When #include <dxatlpb.h> is removed, what compiler errors are generated?

Ok, so if you do not need it, why include it?

I would, but not having the DirectX SDK installed makes it somewhat difficult!

According to the KB (PSS ID Number: 243298):

CAUSE
The problem occurs because the function InlineIsEqualGUID() is defined both in the ATL header file, AtlBase.h, and the Platform SDK header file, Guiddef.h, in different name spaces. The include paths for the build point first to the Platform SDK include directory, and then to the ATL include directory. In the ATL header, InlineIsEqualGUID() is defined in a name space called "ATL", while in the Platform SDK header it is defined in the global name space. Because AtlBase.h includes the statement

using namespace ATL;

the compiler is unable to distinguish which definition to use.

RESOLUTION
To work around this problem, prefix the call to the InlineIsEqualGUID() function with ::ATL::. This explicitly qualifies the ATL namespace from where the implementation of InlineIsEqualGUID is pulled in. For example:

::ATL::InlineIsEqualGUID()

Playing avi video and reading video time

Hello

I have been doing a lot of reading lately on how to play a video from C++ using different methods such DX9 VRM and DirectShow.

I am trying to play a video and read the time from it. However I cannot see anyway in which I can do this. I was wandering if any of you coule maybe help. I cant find any samples or anything in MSDN for some that I would thought would maybe be straight forward.

At the current moment I am just using shell extensions to load the video from C++ but this doesnt allow the time to be read.

Thankyou kindly for any help

Unable to capture ENTER key on a CEdit Control

I'm trying to capture the ENTER key on a CEdit Control with the OnKeyDown() function, but it seems that it is not capturing the ENTER key. All the other keys are being captured as it should. i'm using my own edit control, derived from CEdit class.

Any tip ?

Thanks.

You can catch the ENTER key in your own edit control class in PreTranslateMessage:

BOOL MyClass::PreTranslateMessage(MSG* pMsg)
{
if(pMsg->message == WM_KEYDOWN && pMsg->wParam == VK_RETURN)
{
DoAnything();

or

// pMsg->wParam=0;
}

return CDialog::PreTranslateMessage(pMsg);
}

CArchive - Reading strings

Anonymous9-Feb-04 4:25

Hello!

I have written an object to CArchive. My object consists of a CString and an integer. I gave up using the CArchive::WriteString() and CArchive::ReadString() functions as it seems CArchive can only handle simple types. So I write my object like this:

nLength = myStr.GetLength();
(*pArchive) << nLength;
pArchive->Write(myStr.GetBuffer(nLength), nLength);

To read back my object is not as easy as I think it should be:

CString tmpStr, myStr;
(*pArchive) >> nLength;
tmpStr.Empty();
pArchive->Read(tmpStr.GetBuffer(nLength), nLength);
myStr.Format("%s", tmpStr);
tmpStr.ReleaseBuffer();

Can anyone suggest an easier way? Thank you Smile | :)

Because CArchive knows how to stream to/from a CString, you can just use the >> and << operators.

Thank you Ravi.

I thought this was how CArchive would work at first too but I had problems and I now think my code was wrong elsewhere because now I fixed other problems as well and I tried what you suggested again and it works OK now.

I also had tried the WriteString() and ReadString() functions but I had problems with them also.

Memory Leak Finder

I am looking for a tool to aid our development and QA team find memory leaks. Right now we use Perfmon to monitor Private Bytes of application but we are ready to invest in a more advanced tool. Can anyone suggest some tools for me to research?

Environment is VC6 on W2k and higher. Applications range from services to GUI apps. We use STL, MFC and other 3rd Party libraries.

Thanks!

to find memory leaks is the easiest possible thing.
just create own new/delete, malloc/free, ... functions and add an item to a list when something is allocated and delete the item when there is a free call. so when the app will be closed, you can dump all the remaining items(leaks).

Data from one dlg to another

Hi,
I need help again Smile | :)

I have one dialog which I will call InvoiceDlg. On this dialog I have some controls. Lets say I have a static control called IDC_INVOICENUMBER. I have a button, IDC_TENDER, and when this button is pressed it will open another dlg called TenderDlg. I want to be able to get the data from InvoiceDlg into TenderDlg. I've tried alot of things such as:

void CInvoice::OnTender() <br />
{<br />
<br />
CString invoicenumber;<br />
	GetDlgItemText(IDC_INVOICENUMBER,invoicenumber);<br />
	CTender dlg;<br />
	dlg.DoModal();<br />
	dlg.m_invoiceme.SetWindowText(invoicenumber);<br />
}

and;

void CInvoice::OnTender() <br />
{<br />
	// TODO: Add your control notification handler code here<br />
	CString invoicenumber;<br />
	GetDlgItemText(IDC_INVOICENO,invoicenumber);<br />
	CTender dlg;<br />
	<br />
	dlg.DoModal();<br />
	dlg.SetDlgItemText(IDC_INVOICE,  _T(invoicenumber));<br />
	<br />
	<br />
}

Both these compile with no dramas, however when I try them in the app; they dont do anything, its like they aren't even passing on the data through CTender dlg;

Can someone please help me?! Im tired, I want to goto bed Cry | :((

lol
Thanks

The call to dlg.DoModal will show the dialog and therefore any further code in your function won't be executed until the dialog is closed.

You'll need to pass the CString into your class before DoModal and then inside the WM_INITDIALOG handler, set the window text of the control.

e.g

<br />
void CInvoice::OnTender() <br />
{<br />
// TODO: Add your control notification handler code here<br />
CString invoicenumber;<br />
GetDlgItemText(IDC_INVOICENO,invoicenumber);<br />
CTender dlg;<br />
<br />
dlg.m_strInvoiceNo = invoiceNumber;<br />
<br />
dlg.DoModal();<br />
<br />
<br />
}<br />
<br />
BOOL CTender::OnInitDialog()<br />
{<br />
   CDialog::OnInitDialog();<br />
<br />
   m_invoiceme.SetWindowText(m_strInvoiceNo);<br />
<br />
}<br />
<br />
<br />
<br />

Problems by getting current sel Item - Outlook

Hi,
I´m having problems by getting the current selected (current deleted) Item in Outlook.
For example:
When I am deleting an Contact in Outlook my programm catch this event and should get the current selected item but instead
of giving me the index 6 (for exampl.) it gives me the index 5 because outlook sets the selection to highest index shortly after someone is deleting ...

Whats wrong ?

I need badly help, cause I´m working in time-critical project ...

Thanks a lot, JohnX

The Problem is, that I am building a dynamicly EventHandler who gives me the events from user defined Folders.
(for example a Subfolder under Contacts)
As long as I only programm Events to the TopLevelFolder - everything works;
but when I programm Events to an user defiend folder the GetSelection() returns not what I really have selected.

Can someone help me ?
