首先，为SystemWindow类增加了CopyData方法，向指定窗口发送WM_COPYDATA命令时代码更加简洁。其次，能够接收WM_COPYDATA命令，方便与其他程序交互。 First, the CopyData method was added to the SystemWindow class, making the code more concise when sending the WM_COPYDATA command to a specified window. Second, it can now receive the WM_COPYDATA command, facilitating interaction with other programs. 参考代码，Reference code Code:action.Window.CopyData(4194305, `::copydata ${new CopyDataProgram().HWnd.ToInt32()}, "sp.StoreString('xyCurrentPath','<curpath>');\0";`);
// sp.WindowFromClassOrTitle("ThunderRT6FormDC", "").CopyData(4194305, `::copydata ${new CopyDataProgram().HWnd.ToInt32()}, "sp.StoreString('xyCurrentPath','<curpath>');sp.StoreString('xySelectedFiles','<selitems |>');\0";`);
sp.Sleep(30);
const xyCurrentPath = sp.GetStoredString("xyCurrentPath");
上述代码直接获取XYplorer的当前路径，其中"new CopyDataProgram().HWnd"为插件接收WM_COPYDATA命令时的句柄 The above code directly retrieves the current path of XYplorer. The "new CopyDataProgram().HWnd" is the handle for receiving the WM_COPYDATA command in the plugin. Code:action.Window.CopyData(0x44646557, "[CmdDuplicateInNewWindow]\0");
向当前SumatraPDF窗口发送CmdDuplicateInNewWindow命令 Send the "CmdDuplicateInNewWindow" command to the current SumatraPDF window. Code:action.Window.CopyData(0x44646557, "[CmdCopyFilePath]\0");
sp.Sleep(10);
const filePath = clip.GetText();
获取当前SumatraPDF窗口的文件路径 Get the file path of the current SumatraPDF window. Code:using System;
using System.Drawing;
using System.Runtime.InteropServices;
using System.Text;
using System.Windows.Forms;
using System.Threading;
using StrokesPlus.net;
using StrokesPlus.net.Code;
namespace CopyDataExtensions
{
public static class SystemWindowExtensions
{
private const uint WM_COPYDATA = 0x4A;
[DllImport("user32.dll", CharSet = CharSet.Unicode)]
internal static extern IntPtr SendMessage(HandleRef hWnd, uint Msg, IntPtr wParam, ref WinAPIFunctions.COPYDATASTRUCT lParam);
public static IntPtr CopyData(this SystemWindow wnd, long dwData, string str)
{
int len = Encoding.Unicode.GetByteCount(str);
var copydatastruct = new WinAPIFunctions.COPYDATASTRUCT
{
dwData = (IntPtr)dwData,
cbData = len + 1,
lpData = str
};
return SendMessage(new HandleRef(wnd, wnd.HWnd), WM_COPYDATA, IntPtr.Zero, ref copydatastruct);
}
}
public class CopyDataProgram : Form
{
private const uint WM_COPYDATA = 0x4A;
[DllImport("user32.dll", CharSet = CharSet.Unicode)]
private static extern IntPtr FindWindowEx(IntPtr parentHandle, IntPtr childAfter, string className, string windowTitle);
[DllImport("user32.dll", CharSet = CharSet.Unicode)]
internal static extern IntPtr SendMessage(IntPtr hWnd, uint Msg, IntPtr wParam, ref WinAPIFunctions.COPYDATASTRUCT lParam);
public static IntPtr SendScript(string str)
{
int len = Encoding.Unicode.GetByteCount(str);
var copydatastruct = new WinAPIFunctions.COPYDATASTRUCT
{
dwData = (IntPtr)100,
cbData = len + 1,
lpData = str
};
IntPtr programHWnd = FindWindowEx(IntPtr.Zero, IntPtr.Zero, null, "StrokesPlus.net Gesture Surface");
return SendMessage(programHWnd, WM_COPYDATA, IntPtr.Zero, ref copydatastruct);
}
public IntPtr HWnd
{
get
{
return this.Handle;
}
}
protected override void WndProc(ref Message m)
{
if (m.Msg == WM_COPYDATA)
{
var copydatastruct = (WinAPIFunctions.COPYDATASTRUCT)m.GetLParam(typeof(WinAPIFunctions.COPYDATASTRUCT));
int dwData = copydatastruct.dwData.ToInt32();
string lpData = copydatastruct.lpData;
if (dwData >= 4194304 && dwData <= 4194307)
{
lpData = lpData.Replace("\\", "\\\\"); // XYplorer path conversion
}
SendScript(lpData);
}
base.WndProc(ref m);
}
}
}
以上为插件代码，将上述代码另外为cs文件，例如C:\CopyData.cs，利用如下命令编译 To compile the above code as a separate cs file, for example C:\CopyData.cs, you can use the following command: Code:C:\Windows\Microsoft.NET\Framework64\v4.0.30319\csc.exe /target:library /out:C:\CopyData.dll /reference:"C:\Program Files\StrokesPlus\StrokesPlus.net.exe" C:\CopyData.cs
命令将代码C:\CopyData.cs编译为插件C:\CopyData.dll，csc.exe为.net编译器，/reference参数指定为StrokesPlus.net.exe的路径 The command compiles the code C:\CopyData.cs into the plugin C:\CopyData.dll. The csc.exe is the .NET compiler, and the /reference parameter specifies the path to StrokesPlus.net.exe.
