VS 2008 Prevent A Computer From Entering Sleep/Standby/Hibernate While Program Is Running?

Apr 4, 2011

Title pretty much says it all. Does anyone know a way to to prevent a computer from entering a low/non-processing mode while the program is running? I don't care about monitor modes, screen-savers, hard-drive spindown, etc (in fact, I'd prefer to leave those alone; I like it that it shuts the monitor off after a time period).Basically, I have an industrial program that needs to continually monitor a PCI card it uses for IO; and this activity alone isn't enough to convince Windows not to go into Sleep mode. We normally just shut the power-save features off, but we had an incident where a technician forgot, a customer's machine went to Sleep after the end of the shift, the pumps stopped recirculating, yadda-yadda big mess.

How To Prevent Program Being Started Twice

Apr 8, 2010

I have a small problem with my application. When the system starts up, the program starts with it, but runs hidden (registry key with paremeter). The program also has a GUI.I want it so that when the user clicks the desktop icon, it does not start a second instance of the executable, but instead reveals the currently running background process. Is that possible?i.e. when the application is started with the "-startup" paremeter, it loads a hidden form2, and closes form1. When the desktop icon is clicked, it loads form1, while form2 remains hidden.

VS 2010 Program Crashes As Published Executable, Not As Program Running In Studio Or Express?

Jun 6, 2012

I wrote this VB program to be able to throw a device we developed into programming mode where we use an ATMEL Flip installer to upload new firmware. I can program one device after another running the application off of Visual Studio Express 2010 or Visual Studio 2010, but when I go to publish this file and run it on another machine, it becomes unstable and crashes after each upload. On those same computers if I run the raw unpackaged program under Visual Studio Express, the system does not crash, and I can program devices repeatedly.

VS 2010 How To Prevent Fields Being Reset In Form1 & Form2 On Program Close

Nov 18, 2011

I am Matthew and I'm extremely new to coding and any sort of scripting language; yet I am highly interested in programming and want to learn lots about this subject. So to start myself off I am trying to create some applications which I could use in day-to-day life to just basically make life easier.So the first program I am trying to make I am already confused and not sure what the heck I have to do in order to get it functioning, I've looked on lots of videos on you tube for tutorials and they have all done a great job but some videos just don't answer my questions.When I click a button and "Form2.Show()" appears, how can I make it so that when I type text in a list box in form2, it doesn't disappear when I close it? Then once I have known done that, how can I make it so I can choose a random string of text in the list box on form2 to show up on the click of a button on form1? Then a final question is, How do I prevent fields being reset in form1 & form2 on program close? Also, is it ok for me to make a thread asking 1 simple question? or do I have to ask a handful each time to save threads or something?

Running One Program From Another?

Sep 11, 2009

I am writing a program (that i have recieved a lot of help with) that creates input files for another program. The bridge between the two programs is a program that has been named the task manager as like the windows task manager it shows what tasks are being done/have been done/are about to be done (or executed)

What i would like to know is how can i run the already installed bridge program from my program? Do i need to run it by opening the executable that contains it? Or by declaring the bridge program as a type/structure/class and going from there to open it?If you're not living on the edge, you're taking up too much room
