There are some methods and properties to operator the office control.

Code a solution using the control

The control is very customizable. You can change the color scheme of any of the control elements, as well as determine the border type and a custom caption. These can be set at run time or design time as needed.

1.        Create new documents

The component allows you to create new documents for any ActiveX document type that is registered on the system. A user can use the custom function that you provide to create new documents.

You can also open and edit Office documents that exist on a local drive. You can call the Open method directly and give the control a specific file to open.

3.        Open Web folder

You can also open and edit Office documents that exist on web folder. Open takes either a qualified file path or a URL to a file on a remote Web server. For example, the following code opens a web file.

5.        Save Documents

6.        Show Save File Dialog

7.        Save Web Folder

Note: In order to save and upload the opened file in the Edraw Viewer OCX For PowerPoint, you must write a method in your web server to receive the stream. （Please review the full sample codes in the install package）

ASP:

private void Save()

{

       Stream stream = Request.InputStream;

       StreamReader sr = new StreamReader(stream);

       string uploadString = sr.ReadToEnd();

       sr.Close();

       stream.Close();

       try

       {

              FileStream fs = new FileStream(@"c:\Test1\test.doc",

FileMode.OpenOrCreate ,FileAccess.Write,FileShare.None);  

              byte[] _fs = Request.ContentEncoding.GetBytes(uploadString);

              fs.Write(_fs,0,_fs.Length);

              fs.Flush();

              fs.Close();

       }

       catch(Exception ex)

       {

              Response.Write(ex.ToString());

       }

}            

ASP.NET:  (See  \install path\sample\ASP.NET)

protected void Page_Load(object sender, EventArgs e)

    {

          String Action = Request.QueryString[“Action”]     

        If(Action == “savefile”{ 

string fileName = Request.QueryString["FileName"];

              if (fileName == "") fileName = "temp.ppt";

              Stream stream = Request.InputStream;

              byte[] fileByte = new byte[stream.Length];

              stream.Position = 0;

              stream.Read(fileByte, 0, fileByte.Length);

              stream.Close();

              string strTempPath = "c:\\";

              string packageFilePath = strTempPath + fileName;

              using (FileStream fileStream = new FileStream(packageFilePath, FileMode.CreateNew))

              {

                 fileStream.Write(fileByte, 0, fileByte.Length);

                 fileStream.Flush();

                 fileStream.Close();

             }

}

    }             

PHP:  (See  \install path\sample\SaveFile.php)

<?php

/* PUT data comes in on the stdin stream */

$putdata = fopen("php://input", "r");

/* Open a file for writing */

$fp = fopen("test.ppt", "w");

/* Read the data 1 KB at a time

   and write to the file */

while ($data = fread($putdata, 1024))

  fwrite($fp, $data);

/* Close the streams */

fclose($fp);

fclose($putdata);

?>

8.        Close Document

9.        Print Out

10.    Get the toolbars’ state

11.    Show or hide the toolbars

You can open an office document without toolbars as follow:

If OA1.GetToolbarsIsShow = True Then

OA1.ShowToolbars False

Else

OA1.ShowToolbars True

End If

12.    Is Modified

It returns true when the document has been altered or needs save.

BOOL bDirty = OA1.IsDirty

13.    Upload and Download file

The ActiveX Control supports upload and download file with HTTP or FTP method. 

Download file with HTTP method: 

OA1.HttpDownloadFile “http://www.anydraw.com/demo/Samples.doc”

Download file with FTP method: 

OA1.FTPDownloadFile “http://www.anydraw.com/demo/Samples.doc, “c:\Samples.doc”, “”, “”

Upload file with HTTP method: 

OA1.HttpUploadFile “http://www.anydraw.com/demo/SaveFile.php”, “c:\Samples.doc”

Download file with HTTP method: 

OA1.HTTPDownloadFile “http://www.anydraw.com/demo/Samples.doc”, “c:\Samples.doc”

14.    Automating Office Document

The control also supports a property called GetIDispatch that allows you to obtain a reference to the IDispatch interface of the embedded object. From this interface you can automate the object to perform tasks, edit parts of the document, or gather information about what a user has added or removed. For example, if you have a Word document open, you can use code that resembles the following to add a line of text:

Dim oDoc As Word.Document

Set oDoc = OA1. GetIDispatch

oDoc.Content.Text = "This was added by Automation"

The ability to control the object while the object is embedded is very powerful.
