Double Clicking In VB?
Sep 2, 2009
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

Someone 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
[Code]...

I have been scratching my head for a while on this, but not sure if it can even be done. Basically I tried the listbox_doubleclick event but that did not suffice. I am looking for something to use that can run my code when an item in the list is double clicked.It works with the listbox_doubleclick as should, but the problem with this is if I double click the listbox anywhere, it will run the code for the selected item.

i have been working on an app, that remains just my preset sizes. recently, i have discovered that by double clicking the form title bar, even w/the formborderstyle being set to fixedtoolwindow, the form still maximizes and all of my controls remain in the top/left corner.. not a good view.. so, i set the maximum size of the form, and now when double clicking it, moves it to the top/left of my desktop.. not a good result. here is a quick sample to start w/.
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
[Code]....
how do i permanently block the double click on the title bar, to have no effect on the form? i do not want to end up w/having to create a borderless form just to avoid this..

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.

How is it possible to open files (*.lva) made with my application by doubleclicking on them, as I can open MS Word etc files.My files are saved using StreamWriter member WriteLine.When I doubleclick on file made with my application, it has to fill some textboxes.I can open files through my application using ReadLine command, but not doubleclicking on them.I use Inno Setup Compiler to install my program and I'd like to associate *.lva files to open with my application.

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]

I didn't get the result I want from the following code:
Private Sub tblView_SelectionChanged(ByVal sender As System.oject, ByVal e as System.EventArgs)Handles tblView.SelectionChanged
Dim st As String = tblView.SelectedRows.ToString
[Code]....
I wanted the data I selected on the datagridview row to be display in the textbox, but it displays the error message that st(0) produces "S" which is incompatible to my RackID data type.

I 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:

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.

I have an ArgumentException was unhandled message: Cannot add or insert the item '1' in more than one place. You must first remove it from its current location or close it. Parameter name item. Note: Have 2 listboxes 4 textboxes double click listbox2 and it fills in the four texboxes (now it needs to put it back into listbox2 in the same place it came from but crashes. I marked the area and underlined where the error message was coming up. So double click a selection in listview2 (fills 4 textboxes) then double click textbox2 (should return text data back to listview2 in same spot) but crashes. See code below.

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!

The title pretty much precisely asks the question, but I shall repeat;

When the user clicks the Exit button it closes the forms and if there was an open file it asks the user is they would like to save. But after the application closes there is still memory being held in Processes by the application. However, when pressing the [X] in the top of the form the application closes again but in this instance it is not held in Processes. How do I write the close for Exit to take into account how the [X] works and close the application cleanly?
Friend Sub CloseAllForms()
CloseHelpForm(True)
CloseDiagForm()[code].....

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?

I have a htpc project that I am working on. The main program loads dll plugins which are basically other win forms. On each of these forms, including the main program, I use a picturebox (a double buffered picturebox) for the background image and then draw everything on it by hand. Whenever I load the form from the dll and show it, I get a weird flicker. It looks like it is the previously used double buffer. Is there any way to clear the background double buffer before the flicker? Or am I going in the wrong direction?
Here's a couple of videos of the problem:

For greater accuracy I should use a Decimal instead of a Double ( so I've been told ). Why then have Microsoft chosen to use DOUBLE for most of the functions that return a floating point value in the Math Class?

I've asked this question before, and so have many before me, i have done extensive research on the topic and stil no help. Maybe this is some kind of secret info. shared only amongst top programmers. Bt how do you really, trully double buffer a form, aside from setting "Double Bufferd" to true, which doesn't work in most cases, I want to know how do companies lyk Microsoft and Symantec, prevent flashes on big applications such Word and Norton.

If I try to display a command line argument that has double quotes around, the double quotes are always stripped off. How can I avoid this?
for example, the argument is "c:xx.txt" and this displays c:xx.txt instead Console.WriteLine((My.Application.CommandLineArgs(4)))
