[RESOLVED] Trimming Nulls with SysReAllocString

[Bonnie West]

Hi! Can anybody please confirm that trimming null characters from a string using the function SysReAllocString is without any undesirable side-effect(s) such as memory leaks, etc.? MSDN has the following warning on the SysReAllocString function:

The address passed in psz cannot be part of the string passed in pbstr, or unexpected results may occur.

Here is a sample usage:

Private Declare Function SysReAllocString Lib "oleaut32.dll" (ByVal pBSTR As Long, Optional ByVal pszStrPtr As Long) As Long

Dim sTemp As String
sTemp = Space$(1048576)  '1 MB
Mid$(sTemp, 2&) = vbNullChar

'This function allocates a new string,
'copies the passed null-terminated string into it
'and then deallocates the old contents
Debug.Print CBool(SysReAllocString(VarPtr(sTemp), StrPtr(sTemp)))
Debug.Print Len(sTemp)    'prints 1

'This has the same effect as sTemp = vbNullString
SysReAllocString VarPtr(sTemp)
Debug.Print StrPtr(sTemp)    'prints 0

I hope somebody can shed light on this...
