Hi all,
As a part of my installation, I give the user the option to create a new
website. For this, I have a control in which the user can specify the new
website port.
Using a "MaskedEdit" type control, I was able to limit this field to 5 numeric
characters, but found out that this has a couple of disadvantages:
First, I can't detect if this field is empty (it gets a value of ' '
instead of not exist), and I really need to do that in order to show a proper
warning message.
Second, I can't seem to be able to test that the port number is < 65536.
So, as a result, I made the control an "Edit" type one, with Text="{5}",
instead of "MaskedEdit", but now I have 2 problems:
First, if I set this control to Integer="yes", if the user enters non-numeric
characters he gets an ugly "internal error" message from the MSI upon pressing
"next", which I can't seem to avoid or change. If I change to Integer="no" I
completely lose control over it (it is read as a string and I can't ask
mathematical questions on it).
Second, I still can't seem to be able to validate that port number < 65536.
This is how the control is defined:
<Control Id="NewPortEdit" Type="Edit" X="225" Y="106" Width="30" Height="15"
Hidden="yes" Integer="yes" Property="NEW_WEBSITE_PORT" \>
And this is an action attached to pressing the "next" button, with a condition
that is never true, somehow:
<Publish Event="SpawnDialog" Value="PortErrDlg">
NEW_WEBSITE_PORT>65535</Publish>
What is the best way to achieve what I need (being able to prevent the field
from being empty, making sure it is numeric, and that it is not greater than
65535) ?
