command prompt

[je_nickp]

وقتی شما دستوری تو command prompt می نویسید واجرا می کنید یه نوشته هایی بعد از اجرا روی صفحه ظاهر می شود (خروجی دستور) . چه جوری میشه اون خروجی ها رو به دست آورد؟

سلام.
یک Command Button و دو تا Text Box رو فرمت بذار و خاصیت Multiline تکست باکس دومی رو به True‌تنظیم کن.
حالا کد زیر رو در فرم کپی کن:


Option Explicit

Private Declare Function ReadFile Lib "kernel32" (ByVal hFile As Long, lpBuffer As Any, ByVal nNumberOfBytesToRead As Long, lpNumberOfBytesRead As Long, lpOverlapped As Any) As Long

pa.lpSecurityDescriptor = 0
pa.bInheritHandle = True

pra.nLength = Len(pra)

If CreatePipe(hRead, hWrite, pa, 0) <> 0 Then
sui.cb = Len(sui)
GetStartupInfo sui
sui.hStdOutput = hWrite
sui.hStdError = hWrite
sui.dwFlags = STARTF_USESHOWWINDOW Or STARTF_USESTDHANDLES
sui.wShowWindow = SW_HIDE

DoEvents
Else
CloseHandle pi.hThread
CloseHandle pi.hProcess
Exit Do
End If
CloseHandle hWrite
Loop
CloseHandle hRead
End If
End If
End Sub


یعنی با این کدها می تونی دستورات Dos رو از توی برنامه خودت اجرا کنی و خروجی دستورات رو در یک Text Box ببینی.
نکته: اجرای این کدها برای بعضی دستورات در ویندوزهای 95، 98 و ME ممکنه به قفل کردن سیستم منجر بشه.
موفق باشید.

جالب بود ولی خیلی جاهی گیر داره
مثلا برای همین ping
ping google.com -t
Ping request could not find host google.com. Please check the name and try again.

در حالی که خود cmd نتایجش متفاوته
میشه گفت نتایج را در یک فایل بریزد و شما فایل را بخوانید
مثل
[/code]ping google.com >C:\test.txt[code]
