Induce A Variable Amount Of Lag
Sep 2, 2010I need to induce a variable amount of lag in vb.net. System should be noticeably slower. I can raise the CPU usage of the program with infinite loops and some variable creation/assignments, but how can I actually cause lag? I'd like to have an "InvokeLag" sub which will perform an action to slow down the computer, the faster the function is called the faster it lags. The function should be as mundane as possible, not modifying anything or doing anything to cause damage other than simple lag.

View 3 RepliesDetermining Which Variable Has The Largest Value While Using The Least Amount Of Code?
Jun 4, 2010Suppose I have 3 vars:
dim a as integer = 5
dim b as integer = 1

What is the most efficient method of determining which variable has the largest value while using the least amount of code? I know this can be done with if statements, but there must be a more elegant way to do it.
Multi Timer - Set Up A Variable Amount Of Timers?
May 21, 2011I'm trying to work out a program where you can set up a variable amount of timers (like egg timers). Each timer works independently of the other (you can stop a timer, reset another, and so on, and the rest are not effected).I thought of using a single timer and then creating a custom egg timer class to handle the countdown, store the current time, etc, and use a collection of these classes inside a timer event (at the tick, do a for each to reduce the countdown on the classes by some milliseconds).Then I got to thinking: all of these egg timer classes in the collection with the for each loop may cause some accuracy loss (say, I add 50 egg timers).
Does anyone think the accuracy loss for updating all of the egg timers would be too adverse? Should I try running them on separate threads (have not thought about how yet), or will that make much difference?
Create A Nested Loop With A Variable Amount Of Nests?
Aug 28, 2009OK, after trying to get this working for a couple of days now I decided that I would turn to the experts here. I am trying to create a nested loop with a variable amount of nests. Let me elaborate. I have a program that first asks for the minimum and maximum amount of loops, I currently have a SELECT CASE statement that addresses each level of nesting individually.

.net - Amount Of Write Line Instances Vary Depending On YVAL Variable?
Nov 30, 2010I have a mesurement that could be any random value, just for fun well make that 2440mm i need to divde that by the industry standard of 610mm which comes out at 2440 / 610 = 4
Programicaly written NEWVAL = YVAL / STDVAL
NEWVAL (4) gives me refrence to how many instances I want to append a new line in a txt file I know that I want the first line to say 0,0,0 and the second line to say 0,610,0 the third 0,1220,0 the fourth 0,1830,0 and the last 0,2440,0, though this is easily achived with addition how can I automate vb.net to produce a new write line for each each instace of 610 if the YVAL is user defind.Put in simple terms half would be missing if the YVAL variable is double in length at 4880mm?

Get Amount Of Money User Has And Doesnt Go Over Amount Hechecked
Jun 7, 2011im trying to make a fast food program on which the user will input the amount that he has, then he will check on what he wants, by using check boxes. There are 7 different check boxes with 7 different amounts of money. I have the program somewhat finished (thanks for the people that helped me before) but theres still a couple of things that I still need to get finished but I dont know how to.I need to be able to get how much money the user has (this will be entered threw a text box, I think I accidentally messed this part up, because I cant get it to work right, (theres alreasy a permit amount of money in there and it needs to be what the user enters instead of the permit, 5.59, one) and this will be the maximum amount he can spend, then the user will check on the food he wants (and the program will add the sales tax also) then it will produce an answer saying if you have enough money or if you dont. But what im confused on is how do I get the users amount of money and make it the maximum mount he can spend and make sure it doesnt go over the amount that he has checked.[code]

Initiate Internet Data Connection On WM6 Devices?
Jun 22, 2010I am currently porting (well really totally re-writing) a project to run on WM6 devices. I need to initiate a GPRS data connection (or any internet data connection really, shouldn't matter if its GSM or CDMA) before I can get the data I need (actually sync. a database over the cell network - Sybase via Mobilink) because right now its basically saying I have no network connection when I make the call to sync the db.
If I open Internet Explorer on the device, it initiates the data connection, and I can then go back into my program and get the data no problem. This isn't an acceptable solution however.
How can I initiate the internet data connection?
Using A Central Startup Routine To Initiate Several TCP Connections?
Jan 6, 2011I'm using a central startup routine to initiate several TCP connections, start up a background thread that does some monitoring, and instantiate a group of objects that track information throughout the lifetime of a networking session.
There are periodically server-side problems with the protocol I'm working with, at which point the whole mess has to be torn down and set back up, so at the front end of the startup routine I'm disposing of instantiated tracking objects, killing the monitoring thread, and disconnect/close the existing sockets (if they're already set up). At that point the sockets may be in the middle of an asynchronous send or receive operation, which is causing system exceptions when the socket is torn down and then the asynchronous delegate gets called and EndSend or EndReceive thinks there isn't an object there anymore.
I had assumed .Disconnect and .Close would take care of these async processes, and I'm a little lost. Is there some one-shot method I can use to abort those async operations before I tear the sockets down to re-instantiate them?It never hurts to try. In a worst case scenario, you'll learn from it.
.net - Initiate The Current Httpcontext When Accessing An Asp.net Library From A Service?
Jul 27, 2011I have an asp.net project that's compiled on a server. On that same server I have a windows service that's running methods referenced from the asp.net .dll. Everything works fine except for when the httpcontext.current object needs to be accessed. I'm fairly certain that the cause of the .current being null is that it's referencing the shared library without an actual instance of the site running. In a previous version of the service I was able to find a workaround in asp.net by not using the context, however that is now a last resort as much of the architecture of the site has changed. Is there anyway to create an instance of the site and simulate a current httpcontext for the purposes of the service?

Initiate Copy Command On Multiple Files And Add The File Paths To Listbox?
Jan 19, 2011I created a Right-Click Menu option for files. When the user clicks the menu option it will copy all of the file paths to the clipboard.The following function I have will retrieve all of the filepaths to the clipboard. The problem lies in adding the filepaths to the listbox. If I turn single instance application off the result is multiple instance of the application for each filepath. Say for example I selected 2 files and clicked my right-click menu, I wind up with 2 instance of my exe with each file path added to the listbox, 1 in one listbox, the other file path in the second instance listbox.
Public Sub getthepath()
Try
Dim thefilepath As String
[code]....
Is there a way to loop through each file path from the clipboard and add them to the listbox through a loop?Several times I have tried different ideas I had that I thought would do it and I got odd results but never a good result.
