.net - Hiding Window Loses Window's Functionality?
Aug 5, 2011
I have a vb.net application that, when a short cut is pressed, a window pops up. I also would like to make it completely invisible, unless the short cut is pressed. In the default class that houses my code for noticing the short cut and coordinating the events of the short cut, I have placed the following code:
Me.ShowInTaskbar = False
I have isolated this code as the issue. The issue is that my application does not work when it is not shown in the taskbar. This is only the default form - for the pop up window I have a separate class. How can I create a workaround for hiding the window in the taskbar and hiding it in general?
Btw, this is my hotkey code:
Public Const MOD_ALT As Integer = &H1
Public Const WM_HOTKEY As Integer = &H312
Public Declare Function RegisterHotKey Lib "user32" (ByVal hwnd As IntPtr, ByVal id As Integer, ByVal fsModifiers As Integer, ByVal vk As Integer) As Integer
[Code]....

I have a custom WPF window defined as:
<Window x:Class="MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" MinHeight="300" Height="350" MinWidth="600" Width="700" ResizeMode="CanResizeWithGrip" AllowsTransparency="True" WindowStyle="None">
I found a class online that creates drop shadows, shown below. This works well, even with a resize grip, until I maximise the window. Once I maximise the window or change the window state of another window (eg. Visual Studio), I loose the drop shadow and I cannot get it back.

I have been working on a program to hide windows for an active process. I found some examples on the internet explaining how to do this. The problem, however, is that after I hide the windows I cannot get them back. The process still shows up in task manager but i cannot restore the window..
Imports System.Runtime.InteropServices
Imports System.Diagnostics
Public Class Form1

I was just googleing this, and i came across this
Dim p As New System.Diagnostics.Process
p.StartInfo.WindowStyle = ProcessWindowStyle.Hidden
p.StartInfo.CreateNoWindow = True
p.StartInfo.UseShellExecute = True
p.StartInfo.FileName = "cmd.exe"
p.Start()
Does that mean that i could show it again? if so, is there a code that can do this?Also, if i wanted to get the window that the user is currently in, how would i be able to hide that?

I'm making a webbrowser and coding the ctrl+f function has proven to be too complicated. I therefore decided to link buttons with the ctrl+f window that already exists in IE. What i want to do now is hide the ctrl+f window that pops up. When I hide active window at the moment it hides the webbrowser and not the ctrl+f window that pops up.

So i want to start an application with my vb.net app and it should start as a hidden process, meaning no window and nothing in the task bar, only in the task manager ofcourse.
This is what i do
Dim fov As New Process
If CheckBox2.Checked = True Then
RichTextBox1.Text = RichTextBox1.Text & vbCrLf & "* - Launching"
fov.StartInfo.FileName = ("test.exe")
[Code]...
This does not work.. I have also tried the "fov.StartInfo.CreateNoWindow = True" command which does not work either. I can live with a solution that would start the window minimized instead of totally hidden.

In VB.NET, I have a LinkButton that, when clicked, creates a report. We want to disable this functionality based on whom is logged into the system. I have a session variable to indicate whether this should be visible or not but when I set idLinkButton.visible = False, it has no effect. Any ideas on what I need to do to be able to turn this on and off?

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?

I have a VB.NET application that uses Managed DirectSound to capture audio.Everything works just fine until (a) the application is minimized or (b) the application is completey obstructed (covered) by another window.
The thing is that the CaptureBufferDescription structure does not include a GlobalFocus property so I don't know what to do to let my application continue capturing when the main window is hidden.
Here's the basic initialization code I'm using:
' Create a buffer description object
bufCapDesc = New CaptureBufferDescription()
With bufCapDesc

border of that said window so the only place the mouse can't click the titlebar and the minimize,restore, and maximize button. The height of the titlebar depends on what OS the user is using so I'm having trouble because I can't give a definite value for this. How do I detect the height. and also for border i'm not sure if the borders have different widths with different operating systems. I'm using windows XP on classic mode, when I change to the themed mode, the height of the title bar changes so it won't work.

I am looking to close the application when I click a cancel button in a login page, but I don't want to do it in such a way that Window 2 closes itself, but by sending some notification to Main Window, and Main Window closes the application. Here's the code that I have so far:
(in loginPage)
Public Event CloseApp As EventHandler
Private Sub CancelButton_Click(sender As System.Object, e As System.Windows.RoutedEventArgs) Handles CancelButton.Click

If you have ever noticed in the Task Manager, when you right-click on the running task, you have many options which include 'Minimize' and 'Maximize'. Is there anyway to do achieve this in vb?

I am creating a window that is a generic keypad for editing numerical values on a touchscreen. I would like to press an 'edit' button to create a copy of the keypad window/bring up a reusable version of the same window (I don't care), but pass in parameters: the old value I'm manipulating, and a title to be displayed above the number pad. I would like the user to be able to type in the new value, then press the 'done' key to submit this value and have it sent back to the main application window into my custom control that contains a text box.(I have the number pad's layout sorted out already; I'm already using a variation on it to set a global password 'access level'. It's getting the information in and out that has me scratching my head.) [code]

I have the following function that should make the window always on top of other applications.
Private Declare Function SetWindowPos Lib "user32" _
(ByVal handle As Long, ByVal hWndInsertAfter As Long, ByVal x As Long, ByVal y As Long, _
ByVal cx As Long, ByVal cy As Long, ByVal wFlags As Long) As Long
[Code]....
The problem is that it reduces the window size so that you can only see the title bar and min/max/close buttons. Also, even that does not stay on top of other windows.
I have used this function before on a windows 7 machine (instead of xp which this one is on) and it worked fine.
