Hi All,
I need to check whether an application is executing. I do not know the class
name of the application; however, I know the window caption of the
application. What would be the first parameter that I should be passing to
the FindWindow API, in order to check whether the application is executing?
Thanks.

Simply pass 'vbNullString' to the first parameter and pass the window title
to the second parameter.

Just extending what Mr MVP said:
Private Declare Function FindWindow Lib "user32" Alias "FindWindow A" (ByVal
lpClassName As String, ByVal lpWindowName As String) As Integer
' Find Window passing the class name only
Dim intHandle As Integer = FindWindow("[Class Name Here]",
vbNullString)
' Show the handle in a messagebox
MessageBox.Show (intHandle, "Find Window Handle via class name")
' Find Window passing the Window caption only
Dim intHandle2 As Integer = FindWindow(vbNu llString, "[Window
Caption Here]")
' Show the handle in a messagebox
MessageBox.Show (intHandle2, "Find Window Handle via Window caption")

I would be glad if you don't always call me "Mr MVP" :-). My name is
Herfried...
Private Declare Function FindWindow Lib "user32" Alias "FindWindow A" (ByVal lpClassName As String, ByVal lpWindowName As String) As Integer
' Find Window passing the class name only Dim intHandle As Integer = FindWindow("[Class Name Here]", vbNullString)
Although your code works, I'd use 'IntPtr' for the handle returned by
'FindWindow' instead of 'Integer'.

I have an Access application with the name: MyAppName®
It has the "®" symbol (ChrW$(&H00AE)) at the end of it.
If I remane the application without the "®" symbol, I can use
FindWindow to close the application, but with the "®" symbol it
doesn't. Unfortunaetley this app is already distributed as MyAppName®
and I cannot change it.
I have tried:
hwnd = FindWindow(vbNullString, "myAppName" & ChrW$(&H00AE))
But it won't work.
Yikes.

How to manage FindWindow() function working properly in ASP.NET application?
In Windows Forms application it works fine. But in ASP.NET it returns NULL
:( Probalby this is because of different context. Something like IIS is ran
under other account or some services cannot interact with desktop.
What exactly should be done to have it working?
Thank you!

Help ....
This is my situation:
I've made two apps, a Managed C# and an Unmanaged MFC. The C# app
communicates with the MFC-app via (Win32-API) PostMessage, done with
the P/Invoke method. One of the activities is "FindWindow". Everything
works fine.
Until ...: I needed the same procedure within another context: now I
need to communicate the C# with a web service (dll) running somewhere
on a Server machine. This doesnot work anymore!

Is looping FindWindow() ok?
We have a simple little c# 2.0 app that’s sole purpose is to look for a
dialog box from another app to pop up and then click it’s OK button. To do
this we use a form with a timer control and some unmanaged code. The app
works perfectly in test but I’m concerned about long term problems/leaks
caused by frequent FindWindow calls (10 per second)? Although the popups
might only occur 50-100 times a day,...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
