    I have created two xml files from those xml file i would like to compare one xml file with another xml file and update the xml file. I have created an xml file as follows: main.xml <?xml version="1.0" encoding="utf-8"?> <ScrollView xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:background="#00BFFF"> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical"> <LinearLayout android:id="@+id/linearLayout1" android:layout_width="fill_parent" android:layout_height="wrap_content" android:gravity="center" android:visibility="visible"> </LinearLayout> <LinearLayout android:id="@+id/linearLayout2" android:layout_width="fill_parent" android:layout_height="wrap_content" android:gravity="center" android:visibility="visible"> </LinearLayout> </LinearLayout> </ScrollView> properties.xml <?xml version='1.0' encoding='utf-8' standalone='yes' ?> <map> <int name="linearLayout1" value="8" /> <int name="linearLayout2" value="0" /> </map> from the above two xml files i would like to compare with LinearLayout android:id ="@id/LinearLayout1" from main.xml with int name ="linearLayout1" from properties.xml. from the above properties.xml file where name ="linearLayout1" and value ="8" then i would like to update the main.xml file where as LinearLayout android:id="@id/linearLayout1" propertie value as android:visibility="gone" From the above xml file how can i update main.xml file by comparing properties.xml? please any body help me.....

  • System.InvalidOperationException in Output Window

  • jitter if multiple outliers in ggplot2 boxplot

    - by Andreas
    I am trying to find a suitable display to illustrate various properties within and across school classes. For each class there is only 15-30 data points (pupils). Right now i am leaning towards a whisker-less boxplot, showing only 1.,2. and 3. quartile + datapoints more then e.g. 1 population SD +/- the sample median. This I can do. However - I need to show this graph to some teachers, in order to gauge what they like most. I'd like to compare my graph with a normal boxplot. But the normal boxplot looks the same if there is only one outlier, or e.g. 5 outliers at the same value. In this case this would be a deal-breaker. e.g. test <-structure(list(value = c(3, 5, 3, 3, 6, 4, 5, 4, 6, 4, 6, 4, 4, 6, 5, 3, 3, 4, 4, 4, 3, 4, 4, 4, 3, 4, 5, 6, 6, 4, 3, 5, 4, 6, 5, 6, 4, 5, 5, 3, 4, 4, 6, 4, 4, 5, 5, 3, 4, 5, 8, 8, 8, 8, 9, 6, 6, 7, 6, 9), places = structure(c(1L, 2L, 1L, 1L, 1L, 2L, 1L, 2L, 1L, 2L, 1L, 2L, 2L, 2L, 2L, 2L, 1L, 1L, 2L, 2L, 2L, 1L, 2L, 1L, 1L, 1L, 1L, 2L, 1L, 2L, 1L, 2L, 2L, 2L, 1L, 2L, 1L, 2L, 2L, 1L, 1L, 2L, 2L, 1L, 1L, 1L, 1L, 2L, 1L, 1L, 2L, 2L, 2L, 1L, 1L, 2L, 2L, 1L, 2L, 1L), .Label = c("a", "b"), class = "factor")), .Names = c("value", "places"), row.names = c(NA, -60L), class = "data.frame") ggplot(test, aes(x=places,y=value))+geom_boxplot() Here there are two outliers at ("a",9) - but only one "dot" shown. So my question: How to jitter the outliers. And - what kind of display would you suggest for this kind of data?

  • Problem with multiple select removing more than 1 option

    - by SoLoGHoST
    Ok, there seems to be a problem with the JS Code for Opera browsers, as it only removes the last option tag that is selected within a multiple select tag, can someone please help me. Here is the HTML for this: <select id="actions_list" name="layouts" multiple style="height: 128px; width: 300px;"> <option value="forum">forum</option> <option value="collapse">collapse</option> <option value="[topic]">[topic]</option> <option value="[board]">[board]</option> </select> Ofcourse it's within a form tag, but there's a ton more code involved with this form, but here is the relevant info for this. Here is the JS that should handle this, but only removes the last selected option in Opera, not sure about other browsers, but it really needs to remove all selected options, not just the last selected option... argg var action_list = document.getElementById("actions_list"); var i = action_list.options.length; while(i--) { if (action_list.options[i].selected) { action_list.remove(i); } } What is wrong with this? I can't figure it out one bit :( Thanks :)

  • Is it possible in any Java IDE to collapse the type definitions in the source code?

    - by asmaier
    Lately I often have to read Java code like this: LinkedHashMap<String, Integer> totals = new LinkedHashMap<String, Integer>(listOfRows.get(0)) for (LinkedHashMap<String, Integer> row : (ArrayList<LinkedHashMap<String,Integer>>) table.getValue()) { for(Entry<String, Integer> elem : row.entrySet()) { String colName=elem.getKey(); int Value=elem.getValue(); int oldValue=totals.get(colName); int sum = Value + oldValue; totals.put(colName, sum); } } Due to the long and nested type definitions the simple algorithm becomes quite obscured. So I wished I could remove or collapse the type definitions with my IDE to see the Java code without types like: totals = new (listOfRows.get(0)) for (row : table.getValue()) { for(elem : row.entrySet()) { colName=elem.getKey(); Value=elem.getValue(); oldValue=totals.get(colName); sum = Value + oldValue; totals.put(colName, sum); } } The best way of course would be to collapse the type definitions, but when moving the mouse over a variable show the type as a tooltip. Is there a Java IDE or a plugin for an IDE that can do this?

  • In .NET, Why Can I Access Private Members of a Class Instance within the Class?

    - by AMissico
    While cleaning some code today written by someone else, I changed the access modifier from Public to Private on a class variable/member/field. I expected a long list of compiler errors that I use to "refactor/rework/review" the code that used this variable. Imagine my surprise when I didn't get any errors. After reviewing, it turns out that another instance of the Class can access the private members of another instance declared within the Class. Totally unexcepted. Is this normal? I been coding in .NET since the beginning and never ran into this issue, nor read about it. I may have stumbled onto it before, but only "vaguely noticed" and move on. Can anyone explain this behavoir to me? I would like to know the "why" I can do this. Please explain, don't just tell me the rule. Am I doing something wrong? I found this behavior in both C# and VB.NET. The code seems to take advantage of the ability to access private variables. Sincerely, Totally Confused Class Jack Private _int As Integer End Class Class Foo Public Property Value() As Integer Get Return _int End Get Set(ByVal value As Integer) _int = value * 2 End Set End Property Private _int As Integer Private _foo As Foo Private _jack As Jack Private _fred As Fred Public Sub SetPrivate() _foo = New Foo _foo.Value = 4 'what you would expect to do because _int is private _foo._int = 3 'TOTALLY UNEXPECTED _jack = New Jack '_jack._int = 3 'expected compile error _fred = New Fred '_fred._int = 3 'expected compile error End Sub Private Class Fred Private _int As Integer End Class End Class

  • Perl: POST request how?

    - by Peterim
    Unfortunately, I'm not familiar with Perl, so asking here. Actually I'm using FCGI with Perl. I need to 1. accept a POST request - 2. send it via POST to another url - 3. get results - 4. return results to the first POST request (4 steps). To accept a POST request (step 1) I use the following peace of code (found it somewhere in the Internet): $ENV{'REQUEST_METHOD'} =~ tr/a-z/A-Z/; if ($ENV{'REQUEST_METHOD'} eq "POST") { read(STDIN, $buffer, $ENV{'CONTENT_LENGTH'}); } else { print ("some error"); } @pairs = split(/&/, $buffer); foreach $pair (@pairs) { ($name, $value) = split(/=/, $pair); $value =~ tr/+/ /; $value =~ s/%(..)/pack("C", hex($1))/eg; $FORM{$name} = $value; } The content of $name (it's a string) is the result of the first step. Now I need to send $name via POST request to some_url (step 2) which returns me another result (step 3), which I have to return as a result to the very first POST request (step 4). Any help with this would be greatly appreciated. Thank you.

  • If I'm using a 1d array to represent a square board, how can I take my index and check the sqaures a

    - by FrankTheTank
    If I have a 4x4 gameboard which I'm representing in my program as a 1d integer array of size 16. How can I get the indexs of the squares above, below, to the left and to the right any given index? So, for example: A = { 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 } Which represents this board 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 Lets say I am currently on index #8 in the board (value = 7). How can I get the index for 4 (value = 3) , 5 (value = 6), 10 (value = 11) and realize that there is no right square because it is on the right hand edge of the board. I know I need to use some modulus math but I'm failing to come up with the right way to get the indexes for adjacent squares. I'm thinking something like... if ((i % 4) + 1 < 3) right = i + 1; if ((i % 4) - 1 > 0) left = i - 1; if ((i % 4) + 4 < 15) bottom = i + 4; if ((i % 4) - 4 > 0 ) top = i - 4; Does this seem like it is the right approach?

  • Is there a way to do 'correct' arithmetical rounding in .NET? / C#

    - by Markus
    I'm trying to round a number to it's first decimal place and, considering the different MidpointRounding options, that seems to work well. A problem arises though when that number has sunsequent decimal places that would arithmetically affect the rounding. An example: With 0.1, 0.11..0.19 and 0.141..0.44 it works: Math.Round(0.1, 1) == 0.1 Math.Round(0.11, 1) == 0.1 Math.Round(0.14, 1) == 0.1 Math.Round(0.15, 1) == 0.2 Math.Round(0.141, 1) == 0.1 But with 0.141..0.149 it always returns 0.1, although 0.146..0.149 should round to 0.2: Math.Round(0.145, 1, MidpointRounding.AwayFromZero) == 0.1 Math.Round(0.146, 1, MidpointRounding.AwayFromZero) == 0.1 Math.Round(0.146, 1, MidpointRounding.ToEven) == 0.1 Math.Round(0.146M, 1, MidpointRounding.ToEven) == 0.1M Math.Round(0.146M, 1, MidpointRounding.AwayFromZero) == 0.1M I tried to come up with a function that addresses this problem, and it works well for this case, but of course it glamorously fails if you try to round i.e. 0.144449 to it's first decimal digit (which should be 0.2, but results 0.1.) (That doesn't work with Math.Round() either.) private double round(double value, int digit) { // basically the old "add 0.5, then truncate to integer" trick double fix = 0.5D/( Math.Pow(10D, digit+1) )*( value = 0 ? 1D : -1D ); double fixedValue = value + fix; // 'truncate to integer' - shift left, round, shift right return Math.Round(fixedValue * Math.Pow(10D, digit)) / Math.Pow(10D, digit); } I assume a solution would be to enumerate all digits, find the first value larger than 4 and then round up, or else round down. Problem 1: That seems idiotic, Problem 2: I have no idea how to enumerate the digits without a gazillion of multiplications and subtractios. Long story short: What is the best way to do that?

  • Cascading input control is empty while accessing a Jasper Report

    - by Yogesh R
    I call a jasper report through an independent URL through which I pass one of the input controls needed to run the report. E.g. http:// localhost:8080/jasperserver/flow.html?_flowId=viewReportFlow&standAlone=true&reportUnit=xyz&ParentFolderUri=abcd&j_username=xyz&j_password=xyz&parameter1=value1& . . . As you can see in the URL, I pass the JasperServer username and password, reportUnit name and location and other mandatory parameters, along with the report input parameter, i.e., "parameter1" which can have a value like "value1". I used a mandatory, read-only and visible input control for this input value. Its value would come from the URL, showed in the box but was read-only and hence could not be changed. The report was working absolutely fine upto this point. But the tragedy began when my client rejected this idea. He wanted a completely invisible input control to my report and the input value would be passed through the URL, just like illustrated above. And then my client asked me to refer to this and made me work on cascading input controls. Recently I added a cascading input control to this report. The input control type is a single select query, which utilizes two parameters that I pass to the report through the URL. Now when the Jasper server responds to the URL with the input parameters, all the other static parameters work properly, except for the cascaded one. When I click the select box of the cascaded input, I can see the desired options for a second, and then, it just goes empty while I'm viewing the select list. But when I make the "Parameter1" input control visible, the cascading input control works! And then I turn in invisible, the cascading input control turns into a beast that does things by itself and not listen to his master. I am not able to understand why this is happening. Could anybody please provide me a solution to this?

  • jQuery + Jeditable - detect when select is changed

    - by Bryan Roth
    I'm using Jeditable for in-place editing. One the controls I am working with has the select type. When a user clicks on the field, the following select control is generated: <div id="status" class="editable_select"> <form> <select name="value"> <option value="Active">Active</option> <option value="Inactive">Inactive</option> </select> <button type="submit">Save</button> <button type="cancel">Cancel</button> </form> </div> What I am trying to figure out is how to use jQuery to detect when that select control is changed, especially since it doesn't have an ID attribute. This is what I have so far, but the event is not getting triggered: $(document).ready(function () { $('#status select').change(function () { alert("Change Event Triggered On:" + $(this).attr("value")); }); });

  • How do I associate Parameters to Command objects in ADO with VBScript?

    - by Krashman5k
    I have been working an ADO VBScript that needs to accept parameters and incorporate those parameters in the Query string that gets passed the the database. I keep getting errors when the Record Set Object attempts to open. If I pass a query without parameters, the recordset opens and I can work with the data. When I run the script through a debugger, the command object does not show a value for the parameter object. It seems to me that I am missing something that associates the Command object and Parameter object, but I do not know what. Here is a bit of the VBScript Code: ... 'Open Text file to collect SQL query string' Set fso = CreateObject("Scripting.FileSystemObject") fileName = "C:\SQLFUN\Limits_ADO.sql" Set tso = fso.OpenTextFile(fileName, FORREADING) SQL = tso.ReadAll 'Create ADO instance' connString = "DRIVER={SQL Server};SERVER=myserver;UID=MyName;PWD=notapassword; Database=favoriteDB" Set connection = CreateObject("ADODB.Connection") Set cmd = CreateObject("ADODB.Command") connection.Open connString cmd.ActiveConnection = connection cmd.CommandText = SQL cmd.CommandType = adCmdText Set paramTotals = cmd.CreateParameter With paramTotals .value = "tot%" .Name = "Param1" End With 'The error occurs on the next line' Set recordset = cmd.Execute If recordset.EOF then WScript.Echo "No Data Returned" Else Do Until recordset.EOF WScript.Echo recordset.Fields.Item(0) ' & vbTab & recordset.Fields.Item(1) recordset.MoveNext Loop End If The SQL string that I use is fairly standard except I want to pass a parameter to it. It is something like this: SELECT column1 FROM table1 WHERE column1 IS LIKE ? I understand that ADO should replace the "?" with the parameter value I assign in the script. The problem I am seeing is that the Parameter object shows the correct value, but the command object's parameter field is null according to my debugger.

  • Help me understand Inorder Traversal without using recursion

    - by vito
    I am able to understand preorder traversal without using recursion, but I'm having a hard time with inorder traversal. I just don't seem to get it, perhaps, because I haven't understood the inner working of recursion. This is what I've tried so far: def traverseInorder(node): lifo = Lifo() lifo.push(node) while True: if node is None: break if node.left is not None: lifo.push(node.left) node = node.left continue prev = node while True: if node is None: break print node.value prev = node node = lifo.pop() node = prev if node.right is not None: lifo.push(node.right) node = node.right else: break The inner while-loop just doesn't feel right. Also, some of the elements are getting printed twice; may be I can solve this by checking if that node has been printed before, but that requires another variable, which, again, doesn't feel right. Where am I going wrong? I haven't tried postorder traversal, but I guess it's similar and I will face the same conceptual blockage there, too. Thanks for your time! P.S.: Definitions of Lifo and Node: class Node: def __init__(self, value, left=None, right=None): self.value = value self.left = left self.right = right class Lifo: def __init__(self): self.lifo = () def push(self, data): self.lifo = (data, self.lifo) def pop(self): if len(self.lifo) == 0: return None ret, self.lifo = self.lifo return ret

  • How to generate a key for a group entity?

    - by user246114
    Hi, I'm trying to make a group entity. Something like: class User { } class UserColor { } ... Key key = new KeyFactory.Builder( User.class.getSimpleName(), username). .addChild(UserColor.class.getSimpleName(), ???).getKey(); I know the unique username up-front to use for the key of the User object. But I just want app engine to generate a random unique value for the key value of the UserColor instance. I think this is described here, but I don't understand their wording: http://code.google.com/appengine/docs/java/datastore/transactions.html To create an object with a system-generated numeric ID and an entity group parent, you must use an entity group parent key field (such as customerKey, above). Assign the key of the parent to the parent key field, then leave the object's key field set to null. When the object is saved, the datastore populates the key field with the complete key, including the entity group parent. and this is their example: @Persistent @Extension(vendorName="datanucleus", key="gae.parent-pk", value="true") private Key customerKey; but I don't understand - should UserColor look like this then?: class UserColor { @Persistent @Extension(vendorName="datanucleus", key="gae.parent-pk", value="true") private Key mKeyParent; @Primary private Key mKey; // leave null } ... Key keyParent = new KeyFactory.Builder( User.class.getSimpleName(), username); UserColor uc = new UserColor(); uc.setKeyParent(keyParent); pm.makePersistent(uc); // now generated for me automatically? is that correct? Using this method, I should be able to use a User and a UserColor object in a transaction together, right? Thanks

  • python calendar to calculate month backwards

    - by Suhail
    Hi, we are trying to create a calendar function in python. we have created a small content management system, the requirement is, there will be a drop down list on the top right hand corner of the website, which will give the options - Months - 1 month, 2 months, 3 months and so on..., if the user selects 8 months then it should show the postscount for the last 8 months. the issue is we tried to write a small code which would do the month calculations, but the bug is that it does not consider the months beyond the current year, it shows the postscount only for months of the current year. for example: if the user selects 3 months, it will show the count for the l 3 months i.e present month and the previous 2 months, but if the user selects option more than 4 months, it does not consider the months from previous year, it still shows the month of the present year only. I am pasting the code below:- def __getSpecifiedMailCount__(request, value): dbconnector= DBConnector() CdateList= "select cdate from mail_records" DateNow= datetime.datetime.today() DateNow= DateNow.strftime("%Y-%m") DateYear= datetime.datetime.today() DateYear= DateYear.strftime("%Y") DateMonth= datetime.datetime.today() DateMonth= DateMonth.strftime("%m") #print DateMonth def getMonth(value): valueDic= {"01": "Jan", "02": "Feb", "03": "Mar", "04": "Apr", "05": "May", "06": "Jun", "07": "Jul", "08": "Aug", "09": "Sep", "10": "Oct", "11": "Nov", "12": "Dec"} return valueDic[value] def getMonthYearandCount(yearmonth): MailCount= "select count(*) as mailcount from mail_records where cdate like '%s%s'" % (yearmonth, "%") MailCountResult= MailCount[0]['mailcount'] return MailCountResult MailCountList= [] MCOUNT= getMonthYearandCount(DateNow) MONTH= getMonth(DateMonth) MailCountDict= {} MailCountDict['monthyear']= MONTH + ' ' + DateYear MailCountDict['mailcount']= MCOUNT var_monthyear= MONTH + ' ' + DateYear var_mailcount= MCOUNT MailCountList.append(MailCountDict) i=1 k= int(value) hereMONTH= int(DateMonth) while (i < k): hereMONTH= int(hereMONTH) - 1 if (hereMONTH < 10): hereMONTH = '0' + str(hereMONTH) if (hereMONTH == '00') or (hereMONTH == '0-1'): break else: PMONTH= getMonth(hereMONTH) hereDateNow= DateYear + '-' + PMONTH hereDateNowNum= DateYear + '-' + hereMONTH PMCOUNT= getMonthYearandCount(hereDateNowNum) MailCountDict= {} MailCountDict['monthyear']= PMONTH + ' ' + DateYear MailCountDict['mailcount']= PMCOUNT var_monthyear= PMONTH + ' ' + DateYear var_mailcount= PMCOUNT MailCountList.append(MailCountDict) i = i + 1 #print MailCountList MailCountDict= {'monthmailcount': MailCountList} reportdata = MailCountDict['monthmailcount'] #print reportdata return render_to_response('test.html', locals())

  • JS encodeURIComponent result different from the one created by FORM

    - by Marco Demaio
    I thought values entered in forms are properly encoded by browsers. But this simple test shows it's not true: <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html><head> <meta http-equiv="Content-Type" content="text/html; charset=windows-1252"> <title></title> </head><body> <form id="test" action="test_get_vs_encodeuri.html" method="GET" onsubmit="alert(encodeURIComponent(this.one.value));"> <input name="one" type="text" value="Euro-€"> <input type="submit" value="SUBMIT"> </form> </body></html> When hitting submit button: encodeURICompenent encodes input value into "Euro-%E2%82%AC" while browser into the GET query writes only a simple "Euro-%80" Could somone explain? Or is encodeURIComponent doing unnecessary conversions?

  • using jquery to add tr

    - by user306472
    I added a jquery function to add a <tr> dynamically at the end of my table. It worked fine until I added table headers to my table. After I did this, the function started adding 2 trs at a time to the table. What happened? HTML: <table id="table" border="0"> <th>Col 1</th><th>Col2</th><th>col3</th> <tbody> <tr> <td> <select> <option value ="one">one</option> <option value="two">two</option> </select> </td> <td> <input type="text"></input> </td> <td> <input type="text"></input> </td> </tr> </tbody> </table> JQuery code: $(function(){ $('a#add').click(function(){ $('#table > tbody').append('<tr><td><select><option value ="one">one</option><option value="two">two</option></select></td><td><input type="text"></input></td><td><input type="text"></input></td></tr>'); });

  • Database not updating after UPDATE SQL statement in ASP.net

    - by Ronnie
    I currently have a problem attepting to update a record within my database. I have a webpage that displays in text boxes a users details, these details are taken from the session upon login. The aim is to update the details when the user overwrites the current text in the text boxes. I have a function that runs when the user clicks the 'Save Details' button and it appears to work, as i have tested for number of rows affected and it outputs 1. However, when checking the database, the record has not been updated and I am unsure as to why. I've have checked the SQL statement that is being processed by displaying it as a label and it looks as so: UPDATE [users] SET [email]=@email, [firstname]=@firstname, [lastname]=@lastname, [promo]=@promo WHERE ([users].[user_id] = 16) The function and other relevant code is: Sub Button1_Click(sender As Object, e As EventArgs) changeDetails(emailBox.text, firstBox.text, lastBox.text, promoBox.text) End Sub Function changeDetails(ByVal email As String, ByVal firstname As String, ByVal lastname As String, ByVal promo As String) As Integer Dim connectionString As String = "Provider=Microsoft.Jet.OLEDB.4.0; Ole DB Services=-4; Data Source=C:\Documents an"& _ "d Settings\Paul Jarratt\My Documents\ticketoffice\datab\ticketoffice.mdb" Dim dbConnection As System.Data.IDbConnection = New System.Data.OleDb.OleDbConnection(connectionString) Dim queryString As String = "UPDATE [users] SET [email]=@email, [firstname]=@firstname, [lastname]=@lastname, "& _ "[promo]=@promo WHERE ([users].[user_id] = " + session.contents.item("ID") + ")" Dim dbCommand As System.Data.IDbCommand = New System.Data.OleDb.OleDbCommand dbCommand.CommandText = queryString dbCommand.Connection = dbConnection Dim dbParam_email As System.Data.IDataParameter = New System.Data.OleDb.OleDbParameter dbParam_email.ParameterName = "@email" dbParam_email.Value = email dbParam_email.DbType = System.Data.DbType.[String] dbCommand.Parameters.Add(dbParam_email) Dim dbParam_firstname As System.Data.IDataParameter = New System.Data.OleDb.OleDbParameter dbParam_firstname.ParameterName = "@firstname" dbParam_firstname.Value = firstname dbParam_firstname.DbType = System.Data.DbType.[String] dbCommand.Parameters.Add(dbParam_firstname) Dim dbParam_lastname As System.Data.IDataParameter = New System.Data.OleDb.OleDbParameter dbParam_lastname.ParameterName = "@lastname" dbParam_lastname.Value = lastname dbParam_lastname.DbType = System.Data.DbType.[String] dbCommand.Parameters.Add(dbParam_lastname) Dim dbParam_promo As System.Data.IDataParameter = New System.Data.OleDb.OleDbParameter dbParam_promo.ParameterName = "@promo" dbParam_promo.Value = promo dbParam_promo.DbType = System.Data.DbType.[String] dbCommand.Parameters.Add(dbParam_promo) Dim rowsAffected As Integer = 0 dbConnection.Open Try rowsAffected = dbCommand.ExecuteNonQuery Finally dbConnection.Close End Try labelTest.text = rowsAffected.ToString() if rowsAffected = 1 then labelSuccess.text = "* Your details have been updated and saved" else labelError.text = "* Your details could not be updated" end if End Function Any help would be greatly appreciated.

  • How to access CSS generated content with JavaScript

    - by Boldewyn
    I generate the numbering of my headers and figures with CSS's counter and content properties: img.figure:after { counter-increment: figure; content: "Fig. " counter(section) "." counter(figure); } This (appropriate browser assumed) gives a nice labelling "Fig. 1.1", "Fig. 1.2" and so on following any image. Question: How can I access this from Javascript? The question is twofold in that I'd like to access either the current value of a certain counter (at a certain DOM node) or the value of the CSS generated content (at a certain DOM node) or, obviously, both information. Background: I'd like to append to links back-referencing to figures the appropriate number, like this: <a href="#fig1">see here</h> ------------------------^ " (Fig 1.1)" inserted via JS As far as I can see, it boils down to this problem: I could access content or counter via getComputedStyle: var fig_content = window.getComputedStyle( document.getElementById('fig-a'), ':after').content; However, this is not the live value, but the one declared in the stylesheet. I cannot find any interface to access the real live value.

  • jQuery Validate plugin - password check - minimum requirements - Regex

    - by QviXx
    I've got a little problem with my password-checker. There's got a registration form with some fields. I use jQuery Validate plugin to validate user-inputs. It all works except the password-validation: The password should meet some minimum requirements: minimum length: 8 - I just use 'minlength: 8' at least one lower-case character at least one digit Allowed Characters: A-Z a-z 0-9 @ * _ - . ! At the moment I use this code to validate the password: $.validator.addMethod("pwcheck", function(value, element) { return /^[A-Za-z0-9\d=!\-@._*]+$/.test(value); }); This Code works for the allowed characters but not for minimum requirements. I know that you can use for example (?=.*[a-z]) for a lower-case-requirement. But I just don't get it to work. If I add (?=.*[a-z]) the whole code doesn't work anymore. I need to know how to properly add the code to the existing one. Thank you for your answers! This is the complete code <script> $(function() { $("#regform").validate({ rules: { forename: { required: true }, surname: { required: true }, username: { required: true }, password: { required: true, pwcheck: true, minlength: 8 }, password2: { required: true, equalTo: "#password" }, mail1: { required: true, email: true }, mail2: { required: true, equalTo: "#mail1" } }, messages: { forename: { required: "Vornamen angeben" }, surname: { required: "Nachnamen angeben" }, username: { required: "Usernamen angeben" }, password: { required: "Passwort angeben", pwcheck: "Das Passwort entspricht nicht den Kriterien!", minlength: "Das Passwort entspricht nicht den Kriterien!" }, password2: { required: "Passwort wiederholen", equalTo: "Die Passwörter stimmen nicht überein" }, mail1: { required: "Mail-Adresse angeben", email: "ungültiges Mail-Format" }, mail2: { required: "Mail-Adresse wiederholen", equalTo: "Die Mail-Adressen stimmen nicht überein" } } }); $.validator.addMethod("pwcheck", function(value, element) { return /^[A-Za-z0-9\d=!\-@._*]+$/.test(value); }); }); </script>
