I have a library in a file libgsl.a, which I want to make use of in my .dll that I write in VC++. How can I actually force compiler to link it? I tried adding the path to additional library path, but I still get the "unresolved external symbol" error...

Try to use #pragma directives
The following pragma causes the linker to search for the Test.Lib library while linking. The linker searches first in the current working directory and then in the path specified in the LIB environment variable.
#pragma comment( lib, "Test" )
Knock out "T" from CAN'T
You 'CAN' if you think you 'CAN'

Yes by default all these handlers are disabled unless you activate it through the command_UI handler .check enablemenuitem.
// try insertmenu or insertmenuitem

Hi FlyWithYou,
maybe it is some helpful to you
#define IDC_TEST 1000
HMENU hmenu,hMenu2;
hmenu=GetMenu(hWnd);
hMenu2=GetSubMenu(hmenu,0);
AppendMenu(hMenu2, MF_STRING|MF_ENABLED, IDC_TEST, "111");
case WM_COMMAND:
switch (wmId)
{
case IDC_TEST:
MessageBox(hWnd,"test",NULL,MB_OK);
break;
...

I tested for your question(why the menu item is gray and disabled, cannot click)
I write this code then test it and it's not gray
do you use this code?

Hello,
In addition to catching the WM_CLOSE event, I would like to disable the close icon on the dialog title bar when some critical section is being parsed in my application.
Is this possible?,
For those that use Nero Burning Room, when you are burning a CD/DVD, the close icon on the dialog title bar is dissabled.. How can be this done under MFC?

I guess that the style of the window is changed with SetWindowLong(), but I don't manage to find how.
Thanks in advance.

disable the related menuitem in the system menu and the button will be disabled at the same time...
|
|
|
|
|
|
GetSystemMenu(FALSE)->RemoveMenu(SC_CLOSE, MF_BYCOMMAND);
|
|
|
|
|
RemoveMenu or ModifyMenu.

I am a novice c programmer. My programs are very floating point intensive - some can take days to run. Most of the CPU time is spent in long loops doing various tasks. I would like to know what the best way of optimising this sort of program for dual cpu processors is. It would be possible to break the loop into 2 bits. I'm guessing it has something to do with multithreading.
Do dual cpu machines automatically distribute the load without specific coding?

Windows does distribute threads of execution between multiple processors. You need to be careful, however. If your algorithm requires that you use thread synchronization primitives like critical sections, mutexes, or other types to synchronize the two threads, your application can end up running slower.
