VS 2008 - Loading XLS File To DataSet And Import In MySQL

I want to load an xls file to dataset, edit the data, and import them in mysql. My problem is that I can't load the file. It seems like it ignores the file completely.

Dim MyConn As OleDbConnection
Dim myPath As String = "C:TempManinLottery2009.xls"
MyConn = New OleDbConnection("provider=Microsoft.Jet.OLEDB.4.0; data source='" & myPath _

I have a Dataset Lets call it Dataset1. I have 1 table in this dataset created in designer called settings. I want to be able to declare the intial dataset in one form as a global variable and make a copy of it in another form. However I don't want to fill it until after I have made the copy except that it is not working.[code]The problem is the Dt returns the same amount of columns and the exact column names that I have in the settings datatable. When I do Dt.ReadXml("Myxmlfile") I don't get any rows populated yet the columns are in the xml file and in the dt copy of the datable.

I have modified many helpful sources to come up with the attached code. What I am trying to acomplish is I need to import a txt or csv file and export it to an mdb file and then eventually back again. Everything works fine with the attached code when ever the path of the txt/csv file is inserted into the code. However the problem I am having is that I do not always know where the enduser is going to place
the txt/csv file. When I run the app, I get the following error message, "Not a valid File Name".

What i want to have happen is when the user selects for instance 'RPG' from the combo box the items displayed in the listbox change to the contents of the rpg.txt file. After searching around for a few hours and no luck i tried this
Private Sub ComboBox1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ComboBox1.SelectedIndexChanged

I have a problem with the function below. If anybody knows of a simpler way to accomplish the same results,The problem that I have with this function is that sometimes, not always, it keeps the Excel process running and when this happens I can run the function again until I kill the Excel process manually.
Another problem with this function is that it is slow if the Excel sheet contains a lot of data.
And also I can't get this function to read all the sheets in the Excel workbook and put the contents of each sheet in a separate data table in my dataset.

I am trying to load an Excel 97 single tabbed spreadsheet into a SQL server table using the OleDbDataAdapter function. From all the documentation I have found, the first parameter should be "select * from [sheet1$]". This works fine for me only if the tab in the worksheet is named Sheet1. If I change what's in the [] brackets to the actual tab name, it also works fine.

I have read and googled a ton of xml documentation but haven't quite gotten an answer to what Im trying to do. I am trying to create an XSD document that generates explicit type definitions for fields in the dataset. I am then trying to create a sample XML document that validates against the XSD document.
This works fine inside of visual studio because I can read in the schema and the document and it validates BUT, the xml document created has no real reference to the XSD via xlmns or other method. If I want to use this xml data in say MS Excel and I try to import it doesn't know where the XSD is to validate against so it assumes it based on the values. Is there a way in my code to add the xlmns to both the XSD and XML if that is what is needed to solve this? [Code]
