• How do I lock the workstation from a windows service?

  - by Brad Mathews

  Hello, I need to lock the workstation from a windows service written in VB.Net. I am writing the app on Windows 7 but it needs to work under Vista and XP as well. User32 API LockWorkStation does not work as it requires an interactive desktop and I get return value of 0. I tried calling %windir%\System32\rundll32.exe user32.dll,LockWorkStation from both a Process and from Shell, but still nothing happens. Setting the service to interact with the desktop is a no-go as I am running the service under the admin account so it can do some other stuff that requires admin rights - like disabling the network, and you can only select the interact with desktop option if running under Local System Account. That would be secondary question - how to run another app with admin rights from a service running under Local System Account without bugging the user. I am writing an app to control my kids computer/internet access (which I plan to open source when done) so I need everything to happen as stealthily as possible. I have a UI that handles settings and status notifications in the taskbar, but that is easy to kill and thus defeat the locking. I could make another hidden Windows Forms app to handle the locking, but that just seems a rather inelegant solution. Better ideas anyone? Thanks! Brad

• Dynamic Column that contains a Repeater

  - by djbyter

  How would I go about doing this programatically? I can do this just fine declaratively, using a template column and then using something like this: ... <TemplateGridColumn> <ItemTemplate> <div> <asp:Image ID="groupImg" CssClass="groupImg" runat="server"/> <asp:Repeater ID="groupItemRpt" runat="server"> <HeaderTemplate> <ul class="groupItemList"> </HeaderTemplate> <ItemTemplate> <li> <asp:Image ID="itemImg" runat="server" /> <asp:HiddenField ID="itemValue" runat="server" /> </li> </ItemTemplate> <FooterTemplate> </ul> </FooterTemplate> </asp:Repeater> </div> </ItemTemplate> </TemplateGridColumn> ... I am dynamically creating this grid based on the data, so I'm already added columns with one set of controls. But now I need to figure out how to show multiple images, which expand/contract if the groupImg image control is clicked (i just toggle the ul) .. Can anyone point me in the right direction? Thanks.

• TemplateField button causing GridView Invalid Postback

  - by Carter

  Ok, so I've got a template field in a gridview that contains just a simple button... <asp:GridView ID="KeywordsGridView" AllowPaging="false" AutoGenerateColumns="false" BackColor="white" GridLines="None" HeaderStyle-CssClass="Table_Header" RowStyle-CssClass="Table_Style" runat="server"> <Columns> <asp:TemplateField> <ItemTemplate> <asp:Button runat="server" /> </ItemTemplate> </asp:TemplateField> <asp:BoundField DataField="References" SortExpression="References" HeaderText="Total References" /> <asp:BoundField DataField="Keyword" SortExpression="Keyword" HeaderText="Keyword" /> </Columns> </asp:GridView> Whenever I click the button I get the error... Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation. I've found a decent amount of articles referencing this issue, including a couple on SO, for example... http://stackoverflow.com/questions/228969/asp-net-invalid-postback-or-callback-argument-event-validation-is-enabled-usi and... http://stackoverflow.com/questions/103560/invalid-postback-or-callback-argument I might just be misunderstanding, but as far as I can tell they don't really help me. How do I get this to go away without setting enableEventValidation="false"?

• Web Start Application built on NetBeans Platform doesn't create desktop shortcut & start menu item

  - by rudolfv

  I've created a NetBeans Platform application that is launched using Java Web Start. I built the WAR file using the 'Build JNLP Application'-command in Netbeans. I've added a desktop shortcut and menu item to the JNLP file, but for some reason, these are not created when the application is launched. However, when I go to: Control Panel - Java - Temporary Internet Files - View - Select my application Click 'Install shortcuts to the selected application' the desktop and menu shortcuts are created correctly. Also, in the Java Console, the Shortcut Creation option is set to the following (the default, I presume): Prompt user if hinted Below is a snippet of my JNLP file: <jnlp spec="6.0+" codebase="$$codebase"> <information> <title>${app.title}</title> <vendor>SomeVendor (Pty) Ltd</vendor> <description>Some description</description> <icon href="${app.icon}"/> <shortcut online="true"> <desktop/> <menu submenu="MyApp"/> </shortcut> </information> ... I'm stumped. Does anybody have an explanation for this? Thanks PS This is on both Windows XP and Windows 7. NetBeans version: 6.8

• How to target multiple versions of .NET Framework from MSBuild?

  - by McKAMEY

  I am improving the builds for an open source project which currently supports .NET Framework v2.0, v3.5, and now v4.0. Up until now, I've restricted myself to v2.0 to ensure compatibility, but with VS2010 I am interested in having real targeted builds. I'm looking for some guidance on how to edit the MSBuild csproj/sln to be able to cleanly produce builds for each target. I'm willing to have complexity in the csproj and in a batch file to control the build. My goal is to be able to have a command line script that could produce the builds without needing Visual Studio installed, but only the necessary .NET Framework(s). Ideally, I'd like to minimize dependencies on additional software. I notice that a lot of people use NAnt (e.g. Ninject builds many targets with NAnt) but I'm unsure if this is necessary or if they are just more familiar with it. I'm pretty sure this can be done but am having trouble finding a definitive guide on setting it up and best practices. Bonus: my next step after getting this set up will be to better support Mono Framework. Any help on doing this same thing for Mono would be much appreciated.

• How do you keep the text selection on a DataGridView?

  - by fneep

  I'm running C# 2.0, and I've written an application with a DataGridView in virtualmode and a TreeView in the same form, but in different panels of a SplitContainer. My application has a "find all" function that finds all instances of a certain string, and adds them as the child nodes to a new node to the TreeView (it's a tree view because you can have multiple search results by having different root nodes). That idea is that when you click on one of those search results in the TreeView, that it would select the specific text of that result in the DataGridView (Virtually the same as Notepad++'s find all function) When I click on the TreeView, it does set the selected cell of the DataGridView and highlight the specific text, but it loses that specific text selection instantly (but keeps the cell selection) because by clicking on the TreeView the DataGridView loses focus. Here's the code for the AfterSelect of the TreeView: private void Tree_Results_AfterSelect(object sender, TreeViewEventArgs e) { if (e.Node.Level > 0) { SearchResult SelectedItem = (SearchResult)Tree_Results.SelectedNode.Tag; DataViewMain.CurrentCell = DataViewMain[SelectedItem.TypeIndex, SelectedItem.LineIndex]; DataViewMain.BeginEdit(false); DataGridViewTextBoxEditingControl SelectionData = (DataGridViewTextBoxEditingControl)DataViewMain.EditingControl; SelectionData.SelectionStart = SelectedItem.HighlightStart; SelectionData.SelectionLength = SelectedItem.HightlightLength; } } If the DataGridView were a text box I could possibly set HideSelection to false, but DataGridViews have no such property (and changing the Hide Selection for the EditingControl does nothing) Any ideas? I'm receptive to a different control instead of a TreeView that would allow my DataGridView to retain focus.

• Why avoid increment ("++") and decrement ("--") operators in JavaScript?

  - by artlung

  I'm a big fan of Douglas Crockford's writing on JavaScript, particularly his book JavaScript: The Good Parts. It's made me a better JavaScript programmer and a better programmer in general. One of his tips for his jslint tool is this : ++ and -- The ++ (increment) and -- (decrement) operators have been known to contribute to bad code by encouraging excessive trickiness. They are second only to faulty architecture in enabling to viruses and other security menaces. There is a plusplus option that prohibits the use of these operators. This has always struck my gut as "yes, that makes sense," but has annoyed me when I've needed a looping condition and can't figure out a better way to control the loop than a while( a < 10 )do { a++ } or for (var i=0;i<10;i++) { } and use jslint. It's challenged me to write it differently. I also know in the distant past using things, in say PHP like $foo[$bar++] has gotten me in trouble with off-by-one errors. Are there C-like languages or other languages with similarities that that lack the "++" and "--" syntax or handle it differently? Are there other rationales for avoiding "++" and "--" that I might be missing? UPDATE -- April 9, 2010: In the video Crockford on JavaScript -- Part 5: The End of All Things, Douglas Crockford addresses the ++ issue more directly and with more detail. It appears at 1:09:00 in the timeline. Worth a watch.

• Using hg repository as web site

  - by Tex

  This is somewhat related to my security question here. Is it a bad idea to use an hg / mercurial repository for a live website? If so, why? Furthermore, we have dev, test and production installations of our website, like dev.example.com, test.example.com and www.example.com. If it's a bad idea to use a repository for a live/production website, would it be OK to use an hg repository for the dev and test sites? I'm also concerned about ease of deployment. We have technical and less technical co-workers who will be working with the site. The technical guys (software engineers) won't have any problem working with the command line or TortoiseHG. I'm more concerned about the less technical guys (web designers). They won't be comfortable working on the command line, and may even find TortoiseHG daunting. These guys mostly upload .css files and images to the server. I'd like for these files (at least the .css files) to be under version control, but I want this to be as transparent as possible for the non technical guys. What's the best way to achieve this? Edit: Our 'site' is actually a multi-site CMS setup with a main repository and several subrepositories. Mock-up of the repository structure: /root [main repository containing core files and subrepositories] /modules [modules subrepository] /sites/global [subrepository for global .css and .php files] /sites/site1 [site1 subrepository] ... /sites/siteN [siteN subrepository] Software engineers would work in the root, modules and sites/global repositories. Less technical guys (web designers) would work only in the site1 ... siteN subrepositories.

• Subscription website architecture questions + SQL Server & .NET

  - by chopps

  Hey Guys, I have a few questions about the architecture of a subscription service I am about to embark on and I am looking for some feedback on how best to set it up. I won’t have a large amount of customers as Basecamp, maybe a few hundred and was wondering what would be a solid architecture for setting up the customer sites. I’m running SQL Server and .NET on a dedicated machine. Should create a new database for each customer as to have control and isolation of data or keep them all in one database? I am also thinking of creating a sub-domain for each customer as well so modifications can be made to each site as needed. The customer URLs would look like this: https://customer1.foobar.com https://customer2.foobar.com I am going to have the ability to ‘plug-in’ reports that will be uploaded to the site so each customer can customize as needed. Off the top of my head this necessitates having each sub domain on its own code-base for the uploading of these reports. So on the main site the customer would sign up for their new subscription and I would programmatically create a new directory for the customer from the main code base and then create a sub domain pointing to the new directory for the customer and then finally their database. Does this sound about right? Am I on the right track? How do other such sites accomplish the same thing? Thanks for letting me bend your ear for a bit on this.

• How do I reference an unsigned assembly from a VSTO Word Doc project?

  - by Gishu

  I created a new project in VS2008. Project type Visual C# > Office > 2007 > Word 2007 Document Added some code.. got Word to do a few jumps through some custom hoops.. all fine. Now I need to reference another assembly (CopyLocal as false) which is not signed. So I add the project reference. Now the project will not build complaining error MSB3188: Assembly 'X.dll' must be strong signed in order to be marked as a prerequisite. The error code page is concise (now accustomed to this) Been googling and reading posts ever since.. No Luck. How do I get around this ? Or is the hidden commandment that all references (for VSTO?) must be strong named / signed. I cannot sign 'X.dll' and be done with it because it is a binary that I don't control also it depends on another bunch of unsigned dlls.. can't set off a chain sign reaction. Update: Solved the build issue by turning CopyLocal=True. But this meant dumping the referenced X.DLL and all its dependencies into the bin\debug folder... Ughh! Tried creating a subfolder called bin\debug\refExecs and referencing X.dll CopyLocal=false from there. The error message was back.

I have done the following steps I have installed subversion is c:\program files\collabnet\ and the root for the repositories in e:\svn_repository I then created a repository as e:\svn_repository\lemon I then edited the passwd file and added the user and password I then tried importing an existing project into the repository with the address - svn://localhost/lemon with the new user and password. After all this, i get the error "authentication failed"... I am pretty sure the authentication is correct...

• Customising Flex Datagrid or alternative solutions

  - by Martin

  I'm currently building an application that is presenting tabular (fetched from a webservice) data and have squirted it into a datagrid - seemed the most obvious way to present it on screen. I've now come across a few limitations in the datagrid and wonder how I might move forward. As a relative newcomer to flex development I'm a little lost. A few things I am wanting to do. The data is logically split into groups and I would like to be able to have subheadings in the grid whenever I move to a new group. I would like to be able to highligh individual cells based on their content relative to other values in the row - ie highlight the cell with the highest value in the row. Is this possible with the standard datagrid? I'm actually using the try-before-you-buy version of flex builder at the moment but I have ordered Flex Builder 3 Pro - which is on its way to me. I understand there is an 'advanced datagrid' control in this version - perhaps that will support some of what I wish to do? Alternatively - is there another way of building custom tabular data?

• How test that ASP.NET MVC route redirects to other site?

  - by Matt Lacey

  Due to a prinitng error in some promotional material I have a site that is receiving a lot of requests which should be for one site arriving at another. i.e. The valid sites are http://site1.com/abc & http://site2.com/def but people are being told to go to http://site1.com/def. I have control over site1 but not site2. site1 contains logic for checking that the first part of the route is valid in an actionfilter, like this: public override void OnActionExecuting(ActionExecutingContext filterContext) { base.OnActionExecuting(filterContext); if ((!filterContext.ActionParameters.ContainsKey("id")) || (!manager.WhiteLabelExists(filterContext.ActionParameters["id"].ToString()))) { if (filterContext.ActionParameters["id"].ToString().ToLowerInvariant().Equals("def")) { filterContext.HttpContext.Response.Redirect("http://site2.com/def", true); } filterContext.Result = new ViewResult { ViewName = "NoWhiteLabel" }; filterContext.HttpContext.Response.Clear(); } } I'm not sure how to test the redirection to the other site though. I already have tests for redirecting to "NoWhiteLabel" using the MvcContrib Test Helpers, but these aren't able to handle (as far as I can see) this situation. How do I test the redirection to antoher site?

• ASP.NET MVC 2 DisplayFor()

  - by ZombieSheep

  I'm looking at the new version of ASP.NET MVC (see here for more details if you haven't seen it already) and I'm having some pretty basic trouble displaying the content of an object. In my control I have an object of type "Person", which I am passing to the view in ViewData.Model. All is well so far, and I can extact the object in the view ready for display. What I don't get, though, is how I need to call the Html.DisplayFor() method in order to get the data to screen. I've tried the following... <% MVC2test.Models.Person p = ViewData.Model as MVC2test.Models.Person; %> // snip <%= Html.DisplayFor(p => p) %> but I get the following message: CS0136: A local variable named 'p' cannot be declared in this scope because it would give a different meaning to 'p', which is already used in a 'parent or current' scope to denote something else I know this is not what I should be doing - I know that redefining a variable will producte this error, but I don't know how to access the object from the controller. So my question is, how do I pass the object to the view in order to display its properties? (I should add that I am reading up on this in my limited spare time, so it is entirely possible I have missed something fundamental) TIA

• C# NullReferenceException when passing DataTable

  - by Timothy

  I've been struggling with a NullReferenceException and hope someone here will be able to point me in the right direction. I'm trying to create and populate a DataTable and then show the results in a DataGridView control. The basic code follows, and Execution stops with a NullReferenceException at the point where I invoke the new UpdateResults_Delegate. Oddly enough, I can trace entries.Rows.Count successfully before I return it from QueryEventEntries, so I can at least show 1) entries is not a null reference, and 2) the DataTable contains rows of data. I know I have to be doing something wrong, but I just don't know what. private delegate void UpdateResults_Delegate(DataTable entries); private void UpdateResults(DataTable entries) { dataGridView.DataSource = entries; } private void button_Click(object sender, EventArgs e) { Thread t = new Thread(new ThreadStart(PerformQuery)); t.Start(); } private void PerformQuery() { DateTime start = new DateTime(dateTimePicker1.Value.Year, dateTimePicker1.Value.Month, dateTimePicker1.Value.Day, 0, 0, 0); DateTime stop = new DateTime(dateTimePicker2.Value.Year, dateTimePicker2.Value.Month, dateTimePicker2.Value.Day, 0, 0, 0); DataTable entries = QueryEventEntries(start, stop); Invoke(new UpdateResults_Delegate(UpdateResults), entries); } private DataTable QueryEventEntries(DateTime start, DateTime stop) { DataTable entries = new DataTable(); entries.Columns.Add("colEventType", typeof(Int32)); entries.Columns.Add("colTimestamp", typeof(Int32)); entries.Columns.Add("colDetails", typeof(String)); ... conn.Open(); using (SqlDataReader r = cmd.ExecuteReader()) { while (r.Read()) { entries.Rows.Add(result.GetInt32(0), result.GetInt32(1), result.GetString(2)); } } return entries; }

• Web Automation Tool

  - by Aaron

  I've realized I need a full-fledged browser automation tool for testing user interactions with our JavaScript widget library. I was using qunit, starting with unit testing and then I unwisely started incorporating more and more functional tests. That was a bad idea: trying to simulate a lot of user actions with JavaScript. The timing issues have gotten out of control and have made the suite too brittle. Now I spend more time fixing the tests, then I do developing. Is it possible to find a browser automation tool that works in: Windows XP: IE6,7,8, FF3 OSX: Safari, FF3 ? I've looked into SeleniumIDE and RC, but there seems to be some IE8 problems. I've also seen some things about Google's WebDriver, which confusingly seems to work with Selenium. Our organziation has licenses for IBM's Rational Functional Tester, but I don' think that will work on the MAC. The idea is to try to run tests on all the browsers our organization supports. Doable? Are my requirements unrealistic? Any recommendations as far as software to try? Thanks!

• Forms/AD Authentication with Sharepoint

  - by David Lively

  All, I'm configuring Sharepoint to use forms authentication with LDAP/Active Directory. I'm new to Sharepoint, so if this is obvious, please point me in the right direction. Whenever I attempt to log in with a bad account or password, I get the very friendly (and correct) error message, The server could not sign you in. Make sure your user name and password are correct, and then try again. ... which implies that Sharepoint is able to communicate with AD. If I log in with a valid account, I get a page that says: (I added the grey bar to cover up the login name) Any suggestions? The account I'm logging in with is an administrator and has been granted full control in central administration. Also, interesting note: If I click the "sign in as a different user" link, and attempt to sign in using with the same credentials I just used, the site just redirects back to the login page, with no error or status message. If I then manually enter the site url, it again shows the "Error: Access Denied" page. Argh.

• Testing fault tolerant code

  - by Robert

  I’m currently working on a server application were we have agreed to try and maintain a certain level of service. The level of service we want to guaranty is: if a request is accepted by the server and the server sends on an acknowledgement to the client we want to guaranty that the request will happen, even if the server crashes. As requests can be long running and the acknowledgement time needs be short we implement this by persisting the request, then sending an acknowledgement to the client, then carrying out the various actions to fulfill the request. As actions are carried out they too are persisted, so the server knows the state of a request on start up, and there’s also various reconciliation mechanisms with external systems to check the accuracy of our logs. This all seems to work fairly well, but we have difficult saying this with any conviction as we find it very difficult to test our fault tolerant code. So far we’ve come up with two strategies but neither is entirely satisfactory: Have an external process watch the server code and then try and kill it off at what the external process thinks is an appropriate point in the test Add code the application that will cause it to crash a certain know critical points My problem with the first strategy is the external process cannot know the exact state of the application, so we cannot be sure we’re hitting the most problematic points in the code. My problem with the second strategy, although it gives more control over were the fault takes, is I do not like have code to inject faults within my application, even with optional compilation etc. I fear it would be too easy to over look a fault injection point and have it slip into a production environment.

• JQuery & Wordpress - Hide multiple divs inside unique ID?

  - by steelfrog

  I'm trying to write a short Wordpress JQuery for Wordpress comments that would allow users to toggle specific comments on and off. This is my first script, and I'm having a tough time. Once overtly simplified, the comments are formatted like so: <li id="li-comment-<?php comment_ID() ?>"> <div class="gravatar"><img src="#" /></div> <div class="comment_poster">Username</div> <div class="comment_options">Option buttons</div> <div class="comment_content">Comment</div> </li> In the "comment_options" DIV is a series of buttons that control the individual comments (reply, quote, edit, close, etc.). The close button is what I'm trying to write this script for. I need it to toggle the "gravtar" and "comment_content" DIVs, but leave the rest in place so that it still displays the user ID and controls. However, I can't seem to figure out how to contain the action. This is what I have so far: $(document).ready(function() { $("div.trigger").click(function() { $("div.gravatar").slideToggle(); $("div.comment_content").slideToggle(); }); }); The problem with this is that it closes are the .gravatar and .comment_content on the page, not just the ones found in the same list item. If you're curious, this is the page I'm working on. Any idea how I could resolve this? Again, this is my firs time with JQuery, so I'm a little fuzzy on how it all works. Thanks!

• What data structure to use / data persistence

  - by Dave

  I have an app where I need one table of information with the following fields: field 1 - int or char field 2 - string (max 10 char) field 3 - string (max 20 char) field 4 - float I need the program to filter on field 1 based upon a segmented control and select a field 2 from a picker. From this data I need to look up field 4 to use in a calculation. Total records will be about 200. I never see it go above 400 - 500. I am going to use a singleton which I am able to do, I just need help with the structure for this with data persistence. What type of data structure should I use for this and should I use NSNumber, NSString, etc. or old data types like float, Char, etc. I thought about a struct put into an array but there is probably a better way. This is new to me so any help or reference to examples would be great. I also thought about a plist or dictionary but it looks like it is just a lookup and a field which obviously won't work. Core data looked like overkill to me. Also, with any recommendation how should I get initial data into it? I want the user to be able to edit and add to the database. Sorry for the old terms, you can see what generation I am from... Thanks in advance!!!!

• Linux: How to find all serial devices (ttyS, ttyUSB and others)?

  - by Thomas Tempelmann

  What is the proper way to get a list of all available serial ports/devices on a Linux system? In other words, when I iterate over all devices in /dev/, how do I tell which ones are serial ports in the classic way, i.e. those usually supporting baud rates and RTS/CTS flow control? The solution would be coded in C. I ask because I am using a 3rd party library that does this clearly wrong: It appears to only iterate over /dev/ttyS*. The problem is that there are, for instance, serial ports over USB (provided by USB-RS232 adapters), and those are listed under /dev/ttyUSB*. And reading the Serial-HOWTO at Linux.org, I get the idea that there'll be other name spaces as well, as time comes. So I need to find the official way to detect serial devices. Problem is that there appears none documented, or I can't find it. I imagine one way would be to open all files from /dev/tty* and call a specific ioctl() on them that is only available on serial devices. Would that be a good solution, though?

When I submit the form, the Search property don't get bound properly. Everything is empty.The action takes an argument of ProjectSearch type. Why the Search don't get bound as supposed ?

• Flex - Increase timeout on a PHP service function call

  - by Travesty3

  I'm using Flash Builder 4 Beta 2. I have it connecting to a PHP service. The way I set this up was using the wizard, so I didn't actually write the code to connect to it. The service looks like this: package services.flash { import mx.rpc.AsyncToken; import com.adobe.fiber.core.model_internal; import mx.rpc.AbstractOperation; import valueObjects.CustomDatatype8; import valueObjects.NewUsageData; import mx.collections.ItemResponder; import mx.rpc.remoting.RemoteObject; import mx.rpc.remoting.Operation; import com.adobe.fiber.services.wrapper.RemoteObjectServiceWrapper; import com.adobe.fiber.valueobjects.AvailablePropertyIterator; import com.adobe.serializers.utility.TypeUtility; [ExcludeClass] internal class _Super_FLASH extends RemoteObjectServiceWrapper { // Constructor public function _Super_FLASH() { // initialize service control _serviceControl = new RemoteObject(); var operations:Object = new Object(); var operation:Operation; operation = new Operation(null, "sendCommand"); operation.resultType = Object; operations["sendCommand"] = operation; ... } } One of the functions that I'm calling fetches users from a MySQL database. There are about 30,000 users right now. The service seems to timeout when fetching more than around 22,000 rows, I get the "Channel Disconnected before an acknowledgement was received" error. If I call the PHP script from a browser, it fetches them all with no problems at all, however. I have tried increasing the timeout in the PHP script (which didn't work), but obviously this isn't the problem since the browser is able to pull them up with no problems. Is there a way to increase the timeout of the PHP service in Flash Builder? I'm a bit of a noob when it comes to Flash, so please be descriptive. Thanks in advance!
