Comment
1 / 1
Creating a Windows 10 C++ Network Explorer Plugins context menu handler involves implementing a shell extension that adds custom context menu options for network items in File Explorer. Here's a basic example to get you started:
Set up the project:
- Create a new C++ project in Visual Studio.
- Select the "Dynamic-Link Library (DLL)" project template.
Include necessary headers:
- Add the following includes to your source file:cpp
#include <windows.h>
#include <shobjidl.h>
- Add the following includes to your source file:
Implement the context menu handler:
- Define a class that implements the
IContextMenu
interface. This class will handle the context menu actions.cppclass NetworkContextMenu : public IContextMenu
{
public:
// Implement the required IUnknown methods
// Implement the IContextMenu methods
STDMETHODIMP QueryContextMenu(HMENU hMenu, UINT indexMenu, UINT idCmdFirst, UINT idCmdLast, UINT uFlags);
STDMETHODIMP InvokeCommand(LPCMINVOKECOMMANDINFO pici);
STDMETHODIMP GetCommandString(UINT_PTR idCmd, UINT uType, UINT* pReserved, LPSTR pszName, UINT cchMax);
};
- Define a class that implements the
Implement the
QueryContextMenu
method:- This method adds custom menu items to the context menu.cpp
STDMETHODIMP NetworkContextMenu::QueryContextMenu(HMENU hMenu, UINT indexMenu, UINT idCmdFirst, UINT idCmdLast, UINT uFlags)
{
// Add your custom menu items to the hMenu
InsertMenu(hMenu, indexMenu++, MF_STRING | MF_BYPOSITION, idCmdFirst, L"Custom Option");
// Return the number of added menu items
return MAKE_HRESULT(SEVERITY_SUCCESS, 0, indexMenu - 1);
}
- This method adds custom menu items to the context menu.
Implement the
InvokeCommand
method:- This method handles the action when the user selects a menu item.cpp
STDMETHODIMP NetworkContextMenu::InvokeCommand(LPCMINVOKECOMMANDINFO pici)
{
// Check if the action is triggered by a menu item
if (HIWORD(pici->lpVerb) == 0)
{
// Get the identifier of the menu item
UINT idCmd = LOWORD(pici->lpVerb);
// Handle the selected menu item
switch (idCmd)
{
case 0:
// Custom menu item action
MessageBox(NULL, L"Custom Option Selected", L"Context Menu", MB_OK | MB_ICONINFORMATION);
break;
// Add additional cases for other menu items
default:
return E_INVALIDARG;
}
}
return S_OK;
}
- This method handles the action when the user selects a menu item.
Implement the
GetCommandString
method:- This method retrieves the text for the menu item.cpp
STDMETHODIMP NetworkContextMenu::GetCommandString(UINT_PTR idCmd, UINT uType, UINT* pReserved, LPSTR pszName, UINT cchMax)
{
// Check the uType flag
if (uType & GCS_HELPTEXT)
{
// Set the help text for the menu item
StringCchCopyA(pszName, cchMax, "Custom Option Help Text");
return S_OK;
}
return E_INVALIDARG;
}
- This method retrieves the text for the menu item.
Implement the DllMain function:
- Add the DllMain function to initialize the context menu handler.cpp
BOOL APIENTRY DllMain(HMODULE hModule, DWORD ul_reason_for_call, LPVOID lpReserved)
{
switch (ul_reason
- Add the DllMain function to initialize the context menu handler.
