The answer you have gotton before is good but if you wanted to select a file and open that selected file..you could use this one also..
drag and drop a openfiledialog control to your form... and use the following code..
<big>If OpenFileDialog1.ShowDialog() = DialogResult.OK Then<br />
System.Diagnostics.Process.Start(OpenFileDialog1.FileName)<br />
End If</big>
using this method... opens any file that is selected in their own program...and also a new window..

Where are you struggling? What have you tried? How have you attempted to organize the data?

Looks like a school project.
You may want to consider collections, and hashtables?

I need a script to get the name or path on a active window opened.This i need to run on a Pop-up Web page opened to display an Image.This image i have uploaded to this site. The Pop-up window does not include a Address to copy the path. I need a VBscript to automatically get the title so the i can put it in clip board.

You can use FindWindow function within user32.dll. It will return window name and handle. I am not sure how to impliment it

hi priya,
see this code I hope it will give some idea about mysql+ado.net using Vb.net
Dim connectionString As String = "Driver={MySQL};SERVER=localhost;DATABASE=NorthwindMySQL;"
Or you can use an ODBC DSN, as you can see from the following code that I've used TestDSN DSN to connect to the data source:
Dim conn As New OdbcConnection("DSN=TestDSN")
Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs)
Dim connectionString As String = "Driver={MySQL};SERVER=localhost;DATABASE=NorthwindMySQL;" '
Dim conn As New OdbcConnection(connectionString)
conn.Open()
Dim da As New OdbcDataAdapter("SELECT CustomerID, ContactName, ContactTitle FROM Customers", conn)
Dim ds As New DataSet("Cust")
da.Fill(ds, "Customers")
dataGrid1.DataSource = ds.DefaultViewManager
conn.Close()
End Sub

a DgvCustList.databind() should solve your issue.

I am using VB.NET with Ms Access and Ms Excel, how can i diplay Table name or amount of sheets,
Socheat
................

|

Socheat,
MS Access is different from excel.
Excel Using OLE connection:
Public Class XcelFileReader
Const testStr As String = "Provider=Microsoft.Jet.OLEDB.4.0;" & _
"Data Source={0};" & _
"Extended Properties=""Excel8.0;HDR=No;IMEX=1"""
'NOTE: Imex =1 Reads all value as typeof(string)
Protected Sheets As ArrayList
Protected cCon As OleDbConnection
Public Sub New(ByVal file As String)
cCon = New OleDbConnection(String.Format(testStr, file))
Sheets = New ArrayList()
Try
cCon.Open()
System.Diagonstic.Debug.WriteLine(cCon.GetOleDbSchemaTable(OleDbSchemaGuid.Tables,Nothing).Rows.Count.Tostring())
Finally
If cCon.State <> System.Data.ConnectionState.Closed Then cCon.Close()
End Try
End Sub
End Class

I have just upgraded a Visual Studio 2002 Windows application project to Visual Studio 2005, including upgrading to the latest custom controls.
The compiled application runs fine but on exit I get a windows message box with my application's title in the title bar and the message:
The exception unknown software exception (0xc0020001) occurred in the application at location 0x7c812a5b
This happens after the last line of code has run so as a total guess it's something to do with garbge collection.
Then I run in the Visual Studio 2005 environment I don't get this error (or any others).
The application uses Crystal Reports, Dundas, Devexpress and Infragistics controls.
My only lead so far is that if I get the application to display on screen one of the Crystal reports then the error doesn't happen on closedown. I'm looking through this code to see what I can see but there's quite a lot of code and I don't know what I'm looking for.
Any help welcome.

Hi.
How do I search anything in datasets or datatables? Are there any methods for this?
WofR
|
|
|
|
|
By searching, I assume you are referring to searching records.
If so then,
Dataset - Cannot really search records in a collection of datatables!
Datatable - you can create a view out of it and apply a filter on it.

You can create a BindingSource if you haven't already and do the following:
MyBindingSource.Position = MyBindingSource.Find("Column Name",Key)Where key is the primary key value of the record you require.
This code will cause the BindingSource to jump to the specified method, if you don't want to jump, don't set the .Position property. The .Find property returns an index to the BindingSource's list.
you can't forget something you never knew...

Depending on what you are doing the DataSet.Select(string) function can be usefull. Where String is the where clause of a SQL Statement, AND not to terribly complicated.
