How can I hide my application from the ALT+TAB feature to toggle between
programs in Windows?

WINAPI WinMain(HINSTANCE, HINSTANCE, LPSTR, int)
{
DWORD dwExStyle = GetWindowLong(Application->Handle, GWL_EXSTYLE);
dwExStyle |= WS_EX_TOOLWINDOW;
SetWindowLong(Application->Handle, GWL_EXSTYLE, dwExStyle);
//...
}
However, do note that this approach removed the application's default
taskbar button as well.

It does remove the taskbar button but I can still Alt+Tab to the program.

in the dialog, then it has to be picking up one of your TForm windows
instead of the TApplication window. What is your EXACT setup?

I changed the BorderStyle from bsNone to bsToolWindow and it no longer
shows up in the Alt+Tab list; however, it now has a titlebar and it's not
what
I want.
The program Just shows some small brief info on a bsNone dialog then
animates off the screen so I don't want a titlebar so the user can drag it
elsewhere on the desktop.

Ok I changed the BorderStyle to bsDialog and added the following code
to remove the Caption because it wouldn't remove it with the
bsToolWindow option.
.h
private: // User declarations
void __fastcall CreateParams(TCreateParams &Params);
.cpp
void __fastcall TMain::CreateParams(TCreateParams &Params)
{
TForm::CreateParams(Params); // call base class first
Params.Style &= ~WS_CAPTION; // then clear caption bit
}

WM_NCHITTEST message. Pass the message to the default handler first. If it
returns HT_CAPTION then change the message result to HT_CLIENT instead.
