  • .NET C# how to loop through some lable to set their attribute

    - by sydney wynn
    How do I do this in a loop. protected void ddlTool_SelectedIndexChanged(object sender, EventArgs e) { lblTool1.Visible = false; txtTool1.Visible = false; lblTool2.Visible = false; txtTool2.Visible = false; lblTool3.Visible = false; txtTool3.Visible = false; lblTool4.Visible = false; txtTool4.Visible = false; lblTool5.Visible = false; if (ddlTool.SelectedValue == "1") { lblTool1.Visible = true; txtTool1.Visible = true; } if (ddlTool.SelectedValue == "2") { lblTool1.Visible = true; txtTool1.Visible = true; lblTool2.Visible = true; txtTool2.Visible = true; } if (ddlTool.SelectedValue == "3") { lblTool1.Visible = true; txtTool1.Visible = true; lblTool2.Visible = true; txtTool2.Visible = true; lblTool3.Visible = true; txtTool3.Visible = true; } if (ddlTool.SelectedValue == "4") { lblTool1.Visible = true; txtTool1.Visible = true; lblTool2.Visible = true; txtTool2.Visible = true; lblTool3.Visible = true; txtTool3.Visible = true; lblTool4.Visible = true; txtTool4.Visible = true; }

  • C++: ifstream::getline problem

    - by Jay
    I am reading a file like this: char string[256]; std::ifstream file( "file.txt" ); // open the level file. if ( ! file ) // check if the file loaded fine. { // error } while ( file.getline( string, 256, ' ' ) ) { // handle input } Just for testing purposes, my file is just one line, with a space at the end: 12345 My code first reads the 12345 successfully. But then instead of the loop ending, it reads another string, which seems to be a return/newline. I have saved my file both in gedit and in nano. And I have also outputted it with the Linux cat command, and there is no return on the end. So the file should be fine. Why is my code reading a return/newline? Thanks.

  • Selecting an element based on text and attribute of its sibling, using Xpath

    - by Adam Asham
    Looking at the document, the goal is to select the second cell from the second row, in the first table. I've created the following expression: //row/td[2]/text()[td[@class="identifier"]/span[text()="identifier"]] but it does not return any rows. Unfortunately I do not see what's wrong. To me, it looks alright. The expression should: select the text in the second cell in any row where the text of a span equals to "identifier" and the span is located in cell with a "identifier" class I'd appreciate it if you could point out what I'm doing wrong. Sample XML document: <?xml version="1.0"?> <html> <table class="first"> <tr> <td>row 1, cell 1</td> <td>row 1, cell 2</td> </tr> <tr> <td class="identifier"> <span>identifier</span> </td> <td> foo <span>ignore</span> bar </td> </tr> <tr> <td>row 3, cell 1</td> <td>row 3, cell 2</td> </tr> </table> <table class="second"> <tr> <td>row 1, cell 1</td> <td>row 1, cell 2</td> </tr> <tr> <td class="identifier"> <span>not an identifier</span> </td> <td> not a target </td> </tr> <tr> <td>row 3, cell 1</td> <td>row 3, cell 2</td> </tr> </table> </html>

  • ASP MVC 2: Regular expression attribute working on clientside but not on serverside

    - by wh0emPah
    [Required(ErrorMessage = "Date is required")] [RegularExpression(@"^(((0[1-9]|[12]\d|3[01])\/(0[13578]|1[02])\/((1[6-9]|[2-9]\d)\d{2}))|((0[1-9]|[12]\d|30)\/(0[13456789]|1[012])\/((1[6-9]|[2-9]\d)\d{2}))|((0[1-9]|1\d|2[0-8])\/02\/((1[6-9]|[2-9]\d)\d{2}))|(29\/02\/((1[6-9]|[2-9]\d)(0[48]|[2468][048]|[13579][26])|((16|[2468][048]|[3579][26])00))))$", ErrorMessage="Date is not valid must be like (dd/mm/jjjj)")] public DateTime Startdate{ get; set;} The client-side validation works perfectly. So it seems that JavaScript can successfully understand my regular expression. But when I do a postback, and the modelstate.Isvalid() gets called. My date isn't valid anymore. So I'm guessing that when .NET performs the matching with the regEx it doesn't match. My question: Why does this regular expression match on the client side but not on the server side?

  • jQuery Set Child CSS Attribute Problem

    - by Jascha
    I have a child element of a div named "bob" that's class is '.divTitle' <div id="bob"> <div class="divTitle"> <a href="#"> <h1>Title</h1> </a> </div> </div> I am trying to set the background color of "divTitle" to red but for the life of me can't get this to work. Right now I am trying two things... $('#bob').children('.divTitle')[0].css('background-color', '#0f0'); // assuming children is returning an array... and $('#bob').children('.divTitle').css('background-color', '#0f0'); neither with any success... can anyone tell me what I am missing here? Do I have to go deeper than ".children"?

  • XmlSerialize a custom collection with an Attribute

    - by roomaroo
    I've got a simple class that inherits from Collection and adds a couple of properties. I need to serialize this class to XML, but the XMLSerializer ignores my additional properties. I assume this is because of the special treatment that XMLSerializer gives ICollection and IEnumerable objects. What's the best way around this? Here's some sample code: using System.Collections.ObjectModel; using System.IO; using System.Xml.Serialization; namespace SerialiseCollection { class Program { static void Main(string[] args) { var c = new MyCollection(); c.Add("Hello"); c.Add("Goodbye"); var serializer = new XmlSerializer(typeof(MyCollection)); using (var writer = new StreamWriter("test.xml")) serializer.Serialize(writer, c); } } [XmlRoot("MyCollection")] public class MyCollection : Collection<string> { [XmlAttribute()] public string MyAttribute { get; set; } public MyCollection() { this.MyAttribute = "SerializeThis"; } } } This outputs the following XML (note MyAttribute is missing in the MyCollection element): <?xml version="1.0" encoding="utf-8"?> <MyCollection xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <string>Hello</string> <string>Goodbye</string> </MyCollection> What I want is <MyCollection MyAttribute="SerializeThis" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <string>Hello</string> <string>Goodbye</string> </MyCollection> Any ideas? The simpler the better. Thanks.

  • How to get XML element/attribute name in SQL Server 2005

    - by OG Dude
    Hi, I have a simple procedure in SQL Server 2005 which takes some XML as input. The element attributes correspond to field names in tables. I'd like to be able to determine <elementName>, <attribNameX> dynamically as to avoid having to hardcode them into the procedure. How can I do this? The XML looks like this: <ROOT> <elementName attribName1 = "xxx" attribName2 = "yyy"/> <elementName attribName1 = "aaa" attribName2 = "bbb"/> ... </ROOT> The stored procedure like this: CREATE PROC dbo.myProc ( @XMLInput varchar(1000) ) AS BEGIN SET NOCOUNT ON DECLARE @XMLDocHandle int EXEC sp_xml_preparedocument @XMLDocHandle OUTPUT, @XMLInput SELECT someTable.someCol FROM dbo.someTable JOIN OPENXML (@XMLDocHandle, '/ROOT/elementName',1) WITH (attrib1Name int, attrib2Name int) AS XMLData ON someTable.attribName1 = XMLData.attribName1 AND someTable.attribName2 = XMLData.attribName2 EXEC sp_xml_removedocument @XMLDocHandle END GO The question has been asked here before but maybe there is a cleaner solution. Additionally, I'd like to pass the tablename as a parameter as well - I read some stuff arguing that this is bad style - so what would be a good solution for having a dynamic tablename? Thanks a lot in advance, /David

  • Getting custom attribute from an Exception thrown during testing

    - by Amit Bhargava
    I'm using JUnit4 to test my code. Now, I'm aware that the following annotation allows me to expect an exception of a certain type @Test(expected = NipException.class) However, I have an 'errorCode' property in my exception class which I would also like to verify. This is because the same exception is thrown at three places in the same method with different error codes. How do I access 'errorCode' of the thrown exception?

  • JSF + PrimeFaces: `update` attribute does not update component

    - by Harry Pham
    Here is my layout <div id="mainPanel"> <div id="padding"> <h:outputText id="text" value="Personal Feed" rendered="#{Profile.renderComment}"/> </div> <div id="right"> <h:form> <p:commandButton value="Update" actionListener="#{bean.toggleComment}" update="text" /> </h:form> </div> </div> When I click the link Update, which suppose to toggle the renderComment boolean on and off, but it does not toggle the display of the text Personal Feed. Now if I put a form around the h:outputText, and instead update the form instead, then it work. Why is that?

  • ValidateInput Attribute Doesn't Seem To Work in ASP.NET MVC

    - by JC Grubbs
    I'm trying to get around the "potentially dangerous Request.Form value" error and I'm having no luck. Yes, yes, I've read all the other StackOverflow related questions and none of them seem to get me closer to an answer. I am using [ValidateInput(false)] on all related controller actions...and I've checked many times. I'm using ValidateRequest='false' in all the related ASPX views. I am using ASP.NET MVC 2 Preview 1, but I don't think that's an issue since the error is being generated lower in the framework; Page.ProcessRequest to be exact. I can't see anything I'm doing wrong, I even set <page validateRequest='false'> in the web.config and that didn't solve it either. HELP!!!!!

  • Why SQL2008 debugger would NOT step into a certain child stored procedure

    - by John Galt
    I'm encountering differences in T-SQL with SQL2008 (vs. SQL2000) that are leading me to dead-ends. I've verified that the technique of sharing #TEMP tables between a caller which CREATES the #TEMP and the child sProc which references it remain valid in SQL2008 See recent SO question. My core problem remains a critical "child" stored procedure that works fine in SQL2000 but fails in SQL2008 (i.e. a FROM clause in the child sProc is coded as: SELECT * FROM #AREAS A) despite #AREAS being created by the calling parent. Rather than post snippets of the code now, here is another symptom that may help you suggest something. I fired up the new debugger in SQL Mgmt Studio: EXEC dbo.AMS1 @S1='06',@C1='037',@StartDate='01/01/2008',@EndDate='07/31/2008',@Type=1,@ACReq = 1,@Output = 0,@NumofLines = 30,@SourceTable = 'P',@LoanPurposeCatg='P' This is a very large sProc and the key snippet that is weird is the following: **create table #Areas ( State char(2) , County char(3) , ZipCode char(5) NULL , CityName varchar(28) NULL , PData varchar(3) NULL , RData varchar(3) NULL , SMSA_CD varchar(10) NULL , TypeCounty varchar(50) , StateAbbr char(2) ) EXECUTE dbo.AMS_I_GetAreasV5 -- this child populates #Areas @SMSA = @SMSA , @S1 = @S1 , @C1 = @C1 , @Z1 = @Z1 , @SourceTable = @SourceTable , @CustomID = @CustomID , @UserName = @UserName , @CityName = @CityName , @Debug=0 EXECUTE dbo.AMS_I_GetAreas_FixAC -- this child cannot reference #Areas @StartDate = @StartDate , @EndDate = @EndDate , @SMSA_CD = @SMSA_CD , @S1 = @S1 , @C1 = @C1 , @Z1 = @Z1 , @CityName = @CityName , @CustomID = @CustomID , @Debug=0 -- continuation of the parent sProc** I can step through the execution of the parent stored procedure. When I get to the first child sproc above, I can either STEP INTO dbo.AMS_I_GetAreasV5 or STEP OVER its execution. When I arrive at the invocation of the 2nd child sProc - dbo.AMS_I_GetAreas_FixAC - I try to STEP INTO it (because that is where the problem statement is) and STEP INTO is ignored (i.e. treated like STEP OVER instead; yet I KNOW I pressed F11 not F10). It WAS executed however, because when control is returned to the statement after the EXECUTE, I click Continue to finish execution and the results windows shows the errors in the dbo.AMS_I_GetAreas_FixAC (i.e. the 2nd child) stored procedure. Is there a way to "pre-load" an sProc with the goal of setting a breakpoint on its entry so that I can pursue execution inside it? In summary, I wonder if the inability to step into a given child sproc might be related to the same inability of this particular child to reference a #temp created by its parent (caller).

  • C# Attribute XmlIgnore and XamlWriter class - XmlIgnore not working

    - by Horst Walter
    I have a class, containing a property Brush MyBrush marked as [XmlIgnore]. Nevertheless it is serialized in the stream causing trouble when trying to read via XamlReader. I did some tests, e.g. when changing the visibility (to internal) of the Property it is gone in the stream. Unfortunately I cannot do this in my particular scenario. Did anybody have the same issue and? Do you see any way to work around this? Remark: C# 4.0 as far I can tell This is a method from my Unit Test where I do test the XamlSerialization: // buffer to a StringBuilder StringBuilder sb = new StringBuilder(); XmlWriter writer = XmlWriter.Create(sb, settings); XamlDesignerSerializationManager manager = new XamlDesignerSerializationManager(writer) {XamlWriterMode = XamlWriterMode.Expression}; XamlWriter.Save(testObject, manager); xml = sb.ToString(); Assert.IsTrue(!String.IsNullOrEmpty(xml) && !String.IsNullOrEmpty(xml), "Xaml Serialization failed for " + testObject.GetType() + " no xml string available"); xml = sb.ToString(); MemoryStream ms = xml.StringToStream(); object root = XamlReader.Load(ms); Assert.IsTrue(root != null, "After reading from MemoryStream no result for Xaml Serialization"); In one of my classes I use the Property Brush. In the above code this Unit Tests fails because of a Brush object not serializable is the value. When I remove the Setter (as below, the Unit Test passes. Using the XmlWriter (basically same test as above) it works. In the StringBuffer sb I can see that Property Brush is serialized when the Setter is there and not when removed (most likely another check ignoring the Property because of no setter). Other Properties with [XmlIgnore] are ignored as intended. [XmlIgnore] public Brush MyBrush { get { ..... } // removed because of problem with Serialization // set { ... } }

  • Auto populate input based on file name with AngularJS

    - by LouieV
    I am playing around with AngularJS and have not been able to solve this problem. I have a view that has a form to upload a file to a node server. So far I have manage to do this using some directives and a service. I allow the user to send a custom name to the POST data if they desire. What I wan to accomplish is that when the user selects a file the filename models auto populates. My view looks like: <div> <input file-model="phpFile" type="file"> <input name="filename" type="text" ng-model="filename"> <button ng-click="send()">send</button> </div> file-model is my directive that allows the file to be assigned to a scope. myApp.directive('fileModel', ['$parse', function($parse) { return { restrict: 'A', link: function(scope, element, attrs) { var model = $parse.(attrs.fileModel); var modelSetter = model.assign; element.bind('change', function() { scope.$apply(function() { modelSetter(scope, element[0].files[0]); }); }); } }]); The service: myApp.service('fileUpload', ['$http', function($http){ this.uploadFileToUrl = function(file, uploadUrl, optionals) { var fd = new FormData(); fd.append('file', file); for (var key in file) { fd.append(key, file[key]); } for(var i = 0; i < optionals.length; i++){ fd.append(optionals[i].name, optionals[i].data); } }); }]); Here as you can see I pass the file, append its properties, and append any optional properties. In the controller is where I am having the troubles. I have tried $watch and using the file-model but I get the same error either way. myApp.controller('AddCtrl', function($scope, $location, PEberry, fileUpload){ //$scope.$watch(function() { // return $scope.phpFile; //},function(newValue, oldValue) { // $scope.filename = $scope.phpFile.name; //}, true); // if ($scope.phpFiles) { // $scope.filename = $scope.phpFiles.name; // } $scope.send = function() { var uploadUrl = "/files"; var file = $scope.phpFile; //var opts = [{ name: "uname", data: file.name }] fileUpload.uploadFileToUrl(file, uploadUrl); }; }); Thank you for your help!
