I have an application that uses anonymous pipes to communicate with the child process which is altogether a separate application. I was using anonymous pipes in this context but the problem is with the blocking read which leads to the GUI hang. I want to use the same anonymous pipe with Non-blocking read. In unix i was able to do this with select system call but in windows this API seems to be socket specific. Please help.

Hi all.
Got a little Problem...
I have 4 Views (CFormView) with a TreeCtrl in it..
now i moved the tree into a Splitterwindow (created by CChildFrame).
Wehn User selects a DataView from the Menu I call OpenDocumentFile() whitch
call's afer ObCreateClient() where I switch between the View's...
Question :
How I get Access from CLeftView to the CChildFrame to change the View (wndSplitter->CreateView() or call funtions whitch Show Data within the CFormView ??
Thx. for Help !!!

Got it by myself after spending hours... 
Hier the code I used to get rid of it.... hope it helps someone...
BOOL CChildFrame::OnCreateClient(LPCREATESTRUCT /*lpcs*/, CCreateContext* pContext)
{
// Unterteiltes Fenster erstellen
if (!m_wndSplitter.CreateStatic(this, 1, 2))
return FALSE;
// create a new left pane !!
if (!m_wndSplitter.CreateView(0, 0, RUNTIME_CLASS(CLeftView), CSize(200, 200), pContext))
{
AfxMessageBox("Failed to create Client Frame Window!");
m_wndSplitter.DestroyWindow();
return FALSE;
}
CString m_Classname = pContext->m_pNewViewClass->m_lpszClassName;
// AfxMessageBox(m_Classname);
// selct the view
if (m_Classname == "CFrmAdressen")
{
// AfxMessageBox("Class ist CFrmAdressen");
if (!m_wndSplitter.CreateView(0, 1, RUNTIME_CLASS(CFrmAdressen), CSize(200, 200), pContext))
{
m_wndSplitter.DestroyWindow();
return FALSE;
}
return TRUE;
}
if (m_Classname == "CFrmArtikel")
{
if (!m_wndSplitter.CreateView(0, 1, RUNTIME_CLASS(CFrmArtikel), CSize(200, 200), pContext))
{
m_wndSplitter.DestroyWindow();
return FALSE;
}
return TRUE;
}
if (m_Classname == "CFrmAuftrag")
{
if (!m_wndSplitter.CreateView(0, 1, RUNTIME_CLASS(CFrmAuftrag), CSize(200, 200), pContext))
{
m_wndSplitter.DestroyWindow();
return FALSE;
}
return TRUE;
}
if (m_Classname == "CFrmInfoBox")
{
if (!m_wndSplitter.CreateView(0, 1, RUNTIME_CLASS(CFrmInfoBox), CSize(200, 200), pContext))
{
m_wndSplitter.DestroyWindow();
return FALSE;
}
return TRUE;
}
}
Leftview Treehandling :
void CLeftView::OnTvnSelchanged(NMHDR *pNMHDR, LRESULT *pResult)
{
LPNMTREEVIEW pNMTreeView = reinterpret_cast<lpnmtreeview>(pNMHDR);
CChildFrame *m_Child = ((CChildFrame*)GetParentFrame()->GetActiveFrame());
CWnd *p_Wnd = m_Child->m_wndSplitter.GetPane(0,1);
if (m_Child->GetRuntimeClass() == RUNTIME_CLASS(CFrmInfoBox))
{
CFrmInfoBox* m_Info = DYNAMIC_DOWNCAST(CFrmInfoBox, p_Wnd);
m_Info->OnTvnSelchangedTree1(pNMHDR, pResult);
}
}
*pResult = 0;
}
So I can Display and change view as before... but without using Tree in the FormView...
After I just a add a function to update the tree as I need...

Problem is that you have created DLL that Support MFC70.dll and Win98 support till MFC42.dll.
this only cauing teh Problem,only solution is to compile the library on 98 platefrom

Hi everyone
i'm working on a DLL with 2 Callback Functions but i really have no clue why it isn't working:
//MainClass.h (It's the DLL)
typedef void (__stdcall *LP_CREATEHANDLER_FUNC)(HANDLE, CString);
typedef void (__stdcall *LP_TERMINATEHANDLER_FUNC)(HANDLE);
class CMainClass
{
public:
__declspec(dllexport) void SetCreateHandler(LP_CREATEHANDLER_FUNC p_Handler);
__declspec(dllexport) void SetTerminateHandler(LP_TERMINATEHANDLER_FUNC p_Handler);
};
//ClientDlg.cpp TheMainApp
BOOL CClientDlg::OnInitDialog()
{
CDialog::OnInitDialog();
...
m_cls.SetCreateHandler(CreateHandler);
m_cls.SetTerminateHandler(TerminateHandler);
}
void __stdcall CClientDlg::CreateHandler(HANDLE hPID, CString strFilename)
{
}
void __stdcall CClientDlg::TerminateHandler(HANDLE hPID)
{
}
I get the following error:
error C2664: 'CMainClass::SetCreateHandler' : cannot convert parameter 1 from 'void (HANDLE,CString)' to 'LP_CREATEHANDLER_FUNC'
error C2664: 'CMainClass::SetTerminateHandler' : cannot convert parameter 1 from 'void (HANDLE)' to 'LP_TERMINATEHANDLER_FUNC'
what am i doing wrong ?

unless you use something like FastDelegate: http://www.codeproject.com/cpp/FastDelegate.asp[^] Boost also has libraries which can do this, but FastDelegate is simpler and works incredibly well.

HellO!!
I don't really know what happened or i might have edited accidentally the afxwin.h or another file. When I compile my Project even when I start a new MDI MFC skeleton application... i get this message:
c:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\atlmfc\include\afxwin.h(3970) : error C2501: 'CScrollView::CRectTracker' : missing storage-class or type specifiers
Is there anyway i can solve this before i can do reinstallation of VS .NET?

I'd like to have my tabbed dialog application using XP themes like "My Computer-> properties" in the win XP - the dialog inside the TAB control should use gradient background.
My problem is that static controls and check box buttons are not drawn properly -> background of the text is erased by default dialog background color (text background has OPAQUE mode). I've tried to handle the WM_CTLCOLOR message in the dialog, but this solved only the problem with text static controls, not with the group rectangle static box (it's text was drawn over the rectangle line when I've set text background mode to TRANSPARENT).
I hope there is some easier way than to code my own owner drawn controls, when windows GUI is using this.
Any suggestions ?
Thanks !

Looks strange because when an XP theme is active, all text labels are drawn transparently; in fact, no WM_CTLCOLOR handling is necessary. Does your app have a manifest resource in it that enables theming (the XP look) when a theme is active?
The gradient that you see in "My Computer-> properties" is NOT a feature of a themed Tab control, it's how the theme handles property sheets - it applies a gradient background to each of the dialog in the sheet. If you create your own tabbed dialog, you can do it by handling WM_ERASEBKGND in each of your dialogs.
Consider the following code excerpt; perhaps you will get some ideas on your group boxes (BTW, they belong to window class BUTTON, not STATIC):
BOOL myGroupBox::OnEraseBkgnd(CDC* pDC)
{
CRect rcCtrl;
GetClientRect(rcCtrl);
if (GetUXThemeState().IsThemeActive())
pDC->FillSolidRect(rcCtrl, ColorAdjustLuma(afxData.clrBtnFace, 750, TRUE));
else
pDC->FillSolidRect(rcCtrl, afxData.clrBtnFace);
PrintClient(pDC, PRF_CLIENT);
return 1;
}
void myGroupBox::OnPaint()
{
PAINTSTRUCT ps = {0};
::BeginPaint(m_hWnd, &ps);
::EndPaint(m_hWnd, &ps);
}

Thank you very much for your response. I'll try your code. I don't use property sheets besause of it's limitations. I have tab control which has child dialogs. I'm handling the child dialog's onEraseBackgroud where I do nothing, so oridinal tab control's background remains.
I have manifest file in my resources, so all buttons, group boxes, etc. looks like in Win XP theme.
So I don't know why my static controls are not drawn transparently by default 
I'm also calling InitCommonControls(); in the app's InitInstance() as recommended ...

Could you make a small screenshot of the text label portion of a group box and give a link? this can make the native Windows drawing procedure more clear.
Oh... I think all you have to do is give your group boxes sensible ID's (other than -1 /IDC_STATIC/), check them in the WM_CTLCOLOR handler, call pdc->SetBkColor() for these ID's and return a brush of a proper color. Do not set the background mode to TRANSPARENT.

Does anyone of you know how to develop a tool like tcpview(by sysinternals.com)? My requirement is to not just listing (as in TCPview) but to monitor and end a process before it actually starts. For example, i want to filter all applications passing through port 80 except Internet Explorer. so if some clicks any pdf file on Internet, he will not be allowed to do so? how do i proceed? i m really clueless and need some ideas.
Thanking u,

wParam
The low-order word contains the button's control identifier. (USE LOWORD macro here)
The high-order word specifies the notification message.
(USE HIWORD macro here)
lParam
Handle to the button
