在另一个应用程序点击一个按钮 [英] Click a button in another application

问题描述

我想哟使用 SendMessage函数或 PostMessage的在另一个应用程序按一个按钮

I want yo use SendMessage or PostMessage to press a button in another app

我有一个示例代码通过获取窗口句柄要做到这一点，但它不能正常工作

i have a sample code to do this by getting Window Handle, but it doesn't work

此外，我使用了WinDowse来获得所需的信息。这里是代码

also i used "WinDowse" to get required info. here is the code

private const uint BM_CLICK = 0x00F5;
private const uint WM_LBUTTONDOWN = 0x0201;
private const uint WM_LBUTTONUP = 0x0202;

private void PushOKButton(IntPtr ptrWindow)
{
    WindowHandle = FindWindow(null, "Form1"); 
    if (ptrWindow == IntPtr.Zero)
      return;

    IntPtr ptrOKButton = FindWindowEx(ptrWindow, IntPtr.Zero, "Button", "&Yes");

    if (ptrOKButton == IntPtr.Zero)
      return;

    SendMessage(ptrOKButton, WM_LBUTTONDOWN, 0, 0);
    SendMessage(ptrOKButton, WM_LBUTTONUP, 0, 0);
    SendMessage(ptrOKButton, BM_CLICK, 0, 0);
}

有一个Compelete Suloution在C＃？

is There a Compelete Suloution in c# ?

推荐答案

您有正确的总体思路。
总有一些技巧，以自动化。

You have the right general idea. There are always tricks to automation.

按钮下/上是preatty接近点击的原始作用，但并不完全一样。
你将要考虑

Button Down/Up is preatty close to the raw action of clicking, but not quite the same. You will want to consider

1. 的COORDS在那里你点击 - 某些按钮在0,0不喜欢边点击


2. 鼠标的位置 - 鼠标在开始或结束按钮以外会导致其无法正常工作


3. 时间点击 - 有时一个快速的点击是忽视，加比如说为10ms

BM_CLICK是做一个按钮鼠标点击时发送一个额外的Win32消息 - 它是简短的表达方式，更容易，如果控制是单独使用此权利类型。

BM_Click is an extra win32 message that is sent when doing a mouse click on a button - it's the shorter method and easier if the controls are the right type to use this alone.

一些努力，以防止一些像从国外的应用程序密码编辑使用WM_GETTEXT，警惕你可能还取​​决于目的地的应用程序的问题。

Some effort is made to prevent things like using WM_GetText on password edits from foreign apps, be wary you may also have issues depending on the destination app.

不幸的是我对你没有C＃示例代码现在。

Unfortunately I have no C# sample code for you right now.

也许你会考虑的AutoIt 以节省一些时间。
