Need help connecting database to form controls
« on: March 04, 2005, 04:02:03 PM »
I'm using Visual Basic 6.0 at work (AAARGH!).  If I were using 7.0, this would be no problem.  But with 6.0 I can connect to the database...I even get a confirmation of connection after clicking on the "Test Connection" button.  

But I cannot get any of the controls on the form to pick up any data from the database.  When I click on the text box's DataSource attribute, it only gives me DataConnection1 as an option, but I can find NO other reference to DataConnection1 in the project.

And HELP doesn't work, because I get an error message that says that the MSDN collection is not available and must be reinstalled.  But I have no idea who has the MSDN software in order to reinstall it.

At first I thought MSDN meant (M)icro(S)oft (D)umb@$$ (N)etwork....but now I know it for sure.

It is a MicroSoft Access 2000 Database.
Thanks,
Geo

I am using Access 2000 on a Windows 98 Dell Computer.  I'm not sure what other information to look for.

To access info from an Access database you should have something like

<%
dim cmd, conn, rs, strSQL
set conn=server.CreateObject("ADODB.Connection")
set rs=server.CreateObject("ADODB.Recordset")
set cmd=server.CreateObject("ADODB.Command")
filepath=Server.MapPath("database_path/here/database_name.mdb")
conn.open "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & filepath

strSQL = "SELECT * TOP 1 FROM database_name"
rs.open strSQL, conn, 1, 1

%>
<form>
<input type="text" name="field_name" value="<%=rs("database_field")%>
</form>
 

--------------------------------------------------------

That example will connect to your database and pull whatever data is in "database_field" and place it as the default value in your form field.

if you want to read from that form then just use

request.form("field_name")

That what yer lookin for?

Sort of, except that I don't know where to add this block of code.  In school, it was as drag-and-drop; so, I think the course left me rather crippled when it comes to older versions of visual basic.  (Come to think of it, I probably used Visual Studio .NET.)

Could you please tell me where I would place the code?

Sure man,
 Normally i put my connection strings in an include file below the root level, but for this example we can leave it in the main file.

---------- dbconn.asp ----------
<%@LANGUAGE="VBSCRIPT" CODEPAGE="1252"%>
<html>
<body>
<%
dim cmd, conn, rs, strSQL
set conn=server.CreateObject("ADODB.Connection")
set rs=server.CreateObject("ADODB.Recordset")
set cmd=server.CreateObject("ADODB.Command")
filepath=Server.MapPath("database_path/here/database_name.mdb")
conn.open "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & filepath

strSQL = "SELECT * TOP 1 FROM database_name"
rs.open strSQL, conn, 1, 1

%>
<form>
<input type="text" name="field_name" value="<%=rs("database_field")%>
</form>

<%
 rs.close
 set strSQL = Nothing
%>
</body>
</html>
-------------------------------------------

Now just save that file with a ASP extension and it will connect to your database fine and display the top record from the database into your form.

Okay, but I'm still not clear on where to put it.
We never worked with ASP files or root files.

It's for a local windows-based application.
