Xceed SmartUI

KeyPress event is not being raised.

Xceed admin — Fri, 10 Oct 2008 14:58:41 GMT

SmartUI manages some keys events by its own in order to simplify your code. If you need full access to keys events, you need to implement a keyboard hook (see attachments).

How do I enable Combo SmartItems to have a drop down menu?

Xceed admin — Fri, 10 Oct 2008 14:57:55 GMT

There is not a direct method to do this, but the following code can be used to achieve the desired results:

SmartUI1.SetFocus
SmartUI1.SmartItems(1).EnsureVisible
SmartUI1.SmartItems(1).Selected = True
SendKeys "%{down}", T

Error: "The current version of SmartUI can't be distributed"

Xceed admin — Fri, 10 Oct 2008 14:57:31 GMT

The License method must be called in order to license your copy of SmartUI. To register all SmartUI controls being used in your application, the License method should be called in your Sub Main or in the main form's Initialize method.

Private Sub Form_Initialize()
Dim result As Boolean

result = XceedSmartUI.License( "your license key" )

If Not result Then
Call MsgBox( "Licensing failed!" )
End If
End Sub

The License method is available as of version 2.0.100 of SmartUI. You can download the latest version from the Update Center.

How do I dynamically add and removing items to and from a list?

Xceed admin — Fri, 10 Oct 2008 14:56:51 GMT

Create a blank VB project and add three controls to it:
- A button with the name btnAdd.
- A button with the name btnRemove.
- An edit control with the name txtNewItem
- A SmartUI control called SmartUI1

Then, in the button add event, you can use the following code to add an item to the list:

Private Sub btnAdd_Click()
    SmartUI1.SmartItems.Add , , txtNewItem.Text, ListItemFullRow
End Sub

Private Sub btnRemove_Click()
    If Not SmartUI1.SelectedItem Is Nothing Then
        SmartUI1.SmartItems.Remove (SmartUI1.SelectedItem.Index)
    End If
End Sub

How do I select a subitems key in a ComboBox?

Xceed admin — Fri, 10 Oct 2008 14:56:19 GMT

There is an example in lesson #16 that demonstrates how this can be done. The code contains the following:

Private Function GetItemSelected(Item As BoWSmartUI.SmartItem) As BoWSmartUI.SmartItem

Dim SubItem As SmartItem

For Each SubItem In Item.SubItems
    If SubItem.Caption = Item.Value Then
        Set GetItemSelected = SubItem
        Exit Function
    End If
Next SubItem
End Function

Checked property displays incorrectly in a MenuGroup.

Set the ImageWidth property to 16 pixels:

smMenu.ImageWidth = 16

License information for this component not found.

Xceed admin — Fri, 10 Oct 2008 14:54:54 GMT

Private Sub Form_Initialize()
    Dim result As Boolean

    result = XceedSmartUI.License( "your license key" )

    If Not result Then
        Call MsgBox( "Licensing failed!" )
    End If
End Sub

The License method is available as of version 2.0.100 of SmartUI. You can download the latest version from the Update Center.

Is it possible to retrieve the text in a TextBoxTool SmartItem?

Xceed admin — Fri, 10 Oct 2008 14:10:43 GMT

The TextBoxTool's Text property represents the TextBoxTool's label and not the text it contains. Therefore, in order to retrieve the text in a TextBoxTool SmartItem, you must pass by the TextBoxTool's virtual textbox. For example:

Dim text As String = textBoxTool1.VirtualTextBox.Text

If you want to know when the TextBoxTool's text changes, you can use the virtual textbox's TextChanged event:

AddHandler textBox1.VirtualTextBox.TextChanged, AddressOf Me.ToolTextChanged

Private Sub ToolTextChanged( ByVal sender As Object, ByVal e As EventArgs )
' Code goes here
End Sub

Version 3.1 of SmartUI for .NET is required.

In VB6, I get the permission denied error when trying to compile. Why?

Xceed admin — Fri, 05 Sep 2008 19:16:49 GMT

There are two reasons why you get this error.

First, if you have more than one of the same component .dll registered on the system, when you try to compile you will have a Permission denied message box.

Here is what you need to do.

1) Go in the Project Menu and down to references. Remove any references to your Xceed component.

2) Save and close your VB application.

3) Unregister any of the component .dll you might have on your system (We strongly suggest that you use the Windows Search to make sure not to miss any). To unregister the DLL use Regsvr32 -u "Path of the dll"

4) Register the DLL you wish to use in your application and remove any other of the component .dll you do not wish to use.

5) Open VB, add the reference and you should be on your way.

Second, you have not installed the package, but simply copied directly on the system a version of the component you want to use, and registered it manually. Some keys need to be set in Windows registry, for the way VB loads components makes our components verify the licensing at compile. To resolve this issue, unregister the dll you installed manually, delete it, and install the package, which will set the registry properly.

How do I improve the performance of my zip file manipulation?

Xceed admin — Fri, 05 Sep 2008 18:52:40 GMT

When performing multiple operations on a zip file, you can increase performance by placing the code that accesses/ modifies the zip file between calls to the ZipArchive's BeginUpdate and EndUpdate methods.

When BeginUpdate is called, all modifications to the zip file are "queued" until EndUpdate is called. This means that the zip file will be modified only once rather than once for each operation.

Images retrieved from an ImageList are not displayed properly.

Xceed admin — Fri, 05 Sep 2008 18:49:59 GMT

This is a known issue. The Microsoft ImageList does not support semi-transparent images.

As a workaround, assign the image you want to use directly to the SmartItem's Image property.

No images with external imagelist with Windows XP.

Xceed admin — Fri, 05 Sep 2008 18:41:28 GMT

We have studied the problem regarding SmartUI images problem under Windows XP. The tests were completed with Windows XP Build 2600 (RTM).

Here are our conclusions:
* SmartUI works well when using it own images

* SmartUI works well when using images from another SmartUI

* SmartUI does not work well when using images from an MS ImageList version 5.0 (COMCTL32.OCX).Version 6.0of COMCTL32.OCX is confirmed by Microsoft to correct the issue.

The problem is due to the ActiveX control provided with Windows XP (mscomctl.ocx). The handle returned by the imagelist (ImageList1.hImageList) is not correct.

The possible workarounds are:

* Use version 5.0 instead of version 6.0
* Use SmartUI's own images

What programming languages are supported by SmartUI?

Xceed admin — Fri, 05 Sep 2008 18:40:45 GMT

Due to some specific problems linked to the Windowless and WYSIWYG features, SmartUI currently can only work with a Visual Basic 6 container.

I would like to know what combinations of SmartUI components are possible?

Xceed admin — Fri, 05 Sep 2008 18:40:20 GMT

In general, all combinations of SmartUIs are possible except in menus, where you can only add "standard" menu items

Adding a text box into a SmartUI menu.

Unfortunately it is not possible to add a text box to a SmartUI menu.

Creating an outlook bar on a MDI form.

Xceed admin — Fri, 05 Sep 2008 18:37:02 GMT

Put all SmartUI controls (Main SmartUI and children) in a PictureBox, and put the PictureBox inside the MDI Form. Please make sure to put the main SmartUI in the background and the children on top (ZOrder).

Collapse/expand events do not fired when a (sub) menu is open

Xceed admin — Fri, 05 Sep 2008 18:36:34 GMT

You can dynamically create the menu (like in lesson #15) in the BeforeDropDown event. But you must create all menu items and children, as there are no events when sub-menus are opened.

When subclassing a form containing a SmartUI the application crashes. Why?

Xceed admin — Fri, 05 Sep 2008 18:35:59 GMT

In order to be able to subclass the form, you must make your subclass after SmartUI is loaded, and then unsubclass before SmartUI is unloaded. For this, you can start subclassing in the Form_Paint event, and unsubclass in the Form_QueryUnload event.

Adding an icon to the caption of a SmartUI control

Xceed admin — Fri, 05 Sep 2008 18:35:17 GMT

To do this, you must use two SmartUI controls. One control configured as a Label positioned above the second control.

Handpointer property cannot be set on a MDI form

Xceed admin — Fri, 05 Sep 2008 18:34:50 GMT

First put the SmartUI inside a PictureBox. Next put the PictureBox inside the MDI Form. The Handpointer property should now work correctly

How do I use the ProgressBar without calling DoEvents?

Xceed admin — Fri, 05 Sep 2008 18:33:43 GMT

Put the SmartUI into a PictureBox and call Picture1.Refresh or Call Form1.Refresh if SmartUI is directly on the form.

How do I capture right click events?

Xceed admin — Fri, 05 Sep 2008 18:33:17 GMT

You can use either the MouseDown or MouseUp event to determine the button pressed. Inside these events, you can use the SmartUI.HotItem property to get the item selecte

Application has generated an exception that could not be handled

Xceed admin — Fri, 05 Sep 2008 17:45:47 GMT

You also need to register the DLL for the ActiveX component. You can set your installer to automatically register the DLL or use the "REGSVR32" command to manually register on the local machine.

I am trying to instantiate my Xceed control, however Visual Basic is return an error saying "Invalid use of New keyword". Is it possible to instantiate the control?

Xceed admin — Fri, 05 Sep 2008 16:57:53 GMT

Yes, it is possible to instantiate the control. Visual Basic is a bit "touchy" when it comes to adding references. What you will need to do is remove the Xceed Control from both your list of References and Components. Once this is done, add it ONLY to your list of references.
