expression.OpenModule(ModuleName, ProcedureName)
expression Required. An expression that returns one of the objects in the Applies To list.
ModuleName Optional Variant. A string expression that's the valid name of the Visual Basic module you want to open. If you leave this argument blank, Microsoft Access searches all the standard modules in the database for the procedure you selected with the procedurename argument and opens the module containing the procedure to that procedure. If you execute Visual Basic code containing the OpenModule method in a library database, Microsoft Access looks for the module with this name first in the library database, then in the current database.
ProcedureName Optional Variant. A string expression that's the valid name for the procedure you want to open the module to. If you leave this argument blank, the module opens to the Declarations section.
Remarks
You must include at least one of the two OpenModule action arguments. If you enter a value for both arguments, Microsoft Access opens the specified module at the specified procedure.
If you leave the procedurename argument blank, don't use a comma following the modulename argument.
Example
The following example opens the Utility Functions module to the IsLoaded( ) Function procedure:
DoCmd.OpenModule "Utility Functions", "IsLoaded"
