show a pointer, not what the pointer points to

Try casting it as a Longint:

        n := Longint(p);

I expect that Delphi will permit this typecast.  Notice the omission of
a "^" in the above statement.

Re:show a pointer, not what the pointer points to


Can someone tell me how I can showmessage the what is inside a Pointer
variable, (show the address as string), but not show what a pointer points
to?

tks.

{uses SysUtils }
ShowMessage(Format('%0.8x', [INTEGER(YourPointer)]));
or
ShowMessage(IntToHex(INTEGER(YourPointer),8));

Sure, typecast it as an integer:

  ShowMessage(IntToStr(Integer(MyPointer)));

Alternatively the Format() routine has the "%p" parameter that formats
a pointer as a string.

Format('%p', [pointer]);  // = 8 character address
