Yes: I see two colons in the latter statement, missing in the former one.

It's called the scope resolution operator.

It's usually useless. But you do need it when there happens to be another FreeLibrary function visible in the current scope that hides the ::FreeLibary API. This actually happens with CWindow API wrappers, which are named after the APIs being wrapped.

Ummm, I guess the command line option '-B' is not supported... 
More seriously, what does your complete command line look like?

The above doesn't provide me with any information that can be used to help you.
The fact that you have not changed any settings is irrelevant.
I specifically asked for a piece of information that might be relevant, but you failed to provide it.
This means that at least I cannot help you until you answer my question.

I recall there's different versions of the IDL compiler out there.
I think there's a newer one in the windows SDK version 6.
Maybe you need that?

Good afternoon!
I'm trying to create a Dll file and i have a lot of .h and .c files to insert on it. I already saw MSDN article "how to create a dll file" but the sample presented is simple and only includes one source code file. How to create my Dll file? Anybody knows documentation about this subject with good samples?
Best Regards.

Are you using Visual Studio and its project/solution system or
building from the command line?

Walkthrough: Creating and Using a Dynamic Link Library[^]
The section "To add a class to the dynamic link library" explains adding a new source/header
file combination to the project. To add existing files to the project, choose "Add Existing Item…"
instead of "Add New Item…".

How about starting in the DLL section of CodeProject[^]?
At least so you can better explain what you want to do and more specifically what your problem is.

Essentialy, my problem is how to insert my .h and .c files in a project to build a .dll one.

In that aspect there's no difference between a DLL project and an ordinary project.
You add the files in the solution/project explorer.
One difference you will eventually come across is that a DLL exposes some kind of interface, a number of functions you can call from the client that loads the DLL.
Try to keep things as simple as possible and gather all the functions in the exposed DLL interface in one single source (.c / .cpp) file.
Since a DLL serves to perform operations that are logically connected in way or the other, it makes sense have the interface implemented in one single file. At least in the beginning.
Mark has provided you with another good starting point.

I used Visual C++ 2005 to generate an MFC doc-view sample application. I got an strange error message when I try to open an previously save file in MFC in a static library. I have traced the problem and it was the codes in MFC provided docmgr.cpp below which caused the problem:
BOOL CDocManager::DoPromptFileName(CString& fileName, UINT nIDSTitle, DWORD lFlags, BOOL bOpenFileDialog, CDocTemplate* pTemplate)
{
CFileDialog dlgFile(bOpenFileDialog, NULL, NULL, OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT, NULL, NULL, 0);
CString title;
VERIFY(title.LoadString(nIDSTitle));
dlgFile.m_ofn.Flags |= lFlags;
...
}
The VERIFY(title.LoadString(nIDSTitle)) statement gives VERIFY's error.
However, if I compiled the application in "Use MFC in a shared DLL".
Then compile and build it, it can work without any problem!
Anyone know what the problem is?

looks like the string id isnt representing a string in your resource. Make a "Rebuild all" and look whether the id is a valid string.

I have tried rebuild all and did not work...

Have you set a breakpoint on that statement to see what the value of nIDSTitle is, or how about stepping into the LoadString() method to see what it is returning?

Tried step into debug, nIDSTitle seems to be the standard AFX_IDS_OPENFILE (61440).
It seems the standard AFX_IDA_... are defined in afxres.rc, how how comes this file is not included in the project. Therefore it seems to be related to project setting to solve it. Just dunno.
Any idea?

MFC wants that you assign a string to AFX_IDS_OPENFILE

Does anyone know whether it is possible to install a Caption Bar , Like the one created in VS2008 thru the wizzard, for an old VS6.0 program? I want to refresh the look and feel of the VS6.0 program without having to rewrite it in a new VS2008 program. Is this possible? Please identify how with some code snippets please.
