I create a listview with 3 columns. First column show text, and second, third show bitmap. It's OK under win2k and winxp, but under win9x, text show in secord and third column too, why?

I had about 100 rows with about 4 bitmaps for each row.
Someone suggested using a DIB instead of DDB. I'm not real knowledgable about these but it might be an improvement.

Are you looking for a cool tree control?

Check this out: http://www.exontrol.com/sg.jsp?content=products/extree

Features include: 

ActiveX hosting, events from contained components are fired through to your program using the exact same model used in VB6 for components added at run time, data bounding, multiple columns, and more

I don't know if this is a bug or me doing something wrong. 

I'm trying to set the text in the second column for child items only.

I'm using a nested while loop which does the correct insert for all child nodes on the call m_treeCrtl.SetItemText(item, subitem, text) 

but,when the loop is done, the very FIRST item inserted has 2nd column text of the last item inserted (which is a subitem).  Follow this?

Again, I'm putting text where the check boxes are in the sample but only for the child 'nodes'. And the problem is that the first parent node has the text of the last subitem when it should have nothing.

If I do this to clear it:

m_treeCtrl.SetItemText(0, 1, " ");

m_treeCtrl.RedrawWindow();

it clears it, 

but this does not:

for(int x = 0; x < nNumParentEntries; x++){

	nItem = m_treeCtrl.GetNextItem(x,LVNI_ALL); 

	m_treeCtrl.SetItemText( x, 1, " ");

}

m_treeCtrl.RedrawWindow();

The former does what I need to fix it but not sure what is happening.  Sorry this is so long.

Can't add data to columns in top level rows

Hi,well I made my own solution. It is actually very simple.

Steps for GridCtrl.cpp:

 1. In the constructor CGridCtrl::CGridCtrl(int nRows, int nCols, int nFixedRows, int nFixedCols)

	add the following code :

    // To double click on the grid an send a message to the owner of the grid

	// the owner first has to tell the grid it wants to receive the message

	// This is done by this member var which is set by a helperfunction.

	// See for the implementation CGridCtrl::OnLButtonDblClk

	m_bReturnDblClickMsg = FALSE;

 2. In function void CGridCtrl::OnLButtonDblClk(UINT nFlags, CPoint point)

    else if (m_MouseMode == MOUSE_NOTHING)

	{

	    if (m_LeftClickDownCell.row >= m_nFixedRows && 

		IsValid(m_LeftClickDownCell) &&

		m_LeftClickDownCell.col >= m_nFixedCols)

	    {

		OnEditCell(m_idCurrentCell.row, m_idCurrentCell.col, VK_LBUTTON);

	    }

	    else if (m_bListMode)

	    {

		CCellID cell = GetCellFromPt(point);

		if (!IsValid(cell)) return;

		if (cell.row >= m_nFixedRows && cell.col < GetFixedColumnCount())

		    OnEditCell(cell.row, cell.col, VK_LBUTTON);

	    }

	    // *****************

	    // The following code is new

	    if ( m_bReturnDblClickMsg )

	    {

		CWnd *pWnd = this->GetOwner();

		if ( IsWindow(pWnd->GetSafeHwnd()) )

		    pWnd->SendMessage( WM_DOUBLECLICKGRID ); 

	    }

	    // *****************

	}

	CWnd::OnLButtonDblClk(nFlags, point);

}

Steps for GridCtrl.h:

1. Add a #define WM_DOUBLECLICKGRID WM_USER+1

2. Add a public helperfunction to CGridCtrl 

	 void SetReturnDblClickGridMessage( BOOL bValue ) { m_bReturnDblClickMsg = bValue; }

3. Add a protected memberbar BOOL m_bReturnDblClickMsg;



Okay and now in you code that uses the grid:

1. Add ON_MESSAGE(WM_DOUBLECLICKGRID, OnDblClickGrid) to your dialog's/view's BEGIN_MESSAGE_MAP

2. Add function LRESULT CYourView::OnDblClickGrid(WPARAM wParam, LPARAM lParam)

   {

	  OnModify();

	  return 0L;

   }

2. Add to header : afx_msg LRESULT OnDblClickGrid(WPARAM wParam, LPARAM lParam);

3. And finally let the grid know you want to be able to doubleclick a row by
m_Grid.SetReturnDblClickGridMessage( TRUE );

That's all.

Danny
