Hi,

If you only want to view PDF file, then you can use a PDF viewer, check this free .net pdf viewer:

http://www.e-iceblue.com/Introduce/free-pdf-viewer-net.html

Refer to following article to view pdf file:

http://www.e-iceblue.com/Tutorials/Spire.PDFViewer/Program-Guide/Open-PDF-Document-with-C-VB.NET-via-PDF-Viewer.html

Code snippet:


private void toolStripButton1_Click(object sender, EventArgs e)   
{       
    string pdfDoc = @"D:\michelle\e-iceblue\Spire.Office.pdf";       
    if (File.Exists(pdfDoc))       
    {           
        this.pdfDocumentViewer1.LoadFromFile(pdfDoc);       
    }    
}

If you want to choose the file from a dialog box, then refer to below code snippet:


private void toolStripButton1_Click(object sender, EventArgs e)    
{    
    OpenFileDialog dialog = new OpenFileDialog();    
    dialog.Filter = "PDF document (*.pdf)|*.pdf";    
    DialogResult result = dialog.ShowDialog();    
    if (result == DialogResult.OK)    
    {    
        try    
        {    
            string pdfFile = dialog.FileName;    
            this.pdfDocumentViewer1.LoadFromFile(pdfFile);    
        }    
        catch (Exception exe)    
        {    
            MessageBox.Show(exe.Message, "Spire.PdfViewer Demo", MessageBoxButtons.OK, MessageBoxIcon.Error);    
        }    
    
    }    
    
}

Dipankar Biswas12y ago
you can use my pro...

store this path into database like this
upload path..

like this:

Private Sub btn_brs_mat_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btn_brs_mat.Click
OpenFileDialog1.ShowDialog()
file = OpenFileDialog1.FileNames
txt_up_math_qus.Text = file(0)

'ComboBox2.Text = System.IO.Path.GetFileName(OpenFileDialog1.FileName)

End Sub

Inserted code:

If Not conn.State = ConnectionState.Open Then
conn.Open()

End If
cmd.Connection = conn
cmd.CommandText = "insert into Qus_upload_tbl(Subject_1,Subject_2,Subject_3,Subject_4,Subject_5,Date_Time)" & _
" Values('" & Me.txt_up_math_qus.Text & "','" & Me.txt_up_Reasoning_qus.Text & "','" & Me.txt_up_english_qus.Text & "','" & Me.txt_up_banking_qus.Text & "','" & _
Me.txt_up_computer_qus.Text & "','" & Me.txt_date.Text & "') "

cmd.ExecuteNonQuery()

'refrash data
RefreshData()

'close
conn.Close()

Show: Code

Private Sub DataGridView1_CellContentClick(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DataGridView1.CellContentClick
Dim i As Integer

i = DataGridView1.CurrentRow.Index

'Me.AxAcroPDF1.src = DataGridView1.Item(0, i).Value

If Me.DataGridView1.CurrentCell.ColumnIndex = 1 Then
Me.AxAcroPDF1.src = DataGridView1.Item(1, i).Value
End If

If Me.DataGridView1.CurrentCell.ColumnIndex = 2 Then
Me.AxAcroPDF1.src = DataGridView1.Item(2, i).Value
End If

If Me.DataGridView1.CurrentCell.ColumnIndex = 3 Then
Me.AxAcroPDF1.src = DataGridView1.Item(3, i).Value
End If
If Me.DataGridView1.CurrentCell.ColumnIndex = 4 Then
Me.AxAcroPDF1.src = DataGridView1.Item(4, i).Value
End If
If Me.DataGridView1.CurrentCell.ColumnIndex = 5 Then
Me.AxAcroPDF1.src = DataGridView1.Item(5, i).Value
End If

End Sub
