IShellWindows::FindWindowSW returning S_FALSE
In the Windows API, IShellWindows::FindWindowSW
is a method used to find a specific window among the Shell windows. It is part of the ShellWindows interface, which allows you to enumerate and manipulate the collection of Shell windows (Windows Explorer windows, Internet Explorer windows, etc.) on the desktop.
The return value of S_FALSE
(0x0001) from IShellWindows::FindWindowSW
indicates that the method call was successful, but it did not find the specified window. The return value S_FALSE
is used as a success status code when a function successfully executes but does not return any specific result or data.
Here's how you can handle the return value of IShellWindows::FindWindowSW
in C++:
cpp#include <windows.h>
#include <exdisp.h> // Include the header for IShellWindows
int main() {
CoInitialize(NULL); // Initialize COM if you haven't already
IShellWindows* pShellWindows;
if (SUCCEEDED(CoCreateInstance(CLSID_ShellWindows, NULL, CLSCTX_ALL, IID_IShellWindows, (void**)&pShellWindows))) {
HWND hWnd;
VARIANT vEmpty;
VariantInit(&vEmpty);
// Find the window by the process ID or the window title, depending on your requirements
if (SUCCEEDED(pShellWindows->FindWindowSW(&vEmpty, &vEmpty, SWC_DESKTOP, (long*)&hWnd, SWFO_NEEDDISPATCH, NULL))) {
// Window found, do something with hWnd
} else {
// Window not found, handle accordingly
}
pShellWindows->Release();
}
CoUninitialize(); // Uninitialize COM
return 0;
}
In the example above, we attempt to find a Shell window using IShellWindows::FindWindowSW
. If the function returns S_FALSE
, it means that the specified window was not found. You can handle this case based on your application's requirements.
It's worth noting that the IShellWindows
interface provides various methods for working with Shell windows, and FindWindowSW
is just one of them. Make sure to review the documentation for the ShellWindows interface to understand all the available methods and their usage. Additionally, proper error handling and resource cleanup should be implemented in a real-world application.
