DB/Reporting :: Provider Cannot Be Found - Code Attempting To Access An Oracle Database
Mar 29, 2012I recently upgraded my system to Windows 7 64bit and ever since then I have had nothing but issues with my code attempting to access an Oracle database. I was using msdaora for my connection string however that does not work in 64bit. I changed over to OraOLEDB.Oracle which everything I can find on Google says to use however it fails every time. I have installed Oracle 11g 2 times now and even tried reinstalling VB.net 2010 and still no luck.
Here is my connection string....
Code:
MyConn.ConnectionString = "Provider=OraOLEDB.Oracle;Server=emsp.grhq.XXXX.com;Data Source=emsp;User Id=XXXX;password=XXXX"
And I am inporting....
Code:

Yet when I try it says...

Forms :: Error Handling - No Row At Position 0 - Need Code To Ignore Row When No Data Is Found?

IDE :: 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.

VS 2010 - Database File Cannot Be Found After Adding UserControl
Aug 30, 2011After adding a UserControl to a form which access my database I get this warning:
Warning1The database file cannot be found. Check the path to the database.
[ Data Source = C:Program Files (x86)Microsoft Visual Studio 10.0Common7IDEDatabase.sdf ]
C:UsersUserDocumentsVisual Studio 2010ProjectsProject1Project1Options.Designer.vb2160
Thing is I never had a database at that location, my database is and has always been in MyDocuments in the Project folder itself. There is nothing anywhere in my code referring to that database! When I double click it I get sent to this line in the Designers window:
Me.Controls.Add(Me.BoxControl1)
Even though I get this error I can still access my database, so basically it does absolutely nothing except drive me mad! So how do I fix this?
