I want to read a specific line from the text file using VBScript.
I have explored Read and ReadLine methods but I can't able to read only specific line from text file. (I have 1000 of line but I want to read only 99 or 200 or 500 line only)
The question may be similar to the questions those duplicate hunters pointed to, but the answers are - for different reasons - of no use. A good answer could be build from one answer to the completely different question here.
Now to the answer:
Use a .SkipLine loop to read to the line before you are interested in and get it using .ReadLine.

I am working on some code that has paths that look like this:
"pack://application:,,,/FOO.Bar.Baz;component/Gorp/bazzle.xaml"
What do the 3 commas mean, and what is this path referencing?
Typically they are placeholders for parameters that were not supplied. It usually means ... "use the default values" for those parameters.
