", "Page: " + ViewName)); tr.Cells.Add(CreateTitleCell(ViewName, maxFolderDepth - (folderDepth+1), FileName)); return tr; } private TableCell CreateCheckboxCell(Boolean viewable, Int32 colSpan) { TableCell td = new TableCell(); if (colSpan > 1) td.ColumnSpan = colSpan; CheckBox chk = new CheckBox(); chk.Checked = viewable; chk.EnableViewState = false; td.Controls.Add(chk); td.CssClass = "right"; return td; }

  • delete all but minimal values, based on two columns in SQL Server table

    - by sqlill
    how to write a statement to accomplish the folowing? lets say a table has 2 columns (both are nvarchar) with the following data col1 10000_10000_10001_10002_10002_10002 col2 10____20____10____30____40_____50 I'd like to keep only the following data: col1 10000_10001_10002 col2 10____10____30 thus removing the duplicates based on the second column values (neither of the columns are primary keys), keeping only those records with the minimal value in the second column. how to accomplish this?

  • Search for multiple values in an xml column

    - by Yuriy Gettya
    Environment: SQL Server 2012. Primary and secondary (value) index is built on xml column. Say I have a table Message with xml column WordIndex. I also have a table Word which has WordId and WordText. Xml for Message.WordIndex has the following schema: <xs:schema attributeFormDefault="unqualified" elementFormDefault="qualified" xmlns:xs="http://www.w3.org/2001/XMLSchema" targetNamespace="http://www.example.com"> <xs:element name="wi"> <xs:complexType> <xs:sequence> <xs:element maxOccurs="unbounded" name="w"> <xs:complexType> <xs:sequence> <xs:element maxOccurs="unbounded" name="p" type="xs:unsignedByte" /> </xs:sequence> <xs:attribute name="wid" type="xs:unsignedByte" use="required" /> </xs:complexType> </xs:element> </xs:sequence> </xs:complexType> </xs:element> </xs:schema> and some data to go with it: <wi xmlns="http://www.example.com"> <w wid="1"> <p>28</p> <p>72</p> <p>125</p> </w> <w wid="4"> <p>89</p> </w> <w wid="5"> <p>11</p> </w> </wi> I need to search for multiple values in my xml column WordIndex either using OR or AND. What I'm doing is fairly rudimentary, since I'm a n00b in XQuery (taken from debug output, hence real values): with xmlnamespaces(default 'http://www.example.com') select m.Subject, m.MessageId, m.WordIndex.query(' let $dummy := 0 return <word_list> { for $w in /wi/w where $w/@wid=64 return <word wid="64" pos="{data($w/p)}"/> } { for $w in /wi/w where $w/@wid=70 return <word wid="70" pos="{data($w/p)}"/> } { for $w in /wi/w where $w/@wid=63 return <word wid="63" pos="{data($w/p)}"/> } </word_list> ') as WordPosition from Message as m -- more joins go here ... where -- more conditions go here ... and m.WordIndex.exist('/wi/w[@wid=64]') = 1 and m.WordIndex.exist('/wi/w[@wid=70]') = 1 and m.WordIndex.exist('/wi/w[@wid=63]') = 1 How can this be optimized?

  • accessing array values without square brackets in php

    - by amb
    In php how can I access an array's values without using square brackets around the key? My particular problem is that I want to access the elements of an array returned by a function. Say function(args) returns an array. Why is $var = function(args)[0]; yelling at me about the square brackets? Can I do something like $var = function(args).value(0); or am I missing something very basic?

  • Choosing the default value of an Enum type without having to change values

    - by frou
    In C#, is it possible to decorate an Enum type with an attribute or do something else to specify what the default value should be, without having the change the values? The numbers required might be set in stone for whatever reason, and it'd be handy to still have control over the default. enum Orientation { None = -1, North = 0, East = 1, South = 2, West = 3 } Orientation o; // Is 'North' by default.

Say by joining to another table perhaps?

  • Dynamically adding values to a form with JQuery/Javascript

    - by bigstylee
    I am creating a private message system to allow users to communicate between one another within the context of the website (ie, not emails). I have created this function to handle all my form submissions. I would like to achieve a solution without modifying this function (ideally). $("form.reload").submit(function(){ alert($(this).serialize()); /* Debugging */ $.post($(this).attr("action"), $(this).serialize() ,function(data){ if(data){ $("#error").html(data); }else{ location.reload(); }; }); return false; }); Within my form I am using JQuery Autocomplete to find usernames. This function works perfectly. My first solution was to add buttons within the form with the necessary values. select: function(event, ui) { $("#message_to").append("<input type=\"button\" class=\"recipient\" name=\"recipients[]\" value=\"" + ui.item.label + "\" onclick=\"$(this).remove()\" />"); } <form method="post" action="/messages-create"> <div id="message_to"></div> </div> For some reason the values of recipients are not getting posted. My second solution was to add to a post array that already existed in the form select: function(event, ui) { $(input[name=recipeients[]).val = ui.item.label; /* Need to add to array, not replace! */ $("#message_to").append("<input type=\"button\" class=\"recipient\" name=\"recipient\" value=\"" + ui.item.label + "\" onclick=\"$(this).remove(); /* Remove from recipients */\" />"); } <form method="post" action="/messages-create" class="reload"> <input type="hidden" name="recipients[]" value="" /> <div id="message_to"></div> </div> This works ok, but I have been unable to work out how to append to the recipients[] array only replace with the new label. Moving on from this, I also need to know how to then remove this value from the array. Thanks in advance!
