.net - MDI Child Form Does Not Activate When Clicked In Client Area?
Jul 29, 2010My VB.NET app supports several kinds of MDI child forms. Some kinds, but not others, are 'troublesome' -- they cause the focus mechanism to become weird. Once a 'troublesome' child form has been opened, NONE of the MDI child forms will become activated unless I click on either the title bar or the border. Clicking in the client area does not activate the child form -- its title bar remains gray, and it does not receive Activate or GotFocus events. Strangely, however, the clicked-on form actually DOES receive the focus, because its controls receive mouse and key events. Only the Z-Order and the highlighting do not change.
Once this problem develops, it persists even after the 'troublesome' form is closed, and it affects child forms which are opened afterward. However, if ALL of the child forms are closed, the problem clears up, and new child forms behave normally -- until the next 'troublesome' form appears.
I have no idea why one kind of child form is troublesome, and others are not.

View 5 RepliesSelecting A Specific Area Of A WebPage?
Oct 24, 2010I was wonder how, if you can, can I create a WebBrowser control or something similar to this, that will contain a selected area of information, and that information only. So it doesn't load and show the whole web page, only the part I choose.
For example, I would only want to show the weather portion of this webpage: [URL]
How can I get a specific area of a webpage, loaded into a form, that is able to be reloaded/refreshed later on?
VS 2008 - Autohide Panel Which Will Show When Mouse Enters Some Area
Oct 9, 2010I'm trying to make some autohide panels, which will show when mouse enters some area, and hide when mouse leaves the panel. This is however not so straight forward. I can handle MouseMove event for the form, to trigger "show" panel, and I can handle MouseEnter event for the form, to trigger "hide" when mouse leaves the panel. But this is not consistent, since sometimes mouse will leave the panel directly onto another control, and sometimes it will leave the panel directly "from" a control on the panel, and not from the panel itself.
Of course I could do the slow work and make logic for each control, but that is not very neat. Is it possible in some way to capture the mousemove event regardless of which control mouse is above?
Capturing Which Mouse Button Is Clicked On A NotifyIcon?
Dec 20, 2009I have a NotifyIcon (named TrayIcon). When I right-click it I get a menu. When I left-click it I want the form to be shown when it's minimized or hidden. But I can't find a way to get the latter done.
Private Sub TrayIcon_MouseClick(ByVal sender As Object, ByVal e As System.EventArgs) Handles TrayIcon.MouseClick
If e.Equals(MouseButtons.Left) Then
Me.Show()
End If
End Sub
When I debug, "e" shows "almost" same value ({X = 0 Y = 0 Button = Left{1048576}}) as"MouseButtons.Left" (Left{104875}) in the quick-watch window, still the Me.show is passed. I think this has to do with the X and Y, and "MouseButtos.Left" is of the type "System.Windows.Forms.MouseButtons" and "e" is of the type "System.EventArgs", but I have no idea how to get the right comparison.It's partially working though. When I leave out the if statement and only the Me.Show() is left, both right and left-click make the form pop-up. With the if statement, it never shows up.

C# - Determine Which Mouse Was Clicked (multiple Mice Devices) In .NET
Mar 20, 2010I want to detect when my touchpad is clicked! I normally use a usb mouse, so I don't use the touchpad for anything. Instead I'd like to make it possible to perform an action in .NET, when the touchpad is clicked. This way I can use it as a shortcut: One tap and something cool happens.
Is this possible, and if yes, any clue how? I'd prefer if it could be working in VB.NET or C#. My theory is that I'd have to make a mousehook, which then somehow determines which device the click is coming from. If the click is determined to be from the touchpad, then cancel the click and doWhatever().

View 4 RepliesVS 2010 - Program Checking The Colour At A Specific Coordinate - Switch Between Windows ?
Apr 16, 2011Basically what I want to do is create a program that every now and then (maybe 10 minutes) switches between either, all the windows currently open, or a selection of all the windows currently open, then checks the colour of a location on the screen. At the moment I have the program checking the colour at a specific coordinate, so that's all good. The problem I have now is how to switch between windows.
I've thought up a few ways to do this. The windows that I care about checking all have the same name, the same process class, but different process IDs. I already managed to stick all the process IDs into an array of integers hoping that I could use them but I don't have a clue how to bring a window to front using just the process ID. So the first method would work if I could figure out a way to do that.
My second idea, which is a pretty rubbish way of doing it, would be to simply simulate pressing Alt+Tab however many times to change between windows.
Mouse Movement In Specific Window?

VS 2010 Windows API For Detecting A Mouse Click Anywhere Or On A Specific Program
Jan 4, 2011I need to create a program that can run code each time the user clicks, I can't use windows forums since its on another program. If the code can detect global mouse clicks(system wide) or only on one program it's fine.
I've done some digging and it looks like windows API can solve my problem but i really suck at using windows API and it looks like SetWindowsHookEx() can solve my problem but i don't know how to use it correctly. This is the code from Pinvoke that I modified to hopefully work for a mouse click. i'm having trouble getting this to work.
