I think we need some more details. Can you access the folder to get a directory listing? Is this a local or remote folder? Do you have administrator access to the folder/file? Is this at a command prompts or in some application?

This may be a simple matter of Windows not trusting the source of the file. I know that sometimes when downloading files Windows will semi-quarantine them and you need to enable access manually. Take a look at the file itself and check the properties.

Hello together, 

I´m try to get a communication between a process written in c++ and a process written in c#.
Each Processes have a RPC Server ans a RPC Client.

The following situation exists:
It´s possibel to start a correct RPC communication between 2 processen written in C++.
And it´s also possible to start a correctly RPC communication between 2 processes written in C#.

It´s not possible to start a correctly RPC communication between a process written in c++ and a process written in c#.

The interface is initialized with the "ncacn_ip_tcp" protocol.

The error accours in the function "NdrGetBuffer(,,)". This function is declared in "rpcndr.h".
The client use this function for getting a pointer from the RPC server to send the requiered datas. 

I don´t no how shall I do now.
Is there anyting to setup in user settings?

Can someone help me?
Have someone also problems with RPC Server / Clients


Thank You very much.

So the Troubleshoot Remote Procedure Call (RPC) errors - Windows Client Management | Microsoft Docs could be a good start.

Hello,

thanks for the hint.
I´ve already scoured this page.
In my application the server and client works with "endpoint" definition
not with ports.
As I said.
Processes that are written in C ++ communicate with one another, as do the processes that are written in C #. This is not a problem.
No communication between processes written in C ++ and processes written in C #.

If someone has these problems in the same way, I would be happy to hear from you.

Thanks a lot

std::cout inside of object

I have a simple console app. I instantiate a CTest class. How can I output a console inside of class ?

C++

int main()
{
    CTest test;
    test.ListItems();
}

C++

CTest::ListItems()
{
    CString s(_T("abc"));
    std::out << s;
}

and the output console show:

01378168

. I have tried several things, but something I am missing.
Of course, the app recognize CString.

How about

CString s(_T("abc"));
std::out << (LPCTSTR)s;

Is it Unicode? If so, you may have to use wcout instead.

You need to use one of the methods of CString or CSimpleString that returns a pointer to the characters. The cout function does not understand an MFC object reference.

Hi,

The CStringA class has an operator LPCTSTR which means you should be able to use it with cout. There is also a CString::GetBuffer().

Yep,

I always disliked the TCHAR hacks. Although I do still find myself using the L and _T macros for string literals. Smile | :)

Ok, it would have been at the Submixer[^] which is at the commons area. I went out of my way to make it there in the evenings just to see some of the people from the online forums.

Actually now that I think about it, it was probably Marius Bancila. In my mind I've always had both you guys organized as the "Codeguru mvps".

Insert or embed File Dialog in a CPropertyPage

I'm trying to see if I can embed a CFileDialog to a CPropertyPage.

I stumbled on this question with a minimalist answer (I've asked there also) : Re: CFileDialog in CPropertySheet - C / C++ / MFC Discussion Boards

The id IDD_FILEOPEN_EX does not exists, can I replace it with AFX_IDD_FILEOPEN ? (there's not seems to be a IDD_FILEOPEN id ).

also,

If I need to include dlgs.h to have access to the id stc32, do I need to include an additional RC file somewhere.

Or, is there a more modern way of doing this ?

Thanks.

I'd rather be phishing!

The AFX_IDD_FILEOPEN is defined in afxres.h that is by default #incuded in your resource.h file.
