I have been looking into this for several hours now. Now, don't get me wrong; I am not an expert, but here is what I found.
1. See the MS article referenced below for a discussion of how Windows launches the default browser.
2. You can use the launch mnemonic, or ShellExecute mnemonic from LUN 0, From a background program you can only use the ShellExcecute mnemonic to the system gateway.
3. If you use launch or shellExecute on lun 0, you should input the result string even if you do not wish to examine it.
4. If you launch the document, not the program, you will get multiple documents in the same window.
5. That pause between launches seems to be important. Maybe it gives Windows a chance to find the application. Without it, especially using Firefox as the default browser, gives "mixed" results.
6. To launch a new window for each document, do the shell execute of the executable, passing the path as an argument to it.
7. Firefox does not like DDE for some reason. Try editing the open action for the HTML file type and unchecking "Use DDE".
Here is my test program. Try changing the comments and see what results you get. With this limited testing, it seems that IE7 is more consistent than Firefox.
length 80 & local a$ path$
print (et)
path$ = 'd:\comet\COS\HTML1.HTM'
Gosub Launchit
pause(18) ! this makes a difference
path$ = 'd:\comet\COS\HTML2.HTM'
Gosub Launchit
stopLaunchIt:
!Print (0) (Launch=path$)
!Print (0) (ShellExecute="open",path$,"","",1)
!Print (0) (ShellExecute="","iexplore",path$,"",1)
Print (0) (ShellExecute="","C:\Program Files\Mozilla Firefox\firefox.exe",path$,"",1)
input a$ ! need to input result string for lun 0 activity!Close (20)
!Open (20) "X00"
!Print (20) (ShellExecute="Open",path$,"","",1) ! opens default browser in a single window
!Print (20) (ShellExecute="","iexplore",path$,"",1) ! opens each in a new window
!Close (20)
