I am unable to load the dat into the data Grid. Here is where I keep getting stuck.
dgvOleDb1 = table.Select
dgvOleDb1.DataSource = DataGridViewEditMode.EditProgrammatically
dgvOleDb1.DataSource = ds.Tables(0)
I am confused; I am using VB2010, IBM.iSeries.DB2 on an as400 V5R4. I am trying to establish an OLEDB connection, and return the values from the selected table to a DataGridView. I had one of the admin's make me file named GARBAGE, in the Rprtaccess catalog. In the past, I have been able to connect via access and an ODBC connection. My project is too big for access, and the SQL middleware we have is clunky and not user friendly. This is a program that will generate the SQL statements, specifically the WHERE: clause and populate the datagrid with the selected criteria. In essence I am making a user friendly striped down program, that has variables that are manipulated by the end user, and the rest, referenced tables and libraries are coded.

I have a script that checks a version table from one mdb (server) and compares it to the same table in another mdb (user folder), if the version number is mismatched it needs to replace that file from the server, to the user folder. The problem is, how to get the OLEDB connection to the user folder since, the folder destination is
E:Configurator & UserName & Detail2004.mdb
How to set this up?
Here is my code:
Dim UserName As String = Environment.UserName.Substring(Environment.UserName.LastIndexOf("") + 1)
Dim connectionString2 As String = "Provider=Microsoft.Jet.OLEDB.4.0;" + "Data Source=C:Configurator" & UserName & "Detail2004.mdb"
Dim con2 As New Data.OleDb.OleDbConnection(connectionString2)
Dim cmd2 As Data.OleDb.OleDbCommand
I am trying to connect DSN from my VB 2008 project. When i try using myoledb.connectionstring="DSN=myDNSname" I get the following error message An OLEDB provider was not specified in the connectionstring.
View 1 Repliesi want to ask what is the difference between oledb connection and odbc connection. I have a case, my office used ncomputing then i have to developed an application using sqlserver 2000 and vb.net 2005, i used oledb connection. When i try to implement it in ncomputing, why user must has admin access level and dbo level in sql server, it seems trouble when all users are admin. But there's a rumor that when using odbc connection, we dont need to give admin access level for users.es.
View 1 RepliesI've been all over the help files and finally patched together a VB OleDb connection string for delimited text files:
Dim connection As String = "Provider=Microsoft.Jet.OLEDB.4.0;" & "Data Source=" & fName & ";" & "Extended Properties=""text;HDR=YES;FMT=Delimited"""
"fName" is passed in by an open file dialog.In every case (for all paths) it throws: 'C:1_2010NormalFileNormal.csv' (or where ever it is pointed) is not a valid path. Make sure that the path name is spelled correctly and that you are connected to the server on which the file resides.Since no path works, it must be a syntax error, but I'll be darned if I can see it.
Full code of this routine is:
Dim connection As String = "Provider=Microsoft.Jet.OLEDB.4.0;" & "Data Source=" & fName & ";" & "Extended Properties=""text;HDR=YES;FMT=Delimited"""
Dim conn As New OleDbConnection(connection)

View 2 RepliesA While back I developed a application that connected to Excel using DB connection. It worked fine since the application was designed for usage on one particular PC with Excel 2003. I especially liked the solution since the data retrieval was much faster compared to what I would get if I connected to Excel using Interop libraries.
However, recently when I tried to implement the same solution onto another app that would run on various PC that could use different versions of MS Office I ran into multiple problems. First of all, I can't use the same connection string on various versions. Also, the whole x64 vs x86 thing is adding to the problem.
I wonder if there is a way to check the version and use the apropriate connection string for every version?

View 2 RepliesI have a problem with Oledb connection when I am trying to open an Excel spreadsheet:
[code]...
This piece of code works well on one computer, but on another the IMEX=1 doesn't seem to work, and the Jet seems to read the first few rows of the Excel spreadsheet that are numeric and decides that the whole spreadsheet is numeric, so it ignores some String values later in the sheet.
We're converting a Classic ASP site to an ASP.NET site. One function was to upload a 'template' of data in CSV format for importing into the database. There were several different record types in there (the first field always indentifies the type of data).The task was to get the CSV into a DataTable so it could be validated (new project is to have MUCH better validation rules)
The code seemed pretty straightforward - watered down (taking out comments, Try/Catch, etc) it is as follows:
Dim da As New System.Data.OleDb.OleDbDataAdapter
Dim cn As New System.Data.OleDb.OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & strDirectory & ";" & "Extended Properties=""Text;HDR=No;FMT=Delimited;""")
[code]....
The DataTable (dtData) is populated, but only starting with the second line of the CSV file DESPITE the fact that "HDR=No" is in the connection string.
