delphi中最小化其他程序及所有程序最小化（使用 shell.minimizeAll 和自己寻找窗口这两种办法）

Posted 2020-09-10 朝闻道

1.所有程序最小化

 

uses ComObj;

 

var

   shell : OleVariant;

begin

 

   shell := CreateOleObject(‘Shell.Application‘);

  shell.minimizeAll;

end;

2.最小化其他程序

spy++ 查找要最小化的程序classname

var  
  Indicador :Integer;
begin 
  // Find the window by Classname
  Indicador := FindWindow(PChar(‘notepad‘), nil);
  // if finded
  if (Indicador <> 0) then begin
    // Minimize
    ShowWindow(Indicador,SW_MINIMIZE);
  end;
end;

3.根据程序标题最小化程序

function FindWindowByTitle(WindowTitle: string): Hwnd;
    var
      NextHandle: Hwnd;
      NextTitle: array[0..260] of char;
begin
      // Get the first window
      NextHandle := GetWindow(Application.Handle, GW_HWNDFIRST);
      while NextHandle > 0 do
      begin
        // retrieve its text
        GetWindowText(NextHandle, NextTitle, 255);
        if Pos(WindowTitle, StrPas(NextTitle)) <> 0 then
        begin
          Result := NextHandle;
          Exit;
        end
        else
          // Get the next window
          NextHandle := GetWindow(NextHandle, GW_HWNDNEXT);
      end;
      Result := 0;
end;

procedure hideExWindow()
var Indicador:Hwnd;
begin
    // Find the window by Classname
    Indicador := FindWindowByTitle(‘MyApp‘); 
    // if finded
    if (Indicador <> 0) then
    begin
        // Minimize
        ShowWindow(Indicador,SW_HIDE); //SW_MINIMIZE
    end;
end;
