Ionic 4 menu not working navigating to root.

I noticed that all events of root/home page isn't working after I have navigated back in my ionic 4 app.

So if you using a back button or a button to navigate to the root page use following code.

Click event of back/home menu item

  onHomeClick() {

    this.navController.navigateRoot('/menu');

    this.menuController.close();

  }

Windows SDK not found. Ensure that you have installed Windows 8.1 SDK along with Visual Studio or install Windows 8.1 - ionic 4, WIndows 10 UWP

Windows 8.1 is pretty much outdated. I think most of portable windows devices using windows 10. So add following lines to config.xml of your cordova or ionic app.

    <platform name="windows">

        <preference name="windows-target-version" value="10.0" />

    </platform>

Cordova InAppBrowser EventListeners not working on iOS

Hi All


I'm using cordova-inappbrowser plugin for several purposes inside a cordova app. This plugin worked without a problem for months.

Then  I noticed its not firing loadstop event when the navigation completed. After 3-4 hours of hit and misses found the perfect solution.


Problem was my iOS platform wasn't latest.

So when you developing apps using cordova make sure your platform versions and plugins are up-to date with OS upgraded.

So all I had to do is



Removing iOS platform.

cordova platform rm ios

Adding iOS platform - Latest Version 

cordova platform add ios

Removing the plugin cordova-plugin-inappbrowser 

cordova plugin remove cordova-plugin-inappbrowser

Adding the plugin cordova-plugin-inappbrowser - Latest Version 

cordova plugin add cordova-plugin-inappbrowser

Using google places API with ASP.net Server Controls

 When you are trying to using Google places API on a ASP:TextBox it will give you following error.

InvalidValueError: not an instance of HTMLInputElement

 Reason for this is APS.net creating a client control as a TextArea not as an input field. Current version of Google Places API not supporting TextAreas for some reason.

But good news is you can still use ASP:TextBox with Google Places API. Only change you should make is set the TextMode of your ASP:TexBox as search.


TextMode = "Search"

 

Slowness of windows 10 and Google Chrome

Whats your favourite web browser? 

Yes, I know the answer its must be Google Chrome. What else as internet explorer is still too slow in response time and Firefox, Safari is still long way behind from google chrome.

But luxury is always comes with a cost. In my work computer I have 16GB of ram, state of state of the art  lintel i7 CPU and Solid State Drive as my primary storage.

Still my computer was too slow and and CPU usage was always about 100%. You can check cpu usage on your task manager.

So in my case I'm using google chrome installation for last year without clearing the cache or deleting temporary files.So google user data folder had around 5GB of space which slowing down the whole computer when I was using chrome.

 













So the solution.

1. First uninstall google chrome. Delete the old user data folder.

C:\Users\\AppData\Local\Google\Chrome\User Data

** You will lose all the bookmarks and any web browsing history. If you don't want to delete the history  just clear the google chrome cache. But its will not clean everything.

ASP.net publish to file system using old versions of release DLLs.

I still don't know the reason for this issue. I have a wild guess that my GIT configurations has something to do with this one.

Whats happened was when I'm publishing the project it was using old versions of DLLs.

Solution

All I had to do is build a release version before the next publish.

4. Copy the content to a folder in your C:\ drive.

Hi All

If using windows 10 and you are using a normal hard disc in your computer you may have experiencing slow starting-up, slow loading in apps and some lagging when using your applications.

Here are the tips for speed up your system.

1. Disable location service if you are not using.

Search >> Settings >> Location >> Switch Off Location Service

2. Disable un-wanted startup apps.

Right Click on Task Bar >> Task Manager >> ( Click  More Details if You Cant See Startup tab) >> Startup

3. Disable windows search - This will reduce the penalty of  indexing your files when you using the computer. ( Disabling windows search can slow down searching for files and folders )

Search >> Services >> Windows Search >> Disable Service

4. Disable Superfetch - This one is tricky. This function suppose to speed-up your system for NON-SSD based systems. But some times disc operation percentage can go up to 100% because of this service.

Do this if your disk operation percentage is 100%   without a valid reason. You can check disk operation percentage  from the task manager.

Here is how to disable Superfetch service.

Your connection is not secure - Firefox

There are few things you can do like check the date and time of the computer etc.  But my issue was I had running instance of fiddler web debugger. All I had to do is turn off fiddler.

As Microsoft Office 360 and 2016 is bit expensive for most users it is a good idea to go for open source alternatives.

Tips to save money when buying computer, laptop parts and cables

Please  note that this article using facts and data in Australia but I think this is true for most developed countries.



1.  Don't buy  

Again this is the best advice I can give for most common laptop, PC and Mac users. Sometime you actually really need the device and you just blindly buying it just because some retail shop giving you a 10% discount on the product. So please think at least 3 times before buy something.

Also if it's for a one time use just try to burrow it from a friend. But always return it on-time.

2. Do no buy it from major retail shops

This is a common mistake most people do when they need a cable or some other small part for a computer. These big retail giants has lots of expenses like rent, wages of workers and insurance etc.
Just try to buy the product on ebay, amzon or ali express and you will find the same product with a discount more than 30%-50%.


3.Try facebook market place or gumtree

Some times offices  and some people tend to put these items on online market places for free or for a very small amount of money. Even these things are used, especially cables they can last longer. .


4.Cables and Accesries for Apple products are expensive 

Just consider this as when you choosing an apple product, They are very good products and comes with an additional cost.

5.Do not throw cables away

You never know when you need things and please keep your old cables and other commuter parts for at-least four to five years.








 

iTunes connect UI freezes.

When you publishing apps for apple store using itunes connect screens are freezing more often. Main reason behind for this is poor internet connection. Make sure you have a good internet connection when you publishing apps to apple store.

I'm always using my mobile's hotspot if the wi-fi or LAN is super slow.
