does not seem to work, the memory is not released as when I call the DLL once again, it will continue to increase the memory. How do I release the memory?
In general, you declare an extern
function, and don't worry too much about memory usage. Windows uses this DLL internally anyway.
[DllImport("User32.dll")]
private static extern short GetAsyncKeyState(System.Windows.Forms.Keys key);
private void button1_Click(object sender, EventArgs e)
{
short state = GetAsyncKeyState(Keys.D);
switch (state)
{
// ?
}
}
