VB.NET SendKeys ... File Open window

I have a VB.NET application that I am writing.  I need to capture a file by the user and feed that filename into the "file open" of another application.  I am simulating it in this example with notepad.  

The code works until it comes to populating the "open" window in notepad.  

I have tried SendKeys.Send and SendKeys.SendWait

NOTE:  The application (i.e. NOTEPAD) will already be open.

- - - - sample code excerpt - - - -
            openFD.ShowDialog()
            AppActivate("untitled - notepad")
            SendKeys.SendWait("%FO")
           
            ' All is well until this next line.  This line does not work
            SendKeys.SendWait("{quote}" & openFD.FileName & "{quote}{enter}")

Whenever I see send keys I always think - is this really the only way to do it.  It is arguable that sendkeys is not realiable.

If I understand you correctly the user is going to use the windows dialog to open a file.  You would like to intercept or listen to this process and get the file that is being opened and use that information somewhere else?

My program will ask the user for the filename with the Windows dialog to open a file.  That filename (and path) will not be opened, it will be used to copy the file from the network folder to a local folder and open the local file in another program (for now, Notepad).  

I have the first part working.  It asks for a file, copies the file from the network path to the local path.  I am then able to locate the application (in this case Notepad) using "AppActive".  

Now I want to simulate "File...Open" and feed the path/filename, to open the user requested file.

Ok so you have the full path name to the file which is now saved locally.

Your example (which I know is an example) is with notpad.

I would use something like this
System.Diagnostics.Process.Start("notepad.exe", "mydocument.txt")

Open in new window


Why do you need to imitate how a user opens it?

What is the program you really want to open the file in?

The questioner wants to open a file with, in this example notepad.

His example has been answered and one could assume satisfactorily, as he has not questioned it or asked for more assistance for more than a month.
