A Solution is to create a remote thread in explorer that just start do the work when it detects a M_QUERYENDSESSION

The problem with the WM_QUERYENDSESSION message is that an application can return 0 in response to it and Windows will not shut down.

Exactly what he may need if he want to do some processing and then call the ExitWindow family of API

If, during the processing of the WM_QUERYENDSESSION message, a call is made to ExitWindows[Ex](), does that not re-send the WM_QUERYENDSESSION message?

As I read Alex's original post, he was interested in doing something if Windows was shutting down, not if Windows was asked to be shut down. If work was done during the processing of WM_QUERYENDSESSION, it is not guaranteed that Windows will shut down, thus the processing may be immature.

so, as i understand Alex's question (or even if it is not his, it's mine Big Grin | :-D

), is there a way to lauch a program which is not executing when windows shuts down (and so don't use memory for nothing - because it is not needed before the loggout) ?

the problem is, when you catch the WM_ENDSESSION , the program must be currently running to catch the event...

Hi world...

What is the most useful way to change language in an application?
I've read we can do that with explicit link for DLL (one DLL for each languages ressource). Example:
- exported from french.dll file:

extern "C" __declspec(dllexport) char* get_text(int id_text);

- int the application:

typedef char* (MY_FUNCTION)(int);
HINSTANCE hInstance;
MY_FUNCTION *pFunction;
VERIFY(hInstance = ::Loadlibrary("c:\\winnt\\system32\\french.dll"));
VERIFY(pFunction = (MY_FUNCTION*) ::GetProcAddress(hInstance, "get_text"));

int id_text = 5427
char* good_translation = (pFunction*)(id_text);

Is that a good solution?

Thanks for your suggestions...

Drawing anti alias Lines and Curves

Hi,

Does anyone know how to draw anti aliased lines and curves using MFC?
I've been playing with CDC::LineTo() and CDC::Pie(), etc but none of them produce the results I was looking for.

Any help would be appreciated.

Thanks,

Have a look at the GDI+ routines. It has a SetSmoothingMode() function that antialiase lines and circles.

put that in the first dialog
const unsigned int wm_uiImportDone=RegisterWindowMessage("Import_Done");

give wm_uiImportDone as a pointer to the class

on the class, mae sure to add that to the message map
ON_REGISTERED_MESSAGE(wm_uiImportDone, OnImportDone)

then on the dialog, use:
::PostMessage (m_hWnd, wm_uiImportDone, 0, 0);
when m_hwnd is a pointer to the class that has to be derived from a window to get a message

Updating Dialog from a thread

Hi,

Let's say I have a CStatic control that is represented by a CString (m_str_status) which I pass to a working thread.

I want the thread to change this status while it works, and of course show it on the dialog....

THE PROBLEM IS --->Even if I pass a pointer to the dialog to the thread, UpdateData function is illegal and will cause an exception.

How do I force the dialog to update itself after I changed the value of the status string ?

Several options
1. Send a message to the dialog
2. Call a function of the dialog that takes the new string and update it
3. Signal an event ...

post a message to the dialog to indicate the status string change.

It's not a bug, it's an undocumented feature.

One of the precautionary don'ts that get repeated when it comes to multi-threaded programming is never, ever, directly interact with a control using another thread.
This nice introductory article explains this[^].

Personally, if I need visual updates via a separate thread, I would post user-defined window messages to the displaying dialog.

How many times DLL loaded for different Application?

hi all,

I am new to DLLs. I have one doubt on dll loading.

if two or more different applications use a same dll. how many instance of the dll will be loaded in memory.

My Question is whether each application will has its own instance of the dll. or just one instance of the dll will be loaded and all applications have its mapping to the single instance.

please clarfy me.

thankyou in advance

The code will have one instance but data will have one instance for each appliction that is using the dll. You can use a shared data segment to share data between processes if you want, in this case this data will only have one instance.
