Update a database from a .docx file - sql

Question

I have a HR web application which includes organization structure within workplaces.
The client is sending a .docx file with workplace name and its description. I need to make a C# application to get data from the .docx file and update some database tables with it.
I already tried .docx conversion to XML but I have no idea how to pick up data from that XML and insert it into the database.
Is there a easier way to update this database directly from a .docx file or what mechanics should I use to find data in the XML file.

Answer 1

Try this..
Below is the connection string to the database. You can modify it to suit yours
<connectionStrings>
<add name="conString" connectionString="Data Source=.\SQLEXPRESS;database=dbFiles; Integrated Security=true"/>
</connectionStrings >
To start with I have added a FileUpload control, a button and a Label to show messages
<asp:FileUpload ID="FileUpload1" runat="server" />
<asp:Button ID="btnUpload" runat="server" Text="Upload"
OnClick="btnUpload_Click" />
<br />
<asp:Label ID="lblMessage" runat="server" Text=""
Font-Names = "Arial"></asp:Label>
And here is the snippet which is called on the Upload Button Click event
C#
protected void btnUpload_Click(object sender, EventArgs e)
{
// Read the file and convert it to Byte Array
string filePath = FileUpload1.PostedFile.FileName;
string filename = Path.GetFileName(filePath);
string ext = Path.GetExtension(filename);
string contenttype = String.Empty;
//Set the contenttype based on File Extension
switch(ext)
{
case ".doc":
contenttype = "application/vnd.ms-word";
break;
case ".docx":
contenttype = "application/vnd.ms-word";
break;
case ".xls":
contenttype = "application/vnd.ms-excel";
break;
case ".xlsx":
contenttype = "application/vnd.ms-excel";
break;
case ".jpg":
contenttype = "image/jpg";
break;
case ".png":
contenttype = "image/png";
break;
case ".gif":
contenttype = "image/gif";
break;
case ".pdf":
contenttype = "application/pdf";
break;
}
if (contenttype != String.Empty)
{
Stream fs = FileUpload1.PostedFile.InputStream;
BinaryReader br = new BinaryReader(fs);
Byte[] bytes = br.ReadBytes((Int32)fs.Length);
//insert the file into database
string strQuery = "insert into tblFiles(Name, ContentType, Data)" +
" values (#Name, #ContentType, #Data)";
SqlCommand cmd = new SqlCommand(strQuery);
cmd.Parameters.Add("#Name", SqlDbType.VarChar).Value = filename;
cmd.Parameters.Add("#ContentType", SqlDbType.VarChar).Value
= contenttype;
cmd.Parameters.Add("#Data", SqlDbType.Binary).Value = bytes;
InsertUpdateData(cmd);
lblMessage.ForeColor = System.Drawing.Color.Green;
lblMessage.Text = "File Uploaded Successfully";
}
else
{
lblMessage.ForeColor = System.Drawing.Color.Red;
lblMessage.Text = "File format not recognised." +
" Upload Image/Word/PDF/Excel formats";
}
}
VB.Net
Protected Sub btnUpload_Click(ByVal sender As Object, ByVal e As EventArgs)
' Read the file and convert it to Byte Array
Dim filePath As String = FileUpload1.PostedFile.FileName
Dim filename As String = Path.GetFileName(filePath)
Dim ext As String = Path.GetExtension(filename)
Dim contenttype As String = String.Empty
'Set the contenttype based on File Extension
Select Case ext
Case ".doc"
contenttype = "application/vnd.ms-word"
Exit Select
Case ".docx"
contenttype = "application/vnd.ms-word"
Exit Select
Case ".xls"
contenttype = "application/vnd.ms-excel"
Exit Select
Case ".xlsx"
contenttype = "application/vnd.ms-excel"
Exit Select
Case ".jpg"
contenttype = "image/jpg"
Exit Select
Case ".png"
contenttype = "image/png"
Exit Select
Case ".gif"
contenttype = "image/gif"
Exit Select
Case ".pdf"
contenttype = "application/pdf"
Exit Select
End Select
If contenttype <> String.Empty Then
Dim fs As Stream = FileUpload1.PostedFile.InputStream
Dim br As New BinaryReader(fs)
Dim bytes As Byte() = br.ReadBytes(fs.Length)
'insert the file into database
Dim strQuery As String = "insert into tblFiles" _
& "(Name, ContentType, Data)" _
& " values (#Name, #ContentType, #Data)"
Dim cmd As New SqlCommand(strQuery)
cmd.Parameters.Add("#Name", SqlDbType.VarChar).Value = filename
cmd.Parameters.Add("#ContentType", SqlDbType.VarChar).Value _
= contenttype
cmd.Parameters.Add("#Data", SqlDbType.Binary).Value = bytes
InsertUpdateData(cmd)
lblMessage.ForeColor = System.Drawing.Color.Green
lblMessage.Text = "File Uploaded Successfully"
Else
lblMessage.ForeColor = System.Drawing.Color.Red
lblMessage.Text = "File format not recognised." _
& " Upload Image/Word/PDF/Excel formats"
End If
End Sub
The above code simply reads the uploaded File as Stream and then converts the Stream to Byte array using Binary Reader and then the finally the byte arrays is saved to the database InsertUpdateData method executes the query to save the data in database
The InsertUpdateData function is given below
C#
private Boolean InsertUpdateData(SqlCommand cmd)
{
String strConnString = System.Configuration.ConfigurationManager
.ConnectionStrings["conString"].ConnectionString;
SqlConnection con = new SqlConnection(strConnString);
cmd.CommandType = CommandType.Text;
cmd.Connection = con;
try
{
con.Open();
cmd.ExecuteNonQuery();
return true;
}
catch (Exception ex)
{
Response.Write(ex.Message);
return false;
}
finally
{
con.Close();
con.Dispose();
}
}
