Doc.Close(true) not working as expected.

[Shawn]

Hi, I'm evaluating the trial version of Essential PDF, One of the problems that came up is that when a pdf document is opened and data is drawn on it using Essential PDF, first time it works fine but if i open new document with different parameters the data displayed is overwritten on each other. i.e. the doc still shows the old data with new data as well.

i have followed the recommended format but still no luck.

//Load an existing PDF document
PdfLoadedDocument loadedDocument = new PdfLoadedDocument("Input.pdf");
//To-Do some manipulation
//To-Do some manipulation
//Save the document in file system
loadedDocument.Save("Output.pdf"); 
//Close the document
loadedDocument.Close(true);

see this is the code i'm running;

            string filename = @"Reports\Templates\TestReport.pdf";

            PdfLoadedDocument pdfDoc = new PdfLoadedDocument(filename);

            PdfLoadedPage page = pdfDoc.Pages[0] as PdfLoadedPage;

            PdfGraphics graphics = page.Graphics;

            PdfFont font = new PdfStandardFont(PdfFontFamily.TimesRoman, 10);

            //Candidate Name

            graphics.DrawString("First Name".ToString(), font, PdfBrushes.Black, new PointF(385, 140));

            //Family Name

            graphics.DrawString("Last Name".ToString(), font, PdfBrushes.Black, new PointF(115, 165));

           pdfDoc.Save(filename);

            pdfDoc.Close(true);

            System.Diagnostics.Process.Start(filename);

Hi Shawn, 

Seems like you are opening the PDF document, modify it and save the PDF in the same location as loaded. So the original PDF document is updated with the new content, can you try saving the document in some other location. 

string filename = @"Reports\Templates\TestReport.pdf"; 

PdfLoadedDocument pdfDoc = new PdfLoadedDocument(filename); 

 

pdfDoc.Save(filename); // Instead of this 

pdfDoc.Save(@"Reports\Output\TestReport.pdf"); // try this

yeah it's working now but there is a problem and that is if pdf is already opened another pdf doesn't open when new parameters are supplied.

            string filename = @"Reports\Templates\TestReport.pdf";

            PdfLoadedDocument pdfDoc = new PdfLoadedDocument(filename);

            PdfLoadedPage page = pdfDoc.Pages[0] as PdfLoadedPage;

            PdfGraphics graphics = page.Graphics;

            PdfFont font = new PdfStandardFont(PdfFontFamily.TimesRoman, 10);

            //Candidate Name

            graphics.DrawString("First Name".ToString(), font, PdfBrushes.Black, new PointF(385, 140));

            //Family Name

            graphics.DrawString("Last Name".ToString(), font, PdfBrushes.Black, new PointF(115, 165));

            pdfDoc.Save(@"Reports\Output\TestReport.pdf")

            pdfDoc.Close(true);

            System.Diagnostics.Process.Start(@"Reports\Output\TestReport.pdf");

Hi Shawn, 

Yes, this is the general behavior of the C#, as the file is being open in another program I can not be resaved. You may save the output PDF with different name to ignore this exception.

Hi Karthikeyan, I have tried to save it with different name but still same problem coming. Any other solution?

            string filename = @"Reports\Templates\TestReport.pdf";

            PdfLoadedDocument pdfDoc = new PdfLoadedDocument(filename);

            PdfLoadedPage page = pdfDoc.Pages[0] as PdfLoadedPage;

            PdfGraphics graphics = page.Graphics;

            PdfFont font = new PdfStandardFont(PdfFontFamily.TimesRoman, 10);

            //Candidate Name

            graphics.DrawString("First Name".ToString(), font, PdfBrushes.Black, new PointF(385, 140));

            //Family Name

            graphics.DrawString("Last Name".ToString(), font, PdfBrushes.Black, new PointF(115, 165));

            pdfDoc.Save(@"Reports\Output\TempReport.pdf")

            pdfDoc.Close(true);

            System.Diagnostics.Process.Start(@"Reports\Output\TempReport.pdf");

Hi Shawn, 

Please use the below code snippet to achieve your requirement. 

string filename = @"Reports\Templates\TestReport.pdf"; 

PdfLoadedDocument pdfDoc = new PdfLoadedDocument(filename); 

PdfLoadedPage page = pdfDoc.Pages[0] as PdfLoadedPage; 

PdfGraphics graphics = page.Graphics; 

PdfFont font = new PdfStandardFont(PdfFontFamily.TimesRoman, 10); 

 

//Candidate Name 

graphics.DrawString("First Name".ToString(), font, PdfBrushes.Black, new PointF(385, 140)); 

 

//Family Name 

graphics.DrawString("Last Name".ToString(), font, PdfBrushes.Black, new PointF(115, 165)); 

 

string fileName = @"Reports\Output\TempReport_" + Guid.NewGuid() + ".pdf"; 

pdfDoc.Save(fileName) 

pdfDoc.Close(true); 

System.Diagnostics.Process.Start(fileName);

Hi, i'm receiving this error after implementing your solution.

The process cannot access the file 'Project\bin\Debug\Reports\Output\TempReport_9fad6fca-6c74-404d-b1b3-e9fc7ba844cf.pdf' because it is being used by another process.
