Perhaps I'm old school, I prefer a real book that I can read and make notes in while I'm drinking coffee on my patio.

Hi.
The CFindFile class can help to finding a file/directory.
you can get more information about this class from MSDN library.

How do I resolve an email address such as my_email@yahoo.com into an IP address such as 112.33.152.23?
I know using gethostbyname() resolves URL address to an IP address, but won't do it for email address.
Thanks.

You want the IP of what ? the mail server ? the IP of the end user machine ?
AFAIK, the email address' user part does not "resolve" to an IP, only the domain name. it's the mail protocol that will handle the user management ( on the mail server ), sending the message to the appropriate mailbox.

Dear all,
How can I get such information as head, cylinder, sector... of a specific physical disk in Win98? I currently use the first sector and parse information from partition entries in order to get those information. Are there any better methods?
Best regards.

I'm not sure exactly what you are after, but see if DeviceIoControl(..., IOCTL_DISK_GET_DRIVE_LAYOUT_EX, ...) will help.
Nope, that is for Windows NT-based machines. I'm not sure what will satisfy your Windows 98 requirement (I don't develop for it).

Dear David,
That function requires a handle to device Physical Disk. Unfortunately, in Win98, we cannot create that handle. So the function DeviceIoControl won't work.
Thanks for your suggestion.

Why not?

It's simple. Because the CreateFile() doesn't return a handle.

Sure it does. Check the documentation or the function's prototype.

I did try it. It worked properly in Win2k/XP, but not in Win98. You can make a simple example and test it in Win98. Just create a file with a file name "PHYSICALDRIVE0".

This worked as expected:
HANDLE disk = CreateFile(_T("\\\\.\\PHYSICALDRIVE0"),
GENERIC_READ,
0,
NULL,
OPEN_EXISTING,
0,
NULL);
if (INVALID_HANDLE_VALUE != disk)
MessageBox(NULL, _T("Work"), _T(""), MB_OK);
else
MessageBox(NULL, _T("Not Work"), _T(""), MB_OK);

Does that code work correctly in Win98 platform? If yes, it looks so strange. Let me try it again. Anyway, thank you so much.

Check out the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\policies\system\DontDisplayLastUserName registry key. This won't do anything about a default user, but it does remove the ability to view which user was last logged onto the machine by clearing the username box on the login screen.

I'm not sure if this is possible without a custom GINA.DLL.

By default, after a successful login, the desktop is displayed. I'm not sure what you mean by "ordinary user have no entry to desktop." Perhaps the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows\SecureDesktop registry key might be of use.

Without creating your own MSGINA.DLL, I know of no way to automatically plug "Default" into the login box.

This happens by default. Some windows, such as Windows Explorer and Control Panel, might open back up if they were open when Administrator last logged off.

Then put your application in the Startup group, or the Run key (not in the HKLM hive) in the registry.

hi,
if u put into startup then first desktop will come and after that ur application also will come.
more over from there by using some key u can access the desktop.
In our system only admin have the right to access the desktop, no one else.
so can u send some script for that
bye

Correct. Only services start before the desktop.

Is this handled at the OS level (I've not been able to find anything), or is there a third party utility running that handles this?

I was considering a solution to my problem of grabbing strings from another application. Writing to a file seems to be easiest solution. However, the app which reads the file needs to read it in real time. Both apss run at the same time. The first program is writing data to a file (redirect stdout to a file and use printf). A second program is reading the file and displaying the data in a GUI text window. However, this does not seem to work. It may be a permission problem, but I'm not sure. I thought about using create named pipe, but I want the second app to be optional (meaning it does need to be run). When using pipes, don't both need to be connected? Any suggestions. Thanks.

One solution is memory-mapping. Another solution is WM_COPYDATA.

Hi.
If your data is small you can use windows registery to pass the data.
If not you can use combination of two strategy named pipe and writing to file.
but i think after every write you close the file and open it at other time the second app can wait to close the file and then itself open it.
