SetThreadLocale

I am developing an application that is available in multiple languages.

Currently we set the UI language for the application using an installer which means that you can run in German on any language OS. However there is one problem and that is with Microsoft dialogs and wizards. They seem to want to load the resources based on the current locale.

An example is: OS is English, Locale is France, and you install German application. This results in French resources being used for property sheets while German is used everywhere else.

There are two ways that I have found to stop this. One was to create a seperate DLL for each language. However the company I was hired to do localization work for seems to still be in afterthought mode and there is too much resistance for this. Not to mention if I had unlimited time to really do localization right there are many problems to fix.

The second way was to call SetThreadLocale(). This loads the wizards correctly, however I keep seeing that SetThreadLocale() is a bad function and should never be used. Is this true?

We already use our own version printf() to allow different non-standard tokens to be used in strings. So I also overwrote this so the use of formatting numbers, dates, and other localization settings is already preserved based on user locale.

I just wanted to make sure I would or wouldn't be making a huge mistake using SetThreadLocale because I didn't know all the reasons it has been blacklisted.

Thanks

Localization / Internationization is not a simple task. It will be more complex if your application is not UNICODE app & need to support asian languages (eg. Traditional/Simplified Chinese / Japanese / Korea).

Use SetThreadLocale() is fine if it solves your problem. But in my experience, it didn't.

MS Press has a good book for that but I cannot find the name.

There is a new book "Internationalization and Localization Using Microsoft .Net" which I havn't read.

You need to draw the image in your OnPaint handler, then it will be drawn whenever your form needs to refresh itself.

Also check that you are deleting all your GDI objects correctly. If your app runs out of them it can cause unusual display problems.

A good way to check for GDI leaks is watching the GDI object count in the Task Manager, finding them is another problem altogether.

Hi!
I am trying to run an .exe file in my C++ code.
Let me say,
I have do.exe program.
And another control_do.exe program that can run do.exe conditionally.
Any code suggestion that is generic, not VC++?
I am using Visual Studio 2005, but code is standard c++, but VC++.
Thanks!

Use shell Execute
for example this line below opens a browser connecting to the appropriate link passed to it where xyz is the name of the site
ShellExecute(NULL, NULL,"http://xyz.com", NULL, NULL,SW_NORMAL );

Vision is Always important and so is your ATTITUDE.

How do I do this:

typedef enum Something {

  FirstValue,
  SecondValue,
  ThirdValue,
  FourthValue,
  Etc

} Something;

int main( void )
{
  Something MyVar;

  MyVar = SecondValue;
  MyVar++;  // I get "binary '++' : 'enum Something' does not define this operator or a conversion to a type acceptable to the predefined operator" at this line
}

One possible solution is casting via numeric type such as integer.

Try

MyVar = (Something)(MyVar + 1);

This is dangerous behavior since MyVar+1 may not be in Something such as:

<br />
typedef enum Something {<br />
  FirstValue=0,<br />
  SecondValue=2,<br />
  ThirdValue=4,<br />
  FourthValue=6,<br />
  Etc<br />
} Something;<br />

You will have to overload operater ++ for your problem.

Should not do this.
If you must do this, you can replace "TYPEDEF" by "CLASS".
Then, overloading operator ++.

Reading INF file

pgibson00770022-Mar-06 9:42

22-Mar-06 9:42

I have a VC++ application where I need to read (and sometimes parse) the contents of various printer manufacturers INF files to populate a listbox to enable our users to select which printer to install. I am stuggling to find example code using the following setupapi calls

SetupGetLineByIndex
SetupGetStringField

I have tried using the Profile api's also, but some INF's are better than others and using GetPrivateProfileSection doesn't always work successfully and involves rather messing string handling.

Any help would be appreciated, many thanks in advance.

How do I implement a custom tag?

22-Mar-06 8:27

I'm not sure if this is the right forum for this question, but I apologize if this question should be asked in a different place?

I would like to create a application (windows MFC for now) that uses a custom tag that will exist in web pages and email applications (e.g. Outlook emails). Basically, the new tag will have URL in the format of mytag://www.somesite.com . When the user clicks on the link with the custom tag the application is triggered.

Also, I would like the handcursor to be different to show a custom icon when the mouse is above the custom link. Is this possible? How can I implement this or where can I find more information on how to implment this application?

any information will be greatly appreciated!

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
