  • ObjectDisposedException from core .NET code

    - by John
    I'm having this issue with a live app. (Unfortunately this is post-mortem debugging - I only have this stack trace. I've never seen this personally, nor am I able to reproduce). I get this Exception: message=Cannot access a disposed object. Object name: 'Button'. exceptionMessage=Cannot access a disposed object. Object name: 'Button'. exceptionDetails=System.ObjectDisposedException: Cannot access a disposed object. Object name: 'Button'. at System.Windows.Forms.Control.CreateHandle() at System.Windows.Forms.Control.get_Handle() at System.Windows.Forms.Control.PointToScreen(Point p) at System.Windows.Forms.Button.OnMouseUp(MouseEventArgs mevent) at System.Windows.Forms.Control.WmMouseUp(Message& m, MouseButtons button, Int32 clicks) at System.Windows.Forms.Control.WndProc(Message& m) at System.Windows.Forms.ButtonBase.WndProc(Message& m) at System.Windows.Forms.Button.WndProc(Message& m) at System.Windows.Forms.Control.ControlNativeWindow.OnMessage(Message& m) at System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m) at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam) exceptionSource=System.Windows.Forms exceptionTargetSite=Void CreateHandle() It looks like a mouse event is arriving at a form after the form has been disposed. Note there is none of my code in this stack trace. The only weird (?) thing I'm doing, is that I do tend to Dispose() Forms quite aggressively when I use them with ShowModal() (see "Aside" below). But I only do this after ShowModal() has returned (that should be safe right)? I think I read that events might be queued up in the event queue, but I can't believe this would be the problem. I mean surely the framework must be tolerant to old messages? I can well imagine that under stress messages might back-log and surely the window might go away at any time? Any ideas? If you could even suggest ways of reproducing, that might be useful. John Aside: TBH I've never quite understood whether calling Dispose() after Form.ShowDialog() is strictly necessary - the MSDN docs for ShowDialog() are to my mind a bit ambiguous.

  • Import CSV into Org-mode properties

    - by lecodesportif
    I would like to import a CSV into Org-mode. Others have already asked about importing CSV to Org-mode tables. That's not what I am trying to do. I need to import CSV to Org-mode properties. For example, a CSV like this: Name,Tel,Mobile,Fax John,11111,22222,33333 should become: :PROPERTIES: :Name: John :Tel: 11111 :Mobile: 22222 :Fax: 33333 :END: Do you happen to know a painless way to do it?

  • XSLT 1.0 grouping to reformat element defined by date into element defined by task

    - by Daniel
    Hi folks, I have a tricky XSLT transformation and I'd like your advise My xml is formatted as below: <Person> <name>John</name> <date>June12</date> <workTime taskID=1>34</workTime> <workTime taskID=2>12</workTime> </Person> <Person> <name>John</name> <date>June12</date> <workTime taskID=1>21</workTime> <workTime taskID=2>11</workTime> </Person> The output xml should be: <Person> <name>John</name> <taskID>1</taskID> <workTime> <date>June12</date> <time>34</time> </worTime> <workTime> <date>June13</date> <time>21</time> </worTime> </Person> <Person> <name>John</name> <taskID>2</taskID> <workTime> <date>June12</date> <time>12</time> </worTime> <workTime> <date>June13</date> <time>11</time> </worTime> </Person> Essentially, as an input, a "Person" object gathers all the task/workTime for a specific date. As an output, I want the "Person" object to gather the date/workTime for a specific task. I need to use XLST 1.0. I've been trying to use grouping with key but get very puzzled. Appreciate your help.

  • Convert json data to javascript array - in multi-dimensional sense

    - by AW-GWTF899
    I have a json array say { "People": { "Person": [ {"FirstName": "John", "LastName": "Smith"} {"FirstName": "Joe", "LastName": "Bloggs"} {"FirstName": "Wendy", "LastName": "Deng"} ] } } And I want to convert this into a javascript array (something like this) var persons = [ ["FirstName", "John", "LastName", "Smith"], ["FirstName", "Joe", "LastName", "Bloggs"], ["FirstName", "Wendy", "LastName": "Deng"] ]; How do I accomplish this? Hope my question makes sense and I realise the javascript array initialization may not be the correct way to put it. Thanks.

  • GridView paging inside an UpdatePanel or PlaceHolder components

    - by John
    Hello, I'm new to ASP.NET. Im developing ASP.NET C# web form which creating GridView components dynamically and filling them using the data received from my webservice. I'm creating these GridView components programmatically in server-side (cs file)- it has to be flexible - 1 GridView and sometimes 10 GridView components. The problem occurs when I'm trying to add pagination - whenever the user clicks the "next" page, the whole page is getting refreshed because of a postBack and I'm loosing all my data and the page returns Blank/Empty. I used PlaceHolder to hold the GridView components, while searching for a solution, I found UpdatePanel as a better alternative - as far as I understand the page can be partially refreshed - which means that only the UpdatePanel has to be refreshed...but it doesn't work. The following code sample is my TEST, the UpdatePanel is the only component initiated in the client side (aspx page), the rest initiated programmatically in CS. how can I solve the issue described above? Why does the whole page is getting refreshed and I'm loosing my data? can you recommend another way? can provide me with any code sample? If I'm not rebuilding the GridView, it doesn't work... Here is my Default.aspx.cs: public partial class TestAjaxForm : System.Web.UI.Page { DataTable table; protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) bindGridView(); } public void bindGridView() { GridView gridView1 = new GridView(); gridView1.AutoGenerateColumns = true; gridView1.PageSize = 2; gridView1.AllowPaging = true; gridView1.PagerSettings.Mode = PagerButtons.Numeric; gridView1.PagerSettings.Position = PagerPosition.Bottom; gridView1.PagerSettings.PageButtonCount = 10; gridView1.PageIndexChanging += new GridViewPageEventHandler(this.GridView1_PageIndexChanging); table = new DataTable(); table.Columns.Add("FirstName"); table.Columns.Add("LastName"); DataRow row = table.NewRow(); row["FirstName"] = "John"; row["LastName"] = "Johnoson"; table.Rows.Add(row); row = table.NewRow(); row["FirstName"] = "Johnny"; row["LastName"] = "Marley"; table.Rows.Add(row); row = table.NewRow(); row["FirstName"] = "Kate"; row["LastName"] = "Li"; table.Rows.Add(row); panel.ContentTemplateContainer.Controls.Add(gridView1); gridView1.DataSource = table; gridView1.DataBind(); } protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e) { GridView gridView1 = (GridView)sender; gridView1.PageIndex = e.NewPageIndex; gridView1.DataSource = table; gridView1.DataBind(); } } Please help me, Thank you.

  • Should I deal with files longer than MAX_PATH?

    - by John
    Just had an interesting case. My software reported back a failure caused by a path being longer than MAX_PATH. The path was just a plain old document in My Documents, e.g.: C:\Documents and Settings\Bill\Some Stupid FOlder Name\A really ridiculously long file thats really very very very..........very long.pdf Total length 269 characters (MAX_PATH==260). The user wasn't using a external hard drive or anything like that. This was a file on an Windows managed drive. So my question is this. Should I care? I'm not saying can I deal with the long paths, I'm asking should I. Yes I'm aware of the "\?\" unicode hack on some Win32 APIs, but it seems this hack is not without risk (as it's changing the behaviour of the way the APIs parse paths) and also isn't supported by all APIs . So anyway, let me just state my position/assertions: First presumably the only way the user was able to break this limit is if the app she used uses the special Unicode hack. It's a PDF file, so maybe the PDF tool she used uses this hack. I tried to reproduce this (by using the unicode hack) and experimented. What I found was that although the file appears in Explorer, I can do nothing with it. I can't open it, I can't choose "Properties" (Windows 7). Other common apps can't open the file (e.g. IE, Firefox, Notepad). Explorer will also not let me create files/dirs which are too long - it just refuses. Ditto for command line tool cmd.exe. So basically, one could look at it this way: a rouge tool has allowed the user to create a file which is not accessible by a lot of Windows (e.g. Explorer). I could take the view that I shouldn't have to deal with this. (As an aside, this isn't an vote of approval for a short max path length: I think 260 chars is a joke, I'm just saying that if Windows shell and some APIs can't handle 260 then why should I?). So, is this a fair view? Should I say "Not my problem"? Thanks! John

  • No output from Linq to XML

    - by Gogster
    Hi all, I have the following code: protected void Page_Load(object sender, EventArgs e) { XElement xml = XElement.Load(Server.MapPath("ArenasMembers.xml")); var query = from p in xml.Descendants("members") select new { Name = p.Element("name").Value, Email = p.Attribute("email").Value }; foreach (var member in query) { Response.Write("Employee: " + member.Name + " " + member.Email + "<br />"); } } Which, using the hover information in Visual Studio, is reading the XNL file in correctly, however the foreach is not outputting any of the records. XML: <?xml version="1.0" encoding="utf-8" ?> <members> <member> <arena>EAA Office</arena> <memberid>1</memberid> <name>Jane Doe</name> <email>[email protected]</email> </member> <member> <arena>EAA Office</arena> <memberid>2</memberid> <name>John Bull</name> <email>[email protected]</email> </member> <member> <arena>O2 Arena</arena> <memberid>3</memberid> <name>John Doe</name> <email>[email protected]</email> </member> <member> <arena>O2 Arena</arena> <memberid>4</memberid> <name>Bernard Cribbins</name> <email>[email protected]</email> </member> <member> <arena>Colourline Arena</arena> <memberid>5</memberid> <name>John Bon Jovi</name> <email>[email protected]</email> </member> <member> <arena>NIA</arena> <memberid>6</memberid> <name>Rhianna</name> <email>[email protected]</email> </member> </members> Can you see what is wrong?

  • Simple way to encode a string according to a password?

    - by RexE
    Does Python have a built-in, simple way of encoding/decoding strings using a password? Something like this: >>> encode('John Doe', password = 'mypass') 'sjkl28cn2sx0' >>> decode('sjkl28cn2sx0', password = 'mypass') 'John Doe' I would like to use these encrypted strings as URL parameters. My goal is obfuscation, not strong security. I realize I could use a database table to store keys and values, but am trying to be minimalist.

  • Minimalist, Tiny Javascript Template System?

    - by Parand
    I'm looking for a minimalist template system for javascript, ala John Resig's Javascript Micro Templating. The smaller the better, and if it's jquery based even better. Recommendations? I tried John's micro-templating but ran into a few issues, wanted to see if there are more baked / better packaged solutions out there. [Update] I tried Resig's Micro Templating again and it's working well for me. Would still like to hear about other alternatives if there are any.

  • Using GET Method to Maintain Variables After Logging In

    - by John
    Hello, I am using a login system. When I navigate to comments/index.php without logging in, some variables get passed along using the GET method just fine. Then, if I log in while I am on this page, these variables disappear. The variables that disappear are $submission, $submissionid, and $url. I thought I could use the GET method to keep them live after logging in by appending ?submission='.$submission.'&submissionid='.$submissionid.'&url='.$url.' to the URL of the login form action as seen below. But the variables still disappeared after I made this addition. The relevant code I am trying to use is below. Any idea what I can do to make it do what I want? Thanks in advance, John In comments/index.php: require_once "header.php"; include "login.php"; include "comments.php"; In login.php: if (!isLoggedIn()) { if (isset($_POST['cmdlogin'])) { if (checkLogin($_POST['username'], $_POST['password'])) { show_userbox(); } else { echo "Incorrect Login information !"; show_loginform(); } } else { show_loginform(); } } else { show_userbox(); } In comments.php: $url = mysql_real_escape_string($_GET['url']); echo '<div class="subcommenttitle"><a href="http://www.'.$url.'">'.$submission.'</a></div>'; $submission = mysql_real_escape_string($_GET['submission']); $submissionid = mysql_real_escape_string($_GET['submissionid']); The login function: function show_loginform($disabled = false) { echo '<form name="login-form" id="login-form" method="post" action="./index.php?submission='.$submission.'&submissionid='.$submissionid.'&url='.$url.'"> <div class="usernameformtext"><label title="Username">Username: </label></div> <div class="usernameformfield"><input tabindex="1" accesskey="u" name="username" type="text" maxlength="30" id="username" /></div> <div class="passwordformtext"><label title="Password">Password: </label></div> <div class="passwordformfield"><input tabindex="2" accesskey="p" name="password" type="password" maxlength="15" id="password" /></div> <div class="registertext"><a href="http://www...com/sandbox/register.php" title="Register">Register</a></div> <div class="lostpasswordtext"><a href="http://www...com/sandbox/lostpassword.php" title="Lost Password">Lost password?</a></div> <p class="loginbutton"><input tabindex="3" accesskey="l" type="submit" name="cmdlogin" value="Login" '; if ($disabled == true) { echo 'disabled="disabled"'; } echo ' /></p></form>'; }
