Find Particular Items In A List Box?
Feb 22, 2011I am writing a program using editable list boxes that will then be compared to a string later. I have no problem editing the listbox, but I am having trouble figuring out how to compare the list of things to the string. I envision using either a "for/next" loop or a "do/while" loop.
Mostly, what I need is the way to read the list box one entry at a time, in order.

Program That Will Compare Array Of Grocery List Items Glist And Array Of Coupon Item List
May 27, 2012I have a program that will compare an array of grocery list items glist and an array of coupon item clist.When I compare the two and if there is a match somewhere in the array I want to have a picturebox visible.When there is no match, I want the picture box not to be visible. [code] The code seems to work great until I come to the else statement.When the code finds a match it displays the picture box and the msgbox without error, but as soon as the message box is cleared, even though i've input it as an ELSE statement, the picturebox goes false again.Does anyone have any idea of how I can "hold" the picturebox to stay visible while the match between the arrays exists?

View 4 RepliesWay To Select From A List - Aren't The Two Listboxes Getting A Little Old?
Dec 22, 2009How many times have we seen this type of selector:
I was just about to start creating this in a WinForms app, when I thought that others may have some ideas for doing this better. We need it to sort - so the right hand list will need up/down buttons. But this seems so old school. I love devexpress components, and was thinking of asking them if they would consider adding a component that handles this functionality with a slick UI.
I am thinking that a graphical representation of the objects, and a graphical representation of the listboxes - that would be a more intuitive way to move items around. Has anyone seen an open source project like this?

Forms :: Make A Program That Reads Text Entered Into A Textbox And Creates A List Of Items By Separating Entries By Commas?
Aug 18, 2010Hi, I'm working on a program that reads text entered into a textbox and creates a list of items by separating entries by commas. Everything is working fine, except, because I am using an array to store the items in the list, I have a limited number of entries. This is only a problem because, as it is written currently, each comma counts as an individual entry. Therefore, users can enter ",,," for example, and it would use up 3 places in the array.
I'm looking for a way to check to make sure there is text after the comma before adding an entry. I've attempted to use the .substring command to check the character after, which works until it gets to the last character. Because there is no character after that, it will give an error.
Here is my code for extra clarity:
Public Class frmMain
Dim intCounter As Integer 'Stores the # of commas in the string
Dim Messages(49) As MessageProperties

Determine If Property Is Generic List<of T> Via Reflection And Loop List Items
Oct 1, 2009I'm looping all the properties in an object via reflection:
For Each p As PropertyInfo In values.[GetType]().GetProperties()
If p.CanRead Then
'Do stuff
End If
Next
how to determine whether the property in question is a generic List(Of T)? If it is I need to loop the list itself.
I've experimented with GetType and TypeOf but have not managed to get anything working.
To clarify, I want to keep this generic. I do not want to specify the type of T, I need to loop the list items and call the ToString method on each item. T could be one of a number of different types (application specific reference types). Is it possible to do this without specifying types?

Shuffling Items Inside A Movie List / Need To Delete Half List
May 16, 2011Another program I am working on for fun, I am basically shuffling a list inside a listbox, what I want to do is delete the rest but not sure how to go through with that. At the moment I have this: [code] Just contains the code, declarations outside weren't included.So anyway, once clicked, it will call on the function to basically shuffle in a for loop, I was wondering if I should (or how should) create another function and call it in the click button or have just a loop in the click button so it deletes half the list. What I am doing is I have 20 list of items, I want the program to shuffle the items and then deleting the lower 10, meaning, if I had 10 items and wanted 5 top, I'd want: 0, 1, 2, 3, 4 and deleting 5, 6, 7, 8, 9.
