Trying 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]
Searching 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..
I'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?
I'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.
We were given this and for some reason I can't get this to work right. Here is the whole thing:The following code should display three rows of percent signs in the msgLabel. The first row should contain one percent sign, the second row should contain two percent signs, and the third row should contain three percent signs. However, the code is not working correctly.
I am trying to have a visual indicator of battery life from data I receive over the networkMy issue right now is trying to find a way to have a progress bar that is smooth and looks like a battery. Additional to this, I want this to stand vertically.
I 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.
How can I receive data about the battery status for windows phone ? I checked on microsoft's site but i couldn't find anything except the charging mode :S
Im 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
I'm making a Library type app which needs to scan the whole computer when it is run for the first time. Not again ever. How can I accomplish it?I'll be using SQL database to store data. So, I can easily make a table there and store a flag and check it on first run, but is there any other way? Any native support for this in VB.NET?
i have used vb to create some simple forms but my latest project has got me beat. The company i work for has just upgraded to Terminal Server 2008 and some of our old programs need administrators rights to open but i do not want to give all 200 users the administrators password, So i wanted to know is there anyway i can create a exe with vb.net that will run a .lnk file (located on all users desktops) as administrator.
IM not looking for clink once. Do to its not customizable. What im looking for is something like App Life but that allows custom forms to be used. Or even a tutorial on how to run an update the program. Such as a patch if you will. Does any one know a free program that allows this?
I have two "Game of Life" programs. One uses a list of points that represent the live cells, and the other uses a fixed-size grid. The one using the list of points can zoom in and out, is much more elegant in coding, and has an unlimited size grid. However, it needs to search for points in the list, and the more points in the list, the more time it takes
What events are hit before form_load in a winforms app? Somewhere before the form_load a file called .ini is created and I can't figure out where it's being created. It's just .ini with no name before the extension.
Currently, 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 & "%")>
I'm in the middle of porting a VB6 product to VB .NET and .NET Framework 3.5, using Visual Studio 2008. Backward compatibility with customer VB6 legacy code is a requirement.Our VB6 product uses the COM ADODB.Recordset objects extensively both internally and in our API. They port directly to VB.NET if I add an adodb interop reference to my VS 2008 project. My question is how long will Microsoft continue to support ADODB.Recordsets in their languages and operating systems? 2018?I'm trying to make a design decision. Since backward compatibility with VB6 is a requirement, I would prefer to leave them in the .NET code. However, if support will be dropped soon in the near future, then I will use ADO.NET datasets instead, and convert between ADODB.Recordsets and datasets until support is dropped.
I've googled and binged my browser to an inch of it's life, but i'm still no nearer to an answer for this, so I'd be grateful for some advice. Mainly with the syntax, but knowing me the whole concept is wrong!I have a textbox. When user enters a string and presses enter, I want the following to happen.
I'm struggling with 3 and 4 and 7
1. Check the string is not more than 13 characters, if so trim the last characters off to make 13
2. Find if the first character of the string is a digit or a letter
We have a serial port which is connected to hundreds of physical devices on the same wire. We have protocols like Modbus and Hart to handle the request and response between the application and devices. The question is related to managing the reference count of the channel. When no device is using the channel, the channel should be closed.
I have been given some instructions to percent encode a URL twice. I know how to percent encode a URL once but how do you do it twice? Surly when it is encoded once, it will be the same when encoded again.
I am trying to filter fields in a table that contain percent (%) and apostrophe (') characters. I kow that to filter an apostrophe you need to add another apostrophe (''). However, when a text contains the percent (%) character in combination with an apostrophe (') character, an exception is thrown. Also, when using the % character in a filter string, it will be function as an "*" (fields starting or ending with). I need the % to be considered as a character whenever the % makes part of a string in the field.
Dim TheTable As New DataTable Dim col As New DataColumn("Col1") TheTable.Columns.Add(col) Dim TheRow As DataRow = TheTable.NewRow
I need help getting a progress bar to show percent in it. I want to have the percent in the middle of the progress bar, like is sometimes seen in a few programs. I have googled this, and can't find anything. I found something on The CodeProject, but it was just a label and drawing a rectangle behind it. I would like the actual progress bar that is available through the toolbox.
Is possible get the percent of a word in the content of a richtexbox? if yes, can you give me some example?
For example if I have 100 words in a richtextbox and I want to know what is the percent of a word in this content (for example if a word called "music" is repeated 10 times = 10%. If this is not possible in a richtextbox, is possible in other box like textbox?
