  • Is it possible to use theme colors in Windows Forms apps?

    - by Yadyn
    I normally make use of System Colors whenever possible when designing Windows Forms applications just so that it'll fit in with the user's preferences. But is it possible to use Theme Colors? I realize that this limits you in several ways (must be running Windows that supports it and has the Themes service running), so I would certainly like it if it could fall back on some other default, but since I'm fairly sure 99% of my users will have it available, I'd like to make use of it if possible. Specifically, for newer Windows versions (Vista and 7), things like hyperlinks have a softer more pastel-ish blue. The old System Colors do not define anything for links and the like, and in general are much more limited (coming from the 95 days) in choices and variety. Though WPF probably has better support, I'm not at liberty to use it. If some third party utility, assembly, or the like is necessary, it would also need to be free to use. I don't need anything that fancy, but in a perfect world I would be able to do something like this: linkLabel1.LinkColor = System.Drawing.ThemeColors.Hyperlink; Am I stuck just using the default Blue (0,0,255) and having them look out of place in Vista and above? I'll even settle for ugly p/invoke interop methods if need be...

  • Naming lossless more appropriate

    - by LarsOn
    Starting just discussing the naming first ignoring tech details, lossless is a negative and double negative word for one good reason should get named more appropriate: Lossless also matches nothing. When naming like all intact or likewise matches something in a manner more physical like sounds are. Then more technically stated that a copy might contain more information than the original. Does method as such have a name, if so what do I refer to, can we name it if you please or just discuss related handling.

  • JSF:Resourcebundle Problem with Internationalization

    - by Sven
    I implemented internationalization like in that tutorial! When I change the language in my app. It works. But only until the next request happens. Then language settings are reset to my standard language -.- What am I missing here: LanguageBean.java @ManagedBean(name="language") @SessionScoped public class LanguageBean implements Serializable{ private static final long serialVersionUID = 1L; private String localeCode; private static Map<String,Object> countries; static{ countries = new LinkedHashMap<String,Object>(); countries.put("Deutsch", Locale.GERMAN); //label, value countries.put("English", Locale.ENGLISH); } public Map<String, Object> getCountriesInMap() { return countries; } public String getLocaleCode() { return localeCode; } public void setLocaleCode(String localeCode) { this.localeCode = localeCode; } //value change event listener public void countryLocaleCodeChanged(ValueChangeEvent e){ String newLocaleValue = e.getNewValue().toString(); //loop country map to compare the locale code for (Map.Entry<String, Object> entry : countries.entrySet()) { if(entry.getValue().toString().equals(newLocaleValue)){ FacesContext.getCurrentInstance() .getViewRoot().setLocale((Locale)entry.getValue()); } } } } my facelets template: <h:selectOneMenu value="#{language.localeCode}" onchange="submit()" valueChangeListener="#{language.countryLocaleCodeChanged}"> <f:selectItems value="#{language.countriesInMap}" /> </h:selectOneMenu> faces-config: <application> <locale-config> <default-locale>de</default-locale> </locale-config> <resource-bundle> <base-name>org.dhbw.stg.wwi2008c.mopro.ui.text</base-name> <var>msg</var> </resource-bundle> </application>

  • Custom Membership in ASP.NET MVC 2

    - by Interfector
    Hello, I'm trying to make my Custom Membership starting from ASP.NET's. I have a users table created by me which has as Primary Key a Guid UserId, exactly the sames as ASP.NET's default user and membership table. I have all the Foreign Key relationships built. However, I cannot insert the user into my custom users table. The data gets inserted correctly into the default ASP.NET's tables. I have tried the following scenarios: First version Receive the user model from POST call the CreateUser method of the Membership.class (stuff gets inserted) without modifying the user object, I try to insert it using EF's AddObject I receive the following error: "Cannot insert the value NULL into column 'LoweredUserName', table 'asp.dbo.aspnet_Users'; column does not allow nulls. INSERT fails.\r\nThe statement has been terminated."} System.Exception {System.Data.SqlClient.SqlException The error actually makes sense as EF's AddObject doesn't know how to create the LoweredUserName value, and I don't want to do it, this is ASP.NET's job. Second version Receive the user model from POST call the CreateUser method of the Membership.class (stuff gets inserted) Get the Guid of the freshly inserted system user get the ASP.NET's User object and overwrite that of user.User get the ASP.NET's Membership object and overwrite that of user.Membership (remember the FKs) try again EF's AddObject new error {"The relationship between the two objects cannot be defined because they are attached to different ObjectContext objects."} System.Exception {System.InvalidOperationException} Don't know what this is, but it certenly doesn't make any sense for me. After some googleing I think that it has something to do with the context, but as I'm a beginner I don't know how to fix it. Any ideeas on how to accomplish this task are more than welcomed, especially if they follow some good practices. Thx

  • Rails deployment strategies with Bundler and JRuby

    - by brad
    I have a jruby rails app and I've just started using bundler for gem dependency management. I'm interested in hearing peoples' opinions on deployment strategies. The docs say that bundle package will package your gems locally so you don't have to fetch them on the server (and I believe warbler does this by default), but I personally think (for us) this is not the way to go as our deployed code (in our case a WAR file) becomes much larger. My preference would be to mimic our MVN setup which fetches all dependencies directly on the server AFTER the code has been copied there. Here's what I'm thinking, all comments are appreciated: Step1: Build war file, copy to server Step2: Unpack war on server, fetch java dependencies with mvn Step3: use Bundler to fetch Gem deps (Where should these be placed??) * Step 3 is the step I'm a bit unclear on. Do I run bundle install with a particular target in mind?? Step4: Restart Tomcat Again my reasoning here is that I'd like to keep the dependencies separate from the code at deploy time. I'd also like to place all gem dependencies in the app itself so they are contained, rather than installing them in the app user's home directory (as, again, I believe is the default for Bundler)

  • Unusual request URL in ASP.NET health monitoring event

    - by Troy Hunt
    I’m seeing a rather strange occurrence in the request information section of an ASP.NET health monitoring email I hope someone can shed some light on. This is a publicly facing website which runs on infrastructure at an Indian hosting provider. Health monitoring is notifying us of server errors via automated email but every now and then the requested URL appears as a totally different website. For example: Request information: Request URL: http://www.baidu.com/Default.aspx Request path: /Default.aspx User host address: 221.13.128.175 User: Is authenticated: False Authentication Type: Thread account name: NT AUTHORITY\NETWORK SERVICE Obviously the site in question is not Baidu and obviously this attribute is not the referrer either; the “Request URL” value is the path which has generated the error. The IP address is located in Beijing (coincidental given the Baidu address?) and in this instance it looks like the SQL server backend was not accessible (I haven't included the entire error message for security's sake). What would cause the request URL attribute to be arbitrarily changed to that of another site? I’ve never seen this occur in a health monitoring event before. Thanks!

  • Character Encoding: â??

    - by akaphenom
    I am trying to piece together the mysterious string of characters â?? I am seeing quite a bit of in our database - I am fairly sure this is a result of conversion between character encodings, but I am not completely positive. The users are able to enter text (or cut and paste) into a Ext-Js rich text editor. The data is posted to a severlet which persists it to the database, and when I view it in the database i see those strange characters... is there any way to decode these back to their original meaning, if I was able to discover the correct encoding - or is there a loss of bits or bytes that has occured through the conversion process? Users are cutting and pasting from multiple versions of MS Word and PDF. Does the encoding follow where the user copied from? Thank you website is UTF-8 We are using ms sql server 2005; SELECT serverproperty('Collation') -- Server default collation. Latin1_General_CI_AS SELECT databasepropertyex('xxxx', 'Collation') -- Database default SQL_Latin1_General_CP1_CI_AS and the column: Column_name Type Computed Length Prec Scale Nullable TrimTrailingBlanks FixedLenNullInSource Collation text varchar no -1 yes no yes SQL_Latin1_General_CP1_CI_AS The non-Unicode equivalents of the nchar, nvarchar, and ntext data types in SQL Server 2000 are listed below. When Unicode data is inserted into one of these non-Unicode data type columns through a command string (otherwise known as a "language event"), SQL Server converts the data to the data type using the code page associated with the collation of the column. When a character cannot be represented on a code page, it is replaced by a question mark (?), indicating the data has been lost. Appearance of unexpected characters or question marks in your data indicates your data has been converted from Unicode to non-Unicode at some layer, and this conversion resulted in lost characters. So this may be the root cause of the problem... and not an easy one to solve on our end.

  • How can I turn a column name into a result value in SQL Server?

    - by Brennan
    I have a table which has essentially boolean values in a legacy database. The column names are stored as string values in another table so I need to match the column names of one table to a string value in another table. I know there has to be a way to do this directly with SQL in SQL Server but it is beyond me. My initial thought was to use PIVOT but it is not enabled by default and enabling it would likely be a difficult process with pushing that change to the Production database. I would prefer to use what is enabled by default. I am considering using COALESCE to translate the boolean value to the string that value that I need. This will be a manual process. I think I will also use a table variable to insert the results of the first query into that variable and use those results to do the second query. I still have the problem that the columns are on a single row so I wish I could easily pivot the values to put the column names in the result set as strings. But if I could easily do that I could easily write the query with a sub-select. Any tips are welcome.

  • Using IsolatedStorage on a IIS server

    - by JoeBilly
    I'am a bit confusing about the use of Isolated Storage on an IIS server. I understand the goal of Isolated Storage : provides a safe place to store data with no worry about how and where is this place. Since Isolated Storage has a by-user and by-assembly approach, I'am not to wild about using it on a IIS server where applications have almost their own identity. I haven't really seen the interest of impersonating a web application and almost never seen impersonated web applications myself but this is my point of view. Using Isolated Storage on a server mean : Using Isolated stores in \Documents and Settings\<user>\ Which mean \Documents and Settings\Default User\ when the application pool is owned by Local System or Network Services I guess Which also mean Write rights on this folder for Local System or Network Services Using of impersonation Regarding a web application (logic), these ideas are confusing me... Document and Settings ? Default User ? Enable impersonation just for storage ? No control about storage on server ? Uh ? And then I'am a front of a dilema : use System.IO.Packaging (with Isolated Storage inside) on web applications or find an alternative ? Am I wrong in my approach ? Did I miss something ? Any point of view is appreciated and an explanation about the Isolated Storage with IIS philosophy could be an anwser. Thanks !

  • Using embedded resources in Silverlight (4) - other cultures not being compiled

    - by Andrei Rinea
    I am having a bit of a hard time providing localized strings for the UI in a small Silverlight 4 application. Basically I've put a folder "Resources" and placed two resource files in it : Statuses.resx Statuses.ro.resx I do have an enum Statuses : public enum Statuses { None, Working } and a convertor : public class StatusToMessage : IValueConverter { public object Convert(object value, Type targetType, object parameter, CultureInfo culture) { if (!Enum.IsDefined(typeof(Status), value)) { throw new ArgumentOutOfRangeException("value"); } var x = Statuses.None; return Statuses.ResourceManager.GetString(((Status)value).ToString(), Thread.CurrentThread.CurrentUICulture); } public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture) { throw new NotImplementedException(); } } in the view I have a textblock : <TextBlock Grid.Column="3" Text="{Binding Status, Converter={StaticResource StatusToMessage}}" /> Upon view rendering the converter is called but no matter what the Thread.CurrentThread.CurrentUICulture is set it always returns the default culture value. Upon further inspection I took apart the XAP resulted file, taken the resulted DLL file to Reflector and inspected the embedded resources. It only contains the default resource!! Going back to the two resource files I am now inspecting their properties : Build action : Embedded Resource Copy to output directory : Do not copy Custom tool : ResXFileCodeGenerator Custom tool namespace : [empty] Both resource (.resx) files have these settings. The .Designer.cs resulted files are as follows : Statuses.Designer.cs : //------------------------------------------------------------------------------ // <auto-generated> // This code was generated by a tool. // Runtime Version:4.0.30319.1 // // Changes to this file may cause incorrect behavior and will be lost if // the code is regenerated. // </auto-generated> //------------------------------------------------------------------------------ namespace SilverlightApplication5.Resources { using System; /// <summary> /// A strongly-typed resource class, for looking up localized strings, etc. /// </summary> // This class was auto-generated by the StronglyTypedResourceBuilder // class via a tool like ResGen or Visual Studio. // To add or remove a member, edit your .ResX file then rerun ResGen // with the /str option, or rebuild your VS project. [global::System.CodeDom.Compiler.GeneratedCodeAttribute("System.Resources.Tools.StronglyTypedResourceBuilder", "4.0.0.0")] [global::System.Diagnostics.DebuggerNonUserCodeAttribute()] [global::System.Runtime.CompilerServices.CompilerGeneratedAttribute()] internal class Statuses { // ... yadda-yadda Statuses.ro.Designer.cs [empty] I've taken both files and put them in a console application and they behave as expected in it, not like in this silverlight application. What is wrong?

  • Problem Implementing StructureMap in VB.Net Conversion of SharpArchitecture

    - by Monkeeman69
    I work in a VB.Net environment and have recently been tasked with creating an MVC enviroment to use as a base to work from. I decided to convert the latest SharpArchitecture release (Q3 2009) into VB, which on the whole has gone fine after a bit of hair pulling. I came across a problem with Castle Windsor where my custom repository interface (lives in the core/domain project) that was reference in the constructor of my test controller was not getting injected with the concrete implementation (from the data project). I hit a brick wall with this so basically decided to switch out Castle Windsor for StructureMap. I think I have implemented this ok as everything compiles and runs and my controller ran ok when referencing a custom repository interface. It appears now that I have/or cannot now setup my generic interfaces up properly (I hope this makes sense so far as I am new to all this). When I use IRepository(Of T) (wanting it to be injected with a concrete implementation of Repository(Of Type)) in the controller constructor I am getting the following runtime error: "StructureMap Exception Code: 202 No Default Instance defined for PluginFamily SharpArch.Core.PersistenceSupport.IRepository`1[[DebtRemedy.Core.Page, DebtRemedy.Core, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null]], SharpArch.Core, Version=1.0.0.0, Culture=neutral, PublicKeyToken=b5f559ae0ac4e006" Here are my code excerpts that I am using (my project is called DebtRemedy).

  • Django - Override admin site's login form

    - by TrojanCentaur
    I'm currently trying to override the default form used in Django 1.4 when logging in to the admin site (my site uses an additional 'token' field required for users who opt in to Two Factor Authentication, and is mandatory for site staff). Django's default form does not support what I need. Currently, I've got a file in my templates/ directory called templates/admin/login.html, which seems to be correctly overriding the template used with the one I use throughout the rest of my site. The contents of the file are simply as below: # admin/login.html: {% extends "login.html" %} The actual login form is as below: # login.html: {% load url from future %}<!DOCTYPE html> <html> <head> <title>Please log in</title> </head> <body> <div id="loginform"> <form method="post" action="{% url 'id.views.auth' %}"> {% csrf_token %} <input type="hidden" name="next" value="{{ next }}" /> {{ form.username.label_tag }}<br/> {{ form.username }}<br/> {{ form.password.label_tag }}<br/> {{ form.password }}<br/> {{ form.token.label_tag }}<br/> {{ form.token }}<br/> <input type="submit" value="Log In" /> </form> </div> </body> </html> My issue is that the form provided works perfectly fine when accessed using my normal login URLs because I supply my own AuthenticationForm as the form to display, but through the Django Admin login route, Django likes to supply it's own form to this template and thus only the username and password fields render. Is there any way I can make this work, or is this something I am just better off 'hard coding' the HTML fields into the form for?

  • How to use Object.GetHashCode() on a type that overrides GetHashCode()

    - by Jimmy
    Hi, I have a class A that implements IEquatable<, using its fields (say, A.b and A.c) for implementing/overriding Equals() and overriding GetHashCode(), and everything works fine, 99% of the time. Class A is part of a hierarchy (class B, C) that all inherit from interface D; they can all be stored together in a dictionary Dictionary, thus it's convenient when they all carry their own default Equals()/GetHashCode(). However, while constructing A I sometime need to do some work to get the values for A.b and A.c; while that's happening, I want to store a reference to the instance that's being built. In that case, I don't want to use the default Equals()/GetHashCode() overrides provided by A. Thus, I was thinking of implementing a ReferenceEqualityComparer, that's meant to force the use of Object's Equals()/GetHashCode(): private class ReferenceEqualityComparer<T> : IEqualityComparer<T> { #region IEqualityComparer<T> Members public bool Equals(T x, T y) { return System.Object.ReferenceEquals(x, y); } public int GetHashCode(T obj) { // what goes here? I want to do something like System.Object.GetHashCode(obj); } #endregion } The question is, since A overrides Object.GetHashCode(), how can I (outside of A) call Object.GetHashCode() for an instance of A? One way of course would be for A to not implement IEquatable< and always supply an IEqualityComparer< to any dictionary that I create, but I'm hoping for a different answer. Thanks

  • How to add WCF templates to Visual Studio Express?

    - by Mike Kantor
    I am working through the book Learning WCF by Michele Bustamante, and trying to do it using Visual Studio C# Express 2008. The instructions say to use WCF project and item templates, which are not included with VS C# Express. There are templates for these types included with Visual Studio Web Developer Express, and I've tried to copy them over into the right directories for VS C# Express to find, but the IDE doesn't find them. Is there some registration process? Or config file somewhere?

  • How are integers casted to bytes in Java?

    - by helixed
    I know Java doesn't allow unsigned types, so I was wondering how it casts an integer to a byte. Say I have an integer a with a value of 255 and I cast the integer to a byte. Is the value represented in the byte 11111111? In other words, is the value treated more as a signed 8 bit integer, or does it just directly copy the last 8 bits of the integer? Thanks, helixed

I had a problem with /usr/lib/libtdsodbc.so which is empty in default debian package free-tds dev, but i solved it with remove broken package and installation from sources. Will appreciate any thought! Thanks & Regards Note: I'm albe to connect using the same steps on mac 10.5

  • How to use prettify with blogger/blogspot?

    - by billpg
    Hi everyone. I'm using blogger.com to host some texts on programming, and I'd like to use prettify (same as stackoverflow) to nicely colour the code samples. How do I install the prettify scripts into the blog domain? Would it be better (if indeed its possible) to link to a shared copy somewhere? I have webspace on a different domain. Would that help? Many thanks.

Any ideas how to get up and running?

  • Why MAMP sets to 600 MySQL file permission?

    - by SergioP
    I usually put MAMP MySQL /db/db-site-name folder under SVN. When MAMP starts, it gives the drw------- (600) permission to all the files and dir in that folder. I have a problem because one of these folder is .svn one, that have to be drwxr-xr-x (755), otherwise I can't access to SVN working copy with my client. Can anyone help me to set MAMP properly?
