Forcing a Compile-Time Link to a DLL

How can I instruct Visual Studio 2005 to include a certain DLL as a compile-time dependency of the EXE even though my code never calls any functions in the DLL?

It's a resource-only DLL, but I want Windows to load it into the process when the process launches without me having to call LoadLibrary.

I figure since no functions are ever called, the linker would ignore it by default.

If it is a resource dll you need the HANDLE to set it to "Current Resource Handle".

If you only need the resources, you can also change the resource code of your exe module.

Maybe export one function - the function could just return the HMODULE for the DLL, which you'll
need anyway. Create an import library in the DLL project and link to that library in your app
project.

SetSystemTime - GMT and BST

my app allows the user to change the current time on the pc and it also displays the current time at the bottom of the apps window (its a full screen app so the user can't see the windows time).
I've noticed that when I change the time in my app it changes correctly however the windows timer gets an extra hour added, I'm assuming this is due to BST, what is the preferred method for changing the time correctly so I don't get this extra hour?

TIA,
Andy

Hi all,

I would like to know which function I can use to count the number of threads associated with a specific thread. i.e. How many threads does a specific process have?

Thanks in advance

Error when Building the code

Hello.
I'm new in Socket Programming and I found that the sample program in this page is easy to understand.
Attached sample project is working fine in Microsoft Visual C++ Express Edition.

But I had a problem when trying to make an exact copy of the program,
by creating new empty project and add the sources ( attached "sock.h", "sock.cpp", and "main.cpp" ) to the project.
When I trying to build the project, there's some errors as below.

I suppose that the errors came from different "Project Properties".
Anybody could help me?

You need to link to the winsock library: go into the project properties -> 'Linker' -> 'Input' and in 'Additional dependencies' you need to add 'ws2_32.lib'.

Your guess it is right.
You have to add Ws2_32.lib to the LINKER library list.
On my system (VS 2003) this can be done by selecting 'Project->Properties" menu and then (on the newly shown window), after selecting the 'Linker->Command Line', add Ws2_32.lib to the 'Additional Options' TextBox.

It Works!!
Thank you very much( for both Cedric Moonen and Pallini ).
You just made my day.

I also added "odbc32.lib", "odbccp32.lib", "wsock32.lib" to Additional Dependencies,
and it works. But it was derived from yours, so thanks.

There were no error anymore when building,
but when I debug it, there was a dialog bog:

I chose OK and there were no problem ( and the server worked fine ).
Just curious. Any suggestions?

You started to debug your program (you pressed F5 probably) but your program was build in release mode probably. That means that it doesn't contain any debugging information and you won't be able to use the debugger.
