We have successfully localized our windows-forms application. One form refuses to use the localized resources and is always shown with the embedded resources. I checked the following points:
The forms Localizable attribute is true
At runtime the UI-culture is set correctly
The satellite assembly is in the correct location
With SysInternals process explorer I verified that the process uses the satellite assembly
I opened the satellite assembly with IL-Spy and checked that it contains the translated resources
In the debugger I stepped into Microsofts ComponentResourceManager.ApplyResources Method for a button. It finds the text property but as the code is optimized I cannot see the really interesting things.
All other forms (different assemblies) appear with the correct language, only this one ...
I hope someone out there has a helpful idea.
Just stumbled upon the same issue but could solve it.
I just imported the localized resx files into the project. So the *.de.resx were part of the project, but the localized resources were not applied to all forms.
Referring to http://msdn.microsoft.com/library/y99d1cd3%28v=vs.110%29.aspx, the localized resource files should appear beneath the form (as a sub item).
So my solution was:
- go through all forms, change language from Default to German and back to Default.
- as a result, the *.de.resx files were listed as sub items of the forms
- then overwrite the just created *.de.resx files with the localized ones
Then it works for all forms. I have no idea, though, why it worked before for 3 forms out of 4.
What is the recommended way to add a new language to a Windows Forms application? Do I really need to click through all forms of my application for creating the empty resx files for the new language? Of course, I could edit the project file manually...

I am trying to localize a Xamarin Forms app. I followed all the steps included here: https://developer.xamarin.com/guides/xamarin-forms/localization/
However, in the Android Emulator, after changing the default language, the strings do not get displayed, they remain the default language. On the device the app doesn't even launch.
Steps taken so far:
1) tried breakpoint (BP) in the main launcher, it skipped the BP and entered the main page
2) tried BP on the Localize class, it doesn't reach it
3) tried BP on the Device.OS check, skips it.
The resource files in Visual Studio are the following:
AppResources.resx
AppResources.fr.resx
AppResources.es.resx
Anyone ever succeeded localizing a Xamarin Forms app before ? I need some assistance with this as Visual Studio does not raise any exception ...
UPDATE 1 :
The resource files in Visual Studio are the following:
AppResources.resx
AppResources.fr_FR.resx
AppResources.es_ES.resx
UPDATE 2:
After recent suggestions and modifications I have the following exception: Markup extension not found.
This is disturbing as the markup extension class is there.
Doesn't work in DEBUG mode (Android only)
If the translated strings are working in your RELEASE Android builds
but not while debugging, right-click on the Android Project and select
Options > Build > Android Build and ensure that the Fast assembly
deployment is NOT ticked. This option causes problems with loading
resources and should not be used if you are testing localized apps.
SOLVED:
The problem was in the declaration of the extension. In a PCL project, the following took place:
a) the TranslateExtension class is located in a subfolder named Pages
b) initial declaration was
xmlns:languages="clr-namespace:MyApp;assembly=MyApp"
c) the following declaration solved the problem:
xmlns:languages="clr-namespace:MyApp.Pages;assembly=MyApp"
along with language code naming conventions of the .resx files as mentioned above
2021 UPDATE
All the current answers are not valid anymore! You need to add resources. Right click your xamarin forms project (Not xamarin android or ios) => Go to project properties ==> Resources ==> Add Resource.
This will create a "Properties" Folder and a resources.resx file which you can delete if you want to.
Then follow the official microsoft documentation by creating a AppResources.resx and other language files (such as AppResources.ar.resx file for arabic). All these files MUST BE in the properties folder.
Then, in your XAML page, declare the namespace as:
xmlns:res="clr-namespace:YourProject.Properties"
Then simply use:
<Label Text="{x:Static res:AppResources.Address}" >
This will use the corresponding Language files depending on what language the device is using. If the language is not supported it will use the defulat file (AppResources.res)
FIUH!!! Wasted one hour to solve this!!!
The problem concerns Windows Forms.
I have no idea how to do it. I've tried following:
1) Add a Bitmap (CarControl.bmp) do the solution, then set BuildAction to Embedded Resource and add the ToolBoxBitmapAttribute like:
[ToolboxBitmap(typeof(CarControl),"CarControl")]
2) Going into Properties, then in Resources section I've added some images. Still doesn't work.
Can anybody help?
Naming is very important, otherwise it does not work.
[ToolboxBitmap(typeof(CarControl), "Resources.CarControl.png")]
Another important note:
If you open the solution of your CarControl you will always see the default gear icons for the controls of your actual build. But if you make a build and you add the controls of this (released) library to the Toolbox either by drag-and-dropping the dll or by Right click/Choose Items..., then the icon will appear.
If you did everything well, you will able to find the embedded resource in the compiled .dll when you open it with Reflector or other disassembler tool. The following example is from System.dll:
You should find a <DefaultNamespace of your project>.<Your resources folder>.CarControl.png here.
Been a while since I have localized a WinForm project.
Must be missing something really basic.
Made a Hello World Winform project (VS2008) to refresh myself.
(Production project is in VS2013)
All the documentation I find says that the form has a localizable property which needs to be set to true.
But I can't find it.
(I want to use localized resx files for each form in the production project to set the Text of controls. I can create the resx files but the forms are ignoring them.)
Could someone please point me in the right direction?
I can see that property in Properties window in VS2013:
and in VS2008:
I'm trying to figure a way to specify my C# application to use an embedded resource (icon) as my application icon (the one displayed for taskbar, task switch, etc).
Yet, as I already embedded my icon in a resource, I can manage to use it in my forms but not with my application yet.
In fact, if someone could first tell me where I'll be able to set this (which file) by hand instead of using the VS2010 GUI to specify it, that'd be a great start!
Yet, my icon is available in these 2 ways :
{{Namespace}}.Properties.Resources.c_name.ico and in {{Namespace}}.Refs.c_name.ico (as a property of a public static class inside a class library).
Windows is an unmanaged operating system that doesn't know beans about managed resources. The only icon it can display is one that's embedded as an unmanaged resource. You can see what unmanaged resources look like in Visual Studio. Use File + Open + File and pick a .NET exe file (won't work in Express). A .NET program should have three of them, an icon, a manifest that declares the program compatible with UAC and a Version resource. This is all done automatically by the compiler, note for example how the Version resource properties match the attributes you set in AssemblyInfo.cs
The IDE makes it simple to set the icon for a program, you use Project + Properties, Application tab, Icon setting. Just pick the same .ico file as you embedded as a managed resource. Forget about trying to share, it cannot work by design.
Simply set
Icon=yourNamespace.Properties.Resources.yourEmbeddedIconName;
System.Drawing.Icon.FromHandle(Properties.Resources.EliminarNota.GetHicon());
In my WinForms app, if I set an icon for my app and an icon for my Form, the icon appears twice in my executable. Is it possible to avoid this?
(This question has been asked before, here, but the answers didn't seem to solve the problem. vanmelle's answer appears to extract only one icon (e.g., 16x16), Sunlight's answer extracts only the 32x32, and lc's answer doesn't solve the problem: there is still a duplicated icon in the executable.)
If it's not possible to accomplish this task, why is this? What is it about using the same icon for an executable and a Form that's so hard in WinForms?
This is an inevitable consequence of running managed code on a completely unmanaged operating system. Windows Explorer only knows how to read unmanaged resources. You can see what they look like, use File + Open + File in Visual Studio and select your .exe. You'll typically see three resource groups listed there:
RT_MANIFEST, contains the manifest that tells Windows that your program is Vista aware
Version, contains the file version resource with values derived from your AssemblyInfo.cs file. You see its content when you use Properties + Details tab in Explorer. Note how the super important [AssemblyVersion] isn't visible in Vista and up
Icon, contains the icon you added.
This unmanaged resource data is separate from the managed resources you added. Managed resources are compiled into the assembly manifest. Unmanaged resources are stored in the .rsrc section of the image file. You can override the auto-generated version with the /win32res command line option. Which requires a .res file, a binary file that is generated from a .rc resource script by the rc.exe resource compiler. An age old Windows SDK tool.
This may change some day, the super-secret Midori project is a rumored to focus on a managed operating system. For now, we'll have to make do with the glue.
