Help with IIS server Error (Provider error '80040154' Class not registered)
I get the following error when I try to load the page: Provider error '80040154' Class not registered http://www.assetresearch.com/clog/count.asp I believe permissions for the IUSR_machine are correct as I am able to add and delete records from the database through other ASP pages in the site. Any ideas on what Class needs to be re-registered. If so, how do I do it? <% set conn=Server.CreateObject("ADODB.Connection") conn.Provider="Microsoft.Jet.OLEDB.4.0" conn.Open(Server.Mappath("clogin.mdb")) conn.CursorLocation = 3 set rs=Server.CreateObject("ADODB.recordset") sql="SELECT * FROM users" rs.Open sql,conn if rs.Supports(adApproxPosition)=true then i=rs.RecordCount response.write("The number of records is: " & i) end if rs.Close conn.Close %> Any help is this matter is greatly appreciated:) -- Best Regards, Martin Franklin Ma***@AssetResearch.Com Asset Research Services, Inc.

Anyways, you set cursorLocation to 3 above, so you have a client-side cursor that automatically supports recordcount because a client-side cursor is always a Static cursor which supports recordcount. > i=rs.RecordCount As a guess, you have an Access97 database which uses Jet 3.51, and you are > response.write("The number of records is: " & i) > end if > rs.Close > conn.Close > %> > > Any help is this matter is greatly appreciated:) using the Jet 4.0 provider to open it. I have never had a problem with this, but then again, I never use the RecordCount property, so this error may have been waiting in the wings for me all this time.

One thing I failed to mention in my original post is the fact that this code works on my testing server. My problem arises when I try to run the same page on my ISP's web server. I've actually tested this code on two of my own web servers without any problems. Line 17 pertains one of the following lines of code below. My development tool lists line 17 as 'rs.Open sql, conn' but I believe the true offending line of code pertains to the line below it 'i-rs.RecordCount' . rs.Open sql,conn i=rs.RecordCount I've further trimmed my code as suggested by removing 'if rs.Supports(adApproxPosition)=true then' . Thanks for the catch. My new complete code is... <% set conn=Server.CreateObject("ADODB.Connection") conn.Provider="Microsoft.Jet.OLEDB.4.0" conn.Open(Server.Mappath("clogin.mdb")) conn.CursorLocation = 3 set rs=Server.CreateObject("ADODB.recordset") sql="SELECT * FROM users" rs.Open sql, conn i=rs.RecordCount response.write("The number of records is: " & i) rs.Close conn.Close %> Perhaps my question would be better suited for a form on IIS config. Any further suggestions are greatly appreciated.

I had to extend the IUSR permissions on the directories that were pointed to by the TEMP and TMP system variables. "Note The Microsoft Jet database engine uses the System Temp and Tmp environment variables to specify the location of temporary files that are created during Jet operations."
