封装了一些常用的api,查找窗体,查找子窗体等简易功能..不是原创,也记不清从哪弄来的了...{:soso_e128:}
操作没有保护的窗体还是可以的..{:soso_e120:}回复可见...
DOM下载地址:
记得好像有几个忘记加了. 单放在这里吧.{:soso_e113:},帖子过长,预览的部分删除了..详细请见附件..[code=csharp]
[DllImport("user32.dll")]
public static extern bool SetForegroundWindow(int hWnd); //置顶某窗体 就是让某个窗体显示窗体最前
[DllImport("user32.dll")]
private static extern int SendMessage(IntPtr hWnd, int Msg, int wParam, int lParam); //注入内容,可操作文本框啦,等等
//附带一个方法
public void InputStr(IntPtr myIntPtr, string Input)
{
byte[] ch = (ASCIIEncoding.ASCII.GetBytes(Input));
for (int i = 0; i < ch.Length; i++)
{
SendMessage(myIntPtr, WM_CHAR, int.Parse(ch.ToString()), 0);
}
}
SendKeys.Send("{TAB}"); //模拟键盘输入table
SendKeys.Send("{ENTER}"); //模拟键盘输入ENTER
[/code]
祝 :
every body 生活愉快,身体健康..{:soso_e121:}
have Fun.!
