This article was previously published under Q215390



SYMPTOMS
In an eVB/VBCE project, when you change the focus from the Grid control to any of the following controls, the focus might not change until you click the other control twice:
 * CommandButton
 * ListView
 * PictureBox
 * TabStrip
 * TreeView

This behavior occurs both in emulation and on the remote device. The expected behavior is that the focus changes after the first click to the new control.



RESOLUTION
This behavior tends to occur when other screen-related events are involved, such as when you use the message box in the code example below. If other screen-related events do not occur, the focus events should occur as expected.



STATUS
Microsoft has confirmed that this is a bug in the Microsoft products that are listed at the beginning of this article.



MORE INFORMATION
This section shows how to create a sample project that demonstrates this behavior.

Steps to Reproduce Behavior
 Create a new Windows CE project in either Visual Basic or eMbedded Visual Basic. Form1 is created by default. Add the following controls to Form1:  CommandButton Grid ListView PictureBox</li> TabStrip</li> TreeView</li></ul>

</li>  Copy the following code to the Form1 code window: Option Explicit

Private Sub Command1_GotFocus MsgBox "Command" End Sub

Private Sub GridCtrl1_GotFocus MsgBox "Grid" End Sub

Private Sub ListViewCtrl1_GotFocus MsgBox "ListView" End Sub

Private Sub PictureBox1_GotFocus MsgBox "PictureBox" End Sub

Private Sub TabStrip1_GotFocus MsgBox "TabStrip" End Sub

Private Sub TreeViewCtl1_GotFocus MsgBox "TreeView" End Sub

</li> Press the F5 key to run the project. Set the focus by clicking the grid control. A message box appears to confirm that the GotFocus event executed. Click OK to close the message box. Click on another control.

BUG: The GotFocus event for that control does not execute until you click the control for the second time. The expected behavior is that the GotFocus event executes on the first click.NOTE: If the code above is modified to avoid other screen activities, the focus events should occur as expected. For instance, add a Listbox to the form and change the instances of "MsgBox" to "List1.AddItem" (without the quotes). The focus changes should occur as expected and be correctly reflected in the Listbox.</li></ol>
