Hello there!
Found your product and tried to evaluate it, but the start is not that easy.
I am getting a FormatException while running the VB.NET Example on page.ExtractText()
It's a VB.NET 2010 Project and I added the 4.0 dlls (also tried the other) and used the Sample.pdf
The excample is modified a bit to be able to select a file.
Please notice that i removed the actual 4.0 Spire.Pdf.dll and the actual Sample2.pdf to meet the 2MB file limitation.
Here is also the Detail Exception showing another error.
