Hello.

About the minimization of the ribbon bar.
Why will not you minimize it in F1+CTRL?

I test it in Microsoft-Excel.
The ribbon bar is minimized.

How do I hide the None button on the popup CExtDateTimeWnd calendar?

Using the new feature we added to 2.82 (see our reply to Suhai Gyorgy), you will be able to remove the None button in this way

pDateTimeWnd->ModifyDropDownCalendarStyle( __EDPWS_BUTTON_NONE, 0 );

Thank you for your suggestion. We have just added the following methods to the CExtDateTimeWnd class:

virtual DWORD OnDropDownCalendarQueryStyle() const;

DWORD GetDropDownCalendarStyles() const;

DWORD ModifyDropDownCalendarStyle(
                DWORD dwRemove,
                DWORD dwAdd = 0
                );

Dear Support,

I see that you’ve introduced a new function called SetAutoSubclassChildControls in 2.80
Can you please provide the community some information about it - when to use it, how to use it, what controls it support, can it be extended etc.
I think that this is a very important function that can save a lot of tedious work for a lot of users.

Thanks.

I use PropertyGrid Control. My implementation is almost similar with your sample PropertyGrid with the stars.
- When I modify the value, the control does not display the property in bold (I checked that m_bMakeBoldModifiedValues and m_bMakeBoldModifiedNames are true done in OnInitDialog)
- When I modify the value of a multiselection, the control does not display the entered value, it stay blank.
In both cases my object is well updated.

What is wrong?
What I miss to do?

I would really appreciate your help.

Thanks in advance.

When the print preview is displayed over the property grid control, it keeps the cached set of EMF files which contains printed/previewed page images. These page images were created at a certain point of time. Then you changed property values. In this case the property grid control does not re-create print preview page images. You should close the preview and open it again to see the latest results. Is that the problem you want to tell us about?

I use CExtGridCellString and CExtGridCellColor.

I can’t give you a test program. My program is too huge.

Do you have advises for me? to check in my program.
An other information.
When I modify a value. The control displays the good value (not in bold) but the print preview, displays the old value.
Do I missed a call to synchronize or update the control?
It seems that the control is not up to date.

Thanks in advance.

Hello.

Q1,
I want to do a selection of a specific ribbon node.
Is it possible?

Q2,
I want to make a specific ribbon node non-expression.
Is it possible?

Hi,

The application on which i work is built using MFC (7.1) has many user interfaces and dialog boxes (in several hundreds).There are chains of dialog boxes one leading to another dialog box. Making code updations to each of these interfaces and dialog boxes to apply Prof UI skins is a tedious process. Do you suggest a more easier procedure (global approach) to apply Prof UI skins on several of these dialog boxes that this application hosts.

Thanks

Unfortunately we have no similar function for automatic subclassing all the windows which appear at your application’s run time. Besides, Prof-UIS does not contain extensions of some common controls like a tree view and a list view but provides its own tree grid, plain grid and report grid instead. So, generally, even if we provided some global subclassing feature like you requested, it would not replace absolutely all controls.

To make windows skinable, you should use Prof-UIS classes. You can switch from classes like CButton, CComboBox, CDialog to CExtButton, CExtComboBox, CExtResizableDialog step by step. All the dialog classes should be derived from CExtResizableDialog and all the controls on each dialog box should be subclassed with CExt*** classes. If you have a dialog with 15 controls on it and only 3 buttons on it are subclassed with CButton variables, then you should do the following:

1) Use CExtResizableDialog as the base class for your dialog instead of CDialog.

2) Use CExtButton instead of CButton for all 3 buttons.

3) Subclass all controls with Prof-UIS CExt*** classes. You can avoid creation of 12 additional member variables in your dialog class for all the dialog controls. You should simply invoke the SetAutoSubclassChildControls() method in the constructor of your dialog class.

Dear Support,

We are using your CExtReportGridWnd control and now we are testing it with many items ( around 25,000 ). For clearing the grid we are using ItemRemove(ItemGetRoot(), true, true); This takes more than 90 seconds!!! That’s way too much for clearing! Could you look into how you could speed this up?

Thank you!

This behavior is explained by how the IMalloc is implemented in the CExtAlloc class. This class implements block based memory allocations and provides a memory managed API as a IMalloc interface pointer. Each CExtGridCell*** object stored in the CExtGridDataProviderMemory<code> data provider is instantiated using a specific version of C++ new operator defined in the <code>CExtGridCell class and this operator has the IMalloc interface pointer in its parameters. The memory data provider uses this memory allocation technique to improve cell allocation time. The de-allocation time can be very fast or very slow. If the de-allocated cell object is not the last in its block of cells, then de-allocation is fast. If the cell is last in its block, then de-allocation is slow. Besides, de-allocation time very depends on whether the report grid is grouped or not.

We think the grid control with more than 3 thousand rows should be a cacheable CExtGridWnd control rather than the CExtReportGridWnd control.

25000 rows is too much for the report grid control which is designed as in-memory grid only. You should use CExtReportGridWnd::ReportItemUnRegisterAll() or CExtReportGridWnd::ReportItemUnRegisterSelection() with it rather than CExtTreeGridWnd::ItemRemove(). We can analyze the code that unregisters report grid items, but we believe its performance can be improved only in the case of unregistering the entire set of report grid items and the real performance can be not faster than CExtGridWnd::RowRemoveAll() because destruction of cell objects takes its determined time.

Hello

Will Prof-UIS2.70 be equipped with a context command tab?
http://www.yukai.jp/~ifreeta/20071217/image07.jpg

If Prof-UIS is not equipped.
When is it coped?

I want to change a color. ( RibbonBar Color Bar)

http://www.yukai.jp/~ifreeta/20071217/image01.jpg

Please teach a method to change

We modified the RibbonBar sample to illustrate how to handle color ribbon buttons. The changes are marked with the following lines in the code

// TECH_SUPPORT_BEGIN
// TECH_SUPPORT_END

I have a question about property category. When I create the control in this sequence:

Create CExtPropertyItem name "Symbol"
Create CExtPropertyItem name "Model"
Create CExtPropertyCategory name "A?" and add one item in it

I got the result in this sequence
<Property Category A?>
<Child property item of the category>
<Property item "Symbol">
<Property item "Model">

But when I change the name of the category to be "a?" (the lower case of "A"), I got this result
<Property item "Symbol">
<Property item "Model">
<Property Category a?>
<Child property item of the category>

Shouldn’t the category item be the last item no matter what the name it is? Or if I want the control to be in that way, what should I do?

Hi,

We would like to know the procedure to apply prof UI skins to an application that makes use of MFC 7.0. What are the code modifications that are required within our application in order apply prof UI skins. Is the procedure same as applying different themes of Prof UIs.

One particular clarification requested is, if the apllications main interface hosts many controls (such as MFC list boxes & list controls which do not have any relation with the prof UI control ) what would be the procedure to apply the prof UI skin.Should these controls also be derived from prof UI controls ? If so, does prof UI provide any customized controls for List Control, Views, toolbars which i am unable to find in prof UI library.

Otherwise, is the applying of prof UI skins procedure independent of the controls that user interface hosts ?

Thanks

Help me. please

Thank you very much
I solve this problem.

I tried to create a property category, CExtPropertyCategory object. But there is no any category in my property grid control. Here are my codes:

CExtPropertyGridComboBoxBar * pCombo =
        STATIC_DOWNCAST(
        CExtPropertyGridComboBoxBar,
        GetChildByRTC( RUNTIME_CLASS(CExtPropertyGridComboBoxBar) ) );

CExtPropertyStore* pPropertyStore = new CExtPropertyStore( pConfiguration->Name().c_str() );

CExtPropertyCategory* pCategory = new CExtPropertyCategory( L"test" );
    pCategory->DescriptionSet(    _T("test properties") );
    VERIFY( pPropertyStore->ItemInsert( pCategory ) );

pCombo->PropertyStoreInsert(pPropertyStore);
pCombo->SetCurSel(0);

I tried to insert CExtPropertyItem object, and the propery grid can show the items. Please tell me how to show a property category?

We confirm the property categories without child property values are not displayed in the property grid control. This is by design and we think this is correct.

Hi,

I want to join particulars cells of a grid. I have used your sample "how to join cells or headers".
Your sample works correctly but I have a problem in my application.
The grid is displayed on a view and if one of the two cells (begin or end join cell) is hidden by reduce view size the join is not done.
This is beacause method "GridCellRectsGet" calculate a set of rectangle for VISIBLE grid cell.
So how can I resolve my problem.

Regards,

hi

To enable CExtComboBox filter wnd, I do this (ProfUIS 2.81, Visual 2005):

    m_wndCombo.m_bEnableAutoComplete = true;
    m_wndCombo.m_bEnableAutoFilter = false;

(see your sample project ’TextComboGrid’)

-> pb in exthook.cpp when I left click on the non client area of the combo parent dialog:

exthook.cpp: line 236: function HookChainsWindowProc: 0xC0000005: access violation
(The hWndHooked parameter is 0xfeeefeee, which is not a valid HWND)

You can easily reproduce the pb with TextComboGrid project.

Have you a solution ?

The CExtComboBox class is no longer based on CExtHookSink. This problem and several other issues were fixed. Here is the latest source code of the combo box:

We believe there must be some differences between how the RibbonBar sample and your application are initialized, which causes an incorrect frame window region. Could you send us your test project so we will find out what is wrong?

The question 1

Set the following order,
g_PaintManager.m_bIsWin2000orLater = false;

The application falls when I click here.

We have just added a new FAQ article in response to your question:

How to disable fade-out menu animation in CExtRibbonBar and CExtRibbonPage?

You should not modify g_PaintManager.m_bIs***. They affect which APIs are invoked when the app is running on different Windows OS versions.

The ribbon file button is a kind of ribbon gallery button. So, you should override the following virtual method in your CExtRibbonBar-derived class to catch the item selection in the ribbon gallery control

      virtual void OnRibbonGalleryItemSelEndOK(
            CExtRibbonGalleryWnd & wndRG,
            CExtRibbonGalleryPopupMenuWnd * pGalleryPopup,
            CExtRibbonButtonGallery * pRibbonGalleryTBB,
            CExtToolBoxWnd::TOOLBOX_ITEM_DATA * pTBCI
            );
