How to upload an image with additional data?

[RBeaubien]

I need to upload images to a web site, along with additional information such as Title, etc...

I'm using the HttpUtils, and the application is crashing..

I am reading the file in, convert it to Base64, and doing a PostString.

Here is the code I am using to read the image in, and convert it to Base64.

   inStream = File.OpenInput(photoPath, cur.GetString("PhotoFilename"))

   Dim buff(inStream.BytesAvailable) As Byte
   
   inStream.ReadBytes(buff, 0, inStream.BytesAvailable)
   
   tempVal = su.EncodeBase64(buff)

however, as soon as that is complete, and it tries to execute the next line of code, the application gets an error "The application <name> (Process <name>) has stopped unexpectedly. Please try again".

Two questions...

1) Is that code correct for converting the file to Base64 string?

2) Is there a better way to upload a file with additional data?

Thanks!

Ok, figured out what I was doing wrong with the input stream.

Should have gotten the size of the file and not used the BytesAvailable as the two won't necessarily match.

Ok, I'm now having an issue with the Base64 Encoding.

I encode it with the String Utilities, send it to the web site, however, in VB.NET, when I try to decode it, it tells me that it has an invalid length for a Base64 char array.

Any ideas?

Can you post the exact error message?

Ok, got past that issue. Had to make the Base64 URL Safe...
