Rahul Vaishnav

Hi all, Please go through below function. Copy any file/folder & then use this function to past Shortcut It is crashing "InvokeCommand". Please help me.

{
CoInitialize(NULL);
IShellFolder* psf;
HWND hWnd = GetDesktopWindow();
HRESULT hr;
if (SUCCEEDED(SHGetDesktopFolder(&psf)))
{
IContextMenu* pcm;
if (SUCCEEDED(psf->CreateViewObject(hWnd,IID_IContextMenu,(void**)&pcm)))
{
HMENU hmenu = CreatePopupMenu();
if (hmenu != NULL) {
if (SUCCEEDED(pcm->QueryContextMenu(hmenu, 0,
0, 0xff, // since we're invoking by canonical name the menu ID range passed to QueryContextMenu can be arbitrary
CMF_NORMAL))) {
CMINVOKECOMMANDINFO cmi={0};
cmi.hwnd=hWnd;
cmi.cbSize=sizeof(cmi);
cmi.lpVerb= ".lnk";
hr= pcm->InvokeCommand(&cmi);
if (SUCCEEDED(hr)) {
MessageBox(hWnd, TEXT("Shortcut created"), TEXT("Message"), 0);
}
}
DestroyMenu(hmenu);
}
pcm->Release();
}
psf->Release();
}

It looks like the content of your CMINVOKECOMMANDINFO structure is not complete; take a look at the documentation[^] for further details.

It's time for a new signature.

Hi Richard, Thanks for reply... now I have tried below code... Below code is not showing crash as I have used "link" as lpVerb. as you said I have provided all Content of CMINVOKECOMMANDINFO structure. "InvokeCommand" is return S_OK But still Paste Shortcut is not happening on Desktop. :-(

void PasteShortcut()
{
try
{
CoInitialize(NULL);

	IShellFolder\* psf;
	HWND hWnd = GetDesktopWindow();
	HRESULT hr;
	if (SUCCEEDED(SHGetDesktopFolder(&psf)))
	{
		IContextMenu\* pcm;
		if (SUCCEEDED(psf->CreateViewObject(hWnd,IID\_IContextMenu,(void\*\*)&pcm)))
		{
			HMENU hmenu = CreatePopupMenu();
			if (hmenu != NULL) {
				if (SUCCEEDED(pcm->QueryContextMenu(hmenu, 0,
					0 , 0xff,	// since we're invoking by canonical name the menu ID range passed to QueryContextMenu can be arbitrary
					CMF\_NORMAL))) {
						CMINVOKECOMMANDINFO  cmi;
					cmi.cbSize = sizeof(CMINVOKECOMMANDINFO);
					cmi.fMask = 0;
					cmi.hwnd = hWnd;
					cmi.lpVerb ="link" ;//(LPCSTR)(INT\_PTR)(idCmd - 1);
					cmi.lpParameters = NULL;
					cmi.lpDirectory = NULL;
					cmi.nShow = SW\_NORMAL;
					cmi.dwHotKey = 0;
					cmi.hIcon = NULL;
					hr = pcm->InvokeCommand(&cmi);
						
						if (SUCCEEDED(hr)) {
							MessageBox(hWnd, TEXT("Shortcut created"), TEXT("Message"), 0);
						}
				}
				DestroyMenu(hmenu);
			}
			pcm->Release();
		}
		psf->Release();
	}
	CoUninitialize();

}
catch(...)
{
}

I don't see anything in the above that looks like a source file or a destination shortcut.
