I have a background process that require about 1 min to come to completion.
All the data are in memory and it does not need to read the harddisk.
I have noticed that the CPU utilisation during the full minute is less than 20%
is there a way to force the application to use more cpu to reduce the calculation time?
My new office project is based on an MVP design and is in VB.NET (.NET 3.5), using multiple libraries (like EntLib, internal corporate framework, etc.). The number of DLLs used as references is so huge (almost 50) that when I try to build/debug the application in VS2008, it takes almost 3-4 minutes to get the website running successfully.
Wanted to know if there are any settings/areas which upon some modifications can help me reduce the build time? and what exactly can be the major reasons behind this long loading duration?
I've a very simple situation, which of course I can overcome with logic, but is there a built in VB function to ensure the following:
Dim price
Dim subsidy
if price - subsidy <= 0 then
price = 0
end if
In practical terms, I've lots of other things going on to calculate price, so I want to simplify this to:
Dim price = calculatedPrice - subsidy
and wrap that into some VB formating that ensures if price ever becomes negative it's forced to zero.
I'm thinking that a simple "Type" conversion might do it, but am not sure which type would suit.
The idea with this form is to add the futures which is calculated when the button is pushed but I need the list to update every time and show the values each time to which the previous value is added to the new calculation, e.g. of what it should look like in listbox:
Year 1: $1,290.93
Year 2: $2,724.32
Year 3: $4,350.76
etc....
I have been working on this a while and I am at a standstill, I was given a function to clear the form everytime it calculates but I don't know how to implement it, I am new to VB. Here is what I have so far:
Public Class frmFutureValue
Private Sub btnCalculate_Click(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles btnCalculate.Click

i need to reduce an amount of time by x% this is what i have so far [code] as u can see ive taken the hours minutes seconds from the time and stored each in a seperate variable so from 02:30:00 i then divided the hours by 60 and then 60 again to give me the total seconds in the hours and then divided the minutes by 60. i then added all 3 to give the total amount of seconds so now the buildtimetotal variable now holds the total in seconds i now need to reducce this by x% all vars are dimentioned as integers except for buildtimehoursback which is a double the problem seems to be when i try to convert the total seconds back to hours minutes seconds.
View 3 RepliesWith a Time value in my program. Basically, I am importing a travel Time from a database e.g. 3:45 so it takes 3 hrs and 45 minutes to get from a to b. I then want to double this - 3:45 * 2 = 7:30, and then want to multiply it by a cost e.g. travel is charged at 25 per hour. so it would be total travel time = 7:30. Travel cost = 25. Total Travel Cost = 7:30 * 25. In the access db, it is stored as a text field, and then imported in vb as a string.

View 1 RepliesI have a system in VB.Net 2003, and that system takes a very long time to load. From the minute I click on the EXE, it takes one minute before the log in screen appear (P4 with 1GB RAM, no other application running). The size of the EXE is 33.2MB. I think the problem is the way I code the program, 1) I declare all the form as obj when I first load the system and I've got over a hundred forms. I try to load them as I need them but it does not work cause forms with sub form would give me an error. 2) I am using dataset as we know dataset is not very efficient but I don't know how else to connect to the database. Is there anything like ADODB in VB6?

I am working on VB.net 2008 and sqlserver 2005. I have use very much of shared object so second time it memory allocation is less, but how i can reduce it when form is close or not in use. can i use Garbage collector or Dispose and how i use this functionality ?
I have a DataGridView which I AllowUserToAddRows behavior enabled. I want to be able to force that only one row be added at time, then if the user clicks the save button the row is inserted into the database, and then another row may be added if the insert was successful.
The reason I want to do this is to get the last inserted id and insert that information into another table.
I wud like to calculate the time difference between two values.I have two values which is the in time and out time of each employee.Subtracting in time from out time should yield the time the employee has stayed at the office If the in time is 09:00:00 and the out time is 18:00:00.The difference between the two would be 9 hours.

I need to be able to display 60 * x. X is going to be the time between hitting a Stat button and a Stop button in seconds. I need this to be shown until it is stopped. So i was thinking something like txtBox1.text = 60*time, but I do not know if that is correct and I do not know how to get that time. Also I am not sure how to continuously update the text box.

I've read numerous posts and threads about random number generation, but I havent' run across this.If I generate a bunch of random numbers, the results are radically different if I create a new Random generator for each number than if I use on Random generator for all the numbers. The results are much more consistent and evenly distributed if I use the same Random generator.I would have thought the opposite,because creating a new Random generator each time should reduce the number of random repetitions, if a different time slice is used to create the random number.[code]......
View 9 RepliesToday I discovered that something I had assumed about VB.NET for many years was not true (worrying!). I assumed that a variable declared within a loop had a lifetime of the iteration it was declared in, but in fact it seems it has a lifetime of the whole procedure.[code]I had assumed an output of False, True, False, True but instead it is actually False, True, True, True..In C# the equivalent code would not compile as you would get a compile time error of Error "Use of unassigned local variable 'var1'".I realise there are many ways to fix this and that best practice would be to declare the variable outside of the loop and reset it at the beginning of every loop through.I find this behaviour so counter-intuitive to me that I would like at least a compile time warning in VB.NET when/if I do this. (I could also then set this on any projects I already have and get warning that would allow me to check that my assumptions aren't causing errors).Does anyone know how/if I can get this to generate a compile time warning in VB.NET? Am I the only one that finds this counter-intuitive?

View 1 RepliesI have written an application for a customer, and the application is run in various locations around the world. The company carefully controls the release of the software to the various buildings where it is being used, and because of this, I have made use of the "Check for updates" feature. The problem I am faced with, is that the folks using this software more often than not answers "NO" when prompted to download and install the latest version of the application. This is unacceptable and ultimately, we'll need to go in and have them manually install the software.
We don't publish updates to the software w/o meaning for them to be necessary, and I find it hard to believe that Microsoft doesn't recognize this sort of thing as being needed when they designed the update procedures. Alas, this seems to be the case.
Is it possible to use the strategy to force an application to update completely every s often to prevent piracy.I mean somenone manage to crack our click once application and make some modification.but inside the application there is some part of the code that make mandatory to update it.in each update all the application is replaced completely in this way the application on the user computer is a clean one and not the cracked one so the checks for seraching for serials numbers are reinstaed is it possibile to use this as technique to prevent piracy?
