如何从进程ID中查找多个窗口句柄 [英] How to find multiple window handles from a process ID

问题描述

如何查找和枚举与单个PID（进程ID）关联的所有窗口句柄，例如当程序使用单个进程中的多个窗口时。



我的尝试：



我发布了我认为这个问题的答案（为了Code Project社区的利益） ）。请随意发布更好的答案。

How can one find and enumerate all window handles associated with a single PID (Process ID), for example when a program uses multiple windows from a single process.

推荐答案

以下代码定位每个给定PID的所有窗口的句柄。

The following code locates the handles of all windows per a given PID.

void GetAllWindowsFromProcessID(DWORD dwProcessID, std::vector <HWND> &vhWnds)
{
    // find all hWnds (vhWnds) associated with a process id (dwProcessID)
    HWND hCurWnd = NULL;
    do
    {
        hCurWnd = FindWindowEx(NULL, hCurWnd, NULL, NULL);
        DWORD dwProcessID = 0;
        GetWindowThreadProcessId(hCurWnd, &dwProcessID);
        if (dwProcessID == dwProcessID)
        {
            vhWnds.push_back(hCurWnd);  // add the found hCurWnd to the vector
            wprintf(L"Found hWnd %d\n", hCurWnd);
        }
    }
    while (hCurWnd != NULL);
}

上面的代码与函数内main和local变量传递给函数的参数具有相同的名称。

即DWORD dwProcessID = 0;



将导致它枚举所有进程中的所有窗口。



将局部变量名更改为其他名称，并在GetWindowThreadProcessId（）函数和比较中使用它。

The above code has the same name for both parameter passed to the function from main and local variable inside the function.
i.e. DWORD dwProcessID = 0;

which will cause it to enumerate all the windows from all the processes.

change the local variable name to something else and use that in GetWindowThreadProcessId() function and comparison too.
