That’s because you are probably using a browser that doesn’t support something that html2canvas needs. Check with F12, my guess is that it’s the promise construct that is not supported by IE10. Try with Chrome instead.
You can also add a polyfill like this https://polyfill.io/v2/docs/ to Default.html. I tried with IE10 and now it works. See the requirements at https://html2canvas.hertzen.com/documentation.
I don’t understand how use it, I have a test button with this code on Click
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
Sub(ByVal img As Image)
PictureBox1.Image = img
but do nothing, If I put a breakpoint on row PictureBox, the visual studio don’t break on it
