Can you give more reason, why it is relate to the permission problem at the user level? For my opinion, i don't think about permission problem. I think it might be relate to the network traffic which is over the ability of the server that could not handle it.

For network connection which is disable, i usually found this problem with my brother computer. I create an account for him as in a User level, but sometime when he start the computer, the network connection is disable but the cable still attach to his computer and the hub/switch is still running. Until i restart it again then it is start to work again. Until now, I still could not find the solution that why sometime network connection is disable when we start windows.

Hi,

I am trying to develope a program for a client that allows them to view activity and the screen of several machines at once. I know that there are programs out there that allow you to do that, but the client is a teacher in a rural school district and can not afford them.

Thanks

it may be simple enough.

try this article:
http://www.codeproject.com/cs/media/directxcapture.asp

once you obtain the screen/audio data, sending them over the network is simple (or not?)

you can send some data packets (maybe screen frames compressed in jpg?).

In my opinion, i think you might need the student PC to access the teacher PC screen during the time that they take the lesson. How about sharing desktop with netmeeting?[^] Is this match what you need?

Hi,

I is a a very generic qurey (not associated with a particular software of hardware in specific)

I have and a hardware adapter with an FPGA in it. It could be connected to the PC via a USB port, with a driver for the same installed on the PC.

My query is, if I have two similar adapters which I connect to two ports. Will two drivers be required for it. Or will there be two instances of the same driver created

Could you please clarify.

Thanks,
Surbhi

Softkey Assign

I would like to assign some text to some of the function key on the keyboard.

how is this done?

Also would it be safe to say have key F9 set to "myEmail@myISP.com" and F10 set to "myPassword".

Many thanks,

If you are using VB and use the KeyCode event handler of the text, you will be able to perform an action based on the function key that you assigned.

Are they any way within the operating system that will allow you to assign text to these keys such that when you press F9 when in a textbox the following text is entered into the box "myEmail@myISP.com" etc

I don't know how to use it, but how about RegisterHotKey[^]?

Hi It is quite simple. first you sould use the RegisterHotKey API for example for F9 key. Then in your program's main window's winproc function, write code for WM_HOTKEY to get when the desired hotkeys are pressed. Then use the SetWindowsText API function to set the desired text on whatever window you like or more easily, call kybd_event API function to simulate keyboard input.
If you have question about any of these steps, let me know and I would describe.

Hope it was helpful

Thanks for the post.

Just one futher question, if I wrote a program that assigned F9 and F10 as hot keys (with some text), then I ran this program when Windows starts up would the text assigned to F9 be placed into a text field when pressed F9 is pressed in another standard WIndows application.

i.e.
if F9 = "myEmail@myISP.com"
F10 = "myPassword"

when prompted for my e-mail and password could I just press F9 then Tab to the next field and press F10?

Many thanks,

Ofcourse!
The hotkey has in fact been produced for the same reason, while you can simply get the Key_Pressed event when the focus is on your own program!!

What I was after was when the HotKey is pressed when another Windows program requires text input, then the pre-defined text would be entered into the text area; e.g. userName and password.

The other program does not know about the HotKeys.

I can see how to register and unregister HotKeys and use them in my programs, but its other Windows programs.

Maybe I am thinking of a Macro key press sequence.

The question was can some keyboard keys be assigne some text strings that will be entered into text fields which are active in another program when these keys are pressed?

Creating a blue screen

Hi, I am interested in how different companies manage to create a blue screen which halts the operation of the computer until it does what it wants to. For example Symantec, the people who create Norton antivirus, create a blue screen when you rename your hard disk; and there is another company who actually stop the booting of windows to bring up a screen where it does registry defraging.

So how would you create something like this?

Thanks,
IanG

In Win 9x, the real-time scanner navap.vxd uses a kernel-mode call to switch to text mode and show the prompt.

So to do it you would have to create a driver, is there any other way without the use of drivers?

I don't know, you'll need to consult the DDK and check out the docs.

kernel api function?

Hi.
I've made a virtual drive which contains the contents of ftp server. Because my computer may be offline frequently so I need to syncronize all the contents from ftp server to client and put filenames (and their size) locally on my virtual drive.

What I want is when I go into the virtual drive. It notifies my app that particular folder of my virtual drive is being accessed so I can dowload the filenames and size and make sparse files in particular folder.

Is there any api in kernel which gives me the required functionality?.
hope I defined enough. thanks!
