VS 2010 - Global Key Hook Not Working?
Jul 3, 2010
I have a program that u record your clicks then you press a button (Ctrl + E) then it plays them back. What I want is for Ctrl+E to stop them, It would work but it seems like its being overpowered by the mousemoving and clicking. The keyhook did already work before I started on the playback part.
Protected Overrides Sub WndProc(ByRef m As System.Windows.Forms.Message)
If m.Msg = WM_HOTKEY Then
If m.WParam = 2 Then
If started2 = True Then
started2 = False
ElseIf started2 = False Then

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.

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.

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 have implemented a global Hotkey into my code but the problem is that when I move the focus from the form to IE (For Example) i cannot use the Hotkey from my application. Everything is working great if I was to stay int the form but that's not the purpose of this code.
Private Sub frmMain_Load(ByVal sender As System.Object, e As System.EventArgs) Handles MyBase.Load
RegisterHotKey(Me.Handle, 9, MOD_ALT, VK_F9)

I have several windows open: VB, IE, Explorer... If I happen to close one accidentally, or on purpose, and reopen it, the buttons on the task bar are all messed up. I get used to them one way and I am constantly switching between the windows.Here is my question: Would I be able, in VB, to 'hook' the taskbar and be able to rearrange the buttons?I have no idea what to search for in Google. I happened upon a program once a while back, A REAL LIFE SAVER!. I could just click and drag the buttons using that one.

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.

To be honest I am fairly new at VB as a language, and I just came across a problem that I can't figure out. I have a feeling it's something simple...but here it goes.I created a set of string variable on my first form as follows:
Dim strpro1 As String = txtpro1.Text
Dim strpro2 As String = txtpro2.Text
Dim strpro3 As String = txtpro3.Text
Dim strpro4 As String = txtpro4.Text
Dim strpro5 As String = txtpro5.Text
I set strpro1 as a global variable in my module:Module Module1 Public strpro1

I have an application which is strictly numeric input only, for everything in the main form, call it X in this post.
I want every single control that can handle input in X to only accept numeric entries, I have a way of doing this but it requires me to put a tonne of arguments for the handle, I tried to change this to handle any .KeyPress event on MyBase or Me (X) but it won't work.
Code that works but requires 1 000 arguments:
Private Sub numeric_keys_only(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles msTEXT.KeyPress, ssText.KeyPress etc...
[Code]...
I have tinkered with the latter, specifying things like all the controls in a certain group box and it doesn't work.
I know the sub header has to be changed - I have changed it in my tests, that is just the example code. When I change everything it runs, just doesn't do anything.

I have an array of comboboxes on a form. They are declared at the beginning. I wish to make these global variables so I can access them in another form. This does not appear to work.
Code something like this:
Public Class SecondScreen
Public OutputSelectControl() As Combobox = {O1, O2, O3, O4}
Where O1 O2 etc are the names of my comboboxes on this form. I wish to be able to address them from another form like so
localformvariablehere = OutputSelectControl(integervariablehere).Index

I was a VB6 programmer. And back in the day global variables, functions and subroutines were put in a module. The program started in the module using a sub named Main(). Now in vb2010 it looks like using sub Main() is possible only for console apps, which is not what I want, I'm still trying to write a windows app but it looks like everything has to go at the top of the starting form?? How is this good coding practice? Shouldn't public vars and functions be in their own module?What is considered best practice?Are there any links that would walk me through the differences between vb6 and vb2010?

I've got a multi-threaded app - that is using a global COLLECTION of objects.I'm starting to think that objects - when copied to objects - are really just reference pointers to the "single object" in memory - as they would be in JAVASCRIPT (too many languages At any rate - this code - when taking the object from the collection to work with is it making a new object to play with or is it working the single object that actually resides in the collection?
