Thank you Mr. AdamSpeight2008 for you help.

Sorry for the post above I cannot edit it.

Thank you for your response. I tried your code but still giving me an error

In this line of code


Using fs As New FileStream((imgPath), IO.FileMode.Open)

The process cannot access the file 'C:\Users\Niña\Pictures\tweety.jpg' because it is being used by another process.

Thank you for your response. I tried your code but still giving me the same error as what I have.

I debugged it already, It uploads the picture successfully but in the end, it is giving me an error

"parameter not valid"

The error occurs after I debugged all the lines.

so where exactly you wanna put toast?
