Hi
If you have implemented a new dialog (a child of CDialog) with the functions from the Visual Studio, you have in this dialog-class a message_map and you don't must implement a new message_map.
For Windows messages use the class-wizard to create the handle-functions e.g. OnCreate() for WM_CREATE (see below in the message_map -> ON_WM_CREATE())
For your own messages use the macro ON_MESSAGE in the excisting message_map
e.g.
BEGIN_MESSAGE_MAP(CMainFrame, CMDIFrameWnd)
ON_MESSAGE(WM_OWN_MESSAGE, MyOwnFunction)
//{{AFX_MSG_MAP(CMainFrame)
ON_WM_CREATE()
.....
END_MESSAGE_MAP()
If your dialog complete without MFC, use the windowproc()-function

Hi Guys!!
I want to check Internet connectivity on my machine. I`ve reproduced my code below.
The code works fine except if IE is in offline mode.i.e i am unable to detect offline mode..
#include "stdafx.h"
#include "Wininet.h"
int APIENTRY WinMain(HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPSTR lpCmdLine,
int nCmdShow)
{
BOOL bConnected = FALSE;
DWORD dwFlags;
bConnected = InternetGetConnectedState ( &dwFlags, 0 );
if ( bConnected )
if ( dwFlags & INTERNET_CONNECTION_OFFLINE )
bConnected = FALSE;
if (bConnected )
MessageBox(0,"WOW ! Internet is Connected !","",0);
else
MessageBox(0, "Oops ! Internet is not Connected !","",0);
return 0;
}
Regards!!
Abhi
P.S Tony, Ryan please have a look.

Isn't bConnected false when InternetGetConnectedState returns? What is the return value?
Let's ignore bConnected for a moment.
Change these lines:
if ( bConnected )
if ( dwFlags & INTERNET_CONNECTION_OFFLINE )
bConnected = FALSE;
to:
if ( dwFlags & INTERNET_CONNECTION_OFFLINE )
bConnected = FALSE;
and tell me what happens. What is the value of dwFlags?

Ya the bConnected value is false in Offline mode too.
I tried by removing the condition [if(bConnected)] but still does not work.
The value of dwFlags "in disconnected and Work offline mode" is 16
while in connected mode it is 18.
Do u have any clue?

If bConnected is false then it means that the internet is not connected (but I believe that you know that already). I thought you were getting bConnected = TRUE, even though you were offline. That's why I asked you to remove [if(bConnected)] just too see what would happen. You shouldn't get worried about the dwFlags value. I bet you want to know why the dwFlags doesn't have the INTERNET_CONNECTION_OFFLINE flags set? Sorry, but I don't have an answer for that.
To wrap things up, your code works fine.

Hi all,
I want to create an application in VC++ and have the following question.
1. Which project type i should choose, whether MFC.exe or AppWizard.
2. After creating interface, User should login to application. This login user id and password at the value avaible in database(MSaccess). Here say on OK action i create CDatabase Instance and open the database.
I want to use this instance for the rest of dialog to open other tables in the database. My question is how to make it gobally avaible.
Can someone point to me a link or good site. I am beginner in this language.
Thanks in advance,
Regards
Valli

Make your CDatabase instance a member of your CWinApp derived class. You can then access it anywhere in your project by using AfxGetApp.

I want to shutdown the other PC through programatically. All PC r already connected through network.
If we can shutdown one PC which is WN2000 and other is WNME.
If anyone know Plz tell me.
|
|
|
|
|
ExitWindowsEx( EWX_SHUTDOWN, 0 ).
Check out the other flags that this function uses as well because I am just giving you an example, which might not always apply to your case.
You can also check InitiateSystemShutdownEx.

I want to ask one more question.
If we can shutdown one PC which is WN2000 and other is WNME. Both of them r connected through network
If anyone know Plz tell me.

To shutdown another PC, use InitiateSystemShutdownEx(), but this only works for Win2k/XP PCs. You can't shutdown a remote Win9x/ME system without writing a server that runs on that machine and communicating with the program over the network.
Hope this helps,

I should start reading the questions more carefully. He is asking how to shutdown a computer through a network and I didn't even get that part!!!

Hi, Everyone
I want to know that what is the difference between DLL and LIB file.
Or There is similarity between DLL and LIB file.
Also tell me Dynamic and static DLL.
|
|
|
|
|
DLL is for 'Dynamic link library'. This means that it contains executable code (!!) that can be loaded at run time. So, you don't have to include your dll in your project when compiling.
The lib is in fact a 'static link library'. This means it contains functions (!!) that can be loaded at linkage. So, you need to include your library in the project when compiling your program.
For the static library, the functions within the library will be 'pasted' in your own program so you don't need the library with your executable. For the dll, when you execute your program, it will search for the dll, and execute code from within the dll. So you need to provide the dll with your executable!
BTW, I never heard about static dll.
Hope this helps

I think by dynamic and static dll, he meant dynamically or statically linking to a dll.
I don't think there is any such thing as a dynamic or static dll.
In dynamic linking to a dll, you don't require the lib file, whereas in static linking you require the lib file.

Go to http://webopedia.com/TERM/l/library.html[^].
From there on, browse through linker, runtime, DLL, compiler, etc...

Nothing easier than this
