如何获取窗口的可执行名称 [英] How to get the Executable name of a window
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:
- 使用
GetWindowThreadProcessId
。 - 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
。 - 使用在处理句柄上的
GetModuleFileNameEx
。
- Retrieve the window's process with
GetWindowThreadProcessId
. - Open the process with
PROCESS_QUERY_INFORMATION
andPROCESS_VM_READ
access rights usingOpenProcess
. - 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
和 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);
