Thank you both... I removed the message.

I want to binary serialize a class, which has only shared items (variables & objects of different types) which I use globally in my code. When I want to serialize it, I get the error "'EmailAccount' is a type and cannot be used as an expression" : binformatter.Serialize(filstream, EmailAccount) I even tried to create an object from the class and serialize it. But it seems to only save the instance variables and not the shared ones. Is there a way to serialize them?

I want to binary serialize a class, which has only static items (variables & objects of different types) which I use globally in my code. When I want to serialize it, I get the error "'EmailAccount' is a type and cannot be used as an expression" : binformatter.Serialize(filstream, EmailAccount); I even tried to create an object from the class and serialize it.

I want to connect to my full SQL Server 2008 SP1 on a remote server over the internet using both VS.NET server explorer and MSSQLServer Management, and in both I failed! I tried all the steps described in http://msdn.microsoft.com/en-us/library/ms345343.aspx[^] but I still cannot even telnet the remote server on the ports (1433 or the one I assigned as in the tutorial: 49172) ... BUT I can ping it and it replies. I even closed the firewall application (NOD) on the server as I have full administrative remote desktop access to the server, and still no progress. (And I easily can connect to server using remote desktop) I really need to connect to the server using SQL Server Management. Thank you all

Hi, I had a large folder on drive E:, which suddenly I found missing (today 08/25/2009, I had a security update, but I am not sure whether my folder was missing before or after the update). I am sure that I have not accidentally deleted the folder because the free space of my drive has not changed. On the other hand, System Volume Information now, is the same size as my folder was (i.e. 19GB). I am pretty sure that my folder is in SIV though. By the way, My OS is Windows 7 RC Build 7100. Is there any way I can recover my folder? (I am not sure whether this is the right forum to ask my question, but if not, I hope you can lead me to the correct spot) THANKS

Try making a windows service instead of a windows application.

The method you are using (and was suggested in my link) works for ActiveX Dlls and OCX objects. First, have your class library a module not a class:

Public Module TestDll
Public Sub Test()
MsgBox("Hi")
End Sub
End Module

Then use LoadLibrary to load the dll.

Delegate Sub Tst()
.
.
.
Static dll_loaded As Boolean, dll_handle As Int32, fn As tst
dll_handle = LoadLibrary("Testdll.dll")
msgfn = GetProcAddress(dll_handle, "Test")
msgfn.Invoke()

By the way, why do you want to late-bind? Try using

Declare

which makes it much faster and more reliable!

If I have understood you correctly, you might use commandline parameters to run your application, or as mentioned by crudeCodeYogi, by using parametrized constructors.

The equivalent vb code is:

  Dim info as New FileInfo(fileName)
  Dim isFolder As Boolean = info.Attributes And FileAttributes.Directory

If IO.File.Exists(Path) Then
   'It is a file
ElseIf IO.Directory.Exists(Path) Then
   'It is a folder
End If

see http://www.omegajunior.net/code/vbnet_unmanaged.html[^]

Could you be more specific? You may use .Dispose method to delete objects.

Found the solution:

<bindable(false), EditorBrowsable(EditorBrowsableState.Never), Browsable(False)> _
    Public Shadows Property GridType() As GridTypes
        Get

        End Get
        Set(ByVal value As GridTypes)

        End Set
    End Property

Hi I have a Base class which exposes some public properties, and I derive a second class. I want the second class, not to have some of the public properties of its parent. (I don't want to use Shadows statement to create a new empty property, I want to hide it completely) Could you please help me?

No, a richtextbox (as it is) cannot be split. But you may have a control, which consists of two richtextboxes and a seperator between them. You may program different interactions between these two controls to give the user the feel that they are one split richtextbox (if you need such thing).

In the path that you save your project, delete all files whose extension is not as the known formats, e.g. if you have Form1.frm, then (if I remember correctly) Form1.frk or something like that is also created. Also one extra file is created with the name of your project, but without .vbw extension. I can remember that if you delete these files, you would get what you want.

Hi I have a very large file in whose format is like this: KEYWORD SomeInformationLines KEYWORD SomeInformationLines I need to pass through the file and save the position of each keyword, so that when later, user wants me to read the keyword data from the file, I can seek to the position of the keyword and read the data. The problem is some files are unix format (i.e. their lines end with linefeed, Chr(10), only rather than CR-LF, Chr(13)+Chr(10)). This is My Code:

	FileOpen(1,FileName)
	
	Do Until EOF(1)
		strLine = LineInput(1)
		If IsKeyword(strLine) Then
			SaveKeywordPosition( strLine, Seek(1) )
			' The above line is where the bug comes from:
			' e.g if the line is empty, and only an LF is in it, Seek(1) returns 2!!
			' i.e. it virtually adds a CR and this is done for all further lines too.
			' But whem I use Seek(1, aPreviouslySavedPosition) it goes exactly to where
			' it should go, without accounting for extra CRs which it added while reading
                        ' the file.
		End If
	Loop
	
	FileClose(1)

I also have tried to with InputString function, StreamReader and FileStream classes and check the last character of the line manually, but the IO was raises from 800KB/s to 18MB/s and runtime from 15sec to 2min. Could someone please tell me how should I handle this?!

My.Computer.Scree.MousePointer=Cursors.WaitCursor

Why are you still using this totally abandoned way of error handling?!!! Use Try...Catch instead: Try . _YourCodeHere_ . Catch ex1 As DataException Catch ex2 As IOException Catch ex3 As Exception Finally . . . End Try

Thank you! This looks so fine!
