Use of Alerter

[#1]

Hi All,

I want to use Alerter functionality of Qlikview.

My Requirement is like this,

I have one input box  that sets a variable vInput, if the value of vInput is greater than 20 then it has to  show an alert.

Regards,

Vivek

Hi Vivek,

In the InputBox properties > Constraints tab, select your variable, click on 'Custom' and type: IsNum($) and $ >= 0 and $ <= 20, then check the flag 'Error Message' and type your custom warning message.

Hope this helps.

Thank you for your response. It is working but can we do this using Tools->Alerts ??

Vivek,

Yes you can do that from the Alerts.

But you'll need to write a macro in your qvw (that you can find in the API Guide under Automation Examples > member PerformAlertAction, just write it as it is within a "sub...end sub"), then you'll set the trigger under Settings > Document Properties > Triggers > Variable Event Triggers > select your variable > OnInput > add the action RunMacro from type External and type your macro sub name in the field.

Though, I believe the first solution is simpler unless you have a reason to do it from macro.
