VS 2010 Check If App Has Focus?
Aug 21, 2010
So, I know from the user32 dll, and I set that as focused.
Is there a easy way of determining if the app has focus?
im using send keys, and i dont want it typing the keys and such, if the app doesnt have focus.
Also, if you click off of it, etc... It's more so a pause thing...
The only other way I can think of, is setting it so,
If myapp has focus, then pause the keysends.... then if it loses focus, assume the app i want has focus again.

If creating a dictionary program. when use copy some text on clipboard it will give the meanings of copied text in a form visible on system try. I want to close the form when user click any where on his/her screen. But if user want to copy some text from meanings from will not close i added more then one dynamically created richtextboxes in a tab control to show number of meanings. My code is working great accept one thing when user scroll the richtextboxes form will close itself. It seems scrollbars are not the part of richtextbox.
Dim s As Boolean = True
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
If MouseButtons.ToString = "Left" Or MouseButtons.ToString = "Right" Then
If s = True Then
If InStr(LCase(Me.ActiveControl.ToString), LCase("Label")) Then
Me.Close()

I'm trying to create a grid usercontrol.This means that when i press "UP" it goes to the cell above (...so on for all directions) tab goes to the right and enter goes down.Now all these keys (excluding enter) change control focus so i've got a problem using them.How can i lock focus on the control so that these keys won't change it and so that i can use these keys for other things?

I have an application that just stores shortcuts to most used applications on users desktops. My problem is that when the machine loads after they login the app window looses focus and sometimes doesn't show in the taskbar. I tried to use Me.Focus() but that just gives the treeview focus and not the form itself. I mean the parent has focus in the treeview but the form is not highlighted, I can then click on the form and it gets selected.
What is a good way to get the whole form focus? I used me.focus in the form load too.

Does anyone know if you can remove focus from all controls on a form so a user doesn't inadvertently cause action on a control when it's unintended such as hitting Enter at the same time your app appears causing some action to occur? Do you have to leave focus on at least one control?

I have a form with 3 controls that have TabIndex values set:Combo box (cboPostpone) - TabIndex = 0 Postpone Button - TabIndex = 1 Install Now button - TabIndex = 2
The code below is part of the Timer1.Tick event The code below seems to change the focus but then when trying to tab through the controls, it stays on the combo box.
[Code]...
Lastly, I removed cboPostpone.Focus() command from the Timer1.Tick event and move it to the Postpone button Click event. I run the focus command right after the me.hide command. I delayed it the first time and it came back with the Postpone button in focus again instead of the combo box.

A form's key events will fire when you press a key. Place a control on that form and it won't happen any more because that control has focus. There are exceptions to this however as you will see if you place just a h or v scrollbar on the form. The key event will fire because the scrollbars can't receive focus as is demonstrated by the following
Private Sub ScrollBar1_GotFocus(ByVal sender As Object, ByVal e As System.EventArgs) Handles VScrollBar1.GotFocus
Debug.Print("Scroll GF")
End Sub
[code]....
So I've made my own special scrollbar usercontrol and i can't figure out how to have it leave the key events alone. I'm pretty sure that the problem is that my usercontrol can receive focus at the moment.
I found that the way of doing this is "SetStyle(Windows.Forms.ControlStyles.Selectable, False)". I put that in the new event of my usercontrol and now it looks like this:
Public Sub New()
' This call is required by the designer.
InitializeComponent()

Is there a more efficient/easier way changing the backcolor of a control when it has focus and lost focus? Let's say I've got 10 text boxes. Right now I would have 20 different events...10 for Enter event and 10 for Leave event. Of course, entering would change the back color to "green" and leaving would change it back to "white".

Here 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.

I want to prevent my application from losing focus, untill I close it. (so that I can not click on ANYTHING else, untill I'm done with it. period.)I've tried using Me.Focus() on a timer, but that doesn't do s***...I've also tried countless API's out there, but I seriously can't get any of them to work.. my form simply does NOT want to stay in focus! It's driving me crazy! What the hell am I doing wrong?

I've got a lose focus textbox which when data in entered and the tab key is hit the code is executed as expected and a message box appears informing the user of the outcome. However when I used a barcode scanner with a tab function embedded, the code is executed and the data is inserted into a database but the textbox to say if the request was successfully completed or not does not show as expected.

I have two forms in an application. One is he background and then I show another keypad form called with the show() method (not showDialog) because I need to perform some validations on btn click.
The kepad has 10 buttons and an Enter Button. The problem is that the form keeps loosing focus (I checked this with a messagebox which keeps poping up once for focus=true and again for focus=false, it continuously keeps losing and gaining focus) so it does not process any keypress events untill i click somewhere on the form. I tried using me.focus() in form load event but to no avail. The forms TopMost property is also set to true.

Select Case e.KeyCode

I have googled this and found older vb codes that do not work in 2010. The user, in this case a "cheater/hacker" isn't suppose to be aware of a running program that checks memory and some other information. I have succesfully read the values of certain memory adresses in my program, now I need to send those values to another program secretly opened as a date and time sort of thing. The program checks for malicius attempts to edit memory or edit information inside the software and it automaticly deletes all the data or does a "ban" if somebody attempts to freeze memory and edit it.
So the problem is how to send this data to program out of focus, I can send strings with appactivate but it will open my security program to screen everytime memory changes witch is almost every milisecond so it's almost useless cause it keeps switching focus. I need something to send it out of focus, so my question is;
I make a hook between my program and my security program, send messages/strings out of focus or in tray?Also it would be good if I could make my program "invisible" so he can't be seen even in tray and still keep working.

I wanted to know if there is a way to stop my webbrowser control from steeling my cursors focus? i mean its bad enough i have to hear the god damn thing in the background as it refreshes the pages.
What i built is basically a program that checks my marks on my school website and verifies to see if any new grades have been added. The program then notifies me by sending a text message to my phone. The program is in its beta stage and has lots of sloppy logic and code. anyways i hope someone knows how to keep my focus from running off of msn when I'm trying to type.
And as for the variables and coding. i know i have made it sloppy with unnecessary variables. I'm planning on cleaning that up when i have the time.
