I compiled some VB6 code on my Win7 x64 machine and the result .exe will not run correctly on any other machine. VB6 code is just a new template .exe file with one button, a reference to "Microsoft ActiveX Data Objects 2.6 Library" and the following code in the button press event: Dim db Set db = New ADODB.Connection It runs correctly on my machine, but no others (even other Win7 x64 machines) (Update: I found TWO other users where it runs and one of them is Jeff Atwood!, but most machines have the same problem)

I have something strange occuring. The following code works 100% when run in VB2008 Express.When compiled and run onthe same system, it generates the above message.The codebasically opens a Access DB and loops thru the db There is a progress bar (also tried a simplelabel) to display progress using AbsolutePosition.
dbInUse.Open("Provider=Microsoft.ACE.OLEDB.12.0; Data Source=C:SCDBv4DataSCDBData.mdb")
rsInUse.Open(OpenCommandSQL, dbInUse, ADODB.CursorTypeEnum.adOpenKeyset, ADODB.LockTypeEnum.adLockOptimistic)

I have a .net application that uses customerrors web.config module to display meaningful messages for errors. It works without any issues for 500 errors/exceptions caused by non-ajax and ajax components (updatepanel). However, in a scenario where updatepanel's asynchronous request times out, there is no error raised at all. I was able to see the timeout in firebug and come up with a solution that would at least display the error message as an alert and then redirect the user to the 500 error page using javascript but it's not quite doing what the rest of the application does in case of an unhandled errors like these. I basically just want everything to go through "LogEvent" mechanism so based on the severity of the error, it does the necessary work.This 500 error page doesn't have anything in the Server.GetLastError() for these timeout scenarios. Is this an expected behaviour? Can it be changed so I do have access to these timeouts in Server.GetLastError() OR maybe just run this error through "LogEvent" mechanism? Is there a better/more graceful way to handle this issue?
Below is my code to give you an idea, not exactly what I have in my application but pretty close.
Web.Config
<customErrors mode="On" defaultRedirect="~/Errors/ErrorUnknown.aspx" redirectMode="ResponseRewrite">
<error statusCode="500" redirect="~/Errors/Error500.aspx" />
</customErrors>

So when i build or click debug on my program. No errors come up and its smooth. So i decide to publish my programme. However. I come up with a bunch of errors during the publishing.
Here they are:Error 1 Cannot publish because a project failed to build. 1 1 Simple CALC
Error 2 Unable to copy file "binReleaseSimple CALC.exe.manifest" to "binReleaseapp.publishApplication FilesSimple CALC_1_0_0_0Simple CALC.exe.manifest". The specified path, file name, or both are too long. The fully qualified file name must be less than 260 characters, and the directory name must be less than 248 characters.

I'm converting a VB6 + ADODB app to VB.NET 2010 and targeting both x86 and x64 I understand that ADO is available in both 32 and 64 bits and that .NET supports it.The VB6 code uses ADODB and ADOX to work with OleDb and Odbc data sources. It also uses the Jet and Replication Objects 2.6 library to compact and copy Access database files (if the uderlying database it's using is Access)I'm wondering if I should consider using OleDbConnection/OdbcConnection in the .NET version of the software or stick with ADO.I've looked at OleDbConnection, OdbcConnection and SqlConnection and can see that porting the old code over would be time consuming and risky.

I have a piece of software I am converting to ADO.NET from ADODB. In ADODB I can update a recordset by simply.
Dim rs as ADODB.Recordset
rs = query("select * from tblSomethere where something = something")
rs("something").Value = something.Text
rs.Update()
OR IF I WANTED TO ADD
Dim rs as ADODB.Recordset
rs.AddNew()
rs = query("select * from tblSomethere where something = something")
rs("something").Value = something.Text
rs.Update()
I am confused about to easily accomplish this. I know I can use an insert or update command but it would be much easier to do something like this. NOTE: The query just returns a filled RecordSet, it just executes the command and connection without me having to do it all over the place.

in vb.net, there are some applications that use adodb to access a mysql server.
[Code]...
re writing these functions is a big task - and I am not interested in doing it unless absolutely needed. Here is my problem though. even if the connection is closed (and i have stepped through the code, it closes) The connection is still visible on the sql server in a sleep state why? and how can i make sure that the connection is closed.

I've written some code to try some thing. I don't get an error message. However, the record count return " zero". I declare some objects and make a connection. That all works fine. But no records.
Here's the code :

Dim vtest As VariantType
Dim cn As ADODB.Connection
Dim rs As ADODB.Recordset
Dim cmd As ADODB.Command

I had the great fortune to receive the task of converting an ancient VBA Access order tracking application into a stand alone VB application. Along the way I was trying to parameterize their SQL queries, most everything has gone well but now I am getting an error I can't figure out."Item cannot be found in the collection corresponding to the requested name or ordinal."Iam kind of stuck using as much as the old code as possible because the client "knows VB" and wants to be able to edit the code after I'm gone.

The following VB code is from an application that I am developing. It establishes a record set by executing a SQL query on a SQL connection (ADODB). On the first pass through, the statement fails with an error 91, I trap it and re-execute the sub and then the statement works! The statement that fails is italicized and bolded below.

I am getting errors when I try to use this adodb.connection and command in my code. The error I am getting is saying that the connection and command are not defined. I read online that depending on your version of vb that you might use the "OLE" connection instead of ADODB.

My app currently uses Interop.ADODB.dll to retrieve data from an access database.My compiled setup file has to include a Interop.ADODB.dll file for the software to work.What would i have to do in order to convert my app to drop the interop file by using Ado.net instead?Would it simply be a matter of changing the references and connection strings or does it involve alot more than that?

We have had a visual basic.net (2002) service running on our server for several years now with no problems. However I recently needed to update one of the DB calls by adding additional fields to the SELECT statement. However, after adding the new fields, some of the returned data is coming back empty when I loop through the records. I have confirmed that the querystring is accurate and returns all of the data through a third party viewer, so I'm not sure what is going on.For example, in the code below, everything worked fine with field1, field2, and field3. However, when I add field4, data for field2 and field4 come back empty when looping through the results.

Using the ado.net connect schema you can get the schema from a access database. I can use the alter statement to add a field, but I want to update the descrption and default properties. Can the be done without using adodb or adox (com objects)?

I have a vb program accessing a table in an sql server database. I would like the vb program to wait if it attempts to update a row which is locked in the table. The default behaviour of the recordset seems to be fail immediately with a timeout if the record it wants to update is locked.
The sql server is set to a default lock_timeout of -1 (infinite I believe). Is there a way to have an ADODB recordset wait on a lock (say for 60 seconds) and then fail if it still can't update the record.
