Getting open with program

• Find at: PropertiesDotNet.vb#L6
• And: PropertiesDotNet.vb#L147
• http://www.vb-helper.com/howto_get_associated_program.html
• The page above is in VB6 however, so I needed to convert it (manually) to VB.Net. Also, the most important line, the Function FindExecutable Lib "shell32.dll", is chopped off the sample you see on the page, so you have to download the zip to get that.

NTFS Compression

• Find at: CompressReport.vb#L59
• And: CompressReport.vb#L68
• http://www.thescarms.com/dotnet/NTFSCompress.aspx
• Original code from above link has been copied, un-modified, to NTFSCompressOriginalCode.cs
• I have edited it so it can be compiled: NTFSCompressConvertable.cs
• Then I converted it to VB.Net: NTFSCompressConverted.vb
• MSDN Info (for decompression value): https://msdn.microsoft.com/en-us/library/windows/desktop/aa364592(v=vs.85).aspx

Hash Generating

• Find at: Hashes.vb#L405
• Basic Hashing: http://us.informatiweb.net/programmation/36--generate-hashes-md5-sha-1-and-sha-256-of-a-file.html
• Hashing with progress reporting: http://www.infinitec.de/post/2007/06/09/Displaying-progress-updates-when-hashing-large-files.aspx
• Since the code on the page above is in C#, I converted it to VB.Net:
