First off, its kinda senseless to post only compiled code since we can't help you by seeing that.. I ran it, my machine hasn't blown up yet, but learned nothing about your project.. Alot of ppl will refuse to launch your exe out of fear..
As for your question, there are a few options.. Some are elegant like "subclassing" the control (search that on this site) or by applying something like in the included project.. If simplicity and halfass workarounds are sufficient though, consider reprogramming the 1st app to watch a file that the other app can create/write to..

thanks..

but it doesn't work ...

i thing the hwnd can help ...
but i don't know how ?
thanks

Scour the site for subclassing examples.. Most ppl don't write their own subclassing code because its really complex.. Alot of ppl need it though, and usually there is a pre-made version of 'almost' what you need..
Hey, another option that might be applicable isn't vb related at all.. There is a great little/powerful scripting language called AutoIt.. For alot of purposes involving subclassing type needs its by far the easiest solution since thats pretty much what its made for.. Hardly any overhead programming like a fullblown language.. Its possible that you could whip up a script that compiles to an exe in a few lines/minutes.. And its free to boot.. Its on the net easy to find..

Is this other program yours?

If not, why the need to disable a button?

I've had legit reasons to do that.. Some programs can be dangerous in the hands of the computer illiterate..
The Jon Stewart Show illustrated how dangerous Outlook Express can be, in that story about the email deletion scandal..

Then end user training is necessary, not the manipulation of a third party application.

I tried that too many times.. The main app I've adultered is Simply Accounting.. Too complex for a freecell guru of a business owner..

You could always take haxxoring lessons and switch the bit that controls the enabled/disabled of the required button in the compiled source code...that's how most hackers get around security in programs :-P

However, this isn't the forum to discuss that, manipulation of any third party software is illegal and even if it was your own code people would say rewrite it or do it in the source :-P

here is an example to get you started.

'this example requires 2 command buttons, command1 and command2

Option Explicit

Private Declare Function EnableWindow Lib "user32" (ByVal hwnd As Long, ByVal aBOOL As Long) As Long
Private Declare Function IsWindowEnabled Lib "user32" (ByVal hwnd As Long) As Long

Private Sub Command1_Click()

Dim CmdToEnable As Long
Dim RetVal As Long

CmdToEnable = Command2.hwnd 'put your object Handle here

RetVal = IsWindowEnabled(CmdToEnable) 'you can check to see the state

RetVal = EnableWindow(CmdToEnable, Not CBool(RetVal)) 'put true/false if you desire
'EnableWindow CmdToEnable, -1 'you can also use it as a sub
If RetVal Then
    'it worked, put code here if you wish
End If


End Sub

thanks 4 all

why i ask this question ???

coz my company .. buy a sms program but we find in it some thing strange :::

some command is disable >>> and i need to change it ti enable >> coz we buy this program

thanks

Well then you're probably only going to crash it.. Contact the company that wrote/sold it if you have a legit registration issue..

I agree with trigger...they're probably disabled with good reason. I assume you have to put in settings which affect those buttons, maybe like the SMS carrier details, and if you're enabling a button that is disabled because the SMS carrier doesn't support it, you're asking for trouble bigtime.
