The following happens when I change my operating system’s language:



pCell->TextGet(strCopy); // strCopy == "3.00"


The problem seems to happen inside void CExtGridCellVariant::TextSet when this line is invoked:

HRESULT hr = ::VariantChangeType( this, &varSrc, 0, vt );


varSrc is indeed 0.03, yet the text value set is "3.00"


Can someone please explain this behavior so I can prevent it from happening?

OLE VARIANT APIs require number strings formatted according the current locale settings. You probably should use 3,00 instead of 3.00. Alternatively, you can convert text to a number in your code and initialize text value using the double value.
