How can I accept parameters (for example 4 integers and a string) in my exe when its called?  I want the exe to be able to use the parameters in the main form when the form loads.  D3.
 
              Thank you

use ParamStr(1), ParamStr(2) ...

for example write this code in form's OnCreate event:

var
  i: Integer;
begin
  for i:= 1 to ParamCount do
    Memo1.Lines.Add(ParamStr(i));
end;

This will display all parameters in a Memo

Or try this:

var
  MyInt1, MyInt2, MyInt3, MyInt4:   Integer ;
  MyString: String ;

procedure MyForm.Create(Sender: TObject);
begin
// check if there are the required params
  if ParamCount = 6 then
  begin
// populate your variables
    MyInt1 := StrToInt(ParamStr(1)) ;
    MyInt2 := StrToInt(ParamStr(2)) ;
    MyInt3 := StrToInt(ParamStr(3)) ;
    MyInt4 := StrToInt(ParamStr(4)) ;
    MyString := ParamStr(5) ;
  end
  else
// can close the app which would prevent the app from being run without the run params, or you can just ignore and put default values into your variables
    Application.Terminate ;
end;

Remember...

ParamStr(0) hold your application Path and and name(ie. c:\program files\MyApp.exe)

And now for a little explanation of this code :-) :

Your program can get passed command-line parameters, these are separated by spaces. To make a string with spaces in it appear as a single parameter, put "" around it.
You can access the number of parameters passed through the ParamCount function, and you can get the separate parameters as strings using ParamCount(<Number>);
To convert these to integers, you can use the StrToInt() function.

You can use ParamStr(x) and
ParamCount
Remember as said above space count as seperate parameters.
So long file names send by explorer will be a lot of paramters.
Secondly all parameters passes are strings so you would have to know that for eg the first parameter is always a integer. Or what you can do is send a code with each parameter that tells your program what the type should be.
eg
I=integer  I234
$=String   $Hullo_World
