    How many maximum number of messages that I can send to a message to a WIN32 window?

    How many maximum number of messages that I can send to a message to a WIN32 window?

    If window is in progress and doing processing for a while and can discard the new message.

    So what is the maximum length of the queue of a window?

    Limit of posted message is 10,000.

    But you can configure this limit via below registry key:
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows\USERPostMessageLimit
