View 6 RepliesI am trying to get a percentage that just does not seem to work.I am using WMI to get the Total Physical memory of my system and then the Free Physical Memory. Then get the percentage.
2147483648 - Total Memory
838028 - Free memory
According to Task Manager my physical memory is 59%. This is the code I am using but I can not get 59% or 41% that is free.
temp = FM/TM
temp = temp * 100
percent = FM * temp
Im trying to get a sales percentage program to work and im having trouble on the last part. My homework is to get the original price from the customer and then take the sales percentage off and show how much it is. Then after the first percentage is off take an additional percentage off part and then show the grand total. I got all the way up to the additional percentage off part to work right.

History:I have built my application in Visual Basic 2005 Express Edition. It is a Console Application. After filling in the questionnaire the user gets given results and all this information is stored in a .txt document (Notepad). I want the data that is put in to the application to send infomation to the user's e-mail address. I have been looking around the internet and it says it could do it but it needs Outlook express.

I have a program that is calculating the cost of a certain number of plane tickets, the validation and basic calculations are fine the only problem i've got this: There is a discount text box field called "txtDiscount" where IF a user enters a number it will discount this as a percentage off the total cost of all the tickets, but I cannot get it to work [Code]
View 2 RepliesI have a fixed percentage 0.3% I need to multiply this by a number of months which varies 1 to 12
Having done this I need to add the percentage to a pre-determined number
so as an example
£300 + (0.3 * 10)
I can get the 3% (0.3 * 10)
But when I add this to the existing number (£300) it equals £303 not £309 which is what it should equal.
Can anyone advise the way of adding a percentage as appose to just another number? This also need to allow for -percentages i.e. -3%
The equation I am using is below and I appreciate there is nothing to set decTotalPercentage as an actual percentage but that's because I am stumped...
decTotalPercentage = decPercentage * intMonths
decFinalPercentage = decMoney + decTotalPercentage
I have a problem regarding an access file I attached to this post.I have a table which contains the costs(VVGK) for each month in 2008, 2009 and 2010. For each month we have planned costs(Plan) and the real costs (Ist). And what I want to realize is that in the report in the top right it automatically displays the percentage difference between the plan and real costs of the last month. And this should then be automatic every time I give new input(new month, new VVGK Ist).
View 2 RepliesI'm developing a data logging application using VB for the actual logging to a MySQL database. I'm reading a value from a device and then running an insert query every minute. This is great but if the value doesnt change all day then my records are going to all be the same. I'd like to try and calculate the percentage of change on the value and only run the insert query if the percentage of change is greater than, say 5%.

View 8 RepliesI am attempting to draw and fill a rectangle using percentages passed through the text properties of 4 textboxes. I am attempting to do this in VB 2008. For example:
textbox1, 15%, green
textbox2, 35%, blue
textbox3, 40%, red
textbox4, 10%, orange
I have data coming in to my serial port, which is just a 6 digit number.
textbox1.text = serialport1.readline()
In the textbox_text_changed sub. I need to do something with this number, but only if it has changed by more than 2%. I need the 2% as the number coming in is fluctuating a little bit so I don't want anything triggered if it's less than 2%.
I would like to have some sort of percentage on the amount of times each button has been pressede.gButton 1 is pressed 5 times, button 2 is pressed 3 times, button 3 is pressed 2 times.I would like this to create a percentage output onto the same form that is updated everytime a button is pressed on the form.

How can i round it off to just whole numbers e.g. 13%?
what I need is the following:
1)A way to add a percentage to a ProggressBar.
2)A way to send by email the text that contains a TextBox.
3)A way to call the text of a TextBox in a MessageBox.Show.
4)A way to save what is written in a TextBox, just before it is closed.
5)A way to allow only numbers in a TextBox.
I was just thinking is there a method i can use. For example if the maximum value is 200 and the current value is 97. or i have to use math to get the percentage.

I want to know how to convert a percentage rate such as 4.5% into a decimal number in your code editor in V 2008.For example, the user input is 4.5%. Is there any function available to convert is to 0.045?
View 4 RepliesIf we format a value for percent "{0:#%}" then it will become 400%, and this also applies to all the 3rd party controls I've tried. I've used custom format as a workaround for this but perhaps you guys could enlighten me on this one. If a user inputted 4 for example then did the user intended 4% or 400%? If it were me that I would expect the 4 to be 4% rather than 400%.
View 11 RepliesI'm trying to parse a formatted percentage value back from a datagridviewcell that has been set with the "P" formatter:
double percent = 0.96
cell.value = percent.tostring("p")
gives me a displayed value of 96 % which is what I want.
Now what I'm looking for is something like what is provided for the other formatting strings - NumberStyles.HexNumber, Currency etc so that I can do this
double percent= double.parse( cell.value, NumberStyles.Percent )
which would give me a percent value of .96
I have scoured the .net documentation but can't find any sort of AllowPercent style like the others - is there one?
p.s. I see there is another question here like this and tried to expand on it in that thread, but was deleted by a moderator and told to post a new question.
I'm attempting to write an app that watching for process spikes. IE: Watch every active process and log the difference between initial and max values of cpu percentage (or load) of each process. The problem is that, as far as I can tell from the MSDN, the Process class doesn't contain any property that is even remotely equal to the true load of the process. For the time being I've written the code to watch the PagedMemorySize64 property, but the values that are being spit out appear to have no relevance to load.
To be clear, I don't need the actual load percentage (though it would be handy), all I need is a property that is directly related to load to show what processes 'spike' during the execution of my program.
My code as it stands (initialProcessCheck runs first, then processCheck runs every 1.5 seconds or so until other threads doing irrelavent tasks are finished, then computeDeltas is run):
Private Sub initialProcessCheck()
'Checks the current load on all active processes and stores as initial values
For Each intPID As Integer In ActiveProcessIDs
Dim CheckProcess As Process = Process.GetProcessById(intPID)
