Removing Items On Double Click From ListBox
May 24, 2011
I have to make a listbox with a few(8) names in it & double clicking on a name in the listbox will removed the name from it. I have already add the names into the form using the listbox.items.add method & would display the names in it. Then I enter the coding for 8 names in double_click procedure (listbox) using the "listbox.items.remove" method. However, when I try double clicking on a name in the listbox, it would remove all the names instead.

I have a situation where I am handling both single & double mouse click events on a form. In both cases something has to be loaded, however when a double click occurs, I do not wish to execute the code attached to the single click event.Is there a way to intercept the mouse click's and check if double or single and then execute the right event appropriately?

Im working on a school project where i add items to a listbox in two columns. The first being the name of a course and the second being the credit hours of the course. I can add and remove the items just fine BUT when i remove an item im also required to subtract the credit hours of said item from a variable i have called "totalhours." Essentially im trying to figure out how to subtract a certain piece of a selected listbox item from my class level variable.

I got this code but it won't work...
For Each item In ListBox1.Items
For i As Integer = 0 To ListView1.Items.Count - 1
If item.ToString = ListView1.Items(i).Text And ListView1.Items(i).SubItems(1).Text = TextBox4.Text Then
[code]....
It only deletes 1 listbox item while there are more items that have to be deleted.after debugging i get this:List that this enumerator is bound to has been modified. An enumerator can only be used if the list does not change.

I want to remove items from a listbox 1 at a time. I have two timers set up to remove the two types of items that are put into the list box. When there is a "Player 1 killed Button 1" following a "Player 1 killed Button 2" or vise-versa they get removed at the same time. Is there any way to prevent this?
Code:
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim XP As Integer

I need to know if there is a way to remove any items from a listbox if they contain no text. Like if there are three items(Blah, ,Blah) listed in the listbox like so (remove the middle line that is empty so the listbox now contains two items(Blah, Blah) listed like so Or if there is a way to do this to a textbox that would work too. I'm working in VB 2010

How would I remove an item from the listbox.. I used the code below to populate using a class with description and value properties.
I cant use listbox.items.indexOf("listitem1") to get index
I cant use listbox.items.remove("listitem1")
If I use listitem.items.removeAt(1) it works of course. How can I get my index in this case?
'Users
Dim IAdapter2 As New ds_SecurityTableAdapters.Security_UsersTableAdapter
Dim usersDT As ds_Security.Security_UsersDataTable = Nothing
usersDT = IAdapter2.GetUsers()
Dim userItems As New List(Of myItem)

On my form is a listbox whose items - when clicked - will execute a separate vbscript file (for WMI) and display the results from the WMI in a multiline TextBox that's read from a text file.
My problem is that I have to click an item in the ListBox twice to view the WMI results in the textbox. It's like 1 click executes the vbscript, another click writes the results to the textbox. A third click does both.
All the activity (retrieval of the target computer, creation/modification of text file, execution of the vbscript and writes to the TextBox) happen in the SelectedIndexChanged event handler.

I have written an application using VB 2005 Express. It's a very simple application. There are basically two listboxes, one to the left and the other one to the right of the GUI.Listbox1 contains a list of names. When you double-click each name, a code word is created and added to the listbox on the right. Now... here is what I want to do. I would like to automate the double-clicking process with the click of a button so that each name on listbox1 is double-clicked in sequence

I am using VB.NET (version 2008). I have two types of items populating in a listbox (checked listbox). For example: lets say one is type "A" and other is "Type B". Their names maybe same so if the user sees those items in listbox then he won;t be able to determine their type until he click on them and checks out its properties. I wanted that I add each item to listbox and colour them so that blue for example means type "A" is there and red means the other. So this way I will be able to know at a glance that how many item of what type is present. I guess it may not be possible to do that in a standard checkedlistbox. I am also using component factory's krypton controls which enhance the gui of an application. But I dunno if I can progress using that.

I am having a similar issue with the double buffered set to true for a picturebox. I customized a picturebox control in vb.net where, a panel contains the picturebox.
Upon a mousedoubleclick of the picturebox, i scale the picturebox width wise a certain scalefactor, so that the picturebox is greater than the size of the panel. I am doing this for horizontal zooming and panning. With that said, the picturebox could become large in size.
At certain screensizes, after scaling the picturebox 6 times the size of panel, at fullscreen, i receive an error messsage implying "Not enough memory available to process the command."
However, when i turn off double buffered, i dont get the error, but i get much unwanted flickering.
Here is my code in the Paint Event:
Private Sub picPMGraph_Paint(ByVal sender As Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles picPMGraph.Paint
Dim i As Integer

I have a vb.net application that uses Flash movies (AxShockwaveFlashObjects.AxShockwaveFlash). I have buttons in the flash movie. When they first start using the application, they can single click on the buttons in the flash movie and button responds accordingly. But after a while (and I haven't been able to pin-point an exact thing that changes it or my issue would be solved), the user has to double-click on the button in the flash movie for them to work.

I have a grid that displays data from a binding source. I have a method to handle the CellContentDoubleClick which will get the value of the cell and use that to do a new look up. This will generate a new datasource (with different columns) which I then rebind to the grid.
My grid double click works, but when it repaints with the new data, a single click fires the double click. I have no code in place to handle a single click .
The interesting thing is that it is (in my case) a toggle. If I double click, on the repaint, a single click fires the double click code. When it repaints again, I need a double click .
The double click code fires off a messagebox - if I tell it not to continue, then I have to double click to get it to fire again. So it is not dependant on what data is displayed.

When it is in the mode to respond to a single click, I can tab through all the controls and then click on any cell in the grid and it will still fire the double click.
No matter what I try to do (set focus to other controls, refresh the grid, etc.) nothing seems to reset the grid so it works consistently.

I am trying to search through listview in VB.net 2008. It works fine with small list, but when the list is big ( around 25000 rows), if I search multiple items , it fails saying that index is not valid. Obviously what I understand is , it it tryiong to remove an index does not exist. But I am unable to figure out where exactly it is going wrong.
PS : while it is doing search through the entire listview, I am incrementing index = index+5 becasue I want the next 5 rows to be in the selection state as well.This is the code Private Sub TextBox1_KeyUp(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles TextBox1.KeyUp If (e.KeyCode = Keys.PageDown) Then
