View 1 RepliesI'm using Visual Basic 2010 express, and I can't seem to be able to figure out how to make a button_click event select all of the checkboxes in a CheckedListBox. For example, I created a checkedlistbox with about 34 entries in it, all of which can be checked. So I decided, to make it easier, I would just make a Button with "Select All" on it, but I don't know what kind of button_click event would select all of the items withing my checkedlistbox.

View 6 RepliesI'm close to getting this to work, but currently can't get any output to display in the listbox. I had it working, but needed to move some things around to get the join function to work.In my program, a user enters input into a textbox and an array is displayed in a listbox based on what they type in. For example, if they type in "a", all foods (in the textfile that is connected to the program) that start with "a" will be displayed.
When there is output, I need to find a way to name this array (which is created based on what the user inputs) and join all of the items in the listbox (example: foods stacked on top of each other in the listbox will be shown at the bottom as a string).I am posting the code that I have thus far; all of the errors that I'm getting (and potentially my logic errors) are just in the first public class until the end of the first if-next statement:
Public Class frmFoods
Dim foods() As String = IO.File.ReadAllLines("foods.txt")
Private Sub btnDisplay_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDisplay.Click

View 2 RepliesThe gist of the program is to:
- Read a CSV file into an array
- Get this visible in a list box, so the values can be:
- Sorted
- Edited
- Deleted
- Added
- Finally save these manipulated values back to the text file
Would love some suggestions and code as to how to get this going, hopefully I'll get the hang of it and come back and fourth for help

I've read thru Iceplug's tutorial on control arrays and got it working. I tried to add a new event by basically copying his click event code and calling it a doubleclick event. I used the proper addhandler and assigned the correct name to my sub. I have the click event changing the background color to blue and the doubleclick event changing the background color to green. The background color does not change to green. Why?
Heres the tutorial with my new code encased in asterisks ...

I have to write a program for a user to take a 20 question test (A, B, C, D). The users answers will be stored in an array and compared with a 2nd array that has the correct answers. Its then supposed to go to a 2nd form when you click show score, grade it, and display whether each answer was right or wrong. I'm missing something easy probably.

I'm trying to make a show/hide button. I want the show hide button to be attached to an object on a form. Right now I just have separate show/hide buttons set the 'visible' property to true/false respectively. I want to code something that will consolidate the two properties. But I don't know how to code an if statement into an event, in this case the click event.
I'm thinking I'd have to do something like create an array (which I'd have to read a tutorial on first) that would hold two numbers. So, if the object on my forum's default visible property is true then if the button was clicked once it would be set to false (1) and clicked again it would be true (2). So, the array would only remember two values (1 and 2) and I'd have to create something else that would remember the previous value (say, 2) and than get the array to spit out the only other value (say, 1) it holds. Then finally strip the value the array spit out and have it go through some kind of if statement that would set the true/false value.
Without posting the exact code I'd need to pull it off, how would I go about doing this? Am I on the right track, or is there a simpler way? I'm new to programming.
Can I save an array into my .bin file then read the array again just like a string or Integer??
