sorry:

I´m looking for something like Application.DoEvents() but it must clear
"the"
queue.

..I.
 
DoEvents process messages and clears the queue but I don´t want to process
messages, i want clear the queue only.

thank you

erm, Where is PeekMessage?
What DLL?

I´m trying it:

[DllImport("Msgque.dll")]
extern static bool PeekMessage(out MessageWindow Msg, uint hWnd, uint
wMsgFilterMin, uint wMsgFilterMax, uint wRemoveMsg);
public static void ClearMessages()
{
MessageWindow msg = new MessageWindow();
while (PeekMessage(ref msg, 0, 0, 0, 1))
{

I get a 'System.NotSupportedException' exception in PeekMessage call.

hmn?

[DllImport("coredll")]
extern static bool PeekMessage(out Message Msg, uint hWnd, uint
wMsgFilterMin, uint wMsgFilterMax, uint wRemoveMsg);

public static void ClearMessages()
{
Message msg;;
while (PeekMessage(out msg, 0, 0, 0, 1))

Actually, the CF Message structure won't do.
Define the MSG structure like this:

struct MSG {
IntPtr hwnd;
uint message;
IntPtr wParam;
IntPtr lParam;
int time;
int ptX;
int ptY
}

Manually P/Invoke GetMessage and don't call DispatchMessage.
