I know this sounds like a simple question, but let's not forget we're using MS technologies here....

If I declare a function in a header to be C-linkage, do I also need to declare its definition in the source file?

I've deleted your caveat, otherwise thanks for the answer.

I'm building a project, which is set to create a dll, and it's producing LNK2019 linking errors. ie it can't find dependencies. I thought that when you built a library you didn't need to provide it...

I expect there is a privilege that will enable it. Which one?

Hi folks,
I'm calling BlockInput in user32.dll, and it's failing with 5 Access Denied when UAC is on. How do I deal with this?

no, actually I think I need to look up boost BOOST_ALL_NO_LIB option.

I have cleverly discovered what "link library dependencies" is all about. I think it means "link against project dependencies". Are Microsoft good at misleading people?

hi folks,
I'm building an app and the error is

1>LINK : fatal error LNK1181: cannot open input file 'libboost_date_time-vc90-mt-sgd-1_42.lib'

and I haven't told it to link against this...

... you missed the bit that said

Further, no-one has commented yet on the purpose of the "link library dependencies" option.

you miss the point of my statement "if I build app P against A, it will only do so successfully if project A knows about B's library files." To make it clearer for you, perhaps I should state it...

b is what I'm aiming for. I seem to have achieved this, but I'd like confirmation that I'm doing it the right way: how do I build A.lib so as it copies everything it needs from B?

Further, will I...

indeed, Paul, but you're not answering my questions. (1) is not going to happen. (2) is not viable either.

i) if I tell project A where B's library files are, it produces an A.lib file which is bigger
ii) if I build app P against A, it will only do so successfully if project A knows about B's library...

Hi folks,
I'm building a library A which calls functions in library B. A depends on B.
I'm making an application P which calls functions in library A. That is, P depends on A. I want to arrange...

Hi folks,
how do you get windows to show you the security info of a process? If you right-click properties on a process in task manager it helpfully shows you the security details of the file, not...

Thanks for pointing this out. I am now getting the same error back from RegOpenKeyEx.

Hi folks,
Can someone tell me what I need to do to enumerate the subkeys of a registry key? Is there a special privilege for this which overrides the dacl or do I need to put an entry in the dacl...

well done prasad. You're right.

well I think I've outgrown codeguru. Maybe I should quit.

I'm not creating an array. I'm creating a pointer to a memory block.

I think I shall take my problem elsewhere.

engage your brain please.

I can set a pointer to NULL if I want to - I'm not accessing it yet.

I have explicitly supplied a second dimension :

double q[][8] = 0; /// not ok. THE 8 IS THE...

Trying to define a pointer to a 2d array which has a stride of 8.
If I know that my doubles are in a consecutive memory block at location p, and the stride is 8, then the notations

you are defining a pointer to an array of pointers.
From looking at the memory blocks in a debugger, it is clear that

double coslu1[8][8];

does not create an array of pointers.

hence

I'm not defining an array.
