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_1Subject_2Subject_3Subject_4Subject_5Date_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 its a simple but are u know how to show data from database???? if you know.. then its simple..

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); } } }
