Hook Mouse For All Apps / Desktop?
Sep 16, 2010
Using VB 2010, is it possible to capture all mouse clicks and determine what was clicked?We're trying to develop a small utility that will pop up context based menus to fill in application forms and common strings for terminal sessions.Basically, whenever I middle click I want my app to determine if the window was an occurance of PuTTY. If so, check the titlebar for certain strings and send keystrokes to that window based on the titlebar text.If VB 2010 can't do this, what should I be looking for? Will VB6 apps do the job? Will they work on a Windows 7 PC?

I have a form that is displayed, not by ShowDialog, but by setting its visible property to true. This is so it behaves like a dropdown.The form installs a mouse hook, using SetWindowsHookEx(WH_MOUSE, ...).
I detect if the mouse is clicked outside of the dropdown and if so, return 1 in my HookProc method and close the dropdown.The strange thing is, if I click outside of my drop down on to a textbox, the textbox still receives the mouse click, after my dropdown closes, even though it's been handled by my HookProc method.It gets stranger... If I click on a label or button, they do not receive the mouse click, as expected, after the drop down closes!

Ok, I know you can import system.web.security in asp.net applications, but i was looking for the dll in the .net and comm listings and it isn't there. Can you not use the Membership.createuser() etc in desktop apps?
If not, what is a good alternative for quality security and roles control?

I have a form, that acts like a drop-down, that I display non-modal. I attach a mouse hook to the form to determine when the mouse is clicked out of it, so that I know to close it - by setting Visible = False.
Because I want the HookProc to handle the last click, I can't dispose the Hook or my Dropdown until I'm sure that my event handler has returned to the HookProc.[code]...

I need to write an application that can validate wether or not a proper process was followed based on information that was entered into another .NET appliction. Basically, I need to be able to intercept a mouse click on a button in another application so that instead of submitting the data it triggers my validation code then cancel the action if need be.
We do not have the code to the other application. I have everything I need perform the validation. The only thing I don't know how to do is intercept the mouse click on the button control of the other application. Can some one show me how this is done?

I'm using code from here - [URL]. And I'm getting the old
A call to PInvoke function 'EliteSwitch!EliteSwitch.MouseHook::CallNextHookEx' has unbalanced the stack. This is likely because the managed PInvoke signature does not match the unmanaged target signature. Check that the calling convention and parameters of the PInvoke signature match the target unmanaged signature.
Error on this line
Return CallNextHookEx(MouseHook, nCode, wParam, lParam)
I've tried changing variable types but I can't get it.

I'm attempting to intercept and interrupt mouse events. Lets say I wanted to disable the right mouse button down event, or even the mouse move event. I haven't been able to figure out the interrupting part.
I am using the (I assume pretty widely used) following code for Global Hooking of the mouse.

I am a newbie to this forum. I searched across a lot to find a way in VB.net how to capture the keyboard and mouse events scoping to the whole computer. Basically what I want to do is make a keyboard and mouse macro recorder application, so that the regular job of starting the same programs again and again everyday might be automated.

what WPF based apps are?Is it an application that runs under Silverlight? If so, how?I know; Windows Forms based apps,console apps,DLL _ Class Library Projectsand I've had an introduction to ASP.Net.What I mostly want to know is, if WPF apps are for Silverlight then do they also run in a server based fashion like anASP.NET website would when you create ASP.Net webpages?Is it a way of creating what looks like a FORMS BASED application but it runs in a browser instead or what?Please enlighten me a bit further as I have no idea what WPF is all about.

I have two custom action listers. One that handles Mouse.Click and one that handles Mouse.MouseDown. My question to you is, can I delay the mouse down event so that it does not intefere with the code of the Mouse.Click event? I have tried adding a timer and waiting x amount then setting a bool value to true, but the code executes to fast and it skips the other code.

Some of u already know I'm making a 'virtual desktop'- thing.Only one problem. When switching to a new desktop it starts a new instance of my app in that desktop (works) and on the form load event it says process.start("explorer.exe") <- here is the problem. It only shows a window not the actually bar.Also this may be important it shows the window, but when I navigate to explorer.exe 'C:Windowsexplorer.exe' and open it there. The explorer bar does show up.

I'm working on one of my applications and I'm trying to find a way to use the "Go To Desktop" function that goes directly to the desktop without minimizing any window (This can be achieved by clicking on the Win + D buttons or on the desktop icon in the quick launch toolbar), but how can I activate it using vb? I thought about sending keys but I guess there is more offical ways to do it.

Is there any way I can install a global hook or something else on the start of external process. WH_CBT hook, as it appears can only intercept events for processes that have windows, but what if I want to intercept the start/stop of a windowless application or a windows service? Is there any way to do it using .NET?Generally, I want my application to receive a notification of some process being launched knowing only an executable name.Presently I simply use a timer to iterate through running processes, but I wonder if there a better way to do it?

url...This example works on a my 32 bit XP machine, but it does not work on my Vista Ultimate 64 bit machine. The example is supposed to hook notepad so that whenever I type a character in notepad, a text box recieves the same character. This works on XP, but on Vista 64, nothing happens.I should probably say that when I first ported the example to Vista, I ran into 2 problems, which I think I correctly fixed.
1. I was getting a BadImageFormatException when the DLL was first trying to be accessed. I fixed this by setting the target platform in the VB project to be x86.
2. I was getting a DllNotFoundExeception, so I placed the "MainHook.dll" file in both:[code]I have a couple of theories, but I'm a bit of a beginner when it comes to hooking. Could this be happening because Notepad is a 64 bit application and the hook is written in 32 bit? I have the express version of VC++, so I can't create a dll targetted to 64 bit, so I haven't tried that.
