My application uses a touch screen from ELO TouchSystems[^]. With ELO, your application doesn't know that the touchscreen is installed. The touchscreen works in parallel with or in place of a mouse. The touchscreen can perform single clicks, double clicks, and drag and drop operations. There is no way to implement right click operations using the touch screen only, unless you place a touch area (a button) that means "perform a right click on the point I was last touching", which isn't very intuitive.
The biggest modification you have to make to your application is to make windows and controls touchable. This usually means making them larger, and making their touchable areas obvious to the user. I've found that a 'metric' value of min(screen width,screen height)/12 is a good minimum size for a comfortable control.
Push buttons are easy; just make them bigger. Radio buttons and check boxes work better if they are made larger, and they are given the WS_EX_DLGMODALFRAME extended style. This gives them a raised edge look that gives the user an indication of the touchable area for the control.
Edit controls require an on-screen keyboard. I've made mine task-specific, so I use a numeric spin button, a numeric keypad, or a full alphanumeric keypad depending upon the contents of the edit control.
Scroll bars and track bars are more difficult. The sizes of the Windows scroll bar controls are fixed by the system metrics values. You can increase the size, and Windows displays the scroll bar at the larger size, but it doesn't scale the arrows well, which is ugly. The thumb control for the track bar doesn't appear to resize up to a touchable size. I ended up writing my own scroll bar and track bar controls that sized appropriately.

That's useful to know, particularly the link to ELO, who have international resellers. I like the idea of an on-screen numeric keypad, but I'm not sure I'd want to use a full alphanumeric one!
Is your keypad simulating a staggered qwerty, or is it more rectangular? Don't suppose it makes that much difference to the user, since touch-typing (in the conventional sense) isn't likely to happen!

The alphanumeric keyboard is a staggered QWERTY. The keyboard is a relatively simple dialog box, and the keys are pushbutton controls. One important note: the pushbutton controls are a little unusual. Normal pushbuttons issue a BN_CLICKED notification when the button is released. The pushbuttons I use in my keyboard and numeric keypad issue a notification when the button is pressed. This results in a much more natural feel, in terms of the onscreen keyboard feeling like a real one.

I am currently accessing the internet through a proxy server. However, I can't seem to get any IM (MSN,Yahoo, ICQ, etc.) to connect using the same proxy.
Is there anything else I'm missing?

Sorry if this is the obvious, but did you configure access to each of the programs? (They don't run off the Windows proxy settings)... Make sure you've selected the correct proxy type (Mine is HTTP) and that should be over port 80.

Yeah, I did. Didn't help though.

IE Works though or no? The only other thing I can think of is if you are running over port 80 and have IIS installed then it can't route traffic beacuse you already have something using port 80. What kind of proxy server is it? A service or just a free proxy or what?

IE works just fine.
Never mind. A friend recommended e-messenger. Less hassle all around, I think.
Anyway, thanks for the assist. ![Beer | [beer]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/beer.gif)

All of the IMs I know of use ports other than 80 for communication. You have to enable those ports on the proxy server to allow them to work. Changing the programs to use port 80 won't help because the server end of the connection isn't listening to that port.
Some people think of it as a six-pack; I consider it more of a support group.

Hello all,
I have created a certificate using the makecert.exe utility (I do not have a certificate server available at this moment). The certificate was created and I moved the certificate to my C:\Intepub\wwwroot directory.
I then opened up the directory security tab in the web site properties dialog box. Then, I clicked on the Server Certificate button and the "Welcome to The web Server Certificate Wizard" opened. I clicked next--> selected radio button option "Assign an existing certificate" and clicked next. The IIS certificate wizard opened but there was no option to browse to where my certificate was located (in: C:\Intepub\wwwroot).
How do I install the certificate I created into IIS? I have looked all over msdn and the web to find some hint of how to do this, but could not find anything.
Any and all help would be appreciated.
TYIA,
lonelobo

I had to issue the following command:
makecert -r -n "CN=www.benningfield1.com" -b 01/01/2000 -e 01/01/2036 -eku 1.3.6.1.5.5.7.3.1 -sk ANewKey -ss my -sr localMachine -sky exchange -sp "Microsoft RSA SChannel Cryptographic Provider" -sy 12
After that it the certificate wizard "saw" the newly created certificate.

You need to use Microsoft Management Console to import the certificate into "Computer" certificate storage (it's MY logical storage, Registry\HKLM "physical" storage). Then you can select the certificate from storage in IIS.

How about doing it the easy way? Download the IIS Resource kit from microsoft's website and run SelfSSL.

What is difference between server o.s. desktop o.s. and network o.s. ( operating system) Please explain in detail?
|
|
|
|
|
They really differ in use. Many operating systems come in several flavors because of this, e.g. Windows, Linux, etc.
A Desktop OS targets an end-user, and is [usually] optimized for Graphical Interfaces, Media, et al., while not needing robust features required or needed by Server OSs.
Server OSs are meant to be used by multiple users and as such are optimized for background processing, application/file sharing, print services, databases, internet and network services, fault tolerance, etc.
Network OSs are meant to be used by clients (such as a Terminal Server Client for Windows or VNC or an X-Windows client in the case of Unix.) Applications and ilk run on the Network OS across the wire, the client just sees a representation of it on their "terminal." The client is usually the only software running on the local machine when using a Network OS -- and may be a very stripped down OS whose sole purpose is to be a "terminal" to a Network OS.

I'm going to resolve my server problem by adding a new drive as C: and re-installing Win2K Server on it. I can then recover anything I need from the existing drives at my leisure, after I have a clean, stable server configured. The question is, since I'll be installing the new drive on IDE 0 as master, when I move one of the existing drives to IDE 1 (where the CD-RW currently resides alone) should it be master, or slave? If this was a simple CD-ROM drive, I'd make it a slave, but I'm concerned about problems writing CDs if the CD-RW drive is not the bus master. Any thoughts?

I don't think it would matter, I'm running my CD-RW slave to my DVD-RW and it works fine. I don't think the master/slave issue is really as pertinent as in the past which is why SATA doesn't have it.

Hello,
Is there any way to programatically restore a foreign application from the system tray? (the same as, in most cases, double clicking the tray icon)
All I have found are ways to maximize/minimize windows that are already running out of the tray...
Thanks for any help!

Hey everyone,
Well I am fairly new to linux and I have been messing around with Red Hat. I have been looking for information on the web but just cant seem to find it. I am trying to access data on my windows XP partition while I am in Linux. I see online you are able to do this with FAT32 but not NTFS. Is there anyway to access my NTFS data from within Linux without recompiling the kernal? Thanks for all of your help! 
There are 10 kinds of people in this world. Those who understand binary and those who don't.

As for the reason why this is made so difficult: specifics of VFAT and MSDOS are fairly well known to all. NTFS is less known because Microsoft is keeping this information a bit secret  .
Oh, make sure you download the correct rpm for your distro, maybe you have redhat 8 instead of 9 (link on first comment).
more distro's[^]
there's more to the picture than meets the eye...

Is there an way to change the behaviour of 'maximize' function for application windows?
In the past with small screens of 14", it made sense that maximise would make the application window expand to fill the screen. However, with wide screens, especially with the wide screen format of laptops, I would like the maximise function to expand the vertical size but keep the existing horizontal width of the application window.
Some time ago I saw this functionality on Unix systems that used large screens and have since missed it with Windows. Now that I have a wide-screen laptop, I miss it even more. Without it I am constantly resizing windows and instead of using the 'maximise' shortcut. It is easier to use to the 'maximize' shortcut.

I have a device that is that acts as Multiport Communications Port.
Windows XP does not remember the Multiport Communications Port. With Windows 2000, you will only have to go through the process of setting up the device as a Multiport Communications Port once. After that, you can take out the device and put it back in any time and it will remember to recognize the device as a Multiport Communications Port with the same settings. In Windows XP, you will have to install and setup the Multiport Communications Port every time you connect the device to the laptop. 
This also includes every time the machine boots up with the card connected.
Not only that, but Windows XP will also use a different COM port every time you install it because it thinks the previous COM port it was using is still in use.  You can manually change the COM port back to its previous value in the Multiport Communications Port Properties.
How to work around this? Anybody knows?
