Hi Luc,

Here is what I tried, but it did not work for me

private void btnTest_Click(object sender, EventArgs e)
       {
           SetWindowPos(this.Handle, HWND_NOTOPMOST, 0, 0, 0, 0, SWP_NOSIZE | SWP_NOMOVE | SWP_NOZORDER);
        }

And here is my pininvoke code

private static readonly IntPtr HWND_TOPMOST = new IntPtr(-1);
        private static readonly IntPtr HWND_NOTOPMOST = new IntPtr(-2);
        private static readonly IntPtr HWND_TOP = new IntPtr(0);

        private const UInt32 SWP_NOSIZE = 0x0001;
        private const UInt32 SWP_NOMOVE = 0x0002;
        private const UInt32 SWP_NOZORDER = 0x0004;
        private const UInt32 SWP_NOREDRAW = 0x0008;
        private const UInt32 SWP_NOACTIVATE = 0x0010;
        private const UInt32 SWP_DRAWFRAME = 0x0020;
        private const UInt32 SWP_FRAMECHANGED = 0x0020;
        private const UInt32 SWP_SHOWWINDOW = 0x0040;
        private const UInt32 SWP_HIDEWINDOW = 0x0080;
        private const UInt32 SWP_NOCOPYBITS = 0x0100;
        private const UInt32 SWP_NOOWNERZORDER = 0x0200;
        private const UInt32 SWP_NOREPOSITION = 0x0200;
        private const UInt32 SWP_NOSENDCHANGING = 0x0400;
        private const UInt32 SWP_DEFERERASE = 0x2000;
        private const UInt32 SWP_ASYNCWINDOWPOS = 0x4000;

        private const UInt32 TOPMOST_FLAGS = SWP_NOMOVE | SWP_NOSIZE;
        private const UInt32 NOTOPMOST_FLAGS = SWP_SHOWWINDOW;

        [DllImport("user32.dll")]
        [return: MarshalAs(UnmanagedType.Bool)]
        public static extern bool SetWindowPos(IntPtr hWnd, IntPtr hWndInsertAfter, int X, int Y, int cx, int cy, uint uFlags);

Hi,

two things:

1. "did not work for me" isn't helpful; what did it do? and what did it not do that you were hoping to get? please be precise.

2. why is this in a new Click handler, I was expecting this to go in the else block, as counterpart to your SetWindowPos(this.Handle, HWND_TOPMOST...).

Smile | :)

It did not remove the topmost flag as the application is still set to topmost. I would like it to go from a topmost application back to a standard z ordered application as it is before the topmost flag is set.

I was testing it with a test button for simplification is all, as soon as I get a working example I will then incorporate it into an else block

Re: Problem with setwindowPOS and returning from topmost to standard window position?

The problem is that your X, Y, cx and cy values are all zero, and when you switch to NoTopMost, you have omitted the flags to keep the size and position. Edit your code and replace the definition of NOTOPMOST_FLAGS with the following.

private const UInt32 NOTOPMOST_FLAGS = TOPMOST_FLAGS | SWP_SHOWWINDOW;

Had you explained exactly what happened when you ran your code we could have helped earlier.

Re: Problem with setwindowPOS and returning from topmost to standard window position?

Thank you.

Strangely enough when I have the above code in a separate button it removes the topmost flag correctly, but when I have it at the end of the send.keys function it does not remove the topmost flag? Any ideas on what could be causing that?

Sure thing, the first block is my Pininvoke code, then the standard function and then the test button.

The standard function code will put the form to topmost, but will not remove the topmost flag. The test button will remove the topmost flag after the standard function places the topmost flag.

I cannot see anything wrong with that code, and the documentation does not give any further ideas.

I don't know why, but the addition of the thread sleep as pictured below fixed it?

tbxXCoordinates.Text = "";
tbxYCoordinates.Text = "";

Thread.Sleep(250);
SetWindowPos(this.Handle, HWND_NOTOPMOST, 0, 0, 0, 0, NOTOPMOST_FLAGS);

I wonder if using SendKeys.SendWait Method (String) (System.Windows.Forms)[^] instead of Send might have the same effect?

Sure, but not exactly like you see in an ASP.NET MVC app.

The version used in WPF is far more powerful and flexible. The pattern is called "Model View ViewModel[^]".

hi all
I have created in windows application and also one windows service using c#. this windows application has the database connection and do some functions etc which i want to daily repeat. so i have created the windows service. when i debug windows service in debug mode everything works fine. but after installation of windows service it is created the processes of that windows application. but that windows application is not initiating..

Services can't start UI EXE apps directly: they are running on Session 0 and cannot create or display a UI at all.
I haven't tried it myself, but this may help: Subverting Vista UAC in Both 32 and 64 bit Architectures[^] - will it work in Win10? Dunno ...

Then do i have to create the console application instead of windows application to launch through service.

No. A Console app is also a UI app - not a GUI, but a UI. Services cannot interact with the desktop, or initiate any interaction - because they can be running before a user has logged in, so there is no user to interact with!

the app which is running at the backend through service doesn't have any user interaction. It just connect to database and run some procedures, get some rows from database and send mails to the participants.

Please suggest how to do that.

You mean instead of creating another external exe whole code has to be written in service itself.
what i understood correct?
