I want to read the name of the last loaded form out or a .ini-file. Then I want to load the form.

For example:
the last form was 'frmTest'. I read the name into gsForm.
Now I want to load the form 'frmText'.

I can't use the code
 For x = 0 to Forms.Count-1
    ...
 Next x

because it only works with the forms already loaded.
What's to do?

Before I can answer your question, I would like to have a bit more information.

1 - Do you refer to your form frmTest by its design time name?
    for example
    frmTest.Show vbModal
2 - Do you instantiate your form through object variables?
    for example
    Dim myForm As frmTest
    Set myForm = New frmTest
    myForm.Show vbModal
3 - Do you wish to re-display a form with its old contents or do you intend to create a new instance of the form?

Hi caraf_g,

frmTest was an example. the formname could be any form in my application the user can work with. For better understanding:
dim gsForm as string
gsForm = "frmTest"
gsForm.Show <- something like this

Sorry, not possible. The only thing that you can do is have an switch statement and test on the name and make an instance of this form.

Having only used VB5 myself I can't guarantee that the following will work. I hope it is possible in VB4 to Dim variables As Object, and that you can use the Set keyword in VB4.

If you can, this might work for you:

Dim gobjForm As Object
Dim gsForm As String

Select Case gsForm
Case "frmTest"
    Set gobjForm = New frmTest
Case "<other form>"
    Set gobjForm =.... and so on
.
End Select

All the best, and good luck
