Dear Support,

We are using this function, and even though we already found few bugs there that you fixed, this function still does not work, ann also crashes our application very often.

We notice two bugs there:

1) If you show & hide several times in different orders (of nodes that have childrens), it start to switch nodes locations in the tree, which it should not.

2) After these switches accure, the next time you try to show & hide one of these nodes that were switched, the application crashes.

For us this function is a must - please ask your QA team to explore this functionality and fix it ASAP, as we have to use this function a lot.

Thanks,

Ron.

Hello.

I am not non-visible in an item.

I want to make an item non-display.

Is it unrealizable?

Hello.

With the following commands, a selection does not move either.

I am troubled. 

if ( sItemText == "top level item 1" ){

    m_wndTree.FocusItem( hti , true, true , true );

    m_wndTree.Invalidate();

}

Thanks,

Could you modify our test project and make it reproducing this problem and send it to us?

Hello.

I described a focus in the following points.

        Walk( hti, s, nIndent + 1 );

        if( sItemText == _T("top level item 1") )

        {

            m_wndTree.SetFocus();

            m_wndTree.FocusItem( hti, true, true, true );

            m_wndTree.Invalidate();

        }

    }

When a focus moves to other control, a focus of tree disappears.

I want you to teach the method how a focus does not disappear.

Hello.

I want to always display focuses.

Please answer it.

Thanks,

I decide to display an icon in substitution for focus drawing.

We have tested this issue in the same sample application:
<pre>void CTreeTextDlg::Walk( HTREEITEM htiParent, CString & s, int nIndent /* = 0*/ )
{
HTREEITEM hti = m_wndTree.GetNextItem( htiParent, ( htiParent == NULL ) ? TVGN_ROOT : TVGN_CHILD );
for( ; hti != NULL; hti = m_wndTree.GetNextItem( hti, TVGN_NEXT ) )
{
CString sItem, sItemIdent, sItemText = m_wndTree.GetItemText( hti );
for( int i = 0; i < nIndent; i ++ )
sItemIdent += _T(" --> ");
sItem.Format( _T("%s%s\r\n"), LPCTSTR(sItemIdent), LPCTSTR(sItemText) );
s += sItem;
Walk( hti, s, nIndent + 1 );

if( sItemText == _T("top level item 1") )
{
m_wndTree.FocusItem( hti, true, true, true );
m_wndTree.Invalidate();
}
}
}
<pre>The item focus feature is working ok.

Hi,

We recently upgraded from Prof-UIS 2.83 to 2.84.  There appears to be a bug.  When you change a combo box item in a property grid (CExtGridCellDropListComboBox), CExtPropertyGridCtrl::OnPgcInputComplete is not called.  This has broken all combo box items in the property grid in our application.  This code was calling & working fine in 2.83.

Any chance of a workaround or fix here?

Dear Support,

Our application catches the window’s WM_SETFOCUS event to know when focus/active view has changed in an MDI application.

We notice that in 2.84, when swithching the views from the CExtTabMdiWnd the events are not received in the views.

Can you please fix it ASAP - This is a major item we must have before swithcing 2.84 to production.

Thanks,

Ron.

IMPROTANT - the event is not received at the view if a control-bar have the focus. It seems that the control-bar has the focus, so the new view never gets focus, so the event is never called.

If there is any way of getting events or over-ride the CExtTabMdiWnd for knowing when the user switched view it might be enough for us to bypass this problem.

From root, I want to examine all HTreeItem recursively.

I ask for a sample code.

Thanks,

Hello.

Thank you.

Clicking on a column header to sort no longer works.  This bug is present in my application as well as in ReportGrid demo.

Please take a look.

Thanks, Dave

Dear Support,

I see you used this function is the caption tip sample. I could not find any documentation about it, please explain where and how to use it.

Thanks,

Ron.

I saw that you used this template on a control bar to get cool tips.

I could not find any documentation of it - can you please explain when and how to use it?

Thanks,

Ron.

You are right. It’s not documented yet. Thank you.

This small tooltip class displays the CExtPopupMenuTipWnd tooltips over any other window. It uses the standard MFC’s CWnd::OnToolHitTest() method to get the tooltip information. In simple words, this template class replaces standard tooltips which window would like to display with Prof-UIS tooltip.

Thanks,

Can it be added to any CWnd derived?

I see this enum and functions:

    enum e_ui_scaling_type_t
    {
        __EUIST_X		   = 0,
        __EUIST_Y		   = 1,
        __EUIST_Z		   = 2,
        __EUIST_MIN_VALUE   = 0,
        __EUIST_MAX_VALUE   = 2,
    };
    virtual bool UiScalingIsEnabled(
        e_ui_scaling_type_t eUIST
        ) const;
    virtual INT UiScalingDo(
        INT nValue,
        e_ui_scaling_type_t eUIST
        ) const;

Thanks,

Ron.

I have a grid that has a date-time field.

I need the ’Text Filter’ sub-menu to contain only two options - After Date and Before Date, and that the edit box will be a date-time control and not edit-box. I also need to change the text of the sub-menu from ’Text Filter’ to ’Range Filter’

Is this possible? for me these requirements are a must, and if they are not implemented I’ll have to re-code all the filtering myself, which seems pitty, as the mechanism is already there.

Thanks,

Ron.

We can regard your question a feature request. The text filter sub menu contains text based filtering options only without care about real data type.

Hi,

In the Obsidian theme, when a button is pressed and the focus dots are displayed, for some reason some of the dots are drawn in a complete different color, as you can see in this capture:

And blown up:

We get complaints about it from our customers... can this be fixed so that the dots wont blend with the back-color? we realy do not need this purple dots...

Thanks,

Ron.

I have a tree grid that crashes each time A node is going to be displayed.

I see that in CExtTreeGridDataProvider::_Tree_MapRowToCache, this line:

CExtTreeGridCellNode * pNode = m_arrGridVis.GetAt( nRowNo );

returns NULL, even though the row line is valid. The entry is within the array, because the array size is bigger then the nRowNo, so, for some reason the array contains NULL entries - how can this be?

Please note that the same think does not happen in 2.82.

Please fix.

Thanks,

Ron.

We need your help in reproducing this crash.

My application (which now incorporates Prof-UIS) causes Windows to display an error message whenever a file of its type is double clicked on. The error message says: "Windows cannot find ’[doc file]’. Make sure you typed in the name correctly, and then try again. To search for a file, click the Start button, and then click Search." Despite the error message, the document opens correctly.

I have not yet determined the exact cause of the error, but it looks like Windows generates the message after pMainFrame->LoadFrame(IDR_MAINFRAME).

At first I assumed the problem had to do with my application, but after looking at the MDIDOCVIEW sample application, I found that it does exactly the same thing. If you save a document, close the application, and then double click on the document, the same error message is generated.

Any idea what is causing this error?

If it makes a difference, I’m running on a dual core Windows XP machine.
