Where the Arrows are

Postby Jerry Fielden » May 24, 2006 15:10

Here's something thats a little funny that deals with Inkey and the Mouse cursor.


Mouse and Inkey In Console Screen Mode 0.

If I make an area of my screen Mouse click on sensitive and when I left click on that area, the program is instructed to do something. That works alright.

Now if I by accident happen to have my Mouse cursor resting on that sensitive area, and I start typing something in an another area of the Screen below it using Inkey$, the Mouse sensitive area becomes activated as if I clicked the Left Mouse button. I have to make sure where my mouse arrow is resting before I can start typing.

Now if I type something above that sensitive area, it doesn't do that. It will go ahead and put the characters on the screen without clicking the left mouse button when I hit a key.

This is happening to me in XP Home, Windowed, Console mode 0.

I tried this and I have no change in the button state when pressing keys.

Code: Select all

do
getmouse x,y,w,b
locate 1,1
print x,y,w,b
k$=inkey$
loop until k$=chr$(27)

But you mention a sensitive area, so I guess your code is more complicated than mine....Code, please?

Place the mouse cursor in the little box and start hitting on different keys. To me, it acts the save as clicking on it with the left mouse button.


Code: Select all


  Sub GetKeys (Keynumber As Integer, k As String, Rgt As Integer, _
              Lft As Integer,  cRow As Integer, cCol As Integer)
    Dim buttons As Integer         
    Keynumber=0 : Rgt=0 : Lft=0 : cRow=0 : cCol=0 
    Locate 1, 1, 0   
    Do
        GetMouse cCol, cRow,, buttons
        If buttons And 1 Then lft = 1 : Exit Sub
        If buttons And 2 Then Rgt = 1 : Exit Sub
        k = Inkey$
        Sleep 1
    Loop While k = ""
    If Asc(k) > 31 And Asc(k) < 127 Then
        keynumber = Asc(k)
    ElseIf Asc(k) = 27 Then
        keynumber = 27
    ElseIf Asc(k) = 8 Then
        keynumber = 8
    ElseIf Asc(k) = 9 Then
        keynumber = 9
    ElseIf Asc(k) = 13 Then
        keynumber = 13   
    Else
        keynumber = Cvi(k +k+ k+k) : Sleep 10     'Fm examples
    End If
   
 End Sub
 
 
Color 8, 7
For x% = 10 To 13
   Locate x%, 20 : Print Space$(20)         ' Color Mouse clicking area
Next


Do   

    GetKeys Kn%, Ky$ , Rt%, Lt%, row%, col%                                                     
   
    Color 7, 0
   
    Ke$ = UCase$(Ky$)
    If lt% <> 0  Or Ke$ <> "" Then
      If Ke$ = "B" Or (Row% > 8 And Row% < 14 And Col% > 19 And Col% < 41) Then          ' check if mouse in area
         Print " You clicked on Mouse area "
         Sleep 1000 : Locate 1, 1 : Color 7, 0 : Print Space$(30)
      Else
         Locate 20, 20
         Print "You hit the "; Ke$; " Key"
      End If
   End If
   
Loop Until Kn% = 27

follow this path

Ke$ = UCase$(Ky$)
If lt% <> 0 Or Ke$ <> "" Then
If Ke$ = "B" Or (Row% > 8 And Row% < 14 And Col% > 19 And Col% < 41) Then ' check if mouse in area
Print " You clicked on Mouse area "
Sleep 1000 : Locate 1, 1 : Color 7, 0 : Print Space$(30)
Else
Locate 20, 20
Print "You hit the "; Ke$; " Key"
End If
End If

Hi Jerry,

Row% and Col% are set regardless of the state of the mouse buttons. I think you need include the state of the mouse button in your “If Ke$ =” statement.

Hello Michael,

This is only a shorten example to show what it was doing.

Adding the Lt% to the Ke$ line does the trick, but.......

I was trying to get by with one Lt in the place of 12 Lts, since I have 12 buttons with character Hotkeys in case somebody didn't like using the Mouse.

But, it does work that way, thanks.

I coded it the same way with another compiler and it didn't cause those effects. So I thought it might be something that somebody would want to fix.

Later.......Jerry Fielden

I guess you didn't understand my post. Because of the "or", execution will always fall through. Just a little change in logic:


Code: Select all

    Ke$ = UCase$(Ky$)
    If (lt% <> 0 Or Ke$ = "B") And (Row% > 8 And Row% < 14 And Col% > 19 And Col% < 41) Then          ' check if mouse in area
         Print " You clicked on Mouse area "
         Sleep 1000 : Locate 1, 1 : Color 7, 0 : Print Space$(30)
    ElseIf Ke$ <> "" Then
         Locate 20, 20
         Print "You hit the "; Ke$; " Key"
   End If


I assumed by your example that you intended to have "B" as a mouse button key.

That works also chaos, thanks
Yeah, the B was for keyboard hits.
