## Using PostgreSQL Stored Procedure with Parameter in Xamarin Forms

I posted a blog about reading data from PostgreSQL in Xamarin forms actually almost ever thing same but now we need to add parameter and declare which type command we will use.

Let’s start coding with connecting database.

## Network Diagram

- Find the critical path
- Calculate Total Flot and FF
- What is length of the project.

Total Flot(Slack) : This mean is how many days you can delay this work

To calculate total flot you must consider all activity one by one the formula is

Late Finish – Early Finish

Predecessor: The work that before must be done

## Physics 2 Midterm and Final Formula Sheet

I was looking for a formula sheet before my physics exam but there was not good one because I want to see all formulas in two pages but there was huge pdf like 30 pages. I decided to create my own formula sheet. I think it is perfect now and I would like to share it with you.

## Using ZXing (QR Code Scanner) in Xamarin Forms

For using Zxing in Xamarin Forms we have to first add nuget to both project which are Droid and iOS.

After adding nuget to our project in Droid project open MainActivity.cs and add below code to class

public override void OnRequestPermissionsResult(int requestCode, string[] permissions, Permission[] grantResults) { ZXing.Net.Mobile.Android.PermissionsHandler.OnRequestPermissionsResult(requestCode, permissions, grantResults); }
