Problem in using Microsoft Agent in VB

Posted on 2001-06-26

I have written an application in VB 5 where Microsoft Agent (Genie) is used.
I am using a menu and toolbur button to show or hide the agent with following

Private Sub mnuViewAgent_Click()
   mnuViewAgent.Checked = Not mnuViewAgent.Checked
   If mnuViewAgent.Checked = True Then
   End If
End Sub

Private Sub tbToolBar_ButtonClick(ByVal Button As ComctlLib.Button)
   Select Case Button.Key

      Case "...."
                  ' Code for other toolbar button goes here    
      Case "Agent"
   End Select
End Sub

I am also using a command button for the agent to speak with following code:

Private Sub cmdSpeak_Click()
      If mnuViewAgent.Checked = False Then
      End If
      Set MyRequest = MyAgent.Speak(strSpeak) ' Some string is set in other part
      'To prevent the application from continuing
      'until the agent completes its task
      Do Until MyRequest.Status = 0
      If mnuViewAgent.Checked = False Then
      End If
End Sub

Problem is the application is showing some erratic behaviour (see
sequence of operation):
Agent is not shown (not appearing),
mnuViewAgent or corresponding toolbar button is clicked,
mnuViewAgent is checked and Agent is shown,
some other actions (not related with mnuViewAgent, corresponding toolbar buttonm
and cmdSpeak) are done,
munViewAgent is found to be unchecked, though Agent is still shown (visible).

This is what you may want to do in the event of having some funny problems:

- After each case in your toolbar event, add the line:
Exit Sub

- After this line:
mnuViewAgent.Checked = Not mnuViewAgent.Checked

Add a message box to test the value of mnuViewAgent.Checked and see if it works fine.

- Make sure that you do not have any code in the Form_Load event of the form, MyAgent which may cause the for to 'not showing'. Make sure also that the event does not change the value of mnuViewAgent

- For your cases:
Case "Agent"

Make sure that there isn't any repetition of it earlier on or it would execute the earlier case and ignore the later case.

- Make sure that you didn't use any timers to call any _click event of any controls.

That's it and good luck!

PS. By the way, is MyAgent a control or a form?  If it's a control, shouldn't there be a 'Visible' property instead?

Hey Bhowel,

I have develolped with MS Agents before... but I am not sure what you are trying to accomplish...

Thanks. I found the bug from your hint. Actually I had some unwanted code in Form_Paint event which was unchecking the mnuViewAgent.

MyAgent is an ActiveX control. I am using this code
In General section:
Dim MyAgent As IAgentCtlCharacter

In Form_Load:
'Load character data into the application
    Agent1.Characters.Load "Genie", _
    Set MyAgent = Agent1.Characters("Genie")
In case you have not yet tried Microsoft Agent, you can down load the same from following site:   And add Microsoft Agent Control in Project>Components                  It's fun.
What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

Glass cookie,
       I am sorry. Yes,  it's a dead link. However, it still gave me further links to connect to Microsoft Agent download site.
If you are still not through you may try the following link:
