View 2 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.
View 1 RepliesI am trying to find the handle of the child window for the Yes button in the User Account Control window so i can click it. This window has a structure with a few child windows with the same name.
Dim hwnd As IntPtr = FindWindow(Nothing, "User Account Control")
Dim hwnd2 As IntPtr = FindWindowEx(hwnd, 0, "DirectUIHWND", vbNullString)
Dim hwnd3 As IntPtr = FindWindowEx(hwnd2, 0, "CtrlNotifySink", vbNullString)
Dim hwnd4 As IntPtr = FindWindowEx(hwnd3, 0, "Button", "&Yes")
There are multiple CtrNotifySink with its own Button child window or other child windows. How do i search thru the different CtrNotifySink window to find the one that contain the Yes button so i can send a click to it? I do need to find it before i can send a click, right? because i try just sending it to the main window with sendmessage and nothing happen.I even try sending it directly to the handle found by spy++ of the yes button with bm click but nothing happen?
How can I get the handle of the window that is below (or behind, whatever you call it) the foreground window?
View 2 RepliesThere is a panel which contains 2 components: a label and a TreeView. The hierarchy, obviously, looks like this:panel1 // handles Enter event
- label1
- treeView1
I need to do some UI updates when user starts interacting with any of these 3 controls. My attempted strategy was to catch the Enter event of the panel, which would fire when user clicks a label, or TreeView. This way, I can write only one (1) event handler instead of several. While it worked for the TreeView, it didn't work for the label. When I click the label, I don't get the Enter event on the panel. Whats different about the label control? I could handle the Click event of the label. At the same time, I wonder what the other solutions might be.
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:

I'm trying to make use of some functionality from an external app in my program.
My problem is this:
My program manages to start the external app correctly and I can even get the WinHandle correctly if I don't use "ProcessWindowStyle.Minimized" when starting the app.
If I start the app minimized, WinHandle = ProcID.MainWindowHandle returns a 0 and as I understand it, it's
because the app is hidden in the system tray.
How can I start the app minimized and then get the window's handle once it has been minimized?
I've tried various functions like FindWindow and BringWindowToTop but none of them seem to work.

I searched a bit for an equivalent.

View 3 RepliesI'm using a third party dll for my project and one of the function that is provided by the dll use form handle as one of the argument. But when i call the function, I'm not using any window form and it's just called from another class. So what value i should put for that argument?Here's the example of that function:
AVS_Measure (device_handle, form_handle, no_measurement)
After this function has been called, it will send message to the form_handle argument whether the measurement data is available and valid.I called this function from another class just for triggering start measurement and i have another function to retrieve the data. I do not have any form associate to it, what value i should put for this argument?
I'm writing a DLL library that interfaces to a USB device using winusb in VB.NET.
Since it's a DLL, I have no window, and it's possible that users of my library will also not have a window (command line apps, for instance).
The examples I've seen that detect device attach and detach all use RegisterDeviceNotification which requires a window handle to receive the attach/detach messages at.
How do I receive these messages directly into a function without a window to get a handle from?
I have the below code. When I execute this code, the handle is different between the Load event and the Shown event. I thought the handle was static for an instance of a window. What could cause the handle to change? The only other thing the form is doing is setting itself to invisible and setting the ShowInTaskbar = False in the Activated event.

to be so simple turns out to have me scratching my head.I have a program that monitors input inside of Quickbooks. When a customer is entered into a sales order my program checks my database for any special information and if it exists, opens a TopMost window to the lower third of the screen with the information showing that is special to that customer. The problem I have is that when the customer is found and the window opens, focus is taken away from Quickbooks and given to my newly opened form. Is there a way to prevent this so that the users input isn't interrupted?
With frmMessage
.Width = Screen.PrimaryScreen.WorkingArea.Width
.TopMost = True

I can't find anything about a Visual Basic application that doesn't open with focus I've written an application that takes the current clipboard text and changes all letters to lower case, then the first letter of every word to upper case (the first letter after a space), this is for when I download a file that I want to look neat (such as an mp3 audio file). It's output is then placed in the clipboard to be used as the filename (or text).
I've set a shortcut key (Ctrl+Alt+X) to open the application by placing a shortcut in Accessories so it runs instantly whenever I hit the shortcut combination. However the application steals focus when it runs, so as soon as it ends I lose focus altogether, and I then have to Alt+Tab and find where I was when I used the shortcut! There are 2 possibilities for my application, the latter is what I really want, but the former is OK for me:
1. I use Ctrl+C to copy, The application runs and then switches to the original focus (focus before using my shortcut combination), I can then Ctrl+V to paste.
2. The application runs WITHOUT stealing focus altogether, this way I can have the application copy the selected text for me, and replace it aswel
