Hi,

I have c# parent window and a c++ child window.

I am writing c++ child window postion and coordinates to registry so that if again c++ window is launched from c#, it retains the same position for the current session

C++

WINDOWPLACEMENT wp;
GetWindowPlacement(&wp);
AfxGetApp()->WriteProfileBinary("MainFrame", "WP", (LPBYTE)&wp, sizeof(wp));

But if parent window itself is closed i want to delete that registry so that for first time the c++ child window takes default position and coordinates.

So how do i delete WINDOWPLACEMENT registry created in c++ from the c# code

Language has nothing to do... You simply use .NET functions that manipulate registry instead of Win API ones.

Solution: Don't do this
Using Windows Registry Hive for this is overkill.

Note: The language used to create a registry entry have no impact on the way to delete the same registry entry, whatever is the language used to do it.

You simply need to set variables to store the window position, the variables values simply have to persist between child window calls.

It is quite simple to manipulate registry from c#.
Read, write and delete from registry with C#[^]
