If by "regular dll" you mean a non-MFC DLL, this is rather contradictory, don't you think?

I would guess that it's too early to be calling such functions. The DLL is not fully initialized at this point, and something within CDialog requires the DLL to be up and ready to go.

One would assume you are connected with this business. You should say so or not, and don't post anonymously.

There is only one C++ product on the site, so I can't see it being very usefull to folks here at CP. The site also seems difficult to use to me at least. Confused | :confused:

How to get WHOIS information in my app?

Hi,
I want to implement a function to lookup internet IP address to get its coresponding netblock information in my developing internet app.
Perhaps,my question is how to get WHOIS information in my program. Should my app connect to WHOIS server, such as APNIC WHOIS server?

For example,
if I lookup 202.84.144.73, I want to get its information
inetnum: 202.84.128.0 - 202.84.191.255
netname: HKT,HK
... and so on.

Any ideas? Thanks in advance.

You could follow this rfc and then parse the output from the server:

If you're using MFC, use CenterWindow(CWnd::GetDesktopWindow()) in your OnInitDialog() handler.

If you're not using MFC, you'll have to do a MoveWindow() and calculate the position where it should be. Look at the source code for CWnd::CenterWindow() to get an idea on how to do this.

Dear ALL,

I am developing an application for Windows NT/2000/XP. I need to know the path of root directory in my application.

Is there any API to know the root directory path (ie. c:\winnt or c:\windows)

Thanks in advance.

Hi world,

I want a simple dialog box (like CFileDialog) who let the user choose only a directory (not a file)...
Can somebody give me a simple example which does that?

Thanks in advance...

  caPathName[0] = 0;<br />
<br />
  GetDlgItemText(IDC_MYCTRL_TO_BACKFILL,caPathName,MAX_PATH);<br />

  BROWSEINFO sBI;<br />
  memset(&sBI,0,sizeof(BROWSEINFO));<br />
<br />
  sBI.hwndOwner = m_hWnd;<br />
  sBI.pidlRoot = NULL;<br />

How to insert a row in FlexGrid?

Radha Nair24-Jun-03 22:57

24-Jun-03 22:57

My application uses a Flexgrid. Iam using the first row as the header. I need to insert new rows (data rows) after the first row (as the second row). Every new row inserted must become the second row and the remaining rows should get pushed down. Resetting the number of rows works but it appends a row at the end of the grid. Is there any way to achieve this? Where can I get the complete documentation on Flexgrid?

thanks.

void CMSHFlexGrid::AddItem(LPCTSTR Item, const VARIANT& Index) adds a new row. If you want to add a new row after the header then just call:
AddItem( Item, _variant_t((long)1) );
If you want the documentation for FlexGrid, go to Project->Add to project->Components and controls and then find the flexgrid control. Select it and then click More Info.

stl set bug ?

Brian van der Beek24-Jun-03 21:35

I have a stl set with pointers to objects. When I insert() a reference to one of these objects in the empty set I get an access violation in the while loop of the following code:

<br />
void _Dec()<br />
                        {if (_Color(_Ptr) == _Red<br />
                                && _Parent(_Parent(_Ptr)) == _Ptr)<br />
                                _Ptr = _Right(_Ptr);<br />
                        else if (_Left(_Ptr) != _Nil)<br />
                                _Ptr = _Max(_Left(_Ptr));<br />
                        else<br />
                                {_Nodeptr _P;<br />
                                while (_Ptr == _Left(_P = _Parent(_Ptr)))<br />
                                        _Ptr = _P;<br />
                                _Ptr = _P; }}<br />

When I change the set to a list an push_back() the same object I works fine. Is this an stl bug, or must I be doing something wrong?
