I'm trying to set a specific character in a TCaption:
Code:
frmMain.lblWord.Caption[i] := C;

It generates error "E2064 Left side cannot be assigned to."

No. C is a character already declared... I'm trying to set the character in lblWord's caption.

caption is a property, and properties don't like reads and writes at the same time. (they either call the read function or the write procedure)

do this:
Code:

var temp: string;
...
temp:=frmMain.lblWord.Caption;
temp[i]:=C;
frmMain.lblWord.Caption := temp;

Yeah, I already knew I could just declare another string and use that... I just wanted to make sure if there wasn't something I could do to get the job done directly. Razz I'll go ahead and use it, it's not a big deal.
