First off let me say that I am essentially new to VB.NET, i.e; still learning. Also, I hope that this is the right place to post this question. In a Project I have a Class module defined as:
Public Class Def
Public Id As String
Public Meaning As String
[Code]...
What is the advantage of using USING keyword in vb.net??im new with the USING and it seems that most people are using this.

View 10 RepliesI'm trying to make the combobox get suggested values from a website using the current keyword they have in the box already. For example if I have O, it will show up values that the website has returned with O. The problem is how can I make it work where whatever I type into the combobox, it will get the values, set the datasource and make it show up. So far I have this:The problem is whenever I type something, I cannot get it to set it to the new datasource without the comboxbox becoming the first value in the data source.
Dim pop As New List(Of String)
pop.Add("Koolaid")
pop.Add("kIMKY")
pop.Add("KoolPaid")
ComboBox1.DataSource = New BindingSource(pop, Nothing)

View 4 Repliesthis is essentially the code in a class module I added to the project.

The problem is this: NullRefereceException was unhandled - Use the "new" keyword to create an object instance.So I've tried placing the word "new" in various locations in front of references to any picturebox to no avail. I even tried to add this before the ** line:
Maps(1).Tiles(1, 1).pctrbox = New PictureBox
In which case the same error moves up to that new line instead. That seems entirely baffling, because VB is telling me that I need a "new" keyword when it is clearly there. I expect either it is in the wrong spot or I'm declaring something incorrectly.

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 RepliesIn 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!

I 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.

View 2 RepliesI'm still new in VB.net development environment, i've few of the question may need the advice from you guys to see whether i'm in the right track for the development as below condition:Basically my program wrote from this logics:
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
Public Class Form1
' Const ConstBSKYB = "C:BSKYB_CWE.txt "
'Const ConstBSKYBP = "C:BSKYBProd.txt"[code].....
