expression.FrozenColumns
expression Required. An expression that returns one of the objects in the Applies To list.
Remarks
Frozen columns are displayed on the left side of the datasheet and don't move when you scroll horizontally through the datasheet.
Note The FrozenColumns property applies only to tables, forms, and queries in Datasheet view.
The FrozenColumns property is set by Microsoft Access when you click Freeze Columns on the Format menu.
In Visual Basic, this property setting is an Integer value indicating the number of columns in the datasheet that have been frozen by using the Freeze Columns command. The record selector column is always frozen, so the default value is 1. Consequently, if you freeze one column, the FrozenColumns property is set to 2; if you freeze two columns, it's set to 3; and so on.
This property setting is read-only in all views.
When you freeze columns by using the Freeze Columns command, Microsoft Access automatically moves the columns to the leftmost edge of the datasheet in the order in which you freeze them. For example, if you freeze three columns, these become the first, second, and third columns in the datasheet. Because the record selector column is always frozen, the FrozenColumns property in this case will be set to 4. The three columns you freeze will have their ColumnOrder properties set to 1, 2, and 3 (in the order they are frozen).
If you click Unfreeze All Columns on the Format menu, all frozen columns will be unfrozen, and the FrozenColumns property will be set to 1.
Note The Unfreeze All Columns command will not restore the original order of columns if the Freeze Columns command caused the column order to change.
Example
The following example uses the FrozenColumns property to determine how many columns are frozen in a table in Datasheet view. If more than three columns are frozen, the table size is maximized so you can see as many unfrozen columns as possible.
Sub CheckFrozen(strTableName As String)
Dim dbs As Object
Dim tdf As Object
Dim prp As Variant
Const DB_Integer As Integer = 3
Const conPropertyNotFound = 3270 ' Property not found error.
Set dbs = CurrentDb ' Get current database.
Set tdf = dbs.TableDefs(strTableName) ' Get object for table.
DoCmd.OpenTable strTableName, acNormal ' Open table.
tdf.Properties.Refresh
On Error GoTo Frozen_Err
If tdf.Properties("FrozenColumns") > 3 Then ' Check property.
DoCmd.Maximize
End If
Frozen_Bye:
Exit Sub
Frozen_Err:
If Err = conPropertyNotFound Then ' Property not in collection.
Set prp = tdf.CreateProperty("FrozenColumns", DB_Integer, 1)
tdf.Properties.Append prp
Resume Frozen_Bye
End If
End Sub
