use the following code.Here m_letter is the member variable of combo box.

int k = 0;
DWORD MaxDriveSet, CurDriveSet;
DWORD drive, drivetype;
TCHAR szBuf[300];
HANDLE hDevice;
PSTORAGE_DEVICE_DESCRIPTOR pDevDesc;

for(k=0; k<26; k++)
szMoveDiskName[k] = '\0';
k = 1;
// Get available drives we can monitor
MaxDriveSet = CurDriveSet = 0;

MaxDriveSet = GetLogicalDrives();
CurDriveSet = MaxDriveSet;
for ( drive = 0; drive < 32; ++drive )
{
if ( MaxDriveSet & (1 << drive) )
{
DWORD temp = 1<<drive;
_stprintf(="" szdrvname,="" _t("%c:"),="" 'a'+drive="" );
="" m_letter.addstring(szdrvname);

="" switch="" (="" getdrivetype(="" szdrvname="" )=""
="" {

if(GetDisksProperty(hDevice, pDevDesc))
{
if(pDevDesc->BusType == BusTypeUsb)
{
szMoveDiskName[k] = chFirstDriveFromMask(temp);
szMoveDiskName[0]=k;
k++;
}
}

delete pDevDesc;
CloseHandle(hDevice);
}

break;
case DRIVE_REMOTE:// The drive is a remote

i do understand that CComboBox::Dir works. but it working only for the current working directory.. i wnat to list out the total number of directories available on the system.

ya.For that only i have used the above code even though it is little bit lengthy.But it works perfectly.

But it is only for getting the drives, not directories. Am I right?

That's wrong. Try this...

m_combo.Dir( DDL_EXCLUSIVE | DDL_DIRECTORY, "C:\\Windows\\*.*" );

For this case, AFAIK, you have to enumerate the directories. CFileFind class can help you.

it is working. but it is giving all the files and directories that is available in C. my requirment is not that. for example if there are 4 drives..ie(A,C,D,E). i need to print that A.C.D.E in the combo box. nothing else.

What I gave you is only an example. You can call it for any drive. Each call will add the list of directories to the existing list in the combo. If you need to get all the directories, as I said earlier, use CFileFind class recursively.

If you need only drives, specify the attribute as DDL_DIRECTORY.

Wrong. You should use DDL_DRIVES if what you want are drives.

These are drive designators, not directories (as your subject implies).

Send it a CB_DIR message. Use DDL_DIRECTORY | DDL_EXCLUSIVE for the WPARAM argument. If you are using MFC, the solution is even simpler.

Can we get the starting date from which history of IE is displayed in the history folder programatically.

FindFirstUrlCacheEntryEx/FindNextUrlCacheEntryEx specify URLHISTORY_CACHE_ENTRY, you'll have to check every entry and examine the times in the INTERNET_CACHE_ENTRY_INFO to find the earliest time.

An option could be to check main window class using GetClassName.

AfxGetMainWnd()->GetClassName()...

CTaskbarNotifier looking bad on Vista [modified]

Hi,

I've used the CTaskbarNotifier (found here) class in my project to show taskbar notifications. It works fine on Windows XP, but I've just seen that it's not so fine on Vista... The notifications have an ugly border.

You can see it on screenshots:

XP: http://alaf.sierp.net/xp.jpg
Vista: http://alaf.sierp.net/vista.jpg

Any idea how to get rid of that border?

Cheers,
Maciej

To be more specific:

The windows is created with the WS_POPUP style:

CreateEx(0,strWndClass,NULL,WS_POPUP,0,0,0,0,pWndParent->m_hWnd,NULL);

One thing comes to my mind, I don't have the Platform SDK for Vista, I am using the previous one, for Windows XP. Could the lack of Vista SDK be causing incorrect styling?

HELP: split up source file into segments automatically....

This is not really language specific but more of a source code parsing.

I have a large ASP source file that I like to split up, resulting in separate ASP files, each containing one function and the filename named after that function.

Does anyone know of a tool/script which does this?

PS: I am too lazy to learn Perl/AWK/Python to do this, hence why I believe someone has already written a tool/script to do this. Possibly in C++/etc.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
