  • Always get exception when trying to Fill data to DataTable

    - by Sambath
    The code below is just a test to connect to an Oracle database and fill data to a DataTable. After executing the statement da.Fill(dt);, I always get the exception "Exception of type 'System.OutOfMemoryException' was thrown.". Has anyone met this kind of error? My project is running on VS 2005, and my Oracle database version is 11g. My computer is using Windows Vista. If I copy this code to run on Windows XP, it works fine. Thank you. using System.Data; using Oracle.DataAccess.Client; ... string cnString = "data source=net_service_name; user id=username; password=xxx;"; OracleDataAdapter da = new OracleDataAdapter("select 1 from dual", cnString); try { DataTable dt = new DataTable(); da.Fill(dt); // Got error here Console.Write(dt.Rows.Count.ToString()); } catch (Exception e) { Console.Write(e.Message); // Exception of type 'System.OutOfMemoryException' was thrown. } Update I have no idea what happens to my computer. I just reinstall Oracle 11g, and then my code works normally.

  • JQGRID Master detail on different pages

    - by dennisg
    Hello, I need some help on next things. I was trying to do next few things. I have one grid_test.php (that creates jqgrid) and index_grid.php (just to display grid.php). jQGrid in grid.php have custom button named 'Prikazi'. I want the user to select one row from that grid and when press custom button 'Prikazi' to redirect to another page to show subgrid (and to pass parameter which is the id of the selected row). Subgrid is in the file detail_test.php and also I have file called index_detail.php (for displaying the file detail_test.php with jqgrid). These php files communicate by passing parameter id_reda (or id) that is id of the selected row in grid_test.php. I have tried many ways to achieve that but I wasn't able. Subgrid php file (detail_test.php) receives that parameter but when I add that to sql statement in subgrid file it shows next error: Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'LIMIT 0, 0' at line 16' in C:\Zend\Apache2\htdocs\jqSuitePHP3811SourceRadna\php\jqGridPdo.php:62 I really don't know what am I doing wrong. Maybe the passing of parameter is wrong and maybe subgrid can't create colModel properly. Or it has something to do with sql statements. Actually my work was based on one of your examples masterdetail, but I wanted to have master grid on one page and when user clicks custom button, goes to another page with detail grid. You can see my example on next page: http://pljevlja.org/grid/index_test.php. And all my php files are here: -http://pljevlja.org/grid/TXT.zip<- Thanks in advance,

  • Blocking on DBCP connection pool (open and close connnection). Is database connection pooling in OpenEJB pluggable?

    - by topchef
    We use OpenEJB on Tomcat (used to run on JBoss, Weblogic, etc.). While running load tests we experience significant performance problems with handling JMS messages (queues). Problem was localized to blocking on database connection pool getting or releasing connection to the pool. Blocking prevented concurrent MDB instances (threads) from running hence performance suffered 10-fold and worse. The same code used to run on application servers (with their respective connection pool implementations) with no blocking at all. Example of thread blocked: Name: JMS Resource Adapter-worker-23 State: BLOCKED on org.apache.commons.pool.impl.GenericObjectPool@1ea6b4a owned by: JMS Resource Adapter-worker-19 Total blocked: 18,426 Total waited: 0 Stack trace: org.apache.commons.pool.impl.GenericObjectPool.returnObject(GenericObjectPool.java:916) org.apache.commons.dbcp.PoolableConnection.close(PoolableConnection.java:91) - locked org.apache.commons.dbcp.PoolableConnection@1bcba8 org.apache.commons.dbcp.managed.ManagedConnection.close(ManagedConnection.java:147) com.xxxxx.persistence.DbHelper.closeConnection(DbHelper.java:290) .... Couple of questions. I am almost certain that some transactional attributes and properties contribute to this blocking, but MDBs are defined as non-transactional (we use both annotations and ejb-jar.xml). Some EJBs do use container-managed transactions though (and we can observe blocking there as well). Are there any DBCP configurations that may fix blocking? Is DBCP connection pool implementation replaceable in OpenEJB? How easy (difficult) to replace it with another library? Just in case this is how we define data source in OpenEJB (openejb.xml): <Resource id="MyDataSource" type="DataSource"> JdbcDriver oracle.jdbc.driver.OracleDriver JdbcUrl ${oracle.jdbc} UserName ${oracle.user} Password ${oracle.password} JtaManaged true InitialSize 5 MaxActive 30 ValidationQuery SELECT 1 FROM DUAL TestOnBorrow true </Resource>

  • sql server 2005 stored procedure unexpected behaviour

    - by user283405
    i have written a simple stored procedure (run as job) that checks user subscribe keyword alerts. when article posted the stored procedure sends email to those users if the subscribed keyword matched with article title. One section of my stored procedure is: OPEN @getInputBuffer FETCH NEXT FROM @getInputBuffer INTO @String WHILE @@FETCH_STATUS = 0 BEGIN --PRINT @String INSERT INTO #Temp(ArticleID,UserID) SELECT A.ID,@UserID FROM CONTAINSTABLE(Question,(Text),@String) QQ JOIN Article A WITH (NOLOCK) ON A.ID = QQ.[Key] WHERE A.ID > @ArticleID FETCH NEXT FROM @getInputBuffer INTO @String END CLOSE @getInputBuffer DEALLOCATE @getInputBuffer This job run every 5 minute and it checks last 50 articles. It was working fine for last 3 months but a week before it behaved unexpectedly. The problem is that it sends irrelevant results. The @String contains user alert keyword and it matches to the latest articles using Full text search. The normal execution time is 3 minutes but its execution time is 3 days (in problem). Now the current status is its working fine but we are unable to find any reason why it sent irrelevant results. Note: I am already removing noise words from user alert keyword. I am using SQL Server 2005 Enterprise Edition.

  • Weird Issues with WPMU I Can't Figure Out

    - by HollerTrain
    I know I should post this on the WPMU forum, but no one writes me back and I'm just trying to find a larger audience hoping you have run into this issue as well. I have built a WPMU site for a client, and I am able to upload media into the Media Library and within a Post or Page perfectly. I thought my job was finished, yet the client can't upload any media at all. I'm located in Kentucky, they are located in New England (if that even matters). I had the client record their process of uploading as I thought they were simply not following my instructions for uploading, yet they are doing everything correctly. When uploading a file it goes through the process of allowing them to select a file and it says it uploads it, yet when it is finished uploading nothing is in the Media Library or in the Post. Video of the client trying to upload in Media Manager (http://www.screencast.com/users/CatherineWeber/folders/Jing/media/945d33fa-a752-45fd-9bc1-f76fc5a1814a) Video of the client trying to upload within a Post (http://www.screencast.com/users/CatherineWeber/folders/Jing/media/b5c60e25-f0b5-40c0-a820-c2fc9eb00906) Asking the client to disable Flash Uploader didn't work :( Yet, I can login to the WPMU site, access their blog's backend and can easily upload a ton of files. I am so lost at to what the issue is here. I am running version 2.8.4a, and will try to upgrade to latest release hoping this will fix things.

  • #Error showing up in multiple LEFT JOIN statement Access query when value should be NULL

    - by lar
    I'm trying to return an ID's last 4 years of data, if existing. The table (call it A_TABLE) looks like this: ID, Year, Val The idea behind the query is this: for each ID/Year in the table, LEFT JOIN with Year-1, Year-2, and Year-3 (to get 4 years of data) and then return Val for each year. Here's the SQL: SELECT a.ID, a.year AS [Year], a.Val AS VAL, a1.year AS [Year-1], a1.Val AS [VAL-1], a2.year AS [Year-2], a2.Val AS [VAL-2], a3.year AS [Year-3], a3.Val AS [VAL-3] FROM ( ([A_TABLE] AS a LEFT JOIN [A_TABLE] AS a1 ON (a.ID = a1.ID) AND (a.year = a1.year+1)) LEFT JOIN [A_TABLE] AS a2 ON (a.ID = a2.ID) AND (a.year = a2.year+2)) LEFT JOIN [A_TABLE] AS a3 ON (a.ID = a3.ID) AND (a.year = a3.year+3) The problem is that, for past years where there is no data (eg, Year-1), I see "#Error" in the appropriate VAL column (eg, [VAL-1]). The weird thing is, I see the expected "null" in the Year column (eg, [YEAR-1]). Some sample data: ID YEAR VAL Dave 2004 1 Dave 2006 2 Dave 2007 3 Dave 2008 5 Dave 2009 0 outputs like this: ID YEAR VAL YEAR-1 VAL-1 YEAR-2 VAL-2 YEAR-3 VAL-3 Dave 2004 1 #Error #Error #Error Dave 2006 2 #Error 2004 1 #Error Dave 2007 3 2006 2 #Error 2004 1 Dave 2008 5 2007 3 2006 2 #Error Dave 2009 0 2008 5 2007 3 2006 2 Does that make sense? Why am I getting the appropriate NULL val for the non-existent YEARs, but an #Error for the non-existent VALs? (This is Access 2000. Conditional statements like "IIf(a1.val is null, -999, a1.val)" do not seem to do anything.) EDIT: It turns out that the errors are somehow caused by the fact that A_TABLE is actually a query. When I put all the data into an actual table and run the same query, everything shows up as it should. Thanks for the help, everyone.

  • Creating a DataTable by filtering another DataTable

    - by Jeff Dege
    I'm working on a system that currently has a fairly complicated function that returns a DataTable, which it then binds to a GUI control on a ASP.NET WebForm. My problem is that I need to filter the data returned - some of the data that is being returned should not be displayed to the user. I'm aware of DataTable.select(), but that's not really what I need. First, it returns an array of DataRows, and I need a DataTable, so I can databind it to the GUI control. But more importantly, the filtering I need to do isn't something that can be easily put into a simple expression. I have an array of the elements which I do not want displayed, and I need to compare each element from the DataTable against that array. What I could do, of course, is to create a new DataTable, reading everything out of the original, adding to the new what is appropriate, then databinding the new to the GUI control. But that just seems wrong, somehow. In this case, the number of elements in the original DataTable aren't likely to be enough that copying them all in memory is going to cause too much trouble, but I'm wondering if there is another way. Does the .NET DataTable have functionality that would allow me to filter via a callback function?

  • How to set different width for INPUT and DIV elements with Scriptaculous Ajax.Autocompleter?

    - by Grzegorz Gierlik
    Hello, I am working on autocompleter box based on Scriptaculous Ajax.Autocompleter. Here how my HTML/JS code looks like: <input type="text" maxlength="255" class="input iSearchInput" name="isearch_value" id="isearch" value="<wl@txt>Search</wl@txt>" onfocus="this.select()"> <br> <div id='isearch_choices' class='iSearchChoices'></div> <script> function iSearchGetSelectedId(text, li) { console.log([text, li.innerHTML].join("\n")); document.location.href = li.getAttribute("url"); } document.observe('dom:loaded', function() { new Ajax.Autocompleter("isearch", "isearch_choices", "/url", { paramName: "phrase", minChars: 1, afterUpdateElement : iSearchGetSelectedId }); $("isearch_choices").setStyle({width: "320px"}); }); </script> and CSS classes: input.iSearchInput { width: 155px; height: 26px; margin-top: 7px; line-height: 20px; } div.iSearchChoices { position:absolute; background-color:white; border:1px solid #888; margin:0; padding:0; width: 320px; } It works in general, but I need to have list of choices wider then input box. My first try was to set various width with CSS classes (like above), but it didn't work -- list of choices became as wide as input box. According to Firebug width defined by my CSS class was overwritten by width set by element.style CSS class, which seems to be defined by Ajax.Autocompleter. My second try was to set width for list of choices after creating Ajax.Autocompleter $("isearch_choices").setStyle({width: "320px"}); but it didn't work too :(. No more ideas :(. How to set different width for list of choices for Scriptaculous Ajax.Autocompleter?

  • 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.

  • Drop Down Box and other stuff in ASP.NET with VB.NET (VS 2008)

    - by typoknig
    Hi all, I am trying to polish up a program a program that I have converted from a Windows Form in to an ASP.NET Web Application. I have several questions: 1.) I have a drop down box where users can select their variables, but users can also enter their variables manually into various text fields. What I want is for the drop down box to show a string like "Choose Variables" when ever the user enters their variables manually. I want this to happen without having to reload the page. 2.) In the Windows Form version of this application I had a RichTextBox that populated with data (line by line) after a calculation was made. I used "AppendText" in my Windows Form, but that is not available in ASP.NET, and neither is the RichTextBox. I am open to suggestions here, I tried to use just a text box but that isn't working right. 3.) In my Windows Form application I was using "KeyPress" events to prevent incorrect characters from being entered into the text fields. My code for these events looked similar to this: Private Sub TextBox_KeyPress(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles TextBox.KeyPress If (e.KeyChar < "0" OrElse e.KeyChar > "9") AndAlso e.KeyChar <> ControlChars.Back AndAlso e.KeyChar <> "." Then e.Handled = True End If End Sub How can I make this work again... also without reloading the page. 4.) This is not a major issue, but I would like all of the text to be selected when the cursor enters a field. In my Windows Form application I used "SelectAll", but again, that is not available in ASP.NET Thanks in advanced.

  • Jquery UI Datepicker not displaying

  • jQuery capture all changes to named inpt on a form

    - by Brian M. Hunt
    I'm trying to determine when any of a set of named input/select/radio/checked/hidden fields in a form change. In particular, I'd like to capture when any changes are made to fields matching jQuery's selector $("form :input"), and where that input is has a name attribute. However, the form isn't static i.e. some of the fields are dynamically added later. My initial thought is to keep track of when new named elements matching :input are added, and then add an event handler, like this: function on_change() { alert("The form element with name " + $(this).attr("name") + " has changed"); } function reg_new_e_handler(input_element) { input_element.change(on_change); } However, I'm quite hopeful I can avoid this with some jQuery magic. In particular, is there a way to register an event handler in jQuery that would handle input elements that match the following: $("form :input").filter( function () { $(this).attr("name") } ).change(on_change); However, have this event set update whenever new input elements are added. I've thought that it may be possible to capture keyup event on the form node with $("form").keyup(on_change), but I'm not so sure how one could capture change events. I'd also like this to capture keyup events. Thank you for reading. Brian

  • Submit WordPress form password programmatically

    - by songdogtech
    How can I let a user access a WordPress protected page with a URL that will submit the password in the form below? I want to be able to let a user get to a password protected WordPress page without needing to type the password, so when they go to the page, the password is submitted by a POST URL on page load. This not intended to be secure in any respect; I'll need to hardcode the password in the URL and the PHP. It's just for simplicity for the user, and once they're in, the cookie will let them in for 10 more days. I will select the particular user with separate PHP function that determines their IP or WordPress login status. I used Wireshark to find the POST string: post_password=mypassword&Submit=Submit but using this URL mydomain.com/wp-pass.php?post_password=mypassword&Submit=Submit gives me a blank page. This is the form: <form action="http://mydomain.com/wp-pass.php" method="post"> Password: <input name="post_password" type="password" size="20" /> <input type="submit" name="Submit" value="Submit" /></form> This is wp-pass.php: <?php require( dirname(__FILE__) . '/wp-load.php'); if ( get_magic_quotes_gpc() ) $_POST['post_password'] = stripslashes($_POST['post_password']); setcookie('wp-postpass_' . COOKIEHASH, $_POST['post_password'], time() + 864000, COOKIEPATH); wp_safe_redirect(wp_get_referer()); ?> What am I doing wrong? Or is there a better way to let a user into a password protected page automatically?

  • ASP.NET OleDbConnection Problem

    - by Matt
    I'm working on an ASP.NET website where I am using an asp:repeater with paging done through a VB.NET code-behind file. I'm having trouble with the database connection though. As far as I can tell, the paging is working, but I can't get the data to be certain. The database is a Microsoft Access database. The function that should be accessing the database is: Dim pagedData As New PagedDataSource Sub Page_Load(ByVal obj As Object, ByVal e As EventArgs) doPaging() End Sub Function getTheData() As DataTable Dim DS As New DataSet() Dim strConnect As New OleDbConnection("Provider = Microsoft.Jet.OLEDB.4.0;Data Source=App_Data/ArtDatabase.mdb") Dim objOleDBAdapter As New OleDbDataAdapter("SELECT ArtID, FileLocation, Title, UserName, ArtDate FROM Art ORDER BY Art.ArtDate DESC", strConnect) objOleDBAdapter.Fill(DS, "Art") Return DS.Tables("Art").Copy End Function Sub doPaging() pagedData.DataSource = getTheData().DefaultView pagedData.AllowPaging = True pagedData.PageSize = 2 Try pagedData.CurrentPageIndex = Int32.Parse(Request.QueryString("Page")).ToString() Catch ex As Exception pagedData.CurrentPageIndex = 0 End Try btnPrev.Visible = (Not pagedData.IsFirstPage) btnNext.Visible = (Not pagedData.IsLastPage) pageNumber.Text = (pagedData.CurrentPageIndex + 1) & " of " & pagedData.PageCount ArtRepeater.DataSource = pagedData ArtRepeater.DataBind() End Sub The ASP.NET is: <asp:Repeater ID="ArtRepeater" runat="server"> <HeaderTemplate> <h2>Items in Selected Category:</h2> </HeaderTemplate> <ItemTemplate> <li> <asp:HyperLink runat="server" ID="HyperLink" NavigateUrl='<%# Eval("ArtID", "ArtPiece.aspx?ArtID={0}") %>'> <img src="<%# Eval("FileLocation") %>" alt="<%# DataBinder.Eval(Container.DataItem, "Title") %>t"/> <br /> <%# DataBinder.Eval(Container.DataItem, "Title") %> </asp:HyperLink> </li> </ItemTemplate> </asp:Repeater>

  • Delphi Mock Wizard

    - by Todd
    Let me preface this by saying I'm fairly new to Unit Testing, Mocks, Stubs, Etc... I've installed Delphi-Mock-Wizard. When I select a unit and "Generate Mock", a new unit is created but it's very basic and not anything what I understand Mocks to be. unit Unit1; (** WARNING - AUTO-GENERATED MOCK! Change this unit if you want to, but be aware that any changes you make will be lost if you regenerate the mock object (for instance, if the interface changes). My advice is to create a descendent class of your auto-generated mock - in a different unit - and override things there. That way you get to keep them. Also, the auto-generate code is not yet smart enough to generate stubs for inherited interfaces. In that case, change your mock declaration to inherit from a mock implementation that implements the missing interface. This, unfortunately, is a violation of the directive above. I'm working on it. You may also need to manually change the unit name, above. Another thing I am working on. **) interface uses PascalMock, TestInterfaces; type IThingy = interface; implementation end. Looking at the source there seems to be quite a bit commented out. I'm wondering, has anyone gotten this to work? My IDE is D2010. Thanks.

    Hello all the general idea is to create a galaxy-like map. I run into problems when I try to display a generated image. I used Python Image library to create the image and store it in the datastore. when i try to load the image i get no error on the log console and no image on the browser. when i copy/paste the image link (including datastore key) i get a black screen and the following message: The image “view-source:/localhost:8080/img?img_id=ag5kZXZ-c3BhY2VzaW0xMnINCxIHTWFpbk1hcBgeDA” cannot be displayed because it contains errors. the firefox error console: Error: Image corrupt or truncated: /localhost:8080/img?img_id=ag5kZXZ-c3BhY2VzaW0xMnINCxIHTWFpbk1hcBgeDA import cgi import datetime import urllib import webapp2 import jinja2 import os import math import sys from google.appengine.ext import db from google.appengine.api import users from PIL import Image #SNIP #class to define the map entity class MainMap(db.Model): defaultmap = db.BlobProperty(default=None) #SNIP class Generator(webapp2.RequestHandler): def post(self): #SNIP test = Image.new("RGBA",(100, 100)) dMap=MainMap() dMap.defaultmap = db.Blob(str(test)) dMap.put() #SNIP result = db.GqlQuery("SELECT * FROM MainMap LIMIT 1").fetch(1) if result: print"item found<br>" #debug info if result[0].defaultmap: print"defaultmap found<br>" #debug info string = "<div><img src='/img?img_id=" + str(result[0].key()) + "' width='100' height='100'></img>" print string else: print"nothing found<br>" else: self.redirect('/?=error') self.redirect('/') class Image_load(webapp2.RequestHandler): def get(self): self.response.out.write("started Image load") defaultmap = db.get(self.request.get("img_id")) if defaultmap.defaultmap: try: self.response.headers['Content-Type'] = "image/png" self.response.out.write(defaultmap.defaultmap) self.response.out.write("Image found") except: print "Unexpected error:", sys.exc_info()[0] else: self.response.out.write("No image") #SNIP app = webapp2.WSGIApplication([('/', MainPage), ('/generator', Generator), ('/img', Image_load)], debug=True) the browser shows the "item found" and "defaultmap found" strings and a broken imagelink the exception handling does not catch any errors Thanks for your help Regards Bert

  • Errors In Programmatically Running ANT Build In Eclipse

    - by Sujay
    I am trying to run an ANT script through a small Java program and I keep on encountering the following error: build: Exception in thread "main" build.xml:7: Problem: failed to create task or type eclipse.refreshLocal Cause: The name is undefined. Action: Check the spelling. Action: Check that any custom tasks/types have been declared. Action: Check that any <presetdef>/<macrodef> declarations have taken place. at org.apache.tools.ant.UnknownElement.getNotFoundException(UnknownElement.java:487) at org.apache.tools.ant.UnknownElement.makeObject(UnknownElement.java:419) at org.apache.tools.ant.UnknownElement.maybeConfigure(UnknownElement.java:163) I used to get this problem when I used to execute the build file manually. All I had to do to make Eclipse run this build was to go to Run External Tools External Tools Configuration JRE and select "Run in the same JRE as the workspace" and then attempt to execute. But I have no idea how to achieve the same effect through my code. Any suggestion would really be appreciated. Note that this has reference to a previous question that I asked over here

  • raw_id_fields for modelforms

    - by nbv4
    I have a modelform which has one field that is a ForeignKey value to a model which as 40,000 rows. The default modelform tries to create a select box with 40,000 options, which, to say the least is not ideal. Even more so when this modelform is used in a formset factory! In the admin, this is easiely avoidable by using "raw_id_fields", but there doesn't seem to be a modelform equivalent. How can I do this? Here is my modelform: class OpBaseForm(ModelForm): base = forms.CharField() class Meta: model = OpBase exclude = ['operation', 'routes'] extra = 0 raw_id_fields = ('base', ) #does nothing The first bolded line works by not creating the huge unwieldy selectbox, but when I try to save a fieldset of this form, I get the error: "OpBase.base" must be a "Base" instance. In order for the modelform to be saved, 'base' needs to be a Base instance. Apparently, a string representation of a Base primary key isn't enough (at least not automatically). I need some kind of mechanism to change the string that is given my the form, to a Base instance. And this mechanism has to work in a formset. Any ideas? If only raw_id_fields would work, this would be easy as cake. But as far as I can tell, it only is available in the admin.

  • Assembly reference from ASP.NET App_Code directory

    - by Gerald Schneider
    I have trouble getting a custom ObjectDataSource for an asp:ListView control to work. I have the class for the DataSource in the App_Code directory of the web application (as required by the asp:ListView control). using System; using System.Collections.Generic; using System.ComponentModel; using System.Configuration; using System.Data; using System.Data.Common; using System.Web; using System.DirectoryServices; [DataObject] public class UsersDAL { [DataObjectMethod(DataObjectMethodType.Select)] public List<User> LoadAll(int startIndex, int maxRows, string sortedBy) { List<User> users = new List<User>(); DirectoryEntry entry; return users; } } As soon as I add using System.DirectoryServices; the page crashes with this message: Compiler Error Message: CS0234: The type or namespace name 'DirectoryServices' does not exist in the namespace 'System' (are you missing an assembly reference?) Without the usage of System.DirectoryServices the page loads without problems. The reference is there, it is working in classes outside the App_Code directory.

  • Slow MySQL Query not using filesort

    - by Canadaka
    I have a query on my homepage that is getting slower and slower as my database table grows larger. tablename = tweets_cache rows = 572,327 this is the query I'm currently using that is slow, over 5 seconds. SELECT * FROM tweets_cache t WHERE t.province='' AND t.mp='0' ORDER BY t.published DESC LIMIT 50; If I take out either the WHERE or the ORDER BY, then the query is super fast 0.016 seconds. I have the following indexes on the tweets_cache table. PRIMARY published mp category province author So i'm not sure why its not using the indexes since mp, provice and published all have indexes? Doing a profile of the query shows that its not using an index to sort the query and is using filesort which is really slow. possible_keys = mp,province Extra = Using where; Using filesort I tried adding a new multie-colum index with "profiles & mp". The explain shows that this new index listed under "possible_keys" and "key", but the query time is unchanged, still over 5 seconds. Here is a screenshot of the profiler info on the query. http://i355.photobucket.com/albums/r469/canadaka_bucket/slow_query_profile.png Something weird, I made a dump of my database to test on my local desktop so i don't screw up the live site. The same query on my local runs super fast, milliseconds. So I copied all the same mysql startup variables from the server to my local to make sure there wasn't some setting that might be causing this. But even after that the local query runs super fast, but the one on the live server is over 5 seconds. My database server is only using around 800MB of the 4GB it has available. here are the related my.ini settings i'm using default-storage-engine = MYISAM max_connections = 800 skip-locking key_buffer = 512M max_allowed_packet = 1M table_cache = 512 sort_buffer_size = 4M read_buffer_size = 4M read_rnd_buffer_size = 16M myisam_sort_buffer_size = 64M thread_cache_size = 8 query_cache_size = 128M # Try number of CPU's*2 for thread_concurrency thread_concurrency = 8 # Disable Federated by default skip-federated key_buffer = 512M sort_buffer_size = 256M read_buffer = 2M write_buffer = 2M key_buffer = 512M sort_buffer_size = 256M read_buffer = 2M write_buffer = 2M

  • Implementing parts of rfc4226 (HOTP) in mysql

    - by Moose Morals
    Like the title says, I'm trying to implement the programmatic parts of RFC4226 "HOTP: An HMAC-Based One-Time Password Algorithm" in SQL. I think I've got a version that works (in that for a small test sample, it produces the same result as the Java version in the code), but it contains a nested pair of hex(unhex()) calls, which I feel can be done better. I am constrained by a) needing to do this algorithm, and b) needing to do it in mysql, otherwise I'm happy to look at other ways of doing this. What I've got so far: -- From the inside out... -- Concatinate the users secret, and the number of time its been used -- find the SHA1 hash of that string -- Turn a 40 byte hex encoding into a 20 byte binary string -- keep the first 4 bytes -- turn those back into a hex represnetation -- convert that into an integer -- Throw away the most-significant bit (solves signed/unsigned problems) -- Truncate to 6 digits -- store into otp -- from the otpsecrets table select (conv(hex(substr(unhex(sha1(concat(secret, uses))), 1, 4)), 16, 10) & 0x7fffffff) % 1000000 into otp from otpsecrets; Is there a better (more efficient) way of doing this?

  • flex actionscript not uploading file to PHP page HELP!

    - by Rees
    hello, please help! I am using actionscript 3 with flex sdk 3.5 and PHP to allow a user to upload a file -that is my goal. However, when I check my server directory for the file... NOTHING is there! For some reason SOMETHING is going wrong, even though the actionscript alerts a successful upload (and I have even tried all the event listeners for uploading errors and none are triggered). I have also tested the PHP script and it uploads SUCCESSFULLY when receiving a file from another PHP page (so i'm left to believe there is nothing wrong with my PHP). However, actionscript is NOT giving me any errors when I upload -in fact it gives me a successful event...and I know the my flex application is actually trying to send the data because when I attempt to upload a large file, it takes significantly more time to alert a "successful" event than when I upload a small file. I feel I have debugged every aspect of this code and am now spent. pleaseeee, anyone, can you tell me whats going wrong?? or at least how I can find out whats happening? -I'm using flash bugger and I'm still getting zero errors. private var fileRef:FileReference = new FileReference(); private var flyerrequest:URLRequest = new URLRequest("http://mysite.com/sub/upload_file.php"); private function uploadFile():void{ fileRef.browse(); fileRef.addEventListener(Event.SELECT, selectHandler); fileRef.addEventListener(Event.COMPLETE, completeHandler); } private function selectHandler(event:Event):void{ fileRef.upload(flyerrequest); } private function completeHandler(event:Event):void{ Alert.show("uploaded"); }
