របៀប Import និង Export កូដ VBA


Import and Export VBA code

Copy the code in a Standard module of your workbook, if you just started with VBA see this page.
Where do I paste the code that I find on the internet
On this page you find some basic VBA code to Import and Export VBA code in Excel for Windows.
You can use it to import modules/userforms to other Excel files or to update the code in other Excel files.
Note: This example not Export/Import the code in sheet modules and from the Thisworkbook module.

Tip: Check out also the two links in the "More Information" part of this page.

The Export macro will export every module(.bas),class module(.cls) and userfom(.frm, .frx) from the ActiveWorkbook to a folder named "VBAProjectFiles" in your Documents folder.
Note: never rename these files manual because the name of the file is not the module name that you
see after you import the code into another Excel workbook.

If you open for example a module file (.bas) in Notepad you see this line of metadata at the top
Attribute VB_Name = "TheNameYouWant"
This is the name that the Module have when you import it into another workbook.

If you edit the name of a module in the properties of the module it will update this line nicely. So if you see names that are not correct after your Export check out this metadata line first. If this line is missing it will use the default Module1, Module2, .......

How does it work ?

1: Open the file with the code from this page
2: Open/Activate the file with the modules you want to export
3: Run the ExportModules macro
4: Note: If you look in the VBAProjectFiles folder you see the files now
5: Open/Activate the workbook where you want to add the modules to
6: Run the ImportModules macro (It delete all existing modules/userforms from this Workbook first)
7: Done

The VBA code

Copy every macro and function below into a Standard module of a new workbook and save this Import-Export file as xls or xlsm.
