问题 I need to enable or disable a control on a continuous subform, dependent on another field. The initial code I wrote by instinct was very similar to what is suggested here, but instead of only disabling those controls which are marked as "child", it disables all of them - in effect, it seems only to be looking for the value of the last record and affecting all the rows. Is there a way this can be achieved, or am I barking up the wrong tree? Code below: If Me.Record_Type = "Child" Then 'Disable

Trouble with InputBoxes

问题 What declarations I have to make in order to be able to use Excel objects and constants from my Access 2007 VBA script? Dim wb As Workbook or Set objExcelApp = New Excel.Application or .Borders(xlEdgeBottom) Thanks 回答1: First you need to set a reference (Menu: Tools->References) to the Microsoft Excel Object Library then you can access all Excel Objects. After you added the Reference you have full access to all Excel Objects. You need to add Excel in front of everything for example: Dim xlApp
