Why don't you take a look to OnMouseDown and OnMouseUp?
You can look at coordinates of the button or sincronize with OnButtonClick.
Between the time of both mouse messages you have your "Clicking".
For example: I make a drag and drop to move graphical elements in my screen. When left mouse down I check if it hits the surface of any element. If yes... i save the name of the element and set TRUE in a bool "allowDrag". When the left mouse button is released, I search for the element of the saved name, I change its coordenates, and reset to FALSE the allowDrag.
Is something like this what you were asking for?

I think you need to look at check boxes. You can set them to a button-like style.
So when you click once, it goes in and sends a message.
Click a second time, it goes out and sends another message.

Hi!
I'm writing just in case someone might help me.
I'm to finish a huge program code using MS Visual C++ Express 2005
The problem is that I want to use a win32 function(compatible with VC++ compiler) of the equivalent linux function FCNTL(). These are some my code lines:
Sock_handle_t Server::connect ( const char * name, bool nonblocking ) <br />
{ <br />
struct addrinfo *list = NULL, *first; <br />
<br />
list = getaddrinfo_fromtext ( SOCK_STREAM, IPPROTO_TCP, name ); <br />
if( ! list ) <br />
{ <br />
throw fatal_exception(); <br />
} <br />
<br />
Sock_handle_t sock = create_socket ( AF_INET, SOCK_STREAM, IPPROTO_TCP ); <br />
int fd = sock->fd; <br />
if ( nonblocking ) { <br />
<br />
int flags = fcntl(fd, F_GETFL, 0); <br />
if (fcntl(fd, F_SETFL, flags | O_NONBLOCK) < 0 ) return 0; <br />
} <br />
<br />
bool connect_ok = false; <br />
first = list; <br />
while (list) <br />
{ <br />
if( ! ::connect (fd, list->ai_addr, (socklen_t)list->ai_addrlen) || errno == WSAEINPROGRESS ) <br />
{
memcpy ( &sock->address, list->ai_addr, sizeof (sockaddr_in) ); <br />
connect_ok = true; <br />
break; <br />
} <br />
list = list->ai_next; <br />
} <br />
<br />
freeaddrinfo(first); <br />
if(! connect_ok ) <br />
{ <br />
close (fd); <br />
throw fatal_exception(); <br />
} <br />
<br />
return sock; <br />
} --------------------------------------------------------------------
I'm trying to do something like this with those two lines:
int flags = ioctlsocket(fd,F_GETFL,0);
if (ioctlsocket(fd,F_SETFL,reinterpret_cast<u_long*>(flags |_O_NOINHERIT))<0) return 0;
..........but I think it's not ok, any sugestion?
|
|
|
|
|
Here's my cross-platform code for Windows / Linux to set a socket as non-blocking (error checking omitted)
#ifdef WIN32
ulValue = 1;
ioctlsocket (m_hSocket, FIONBIO, &ulValue);
#else
iValue = fcntl (m_hSocket, F_GETFL);
iValue |= O_NONBLOCK;
fcntl (m_hSocket, F_SETFL, iValue);
#endif

hi, all,
I wanna know which function is better to use.
Objectif:
i have a FormView in which i use to add some data into a ComboBox before displaying the Form. So i hesitate beteween the OnInitUpdate , PreCreateWindow and WM_CreateWindow.
So which one is the adequate one?
Thx

If you're going to add items to the ComboBox, you only choice of the three you mention is OnInitialUpdate.
The ComboBox window doesn't exist during PreCreateWindow or during Create. Only after the call to CFormView::OnInitialUpdate does the ComboBox window actually exist (valid hWnd).
Hope that helps.

guys read it carefully
i hav provided odbc connection with an access db1 file
and prepared a ATM project
and used the object m_pSet in all the new classes of dialogs created by me
by passing object of view class as an arguement wen it calls dialog (on button click)
now the problem is
database updation doesnot occur wen we withdraw the money or deposit
it says database updation failed
simply how can v update data frm other class else then view

So is your view derived from CRecordView? Is more than one table involved?

Without a relevant code snippet, it would be impossible to say.

Prior to updating the record, have you called the CanUpdate() method?

Hello,
Currently, I am using LoadImage() to get a handle to an icon that is a resource in my Win32 Application project (using VS2005). Now though, I've added more icons to this icon resource...I now have 3 icons within it, each of 16x16 size, but of different colors (a normal, highlighted and disabled icon).
It looks like LoadImage() is the preferred function to use, but I can't figure out how to extract an icon with a specific index from my icon resource.
Functions like ExtractIcon(), etc. need to be supplied with a path to an .exe, or .ico. I just have it as a resource in my app (ie: IDM_RESET).
Any ideas on the best way to get the icon I want?
Thanks,
|

The original screen is in MemDC

OnMouseMove is a message handler, you need to read the MSDN understand the messaging. The messages come out of the queue and get handled...
Drawing has to be done in OnPaint().
