Feb 10, 2012I come back to the MSDN to ask another question now. That is:
How do you check if a battery exists in a computer?
I have the code here to figure out battery percentage.[URl]..But if a battery is not inserted it will show battery 100% and charging instead of it showing that a battery does not exist.

Aug 14, 2009Im trying to monitor the battery of notebooks to diagnose whether there charging/discharging correctly or not for my work. I can get the basic info using SystemInformation.PowerStatus but i want to be able to see the slope or decline of the charging via a graph. Is this possible? i was playing with the system monitor control and thats the kind of output im trying to get. A simple line graph would be perfect....passmarks battery test is a example of what im going for

Mar 16, 2010Trying to find a code to display ' BatteryLifePercent' by itself on the screen of a gps unit running Windows CE Core 5.0. I have absolutely no experience in programming. Just piecing together things I find and slowly learning to make a working program. So if this is possible, could someone post a code for it? Ideally I'd want just the percentage showing on the main page with ability to size font and position somewhere on the screen. [Code]

Jan 28, 2011Searching about kernel32.dll and battery functions in it, I came across some interesting
Public BatteryLifeTime As System.UInt32
The full declaration is:
Private Declare Auto Function GetSystemPowerStatus Lib "kernel32.dll" ( _
ByRef lpSystemPowerStatus As SYSTEM_POWER_STATUS) _
As Integer
Private Structure SYSTEM_POWER_STATUS
Public BatteryLifeTime As System.UInt32
What I don't understand is, what measurement do the "BatteryLifeTime As System.UInt32" is in? I mean, is the Battery life Time in seconds or hours.. Or something else, so how can I convert it to something I can use..
Create A New Battery From Scratch While Using The Old Code As A Reference Point?
May 13, 2012I'm currently starting a new job in which I will be working on some coding in the future and need some advice on some good places to start so I can learn this correctly. Essentially we need to bring VB4 code over to the new VB.net language and I will be tasked with this. The project consists of a large battery of tests for psychiatric patients consisting of mostly multiple choice questions presented one at a time - since VB4 isn't very compatible, I think I will create a new battery from scratch while using the old code as a reference point.
I started creating the code this weekend for fun and am really enjoying it. However, a huge problem has been the abandonment of control arrays in the new language... by the time I got to creating my first questionnaire I'm stumped and can't follow the old code. Clearly I'm not ready to tackle such a large project with no experience and need to start from scratch; who would have thought .
The reason why I'm here is not to ask you to help me with my work. What I'm wondering is if any of you have any cool advice of great places to start learning the language (books, websites, etc). The amount of literature is very overwhelming so I thought I would ask some people with experience for tips. If any of you have stumbled across learning material with emphasis on coding that would be useful in the design of questionnaires or multiple choice exams, it would be particularly useful.
So far my starting place is Visual Basic 2010 Step by Step with Michael Halvorson, it seems good at a glance in the sense that it couples theory with practice but I'm already sure I'll need a little more.

View 4 RepliesVS 2005 Saving Battery Level Variable To Text File?
Jul 28, 2010Currently, I've encountered a problem where I do not how I can store the variable of my battery level in a text file. I tried .xml and .txt file and it returns me text which can't be read.The code related:
vb.net
[code]Dim psBattery As PowerStatus = SystemInformation.PowerStatus
Dim perFull As Single = psBattery.BatteryLifePercent
[code]....
The place where I do not know what to insert is the "Insert Battery Percentage Here" part so I guess that's the problem.For your info, if you were to use a MsgBox to display, the code which displays that would be <MsgBox("Total battery power remaining: " & perFull * 100 & "%")>
VS 2010 : Make A Little App That Displays The Battery Life Of A Notebook - Timer Not Refreshing?
Nov 19, 2011I'm trying to make a little app that displays the battery life of a notebook, and also whether it is charging or not.I've got it displaying the battery percentage and if it is running via the cable or battery alone.My problem is that I have a timer constantly ticking to grab the latest information as to whether it is still chraging, what the battery % is like, however for some reason when it first runs it get's the info but then that's it, it won't refresh the info in real time. I'm confused because the battery can deplete but the program only displays what info it got when it was first ran but if I unplug the power cord or plug it back in it refreshes that info straight away. My code is:
Public Class Form1
Dim psBattery As PowerStatus = SystemInformation.PowerStatus
Dim perFull As Single = psBattery.BatteryLifePercent
Dim GraphicPercent As VariantType
[code]....
The bit I've highlighted in red in my code won't work either, basically I've shaped the two labels to look like a crude battery shape and label2's function is to represent the nobly bit at the top of the battery and I wan't that to change to Lime when the battery is 100%.why it won't refresh the graphical output to the screen?
VS 2005 Windows Services - Process Is Listed As A SYSTEM Process Rather Than A Process Under User Name
Jun 4, 2009I have written a windows service that is meant to launch a notepad when a specific action happens. The problem i have is that even though the service launches notepad, the actual notepad it self is NOT visible. I know that it has been launced because i can see the process in the task manager. By the way the process is listed as a SYSTEM process rather than a process under my user name (i believe that is because my process is a "LocalSystem" one).

Process.start() Freezes Main Program Until Process Finishes?
Feb 21, 2011I have a program that starts another program after setting the regkeys basically the program continually syncs the calandar of outlook and another application.I set the regkeys than launch the c:sync.exe app. I have tried a simple process.start and launching the process as a thread and they both do the same thing: The other process starts and works as it should but my main program goes "White screen" or "not responding" until the process.start has exited.
I want the process.start to run in the background so if users click in my main app it responds and truly that they can access the context menu of my main app from the taskbar while the process.start is running.

View 9 RepliesVS 2010 Launching New Process & Detecting If That Process Has An Error Message
Nov 19, 2011I am working on a small VB application that listens for commands sent from an Android app.
One of the functions is to extract an archive. I am familiar with how to listen for the unrar process to finish, so I can display a progressdialog on the phone while the extraction is happening, and clear it as soon as it's done.
BUT ... if there is an error/alert from WinRAR, WaitForExit() never gets called because WinRAR is still sitting there open until I click "OK" on the MsgBox.
For Example ... if you try to extract a file that is not actually an archive... an alert will pop up saying "No Archives Found", and basically everything is halted on the VB app and the Android app, and the Android app just sits on a progressdialog saying "extracting..." until you manually hit "OK" on the computer.
As you can imagine, this is a problem if the whole point of your app is to NOT have to go over to the computer.
So... I am wondering if there is something similar to WaitForExit() that will wait for an error and allow me to close out the alert and let the process end.
Here's my Sub for the UnRar command:
Private Sub UnRar(ByVal WorkingDirectory As String, ByVal filepath As String)
Dim objRegKey As RegistryKey
objRegKey = Registry.ClassesRoot.OpenSubKey("WinRARShellOpenCommand")

[2005] Using Process.MainWindowTitle,Process.MainWindowHandle On Some Older VB6 Applications
Feb 10, 2009I have an issue using Process.MainWindowTitle,Process.MainWindowHandle on some older VB6 applications. After Process.Start I use Process.MainWindowTitle to display in a listbox. The MainWindowTitle returned is not the Window Title but in fact the Project name of the VB6 exe.? I also store the MainWindowHandle to use the ShowWindow and SetForeGroundWindow API's. It would appear that the ShowWindow API does not work, but the SetForegroundWindow does. ie: if the VB6 app is minimized, showwindow does not restore, if it is NOT minimized setforewgroundwindow sets it to the foreground. The exact same code does work correctly for any other .net exe or notepad, only on these vb6 programs I am having a problem.

Passing Variables From Child Process To Parent Process
Feb 13, 2012I have a procedure (parent process) that starts several processes (child processes). The child processes calculate several array variables. How can I pass those arrays to the parent process? At the moment, the child processes write the arrays to a streambuilder and the parent process reads the stream. Is there a better way to do it? Is it possible to have the child processes write to RAM memory and have the parent process read from there? It is like declaring a global variable in the parent process and give the child processes access to it.

Aug 31, 2009How can i access a file through FileStream which is being used by a window service. Actually i am trying to access a file which is also being used by our window service. I need to read data from this file. I am using below code but also getting following error:
Code:
Dim fs1 As IO.FileStream = New IO.FileStream(psPath, IO.FileMode.Open, IO.FileAccess.Read, IO.FileShare.Read)
Dim sr As IO.StreamReader = New IO.StreamReader(fs1)

Error: The process cannot access the file 'FILENAME' because it is being used by another process.
I tried changing FileShare.Read parameter to FileShare.None but it didn't work out. I also read below post which says that it is not possible but i think there is a way to read it like if you open a file through Firefox but still window service is accessing it.
