I use pipes with CreateProcess(), but my code works well on win98 and doesn't work on XP.
only special code for XP in my app looks like:
=========================
void*psd=0;
LPSECURITY_ATTRIBUTES psa=0;
DWORD bNT=(GetVersion()<0x80000000)?1 ;
if(bNT)
{
psd=::GlobalAlloc(GPTR,SECURITY_DESCRIPTOR_MIN_LENGTH);
::InitializeSecurityDescriptor(psd,SECURITY_DESCRIPTOR_REVISION);
::SetSecurityDescriptorDacl(psd,-1,0,0);
psa=(LPSECURITY_ATTRIBUTES)::GlobalAlloc(GPTR,sizeof(SECURITY_ATTRIBUTES));
psa->nLength=sizeof(SECURITY_ATTRIBUTES);
psa->lpSecurityDescriptor=psd;
psa->bInheritHandle=1;
}
const BOOL bOK=CreateProcess(0,pszCmdLine,psa,0,1,0,0,0,&si,&pi);
//======================================
do i need more special code for XP?
thx

Define "doesn't work." Are you getting a compiler/linker error, a runtime error, a fired assertion, or a thrown exception?

void*psd=0;
Shouldn't this be:
PSECURITY_DESCRIPTOR psd = 0; includeh10 wrote:
::SetSecurityDescriptorDacl(psd,-1,0,0);
I'm not sure of the behavior of this function when bDaclPresent is neither 0 nor 1.

What happens if you call this function with lpProcessAttributes set to NULL?

"doesn't work" means that messages do not exchange between pipes at all, the dos app respones for command in CreateProcess(), after that, communication stops.
i will test ur suggestion.

lpProcessAttributes!=0 is commented by docs, which say it is special for NT.
if lpProcessAttributes=NULL, it is the same (works on Win98 but not on XP).
I had many apps which use code above and work well on all platform - but they are Windows apps, not DOS one.
i can not find reason why the code has trouble on DOS app.
by the way, PSECURITY_DESCRIPTOR is just void*, some people define many sick definitions.
thx

I see it saying that the handle cannot be inherited and the process gets a default security descriptor. In any case, ...

Which should indicate to you that the following code has no bearing on the problem:
DWORD bNT=(GetVersion()<0x80000000)?1:0;
if(bNT)
{
psd=::GlobalAlloc(GPTR,SECURITY_DESCRIPTOR_MIN_LENGTH);
::InitializeSecurityDescriptor(psd,SECURITY_DESCRIPTOR_REVISION);
::SetSecurityDescriptorDacl(psd,-1,0,0);
psa=(LPSECURITY_ATTRIBUTES)::GlobalAlloc(GPTR,sizeof(SECURITY_ATTRIBUTES));
psa->nLength=sizeof(SECURITY_ATTRIBUTES);
psa->lpSecurityDescriptor=psd;
psa->bInheritHandle=1;
}Remove this and the problem becomes more refined. By removing unnecessary code, you'll eventually get down to just the few lines that are necessary to demonstrate the problem.

Fair enough, but it would make more sense to others if PSECURITY_DESCRIPTOR were used. There's also the (small) possibility that it may change from void* in the future.

Hello!
I need to interface my VC++ application with Outlook Express 6.0.
I'd need:
- access to email messages in Outlook folders,
- eventually, copy email messages in other files (with EML format and other
place);
- make email messages and send them with Outlook Express (Outbok).
I found a very useful sample on codeproject.com (made by Pablo Yabo), about using IStoreFolder and IStoreNamespace to manage Outlook Exp folders.
But ... what about outgoing emails? The sample can just make a "streamed" file, that's not sent by Outlook Express.
Do I need to use IMimeMessage interface?
Is there any sample that show the use of IMimeMessage interface?
Thank you in advance!
Chiara

I wan to make a simple calculator with 3 edit box 2 of them to insert the values and the other for the result. Mi problem is that when i insert the numbers and make the operation the storage the values and in the next operation i can't change it.This is what i wrote.Thanks for your help.
void CPractica6Dlg::OnMultiply()
{
UpdateData(TRUE);
m_result=m_numA*m_numB;
}
void CPractica6Dlg::OnCalculate()
{
UpdateData(FALSE);
}

My suggestion would be to nix the calls to UpdateData(). Then create three CEdit member variables, one for each edit control. Now in the OnMultiply() method:
void CPractica6Dlg::OnMultiply()
{
CString strA,
strB,
strC;
m_editA.GetWindowText(strA);
m_editB.GetWindowText(strB);
strC.Format("%d", atoi(strA) * atoi(strB));
m_editC.SetWindowText(strC);
}

Will it work?
void CPractica6Dlg::OnMultiply()
{
UpdateData(TRUE);
m_result=m_numA*m_numB;
UpdateData(FALSE);
}

I dont know what you mean?
Sorry i'm a little bit new with visual c++.
is this what are you talking about?
CDialog::DoDataExchange(pDX);
//{{AFX_DATA_MAP(CPractica6Dlg)
DDX_Text(pDX, IDC_NUMA, m_numA);
DDX_Text(pDX, IDC_NUMB, m_numB);
DDX_Text(pDX, IDC_RESUL, m_result);
//}}AFX_DATA_MAP

Situation out of control. Cease Fire!. But check the values of m_numA, m_numB & m_result by displaying in a message box jsut before the multiplication and just after the multiplication.

Values
m_a=1
m_b=2
pick radiobuton +
pick solution
m_result=3
then I change values
m_a=3
m_b=4
radiobuton + activated
pick solution
m_result=3 and m_a and m_b changed to
m_a=1
m_b=2
but if i do this it works
m_a=3
m_b=4
radiobuton + activated but i pick it another time
pick solution
m_result=7
