Reflow A Program As Such That It Won't Be Necessary To Evaluate Everytime?
Nov 21, 2010
change the program flow- so that it ignores certain precedures.Functionality: a form that displays all users. Optionally a user could check a check box and it would display his age. beside it Program Precedure: Now, I have to recheck everytime if it is checked. Is there a way to make the program just ignore a certain line of code(or something, that whatever it is I can't name). And I'm asking that the program should run without any evaluation whatsever?

I have a program that everytime it is started download a file, read to a list, and add an entry to that list.That entry will be the useres ip address. I have gotten that far so far, but the ip address is sometimes the ip address of the lan like 192.168.1.100. That will nto work properly. I want the true ip address like 69.47.192.12

im loading images into 2 picturebox controls My app works as it should but i need to know when i should dispose of the images or does the garbage collector do it for me?on a user click the images change, i think that my app will become resource hungry and cause the app to bomb out at some point.So do i use Picturebox1.dispose() each time new images are loaded into the pictureboxs to free up the image from memory?

I have a multiline label that im trying to add a line everytime I click the button. Its basically adding a new CD track name, CD minutes, and CD seconds to each new line for everytime the user inputs the given information:
1 Track_Name1 3 min. 13 sec.
2 Track_Name2 2 min. 34 sec.
3 Track_Name3 3 min. 01 sec.
.
.
.
But it keeps adding the "new" line in the position of the old one, so its only displaying on 1 line. I tried using a vbCrLf, but I might have it in the wrong spot?
heres what I got...
Private Sub btnAddCut_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAddCut.Click
cutCounter += 1
[Code]...
The cutCounter is obviously the track number, and it clears the current info for the new information.

if i do not need to evaluate all the expressions, am i right to say that there are benefits and no disadvantages of using AndAlso compared to using And
example:
if a=b And f=g And y=k
can be better done with:
if a=b AndAlso f=g AndAlso y=k

This is probably a basic question, but I have never used this syntax before. Can someone tell me in detail how this expression evaluates to true? [Assuming IsOdd is a boolean type].
Dim i As Integer = 3
IsOdd = (i And 1) = 1

I've got a global random type variable, let's call it rRandom.In my code, I generate a random number like below:
Dim iRandom As Integer = rRandom.Next(0, x)
9 out of 10 times iRandom is 0, the other time it was 1. The code isn't on a timer, it happens when I do something (say clicking a button), so the frequency of the code being called is about 2-3 seconds, I say this because I've had similar issues when generating random numbers really fast in a timer, or with a for loop IIRC.X is a variable that, presently, starts at 3, and will decrease until 0, in which it'll return back to 3. Obviously, if X is 0, iRandom will be 0, but it shouldn't be 0 all the time.I'm declaring the variable globally because I remember, again, having similar issues using local variables, idk whether I should be or not.

So I am trying to evaluate 3 conditions in an if statement. Its not working how I would assume it should. I basically want to do this:
vb.net
If PGN = &HEF007E And PGNData(0) = &H58 And (PGNData(1) And &H40) = &H40 Then IgnOn = True Else IgnOn = False
If I write it in that manner it gives inconsistent results. If I workaround by writing it this way it works perfectly:
vb.net
If PGN = &HEF007E And PGNData(0) = &H58 Then
If (PGNData(1) And &H40) = &H40 Then IgnOn = True Else IgnOn = False
Endif
What is the proper way to do this with only one if statement?

I have functions in my program that stop after it reaches a Return line but I need the function to continue in case what I want the function to return changes. Is there a workaround for this or a way to force the function to continue after a return?
I made a Test Program to demonstrate the problem. It is a Form that contains only a button.
Here is the source code:

The messagebox always says "It returned False" when if it continued going through the code like I want it to it would have returned true.
