i've developed a VB Net Application, that works with an access (2003) db. Now i've send it to a friend on mine with a new pc 64bit with win 7, and it doesn't works, more or less the error is: Quote:

I am using Visual Basic Express 2008 64bit on a Windows 7 64 bit computer. It is running Microsoft Office 2010 University Edition, which only comes in 32 bit so far as I know. I am able to connect to my access .accdb database from within Visual Basic, which I wasn't able to do until I came across this: [Code]...
Beforehand, I had recieved a "Microsoft.ACE.OLEDB.12.0' provider is not registered on the local machine." error, and after applying the above fix worked fine. However, now that I am trying to publish my program, I am returned with the same error, no matter what target CPU I select. The program works fine on 32bit machines, however on my 64bit laptop it is unable to connect to the database. I have tried compatibility mode, downloaded many different add-ons from the Microsoft download page, but to no prevail. My understanding is that it is not actually compiling the published version to x86, simply running it as such when I build it in Visual Basic, and because there is no apparent way to set target CPU for compiling,
I developed my application using vs2008 on a 32bit XP machine using ms access. My new machine is Vista 64bit using vs2008. Ms access has stopped working. It is looking for a 64bit software. Is there any? how do I work around this? will this hurt me when deploying to non 64bit machines?
View 3 RepliesI am connecting to Citrix database using SQL-defined ODBC. Having a problem with it. I am updating an existing application that uses the ODBC in SQL, and it connects fine. However, that database connection is secured, only available on the production side. The test side has a remote connection. I am attempting to change the remote connection values to match the parameters of the SQL-based ODBC, but the labels are different, and it doesn't seem to match. Specifically, I don't think I'm getting the DataSource correct. Also, it can't find the username and password that I use to log into the remoter connection - I get an error message "Invalid authorization specification".

For example, if I select 3 columns, 5 rows, only Column 1 Row 1 is displayed. Someone mentioned something about EOF but I can't find EOF code for OleDB. Should I be using another type of connection?;

I need to connect to an MySQL database in my VB.NET application (VB 2010 Express). When I attempt to use the Data Sources wizard to establish the connection, it does not provide an ODBC data source. I'm using Add New Data Source/Database/DataSet/New Connection which shows the Add Connection dialog. The only options it gives me for data sources are Access & SQL Server and the OLEDB data provider. It does not appear to give me the option of adding a new data source provider. Attached is an image of my current Change Data Source dialog. Where do I get the ODBC data source provider and how do I install it into Visual Studio?

View 3 RepliesI'm currently doing a project that includes access 2010 My question will be what driver can I use for an access 2010 *.accdb type file? For a *.mdb it works perfectly well with
ConnString ="Driver={Microsoft Access Driver (*.mdb)};Dbq=" & Application.StartupPath & "\CITSDB.mdb;Uid=Admin;Pwd=123;"
But, when I changed the mbd to accdb:
ConnString ="Driver={Microsoft Access Driver (*.accdb)};Dbq=" & Application.StartupPath & "\CITSDB.accdb;Uid=Admin;Pwd=123;"
It resulted in errors:
ERROR[HY000][Microsoft][ODBC Microsoft Access Driver]Could not find file '(unknown)'.
ERROR[IM006][Microsoft][ODBC Driver Manager]SQLSetConnetAttr failed

And then it shows me that my code for

IndexOutOfRangeException was unhandled

I knew it must be the driver but I don't know what accdb driver I can use for the connstring.

Well here I am again, could really use some expert eyes on this. I've got an update statement for access 2007 and when I run it it's giving me a "No value given for one or more required parameters." error. I've spent at least 2 hours on this now and searched all over the place and none of the suggestions I found are fixing it. I've got an insert statement to the same table that works fine, I took this same syntax for the update statement from another project where it was working perfectly. I've verified the spelling of the table and column names, As best as I can tell there are no reserved keywords being used and I've eliminated any spacing from the names. I've even tried updating a single row with no variables, just like for like data directly from the table and it still throws the error.

I have an Access XP database with two linked tables and a maketable query. I need to first run the Query through VB 2005 and then get the data from the resulting table created. But I get an error when I run the query as follows. I am getting the SQL Select statement from the SQL view in MS access after I create my Maketable query So it should be ok. I am saving the select in a hidden text box on my form.The query text :

I am trying to insert a variable in Decimal type into an Access table. When I use "decimal" field with 0 digits after the decimal separator (,) my program works properly. However, when i use the field with 2 digits after the separator I get a "Data type mismatch in criteria expression." exception. This happens also when I try to update the table. The debugger shows me that my variables contain the right values but the update or insert command gives the error.

We have developed a VB 2008 app that uses SQL Server 2005 Express to store data collected by this app. This app has been designed to allow multiple connections to the one centralized database.
I have ran a few tests, and confirmed that if one computer running our app is accessing a database residing on a different computer,and the network connection between two computers has been severed, it would take approximately 3.5 minutes before I would get a connection timed out exception error from within my code.
I have deliberately set the ConnectTimeout property in the SQL connection string to be 15 seconds. But some how, SQL database engine still retries until approx. 3.5 minutes later.
My thinking is that I have a subroutine that would attempt to open a database once a minute.If the open attempt is not successful, and resulted in an exception, then I would popup a message to notify the user that the connection is not available.
Doing it this way, I have confirmed that it would take about 1.5 minutes for it to re-establish the connection, once the actual network connection has been restored.
To make the long story short, I would like to find a way to shorten the detection for a broken connection, and let the user know sooner, rather than locking up the app during the 3.5 minutes period has elapsed, and at the mercy of the SQL database engine to timeout. And why would it take 3.5 minutes to timeout the connection attempt when I had explicitly use 15 seconds in my connection string?
I'm writing an application that imports and tidy up address data into a cleaned, deduped excel workbook ordered in rows with each column as an address field. One of the issues I've ran into is that we sometimes get a workbook where the multiple address fields are held in a single cell with line breaks. I've written code to extract all of this data out of the excel sheet in to a dataset with each sheet as a table and the address fields contained within. I now want to create a new Excel workbook from this data with the address fields in Row and columns the problem I have is I can Open/create the Workbook but when I try to insert a new Sheet (Table) I get an error saying the Workbook is read only....

I was wondering which way would be the easiest in VS2005 to connect to and pull data from a MS SQL database. I have already setup the database connection by choosing the datasource for a DataGridView but I'm not able to retreive any information.
The steps I have taken so far:
1. Make new form
2. Drag and drop DataGridView onto the form
3. Setup the data source and respective username password
Not sure where to go from here....
