Hi Peter,

You can try wwIPstuff from http://west-wind.com/wwIpstuff.asp. It supports Base 64 encoding.

>I'm trying to send an email with a jpeg using smtp with MIME formatting. My understanding is that I need to encode the jpeg into Base64 format. I have tried the class base64c of the base64.prg from http://fox.wikis.com/wc.dll?Wiki~Base64~SoftwareEng. I have also tried to use the strconv function in VFP 8. I got different results from them.

>After I have encoded a jpeg using either way, the email received by the recipient is still the encoded file if the email address is a yahoo email address. I kind of expect the email should be decoded automatically.:-( I hope someone can help me on this.
