Api - SendMessage

[Peyote]

does any one knows why is it that when i call a WM_ message
for the API "SendMessage" function,
it is always an empty WM_
while it suppose to be signed &HD or &C1 values or something like that ?

[da_silvy]

i don'ts know what yous mean?

[Megatron]

Did you remember to define the constant?

[Peyote]

this is exactly my problem
lets say i want to use the WM_CLOSEWINDOW,
how do i know what to define ?????????????
const WMCLOSEWINDOW = &???????

[da_silvy]

you find out

it's WM_CLOSE

the value is &H10

Private Const WM_CLOSEWINDOW = &H10



Use the API viewer

Private Declare Function FindWindow Lib "user32" Alias "FindWindowA" (ByVal lpClassName As String, ByVal lpWindowName As String) As Long
Private Declare Function GetWindowText Lib "user32" Alias "GetWindowTextA" (ByVal hwnd As Long, ByVal lpString As String, ByVal cch As Long) As Long
Private Declare Function GetWindowTextLength Lib "user32" Alias "GetWindowTextLengthA" (ByVal hwnd As Long) As Long
Private Declare Function SetForegroundWindow Lib "user32" (ByVal hwnd As Long) As Long
Private Sub Form_Load()
    Dim MyStr As String
    Dim dosHand As Long
    dosHand = FindWindow("tty", vbNullString)
    MyStr = String(GetWindowTextLength(dosHand) + 1, Chr$(0))
    GetWindowText dosHand, MyStr, Len(MyStr)
    AppActivate MyStr
    SendKeys "%~"
    AppActivate MyStr
    End
End Sub

thanx again
:-)

you see, the code you gave me sets the dos window to a normal size, i tried playing with it, but..

i tried already:
ShowWindow hwnd, 3 (API function), but it will return a big dos screen (not totaly full screen)

then i tried:
SetWindowPos(hWnd, HWND_TOPMOST, 0, 0, 0, 0, wFlags)
but it only sets the focus to the minimized tab of the dos window on the toolbar, but not resizing it.

what happenes it that when i move from the dos program to the vb program, it makes the dos window minimized, and i want to return from the vb program to the dos program but it wont return to the dos's TOTALY FULL SCREEN mode (the one you can make by pressing Alt & Enter on a dos window)

i hope you are not troubled by me but chalanged :-)
thank you
