I have done a google and see that many people have asked the question on how to export a Datagridview to a Excel (.xls) file. For some reason I cannot seem to get it to work (i have gotton the program to open an Excel and save it, all hidden in the background). I use a bit of the coding from this source code [URL] but modified it and incorporated it into my program. It connects an OLE Database connection with the excel sheet... but what i want to do is beable to alter the sheet in the datagridview and export it back to an excel sheet. I am not trying to sound pushy when i say this but... if you download the source file i am using you will get a really good idea of my situation..

I seen some threads about export to Excel, but I tried all of it and nothing worked.I need to export the data on a DataGridView to an Excel (97 if it's possible or 2003 if not) sheet, using VB2010.
View 10 RepliesI've google so many examples but none of them work. Well they do but they don't perform the way I need it to:
1) Check if excel file with specific file name exists in application.startup path
2) If doesn't exist, then take DataGridView contents (including header names) and write it to a new excel file
If exists, then take DataGridView contents and append to the existing excel file (excluding header names)Can someone for the love of VB.NET paste some code that can do this? I've been at it for 3 days with no sleep and nothing has worked so far I make the smallest changes to code I find online and the bloody thing doesn't work anymore. I don't know why it does that...I already have Imports.Microsoft.Office referenced to my project so I can create Excel Applications on my form.

Is this MS office versions issue??
