hi, I have a pdf editor software which opens pdf files in edit mode. I am opening a pdf file through this software in my code. The code is as follows: Process.Start(Application.StartupPath.Substring(0, Application.StartupPath.ToString().IndexOf("Eviction")) + "PDF Editor 2\\PDFEdit.exe", "F:\\Covenant.pdf"); But, I want to pass some data to be displayed in the pdf file. This software allows to insert some textboxes(with name given to each textbox) in the pdf file and save them. So, when I open this pdf file through my code, I want some values to be displayed in these textboxes. Can anyone help me out? Thanks in advance. Jasmy

Thank you for giving the answer(for your clear explanation). But, my problem was to do this through code in tha application. I have the solution now. Just use the following line of code: Process.Start("Path of the exe file of the software", "Path of the file to be opened"); [In Windows Application using C#). Jasmy

I have a pdfeditor software installed in my system. I have an application(.Net Windows application) where I need to open a pdf file through that software. Can anyone help me out? Thanks in advance. Jasmy
