Thanks to your help, I'm almost there.
I've set up my custom dialog with the Next button defined as;
<Control Id="Next1" Type="PushButton" (snip) Text="&Next1" >
<Publish Event="DoAction" Value="MG_CA_VerifyBothDir"></Publish>
</Control>
Then, I have my dialog publishing either go to the next dialog in the UI or the
"DirNotExist" dialog that I created based on properties.
<Publish Dialog="MG_Cat_DataExportDir" Control="Next1" Value="DirNotExist"
Order="2" Event="NewDialog"> (DATAEXPORTDIR_CHECK OR
DATALOADERDIR_CHECK)</Publish>
<Publish Dialog="MG_Cat_DataExportDir" Control="Next1"
Value="MG_CoreServerDlg" Order="1" Event="NewDialog">NOT (DATAEXPORTDIR_CHECK
OR DATALOADERDIR_CHECK)</Publish>
My problem is that the error dialog is never displayed on the _first_ time
through. Here's the log;
Action 11:13:06: MG_Cat_DataExportDir. Dialog created
(snip)
MSI (c) (7C:84) [11:13:09:743]: PROPERTY CHANGE: Adding DATAEXPORTDIR property.
Its value is 'c:\abc'.
MSI (c) (7C:84) [11:13:14:618]: PROPERTY CHANGE: Adding DATALOADERDIR property.
Its value is 'c:\123'.
MSI (c) (7C:84) [11:13:14:743]: Doing action: MG_CA_VerifyBothDir
Action 11:13:14: MG_CA_VerifyBothDir.
Action start 11:13:14: MG_CA_VerifyBothDir.
MSI (c) (7C:5C) [11:13:14:758]: Invoking remote custom action. DLL:
C:\DOCUME~1\ADMINI~1\LOCALS~1\Temp\MSI11D.tmp, Entrypoint: VerifyBothDir
MSI (c) (7C!50) [11:13:14:915]: PROPERTY CHANGE: Adding DATALOADERDIR_CHECK
property. Its value is 'Error - Data Loader directory does not exist: c:\123.'.
MSI (c) (7C!50) [11:13:14:915]: PROPERTY CHANGE: Adding DATAEXPORTDIR_CHECK
property. Its value is 'Error - Data Export directory does not exist: c:\abc.'.
Action ended 11:13:15: MG_CA_VerifyBothDir. Return value 1.
Action 11:13:15: MG_CoreServerDlg. Dialog created
So, you can see that the next dialog, "MG_CoreServerDlg", was displayed even
though it seems the conditions previously defined would have prevented this.
I tried to put the custom action prior to the SpawnDialog like this;
<Control Id="Next1" Type="PushButton" (snip) Text="&Next1" >
<Publish Event="DoAction" Value="MG_CA_VerifyBothDir" Order="2">1</Publish>
<Publish Event="SpawnDialog" Value="DirNotExist"
Order="1">DATAEXPORTDIR_CHECK OR DATALOADERDIR_CHECK</Publish>
</Control>
But this didn't seem to work either.
My problem is that I have a "lag" where the property is being set, but the Next
button doesn't recognize it until the dialog is reinitiated.
I'd appreciate help on getting this working properly.
Thanks,
Dale
