VB Upload file Chinese OS - HTTP Post body Method- HELP !

Hi Guys,

Me trying to upload file using VB HTTP Post method. Can successfully upload the files when my client machine is English OS . However , the problem occurs when am trying to upload the files from Chinese OS. It seems that the file uploaded is getting corrupted and could not be opened in correct format. This is applicable for binary files. The text files could be uploaded successfully.
I have tried setting content-type, charset,codepage etc properties to assemble the body.

Can anyone help me ? Its urgent ....Hope to find some VB GURU in this group.HELP !

Thanks in advance,

Moved from the Codebank

Load the file into a byte array, not a string variable (strFile). If you want it as a Unicode string later you can convert it using StrConv().

tried...hard luck :-(
