It can be easily integrated into applications written in languages that support ActiveX control such as Visual C++, Visual Basic, Delphi, C++ Builder and .Net languages. Support Office automating client to custom your application. Include abundant sample codes. You also get the full c++ source codes.  

Name: Edraw Viewer OCX For PowerPoint

Code a solution using the control

Note: The install package includes some sample codes written with visual c++ 6.0, visual basic, Delphi, c++ builder, C#, ASP.Net, php and so on.

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

2.        Open Local PowerPoint file

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 from an URL

You can also open and edit PowerPoint files 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.

OA1. OpenWebFile "http://www.officeocx.com/demo/sample.ppt"

4.        Show Open File Dialog

5.        Save Documents

6.        Show Save File Dialog

7.        Save to Web Server

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 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://stdin", "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);

?>

You can also write the stream receive method with other language in the server.

8.        Close Document

9.        Print Out

10.    Get the toolbars’ state

You can open an office document without toolbars as follow:

If OA1.GetToolbarsIsShow = True Then

OA1.ShowToolbars False

Else

OA1.ShowToolbars True

End If

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.    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.officeocx.com/demo/Samples.doc”

Download file with FTP method: 

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

Upload file with HTTP method: 

OA1.HttpUploadFile “http://www.officeocx.com/demo/SaveFile.aspx?Action=’save’&Name=’temp.ppt’”, “c:\Samples.doc”

Note: you must write a Stream receive method in the server. Review the above the sample codes.

Download file with HTTP method: 

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

13.    Play Slide Show in the same window

14.    Run Slide Show in full screen mode

15.    Switch to the edit view

16.    Switch to the Outline view

17.    Switch to the Master view

18.    Switch to the Sorter view

19.    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:

COleVariant vOpt(DISP_E_PARAMNOTFOUND, VT_ERROR);

m_pOA->CreateNew(); 

LPDISPATCH lpDisp;

lpDisp = m_pOA->GetIDispatch();

_Presentation oPres;

oPres.AttachDispatch(lpDisp);

_Application oApp = oPres.GetApplication();

Presentations oPresSet = oApp.GetPresentations();

Slides oSlides = oPres.GetSlides();

_Slide oSlide = oSlides.Add(1, 1);  //ppLayoutTitle = 1

Shapes oShapes = oSlide.GetShapes();

Shape oShape = oShapes.Item(COleVariant("Rectangle 2"));

TextFrame oTxtFrm = oShape.GetTextFrame();

TextRange oTxtRng = oTxtFrm.GetTextRange();

oTxtRng.SetText("Automating PowerPoint");

oShape = oShapes.Item(COleVariant("Rectangle 3"));

oTxtFrm = oShape.GetTextFrame();

oTxtRng = oTxtFrm.GetTextRange();

oTxtRng.SetText("To Create and View a SlideShow");

oSlide = oSlides.Add(2, 12); //ppLayoutBlank = 12

oShapes = oSlide.GetShapes();

oShape = oShapes.AddOLEObject(20, 20, 660, 500, "MSGraph.Chart",

                                  "", 0, "", 0, "", 0);

//Get the Chart object so that you can automate MSGraph

OLEFormat oOLEFmt = oShape.GetOLEFormat();

MSGraph::Chart oChart = oOLEFmt.GetObject();

MSGraph::Application oGraphApp = oChart.GetApplication();

//Modify the chart's datasheet

MSGraph::DataSheet oData = oGraphApp.GetDataSheet();

MSGraph::Range oCells = oData.GetCells();

MSGraph::Range oCell;

COleVariant vCell;

oCells.Delete(vOpt);

vCell = oCells.GetItem(COleVariant((short)1), COleVariant((short)2));

oCell.AttachDispatch(vCell.pdispVal);

oCell.SetValue(COleVariant("John"));

vCell = oCells.GetItem(COleVariant((short)2), COleVariant((short)2));

oCell.AttachDispatch(vCell.pdispVal);

oCell.SetValue(COleVariant((short)520));

vCell = oCells.GetItem(COleVariant((short)1), COleVariant((short)3));

oCell.AttachDispatch(vCell.pdispVal);

oCell.SetValue(COleVariant("Sue"));

vCell = oCells.GetItem(COleVariant((short)2), COleVariant((short)3));

oCell.AttachDispatch(vCell.pdispVal);

oCell.SetValue(COleVariant((short)660));

vCell = oCells.GetItem(COleVariant((short)1), COleVariant((short)4));

oCell.AttachDispatch(vCell.pdispVal);

oCell.SetValue(COleVariant("Bill"));

vCell = oCells.GetItem(COleVariant((short)2), COleVariant((short)4));

oCell.AttachDispatch(vCell.pdispVal);

oCell.SetValue(COleVariant((short)690));

oChart.SetChartType(5); //xlPie = 5

MSGraph::PlotArea oPlot = oChart.GetPlotArea();

MSGraph::Border oBrdr = oPlot.GetBorder();

oBrdr.SetLineStyle(COleVariant((long)-4142));//xlLineStyleNone = 4142

MSGraph::Legend oLegend = oChart.GetLegend();

oLegend.SetPosition((long)(-4107)); //xlLegendPositionBottom = -4107

oChart.SetHasTitle(TRUE);

MSGraph::ChartTitle oChartTtl = oChart.GetChartTitle();

oChartTtl.SetText("ACME Corporation");

//Save changes to the chart and close MSGraph

oGraphApp.Update();

oGraphApp.Quit();
