Excel Application Error when too many rows?


I have created several reports with Aspose Excel that have worked fine until recently. I have worked out that if there are too many records/rows in the output file, although the XLS saves ok, it crashes Excel when I attempt to open it. I have tried creating the designer file with Excel 2000 and Excel XP, and have replicated the problem on several other computers. Is this a know issue? Is it an issue with the eval version??


Dear Alex,

Thanks for your consideration.

Could you send me your designer file and the test code?

I have fixed this. I was setting cell styles within a loop on a cell. As soon as I put the cell style commands outside this loop, it worked. Thanks anyway.

Aspose.Excel is replaced by a more advanced version as Aspose.Cells. You can set the style and many other properties as demonstrated in the following sample code.

// Instantiating a Workbook object
Workbook workbook = new Workbook();

// Obtaining the reference of the first worksheet
Worksheet worksheet = workbook.Worksheets[0];

// Accessing the "A1" cell from the worksheet
Cell cell = worksheet.Cells["A1"];

// Adding some value to the "A1" cell
cell.PutValue("Hello Aspose!");

// Defining a Style object
Aspose.Cells.Style style;

// Get the style from A1 cell
style = cell.GetStyle();

// Setting the vertical alignment
style.VerticalAlignment = TextAlignmentType.Center;

// Setting the horizontal alignment
style.HorizontalAlignment = TextAlignmentType.Center;

// Setting the font color of the text
style.Font.Color = Color.Green;

// Setting to shrink according to the text contained in it
style.ShrinkToFit = true;

// Setting the bottom border color to red
style.Borders[BorderType.BottomBorder].Color = Color.Red;

// Setting the bottom border type to medium
style.Borders[BorderType.BottomBorder].LineStyle = CellBorderType.Medium;

// Applying the style to A1 cell

// Saving the Excel file
workbook.Save(dataDir + "book1.out.xls");
