Find The Handle Of The Child Window For The Yes Button In The User Account Control Window?

Mar 20, 2010

I 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?

Window That Acts Like MDI Child Over Chart Control

Jul 2, 2011

I need a tool window to act like a mdi child over a chart control. I can't use mdi because I'm using the krypton control ribbon component and they pretty much use all the mdi code in the background. Anything I do mucks it up. So I need a window to float over another control and be bounded by the real estate of that control.

I am developing an application that reads an MDI applications child window and grabs the information from a control such as a textbox or listbox.

Get The Window's Handle Once It Has Been Minimized?

Mar 1, 2012

<DllImport("user32.dll", SetLastError:=True)> _
Private Shared Function SetActiveWindow(ByVal hWnd As IntPtr) As IntPtr
End Function

[Code]......

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.

Third Party DLL With Window Handle?

Oct 17, 2011

I'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?

Use RegisterDeviceNotification Without A Window Handle?

Apr 5, 2012

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?

Window Handle Changes Between Events

Aug 1, 2011

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.

Child Window On Top?

May 19, 2009

(vbnet 2008, windows forms)I have a main form (not MDI) with a menu that will open another form as a window on top (I have already set the TopMost property to true). My problem is that it will set this window on top of everything that I open (any program). How can I set this window to be on top of just the main form? I guess I have to declare the main window as its parent, I tried the code below but it didn't work...

Code:
Private Sub FilterToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles FilterToolStripMenuItem.Click
Dim frm As New frmFilter

Error Creating Window Handle In A Thread?

Sep 14, 2011

I've a little program that has got tabControl with 2 tabs - "results" and "log". My idea was that when an error occurs the tab will switch automatically on tbLog to show what the problem was. Most arguably the problem is in threading. This is the code that..I use:

Dim thread As New Thread(AddressOf ExecuteQuery)
thread.Start()

ExecuteQuery executes the query and I'm making an error deliberately to see if I'll be automatically switched to the log tab which is in Try-EndTry procedure:

tbGrid.SelectedTab = tbGrid.TabPages(1)

The program indeed switches to tabLog (which is number 1) but I don't see any controls on it (txtLog), then when I'm trying to switch tabs a couple of times I get "Error creating window handle in a thread". I read other forum threads about it where people as how many controls do they have in their programs but my program does not exceed 70 controls on a form.
