You have to display the number, HOW the systems wants to show the number.

If you have problems with it, can can also replace the "," with a string replace. Roll eyes | :rolleyes:

This is controle by the LOCALE.

I'm not certain that you can force sprintf to a certain representation ( . instead of , ) ?

Not until _sprintf_l() came along. That might not be an option for the OP, however.

If I understand you correctly, you want numbers formatted like 123,456.78 regardless of the locale. Is that correct?

But why would you want to do this for countries that format numbers differently?

Hi,
Thanks to One and all for trying to help me in this regard,,

As of now after copying the double to the string i.e., after sprintf statement Iam checking if string has , using strchr().. If i find a ,(comma) iam replacing it with a . (dot). But if can find some other alternative in which i can copy the value in the double variable as it is to a String..

Btw the double variable has value with .(dot)

So have you called the SetTime() method (with 0 for the time)?

There is a member variable for a status bar called m_nMinHeight;

If you have subclassed the status bar you can set it in the constructor;

Otherwise you can send the status bar a SB_SETMINHEIGHT message setting the WPARAM to the required height.

this does mean much, but is this ok for you :

std::string str(CT2A(mytchar));

i'm not sure that will work, but as i don't know either what and why you want to do that, i cannot help much.

Don't know where to start ?

Try to open the key with ::RegOpenKeyEx with the security access mask set to REG_QUERY_VALUE to avoid errors due to insufficient rights in case the user is not an administrator or priveliged user. If the call returns ERROR_SUCCESS the key is present and if you're interested in the value of the key you call ::RegQueryValueEx.
Close the opened key with a call to ::RegCloseKey.
