How from an Handle can I retrieve the component name?
To retrieve the component name from a handle in Windows, you can use the GetClassName
function from the Windows API. Here's an example of how you can use it in C++:
cpp#include <Windows.h>
// Function to retrieve the component name from a handle
std::wstring GetComponentNameFromHandle(HWND handle)
{
constexpr int MAX_CLASS_NAME = 256;
wchar_t className[MAX_CLASS_NAME];
// Get the class name associated with the handle
int result = GetClassName(handle, className, MAX_CLASS_NAME);
if (result != 0)
{
return std::wstring(className);
}
return L"";
}
In the above code, the GetClassName
function is called with the handle of the component as the first parameter. The second parameter is a buffer to receive the class name, and the third parameter specifies the maximum number of characters to retrieve.
The function returns the retrieved class name as a std::wstring
. If the GetClassName
function succeeds, the class name will be stored in the className
buffer and returned as a std::wstring
. If the function fails, an empty string will be returned.
You can then call this function by passing the handle of the component you want to retrieve the name from, like this:
cppHWND handle = // your handle value here
std::wstring componentName = GetComponentNameFromHandle(handle);
Make sure to include the necessary headers (Windows.h
) and handle any error conditions that may occur during the retrieval process.
