No, there is no such method in the framework.
If there were such a method it would not be in the Math class, it would be somewhere in the System.Drawing namespace where the Point structure is.
Despite everything, the person most likely to be fooling you next is yourself.

hi,
I have an application that will find Firefox browing history, Auto complete datalist, Temp offline files and Find Computer list.
please give me some idea on Auto complete datalist, Temp offline files and Find Computer list.
I tried this task using path
C:\documents and settings\eminosoft\Application Data\Mozilla\Firefox\Profiles\38v4t6d1.default
But in that path there are 4 .dat files
history.dat
formhistory.dat
persdict.dat etc.
what is the use of each file and if I want to delete auto complete datalist from firefox which file i will use?
Thanks in advance

hi i've created a form which edit & diaplayes data into a data grid..
when i save data through Save button click data gets saved but if i (after entering 3-4 records) press shortcut key as <Alt + S> last record from the data grid not get saved .. even this is not displayed in the datasource during debug ...
i added a code because datagrid doesnt displayed next column without hitting the keys on last column...
If dgdcoccmast(dgdcoccmast.CurrentCell.RowNumber, 0).ToString <> "" Then
Dim cm1 As CurrencyManager = Me.BindingContext(Me.dgdcoccmast.DataSource)
cm1.EndCurrentEdit()
End If
but the problem remains....
Please help

What code did you write to make this shortcut key work ? How has the debugger led you to believe that it should be saving ?

Sir,
its not the shortcut key code since this shortcut is just to focus the Save button '&Save' event is firing is the btnSave_click only.. but in the datatable which i m using & binding to datagrid is not considering the last record because user is not hitting any key to generate the new row in the datagid instead it just saving the data....
|
|
|
|
|
OK, so you need to write code that detects that a record has not been saved, based on key presses in the grid ?

No i just need to write a code which saves all the records edited or added new in the grid on the pressing of Alt + s keys
|
|
|
|
|
OK, so the code issue IS that you are pressing a key and you didn't write code to make it do anything ? I am confused....

Public Class Form1
Delegate Sub d(ByVal b As Boolean, ByVal b1() As Button)
Private Sub disablefunction(ByVal val As Boolean, ByVal ParamArray b() As Button)
For i As Integer = 0 To b.Length - 1
b(i).Enabled = val
Next
End Sub
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Me.Invoke(New d(AddressOf disablefunction), False, Button1, Button2)
End Sub
End Class
</pre>
I am getting the following error
Parameter count mismatch

It's sure VERY nasty that you're passing controls arround, but does ParamArray mean you can pass as many buttons as you like, or do you need to create the array and pas it ?
Is that really how you call a delegate in VB ? It looks nasty compared to C#

Pretty sure ParamArray is the equivalent of the C# params keyword. Regardless, his delegate signature is d(bool, Button) and he's calling it with two Buttons...
|

Christian Graus wrote: Is that really how you call a delegate in VB ? It looks nasty compared to C#
Not exactly. He's doing Me.Invoke, which would call a method on the main thread. From what I know, the same thing in C# would be (note that I've also fixed his problem here):
this.Invoke((d)disablefunction, false, new button[] {Button1, Button2})
|

ParamArray only works when you are directly calling the function. The arguments passed to a ParamArray parameter will always be converted to an array at compile time. When you are using Me.Invoke, you need to make the array yourself.
Me.Invoke(New d(AddressOf disablefunction), False, new Button() {Button1, Button2})
As a bonus, if you had declared the function as
disablefunction(ParamArray b() as object)
and called it as
disablefunction(new button() {Button1, Button2})
you would get a one element array that is an array of buttons.

Good day fellow codeproject.com'ers.
I am missing a vital part of theory which I've identified when I tried the below. (I believe it's theory...)
Please can one of you assist me by filling the theory gap I have. I've been through MSDN and Google, but to no avail...
Question:
Why can one not call a class from within another class? I don't mean within a function of a class, but at the top, where one declares variables pertaining to that class.
E.g. Below:
Friend Class Class1
Dim _message As String
Public Property Message()
Get
Return _message
End Get
Set(ByVal value)
_message = value
End Set
End Property
End Class
And here is where it fails, intellisense doesn't see the properties or methods of the variable (first class), I've labled the variable as THISDOESNTWORK.
Friend Class Class2
Dim _myVariable As String
Dim THISDOESNTWORK as New Class1
Public Property myVariable()
Get
Return _message
End Get
Set(ByVal value)
_message = value
End Set
End Property
End Class
It works when I place the code
Dim THISDOESNTWORK as New Class1<br /> within a function, so either there is a "secret way to do this", or I'm missing a bit of .Net/OOB Theory.
Thanks in advance...

class2 needs to be like this
Friend Class Class2
Dim _myVariable As String
Dim THISDOESNTWORK As New Class1
Public Property myVariable()
Get
Return THISDOESNTWORK.Message
End Get
Set(ByVal value)
THISDOESNTWORK.Message = value
End Set
End Property
End Class

Thanks again.

It should also be mentioned that your syntax might be a bit off:
Friend Class Class2
Dim _myVariable As String
Dim THISDOESNTWORK as New Class1
Public Property myVariable()as string
Get
Return THISDOESNTWORK._message
End Get
Set(ByVal value as string)
THISDOESNTWORK._message = value
End Set
End Property
End Class
or
Friend Class Class2
Dim _myVariable As String
Dim THISDOESNTWORK as New Class1
Public Property myVariable() as Class1
Get
Return THISDOESNTWORK
End Get
Set(ByVal value as Class 1)
THISDOESNTWORK= value
End Set
End Property
End Class
