Giving a Form a Unique ID

Hi Nothern_Lights,

Is this an MDI application or an SDI application? The key really to either is to determine exactly what happens, you have the relevant transcode in each form's caption so this is what you could use. Personally I would store this in the form's .Tag property but caption is fine.

It depends on how you activate the main form from each transaction, you may be able to set a property in the main form from the last activated transaction form for example.

Hey Tim

What is the difference between MDI and SDI application?

In the frmSaleToClient properties I have in the caption "Sale To Client"

And I use code to change the form caption to the transaction ID but when I read the form caption I get “Sale To Client” but on the screen is has the Transaction ID

I tried storing the Transaction ID in the Form Tag but i still got the same problem for so weird reason

Thanks

Nothern_Lights,

Firstly, MDI - multiple document interface, where you have a parent form and child forms are contained and constrained within it. SDI - Single Document Interface, here you can still have multiple forms but they are effectively only constrained by the desktop. Word and excel are good examples of an MDI interface, though these days you can make them work in a pseudo-SDI way as well.

The reason you still get "Sale To Client" I would expect is that you are not referencing the form you think you are. Because you are creating new instances of the same base form, if you refer to "frmSaleToClient.Caption" it will actually open a hidden instance of the base form and that is the one you are probably getting the information from. You could probably use ActiveForm.Caption / ActiveForm.Tag to determine which form you are currently referring to. This will work excellently in an MDI interface but perhaps not so well in SDI.

I think that by declaring the form with the new keyword the form load event fires first before the current sub executes.


Dim frm As New frmSaleToClient

Change to:

Dim frm As frmSaleToClient
set frm = New frmSaleToClient

I can only get ActiveForm.Caption / ActiveForm.Tag to work using MDI form

I would prefer to not to use MDI use SDI instead

Thanks
