![]() Programming In The VBA Editor. Programming The VBA Editor. This page describes how to write code that modifies or reads other VBA code. You can write code in VBA that reads or modifies other VBA projects, modules, or procedures. This is called. extensibility because extends the editor - - you can use VBA code to create new VBA code. You can use these features to write custom procedures that create, change, or delete VBA modules and code. In order to use the code on this page in your projects, you must change two settings. First, you need to set an reference to the VBA Extensibility library. The library contains the definitions. VBProject. In the VBA editor, go the the Tools menu and choose References. In that. dialog, scroll down to and check the entry for Microsoft Visual Basic For Applications Extensibility 5.
If you do. not set this reference, you will receive a User- defined type not defined compiler error. Next, you need to enable programmatic access to the VBA Project. In Excel 2. 00. 3 and earlier, go the Tools menu. Excel, not in the VBA editor), choose Macros and then the Security item. In that dialog, click on the. Trusted Publishers tab and check the Trust access to the Visual Basic Project setting. In Excel 2. 00. 7, click the Developer item on the main Ribbon and then click the Macro Security item in. Code panel. In that dialog, choose Macro Settings and check the Trust access to the VBA project. The VBA Project that you are going to change with these procedures must be unlocked. There is no programmatic way to. VBA project (other than using Send. Keys). If the project is locked, you must manually. Otherwise, the procedures will not work.

This is not. a comprehensive list, but will be sufficient for the tasks at hand. VBIDEThe VBIDE is the object library that defines all the objects and values that make up VBProject and the. Visual Basic Editor. You must reference this library to use the VBA Extensibility objects. To add this. reference, open the VBA editor, open your VBProject in the editor, and go to the Tools menu. There, choose References. In the References dialog, scroll down to Microsoft Visual Basic for Applications Extensibility 5. You can add the reference programmatically with code like. This. Workbook. VBProject. References. Add. From. Guid _. GUID: ="{0. E1. 57- 0. 00. 0- 0. C0. 00- 0. 00. 00. Major: =5, Minor: =3. The VBE refers to the Visual Basic Editor, which includes all the windows and projects that make up the. VBProject. A VBProject contains all the code modules and components of a single workbook. One workbook has exactly one. VBProject. The VBProject is made up of 1 or more VBComponent objects. VBComponent. A VBComponent is one object within the VBProject. A. VBComponent is a regular code module, a User. Form, a class module, any one of the Sheet modules, or the This. Workbook. module (together, the Sheet modules and the This. Workbook module are called. Document Type modules). A VBComponent is of one of the following types, identified by the Type. The following constants are used to identify the Type. The numeric value of each constant. Class. Module (2): A class module to create your own objects. See. Class Modules for details about classes and objects. Document (1. 00): One of the Sheet modules or the This. Workbook. module. MSForm (3): A User. Form. The visual component of a User. Form in the VBA. Editor is called a Designer. Std. Module (1): A regular code module. Most of the procedures on this. Code. Module. A Code. Module is the VBA source code of a VBComponent. You use the Code. Module. object to access the code associated with a VBComponent. A VBComponent has. Code. Module which contains all the code for that component. Code. Pane. A Code. Pane is an open editing window of a Code. Module. When you are typing code. Code. Pane. The code below illustrate various ways to reference Extensibility objects. Dim VBAEditor As VBIDE. VBE. Dim VBProj As VBIDE. VBProject. Dim VBComp As VBIDE. VBComponent. Dim Code. Mod As VBIDE. Code. Module. Set VBAEditor = Application. VBE. Set VBProj = VBAEditor. Active. VBProject. Set VBProj = Application. Workbooks("Book. 1. VBProject. Set VBComp = Active. Workbook. VBProject. VBComponents("Module. Set VBComp = VBProj. VBComponents("Module. Set Code. Mod = Active. Workbook. VBProject. VBComponents("Module. Code. Module. Set Code. Mod = VBComp. Code. Module. In the code and descriptions on this page, the term Procedure means a Sub. Function, Property Get, Property Let. Property Set procedure. The Extensibility library defines four procedures types, identified. The numeric value of each constant is shown within parentheses. Get (3). A Property Get procedure. Let (1). A Property Let procedure. Set (2). A Property Set procedure. Proc (0). A Sub or Function procedure. The rest of this page describes various procedures that modify the various objects of a VBProject. The VBA editor is said to be "in sync" if the Active. VBProject is the same as the. VBProject that contains the Active. Code. Pane. If you have two or more projects open. VBA editor, it is possible to have an active code pane open from Project. Project. 2. selected in the Project Explorer window. In this case, the Application. VBE. Active. VBProject is the project. Project window, while Application. VBE. Active. Code. Pane is a different project. Application. VBE. Active. Code. Pane. Code. Module. Parent. Collection. Parent. You can test whether the editor in in sync with code like the following. Function Is. Editor. In. Sync() As Boolean. With Application. VBE. Is. Editor. In. Sync = . Active. VBProject Is _. Active. Code. Pane. Code. Module. Parent. Collection. Parent. You can force synchronization with code like the following. This will set the. Active. VBProject to the project associated with the. Active. Code. Pane. Sub Sync. VBAEditor(). With Application. VBE. If Not . Active. Code. Pane Is Nothing Then. Set . Active. VBProject = . Active. Code. Pane. Code. Module. Parent. Collection. Parent. This code will add new code module named New. Module to the VBProject of the active workbook. The type of. VBComponent is specified by the value of the parameter passed to the Add method. Sub Add. Module. To. Project(). Dim VBProj As VBIDE. VBProject. Dim VBComp As VBIDE. VBComponent. Set VBProj = Active. Workbook. VBProject. Set VBComp = VBProj. VBComponents. Add(vbext_ct_Std. Module). VBComp. Name = "New. Module". Creating a procedure via VBA code is really quite simple. Build up a text string of the code, using vb. Cr. Lf to. create new lines, and then insert that text with the Insert. Lines method, passing to it the line number. The following code will add a simple "Hello World" procedure named Say. Hello to the end of the module named. Sub Add. Procedure. To. Module(). Dim VBProj As VBIDE. VBProject. Dim VBComp As VBIDE. VBComponent. Dim Code. Mod As VBIDE. Code. Module. Dim Line. Num As Long. Const DQUOTE = """". Set VBProj = Active. Workbook. VBProject. Set VBComp = VBProj. VBComponents("Module. Set Code. Mod = VBComp. Code. Module. With Code. Mod. Line. Num = . Count. Of. Lines + 1. Insert. Lines Line. Num, "Public Sub Say. Hello()". Line. Num = Line. Num + 1. . Insert. Lines Line. Num, " Msg. Box " & DQUOTE & "Hello World" & DQUOTE. Line. Num = Line. Num + 1. . Insert. Lines Line. Num, "End Sub". End With. You can also build up a String variable with the content of the procedure and insert that string with one call to Insert. Lines. For example. Dim Code. Pan As VBIDE. Code. Module. Dim S As String. Set Code. Pan = This. Select or Open a file in VBA with file dialog. In a recent project, I was tasked with designing a program in Access where an end user could import a spreadsheet, run a sub routine in VBA and export the results. As part of the user experience, I wanted the end user to be able to select the input spreadsheet with the file dialog tool. UPDATE 0. 5/2. 2/2. The function below contains an error handler and works well if your input has the potential to throw an error. For simplicity- sake, I have included a more compact version (short- circuited) under this one: 1.

Please note, you still need to include a reference to the Microsoft Office 1. Object Library. I have tried every trick I could find to implement late binding (bind in code without reference). I have found that you simply can’t implement without reference (early binding). If anyone out there can prove me wrong on this, please do comment.

Since VBA doesn’t do objects/arrays like other programming languages, it is difficult to make the function return an array or object. So, I built my example in a Public Sub and marked up the area that returns selected filenames with a loop. My assumption is that if you need to select multiple files in VBA, you will probably have an idea for how to implement. If you run into a wall, add a comment and we can work on a solution.
