Summary: Microsoft Office PerformancePoint Server 2007 has the ability to generate Excel and PowerPoint documents without the presence of Microsoft Office. 

Introduction

Using Microsoft Office PerformancePoint Server 2007 APIs to generate Excel and PowerPoint documents is interesting if:

·         You need to generate Excel and PowerPoint documents without the presence of Microsoft Office.  This would be important if you're building a server that needs to generate Excel and PowerPoint documents, and you want to avoid using Office Automation on the server.   Note: Microsoft does not currently recommend, and does not support, Automation of Microsoft Office applications from any unattended, non-interactive client application or component (including ASP, DCOM, and NT Services), because Office may exhibit unstable behavior and/or deadlock when run in this environment.  See details at http://support.microsoft.com/kb/257757.

·         You need to generate Excel and PowerPoint documents with a simplified API that does not require a comprehensive understanding of the Office (2007) Open XML File Formats.  See details at http://msdn2.microsoft.com/en-us/library/aa338205.aspx for more information on the Open XML File Formats.  Though the Office (2007) Open XML File Formats are not difficult to learn, certain limited scenarios may be reached more quickly by using the APIs found in Microsoft Office PerformancePoint Server 2007.

Technologies

Microsoft Office PerformancePoint Server 2007 APIs generate Excel and PowerPoint documents by natively generating xml, and using .NET Framework 3.0 to insert that xml into XPS based packages that then can be opened by Excel 2007 and PowerPoint 2007 clients as xlsx / pptx files.  See details on XPS at http://msdn2.microsoft.com/en-us/windowsvista/aa904982.aspx.

In order to use the Microsoft Office PerformancePoint Server 2007 APIs to generate Excel and PowerPoint documents, you need to reference the following PPS assemblies:

Creating a Simple Excel/PowerPoint Document

The following code creates a very simple Excel spreadsheet, and a similar looking PowerPoint presentation.  The complete code for this is at the end of this article.

            byte[] xlsx = NativeExport.ExportToOfficeDocument(ExportFormat.Excel, grid);

            byte[] pptx = NativeExport.ExportToOfficeDocument(ExportFormat.PowerPoint, grid);

            OutputBytesToTempDir("Document1.pptx", pptx);

        }

 

        private static void OutputBytesToTempDir(string outputFileName, byte[] bytes)

        {

            string outputFileFullPath = Path.Combine(Path.GetTempPath(), outputFileName);

            FileStream outputFileStream = new FileStream(outputFileFullPath, FileMode.Create);

            outputFileStream.Write(bytes, 0, bytes.GetLength(0));

            outputFileStream.Flush();

            outputFileStream.Close();

        }

    }

}

 

 

The above code creates an Excel spreadsheet and similar PowerPoint presentation that is very simple, devoid of formatting.  The currency values were specified as NumericRendering in the code (see above), so they resolve in Excel as numbers with numeric formatting to achieve the currency symbol, number group delimiters, and decimal characters.  The end result looks like this:

Adding Formatting to Excel/PowerPoint Documents

The following code applies fill color, font color, font sizing, and text alignment.  The complete code for this is at the end of this article.

 

            GridFormatInfo shaded = new GridFormatInfo();

            shaded.HorizontalAlignment = GridFormatInfo.HorizontalAlignments.Center;

            shaded.FontInfo = new GridFontInfo();

            shaded.FontInfo.FamilyName = "Tahoma";

            shaded.FontInfo.SizeInPoints = 10.0f;

            shaded.ForeColor = new GridColor(Color.Black);

            shaded.BackColor = new GridColor(Color.FromArgb(0, 235, 243, 255));

 

            TextRendering column3Text = new TextRendering();

            column3Text.Range = new CellRange();

            column3Text.Range.Format = shaded;

            column3Text.Range.Coordinates = "5,3,5,3";

            column3Text.Range.Text = "2007";

            elements.Add(column3Text);

 

 

The following code applies cell merging and borders.  The complete code for this is at the end of this article.

 

            CellRange[] ranges = new CellRange[3];

 

            ranges[0] = new CellRange();

            ranges[0].Format = new GridFormatInfo();

            ranges[0].Format.HorizontalAlignment = GridFormatInfo.HorizontalAlignments.Center;

            ranges[0].Format.FontInfo = new GridFontInfo();

            ranges[0].Format.FontInfo.FamilyName = "Arial";

            ranges[0].Format.FontInfo.SizeInPoints = 14.0f;

            ranges[0].Format.FontInfo.Bold = Trinary.True;

            ranges[0].Format.FontInfo.Italic = Trinary.True;

            ranges[0].Format.ForeColor = new GridColor(Color.Blue);

            ranges[0].Format.BackColor = new GridColor(Color.White);

            ranges[0].Coordinates = "3,2,3,5";

            ranges[0].IsMerged = true;

            ranges[0].Text = "ABC Company";

 

            ranges[1] = new CellRange();

            ranges[1].Format = new GridFormatInfo();

            ranges[1].Format.HorizontalAlignment = GridFormatInfo.HorizontalAlignments.Center;

            ranges[1].Format.FontInfo = new GridFontInfo();

            ranges[1].Format.FontInfo.FamilyName = "Arial";

            ranges[1].Format.FontInfo.SizeInPoints = 12.0f;

            ranges[1].Format.FontInfo.Bold = Trinary.True;

            ranges[1].Format.FontInfo.Italic = Trinary.True;

            ranges[1].Format.ForeColor = new GridColor(Color.Blue);

            ranges[1].Format.BackColor = new GridColor(Color.White);

            ranges[1].Coordinates = "4,2,4,5";

            ranges[1].IsMerged = true;

            ranges[1].Text = "International Sales";

           

            ranges[2] = new CellRange();

            ranges[2].BorderColor = "FF9999FF";

            ranges[2].BorderLineStyle = "thin"; // Currently, only "thin" is supported

            ranges[2].Coordinates = "3,2,6,5";

 

 

After applying fill color, font color, font sizing, text alignment, cell merging, and borders, the Excel spreadsheet and PowerPoint presentation look like this:

Inserting Images into Excel/PowerPoint Documents

 

The following code demonstrates how to insert an image into an Excel spreadsheet or PowerPoint presentation.  The following code reads image bytes in from an external file, but you can provide the bytes for the image any way you see fit.  The complete code for this is at the end of this article.

 

                FileInfo imageFile = new FileInfo(@"c:\chart.bmp");

                FileStream imageFileStream = new FileStream(@"c:\chart.bmp", FileMode.Open);

                byte[] imageBytes = new byte[imageFile.Length];

                imageFileStream.Read(imageBytes, 0, Convert.ToInt32(imageFile.Length));

                imageFileStream.Position = 0;

                Image imageAnalysis = Image.FromStream(imageFileStream);

                imageFileStream.Close();

 

                ImageRendering imageRendering = new ImageRendering();

                imageRendering.Column = 1;

                imageRendering.Row = 3;

                imageRendering.ImageBytes = imageBytes;

                imageRendering.ImageHeight = imageAnalysis.Size.Height;

                imageRendering.ImageWidth = imageAnalysis.Size.Width;

                imageRendering.PaddedRowHeight = imageAnalysis.Size.Height;

                imageRendering.Range = new CellRange();

                imageRendering.Range.Coordinates = "3,1,3,1";

                imageRendering.Range.IsSpillOver = true;

                elements.Add(imageRendering);

 

 

This can be used to generate Excel spreadsheets and PowerPoint presentations that contain a mixture of text, numbers, and images:

Conclusion

You can use the above approach to generate Excel spreadsheets and PowerPoint presentations using Microsoft Office PerformancePoint Server 2007 APIs. Certain limited scenarios may be reached more quickly by using these APIs, but for complete access to all Excel and PowerPoint document structure, please see the Open XML File Formats at http://msdn2.microsoft.com/en-us/library/aa338205.aspx. 

Complete Code List

Instructions for use:

1.     Install the .NET 3.0 Framework if it isn't already installed.

2.     Open Visual Studio and create a new Console Project.

3.     Replace the contents of the Program.cs file with the following code listing.  You can copy and paste directly from this page.

4.     Add a references to your project for the following assemblies:

System.Drawing

Microsoft.PerformancePoint.Scorecards.Client

Microsoft.PerformancePoint.Scorecards.Common

 

5.     Execute the code.
