View 4 RepliesThis program is supposed to allow the user to check items in a checked list box. If the item is checked, it goes into the Completed List Box on the right. The program then adds the unchecked items to the Pending list box on the left. I keep getting placement values (e.g. O,1,2) instead of the strings (e.g. "Key Returned") in the list box results (see photo attached)
Public Class frmCheckOut
Dim i As Integer
Dim cleaning As String = "Cleaning Inspection"
Dim damage As String = "Damage Repaired"

How do you count the amount of values in a list box that are selected, rather than all of those within the list box? I need to get the number and then make it a string. Once i have the number i can change this easily to a string

how to get the selected items from a check list box...i have 7 items in it, need to see which ones are selected...and how to clear the checks from the list box?
View 2 RepliesI've got a Checked List Box full of PC names that the user can check. I've also got a Combo Box that lists the location of the PCs - if the user chooses one of the locations in the Combo Box, it automatically selects all of the PCs in the Checked List Box that are at that location.
However, if that group of PCs are way down the list in the Checked List Box, you can't immediately see that they were checked.I'd like to know if there was a way to have the application automatically scroll/jump down to the area of the Checked List Box containing the PC's that were just checked.
Could not find this through Google or in SO questions.I have a checkbox listbox on my form. I want to filter my List by the list of selected Ids from that listbox that are checked, in SQL I would have done this like "Where TypeId In (1, 4, 5, 7)"... how do I do that in LINQ?
I feel like I am missing a really obvious answer, but cannot get it.
For argument sake... here is the what I have for sample data:
In Colors (List<of currentColors>)
ID, Name, TypeId
1, Red, 1
2, Blue, 1
3, Green, 2
4, Pink, 3
Selected Types 2 and 3 in CheckboxList: filteredColors

View 1 RepliesI seem to be having issues with the selected index on a list box.
The list box is having various items inserted depending on the user selection. An example would be:
LiIndex = ListBox1.Items.Count
ListBox1.Items.Insert(LiIndex, "Item1")
LiIndex = ListBox1.Items.Count
ListBox1.Items.Insert(LiIndex, "AND")
[CODE]......................
This all work and displays without a problem. The issue I have is if I select the second of the two AND's. If I click the second "AND" in the list and then a button to fire a method, the selected index is always the index of the first "AND". Dim listIndex as integer = ListBox1.SelectedIndex
I can't work out why, the listbox itself will always show the second one as selected, but the action will happen against the first one.

View 3 RepliesIn my Windows Form I have a ComboBox that is filled by a Stored Procedure with a list of names. I have the Combobox set for AutoComplete to "Suggest" and From "ListItems". When a user starts to type in and the AutoComplete does not find any matches in the listitems the user can tab out of the ComboBox and leave what they typed in the combobox even though it is not one of the Valid Items. Is there a way to check the Comboxbox to make sure of of the selected Items has been selected?
View 3 RepliesI'm looping all the properties in an object via reflection:
For Each p As PropertyInfo In values.[GetType]().GetProperties()
If p.CanRead Then

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?

Another 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.

I have an error panel that is subbed in to a page if an error goes wrong to gracefully handle and display errors.Currently, I am just appending the error messages to a string and pushing that to a label.

I have a List(Of MyObj), and I want to iterate through that list and compare each element to all other elements in the same list, excluding (if possible) the same element. I have a solution that works, but it's slow and uses double For loops. It may possibly have also summoned Cthulhu from his sleep. This below is a sanitized version of what I have:
Dim MyList As New List(Of MyObj)({Obj1, Obj2, Obj3, Obj4, Obj5, Obj6})
If MyList.Count > 0 Then
For i = 0 To (MyList.Count - 1) Step 1

I want to know how to test the 1st list box if it has items more than the other list box but by one item, here is what i have: If lstInvisibleTv. Items.Count > lstInvisiblePc.Items.Count Then it works good if the lstInvisibleTv list box is greater than the other list box by one but it also works if it is greater the other one by one or more which I do not want. I want it to work just by one.

highlight Fred from LB1 and Freddy from LB2, click and Fred becomes Freddy in LB1. I want this same change to happen but by selecting the "Fred" located in LB3 (If LB1 is hundreds of names long, I don't want to have to sift through it and only make the changes that need to be made). [code]

It would be nice if the checkedlistbox would throw an event when the spacebar is used to check and uncheck?
