you did forget the __int64
struct TBTAddr{
unsigned __int64 _address:48;
};
This works like you intended

However, why not just use a bluetooth address ?
#include <ws2bth.h>
typedef ULONGLONG BTH_ADDR, *PBTH_ADDR;
typedef struct _SOCKADDR_BTH
{
USHORT addressFamily;
BTH_ADDR btAddr;
GUID serviceClassId;
ULONG port;
} SOCKADDR_BTH, *PSOCKADDR_BTH;
... i guess you mean you are modifying SOCKADDR_BTH::btAddr directly.

Can we Implement Multiple Inheritance in vc++. If yes How.
infotechtata
|
|
|
|
|
|
Even for the class derived using Cobject it doesnt support
infotechtata
|
|

Cobject doenot not support multiple.So it's derived class cannot support multiple inheritance otherwise the previous line will contradict.
if want then go for non Cobject base class
|
|
|
|

don't ask for VC++ but for MC++ (managed C++) so...
as Visual C++ is standard complient, multiple inheritence is of course supported.
now, as C++/CLI target is the .NET framework, i think they limited this point to allow MC++ to coexist with other .NET languages.

Hi,
when you resize a column in list control which event gets triggered?
|
|
|
|
|
OnBegintrack and OnEndtrack
|
|
|
|
|
How to add those event handlers?
|
|
|
|
|
<br />
BEGIN_MESSAGE_MAP(GridClass, CListCtrl)<br />
...<br />
<br />
ON_NOTIFY(HDN_BEGINTRACKA, 0, your_OnBegintrack)<br />
ON_NOTIFY(HDN_BEGINTRACKW, 0, your_OnBegintrack)<br />
ON_NOTIFY(HDN_ENDTRACKA, 0, your_OnEndtrack)<br />
ON_NOTIFY(HDN_ENDTRACKW, 0, your_OnEndtrack)<br />
<br />
END_MESSAGE_MAP()<br />
Note, that the control id of the CHeaderCtrl in CListCtrl is always zero;
thus, the second parameter (that is the control filter) in the ON_NOTIFYs is zero.
The "A" and "W" versions are for ANSI and UNICODE (Wide) environment;
in any given program run, only one or the other will become active.
Btw, OnBegintrack receives control, when the user grabs the right-side divider of a column with the mouse (starting resizing). OnEntrack receives control, when the user releases the divider.
The parameters are:
void yourClass::your_OnBegintrack(NMHEADER *nmheader, LRESULT* pResult)
void yourClass::your_OnBegintrack(NMHEADER *nmheader, LRESULT* pResult)
(*nmheader).iItem is the column index from zero.
*pResult should be set to TRUE if you don't allow resizing (TRUE indicates, that you processed the event completely), and FALSE, if you want MFC to finalize resizing.

|

No this is not working?
Actually I want to resize a control in list subitem as I increase or decrease
column width.I am handling this in OnCustomDraw() but it is flickering.I want to set SetRedraw() to TRUE and FALSE but in which event should I do that?

CxImage is very Heavy Class. it wil add around 200 to 400 kb to your code depending on Option selected. Better use CEnBitmap by Mr Dan.g. it's is nice CBitmap derived class for Popular Image Format.
here is link for that: -

I have studied the article "Serical Communication in Windows".
It talk about the event driven in Com port, but the reading process of demo program is driven by button.
I would like to know how to do event driven in this demo program.
For example: Automatically detect the com port input data and display the data in the Edit box.
Please help!

Hi,

If u r planned to implement serial communication in GUI based application then do read,write... operations in separate thread.

you should go to artical and search for authors: konchat, Ramon de klein, Ashish Dhar. I think you will find many choices for you. I got problem like you a month ago. Cheers.

I tried to post on CodeProject today but "Too many users are trying to ... the server" so i posted the same problem on CodeGuru.com also. My problem is that in linux as super block of ext2 file system is placed in 2nd block of floppy which starts at 1024 and also name of file sytem is written on 57th and 58th bytes of super block so I have written following code to check the file system on floppy but this code is not giving me any output. Can anyone tell me what is problem.
HANDLE fp;<br />
short int data = 0;<br />
DWORD count;<br />
fp = CreateFile ("\\\\.\\a:",GENERIC_READ,FILE_SHARE_READ,NULL,OPEN_ALWAYS,0,NULL);<br />
SetFilePointer(fp,1024+56,NULL,FILE_BEGIN);<br />
ReadFile(fp,&data,2, &count, NULL);
cout <<data;

Good morning.
The argument to SetFilePointer() HAS to be an even multiple of the sector size. In your case (a diskette), the sector size is 512.
In fact, ALL operations on a disc device is done on one (or more) complete sector(s) at the time. This goes for seek, read and write.
So:
First, set the file pointer to an even mutiple of 512, in this case it will be 1024.
Then, read a complete (or more) sector(s). A sector is the smallest bit of information a disk device can handle.
Try this:
<br />
HANDLE fp;<br />
short int data = 0;<br />
DWORD count;<br />
unsigned char buffer[512];<br />
fp = CreateFile ("\\\\.\\a:",GENERIC_READ,FILE_SHARE_READ,NULL,OPEN_ALWAYS,0,NULL);<br />
SetFilePointer(fp,1024,NULL,FILE_BEGIN);<br />
ReadFile(fp,buffer,512, &count, NULL);
data = *(buffer + 56);<br />
cout <<data; <br />

1. How can I display an image, like an image editor, in full screen mode?
2. What is the fastest method displaying an image (both in window or in full screen)? Some programs work much faster than others; scrolling an image takes much longer with some programs than with others.
Thanks
