Well, I have had past experiences programming in C#, and I'm taking on Delphi now.

What I would like to know is how to extract information from a Text Box.

In C#, it would be something like

Code:

string a = textBox1.Text;


And I understand that in Delphi I would have to do something like

Code:

procedure whatever
var
  string a;
begin
  a := RichEdit1.Text
end;
end.


Or something, but it gives me an error when I do that. I have searched many websites to try to figure this out, but all searches have come up empty. Could someone help?

Err, it said something like "Undeclared identifier a", and "Identifier expected, but A found".

But by changing it to

Code:

a : string;


It worked.

~~

Note to self, Delphi and C are VERY different. x-x

Edit:

Getting another error when I try:

Code:

procedure whatever
var
  a : string;
begin
  a := 'Hehe Waffles';
  if (RichEdit1 <> a)
  then ShowMessage('d00d');
end;
end.


It says that STRING and TRICHEDIT are incompatible types.

Thank you very much! Though it seems like a bit of a careless mistake on my part. Oh well :roll:
