Reapplying changelist in perforce

- by Niklas

I'm rather new to perforce, but have quite a bit of other VCS experience... Imagine this: You submit changes (changelist 1) A colleague submits changes on the same branch, accidentally overwriting your changes. (changelist 2) I tried integrating (which P4V refuses to do since it's already integrated) and looked around for a way to just generate a patch that I could apply, but couldn't find anything. For now, I will check out the versions in question and use an external merge tool, but it would be great to know if perforce supports this somehow. Is there a way using the perforce tools (preferably in P4V) to reapply changelist 1?

Model Binding an IList of selected items only

- by jeef3

I have an action method setup: public ActionResult Delete(IList<Product> products) And a table of products in my view. I have got Model Binding working so that on submit I can populate the products list. But I would like to populate it with only the products that are selected via a checkbox. I think I could do it by changing the action method to this: public ActionResult Delete(IList<Product> products, IList<int> toDelete) And passing the list of check boxes to the toDelete but I would really like to avoid changing the method signature if possible. Is there a way to pass only the selected items? Or am I going to have to write a custom ModelBinder?

- by vimalkumar G

Is it possible to take a screenshot of a web page with ASP.net with C# Code and then submit that back to the server? In this code access only local host only, but same source code not access to the IIS, CopyFromScreen error ware occurred. What is the reason is it possible? Sample Source Code: Bitmap Bitmap; Graphics Graps; Bitmap = new Bitmap(Screen.PrimaryScreen.Bounds.Width, Screen.PrimaryScreen.Bounds.Height - 110, PixelFormat.Format32bppArgb); Graps = Graphics.FromImage(Bitmap); Graps.CopyFromScreen(Screen.PrimaryScreen.Bounds.X, 110, 0, 0, Screen.PrimaryScreen.Bounds.Size, CopyPixelOperation.SourceCopy); Bitmap.Save(Server.MapPath("~") + "/YourShot.gif");

SelectedValue of DropDownList is not the one I selected when Enabled=false

- by anD666

Hiya, I have a few DropDownLists on a webform each pointing to a SqlDataSource. Some of these datasources use one of these DropDownLists for a select parameter, filtering the list to specific categories. For certain users two of these DropDownLists are to be automatically set and disabled. When I submit the form with the drop downs enabled it works fine but when they are disabled the SelectedValue of the DropDownList is being reset to the first one in the list. My DropDownLists are constructed as follows: <asp:DropDownList ID="ddlManager" runat="server" DataSourceID="dsManagers" EnableViewState="false" DataValueField="ManagerID" DataTextField="MgrName" AppendDataBoundItems="false" ondatabound="ddlManager_DataBound" > The drop down lists add an extra item on the data bound event as follows: protected void ddlManager_DataBound(object sender, EventArgs e) { this.ddlManager.Items.Insert(0, new ListItem("--Manager--", "--Manager--")); } Can anyone shed any light as to why this is happening? Thanks Andy

- by MobiHunterz

Hi, I'm using ICECAST and I'm streaming AAC/HE-AACv2 audio/video file through flash player and on iPhone. Both are separate. But when I submit url in WINAMP to stream it's requesting username/password. But when I use it with flash player, it just starts streaming. My case is I want to use same streaming (RTMP) for both website and iPhone app and i want to impose control access over my flash player to authenticate who can see streamed video. So, I need to allow access to authenticated users only to see flash player or just reject playing. Now, my provider is not supporting control access on flash player, but i need to do it... can u say how i can do this? Any kind of help will be appreciated. Thanks.

Customising event delegates in the jQuery validation plug-in

- by Russell

I am currently setting up the jQuery validation plug-in for use in our project. By default, there are some events automatically set up for handling. I.e. focus in/out, key up events on all inputs fire validation. I want it to only fire when the submit button is clicked. This functionality seems to be in-built into the plug-in, which is making it difficult to do this (without modifying the plug-in code, Not What I Want To Do). I have found the eventDelegate function calls in the plugin code prototype method: $(this.currentForm) .validateDelegate(":text, :password, :file, select, textarea", "focusin focusout keyup", delegate) .validateDelegate(":radio, :checkbox, select, option", "click", delegate); When I remove these lines from the plug-in I get my result, however I would much rather do something Outside the plug-in to achieve this. Can anybody please help me? If you need any more details, please let me know. I have searched google with little success. Thanks

How come module-level validators are evaluated only after property-level validators?

- by jonathanconway

I'm using the module-level validator: 'PropertiesMustMatch' on my view-model, like so: [PropertiesMustMatch("Password", "PasswordConfirm")] public class HomeIndex { [Required] public string Name { get; set; } public string Password { get; set; } public string PasswordConfirm { get; set; } } I'm noticing that if I submit the form without Name filled in, the ValidationSummary() helper returns only the following error: The Name field is required. However, if I fill in Name, then ValidationSummary() will return a PropertiesMustMatch error: 'Password' and 'PasswordConfirm' do not match. So it looks like the property-level validators are being evaluated first, then the model-level validators. I would much prefer if they were all validated at once, and ValidationSummary would return: The Name field is required. 'Password' and 'PasswordConfirm' do not match. Any ideas what I can do to fix this? I'm studying the MVC 2 source-code to try to determine why this happens.

CSS button not styling

- by o-logn

Hey, I must be missing something obvious, but can someone explain what I'm doing wrong with my CSS? I would like all buttons to have a certain format, except a few. I was expecting to use CssClass in order to override the few that should be different, but they all seem to use the standard one. My CSS: .btn { border:none; background-color:red; } input[type="submit"] { border: 2px solid black; background-color:green; } All the buttons take the second value (green background, with a border). However, I have this button: <asp:Button ID="btnAdd" CssClass="btn" runat="server" Text="Add" /> I was expecting this to have no border, and a red background, but it's the same as every other button. Any ideas what I'm doing wrong? Thanks

Ruby on Rails form_remote_tag missing template

- by Donald Hughes

I'm using form_remote_tag(:url => {:controller => "home", :action => "search"}, :update => "mydiv"). When I click submit on the form "mydiv" is populated with the error "Template is missing. Missing template home/search.erb in view path app/views". I've tried multiple render options in def search, but they all result in the same error. It looks like the search method is trying to use it's default render even though I'm specifying what I want. I've tried: render 'index' render :text => 'Return this from my method!' Is my url incorrect? Is it not submitting back to my home controller's search method?

NServiceBus is blocking when hosted in ASP.NET web application

- by Dale Niemeyer

Hello, I created a simple web application where a search form is filled out, submit button clicked, and a message is sent with the search parameters via nServiceBus. I also have a handler in the same project that picks up the message (from the same queue). For some reason, the web server process blocks until after the message is picked up, is there any reason for this? I set a breakpoint in the message handler and it breaks before the request finishes... locking the browser until I allow the code to continue. I would expect control to return to the browser regardless of when the handler gets fired... Thanks, D.Niemeyer

ASP.NET MVC: Triggering an action before posting to Paypal payment gateway

- by ajbeaven

I'm in the middle of developing an e-commerce site that is using Paypal as it's payment gateway. All I want to do is run some code before the user heads off to Paypal to pay for their order, but I have no idea how to do it. The user should click a submit button, changes are made (in this case, the status of the order), and then the user is redirected to the payment gateway. Eg: [AcceptVerbs(HttpVerbs.Post)] public ActionResult GoToPaypal(FormCollection collection) { //change order status //send user to paypal where they pay for their order } So my question is how do you do application stuff and then redirect to paypal's payment gateway? Example HTML and C# would be lovely :)

Although in firebug it shows that I have sent that text. Any ideas? Thanks :)

Prevent users from being able to access a webpage via web browser?

- by Rob

My friend and I are working on a program. This program is going to submit GET data to our webpage. However, we don't want users accessing the webpage any other way than the program. We can prevent users from sharing the program using HWID authentication, but nothing prevents them from using a packet scanner to get the URL of the webpage. We thought about user-agent authentication, which we will implement, but user-agents can easily be spoofed. So my question is, how can we prevent users from accessing the webpage directly, instead of through the program? Even if you don't have an answer that will completely work, anything that will help deter them would be nice. Currently we will be implementing: HWID Authentication to use the program User-Agent Authentication to access the web page Instant IP Blacklisting to anyone accessing the webpage without the proper User-Agent

ASP.NET MVC AJAX value not displaying

View: function success(arg) { var obj = arg.get_response().get_object(); if (obj.ErrorMessage === '') { var answer = document.createElement('div'); answer.appendChild(document.createTextNode(obj.Answer)); document.getElementById('answers').appendChild(answer); } else { document.getElementById('errors').innerHTML = obj.ErrorMessage; } } <% using (Ajax.BeginForm("EditOrganizationMeta", "Organization", new AjaxOptions { HttpMethod = "POST", OnSuccess = "success" })) { %> <input type="submit" name="button<%=OrganizationMeta.vcr_MetaKey + Lang.int_LangId %>" value="Save" /> <div id="errors"></div> <div id="answers"></div> <% } %> Controller: [HttpPost] [ValidateInput(false)] public ActionResult EditOrganizationMeta(FormCollection collection) { return Json(new { Answer = "Record Successfully Saved", ErrorMessages = "Title is required" }); } The thing is that success method in the javascript is not getting the required parameters. It is printing undefined there. Is there a problem in javascript method OnSuccess?

Is there a DRMAA Java library that works with Torque/PBS?

- by dondondon

Does anybody know a Java implementation of the DRMAA-API that is known to work with PBS/Torque cluster software? The background behind this: I would like to submit jobs to a newly set-up linux cluster from java using a DRMAA compliant API. The cluster is managed by PBS/Torque. Torque includes PBS DRMAA 1.0 library for Torque/PBS that contains a DRMA-C binding and provides in libdrmaa.so and .a binaries. I know that Sun grid engine includes a drmaa.jar providing a Java-DRMAA API. In fact I opted to use SGE but it was decided to try PBS first. The theory behind that decision was: 'DRMAA is a standard and therefore a Java API needs only a standards compliant drmaa-c binding.' However, I couldn't find such 'general DRMAA-C-java API' and now assume that this assumption is wrong and that the Java libraries are engine specific. Are we stuck here? Any comments appreciated.

Security precautions and techniques for a User-submitted Code Demo Area

- by Jack W-H

Hey folks Maybe this isn't really feasible. But basically, I've been developing a snippet-sharing website and I would like it to have a 'live demo area'. For example, you're browsing some snippets and click the Demo button. A new window pops up which executes the web code. I understand there are a gazillion security risks involved in doing this - XSS, tags, nasty malware/drive by downloads, pr0n, etc. etc. etc. The community would be able to flag submissions that are blatantly naughty but obviously some would go undetected (and, in many cases, someone would have to fall victim to discover whatever nasty thing was submitted). So I need to know: What should I do - security wise - to make sure that users can submit code, but that nothing malicious can be run - or executed offsite, etc? For your information my site is powered by PHP using CodeIgniter. Jack

MySQL, C++: Retrieving auto-increment ID

- by Thomas Matthews

I have a table with an auto-incrementing ID. After inserting a new row, I would like to retrieve the new ID. I found an article that used the MySQL function LAST_INSERT_ID(). The article says to create a new query and submit it. I'm using MySQL Connector C++, Windows XP and Vista, and Visual Studio 9. Here are my questions: Is there an API, for the connector, that will fetch the ID out of the record? Does the result set, after an insert/append, contain the new ID? The LAST_INSERT_ID is MySQL specific. Is there an SQL standard method for obtaining the new ID?

How do you get notified of your repos' updates?

- by furtelwart

I'm working on several repositories at work and would like to be informed, if anything changes in the SVN repositories. I made a small BAT script (yes, BAT is usefull sometimes) that keeps executing an svn log -r BASE:HEAD on my working copy. It shows all submit comments and revision dates. It works really well but it's not comfortable for different repositories. How do you keep track of changes in your repositories? Do you use a small program you made for yourself? Do you use software someone else made? I'm interested in every approach to this problem. I would like to get notifications and several more information about the commit. The IDE integrated functions are good, but work only if I request the information. I don't want to act to get this information. Platform: Windows, Subversion 1.5 and higher.

Rails, using jQuery without jrails

- by ibuck

Hello all, I have been trying to convert my rails 2.2.2 app over to jQuery, and would like so without using jrails. The only reference material I can find on the subject is Railscasts Episode 136. Ryan goes over how to use jQuery to post a form and handle the response in a .js.erb file. My questions is has anyone tried to use jQuery with .js.erb files with anchors as the trigger? As a replacement for "link_to_remote". I have gotten jQuery to do a .get to submit this link on click to the controller, but I cannot seem to get it to go into the .js.erb file. Thanks

Rails: Need a helping hand to finish this Jquery/Ajax problem.

- by DJTripleThreat

Here's my problem: I have a combo box that when its index changes I want a div tag with the id="services" to repopulate with checkboxes based on that comboboxes value. I want this to be done using ajax. This is my first time working with ajax for rails so I need a helping hand. Here is what I have so far: My application.js file. Something that Ryan uses in one of his railscasts. This is supposed to be a helper method for handling ajax requests. Is this useful? Should I be using this?: //<![CDATA[ $.ajaxSetup({ 'beforeSend': function(xhr) {xhr.setRequestHeader("Accept","text/javascript")} }); // This function doesn't return any results. How might I change that? Or // should I have another function to do that? $.fn.submitWithAjax = function() { this.submit(function() { $.post($(this).attr("action"), $(this).serialize(), null, "script"); return true; }); }; //]]> An external javascript file for this template (/public/javascripts/combo_box.js): //<![CDATA[ $(document).ready(function(){ $('#event_service_time_allotment').change(function () { // maybe I should be using submitWithAjax(); ?? $(this).parent().submit(); }); }); //]]> My ???.js.erb file. I'm not sure where this file should go. Should I make an ajax controller?? Someone help me out with that part please. I can write this code no problem, I just need to know where it should go and what the file name should be called (best practices etc): // new.js.erb: dynamic choices... expecting a time_allotment alert('test'); // TODO: Return a json object or something with a result set of services // I should be expecting something like: // params[:event_service][:time_allotment] i think which I should use // to return a json object (??) to be parsed or rendered html // for the div#services. Here is my controller's new action. Am I supposed to respond to javascript here? Should I make an ajax controller instead? What's the best way to do this?: # /app/controllers/event_services_controller.rb def new @event_service = EventService.new respond_to do |format| format.html # new.html.erb format.xml { render :xml => @event_service } format.js # should I have a javascript handler here? i'm lost! end end My /app/views/event_service/new.html.erb. My ajax call I think should be a different action then the form: <% content_for :head do %> <%= javascript_include_tag '/javascripts/combo_box.js' %> <% end %> <% form_for @event_service, :url => admin_events_path, :html => {:method => :post} do |f| %>   <%= select("event_service", "time_allotment", TimeAllotment.all.collect {|ta| [ta.title, ta.value]}, {:prompt => true}) %> Services:  <div id="services"> <% for service_type in ServiceType.all %> <div> <%= check_box_tag "event_service[service_type_ids][]", service_type.id, false %> <%=h service_type.title %> </div> <% end %> </div> <% end %> ok so right now ALL of the services are there to be chosen from. I want them to change based on what is selected in the combobox event_service_time_allotment. Thanks, I know this is super complicated so any helpful answers will get an upvote.

Visual Studio bug ~ can anyone duplicate?

- by drachenstern

In Visual Studio 2010 Pro (Version 10.0.30319.1 RTMRel), I noticed tonight that for some reason I kept getting a wider window for quick find, but thought I was losing my mind. So I exited, restarted, etc to verify. Here's my repro steps Open existing project (I don't think it matters which one) Press ctrlf and give it something to search for (?) Press enter Press ctrlf Press enter goto 4 Can you reproduce a slowly expanding quick find window? Do I have some sort of wacky bugged out system? I'ld obviously like to submit a bug report to MS if this is indeed a viable repro.
