  • Buttons OnClick Event not firing when it causes a textboxes onChange event to fire first

    - by user48408
    I have a few textboxes and button to save their values on a webpage. The onchange event of the textboxes fires some js which adds the changed text to a js array. The ok button when clicked flushes this to the database via a webservice. This works fine except when the onchange event is caused by clicking the ok button. In this scenario the onchange of the textboxes still fires but the onClick event of the button does not. Any ideas? textboxes look something like <input name="ctrlJPView$tbcTabContainer$Details$JP_Details_Address2Text" type="text" value="test" id="ctrlJPView_tbcTabContainer_Details_JP_Details_Address2Text" onchange="addSaveDetails('Jobs###' + document.getElementById('ctrlJPView_tbcTabContainer_Details_JP_Details_Address2Text').value + ');" style="font-size:8pt;Left:110px;Top:29px;Width:420px;Height:13px;Position:absolute;" /> My save button <input type="button" name="ctrlJPView$btnOk" value="OK" onclick="saveAmendments();refreshJobGrids();return false;__doPostBack('ctrlJPView$btnOk','')" id="ctrlJPView_btnOk" class="ControlText" style="width:60px;" /> UPDATE: I guess this comes down to one of two things. 1) Something is happening before the onClick of the button gets called to surpress that call such as an inadvertent return false; or 2) the onClick event isn't firing at all. Now I've rem'd out everything actually inside the functions that are being called beforehand but the problem persists. But if i remove the call altogether it works (???)

  • Problem in print layout near page end

    - by Miraaj
    Hi all, I am facing some problem in print layout, below is the description of steps I followed and problem which I am facing: I have taken a custom view over which there are NSTextViews, NSTableViews arranged one below other. I am trying to calculate exact height of NSTextViews and NSTableViews depending upon content in them. Depending upon calculated height I am arranging them in super-custom view. Then I am printing the view, using this code : [self arrangeBriefLayoutDynamically]; // step 2nd and 3rd // setting fixed parameters for printing NSPrintInfo * printInfo = [NSPrintInfo sharedPrintInfo]; [printInfo setVerticallyCentered:NO]; [printInfo setRightMargin:12.0]; [printInfo setTopMargin:37.0]; [printInfo setLeftMargin:12.0]; [printInfo setHorizontallyCentered:YES]; [printInfo setHorizontalPagination:NSFitPagination]; [printInfo setVerticalPagination:NSAutoPagination]; [printInfo setPaperName:@"na-letter"]; [printInfo setOrientation:NSPortraitOrientation]; PMSetScale([printInfo PMPageFormat], 100.0); [NSPrintInfo setSharedPrintInfo:printInfo]; [briefCompleteView print:nil]; Problem is : when size of a table view or text view exceeds, such that it crosses the page boundary then SOMETIMES text near boundary appears improper i.e.. part of its height lies on first page and rest of it lies on second page. Click to check problem ! Can anyone suggest me some way to resolve it ? Thanks, Miraaj

  • C: lseek() related question.

    - by Andrei Ciobanu
    I want to write some bogus text in a file ("helloworld" text in a file called helloworld), but not starting from the beginning. I was thinking to lseek() function. If I use the following code: #include <unistd.h> #include <fcntl.h> #include <sys/stat.h> #include <sys/types.h> #include <stdlib.h> #include <stdio.h> #define fname "helloworld" #define buf_size 16 int main(){ char buffer[buf_size]; int fildes, nbytes; off_t ret; fildes = open(fname, O_CREAT | O_TRUNC | O_WRONLY, S_IRUSR | S_IWUSR); if(fildes < 0){ printf("\nCannot create file + trunc file.\n"); } //modify offset if((ret = lseek(fildes, (off_t) 10, SEEK_END)) < (off_t) 0){ fprintf(stdout, "\nCannot modify offset.\n"); } printf("ret = %d\n", (int)ret); if(write(fildes, fname, buf_size) < 0){ fprintf(stdout, "\nWrite failed.\n"); } close(fildes); return (0); } , it compiles well and it runs without any apparent errors. Still if i : cat helloworld The output is not what I expected, but: helloworld Can Where is "Can" comming from, and where are my empty spaces ? Should i expect for "zeros" instead of spaces ? If i try to open helloworld with gedit, an error occurs, complaining that the file character encoding is unknown.

  • Using Build Manager Class to Load ASPX Files and Populate its Controls

    - by Sandhurst
    I am using BuildManager Class to Load a dynamically generated ASPX File, please note that it does not have a corresponding .cs file. Using Following code I am able to load the aspx file, I am even able to loop through the control collection of the dynamically created aspx file, but when I am assigning values to controls they are not showing it up. for example if I am binding the value "Dummy" to TextBox control of the aspx page, the textbox remains empty. Here's the code that I am using protected void Page_Load(object sender, EventArgs e) { LoadPage("~/Demo.aspx"); } public static void LoadPage(string pagePath) { // get the compiled type of referenced path Type type = BuildManager.GetCompiledType(pagePath); // if type is null, could not determine page type if (type == null) throw new ApplicationException("Page " + pagePath + " not found"); // cast page object (could also cast an interface instance as well) // in this example, ASP220Page is a custom base page System.Web.UI.Page pageView = (System.Web.UI.Page)Activator.CreateInstance(type); // call page title pageView.Title = "Dynamically loaded page..."; // call custom property of ASP220Page //pageView.InternalControls.Add( // new LiteralControl("Served dynamically...")); // process the request with updated object ((IHttpHandler)pageView).ProcessRequest(HttpContext.Current); LoadDataInDynamicPage(pageView); } private static void LoadDataInDynamicPage(Page prvPage) { foreach (Control ctrl in prvPage.Controls) { //Find Form Control if (ctrl.ID != null) { if (ctrl.ID.Equals("form1")) { AllFormsClass cls = new AllFormsClass(); DataSet ds = cls.GetConditionalData("1"); foreach (Control ctr in ctrl.Controls) { if (ctr is TextBox) { if (ctr.ID.Contains("_M")) { TextBox drpControl = (TextBox)ctr; drpControl.Text = ds.Tables[0].Rows[0][ctr.ID].ToString(); } else if (ctr.ID.Contains("_O")) { TextBox drpControl = (TextBox)ctr; drpControl.Text = ds.Tables[1].Rows[0][ctr.ID].ToString(); } } } } } } }

  • Linq-to-sql Add item and a one-to-many record at once

    - by Oskar Kjellin
    I have a function where I can add articles and users can comment on them. This is done with a one to many relationship like= "commentId=>ArticleId". However when I try to add the comment to the database at the same time as I add the one to many record, the commentId is not known. Like this code: Comment comment = new Comment(); comment.Date = DateTime.UtcNow; comment.Text = text; comment.UserId = userId; db.Comments.InsertOnSubmit(comment); comment.Articles.Add(new CommentsForArticle() { ArticleId = articleId, CommentId = comment.CommentId }); The commentId will be 0 before i press submit. Is there any way arround not having to submit in between or do I simply have to cut out the part where I have a one-to-many relationship and just use a CommentTable with a column like "ArticleId". What is best in a performance perspective? I understand the underlying issue, I just want to know which solution works best.

  • Check if UINavigationItem title is truncated

    - by PartiallyFinite
    I want to check whether the title of a UINavigationItem is truncated. I set the title like this: self.navigationItem.title = whatever. I know I can check if the text in a UILabel is truncated like this: CGSize size = [label.text sizeWithFont:[UIFont fontWithName:@"myfont" size:18.0]]; if (size.width > label.bounds.size.width) { // set a shorter title } And I can even find the UINavigationItemView object in which the title is displayed like so: UIView *navItemView; for (UIView *view in self.navigationController.navigationBar.subviews) { if ([view isKindOfClass:NSClassFromString(@"UINavigationItemView")]) { navItemView = view; } } But I cannot apply this method to the navItemView because is always seems to have a width of exactly 58, which is much less than the title in it, so according to that, it would appear that the title is truncated, even when it isn't. So, my question comes down to this: How do I find the width of the title displayed in the UINavigationItem? UPDATE: I have found a solution to my problem, but it isn't exactly ideal, perfect, or reliable, so I am not marking it as an answer yet. If anyone has any better solutions, please share them.

  • Problem consuming Exchange Web Service 2010 with jax-ws metro

    - by Johan Karlberg
    I am trying to consume the Exchange 2010 Web Service interface using JAX-WS. I'm using JAX-WS 2.2 RI (Metro 2.0). 2.1 exhibited the same problem. I am running into trouble with Exchange, which returns "HTTP/1.1 415 Cannot process the message because the content type 'text/xml;charset=utf-8' was not the expected type 'text/xml; charset=utf-8'." as a reponse (2.1 quoted the charset value, otherwise same response). Apparently I need to dictate the exact Content-type header for Exchange to be happy. Is there a way for me to do this without forcing me to manually rebuild the dependency? I currently rely on published maven artifacts, and would like to continue doing this if at all possible. The consuming process is a regular J2SE app, with no containers in sight. I have control of the application and can add pretty much anything required to the applications scope, but can not add out-of-process items like proxy servers. The client classes were generated from local WSDL, but the charset specification is derived from constants declared in the jaxws RI implementation, not the generated code. The resulting HTTP transport is thus handled by the standard http/https client from Sun JRE5 or JRE6.

  • Dojox Datagrid contains data, but shows up as empty

    - by Vivek
    I'd really appreciate any help on this. There is this Dojox Datagrid that I'm creating programatically and supplying JSON data. As of now, I'm creating this data within JavaScript itself. Please refer to the below code sample. var upgradeStageStructure =[{ cells:[ { field: "stage", name: "Stage", width: "50%", styles: 'text-align: left;' }, { field:"status", name: "Status", width: "50%", styles: 'text-align: left;' } ] }]; var upgradeStageData = [ {id:1, stage: "Preparation", status: "Complete"}, {id:2, stage: "Formatting", status: "Complete"}, {id:3, stage: "OS Installation", status: "Complete"}, {id:4, stage: "OS Post-Installation", status: "In Progress"}, {id:5, stage: "Application Installation", status: "Not Started"}, {id:6, stage: "Application Post-Installation", status: "Not Started"} ]; var stagestore = new dojo.data.ItemFileReadStore({data:{identifier:"id", items: upgradeStageData}}); var upgradeStatusGrid = new dojox.grid.DataGrid({ autoHeight: true, style: "width:400px;padding:0em;margin:0em;", store: stagestore, clientSort: false, rowSelector: '20px', structure: upgradeStageStructure, columnReordering: false, selectable: false, singleClickEdit: false, selectionMode: 'none', loadingMessage: 'Loading Upgrade Stages', noDataMessage:'There is no data', errorMessage: 'Failed to load Upgrade Status' }); dojo.byId('progressIndicator').innerHTML=''; dojo.byId('progressIndicator').appendChild(upgradeStatusGrid.domNode); upgradeStatusGrid.startup(); The problem is that I am not seeing anything within the grid upon display (no headers, no data). But I know for sure that the data in the grid does exist and the grid is properly initialized, because I called alert (grid.domNode.innerHTML);. The resultant HTML that is thrown up does show a table containing header rows and the above data. This link contains an image which illustrates what I'm seeing when I display the page. (Can't post images since my account is new here) As you may notice, there are 6 rows for 6 pieces of data I have created but the grid is a mess. Please help out if you think you know what could be going wrong. Thanks in advance, Viv

  • Find actual value of PHP variable

    - by Simon S
    Hi all. I am having a real headache with reading in a tab delimited text file and inserting it into a MySQL Database. The tab delimited text file was generated (I think) from a MS SQL Database, and I have written a simple script to read in the file and insert it into an existing table in my MySQL database. However, there seems to be some problem with the data in the txt file. When my PHP script parses the file and I output the INSERT statements, the values in each of the fields are longer than they should be. For example, the first field should be a simple two character alphanumeric value. If I echo out the INSERT statements, using Firebug (in Firefox), between each of the characters is a question mark in a black diamond. If I var_dump the values, I get the following: string(5) "A1" Now, this clearly shows a two character string, but var_dump tells me it is five characters long!! If I trim() the value, all I get is the first character (in this case "A"). How can I get at the other characters, even if it is only to remove them? Additionally, this appears to be forcing MySQL to insert the value as a BLOB, not as a varchar as it should. Simon

  • QueryReadStore loads JSON into DataGrid, but JsonRestStore does not (from the same source)

    - by labratmatt
    I'm building a Dojo DataGrid from JSON data provided by my REST interface. The DataGrid loads the data fine using a QueryReadStore, but doesn't seem to work with the same same data piped into a JsonRestStore. I'm using the following Dojo libs with Dojo 1.4.1: dojo.require("dojox.data.JsonRestStore"); dojo.require("dojox.grid.DataGrid"); dojo.require("dojox.data.QueryReadStore"); dojo.require("dojo.parser"); I declare my stores in the following manner: var storeJRS = new dojox.data.JsonRestStore({target:"api/collaborations.php/1", idAttribute: 'items[].id'}); var storeQRS = new dojox.data.QueryReadStore({url:"api/collaborations.php/1", requestMethod:"get"}); I create my grid layout like this: var gridLayout = [ new dojox.grid.cells.RowIndex({ name: "Row #", width: 5, styles: "text-align: left;" }), { name: "Name", field: "name", styles: "text-align:right;", width:20 }, { name: "Description", field: "description", width:30 } ]; I create my DataGrid as follows: The above works, but if I use QueryReadStore as my store, the grid is created with the headers (Name, Description), but it isn't populated with any rows: <div dojoType="dojox.grid.DataGrid" jsid="grid3" store="storeQRS" structure="gridLayout" style="height:500px; width:1000px;"></div> Using FireBug, I can see that QueryReadStore is getting my JSON data from my REST interface. It looks like the following: {"numRows":6,"items":[{"name":"My Super Cool Collab","description":"This is for all the super cool people in the super cool group","id":1},{"name":"My Other Super Cool","description":"This is for all the other super cool people","id":3},{"name":"This is another coll","description":"This is just some other collab","id":4},{"name":"some new collab","description":"this is a new collab","id":5},{"name":"yet another new coll","description":"uh huh","id":6},{"name":"asdf","description":"asdf","id":7}]} Any ideas? Thanks.

  • .NET RichTextBox: unable to change Rtf property.

    - by Dave
    Hey guys, Perhaps I'm missing something real simple here, but I've been struggling to change the RTF property of my RichTextBox in order to apply some color coding to my text. Probably the most straight-forward example of the problem I'm having is setting the Rtf property to include a color table in its header. The default RTF string returned by the Rtf property: {\rtf1\ansi\ansicpg1252\deff0\deflang1033{\fonttbl{\f0\fnil\fcharset0 Microsoft Sans Serif;}}\viewkind4\uc1\pard\f0\fs17\par} And the new RTF string I'd like to set with my color table: {\rtf1\ansi\ansicpg1252\deff0\deflang1033{\fonttbl{\f0\fnil\fcharset0 Microsoft Sans Serif;}{\colortbl;\red128\green0\blue0;\red0\green128\blue0;\red0\green0\blue255;}}\viewkind4\uc1\pard\f0\fs17\par} And I set this using: RichTextBox richTextBox = new RichTextBox(); richTextBox.Rtf = rtfStr; // My new RTF string, as seen above. However, via debugger, it can be observed the that Rtf property stubbornly refuses to change; no exceptions are thrown, it just refuses to change. Same issue happens when I string.Replace() words to include RTF color tags around them. I've also tried turning off any ReadOnly properties on the text box. Any suggestions would be most helpful, thanks! Dave

  • In Java, howd do I iterate through lines in a textfile from back to front

    - by rogue780
    Basically I need to take a text file such as : Fred Bernie Henry and be able to read them from the file in the order of Henry Bernie Fred The actual file I'm reading from is 30MB and it would be a less than perfect solution to read the whole file, split it into an array, reverse the array and then go from there. It takes way too long. My specific goal is to find the first occurrence of a string (in this case it's "InitGame") and then return the position beginning of the beginning of that line. I did something like this in python before. My method was to seek to the end of the file - 1024, then read lines until I get to the end, then seek another 1024 from my previous starting point and, by using tell(), I would stop when I got to the previous starting point. So I would read those blocks backwards from the end of the file until I found the text I was looking for. So far, I'm having a heck of a time doing this in Java. Any help would be greatly appreciated and if you live near Baltimore it may even end up with you getting some fresh baked cookies. Thanks!

I have a custom UserControl with a Panel that contains a a couple Labels, both .aspx controls. .aspx: <asp:Panel runat="server"> <asp:Label ID="label1" runat="server"> </asp:Label> </asp:Panel> <asp:Panel runat="server"> <asp:Label ID="label2" runat="server"> </asp:Label> </asp:Panel> Codebehind: private readonly Object object; protected void Page_Load(object sender, EventArgs e) { // These are the lines that are failing // label1 and label2 are null label1.Text = object.Value1; label2.Text = object.Value2; } public ObjectRow(Object objectToDisplay) { object = objectToDisplay; } On another page, in the code behind, I create a new instance of the custom user control. protected void Page_Load(object sender, EventArgs e) { CustomControl control = new CustomControl(object); } The user control takes the parameter and attempts to set the labels based off of the object passed in. The labels that it tries to assign the values to are however, null. Is this an ASP.net lifecycle issue that I'm not understanding? My understanding based on the Microsoft ASP.net lifecycle page was that page controls were available after the Page_Initialization. What is the proper way to do this? Is there a better way?

  • Binding UpdateSourceTrigger=Explicit, updates source at program startup

    - by GTD
    I have following code: <Window x:Class="WpfApplication1.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Window1" Height="300" Width="300"> <Grid> <TextBox Text="{Binding Path=Name, Mode=OneWayToSource, UpdateSourceTrigger=Explicit, FallbackValue=default text}" KeyUp="TextBox_KeyUp" x:Name="textBox1"/> </Grid> public partial class Window1 : Window { public Window1() { InitializeComponent(); } private void TextBox_KeyUp(object sender, KeyEventArgs e) { if (e.Key == Key.Enter) { BindingExpression exp = this.textBox1.GetBindingExpression(TextBox.TextProperty); exp.UpdateSource(); } } } public class ViewModel { public string Name { set { Debug.WriteLine("setting name: " + value); } } } public partial class App : Application { protected override void OnStartup(StartupEventArgs e) { base.OnStartup(e); Window1 window = new Window1(); window.DataContext = new ViewModel(); window.Show(); } } I want to update source only when "Enter" key is pressed in textbox. This works fine. However binding updates source at program startup. How can I avoid this? Am I missing something?

  • How do you clear a CustomValidator Error on a Button click event?

    - by George
    I have a composite User control for entering dates: The CustomValidator will include server sided validation code. I would like the error message to be cleared via client sided script if the user alters teh date value in any way. To do this, I included the following code to hook up the two drop downs and the year text box to the validation control: <script type="text/javascript"> ValidatorHookupControlID("<%= ddlMonth.ClientID%>", document.getElementById("<%= CustomValidator1.ClientID%>")); ValidatorHookupControlID("<%= ddlDate.ClientID%>", document.getElementById("<%= CustomValidator1.ClientID%>")); ValidatorHookupControlID("<%= txtYear.ClientID%>", document.getElementById("<%= CustomValidator1.ClientID%>")); </script> However, I would also like the Validation error to be cleared when the user clicks the clear button. When the user clicks the Clear button, the other 3 controls are reset. To avoid a Post back, the Clear button is a regular HTML button with an OnClick event that resets the 3 controls. Unfortunately, the ValidatorHookupControlID method does not seem to work on HTML controls, so I thought to change the HTML Button to an ASP button and to Hookup to that control instead. However, I cannot seem to eliminate the Postback functionality associated by default with the ASP button control. I tried to set the UseSubmitBehavior to False, but it still submits. I tried to return false in my btnClear_OnClick client code, but the code sent to the browser included a DoPostback call after my call. btnClear.Attributes.Add("onClick", "btnClear_OnClick();") Instead of adding OnClick code, I tried overwriting it, but the DoPostBack code was still included in the final code that was sent to the browser. What do I have to do to get the Clear button to clear the CustomValidator error when clicked and avoid a postback? btnClear.Attributes.Item("onClick") = "btnClear_OnClick();"

  • Silverlight databinding error

    - by Petezah
    I found an example online that explains how to perform databinding to a ListBox control using LINQ in WPF. The example works fine but when I replicate the same code in Silverlight it doesn't work. Is there a fundamental difference between Silverlight and WPF that I'm not aware of? Here is an Example of the XAML: <ListBox x:Name="listBox1"> <ListBox.ItemTemplate> <DataTemplate> <StackPanel> <TextBlock Text="{Binding Name}" FontSize="18"/> <TextBlock Text="{Binding Role}" /> </StackPanel> </DataTemplate> </ListBox.ItemTemplate> </ListBox> Here is an example of my code behind: private void UserControl_Loaded(object sender, RoutedEventArgs e) { string[] names = new string[] { "Captain Avatar", "Derek Wildstar", "Queen Starsha" }; string[] roles = new string[] { "Hero", "Captain", "Queen of Iscandar" }; listBox1.ItemSource = from n in names from r in roles select new { Name = n, Role = r} }

  • What are the security implications of making a clientaccesspolicy proxy workaround?

    - by Edward Tanguay
    I wanted to use a published GoogleDocs document as the datasource of a Silverlight application but ran into clientaccesspolicy issues. I read many articles like this and this about how difficult it is to get around the clientaccesspolicy issue. So I wrote this 15-line CURL script and put it on my PHP site and now I can get the text of any GoogleDocs document and any text from any URL into my Silverlight application: <?php $url = filter_input(INPUT_GET, 'url',FILTER_SANITIZE_STRING); $user_agent = 'Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)'; $ch = curl_init(); curl_setopt($ch, CURLOPT_COOKIEJAR, "/tmp/cookie"); curl_setopt($ch, CURLOPT_COOKIEFILE, "/tmp/cookie"); curl_setopt($ch, CURLOPT_URL, $url ); // set url to post to curl_setopt($ch, CURLOPT_FAILONERROR, 1); // Fail on errors curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 0); // allow redirects curl_setopt($ch, CURLOPT_RETURNTRANSFER,1); // return into a variable curl_setopt($ch, CURLOPT_TIMEOUT, 15); curl_setopt($ch, CURLOPT_USERAGENT, $user_agent); curl_setopt($ch, CURLOPT_VERBOSE, 0); echo curl_exec($ch); ?> So it makes me wonder: Why is there so much discussion about whether or not URLs support clientaccesspolicy or not, since you just have to write a simple proxy script and get the information through it? Why aren't there services, e.g. like the URL shortening services, which supply this functionality? What are the security implications of having a script like this?

  • Prompt User before browser close?

    - by JM4
    We have an administrative portal that our teachers constantly forget to download their latest PDF instructions before logging out and/or closing the browser window. I have looked around but can't find what I'm looking for. I want to accomplish the following goals: Goal 1 Before a user can close the browser window, they are prompted "Did you remember to download your form?" with two options, yes/no. If yes, close, if no, return to page. Goal 2 Before a user can click the 'logout' button, they are prompted with the same as above. My first pass at the very basic code (which does not work for browser close) is: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Untitled Document</title> <script type="text/javascript"> function init() { if(window.addEventListener) { window.addEventListener("beforeunload", unloadMess, false); } else if(window.onbeforeunload) { window.onbeforeunload = unloadMess; }; } function unloadMess() { var User_Message = "[Your user message here]" return User_Message; } </script> </head> <body onload="init();"> hello this is my site </body> </html> anybody ever come across a good solution?
