Just wondering how i could do this in vb.net?
but I found this eg in c++ showing how to do it as a wmp visual: [URL]
I created Dataentry forms. In the form there are so many controls like DropDowns and textboxes. I am using Access database. Now I enterd the few records into the controls, and these records are saved into the Database. But now if i enter the any data which i recently saved in the database to the textbox or any other control then the remaining controls should be display the related data.
For example i have 4 controls in my form one is dropdown and 3 are textboxes. If i select the data in the dropdown then the remaining 3 textboxes shows the related data. How can i dispaly the corresponding data to the other controls?

View 1 RepliesI 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?
View 1 RepliesWhen it is run, screesavers and screenoff is prevented somehow.. I have narrowed it down to this 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?

View 1 RepliesOK, 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.

View 2 RepliesI 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?
