Change Excel Odbc Connection?

Oct 6, 2009

I have an excel with 10 sheets, each sheet has a connection stored in it because i am using the ms query to read data from access database. when I code the below, both line are accepted by vb.net (with new or without)

Dim wb1 As Excel.Workbook
Dim wb2 As New Excel.Workbook

Now when I code

Dim wb_cnn1 As Excel.ODBCConnection ' Works Fine
Dim wb_cnn2 As new Excel.ODBCConnection ' Error 'New' cannot be used on an interface.

Q1: Why I cannot create New Excel.ODBCConnection? I have this

Dim xlsApp As New Excel.Application
Dim wb_cnn As Excel.ODBCConnection
Dim wb As Excel.Workbook

[code]....

Maybe because it is read only. I want that because the ms query is hardcoding the path of the access db even if i choose DSN so, if I change the location of the access file the query in the excel will not work, Q2: How I can change the connection in the Excel sheet?

Import Excel Data Into SQL Server - ERROR: "ODBC --Connection To {SQL Server} Servernamesqlservername Failed"

Aug 13, 2010

I am trying to do something fairly simple.. allow my user to import thier data from Excel into SQL Server, where it can be used by the application.To do this, I'm using the fairly simple code that is common everywhere I look:

strFilePath = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + fdlgFileOpen.FileName + ";Extended Properties=Excel 8.0"
connExcel = New OleDbConnection(strFilePath)
connExcel.Open()

[Code]...

Now, on my development computer this code works perfectly.  The data imports, and I can go on my merry way.

On the TEST computer, this code throws the error: "ODBC -- Connection to {SQL Server} servernamesqlservername  failed."  This seems very odd to me, because I'm using exactly the same SQL Server and database to interact with the application, and all the other screens in the application work perfectly.  The test computer CAN connect to this SQL Server, but it keeps throwing this error whenever I try import data from Excel.I've tried everything I can think of - using the server's IP address instead of the server name, sending the SQL Server administrator data along with the request, taking out the Trusted_Connection=Yes... nothing works.  What is going on here? How can this code work fine on my computer, and hiccup on another?

Difference Between Oledb Connection And Odbc Connection?

Nov 9, 2009

i 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.

Keep A Odbc Connection Open?

Jan 14, 2011

I'm trying to connect to a database and keep the connection open for any amount of user activity/queries within the database. Currently I have a connection that opens and closes for any query (save, update, etc...) which requires the logon process to the back-end every time the user saves etc... Is there a way to simply connect and leave the connection open so there won't be a lag time when running the query due to the logon process? This is what I'm using:

Private sConStrFormat As String = "Provider=TDOLEDB;Data Source=TDDEV;Persist Security Info=True;User ID={0};Password={1};Default Database=bcpm_ddbo;Session Mode=ANSI;"

Oracle ODBC Connection Monitoring?

I'm trying to develop a simple app with vb.net in VS 2010 that could monitor the ODBC connections via DSN made on the macnhine running this app.My scenario is an application (non Vb) running on a workstation that connects to an MS Access database on a network share.

The application (non Vb) connects using a link (ODBC connection via Oracle 10G) to the tables on the Oracle side.My VB.net Application should monitor the machine running the main application for ODBC connections drops and alert me via email for example.My question is where in the framework can I find something to instantiate or reference in order to check ODBC connections states constantly as well as network disconnection issues as well so I can log and /or alert when possible for network problems and ODBC connection problems for all the applications that might run on the host (machine running my vb app).

ODBC Connection To Excell Eats First Row - How To Stop It

I'm using Visual Studio 2005 Pro. I have an ODBC (not OLEdb) Connection to a spreadsheet. Works fine except the first row is missing. How do I stop this behavior? I can see that for OLEdb there is a way to suppress this behavior using the HDR=No parameter in the connection string. When I try that for the ODBC connection, No change. Row Still Eaten. I also went to the HKLMSoftwareMicrosoftJet4.0EnginesExcel registry key and changed the FirstRowHasNames value to 00. No change. Row Still Eaten.

Cast A Data Type With The Odbc Excel Driver?

Feb 4, 2011

I'm using the Microsoft Excel Driver to import an Excel document into a adodb.recordset so that I can remove duplicate rows and put it into the SQL Server database.

The first column has values like 192, 13U, JJJ, etc. but for some reason the query casts it as a double value, and any rows with alpha values get converted to Null. From what I can tell this is because the Majority type is numeric instead of text.

I tried casting it, but got an error.

Using ODBC Works Fine On 32-bit But Unable To Locate ODBC On 64-bit

When the report is run seperate on its own, on the exact same pc through crystal reports desginer it runs fine, Its almost like the application is not picking the 32-bit ODBC set up is it the case that the connection needs to be coded rather than using the report connection,

Formatting Excel - If I Try Using Style.numberformat With The Date And Time Formats, They Don't Change And Are Entered As If Didn't Change The Format?

Mar 11, 2011

I am throwing some data out into Excel and am having some formatting troubles. I have 5 columns (date, time, a long number I don't want displayed in scientific notation - text is fine, text, text). I can get it all working with numberformat, however I have to do them different ways.

Date works this way cell.numberformat = "m/d/yy" and it formats it to say 3/1/11

Time works this way cell.numberformat = "h:mm AM/PM" and it formats it to say 8:07 AM

For the long number cell.numberformat = "@" and it doesn't change the format and it gets displayed in scientific notation

BUT if I use cell.style.numberformat = "@" it works as it should, but it messes up all of the date and time cells. Apparently when you use style.numberformat, it doesn't just apply to the cell you're working with. If I try using style.numberformat with the date and time formats, they don't change and are entered as if I didn't change the format at all.

Universal Way To Connecting To Excel Through OleDB Connection?

Nov 17, 2011

A 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?
