You can't. You need a IXMLDOMDocument to create an XML file.

I want to check that in target machine already register somefile.OCX or not.
How can I write the code for this issue?
Thanks

Hi
you have to check that in the registry;
so write code for that
|
|
|
|
|
If you know the relevant GUIDs you can call CoGetClassObject or CoCreateInstance and check the return value.

I have some code below, which uses the disk management code IOCTL_DISK_GET_DRIVE_LAYOUT. However, when I run the application, the error code 122 is produced (indicating that the DRIVE_LAYOUT_INFORMATION structure - which is pointed to - is too small). How would I rectify this problem?
Here is the code below:
<br />
BOOL GetDriveLayout()<br />
{<br />
BOOL bResult;<br />
DWORD dwRet =0;<br />
DRIVE_LAYOUT_INFORMATION p;<br />
<br />
bResult = DeviceIoControl(hDevice,IOCTL_DISK_GET_DRIVE_LAYOUT,NULL,0,&p,sizeof(p),&dwRet,NULL);<br />
<br />
if(bResult==FALSE)<br />
printf("Error: %d", GetLastError());<br />
<br />
return bResult;<br />
}<br />
Note that other IO functions such as IOCTL_DISK_GET_PARTITION_INFO work fine..
Thanks for your help!

Depending on your OS version you could need to use DRIVE_LAYOUT_INFORMATION_EX which is documented here[^] and IOCTL_DISK_GET_DRIVE_LAYOUT_EX. You might want to consider using IoReadPartitionTableEx[^] to retrieve the partition information as well.
Nothing is exactly what it seems but everything with seems can be unpicked.

Thanks  I sorted the problem out myself but I have used DRIVE_LAYOUT_INFORMATION_EX now instead aswell

and i frequently chane only (200,200,500,500) region rest remain unchange.
How InvalidateRect is useful? whether it redraw whole CRect(10,10,1000,1000) or just (200,200,500,500) on each OnDraw call..

just (200,200,500,500), as stated here [^]:
Before BeginPaint returns the display device context, the system prepares the device context for the specified window. It first sets the clipping region for the device context to be equal to the intersection of the portion of the window that needs updating and the portion that is visible to the user. Only those portions of the window that have changed are redrawn. Attempts to draw outside this region are clipped and do not appear on the screen.

Hi!
I have a problem in retrieving printer information using FindNextPrinterChangeNotification() function.My code executes properly without any error and exception but all the values in LPPRINTER_NOTIFY_INFO structure are NULL or zero.code as follow
LPPRINTER_NOTIFY_INFO notification;
LPPRINTER_NOTIFY_OPTIONS notifyoption;
notifyoption = (LPPRINTER_NOTIFY_OPTIONS)HeapAlloc (GetProcessHeap (), HEAP_ZERO_MEMORY, sizeof(PRINTER_NOTIFY_OPTIONS) );
notification = (LPPRINTER_NOTIFY_INFO)HeapAlloc ( GetProcessHeap (), HEAP_ZERO_MEMORY, sizeof(PRINTER_NOTIFY_INFO) );
OpenPrinter("HP LaserJet 3200 Series PS",&hprinter,NULL);
if(hprinter == INVALID_HANDLE_VALUE)
MessageBox("printer not available","",MB_OK);
hnotify = FindFirstPrinterChangeNotification(hprinter,PRINTER_CHANGE_ALL,0,notifyoption);
notifyoption->Flags = PRINTER_NOTIFY_OPTIONS_REFRESH;
if(hnotify == INVALID_HANDLE_VALUE)
MessageBox("Invalid handle hnotify","",MB_OK);
DWORD retcode = WaitForSingleObject(hnotify,INFINITE);
if(retcode == WAIT_OBJECT_0)
{
BOOL ret = FindNextPrinterChangeNotification(hnotify,&changeNotify,notifyoption,(LPVOID*)notification);
if(ret !=0)
{
if(notification->aData[0].Type == PRINTER_NOTIFY_TYPE)
MessageBox("printer notification","",MB_OK);
sprintf(msg,"Field=%d",notification->aData[0].Field);
MessageBox(msg,"",MB_OK);
if(notification->aData[0].Field == PRINTER_NOTIFY_FIELD_SERVER_NAME)
{
MessageBox("Printer Name is","",MB_OK);
memcpy(printername,(char *)notification->aData[0].NotifyData.Data.pBuf,notification->aData[0].NotifyData.Data.cbBuf);
MessageBox(printername,"",MB_OK);
}
else
MessageBox("other than printer name","",MB_OK);
FreePrinterNotifyInfo(notification);
}
else
MessageBox("error in executing","",MB_OK);
ivalue of Field and cBuf is NULL
please if anyone can identify the problem..it will be very helpful for me
Thnaks in advance

Could it be because you appear to have not set the Version field of the 2 PRINTER_NOTIFY structures? MSDN recommends setting the Version to 2 see here[^]

Hi
consider the function
void ClassName::Fun()const
{
//Here we cant change the value of the datamember
}
Is there any benefit of using the const member function.Like Performance benefit.

Generally const function are GetXXX methods, which will return only values. It ensures that the data members will not be changed by mistakenly.
Declaring a member function with the const keyword specifies that the function is a "read-only" function that does not modify the object for which it is called.

Paresh.

The benefit is that the code is more expressive and less error prone. If you pass a const reference to one of these you gaurantee that only const methods can be called through that reference

Oh, yes.
Suppose you have to pass an object of class A (say a) to an object of class B (say b) only to informative purposes, i.e. you don't want b to change a. You may, for instance, pass a itself as const A & this automatically allows b only to call const member functions of a. That is the trick: if A has no const member functions, then the const A & is useless.
Hope that helps.
