Yes it does, it is the last argument of the Create function (so, it is 1001). In general it is better to reserve the ID in the resource file, so that when you add another control through the resource editor, the same Id won't be reused.

Where do you filter out the checkbox change? As i understood, you want the combo-box appear/disappear thing when the user checks or unchecks the checkbox of the list item. OnItemChange gets called also when the item's selection or focused state changes (and maybe some other cases i'm right now not aware of or am not thinking of). Should this code run for every possible state change?

yes,the code change every possible state.when we check combo should appear,when we uncheck combo should not appear.in case double click checkboxes state becomes uncheck so combo should not appear but in my code when double click check box becomes uncheck its fine but combo appearing.pls solve my problem.

You need to EnumFontFamily or EnumFontFamilies for enumerates fonts and CreateFont/ for images you can use of CImage class for load and show them.

Hello,

I am looking for information of present drives on the system.
I am interested to get information of each drive present on the system which includes -
1) Model,
2) Serial number,
3) Type
4) Solid state drive status, etc.

Now, I am able to get such information for hard disk's drives. But not able to get this information for other drives like CD-ROM, USB drives, etc.

I am using CreateFile method to locate that drive and pass the handle to DeviceIoControl method which gives me listed info for Hard disk drives only. The DeviceIoControl gives me blank buffer for other drives like CD_ROM and USB, etc.
I am using code to locate drive as -

HANDLE hDiskDevice = CreateFile(DeviceName, 
			GENERIC_READ| GENERIC_WRITE, 
			FILE_SHARE_READ | FILE_SHARE_WRITE,
			NULL,
			OPEN_EXISTING,
			0,
			NULL);

To fetch information from the system, I am using -

DeviceIoControl(hDiskDevice, 
                           SMART_RECEIVE_DRIVE_DATA, 
                           pInputATABuffer, 
                           InputBufferSize -1, 
                           pOutputATABuffer, 
                           OutputBufferSize -1, 
                           &BytesReturned, NULL)

Please let me know if you have any ideas to get such information for USB, CD-ROM, etc drives.

Thank you.

With regards,

Shashikant

Looking at documentation, I suppose SubclassDlgItem is just a shortcut to the sequence

HWND  hMyCtrl  = GetDlgItem(IDC_MYCONTROL);
SubclassWindow( hMyCtrl );

If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.
