vbaProject-Compiler

Create a vbaProject.bin file from VBA source files.

VBAProject Class

The vbaProject class contains all the data and metadata that will be used to create the OLE container.

from vbaProjectCompiler.vbaProject import VbaProject
from vbaProjectCompiler.ole_file import OleFile


project = VbaProject()
thisWorkbook = DocModule("ThisWorkbook")
thisWorkbook.addFile(path)
project.addModule(thisWorkbook)

ole_file = OleFile(project)
ole_file.writeFile(".")

The VbaProject class has many layers of customization available. Forexample a librry referenece can be added to the project.

codePage = 0x04E4
codePageName = "cp" + str(codePage)
libidRef = LibidReference(
    "windows",
    "{00020430-0000-0000-C000-000000000046}",
    "2.0",
    "0",
    "C:\\Windows\\System32\\stdole2.tlb",
    "OLE Automation"
)
oleReference = ReferenceRecord(codePageName, "stdole", libidRef)
project.addReference(oleReference)

oleFile Class

Users should not have to interact with the oleFile class. It's job is to extract the data from the vbaProject and turn it into a valid file. This includes deciding which data stream appears where, and applying different views to the models to save the data in the correct formats.

The oleFIle has two parts, a header and a FAT Sector Chain. This FAT chain stores multiple streams of data:

  • Fat Chain Stream
  • Directory Stream
  • Minifat Chain Stream
  • Minifat Data Stream
  • Fat Data Stream

These are all different views of data from the following Models

  • fatChain
  • minifatChain
  • directoryStream
