Can't access to "Yes" button with UIAccessor

[andres.hernandezB63FL]

Hi!
I'm having a problem with a dialog that comes up in certain situations when using re scale tool from Time Configuration. Since re scale functionality is not accessible directly through MaxScript I had to access to it using UIAccessor. 
I need to click always on "Yes" in this window. I used UIAccessor.PressDefaultButton() and it works, however if the user is working in a different window than 3ds Max (for example, is doing something in windows Explorer) it will do "Enter" in those cases and it can be risky and not expected, that's why I'm digging into a solution to hit only "Yes" button for this window. 

if theDialogName != undefined and matchpattern theDialogName pattern:"*Biped*" then 
(
  UIAccessor.PressButtonByName WindowHandle "Yes"
)

If I print inside this condition theDialogName it returns "Biped" so I know I'm in the correct window. 
And here is the pop up window 

 Hope someone can help me with this. Any advice or tip is very appreciated. 
Thanks

Since there's an underline in the Yes button representing a mnemonic key denoted by ampersand, I'd first try pressing "&Yes" button instead of "Yes" button.

Hi Vojtěch, thank you for taking the time answer. I had my hopes on that but I tried and no, is not pressing the button 😕 
Do you have any other idea that I can try? 

[Swordslayer]

And pressing the button by its handle (hwnd)? It's the first child of the dialog (you can make sure by checking the resource ID, it's 6 for this button).

[andres.hernandezB63FL]

Thank you Vojtěch.
I have no idea how to do that, are you talking about something like this?:

hwnd = windows.getChildHWND 0 WindowHandle
windows.sendMessage hwnd[6] WM_LBUTTONDOWN 0 0

This will return:
-- Unable to convert: 530346P to type: String
 I tried iterating over the children of the windowHandle but it returns nothing with this loop:

for i in (windows.getChildrenHWND WindowHandle) do print i

Thank you for your help, and sorry that I'm completely lost with this

do you use the DialogMonitorOPS?

[denisT.MaxDoctor · Accepted solution]

did you try to press the "Yes" button by its standard default ID:

UIAccessor.SendMessageID <HWND> #IDYES

where <HWND> is the dialog's hwnd of course.

Actually, that's not true... You can scale the scene time through MXS. What exactly do you want to do? How do you want to scale?

[trykle]

This is a QT window `Qt5151QWindowIcon` and you cannot obtain the handle of the button. You may want to send an `Enter` key (Be sure to focus on the `Yes` button).

[trykle]

Or use: `SetQuietMode true`

Yes, that's a good point. This "Biped" dialog is a QMessageBox.
Therefore, its buttons must be clicked according to Qt methods. Win32 methods are not suitable for it.

However, it is still possible to capture it using DialogMonitorOPS, and "click" its "Yes" button.

Hi Denis and trykleqq thank you for your help. 
I tried your solution Denis and it seems to work perfectly. I'm using DialogMonitorOPS
I'm trying to rescale the scene time and I research about accessing to that functionality through MXS but it wasn't possible, are you aware of any other solution for this? I'm interested. 
About what trykleqq suggested, how can you set "focus on" when you are working with UIAccessor? also the `SetQuietMode true` sounds even better, I never tried that before, thank you for the suggestion.
Thanks a lot for your help, I really appreciate it

1.

you can always scale all scene keys by something like:

scaletime objects animationrange 0.75

as well as move all keys anywhere

2.
using Quiet Mode was the first thing that came to my mind, but it always uses the #default option for the requested cases. In the case of "negative biped keys", I'm not sure if the "YES" option is always the default, and there is no place or way to change the default to "NO". So I can't consider it safe, as I can't be sure of the current #default option.

In general, of course, "Re-scale Time" is a much more complex method than scaletime, but for something simple the (movekeys + scaletime) might work.

Thank you Denis, I'll give a try to this because I'm also having some issues with re-scale tool because is not keeping whole frames even with the checkbox active so maybe this could help. 
Thanks a lot!
