Bad VkCode In Low Level Keyboard Hook?

Feb 26, 2009

I´m using the SetWindowsHookEx API to hook the keyboard, and it works, but when I get vkCode from the structKBDLLHOOKSTRUCT it gives me way too high numbers instead of the ASCII byte I expect to receive. Also, the numberchanges each time I press the same key, so obviously something is wrong. I´m on Windows XP 32 bits, VB 2008 Express, Net. Framework 3.5 SP2.

Textbox Hook Keyboard Events?

Jan 23, 2010

I'm using a textbox to define a hotkey, and I need to make the textbox receive key events and prevent the form from receiving them.The reason it's a problem is because Tab (and probably other keys) is a valid key, but the form uses that as a shortcut, so the textbox never receives the keypress.

How To Set Global Keyboard Hook On Separate Thread

Apr 29, 2012

After many searches i end up using this class for global keyboard hooking. Link: Global Hook post [code]My app is performing operations that take some seconds to complete (ftp upload small files on interval), and during this time the hook lovks the keyboard. This i dont want of course..I cant jump to Async FtpWebRequest right now because it needs many changes, so i thought that the solution would be to make the hoook live in another thread.A proposal is to move my time - consuming operations (upload) to another thread.Upon doing this i am facing other problems. Because the time consuming task (upload) is in a timer i would have to rewrite a big portion in order to synchronize the file->save with the file->upload and i dont mind the app locking for 3-4 secs. what i do mind is to loose the kayboard for 3-4 secs.

Keyboard Hook In Module Closes Immediately?

Apr 17, 2010

i am trying to make a app that loads a keyboardhook from a module on startup,
but unless i load the keyhook from the form the app just closes immediately.

i uploaded the keyhook module, to test it just start a new project, add the module,
to test it loading from the form just put hookkeyboard in the form load,

but what im tyring to do is have the module load first, so set the start up object to sub main

what this is suppose to do right now is just send a msgbox on every keystroke, it works from the form load but fails when loading from module, unless i am always typing something.

While the code effectively identifies if a key is pressed that matches a record in alMasterList, it does not block Excel from processing the keystroke. how I can prevent the key from passing to Excel?[code]...

Low-level Keyboard Hook Unhooks At High CPU Usage?

May 3, 2009

I have a program that uses low-level keyboard hooks, because it's a program that needs to be able to catch keystrokes, even when holding down capslock or what so ever.

Anyway, I figured out (by making a sample program running at the same time on purpose consuming 95% CPU by making an infinite loop with nothing in it) that low-level keyboard hooks stops working if the CPU usage is that high, and you do a lot of typing what so ever.

Keyboard Hook Module Closes Immediately If Set As Startup Object

Apr 17, 2010

i am trying to make a app that loads a keyboardhook from a module on startup, but the problem i am having is unless i load the keyhook from the form, the app just closes immediately.

what im trying to accomplish in the end is the module will will check a 'user settings' file, depending on the settings it will show a form or load the keyhook. but this is where my problem is, if i set the keyboardhook to load from the sub main in the module the app will just close immediately unless (as far as i can tell) i am always typing something

if i set it to load from the form it stays open, ive tried creating a second module and loading the keyhook from their but it still closes i uploaded a copy of the keyhook module if anyone want to test it / check out the code... all it does right now is pop up a msgbox on every keystoke, for testing purposes,

System Keyboard Global Hook - Prevent Any Other (local) Interception?

Feb 20, 2010

My final goal is that striking F12 prints the date (through SendKeys) in the application/window having currently the focus (Word, Excel, Outlook, whatever). I have consequently implemented a globak keyboard hook (system-wide), which is running well (source code below).

My concern is that I would like to prevent any other local treatment based on F12. For instance, striking F12 under Microsotft Word prints the date is the open document (which is fine!) but also launches the "Save as..." dialog box, since F12 is a local shortcut/keybinding under Word. (Actually, the date is printed within a field of a the "Save as..." dialog box). I want to avoid this.

In other words, my aim is to improve the "hook" below so that striking F12 does what I want (which is already the case) but nothing more. That is to say, I would like that, except my treatment, the system "forgets" that F12 was striken.

Option Explicit On

VS 2008 Keyboard Input To Text (in Keybord Hook-class)?

May 16, 2010

I'm using a barcode reader which emulates a keyboard with swedish layout. I'm using RegisterRawInputDevices to create a lowlevel hook, catching windows messages and checking which device that sent the keyboard input. If it's the barcodereader, I would like to store the input. I receive the key input one by one in this class - how do I translate this into a string? If the character to be sent is an #, then the keys sent are Shift+3.

.net - Mouse Hook In .NET And Windows Forms?

Nov 15, 2009

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!

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?

Determine When A Mouse Hook Has Handled Last Message?

Nov 16, 2009

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]...

Hook Into The Mouse Click On A Command Button?

Feb 24, 2011

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.

DIY Calculator : Keyboard Vs. Mouse?

Apr 30, 2010

I am creating a DIY calculator.The one in W7, I can't hardly see. Mine is much simpler and larger.I currently have buttons for numeric 0 - 9, Add, Subtract, Multiply, Divide, Clear, Enter, and Decimal Point.There is a label at the top with displays results.If I use my mouse to select the buttons, then everything works okay. However, if I use the keyboard, I get strange results.I thought it may have been my old keyboard so I changed it.No difference.If it's not in the hardware, then it's in the code.The section below is what I have for keyboard use:

Private Sub Form1_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles Me.KeyPress
Ch = e.KeyChar
Select Case Ch[code]....

For each of these, there is a corresponding Button_Click even farther down in the code. Since the mouse click on the buttons on the form works properly, the problem must be above. I can't see it.
