If I use Shell(myapp.exe) how is it different than double clicking on the myapp.exe ?

see the thing is that myapp.exe is written in other language(autoitscript) & it supposed to read contents of 1 .*txt file, but it fails to open that *.txt file if I use Shell(myapp.exe) in vb to start myapp.exe.

Now if I double click on the myapp.exe then it has no problems with reading file contents.

so as you see this is "magic" again....

any questions or ideas what may causing it?
