获取桌面图标的名称

	//cout << n << endl;
	//cout <<

}

只能显示图标数量，不能显示名称

你这个“szText”只剩下了遍历的最后一个图标名，注意要累加出来

    hDeskTop = FindWindow(_T("progman"), NULL); 
    hDeskTop = FindWindowEx(hDeskTop, 0, _T("shelldll_defview"), NULL); 
    hDeskTop = FindWindowEx(hDeskTop, 0, _T("syslistview32"), NULL);

换成

	hDeskTop= ::GetTopWindow(::GetTopWindow(::FindWindow("ProgMan", NULL)));

试试看

下面是一个获取listview中item的名称的代码，楼主可以参考一下

bool getItemTextFromListBox(HWND hWndListView, int item, int subItem, TCHAR** ppwszText) 
{
	bool retcode=false;
	TCHAR szReadBuffer[1024];
	memset(szReadBuffer, 0, sizeof(szReadBuffer) );
	LV_ITEM* plvi=NULL;

	DWORD dwProcessId;
	GetWindowThreadProcessId(hWndListView, &dwProcessId);
	// Open a handle to the remote process's kernel object
	HANDLE hProcess = OpenProcess(
		PROCESS_VM_OPERATION | PROCESS_VM_READ | PROCESS_VM_WRITE, 
		FALSE, dwProcessId);
	
	if (hProcess == NULL) {
		//MessageBox(NULL, __TEXT("Could not communicate with process"), 
		//	"ERROR", MB_OK | MB_ICONWARNING);
		goto cleanup;
	}

	// Allocate memory in the remote process's address space
	plvi = (LV_ITEM*) VirtualAllocEx(hProcess, 
		NULL, 4096, MEM_RESERVE | MEM_COMMIT, PAGE_READWRITE);

	if(plvi==NULL) {
		goto cleanup;
	}

	// Get the ListView item's text data
	// Initialize a local LV_ITEM structure
	LV_ITEM lvi;
	memset(&lvi, 0, sizeof(LV_ITEM) );
	lvi.mask = LVIF_TEXT;
	lvi.iItem = item; 
	lvi.iSubItem = subItem; 
	// NOTE: The text data immediately follows the LV_ITEM structure
	// in the memory block allocated in the remote process.
	lvi.pszText = (LPTSTR) (plvi + 1); 
	lvi.cchTextMax = 100; 

	// Write the local LV_ITEM structure to the remote memory block
	if( !WriteProcessMemory(hProcess, plvi, &lvi, sizeof(lvi), NULL) ) {
		goto cleanup;
	}

	// Tell the ListView control to fill the remote LV_ITEM structure
	ListView_GetItem(hWndListView, plvi);

	
	// Read the remote text string into the end of our clipboard buffer
	if( !ReadProcessMemory(hProcess, plvi + 1, (LPVOID) &szReadBuffer, sizeof(szReadBuffer), NULL) ) {
		goto cleanup;
	}

	*ppwszText = (TCHAR*) malloc( _tcslen( szReadBuffer ) + sizeof(TCHAR) );	
	if(!*ppwszText) {
		goto cleanup;
	}

	retcode=true;
	_tcscpy(*ppwszText, szReadBuffer); 

	//	ListView_SetItemState(hWndListView, -1, 0, LVIS_SELECTED);

cleanup:
	// Free the memory in the remote process's address space
	if(hProcess) {
		VirtualFreeEx(hProcess, plvi, 0, MEM_RELEASE);
		// Cleanup and put our results on the clipboard
		CloseHandle(hProcess);
	}
	return retcode;
}
