[Solved] Specifying a ControlID Using a Partial String

[Zohar]

Hi

I need to use ControlGetPos() on VLC's Video Output control.
This control's class is named differently each run of VLC:
On one run it may be "VLC video output 02E20328"
and on the second     "VLC video output 02D56114"

So the only known part is the beginning: "VLC video output ".

Is it possible somehow to reference a Control with a partial Class name?

Thank you

Use REGEXPCLASS:

ControlGetPos("Title", "", "[REGEXPCLASS:(?i)VLC Video Output.*]")

Hi FrancescoDiMuro

Thank you very much.

I am curious to ask:
What does the "(?i)" before the string mean?
And also, why in the end there's a "." before the *?

Thank you

@Zohar

The "i" at the start of the string is called a modifier, and it tells to the RegEx engine:

"Don't care about capitalization; threat VLC and vlc (and all the other possible combinations) in the same manner.

The ".*" at the end of the string, instead, is a metacharacter (the dot), and a quantifier (the asterisk), and they tell to the RegEx:

"After matching VLC Video Output, there could be 0 to N character (every character) after that string", so you don't need to worry about what does follow the string, but just be secure that VLC Video Output is in the string

Terrific, thank you so much.

I am using it, and it works.

I am also curious to ask,
If I ever want to get the Control's Name as string, and hold it in a variable,
Is there a way to List the controls that are on a Window (specified by a Window Handle)?

You can use WindowGetClassList(), which returns a list of all the classes related to a Window.

Here it is an example
