the Structure is defined in the Api
Code: Select all
CHARFORMAT\cbSize=SizeOf(CHARFORMAT)
Debug CHARFORMAT\cbSize
End
But why is there the errormessage that this Variable doesent have a structure?

You have to define a name for the structure, and then this name is the container for the structure's elements.
Use it this way:
Code: Select all
structureName.CHARFORMAT
structureName\cbSize=SizeOf(CHARFORMAT)
Debug structureName\cbSize
End
You tried to call structureType\element. So PB 'thinks' CHARFORMAT is a variable, that has not been declared as a pointer to a structure. So the following will work, too, though it's confusing the programmer.
Code: Select all
CHARFORMAT.CHARFORMAT
CHARFORMAT\cbSize=SizeOf(CHARFORMAT)
Debug CHARFORMAT\cbSize
End

You can check the size of a STRUCTURE this way:
It isn´t possible to read a value from a STRUCTURE !!!!
You can ONLY read a value from an ELEMENT of a structure:
Create an element of the CHARFORMAT STRUCTURE this way:
and read a value
or change a value:
I hope it helps ...

@ Froggerprogger
thanks, now its clear. I thought I have to Dim the Structure
like Dim My.CHARFORMAT(1), but that would not work in a apimessage.
@Wolfgang
It is possible and documented in the helpfiles, search for "Sizeof"
The CHARFORMAT works only, if you set the first Element cbSize to the size of the structure
Windows need this, to recognize, what RichEditVersion is used, 2.0 or 3.0
