Need help in excel to vb.net

If e.g. i use vb.net codes to link to SQL server, is it possible to use Microsoft SQL server to update excel table? Then is it possible using html to get the excel table to vb.net application? Because i want to display the chart of the excel in vb.net.

Hm, e.g: voting poll. Using voting poll, i need to use SQL server to update the records of voting and is it possible like displaying the results as graph(using excel table to compile the table) and display in the vb.net form or so?

From there, is there any ways/codes to link to the vb.net application? hmm.. i hope you can help me to clarify my doubts.. cos i really need urgent help badly >.< ... Thanks..

*please help*

Im not sure if you can use excel with ASP.NET. As for producing graphs, you can produce graphs within ASP.NET.
Check out the graphics and charting section here (http://aspnet.4guysfromrolla.com/1.x/)

Why do you even need Excel for that? There are some excellent .NET chart libraries like Zed Graph (http://zedgraph.org/wiki/index.php?title=Main_Page).

But if you need to export data to Excel (http://www.gemboxsoftware.com/LA/Import-Export-XLS-XLSX-CSV-HTML-.NET.htm), I recommend GemBox.Spreadsheet .NET excel component (http://www.gemboxsoftware.com/GBSpreadsheet.htm).

To export data to excel (http://www.e-iceblue.com/Knowledgebase/Spire.XLS/Demos/DataTable.html)and create excel chart (http://www.e-iceblue.com/Knowledgebase/Spire.XLS/Demos/Charts.html) just few line code , try to use an excel component (http://www.e-iceblue.com/Introduce/excel-for-net-introduce.html)named Spire.XLS.
