The Windows Ribbon framework is a rich command presentation system that provides a modern alternative to the layered menus, toolbars, and task panes of traditional Windows applications. Similar in functionality and appearance to the Microsoft Office 2007 Fluent user interface, the Ribbon framework is composed of a ribbon command bar that exposes the major features of an application through a series of tabs at the top of an application window, and a context menu system.

In This Section

There are 2 ways to do this

1. Modify the project UAC settings

2. Go to debug and then run your program .exe file as administraotr

We will discuss both the methods let's start with the first method

Well for the first method you need to replace only 1 word .

See this video for the first method :

Here is the 1st method

"You need to make your application UAC compliant so that it will ask user to grant your application Administrator access".

to make your application UAC compliant,

Double Click My Project in Solution Explorer and Click UAC Settings button as shown in image.

Then Modify app.manifest file as shown below. Make it 'requireAdministrator' instead of 'asInvoker' and save.

Now let's discuss the second one

For that go to debug folder and then find your application .exe file and then right click on it and select properties option

Now when the dialog box appears.

Then go to compatiblity tab and cehck the option always run this prgram as administrator.

This does the same job.

Thanks !

Back to the Future – VB6 Variant Redux?

In VB6, we could use a variable without declaring it as …

myVar1 = "whatever"
myVar2 = 666

The variables were compiled as Variant types, which could hold anything.

This was carried over into .NET as Object types. If Option Explicit is Off, then you can write the same code and the variables became Object types. Again, they could hold anything. But the default changed in .NET (Option Explicit is On by default) and we were strongly encouraged to declare everything. Not only did it help the compiler catch errors so the application didn't crash at runtime, but the code ran faster because the variables were "early bound" instead of "late bound". With late binding, the compiler has to add code to figure out what a variable is before using it and that slows everything down. VB 6 was slower for the same reason.

The Option Strict statement

By default, the Visual Basic .NET or Visual Basic compiler does not enforce strict data typing. To change this default behavior, see the Change the Default Project Values section.

Option Strict restricts implicit data type conversions to only widening conversions. Widening conversions explicitly do not permit any data type conversions in which data loss may occur and any conversion between numeric types and strings. For more information about widening conversions, see the Widening Conversions section.

When you use the Option Strict statement, the statement must appear before any other code. In Visual Basic .NET, you can typically convert any data type to any other data type implicitly. Data loss can occur when the value of one data type is converted to a data type with less precision or with a smaller capacity. However, you receive a run-time error message if data will be lost in such a conversion. Option Strict notifies you of these types of conversions at compile time so that you can avoid them.

For Option Compare please visit :  http://msdn.microsoft.com/en-us/library/8t3khw5f(v=vs.80).aspx

The word ByVal is short for "By Value". What it means is that you are passing a copy of a variable to your Subroutine. You can make changes to the copy and the original will not be altered.

ByRef is the alternative. This is short for By Reference. This means that you are not handing over a copy of the original variable but pointing to the original variable. Let's see a coding example.

Add a new button the form you created in the previous section. Double click the button and add the following code:

Dim Number1 As Integer

Number1 = 10
Call IncrementVariable(Number1)

MsgBox(Number1)

You'll get a wiggly line under IncrementVariable(Number1). To get rid of it, add the following Subroutine to your code:

Private Sub IncrementVariable(ByVal Number1 As Integer)
Number1 = Number1 + 1
End Sub

When you're done, run the programme and click your new button. What answer was displayed in the message box?

It should have been 10. But hold on. Didn't we increment the variable Number1 with this line?

Number1 = Number1 + 1

So Number1 started out having a value of 10. After our Sub got called, we added 1 to Number1. So we should have 11 in the message box, right?

The reason Number1 didn't get incremented was because we specified ByVal in the Sub:

ByVal Number1 As Integer

This means that only a copy of the original variable got passed over. When we incremented the variable, only the copy got 1 added to it. The original stayed the same – 10.

Change the parameter to the this:

ByRef Number1 As Integer

Run your programme again. Click the button and see what happens.

This time, you should see 11 displayed in the message box. The variable has now been incremented!

It was incremented because we used ByRef. We're referencing the original variable. So when we add 1 to it, the original will change.

The default is ByVal – which means a copy of the original variable. If you need to refer to the original variable, use ByRef.

Note: This tutorial can also apply for other languages because the basic programming fundamentals are the same .

And you can also take a look at this page in which this concept is explained clearly – http://www.homeandlearn.co.uk/net/nets9p1.html

So first start from the easiest concept.

We all know that in our form class there are many subroutines like

a subroutinethat appears when we double click an command button in design view.

That is a subroutine because of the keyword sub which means it is a subroutines.

Subroutines and Functions are called procedures .

Remember procedures are jsut self contained blocks of code and are of 2 types

1. Subroutines

2. Functions

Now let's see the procedure(subroutine) that appears in code view when you double click an button in desig view.

In this screenshot errorcheck is a subroutine.

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

End Sub

This is a self contained block of code which means it contains code inside itself (in this case it dosnt because we havnt enter anything inside it)

So the first time you look at it you can say it is a self contained block of code it contains code inside

sub statements and end sub statement

Now we also see that sub keyword in the first line which obvyously means it is a subroutine .

So now comes the time when you should know the defination of subroutine .

A subroutine is a procedure which does some thing(someprogramming task) but it dosnt return any value.

example : the command1_click sub

we can call subroutines by just entering their name like take the example of this sub.

public sub dosomething()

endsub

Now to call it simple type in

dosomething()

And Now let's discuss about functions .

Functions are same as subroutines . They also perfom some task but they have a special property that they return values inside the calling variable .

verify postal code is a function as it returns an string value to a variable that calls it

confusing?? Dont worry

i will show you what i mean

when you have written this function and you know that a function is a procedure that returns a value then you have to store this value somewhere when you call it

so in this case it returns a string value so we will declare a new variable as string

dim test as new string

now we will calll the function

test=verifypostalcoe(arguments )

The function will return a value after calculations and store it inside the test variable.

Things that functions and sub's have common in them

1. both of them are self contained blocks(procedures)

2. Both of them do some task

Have any doubt dont hesitate to ask me in the idealpogrammer forums or via comment.

Here are the videos which are related to this topic -

Thanks!!

Before .NET Framework 2.0 if you wanted to compress files you had to use a 3rd party library capable of doing that. In the new version there is a new namespace: System.IO.Compression that contains the GZipStream class. The GZipStream class has methods allowing us to both compress and decompress a file into a zip archive.

The disadvantage of using the GZipStream class over a 3rd party product is that it has limited capabilities. One of the limitations is that you cannot give a name to the file that you place in the archive. When GZipStream compresses the file into a ZIP archive, it takes the sequence of bytes from that file and uses compression algorithms that create a smaller sequence of bytes. The new sequence of bytes is put into the new ZIP file. When you open the ZIP file you will open the archived file itself; most popular ZIP extractors (WinZip, WinRar, etc.) will show you the content of the ZIP as a file that has the same as the archive itself:

This is because the GZipStream class does not specify a file name in the headers, as metadata, since in the specifications of the GZIP file format, declaring a name is optional. This may not bother you if you are using this class to compress files used by your application (such as archiving old documents) and when the usage of the GZipStream class comes just a single piece of the puzzle in a larger application.
On the other hand, if you're looking to build an application that has the solely purpose of zipping and unzipping files, you will encounter some of GZipStream's limitations. If you decide to use a 3rd party class library in that case, or if you prefer to stick to GZipStream, is your choice. There is a workaround for giving file names to the ZIPs content by modifying the headers yourself. For information on how to change the headers, please see the MSDN Magazine article entitled NamedGZipStream, Covariance and Contravariance.

Zipping (sample application)

Let's start by creating a new Windows application project into Visual Studio 2005. Add to the form a TextBox and two Buttons. The TextBox is entitled txtPath and it will hold the path to the file to compress. The Buttons are entitled btnBrowse and btnCompress. The first one will show an OpenFileDialog for picking a file to compress, and the second one – btnCompress – will show a SaveFileDialog followed by the actual compressing and saving process. Speaking of these two dialogs, make sure you add them to our application and name them openFile and saveFile.

The two important namespaces we'll use need to be added at the top of the class file so we don't have to write really long lines:

Now double click btnBrowse and its Click event will be created. Inside it use the following code that displays the OpenFileDialog and allows the user to pick a file:

Now that we got the path, it's time to take that file and compress it. This happens when the user clicks on the btnCompress button, thus double-click it to get to its Click event and inside use the following code:

Hopefully the comments will explain the code to you entirely; as you can see we don't have any room for error in this code for obvious reasons (keeping it simple and easy to comprehend), therefore in a production version you will probably want to catch exceptions and validate the user's input.

Your application should now look such as the one attached to this tutorial:
