Hi
my problem is in here
Public Class Person
Private _Name As String
Private _Title As String
Public Property Name As String
get
return _name
set (value..)
_name = value
In this property I have enterd Name once and _Name twice.
now this is fine for one or two properties but when you have 80 of these properties in a class and you need to create many classes then typing it in becomes painfull.
I think the code snippet will help but I was hoping for some kind of generator where
I could key in a list and have a class created for me with those properties set from the list.
End Class
thanks
Martin

A generator or two might exist, but I don't know of any. Try Googling for "VB.NET Property code generation".

Write another program that gets the name of the properties ,adds them to a list and finally makes the code for you to add to your class.
The function below may help you
Function Generate(ByVal mc As Collection) As String
Dim str As String
For i As Integer = 1 To mc.Count
str &= "Public Property " & mc(i) & "() As String" * vbCrLf & _
"Get" & vbCrLf & "Return MyDataCol(""" & mc(i) & """)" & vbCrLf & _
"End Get" & vbCrLf & "Set(ByVal value As String)" & vbCrLf & _
"MyDataCol.Remove(""" & mc(i) & """)" & vbCrLf & "MyDataCol.Add(value, """ & mc(i) & """)" & _
vbCrLf & "End Set" & vbCrLf & "End Property" & vbCrLf
Next
Return str
End Function
where mc is a collection of property names

Nah. I hate copy and paste coding and refuse to use such a technique in an addin. I'd much rather have the addin write, and if need be, rewrite the property code for me, directly in the CodeDom, when I change the member variables.
|

|

you can rewrite the property??
Is this a special VB way or "Just" writing a program to read in the .vb file and change it then save the new file overwriting the old one??
thanks

No. This would be a VS AddIn (not for Express though!) that manipulates the document object model that is your code, otherwise know as CodeDom. Search for that term on MSDN and you'll come up with all kinds of information.

wow I never knew that existed
NET is getting bigger and bigger - sigh - brain overload!!
Thanks for that - very interesting

Are you using .net 1.1 or 2.0? If you are using 2.0 you can use generics
Public Class MyProperties
Public Property1 as string
Public Property2 as string
End Class
Dim list as new list(of myproperties)
You then then access the properies in a strongly-typed way
Dim name as string = list(0).MyProperty1

hi,
I am on version 2
I think this is the same as the array solution
it would look something like
public property Name as string
get
return list(0).Myproperty1
..........etc
I need to relate property Name to Index position 0 in this case.
In my current development I will need about 30 of these clases averaging 20 of these properties per class. The worst class will have 80 or so properties.
I am really looking for something like
public property Name as string
get
return <obj>("Name") 'where <obj> is some classed object
...............
I could use collection but writing back changes is upgly (removing the item then adding it again - yuk)
I could use arrayLists as in return ArrayList.BinarySearch("Name") but I have to keep
the arraylist sorted and am wondering how fast the binarysearch will be compared
to the collection name index. Although knowing microsoft its probably the same code.
and then I am looking for some quick n painless way to actually type in these classes into visual studio.
Thanks
Martin

Hello
How to get colored area in the center (from the top and all way down) of page. I have tables (centered) on the page. Now I want to get the colored area that covers always the whole page center (10px wider than a table) area but all way down even if the table is on the top part of the page. I am doing a home page with vb.net.

www.pinvoke.net[^] is a good place to find p/invoke signatures. Or there are online sites that convert small snippets between the two languages.

please give me some code or sample on how to make a button on a datagrid cell. thnx!
|
|
|
|

hi,
you can make a button on datagridview very easily at desigen time.
when you add a column to datagridview , change its type to DatagridViewButtonColumn.
if you want to add column at run time then use following code
Dim ColumnButton As New DataGridViewButtonColumn<br />
columnButton.headertext="Your Heading"<br />
DataGridView1.Columns.Add(columnButton)
Hope this helps

i want to know both ways... can you please tell me how could i be able to do that on design time? thank you so much!
|
|
|
|

after adding buttonTypecolumn to datagridview ,perform following action
suppose index of buttonTypeColumn is 5 (whether you add column at design time or run time)
Private Sub DataGridView1_CellContentClick(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DataGridView1.CellContentClick<br />
If e.ColumnIndex = 5 Then<br />
msgbox "Button Type column of Datagridview is clicked"<br />
endif<br />
<br />
end sub
hope this helps

Howdy,
The physical database file limit for Access XP is 2 gig. What is the specific problem you are running into?

What is the error? Is it 'invalid argument?'
