23430 seconds = 06:30:30 (hh:mm:ss)52230 seconds = 14:30:30 (hh:mm:ss)The problem occurs when my total seconds goes over 24 hrs. So for example,95430 seconds should equal 26:30:30 (hh:mm:ss) however comes out at 02:30:30.Here is the sample code, note I have tried using TotalHours, TotalMinutes TotalSeconds however this does not give the correct result. I potentially need to be able to calculate upto 1000 hours - e.g 3601839 should equal 1000:30:30 (hh:mm:ss)
Dim ts
As TimeSpan = TimeSpan.FromSeconds(95430)
Dim hours

A few years ago I have been busy creating this application but it didn't succeed, now Im coming back to it and similar problems occur. Basically I use SetPixel on a given window to draw a line, work fine, but the line goes away as the window redraws itself.The problem: I have been putting timers and threads on it to make sure the line is being drawn. Is there any way to make a loop to make a certain thing happen about 10-30 times without taking in too much memory/CPU?

i was wondering if theres a way to make an if command apply to more than one thing, this is my problem: theres 9 white squares and if theres one or more thats orange, then a numer.text goes down one but at the moment theres 9 white squares and for every one thats orange the score goes down one, so if three are orange then the score goes down by three, or if five are orange then the score goes down by five, I'd like to make it so that even if there all nine the score only goes down by one.

View 2 RepliesI want my application to be able to communicate 2-way between the application on another computer and the host server which will be running on my computer.I want to use the BackgroundWorker built into vb to create a thing to make it listen for incoming messages, and also send out messages to the client.The client needs to listen and receive, same as the server, because both need to communicate with one another.I do not know how I can make it do either sending nor receiving.I would be using two different background workers to keep the code seperated and organized so that I will understand what code is for what.
I want the code to say that if i receive the message "Apple" without the "" and cap sensitive, then it will change Label1.Text = "That worked, word received Apple" or something similar to that. ( This is because I am ignorant and I want it to interpret the text sent through to figure out what the application is supposed to do, and last time I couldn't figure out how to make it do something when a certain text was received.

why the title has "(con't)" is because of this Form Resize With Control Sizing... almost named it with another thread on here. And I wanted to post, but it was already a 'Zombie Thread'.Thanks to _HAWK_'s post #11, instead of declaring every control I use. Would declaring it an array (fast guess - Label<Array(how many - 1; aka - X)>) work? ... that was probably Java... My point has probably been made, or can I just do Label.Scale(variable)?I had already set my declaration of the form I need to do this on "Resize". I am not quite at this stage yet, but I see this saving a lot of time asking early.
The +1 extra question is:How can I be able to split of a form in 3 unequal sections? The initial form is 800*600-left side has 2 sections, each 400*300 right side is 400*600.I am already using 3 'GroupBox' and it looks ugly because I have each one colored differently.I looked into Splitter and SplitContainter and TableLayoutContainer.
What i want to do is not allow the entering of the same thing in the same field that has already be used. eg. field(entry) 1 is already in the database. So when trying to enter 1 and field(entry) anymore it will give error msg and make change before saving.

I've recently converted some VB 6 code over that used the old non-structured exception handling. I also have some .NET classes that raise custom exception classes. When the code was VB6 I used to expose my .NET classes using COM interop and errors raised from .NET classes were being caught correctly in VB6. Now that everything is .NET the old non-structured exception handling is still there in the converted classes. But now the Err.Number is not reflecting the HResult of the error raised. I wrote a simple little Windows Application form with 2 buttons to simulate the problem. Here is the code snippet:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
On Error GoTo ErrHandler
Err.Description = "Test Error"

If you click Button1 you get the following message:
-2147215379 : Test Error
If you click Button2 you get the following message:
5 : Test Exception

Such as with using Visual Basic 2010. what is an easy simple program to make? Like making your own calculator or whatever.If I even tried fiddling around with Visual Basic 2010, I would change Form1 to the name of the thing that I am creating, along with changing the color of the foreground/background and the color of the text too.But its the command text where I have to add text to make it work too that I would have trouble with. I ain't smart when it comes to stuff like Visual Basic.

I read somewhere long ago, that it's better to assign the method to a variable and pass that variable to a method, as opposed to passing the method as a parameter. Is that still true? Or true at all?

can someone give a example of doing bubble sorting with numbers the simplest way if possible.all i know is that it uses a boolean to stop sorting, a variable which records how many swaps are done in a run if its 0 it stops swapping but other than that i dont know how to write a program doing bubble sorting?
my teacher didnt give me any examples of bubble sorting other than a algorithm, and before u ask no its not for homework i am looking bck at my computing notes and i just dont understand any of it!
if u could explain it to me step by step and give a simple brief exmaple using numbers
