Is using a TryCast() and then checking for Nothing the best way?
I am using a PropertyGrid control to edit my class properties and I am trying to set certain properties read-only depending on other property settings.This is the code of my class:
Imports System.ComponentModel
Imports System.Reflection
Public Class PropertyClass[code].....
This is the code I am using to edit the values:
Dim c As New PropertyClass
PropertyGrid1.SelectedObject = c
The problem is that when I set SomeProperty to True, nothing happens and when I then set it to False again it sets all properties Read-Only.
I am trying to set the an entire row readonly if one of the fields is set to true. I have a checkbox on column 6 which is either ticked or not. Therefore, if the checkbox is ticked i.e., set to TRUE then the entire row should be READONLY.
Dim irowDatePaid As Integer
For irowDatePaid = 0 To DgvReturns.Rows.Count - 1
If GetBool((Me.DgvReturns.Rows(irowDatePaid).Cells(7).Value) = True Then
[code].....
The row is set to readonly fine. However, in 3 columns I have checkboxes which are not set to readonly. Is it possible to set enable = false for these checkboxes..
Protected Sub Menu1_MenuItemClick(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.MenuEventArgs) Handles Menu1.MenuItemClick
End Sub
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 m trying to create a software in vb.net for some genealogists to trace their ancestors History, the users will search for the document in 3 ways

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 4 RepliesI have a user control and I'd like to give it a custom property named ReadOnly. I get "Keyword is not valid as an identifier", as it thinks I'm writing a ReadOnly Property named something.
so really I can call mine 'Read_Only', but I'm just curious if there's an easy way to get the other name in there, since then my control will be similar to the visual controls that have ReadOnly in the designer.
What ever happened to the readonly method in the ComboBox? So i thought if MS did not have that option let me code around it. So i made a code here that checks if the user inputs something else then what i want him to input.If it something else is found it returns the text back to "Hours(s)"
View 2 RepliesHow do I make it to where you cannot type into a combobox, but you can choose items through the drop down? I tried Readonly, but it makes it so you can't type AND can't drop down select.
