MessageBox Visual Studio Add-In

Environment: Visual Studio 6

How many times have you had to go through the same gyrations to create a message box? Is it the first argument or the second that's the title as opposed to the text. What are the exact constants again for an OK button and a Cancel button? What are the valid return values? Well no more! This very useful add-in saves you from having to remember that from now on! Using this add-in, you can visually set any of the following:

  • Icon type
  • Buttons
  • Caption (notice the built-in values provided for you!)
  • Text message
  • Modality
  • Default button
  • You can even specify the conditional expression!
When you're finished selecting your settings, simply click the "Copy to Clipboard and Close" button. You'll be returned to your previous source window. Just paste the code from the clipboard and you're done!


Using the settings shown in the figure above, the add-in produced the following!
if(MessageBox(_T("This is an Error Message !!!\nReturn ?"), 
               == IDNO)

Installing the Add-In

To install the add-in, follow these steps:
  1. Download the DLL (remember to unzip the file) or download the source and build the DLL
  2. Copy the DLL to the Visual Studio AddIn folder (the default location is the

  5. Click the Add-ins and Macro Files tab
  6. Check the "MsgBox Developer Studio Add-In" add-in
  7. Now you can assign it to a key or place it on a toolbar as you like

  • Nice Work, I have an improvement

    I have a minor improvement that handles the if-then-else case better if the user chooses Abort-Retry-Ignore or Yes-No-Cancel. Replace the CMsgDlg::CreateCode function with the following code.

    Thanks again,

    Nathan Schultz

    void CMsgDlg::CreateCode(CString& csResult)
    UINT uiStyle=0;
    CString csCode(_T(""));
    CString csStyle(_T(""));
    CString csSpace;

    SetSymbol(uiStyle, csStyle);
    SetButtons(uiStyle, csStyle);
    SetDefButton(uiStyle, csStyle);
    csStyle.SetAt(0, ' ');

    case bcNo:
    csSpace = _T(" ");

    case bcIf:
    case bcIfThenElse:
    csSpace = _T(" ");
    if (m_iButtons == bbAbortRetryIgnore || m_iButtons == bbYesNoCancel)
    csCode += "int l_nRet = ";
    csCode += _T("if(");

    case btGeneric:
    csCode += _T("::MessageBox(NULL, ");

    case btCWnd:
    csCode += _T("MessageBox(");

    case btAfx:
    csCode += _T("AfxMessageBox(");

    csCode += _T("_T(\"");

    CString csMsg(m_csMsg);
    csMsg.Replace(_T("\r\n"), _T("\\n"));
    csCode += csMsg;

    csCode += _T("\")");

    csCode += _T(", ");

    if(m_iType != btAfx)
    csCode += _T("\r\n") + csSpace;
    csCode += _T("_T(\"");

    csCode += m_csCaption;

    csCode += _T("\"),");

    csCode += _T("\r\n") + csSpace;
    csCode += csStyle;
    csCode += ')';

    int iReturn=0;
    CString csReturn(_T(""));
    SetReturn(iReturn, csReturn);

    if(m_iCondition == bcIfThenElse && (m_iButtons == bbAbortRetryIgnore || m_iButtons == bbYesNoCancel))
    csCode += _T(";\r\nif (l_nRet ");
    csCode += _T("\r\n") + csSpace;
    csCode += csReturn;
    csCode += _T(")\r\n{\r\n}");

    if(m_iCondition == bcIfThenElse && (m_iButtons == bbAbortRetryIgnore || m_iButtons == bbYesNoCancel))
    csCode += _T("\r\nelse if (l_nRet == )\r\n{\r\n}");

    if(m_iCondition == bcIfThenElse)
    csCode += _T("\r\nelse\r\n{\r\n}");
    csCode += ';';

    csResult = csCode;
