Hi:
I have created two dimensional 2 x 2 array, and assigned values for 3 elements of an array only which is shown in the following code. I was bit wondering what values will be stored in the rest of the elements of array. I assumed "nothing"
will be stored for them. But I got some exception handling errors. Can any help me?
My Code:
Dim s(2, 2) As String
Dim x As String
s(0, 0) = 1
s(0, 1) = 1
s(1, 0) = 1
x = s(1, 1)
If x.Equals("") Then
MessageBox.Show("Uninitialied arrray stored nothing")
End If

They will contain Nothing, or in C#, null.

Hey:
If they contain nothing, can you tell me why I'm getting unhandled exceptional error while running my code?
Dim s(2, 3) As String
Dim x As String
s(0, 0) = 1
s(0, 1) = 1
s(1, 0) = 1
x = s(1, 1)
If x.Equals(Nothing) Then
MessageBox.Show("The value of x is :" + x)
End If
|
|
|
|
|
probably because of this line:
MessageBox.Show("The value of x is :" + x)
you can't add/concat x because it is nothing. just say this:
MessageBox.Show("The value of x is : Nothing")
|
|
|
|
|
No. I tried what you have suggested but it showed me some exceptional handling errors.
The debugger is showing an error at:
If x.Equals(Nothing) Then<br />
|
|
|
|
|
Try:
If x = nothing Then
or
If x Is Nothing Then
|
|
|
|
|
Thanks man! It works well now.
|
|

Because in order to execute the Equals method on X, X actually has to have a reference to an object. It doesn't, so the exception, which you haven't told us anything about, should be "Object reference not set to an instance of an object."

Hi all,
How could i know Window is English version or Japanese version or Chinese version through vb.net code?

You can look at the current culture of the UI using:
Imports System.Globalization
.
.
.
Console.WriteLine("Current UI Culture: " & CultureInfo.CurrentUICulture.Name)

Hi,
I had a bit of a trawl through MSDN for this and I think this is what you want.
Click Here
The part you probably want to look at is...
"Use the LanguageDesignation property to return a three-letter abbreviation for the language used for the operating system. The following statement returns "enu" as the language designation abbreviation for the English (US) language.
currSystemLanguage = System.LanguageDesignation"
Let me know if this is of any use.
Regards
Guy;)

That's not part of the .NET Framework. That's a FrontPage library.

I'm hoping this is an easy question. I am converting data from and reading specific strings and replacing certain characters with other characters.
For example, currently I'm replacing a & symbol with a | symbol using the following code.
dim strTest as string<br />
... load strTest with a value from SQL ...<br />
strTest = Replace(strTest, "&", "|")
The code above works fine. Now, my question is, what do I do if the string has a " symbol in it. I want to replace the " with a | symbol. The code would look like this, but of course the compiler doesn't like this syntax.
strTest = Replace(strTest, """, "|")
Single quotes don't work either because the compiler recognizes this as a comment. How do I code a double quote?
Thanks for any help

You need to use 2 double quotes to tell the compiler that this should be interpreted as part of the string.
strTest = Replace(strTest, """", "|")

should be:

Thanks to both of you. I tried out the logic and it worked!
Thanks again

The shell command is useless. You need to use the visual studio tools for office to control Excel from yuor code.

Hi folks,
How do I change my application settings so that they are displayed properly as per the resolution. For example, I design an application with a 1024 x 768 resolution and then port my application to a system having 1280 x 1024 resolution. My application occupies the top left corner of the screen without getting maximized as per the current resolution.
You get the picture and now give me your resolution 
Vinod
