How can you view a PDF in a picture box

You could try....I don't think it will work, but confirmation is only a quick test project away.

Now, as to the Adobe object, here's how you do it.

Open up the Toolbox, if it isn't already open. Right click under the "General" tab, and click "Choose Items."

Click the second tab called "COM Components," and near the top you should see "Adobe PDF Reader." Check it and hit OK.

Now you can drag the object onto your form. Notice that it adds two references to your project: AcroPDFLib and AxAcroPDFLib. Note that I have Acrobat 8 and Reader 9 installed, so I may have slightly different components than you...

If you want to get rid of the toolbar and make it just the PDF, you can use the setShowToolbar method.

Here is demo code-

If openFileDialog1.ShowDialog() = DialogResult.OK Then
           If openFileDialog1.FileName.EndsWith(".pdf") = True Or openFileDialog1.FileName.EndsWith(".PDF") = True Or openFileDialog1.FileName.EndsWith(".Pdf") = True Then
               PictureBox1.Hide()
               PDFPictureBox.LoadFile(openFileDialog1.FileName)
               Panel1.AutoScrollMinSize = PDFPictureBox.Size()
               PDFPictureBox.Show()
           Else
               PDFPictureBox.Hide()
               PictureBox1.ImageLocation = openFileDialog1.FileName
               PictureBox1.Load()
               Panel1.AutoScrollMinSize = PictureBox1.Image.Size()
               PictureBox1.Show()
           End If
       End If
