vb.net - Process waiting for input, Get all standard output? - Visual Basic -


i have process ssh's unix server. trying standard output of process if given incorrect credentials. in case, program waits user input correct password (indicating 1 given argument invalid). expected result of following string:

using keyboard-interactive authentication. password:

i know expected because have piped standard output file, ran program in command line. however, running problem whatever reason, standard output give me first line, , hang. prints out using keyboard-interactive authentication not password:

here code:

dim stdoutput = new stringbuilder()  public sub startprocess(processname string, id string, unixserver string, pw string)       dim process process = new process()     process.startinfo.filename = processname     process.startinfo.arguments = "-ssh " & id & "@" & unixserver & " -pw " & pw     process.startinfo.useshellexecute = false     process.startinfo.createnowindow = true     process.startinfo.redirectstandardoutput = true       addhandler process.outputdatarecieved, addressof outputhandler     process.start()     process.beginoutputreadline()     'wait 3 seconds give process chance standard output     process.waitforexit(3000)     console.writeline(stdoutput.tostring())  end sub  public sub outputhandler(process object, outline datareceivedeventargs)     stdoutput.append(outline.data) end sub

this print out using keyboard-interactive authentication. not password: appreciated.

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
