Hello i am changing an old Excel project who are using DialogSheets.

But :
I can't modify them
I don't even know where there are. I can't find them with Macro editor. With Microsoft Script Editor i get a sorte of HTML source code, but it doesn't match to anything i think.
Design Mode isn't working.

Anyone could know where i can modify DialogSheet interfaces ?

For exemple, i get
DialogSheets("M_Welcome").Show but there are no match in my projet for M_Welcome

have a nice day
