I would use something like libsigc++[^]. This implements a 'signal-slot' arrangement almost exactly the same as .NET events, but in plain C++.

Thanks for the reply, I'll take a look.

We use sigc++ at work. Once you get past the learning curve, it's very powerful.

Personally, I'd tend to use Boost.Signals, as I know I'll be using other bits of Boost as well. BUt I'm not sure if the new version of that is VC6 compatible, so.

Hello friends
What is the message Notification when we change view in a dialog?
thanks & Regards

What do you mean by "change view in a dialog"  ? There's no "view" in a dialog...
You should really learn to ask a question properly if you want help: all the questions you ask are just so cryptic that a lot of people have to ask you question about what you are trying to do. If you really want help, you should learn to formulate your question so that others can understand you.
The big problem with your questions is that you assume that everybody knows what you are talking about, which is of course not the case. So, next time you ask a question, take the time to introduce the context (what are you trying to do at a high level, not just blindly focusing on the point you are trying to solve). A question like this taken out of its context doesn't mean anything... Keep in mind that we can't see what you are doing.

From the yesterday's post, I guess you want to know the style of the list control while the open file dialog is closed. For that I answered you yesterday.
You will get WM_STYLECHANGED message, when the view of the list control is changed. the applciation is using common control version 6, you will get LVM_SETVIEW message.

Do the open file dialog have windows XP theme?
yogeshs wrote: .I am having the handle of listview But I need some notifiction from where i can get viewtype?
You have to subclass the window proc of the list view and inside that, you have to check for the WM_STYLECHANGED/LVM_SETVIEW message. You can use SetWindowSubclass() function to subclass the window proc.

Have you tried sending the control a LVM_GETVIEW message?

Hi,
Is there a way to configure a CFileDialog so that it displays the files in date order by default without the user having to choose this?
Thanks

I suppose the file format doesn't matter.
See here for sample how to use win32 cryptoapi.

hi all
i want to develop an application in which i need to find unused disk space in a disk. please guide me how it will possible using C++/VC++/MFC
|
|
|
|

Use can use GetDiskFreeSpaceEx API to get the free disk space in a disk. Just refer for more details[^]

Use these functions and get the free space Smile
double funcToGetDriveFreeSpace(LPSTR drive)// give drive name here
{
BOOL success;
CString driveName = drive;
driveName.Append(_T(":\\"));
//LPCTSTR DiskDirectory = _T("C:\\"); // directory name
__int64 AvailableBytes; // number of bytes on disk available to the caller
__int64 TotalBytes; // number of bytes on disk
__int64 FreeBytes; // free bytes on disk
DWORD SectorsPerCluster=0; // pointer to sectors per cluster
DWORD BytesPerSector=0; // pointer to bytes per sector
DWORD FreeClusters=0; // pointer to number of free clusters
DWORD TotalClusters=0; // pointer to total number of clusters
//char FmtNumber[20];
double Size;
char Units[3];
success = GetDiskFreeSpaceEx((CHAR*)driveName.GetString(), (PULARGE_INTEGER) &AvailableBytes,
(PULARGE_INTEGER) &TotalBytes, (PULARGE_INTEGER) &FreeBytes);
if (!success)
{
success = GetDiskFreeSpace((CHAR*)driveName.GetString(), &SectorsPerCluster,
&BytesPerSector, &FreeClusters, &TotalClusters);
FreeBytes = FreeClusters * SectorsPerCluster * BytesPerSector;
TotalBytes = TotalClusters * SectorsPerCluster * BytesPerSector;
if (!success)
{
return -1;
}
}
if (success)
{
fmtsize(FreeBytes,(double&) Size, Units);
return Size;
}
}
void ::fmtsize( __int64 Number, double &Size, char Units[3])
{
const int KB = 1024;
const int MB = 1024*1024;
const int GB = KB*MB;
double DIV;
if (Number>GB)
{
DIV = double(GB);
strcpy(Units,"GB");
}else if (Number > MB)
{
DIV = double(MB);
strcpy(Units,"MB");
}else
{
DIV = double(KB);
strcpy(Units,"KB");
}
Size = Number / DIV;
}
If you like the answer mark this answer as GOOD and close the Thread.

See its not clear what you want to achieve. Give more details on what exactly is your goal, and please spare some time in explaining what have you achieved till now and what is required to be achieved. Please be specific in asking about what you want to do , else its all too vague.
Reagards,

hi
actually i have an Project to do, in that i have to wipe/clean a disk in a manner so that the deleted data of a disk can not be recovered by any Data Recovery Software.
for that i am doing following things -
1. I am reading the disk Sector by sector.
2. then i overwrite some new value on the sector so that the old one can not be recovered.
Now the problem is that in this process the whole disk is overwritten by a new pattern of value.
But actually i do not need this, i need to overwrite the value of only those file that have been deleted already.
so i need to find the deleted files sector.
For Example:-
if there is a deleted file starting at Sector no 2345 to 2356. So how to do it inmy application using VC++/C++/MFC
Thanks
