Question

是否可以使用其他进程的窗口进行某些操作？我想做的是： - 删除窗户装饰 - 将窗口移动到屏幕的任何位置 -let窗口保持在顶部而不是模态

指向命令行工具，脚本或C / C ++代码段的链接非常棒。

非常感谢！

我决定再试一次，所以我尝试了你的代码，并添加了遗漏的内容：-naked选项。

删除装饰came from here的关键。虽然它有效，但你最终会发现裸体应用程序可能会在它之后显示一些错误。

享受：

#include <iostream>
#include <string>
#include <sstream>
#include <algorithm>
#include <limits>

    #undef min

int main(int argc, char* argv[])
{
  char** param = argv;

  unsigned int x = numeric_limits<int>::min(), y=numeric_limits<int>::min(), w=numeric_limits<int>::min(), h=numeric_limits<int>::min();
  HWND z = HWND_NOTOPMOST;
  unsigned int flags = (SWP_SHOWWINDOW | SWP_NOSIZE | SWP_NOMOVE | SWP_NOZORDER);

      if (!*param) break;

      sparam = *param;

删除窗口装饰有点棘手。我猜你可能要为你的问题设置赏金。

检查Windows API以查看您应该拨打的功能。

无论如何，这个片段应该让你开始：

HWND win_handle = FindWindow (0, "Title Of The Window");    
if (win_handle != 0)
{
    /* Do your magic */

    // MoveWindow params: handle, x=100, y=200, width=400, height=450, repaint
    MoveWindow(win_handle, 100, 200, 400, 450, TRUE); 

}
else
{
    std::cout << "!!! FindWindow failed" << std::endl;
}

最后，在karlphillip的帮助下，我能够编写一个移动，调整大小并将窗口固定在顶部的工具。我缺少的是如何去除装饰和关闭。这是代码：

#include "windows.h"
#include <iostream>
#include <string>
#include <sstream>
#include <algorithm>
#include <limits>
using namespace std;

#ifdef min
  #undef min
#endif

int main(int argc, char* argv[])
{
  char **param= argv;
  wstring winTitle;
  bool close = false;
  unsigned int x=numeric_limits<int>::min(), y=numeric_limits<int>::min(), w=numeric_limits<int>::min(), h=numeric_limits<int>::min();
  HWND z=HWND_NOTOPMOST;
  unsigned int flags=SWP_SHOWWINDOW | SWP_NOSIZE | SWP_NOMOVE | SWP_NOZORDER;
  ++param;
  while ( *param )
  {
    string sparam(*param);
    if ( sparam == "-title" )
    {
      ++param; if (!*param) break;
      sparam =*param;
      winTitle.resize(sparam.size());
      copy (sparam.begin(), sparam.end(), winTitle.begin());
    }
    else if ( sparam == "-move" )
    {
      ++param; if (!*param) break;
      sparam =*param;
      stringstream sstr( sparam );
      char sep;
      sstr >> x >>sep >> y;
      if ( x != numeric_limits<int>::min() && y != numeric_limits<int>::min() )
      {
        flags &= ~SWP_NOMOVE;
      }
    }

    else if ( sparam == "-resize" )
    {
      ++param; if (!*param) break;
      sparam =*param;
      stringstream sstr( sparam );
      char sep;
      sstr >> w >>sep >> h;
      if ( h != numeric_limits<int>::min() && w != numeric_limits<int>::min() )
      {
        flags &= ~SWP_NOSIZE;
      }
    }

    else if ( sparam == "-top" )
    {
      z = HWND_TOP;
      flags &= ~SWP_NOZORDER;
    }

    else if ( sparam == "-staytop" )
    {
      z = HWND_TOPMOST;
      flags &= ~SWP_NOZORDER;
    }

    else if ( sparam == "-bottom" )
    {
      z = HWND_BOTTOM;
      flags &= ~SWP_NOZORDER;
    }

    else if ( sparam == "-hide" )
    {
      flags |= SWP_HIDEWINDOW;
    }

    else if ( sparam == "-close" )
    {
      close=true;
    }

    ++param;      
  }
  if ( winTitle.empty() )
  {
    return 1;
  }

  HWND win_handle = FindWindow (0, winTitle.c_str());    
  if (win_handle != 0)
  {

     if(close)
     {
      TerminateProcess( (HANDLE )GetProcessId( win_handle ), 0 );
      return 0;
     }

     SetWindowPos( win_handle, z, x, y, w, h, flags );
  }
  else
  {
      cout << "!!! FindWindow failed" << endl;
  }

  //system("pause");
    return 0;
}
