Backup solutions for normal windows pc/laptop users. ( Not for geeks )

I have done few data recovery jobs for normal personal computer users who couldn't start their computers because of several reasons. Even though it's not a big deal to get your data back when your computer is in good shape and your windows operating system  isn't working.

But it's very hard for some one who doesn't  have the skill of doing it. Also if you go to a technician they will charge you at least  hundred dollars to do these things.  Other than that you'll have to expose your personal data to a third party and they can do some damage if they are not very professional people.

So my advise is its always good to prevent these scenarios before something happened to your windows operating system. If you follow these steps you will be confident enough to format your hard disk and  install a fresh copy of windows operating system.

1. Always make at-least two partitions in your hard disk and use one only for operating system and other one for data.

2. Do not save any sensitive data in your OS drive. If you concern about privacy and security of data use window's default  Bitlocker encryption tool. ( You cant use bitlocker in windows home editions )

3. Use a personal file sharing application like dropbox or google drive and configure it to sync your data automatically.

4. Use external hard disk to backup your data time to time.

5. Make sure you always have your data in at lest two physical locations in case of a disaster. ( Cloud and Your PC will be ok for a basic backup plan )

6. If you want to use an antivirus software please buy a commercial antivirus. Never use a pirate copy of  an antivirus software. ( Simply do not use any pirate copies as there are many opensource alternatives around )

7. Do not use an older versions of antivirus software. This will cause compatibility issues and  will  reduce the speed of your computer.
     

How to load image on webview from ms-appdata:///local

I recently updated my  Visual Studio 2015  apache cordova project to visual studio 2017. I had few problems with working with angular js otherwise everything worked in windows 10 environment.

But what I noticed was images from ms-appdata:///local folder couldn't load  to img tags. I tried many ways like row html, dynamic tag creation and add url as a base64 data url.

In base64 solution it worked. But I want to get the file itself  as my app was supporting iOS and Android as well.

So after trying hundred things solutions was simple.  You have to set img-src  option to All ( *  ) Content-Security-Policy meta tag of the html file.

Please check following screen shot. You need to add the part with the read border to load image resources from any location.

Reference URL  if you need to see more options.

Invalid command line switch for tsc.exe. Visual Studio 2015 - 2017

After I installed visual studio 2017 while I had visual studio 2015 in good working condition my visual studio 2015 cordova Javascript project gave me this error.


Invalid command line switch for tsc.exe


Possible cause for this one is with visual studio 2017, you'll be getting new typescript libraries. So visual studio 2015 is confusing when selecting the highest typescript version automatically.

If your project is javascript based cordova project fix is easy.

1. Open project file in notepad or any editor you using.
2. Edit following section.

* You cant use this fix for typescript based cordova projects.
* If you still see some errors your visual studio 2015 may needs a repair.  Please follow the link bellow regarding repairing vs 2015.
