Windows 10 Disable Offline files option is disabled

On Windows 10, there is a feature to make mounted network drive contents available when the network is not connected.  Its called Offline Files. This feature is managed by Microsoft Sync Center.  This works by syncing the contents periodically when the network is connected.

Enabling the Offline Files feature

When the network is connected, Right click on the mapped network drive. Select "Always Available". This will activate the Offline Files feature and start the Sync center.
Otherwise, go to Control Panel and select Sync Center.

Disabling the Offline Files feature

Go to the Sync Center. Select Manage Offline Files. Then select Disable Offline Files.

Above functionalities are straight forward. This post is not mainly about that.

Disable Offline Files option itself is Disabled

Recently I tried enabling this feature and found it not useful due to network drive permission issues.

I wanted to disable it as I was not able to access files on mapped drive. It was throwing errors like "Permission Denied" for every file and directory.

But the option to disable it was disabled. I explored a lot on Google and found some methods to disable it on Registry. But even that dint help me. When I restarted my laptop, the registry setting was again rolled back.
My company group policy had some settings because of which I was not able to disable the Offline Files feature.


Go to Search option and enter "group policy". It will show an option "Edit Group Policy". Select it.

Then on the left hand side, you will find "Computer Configuration" and "User Configuration".

Expand "Computer Configuration". Select "Administrative Settings -> All Settings".

You will see a lot of settings on the right side. In this you have to sort "path" column by clicking on it.

Look for path ending with "Offline Files".

You will see many items for Offline Files. Select the setting "Allow or Disallow Offline Files Feature".

If you have faced above problem, there are high chances that the existing value for this setting is either "Disabled" or "Enabled".
Right click on it and select "Modify". Then select "Not Configured".
Close the window and restart the PC.

Now the option to Disable the offline files feature will get enabled after the reboot.

After disabling the offline files, again reboot the system to see the feature being disabled.

Display Port to HDMI Conversion

Recently I faced a problem. I bought a 3D LED TV(LG42LA6200) which supports HDMI and many other features. I have a office laptop HP ProBook 6460b which does not support Intel WiDi application. Intel WiDi is a technology through which we can connect the display using WiFi. Without looking at laptops specifications properly, I thought HDMI is supported in my laptop. The Display Port looks similar to HDMI port except a small notch in the corner of the port. I thought it as HDMI port and bought a HDMI cable. The cable arrived home and i was shocked to see that I cannot connect HDMI to my Lap top  :(. Now what should i do?... Then I explored a bit on Google about this Display Port Vs HDMI port and found that there is a Adapter which converts the Display Port to HDMI female port. I was happy to see that. Otherwise my HDMI cable would have been a waste.

 Display Port to HDMI Female Adapter

Connecting the HDMI cable to Adapter

Identify the Display Port in the Laptop

Connect the Adapter to the Laptop

The Moment you connect the Cable from TV to Laptop and both are powered on, TV will automatically detect the HDMI Input. On Laptop you can extend or duplicate the displays just like connecting to projector. On Win 7, Go to Control Panel-> Display -> Connect to Projector Option and select the required option. I usually select the extend option. Play the movie on TV and do browsing on my laptop screen.

Visual Basics for Applications

If you have studied computer science in your academics then you will be aware of Visual Basic. Visual Basic is a programming language used in Microsoft Visual Studio for developing software applications. There are many versions of Visual Basic. We normally call it as VB script. Its is used in both stand alone and web based applications. Stand alone application is a software which is stored and executed in a local system. Web Based application is a software which is stored in remote servers and runs on a internet browser. VB is equally wast as other computer languages like C, C++ and a very interesting, easy language to learn.

A typical VB script looks like:

Main Form code
Button1.Name = "Click Here"
* here we specify all the design properties. How a window should look like, how many command
buttons it should have, what are all the lables it should have , etc*
End of main form code

Private Sub FuncName( ByVal Name as String )
Label1.Caption = "Your name"
Label2.Caption = Name
End Sub

Sub "FuncName" is the Sub routine which is similar to a typical C, C++ void function. Main difference is it will not Return Values. No need to specify parenthesis while calling a sub.

VB also has Functions which can return the values.

Private Function sum(ByVal a as integer, ByVal b as integer)
End Function

In above function the value is returned by assigning the return value the name of function. This is similar ti user defined functions in C, C++.

Above Sub is called as below:

Private Sub Button1_Click()
FuncName "John"
End Sub

Above Function is called as below:

Private Sub Button2_Click()   - This will get called when the button is clicked.
Dim total as Integer
msgbox total
End Sub

Above we have seen the code written for a click event. Normally it is left mouse click. Similarly we can write code for every event that includes keyboard events, mouse events, etc.

Now lets know About VBA

VBA is a version of VB script used in MS excel for writing Macros.

What is a Macro?

Generally in Micro Processors Macro is a piece of code which is written to reuse multiple times in a module. Procedures are also for the same purpose, but there is a huge difference between procedures, functions and macros. Procedures, Macros, Functions these are mainly used for modularity, re usability and memory efficiency purposes. Macros are written to perform a task. Whenever that task needs to be performed, we can call it required number of times. Whenever a macro is called, the call is replaced by the code written for that macro. This replacement happens during level 1 parsing of code. Where as whenever a  Procedure or a Function is called, execution jumps to the place where the procedure or function is written and again jumps back when the execution of procedure or function is complete. So it is cumbersome for the processor in second case. Benefit of using procedure or function is it saves lot of memory while degrading the execution speed. Macros will eat up lots of memory while execution speed will be good as the execution is contiguous.

What is a VBA Macro ?

VBA means Visual Basic for Applications. This terminology is used when the VB script is used in MS excel. In MS Excel we store the data in row's and column's. We call it as spreadsheets. In some cases we need to perform some calculations on the data present in the sheet and in other cases we need to extract only required portion of data from sheets containing large amount of data. Normally we perform calculations by storing formulas in formula bar for specific Cells and we extract data by copy paste operations. Doing these operation multiple times will consume lot of time and it leads to human errors most of the times. Hence we write a piece of code that does all the actions multiple times accurately. That piece of code is called VBA Macro in MS Excel.

So the meaning of Macro is similar in all subjects and it is used in different ways.

How does a typical VBA Macro look like ?

Sub Macro1()
With Activesheet
End With
End Sub

In above macro "Macro1" is the name of the Macro.
Activesheet will point to the tab which is currently open.
Everything in Excel is Cells. It is a part of sheet defined by row and column. 5 is row and 1 is column.
"With" block is used to do many operations for a single context.
All the loops of programming such as for,while,do while and if conditions are possible in VBA.

Same VB script is used in Excel to write Macros. But the difference in VBA is there are many excel specific functions like Activesheet, Worksheets etc. These excel specific functions are invoked inside VB script.

This is a overview of VBA. You will find many sources for detail information about writing macros in VBA. If you have any errors or questions regarding VBA, just post a comment and I will try solving it for you...:)
