VB 2008 Loops And Comparing To 0?
Jul 5, 2010I've had no issues with this in C++, however, in Visual Basic 2008 (not sure about 2010), when I run a Do loop of any type, and run a comparison to 0, or even 0.0, the code loops a second time.
[Code]...
To my knowledge it should cancel after the 5th line, since the condition is satisfied. However it does not. Instead it runs the loop one last time.If I put in a comparison of any number higher or lower than 0, it works as it should, and cancels properly when the 5th line is written. So 1, -3, 0.0001, etc. works, so the problem lies with 0.
Now I do not know that much about the debugger, but it should be mentioned I'm running express edition, and I could not find anything that lets me see how each line compares. Nor, after an hour of searching online, could I find a single forum where this is answered (though perhaps that is due to how I worded my search).
If someone could explain to me why the comparison does not work as it should and loops a second time when comparing to 0, or even 0.0 (one person thought it was a difference in balance being double and 0 being an integer),

Apr 13, 2012This is the code I have in one button and I have 2 listboxes that will be filled with the info it gets.This code should compare 1 avi file to one jpg file and see if they have the same name. If YES then it will add the avi path to one listbox. If they don't have the same name OR the .jpg doesn't exists it will add avi path to another listbox.. But currently it is adding the avi name to both listboxes.

VS 2008 - Comparing Variables In Private Sub With Public Class
Nov 11, 2009I have these list of RS-232 strings declared in my public class
Public Class TouchInterface
Dim WatchTVbtnCmd As String = "rs232command1"
Dim VolUpbtnCmd As String = "rs232command2"
Dim VolDownbtnCmd As String = "rs232command3"
Dim SystemOffbtnCmd As String = "rs232command4"
Dim RadiobtnCmd As String = "rs232command5"
Dim MusicbtnCmd As String = "rs232command6"
I then have this private sub. For the sake of this thread, what I would like to do is get the name of the label that was clicked which in the code below is already done, convert it to string (not sure if this needs to be done), this is also done in the code below. Next I want to compare the labelnamestring to all the variables in the public class to find out which one it is equal to and then disply that variable which should be my rs232 string in the message box. I have also added "Cmd" to the variable names above so I also need to work out how to add the text "Cmd" to the string to properly compare.
Private Sub Musicbtn_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles WatchTvbtn.Click, VolUpbtn.Click, VolDownbtn.Click, SystemOffbtn.Click, Radiobtn.Click, Musicbtn.Click, GardenVolUpbtn.Click, GardenVolDownbtn.Click, GardenRadiobtn.Click, GardenOffbtn.Click, GardenMusicbtn.Click, GardenMediaCenterbtn.Click

VS 2008 Adding Or Comparing Faster At Binary Level?
Sep 16, 2010I was just wondering if a computer would add two numbers together (positive) faster that comparing two numbers.
I was thinking that it would be comparison (best case) due to the fact that the 0th bits could be different right off the bat. Where as when adding, moving from bit 0 to N is mandatory for addition.
But then again a computer may add/compare differently than I am imagining.

VS 2008 Comparing Picture Boxes And Textbox Information?
Jan 8, 2010I'm trying to make a Lottery program on visual basic 2008, but there's one thing that I am stuck with.Note: My explanation may be hard to understand, so if you would rather have me send you my code and see how it works, I'm fine with that. My code is pretty long so far, so I didn't know if i should post it on here.
My program has 6 picture boxes lined up horizontally, and has one text box underneath each one. There is a play and stop button on the bottom left corner.I've altered my program to have animations for the picture boxes. Instead of having a random picture picked, I have it so that each picture box scrolls through a series of 10 numbers when the user presses play.
When the player presses stop, the picture boxes stops scrolling, and random pictures are displayed in each box. (The picture is really just a black circle with a number in it).The text boxes below the picture boxes are for the user to put numbers in. These are the numbers they select for the lottery. Now this is my predicament. Since the picture boxes decides what the winning lotto numbers are, how can I compare the numbers in the text box to the pictures?
Forms :: Find If Times Is Between 2 Times?
May 13, 2009I have just started using vb.net and I have a checked list box with times throughout the day shown as
00:00 - 00:14
00:15 - 00:29
00:30 - 00:44
00:45 - 00:59
What I am trying to find is a way to get the current time and find which list item it fits into. What I think I need to do is to first of all get the current time and then go through the list splitting each item into 2 times and seeing if the current time fits. For example: Split the item 00:00 - 00:14 to 00:00 and 00:14 and then check if the current time is more than 00:00:00 but less than 00:14:59 and if so do certain task.how to go about taking each list item and splitting it into 2 separate times so I can check between them?

May 17, 2010I am trying to write an app which allows the user to input two times , in a maskedtextbox, and take those two times and add them together then output the result to a third maskedtestbox, I havent seen anything else on the web with the same problem, only with fixed date or time, nothing that the user can change.
I am guessing you have to input the a maskedtextbox as a string then parse them to datetime, add the two together and the convert the date back to a string at runtime my code always bails out with a datetime conversion

VS 2008 Very Different Times For The Same For Next Loop?
Sep 15, 2010I have about 1.000 text files in a folder, and I wanto to make some statistics reading the files content.In the first place I store the files path + name in a MyFiles() array, then, when I press a "Start" button I read the several files:
For x As Integer = 0 To MyFiles.Length - 1
FileReader = My.Computer.FileSystem.ReadAllText(MyFiles(x))
(data processing)
(data processing)
next
then I have copied and pasted the first 500 files in a new folder and added to the code if x > 500 the stop The strange thing is this: to elaborate the 500 files of the second folder takes about 4 seconds, to elaborate the first 500 files of the first folder (THAT ARE IDENTICAL TO THE 500 FILES OF THE SECOND FOLDER) takes 7 seconds.The same identical code takes different times to elaborate the same identical files if they are stored in different folders with different files number.
