[Netprice] You can also do the same thing with the subject (for example, set r=reports! [Myreport]). When you are only accessing a form or a list once in a function, you may not get much benefit in terms of speed performance, but once you start the access operation in the same form or in the list more than once, you will see a noticeabl

Windows10 sometimes cannot access shared folders on a local area network. Will prompt for no permissions.If the shared folder is already set to everyone, then Windows 10 is typically logged in with a Microsoft account.There are two scenarios that can handle this situation.One is to modify the login to a local account. One is to add Windows credentials.Here's how to add a voucher method.1, open the "Control

Autokeys, Autoexec, and Addmenu operations, these three macros have no corresponding equivalence classes in Microsoft Access, so you can only use them. However, you can overcome the limitations of Autoexec by defining Autoexec to call your Access Basic Autoexec function. Optimize data type declaration When you declare the data type in your code, you should try t

By selecting the "Start" option in the "Tools" menu, you can specify a custom startup form, menu, or even custom title and icon. You can also choose to cancel the Database window to hide these objects for application users who lack the

process calls Avoid using subprograms or functions in the loop body. Each call increases the coding burden due to extra work and time. Each call requires that the local variables and parameters of the function be pushed to the stack. The stack size is fixed and cannot be increased at will, and shared by Microsoft Access at the same time. Exercise caution when us
