VB.NET & MS SPREADSHEET 10.0 / 11.0 COM COMPONENTS (OWC10.DLL OWC11.DLL)

[VB.NET@HOME]

Hiya all,

I'm a very new to VB.Net + need some help.

I'm writing a program that has a form and an MS Spreadsheet 11.0 activeX component on it (default name is axMicrosoft.Office.Interop.Owx11.AXSpreadsheet).

I want to be able to import + export data into this sheet.

So far: -

1) I can type data into the sheet in RUNTIME.

2) I can export the data to an Excel file using .Export in RUNTIME.

3) I can import data from a .CSV file, but only at DESIGN TIME using the "Commands and Options"-->Import-->DATATYPE=CSV URL=FILENAME.


Can someone please tell me how to: -

A) Import either a CSV or an Excel file into this component in RUNTIME

B) Export the sheet to a CSV file rather than an Excel file in RUNTIME


Cheers all,
Max

Welcome to the forum.

It would much easier to use Excel Automation do to what you need.

Hi, can you please explain how!

I originally wanted to embed an Excel Spread Sheet into my VB.NET app. but could only seem to place the Web objects spread sheet with it's limited capability.

You can use a DataGrid control to display data and save to a Excel workbook. Here is a simple example of how to automate Excel (Write to workbook).
