PowerApps - Back to Basics - With function

By Vinod Thachin -
With function in PowerApps allow to simplify the complex formulas in to smaller functions. This will enable us to calculate the value or perform the operations as per the requirement. We can pass the Record or reference field names or named vales. Named values will work as variables with in the scope.

Syntax for With,

With 
(
        <<Record>>,
        <<Formula>>
)

Real Time Usage - 

One of project, i need to filter the list based on Created Date and Created By user.

Created Date = Today()
Created By = User Logged in to the System.

I have used following formula to achieve the functionality,

With(
   {
      myList:
      Sort(
         <<Source List>>,
         Created,
         Descending
      )
   },
   LookUp(
      myList,
      Author.Email = User().Email &&
      IsToday(Created)
   )
)

Here i am using the myList as a named value and filtering the Records based on User and Created Date. I am seeing the value to a Collation and binding this to Gallery to show the records on the User opening the app.

Linksys Wireless Connection Failure

By -
I configured the Linksys wireless router [WRT54G] couple of years before and it just worked great. I myself configured the password and everything worked great at my home. Anyone comes in home takes my password and it just worked great most of the time. all these were with windows server 2003 and Dell machaines. When I bought a new Hp DV9000 (XP) I had an issue connecting to the home wireless. I started browsing and found this solution: Issue : Couldn't connect to the selected connection. 1. Installed an update http://www.microsoft.com/downloads/thankyou.aspx?familyId=17d997d2-5034-4bbb-b74d-ad8430a1f7c8&displayLang=en Issue after the update : Acquiring Network address status and stayed there. Did the following after that: 1. Browsed http://192.168.1.1/ 2. used the user-id / password of the connection (default userid is empty & pwd is admin) 3. Navigated to wireless (Basic wireless settings), click Reset security and name your userid for SSID 4. Clicked save settings 5. cli

Power Apps toPower Automate Error - The input body for trigger 'manual' of type 'Request' did not match its schema definition , the input String does not validate against the date

By Vinod Thachin -
While working with power Apps to Power automate, passing the Date time values as Text(DateTimeValue) throws error as below. The input body for trigger 'manual' of type 'Request' did not match its schema definition. Error details: 'String '' does not validate against format 'date'.'. After checking the Microsoft documentation and few blogs i found out the date values should be passed as a formatted date time. TO pass the date time  we need to use following functions. Text(<<DateTimePicker>>.SelectedDate,"[$-en-US]yyyy-mm-dd") Even after passing the value i am still seeing the same issue and finally found out the default value ids sending as empty and formulae failing for empty values. So we need to make sure the Date Value should not go blank to the formulae and the value should be formatted using the formulae as above. Hope this helps.
