Now on to dialogs.
I have some questions on building a custom dialog. I want to build a dialog that will
prompt the installer for a user name and password (that will eventually get assigned
to the service so the service will run under this account). Currently I have:
<!-- Adds the dialog used to specify the virtual directory name -->
<dialogs>
<dialog name="UserCredentialDlg" hcenter="50" vcenter="50"
width="360" height="150" attr="39"
title="[ProductName] [Manufacturer] [ProductVersion]"
firstcontrol="UserName"
defaultcontrol="UserName" cancelcontrol="Cancel" />
</dialogs>
<!-- Adds the controls associated with the dialog -->
<controls>
<control dialog="UserCredentialDlg" name="UserLabel" type="Text"
x="8" y="8" width="128" height="23" attr="3"
text="User:"
nextcontrol="UserName" />
<control dialog="UserCredentialDlg" name="PasswordLabel" type="Text"
x="8" y="40" width="128" height="23" attr="3"
text="User:"
nextcontrol="Password" />
<control dialog="UserCredentialDlg" name="PasswordConfirmationLabel"
type="Text"
x="8" y="720" width="128" height="23" attr="3"
text="User:"
nextcontrol="PasswordConfirmation" />
<control dialog="UserCredentialDlg" name="UserName" type="Edit"
x="136" y="8" width="216" height="20" attr="7"
property="USERNAME"
text="[USERNAME]"
nextcontrol="Password" />
<control dialog="WebFolderDlg" name="Password" type="Edit"
x="136" y="40" width="216" height="20" attr="7"
property="PASSWORD"
text="[PASSWORD]"
nextcontrol="PasswordConfirmation" />
<control dialog="WebFolderDlg" name="PasswordConfirmation" type="Edit"
x="136" y="72" width="48" height="18" attr="7"
property="PASSWORD"
text="[PASSWORD]"
nextcontrol="OK" />
<control dialog="UserCredentialDlg" name="OK" type="PushButton"
x="16" y="112" width="56" height="17" attr="3"
text="OK" nextcontrol="Cancel" />
<control dialog="UserCredentialDlg" name="Cancel" type="PushButton"
x="272" y="112" width="56" height="17" attr="3"
text="Cancel" nextcontrol="BannerBitmap" />
</controls>
As I understand it this will assign the value entered int the control to a property.
Question 1, If the installer clicks on OK how does the dialog quit? It seems to be a
requirement to have a nexcontrol attribute. How does the dialog know to close out and
use the values entered if the user clicks OK? What if CANCEL is clicked on? How does
the dialog know that the values should not be used? In this case since these are
required for our installation if the installer clicks on CANCEL I would like to abort
the whole installation. Question 2, I would also like to do some validation of the
input. If the user entered an incorrect user name and/or password I would like to run
the dialog again maybe indicating some error or warning. If the password and the
password confirmation don't match I would also like to issue a warning and give the
installer a chance to try again. I am not sure how to do this given the examples.
Maybe I need a tutorial or a pointer to some docs.
Finally, what causes this dialog to appear? When does it appear in the sequence? Like
I said I would like to have the user and password properties set so that in a custom
action I can retreive them and set the service properties so that the service will run
under this account. So I want to make sure that these properties are set prior to the
custom action and I need to know when to execute the custom action so that it will be
executed after the services have been installed. Any pointers?
Thank you.
Kevin
