How to load PDF document into EdgePDF ASP.NET PDF Editor

To run the following demo code, please do the following steps:

1. Create and add the follow sample documents to folder "c:\temp\"
   • pdf-1.pdf
   • tiff-1.tif
   • word-1.docx
   • excel-1.xlsx
   • powerpoint-1.pptx
   • jpeg-1.jpg
   • text-1.txt
2. Make sure IIS application (User: IIS_IUSRS) has the read and write rights to the folder "temp“, and all files inside.

The following guide will help to setup a demo project, which allows you to open a file (pdf, word, excel, powerpoint, tiff, jpeg, text) located under your server file system "C:/temp/", through url:
http://localhost:9090/?yourtarget=/1.pdf.

Next one will allow you to define a new command in EdgePDF toolbar. And you can save modified pdf file to original file location "C:/temp/1.pdf"

Here are the details:

• Setup EdgePDF demo project in IIS.
• In /RasterEdge_Resource_Files/UserCommandProcessHandler.ashx method "FileProcess()"

            else if (!string.IsNullOrEmpty(request.QueryString["yourtarget"]))
            {

                // load file from your target
                String docid = request.QueryString["yourtarget"];                
                if (docid == null) docid = "0";
                byte[] dataBytes = System.IO.File.ReadAllBytes(@"C:\\temp\" + docid);
                String fileName = docid;               
                webDoc = REProcessControl.PageLoadFile(request, this.Manager, dataBytes, fileName);

• Now you navigate to "http://localhost/?yourtarget={your file location key, such as '/word-1.docx'}" to open file in EdgePDF editor.
