Dynamic Data Exchange LinkExecute

[vhassan]

hi Previously I was using frmStart as my startup object and in Form_Load I was calling LinkExecute if my frmStart is already loaded. Now I have changed my startup object and using Sub Main() to show or hide frmStart. Problem is that now when I call LinkExecute in the frmStart Load the execution goes fine but Object gets unloaded automatically. I get Error '364' After LinkExecute I have Unload Me command but control never reaches there. please tell me how to avoid the "Object was unloaded" error. Thanks.

I have no clue what you're talking about... Is this a VB6 app or VB.NET?? What are you doing with "LinkExecute"?? on what object is it being called?? What's the complete error message you're getting??

please see following details:

public Sub Main()

If App.PrevInstance Then        
   If Command$ <> vbNullString Then
       myform.HiddenText.Text = Command$
       myform.HiddenText.LinkTopic = "MyApplication|SendCmd"
       myform.HiddenText.LinkMode = vbLinkManual
       myform.HiddenText.LinkExecute myform.HiddenText.Text
       myform.HiddenText.LinkMode = vbLinkNone
    End If
    Unload myform
    Exit Sub

Else
    'perform some checks
    
End If

'pseudo code 
If checks are not valid 
    show message and exit
else
    if command$ has value
           myform.show
    else 
           myform.hide
    end if
end if

Exit sub
End Sub

Now in this case i get "Timeout while waiting for DDE response". Please reply.

I couldn't tell you. I haven't touched VB6 in over 8 years now. Sorry.
