VB 2010 - ScreenSaver With A Password To Protect Computer
Nov 18, 2011OK, so, I made a program that locks the computer with a password, to help you protect data from other people. It's quite simple, you open the program, it shows up in full screen, "To access this computer please type in the password"....etc.
BUT, I want it to have a "Guard". To make it act like a screen saver does. That's my plan: So, you typed in the password, and close the program. And then, if you didn't move your mouse, or press a key, or you're not watching a movie, for more than 6 minutes, I want it to automatically launch the program. Until now, I've just put in Form2.Show in the Form1's (which is the password-protect program) FormClosing class. I also made the Form2 on Full Screen, and it's opacity to 0%. That's where you will move your mouse. I made all the code until now, but I need code for making it act like a screen saver.
WIndows 7 Desktop Refresh And Picture Screensaver?
Nov 9, 2011I am using VB.net in VS2008.I wrote a screensaver that cycles through pictures. When the screensaver exits it sets the desktop background to the last picture loaded using API call SystemParametersInfo(SPI_SETDESKWALLPAPER, 0, sFilePath, SPIF_UPDATEINIFILE Or SPIF_SENDWININICHANGE).The desktop wallpaper refreshes for WinXP and Vista but not Win7.In Win7, if I run the screensaver as an EXE then the desktop background changes when the program ends. If I run it as a screensaver I need click on the desktop and press F5 before the desktop shows the new desktop background (or click and drag with the mouse to show pieces of the new desktop background).I have tried to add delays and even force a refresh by using SHChangeNotify(SHCNE_ASSOCCHANGED, SHCNF_IDLIST, Nothing, Nothing) but with no success.

By the way, I already tried to edit the power settings of the PC so it will never sleep/ hybernate, etc. But unfortunately, it keeps on sleeping after few hours.

Jun 12, 2010I have a desktop computer with a cable connection on the back that allows me to watch TV on the computer using Windows Media Center. I had the idea of writing a program that would access this feed and send it to another computer (laptop) via my network. That way I would be able to watch TV from anywhere that my network spans. I have no idea if this is possible or how I would even do it,
So I have three questions.
1: Is it possible?
2: How would I go about access the feed?
3: How would I send it over the network?
My original thought was doing it in Flash, but I'm not very good at Flash so I wanted to do it in VB.Net.

Jul 9, 2010I have a program that reads data from a scanner via the serial port.This program works fine on Windows XP.We have a terminal server set up running Windows Server 2008.I run HyperTerminal on our test terminal, it connects and reads the scanner data fine through COM1.I run my app on that same test terminal and get nothing when I scan.My app connects to COM1 without errors and disconnects without errors.BUT, the DataRecieved event is NEVER getting fired.Neither is the ErrorReceived event.I have played with the Handshaking, with the RecievedBytesThreshhold and pretty much every setup setting I found.Set it up exactly like the settings on Hyperterminal.I have even tried starting a timer on a different thread to call ReadByte every second to try to KICK this thing into doing SOMETHING.Nothing has worked.
I have been trying to fix this for an entire day now.Added events to my class trying to see EVERYTHING that is going on. All I know is, it connects to the port and it disconnects from the port correctly but nothing happens in between.No data when I scan.No event fired at all between connecting to and disconnecting from the port.I have also downloaded other's simple serial communications applications.Nothing in .NET works.[code]
Tell When Remote Computer Is A Windows Computer?
May 3, 2010We have an VB.NET VS 2005 application that goes out and connects to remote computers on the network to gather information about the running services, processes, etc.
However, not all of the computers and servers are Windows boxes, and this is causing us some grief.
Is there a way in VB .NET to determine if a computer is running a Windows OS before trying to make a connection to it?

Interactive Screensaver Access Printer?
Oct 12, 2009I am sure the screensaver wasn't meant to be used in this manner, but I have created an interactive screensaver for the company I work for which acts as a checkout station for calibrated measurement equipment.Part of this process is printing out a sticker using an SII SLP Label printer which is attached to the computer with the checkout station. Printing with the printer works just fine over the network from another computer (not running the program as a screensaver), but for some reason I am getting a -16 error (I believe that is "Unknown Error") when the program as a screensaver uses the local SLP printer. The only possible reason I can think for this happening is that screensavers aren't allowed to access printers. Is there some way to give the screensaver permission to use the printer? Currently the screensaver is able to access files on the network file share (such as the equipment database) just fine. If I were to create a TCP/IP server that acts as a proxy or go-between for the printer so that all the screensaver does is connect to localhost and tells the server to print would that work?
