He'll need the MFC dlls plus any others that your program uses. There's a Visual Studio tool called 'depends.exe' which will tell you the Dlls that are loaded up automagically when the application starts (like msvcrt.dll for example) For any others you'll need to look for LoadLibrary calls in your code. Remember he'll already have most of those in your list as part of Windows so don't go overwriting vital items on his machine Big Grin | :-D

Because you're using code inside those DLLs by virtue of using an MFC database class. The code has to exist somewhere. By dynamically linking to MFC, the code is in the DLL which must be present on the executing machine. If you statically link, the code is pulled into your EXE and comes along for the ride when you move the executable to the executing machine.

http://www.codeproject.com/library/NeuralNetRecognition.asp
in vc++6 language.
I want to use this wonderful program as a dll or ocx in c#.
can anyone help me?
has anyone done this work before?
and can anyone give me this dll or ocx?
(i'm not familiar with nor understand difficult vc++6 programs)
very thanks in advance.

There are a number of steps I would recommend if you want what I think you want.

Use VC++ 2005 or 2008 to create a simple Dll project using the wizard. Play around with this and understand what it gives you and how to use that Dll from another project.

Take a class or module at a time from the article and add it into a copy of your Dll project. For each object create the necessary externally callable Dll interface or a COM based wrapper and test it.

You should end up with a Dll with all the functionality in it and accessible from outside.
Using this from C# either by use of PInvoke calls or COM interop is one for the C# guys on the C# forum, I've only done a very little COM interop which is great once it's working. Smile | :)

Send it a CB_RESETCONTENT message.

The same way you would send the CB_ADDSTRING message, unless MFC is hiding all of these details from you.

What's the problem? You previously stated that, "I used a GUID to represent a portion of a unique file name...", so did that work?

They hid it in the documentation. Those Bastards!
The secret lies in searching the MSDN for "GUID" and "creating".

But maybe what you want is just ::tmpfile() or ::tempnam() from stdio.h?

Let's think the unthinkable, let's do the undoable, let's prepare to grapple with the ineffable itself, and see if we may not eff it after all.

Hey! I did not ask!

Anyway, your code is missing the m_bufuid declaration.

Load AVI streams with MCIWnd.OpenInterface

Hi,

How can i load & play an AviStream using the OpenInterface macro ? My code compiles just fine but it does not show anything.

void CWrapperDlg::OnPlayAVI()
{
// Create the window like you would any Windows control.
m_mciWnd.Create(WS_CHILD | WS_VISIBLE | MCIWNDF_NOPLAYBAR | MCIWNDF_NOERRORDLG | MCIWNDF_NOTIFYERROR, CRect(0, 0, 300,300), this, 1234);

// Open the AVI file.

HRESULT hr;
PAVISTREAM pstream;

AVIFileInit();
hr = AVIStreamOpenFromFile(&pstream, "test.avi", streamtypeVIDEO, 0, OF_READ, NULL);
if (FAILED(hr))
AfxMessageBox("error");

m_mciWnd.OpenInterface((PAVISTREAM) &pstream);

//m_mciWnd.Open(strAVIPath);

// Play the opened AVI file.
m_mciWnd.Play();

// To keep the demo simple - can't play the AVI file more than one time.
((CButton *)GetDlgItem(IDB_PLAY))->EnableWindow(FALSE);
}

maximal number of dialogs

Hi everybody,

does it exist a maximal number of dialog ressources into a MFC Project.
My dialogs are under form of CFormView, but still now i have already over 25 dialogs

Does the project become buggy if a certain number of dialog ressouces is reached?

Big thanks for answers Smile | :)
