Re: Change Locale in .Net? - C# Discussion Boards

3-Jan-04 11:17

I know how to do this via Win32 API's, but curious about how to do it in
.net. Is there a way in the framework to change the system's locale? System, not a thread's locale (found this easily in msdn). Doing this for a tool to help automate testing.

Thanks,

Juan Miguel Venturello

Look at the CultureInfo class, not sure if u can change it though Unsure | :~

As far as I can tell, you can only use this class to change on a per thread basis, I need to change window's locale programatically (like when using the regional settings control panel applet, or the win32 API's)

Thanks leppie. Anyone else knows?

Set Thread.CurrentUICulture to the desired CultureInfo. If you have controls that have already been initialized, you'll have to re-initialize them (note, not necessarily reinstantiate them) with a ResourceManager to have the new culture's information read from the satellite assemblies. If Windows's regional settings specifies a different culture for the UI, this all happens by default using the selected language, if available. Otherwise, the ResourceManager resorts to the neutral resources language (the localized resources in the assembly that contains your code). You should use the assembly attribute, NeutralResourcesLanguageAttribute, to keep the ResourceManager from making unnecessary look-ups for satellite assemblies for the culture that is already included in your primary assembly.

Thanks heath but... I already know all this. Again, I need this application to change the system's locale. I know this will not change the locale of running processes, but will determine the locale of new ones. This is what I need - this little applet is for performing a repetitive testing operation we need to do in several locales. About which locale this applet runs in... I don't care! It is not even localized. The app I am using to test of course is.

I am currently calling a C++ DLL which does the correct calls Smile | :)

kludgy! (SystemParametersInfo with SPI_SETDEFAULTINPUTLANG)... kinda works but I want to know if there is something in the FCL to do this.

Thanks,

Juan Miguel Venturello

So, basically, same as so often, use API's because FCL does not offer everything you need...

I know the concept goes way beyond this, but sometimes the FCL just seems like another wrapper around the API's which, to do some things, you need to call directly. Good old API's, glad I learnt them. Same story as VB programmers wanting to do things, having to call API's and getting all confused because they have no idea what an API, handle, etc, is....

Sure the framework/clr offers a ton of interesting things and makes things much easier, but why only offer a subset of the functionability of the API, not all? (like in this case). To make it portable to other platforms???!? OMG | :OMG:

Whatever, thanks for taking time to reply.

It's supposed to be a wrapper. The ability to P/Invoke makes framework extensible, although not portable as you mentioned. I haven't checked yet, but I'm betting Mono does support P/Invoked calls, albeit in a different library. I'm not defending this design, just mentioning that Microsoft has been very clear about this. It's not another Java - similar concept, different implementation. The JVM takes care of all the OS-specific operations, but the CLR is meant only to manage the objects and provide interoperability services. It sure beats JNI! (Trust me, I know). I guess you could say that they really differ most on how they handle native calls and both have advantages and disadvantages in the way they handle them.

Also, sorry I didn't notice that you said "system locale" in your first post. I read the thread before I posted originally and guess it just completely slipped my mind.

ArrayList Madness

eggie53-Jan-04 10:02

while(sReader.ReadLine()!=".")
{
    retrMessage.Add(sReader.ReadLine());
}

sReader, my StreamReader reads a network stream from a POP3 server one line at a time and adds it to my array retrMessage[].

Well, at least... it DID. I changed retrMessage from a string[], to an ArrayList. And now for some reason, only every other line is stored into the ArrayList (it skips lines).

Um, I'm assuming that this is an arraylist problem, because the string[] was handling it fine.

Does anybody have some inside on what's going on, and how I can fix this?

Hint: When you do a ReadLine the stream advances.

Yes, it's the StreamReader (actually, any stream or reader), but it's not a problem. This is the behavior of any IO on every platform I'm familiar with. You read, the cursor advanced.

leppie3-Jan-04 11:06

3-Jan-04 11:06

No! It's a logical error!

Step 1: You read a line and check if it is not "."
Step 2: You read a line and add it to the arraylist.

So you have to ask yourself one question, what happened to the string in step 1 if it wasnt "."?

Could anyone point me to a multiline (text of an item can be displayed on multiple lines) listview Windows Forms control?

Thanks

Trying searching[^] first. There's a ton of examples of this on CP alone, besides what the link above provides. It's just an owner-drawn ListView which is trivial to do. You could also google for it.

Do you need a ListView or a ListBox? The samples that are available are vastly different, and owner-draw ListBox examples are far more plentiful because they provide managed support for owner drawing, where a ListView requires that you override a hell of a lot of Windows messages and handle many different notification messages.
