Update Excel 2007 With OleDb?
May 7, 2009
Attempting to execute an update command against an Excel 2007 file gives the error:
Operation must use an updateable query. I'm using System.Data.OleDb with a connection string like this:
Dim strConn As String = "Provider=Microsoft.ACE.OLEDB.12.0;" & _
"Data Source=""" & pathToFile & """;" & _
"Extended Properties=""Excel 12.0;HDR=YES"""
I have tried setting ReadOnly=false but that gives Could not find installable ISAM. I have also tried setting Mode=ReadWrite and IMEX=1 which didn't seem to have any effect. My update command is like this:
Dim cmd As OleDbCommand = con.CreateCommand()
cmd.CommandText = "UPDATE [" + sheetName + "] SET [Quantity Error] = 'test' WHERE [Full Name] = 'Mr. Brown White'"
where sheetName was obtained from querying the excel schema. Is it possible to do what I am trying to?

I have some excel file, where I have to programatically delete all hidden columns.The problem if that, when I receive these files, the cells are mainly formulas, and as I delete some columns I get some "#REF#" problems.
I thought a bit about the problem an decided to create a function that loops throught all cells and replace the value by its own value, before deleting the columns, via OLEDB:
dt.Rows(row)(col) = dt.Rows(row)(col).ToString I don't know if this works. So I followed an update example I found in google, but it doesn't work:
Dim conexao_Excel As String = "Provider=Microsoft.Jet.OleDb.4.0;data source=" & fileName & ";Extended Properties=""Excel 8.0;HDR=Yes;IMEX=1;"""
cn = New OleDbConnection(conexao_Excel)
cn.Open()
da = New OleDbDataAdapter("SELECT * FROM [" & sheetname & "]", cn)
da.Fill(dt)

"Update requires a valid UpdateCommand when passed DataRow collection with modified rows." I image this is pretty basic, but I have already lost so much time on this issues...

Just wondering if i might hit a snag in my program. Ive got 10+ users using the same files, via a Oledb to put info into an excel spreadsheet. If 2 or more people save there file at the same time will the program go into read only on one person. Normally one 3 will use the file at one time. I know Sql itself would be better to use. best way i can describe it, normally using excel if you manage to open the same file twice one opens as normal but the other opens as a Read only file, will the same thing happen if im using Oledb connections?

I am using VS .net 2003 and developing a program that calls Excel. The development computer only has Excel 2003, and the target machine only has Excel 2007. Would it be possible to install Excel 12 Object Library in the development computer without installing Excel 2007?

I am trying to read excel data (Excel 2007 SP1, on Windows XP SP3) with visual basic .net 2008 (VB 9.0 SP1). I have tried several attempts and whatever I do I am getting the following error message: System.Runtime.InteropServices.COMException was unhandled ErrorCode=-2147319784 Message="Altes Format oder ungültige Typbibliothek. (Exception from HRESULT: 0x80028018 (TYPE_E_INVDATAREAD))" Source="Microsoft.Office.Interop.Excel" Message="Altes Format oder ungültige Typbibliothek." Translated: Old format or unknown type libraryI have added the reference "Microsoft Excel 12.0 Object Library" to my project. I am assuming that I might have to add a different or an additional reference, but I do not have any clue which one to use. List of things I have already done:- Searched other forums- Altered the language settings- Tried it on an other Computer (Win XP SP3, Excel 2007, Visual Basic 2008 Express)- Ran the diagnostics tool in Excel - Updated all updates etc...- Reinstalled Visual BasicI really do not have any clue why it should not work?

how I can use excel 2003 and excel 2007 on my application. I add a reference to Excel 12.0 Object but this one is not compatible with Excel 2007 and i think if i add Excel 11 Object it will not run on excel 2007.
Is there any solution that I can use so that my project can be used with either excel 2003 and 2007?

I have an application to re-sequence some items based on a an alphabetical ordering of the items from another table. I couldn't create an update statement to update the database when I pulled the information by a join query, So I pulled down both tables into a dataset with an XML Schema description where the two are related by the itm_id key as in the database. I then have two datagrids one with the items and one with the bound to the relationship this allows only the records associated with the itm to be displayed in the datagrid, I then run a loop that changes to sequence number for each corresponding record,this all works fine but then I go to update the back end database.
The update from the dataadapter executes successfully, but then if I reload the dataset from the database back end I find that the update did not actually update the records on the back end. The only record that was updated was the very first record which updated with a 0 then all the others did not take, I have re-run it several times and they will not take.
Me.Cursor = cursors.WaitCursor
odbaCatItem.MissingSchemaAction = MissingSchemaAction.AddWithKey

I have login system where once logged in, there is a global variable which holds the users ID. In another form, I have an SQL update which updates rows in the user table. So my dilemma is this: When I try to update it either updates the first user only, or all users.
The SQL I have :
Dim Update As String = _
"Update User Set field1=?, field2=? field3=?"
What I would like is...
Dim Update As String = _
"Update User Set field1=?, field2=? field3=? where ID =?"
However this doesn't work.

I am using asp.net oledb to export information to excel file. I encounter problems when the information to export becomes too big, in this case the code I have given below, the excel file generated becomes an empty spreadsheet.If I changed the loop to 1123 for insertion of the rows. The generated excel file is fine, 1125 rows, and 4 columns shown.A test program in windows form is also working fine regardless of how many rows.[code]I couldn't find a solution to my problem as well. What I did eventually was to run the process using another separate windows service. The code works perfectly fine running from a windows form or service program, but not asp.net, not sure why.

I have always used Excel.interop before but I thought oledb would be simpler because, for this application, I only have to read the data which it can't seem to do. It accesses the file alright because I can't open the file while I am at a breakpoint. It attempts to read the file because oExcelReader.fieldcount = 14 which is correct. oExcelReader.hasrows = true which is not correct. The line where I use getstring(1) errors out and says there is no data for this row/column.

Originally I was using Office Interop to import data, but that was a headache and a half for both me and my computer. Right now I'm attempting to load it with ACE, but my data grid isn't being populated. Once that's up and running I need to know how to use that data in other ways, and how to grab specific cells of data from that dataset. I'm using Visual Studio 2008, by the way.
