Execute SQL Statements To A MySQL Database Through ADODB.Connection
Sep 2, 2009We have a VB6 program that uses an ADODB.Connection to establish a database connection and use its execute function to run SQL statements. The connection we have established is to a SQL Server. It has been working fine. Currently, I am trying to change the connection to a MySQL database. I changed the connection string and the connection is ok.
However, when it comes to running the execute function, it returns a runtime error 3246 - connection object cannot be explicitly closed while in a transaction.
I checked the connection.status before calling execute and found that it is open. When I use MySQL's server connections to check the status, I found that there was a connection before and after execute was called.
I encountered this same error whether I used MySQL ODBC 5.1 Driver or MySQL ODBC 3.51 Driver.
VS 2008 - Add Microsoft ActiveX Data Objects 2.5 Library From COM References - Dim Con As New ADODB.Connection
Sep 2, 2010I am having problem with Visual Studio 2008.... When i add the Microsoft ActiveX Data Objects 2.5 Library from COM References, and just run the blank form, it runs perfectly....

View 1 RepliesNot All Results Returned From ADODB Connection?
Jun 1, 2010We 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 In Asp.net An Unmanaged Dll From .asp That Requires An Open ADODB Connection?
Dec 17, 2009I want to access the methods of a dll that is not managed. Seems to be vb6 from my best guess and what I know about the program.That part I have managed to figure out. If I drag the x.dll to my bin folder, the interpreter wrapper is created, etc. I can access the methods in the dll just fine. The problem is the database connection.
For informational purposes: The dll is compiled for a vbscript .asp website. There are a few methods in the dll that just manipulate the input (which I can access error free- its how I tested the dll usage), but most make a db call to get or set or update, etc. data in the db. The dll expects an ADODB connection. The asp files are setup such as:
set DllObj = server.CreateObject("dll.class")
set connect = server.createobject("ADODB.Connection")
connect.open "SystemDSNName","user","password"
[code].....
It is using a DSN but just as easily could be a DSN-Less connection. My problem is that the dll expects the connection to be open and available to it. Can I make a ADODB database connection available and open for this dll in a vb.net asp.net website.Basically,I need to use the business logic and db data changes through this dll, but want to make the front end in asp.net.I know there is an ADODB namespace in .net somwhere and I tried using it but it was not doing the job and really, I did not quite understand how to.

Jul 14, 2009I have upgraded my VB app from VB to VB.NET and its working fine. Now, I want to convert my existing DB connection strings from ADODB to ADO.NET so that I dont have to use MS Access on every client which runs this app. Currently the VB app looks up into an Access db to get the server ip, username, password etc. I aim to hardcode these values so that I wouldn't need the Access db anymore. Any inputs on how this could be done?

View 2 RepliesIDE :: Failed To Retrieve Data From The Database, Database Vendor Code 9421?
Jan 17, 2011I have a report made in Crystal Reports XI. The report is generated and exported to PDF in visual basic script using COM interface. Generally everything is running smoothly, but in one case generation breaks with error: Failed to retrieve data from the database. Details: [Database Vendor Code 9421]
Database used is MSSQL 2005 connected over ODBC to CR XI. When I am opening report with exactly the same parameters in Designer, everything works fine.It looks like it is data related, but it is hard to trace since the whole report is pretty sophisticated. Anyway I spent half a day on crawling over Dr. Google and it seems that he has no clue what might be an issue.
Retrieve Data From A Datagridview Loaded With Data From A Linq Database
Apr 9, 2010I have three tables in SQL server which I would like to show and access on a form. Table 1 contains account data, address, contact details etc. Table two contains data attached to a Person, tel no , Mobile no, Email etc. Table three contains details on what awards the person holds, i.e. one person can hold several awards.
Therefore I have a one many relationship between the first two tables and a one many relationship between the second two tables. This is set up in SQL
The first two tables are shown on a form, table 1 via a set of text boxes, table 2 via a datagrid control.
I would like the functionality whereby I could select a row in the datagrid showing the persons name and find the Persons_ID number then use that as a filter to a second datagrid view so that only the selected persons awards show in the datagrid.

How can I make sure the data being retrieve follow the alignment of database?
