You can use System.IO.Directory class to create a directory. The code below demonstrates how you check that the directory doesn't already exist, how to create it, and when it is created how you can then get a reference to the created directory (a DirectoryInfo object) Code Snippet If System.IO.Directory.Exists( "C:\MyDir" ) = False Then Dim dir As System.IO.DirectoryInfo dir = System.IO.Directory.CreateDirectory( "C:\MyDir" ) End If Tag: Visual Basic Express Edition cool webbrowser discovery!

    - NotifyIcon mouse position always zero? Yes, the NotifyIcon Windows message handler fires any of the mouse events with the mouse position hard-coded to 0,0. Educated guess as to why: it gets the mouse coordinates relative from the Tray window. Since the shell doesn't let you find out where the icon is located in the tray, Windows Forms can't calculate the mouse position relative from the icon's upper left corner.

    - Many Threads Logging to Same File(?) The filestream open method has an overloaded method in which you can specify the share mode: public static System.IO.FileStream Open ( string path , System.IO.FileMode mode , System.IO.FileAccess access , System.IO.FileShare share ) Member of System.IO . File Summary: Opens a System.IO.FileStream on the specified path, having the specified mode with read, write, or read/write access and the specified sharing option. Parameters: share : A System.IO.FileShare value specifying the type of access other threads have to the file. mode : A System.IO.FileMode value that specifies whether a file is created if one does not exist, and determines whether the contents of existing files are retained or overwritten. access : A System.IO.FileAccess value that specifies the operations that can be performed on the file. path : The file to open. Try specifing a readwrite share ReadWrite Member of System.IO . FileShare Summary: Allows subsequent opening of the file for reading or writing. If this flag is not specified, any request to open the file for reading or writing (by this process or another process) will fail until the file is closed. However, even if this flag is specified, additional permissions might still be needed to access the file. Tag: Visual Basic Express Edition cool webbrowser discovery! Visual Studio Express Editions

    - How to use the DataReceived event which was defined in a module. VickyLoe, According to your question on using System.IO.Ports.SerialPort.DataReceived event to get the bytes, I would like to provide you the suggestions as follows: 1. Serial Communications Usually when I do serial communications, I set up an event handler for the comm port's data received event. Then I get the data whenever it comes in and usually will resend my output until I get a response or send it too many times, at which point I timeout, close the port, and raise a timeout event. The code could look something like this: Code Snippet Dim WithEvents port As New SerialPort( "COM1" ) Private Sub SendData( ByVal data As String ) If Not port.IsOpen Then port.Open() port.Write(data) End Sub Private Sub port_DataReceived( ByVal sender As Object , ByVal e As System.IO.Ports.SerialDataReceivedEventArgs) Handles port.DataReceived If e.EventType <> SerialData.Chars Then Exit Sub Dim inData As String = port.ReadExisting 'process incoming data here End Sub 2. How does SerialPort handle DataReceived Please see the answer by nobugz: The call to your DataReceived event may well be delayed, depending on system load. By the time it runs and you use the BytesToRead property, you may be seeing bytes received for which SerialPort has already queued new thread pool worker items. That means that you may well see zero bytes (because they were read by the previous invocation of the event). Also, the the number of bytes may change right after you call it in the middle of your DataReceived event's execution when another byte was received a few microseconds later. 3. Example from code project: Communication on a serial port in NET 2.0 Code Block Imports System Imports System.IO.Ports Public Class Form1 Dim WithEvents port As SerialPort = New _ System.IO.Ports.SerialPort( "COM1" , 9600, Parity.None, 8, StopBits.One) Private Sub Form1_Load( ByVal sender As Object , ByVal e As _ System.EventArgs) Handles Me .Load CheckForIllegalCrossThreadCalls = False If port.IsOpen = False Then port.Open() End Sub Private Sub port_DataReceived( ByVal sender As Object , ByVal e As _ System.IO.Ports.SerialDataReceivedEventArgs) Handles port.DataReceived TextBox1.Text = (port.ReadTo( "!%" )) If port.ReadExisting.Length = 0 Then ListBox1.Items.Add(TextBox1.Text) TextBox1.Text = "" End If End Sub End Class Hope that can help you.

    - Troubles with timer I could do with a little more information about when the timer will be started, but assuming it starts at run time (thus making your splashscreen2 the first form that's shown) this would be the rough code: For Timer on the Splash Screen Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick Me.Hide() Form2.Show() timer1.Enabled = false End Sub Use these settings for the timer and put it on the splash screen: http://i4.tinypic.com/62p71h0.png What is this doing When your splash screen loads, the timer will count up to 5000 (5 seconds) then hide itself and show form2 (for you will be form6) It also disables the timer so that it doesn't keep doing it every 5 seconds, as your splash screen will still be there, just hidden.

    - Database Project in VB2005EE again/still CamPeck, I notice that you have the SqlConnectionString by DataSet and manipulate database with the DataAdapter. I think you have no problem on data binding on the ListBox because you have exact DataSource for it. For your TextBox data binding, I suggest you to add some certain code like <%# DataBinder.Eval(Container,"DataItem.TableField") %> in your text property for the TextBox controller. This is just like one of my project and this code written in Label controller text property and make the data bound to the Label controller. Hope that it can help you.

    - Prompt at program close question? Try this: Code Snippet if(textBox1.Text == "" && textBox2.Text == "") this will evaluate to true when both textboxes are empty. As for your second problem, I believe this is happening because the call to Application.Exit is causing Form2's Form_Closing event to fire again - and since the textbox still isn't empty, a new instance of Form3 is created again ... You could alternatively, use the MessageBox to obtain the Yes/No result and simplfiy your eventhandler to the follwoing ... Code Snippet private void Form2_FormClosing( object sender, FormClosingEventArgs e) { e.Cancel = true ; // allow the form to close if both textboxes are emtpy, otherwise // prompt the user first, if they respond with OK, go ahead and exit if ( ( this .textBox1.Text == "" && this .textBox2.Text == "" ) || MessageBox .Show( "Are you sure you want to Exit" , "Exit " , MessageBoxButtons .OKCancel) == DialogResult .OK) { e.Cancel = false ; } } Tag: Visual Basic Express Edition cool webbrowser discovery!

this is how to do it! step by step!,

1. add a toolstrip and make a toolstriptextbox,

2.add a toolstripbutton,

3.double click the button on your toolstrip, and make this code,

Private Sub ToolStripButton8_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ToolStripButton8.Click
WebBrowser1.Navigate("http://www.google.com/search hl=en&q=" + ToolStripTextBox2.Text + "&btnG=Google+Search")
End Sub

Re: Visual Basic Express Edition cool webbrowser discovery!

Chris

That's a cool discovery. It's probably the easiest way to google search from a web browser in VB. You could also make the browser navigate to google, auto-fill the textbox, then press the search button. Its a lot more complicated, so I would probably suggest using your method in most cases.
