In my grid view control I am displaying all the records in a table stored in data base. I am setting the attribute "AutogenerateDeleteColumn" to true, and I am handling "rowdeleting" event. one of the columns in data base have a file name stored in hard disk. when ever I delete a row, I need to delete that particular file from systems' memory. how can I do this in rowdeleting event ?
how can I fire "rowdeleted" event? is it possible to handle "row deleting" and "row deleted" events in same apllication?
thanks for ur suggestions,
with regards,
kiran

Create a MenuItem object set its properties according to your requirements then add it to your main menu then declare its Click event handler and use AddHandler to connect it with the click event of the created menu item object.
Hope it helps !

This is a question for the ASP.NET Forum. It really doesn't have anything to do with VB or VB.NET.

DataGridView Help... Manual Loading of ACCESS Records into DataGridView
I have read such an article and code about mannual loading of records from database into datagridview not by means of "DataReader and FOR LOOP" looping process to each rows and cells to put each corresponding value..
instead? he just use an OleDataAdapter to fill a DataTable and set the "DatagridView.AutoGenerateColumns = false" then he set DataGridView.DataSource = DataTable that he made..
for him it works.. but for me i dont know what's lacking in my code.. there's no error occur but the records doesn't display inside my pre-defined column inside my datagridview.. instead? it just generate a blank row with the same rowCount of my table inside my database..
but when i set my DataGridView.AutoGenerateComlumn = true?
then it display on system way.. but not in the way i wanted it to be display inside my custom column inside the datagridview....
here's my sample code...
************
Dim oleDataAdapter1 As OleDbDataAdapter
Dim OleCommandBuilder1 As OleDbCommandBuilder
Dim dbDataSet As New DataSet()
Dim tempDataTable As DataTable = dbDataSet.Tables.Add("tempTable")
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Try
oleConnection.ConnectionString = dbConnectionString
oleConnection.Open()
oleCommand = New OleDbCommand("Select * From tempTable", oleConnection)
oleDataAdapter1 = New OleDbDataAdapter(oleCommand)
OleCommandBuilder1 = New OleDbCommandBuilder(oleDataAdapter1)
oleDataAdapter1.Fill(tempDataTable)
With DataGridView1
.AutoGenerateColumns = False
.DataSource = tempDataTable
End With
Catch ex As Exception
MsgBox(ex.ToString())
Finally
oleCommand.Connection.Close()
End Try
End Sub
**************
Note:
I have 4 column created inside the datagridview..
columnName(ID,NAME,DATE,AGE) dataType(string,string,date,number)
I know.. you can laugh at me.. just can't figured it out.. ehehe... please help...
Please anyone there who has much deeper experience and knowledge in vb programming who can help me with this??? please.. a lot of appreciation in advance... please...

What does the column generation code look like?? You're probably missing setting the DataPropertyName for each column. This tells the column which column in the DataSource to bind to.

Sorry I'am from Mexico, my english es very mistaken.
I need mix Assembly language with VB 2005.
I need get a information of the PC ( RAM, HD size ) with
a aplication assembler and display the information in my
WinForm of Visual Basic 2005.
thanks for your aid !!!

You can't mix assembler into a VB.NET app. Besides, what you want can be accomplished much easier with Windows Manangement Instrumentation (WMI) and the classes in System.Management namespace.

All native machine code is already in machine language. You can write assembly code that is in a .dll and called from .NET. How to do so is beyond a forum post. There is an article around here at CP about it.

Yeah, it can be done. But how you communicate with that assembly code is entirely up to how that code is written. Without knowing how the assembly code expects you to call it and receive return values, it's impossible to say.
|
|
|
|
|
so, as I can create a DLL in assembly language?
where search Information about it ?
give me the URL or LINK please !!!
|
|
|
|
|
There is very little on assembly language under Windows because hardly anyone ever uses it.
Why are you fixated on assembly?? What are you doing that makes you think you require it?

Is a School project, is hibrida or hybrid programming ("programacion hibrida" in spanish). The teacher say: "Use Assembly Code with another language (mixing)". And i want programmin VB 2005 with Assembly language......
But the information is little.....if you can help me....i will happy
Thanks !!!

You're going to have to create two seperate project. An assembly language project compiled with an assembler, or you could write in-line assembly into a C++ component, which compiles to a .DLL, and a seperate VB.NET project to consume the library functions you write.
Google for "Windows assembly language" if you want examples.

Hi,
I haven't programmed in VB6 and I have this project to convert from vb6 Vvb.net
Can you help me to convert the following lines to vb.net
Public Declare Function DirectoryNumToTapiDeviceID Lib "tapihlpr" _
(ByVal hLineApp As Long, ByVal szDN As String) As Long
and
Public SysOptions As tSysOptsRec
Public iSystemStatus As Integer
' Per call data elements
Public iMaxChannel As Integer
Public iMinChannel As Integer
Public CallData() As tCallDataRec
thanks

Public Declare Function DirectoryNumToTapiDevice Lib "tapihlpr" ( _
ByVal hlineApp As Integer, ByVal szDN As String) As Integer
Public SysOptions As tSysOptsRec
Public iSystemStatus As Short
' Per call data elements
Public iMaxChannel As Short
Public iMinChannel As Short
Public CallData() As tCallDataRec
Of course, this does NOT mean that the code will actually work.
