Run a VBScript file To run a VBScript from within another VBScript:

Dim objShell Set objShell = WScript.CreateObject("WScript.Shell") objShell.Run "cscript c:\batch\demo.vbs" Run a CMD batch file To run a CMD batch file from VBScript:

Dim objShell Set objShell = WScript.CreateObject("WScript.Shell") objShell.Run "c:\batch\test.cmd" Run a PowerShell script

To run a PowerShell script from VBScript: Dim objShell Set objShell = WScript.CreateObject("WScript.Shell") objShell.Run "powershell -file ""c:\batch\demo.ps1""" -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------Find and replace a text string in a file.

IsBlank function

The IsBlank function below will return True if the variable or value passed to it is Empty or NULL or Zero. It will return False if the variable contains any string or a value other than '0'. Function IsBlank(Value) 'returns True if Empty or NULL or Zero If IsEmpty(Value) or IsNull(Value) Then IsBlank = True Exit Function ElseIf VarType(Value) = vbString Then If Value = "" Then IsBlank = True Exit Function End If  ElseIf IsObject(Value) Then If Value Is Nothing Then IsBlank = True Exit Function End If  ElseIf IsNumeric(Value) Then If Value = 0 Then wscript.echo " Zero value found" IsBlank = True Exit Function End If  Else IsBlank = False End If  End Function Arguably the numeric value '0' is as valid a v alue as any other number. The logic behind flagging this as blank is that you may have data like a Price or a Surname = 0 which most likely should be treated as being blank. All vbscript variables are variants. A Variant is a special kind of data type that can contain different kinds of information, depending on how it is used. Examples using the function above Wscript.echo "testing 0..." boolReturn = IsBlank(0) if boolReturn = true then wscript.echo "It's B lank" else wscript.echo "not blank"

Wscript.echo "testing 123..." boolReturn = IsBlank(123) if boolReturn = true then wscript.echo "It 's Blank" else wscript.echo "not blank" Wscript.echo "testing 100-100..." boolReturn = IsBlank(100-100) if boolReturn = true then wscript.echo "It's B lank" else wscript.echo "not blank" Wscript.echo "testing null..." boolReturn = IsBlank(null) if boolReturn = true then wscript.echo "It's B lank" else wscript.echo "not blank" Wscript.echo "testing empty string..." boolReturn = IsBlank("") if boolReturn = true then wscript.echo "It's B lank" else wscript.echo "not blank" Wscript.echo "testing string..." boolReturn = IsBlank("The quick brown fox") if boolReturn = true then wscript.echo "It's B lank" else wscript.echo "not blank" --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------CSCRIPT datetime.vbs 'Returns Year,Month,Day,Hour,Minute,Seconds,Offset from GMT, Daylight Savings=True/False strComputer = "."
