If your VB code works ok, but your C code doesn't work (although no compiling errors), why don't you try to execute both codes debugging step by step and compare intern variables, returns and so on. That way you should be able to isolate where the problem exactly is, and with this section, then come back to forum. Im sure that you will have a perfect answer to help you from anyone of the good programmers that are here.

If something has a solution... Why do we have to worry about?. If it has no solution... For what reason do we have to worry about?

What exactly is _return being used for?

I SOLVED THE PROBLEM!
MSDN says EmptyClipboard() call provides the Win Clipboard
being released from avery thread previously attached to
it. Therefore, the OpenClipboard(NULL) call I perform
is vanified by subsequent EmptyClipboard(), and
I need one more OpenClipboard call.
THE STRANGE THING IS THAT THIS IS PERFECTLY TRUE IN C++,
BUT NOT IN VB6, FROM WHICH I WAS MIGRATING THE CODE!!!
mAH?

hello!
I`m not a choleric person, but this time i`m 2 steps away from madness!
I need to copy a file from one folder to another, so I`ve learned that i have to use
File.Copy, which is found in mscorlib.dll
I cannot find mscorlib.dll. Moreover, I don`t know how to link a lib to my project, so I usually simply "add existing item..." to my solution, and things just work. Only that this time it seems I can`t find the right mscorlib.dll
I have installed Visual Studio 2005, SP1, SDK for SmartDevices (WIN CE 5.0 and 6.0) - needed for some applications.
Visual Studio is installed in D:\Program Files\
I`ve seen that I have to download .NET Framework 2.0 (or 3.0), and I have downloaded them both from microsoft`s site.
Now, by searching my computer, i find 3 results of mscorlib.dll, in:
D:\Program Files\Microsoft Visual Studio 8\SmartDevices\SDK\CompactFramework\2.0\v1.0\WindowsCE
C:\Program Files\Microsoft.NET\SDK\CompactFramework\v2.0\WindowsCE
C:\Program Files\Microsoft.NET\SDK\CompactFramework\v2.0\Debugger\BCL
(.Net installs itself without configuring the path)
(Where the hell is v3.0 ?!)
Long story short, how can I get to use File.Copy ?
I have seen that I must write:
<br />
#using <mscorlib.dll><br />
using namespace System;<br />
using namespace System::IO;<br />
By simply writing those lines, without any adding of that lib to my project (or adding any of those 3) I get errors on "identifiers not found".
I `ve seen that mscorlib.dll appears in many System related functions, so I hope someone will know how to make it work...
While waiting for this answer, I`m using fopen to continue working with the data, but I can`t finish my application without create folder and file.copy.
Many thanks for any suggestion!

You shouldn't need to pull in mscorlib.dll - it's done automatically.
It looks to me like you're trying to use .NET classes in a native application.
Please post EXACT error messages so we don't have to guess 
Also, if you're really writing managed code, please post your questions here:

Right... It does seem like i`m trying to use native/managed code. But that is not true. This time, it`s a win32 application, not intended for a smart device. Those WinCE findings are simply because I have installed the SDK for native coding.
Anyway, i`m adding my code and my errors:
Code:
<br />
#using < mscorlib.dll ><br />
using namespace System;<br />
using namespace System::IO;<br />
[...].br />
<br />
FileStream^ xmlRegister = File::OpenRead("Settings.ini");<br />
Errors:
<br />
.\ADN FixDlg.cpp(99) : error C2065: 'FileStream' : undeclared identifier<br />
.\ADN FixDlg.cpp(99) : error C2065: 'xmlRegister' : undeclared identifier<br />
.\ADN FixDlg.cpp(99) : error C2653: 'File' : is not a class or namespace name<br />

 Huh?

To me, a Win32 application is native code. In that case you can't use .NET classes.
Everything you're showing is managed/.NET-related.

Then let me explain how I am creating the project:
First of all, i select visual c++
From there, i select MFC ( if I had chosen Smart Devices, it would have been managed )
Then, MFC Application
After that, I start configuring my application - dialog based, winsockets etc
I am afraid I don`t understand what you mean by .NET classes ... I have seen that mscorlib.dll functions are descriped on a page with a note that the info applies to .NET Framework 3.0 and which provides links to .NET Framework 2.0 and 1.1 for the same information (please see the first link in my initial question)

mscorlib is part of the .NET framework.
The System.IO.FileStream class is also in the .NET framework.
The only way you can use classes in the .NET framework from C++ is
using managed code - code compiled to CLR.
An MFC application, by default, is a native application - not compiled to CLR.
There's plenty of ways to access files without using the .NET framework, but
if you want to use .NET, you have to compile the code which uses it to CLR.

Well then, that`s an A answer...
This being told... how can I copy a file without using .net framework ? i don`t 'want' to use .net... I simply thought I had to...

A variety of ways...
If you're not concerned with ANSI C++ portablility and you're targeting Windows
You could use CopyFile()[^], CopyFileEx()[^], SHFileOperation()[^]
There's also numerous ways to open, read, write, close files if you want to do the work yourself.

What version of visual studio are you using ? one of the "express" versions ? If that's one of those, then you cannot do MFC.

Hi
Is there class or function set for working with INI sections not in file, but in set of strings?
I have some database with one text field which contains content of INI file. But I haven't possibility to write this to file on disk and read it after that.
Rgds,
Ernst

have you searched the web before asking ?
is CIni[^] of any help ?

Doesn't this class require a file to operate on?

Can I set an application to run each time with a certain priority without chainging from Windows task manager?

Any reason you can't just call
<br />
BOOL WINAPI SetThreadPriority(<br />
HANDLE hThread,<br />
int nPriority<br />
);
on your main thread on startup?
Nothing is exactly what it seems but everything with seems can be unpicked.

#define HIGH_PRIORITY_CLASS 0x00000080<br />
#define REALTIME_PRIORITY_CLASS 0x00000100<br />
<br />
SetPriorityClass(GetCurrentProcess(),HIGH_PRIORITY_CLASS);<br />
Note that setting the priority too hugh can cause other processes/threads of lower priority to become starved.
