Convert image to Base64 string in VBA

[SpeeD]

Hi.

Im mapping some XML fields in a worksheet to be exported to a web page.
On of this fields is a image field and it only accepts images in a base64
string format.

how can o convert a "normal" image to a base64 string inside excel trough VBA?

thanks a Lot!!!

What file type is the source and the converted. Are you trying t
convert BIT mapped files to JPG or something similar. You can't conver
an image to 64 bit format by just changing the string you need
utility.

Excel VBA can't convert directly but can call other utilites that yo
have installed on your PC. Excel can convert a worksheet to either JP
or Bit mapped by savving as a picture but I don't think this is what yo
want

Hi joel.

For what i discovered today there some components that will do the trick.
Anyway, if anyone has some direct answer (code) to this please post it here!

P.S: it´s important that i only use common components (do not install
anything) because i have to distribute the Workbook...
