I am using the following code to create an array consisting of double values specified by start stop and step. The problem with that is that for some weird reason there is a calculation error that seems to originate from the for statement causing the values to drift after the 11th to 12th digit after the comma which is quite irritating for the purpose i am using it.

what is the method to tell when a user starts or stops a process? My company makes a software package that allows a tie in from vb. I want to make a package to allow me to start and stop the software remotely and to monitor when the software is running or not.Ideally there would be some sort of event in windows when the user starts or stops the software. I imagine there is some sort of way to do this with a timer, but I am sure that windows will have some sort of event process when the program starts. I have googled this and looked through the xtremevbtalk forums for this but I am not quite sure as to what keywords to use.
View 3 RepliesI am a total newbie when it comes to VB but I'm starting off with a few simple projects I've completed already! Basically Ive seen MANY stopwatch tutorials but none so far have been able to do a simple format of Second and Milliseconds 00:00 and NONE have been accurate in the slightest and have been totally off! create a simple stop / start stopwatch that is actually accurate that would be great as Im going around in circles trying to find a tutorial on this!

how do i create an array with known values for example this is what i want to do
Quote:
dim str as array
str=("!", "@", "#", "$", "%", "^", "&", "*", "(", ")", "~", "_", "+", "|", ":", "<", ">", """", "`", "", ";", "'", ",", ".", "/", "-", "=", "{", "}", "[", "]", "?")
but that doesnt work in vb 2008.so how can it be done without using a for loop and entering each value in step by step Also what exactly does

So I'm opening a TCPListener on socket 8000. Debugging code, finding bugs, stopping the app and debugging again. Somehow I'm causing a problem such that it's not closing the TCP port, and it's causing a major problem such that even after I stop my program and restart it the code to open the TCP port the app is still throwing an exception, and it keeps happening until I reboot.It's going to be real hard to find the bug when I have to reboot each time to debug the app
View 6 RepliesI know how to create an array and loop through it normally - but what if I need a multi-column array. e.g. usually I might do something like:
For Each row in NameofArray
Dim name as String = row
Response.Write("Hello " & name & "!")
Next
But what if I want to do something like:
For Each row in NameofArray
Dim name as String = row.name
Dim age as Integer = row.age
Response.Write("Hello " & name & "! You are " & age & " years old!"
Next
If this isn't possible with an array?
in order to create fancy custom end caps on the ends of a line, a structure like the following can be used:
Dim pts() As Point = {
New Point(-2, -2),
New Point(0, 0),
[Code]....
be used to create the same point array. I can see splitting these values into an integer array but how would these in turn be placed in a point array of whatever size is defined by the text values so they can be converted to end points of a line that is developed as values are changed in the text box.
I am running Microsoft Visual Studio 2008 Professional on a Windows 7 system. While working on the visual basic exercise in chapter 4 of the Microsoft Visual Basic 2008 Step by Step book on the MyMenu program I added a Toolstrip to my form and then I was trying to perform the add OpenFileDialog and ColorDialog controls to the component tray as described at the bottom of page 111 under Using Dialog Box Controls. I could never get the controls to appear in the component tray as instructed in the book.

I have a program that plays a video and uses the step function to move frame by frame backwards and forwards through the video. The forward frame works just fine:
AxWindowsMediaPlayer1.Ctlcontrols.step(1)
However, the backwards step (below) jumps a full second backwards while the forwards step only steps .033 seconds forward (presumably a single frame).
AxWindowsMediaPlayer1.Ctlcontrols.step(-1)
I can't find any documentation about this problem online and in fact I can't find much mention of this function.the documentation does say the -1 command should step back one frame. IWMPControls2::step method Is this a known bug or is there an updated function I should be using?

I enforced this behavior by disabling/enabling "Next" button, but I really do not like this solution, since it seems not really elegant or safe here. What is the good approach on building step-by-step processes with enforcing step completion.
