[AccessD] In a legacy system how control a Vba MsgBox

 Thanks Drew.

 I have some API experience, but no where close to being
 an expert in it.

 Luckily I have the ability to get to the original Vba code.

 Yes please, I would like to see your API code.

 Thanks.

 Sincerely,
 Ed Zuris.

Hmmmm, this is a little trickier then I think some of the replies have
posted.  You said you are automating this, which means that you are
using your own code to open a form.  And that form goes and opens a
msgbox at some point.  The problem is, that when you open a form, and
cause the msgbox to be opened, that messagebox is going to be modal, so
that the calling code will freeze.  Let's say that the msgbox appears
when the form initially opens, what you will find, is that your code is
going to never get to the next line, until the msgbox is responded too.
If the msgbox appears when a textbox value is set, then your code will
freeze at the point where you set the text value, etc.  

There are three solutions that I know of:

1. Modify the original code, so that it presents a form, instead of a
msgbox, so that it can be opened and responded to non-modally.

2. Modify the original code, so that the it accepts a value from a
msgbox that your own code prompts with.

3. (This one is a bit more involved and trickier, and should only be
used if you can't modify the original code (like it's in an mde)).  You
need to have a separate thread watch for the msgbox and react to it.
This can be done with a multithreaded app (which you can't do in VBA,
you can do this in VB 6 or .NET), or create a separate app that your
program kicks off, which monitors for the msgbox.  Either way, to do
this, can 'detect' the msgbox as being a child window of the Access
window, it'll have a specific class/title.  I have some code lying
around that may be useful, holler if you want it.  If you don't have  a
lot of experience with window API's, it might be a little confusing at
first....

 Dear AccessD Forum
 
 I am doing a little automation work within a legacy  environment.
 
 From inside some VBA code, a form is opened, given some
 data, where buttons and controls are clicked.
 
 The opened form, ft001CreateTasks, has a MsgBox asking
 a Yes/No question.
 
 What kind of handle do I use to click the YES button
 on the message box modal form ?
 
 Or are there some other way of tackling this issue ?
 
 Thanks.
 
 Sincerely,
 Ed Zuris.
 

    ====================================================
                 Example Vba Code snippet
    ====================================================
 
    strVar = ""
    DoCmd.OpenForm "ft001CreateTasks", , , strVar
 
    strVar = "Rake Yard"
 
    Forms("ft001CreateTasks").cboTaskType.Value = strVar
 
    Call Forms("ft001CreateTasks").cboTaskType_Click
 
    . . . . now a message box open on the form . . . . .
