I don't think C# is sharp enough to cut paper.
If your printer can cut paper, there must be some command to make it do so. I would try sending an ASCII formfeed; then read the documentation.

Hi.
I just bought a Vaio VGN-AR890U Laptop.
It's OK. but there is a problem !
It has 4GB Ram , But its default OS is Vista 32bit that doesn't support 4GB Ram. To use 4GB Ram we have to install Vista 64bit.
So I'm looking for Windows Vista 64bit drivers for VGN-AR890U.
The official support web site ,is for American Laptops
http://esupport.sony.com/US/perl/model-home.pl?mdl=VGN-AR890U®ion_id=1[^]
My laptop made in China, So I can't use them 
Could you guide me how I can install a Windows Vista 64 bit ?
Many thanks in advance

PLEASE LET ME KNOW IF ANYONE OUT THERE HAS AN APPLICATION TO CONTROL 4 OR MORE SERVO'S FROM A PARALLEL PORT. I AM LOOKING FOR SOMETHING LIKE THIS APP, WHERE A JOYSTICK COULD BE USED, BUT OPTIONAL : http://www.hvlabs.com/serservo.html[^]
Please let me know A.S.A.P. if anyone has any app , like this, http://users.swing.be/philippe.jadin/servoen.htm[^]  because this file is corrupt, it pops up about 30 times with a window saying Privilaged Instruction.

I voted you down because writing ALL CAPS OVER EXTENDED PERIODS OF TIME is considered "shouting" on the net.
Cheers,

The file is not corrupt. Although I am not a Delphi/Pascal software engineer... I downloaded the source code at the URL you provided and viewed the source code. The instructions which are privileged are located in this function:
procedure outvalue(value : smallint);
begin
asm
mov dx,0378h
mov ax,value
out dx,al
mov dx,037ah
mov al,00000001b
out dx,al
mov dx,037ah
mov al,00000000b
out dx,al
end;
end;
The assembly instructions are performing raw port I/O which are indeed privileged. You can probably get this software to work by giving it permission to read/write raw I/O ports in protected mode. I would suggest using PortTalk - A Windows NT I/O Port Device Driver[^] to give this application the correct permission mask.
Best Wishes,
-David Delaune

Good day
Thanks for your post.
I have found an easier way to fix this app.
If you right click the application file, then go to properties, then click on the compatibility tab, click on the Run this program in compatibility mode tickbox, then select Windows 98 / Windows Me and click ok.This fixes the app to be used in XP.
If anyone knows of an better app to control more than 4 servos, directly connected(No hardware eg. servo motor controlers or any other electronic components)to the 8 data lines of the Parallel port please let me know.
Thanks again.

Good day.
I have tested the app (Servo Commander in my original link),and noting is happening, i have connected the servo to a 5vdc power source, and the data cable of the servo to the data pin on the parallel port, but nothing happens if i move the sliders, can anyone help me please??
I am still new to programming, and do not quite know what i am doing.
can someone please see what the problem with the app might be, and may it work if i anstall windows 95 rather than my current XP Pro.
Please guys i need help, please reply.

I gave you the correct answer in my original post. You cannot perform raw i/o under windows XP.
ROVIO wrote: can someone please see what the problem with the app might be, and may it work if i anstall windows 95 rather than my current XP Pro.
The application is performing raw i/o and failing because XP is executing under protected mode[^] and those instructions are privileged. The assembly code in the software is essentially performing the same functions as _outp, _outpw, _outpd[^] and as the MSDN states:
Because these functions write directly to an I/O port, they cannot be used in user code in Windows NT, Windows 2000, Windows XP, and Windows Server 2003
You have three choices:
1.) Give your application the correct i/o permission mask using PortTalk - A Windows NT I/O Port Device Driver[^] or another similar technique.
2.) Execute the application under Windows-95 or Windows-98
3.) Write a device driver to perform the i/o.
Best Wishes,

Good day Dave
Thank you for your post.
I think i will go for option 2 on your list.
You guys are realy good at this stuff. 
Thank you for your quick responce.

Good day
Thank you for all your help so far, I never even knew that you can not write directly to a parallel port in XP, i thought the app (servo cammander is faulty.
I found an easier app to give me access to the LPT1 port http://www.embeddedtronics.com/design&ideas.html[^] (userport.zip file [USERPORT])I will install it tonight & test it, but i am sure it will work fine.
Looks like my robotic tank might be up & running in no-time.
1. Does anybody know of an app that control more than 4 servo motors directly from the parallel (LPT) port, because in(Servo Commander)like this http://users.swing.be/philippe.jadin/servoen.htm[^] there is only 4 displays & 4 data line sliders.
2. Can anyone edit the source file to support all eight ports and with all eight sliders?
I do not know how to get the source files to an .exe file, so if someone is daring enough and can do this, please send me the completed.exe file & not the code.
Thank you guys, and i do hope someone can acheive this task.
Have a great day

Or use dedicated hardware for the motor controller instead of risking the parallel port because the motors drew too much power and blew out the I/O chip.
That way, you won't have to be doing any privileged I/O (which can only be done in a device driver!), and the SDK that comes with the hardware will make it MUCH easier to control the motors.
A really good example of such can be found here[^].

Good day Dave.
I am already thinking of using the PhidgetMotorControl HC for my robotic tank, but it works out too expensive to buy a seperate controller just to control 4 to 5 servos.
I think the best bet will be to install windows 98SE on my robotic tank. I do a remote login to control my robotic tank, annd do not like Tight/real or any other VNC app.
1.Is there a way to install the Microsoft Remote Desktop app in Windows 98 Second edition?
2.& will all my apps (eg creative webcam NX software & other camera,wireless card,3g Modem software)work in win98 if they work in XP Pro?
Thank you very much for your post.

No. RDC Is an XP or later only feature. There're a number of VNC implementations, you can probably find one that will still work in 9x if you look.

Debatable. 9x support is being dropped in a number of apps and drivers.

Nope, not supported on 9x. You'll have to find a third party solution for that.

Yes, IF AND ONLY IF you canstill find drivers and software that still works on 9x. Since the entire 9x line of Windows was retired, a long time ago, driver and software support has all bust disappeared.
No, the XP drivers will NOT work, nor should they even install, on Windows 9x.

Good day
I installed Windows 98SE last night, and i can not believe i paid for that crap back in the day.
Well at least the app (servo commander) worked like a dream.
You were right, almost no XP apps worked in Windows 98SE, so that means, revert back to XP and try to get direct RAW I/O access to the LPT1 port so the app (servo commander)will work in XP.
David Delaune suggested using PortTalk - A Windows NT I/O Port Device Driver[^] to do this, but i had a look, and it seems very complicated.
Please let me know if anyone knows an easier way to get direct RAW I/O access to the LPT1 port.
Thanks to all you geniuses out there for helping out

It does not get much easier than this:
1.) Download PortTalk[^]
2.) Download Servo Command[^]
3.) Copy the Servo.exe executable into the PortTalk folder.
4.) Right click in the PortTalk folder and create a new shortcut which executes 'allowio Servo.exe /a'
5.) Double-click the newly created shortcut.
In under 30 seconds you could be experimenting with your servo motors. It doesnt get much easier than that.
Note that you will need to execute allowio from an administrative account.

Good day David
Thank you, if the other app fails i will use your method.
I had no clue it is that easy.
Can you perhaps edit Servo commander so that it can control 8 servos, and not just 4 with a mouse or joystick, the topic says control 8 servos, but in the app i can only see 4 sliders?
Thanks.

Good day
Thanks David Delaune, your method worked perfectly.
All i need now is to be able to control 8 servo's with this app, The heading on this page reads "How to control 8 servo motors with a PC ?" http://users.swing.be/philippe.jadin/servoen.htm[^], but i only see four sliders, am i missing something, or is it possible to edit the app to be able to have 8 sliders controlling 8 servo's?
If anyone know what they imply, or if you can edit the app to have this functionality, please let me know.If anyone is good with programming, please have a look at the source code provided in the link, and see if you can get the app to work with 8 sliders.
Thank you guys, i would still be stuck in the stone age if it was not for the great help you guys give.
Have a great day
