An Outlook 98/2000 Style SuperGrid Report Control that tries to overcome some of the weaknesses of other implementations.

Sample Image

Introduction

This ReportCtrl control is an Outlook 98/2000 style SuperGrid control. I've seen many implementations, most of them based on the standard CListCtrl. All implementations have their specific weaknesses. This implementation tries to overcome some of the weaknesses, although for some purposes it may introduce others.

The documentation is sparse, because I do not have much time to write documentation. However, the included demo is a great help in understanding how to use the features of the control and many features are demonstrated in a practical manner. The interfaces of the controls highly resemble the interfaces of similiar MFC controls, like the list control and header control. So, for the more experienced MFC coder, it should not be a big problem to understand how to use the control in their own projects...

GeneralResizing misbehavior Pinmemberhanryz11-Dec-03 22:10 
Hi all,
 
I'm using the SuperGrid Report Control written by Maarten Hoeben and appreciate this software as very multifunctional and convinient as well. But since introduction we have experienced a little trouble with it. I'm wondering why the bug i'm going to describe below hasn't been reported yet.
 
Bug description:
 
The thing is, when you are resizing the header in the list control(CFlatHeaderCtrl class) too fast, the software starts recognizing your action in a incorrect way. Actualy, it places itself in the drag and drop mode as though you're going to change column's places. This is an ugly bug because after it is occured, the headers jump out of the grid and become independent from it. One has a little chance to get it in proper position again.
 
Suggested solution to eliminate the bug
 
In the class CFlatHeaderCtrl, there is a function called OnMouseMove. Everything one needs, is to check m_bResizing flag when the software means it should start in the drag'n drop mode. The Author already sets und resets that flag properly (I suppose Smile | :) ). Here's the code of the OnMouseMove routine where the bug is not present anymore:
 
void CFlatHeaderCtrl::OnMouseMove(UINT nFlags, CPoint point)
{
if(m_bButtonDownOnItem && m_nClickFlags&MK_LBUTTON && m_iHotIndex>=0)
{
if(m_bResizing)
CHeaderCtrl::OnMouseMove(nFlags, point);
 
if(m_hdhtiHotItem.flags&HHT_ONHEADER)
{
if(m_bDragging)
{
..............
..............
}
else if(GetStyle()&HDS_DRAGDROP && m_bResizing == FALSE) // the only change (hanryz)
{
.............
.............
}
}
}
 
That's it.
 
The Author's opinion to this solution would be appreciatedSmile | :)
 
So long.
