If my window is hidden or out of focus, how do I detect a keypress? The idea is that it just sits in the tray as an icon until a key combination is pressed and then it pops back up again.

How do I detect a ctrl+tab keypress?
Reason for asking: I want to stop a user from changing tabs in a tab control.
I want to be able to detect when the user presses F10 or Ctrl+F10 outside of my program, and upon receiving the key press, it will send text to whatever they currently have selected (e.g. a text box). How can this be accomplished in the simplest way?

View 1 RepliesI am creating an application that creates scripts to move a mouse and to click where a user wishes to via pre-programmed code and to also press keys where required. I have the code to move a mouse and to manually click anywhere. What I am after is to detect when a mouse button is pressed and dragged and when keys are pressed.
I see that there is the following
MouseButtons.ToString
To detect when a mouse button is pressed, and have it looping in a timer. Is there a better way to do this? I would rather not use a timer. And is there a similar routine to detect which keys are pressed?
I'm trying to detect the Printscreen keypress with the use of a timer. I can't useform1_keyup/down as the focus isn't always on the form.
View 4 RepliesI have two issues. The first is that I want to make a textbox scrolling similar to how credits scroll. I don't want it to move on the form, just to scrolling the text down a line/pixel. I thought I could do it with the "Lines" element, but I'm not exactly sure how to execute it.
The other problem is with my flash screen. Right now I have it set so when a button is click, it goes onto the main form. I don't want to use the button but rather have it so if Enter is pressed at any time, it'll go to the main form. All the solutions I've tried to use involve the "e.Keycode" code, but for some reason its unavailable.
I want to create a program that gets if the user has pressed a code, for example F8, but without the user having to have focus on the form. I want the program to start hidden, and while the user works normally (say browses the internet (Go Google Chrome)), he just presses F8 and the form shows up. So I ask, is there any way to get key presses outside the form? [code]
View 2 RepliesI want to detect if a user has alt-tabbed to an other application, so that I can auto pause my application, or let my application blink in the taskbar. Problem is that I can't figure out when someone has alt tabbed to an other application or has clicked an other application.
View 1 RepliesHere is what I've done:1) Created an Excel COM add-in for Excel 20032) Added a NotifyIcon to the Windows taskbar notification area (aka system tray) during ThisAddIn_Startup3) Added a ContextMenuStrip with a ToolStripButton to the NotifyIconWhy is it when I right click on the NotifyIcon, Excel gains focus? If after clicking on the NotifyIcon to display the ContextMenuStrip I choose not select an option on the ContextMenuStrip and instead click back on the Excel window, I get a weird flashing cell in Excel.I've created a video of the problem to help you see what I [url] anyone know how to prevent this? Ideally, I'd like to be able to click back on Excel and only have the ContextMenuStrip close and Excel regain focus.

Do
If e.KeyCode = Keys.F4 Then
Exit Sub
Else

My problem here is that what the loop does is click on another program, thus taking the focus off of mine, how would i be able to make my app see if I press the key even if the form isn't in focus?
I want to make an auto log off feature, I want to detect if there is any user input, and if there isn't the user will be automatically logged off. So I want to know how to detect mouse wheel events when the form doesn't have focus.

ok when my program is running from scratch I have a piece of code that just says if the size is this.. then make this.. else make this.. so it just makes is small and big..after you close it.. it hides itself in the sys tray... if you bring back out of the system tray.. and click the button to make small or big.. does nothing.. it come out of the sys tray as the large size.. and wont go small again..
does something on the form get set when you hide it ? that needs to be unset to let it resize it ?

How can I detect the click event of the close (X) button at the top right corner of the control box of a form/window? Please note, I don't want to know about CloseReason, FormClosing, FormClosed or stuffs like these, unless they are inevitable. I exactly want to detect if the user clicked the X button of the form.

View 2 RepliesI have set the Visibility property of the main window to Hidden and added the following in Window_Loaded:

But it doesn't show up the Window.
I am using the code below, but it still shows the program.For example, if I pass in CALCIt will start the calculator but show it.

At the bottom of the Properties window in the Visual Basic 2010 IDE, there should be a brief description of the selected property. For example "Text: the text associated with thecontrol". But it's reduced to a height of 0 so far as I can tell, and I haven'tfound a way to make it visible. Right-clicking the Properties window and selecting/checking"Description" has no effect. How do I make this pane visible?

What command should I use to get focus on VB Form1 window? And what command should I use to get focus for another window? I need this so I can use send keys with no errors.
View 3 RepliesI am basically trying to list all visible (in taskbar) in a listbox and then, after clicking a button the selected process will catch focus (if it's not minimized). However, I have been using this code, and only seems to work on Notepad, on NOTHING else.
Imports System.Runtime.InteropServices
Public Class Form1
' This is 2 functions from user32.dll (1 for finding the application and 1 to set it to foreground with focus)

I have also used MANY alternative API's to test it on, it seems that after the line "ParenthWnd = ...." only the notepad window can be found using findwindow.
I have been doing research on how to set focus to another window, after times of reading "GetWindow" and that stuff all I got is a headache and this:
' Used to get access to Win API calling attributes
