how to open notepad file from labview?

[raghavendra]

My application requires a txt file to be opened and displayed.
the problem is, we are able to launch the notepad using "systemexec.vi".
but we want to launch the notepad with the appropraite file opened along with
launching of notepad.exe.

we don't want the user to interact with the "open file dialouge box" of
the note pad appliation.we just want the user to view directly the
required txt file.

how can we achive this?

Hi Rags

notepad accept commad line argumets so you can call it passing arguments such as the file name to open.
Try this "notepad.exe " at the command line input of the system exec function.

Hi,
All you have to do is use the "systemexe.vi" and generate a path like for example :- notepad.exe "C:\Documents and Settings\viveks\Desktop\ftp.txt" this is given to the command line argument in systemexe.vi this will do your job.

If you only want to display a text file you can load it and use a string indicator inside Labview. So your user will never have to deal with notepad.exe (as he can access the menu of notepad anyway...).

Hi

I am not able to open the txt file, my text file is palced
at the path mentioned below "C:\Documents and Settings\raghavendra\Desktop\report.txt".

if i pass the above mentioned path to the command line argument in systemexec.vi
it generates error.

i have no problem opening "notepad.exe".....but iwant the report.txt to
be opened when i open notepad.

Hello Rags,

you're not able to open the report? Why? Can notepad open the text file? Can Labview open the textfile?
Why do you want to display the text using notepad?

Hi,
Your command should be .... notepad.exe "C:\Documents and Settings\raghavendra\Desktop\report.txt" ... not only the path,try this it shall work.
