VS 2008 Creating An Over-Lay Window
Dec 17, 2011
I was wondering if it is possible in VB8 to create a GUI that over-lays over a full-screen application (IE, a movie full screen, games or something that takes over the entire screen)
What I want to know is it possible to be watching a movie and click a button and without minimizing or losing focus on the movie a GUI is displayed. This could be handy in many ways to me to create say.. a clock that I can display so I don't have to minimize etc. to check.
I don't want to interact with the GUI, just display it!

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.

The programing I am creating requires window captions for SendKeys. Some windows hide their captions and I want to be able to use Spy++ or create my own way of getting the caption. All I want from Spy++ is Finder Tool, is there anyway of just taking that from Spy++ or how would I go about creating it?

I am using a Thread object to perform a function. This function performs a task and displays its progress in the gridview (like adding rows changing text etc )
The reason I am using a thread for this function is that there is a cancel button on the form. While the task is in progress, user can click on cancel to abort it.
Private Sub BtnStart_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BtnStart.Click m_Thread = New System.Threading.Thread(AddressOf myfunction) m_Thread.Start() End Sub
The function works fine and thread is completed. But calling any method of datagridview after thread is completed ( outside the worker thread ) generates an error- "Error creating window handle".
That's probably because i am not using the invoke method of datagridview for calling its methods or readingwriting properties Do i have to create separate delegates for all the methods properties used in the function ( worker thread)

I am trying to create a simple parent-child form in VB2010. I use a datagridview for each table/datasource and each is bound to the paretn/child table and each table grid fills correctly. What I want is the parent-child relation to enforce filling the child table with only rows that fulfill the current row on the parent. I have created a DataRelation in the form load, but it will not permit a relation between tables in 2 different datasets. If I attempt to place both tables in a single dataset and define the PK-FK relation in the SQL Serve,r I cannot create 2 separate datagrids from the same dataset.

I seem to have some finger trouble creating a new application, here is what I am trying to do: I am trying to create a new solution and under the solution an exe (console project and a set up / deployment project. I have done this in the past and cannot see to do that any more.
Steps:
1. Create a new solution, the solution show in the solution explorer (with 0 projects)
2. Using "add" I create a console application (under the solution) and it shows a module etc. So far fine.
3. At this point the solution explorer windows only shows the console project and the solution itself (that used to show on the top) is gone. Now I am not able to add another project to my solution. I close my screen and then try to open the solution again. It comes up with the console project.

I'm in the process of converting a VB6.0 application to VB.Net (2008 Express). I have a MDI parent form, I'll call mdiBackground, and 4 MDI child forms, frmStatus, frmShow, frmQwerty, and frmSentence.The layout is as follows:mdibackground - has the menus at top and is a container for the child forms.frmSentence - appears at the top frmShow & frmQwerty - appear at the left and when one is closed the other one is in the same position.frmStatus - appears at the right, it has buttons which control when frmShow and frmQwerty are to appear I have a couple of regular forms that act as dialog forms. The Me.Close() works fine on these.

We have a VB 2008 Windows application that is deployed on several hundred computers. For some strange reason only 2 computers out of the hundreds are experiencing the "Error creating Window handle" error. It is happening more consistantly on one machine than the other. Any idea what might be causing annoying error on such a limited basis? (It's a Windows XP machine that it is happening on. That's all the info I know regarding the machine currently.)

I have a 3rd party program that puts up a pop up box and asks the user for input. In Spy++ the original program (I'll refer to this as Window A from now on) is a top level window, and the popup (Window B) is also a parent window. However, when I use FindWindow(Nothing, "Captcha Challenge") it returns 0. I've also used a code snippet from the forums

I searched the forums to look for an answer and I found several good exemples, but unfortunately, none worked for me..I want to make a little program to read an Edit field on another window. I understand the basic. I need to get the handle of the main window (using FindWindow) and then find the handle of the Edit field (Using FindWindowEx). So far, so good... I think I managed to get those two correctly doing:
Declare Auto Function FindWindow Lib "user32" Alias "FindWindowA" (ByVal strClassName As String, ByVal strWindowText As String) As Long Declare Auto Function FindWindowEx Lib "user32" (ByVal hWnd1 As Long, ByVal hWnd2 As Long, ByVal lpsz1 As String, ByVal lpsz2 As String) As Long
Dim hWindow, hText As Long
hWindow = FindWindow("", "Text")
hText = FindWindowEx(hWindow, 0, "Edit", vbNullString)
(Yes the window title is Text :P). Ok now when I do a MsgBox(hText) it does show a long number (not 0) so I believe it found the Edit field (but I'm not so sure on how to verify if it's the right number... tried Spy++ with no luck).Now, this is where I'm stuck. I know I have to use SendMessage() with WM_GETTEXTLENGTH and WM_GETTEXT which I tried maybe in 100 different ways and none of them worked. I either got an OverflowException or my String would stay empty.
