no reply on this one huh? Yeah, it seems to be a toughie...well just wanted to add some info I think I left out: I'm using file-based access to the port to achieve the communication. I call SetupDiGetDeviceInterfaceDetail to get the device path, and use ReadFile and WriteFile from there on.
So the problem is getting some piece of information from the SetupDi functions (or maybe CM_ functions) that I can match with something that I get from the spooler functions (OpenPrinter, GetPrinter, etc.) The SetupDi functions only give me manufacturer name, model, and serial #.
As I tried to say above, the options as I see them are:
1 retrieve serial # from spooler functions (I can get it from the other side)
2 match virtual USB port in spooler (ie "USB0001") to actual port (maybe "hub#:port#", but any format will do) <-seems more likely option
Just wanted to make sure I was being as clear as possible.
Thanks!

Well, I solved this. All necessary info is in this very long thread[^]"] over at HP forum.

Ok, so what code are you using to initiate the download?

Your post seems comparable to the first post in the forum, "How to get an answer to your question", item #2.

Hi,
How I can get the Physical disk information?
|
|
|
|
|
If you just need the disk size information then use GetDiskFreeSpaceEx(). if you want more details such as tracks, sectors etc, partition info, then DeviceIoControl() will be helpful.
Check control codes such as IOCTL_DISK_GET_DRIVE_GEOMETRY_EX, IOCTL_DISK_GET_DRIVE_LAYOUT_EX etc.
Regards,
Jijo.

Also if you want to get drive type use GetDriveType().
Use such constants:
DRIVE_CDROM = 5<br />
DRIVE_FIXED = 3<br />
DRIVE_RAMDISK = 6<br />
DRIVE_REMOTE = 4<br />
DRIVE_REMOVABLE = 2

I think he want to extract all info about disk (Total space, occupied space, free space, drive letter, file system, is ready, serial number, total clusters, free clusters, total sectors, drive type and volume name).

PC is an IBM brand desktop, 1 Ghz CPU, 512 meg RAM
Sometimes the cursor will stop blinking, the mouse cannot change the cursor position and cannot select text, etc. This will endure for 10 to 20 seconds.
Task manager does not report any high CPU usage.
Task manager reports plenty of unused RAM.
I can switch to another application program and they work fine.
There are times when I can work for an hour without incurring this problem, but there are also times when it seems to happen very frequently.
Any help would be very much appreciated.
Thanks,
Robert

I'm afraid that I was not clear with my question.
The problem is not with the app that I am developing.
The problem is with Visual Studio VisC++ 6.0 environment itself. The cursor freezes while editing source code.
Any help would be appreciated!
Thanks,
Robert

can anyone explain or point me to some link or something where i can
learn how to save/load text from harddisk ?
my project is to make program that can save cooking recipes with their pictures and should have search box where you can type word example "eggs" and somewhere should appear all recipes with eggs
and when i select the title of some recipe example "Fish and chips" in the picture box should apper picture of the meal and in the label or something similar should apper all the ingredients for the meal
my idea is thet i can put the recipes in a list box and search via edit box and i can put simple picture control for the pictures of the recipes where should appear but the problem comes with the saving all the data ( the text for the recipe and the path of the pictures ) cant put it in a string because in that case the user cant puts his own recipes and pictures...
thanks in advance

Since you are using MFC, check out CFile, CArchive, and serialization.
From a design perspective, don't focus on your project as a whole. Instead, work on the small pieces first (e.g., reading from and writing to a file, populating a listbox, filtering a listbox based on the contents of an edit control), and they will eventually meld themselves into a working application.

Hi, all!

What have you done so far? Did you succeed in using some OpenSSL example code? Maybe you can describe your problem more specific then it's easier to help.
