Get a list of devices (Microsoft Visual Studio 2010) with interface design

Similar to the last Fetch device list (Microsoft Visual Studio 2010), New Project->mfc...-> dialog-based completion Class View point open Item double click Caaadlg Click Caaadlg::oninitdial OG copies the last code to TODO and then configures the path like the last:

Make the following settings for the compiler:

Item-->** Properties (ALT+F7)
Configuration Properties-->c/c++--> General--Additional include directory--(the file path where the head file is located is added to the additional directory)

Item-->** Properties (ALT+F7)
Configure the properties-----------Add to the library directory (the directory where the Packet.lib;wpcap.lib is located)

Item-->** Properties (ALT+F7)
Configuration Properties--linker--Add dependency--add "; Packet.lib;wpcap.lib "

Item-->** Properties (ALT+F7)
Configuration Properties-->c/c++--> Preprocessor---preprocessor definition--add "; Have_remote "

The first step is to change the project-project Properties-Configuration Properties-connector-list file-embed list to "no". If it doesn't solve the problem, go to the second step.

Step Two: Check if the computer is a 64bit operating system, if so, continue with the following actions.

Find out if there are two cvtres.exe.

C:\Program Files (x86) \microsoft Visual Studio 10.0\vc\bin\cvtres.exe

C:\Windows\Microsoft.NET\Framework\v4.0.30319\cvtres.exe

Right-click Properties-Details, view both version numbers, delete/rename older versions, or reset the path variable.

The root of the solution is the second step, after removing the old version of Cvtres.exe, you do not need to set the configuration every time.

For example: Del C:\Program Files (x86) \microsoft Visual Studio 10.0\vc\bin\cvtres.exe

Modify the code as follows:

BbbDlg.cpp: Implementing Files

//

#include "stdafx.h"

#include "Bbb.h"

#include "BbbDlg.h"

#include "afxdialogex.h"

#include "Pcap.h"

Sets the icon for this dialog box. When the main application window is not a dialog box, the framework automatically

Perform this action

If you add a Minimize button to the dialog box, you need the following code

To draw the icon. For MFC applications that use the document/view model,

This will be done automatically by the framework.

void Cbbbdlg::onpaint ()

{

if (Isiconic ())

{

CPAINTDC DC (this); Device context for drawing

SendMessage (Wm_iconerasebkgnd, Reinterpret_cast<wparam> (DC). GETSAFEHDC ()), 0);

Center the icon in the workspace rectangle

int cxicon = GetSystemMetrics (Sm_cxicon);

int cyicon = GetSystemMetrics (Sm_cyicon);

CRect rect;

GetClientRect (&rect);

int x = (rect. Width ()-Cxicon + 1)/2;

int y = (rect. Height ()-Cyicon + 1)/2;

Draw icon

dc. DrawIcon (x, y, M_hicon);

}

Else

{

Cdialogex::onpaint ();

}

}

The system calls this function to get the cursor when the user drags the minimized window

Show.

Hcursor Cbbbdlg::onquerydragicon ()

{

Return static_cast

}

void Cbbbdlg::oncbnselchangecombo1 ()

{
