Hey Friends
I am calling the function get_images but finally i could not figure out it's path
Need Help.
Regards
IHTMLElementCollection* pColl = NULL;
hr = pHtmlDoc->get_images (&pColl);
..
long nLength = 0;
pColl->get_length (&nLength);
for (int i = 0; i < nLength && bSearch; i++)
{
hr = pElemDispatch->QueryInterface (IID_IHTMLElement, (void**)&pElem);
if (SUCCEEDED (hr) && (pElem != NULL))
{
//I got an Image but how to read it?
//Could not find even its path??
}
}

Did you try querying the interface for IPicture? Also, I didn't see any code for getting pElemDispatch from pColl.

hi.. my program is about to capture the dektop by creating compatible dc and compatible bitmap and than convert it from ddb to dib. But I want to compress it before storing it in DAT format. How to proceed with this

Since you mention a specific format (DAT), it is unclear if you mean that you want to scale the image before storing it, or if you really mean data compression.
Scaling can be done in a coarse fashion by drawing the image to a target DC with reduced target width and height values. GDI+ offers functions that may make a better quality image, as will a dedicated graphics library.
If you really mean data compression, which should happen after the image is first converted to its target format (DAT?), then you can use a library like ZLIB[^].
Lastly, if you meant tape backup (or other offline/removable storage) when you said "DAT", then ZLIB helps there, too.
Peace!

Actually Floppy Drive doesn't work the way CD Drive work. I mean, you could simply put Floppy in the drive, but to make Computer aware you have to click on floppy icon, which is not in case of cd drive. thats just my logical conclusion!

But you have to poll regularly for that.. i don't think thats good design and could present user headache, as if floppy is corrupt, it could hang the system!

PC floppy drives have (or used to have) a active low Disc Change line, which went high (1) when the drive was empty and was low (0) when a disc was inserted.
Not sure if/how you can get direct access to that line on Win32, though...
Maybe there is an LVM routine that can be used?
Peace!

Any thing for you sir 
Actaully I tried this for one of my project requirment. I used the ExecNotificationQueryAsync() function with the following query.
HRESULT hres = pSvc->ExecNotificationQueryAsync(<br />
_bstr_t("WQL"), <br />
_bstr_t("SELECT *" <br />
"FROM __InstanceOperationEvent WITHIN 1 "<br />
"WHERE TargetInstance ISA 'Win32_LogicalDisk'"), <br />
WBEM_FLAG_SEND_STATUS, NULL, pStubSink );
And in the notification handler we can check the instance is __InstanceCreationEvent and __InstanceDeletionEvent for any drive arrival or removal. But if you want disk arrival or removal you may need to handle the __InstanceModificationEvent( this one i didnt check ).
