How do I convert a double to binary

[panks_r]

I have to store a DateTime in the registry in binary key. I think i can use the DateTime.m_dt variable which a double to store the value of the datetime. But I don't know how to convert it to binary like in Managed where we have the BitConverter.GetBytes(double). I need this urgently.

Hi, you can use a union with a buffer of 8 bytes and your DateTime.m_dt variable, like in the following example: typedef union DateTimeConversionTag { char m_buffer[8]; double m_datetime; } DateTimeConversion; http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vclang/html/_pluslang_typedef_specifier.asp[^] http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vclang/html/_pluslang_unions.asp[^]
