  1. Re: Help Erro Null reference exception was unhandled

    When that exception occurs, examine the line where the exception happens. One of the objects is Nothing. Finding that object is the first step.

    In this case, the exception appears to occur on...
  2. VS 2013 Re: [RESOLVED] Where to declare Points to be drawn on control surface.

    Well, yeah, THAT will work, but I thought you wanted to avoid that. What you are doing there appears to be creating a whole bunch of points each time the Paint event is raised (which can be often),...

    Re: Message Box "OK" Hijacked by Timer

    Technically, I think your reading of the question is right. Originally, I was going to make a similar post asking what "it" is, since the subject should be the form, but I think it probably is not. I...
  4. Re: Help Erro Null reference exception was unhandled

    I suspect the problem is that you are running on a 64-bit OS. I don't speak the language, but I do speak code, and I think there is enough in what you posted to say that you are getting the exception...

    Re: DirectX to XNA

    I have never needed to do anything with either item. Therefore, while I would say that neither one is required with XNA, having never had to stumble over those bricks, I can't be sure it wasn't just...
  6. Re: If you like your Ebola, you can keep it

    What spreads FAR faster than Ebola is fear:

    Re: Message Box "OK" Hijacked by Timer

    When you say that the button "refuses to do anything", does it REALLY do nothing, or does it appear to click...and nothing happens?

    Aside from that, I would note that MsgBox has been replaced with...
  8. VS 2013 Re: I can't run my VB.Net Program In Any Other PC! Here is the Error [Help Please]

    I didn't think that would cause failure on other computers, and it should have shown up when you built the exe, but the solution is pretty straightforward. Most likely, you have left the Target CPU...
  9. Re: If you like your Ebola, you can keep it

    I believe that was posted here on the forums at some point.
  10. Re: How to Show changes made to Form in VB2010

    That makes sense, but it doesn't make it easy. It sounds like there is no event that App1 can detect that lets them know that App2 has closed and that updates are ready. It seems to me that you have...
  11. Re: If you like your Ebola, you can keep it

    I didn't have time to write a short statement, so I wrote a long one.


    By the way, I was thinking of water drops: Two water drops added to two more water drops results in one (bigger) water drop....
  12. Re: If you like your Ebola, you can keep it

    No, there was no doubt in MY mind, but that's kind of my point. We communicate well enough that we expect that we are getting through to 70-90% of the audience. We probably feel that we are getting...
  13. Re: App Deployment with SQL Server Express

    Darn, I was leaning away from that, but you make a good argument.

    This would certainly be a more involved installation package than any I have written. All of my programs for years have been...
  14. Re: FOR..NEXT loop to calculate the sum of n user-inputed values

    One of the issues we have with a question like this is giving an answer in terms of things you have already covered in the class. This is a fine situation to make use of a List(of Integer), but the...
  15. Re: How to Show changes made to Form in VB2010

    On the face of it, the problem doesn't sound all that difficult, and it sounds like you almost have it already. Whatever is happening when you close App1 Form and open it again, needs to happen in...
  16. App Deployment with SQL Server Express

    This is something I haven't done, yet, but the more I think about the specific situation I am encountering, the more I am torn as to the best approach, so I figured I'd ask about it here:

    The...
  17. Re: If you like your Ebola, you can keep it

    We live in a world of shorthand discussions. Technically 2+2 does NOT equal 4, except in certain situations where it does. However, we use the phrase as a shorthand for something everybody knows to...
  18. Re: If you like your Ebola, you can keep it

    I'd be more of a fan of ad hominy reasoning if I didn't find it so corny.
  19. Re: Pairing up developers for enhanced learning and better productivity

    VS 2013 Re: How to shorten a decimal number?

    A label is a string, not a number. You may see it as a number, but it is still a string. I think this was covered in a different thread, though, and the answer there was the best: The number was...

    VS 2013 Re: Where did my stuff go?

    I've never seen anything like that on any of the systems I run VS on. It certainly isn't normal.
  23. VS 2013 Re: [SIMPLE] New to VB - Very simple question (I assume?)

    Yeah, that would make a difference if the numbers are bigger or smaller by an order of magnitude. You should have mentioned that originally, as it would greatly impact the answer. No fixed division...
  24. Re: If you like your Ebola, you can keep it

    Gee, I misread it. I thought he had appointed an Elbow czar. I wasn't sure if that had to do with the macaroni scandal from the US revolution, a commission on repetitive strain injuries, or something...

    There sure are lots of those formatting arguments for .ToString. It's hard to keep them all in mind.

    Re: Communication DB Location

    Yeah, that's possible. It would only slightly reduce the amount of packet traffic, though, since there will rarely be more than one or two systems at a time, and it removes the potential to do some...
  27. VS 2013 Re: Where to declare Points to be drawn on control surface.

    Then that's the way to go. The properties will be set after the control is created, but during the form creation. I have considerable doubt that setting the points at that time is late enough in the...
  28. VS 2013 Re: HowTo Make This Code Read Some Fields From a TextBox(s) [Simple!]

    In what way is it not working? Are you getting errors? Are you getting incorrect results, if so, what are they? Have you put a breakpoint in the code and stepped through it to see what is happening?...
  29. VS 2013 Re: Where to declare Points to be drawn on control surface.

    It may not, too. Those properties may end up being set too early in the process for the values to be valid at that time. A bit of trial and error should answer that. The custom control could also set...

    You have a couple alternatives, and unfortunately, you have used both of them together. Here are the alternatives:

    1) Fill a datatable with all the records then, when you need one, you search the...
  32. Re: If you like your Ebola, you can keep it

    Yeah, it should, but that response has to be in Africa. You have to go to the source and deal with it there, which is happening...to an extent. HUGE amounts of money are being put up, but what is...
  33. VS 2013 Re: Where to declare Points to be drawn on control surface.

    That's the override I was thinking of. However, in the Set part, you'd also have to create your points there. After all, you are currently setting the points based on Me.Height and Me.Width long...
  34. Re: Pairing up developers for enhanced learning and better productivity

    To be fair, the link wasn't really about SCRUM.



    This is a good point, in my case, as I work with other developers only to the extent that I say hello to them in the halls. We barely even know...
  35. VS 2013 Re: Dispose large number of controls quickly? or better manage resources?

    While I like that approach, I wonder whether getting rid of the pictureboxes is even the best solution? You've already seen that disposing all the controls has a cost, as does creating them. You...

    VS 2010 Re: Not enough heap memory issue

    2.5 gigs? That's a heap of memory!

    On a more serious note: You appear to have tracked it down to its source as best as may be possible. I'm not sure what can be said about that, though, because it...
  37. VS 2013 Re: [SIMPLE] New to VB - Very simple question (I assume?)

    That worked? You originally posted:

    which is 142 million plus some. You divide by 1 billion (10^9) and it works? 142 million divided by 1 billion is less than 1. What kebo suggested...

    VS 2013 Re: How to shorten a decimal number?

    Another alternative is just .ToString("N2")

    There are lots of formatting options for .ToString. I like "N" because it will add thousands separators if the numbers get that large. The 2 means that...
