View 18 RepliesI am having a performance issue when adding a large array to a treeview. I am pretty sure that I am using the wrong method but I was unable to find a better way to load the tree.here's and example code of what I mean. this takes about 30 seconds to load into the tree.
Code:
Public Class Form1
Public StringArray(10000) As String
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

I have a quesion about using the timer1 function. I am a complete virgin when it comes to programming, so please be kind. I have a project that is using an NCD relay controller to control linear actuators. I want one relay to turn on and then stay on for 10 seconds and then turn off. I set the timer1 properties to enable with an interval time of 10000. I am programming a button to turn on the relay then wait 10 seconds then turn the relay off. All that happens is the relay comes on then off immediatley. I have tryed to do this several different ways with the same results. It is though the timer1 is not getting recognized. So my main question is, what steps am I missing, and how do I get a delay of 10 seconds before the program recognizes the turnoffrelay command?

View 1 RepliesI was given an assignment to "write a program to print only even numbers between 6 and 16 using events", but I don't even know where to begin. The main thing I am having difficulty with understanding in this assignment is how I am supposed to specify that it only print even numbers in the given range of numbers.
Am I going to have to do a Mod2 code for each individual number and have it exclude any with the result of 1? Or is there another piece of code specifically designed for such an occassion? Perhaps there is some type of equation I can have the program read in terms of a variable, which holds the values of 6, 8, 10, 12, 14, and 16? I am just genuinely confused on how this is supposed to be programmed.
I want to open a txt file and write into it numbers from 1 to 100 and put between every number enter.
View 4 RepliesI know how to declare a variable, a function, to write a string of characters or numbers (I still looking in tutorials and depict from there what i need to know) but...WHAT I DONT KNOW is how to USE them? At "what" or "how" are you thinking when you make a program? I try for SOME LOooNG TIME to understand but I think im too stupid to understand from pages on the net (or i dont find THAT tutorial who can explain right for me).I try a lot of programing languages starting with pascal,c,c++,darkbasic,alice, Visual-c,c#,c++,basic,php,even assembler, some programing zones in Excel and Word but from all of this i cant manage to understand the life behind the words.

I'm currently in VB class at my highschool and we just got chapter 6.1 to read on this online textbook that we follow. Anyway, we are doing loops now and the problem reads "Write a program to request positive numbers one at a time from the user in an input dialog box. The user should be instructed to enter -1 after all the positive numbers have been supplied. At that time, the program should display the sum of the numbers." So far I know this much
[Code]...
Now I know this isn't right But I can't find out how I'd pull out the numbers the user entered to get the sum of them and not include -1 because as it stands, when I hit ENTER with -1 the label just shows -1.
i m trying to write a program that displays in a textbox a table of the binary, octal, and hexadecimal equivalents of the decimal numbers in range 1-222.

I'm looking for an example in VB.NET of a continuously scrolling form. This would be similar to a continuous form in Access but with a major difference in that when you scroll it the whole thing moves up or down instead of the data jumping up or down to the next section. If you are not familiar with Acces, this would be a form that lists data down the form in sections, one per record, in other words, like a bunch of forms strung one after the other. When you scroll down, the record at the top gradually disappears and is replaced with a new one at the bottom.
This needs to be a form with controls, not a datagridview.Right now, I'm trying to find an example of this. I tried searching for one and couldn't find one. Does anyone know of an example of a continuoulsy scrolling multi-record form where the whole form moves in VB.NET?
i need a program that when I press a button on the form, it will display the system time continuously in a text box. I know i need a loop to do this but what I have keeps freezing my program. Heres what I have:
Sub getTime()
Dim currentTime As System.DateTime = System.DateTime.Now
Dim x As Integer = 1
