'System.NotSupportedException' in mscorlib.dll

Hi, i have this error

Code:

---

'System.NotSupportedException' in mscorlib.dll
The format of the specified path is not supported.

---

what's the problem?? i

The problem is that the format of the specified path is not supported. If only there was a way for us to know what code and data actually generated the exception then we might be able to work out the root cause. I know! You could tell us.

this is the code:

with debug i have problem at

Code:

---

pBox.Image.Save("_" + nomeFile, Jpeg)

---

i'm try to do a grayscale image converter function

Code:

---


        Try
            pBox.Image = bm
            pBox.Image.Save("_" & nomeFile, Jpeg)
        Catch ex As NotSupportedException
            Console.WriteLine(ex.Message)

        End Try

---

i'm trying to add text to image, in pbox i can see text added to image but on save function i have that exception..
looking on google someone says that the problem is with windows 7 , is possible?

No, is not possible!

PictureBox1.Image.Save("_" & nomeFile, System.Drawing.Imaging.ImageFormat.Jpeg)

... and that's assuming that nomeFile doesn't include any directory information which seems unlikely given the error you're getting. _C:\somepic.jpg is not supported, strangely enough.
