     This is a DEMO Application on Using my FileMapping VB Class Module to Simulate the use of File Mapping APIs Used in Visual C++ and Win32 Assembly, Why in Visual Basic, Why Not? FileMapping Class Module ======================== Tired of using the traditional Visual Basic File Handling Routines, or even FileSystemObject failed to read to a file byte-by-byte, or you want to Access a File Using Pointers for Better Scalability Performance, while Some Anti-Virus Blocks the use of very useful FileSystemObject, File Mapping Functions comes into a handy set of routines just waiting for you to use them, and take note, we people as Visual C++ and Win32 Assembly uses this functions, because we dont have easy macros. Why use easy routines, and limiting your performance, use File Mapping, thats the only way!!! yup, Visual Basic doesn't support Pointer Variables, but there is a CopyMemory "RtlMoveMemory" to do the same effects (a little slower than the real pointers but that will do just fine) Included in this ZIP file is my Class Module to perform FileMapping and a demo Project on how to use the File Mapping by Traversing to an Executable format and checks whether it is a valid Win32 Portable Executable Format and finally checks what type of PE it is, PE32 or PE64 ======================================================================== This code checks for a valid PE Executable Format To understand this Application, you need to consult your nearest PE Documentation. Win32 Assembly Codes are included in Comments are 100% working on TASM32 Compiler, Created by: Chris Vega []

Note: Due to the size or complexity of this submission, the author has submitted it as a .zip file to shorten your download time. Afterdownloading it, you will need a program like Winzip to decompress it.Virus note:All files are scanned once-a-day by Planet Source Code for viruses, but new viruses come out every day, so no prevention program can catch 100% of them. For your own safety, please:
  1. Re-scan downloaded files using your personal virus checker before using it.
  2. NEVER, EVER run compiled files (.exe's, .ocx's, .dll's etc.)--only run source code.
  3. Scan the source code with Minnow's Project Scanner

If you don't have a virus scanner, you can get one at many places on the net
