Good day all.

Here is some background.

I log on a table the Computer Names of all machines which launch my application.

I would also like to delete the name of the computer when they exit the application.

To that effect on my form Form_Close has the following code:

  Dim NBuffer As String
  Dim Buffsize As Long
  Dim Wok As Long
  Dim strComputerName As String
  'Dim wrkDefault As Workspace
  Dim dbs As Database
  Dim rst As Recordset
  'Set wrkDefault = DBEngine.Workspaces(0)
  Set dbs = CurrentDb
  'Set dbs = OpenDatabase("lcdb.mdb")
  Set rst = dbs.OpenRecordset("ActiveMachines")
'---------------------------------------------------------------------------------
'------------------------- Establishes Machine Name
  Buffsize = 256
  NBuffer = Space$(Buffsize)
  Wok = api_GetComputerName(NBuffer, Buffsize)
  strComputerName = Trim$(NBuffer)
'---------------------------------------------------------------------------------
'------------------------- Deletes the Machine Name

  dbs.Execute "DELETE * From " & "ActiveMachines where MachineName = " & "strComputerName;"
  dbs.Close

But it doesn't work. It keeps telling me : "Too few parameters. Expected 1.".


Help!

Thanks.

Be careful of double and single quotes:

dbs.Execute "DELETE * FROM ActiveMachines WHERE [MachineName] = '" & strComputerName & "';"

Greg.

Thank you very much for answering me. It seems to have helped. I still get an error but in the error message I now see the Computer Name.

Now this is the error I get when I use the line you provided me with:

Syntax error in string in query expression'[MachineName] = 'MTLACCOUNTING'.

If I remove the [] of MachineName I get the same error but without the []...

Thanks again Greg. Hope you or anyone else can help me with this one.

Read my code again on the web so you can see proper spacing and quotes. If you read this in e-mail, it'll look odd with the codes showing. Copy and paste it into your code exactly as I have it written.

Thanks for the prompt response. Copy and paste is what I had done. Nevertheless I repeated the excercise and copied and pasted it again. The exact error message I'm getting is:

Run-Time error '3075':

Syntax error in string in query expression '[MachineName] =
'MTLACCOUNTING'.

More info...

I clicked on Debug, and it brought me to:

dbs.Execute "DELETE * FROM ActiveMachines WHERE [MachineName] = '" & strComputerName & "';"

While checking the syntax, I placed the cursor on strComputerName and noticed that its value was "MTLACCOUNTING�".

So I got currious, and put the following line right before the above mentioned line: strComputerName="MTLACCOUNTING".

When I did this, it worked. So I think the problem is the � after MTLACCOUNTING.

So the question now would be does anyone know why I get that and more important how can I get rid of it!

Thanks.

How about if you did this? Add the TRIM function to the computer name... that is:

dbs.Execute "DELETE * FROM ActiveMachines WHERE [MachineName] = '" & Trim(strComputerName) & "';"

Same thing. I still get the "MTLACCOUNTING�".

[LGuzman]

Make sure there is no space between the " and the ' in the part of the expression that looks like this:

& "';"

Checked. No space. Same issue.
