I am writing a console program in VC++ 5.0 which uses MFC 4.21. My question is this: Can I, and how do I, use the Visual Studio string tables in my project? If this is possible then I am looking for a one-liner that shows how I access the strings in the table.

Thank you.

I assume you mean the string table resource type.  To use these, you need to put your strings in a resource file (*.RC).  The easiest way to do this is using the resource editor of Visual C++.  Each resource will be identified by a unique number, which is in turn is #defined using identifier (i.e. IDS_ERROR_STRING)

Strings from a resource string table are loaded with the Windows API function LoadString.  There is a LoadString member function in the CString class which initializes a CString with a resource string... however, it doesn't always work with console mode apps.

But of course, just because you are using MFC doesn't mean you can't call standard Win32 APIs.  Just prefix them with :: to clarify you want the standard API... both to the compiler, and to you.  The format is LoadString(HINSTANCE, UINT, LPTSTR, int) where the parameters are:

HINSTANCE - Represents the module (DLL/EXE where the string table is)
UINT - the ID of the string you want
LPTSTR - points to a buffer to receive a copy of the string
int - the size of the buffer in parameter 3

So, the call would be like this:

TCHAR errorString[80];
::LoadString(::GetModuleHandle(NULL), IDS_ERROR_STRING,
     {LPTSTR)errorString, 80);

GetModuleHandle(NULL) returns the handle of the current module containing the code calling LoadString.  So, this assumes that this calling code is from the same executable file that contains the string table.

The great thing about using string tables, of course, is that you can provide multiple versions of your string table in different languages, and the LoadString call will select the appropriate string for the language settings of the user's computer.
