If recall correctly Zero Memory is a memset that fills 0's in the destination adress.

Yes, but Joaquín told us it was a macro rather than a function. That's why I found it so odd to get different results on the memset/ZeroMemory.
Apparantly it is never safe to do even the simplest performance testing in a Debug build. Lesson learned.

Yeap, Joaquin is right

The allocation of memory is monitored in debug builds by the CRT , so it fakes the results ...
Actually ZeroMemory is a macro using the RtlZeroMemory that is also a Macro that uses ...

WTF?????
ZeroMemory sub contracts the work out to RtlZeroMemory? I didn't authorize subcontractors!!!!

And guess what ? The RtlZeroMemory does a simple memset !!!!
#define RtlZeroMemory(Destination,Length) memset((Destination),0,(Length))

Also consider the fact that you can use intrinsic versions of the memset(...), memcpy(...), etc. functions.

Hi,
does anyone have some idea, how to make some TCP network transfer in separate thread (open connection, send/receive some data, close connection, end thread) using WinSock 1.1, so that i can immediately stop thread from parent thread anytime ?
|
|
|
|
|
One approach is this: launch a thread provided with a message pump, and use message-based asynchronous sockets (see WSAAsyncSelect for further info). This thread can be stopped at any time with PostQuitMessage.

Hello,
I want to do drop file support for my window.
But I'm not able to identify if file(s)
droped on it was drag "with right or left mouse button".
(I would like to do popup menu in case of right button)
Is there any way how to solve it?
Thank you.

From MSDN ,
HRESULT DragEnter(
IDataObject * pDataObject,
//Pointer to the interface of the source data
// object
DWORD grfKeyState, //Current state of keyboard modifier keys
POINTL pt, //Current cursor coordinates
DWORD * pdwEffect //Pointer to the effect of the drag-and-drop
// operation
);
grfKeyState
[in] Current state of the keyboard modifier keys on the keyboard. Valid values can be a combination of any of the flags MK_CONTROL, MK_SHIFT, MK_ALT, MK_BUTTON, MK_LBUTTON, MK_MBUTTON, and MK_RBUTTON
So as u can see you can test for the mouse button being pressed by anding
//left button
if( grfKeyState & MK_LBUTTON )
{
//Do for left button
}
if( grfKeyState & MK_RBUTTON )
{
//Do processing for right button
}

hi,
I am a new socket programmer, I know that socket allow sending buffer of char by send(), if I wont to send a struct or whole class, how I do it?I wish do it by basic socket, then by MFC class.
in reality, I have an application that I would make it work on network, it is installed one several machine , one machine ( the master) send to the others data (object, commend)and the result is sent to this machine,
thanks.

You can send() your struct/class as raw bytes. sizeof will tell you how many bytes. And at the other side you must recv() that many number of bytes into a pointer to your struct/class cast to a byte *

thanks,
If my struct is:
struct X{
int..;
char*..;
..
};
struct X Y;
and I woul send Y by send(),how i send it as raw bytes, i cast it: send(socket,(byte *)Y,sizeof(Y),0)?
and wen I received it I will recost it:
....
int i=recv(socket,buf,..)
struct X* pX;
pX=(struct X*)buf;
...?

That should work BUT ONLY IF your struct DOES NOT HAVE ANY pointer members. In your case you seem to have a char*. Replace char* with a char[].

Read the file and store it as a string in database and store its extenstion in another record.

What kind of datatype do you use in the SQL Server then ??
regards
Henrik

It depends on the type of file, for a plain text file i'd use MEMO or TEXT, if it was a binary file your best bet would be BLOB or BINARY.
I'm not sure if these are the MS SQL Server types or one of the many other DB's i've used
