hi,

I have a situation where I need to save current active document opened with my project. e.g. When I open Word or Excel file and I will do some changes into the same document. Now I want to save the document.

for Excel

C#

Microsoft.Office.Interop.Excel.Application excelApp = new Microsoft.Office.Interop.Excel.ApplicationClass();

//This will gives you the Active work book name
//excelApp.Application.ActiveWorkbook.Name;

//This will save the original document...
excelApp.ActiveWorkbook.Save();

in above code I am not getting the exact active workbook so that I can save it properly. It is showing null active workbook.

Is there any other way to save already opened DOCX, ELSX & PPTX document using C#?

Thanks & Regards,
Balkrishna Raut

C#

// Create Excel app
Microsoft.Office.Interop.Excel.Application excelApp = new Microsoft.Office.Interop.Excel.Application();

// Open Excel file
excelApp.Workbooks.Open("c:\\test\\test.xlsx", Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing);

// Find the active sheet
Microsoft.Office.Interop.Excel.Worksheet sheet = excelApp.ActiveWorkbook.ActiveSheet;

// Get a range to modify
Microsoft.Office.Interop.Excel.Range range = sheet.get_Range("A1", Type.Missing);

// Set a value for this range
range.set_Value(Type.Missing, "test value");

// Close and save the file
excelApp.ActiveWorkbook.Close(true, Type.Missing, Type.Missing);

// Close Excel
excelApp.Quit();

Hi,

"DizZ" answered to your question, but I want to add something. Maybe it will be useful to you sometimes. ;)

Look for OpenXML SDK! Here is the download link: http://www.microsoft.com/downloads/details.aspx?FamilyId=C6E744E5-36E9-45F5-8D8C-331DF206E0D0[^]

With it you can do what ever you want with any office document (docx,xlsx, pptx) in "OOP" way.
Using it you don't .
Working with it life is so much easier then using Office (excel word) interoperability. :-D
