VS 2008 Comparing Version "strings"?

Aug 25, 2010

I cant seem to think this morning.I am trying to compare version strings. These are scraped off a website...

examples:

4.5.0.55
4.2.2.128
4.5.0.37
5.0.0.713

how do i make sure I am grabbing the highest version?right now I have it checking the length, if less than 9 .. add a zero. then remove the .'s and convert to an integer. then just check. I know thats not the best and most accurate.

VS 2008 Comparing Strings?

Aug 10, 2009

Hopefully this question will have an easy answer; I've tried searching for the answer myself, but I don't know what to search for (I don't know what you would call this).

Is there a way to compare a string to see if it matches more than 1 value?

Comparing Strings In A Listbox?

I'll use this image to illustrate my question.

Basically, how would I go about it searching through the listbox for "String 4" and then a messagebox coming up?

But, if it doesn't find that string an error message comes up.

VS 02/03 Comparing Strings That Contain Quotes?

Aug 18, 2011

I'm trying to compare the selected item in a combo box to the items in a collection in search of a match. There is guaranteed to be a match because the combo box was originally populated from the same collection. This is the code I'm using:

[Code]....

This code works for other collections but not for this one. In this case, the loop stops after the first iteration, regardless of what's selected in the combo box. I have confirmed that the collection contains the correct data and that there is a match for the combo box options. The only difference between this instance and other instances is that the values in the collection and in the combo box contain a double quote at the end. I suspect this is what's causing the error. (To be clear, there is no error message, it's simply not returning the correct value.) I've tried various string compare methods but none of them have fixed the problem.

How they relate and differ from each? What are the best practices for version control? Is there a primer about publish online? Or a good book?

And is it possible to make ClickOnce and a msi in one solution of VS 2008? If so, is there any conflict or pitfall?

BTW I am using VB if that makes any difference.

Comparing Large Array Lists - Matching Strings?

Apr 26, 2011

I have two array list same size, depending on the information gathered by previous functions. The size of the arrays range from 2 - 45 in length, both arrays always have the same length. I am trying to match one string in one array to another string in the second array. When they match then add Item to List.

Here is my
Do Until i = Arraylenght
info = Replace(myAL(s), " ", "")
SortedArrayList(m) = Replace(SortedArrayList(m), " ", "")
SortedLine = Split(SortedArrayList(m), "Price=")
If myAL(s).Contains(SortedLine(1)) Then
[Code] .....

This code works up to an array of not more then 4 in lenght, when working larger size array then 4, the minute it get to 5 I get this Error:
Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index

Comparing Lists Of Strings - Copy And Display Elements?

Dec 20, 2009

I have two lists of strings. One is a list of all students in a class and the other is a list of students in the class that completed an assignment. The two lists are part:whole. So we have two loops for copying elements and displaying them in a list box for only the students who did submit.

Dim f As Integer
f = 0
Dim h As Integer
h = 0
While (usersinclass.Count > f)
h = 0
While (usersidthatsubmittedassingments.Count > h)
[Code] .....

What I need is the remaining portion of the "usersinclass" list. (i.e. The students who did not submit). I tried an Else statement BUT with nested loops, every element is guaranteed not to match at least once, so I was getting elements that shouldn't be there. So, is there anyway to run the given lists against each other again to pull out the remaining students? (preferably with no repeats).

VS 2008 Check Difference Between A Full Version And Unregistered Version?

Sep 1, 2010

I have created a license system for my application with MySql about half a year ago. What it would do is take the serial number and send it to my server if the key was correct it would return a 0 if its wrong the return value would be a 1.The problem was that when the serial number was entered correctly my program would create a "fake file" for example vb.dll in the system.And on run time my program would check for that vb.dll if the file exist it would skip my trial program and run the app as a full version. Half year later i think creating a "fake file" and checking for it on start up is extremely wrong and that's not very good security.How can i check the difference between a full version and unregistered version?

VS 2008 Using List Of Strings Or Array Of Strings?

Oct 16, 2009

I'm migrating from VB6 to VB.NET, in hence my questions below:

I have to write a function that returns array of strings.

How can I initiate it to empty array? I need it since I have to check if it's empty array after it returns from this function.

Is list of arrays better for this purpose? If I use a list - Is it empty when it firstly defined? How can I check it it's empty?

VB 2008 Loops And Comparing To 0?

Jul 5, 2010

I'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),

VS 2008 - Comparing Variables In Private Sub With Public Class

Nov 11, 2009

I 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, 2010

I 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, 2010

I'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?
