It will only be caused if you have some connection left open

Thanks for answering. At last, I found the source of problem, beacause I turn on SQL Debuging mode in Visual Studio IDE. If I turn off that mode, the problem did not apprear again.
Thanks

Private Sub Command1_Click()
Dim con As New ADODB.Connection
Dim sqlcon As New ADODB.Connection
Dim rs As New ADODB.Recordset
' Excel sheet
Path = "C:\ramani\book1.xls"
ssql = "Provider=Microsoft.jet.oledb.4.0;Data Source=" & Path & ";Extended Properties=Excel 8.0"
If con.State = 1 Then con.Close
con.Open ssql
ssql = "select * from [sheet1$]"
If rs.State = 1 Then rs.Close
rs.Open ssql, con
'Sql server
ssql = "Provider=sqloledb;Data Source=IBMX225;Initial Catalog=Master;User Id=sa;Password=;"
If sqlcon.State = 1 Then sqlcon.Close
sqlcon.Open ssql
While Not rs.EOF
sstr = "insert into excel values(" & rs(0) & ",'" & rs(1) & "')"
sqlcon.Execute sstr
rs.MoveNext
Wend
End sub

I use this code to setup a connection to a CSV file:
ConnectionString = "Provider=Microsoft.Jet.OleDb.4.0;Data Source=" & Server.MapPath("Sql\C_Registered_horses.csv") & ";Extended Prperties=""text;HDR=Yes;FMT=Delimited"""
Dim QuerySQL As String
QuerySQL = "SELECT * FROM C_Registered_horses.csv"
Dim objConn As New OleDbConnection(ConnectionString)
Dim objCmd As OleDbCommand
objCmd = New OleDbCommand
objCmd.CommandText = QuerySQL
objCmd.Connection = objConn
But when i execute the objConn.Open() i get the error:
System.Data.OleDb.OleDbException: Could not find installable ISAM
Any idea's

Im guessing the problem is with the connection string.
snipt from ADO Connection Strings[^]
strConnection = _T("Driver={Microsoft Text Driver (*.txt; *.csv)};"
"Dbq=C:\\DatabasePath\\;Extensions=asc,csv,tab,txt;");
If you are using tab delimited files, you must create the schema.ini file, and you must inform the Format=TabDelimited option in your connection string.
for more help with connection strings see ConnectionStrings.com/[^]

I am sorry to say but using:
ConnectionString = "Driver={Microsoft Text Driver (*.txt; *.csv)};Dbq=" & Server.MapPath("Sql\") & ";Extensions=asc,csv,tab,txt;"
gives a error:
An OLE DB Provider was not specified in the ConnectionString. An example would be, 'Provider=SQLOLEDB;'.
What does the _T mean on the start of the sequence

taken from connectionstrings.com
"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=c:\txtFilesFolder\;Extended Properties=""text;HDR=Yes;FMT=Delimited"""
"HDR=Yes;" indicates that the first row contains columnnames, not data
Hmm, I see this is VB.NET, right? First example wont work. Hows this work?
Connection="Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & Server.MapPath("/Sql\") & ";Extended Properties=""text;HDR=Yes;FMT=Delimited"""

Seems i forgot somehow the extra "". Would think that these extra's might not work in a string. It now works thanks
|
|
|
|

Your welcome.
The extra "" are escape quotes so it includes one of the quotes as part of the string. Without those it doesnt get a fully qualified string (for the oledb connection)

Now i would like to display all the data in a Datagrid using:
Try
objConn.Open()
dg1.DataSource = objCmd.ExecuteReader()
dg1.DataBind()
objConn.Close()
Catch Err As Exception
ltlError.Text = Err.ToString()
Finally
objConn.Close()
End Try
but i only get the first column and not the 4 other. How come.

Not sure to tell you the truth, I dont know VB.NET. If I had to venture a guess thought the problem probally related to whats being pulled from the CVS file.
Create the DataReader and loop through it output the results to the debuger. Eliminate that as a posible cause.
My guess would be that when getting the data from the CVS file its not getting all of the rows / cols. Or there is a problem with the Columns in the CVS file. Hmm then again you might have to experiment with the datagrid itself. Is it expecting to recieve the data in the manor in which your providing it?

You have a missing opening bracket after values

I've just been posed a challenge: to update a DataGrid on one client when another client changes the source table for that grid on a central database, all three connected on a standard TCP/IP network.
Now I vaguely (probably incorrectly) remember something about earlier versions of ADO being able to detect changes in source data, but I may be senile already, so I said, "Yes, it's possible!"[1]
Assuming there is no built-in way to detect these changes, I envisage several possible extrinsic solutions:
1. When other clients update the row, inform them it has changed since they read it.
2. Have each client broadcast the table/row ID to all others when they change it.
3. Have the database broadcast the table/row ID top all clients when it changes.
The last two then involve interested clients fetching the current version of the row if necessary.
It all seems rather messy, but this is not an uncommon problem, so what do I do?
[1] It's not official work, so I'm allowed to do that.

The solution depends upon how close you need to keep the synchronization. If 5-10 seconds is fine, you can just keep a TimeStamp on the rows. Every so often, send the client to request any rows that exceed it latest TimeStamp. It will usually return zero records and nothing needs to be done. This does require that rows be marked for deletion instead of physically deleted immediately.
The other solution I have used is to create a service and all clients access the data through it. It is then easy to send update notices down the socket to each client. I try to avoid this solution since it will complicate future maintenance.

Never mind complicating current development.
Thanks, I think I'll look into the first solution. I suppose I could get a separate DataSet of changed rows and merge it into the DataSet behind the display, no?

Can we insert a record directly into ms-access table using sql stored procedure?
could anyone help me.

Add the Access database to the SQL Server as a "Linked Server" then you should be able to write an update statement from a regular SQL statement.

What do you want to do. Update MS-Access Database with the stored procedure of SQL server or have your own update stored procedure for MS-Access.

I have read article "Making ATL OLE DB Provider templates support updating of data" at www.codeproject.com. Through reading your article, you must be a professional in "OLE DB Provider" field, I think so. Now, would you like to give me some help about this issue? You will be pretty appreciated.
1. In the file "IRowsetChangImpl.h" of your "Simple Data Object with update support", there is a row of code "HRESULT hr = pT->GetDataHelper(hAccessor, pColInfo, (void**)&pBinding, pDstData, cCols, spConvert, pRow);"(lies in method "SetDataHelper"). But there is not definition and implementation of "GetDataHelper". How to resolve it?
2. Now, I'm building up a updatable OLE DB Provider. This provider will be run in MS SQLServer DTS. First "Transform Data Task" of MS SQLServer DTS get the rowset from SQLServer, then call this provider, and pass rowset data to my provider by calling IRowsetChange::SetData(HROW hRow, HACCESSOR hAccessor, void* pSrcData). My questions are as following:
1) "Transform Data Task" pass the new data(a row of data include 10 columns) to my provider through method "SetData(HROW hRow, HACCESSOR hAccessor, void* pSrcData)". Is it correct?
2) I have get the DBBINDING info by the next code:
STDMETHOD (SetData)(HROW hRow, HACCESSOR hAccessor, void* pSrcData)
{
DBACCESSORFLAGS *pdwAccessorFlags;
DBCOUNTITEM *pcBindings;
DBBINDING **prgBindings;
DBBINDING *pBindings;
pdwAccessorFlags = (DBACCESSORFLAGS *)::calloc(1, sizeof(DBACCESSORFLAGS));
pcBindings = (DBCOUNTITEM *)::calloc(1, sizeof(DBCOUNTITEM));
pBindings = (DBBINDING *)::calloc(1, sizeof(DBBINDING));
prgBindings = &pBindings;
HRESULT hr = this->GetBindings(hAccessor, pdwAccessorFlags, pcBindings, prgBindings);
return S_OK;
}
Now, how can I extract data from pSrcData? I'm puzzled.
Expect for your reply!
Thanks in advance!

Hi All,
I am using SQL server 2000, one of my data base log file size has reached to the size of 30 gb. Even after transactional back up size did not decrease. Then I delete the log file and recreated it, still it is growing remarkably.
My datbase setting for Recovery Intreval is 0(zero) minutes.
Can anybody tell me why this file is increasing so fast?
Thanks for the help.
