thanks for ur help...

here is the complete code i used to test the countif function
Public XLApp As Excel.Application
Public XLWB As Excel.Workbook

Private Sub Command1_Click()
If WorksheetFunction.CountIf(Cells, "Some text") = 0 Then
MsgBox "Not Found..."
Else
MsgBox "found...."
End If


End Sub

Private Sub Command2_Click()
XLWB.Close False
Set XLWB = Nothing

XLApp.Quit
Set XLApp = Nothing
End Sub

Private Sub Form_Load()
Set XLApp = New Excel.Application

With XLApp
.Visible = True
Set XLWB = .Workbooks.Add
End With
With XLWB.Worksheets(1).Range("A1")
.Value = "Some text"
MsgBox .Text
End With

End Sub

One more important information is the countif function runs(shows the
msgbox) successfully for the first time. From the second time onwards it
throws the error message as "The method ~ of Object ~ failed".

if you need any further information i am pleased to give..

Show what code you are using, with the basic below that is working AND

You have set a reference to the Excel Type library ?

Then, test this basic code:
Private Sub Command1_Click()
Dim XLApp As Excel.Application
Dim XLWB As Excel.Workbook

Set XLApp = New Excel.Application

With XLApp
.Visible = True
Set XLWB = .Workbooks.Add
End With

With XLWB.Worksheets(1).Range("A1")
.Value = "Some text"
MsgBox .Text
End With


XLWB.Close False
Set XLWB = Nothing

XLApp.Quit
Set XLApp = Nothing

End Sub

Hi,
Thanks for ur reply.

i tried using the instance of Excel object instead of "Excel". then
also
my
application fails in the production environment(Windows Server2003).
is there any problem with the DLLs. If so please specify which DLL i
need
to update in the production machine.

You have to qualify the objects with the reference to the your

Excel, not Excel itself.

I suppose somewhere you have
Dim XLApp as excel.application
set xlapp=new....

so use
xlapp.WorksheetFunction.CountIf(oxlsheet.....

And qualify ALL the syntax from Excel used in VB6: e.g.
[A6], xlPart, xlFormulas etc.

Hi,

when i use the qualified names for the fucntions it works well in
my
system
but fails in the production environment. I tried the following
lines

Excel.WorksheetFunction.CountIf(oxlsheet.Range(oxl sheet.Cells(1,
1),
oxlsheet.Cells(1, 256)), rs1.Fields(0).Value) = 0 Then

and this line also throws the same error(ref previous post)

oxlsheet.Cells.Find(What:="'" & rs1.Fields(0).Value & "'",
After:=[A1],
LookIn:=xlFormulas, _
LookAt:=xlPart,
SearchOrder:=xlByRows, _
SearchDirection:=xlNext,
MatchCase:=False).Activate

What could be the problem?

As you are working in VB6, you need to qualify the objects that
are
not
part
of VB (as you have done with the Fields collection of the
Recordset),
otherwise VB does not know which library the objects are from.
You can use the Object Browser to see the object hierarchy. e.g.
XLApp.WorksheetFunction...
where XLApp is you instance of Excel

And Cells belongs to a worksheet. But as Bob says, use a range
rather
than
all cells on the required sheet.

When i am using the following line of code in my VB6.0 Program

"If WorksheetFunction.CountIf(Cells, rs1.Fields(0).Value) = 0
Then"

the application always throws the following Error message
which is
not
understable
"Method '~' of object '~' failed"

Can anyone throw some light on this issue.
