Thanks for your response.
the problem is getsockname() sometimes fails due the following microsoft issue:

I think you should use it because the site also talk about the resolution for the failure.

I want to avoid the complexity associated with WSADuplicateSocket. I just want to pass the port number across processes, thats my only requirement. I need some mechanism through which i can get socket number in parent process and pass it to the child process as an argument. By parent process i mean process that invokes the second process, which i call the child process.

Don't duplicate the socket at all.
Get the port number using the socket descriptor.
And pass this port number to the child process as a command line argument.

Delete all items of a CListBox

I am trying to delete all items of a CListBox

However, only the top item is removed once calling this routine, How do I delete everything ?

Thanks

<br />
numOfItems= listBox.GetCount();<br />
<br />
for (int i =0; i<=numOfItems; i++){<br />
lisBox.DeleteString(i);<br />
}<br />

CListBox::ResetContent[^].
Btw there's also a fundamantal flaw in your method. Consider what your loop does:
1. i becomes 0, the very first ("zeroth") item is deleted from your list, this will raise all other items 1 place, so 0 goes away, 1st becomes the 0th, 2nd becomes 1st, 3rd becomes 2nd and so on...
2. i now becomes 1, the 1st item in your list is deleted, and the ones under it jump up one place, so the 0th item is untouched, the 1st is deleted, 2nd becomes 1st, 3->2, 4->3 ...
3. i now becomes 2, 2nd item is deleted, so 0th is untouched, 1st is untouched, 2nd is deleted, 3rd becomes 2bd, 4->3 and so on...

Yourwelcome. Smile | :)

If you want to stick to the for loop, try movings in reverse, so something like:

for (int I = Count - 1; I >= 0; I--)
  listbox.DeleteString(I);

or simply do this:

for (int I = 0; I < Count; I++)
  listbox.DeleteString(0);

You probably don't have the platform SDK installed on one of the machine. I don't know if it still the case for VC2008, but for VC2005, if you downloaded the free version, you had to download yourself the platform SDK (the platform SDK contains all win32 core functionalities).

In that case, have a look at the C++ project directories (Tools->Options->Projects and Solutions->VC++ Directories) and check that the Windows SDK include directory is in your include path.

these 4 directories are present over there

$(VCInstallDir)atlmfc\include
$(WindowsSdkDir)\include
$(FrameworkSDKDir)include

Mmmmm - $(WindowsSdkDir)\include is the one that contains WinUser.h, which contains SetDlgItemText (well, actually SetDlgItemTextA and SetDlgItemTextW).

Soooo - guess the first thing you could try is cleaning your build and rebuilding it (maybe the pre-compiled header's got itself confused?), then the next thing you could try is running your .cpp file that doesn't compile through the C pre-processor (use cl -P or set the relevant options in your project settings) on your machine and also a machine where it does build and check for differences between the pre-processor output - the definition of SetDlgItemText obviously isn't getting through the pre-processor to the compiler.

I seem to remember running into this a few years ago, but I don't remember the specifics.

Have you googled it? My guess is that you haven't.

EDIT - It may have had something to do with the CFormView...

Getting child windows handle

Hi There.

I have a Dialog based Application: Title "ABC Application"

I want to launch this appiication and then want to set an edit box available on this window with some text.
This is what I am doing right now.

ShellExecute(NULL, L"open", L"C:\\Program Files\\ABC.exe", NULL, NULL, SW_SHOWNORMAL);


HWND WndOST2PST = NULL;
WndOST2PST = ::FindWindow(NULL,L"ABC Application");


if(WndOST2PST == NULL)
      return false;


//Need to get handle for child windows



//SetWindowText(WndOST2PST, L"Pankaj");

SendMessage(WndOST2PST, WM_DESTROY, 0, 0);

I am not able to get handle of that specific edit control. Please provide some pointers for the same.

Thanks
PanB

hi,you'd better get the window handle from one variable.
the dialog title may be not right in this course.

Try this

CString Text;
CWnd *pWnd = FindWindow(NULL, "Title");
CWnd *pChildWnd = pWnd->GetWindow(GW_CHILD);
while(pChildWnd) 
	{
	   UINT uiID = pChildWnd->GetDlgCtrlID();
	   pChildWnd->GetDlgItemText(uiID, Text);// To get caption
	   pChildWnd->SetDlgItemText(uiID, "Test");  //To set value into edit box
	
	   pWnd->SendMessage(WM_COMMAND, MAKEWPARAM(uiID, BN_CLICKED), (LPARAM)pChildWnd->m_hWnd);// To click on the control
	   pChildWnd = pChildWnd->GetWindow(GW_HWNDNEXT);
	}
