| | Re: Compare PDF documents using C# You can do it, but you will have to program different formats in unless you are just comparing bits. A line in code can easily be compared by walking the document and comparing lines. But this is code in each of the apps you are talking about. Let's take word for an example: To compare, you will have to read lines as Word lines, not as lines in the file created by Word. Now, if you are using Word 2007, you can actually compare XML, as that is the storage mechanism (also true for Excel 2007). Assuming you are talking older versions of Word, you then have to stoke up the Word libraries to read through the lines. PDF presents the same problem, as what you see in the final document (viewed in Reader, for example) is not what you will see if you open this in notepad. -- Gregory A.

| | Re: Compare PDF documents using C# Understood your point, do you have any example for the same? Are there any legal issue if we use the PDF, Word, Excel library in .Net application? -- Thanks, PS "Cowboy (Gregory A.
