I am connecting to an Access database and using a parameter query with the LIKE operator to return all rows that match query. The string to search for is taken from a Textbox
sql =
"Select * FROM Allview WHERE Info Like" &
"*" &
CStr(TextBox1.Text) &
"*"
The query does not return any data in vb, but when run from access with same string, there is data returned.The connection to the database is done correctly, as I am able to return data with various other queries.

i receive an error. Why? Conflicts between access 2003 and vb.net 2010? SQL Server is better?And another question.

Is there a way to define into the parameters the d/M/yyyy specification?

The problem I'm having is it's returning the both InstName and the StuName multiple times in the listbox. I'm guessing it's because I'm doing the items.add twice?

The SQL string won't return data from Access. I've tested this exact SQL String in Access and it works fine.First of all, Am I getting a SQL query from Access in the proper manner?Second... should I be using a stored procedure for this?

I have an access query which plays flawlesly in Access.I want to use it as a source for a datagridview i use in one of my forms but....given the fact that is a rather big query with some "like" and conditions like ">3" and so on AND the fact it uses tables from 3 different mdb (not to mention is bases on other queries...i 'ill try my best to fix this) what is the best approach .
1st case .Can i retrieve the data simply with NO oledbparameteres and NO " select * xxx where yyy like 'd' ".I think there is a issue with the Oledb connection that "omits" them.To explain better the query right now with the filters in access returns 3 rows, without the filters 30 rows,can i get just the 3 rows to do my job... 2nd case . How should i fill a datagridview using tables from 3 different mdbs.If you can show me an example it would be life saving.
I have an application that uses an *.accdb file as the back-end database. Connecting to and retrieving data from the access file is not an issue and is working quite well. However, as a precaution, I have the application first check to make sure the database file exists in the application's folder while it loads up. As a convenience, if the database file is not found, then the application creates a new (structured, yet empty) database. The creation of the actual *.accdb file and the creation of the tables is complete and is also working well.
