Delphi 获取句柄 sendmessage
查找另外一个窗口的句柄： handle := FindWindow(nil,PChar('窗口的标题'));//查到窗体句柄
查找子窗体：childHandle := FindWindowEx(handle,0,'子窗体类','子窗体标题');
另外有个枚举子窗体的API，EnumChildWindows(主创体句柄,@回调函数,用户参数);
用这个函数需要自己写一个回调的函数，比如：
function EnumChildProc(ahWND:HWND; param:LPARAM):boolean; stdcall;
sendmessage(handle,message,wl,rl)
unit Unit1;
interface
uses Windows, Messages,Tlhelp32, SysUtils, Classes, Graphics, Controls, Forms, Dialogs, StdCtrls;
type
TForm1 = class(TForm)
procedure FormCreate(Sender: TObject);
private
{ Private declarations }
public
{ Public declarations }
end;
var Form1: TForm1;
implementation
{$R *.DFM}
procedure TForm1.FormCreate(Sender: TObject);
var a,b:PAnsiChar;
h:HWND;
begin
h:= FindWindow(nil,'abc.txt -

技术交流,DH讲解. 最近和肥鸟交流了下关于字符串方面的知识,而这篇文章是很久以前写的,现在发出来吧. 我们写两段代码来对比下:
第一个用Copy函数:
procedure TForm1.Button1Click(Sender: TObject);
var
a,c:Cardinal;
n:Integer;
D:Double;
i:Integer;
b:string;
begin
c:=0; ......
类的事件
unit Unit1;
interface
uses
Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
Dialogs, StdCtrls;
type
TMyEvent = procedure of object; //不带参数的过程
TMyEventExt = procedure(AName: string) of object; //带参数的过程
TForm1 = class(TForm)
......
