EDraw WebOffice Component provides some methods to upload the file to a web server.


[id(36), helpstring(”Initializes the HTTP connection.”)]
boolean HttpInit();

[id(37), helpstring(”Adds the post parameter.”)]
boolean HttpAddpostString([in] BSTR Name, [in] BSTR Value);

[id(38), helpstring(”Adds the post file.”)]
boolean HttpAddPostFile([in] BSTR LocalFilePath, [in] BSTR NewFileName);

[id(39), helpstring(”Executes the post action.”)]
boolean HttpPost([in] BSTR WebUrl,[in, optional] VARIANT WebUsername, [in, optional] VARIANT WebPassword);

You can use the follow steps to save the opened office document to a web server.

Sub SavetoServer()
OA1.HttpAddpostString “author”, “anyname”
OA1.HttpAddpostString “Data”, “2007-5-15″
OA1.HttpAddPostFile “”, “newfilename.doc”
OA1.HttpPost “http://localhost:1320/Samples/UploadAction.aspx“

‘Or you can call the Save method to upload the openned file to the server directly.For examples:
‘OA1.Save “http://localhost:1320/Samples/UploadAction.aspx?FileName=newname”
End Sub

Note: If the first parameter of “HttpAddPostFile” is blank, the method will upload the opened office file to server.

Then you need to write a ASP.NET Get page to receipt the file.

Review the follow examples:

using System;
using System.Collections;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.IO;
using System.Web;
using System.Web.SessionState;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Xml;
using System.Drawing.Imaging;
using System.Text.RegularExpressions;

public partial class UploadAction : System.Web.UI.Page
protected void Page_Load(object sender, EventArgs e)
if (Request.Params[”author”] == “anyname” && Request.Params[”Data”] == “2007-5-15″)
Response.Write(”We have receipted the right param from Office ActiveX Control.”);
if (Request.Files.Count == 0)
Response.Write(”There isn’t file to upload.”);
if (Request.Files[0].ContentLength == 0)
Response.Write(”Failed to receipt the data.\n\n”);
string fullFileName = Server.MapPath(Request.Files[0].FileName);
Response.Write(”Upload Successfully.”);
