Hi,

I'm planning to make a program that monitors the mouse events, each time the mousedown event occured, it has to return the name of the buttom which the click event has occurd on it(the buttom that is pressed).

I have no idea how to that.
Any ideas about doing it would be absolutely useful.

thanks in advance.

What I have tried:

Right know I'm reading about mouse events on msdn.

You can use MouseDown event of the controls to identify them

Let's say it's a module that is being added to a program which already has about 1000 buttons.

Each Event gives you the Sender (as object). The Sender is the control which raised the Event.

I think I got your point.
Can you give me more information.
Thanks.

Ralf Meier 12-Jul-16 3:40am

So ... each of those Buttons should refer to the same Method with the Event you want to have.
This could be done with a Loop.
To give you a solution I you should give me more Information ...

What programming language do you use ? C# or VB ?

m.r.m.40 12-Jul-16 3:46am

I'm using VB.
My own idea is to create a thread which is always monitoring the mouse event, so each time the mouseDown event occures, it gets the required datas.
Thanks.

You can trap all windows messages in you application using Implements IMessageFilter, this will not tell you what was clicked just a click occurred somewhere on your form, you could then use me.ActiveControl to determine what was clicked but you'd need to know control names to determine if it was an event you wanted.

As Ralf says you can add code or call a sub passing the control name as argument that does whatever you want to do with the event.

A button logically requires a click event handler you can do what you like in that event, if you add a module to an existing 1000 button project (pity the user) write a sub to do what you want and add a call to that sub in each event handler for the 1000 buttons.

Well, It's a great idea,
The following line of code helped me,

MessageBox.Show(Me.Name.ToString() + " >>> " + Me.ActiveControl.Name.ToString())

Now I'm having another problem, how to dynamicly add this line of code to all click events of all controllers.

If you don't understand event handling well enough, you should not attempt to do such application-wide stuff. It does not make much sense to show the name of each button in a message box as it would affect the usability of the application.

Adding that to all form or user control can have some side effect on your application and might be a bit harder than you might expect as you might need to ensure that you also remove the handler at the appropriate time and there might also be some buttons you might want to ignore or some other controls should be considered as buttons (toolbar buttons, maybe hyperlinks...)

If you are constructing a WinForm app, and want some thread updated by user actions in the UI, that will not work.

The idea of a UI with one-thousand buttons is so unlikely as to approach fantasy. Why don't you tell us what you are trying to achieve ... the big picture.

m.r.m.40 12-Jul-16 6:23am

I'm asking for ideas here,
The picture is as follows,
Lets say I have a software system already developed including 20 subsystems totally includes 1000 different functionality(the 1000 buttoms). now i'm going to keep track of the user while working with this software system.

Ralf Meier 12-Jul-16 6:48am

Sorry ... I don't understand your "big picture".
Would you please try to explain that with a Screenshot ...?

See if you can open or read the following question link:

Thank you very much for helping.

Start by doing some research into 'GlobalHook; there are several articles on CP about how to create one. You can have an application-scope global hook, or a windows-os-scope global hook.

You could have your run-time app ... every time it creates a new Form ... recursively parse all the Controls and add a Click EventHandler to every Button.

Is your application a WinForm application ?

m.r.m.40 16-Jul-16 1:42am

Yes it's an WinForm application. sorry I answered you very late.

If I understood well what you meant you could (for example) do it like this :

First you create a Module which has the code for the Button-Click-Handler :

VB

Module TestModul

    Public Sub ClickHandler(sender As Object, e As System.EventArgs)

        Dim mySender As Control = sender
        MessageBox.Show(mySender.Name + vbCrLf + mySender.Parent.Name)

    End Sub

End Module

Now, on each of your Forms you need to have the following script :

VB

Protected Overrides Sub OnVisibleChanged(e As System.EventArgs)
    MyBase.OnVisibleChanged(e)

    If Me.Visible Then ' create Handler to each Button when Form is shown (becomes visible)
          For Each myControl As Control In Me.Controls
            If myControl.GetType Is GetType(Button) Then
                AddHandler myControl.Click, AddressOf TestModul.ClickHandler
            End If
        Next
    Else ' remove Handler from each Button when Form is left (becomes unvisible)
            For Each myControl As Control In Me.Controls
            If myControl.GetType Is GetType(Button) Then
                RemoveHandler myControl.Click, AddressOf TestModul.ClickHandler
            End If
        Next
    End If

End Sub

Of course severall other solutions are possible.
Also it could be a good idea to build a baseform which has this method and all forms in your project derive from this baseform. In this case they automaticly get this function.

The Handler-Method in TestModul will do what you want to be done ...
