I have a Command Prompt window open and select all the characters and copy
them to the clipboard (some are OEM graphics symbols).

I then read them from the clipboard:

str = CType(DataO.GetData(DataFormats.OemText, False), String)

and try to convert them to unicode:

Dim InEncoding As Encoding = Encoding.GetEncoding(437)

Dim OutEncoding As Encoding = Encoding.Unicode

Dim StrAsBytes As Byte() = InEncoding.GetBytes(str)

Dim OutEncodingBytes As Byte() = Encoding.Convert(InEncoding, OutEncoding,
StrAsBytes)

Dim OutEncodingChars As Char() = OutEncoding.GetChars(OutEncodingBytes)

textbox1.text= = New String(OutEncodingChars)

But they do not display correctly.

Can you see what is wrong?

I know a different approach that works so what I'm trying to do here is to
learn something I apparently do not understand now.

Thanks for any enlightment

Hi Frankie, maybe I'm missing some basic concept on the clipboard, but
assuming your operation of reading its content with DataFormats.OemText is
correct, I think you should already have the string you want stored in
"str" after the following instruction

>>str = CType(DataO.GetData(DataFormats.OemText, False), String)

and that is just based on the fact that the .Net Framework internally
already works with Unicode strings

Please let me know if that is not the case
Aldo

I show the string in a messagebox and the characters are wrong. I don't have
the example here but a the character that looks like a full block in the
Command window shows as a Greek letter in the messagebox. Similar thing
happed to other graphic characters.

Could the clipboard simply take the bytes from the command window and make
then 16-bit without any other conversion?

I do have a way that works but, I'd like to remove a misunderstanding that I
must have because I don't know why the below code does not work!

Thanks for the reply
