The Problem This small commandline utility will solve a problem often found when moving Visual C++ projects between computers. Often I need to take MSVC5 projects with me between different computers. But sometimes, when a project has been moved from one computer to another, strange thing will happen , when you try to compile it.When […]

(Designed and developed by Shekar Narayanan) I have developed this Class Generator after using the CRecordset for quite some time. CRecordset is great but it has lot of limitations and is SLOW. Most of the time, I had to display thousands of records in a list view. Using the CRecordset, it takes a lot of […]

This example demonstrates the various aspects of changing the text of the tool tips at runtime. It is far from perfect but does the job and has been stable in several application where I use it. Need to override the OnToolTipText() virtual afx_msg BOOL OnToolTipText(UINT nID, NMHDR* pNMHDR, LRESULT* pResult ); Add message handlers for […]

This class shows how I went about implementing my own tooltip window when I had trouble getting the standard Tooltips to provide the functionality I wanted. The attached code readily demonstrates the concepts of defining your own windows for use with MFC, installing keyboard hooks, and handling the correct clean-up of the system on completion […]

  Download Source Code and Example Introduction Can we do something to make a tooltip attracts the user attention on it a little more? If the tooltip plays a sound when it pops up then maybe the things should get better. Well, this is a small class called CWavTipCtrl that inherits from CToolTipCtrl and adds […]

Download Source Code The CToolTipEx class is a extension of the MFC CToolTipCtrl control. When Microsoft c reated Internet Explorer 4, they also added many new functions and capabilities for CToolTipCtrl. Unfortunately, they have not added these to the CToolTipCtrl class yet. This class wraps all the new procedures in an easy to use and […]

Tooltip Handler (located in TooltipHandler.h/cpp) is a utility function that handles MFC bug – disabled controls don’t show tooltip. All that the programmer has to do is overwrite PreTranslateMessage() of the dialog box class, and to pass to the handler an array of the controls that may be disabled, a number of controls in the […]

As an alternative to the method suggested by Ran Almog, you can replicate MFCs fix in the dialog’s PreTranslateMessage override. The MFC code to look at is in the function RelayToolTipMessage in the file TOOLTIP.CPP. This method has the advantage that it uses the tooltip itself to find the child window, the relevant CToolTipCtrl function […]

Download demo project. I have had many, MANY questions asking how to use my MFC grid control in a view instead of in a dialog, so hopefully this will help. The easiest way as I see it is as follows: Add a member variable of type CGridCtrl* to your view class: CGridCtrl* m_pGrid; Initialise this […]

 Download Source Code and Example   This is MFC version of grid I originally wrote in OWL. All about grid is in PageWnd.h (cpp) file (which does not mean it is too long). CPageWnd provides public members for getting/setting cell text, color, alignment and font, column width, row height and similar. It is easy to […]

 Download Source code and demo project This is a previous version of Chris Maunders MFC Grid control (version 1.03) with a minor bug fix and several improvements. First a bug fix: In some situations I have managed to edit cells in fixed column, so I added a line in OnEditCell() Event handler to prevent it: […]
