Hi,

I am writing a setup program and I want the user to install the latest
version of, let's say, unidrv.dll, from the Windows installation CD. How
would I prompt the user to insert the CD, get the file and ask them to
reboot if neccessary?

If anyone can help me, I really appreciate it.

Thanks,
Sinping

Your install program should check:
1) First locate which drive is the CD-ROM. You use  the GetLogicalDrives or the GetLogicalDriveStrings functions to know which drive letters are available.
2) Use GetDriveType to know which one of the drives is a CD-ROM
3) You must know the VolumeLabel of the CD, in order to know if the correct CD is in the Drive. This can be done using the GetVolumeInformation function.
4) If the wrong CD is in drive you prompt the user with a MessageBox to insert the correct CD (When the user presses OK you go back to step (3) until the correct disk is in the CD-ROM.

Optional and Extreme Luxe: How do you know when the Cd door is closed?.. Well, you catch the WM_DEVICECHANGE message with the DBT_DEVICEARRIVAL      parameter (wParam). This will notify your app when a new disk has been inserted in the CD-ROM.

5) You do your necessary file operations, reading from the CD and writing to the Hard Disk.

------------ To reboot
If you decide that the changes made by the Setup program need the computer to rebbot you must use the ExitWindowsEx fucntion with the EWX_REBOOT flag in the first parameter.

I hope to have helped you. I fyou need more help, tell me... also if you need the declarations for the functions I mentioned (you can find the in your developmnet tool help files)

Your answer is helpful. However, for different OS, the layout of the CDs are different. How will I know where on the CD to look for the file? For example, Win98 CD has all those Win98.cab files.

Is there a particular SDK function to perform the update? On Win95, Win98 and Win NT?

Not that I know, I think you have to build some algorithm to detect all the cabinet files in the CD
