VS 2010 OleDbDataAdapter And Excel?
Oct 16, 2010
I have had this headache for a few days now. Thought I had sorted it but haven't.I have copied worksheets from an excel workbook into a dataset, with each a datatable for each worksheet.
I then use a DataGridView to Display and edit the datatable.DataGridview.DataSource = MydataSet.DataTable(0) sort thing.But for some reason I just cant figure out how to write the datatable back to the excel worksheet.I have this but Im probably barking up the wrong tree.

filling an OleDbDataAdapter.I have:
Dim cmd As OleDbCommand = New OleDbCommand(myQuery), myConnection)
Dim da As OleDbDataAdapter = New OleDbDataAdapter()
Dim dtDonnees As DataTable = New DataTable()
da.Fill(dtDonnees)
Filling takes too much time.For 20 lines it takes 20 seconds.And for 130 000 it takes a little more (but not 130 000 sec).But 20 seconds is too much anyway.
Question part 2: can I skip fill?I mean, after filling the datatable, I do a for each row of datatable and cast into an entities:
Dim returnList As New List(Of myObject)(dtDonnees.Rows.Count)
For Each rowDonnee As DataRow In dtDonnees.Rows
returnList.Add(New myObject(rowDonnee))'set every data of the row into my new object
Next
Can I pass each row of OleDbDataAdapter?

I am currently trying to create a search function on a page in VB.NET which will allow me to search a database for a customerID from a textbox called txtSearch and then present it into a datagrid.
So far I can display the customerID's manually by using
SELECT * FROM Customers WHERE CustomerID LIKE 'A%'
but cant figure out how to replace the A with data which will be inputted into the textbox.

I have a field in a 2003 access database named first. I run the data adapter update command, gives me "Syntax error in UPDATE statement." I change the field name to firstName, try the update again, it works. I already have a bunch of programs using the database and using the field "first", do I really have to rename my field, go back and update all my programs to read from firstName instead of first? I really don't want to go that route if I don't have to. (provider=microsoft.jet.oledb.4.0)
*Edit: I meant to specify, I want the answer to use commandbuilder (but it won't work that way).

I am using vb.net 2003. In my program I access an Access database file via Jet 4.0 and OleDbDataAdapter.I have several tables constructed with text boxes that are filled with data using OleDbDataAdapter.Fill. This all works fine. When Integer data is displayed in the boxes it is shifted to the left as text. How do I format these textboxes when I am filling them with the Fill statement? I would like them numbers to be shifted to the right and have commas placed every third didgit.

I need to update more than one DataAdapters, so I used the
Dim sqlcmdbldUser As New OleDbCommandBuilder(dtaadpUser)
Dim sqlcmdbldPoints As New OleDbCommandBuilder(dtaadpPoints)
But only one of them works, the second one brings up errors if I try to update the DataAdapter. Is there a way of using and updating multiple data adapters?

I am trying to connect a VB.NET 2003 Oledbdataadapter through the wizard to a SQL Server 2005 Database, but i get an error message during the wizard.These are my steps:New Connection, Select provider (Microsoft OLE DB Provider for SQL Server), Select Connection:server name, log on: use windows NT integrated security, select database. I do all these steps then click "test connection" and it is fine, but when I click "ok" and error message pops up."Unable to connect to database. It is only possible to connect to SQL Server Desktop Engine databases and Microsoft Access Databases with this version of visual studio."

I've create a new VS 2008 Window Form Project using VB. I added an oleDbDataAdapter to the first and only form, set it to a table in my Access 2007 Database (there is only one table, PK field autonum of course and two Memo fields). The Database is in the Project's folder. A standard oleDb Connection object was created, as I expected, then I select the DataAdapter and choose 'Generate Dataset' which produces a standard DataSet called 'DataSet1.xsd'. Now when I build the project I get an error 'Error 1 Type 'FontTest.DataSet1' is not defined.' I do have a reference in my new Project to System.Data.So what the @#%$@ is going on? Why isn't the Dataset create by the DataAdapter being recongized? I can get into the DataSet Designer. The DataTable create is perfect, three columns defined correctly as I expected.

I need to import a .csv file so that it formats it all nice-nice so I can easily get the information from a column or row, then I need to grab certain rows, then reorganize it and save it into a different Excel spreadsheet for the program to then use. The original .csv does not contain the information in a way that we need it to be.
What I found so far: I saw this code snippet online
'-----------------------------------------------------------------------
' CONVERT CSV FILE TO XLS AND PROCESS XLS ROWS AND COLUMNS
' Opens Excel, imports .cvs file into xls format
' Iterates xRows and xCols from xls format

VB.Net 2010 program .exe on PC with Excel 2007 gives error when cannot find Excel version 14, which is Excel 2010 I have developed a program in VB.Net 2010 which reads from an Excel spreadsheet. It works fine in the IDE on my computer. I built an .msi and executed it on my computer. I get "Error: 53 - Could not load file or assembly 'Microsoft.Office.Interop.Excel, Version=14.0.0.0, Culture=neutral,PublicKeyToken=71e9bce111e9429c' or one of its dependencies. The system cannot find the file specified."
The only version of Excel on my computer is 2007, which is version 12.0.6557.5000. The version the error says it needs, version 14, is actually the version of Excel 2010.I have put in MsgBox statements to find where the error occurs.

I need to access the current instance of MS Excel. To do that, I wrote the following code:
Imports Excel = Microsoft.Office.Interop.Excel
Imports System.Diagnostics
Private _ExcelApp As Excel.Application
[Code].....
The code runs nice, but it has a problem: After the user close the Excel application (click button X - note: no other instance of Excel exists), if you open the Windows's task manager, its possible to see the process Excel.exe.
If I open and close the Excel application, there is no process Excel.exe, but if I run my code with the Excel application openned, after the user close the Excel application, the process Excel.exe isn't finished.
