No - you can only set it to a numeric value   zoom(50), zoom(100), etc.

This may work though if you're using web viewer: http://support.businessobjects.com/library/kbase/articles/c2002925.asp

My report in my VB.NET Project is already set as article c2002925.asp states.
I have a form that is 800x600 that has a Report Viewer on it where I view all reports.
If I load a report the viewer Zoom default is at 100%.

In the toolbar of the viewer you can select "Page Width", but this doesn't seem to work...
I will try the CrViewer1.Zoom 75 to see if that will work (I am assuming this is at 75%).

'create and fill the Data Adapter
                Dim oDa As New SqlDataAdapter(oComm) 'SQL Data Adapter object
                oDa.Fill(oDs, "spGetAFEHeaderReport")

                oComm.CommandText = "spGetAFEDetailReport"
                oDa.Fill(oDs, "spGetAFEDetailReport")

                rptAFE.SetDataSource(oDs)
                frmReport.rptViewer.Zoom(75) <------ I ADDED THIS
                frmReport.rptViewer.SelectionFormula = "{spGetAFEHeaderReport.varAFENumber} = '" & lblAFENumber.Text & "'"
                frmReport.rptViewer.ReportSource = rptAFE
                frmReport.ShowDialog()

It still does not work...100% Zoom factor when the form loads

First, set your zoom AFTER you set the viewer reportsource - just drop your zoom line of code down below 'reportsource' line.

Unfortunatelty you may also be caught with a known bug with the .Net version:  http://support.businessobjects.com/library/kbase/articles/c2013757.asp

I was involved in another discussion w/ someone who indicated he was going to try the approach in the link but was going to put in the form's activate or load or gotfocus events and see if it could be automatted w/out the button being needed.  Sadly I never heard if this worked but you may want to give it a try.

I put the code into the ONLOAD event of the frmReport...Must be that you cannot pre-define the zoom factor until a report is acutally loaded in the viewer...Thanks for the help

ebolek gets the points for giving me the code snippet:
CRViewer1.Zoom 2

I Tried you suggestion of setting it after REPORTSOURCE just for kicks and it did not work, it needs to go in the ONLOAD event of the form with the viewer after the frmReport.ShowDialog() command for it to work.
