My first question would be what are you trying to do with it?

Since the proc is switched to 32-bit flat addressing, the segment and offset address you specified doesn't have any meaning. Also, you can't just read any memory you want from anywhere. Various areas are protected, such as the kernel. And, each process get's it's own address space, essentially making it think it's the only one running on the system.

Hi All,

I am developing a single project application using VB.Net. I have added a “resx” file to the same project. But I don’t know how to create instance of that file. One of my friend has told me that I can create instance using Resources.ResourceManager. But I don’t know how to use it. Can anybody help me in this regard.

Regards,
Krishnaraj

How to show a hidden window with a shortcut key

re infecta31-Aug-06 2:12

re infecta

31-Aug-06 2:12

Hello,

I have added a notify icon component along with a context menu. I'm using these to be able to hide/show the main form of my application. I was wondering is it possible to make the window appear with a shortcut key (e.g. by pressing F11)? The problem is that when the main form is hidden [Me.Hide()] the KeyPress events are not working. I think this is because the form is "out of focus" and therefore can't monitor keypresses. Can you come up with a solution? Maybe with a timer?

With best regards,
R.I.

Here's a small example. I hope it does what you're looking for.

Try this using 2 forms. In Form1 add a button control & this code

Private Sub Button1_Click(...) Handles Button1.Click
       'open form2 & hide the startup form (form1)
       Dim f2 As New Form2
       Me.Hide()
       f2.Show()
   End Sub

Then in Form2 on the KeyUp event add this code

Public f1 As Form1

  Private Sub Form2_KeyUp(...) Handles Me.KeyUp
      'show the main form after pushing F11
      If e.KeyCode = Keys.F11 Then
          f1 = Application.OpenForms.Item("Form1")
          f1.Visible = True
      End If
  End Sub

Hope that helps.

Another way to accomplish this is to use a menu control. Make a menu item that uses a shortcut key, and then set that menu item's visible property to false. This will cause it not to show up in the menu, but whenever you press the shortcut key you assigned to it, the on_click event will fire.

I would actually advise you to use the mclHotKey component, found here :

hi,
how can we import data from an excel file to dataset using VB.Net
can u send the code
can u help me

Something like this:

Dim DS As System.Data.DataSet
Dim MyCommand As System.Data.OleDb.OleDbDataAdapter
Dim MyConnection As System.Data.OleDb.OleDbConnection

MyConnection = New System.Data.OleDb.OleDbConnection( _
"provider=Microsoft.Jet.OLEDB.4.0; " & _
"data source=C:\myData.XLS; " & _
"Extended Properties=Excel 8.0;")
' Select the data from Sheet1 of the workbook.
MyCommand = New System.Data.OleDb.OleDbDataAdapter( _
"select * from [Sheet1$]", MyConnection)

DS = New System.Data.DataSet()
MyCommand.Fill(DS)
MyConnection.Close()

NOTE: You will need to provide the correct Excel version for the Extended Properties Value. Needs reference to System and System.Data Namespaces.

To reference the complete used range of a worksheet, specify the sheet name followed by a dollar sign:
select * from [Sheet1$]

To reference a specific range of addresses on a worksheet, specify the sheet name followed by a dollar sign and the range:
select * from [Sheet1$A1:B10]

To reference a named range, use the name of the range:
select * from [MyNamedRange]

If you need to retrieve worksheet formulae, you will need to use Excel automation.

Do you need to create a new table each time you import this data or is there a table that needs to be updated with the new data?

thanks in advance

You cannot decrypt a hashed password.

The method to use is to compare the password entered by the user with the hashed password in your database. When the user enters a password, hash it and compare that hashed value with the values in your database to authenticate your user.
