If you open several FullTilt games table, you can see that when on a table is required action it jumps automatically in foreground, BUT WITHOUT TO BE ACTIVATED, so that it title bar is grey and not blue. The window is the top window for my eyes, but it is not active.Now the question is: how to get the Hwnd of the topt VISIBLE desktop window (the window that is over all the other windows), also if it is not the active window?I can't use the GetForegroundWindow Api, becouse it gives the Hwnd of the top ACTIVE window...
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?
how to place a visible image in the splitcontainer so it would be obvious for users to see that the area is movable. Like the split container in SplitContainer Class(System.Windows.Forms) which has the gray with
I want to be able to hide the left hand side of the screen and right hand side of the screen at the beginning of the program.
Then when the user presses create new button the left hand side of the screen becomes available so they can create the new item. Then when they press save it comes back to the middle datagrid only.
Then I want to add an event when the double click on the datagrid row (data is programmed in to the datagrid in the code) the right hand side of the screen becomes visible then when the button allocate is pressed the right hand side disappears again just leaving the datagrid.
I am running VS2008 and am using VB2008. I have created a solution file with a Windows Form Project. It contains one form. I created a class project called DataAccess. I selected that project and created a data source. Now I see the XSD for that data. If display the "Data Sources" window I see the datasource. So far so good. If I select the Windows Form project, and then display the "Data Sources" window I get an empty window with a "Add New Data Source" button/link. How do I make the data sources created in the second project available to the first one?
I have been watching the videos for creating n-tier apps that suggest adding a third project to the solution called DataEntities. I did that. I then click on the XSD in my DataAccess project. Then in the properties of the XSD I change the "DataSet Project" property to point to my new DataEntities project. When I save the DataAccess project the DataEntities project gets a file added to it as expected. But then the Data Sources window is empty no matter which of the three projects I select.
Clearly I am doing something wrong. The videos all show the ability to see the data source in the "Data Sources" window after setting up this three project structure. One other thing I noted. In most of the pictures in articles showing the Data Sources window. The top most entity in the window is the project file itself. Then in a tree structure you would see the various data sources under that top most entity. When I was able to see something in the data sources window, the top most entity was a data source NOT the project file, with the data sources under it.
Any idea what I am doing wrong? It seems like I need to do SOMETHING to make the data sources in one project visible to the others. And possibly something to make a datasource visible once split apart using the "Dataset Project" property.
I'm making a program running on background that monitors users button click on a specific program, I need to know where this person is clicking. Is there a way to make a virtual map (not visible to the user) of the window this person is looking at and clicking? I need know where this person is clicking so I can take a specific action and show a result to another monitor output.
I dragged and dropped a label from the toolbox onto a form (Label6) and stupidly went to the properties window and set "Text" to blank. Label6 shows when the program is run using F5 but does not show on the design surface if I want to move or remove it. How do I get it back onto the design surface or remove it completely?
I am trying to get the handle of a window to get it's title text. I tried the WindowFromPoint, but it will get any control, not just a window. How do I get the window that the mouse is over?
I have a handle to a window using the FindWindowA() function in the User32.dll (Windows API) and I would to get focus on that window at a later time in my program. how to do that with either a .NET function or User32.dll function? Is there a totally .NET way to get the window handle and focus?

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 am following some instructions that apparently work with vb6, but as i have downloaded the lastest version of visual studio i think its up to version 10.

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:
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.
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.
I made a program that is started and running in memory and minimized to the system tray.
When it is first launched it registers global hot keys in windows.These hot keys are used for resizing the current focused window. I'm trying to use it so you can hotkey windows to resize to half the screen, a third of the screen, etc... For instance, if I have two notepads open and notepad 1 is focused and I hit Ctrl+Shift+LeftArrow it will resize notepad1 to the left and half the size of the screen. I have notepad 2 focused and Hit Ctrl+Shift+RightArrow and resize notepad2 to the right side of the screen. So, I can easily see both windows at once.Now, I can successfully get the focused window handle when the hot key is pressed. I'm stuck at this point.
I have a window that I need to activate and the window name does not work in AppActivate("WindowName") because this does not work with partial captions etc... and the window name will be different depending on user. That being said I am able to use "GetwindowhandlefromPartialCaption" to retrieve the # value of the window name or handle. Is there a way to convert this or extract the name from the handle ID to use with AppActivate?

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 have a piece of vb.net code that finds the nunit.exe process like thisDim proc2 As EnvDTE80.Process2 = dbg2.GetProcesses(trans, "myPC").Item("nunit.exe")now I'd like to press a button on the window of that process so I do thisDim ButtonHandle As IntPtr = FindWindowEx(X, 0, "Button", "Run")SendMessage(ButtonHandle, &HF5, 0, 0)
I have inserted the following code depicting a procedure that can place the cursor at a particular location within a Rich textbox. However, I am unable to get the Hwnd handle to run without an error.
Would someone advise if the SendMessage arguments are correct and how do I access the RichTexBox Hwnd window handle for this procedure.
