VS 2008 SetFocus - Form Never Shows Up
Aug 13, 2010
I am making an app (sorta like a computer lock) that won't let you do anything on your computer until you type in the password. I am using
Public Sub w_setfocus()
Dim f As Boolean
While (1)
f = Me.ContainsFocus()
If f = True Then
Me.Focus()
f = Me.ContainsFocus()
End If
End While
End Sub
End Class
And w_setfocus is run on form1_load. The problem is, the form then never shows up.

If the application is already running, and someone tries to launch it again, set the focus on the already-running program, and exit the one recently launched. I found this, but I don't know how to get the already-running process hwnd. It should be
Dim handle As IntPtr = Process.MainWindowHandle
But that doesn't work.

I got a couple of issues with my windows application VB.Net. I seem to cannot set the form to be invisible before it shows up for a second, there is no option in the properties of a form and also if I set the form to visible = false before the form is loaded it doesn't work.
So this does not work:
Browser.Visible = False
Browser.Show()
and this does work but the form shows up for a second which I am still not very happy with
Browser.Show()
Browser.Visible = False

I'm attempting to improve my MVVM abilities in my next WP7 App (which is written in Vb.NET). I have a textbox that has been given focus and has a WP7 keyboard displayed. I am using command binding and a xyzzer's bindable Application bar (which is excellent).[URL] I want to be able to cancel the focus of the TextBox from the ViewModel, by setting focus on the form. Normally (Non MVVM) I would do this from within the form by calling:

I have a splash form that opens in the following Sub of the main form of the app[code]...
The Splash Form opens and closes fine, but no controls (a text box and a graphic, on a panel) appear on the form. I knew I was probably missing something (this was far easier than anything I found searching), but at least the form opens and closes. The app actually starts with a SubMain, which is only used to control how it opens with it's registered file type.

I have a small non mdi form with only 3 controls. The user can select a name of an animal on a listbox and a thumbnail picture of it is shown on the picturebox. There is also a tton.The tooltip on the thumbnail is quite important as left/right click do different actions but for some reason the tooltip will not display unless the user clicks the form.

I've written a small program that monitors the customer field in Quickbooks and query's a database to determine if there are any important notes for the selected customer. This works fine however, I either need the messagebox or a form to come to the front of all open windows on the system to inform the user that the selected customer needs to be reviewed.
How can I ensure that a form (or messages box) that opens in my program comes to the front of any and all application windows that are open?

Something happened to my project and it got all messed up. I am not sure what happened, but the form I was working on only shows the code and not the project itself(where you design it). I am working in VB2008 Express Edition and do not wish to start over. What happened to my form?

I've got a project that generates a sql query and returns the results. I want to place a time/counter on the form that shows how long it takes to return the query from the server. Basically to count up in seconds from 0 while that sub is executing. Would threading be the best way to do this or is there another way that I'm missing?

I have a splash screen, the default from Visual studio. It loads up, is shown for a few seconds, then, when it disappears, the main form is loaded. Now here is the problem: the main form appears in the back, behind the windows explorer window I load the application from.
The weird thing is that this only happens on some computers, particularly Windows XP machines.I tried a lot of things like BringToFront() or TopMost = true in the on Load event of the form but nothing seems to change this.

I am having this strange thing happen where I have a Module that contains multiple classes in my project. In the Solution Explorer, the module shows up as a Windows Form and if I double click on it to open it, it tries to open the Form Designer. What could be causing VS to think that it is a Windows Form instead of a module?

I have it set so when button3 is clicked that the listbox displays the textfiles in a designated folder.[code]Now what I would like to have happen is a way for: Selected listbox2.item (A.txt, B.txt, or C.txt) read the selected textfile into Textbox1.text(I want to click on A, B, or C and have it just open/read that textfile into the textbox.)I have a feeling this is something simple - but for some reason I am having trouble grasping it.

Simply saying I've added an Notify Icon to my project and then added context menu showing up when the left mouse button is pressed. The problem is that with the context menu some blank form is showing in the taskbar. There is no such form within the project.Does anyone know why it may be happening or how to get rid of the effect? I might add that I have other context menu attached for mouse right click button and it works fine, no blank forms and such showing on the taskbar it's just the left mouse button that works that way.Here is the code that I am using to show the menu:(the visible state to false is necessary for the other menus not to pop up with the one i want... unless anyone knows better method)
Private Sub NotifyIcon_Click(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles NotifyIcon.Click
If e.Button = MouseButtons.Right Then
