  • uploadify scriptData problem

    - by elpaso66
    Hi, I'm having problems with scriptData on uploadify, I'm pretty sure the config syntax is fine but whatever I do, scriptData is not passed to the upload script. I tested in both FF and Chrome with flash v. Shockwave Flash 9.0 r31 This is the config: $(document).ready(function() { $('#id_file').uploadify({ 'uploader' : '/media/filebrowser/uploadify/uploadify.swf', 'script' : '/admin/filebrowser/upload_file/', 'scriptData' : {'session_key': 'e1b552afde044bdd188ad51af40cfa8e'}, 'checkScript' : '/admin/filebrowser/check_file/', 'cancelImg' : '/media/filebrowser/uploadify/cancel.png', 'auto' : false, 'folder' : '', 'multi' : true, 'fileDesc' : '*.html;*.py;*.js;*.css;*.jpg;*.jpeg;*.gif;*.png;*.tif;*.tiff;*.mp3;*.mp4;*.wav;*.aiff;*.midi;*.m4p;*.mov;*.wmv;*.mpeg;*.mpg;*.avi;*.rm;*.pdf;*.doc;*.rtf;*.txt;*.xls;*.csv;', 'fileExt' : '*.html;*.py;*.js;*.css;*.jpg;*.jpeg;*.gif;*.png;*.tif;*.tiff;*.mp3;*.mp4;*.wav;*.aiff;*.midi;*.m4p;*.mov;*.wmv;*.mpeg;*.mpg;*.avi;*.rm;*.pdf;*.doc;*.rtf;*.txt;*.xls;*.csv;', 'sizeLimit' : 10485760, 'scriptAccess' : 'sameDomain', 'queueSizeLimit' : 50, 'simUploadLimit' : 1, 'width' : 300, 'height' : 30, 'hideButton' : false, 'wmode' : 'transparent', translations : { browseButton: 'BROWSE', error: 'An Error occured', completed: 'Completed', replaceFile: 'Do you want to replace the file', unitKb: 'KB', unitMb: 'MB' } }); $('input:submit').click(function(){ $('#id_file').uploadifyUpload(); return false; }); }); I checked that other values (file name) are passed correctly but session_key is not. This is the decorator code from django-filebrowser, you can see it checks for request.POST.get('session_key'), the problem is that request.POST is empty. def flash_login_required(function): """ Decorator to recognize a user by its session. Used for Flash-Uploading. """ def decorator(request, *args, **kwargs): try: engine = __import__(settings.SESSION_ENGINE, {}, {}, ['']) except: import django.contrib.sessions.backends.db engine = django.contrib.sessions.backends.db print request.POST session_data = engine.SessionStore(request.POST.get('session_key')) user_id = session_data['_auth_user_id'] # will return 404 if the session ID does not resolve to a valid user request.user = get_object_or_404(User, pk=user_id) return function(request, *args, **kwargs) return decorator

  • ASP.NET how to use __doPostBack from Custom JavaScript with Master/Content Pages

    - by harrije
    In a simple aspx page I can have a custom JavaScript function postback as described in http://www.xefteri.com/articles/show.cfm?id=18 The simple page uses a linkbutton: <asp:LinkButton id="CreateFile" runat="server" onclick="CreateFile_Click" /> with code behind that has the VB subroutine: Sub CreateFile_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) and a Javascript custom function that does: __doPostBack('CreateFile',''); When I move the code to a content page with a corresponding master page the simple example no longer works. I'm aware that server control IDs are changed in the generated HTML when a master page is involved, and I'm using the correct IDs in the Javascript. As an example, for the LinkButton ID I use '<%=CreateFile.ClientID%' for the Javascript in the generated HTML. Never the less, I still can't figure out how to get postbacks from the Javascript when master pages are involved. More accurately, with a master page in the mix the code won't even compile but results in: 'CreateFile_Click' is not a member of 'ASP.testmaster_aspx' If I remove onclick="CreateFile_Click" from the LinkButton markup it compiles but does not work. Similary if onclick is removed from the simpler version without a master page it does not work either, as expected. Any input on how to get postback from a custom Javascript function when using master pages would be much appreciated.

  • String formatting in cocoa

    - by lostInTransit
    Hi I am trying to send some text in an email from my cocoa app (by using Mail.app). Initially I tried using HTML to send properly formatted text. But the mailto: URL does not support html tags (even after setting headers) So I decided to use formatted string (left-aligning of string) This is what I have in my mailto: link's body argument NSMutableString *emailBody = [NSMutableString stringWithFormat:@"|%-35s", [@"Name" UTF8String]]; [emailBody appendFormat:@"|%-18s", [@"Number" UTF8String]]; [emailBody appendString:@"|Notes\n"]; [emailBody appendString:@"----------------------------------------------------------------------------------------------------"]; for(int i = 0; i < [items count]; i++){ NSDictionary *props = [items objectAtIndex:i]; NSMutableString *emailData = [NSMutableString stringWithFormat:@"|%-35s", [[props valueForKey:@"name"] UTF8String]]; [emailData appendFormat:@"|$ %-16s", [[props valueForKey:@"number"] UTF8String]]; [emailData appendString:[props valueForKey:@"notes"]]; [emailBody appendString:@"\n"]; [emailBody appendString:emailData]; } This does give me padded text but they all don't necessarily take up the same space (for instance if there is an O in the text, it takes up more space than others and ruins the formatting) Is there another sure-shot way to format text using just NSString? Thanks

  • Selecting text in mobile Safari on iPhone

    - by Goldy
    I'm trying to make it easy for an iphone user to copy some text to the clipboard in mobile safari. As in the usual "touch-hold-copy". There is a specific bit of text I want to a user to copy. I have full choice of the html markup in which to wrap the text. How can I make it easy, rather than abitrary? For instance: Is there a way to "select all" the text upon touch-down using javascript? Then a user could just continue to touch-hold and then choose copy? Is there a way to bring up the "select all" option? Like you can when typing in a text box? After which they can choose copy? If there's no javascript solution, how can I arrange the html to help Safari select the right bit of text easily? As opposed to just a word, or a wrapping div? I've tried onFocus="this.select()" for various elements, none seem to work. Also tried onClick. Those who have tried to port a site that uses ZeroClipboard to the iPhone might have some ideas. Cheers

  • jQuery "Microsoft JScript runtime error: Object expected"

    - by Oskar Kjellin
    I have the below code that does not seem to work at all :( I keep getting: Microsoft JScript runtime error: Object expected The error seems to occur when the timeout is done. So if I raise the timeout with 10 seconds the error holds for another 10 seconds. I want to be able to update the number of friends online async. The number is shown with the following html: <a href="" id="showChat" >Friends online <strong id="friendsOnline">(?)</strong></a> The friends part is set at the first run, but when the timeout calls back it does not fire again. Also, I cannot see on which line the error occurs because if I want to break on the error it just shows "no source code" etc. The code below is the code I'm using. Thanks! <script src="http://ajax.microsoft.com/ajax/jquery/jquery-1.3.2.js" type="text/javascript"></script> <script src='/Scripts/MicrosoftAjax.js' type="text/javascript"></script> <script src='/Scripts/MicrosoftMvcAjax.js' type="text/javascript"></script> <script src='/Scripts/jquery.autocomplete.js' type="text/javascript"></script> <script type="text/javascript"> $(document).ready(function() { UpdateFriendsOnline(); function UpdateFriendsOnline() { window.setTimeout("UpdateFriendsOnline()", 1000); $.get("/Account/GetFriendsOnline", function(data) { $("#friendsOnline").html("(" + data + ")"); }); } }); </script>

  • Calling a MVC2 partial view using jquery returns empty string problem

    - by Jason
    I have an issue where I have a partial view that returns some HTML to be displayed. Its called when something is clicked on the page using jquery. The problem is that no matter how I call it, i get back an empty string even though it reports success. This is happening to me using Chrome, going against my local machine. My controller looks like this: public ActionResult MyPartialView() { return PartialView(model); } I have tried jquery using .get(), .post() and .load() and all have the same results. Here is an example using .post(): $.post(url, function (data) { alert(data); }); The result always comes back as an empty string. I can navigate to the partial view in the browser manually and i get back the desired HTML. The URL I am using to call it I resolved fully so it looks like "http://localhost/controller/mypartialview" rather than using the relative path of "/controller/mypartialview" which I thought was the original problem. Any idea what may cause this?

  • How to build android cts? And how to add and run your test case?

    - by Leox
    From 2.0 the cts is freely downloadable from android's repository. But there is no documents about it. Does anyone can tell me: how to build cts? Is there a standard procedure? How to run cts? How to add customized test case? Here, share my experience. After repo sync all source, you can't directly run "make" to build all source. You will get some errors. Now, I'am trying to first build android source without cts, and then build cts alone. Also, here are some reference for run cts: http://i-miss-erin.blogspot.com/2010/05/how-to-add-test-plan-package-to-android.html www.mentby.com/chenny/how-does-cts-work-where-can-i-get-the-test-streams.html www.jxva.com/?act=blog!article&articleId=157 1st time Update @ 5-13 18:39 +8:00 I do the following steps: 1.build android source without cts (move cts out of the $SDK_ROOT). 2.build cts (move cts back). both jdk1.5 and 1.6 have the following errors: 1.The 1st time "make cts" report: "Caused by: java.io.FileNotFoundException: ...(Too many open files)" 2.The 2nd time "make cts" report: "acp: file 'out/host/linux-x86/obj/EXECUTABLES/vm-tests_intermediates/tests/data' does not exist" 3.The 3rd time "make cts" report: "/bin/bash: line 0: cd: out/host/linux-x86/obj/EXECUTABLES/vm-tests_intermediates/hostjunit_files/classes: No such file or directory" 4.The last time "make cts" report: "zip error: Nothing to do!

  • cannot load JSTL taglib within embedded Jetty server

  • .NET C#: WebBrowser control Navigate() does not load targeted URL

    - by Dave
    Hey guys, I'm trying to programmatically load a web page via the WebBrowser control with the intent of testing the page & it's JavaScript functions. Basically, I want to compare the HTML & JavaScript run through this control against a known output to ascertain whether there is a problem. However, I'm having trouble simply creating and navigating the WebBrowser control. The code below is intended to load the HtmlDocument into the WebBrowser.Document property: WebBrowser wb = new WebBrowser(); wb.AllowNavigation = true; wb.Navigate("http://www.google.com/"); When examining the web browser's state via Intellisense after Navigate() runs, the WebBrowser.ReadyState is 'Uninitialized', WebBrowser.Document = null, and it overall appears completely unaffected by my call. On a contextual note, I'm running this control outside of a Windows form object: I do not need to load a window or actually look at the page. Requirements dictate the need to simply execute the page's JavaScript and examine the resultant HTML. Any suggestions are greatly appreciated, thanks!

  • InnerHTML IE 8 doesn't work properly? Resetting form.

    - by Craig Whitley
    Yeah this works in FF and Chrome, but for some reason wont work in IE 8. I'm using a radio button to clear a section of a form.. that section is a select box, but I don't want to leave the area empty - instead I want to reset it to what it was when the page loaded. At the moment IE8 is just leaving me with an empty small select box. Html: <select id="city_select" disabled="true" name="location_id" onchange="show_search_button();"><option selected>Select your city</option> </select> Javascript: document.getElementById('city_select').innerHTML = "<option selected>Select your city</option>"; I've also tried using location_id instead of city_select in the javascript but to no avail.. innerText and innerContent dont work either.. though the inner.HTML works in IE8 for an earlier function, but that isnt trying to innerHTML into a form. Does anybody know why this works in Chrome and FF but not IE8? and is there a solution to this? Any help appreciated thanks!

  • MVC2: Validate PartialView before Form Submit of Page containing Partial View

    - by Pascal
    I am using asp.net mvc2 and having a basic Page that includes a Partial View within a form <% using (Html.BeginForm()) { %> <% Html.RenderAction("partialViewActionName", "Controllername"); %> <input type="submit" value="Weiter" /> <% } %> When I submit the form, the httpPost Action of my Page is called, and AFTER that the httpPost Action of my Partial View is called [HttpPost] public virtual ActionResult PagePostMethod(myModel model) { // here I should know about the validation of my partial View // If partialView.ModelState is valid then // return View("success"); // else return View(model) } [HttpPost] public virtual ActionResult partialViewActionName(myModel model) { ModelState.AddModelError("Error"); return View(model); } But as I am doing the Validation in the httpPost Method of my Partial View (because I want to use my Partial View in several Places) I cant decide if my hole page is valid or not. Has anyone an Idea how I could do this? Isn´t it a common task to have several partial Views in a page but have the information about validation in the page action methods? Thanks very much for your help!!

  • How can I force Javascript garbage collection in IE? IE is acting very slow after AJAX calls & DOM

    - by RenderIn
    I have a page with chained drop-downs. Choosing an option from the first select populates the second, and choosing an option from the second select returns a table of matching results using the innerHtml function on an empty div on the page. The problem is, once I've made my selections and a considerable amount of data is brought onto the page, all subsequent Javascript on the page runs exceptionally slowly. It seems as if all the data I pulled back via AJAX to populate the div is still hogging a lot of memory. I tried setting the return object which contains the AJAX results to null after calling innerHtml but with no luck. Firefox, Safari, Chrome and Opera all show no performance degradation when I use Javascript to insert a lot of data into the DOM, but in IE it is very apparent. To test that it's a Javascript/DOM issue rather than a plain old IE issue, I created a version of the page that returns all the results on the initial load, rather than via AJAX/Javascript, and found IE had no performance problems. FYI, I'm using jQuery's jQuery.get method to execute the AJAX call. EDIT This is what I'm doing: <script type="text/javascript"> function onFinalSelection() { var searchParameter = jQuery("#second-select").val(); jQuery.get("pageReturningAjax.php", {SEARCH_PARAMETER: searchParameter}, function(data) { jQuery("#result-div").get(0).innerHtml = data; //jQuery("#result-div").html(data); //Tried this, same problem data = null; }, "html"); } </script>

  • how to use nokogiri methods .xpath & .at_xpath

How is possible to remove an element from the xpath to get things work? do I have to use .xpath twice to extract data if not using full xpath? why I cannot make .at_xpath working to extract data? it works nicely here what is the difference?

  • Getting fields_for and accepts_nested_attributes_for to work with a belongs_to relationship

    - by Billy Gray
    I cannot seem to get a nested form to generate in a rails view for a belongs_to relationship using the new accepts_nested_attributes_for facility of Rails 2.3. I did check out many of the resources available and it looks like my code should be working, but fields_for explodes on me, and I suspect that it has something to do with how I have the nested models configured. The error I hit is a common one that can have many causes: '@account[owner]' is not allowed as an instance variable name Here are the two models involved: class Account < ActiveRecord::Base # Relationships belongs_to :owner, :class_name => 'User', :foreign_key => 'owner_id' accepts_nested_attributes_for :owner has_many :users end class User < ActiveRecord::Base belongs_to :account end Perhaps this is where I am doing it 'rong', as an Account can have an 'owner', and may 'users', but a user only has one 'account', based on the user model account_id key. This is the view code in new.html.haml that blows up on me: - form_for :account, :url => account_path do |account| = account.text_field :name - account.fields_for :owner do |owner| = owner.text_field :name And this is the controller code for the new action: class AccountsController < ApplicationController # GET /account/new def new @account = Account.new end end When I try to load /account/new I get the following exception: NameError in Accounts#new Showing app/views/accounts/new.html.haml where line #63 raised: @account[owner] is not allowed as an instance variable name If I try to use the mysterious 'build' method, it just bombs out in the controller, perhaps because build is just for multi-record relationships: class AccountsController < ApplicationController # GET /account/new def new @account = Account.new @account.owner.build end end You have a nil object when you didn't expect it! The error occurred while evaluating nil.build If I try to set this up using @account.owner_attributes = {} in the controller, or @account.owner = User.new, I'm back to the original error, "@account[owner] is not allowed as an instance variable name". Does anybody else have the new accepts_nested_attributes_for method working with a belongs_to relationship? Is there something special or different you have to do? All the official examples and sample code (like the great stuff over at Ryans Scraps) is concerned with multi-record associations.

  • How to pass a parameter to jQuery UI dialog event handler?

    - by bebraw
    I am currently trying to hook up jQuery UI dialog so that I may use it to create new items to my page and to modify ones existing already on the page. I managed in the former. I'm currently struggling in the latter problem, however. I just cannot find a nice way to pass the item to modify to the dialog. Here's some code to illustrate the issue better. Note especially the part marked with XXX. The {{}} parts are derived from Django template syntax: $(".exercise").click(function() { $.post("{{ request.path }}", { action: "create_dialog", exercise_name: $(this).text() }, function(data) { $("#modify_exercise").html(data.content); }, "json" ); $("#modify_exercise").dialog('open'); }); $("#modify_exercise").dialog({ autoOpen: false, resizable: false, modal: true, buttons: { '{% trans 'Modify' %}': function() { var $inputs = $('#modify_exercise :input'); var post_values = {}; $inputs.each(function() { post_values[this.name] = $(this).val(); }); post_values.action = 'validate_form'; //XXX: how to get the exercise name here? post_values.exercise_name = 'foobar'; $.post('{{ request.path }}', post_values, function(data) { if( data.status == 'invalid' ) { $('#modify_exercise').html(data.content); } else { location.reload(); } }, "json" ); } } }); Here's some markup to show how the code relates to the structure: <div id="modify_exercise" class="dialog" title="{% trans 'Modify exercise' %}"> </div> <ul> {% for exercise in exercises %} <li> <a class="exercise" href="#" title="{{ exercise.description }}"> {{ exercise.name }} </a> </li> {% endfor %} </ul>

  • how to 'load data infile' on amazon RDS?

    - by feydr
    not sure if this is a question better suited for serverfault but I've been messing with amazon RDS lately and was having trouble getting 'file' privileges to my web host mysql user. I'd assume that a simple: grant file on *.* to 'webuser@'%'; would work but it does not and I can't seem to do it with my 'root' user as well. What gives? The reason we use load data is because it is super super fast for doing thousands of inserts at once. anyone know how to remedy this or do I need to find a different way? This page, http://docs.amazonwebservices.com/AmazonRDS/latest/DeveloperGuide/index.html?Concepts.DBInstance.html seems to suggest that I need to find a different way around this. Help? UPDATE I'm not trying to import a database -- I just want to use the file load option to insert several hundred-thousand rows at a time. after digging around this is what we have: mysql> grant file on *.* to 'devuser'@'%'; ERROR 1045 (28000): Access denied for user 'root'@'%' (using password: YES) mysql> select User, File_priv, Grant_priv, Super_priv from mysql.user; +----------+-----------+------------+------------+ | User | File_priv | Grant_priv | Super_priv | +----------+-----------+------------+------------+ | rdsadmin | Y | Y | Y | | root | N | Y | N | | devuser | N | N | N | +----------+-----------+------------+------------+

  • MVC controller is being called twice

    - by rboarman
    Hello, I have a controller that is being called twice from an ActionLink call. My home page has a link, that when clicked calls the Index method on the Play controller. An id of 100 is passed into the method. I think this is what is causing the issue. More on this below. Here are some code snippets: Home page: <%= Html.ActionLink(“Click Me”, "Index", "Play", new { id = 100 }, null) %> Play Controller: public ActionResult Index(int? id) { var settings = new Dictionary<string, string>(); settings.Add("Id", id.ToString()); ViewData["InitParams"] = settings.ToInitParams(); return View(); } Play view: <%@ Page Title="" Language="C#" Inherits="System.Web.Mvc.ViewPage" %> (html <head> omitted for brevity) <body> <form id="form1" runat="server" style="height:100%"> Hello </form> </body> If I get rid of the parameter to the Index method, everything is fine. If I leave the parameter in place, then the Index method is called with 100 as the id. After returning the View, the method is called a second time with a parameter of null. I can’t seem to figure out what is triggering the second call. My first thought was to add a specific route like this: routes.MapRoute( "Play", // Route name "Play/{id}", // URL with parameters new {controller = "Play", action = "Index"} // Parameter defaults ); This had no effect other than making a prettier looking link. I am not sure where to go from here. Thank you in advance. Rick

  • Play mp3 using Python, PyQt, and Phonon

    - by KeyboardInterrupt
    I been trying all day to figure out the Qt's Phonon library with Python. My long term goal is to see if I could get it to play a mms:// stream, but since I can't find an implementation of this done anywhere, I will figure that part out myself. (figured I'd put it out there if anyone knew more about this specifically, if not no big deal.) Anyway, I figured I'd work backwards from a working example I found online. This launches a file browser and will play the mp3 file specified. I wanted to strip out the file browser stuff and get it down to the essentials of executing the script and having it play an Mp3 file with a hardcoded path. I'm assuming my problem is a misunderstanding of setCurrentSource() and specifying the data types. (see: http://www.riverbankcomputing.co.uk/static/Docs/PyQt4/html/phonon-mediasource.html#fileName) I'm keeping my question kind of broad because ANY help with understanding Phonon would be greatly appreciated. import sys from PyQt4.QtGui import QApplication, QMainWindow, QDirModel, QColumnView from PyQt4.QtGui import QFrame from PyQt4.QtCore import SIGNAL from PyQt4.phonon import Phonon class MainWindow(QMainWindow): m_model = QDirModel() def __init__(self): QMainWindow.__init__(self) self.m_fileView = QColumnView(self) self.m_media = None self.setCentralWidget(self.m_fileView) self.m_fileView.setModel(self.m_model) self.m_fileView.setFrameStyle(QFrame.NoFrame) self.connect(self.m_fileView, SIGNAL("updatePreviewWidget(const QModelIndex &)"), self.play) def play(self, index): self.delayedInit() self.m_media.setCurrentSource( Phonon.MediaSource(self.m_model.filePath(index))) self.m_media.play() def delayedInit(self): if not self.m_media: self.m_media = Phonon.MediaObject(self) audioOutput = Phonon.AudioOutput(Phonon.MusicCategory, self) Phonon.createPath(self.m_media, audioOutput) def main(): app = QApplication(sys.argv) QApplication.setApplicationName("Phonon Tutorial 2 (Python)") mw = MainWindow() mw.show() sys.exit(app.exec_()) if __name__ == '__main__': main()

  • asp.net mvc, IIS 6 vs IIS7.5, and integrated windows authentication causing javascript errors?

    - by chris
    This is a very strange one. I have an asp.net MVC 1 app. Under IIS6, with no anon access - only integrated windows auth - every thing works fine. I have the following on most of my Foo pages: <% using (Html.BeginForm()) { %> Show All: <%= Html.CheckBox("showAll", new { onClick = "$(this).parent('form:first').submit();" })%> <% } %> Clicking on the checkbox causes a post, the page is reloaded, everything is good. When I look at the access logs, that's what I see, with one oddity - the js library is requested during the page first request, but not for any subsequent page requests. Log looks like: GET / 401 GET / 200 GET /Content/Site.css 304 GET /Scripts/jquery-1.3.2.min.js 401 GET /Scripts/jquery-ui-1.7.2.custom.min.js 401 GET /Scripts/jquery.tablesorter.min.js 401 GET /Scripts/jquery-1.3.2.min.js 304 GET /Scripts/jquery-ui-1.7.2.custom.min.js 304 GET /Scripts/jquery.tablesorter.min.js 304 GET /Content/Images/logo.jpg 401 GET /Content/Images/logo.jpg 304 GET /Foo 401 GET /Foo 200 POST /Foo/Delete 302 GET /Foo/List 200 POST /Foo/List 200 This corresponds to home page, click on "Foo", delete a record, click a checkbox (which causes the 2nd POST). Under IIS7.5, it sometimes fails - the click on the check box doesn't cause a postback, but there are no obvious reasons why. I've noticed under IIS7.5 that every single page request re-issues the requests for the js libraries - the first one a 401, followed by either a 200 (OK) or 304 (not modified), as opposed to the above log extract where that only happened during the 1st request. Is there any way to eliminate the 401 requests? Could a timing issue have something to do with the click being ignored? Would increasing the number of concurrent connections help? Any other ideas? I'm at a bit of a loss to explain this.

  • Microsoft ODBC driver for Oracle Syntax error or access violation (-2147217900)

    - by Jan
    I have a large VB program that connects to Oracle database. strCn = "Driver={Microsoft ODBC for Oracle};" & _ "SERVER=PSPROD;" Set Cn = New ADODB.Connection Cn.ConnectionString = strCn Cn.CursorLocation = adUseNone Cn.Open There are many users of my program so I have a table that contains each user's login name and their access rights to the various tables. I create a recordset of all users when the program is started and then select USERNAME and GRANTED_ROLE from the record set where USERNAME and PASSWORD are found. I use a "Set role 'GRANTED_ROLE' identified by 'password'" statment and Cn.Execute statement to set up the user's access rights. This is all done in a Module. On a form, I want to call a Stored Procedure that will SELECT, INSERT and UPDATE information into another schema's tables. I am able to call and run the stored procedure when I create a new connection to the database with this code: Dim cmd5040 As ADODB.Command Dim conn5040 As ADODB.Connection Dim param5040 As ADODB.Parameter Set conn5040 = New ADODB.Connection conn5040 = "Driver={Microsoft ODBC for Oracle};" & _ "SERVER=PSPROD; UID=XXXXXXX; PWD=XXXXXXXX" conn5040.Open Set cmd5040 = New ADODB.Command With cmd5040 .ActiveConnection = conn5040 .CommandType = adCmdStoredProc .CommandText = "S4115040_IMPORT_NEWBIDITEMSPES.S4115040_CheckTime" .Parameters.Append .CreateParameter(, adInteger, adParamInputOutput, 5) .Parameters.Append .CreateParameter(, adVarChar, adParamInputOutput, 400) End With cmd5040(0) = 0 cmd5040(1) = "" cmd5040.CommandTimeout = 300 cmd5040.Execute conn5040.Close However, I get the error message "-2147217900 [Microsoft][ODCB driver for Oracle]Syntax error or access violation" when I attempt to use the same connection ('Cn') when the program first started. My code is: Dim cmd5040 As ADODB.Command Dim param5040 As ADODB.Parameter Set cmd5040 = New ADODB.Command With cmd5040 .ActiveConnection = Cn .CommandType = adCmdStoredProc .CommandText = "S4115040_IMPORT_NEWBIDITEMSPES.S4115040_CheckTime" .Parameters.Append .CreateParameter(, adInteger, adParamInputOutput, 5) .Parameters.Append .CreateParameter(, adVarChar, adParamInputOutput, 400) End With cmd5040(0) = 0 cmd5040(1) = "" cmd5040.Execute I have worked with my DBA. She has given me direct grants and direct execute privliges and I am still get the error message. What am I doing wrong? Should I be able to use the original connection to run a stored procedure? Or must I create a second connection?

  • how to access(read/write) local file system from webkit/javascript?

    - by ganapati hegde
    Hi, i am using Webkitgtk for rendering my HTML pages.Now,say i am browsing the page, i select some text while reading,i want to save/write down the selected text on my local file say /home/localfile.txt. Is any way to access(read/write) local file system using webkit? In case of firefox, i can do like below. try { netscape.security.PrivilegeManager.enablePrivilege("UniversalXPConnect"); } catch (e) { alert("Permission to save file was denied."); } var file = Components.classes["@mozilla.org/file/local;1"] .createInstance(Components.interfaces.nsILocalFile); file.initWithPath( "/home/localfile.txt" ); if ( file.exists() == false ) { alert( "Creating file... " ); file.create( Components.interfaces.nsIFile.NORMAL_FILE_TYPE, 420 ); } var outputStream = Components.classes["@mozilla.org/network/file-output-stream;1"] .createInstance( Components.interfaces.nsIFileOutputStream ); outputStream.init( file, 0x04 | 0x08 | 0x20, 420, 0 ); var output = "my data to be written to the local file"; var result = outputStream.write( output, output.length ); outputStream.close(); The above code is written in a javascript file and the js file is linked to the html file.When some text is selected,the js function will be called and action will be taken place.How can i achieve the same result using Webkit? Thanks...

  • Benchmark Linq2SQL, Subsonic2, Subsonic3 - Any other ideas to make them faster ?

    - by Aristos
    I am working with Subsonic 2 more than 3 years now... After Linq appears and then Subsonic 3, I start thinking about moving to the new Linq futures that are connected to sql. I must say that I start move and port my subsonic 2 with SubSonic 3, and very soon I discover that the speed was so slow thats I didn't believe it - and starts all that tests. Then I test Linq2Sql and see also a delay - compare it with Subsonic 2. My question here is, especial for the linq2sql, and the up-coming dotnet version 4, what else can I do to speed it up ? What else on linq2sql settings, or classes, not on this code that I have used for my messures I place here the project that I make the tests, also the screen shots of the results. How I make the tests - and the accurate of my measures. I use only for my question Google chrome, because its difficult for me to show here a lot of other measures that I have done with more complex programs. This is the most simple one, I just measure the Data Read. How can I prove that. I make a simple Thread.Sleep(10 seconds) and see if I see that 10 seconds on Google Chrome Measure, and yes I see it. here are more test with this Sleep thead to see whats actually Chrome gives. 10 seconds delay 100 ms delay Zero delay There is only a small 15ms thats get on messure, is so small compare it with the rest of my tests that I do not care about. So what I measure I measure just the data read via each method - did not count the data or database delay, or any disk read or anything like that. Later on the image with the result I show that no disk activity exist on the measures See this image to see what really I measure and if this is correct Why I chose this kind of test Its simple, it's real, and it's near my real problem that I found the delay of subsonic 3 in real program with real data. Now lets tests the dals Start by see this image I have 4-5 calls on every method, the one after the other. The results are. For a loop of 100 times, ask for 5 Rows, one not exist, approximatively.. Simple adonet:81ms SubSonic 2 :210ms linq2sql :1.70sec linq2sql using CompiledQuery.Compile :239ms Subsonic 3 :15.00sec (wow - extreme slow) The project http://www.planethost.gr/DalSpeedTests.rar Can any one confirm this benchmark, or make any optimizations to help me out ? Other tests Some one publish here this link http://ormbattle.net/ (and then remove it - don not know why) In this page you can find a really useful advanced tests for all, except subsonic 2 and subsonic 3 that I have here ! Optimizing What I really ask here is if some one can now any trick how to optimize the DALs, not by changing the test code, but by changing the code and the settings on each dal. For example... Optimizing Linq2SQL I start search how to optimize Linq2sql and found this article, and maybe more exist. Finally I make the tricks from that page to run, and optimize the code using them all. The speed was near 1.50sec from 1.70.... big improvement, but still slow. Then I found a different way - same idea article, and wow ! the speed is blow up. Using this trick with CompiledQuery.Compile, the time from 1.5sec is now 239ms. Here is the code for the precompiled... Func<DataClassesDataContext, int, IQueryable<Product>> compiledQuery = CompiledQuery.Compile((DataClassesDataContext meta, int IdToFind) => (from myData in meta.Products where myData.ProductID.Equals(IdToFind) select myData)); StringBuilder Test = new StringBuilder(); int[] MiaSeira = { 5, 6, 10, 100, 7 }; using (DataClassesDataContext context = new DataClassesDataContext()) { context.ObjectTrackingEnabled = false; for (int i = 0; i < 100; i++) { foreach (int EnaID in MiaSeira) { var oFindThat2P = compiledQuery(context, EnaID); foreach (Product One in oFindThat2P) { Test.Append("<br />"); Test.Append(One.ProductName); } } } } Optimizing SubSonic 3 and problems I make many performance profiling, and start change the one after the other and the speed is better but still too slow. I post them on subsonic group but they ignore the problem, they say that everything is fast... Here is some capture of my profiling and delay points inside subsonic source code I have end up that subsonic3 make more call on the structure of the database rather than on data itself. Needs to reconsider the hole way of asking for data, and follow the subsonic2 idea if this is possible. Try to make precompile to subsonic 3 like I did in linq2Sql but fail for the moment... Optimizing SubSonic 2 After I discover that subsonic 3 is extreme slow, I start my checks on subsonic 2 - that I have never done before believing that is fast. (and it is) So its come up with some points that can be faster. For example there are many loops like this ones that actually is slow because of string manipulation and compares inside the loop. I must say to you that this code called million of times ! on a period of few minutes ! of data asking from the program. On small amount of tables and small fields maybe this is not a big think for some people, but on large amount of tables, the delay is even more. So I decide and optimize the subsonic 2 by my self, by replacing the string compares, with number compares! Simple. I do that almost on every point that profiler say that is slow. I change also all small points that can be even a little faster, and disable some not so used thinks. The results, 5% faster on NorthWind database, near 20% faster on my database with 250 tables. That is count with 500ms less in 10 seconds process on northwind, 100ms faster on my database on 500ms process time. I do not have captures to show you for that because I have made them with different code, different time, and track them down on paper. Anyway this is my story and my question on all that, what else do you know to make them even faster... For this measures I have use Subsonic 2.2 optimized by me, Subsonic 3.0.0.3 a little optimized by me, and Dot.Net 3.5
