SendKeys in Delphi 2010

Question

Hi I\'m trying to do the classic SendKeys (\'hello world\'); was done in visual basic delphi but I discovered that you can not do that.

Does anyone know

Answer 1

Here are some of the functions I've assembled to use in some automation projects I had to do in past. They utilize keybd_event() API.

procedure SendKeys(const AString: String; const AAmount: Integer = 1);
const
  TReadableChars = [32..126];
  TShiftChars    = [33..43, 58, 60, 62..90, 94..95, 123..126];
type
  TKeyInfo = record
               AsChar  : Char;
               AsOrd   : Integer;
               VK      : Integer;
               SC      : Integer;
               UseShift: Boolean;
             end;
  TKeys    = TList;
var
  key   : TKeyInfo;
  keys  : TKeys;
  C1, C2: Integer;
begin
  keys := TKeys.Create;
  try
    for C1 := 1 to Length(AString) do
    begin
      key.AsChar := AString[C1];
      key.AsOrd := Ord(key.AsChar);

      if key.AsOrd in TReadableChars then
      begin
        key.VK := VkKeyScan(key.AsChar);
        key.UseShift := key.AsOrd in TShiftChars;
        key.SC := MapVirtualKey(key.VK, 0);
        keys.Add(key);
      end;
    end;

    for C1 := 1 to AAmount do
      for C2 := 0 to keys.Count - 1 do
      begin
        key := keys[C2];

        if key.UseShift then
          keybd_event(VK_SHIFT, 0, 0, 0);

        keybd_event(key.VK, key.SC, 0, 0);
        keybd_event(key.VK, key.SC, KEYEVENTF_KEYUP, 0);

        if key.UseShift then
          keybd_event(VK_SHIFT, 0, KEYEVENTF_KEYUP, 0);
      end;
  finally
    keys.Free;
  end;
end;

procedure SendKey(const AVKCode: Integer; const AAmount: Integer = 1);
var
  C1: Integer;
begin
  for C1 := 1 to AAmount do
  begin
    keybd_event(AVKCode, 0, 0, 0);
    keybd_event(AVKCode, 0, KEYEVENTF_KEYUP, 0);
  end;
end;
