Interactive Screensaver Access Printer?
Oct 12, 2009
I 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?

This program is very difficult for me, but I must get threw it or I cannot finish... What I am doing is making a Database of foreign Languages with the spelling of the words and the pronounciation inside the database... The USER enters a paragraph of words into the translator textbox and pushed translate. The program has a DATABANK of words with the phonetic spellings and matches the word, then translates to phonetics. The problem is that new words keep appearing inside the language. So I incorporated a Database of 2 fields

I'm trying to enable the screensaver from within my application I found this code on the internet:
Declare Auto Function SendMessage Lib "user32.dll" (ByVal hWnd As IntPtr, ByVal Msg As UInt32, ByVal wParam As UInt32, ByVal lParam As UInt32) As Int32
Const WM_SYSCOMMAND As UInt32 = &h212
[Code]....
But it's giving me an error "Expression expected" on the three Const lines right at the & character.

When it is run, screesavers and screenoff is prevented somehow.. I have narrowed it down to this code.
[code...]
The above code is what makes it possible for my application to active two forms when only one is activated.. But it is somehow this code that prevents my screensavers and power settings from working.. Do you have any idea how to change the code so it doesnt prevent my screensavers and power settings?

OK, 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.

I 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.

I don't have any idea if it is possible and how can I code it.I have created an application that needs to run on a non-administrator account on windows 7. It won't run if the PC goes sleep/ locked/ hybernate/ on-screensaver. So, I want to disable them programmatically using vb.net 2010. Can any one help me?
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.

Running a graphics effect in the Paint event of a Form. I am thinking of something like a screensaver effect, not necessarily full-screen either. Would a background worker be better suited to this idea or using another thread? I wouldn't want something that is very demanding on a computer processor. In fact, what I was originally thinking, is it possible to put a Windows screensaver program inside a Form?

1. Detect if my printer is busy, because my code tells the printer to print more pages that it can cope with, so I need to delay the command for 'Print the next page' until the printer has finished printing the previous one.
2. Shift the output to my printer so that it gets printed in it's entirety on the paper, instead of seemingly being anchored to some nebulous point on the A4 page. It starts printing at X = 29mm from the left edge, and Y is 28mm from the top, and stops at X = 22mm from the right edge and Y stops at 22mm from the bottom edge, leaving (aprox) 50mm of X and 50mm of Y unprinted.
3. Get useful information on Bounds, which I'm fairly certain is what I need to control where my printing should start and finish.
I've hunted through this forum, MSDN, 'Help' (a misnomer if ever there was one) the VB Library and one or two other forums, which either baffle me with reams of code or suggest code to try which either just don't work or which doesn't declare all the variables and usually don't suggest what type of variable I need, it's all very frustrating

In doing mathematics, I need to enter many values from equations into an array or arrays. I want to be able to vary these value any time I run the program.
I would like to know how to do this while the program is running?
back in the days of Quich Basic, it was simple, ie
Dim array(9)
For I = 1 to 9
INPUT array(I)
Next I
The program stopped at each pass to let you enter values.
How can you do this in Viual Basic 2010 for example

I am trying to sort my report on the values in a column. The underlying query consists of a director colum a movietitle column and a rating column, for every movie a director has directed there is a record which off course shows the rating in the ratingcolumn In my report I have grouped by Director and created two other columns which are called: Nr of Films and averageRating. in the design view i used two functions to accomplish this. the first is: count('the field of the rating') and sum('the field of the rating')/count('the field of the rating'). This is working... but now I would like to sort the column, Nr of Films. I think I have to do this with interactive sort of the textbox which holds the column name(i.e. Nr of Films)
