WM_USER ?

Public Const WM_USER = &H400

hm...
kan du finde ud af dette så:

WM_MCOMMAND - which should be defined as WM_USER + 200

altså, det er i en funktion jeg skal bruge det.
det såkaldte SendMessage:
SendMessage(mHwnd, WM_MCOMMAND, cMethod, 0L)

Jeg ved jo ikke hvad du vil, derfor kan jeg heller ikke svare, uddyb

ok..
dette er hvad jeg vil (det er taget fra mIRC help):

Applications can now use SendMessage() to communicate with the 32bit mIRC.

Performing Commands
The following call to SendMessage() makes mIRC perform the commands that you specify.

  SendMessage(mHwnd, WM_MCOMMAND, cMethod, 0L)

  mHwnd - the handle of the main mIRC window, or the handle of a Channel, Query, etc. window.

  WM_MCOMMAND - which should be defined as WM_USER + 200

  cMethod - the way in which you want mIRC to process the message, where:
      1 = As if typed in editbox
      2 = As if typed in editbox, send as plain text
      4 = Use flood protection if turned on, can be or\'d with 1 or 2

  Returns - 1 if success, 0 if fail

jeg har prøvet dette men det virker ikke..
der sker ikke noget..
SendMessage FindWindow(vbNullChar, \"mIRC32\"), WM_USER + 200, 1, \"/echo hej\"
