Hi, IMO the best way to learn a new language is to buy a book and work your way through it.
That way you will get all the essentials in a short time, both explained and illustrated.

No but there is an easy way to comment and uncomment blocks of code. Just highlight the code and press the toolbar item that does that and it will put ' infront of all the lines of code you highlighted. Same goes if you want to uncomment a block of code.

Entirely depends on your requirements did you search Code Project first for this and then Google because it gonna take allot of your time.
eyes2007 wrote: why should microsoft has to make two different controls like checklistbox and listbox.
Because both of these controls are for different requirements and one has advantage over the other e.g. you can't bind data to the CheckedListBox control for this you have to use either ComboBox or Listbox and also not support for Multi Selection whereas in ListBox Control you can't display a Checkbox besides every item.
Hope it helps !

Hello
I'm trying to communicate with an application written in C++ that receives windows messages. The problem is that i need to pass a pointer to a structure from VB.
In C++ the code to send a message looks like this (works fine)
BOOL bRC = false;
COPYDATASTRUCT cpd;
cpd.dwData = MESSAGE_1;
cpd.cbData = 0;
cpd.lpData = 0;
bRC = ::SendMessage(m_hServer, WM_COPYDATA, (WPARAM)NULL, (LPARAM)&cpd);
I've tried using marshaling this way in VB but doesn't work:
Dim bo As Boolean
Dim data As CopyData
data.dwData = MESSAGE_1
data.cbData = IntPtr.Zero
data.lpData = IntPtr.Zero
Dim ptr As IntPtr
ptr = Marshal.AllocHGlobal(Marshal.SizeOf(data))
Marshal.StructureToPtr(data, ptr, False)
bo= SendMessage(server, WM_COPYDATA, IntPtr.Zero, ptr)
Any ideas? thank you.

How can I make the system sleep for a while so that in the meanwhile my files get populated with some data and after that I can access the file for processing. Is there any way in vb.net or I have to call some API functions ?
Thanks in Advance.

System.Threading.Thread.Sleep(1000) '1000 Milli Second delay
Or you can use a different thread to do the population of the files.
Private Sub PopulateFiles<br />
.....<br />
End Sub
Use the lines below in one of your Procedures, which then calls the PopulateFiles procedure on a new thread.
Dim thPopulateFiles As New System.Threading.Thread(AddressOf PopulateFiles)<br />
thPopulateFiles.Start()<br />
It can be tricky if you access the file before the new thread has finished executing - maybe look at Thread.Join as well.

Hi
I have a small app using the IO.Ports.SerialPort class. (VS2005 - Visual Basic)
Can anybody point me in the right direction to make this app MONITOR data transfer on a particular port in both directions, but not interfere it.
So basically if I have an application communicating with an external device on a particular serial port, I want to be able to log the data that the app sends to the device and the data the device sends back to the pc, but it must not interfere?

Hi Guys. I am trying to convert the following bit of code to C# which I got from a mate of mines but I keep getting an error message. Can anybody please tell me what is wrong with it? I keep getting the Error "Invalid StructureMemberDecl.
Public CNCatalogue as String = "jhbmsql16"
Public CNDataSource As String = "TakeOn"
Public CN As New SqlConnection("Initial Catalog=" & CNCatalogue & ";Data Source=" & CNDataSource & ";Integrated Security=SSPI")

This code does not contain any error there must be something else in your code that raised this error.

Why you are assigning a 'String' when it takes a Structure in this case an Item and create an object of the structure before assigning it a value.
Hope it helps !

This code may help u to understand the concept:
Structure Item
Dim A As String
End Structure
Structure Item1
Dim a As Item
End Structure
Dim Value As Item
Dim Value1 As Item1
Sub STExample()
Value.A = "Some String"
Value1.a = New Item()
Value1.a = Value
End Sub

MrFulvio wrote: value1.a(1)="item"
value1.a is null/nothing as long as you don't create an array; you must provide memory
(using new) before you can store anything!

'Dotfuscator' can make your assemblies difficult to reverse engineer. If you are using VS 2005 Professional Edition then its already installed under Visual Studio Tools menu I don't know about other versions of VS.
Hope it helps !
