My program has the pdf viewer to view PDF file. When I deploy / install my application to users. Some users can view the pdf content and some users display blank page only without prompt any error message. Why ? Any missing ? Please advise.
Are you able to open the PDF in another PDF Reader? What about the Edge Chromium browser? TAdvPDFViewer is a component that wraps Microsoft APIs, so all we do is use the APIs and then render the result. If something is going wrong, then it's more than likely an issue with the PDF, the operating system or incorrect WinRT libraries / version. You might want to check that and compare it with an operating system where everything works fine. If the PDF file does not contain sensitive information, you can send it to us so we can investigate here. If you generated the PDF yourself, it could be possible that the culprit is the engine that you generated the PDF with.
I can open this PDF file by Adobe reader so it is not the file corrupted.
Some user need to admin right to install my program. after installed, I cannot view the pdf content via my program with TAdvPdf viewer. However, if I switch to another user to login then I run the same program, then it can display pdf content. so strange..
This is a big issue or problem for me to deploy application to client as the PDF feature is very important so hope you can advise which modules are missing and cause this problem.
I fixed and this is not relate to this tools. As I use the network drive G: for the pdf file path so some users had not map the network drive so it cannot open pdf file. now I changed it to use the absolute path e.g. '\192.168.1.2\xyz\abc.pdf' instead of G:\abc.pdf
