Hi Alex,

I'm getting this error:
"method 'Item' of object 'IMessages' failed"

when I called:

        Dim lngSelectedMsg as Long
        lngSelectedMsg = myGrid.Row
        Set oMsg = oMsgs.Item(lngSelectedMsg)
        txtFrom.Text = oMsg.FromAddr
        txtTo.Text = oMsg.ToAddr
        txtSubj.Text = oMsg.Subject
        txtBody.Text = oMsg.BodyText

I'm trying to display the selected message (from a flexgrid) to the interface. Do you know what causes the problem?

Most likely, lngSelectedMsg index is out of range. For instance, oMsgs.Item(0) will cause an error.

To be valid, the index value passed to Messages.Item method must be in the range 1 to Messages.Count. In other words, Messages collection index is one-based, while myGrid.Row index is probably zero-based.

You may try this:

Code:

Set oMsg = oMsgs.Item(lngSelectedMsg + 1)

Alex

Hi Alex,

Thanks for your reply. When I run through debug mode, lngSelectedMsg is actually a non-zero. When I click on the second row, the value of lngSelectedMsg is 2, but yet it seems to always fail to pass the line:

Set oMsg = oMsgs.Item(lngSelectedMsg)

Where can I look at the method 'Item' that contains 'IMessages'? Thanks for your help.

Are you sure lngSelectedMsg=2 is valid for the given collection? lngSelectedMsg must be less or equal to oMsgs.Count. If oMsgs contains one or zero messages, oMsgs.Item(2) will fail.

IMessages is an internal name of Messages type. Thus, Item member reference can be found in MailBee documentation at "Reference/Messages Collection/Item Property" topic.

Regards,
Alex

You're right. In my code, lngSelectedMsg was initially a Long type, but after many re-uses it was converted to a string type and thus it was giving various errors. Now it works, thanks a lot!
