Have your form change colors nicely without flickering:

VB Code:

Option Explicit
Dim r As Byte, g As Byte, b As Byte, flag As Byte, d(3) As Byte
 
Private Sub Form_Load()
    r = 255: g = 255: b = 255: flag = 0
End Sub
 
Function Disco()
 
    If flag Then
        r = DoIt(1, r)
        g = DoIt(2, g)
        b = DoIt(3, b)
        flag = flag - 1
    Else
        r = Ran(1, r)
        g = Ran(2, g)
        b = Ran(3, b)
        flag = 50
    End If
        Me.BackColor = RGB(r, g, b)
 
End Function
 
Function DoIt(ByVal a As Byte, ByVal c As Byte)
    If ((d(a) = 2 And c < 255) Or c = 0) Then
        c = c + 1
        d(a) = 2
    Else
        If ((d(a) = 1 And c) Or c = 255) Then
            c = c - 1
            d(a) = 1
        End If
                If a = 3 Then
            If (d(1) + d(2) + d(3) = 0) Then flag = 1
        End If
    End If
 
    DoIt = c
 
End Function
 
Private Sub Timer1_Timer()
Disco
End Sub
 
Function Ran(ByVal a As Byte, ByVal c As Byte)
    
    If ((Rnd > 0.667 Or c = 0) And c < 255) Then
        c = c + 1
        d(a) = 2
    ElseIf ((Rnd <= 0.5 Or c = 255) And c > 0) Then
        c = c - 1
        d(a) = 1
    Else
        d(a) = 0
    End If
 
    Ran = c
    
End Function

To Make a form Opacity fade:

VB Code:

Dim cat as string
 
Private Sub Timer2_Timer()
  Select Case cat
    Case "Up"
      x = Val(x) + 1
      If Val(x) >= 255 Then cat = "Down"
    Case "Down"
      x = Val(x) - 1
      If Val(x) <= 150 Then cat = "Up"
    Case ""
      cat = "Up"
  End Select
  Call Mache_Transparent(Me.hWnd, 0)
End Sub
 
Private Sub Form_Load()
    x = 120
cat = "Up"
End Sub

Re: Cool Effects For your Form:

i dunno how to make dlls, plus isnt it better to have it open source..then you can add it inside your form yourself without an extra dll hangin around..

--hope you got my point lol, that was kinda confusing

Re: Cool Effects For your Form:

I wish people gave Delphi a try, i mean you can alpha blend forms and do all the above with only around 8 lines of code. Especially since Delphi augments windows API meaning you dont need to declare everything.

Re: Cool Effects For your Form:

its simple, i was baffled at first but after 2 weeks i felt like a pro :) its just like if..else etc. for example:

try
Text1.Text:= 'Hello World'
except on exception do
ShowMessage('Error displaying text')
end;

the code is basically telling the compiler that if displaying Hello World fails somehow, then the messagebox error is shown. You only use Try..except..and finally for two reasons.

1) Except > is used for error handling
2) Finally > makes sure your app does the required code

Delphi includes all its uses ready for you to add, so instead of calling all the Windows API to access say, the registry. Just by adding:

Uses..Registry;

you have full access to the registry. In one line of code, pretty simple ey, production seems much more faster in Delphi too. I started out in VB like many others, and at the time i thought it was the god in RAD development. But until you actually give Delphi a weeks tryout, you dont know what your missing. You can create simple applications without the need for shipping external dll's and runtime libraries, you can choose whether to include it in the exe, thus creating a workable standalone exe on ANY computer. Simple things make a huge difference in Delphi, i mean in VB you need code or external libraries to add icons or office XP style menus right, in Delphi its done for you. Just browse and select!

Why Microsoft didnt add basic features like this i dont know, all i do know though is Delphi takes away the chores of RAD, so you can spend more time having fun with your projects.

Put it this way, i produce more and better projects in Delphi then i could of ever imagined in VB!

Re: Cool Effects For your Form:
