I'm using an Access 97 database and I want to change this value programmatically (updating users databases).
I can read it by calling GetFieldInfo() using AFX_DAO_ALL_INFO, but there is no SetFieldInfo() function.
Any suggestions?

Look at DAOTABLE sample in VC++ help.
It shows how to create tables, fields,and indexes...

Hi!
In my MDI app, i want to add a "Print" button at each dialog box to allow to the user to print it.
Is it possible to print a dialog box?
I try to use the CWnd::Print() function. The help says "Call this member function to draw the current window in the specified device
context, which is most commonly in a printer device context."
But it doesn't work!
This is my code...
void CSACellDefDlg::OnPrint()
{
CDC dc;
CPrintDialog printDlg(FALSE);
// Get printer settings from user
if (printDlg.DoModal() == IDCANCEL)
return;
// Attach a printer DC
dc.Attach(printDlg.GetPrinterDC());
dc.m_bPrinting = TRUE;
// Get the application title and initialise print document details
DOCINFO di;
::ZeroMemory (&di, sizeof (DOCINFO));
di.cbSize = sizeof (DOCINFO);
di.lpszDocName = "";
// Begin a new print job
BOOL bPrintingOK = dc.StartDoc(&di);
// Get the printing extents and store in the m_rectDraw field of a
// CPrintInfo object
CPrintInfo Info;
Info.m_rectDraw.SetRect(0,0,dc.GetDeviceCaps(HORZRES),dc.GetDeviceCaps(VERTRES));
// begin new page
dc.StartPage();
this->Print(&dc,PRF_ERASEBKGND);
// end page
bPrintingOK = (dc.EndPage() > 0);
if (bPrintingOK)
// end a print job
dc.EndDoc();
else
// abort job.
dc.AbortDoc();
// detach the printer DC
dc.Detach();
}
Thanks for your help

Did you try giving your dialogs a WM_PRINTCLIENT message handler? And shouldn't you add the flag PRF_PRINTCLIENT?

Check out the printing section of this site - there are a couple of articles up now that should get you going in the right direction.

Hi,
I want to be able to print and do another things while I'm doing this ( my printing proccess is very slow), so I have made a thread that inherits from CWinThread, there I pass the handle of the printer Dc, then I convert it to a CDC and I begin to print, ... and then the program print and crashes...

Hi,
If you want to do this programatically.
Then use NetConnectionEnum()
"The NetConnectionEnum function lists all connections made to a shared resource on the server or all connections established from a particular computer. If there is more than one user using this connection, then it is possible to get more than one structure for the same connection, but with a different user name."
Make sure you link to netapi32.lib

If you can be patient for some days, the next release of WindowsNT System Manager will contain also the sharing management. Because I cannot send you an executable without your permission, I'm attaching only an image to show what it is now - it will be helpful if you can reply (here, or better, on my e-mail address) to tell me if this is what you're asking for...

Hi all,
I am writing a MDI application, which views are derivated
by CRichEditView. In the status bar, I want to display the
current position of the caret. The line number is easy to get,
just call GetRichEditCtrl().LineFromChar(-1), but how to determine the column?
Thanks in advance,
Thömmi

Thömmi,
You are actualy very close to the solution to this problem.
To get the caret position within current line you will have to look at two CRichEditCtrl member functions.
GetSel - if you are not handling the 'EN_SELCHANGE' notification than use this function to get current position of the caret. Vales returned contain character position from the beginning of the rich edit string.
Use the LineIndex function to get total number of characters before current line.
By subtracting chars before line from the caret position you will get column index in current line.
void CRichEditTestDlg::OnSelchangeRichedit(NMHDR* pNMHDR, LRESULT* pResult)
{
SELCHANGE *pSelChange = reinterpret_cast<selchange *="">(pNMHDR);
CString tempStr;
tempStr.Format( "ln: %d, col: %d",
m_richEdit.LineFromChar( -1 ),
pSelChange->chrg.cpMin - m_richEdit.LineIndex( -1 ));
SetDlgItemText( IDC_POS, tempStr );
*pResult = 0;
}

long startChar, endChar;
GetRichEditCtrl().GetSel(startChar, endChar);
startChar marks the start of the selection and endChar the end. If there is no current selection then the two values will be the same and will indicate the position of the caret.

Hi,
Does anyone know how to redirect cerr to a string stream?
Thank you
Hung

Hi Hung!
You can use the assignment operator of the cere.
Here is the small example which can help you:
#include "stdafx.h"
#include <iostream.h>
#include <strstrea.h>
char szBuffer[1024];
ostrstream cstr(szBuffer, sizeof(szBuffer)-1);
int main(int argc, char* argv[])
{
// put something in the output streams
cout << "Standart Output\n";
cerr << "Standart Error\n";
cstr << "***Our String**\n";
// use the assignment operator to change the cerr
cerr = cstr;
cout << "Standart Output\n";
cerr << "Standart Error After Assigment\n";
// show the content of our cstr
//cout << cstr.str();
cout << endl << "Preess ENTER to exit" << endl;
getchar();
return 0;
}

The autosize functions need some tweaking which I will do in the next release. This should solve the problem.

Hi!
We have a multi-threaded application, and want to use HTML Help, so we link with htmlhelp.lib. And run in the error with the LIBCMT lib. I changed the project settings to ignore it. But doesn't this affect the multi-threading of the app?
One solution mentioned in the MSKB is to link with hhctrl.lib. Okay, but where can I find it?

I'm not sure if this will help, but we are using Html Help that calls up a .chm file and I just do a ShellExecute on hh.exe and pass it the appropriate page that is supposed to go to. I do this in the OnHelpInfo function for every dialog. If you need more information let me know.

Hi Carole,
thanks for your reply, but calling HtmlHelp via ShellExecute was not an option, because I want to handle it in one place, in CWinApp::WinHelp. But the problem is solved now. Downloading the newest version of the HTML Help Workshop from the microsoft site solved the problem.

I want to use MAPI32.DLL to send/receive email.
First, I'm success to send e-mail by MAPISendMail function. (refernced by CDocument::OnFileSendMail())
But I fail to received the mail. I guess the receiving flow below.
MAPILogon call(Session establish)->MAPIFindNext call(mail search)->MAPIReadMail(mail read)->MAPILogoff(session cut off)->MAPIFreeBuffer(message struct memory release)
Well, I don't know this flow is right.
Anyway, I'm success to call MAPILogon function. but second calling (MAPIFindNext) is failed (MAPI_E_FAILURE)
Help me!

VC6, MFC, Win95/98
I have a question that I can not seem to find an answer or sample code. I want the following behavior:
The first opened child windows, w1, fills the CMDIFrameWnd Client window from corner to corner. If the user opens a second window, w1 and w2 tile vertically. If a third child window is opens, w1 and w2 stay side by side at the top half and w3 tiles bellow w1 and w2 from far left to right. If a fourth window opens, child w3 moves over to the left 1/2 and child w4 takes it place bellow w2 and to the right of w3. The end result equals four child windows; w1 upper/left, w2 upper/right, w3 lower/left, w4 lower/right. As the end user closes the windows, I want to reverse the open process. What is the best way to achieve my goal? Is there any source code showing how to do this? All suggestion welcome and source greatly appreciated

1) Write a window class dervied from CWnd.
class MdiClient : public CWnd
{
DECLARE_DYNAMIC( MdiClient )
public:
// Construction/Destruction
MdiClient();
protected:
// ClassWizard generated message map functions
//{{AFX_MSG( MdiClient )
//}}AFX_MSG
afx_msg LRESULT OnMDICreate( WPARAM, LPARAM lParam );
afx_msg LRESULT OnMDIDestroy( WPARAM wParam, LPARAM );
DECLARE_MESSAGE_MAP()
int m_nMDICount;
};
IMPLEMENT_DYNAMIC( MdiClient, CWnd )
// Construction/Destruction
MdiClient::MdiClient()
: m_nMDICount( 0 )
{
}
// ClassWizard generated message map functions
BEGIN_MESSAGE_MAP( CLASS, BASE )
//{{AFX_MSG_MAP( MdiClient )
//}}AFX_MSG_MAP
ON_MESSAGE( WM_MDICREATE, OnMDICreate )
ON_MESSAGE( WM_MDIDESTROY, OnMDIDestroy )
END_MESSAGE_MAP()
LRESULT MdiClient::OnMDICreate( WPARAM, LPARAM lParam )
{
LPMDICREATESTRUCT lpmdic = (LPMDICREATESTRUCT)lParam;
HWND hwndMDIChild = (HWND)CWnd::DefWindowProc( WM_MDICREATE, 0L, (LRESULT)lpmdic );
if ( hwndMDIChild != NULL )
{
++m_nMDICount;
// Reposition the MDI childs like you want
}
return (LRESULT)hwndMDIChild;
}
LRESULT MdiClient::OnMDIDestroy( WPARAM wParam, LPARAM )
{
--m_nMDICount;
if ( m_nMDICount > 0 )
{
// Reposition the MDI childs like you want
}
return CWnd::DefWindowProc( WM_MDIDESTROY, wParam, 0L );
}
2) Derive a class from CMDIFrameWnd, and overwrite OnCreate.
int MdiFrameWnd::OnCreate( LPCREATESTRUCT lpCreateStruct )
{
if( CMDIFrameWnd::OnCreate( lpCreateStruct ) == -1 )
{
return -1;
}
m_pwndMdiClient = new MdiClient;
if( !m_pwndMdiClient->SubclassWindow( m_hWndMDIClient ) )
{
return -1;
}
return 0;
}
