I am just calling the command provided by the Autodesk Inventor and I can't got the state infomation of the device context.
In addition. I can get the relative objects through API if the paste succeeds, but I got nothing, indicating that the paste failed
Thank you very much!!!

More detail would help, but if I had to guess:
It works with the AfxMessageBox call but not with the Sleep call. This suggests the operation needs a message pump running.

yes, it is quite ture that It works with the AfxMessageBox call but not with the Sleep call.
what detail do I need to provide?
Thank you very much!!!

I need more details on the implementation of the methods you're calling.
Steve

these methods are all provided by the API and no implementation is availalbe.
I just know that a message box has to be inserted.
Thank you very much!!!

Is there any documentation for these methods that describe the environment needed by them?

Try code like this (instead of the AfxMessageBox call - since a message pump seems to be required):
UINT TimerId = SetTimer(NULL, 0, 5000, NULL);
MSG m;
BOOL bOk;
while ( (bOk=GetMessage(&m, NULL, 0, 0)) && bOk!=-1 )
{
DispatchMessage(&m);
if ( m.message==WM_TIMER && m.wParam==TimerId )
{
break;
}
}
KillTimer(NULL, TimerId);
Caveat:
I don't really know what's going on or what you’re trying to do or the over all structure of your program so this is just a guess. I have hard coded a 5 second delay. You will be able to use the UI of the app during this time - You may want to simulate modality by putting a call to disable the main app window before and another to re-enable it after. 9 times out of 10, when you put a hard coded delay in a program your doing the wrong thing: How long do you wait? Will this be long enough on a slower machine? If you wait long enough for a slow machine are you "cheating" users with fast machines?

these codes are to be put into a function in a class which is derived from a MFC class CDialog.
so when I copy the codes you provided, following errors occur:
error C2660: 'SetTimer' : function does not take 4 parameters<br />
error C2660: 'KillTimer' : function does not take 2 parameters
and I don't know how to call the two functions SetTimer and KillTimer of API version while there exists CWnd::SetTimer and CWnd::KillTimer
I don't much about these functions, so could you please tell me how do it?
Thank you very much!!!

Put a "::" (two colons) in front of the effected functions. This will tell the compiler to use the global versions and not the member functions of the same name.
ie.
::SetTimer and ::KillTimer

thank you, Stephen Hewitt, I appreciate your help so much.
it works finally with your help!
in fact, it dosen't matter how long the time delay is set to be. I set it one milisecond, it works too
thanks a lot to all the other guys.

In that case you could try code like the following:
MSG m;
while ( PeekMessage(&m, NULL, 0, 0, PM_REMOVE) )
{
DispatchMessage(&m);
}
This is simpler. It dispatches all the messages in the message que then continues on - And no time delay.

For some reason, I cant get any simple program, using
the new visual studio 2005, to compile if it has a CString
as a variable or if I use #include <fstream>.
I am extremely perplexed. I know that CString is equivalent
to const char * and I guess I could use that, but I really
liked being able to use CString and am hoping I still can
somehow. Also, if I want to open an ascii file and close
it, I use the #include <fstream> header, but I keep getting
an error with that line.
Any ideas?? Please, any response any one can give me will
be greatly appreciated.

Why? What errors are you receiving?

Here is a common error I get using CString:
error C2664: 'strcpy' : cannot convert parameter 2 from
'CString' to 'const char *'
I use to pass a CString, but it doesnt recognize CString
anymore. If I pass const char *, it works?
If I type #include <fstream.h>, I get:
fatal error C1083: Cannot open include file: 'fstream.h': No such file or directory
If I type #include <fstream>, I get more errors.
So Im stumped. Its a very simple program that compiles in
Visual C++ 6.0, but using Visual Studio 2005, I get errors that
I cant seem to get past.
Please, any response any one can give me will be greatly
appreciated.

Does the file exist on your machine? Are your paths (environment variables and IDE) set up correctly? One way to check is to right-click on the #include statement and select the "Open Document..." option.

What does the statement look like?

Shockingly, when I right-click on the include statement, it doesnt
seem to exist. Do I have to copy and paste that file in? It doesnt
make sense. Under the older compiler, it just existed. I didnt
have to add that class to the project.
Please, any response you can give me will be greatly appreciated.

Here are 2-snippets of code that generate errors with CString:
if(strlen(ps->Text)==0)
return 2 * ps->PointSize;
Here I get:
'strlen' : cannot convert parameter 2 from 'CString' to 'const char *'
It doesnt recognize the CString.
And here:
LPCSTR CPage::SetFont(LPCSTR FontName)
{
static char buff[40];
strcpy(buff,m_PrtDesc.FontName);
if(FontName != NULL)
m_PrtDesc.FontName=FontName;
return buff;
}
I get:
'strcpy' : cannot convert parameter 2 from 'CString' to 'const char *'

Why are you not using CString::GetLength() here?
In any case, if you must use strcpy() and strlen(), you'll need to use the Unicode version, or the macros defined in tchar.h:
_tcscpy()<br />
_tcslen()
