The solution you suggest is the solution I have tried, it is from CodeGuru

I've been trying for a while to locate the comment to the article at codeguru that had this idea but have been unable to locate it. You don't happen to have the article title by any chance.

The technique works so well and many ask for ways to detect an ISP/network connection so I thought I'd post it in an article for the benefit of all but I wanted to make sure to credit the person who passed the idea on. If I remember correctly, he also referred to someone else in a give credit where credit is do kinda way.

Its a shame the technique didn't make it into the codeguru "...Goodies..." book. They instead included one of the other half baked schemes that don't work well as a frontline detection technique. Some additional detection schemes would provide additional connectivity info after this initial check but only those techniques have made it into easy to find articles.

If you know the name of person to give credit to, that would also help.

Anyway, thanks in advance

Thanks Bob for tou patience in answering Laugh | :laugh:

. But still i think you are not clear with my requirement.

I have an internet connection and i am able to determine the connection too. My question is: "Is there a way to know whether the existing internet connection is through a dial-up connection or Wifi-connection or an Ethernet connection?"

If i get this it will be a breakthrough in my project. Sniff | :^)

Add .lib library to Visual C++ project?

Hello everyone,

I think I am getting kinda slow but I can't figure out how to add my own *.lib library to the project in Visual C++. I have looked through all linker settings and can't find the one where I can specify which library to use. I don't want to compile and link with a makefile because I have already set up all my files in the project. Would be nice if you could help me.

Thanks!

In MSVC6 you do the followingL
1. Select "Project->Settings" from the main menu.
2. Make sure the project (parent node) is selected in the tree and not one of the files.
3. Select the "Link" tab.
4. In the "Category" combo select "Input".
5. In the "Additional library path:" edit control add the directory where the library can be found (just the directory, not including the actual library name) if not already present.
6. In the "Object/library modules:" edit add the library to the end of the list.

Hi Steve,

In Visual Studio 2005 it is a bit different, but close enough to your description so I have found it. Definitely, struggling with VC++ at 5:00am was not very productive work. Smile | :)

Thanks much, man!

Hello all,

Currently, we are planning to do a project on WLAN Monitoring System in VC++.NET. We tried WRAPI. It is not showing any compilation error. But, finally, when it starts execution, it shows ntdll.dll initialization error. Why is it showing error? Also, immediately it is showing a Access Violation Error in user32.dll.

Please guide me. Frown | :(

Handle to a MFC dialog box window?

jc0dex10-Feb-06 19:26

Hello!

I'm working with an MFC dialog based app and am using:

SendMessage(GetDlgItem(hDlg, IDC_EDIT_CHATLOG),
EM_EXSETSEL, 0, (LPARAM)&ch);

But I don't have a way to get the hDlg parameter which is the handle to the window.

Anyone know how to get the handle to an mfc dialog box win?

thanks in advance,

jay

That depends on where that code is. Is it in a member function of the dialog? If so, just use the CWnd wrapper:

SendDlgItemMessage(IDC_EDIT_CHATLOG, EM_EXSETSEL, 0, (LPARAM)&ch);

Otherwise, use AfxGetMainWnd() to get a pointer to the main window:

AfxGetMainWnd()->SendDlgItemMessage(...);

Hi,

you can use one of the following 3 methods to retreive the handle of a control

1. insinde the dialog you can get a window object of the control:

CWnd* pWnd = GetDlgItem(IDC_EDIT1);
HWND hWnd = pWnd->GetSafeHwnd();

2. insinde the dialog you can get the handle of the control:

HWND hWnd2 = NULL;
GetDlgItem(IDC_EDIT1, &hWnd2);

3. from anywhere you can get a handle of a control by using:

HWND hWnd3 = ::GetDlgItem(pDlg->GetSafeHwnd(), IDC_EDIT1);

if you need to get a unknown window you'v got to find it using the following code:

HWND hwndThis = ::FindWindow(NULL, _T("DlgTest"));

where _T("DlgTest") is the caption of the window you are looking for

The HWND handle to the MFC dialog box, I think AfxGetMainWnd() will work but for some reason I've been having a bit of trouble trying to implement it in a small UDP voice chat server app.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
