VS 2008 Use The New Keyword To Create Object Instance
Apr 13, 2010VB is telling me to use the "NEW" keyword to create an object instance. For example: Private Sub ScoreTotal(ByVal sender..., ByVal e As System.EventArgs) Handles ListBox1.SelectedIndexChanged

When I run the "MainStudentScores" form and click on a student with three scores separated by the "|", it should give me a Score Total, Score Count, and Average. However it is giving me an error message at "Scores.Add(intPlaceHolder)" This is where VB is telling me to use the "NEW" keyword. Does this make sense?

May 31, 2012Using vb.net 2008.I have used the "Using" keyword before in C# with objects that implement iDisposable.Can you use that keyword in vb.net also? What are the advantages of the "Using" keyword other than showing the coder when the object goes out of scope.I am under the impression that the "Dispose()" function is called at the IL level when you use "Using" instead of, for examplel, calling the Dispose() in the .net code.

Flattening An Object Hierarchy Using A Shim Class - Initializing Derived Object Properties From The Base Object?
Jul 10, 2010I am somewhat new to object oriented programming and am attempting to flatten a Linq object hierarchy by using a shim class.how to initalize a derived class with property values from a base class?I have two objects, a base object with about 100 properties, and a derived object which inherits from the base object and adds a few additional properties beyond those of the base object. My simple constructor creates the derived object, but I am looking for a way to initialize the derived object properties with values from the base object.Right now I am using reflection to iterate over the properties individually and I suspect there may be a better way. The following example shows my shim class constructor for the derived class, and two properties:
newProperty1 - a new string property of the derived class
flattenedProperty2 - a new string property of the derived class, copied from a 2nd-level object of the base class
Code example:
Public Class derivedObj
Inherits baseObj
Private _newProperty1 As String[code].......
Is this the correct constructor approach to flatten the object hierarchy using a shim class? My second question relates to initialization of properties in the derived class. The constructor above creates the derived object, but what is the best way to initialize the derived object properties with values from the base object? The following code uses reflection to iterate over the properties individually, but I suspect there may be a better way.
Code example:
' property names are in the string array fieldNames
'baseObjQuery is an ienumerable of baseObj
'derivedObjList is a list of derivedObj[code].....
Is there a simple way to initialize values for the properties in the derived object based upon the values of the common properties in the base object?
.net - Does C# Have A Handles Keyword
May 25, 2011Protected Sub Menu1_MenuItemClick(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.MenuEventArgs) Handles Menu1.MenuItemClick

In VB.net, we have the Handles keyword, I'm wondering if C# has anything comparable. Or do you have to manually wire all the methods to each control's event (in ASP.NET especially)?

View 2 RepliesExtended With-keyword In .NET?
Oct 29, 2010In my current project everyone names variables and methods after what they are and what they do. This is good for quickly understanding the code, but with a lot of long varible names comes some headaches, such as when copying a dataset to an entity/object. So, while you understand the code, the readability still takes a blow.
veryLongVariableName.Id = datasetVeryLongVariableName.Id
veryLongVariablename.Something = datasetVeryLongVariableName.Something
etc.
Using VB.NET's With keyword can help.
With veryLongVariableName
.Id = datasetVeryLongVariableName.Id
.Something = datasetVeryLongVariableName.Something
End With
Now, my question, is there any way of using With, or something similar, but for several variables at the same time? Something like:
With veryLongVariableName As a, datasetVeryLongVariableName as b
a.Id = b.Id
a.Something = b.Something
End With
I'm all for descriptive naming conventions, but they do tend to clutter things. Especially in VB!

Use Call Keyword In VB / VBA?
Apr 4, 2010I use the Call keyword when calling subs in VB/VBA. I know it's optional, but is it better to use it or leave it off? I've always thought it was more explicit, but maybe it's just noise. Also, I read this on another forum: Using the Call keyword is faster because it knows that it is not going to return any values, so it doesn't need to set up any stackspace to make room for the return value.

Condition:
2 log files available in C drive that is C:/BSKYB/Prod.txt
and C:/BSKYB_CWE/many of log files in .txt format
Program Flow:
Step 1: The program will read the last sentence Hexa number from the file "Prod.txt"
Step 2: Once the program detecting the keyword like example "abcde" it will go to another folder which is descript in C:/BSKYB_CWE to look at which text files contains the keyword "abcde"
Step 3: this step will capture the whole line the text info like example 1111 abcde
if in this case, once the abcde detected what is the command i should apply to capture the key word 1111 ?
This is the problem i have encounter right now, i doesn't know how is actually can apply the right method to read the whole text line once the key word is detected
