[wix-users] session.Message in custom action called from Dialog?

[Stephens, Rich]

No, because I wasn't using MessageBox.Show() to avoid that very scenario.  Phil Wilson's answer earlier in this thread was the correct one.  I actually now AM using MessageBox.Show() without any problems.  My MessageBox consistently opens in front of my installer.

I haven't tried out bootstrappers yet so I haven't bothered chiming in here, but I know that when I made a C# dll to use in a custom action I was doing stuff like this:
MessageBox.Show(String.Format("{0} does not exist", pathToXML));

And the message box would always pop up underneath the current WiX install dialog without getting focus. Could your issue be something as simple as your message box is hiding underneath your WiX dialog?

No, just a simple MSI project.

I had a dialog message in my installer (custom bootstrapper)... wouldn't work during an upgrade - the installation just "stuck" with no reason. Removed it and everything was golden thereafter.  I retooled the installer to not require it but, there might be calls for other "warnings to the user" to be implemented.  I hope not!


Are you using a bootstrapper? If so, might you be able to work one in that code, someplace?

So.... how am I to bring up a message box?  I've tried the spawndialog bit, but I seem to have trouble with coming BACK to my config dialog.  If it use the OK button on my error dialog  to "newDialog" back to my existing config dialog, the installer errors out, with an error code 2856.  What am I missing?  I just want the error dialog to pop up, and then to return to my config dialog when you click "OK" on it.

Session.Message results in a call to MsiProcessMessage, which doesn't work from a DoAction ControlEvent:

So, I am trying to validate my custom configuration dialog.

<Control Id="Next" Type="PushButton" X="236" Y="243" Width="56" Height="17"
Default="yes" Text="Next"> <Publish Event="DoAction"
Value="ValidateConfigSettings">1</Publish>
<Publish Event="NewDialog"
Value="VerifyReadyDlg">CONFIGSETTINGSOK=1</Publish>
</Control>

I am calling a c# custom action to do validation when the "Next" button is pushed.

Here's where I'm calling session.Message in my "ValidateConfigSettings"
custom action:

Record record = new Record();
record.FormatString = errMsg.ToString(); session.Message(InstallMessage.Error
|(InstallMessage)System.Windows.Forms.MessageBoxIcon.Error |
(InstallMessage)System.Windows.Forms.MessageBoxButtons.OK, record);

Everything is working exactly as desired.  The dialog doesn't continue if there's an error, etc, but... the message box doesn't appear.

Am I missing something?
