I would like to fire an event when double clicking on a listview, but more specifiquelly in the blanck area (where NO item exists)I have read from this msdn page :
Quote: The mouse pointer must be over a child object (TreeNode or ListViewItem). how to fire the event another way ?
I am trying to learn Visual Basic and am working through a text book that my son used for a class. Each time I create an event handler by double clicking on the design page, the code that automatically populates is almost identical to the code in the book, except the byval portion is omitted from the code.[code]
View 2 RepliesI have a login page, which a user will have to enter username, password and accesslevel. Accesslevel is either 1 or 2. 1 for admin and 2 for users who are restricted from using certain functions. I have this module set up so that I can make use of the accesslevel throughout the forms that I have.
Module ModuleAccessLevel
Public AccessLevel As Integer
End Module
Arjun taught me how to make use of this module, so now I know how to restrict users from using certain buttons, toolstrips by doing the following:

Does anyone have a trick to catch when the mouse is over a listview column header ? As you know there is no native handler that would fire such event...
I have build a small routine that will be able to tell over which column the mouse actually is, the problem remains in which event to put it..
After inserting an user control and double clicking on it, a stub with the default event should appear.
If I don't define what the default event is and I don't assign any attributes to any events or properties, it works, and it generates the stub for the UserControl.Load event (the default default event).
But if I set some attributes for the properties and events and/or I define the default event, the stub generated is corrupted. Here is an example of what I should get:
Private Sub FaceSelector_OnSelect(SelectedObjects As System.Collections.ObjectModel.Collection(Of Object)) Handles FaceSelector.OnSelect
End Sub
And this is what I actually get: Private Sub SketchSelector_OnSelect( SelectedObjects As System.Collections.ObjectModel.Collection`1)
End Sub
Private Sub FaceSelector_OnSelect( SelectedObjects As System.Collections.ObjectModel.Collection`1)
End Sub
In this case I had 5 user controls, I double clicked on one of them, and I got 2 corrupted stubs.
Sometimes the corrupted stubs are generated when I change some properties of other controls in the form, or the form itself. For example I resize the form, the error window doesn't show any errors, hit F5 to compile and run, and get a syntax error.
I tried to track the problem down by removing each event/property attribute/xml description, one by one, many times I thought I found the culprit, but after 10 minutes the problem popped up again.
When I double click on a form control while in the design view in a Web Application project within Visual Studio 2010, say a 'button' or a 'submit' for example, it inserts a javascript function into my .aspx file. When I do this at work it automatically creates an event handler for the control in the code-behind.How do I change this to that setting?I don't want to type those event handler subroutines every time!

I'm trying to finish up Visual Basic project for a class to create a playlist of files and to have them played.I have everything working if I single click the item from my list, and then click the play button in the WMP control portion of my form.I then want to add the functionality of double clicking the selection in the list and play with the following code:
[code]...
and nothing seems to happen.Digging into values of the debugger at the time I try to play the file:
[code]...
The sourceURL of the first item in the playlist is correct, but the duration is 0:00 (it should be 0:01). Since it seems there is no duration detected, nothing is played. Any idea what I missed? Again, if I single click the file, which sets the playlist as I want, then click PLAY on the GUI controls, it works fine.Also, is there any way for the program to detect when the song has changed when playing a playlist of multiple songs? I want to have label fields showing "Now Playing" information that would change info as the songs change, and maybe even change the item selected as things are played. I've not yet found a way to detect this change, only when the player starts and stops in general.
I am using Visual Studio 2008 and VB.NET. I've got a listview control on my form and I've added columns using the windows forms designer. As you know, if you double-click on the sizer or divider or whatever you want to call it between two columns, the column on the left will autosize (unless you disable that). How can I catch this specific event? The ColumnWidthChanged event and the DoubleClick event are likely candidates, but in the ColumnWidthChanged event, there's no way I can see to determine if it was an autosize. Similarly, there's no simple way to catch what was clicked exactly with the DoubleClick event. how I can catch this specific event type?
View 1 RepliesSomeone asked me to add a function when the notifyicon is doublcliked. I figured that'd be easy with the mousedoubleclick event being available. I find out that then both the single and double will then be called. Well that sucks, I want it to only do the one the user requests. So I tried to get it to work:
Private Sub DblClick_Tick(ByVal sender As Object, ByVal e As System.EventArgs) Handles DblClick.Tick

View 1 Replieshow to get the DataGridView CellMouseDoubleClick to fire when a user double clicks on a DGV cell.I currently have both DGV.CellMouseClick & DGV.CellMouseDoubleClick implimented in my code.The DGV.CellMouseDoubleClick never fires and the DGV.CellMouseClick always fires. The only exception is when I position the cursor between DGV cells and get the double arrow. If I double click with the double arrow then I get the DGV.CellMouseDoubleClick to fire.I need to take different actions for users RT-Click, RT-Dbl-Click, LT-Click and LT-Dbl-Click.
View 5 RepliesI have added a handler in my code for the bindingsource currentchanged event: I have populated a datagridview. AddHandler PeopleBindingSource.CurrentChanged, AddressOf ChangeHandler then on the ChangeHandler Sub I populate an HTML report. However I don't think this is the best event to handle this. I have to datepickers on my forma as well. So say I click on a row in my dgv, that persons report loads. Then I change the start date on my datepicker,
Now i want to click on that row again to refresh the data, but since the currentchanged event doesn't fire the data won't refresh. I have to click on another row then click on the row I want to view in order for the event to fire. which event is best to do this?
I am getting very frustrated with how this was set up. When you are trying to navigate and move things on your form and accidentally double-click, it adds a sub procedure On-Click to the form, then you have to waste time and delete that segment and get back to your workspace.Does anyone know is there an option in the UI options somewhere to change this, so that when you double click it doesn't perform that way? I would like to set it to CTRL-Double click if possible, it would make the program a lot more user friendly for m
