[Gambas-user] Send data to the process

[Brian G]

Here is a short set that will return what you wrote 
background process: 
' Gambas module file 

Public AllDone As Boolean = False 

Public Sub Main() 
While Not AllDone 
Wait 0.01 
Wend 
Quit 0 
Catch 
Quit 0 
End 

Public Sub Application_read() 
Dim readline As String = "" 
While Lof(Last) 
readline &= Read #Last, -254 
Wend 
If readline == "quit" Then 
AllDone = True 
Else 
Print Eval(readline) 
Flush 
Endif 
Catch 
Print Error.Text 
Flush 
End 
******************************************************* 
The forground process: 

Public MyApp As Process 
Public Sub Main() 
Dim readline As String 
MyApp = Exec [User.Home &/ "bin/AppSendRecvBG.gambas"] For Input Output As "BgApp" 
While MyApp.state = Process.Running 
Line Input readline 
Print "Read :";; readline 
Print #MyApp, readline 
Flush #MyApp 
Wait 0.01 
Wend 
Quit 0 
End 

Public Sub BgApp_read() 

Dim readline As String 
readline = "" 
While Lof(Last) 
readline &= Read #Last, -254 
Wend 
Print readline 
End 
*********************************************************
