I have a problem while using CarlosAg.ExcelXmlWriter to create excel file. I have installed the web application on the server. The application will create excel file on my machine and machine A without any problem. However, it does not work on machine B. I mean, no excel file will be created but only a xml file will be created. below is the xml code header part:

Anyone has any ideas?

Thanks for the example. It was very helpful. This .dll is very good as is the reverse engineering tool. Sadly, my needs require that reports be formatted with graphics (logos, charts). Given that the tool doesn’t support this, there remains a large gap between retail products like SoftArtisans and Carlos’ contribution. It would be perfect if you could open a template and stream the XML (just do this now with XML Writer object). This would be beside the point of not having Excel on server, I know.

Great for just dumping data into Excel, a joy to be free of COM (and free of cost!!)…unless you then have to open the output with COM to format further. I think anyone who muddles into SpreadsheetML needs a hobby :)

Hi,

is it possible to insert image into WorksheetCell
using CarlosAg ExcelXmlWriter dll???

Or additionally to add it into generated document?
Without use of Excel automation, of course.

thanks a lot for any advice.

Hi, really needs your help with it.

I’m trying to use the CarlosAg ExcelXmlWriter dll (which helped me alot so far) to create a pivot table, but somehow I got stuck with it.

Does anyone got a simple example for using his dll to export a data table to a pivot table?

thanks,
Emily.

We currently have to use the COM approach as when the user runs the excel document we want to generate charts on the fly.

Is it possible to add macros and bind them to events using this method?

Sure, but the code above will probably serve as little more than a guide to creating the worksheet. The API is very flexible–I usually feed it an object graph rather than a dataset myself.

Thanks

Is there any way i could use this in reverse and read in values from an excel file. I’m using the following code to read in from an excel file but when i try and host the web site it dosn’t work. Here’s my code:
Excel.Application excelApp = new Excel.ApplicationClass();
Excel.Workbook newWorkbook = excelApp.Workbooks.Add(XlWBATemplate.xlWBATWorksheet);

string workbookPath = fuExcel.PostedFile.FileName;
Excel.Workbook excelWorkbook = excelApp.Workbooks.Open(workbookPath, 0, true, 5, “”, “”, true, Excel.XlPlatform.xlWindows, “”, false, false, 0, true, false, false);

Excel.Sheets excelSheets = excelWorkbook.Worksheets;

string currentSheet = “Contacts”;

Excel.Worksheet excelWorksheet = (Excel.Worksheet)excelSheets.get_Item(currentSheet);

int rows;
rows = excelWorksheet.UsedRange.Rows.Count;

Excel.Range excelCell = (Excel.Range)excelWorksheet.get_Range(”A1″, “CN” + rows);
object[,] cells = (object[,])excelCell.Value2;

Can i install excel on the server or is there some other way i can read in the values?

Any help would be greatly appreciated.

Thanks,

Adrian
