You can get your 'unmangled' names declared this way:

<br />
extern "C" {<br />
#include "gr_node_bin.h"<br />
}<br />

In other words, when you include header in CPP file for that of library written in C, you need to let compiler know now to make your OBJ look for UN-mangled names, since they will be UN-mangled in the other C-style library.

Ask for help: how can I re-appear such appearance?

21-Dec-05 22:24

If you have MSDN installed there is a sample project called ctrltest.

Try to search for it in the CD or hard disk (if you have it on disk).

It is a good example for "OwnerDrawn" (not me;P) menus for starters.

Hope this will help.

Happy christmas friends. May the Love of My Lord and Saviour Jesus bring forth Joy and Happiness into your life too.

Give the customer release DLLs or EXEs (whatever they are) with Debug Strings at the places where you might think crash has happened and then check the outputs.

Hello.

Read this[^]
article.
It has saved me more than once. If you do as the article says, you can pinpoint the exact code line in the source-code, where the error occurred! (In a release build).

I hope this question makes sense...

If I have a number of controls in a CView derived class, how can I get that view to pass on any messages from the controls to the view's parent window?

OpenEx function problem

Hi,
I have this code for connecting to SQL Server:
CString sql;
CDatabase m_database ;
sql.Format("DRIVER=SQL Server;SERVER=myserver;DATABASE=test;UID=administrator; PWD=admin;Trusted_Connection=No");
m_database.SetLoginTimeout(10);
m_database.SetQueryTimeout(10);
TRY{
m_database.OpenEx (sql,CDatabase::noOdbcDialog );
}
CATCH(CDBException, e){
m_database.Close();
MessageBox("Connection failed");
}
END_CATCH

I am connecting to a remote sql server. This code works fine if I'm connected in the network and i was able to catch the Exception, however, when I disconnect the host pc from network, an unknown exception was thrown. "Unknown software exception (0x0000409)..." . Is there any way to catch this exception ? It also happen when I mispelled the server name.

I have an CSpinButtonCtrl autobuddied with an EditBox. How can I get the CSpinButtonCtrl to inc/dec in 2's as I only want even numbers to appear in the EditBox and by default the CSpinButtonCtrl inc/decs in 1's.
Follows is a stripped down version of my implementation
In the .h file I declare

class C_VIEW : public CDialog<br />
{<br />
// Construction<br />
public:<br />
C_VIEW(CWnd* pParent = NULL);   // standard constructor<br />
// Dialog Data<br />
//{{AFX_DATA(C_VIEW)<br />
CSpinButtonCtrl	m_spinner;<br />
//}}AFX_DATA<br />
};

In the .cpp file I implement

void C_VIEW::DoDataExchange(CDataExchange* pDX)<br />
{<br />
  CDialog::DoDataExchange(pDX);<br />
  //{{AFX_DATA_MAP(C_VIEW)<br />
  DDX_Control(pDX, IDC_SPINNER, m_spinner);<br />
  //}}AFX_DATA_MAP<br />
}

In the initialisation routine I set the min/max range

BOOL C_VIEW::OnInitDialog() <br />
{<br />
  CDialog::OnInitDialog();<br />
  m_spinner.SetRange(0, 100);<br />
}

the value is saved when the dialog box is closed.

void C_VIEW::OnOK() //called when OK button is pressed in dialog box<br />
{<br />
  save_all_values();<br />
  CDialog::OnOK();<br />
}

I thought of rounding the value as it is saved, but that is not elegant and would misguide a user who had selected an odd value.

Do not use the UDS_SETBUDDYINT style, and instead handle the WM_VSCROLL message that the spin control sends to it's parent window. Get the position of the spin control, double it, and set the edit control's text accordingly. You also have to remember to set the spin controls position when the text in the edit control is changed to make sure the edit control and spin control stay in synch.

He only wanted EVEN numbers.

I would get value, see if it is odd, and add one.

if( X & 1 ) x++;

Use SetAccel()

UDACCEL accel;
accel.nSec=0;
accel.nInc=2; //take note, this is the one that does the trick.

SetAccel(1, &accel);

Totally cool!

I had only ever used accelerators to 'speed up' lengthy spins. Never occured to me to use one to force even numbers.

Of course, if an odd one ever gets int here (like they enter number directly in an edit field) ... Hmmmmmmm D'Oh! | :doh:

No it really works.
I tried starting with a 1 and it steps to 2,4,6 etc (or 0) automatically.
