问题描述

我尝试获取所有已启动Windows的可执行文件名称,而我的问题是:

I try to get the name of executable name of all of my launched windows and my problem is that:

我使用了方法

UINT GetWindowModuleFileName(      
HWND hwnd,
LPTSTR lpszFileName,
UINT cchFileNameMax);

我不明白为什么它不起作用。

And I don't understand why it doesn't work.

关于窗口的数据是:
-HWND和PROCESSID

Data which I have about a window are:
-HWND AND PROCESSID

错误是:
例如:

The error is: e.g:

HWND: 00170628 
ProcessId: 2336        
WindowTitle: C:\test.cpp - Notepad++
GetWindowModuleFileName():  C:\test.exe

HWND: 00172138 
ProcessId: 2543        
WindowTitle: Firefox
GetWindowModuleFileName():  C:\test.exe

HWND: 00120358 
ProcessId: 2436        
WindowTitle: Mozilla Thunderbird
GetWindowModuleFileName():  C:\test.exe

注意:test.exe是我的可执行文件的名称,但不是Notepad ++的完整路径...这也是Mozilla Thunderbird的...我不明白为什么

Note: test.exe is the name of my executable file, but it is not the fullpath of Notepad++... and it make this for Mozilla Thunderbird too... I don't understand why

我使用这样的功能:

char filenameBuffer[4000];
if (GetWindowModuleFileName(hWnd, filenameBuffer, 4000) > 0)
{
    std::cout << "GetWindowModuleFileName(): " << filenameBuffer << std::endl;
}

感谢您的回复。

推荐答案

GetWindowModuleFileName 函数仅在当前进程中适用于Windows。

The GetWindowModuleFileName function works for windows in the current process only.

您必须执行以下操作:


  1. 使用 GetWindowThreadProcessId

  2. 使用PROCESS_QUERY_INFORMATION 和 PROCESS_VM_READ 访问权限打开进程。 microsoft.com/zh-CN/windows/win32/api/processthreadsapi/nf-processthreadsapi-openprocess rel = nofollow noreferrer> OpenProcess

  3. 使用在处理句柄上的 GetModuleFileNameEx

  1. Retrieve the window's process with GetWindowThreadProcessId.
  2. Open the process with PROCESS_QUERY_INFORMATION and PROCESS_VM_READ access rights using OpenProcess.
  3. Use GetModuleFileNameEx on the process handle.

如果您确实要获取注册了窗口的模块的名称(而不是进程可执行文件),则可以使用 GetWindowLongPtr GWLP_HINSTANCE 。然后可以将模块句柄传递给前面提到的 GetModuleFileNameEx

If you really want to obtain the name of the module with which the window is registered (as opposed to the process executable), you can obtain the module handle with GetWindowLongPtr with GWLP_HINSTANCE. The module handle can then be passed to the aforementioned GetModuleFileNameEx.

TCHAR buffer[MAX_PATH] = {0};
DWORD dwProcId = 0; 

GetWindowThreadProcessId(hWnd, &dwProcId);   

HANDLE hProc = OpenProcess(PROCESS_QUERY_INFORMATION | PROCESS_VM_READ , FALSE, dwProcId);    
GetModuleFileName((HMODULE)hProc, buffer, MAX_PATH);
CloseHandle(hProc);
