  • How to find where a library is used across multiple pom files

    - by Pablojim
    We have multiple maven projects depending on on our own common libraries. When we upgrade a library it would be useful to quickly find out which projects have a dependency on the library (and might need to use the new version) Obviously I can manually look in all the pom files or write a script to do it but this is less than ideal. Are there any tools that provide this functionality. e.g. a hudson plugin, Nexus, artifactory etc?

  • Bypass Credential dialog box of internet explorer

    - by m23
    My c# application opens the Internet explorer for different web URL/ domains. And I have all those credential information (username, password and domain name) stored in the database for each web application. Now how I can authenticate automatically without entering credential in “Network Credential” dialog box using code or bypass that dialog box? In other words I need to store those credential on system so no need to enter. I am using c#

  • Quality of TFS 2008 merged code

    - by paologios
    Does the quality of code merged by TFS 2008 depend on the used programming language? I know merging in Java / Subversion, and merging a branch to its trunk usually does not create much conflicts. Now in my company, we use VB.NET. When I merge two files TFS does not always get code blocks right, e.g. does not find the right If..then / end if lines. To give you an example, I mean: File 2 is created as a branch of File 1. Both files were changed later, now I'm going to merge those files and am recieving conficts: The marked end-if lines (1) are detected as corresponding, meaning the added event handler Button1_Click is being deleted. Now I wonder if this behavior is by language (C# vs. VB.NET) or are other source control solutions just better than TFS? (And I really liked TFS up to now :) ) File 1: Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load If Not Page.IsPostBack Then Label1.Text = "Hello" Label2.Text = "World" End If End Sub Protected Sub Button2_Click(ByVal sender, ByVal e as System.EventArgs) Handles Button2.Click // .... If Page.IsValid Then Label3.Text = "Hello Button 2" End If // .... End Sub File 2 (Branch of File 1): Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load If Not Page.IsPostBack Then fillTableFromDatabase() End If // (1) End Sub Protected Sub Button1_Click(ByVal sender, ByVal e as System.EventArgs) Handles Button1.Click // do something here End Sub Protected Sub Button2_Click(ByVal sender, ByVal e as System.EventArgs) Handles Button2.Click // .... If Page.IsValid Then End If // (1) // .... End Sub

  • iPhone: How to Determine Average Light/Dark of an Area of an UIImage

    - by TechZen
    I need to place labels with a transparent background over a variable-content UIImage. Readability will vary significantly depending on the relationship between the color of the label's text and the color/luminosity of the area of the image displayed under the label. Since the image will be constantly changing, the color of the label's text needs to change in sync. I have found several techniques for determining the color, perceived luminosity etc of a single pixel. However, I need to rather quickly (while a view loads) determine the rough perceived color/luminosity of an area of the UIImage under the frame of the UILabel. I presume I will also need to measure the alpha because the same color/luminosity looks different at different alpha values. Is there a way to calculate such a value for an area? Will I be reduced to simply summing pixels? If it comes to that, is there an algorithm to accomplish this? I've thought of two possible approaches: Perform some "folding" operations i.e. combining pixels from one half of the area to the other half. Then repeat until I get a single value. Would this be practical? How would you logically combine pixels to average their perceived color/luminosity? Sample a statistically significant number of pixels in the area and then combine them (somehow) to get a rough measure. I think this problem comes up a lot these days with people being so found of customizing backgrounds. Seems like something that would be worth my time to bang out a category or class to handle this and then share it around.

  • Trying to speed up a SQLITE UNION QUERY

    - by user142683
    I have the below SQLITE code SELECT x.t, CASE WHEN S.Status='A' AND M.Nomorebets=0 THEN S.PriceText ELSE '-' END AS Show_Price FROM sb_Market M LEFT OUTER JOIN (select 2010 t union select 2020 t union select 2030 t union select 2040 t union select 2050 t union select 2060 t union select 2070 t ) as x LEFT OUTER JOIN sb_Selection S ON S.MeetingId=M.MeetingId AND S.EventId=M.EventId AND S.MarketId=M.MarketId AND x.t=S.team WHERE M.meetingid=8051 AND M.eventid=3 AND M.Name='Correct Score' With the current interface restrictions, I have to use the above code to ensure that if one selection is missing, that a '-' appears. Some feed would be something like the following SelectionId Name Team Status PriceText =================================== 1 Barney 2010 A 10 2 Jim 2020 A 5 3 Matt 2030 A 6 4 John 2040 A 8 5 Paul 2050 A 15/2 6 Frank 2060 S 10/11 7 Tom 2070 A 15 Is using the above SQL code the quickest & efficient?? Please advise of anything that could help. Messages with updates would be preferable.

  • Pretty Printer for T-SQL?

    - by Paul
    I'm looking for a good T-SQL Pretty Printer so that all the code looks consistant between developers in our project. Preferably a free/open source one, but paid for isn't out of the realms of possibility as long as it's reasonably priced. Are there any particular industry leaders? I'm not that fussed about what particular standard it uses, but the more configurable the better. That way we can have little style wars among the developers and have a bit of fun to boot. ;-) I suppose I should add that Visual Studio and Management Studio integration would be considered favourably.

  • What port does OpenLink ODBC Driver use?

    - by user36737
    I use Avaya Reporting Services and OpenLink ODBC Drivers for db connection. I know that it uses port 5000 for handshaking but after that I believe it uses an random port for communication. I want to deploy my application and it will communicate with the client's system in their datacenter. They are asking what ports should they open on their firewalls. I can't obviously give them a range above 50,000 that I know OpenLink ODBC Drivers use. Can someone tell me what port should I tell my client to open?

  • FULL global search on Palm Pre [closed]

    - by JoelFan
    The so-called "global search" on Palm Pre (where you start typing characters into the launcher) only finds contacts of what you're searching is the title of the contact. It won't find it if it's inside the details of the contact. How do I really globally search the contacts?

  • LUKS-Encrypted Root Partition in Ubuntu 9.04

    - by Martindale
    I have a LUKS-encrypted root partition that I have installed Ubuntu 9.04 to. I have of course placed /boot on a separate ext2 partition, and my boot loader loads and functions correctly. However, I can't seem to get my initrd to load the LUKS-encrypted root using the appropriate /dev/mapper/ address. What hooks and scripts do I need to add to get this to function correctly, and what is the correct way to regenerate my initrd? I can CHROOT into this install, and everything works fine - but I just can't seem to get it to actually boot. Help!

  • Is it possible to rent a virtual instance of Windows/XP/Vista/7 in the cloud on pay as you go basis?

    - by Janusz
    I am a software developer and I need to test my software on different OS all the time. I am using free VPC images from IE6 compat kit from Microsoft but they have only limited options of Windows Versions (Win XP SP3 and some restricted version of Vista). I need a service where I could rent a Virtual OS in the cloud and connect via Remote Dektop. Use for couple of hours and then discard all the stuff I have been doing there. I tried using Amazon S3 but they only have Windows Server 2003 Anyone knows of such a service that would offer different XP/Vista/7 versions ?

  • Do I have to release modifications made to a GPL v2 CMS?

    - by John McCollum
    If we use a CMS that is covered by the GPL (v2), do we have to re-release the source code of the CMS if we make modifications to the core? The GPL v2 states: The GPL does not require you to release your modified version. You are free to make modifications and use them privately, without ever releasing them. This applies to organizations (including companies), too; an organization can make a modified version and use it internally without ever releasing it outside the organization. But if you release the modified version to the public in some way, the GPL requires you to make the modified source code available to the program's users, under the GPL. The grey area for me here is the part that states "if you release the modified version to the public in some way" - does displaying a website to the public count as "releasing it to the public"? What about if a custom plugin is written which integrates with the CMS - are we required to release the source? Does this count as a modification?

  • Drupal 6, Views 2: Is it possible to have a filter that only applies to registered users?

    - by dajoropo
    Hello, Is it possible to create a filter in a Drupal 6 View that is only applied for registered users? For one filter I need I'm using the user vote (With fivestar and votingapi) to know if they user already voted this node or not, and when the user is annonymous, is working as if all the votes from all the annonymous users where from the same. This is why I need to add this filter, but ignore it in case the user is annonymous. Thanks a lot in advance for the help!

  • Is this fix to "PostSharp complains about CA1800:DoNotCastUnnecessarily" the best one?

    - by cad
    This question is about "is" and "as" in casting and about CA1800 PostSharp rule. I want to know if the solution I thought is the best one possible or if it have any problem that I can't see. I have this code (named OriginaL Code and reduced to the minimum relevant). The function ValidateSubscriptionLicenceProducts try to validate a SubscriptionLicence (that could be of 3 types: Standard,Credit and TimeLimited ) by casting it and checking later some stuff (in //Do Whatever). PostSharp complains about CA1800:DoNotCastUnnecessarily. The reason is that I am casting two times the same object to the same type. This code in best case will cast 2 times (if it is a StandardLicence) and in worst case 4 times (If it is a TimeLimited Licence). I know is possible to invalidate rule (it was my first approach), as there is no big impact in performance here, but I am trying a best approach. //Version Original Code //Min 2 casts, max 4 casts //PostSharp Complains about CA1800:DoNotCastUnnecessarily private void ValidateSubscriptionLicenceProducts(SubscriptionLicence licence) { if (licence is StandardSubscriptionLicence) { // All products must have the same products purchased List<StandardSubscriptionLicenceProduct> standardProducts = ((StandardSubscriptionLicence)licence).SubscribedProducts; //Do whatever } else if (licence is CreditSubscriptionLicence) { // All products must have a valid Credit entitlement & Credit interval List<CreditSubscriptionLicenceProduct> creditProducts = ((CreditSubscriptionLicence)licence).SubscribedProducts; //Do whatever } else if (licence is TimeLimitedSubscriptionLicence) { // All products must have a valid Time entitlement // All products must have a valid Credit entitlement & Credit interval List<TimeLimitedSubscriptionLicenceProduct> creditProducts = ((TimeLimitedSubscriptionLicence)licence).SubscribedProducts; //Do whatever } else throw new InvalidSubscriptionLicenceException("Invalid Licence type"); //More code... } This is Improved1 version using "as". Do not complain about CA1800 but the problem is that it will cast always 3 times (if in the future we have 30 or 40 types of licences it could perform bad) //Version Improve 1 //Minimum 3 casts, maximum 3 casts private void ValidateSubscriptionLicenceProducts(SubscriptionLicence licence) { StandardSubscriptionLicence standardLicence = Slicence as StandardSubscriptionLicence; CreditSubscriptionLicence creditLicence = Clicence as CreditSubscriptionLicence; TimeLimitedSubscriptionLicence timeLicence = Tlicence as TimeLimitedSubscriptionLicence; if (Slicence == null) { // All products must have the same products purchased List<StandardSubscriptionLicenceProduct> standardProducts = Slicence.SubscribedProducts; //Do whatever } else if (Clicence == null) { // All products must have a valid Credit entitlement & Credit interval List<CreditSubscriptionLicenceProduct> creditProducts = Clicence.SubscribedProducts; //Do whatever } else if (Tlicence == null) { // All products must have a valid Time entitlement // All products must have a valid Credit entitlement & Credit interval List<TimeLimitedSubscriptionLicenceProduct> creditProducts = Tlicence.SubscribedProducts; //Do whatever } else throw new InvalidSubscriptionLicenceException("Invalid Licence type"); //More code... } But later I thought in a best one. This is the final version I am using. //Version Improve 2 // Min 1 cast, Max 3 Casts // Do not complain about CA1800:DoNotCastUnnecessarily private void ValidateSubscriptionLicenceProducts(SubscriptionLicence licence) { StandardSubscriptionLicence standardLicence = null; CreditSubscriptionLicence creditLicence = null; TimeLimitedSubscriptionLicence timeLicence = null; if (StandardSubscriptionLicence.TryParse(licence, out standardLicence)) { // All products must have the same products purchased List<StandardSubscriptionLicenceProduct> standardProducts = standardLicence.SubscribedProducts; //Do whatever } else if (CreditSubscriptionLicence.TryParse(licence, out creditLicence)) { // All products must have a valid Credit entitlement & Credit interval List<CreditSubscriptionLicenceProduct> creditProducts = creditLicence.SubscribedProducts; //Do whatever } else if (TimeLimitedSubscriptionLicence.TryParse(licence, out timeLicence)) { // All products must have a valid Time entitlement List<TimeLimitedSubscriptionLicenceProduct> timeProducts = timeLicence.SubscribedProducts; //Do whatever } else throw new InvalidSubscriptionLicenceException("Invalid Licence type"); //More code... } //Example of TryParse in CreditSubscriptionLicence public static bool TryParse(SubscriptionLicence baseLicence, out CreditSubscriptionLicence creditLicence) { creditLicence = baseLicence as CreditSubscriptionLicence; if (creditLicence != null) return true; else return false; } It requires a change in the classes StandardSubscriptionLicence, CreditSubscriptionLicence and TimeLimitedSubscriptionLicence to have a "tryparse" method (copied below in the code). This version I think it will cast as minimum only once and as maximum three. What do you think about improve 2? Is there a best way of doing it?

  • Autocomplete and User define keyboard

    - by Geetha
    Hi All, I am using asp:button to create a keyboard with A-Z and 0-9 for touch screen using Java script. This keyboard is linked with one textbox. If we click one button corresponding text will be displayed on the textbox. Its working fine. I have included the autocomplete feature to this textbox using jquery JQuery Autocomplete. Problem: The autocomplete is not working if i my user define keyboard. How to modify my key buttons as keyboard keys? Is it possible? Is there any other way to achieve this? Code: <asp:TextBox ID="txtSearch" runat="server"></asp:TextBox> <asp:Button ID="zero" runat="server" Text="0" CssClass="myclass" OnClientClick="return typeLetter(this);" TabIndex="20"/> function typeLetter(currentbutton) { if (previousActiveElement != null) { if (previousActiveElement == 'antSearchText'){ var position = document.getElementById('position').value; if (position == '') { alert('chk position'); } else { var existingString = document.getElementById(previousActiveElement).value; var beforeString = existingString.substring(0, position); var afterString = existingString.substring(position, existingString.length); document.getElementById(previousActiveElement).value = beforeString + currentbutton.value + afterString; setCaretPosition(document.getElementById(previousActiveElement), parseInt(position) + 1); setCaretPosition(document.getElementById(previousActiveElement), parseInt(position) + 1); } } } return false; }

  • ASP.NET FormsAuthentication Cookie Problem

    - by Niels Bosma
    We use FormAuthentication to manage logins and I have a case where a customer complains where he can login from one computer but to from another. I can see in my logs that his authentican is successfull but he gets bumped back to the login page. I can reproduce the symptons by disabling cookies so I asked the customer to test if cookies are enabled on http://www.tempesttech.com/cookies/cookietest1.asp, but this came out positive. What have I missed? Is there any antivirus/security software that can mess up (ASP.NET) cookies? The user is using IE7 and claims to have F-secure installed.

  • IE7 div floating bug

    - by Michael Frey
    I have the following <div id="border" style="width:100%; border:8px solid #FFF"> <div id="menu" style="width:250px; float:left;" > Some menu </div> <div id="content" style="padding-left:270px; width:520px;" > Main page content </div> </div> This gives me a left aligned menu and the content to the right of it, all surrounded by a border. On all browsers including IE8 it displays correctly. But on IE7 the content only starts below the menu, and leaves a big open space to the right of the menu. I have searched all kind of solutions and tried all kinds of combinations of right, left, none for float. clearing left right both. It always displays different on the browsers. Any help is appreciated. Michael

  • Repository pattern with lazying loading using POCO

    - by Simon G
    Hi, I'm in the process of starting a new project and creating the business objects and data access etc. I'm just using plain old clr objects rather than any orms. I've created two class libraries: 1) Business Objects - holds all my business objects, all this objects are light weight with only properties and business rules. 2) Repository - this is for all my data access. The majority of my objects will have child list in and my question is what is the best way to lazy load these values as I don't want to bring back unnecessary information if I dont need to. I've thought about when using the "get" on the child property to check if its "null" and if it is call my repository to get the child information. This has two problems from what I can see: 1) The object "knows" how to get itself I would rather no data access logic be held in the object. 2) This required both classes to reference each other which in visual studio throws a circular dependency error. Does anyone have any suggestions on how to overcome this issue or any recommendations on my projects layout and where it can be improved? Thanks
