  - MFC >> Bitmap Not DisplayedA bitmap that appears in the MFC dialog editor does not display when the
    application runs. The property settings and ID are the same in the VS 2003
    version and the VS 6 version. The VS 6 version works fine.
    
    It appears the update from VC++ 6 to VC++ 2003 has changed the mapping to
    the runtime bitmap file, but why does the bitmap picture appear (as it
    should) in the dialog editor, but not in the running version? The bitmap is
    labeled as a "system" bitmap, but this is a custom developed bitmap (lots of
    colors).
    
    Any clues to why the bitmap will not display and how to fix it?
    
    Thanks!

    Does the compiled code really run faster (at runtime) when having

  - MFC >> Setting font for StaticText ControlHello,
    
    I'd like to set the size, fontname and color for one of my StaticText
    controls on my dialog on a Visual Studio 2005 C++ MFC native project.
    I've found out this control has a SetFont method(), which I presume enable
    to set the styles as I've mentioned above, but I've got a little confused
    about the parameters.
    
    Is the SetFont() method the right/best way for setting the font for the
    StaticText control?
    If so, how I could set this font from my dialog class?
    Do I have to set a member variable for the class for this purpose?
    Where is the best place to set the font? The MyDlg::OnInitDialog() ?

  - Visual Basic [VB] >> How to handle nulls in a construcorHi, Im real new at this so be gentle. I want to create a customer
    object based on the results of an sql query to the customers table, ie
    one object per row, and then add each of these objects to an arraylist
    and then on to some datbinding in a listbox. Therefore, for each row
    sent back by the datareader, I try to create the new customer object
    and pass all the data in the row as part of the constructor. But, I
    declared the data fields in the customer class to be the same data type
    as those in the database but null causes a problem. To get round the
    problem, I just made addtional New constuctors for each column which
    may have nulls and then set the datfields to empty strings inside the
    constructor and thus not pass the null data at all from the datreader
    row. But that is a lot of kludge to test for null before the call to
    the constructor so that i call the right constructor. i tried to have
    constructors which accepts nulls as arguments and then set the private
    data fields to empty strings from there but ran in to cast problems
    *(esp with strict ON) in the call to the constructor.
    What is the right way to create objects whose private data fields are
    of one data type , but whose arguments might be null when they are
    instantiated and how should null arguments be specified.

  - Mcse >> The Practice Test Package Development: A New Service on the Certification Market01/19/2005 - Visual CertExam Software has launched the practice test
    package development service to making it easier and less expensive for
    companies to create practice tests.
    
    The practice test package development service will provide you with a
    universal solution for easy development and distribution of your own
    practice exams.
    
    The practice test package is a standalone setup program (setup.exe)
    that contains a question bank and the application for taking tests.
    These packages are very similar to Transcender and Self Test Software
    practice tests.
    
    Using this service sets you free from having to develop your own
    software and thus makes the process of development your own practice
    exams simpler and less expensive.
    
    A practice test package includes the following features:
    
    - The question bank and the application for taking test are
    distributed as a single setup.exe file. This means that your users
    don't need to buy and install any additional software in order to take
    your tests.
    - If you are a small company and have no an opportunity to develop
    your own test engine, you can obtain the professional solution for
    practice test delivery for a low cost.
    - You can freely update a question bank in order to keep your test
    actual.
    - Each practice test package has a build-in activation mechanism.

  - Visual Basic [VB] >> MarshalingGuys, please help. I am trying to make this work from at least 4 months.
    I am new to programming and some things are difficult to me, but I really
    need to make my project work.
    I can't find anything helpfull in internet for 4 months ;-( .
    Please someone who is more expirenced help me.
    
    I am trying to use the Terminal Server APIs
    There is as an API function WTSEnumerateSessions, which returns a
    WTS_SESSION_INFO custom structure n times.
    Actually it returns pointer to it.
    I just can't get it working in VB .NET
    While searching through MSDN I've found something, but I need an opinion
    from someone more experienced.
    
    The text is:
    ======
    Formatted Non-Blittable Classes
    Formatted non-blittable classes have fixed layout (formatted) but the data
    representation is different in managed and unmanaged memory. The data can
    require transformation under the following conditions:
    
    If a non-blittable class is marshaled by value, the callee receives a
    pointer to a copy of the data structure.
    If a non-blittable class is marshaled by reference, the callee receives
    a pointer to a pointer to a copy of the data structure.
    If the InAttribute attribute is set, this copy is always initialized
    with the instance's state, marshaling as necessary.
    If the OutAttribute attribute is set, the state is always copied back to
    the instance on return, marshaling as necessary.
    If both InAttribute and OutAttribute are set, both copies are required.
    If either attribute is omitted, the marshaler can optimize by eliminating
    either copy.
    
    Found at:
    (http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpguide/html/cpconconsumingunmanageddllfunctions.asp)
    ======
    According to this the date returned from WTSEnumerateSessions function is a
    pointer to a pointer a copy of the data structure.
    Or I am wrong?
    
    If I am right, how to get this second pointer from VB .NET?
    
    Here are the API Function and structure, by definition and how I've defined
    them in my app
    
    API
    =====
    WTS_SESSION_INFO
    The WTS_SESSION_INFO structure contains information about a client session
    on a terminal server.
    typedef struct _WTS_SESSION_INFO { DWORD SessionId; LPTSTR
    pWinStationName; WTS_CONNECTSTATE_CLASS State;
    } WTS_SESSION_INFO, *PWTS_SESSION_INFO;
    
    WTSEnumerateSessions
    
    The WTSEnumerateSessions function retrieves a list of sessions on a
    specified terminal server.
    
    BOOL WTSEnumerateSessions(
    HANDLE hServer,
    DWORD Reserved,
    DWORD Version,
    PWTS_SESSION_INFO* ppSessionInfo,
    DWORD* pCount
    );
    
    =====
    
    And in my code
    ====

    Private Structure WTS_SESSION_INFO
    Dim SessionID As Int32 'DWORD integer
    Dim pWinStationName As String ' integer LPTSTR - Pointer to a
    null-terminated string containing the name of the WinStation for this
    session
    Dim State As WTS_CONNECTSTATE_CLASS
    End Structure

  - MFC >> LVS_OWNERDATA and NM_CUSTOMDRAW with CListCtrl == slow?Forgive me if this is a near duplicate post... anyway, I'm trying to use
    NM_CUSTOMDRAW to draw all the items manually in a virtual CListCtrl (a list
    control with LVS_OWNERDATA). The problem is that my method is very slow and
    sluggish feeling compared to the way windows does it, and I don't know why.
    Keeping in mind that NM_CUSTOMDRAW is only fired once per item, due to the
    LVS_OWERDATA style, rather than once per sub item, perhaps someone can
    explain to me what I'm doing wrong? Heres the code:
    
    void CMusikPlaylistCtrl::OnLvnGetdispinfo(NMHDR *pNMHDR, LRESULT *pResult)
    {
    NMLVDISPINFO *pDispInfo = reinterpret_cast<NMLVDISPINFO*>(pNMHDR);
    
    // NM_CUSTOMDRAW will take care of drawing
    
    *pResult = 0;
    }
    
    void CMusikPlaylistCtrl::OnNMCustomdraw(NMHDR *pNMHDR, LRESULT *pResult)
    {
    NMLVCUSTOMDRAW* pLVCD = reinterpret_cast<NMLVCUSTOMDRAW*>( pNMHDR );
    
    *pResult = CDRF_DODEFAULT;
    
    if ( CDDS_PREPAINT == pLVCD->nmcd.dwDrawStage )
    *pResult = CDRF_NOTIFYITEMDRAW;
    
    else if ( CDDS_ITEMPREPAINT == pLVCD->nmcd.dwDrawStage )
    {
    int iRow = (int)pLVCD->nmcd.dwItemSpec;
    
    CDC* pDC = CDC::FromHandle(pLVCD->nmcd.hdc);
    CRect item_rect;
    GetItemRect( iRow, &item_rect, LVIR_BOUNDS );
    
    DrawItem( pDC, iRow, item_rect ); // draw item [see below]
    *pResult = CDRF_SKIPDEFAULT;
    }
    
    else if( pLVCD->nmcd.dwDrawStage == CDDS_ITEMPOSTPAINT )
    *pResult = CDRF_DODEFAULT;
    }
    
    void CMusikPlaylistCtrl::DrawItem( CDC* pDC, int item, const CRect& rect )
    {
    CMemDC dc( pDC, &rect );
    
    // setup the font and highlight colors
    COLORREF bg = GetSysColor( COLOR_BTNHILIGHT );
    COLORREF text = GetSysColor( COLOR_WINDOWTEXT );
    
    // color each sub item
    CRect rcSubItem;
    dc.SetTextColor( text );
    for ( size_t i = 0; i < m_Prefs->GetPlaylistColCount(); i++ )
    {
    GetSubItemRect( item, i, LVIR_BOUNDS, rcSubItem );
    
    dc.FillSolidRect( &rcSubItem, bg );
    dc.TextOut( rcSubItem.left + 6, rcSubItem.top, _T( "Test" ) );
    }
    }
    
    Any suggestions or advice as to how to speed this up would be much
    appreciated. Thanks!

    the most efficient (i.e. fastest) way to get it? Right now I use brute
    force: I read through the entire file, counting the lines but not processing

    I'm guessing that it's possible if the capturing app can get hold of the

    defined error - Excel couldn't save the file. In fact it won't even do
    anything that involves writing to a file.
    I get a similar sort of error when trying to do it from Visual Interdev.
    I can't see what I'm doing wrong - can anyone point me in the right
    direction?
    I've tried using the P&D wizard to publish it to the server but it gave me a
    'no post info file found on server' message. I'm running XP pro
    (workstation).
