Example:

!notepad C:\Program Files\MyFolder\textFile.txt

Just replace that path with your own.

Okj that works but know i want to pick a .sin file out of a load window. You know how to do that? i tried

m = uigetfile('*.sin','Select the .sin-file');
!notepad m

but that didnt work! I need something to read out the file and then to open it. Thx a lot

[Paulo Silva]

eval(['!notepad ' m])

[Paulo Silva]

The way you call uigetfile is wrong

[FileName,PathName] = uigetfile('*.sin','Select the .sin-file')

eval(['!notepad ' PathName FileName])

[Paulo Silva]

And another way for those who hate the eval function

system(['notepad ' PathName FileName])

Okj thx so much paulo,

    [FileName,PathName] = uigetfile('*.sin','Select the .sin-file') 
    eval(['!notepad ' PathName FileName])

works, but when the load window opens and if i click on annulate, there opens an empty notepad window and thats not the goal :) hope you have something to fix that.

[Paulo Silva]

[FileName,PathName] = uigetfile('*.sin','Select the .sin-file')

if ischar(FileName)

%disp('file selected')

eval(['!notepad ' PathName FileName])

else

%disp('user canceled')

end
