Hello, I am trying the new msdn 200 express edition but also got VB6, anyone know if there is a way to make a cmd prompt like inside a form, so when running dos apps, it will show the stuff in prompt on your form and not a new cmd prompt?

You would have to get the list of commands from the system. You would also have to define standard IO, which would display input and output.
How might I go about getting the list and defineing the IO. I have no idea. =/
You can get the list of commands in My computer, Properties, Advanced, Environment variables. You also have a lot of IO definitions/samples all over the net. All applications which can be run in a command line, base on standard IO. Are you familiar to, i don't know... C's stdio library?
No, just started, well anyway hmm is there a way even if I run app in standard cmd, to minimize it but not showing in tray or taskbar or the tasklist thing [CTRL+ATL+DEL] ?
Few people have done what you're after. However, you can familiarize yourself with CygWIN, which does something similar (implements terminal into Windows command line), and it's also available in open-source... i think so ;)

I don't know if that ^ will help but I will try it.
This is a good function.. Let me know if you need Win9x support and I'll try to dig up one I used to use..VB Code:
'Purpose : Optionally Synchronously runs a DOS command line and returns the captured screen output. 'Inputs : sCommandLine The DOS command line to run. ' [bShowWindow] If True displays the DOS output window. 'Outputs : Returns the screen output 'Notes : This routine will work only with those program that send their output to ' the standard output device (stdout). ' Windows NT ONLY. 'Revisions : Function ShellExecuteCapture(sCommandLine As String, Optional bShowWindow As Boolean = False, Optional waitFlag As Boolean = True) As String Const clReadBytes As Long = 256, INFINITE As Long = &HFFFFFFFF Const STARTF_USESHOWWINDOW = &H1, STARTF_USESTDHANDLES = &H100& Const SW_HIDE = 0, SW_NORMAL = 1 Const NORMAL_PRIORITY_CLASS = &H20& Const PIPE_CLIENT_END = &H0 'The handle refers to the client end of a named pipe instance. This is the default. Const PIPE_SERVER_END = &H1 'The handle refers to the server end of a named pipe instance. If this value is not specified, the handle refers to the client end of a named pipe instance. Const PIPE_TYPE_BYTE = &H0 'The named pipe is a byte pipe. This is the default. Const PIPE_TYPE_MESSAGE = &H4 'The named pipe is a message pipe.

Note, this will cause your application 'to hang indefinately until this process completes. If waitFlag Then WaitForSingleObject tProcInfo.hProcess, INFINITE 'Determine pipes contents lSuccess = GetNamedPipeInfo(lhwndReadPipe, PIPE_TYPE_BYTE, lPipeOutLen, lPipeInLen, lMaxInst) If lSuccess Then 'Got pipe info, create buffer sBuffer = String(lPipeOutLen, 0) 'Read Output Pipe lSuccess = ReadFile(lhwndReadPipe, sBuffer, lPipeOutLen, lBytesRead, 0&) If lSuccess = 1 Then 'Pipe read successfully ShellExecuteCapture = Left$(sBuffer, lBytesRead) End If End If 'Close handles Call CloseHandle(tProcInfo.hProcess) Call CloseHandle(tProcInfo.hThread) Call CloseHandle(lhwndReadPipe) Call CloseHandle(lhwndWritePipe) End Function
I have no idea what this does.
This allows you to issue CMD console type commands in a procedure, and it returns what would be displayed by the console in the string variable ShellExecuteCapture that you can read and write to controls like text boxes etc or do any other string operations.. It has options to display the console window or execute the process 100% invisibly, and the option to pause your app's execution until the process completes, or continue your app's execution immediately.. (Continuing immediately will cause the function to return only the CMD output that has been written by the time the function exits BTW)
You can just put this in your form or in a module, Add whatever API/Type declarations it demands via errors the first time you execute it and you're good to go..
So if I put this entire function somewhere where would I put it exactly, and how would I get it to work, just type in richtextbox1 and press enter and it will display crap just like CMD?
Oh and I use Windows XP so Would it still work?
You should save yourself alot of grief and hit the tutorials..
The function can be called with 1, 2, or 3 arguments..
It needs the commandline you wish to run obviously..
The other 2 can be added, but if they are not there then they will use the default values.
Defaults:
Dont pop up a visible command window
Wait until process completes before continuing running your app.
egs:
text1.text = ShellExecuteCapture("dir")
text1.text = ShellExecuteCapture("dir",true,false)
text1.text = ShellExecuteCapture("dir",,false)
text1.text = ShellExecuteCapture("dir",true)
This uses text2.text as the command to execute:
text1.text = ShellExecuteCapture(text2.text)
Here are the necessary declarations.. Put these at the top of the module/form you add the function to.. (Putting it in a module makes reusing it in other apps simpler)
VB Code:
Private Type SECURITY_ATTRIBUTES nLength As Long lpSecurityDescriptor As Long bInheritHandle As Long End Type Private Type STARTUPINFO cb As Long lpReserved As Long lpDesktop As Long lpTitle As Long dwX As Long dwY As Long dwXSize As Long dwYSize As Long dwXCountChars As Long dwYCountChars As Long dwFillAttribute As Long dwFlags As Long wShowWindow As Integer cbReserved2 As Integer lpReserved2 As Long hStdInput As Long hStdOutput As Long hStdError As Long End Type Private Type PROCESS_INFORMATION hProcess As Long hThread As Long dwProcessID As Long dwThreadID As Long End Type Private Declare Function CreatePipe Lib "kernel32" (phReadPipe As Long, phWritePipe As Long, lpPipeAttributes As Any, ByVal nSize As Long) As Long Private Declare Function ReadFile Lib "kernel32" (ByVal hFile As Long, ByVal lpBuffer As String, ByVal nNumberOfBytesToRead As Long, lpNumberOfBytesRead As Long, ByVal lpOverlapped As Any) As Long Private Declare Function GetNamedPipeInfo Lib "kernel32" (ByVal hNamedPipe As Long, lType As Long, lLenOutBuf As Long, lLenInBuf As Long, lMaxInstances As Long) As Long Private Declare Function WaitForSingleObject Lib "kernel32" (ByVal hHandle As Long, ByVal dwMilliseconds As Long) As Long Private Declare Function CreateProcessA Lib "kernel32" (ByVal lpApplicationName As Long, ByVal lpCommandLine As String, lpProcessAttributes As Any, lpThreadAttributes As Any, ByVal bInheritHandles As Long, ByVal dwCreationFlags As Long, ByVal lpEnvironment As Long, ByVal lpCurrentDirectory As Long, lpStartupInfo As Any, lpProcessInformation As Any) As Long Private Declare Function CloseHandle Lib "kernel32" (ByVal hObject As Long) As Long Private Const STARTF_USESHOWWINDOW As Long = &H1& Private Const SW_HIDE As Integer = 0&
Yes, Win2K, XP, Server2003 are todays common WINNT's
Okay it seems to compile okay, but it won't show theinfo for "dir" in Text1.Text, any ideas?
Post your code..
Also, add the line:
debug.print ShellExecuteCapture("dir")
right above where you used it in your form code.. What you see returned in the immediate window is what text1.text would be assigned.. Perhaps its a size limitation that another user knows more about than I, or maybe I pooched something.. Who knows..
What in the hell, I think it's doing something because the default text disippears but wont display the dir output info like on CMD prompt when you type dir it shows the dir's but wont show anything for me. in my Text1.Text...
VB Code:
Text1.Text = ShellExecuteCapture("dir", False, True) Debug.Print ShellExecuteCapture("dir")
Help?
