Prevent native windows popup?

[telmob]

Hello again.

I'm (still) making a program to prevent new apps to run, based on Software Restriction Policy.

However, when SRP is set, the new apps show a native windows popup saying the file was not found.

I know i can hide it when it shows, but is there a way to prevent it from showing or even to change its contents in a 'natural' way? Do i need a DLL for this?

Why do you want to prevent the popup?

The user tries to start a program he isn't allowed to and I think he should know so he doesn't try it again.

Because i want to replace it with a custom tray popup in a non-intrusive way.

So when the user tries to open any file blocked, instead of having a popup saying the file is missing (which is inaccurate) a simple popup will rise saying an application was prevented from running.

We don't use SRP here. Can you please post a screenshot of such a popup so we know how it looks like?

[telmob]

Well... i made a mistake. This popup is different from other solutions.

But still, i'd like to prevent it from showing.

Attached.

Get the ControlID of the "OK" button using the Window Info Tool which comes with AutoIt. Then click away the window:

$ControlID = xx
While 1
  $hWindow = WinWait("", "blocked by group policy")
  ControlClick($hWindow, "", $ControlID)
   ; Display your message here
WEnd

Is this the supposed ControlID? [CLASS:Button: INSTANCE:1]

I can't use it, keep getting a syntax error.

How do you use it? Can you post your code?

[telmob]

Here it is:

$ControlID = [CLASS:Button: INSTANCE:1]
While 1
  $hWindow = WinWait("", "blocked by group policy")
  ControlClick($hWindow, "", $ControlID)
   ; Display your message here
WEnd

Also tried using something simillar to ControlClick example in the help file but couldn't use it as well.

Try:

$ControlID = "[CLASS:Button; INSTANCE:1]"
While 1
    $hWindow = WinWait("", "blocked by group policy")
    ControlClick($hWindow, "", $ControlID)
    ; Display your message here
WEnd

Not working. The program keeps running and doesn't recognize the window.

I think the problem is lying in the window title, which is variable. Not sure though.

$ControlID = "[CLASS:Button; INSTANCE:1]"
While 1
    $hWindow = WinWait("", "This program is blocked by group policy.")
    ControlClick($hWindow, "", $ControlID)
    MsgBox("","","App Blocked")
WEnd

If you use the Window Info Tool, select the Summary tab and move the crosshair over the window, do you see the text "This program is blocked by group policy." listed under ">>>> Visible Text <<<<"?

[telmob]

No, just 'OK'.

Any way to 'grab' the popup window without from the 'OK'?

I don't to grab all the 'OK' windows or it'll grab a bunch

I'm sorry to be bumping this thread, but i would really like to have this feature in my app.

Is there any way i can prevent this native windows popup from showing?
