Visual C++ :: How To List Programmable Wake Devices
Dec 4, 2013
I'm trying to achieve the results of the following command that lists all programmable wake devices, or those that can be set/reset to wake the system:
Code: powercfg -devicequery wake_programmable
I need to do the same from a C++ service. I'm using the code similar to this, but it gives me a smaller list. Here's how I call DevicePowerEnumDevices:
Code:
if(DevicePowerEnumDevices(index,
DEVICEPOWER_FILTER_DEVICES_PRESENT,
PDCAP_WAKE_FROM_D0_SUPPORTED |
PDCAP_WAKE_FROM_D1_SUPPORTED |
[Code] ......
What flags am I missing for wake_programmable?

Is it possible to see what usb devices are connected to a hub?
An example would be:
Onboard usb hub:
usb mass storage device
webcam imaging device
superspeed hub:
Mass storage device
Printer
MTD device
I am currently able to get a list of all connected devices with ManagementobjectCollection in C# but that doesn't give me any hierarchy (as far as I am aware).
I am not dead set on C#, I assumed that would be fastest way to get this up and running.

I want to connect to other computers remotely and for example grabbing some data from them. Do we have any c++ library for this purpose? And if yes, any good documentation about it.

I have a device that have some communication protocols and it will respond and send some specific data when somebody communicates with the device. I tried to build a C code that will send those protocols to the device and then store those sending data. Now I don't understand that how to send those commands. Other things than that I can manage with the file handling programming.Is there any predefined function using which it will send some specific data or something like that??

I know I can use ping internally to test a device's connectivity. What can I use to test devices on another network (assuming ports are forwarded, and their IP addresses are at my disposal)? I was looking into the TCP Client class.. would that also work with devices using DynDNS?

There is a list control in Windows.
When I create a list control I can assign an image list to it with the ListView_SetImageList().
By default, when just created there is no image list assigned as can be checked with ListView_GetImageList().
Now, what should happen when I do following call:
Create list control.
Create an image list
Get the current image list
Assign an image list to list control
Display some items
Assign an old image list to list control.
Does strings on the list control should be indented?

The documentation states that "An image list is a collection of same-sized images" [URL].....
But how do I retrieve that size? I have a pointer to an empty image list. The size was set during creation, but that's out of my control.

The program I have below. If you copy and paste it it should work. However, When I uncomment my search function I get lots of errors and I think it has to do with incorrect syntax of it being a template. Need to do this search function:
Linked.h header file
Code:
#ifndef LINKED_H
#define LINKED_H
#include<iostream>
template <class T>
class Linked {
private:
// Declare a structure for the list

How would I go about selecting a subitem in a listview control with just pure Win32 API? I know it's possible with MFC... but I can't use MFC for this project. Right now, when you click on a subitem , it selects only the first column of the row . I used the following by referring internet. But its not working.
HTML Code:
iSlected=SendMessage(hList,LVM_GETNEXTITEM,-1,LVNI_FOCUSED|LVNI_SELECTED);
ListView_SetItemState(hList,iSlected,LVIS_FOCUSED|LVIS_SELECTED,0x000F);

I want to know how to list the all the symbols in the shared library(dll or .so file). I dont want commands like nm or objdump or depends.exe . I want to get the list of functions available in shared library programmatically at runtime (after calling loadlibrary/dlopen and GetProcAddress/dlsym). Is there a way to get the complete signature of functions in a shared library?

I dynamically allocate a new list in the recMergeSort function which should run a constructor but when it get to the functions that use it, I get error C2065: 'otherHead' : undeclared identifier. I have tried setting it to NULL and it didn't work. I even copied the default constructor to a set function and I still get the errors.
Code:
template<class Type>
void unorderedLinkedList<Type>::recMergeSort(nodeType<Type>* &head) {
otherHead = new nodeType<Type>;
if (head !=NULL)
if (head->link != NULL)
[Code] ....
wonder if I'm sending the correct data type. Here is the heading of the functions that I'm using from the book.
Code:
void unorderedLinkedList<Type>::divideList(nodeType<Type>* first1,
nodeType<Type>* first2)

I am trying to make a basic app that will loop through an unordered list with repeats and count how many times a specific item repeats. Example would be I select a state from the list box and it will tell me how many times it is listed.
This is the code I have up so far, trying to keep it basic. I am missing something, something related to the counter? I think I have some of the better half up but I am not sure...
Code:
Private Sub ListBox1_SelectedIndexChanged(sender As Object, e As EventArgs) Handles lstBox.SelectedIndexChanged
Dim wins As String = lstBox.SelectedIndex
Dim foundwins As Boolean = False
Dim i As Integer = -1
[Code] ....

- Remove a person's record by entering their name
-Return records for all people, sorted according to an information type other than age
-Enter a task which needs doing, a priority entered for its urgency
-View highest priority task on the list
-User should be able to remove highest priority item on the list
How to develop this application on a console command line interface style or any other style.

21.06 34.06 5.0
12.78 45.25 6.9
12.89 45.98 5.5

I'm supposed to make a basic text editor using a doubly linked list, I have pretty much written most of it but keep coming across several problems. In certain places,all marked in the code, I get the error "expected a declaration" ive looked online and nothing ive found works. And secondly I also get the error" declaration has no storage class or type specifier" but i havent been able to find anything that works either.
Code:
#include "stdafx.h"
#include <iostream>
#include <fstream>
#include <assert.h>
#include <string>

I'm trying to use the given Iterators to overload my = operator to print my list to screen. I keep getting Link2019 error though and have narrowed the problem down to my print operator. I'm wondering if it has anything to do with the fact that my operator is in private part of class? I'm new to this concept.
Code:
#include "List.h"
// methods for Node all
//ME
Node::Node( const string &s, Node * p, Node * z) : word( s ), next( p ), prev(z)//constructor {
word = s; // init. word data with a copy of s
next = p; // next pointer points to p

You need to write a permute class that will take first and second strings to rearrange letters in first, followed by second. For example, if the first is “CAT” string and second is “MAN” string, then the program would print the strings TACMAN, ATCMAN, CTAMAN, TCAMAN, ACTMAN, and CATMAN. The first and second strings can be any length of string or a null.
The permute class uses a Note class as link list note to link all letters arrangement. The permute class has Note pointers, firstNote and lastNote, to point to the beginning and ending Notes of the link list as private data members. There are three other private data members (total, firstString and secondString) to store the total possible number of arrangements and strings pass into the class.
Write a driver to test the permute class to pass in any two strings of any sizes.
Other than mention in the following, you can add more classes, functions, and private data members to this program.
Note class:The Note class needs to have two private data members and a constructor. The two private data members are data and p pointer. The data’s data type is string and p pointer is Note. The Note class constructor has two parameters, one is string and the other is Note pointer.
Permute class:The Permute class has five private data members (*firstNote, *lastNote, total, firstString and secondString). The firstNote and lastNote pointers are point to Note. The total has integer data type. The firstString and secondString have string data type.
There should have at least three public member functions, Permute, permutation and print. The Permute function is the constructor which takes strings to initialize the private data members. The permutation function does the recursive call to arrange the strings and setup the link list. The print function will print out the private data member information.
Driver file:The driver file should declare a Permute eight elements pointer array. Instantiate eight Permute object with the following eight set of data and assign the object to the pointer array. Use a repetition to call the object’s print function to print out the private data member information. If the total of the permute private data member is less than 100 then print out the permutated letters four in a row, otherwise print out 9 in a row.
first = "", second="",
first = "", second ="CATMAN",
first = "C", second ="ATMAN",
first = "CA", second ="TMAN",
first = "CAT", second ="MAN",
first = "CATM", second ="AN",
first = "CATMA", second ="N",
first 1 = "CATMAN", second ="";
