Mar 31, 2011I'm getting an "index out of bounds" exception and I can't figure out why. Unfortunately, my VS 2010 is in Spanish, so I can't say what the exact message says, but it's a System.IndexOutOfRangeException.
This is a table with a column holding Double values and a column with Date values. I have a form with two DateTimePicker controls, so the user can set a date range and they should see a number showing the total amount calculated between those two dates.
I did something like this:
Private Sub getData(ByRef total As Double)
Dim connection As OleDbConnection
connection = New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data

VS 2008 : OleDbDataReader Not Reading Only?
Sep 21, 2010I am building an app to read a customers .xls file in to a array list the array is the being reordered and im writing a file out the back end.its doing several lookups in the .xls file to see if relivant data is there and it writes a different file (9 different specs) depending what is in each line/column.Sound simple and I have the app working great however when I use a customers live data I get an ex.message = "Could not decrypt file" the file opens in excel witthout any password prompts however it does look like the sheet is write protected but all im doing in my app is reading the data.

View 1 RepliesFindng End Of File In OleDbDataReader Routine
Jun 18, 2010I am using the OleDbDataReader routine to examine and manipulate Access databases.I am trying to find a procedure for indicating when the end of file is reached.I am getting an error message once the end of file is reached and another record is attempted to be read.The.HasRows modifier does not work; that merely determines if the source database contains rows, not if there are any rows remaining.

View 2 RepliesOleDbDataReader From Excel Gives Blank Line
Apr 8, 2010I am creating an application which uses OleDb to connect to an Excel spreadsheet and read the data into DataTable. The problem that I am having is that some of the columns I am getting are coming up blank, I've managed to narrow down that this is because that the first few lines for that column are blank. As unfortunately this is valid in the context of the Excel spreadsheet as not all dates etc. are required to be filled in. I was wondering whether anyone knows of any way that I could go about ensuring that the columns are populated by the OleDbDataReader even if the first x number of rows have that column as blank.

OledbDataReader Doesn't Work With Union Query In Access DB?
Sep 21, 2011I have two tables say "Table1" and "Table2". I made a UNION query and saved it as "AllTimesFailure". It is worth mentioning, I am using Access DB. When I am trying to fetch the records from AllTimesFailure through oledbDataReader, it says "The Microsoft Jet database engine cannot find the input table or query 'AllTimesFailure'. Make sure it exists and that its name is spelled correctly.". I double checked query name and found correct but the problem still exists. when I run the same query as I pass through my command object, it works fine in Access query analyzer and fetches records normally.

Use OleDbDataReader To Execute Union Query In MS Access Database
May 6, 2010I'm new to VB.NET. I'm trying very hard to not go screaming back to VB6...... I have a Query stored in an Access2000 database called 'build_VNMON'. (Does that make it a Stored Procedure ?) It uses multiple tables and multiple Union Statements to arrive at the desired results. It may not need to be as convoluted as it is, but I inherited it, and it works. What I really need is to output one column of the build_VNMON result to a text file, so I'm trying to use an OleDbDataReader.
