Visual Basic Command Protocol

Hello, I am currently writing an improved, aesthetically and practically, clone of MS-DOS. You might have seen another post about the same subject by Kgenis, as we are both working on it together, only difference is I only started learning VB last night... well here goes.

We currently have a few commands scripted that use two arguements, such as "Rm Driveletter\Path.to.file" then VB checks executes the DelTree command followed by the specified file. But now we need to make another set of commands that use just one arguement, such as a 'HELP' command that prints all the commands and there uses or a 'logoff' command, that logs the current user off the computer.

In summary:
The user types a command, e.g. 'help' into the texbox.
VB then takes this command and executes what we want it to do, in this case, using AddLine to print all of the commands and there uses to the screen.

Matt is not currently around so I can't contact him on the issue, and I would like it done by tomorrw, so any help is greatly appreciated. I appologise for the small amount of available points to hand out.

Hope this helps:

Option Compare Text 'add this line to the top

Sub Command1_Click()
Dim strTmp As String, arrStr() As String
strTmp = Text1.Text
arrStr = Split(strTmp, " ")
Select Case arrStr(0)
Case "help"
PrintHelpToScreen
Case "logoff"
CallCodeToLogoffUser
Case "rm"
RemoveFolder arrStr(1)
End Selecr
End Sub

Here is a link to some of the current source:

All help is much appreciated, thank you.

Well it should work if you comment (add ' before it) this line:

If Len(tmpArgument) = 0 Then GoTo Err

No that doesn't work...

It also needs that in for it too work, there needs to be a second function or something that checks to see if help or other single arguement commands are typed and deals with them appropriately.

DarkoLord

Okay, try this then:

Sub Command1_Click()
Dim strTmp As String, arrStr() As String
strTmp = Text1.Text
arrStr = Split(strTmp, " ")
Select Case Ubound(arrStr)
Case 0
'nothing
Case 1
'1 argument
Case Else
'more arguments
End Select
End Sub

Hmm.... I'm afraid that won't work either, we are still looking for answers, but our anti-crack devices and such activated when i installed some new hardware that changed my internal info, so I corrupted the data. We have backups but we have to remake the forms.

DarkoLord

Well ALL three solutions work (if you know where to put them), so please be more specific...

From the source code displayed at this link:

Can you please inform me of where to put them, either by posting it here, or using:

To upload it.

Many thanks in advance.
