Merge various files into one searchable PDF (LEADTOOLS 19)

The attached Visual Studio 2017 C# project has been updated to use LEADTOOLS 19. The original project can be found here

This project will allow you to select any files support by LEADTOOLS and merge them into a single, searchable PDF.

To run this project, please extract it to the following directory:
C:\LEADTOOLS 19\Examples\posts\t10631

You use the demo as follows:
- First you select multiple files (including DOC, DOCX, PPT, PPTX, XLS, XLSX, RTF, PDF, TIF, Multipaged TIF, PNG, etc). Keep in mind the order the files are listed in, is the order they will be merged into the final PDF.
- Next you specify where to place the resulting file.
- Finally you press the "convert" button.

The program flow is as follows:
Once you press the "convert" button, the application queries each file looking for PDF files. If a PDF is found, it determines if the file is already searchable. If not, then it marked to be OCRed.
Once all files are marked to be OCR, they are recognized and saved in temporary files. Once all files have been recognized, the temporary files are converted to PDF. Then all PDF's are merged into one final PDF.


UPDATE: This is an updated project including configurations for LEADTOOLS 18, 19, & 20. To run this project, please extract it to the following directory:
<LEADTOOLS installation>\Examples\posts\t12276\
