Hi,

I'm getting an error

java.lang.Exception: CallByName 'waitFor' failed!



, when using the line


pProcess.waitFor()


, in the code below:




Dim sOutput As String
Dim sFileName As String
Dim sFileSize As String
Dim sWildCard As String
Dim sCurrentOutput As String
' Dim pProcess As #java#lang#Runtime 'Produces a compile error, when getRuntime().exec is used.
' Compile error... Type mismatch. Found 'java/lang/Process' but 'java/lang/Runtime' is required!

Dim pProcess As Variant
Dim brReader As #java#io#BufferedReader

Dim sLine As String

pProcess = #Java#lang#Runtime.getRuntime().exec( "cmd /c dir" )
pProcess.waitFor()

brReader = New BufferedReader( New #java#io#InputStreamReader( pProcess.getInputStream() ) )
sLine = brReader.readLine()

Stop
Do While Not (sLine = Null)
frmIDMPrompt.txtOutput.AppendText( sLine + vbCrLf )
sLine = brReader.readLine()
Loop

If you modify the pProcess declaration, it won't compile at all:

Dim pProcess As Variant = New #java#lang#Runtime

Got it. For anyone who can use this:



Dim pProcess As #java#lang#Process
Dim brReader As #java#io#BufferedReader

Dim sLine As String

pProcess = #java#lang#Runtime.getRuntime().exec( "cmd /c dir" )
pProcess.waitFor()

brReader = New BufferedReader( New #java#io#InputStreamReader( pProcess.getInputStream() ) )
sLine = brReader.readLine()

Do While Not (sLine = Null)
frmIDMPrompt.txtOutput.AppendText( sLine + vbCrLf )
sLine = brReader.readLine()
Loop

In Jabaco you can additional use the Shell() command:

Thanks, theuserbl. Can you also redirect standard output to a Text Box, if you use Shell?
