dlookup problems

[sdel_nevo]

Hi all

i have a database that creates work tickets which is working really well, the problem i have is this.

I have a form "Support Form" that collects the computer name in a text field called "text142" when the form opens, this is done by using a module using this code.

Option Compare Database
Option Explicit

Private Declare Function GetComputerName Lib "kernel32" _
Alias "GetComputerNameA" ( _
ByVal lpBuffer As String, _


ByRef nSize As Long) As Long


Function ComputerName() As String
Dim stBuff As String * 255
Dim lAPIResult As Long
Dim lBuffLen As Long
lBuffLen = 255
lAPIResult = GetComputerName(stBuff, lBuffLen)
If lBuffLen > 0 Then
ComputerName = Left(stBuff, lBuffLen)
End If
End Function


what i am trying to do is lookup the ID of the computer in the "Asset" table using the name of the PC "AssetName", and put the ID in a text field called "answer"
all the computers on our network use the naming convention PC-**-** were ** is either a letter or number

i am using this as my dlookup

Me.answer = DLookup("[AssetID]", "Asset", "[AssetName]= " & [ComputerName])

the problem i have is that the look up always give this error

Runtime Error 2471
the expression you entered as a query parameter produced this error 'PC'

any help would be fantastic

Hi All

i have managed to get the dlookup to work using this code

Me.Text14 = DLookup("assetID", "Asset", "AssetName = 'LT-IT-02'")

me.text14 is the name of the textbox that i want to show the ID of the asset with the name LT-IT-02 this works correctly and returns the value 66 in the text box "me.text14" when i open the form

if i replace
Me.Text14 = DLookup("assetID", "Asset", "AssetName = 'LT-IT-02'")
with
Me.Text14 = DLookup("assetID", "asset", "AssetName = 'ComputerName'")

me.text14 is empty when the form loads and i do not get any errors

any ideas??

i must be doing something really silly but can't find my error.

Cheers

Steve

You need quotes around the [ComputerName].

Me.answer = DLookup("[AssetID]", "Asset", "[AssetName]= '" & [ComputerName] & "'")
