昨天同事问到，delphi里exe文件如何传递参数？

因为手头装了Delphi,PowerBuilder

以下就是代码：

Delphi:

procedure TForm1.FormCreate(Sender: TObject);
var
  i: Integer;
begin
  for i:= to ParamCount  do
  begin
    if LowerCase(ParamStr(i)) = 'beep' then
      Application.MessageBox('Demo','beep',IDOK )
   else if LowerCase(ParamStr(i))='exit' then
      Application.Terminate;
  end;
end;

PowerBuilder:

string ls_cmd, ls_arg[]

integer i, li_argcnt

// Get the arguments and strip blanks
// from start and end of string
ls_cmd = Trim(CommandParm())

li_argcnt =
DO WHILE Len(ls_cmd) > 

// Find the first blank
i = Pos( ls_cmd, " ")

// If no blanks (only one argument),
// set i to point to the hypothetical character
// after the end of the string
if i =  then i = Len(ls_cmd) + 

// Assign the arg to the argument array.
// Number of chars copied is one less than the
// position of the space found with Pos
ls_arg[li_argcnt] = Left(ls_cmd, i - )

// Increment the argument count for the next loop
li_argcnt = li_argcnt + 

// Remove the argument from the string
// so the next argument becomes first
ls_cmd = Replace(ls_cmd, , i, "")

LOOP

使用：

*.exe beep exit
