Se Adodc OR Even better.. ADODB. for this you need to get MDAC fromMicrosoft free download.(check under project_References- Microsoft DataActiveX objects.. the current no is 2.8. if it is not there download invb directory.

next, you can learn about creating a DSN from control panel, ODBC. onceyou learn this, connection becomes a piece of cake. get some free vbtutoriasl from WWW.

then

you need to use DAO or ADO to connect to the database. better study both but since ADO is current, i am showing that code.
under Menu Project_References, put a check mark on Microsoft ActiveXData Objects latest version (though it works for all, currently 2.8with sp pack 1 ).

at the general declarations:
dim conn as adodb.connection, rec as adodb.recordset, esql as string,esql1 as string
Private Function connect()
Set rec = New ADODB.Recordset
Set conn = New ADODB.Connection
esql = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & "D:VBDesigndhana2.mdb" & ";Persist Security Info=False"
'here you put the correct path of your mdb file. and check if you have jet 4.0

conn.Open (esql), , , 0
End Function

private sub form_Load()
connect
end sub
and for adding records:
say let us say you have 3 fields. then have 3 textboxes and 1 command button on the form.

private command1_click()
esql1="select * from Yourtablename"
rec.open(esql1),conn,, adOpenDynamic, adLockOptimistic
rec.AddNew
rec.Fields(0) = text1.Text
rec.Fields(1) = Text2.text
rec.Fields(2) = text3.text
' you need to check if in your access table design you have Allowed Zero length .. set it to Yes for all text fields.
rec.update
if not rec.eof then rec.movenext
rec.close
conn.close
set conn to nothing
end sub

this will add new records to access table from VB.
' for picture store the full path of the path and the picture file nameint the text field. and in the picturebox of VB form for viewingrecords again you need ADO or ADODC and here you code:picture1.picture=Loadpicture(rec.fields(3) ' depending on where thepicture field is located. you need to make a few trials.
under Menu Project_References, put a check mark on Microsoft ActiveXData Objects latest version (though it works for all, currently 2.8with sp pack 1 ).

at the general declarations:
dim conn as adodb.connection, rec as adodb.recordset, esql as string,esql1 as string

Private Function connect()
Set rec = New ADODB.Recordset
Set conn = New ADODB.Connection
esql = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & "D:VBDesigndhana2.mdb" & ";Persist Security Info=False"
'here you put the correct path of your mdb file. and check if you have jet 4.0

conn.Open (esql), , , 0
End Function

private sub form_Load()
connect
end sub

and for accessing records:

private command1_click()
esql1="select * from Yourtablename where id =" & val(text1) ' for integers

esql1="select * from Yourtablename where name=" & "'" & text1 & "'" ' for string

rec.open(esql1),conn, adOpenstatic, adLockreadonly

label1.caption =rec.Fields(0)
label2.caption= rec.Fields(1)
label3.caption= rec.Fields(2)
' you need to check if in your access table design you have Allowed Zero length .. set it to Yes for all text fields.

rec.close
conn.close
set conn to nothing
end sub


' similarly there are routines to ADD, Delete, Edit, View etc.

Use ADO and create a connection string for a Jet file (version matters here when creating the string). Then use ADO commands and return recordsets to buffer your data.

Retrieving acess data which is password protected thru VB


You will need to use a connection string. But - before you can configure the string correctly, I'd need to know how the data is stored (Access, SQL, ODBC, etc). You can find examples online. Just know that you are looking for "Connection String." Here's two examples:
1. For MS Access (Jet files):
' Set up the connection string.
m_strConn = "Provider=Microsoft.Jet.OLEDB.4.0;" & _
"Data Source=" & strDestDBPath & ";" & _
"Jet OLEDB:Engine Type=5" ' NOTE: Use Type=5 for Jet 4.x.

2. For SQL database:
g_strADOConn = "Provider=SQLOLEDB;" & _
"Data Source=SERVER_NAME;" & _
"Initial Catalog=DATABASE_NAME;" & _
"User ID=mssql_userid;" & _
"Password=mssql_password;"

What is the compatible database for visual basic 6.0?


Microsoft Access uses the Jet Engine. In VB 6, you can create a data connection using ODBC or OLE DB. Here is an example of OLE DB:

"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\YourAccessDB.mdb;User Id=;Password=;" Good luck

Ms access


Stored Procedures don't exist in MS Access. You do have the following options though. Queries, which are just select or action queries. VB Code, which you can write using Query Objects as if you were writing a Visual Basic application. These can be Functions or Subroutines. In these, you would use the standard programming techniques with while and for loops, etc.

You can create complex situations combining the two of these. A function in the VB code area can accept through parameters, the single values (line by line, record by record) in a query and act on them and manipulate the values.

For example: create a query that does a select phone from address. Create a function in vb called public function StripDashesInPhone(Phone as string) which then uses VB coding to strip dashes from each phone value passed in. To make it all work, in the query on one of the field columns put "NewPhone: StripDashesInPhone([Phone])" and for every record processed in the query, the function is called with the [Phone] field value passed in to the function and the action is processed and returned.

Other than writing a function that is activated by a form button click, which opens the current db and opens a table and process it, just like in VB, this is about as close to cursors and oracle procedures as you get.

I wish it was more, but ...
