CreateProcess problems in vb.NET (only experts need apply ;-)

[Paul Schenk]

Hi All :)

Would be grateful of advice please. I have code in VB6
working as follows:

lngReply = CreateProcess(s Null, txtStart, ByVal 0&,
ByVal 0&, 1&, _
NORMAL_PRIORITY _CLASS, ByVal 0&, sNull, sInfo,
pInfo)

but alas, the 'equivelant' vb.Net code translated as:
lngReply = CreateProcess(s Null, txtStart.Text, sa,
sa, 1, _
NORMAL_PRIORITY _CLASS, 0, sNull, sInfo, pInfo)
does not execute cleanly. That is, although the
CreateProcess returns 'successfully', and populates the
sInfo structure with valid data, the application (e.g.
c:\windows\note pad.exe) 'fails during initialisation' and
terminates.

The only 'meaningful' difference between the working vb6
and non-working vb.net code, is the substitution of
vb6's 'As Any' Win32API declaration parameterss with 'AS
Securities_Attr ibutes' structures, which I have defined
thus:

Structure SECURITY_ATTRIB UTES
Dim nLength As Integer
Dim lpSecurityDescr iptor As Integer
Dim bInheritHandle As Integer
End Structure

and are passed-in called 'sa', as noted above.

Please, can someone offer either a correction for my
error, or a good code example / reference for calling
CreateProcess from vb.net.

NB: I need to use CreateProcess rather than the Process
component that is available in the managed code, as I
need to set some 'lower level' start info parameters
(i.e. the lpDesktop setting), which I can only get at
using the API directly :(

Many Thanks in advance,
Paul.

That is the only answer the only "Expert" in this newsgroup can give.
