what's your question exactly ? you want to rewrite thos function ?
what for ?

moreover, if you work with C++ strings, you'd better forget those old char*. they are a legacy from the C language, kept for compatibility.
however, you should use the std::string class instead; which class proposes all the functionnality you want to redevelop here (if i get you well)

You shouldn't be using these low level and old fashioned string manipulations routines without a compelling reason to do so. Instead use a string class such as the standard library's std::string or MFC's CString.

You need to track where data is lost. I would start with setting up a break point where I start reading date from the database.

start by adding a name to your codeproject account. i like to know who i speak to.

then look in the properties dialog over your propertySheet in the resource editor, and spot the minimize/maximize options...

22-Mar-07 21:57

I cant get the damn list box to change the ownerdraw property when i subclass it.
Part of the code :

    CWnd * wnd = NULL;
    while (wnd = FindWindowEx(this->m_hWnd,(wnd == NULL ? NULL : wnd->m_hWnd),"ListBox",NULL))
    {
        MyListBox * temp = new MyListBox();
        temp->SubclassWindow(wnd->m_hWnd);
        temp->ModifyStyle(0,LBS_OWNERDRAWFIXED);
        TempControlAdd((CWnd*)temp); //for cleanup later
        temp = NULL;
    }

Thanks for the Help.

Hi there,

I think the LBS_OWNERDRAW* styles can be set only upon creation of the listbox control.
