Disabling controls on another program?

[XinMan]

Hello,

I am trying to find a way to disable controls on a program that I didn't write and have no control over. How would I be able to disable such things as buttons or something like that?

I know this probably doesn't make since so if it doesn't then e-mail me at [email protected]

TIA,
XinMan

Can you tell us what program you're trying to disable the button for? It's not hard to do it. You would have to use FindWindowEx API to find the application you need, then using the same API, find the control on it. Then using EnableWindow API to disable the control.

Yeah...this sounds interesting...I wouldn't mind knowing about this sorta thing.

How about some simple examples (A couple of articles, John Percival? )...

How would you disable the equals button in the Windows Calculator (calc.exe) ?

Or add another menu item to the help menu (like a web link, or that might call my own bit of code) ?

Or how would you change the Title Bar caption ?

Yeah... a decent VB World atricle would be cool, now I come to think of it...

Just like the 'Ok' button / 'apply' button on some of the settings menus in Windows.

No, I am not trying to disable the netzero ads. I'm trying to disable something in Windows, for security reasons. This way people can't change the settings unless the Site Administrator changes them.

Thanks,

So what is the application name you're trying to disable the button for?

Private Declare Function EnableWindow Lib "user32" (ByVal hwnd As Long, ByVal fEnable As Long) As Long
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 Sub Command1_Click()
    Dim hCalc As Long
    hCalc = FindWindowEx(FindWindow("SciCalc", "Calculator"), 0&, "Button", vbNullString)
    EnableWindow hCalc, 0
End Sub

disables the mc button!

use

EnableWindow hCalc, 1

to enable it

also for title captions:
