You may rebuild all again, and copy the content in the Build tab of the Output window.
Or you may copy what in the .plg file....

when i define it that way Visual C++ compiler says: "error C2011: '_ID3Info' : 'struct' type redefinition"
From the looks of it, it seems that _ID3Info is somehow aready defined. It could be that:
1. You have a struct of that name defined somewhere else
2. Perhaps you don't have "include guards" in the header file that defines the struct, and it is getting pulled in twice. I always do something like this to ensure that #2 does not happen:
#ifndef _whatever_your_h_file_name_happens_to_be_
#define _whatever_your_h_file_name_happens_to_be_
(code of the include file goes here)
#endif
No generalization is 100% true.
Not even this one.

Like Navin, your struct compiles fine in my code. I think if you follow his advice you'll find the source of your problem.

Again some newbie-problems 
I want to use the AVIFile API in my c++ project. Including the "Vfw.h" header file is not a problem, the various datatypes such as PAVIFILE can be used.
But when the project tries to link to the windows dll (mswfv32.dll), the linker says:
Linking...
AviKaka.obj : error LNK2001: unresolved external symbol _AVIFileInit@0
AviKaka.obj : error LNK2001: unresolved external symbol _AVIFileExit@0
Debug/MultiKaka.exe : fatal error LNK1120: 2 unresolved externals
I've already tried to add the dll manualy in project->settings->debug->additional_dlls
So, I guess this is probably a how-to-call-a-dll-topic 
Inluding the headerfile is not enough

Are you sure that the definition and prototype of _AVIFileInit is the same?

Yep, source found on msdn library.

There are two ways to use a DLL:
1) static use
You need a header-file and a lib-file added to your project. Than you can directly call the functions declared in the header file.
(Due to the linker errors it seems the lib-file is missing in your project, adding only the dll won`t work)
2) dynamic use
You only need the dll-file. From your source you load the dll by calling LoadLibrary() and get the function pointers by calling GetProcAdress().

the lib-file is not missing. checked it.
Is there a way to view the dll member functions, (not the headerfile)? maybe they've changed.
If I use it dynamicaly, can I use the dll-functions more or less in the same manner?

Use the depends.exe tool comes with your VC++.

Within Visual Studio 6.0 there is a tool called "DUMPBIN".
Copy this to your DLL Path and type the following line from a console:
dumpbin /exports yours.dll
A list of the exported functions should be shown.

Add vfw32.lib in Project|Settings|Link, Object/Library modules. It's not a static lib but an import lib (you can tell because it contains only names). Your exe will link at runtime to the right dll and more importantly will compile ok too. tried just now with this fantastic test program:
#include <windows.h>
#include <vfw.h>
int WINAPI WinMain(HINSTANCE,HINSTANCE,LPSTR,int) {
AVIFileInit();
AVIFileExit();
return 0;
}
(I think you can only do the thing with putting libs into your project with static libraries, which contain code as well as import names, but I'm not sure.)

I've included the Vfw.h header file, but the lib-file is called vfw32.lib and its in Microsoft Visual Studio\VC98\LIB
Does the added 32 cause any harm here?
The lib dir is good?

And I've checked the lib for _AVIFileInit@0 and it's in it, allright.
I'm missing something here.

You need to make sure the Vfw32.lib is included in the ProjectSettings->Link->Input->Object/library modules properties.

That's it, allright! 
I thought that the linker uses the standard libraries in vc98\lib directory by default. But you have to include them on the link-tab. I did that only for the debug-tab.

Why handler WM_NCLBUTTONDOWN inside CEdit does not receive the notify at click of the mouse outside it?
Best regards,
Eugene Pustovoyt

From MSDN
WM_NCLBUTTONDOWN
The WM_NCLBUTTONDOWN message is posted when the user presses the left mouse button while the cursor is within the nonclient area of a window. This message is posted to the window that contains the cursor. If a window has captured the mouse, this message is not posted.

I'm not capture the mouse!!!

Hi Eugene,
The WM_NCLBUTTONDOWN message is only generated when a mouse is clicked on the nonclient area of the edit control (ie. the border, the one or two pixel wide area around the client area), it is not generated when the mouse is clicked outside the control.
What Michael was refering to is that once the mouse has been captured (via SetCapture()), all mouse messages are treated as client area mouse messages for the window that has captured the mouse.

Thank you PJ!!!
That is I do not have other exit to determine, what click outside the control except for as through capture of the mouse has been made?
If yes, where it is better to me to grasp the mouse if it is necessary for me, that it has been captura after his creations?
P.S. Thank you for your CFileEditCtrl & CPJAImage
Best regards,

If you want to know if the mouse is clicked outside the edit control, capture it with SetCapture(), then handle WM_LBUTTONDOWN and check the point is in the rectangle returned by GetWindowRect() using PtInRect(). Just remember that GetWindowRect() is in screen coords and WM_LBUTTONDOWN is in client coords.
