I'm migrating to vb.net 2008 from long experience of vb6. I managed to create an Excel Sheet as an object, write data and save. How though, do I load an already created Excel file? The following code does a save, but what do I need to load a file?
ExcelSheet.SaveAs("C:UsersKochanskiDocumentsVisual Studio 2008ProjectsExcel TricksTEST.XLS")
I have an app, it was working but when it was copied to another machine, an error occuied.

I do have interop.excel.dll at the same place with app.
I'm using Excel as a database backend to load into a datagridview.
This is how I connect and bind to the dgv:
vb.net Dim sFileName = filelocation & "checks.xls"
Dim connectionStringTemplate As String = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source={0};Extended Properties=""Excel 12.0 Xml;HDR=Yes;IMEX=1"""
[CODE]...
It connects and populates fine. I have a button for the user to "refresh" the datagridview. I cannot get it to correctly refill the dgv. I have tried setting the bindsource.datasource to Nothing along with the datagridview datasource, but I get an error that brings up the Visual Studio debugger with no real error message...
I was wondering if there is any way to load data from excel sheet into a datagridview in VB2008 dynamically. I have looked at few data connection codes but all of them involve the excel sheet and thw workbook name. Is there anyway that I enter the excel sheet name in a inputbox and the data from excel loads into datagridview without hardcoding the sheet name. I know data can be imported using the below code, here the programmer has to mention the excel workbook name, path and sheet name. [code]I am developing a program to perform some calculations and my data is in a number of excel workbooks and worksheets. I need to be able to bring the data from these excel sheets into the datagridview to perform calculations. So I was thinking if I could mention the excel sheet name in the GUI and then accordingly the data from that particular sheet would be loaded into the datagridview to perform calculations.

I am trying to make a MVP kinda system and I am trying to define and load an array, through the system. Then read it out and it should populate a ListView1 object.I know they are set correct, because the console tells me it's set ok.I know the sample would fill with the same item (a week to be exact) every time i add an item, but that's not the point.Also, is it possible to define the array without the index, i mean now i set it with (6) so it sets 6 blocks for strings, but I would like to be more flexible. Is there a way like in php for example
$item["firstname"]
$item["lastname"]

I'm having some more trouble with working with arrays. My assignment is to take an input file of 10 numbers and display the original array, the array reversed (1st element is last element, etc.), the average of the parallel elements (nth element of both arrays), the average of the original array, and the elements greater than the average. I know I need to load the file into an array. However, I can't seem to figure out how to reverse it, nor average the two even if I can get it reversed.

Why I've choosen this forum (VB.Net) instead of Reporting is this seems not a matter of reporting. When I load the report normally, it works fine. When I export the report to Excel, it works fine again. After that when I tried to open the report again, it gives the error : "Load Report Failed" . I've to restart my application for make it work fine again.I'm using a Crystal Report Viewer control to load the report.
