Hi - we are getting this error inconsistently. This is running on web farm environment. We are unable to reproduce until issue occurs then every PDF export we attempt on the website will get this error going forward. Rebooting the server that hosts IIS will resolve this issue which is our current workaround.
Thanks,
Chris
using (MemoryStream stream = new MemoryStream())
{
***ISSUE HERE*** -> HtmlToPdfResult pdfResult = HtmlToPdf.ConvertHtml(report_html_string, stream);
// if file already exists on server delete before recreating
if (System.IO.File.Exists(filePath))
System.IO.File.Delete(filePath);
using (var fileStream = System.IO.File.Create(filePath))
{
pdfResult.PdfDocument.Save(fileStream);
}
}

Hi, Error code 5 is access denied. This usually occurs when you have another application/service that locks the file. You can try to enable EO worker process and see if it resolves the issue for you: https://www.essentialobjects.com/doc/common/eowp.aspxFor an ASP.NET application, you can copy eowp.exe into your application's bin folder, or place it somewhere else on your system but your application has read/execute permission to it. If you place it at a different location, you would need to call this method in your application to inform our library where it is: https://www.essentialobjects.com/doc/eo.base.runtime.initworkerprocessexecutable.aspxPlease let us know if this resolves the issue for you. Thanks!
