Listview With Checkboxes - Trap Mousemove Event?
May 19, 2009
I am using VS 2008. I have a listview control whitch 'checkboxes' property enabled.My question is: how can I trap a MouseMove event over an item only, excluding the associated checkbox?I have the following code in MouseMove event of the ListView control but it cannot differentiate between an 'item' and a 'checkbox:
Private Sub mylstview_MouseMove(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles mylstview.MouseMove
Dim oListViewItem As ListViewItem[code]....

I have this in my form:
Lots of ovalshapes... What I want to do is that when the mouse is over one of the shapes, it will display the name of the shape in a label. I can easily do it for each shape like this:
Private Sub p34_mouseover() Handles p34.MouseMove
Label1.Text = p34.Name
End Sub
[Code]....
But if I do it that way, I need to make like 120 subs. Is it possible to make one sub/function/whatever that handles this for every ovalshape?

Alright my goal is to test to see if the user has dragged a label over a button. I have add event handlers for MouseMove and ButtonEnter, the trick is that i dont want the buttonEnter sub to fire unless the user is actually dragging a label.Dim dragging As Boolean = False
[Code]...
I thought would work but because the user is dragging the label the mouse never actually enters the button field. I also tried doing lbl.location = button.location... but unless the label and the buttons are the exactly the same size in exactly the same location then the event wont trigger.

I'm writting program in VB 2010, but I have a problem. I want to draw a temporary line on PictureBox control MouseMove event. That works fine but deleting of that line doesn't work. I tried to draw the white line on the same coordinates (PictureBox's background is white), but won't work.
Here is the code: Private Sub drawing_MouseMove(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles drawing.MouseMove
[Code]...

Actually I'm creating a simple paint application in VB.Net 2010. I want to draw shapes in my application same as we do in Microsoft Paint using mouse.
I'm a bit successful also using mousedown and mouseup events of a picture box. The mousedown event sets the starting point and mouseup event sets the ending point(diagonally opposite point of rectangle.) The problem is "Nothing seems to be occuring between mousedown and mouseup events(Well..that is obvious because I didn't add any code on mousemove event). My question is: "Can I do something to see a growing rectangle during mousemove event?". The rest of the drawing should remain unaffected.

My program takes a checkboxed item and depending on the serial number that is present on the item on the invoice, subtracts one from the amount list I have the following in a listview on a details page which I added with the following code:
Item - Low Socks(pink)
Serial # - 34-75-860
Price - 5.89
Amount - 12
[Code]...
Right now it doesn't look like it does anything. I have tried changing my index's on my subitems to 1 and 3 instead of 0 and 2 but i figured because they are subitems that they need to be subitem index 0 and subitem index 2 since there is one item and three subitems to that one item.

I've got a listview with a bunch of items which all use checkboxes. Each time an item is checked or unchecked I want to save the selection. Whilst saving/loading the selection is not an issue, I can't seem to find an event which triggers AFTER the checked item has been changed. For example, the ItemChecked event will fire when an item has been checked or unchecked but the event will give it's checked status BEFORE it was changed. I've had to resort to saving the list when it loses focus but this isn't ideal.

This may sound like a silly question, but I can't seem to find an answer.Is there any way to "Check" a ListViewItem when the user selects it via property? I'm sure I can figure out how to do it in code, but I thought there was a property of the ListView. I looked through the documentation, Google, and in the properties panel, but I can't seem to figure it out

I have a problem setting the checked state of checkboxes in a listview programmatically.
Background: I have a Windows Form Application which uses CheckedListBox�s. The names/labels for each CheckBox in the list are imported for a database. Also in the database is a field which defines whether the CheckBox should be Checked or Unchecked. The program works fine.
Problem: My requirement is to add a tooltip to each item in the list of checkboxes. I have read that the best/easiest way to do this is to use a ListView instead of the CheckedListBox. I have setup a ListView with CheckBoxes = True and View = Details. I have populated the ListView with the items from my database. The ListView now looks exactly like the CheckedListBox and the tooltips work fine.
My problem is that I can�t seem to find a way of setting the CheckBox�s to Checked programmatically. Is there a way to do this, or is there a better way of achieving what I am trying to do?

I've got this code which basically loops through a set of folders and subfolders and finds specific file types. And then lists these in a listview. Now, it's intended to list exe and msi files. And I've made it so that these icons can be doubleclicked after they have been listed. I do this by adding the path to the file in it's tag property.
But, my superiors want a checkbox next to each item. So that they can check each item they want installed. And then have a button which runs the path in each tag property one at a time. It's basically the part where I fill the listview with the checkbox, filename of the exe or msi file, tag and the icon that I'm wondering about.
This is the existing code. This includes just a Tile view of the listview. Public Sub getDirectories(ByVal strFilepath As String, ByVal strFileExtension As String, ByVal objControl As Object)
'Load first files from the root folder. Then loop each subfolder
Dim di As New DirectoryInfo(strFilepath)
Dim aryFi As IO.FileInfo() = di.GetFiles(strFileExtension, SearchOption.AllDirectories)
[Code]...
But there should be a way of combining these two right? I'm not sure how I can add a checkbox in the first column of the listview? I've already set the Checkbox property of the listview to True. But I could use some pointers here if anyone's got any. :)

I have a ListView with the columns 'Name', 'Expected', 'Total', and I want to add another column saying 'Recount' at the end. The 'Recount' column will ideally have a checkbox only if the 'Expected' value is larger than the 'Total' value.
So far I have got the ListView with columns and can add a check box on the left hand side, but that check box is not under a column heading (though I can probably put another column with no values in there to work around that) and it is on all of the records.

I have a VB.Net Winform showing checkboxes inside the ListView which works fine. I want to know how to make the checkbox work like the RadioButton. ie. I should allow the user to click only one checkbox on the listview. If there are 2 checkboxes in 2 rows and then when the 2nd checkbox is checked, the first checkbox "Checked" should be cleared. When the 2nd checkbox is clicked the 1st checkbox "check" to be cleared.

I'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.

I have a tree view with checkboxes. When a user checks an item in the tree, all items below it in the tree should be checked automatically to match the parent. The same is true is a user unchecks an item. That's been reasonably easy to implement using the after check event:-
Private Sub tvwUserGroups_AfterCheck(ByVal sender As Object, ByVal e As System.Windows.Forms.TreeViewEventArgs) Handles tvwUserGroups.AfterCheck
If Not m_Isloading _

I am rotating a picture dependant on the mousemove.
Private Sub PictureBox1_MouseMove(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles PictureBox1.MouseMove
[code]...
To simplify the part I am having problems with: rotationX = CurrentPositionX + ((InitialPositionX - MousePositonX) / SlowDownDivisor)
As an example, this occurs in both X and Y; If I click and drag in the X + Direction and release the mouse button it does exactly what I want, rotation in the positive direction. If I click and drag in the X + Direction and then drag in the X - direction, the rotation continues to be positive, it doesn't reverse. If I release the button and then click again and move in the X - direction the rotation is negative as it should, but it will continue to rotate in the negitive direction until the button is release.
