.Exe being executed only by another app *Resolved*

[Elminster]

Hey guys!

For example lets say that I have two files: test1.exe and test2.exe.

I would like to make the test2.exe only run if its called by test1.exe...

So, if I click twice in test2.exe nothing will happen... Only if the test1.exe call it using the shellexecute or something similar...

Is there a way to do that?

Thanks in advance,

Elminster

Probably the easiest way would be to have test2.exe only run if it's parameters are a certain 'secret' value.
In text1.exe you'd do something like ShellExecute "text2.exe -password". -password would be accessed using the command$ variable in test2.exe (i *think*).

Yeah you could do that quite easily. Create a common txt file that both test1.exe and test2.exe are linked too. Then say test2 was ready to be activated then test1 would write a password or something to the txt file, so that when test2 was clicked it would access that txt file check the password if the password was right then run. Yuo would then have to get test2 to delete the txt file if the password was correct so that you could start over again.

there is a better way but its too good to tell ...lol

test1.exe

Private Sub Command1_Click()
dim open
Open "c:\password.txt" For Output As #1
Print #1, "password"
Close #1
Shellex "c:\test1.exe"
End Sub

test2.exe

Private Sub Form_Initialize()
Me.Hide
Open "c:\password.txt" For Input As #1
Input #1, getpassword
Close #1
If getpassword = "password" Then
Form1.Show
Kill "c:\password.txt"
Else
GoTo End1
End If
End1:
End Sub

Thats sounds pretty good!
I would never think in something like this.
Its simple and should work really well!

Really thanks guys!

I would go with what SLH suggested. here's the full code:

in test1:

Shell "text2.exe -password".

in startup of test2:

If Trim(Command) <> "-password" Then
  'the password is wrong, so dont run
  Unload Me       '(you only need this line if this is run in a form)
  Exit Sub
End If

Wow, I like that one too...

I think its more secure. I will try that.

Really thanks,
