View 5 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

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).

I have a group of 25 labels named Label1, Label2, Label3, ... Label25 in a square of 5 per row, 5 per column and I wanted to assign the backcolor to all of them on a loop and assign a value of "True" or "False" to a matrix of 25 boolean values representing them.
But I was getting errors on the pattern created.
My approach was to use a substring containing a number copied from the label names:
Num = Val(sender.name.substring(5))
And the subindexes of the matrix:
p = (Num - 1) / 5
q = (Num - 1) Mod 5
The values for the lower corner of the matrix were rouded to 5 instead of being 4. Instead of (4,0) ,(4,1), (4,2), (4,3) (4,4) I was getting (5,0),(5,1)...(5,5)
So I solved the problem by creating two single variables "A" and "B", doing the divission and MOD operations on them, finding the floor of them and then converting to integer:
Private Sub Label1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles _
Label1.Click, Label2.Click, Label3.Click, Label4.Click, Label5.Click, _

I'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%.

How do you convert a decimal into a percentage in visual basic? I have the code to get the problem but I need to move the decimal over two places.
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 need a function that takes a decimal, with a certain number of digits behiond the comma and convert it to a string with a different number of n digits behind the comma. (to display it)My problem is the rounding ip/down.
like 123,789 with n = 2 --> 123,79
or 123,4 with n = 0 --> 123
or 123,5 with n = 0 --> 124
I did not find an existing function that does that, so I wrote one myself.However the code has become soo complex and it still does not work well, and I get frustrated to spend soo much time with something so trivial.Does anyone know a function that can do this? There must be something out there.
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%.
What is the rounding method that VB.NET uses when a double is used in a for statement like this. It looks like 5.5 is rounded to 6 and 10.5 is rounded to 10. The output of the program is 6 7 8 9 10
Sub Main()
Dim A As Double
