When you compile a module in which a procedure is trying to call a procedure that is defined in a class module in another database, you may receive the following error message:
Method or Data Member not Found.
Class modules are private in scope to the Visual Basic project in the database in which they are defined. Therefore, procedures in class modules cannot be referenced in another Visual Basic project.
This article assumes that you are familiar with Visual Basic for Applications and with creating Microsoft Access applications using the programming tools provided with Microsoft Access. For more information about Visual Basic for Applications, please refer to your version of the "Building Applications with Microsoft Access" manual.
You can use one of the following two methods to work around this behavior.
Method 1Store the procedure in a standard module rather than a class module. This would make the procedure directly accessible from other databases but would require that you convert your class module procedures to standard module procedures.
Method 2Create a function in a standard module in the database where the class module is defined. This function would call the procedure from the class module. Then, you would call this function from a standard module of another database. This allows you to leave your class module procedures as is, but would require that you write a standard procedure for each class module procedure you want to run.
Although its not possible to directly call a procedure defined in a class module of another database from procedures outside of that database, you may notice that it is possible to call them from the Debug window. This is because Visual Basic for Applications relaxes privacy rules and scope restrictions in the Debug window to aid in debugging Visual Basic procedures.
Steps to Reproduce Behavior
