    - Web Browser Detect Link on Hover OK. Ready for some hovering action Step 1. In your browser's navigated event handler, place the following line: this .webBrowser1.Document.MouseOver += new HtmlElementEventHandler ( this .Browser_Mouse_Moved); This will hook up the event of moving your mouse over the browser to a new event handler that looks like this: private void Browser_Mouse_Moved( object sender, HtmlElementEventArgs e) { string element = webBrowser1.Document.GetElementFromPoint(e.ClientMousePosition).GetAttribute( "href" ); label1.Text = element; } The event handler gets the html element that the mouse is over, a method looks for a reference to a link and displays the result in a label. (You may need to change this to another label name you have.) It now works pretty well. Tag: Visual Basic Express Edition password string question Visual Studio Express Editions

    - turning a "textbox" into a "numberbox" are you just wanting numeric data to be entered into a textbox if so then you need to check the key pressed in the KeyPress event of the textbox. Example: private sub Textbox1_KeyPress(byval sender as object, byval e as KeyPressEventArgs) handles Textbox1.KeyPress if Char.IsDigit(e.KeyChar) = false AND Char.IsControl(e.KeyChar) = false then 'cancel the input e.Handled = true end if end sub you should also use the Convert class to convert to your data type you like rather than using the old VB methods. Convert.ToDecimal( StringInput ) for example ;-) Tag: Visual Basic Express Edition password string question Visual Studio Express Editions

    - serial port in C# (Overflow in hex? ASCII?) The default encoding used by SerialPort is ASCII. That encoding doesn't support codes higher than 0x7F. The best way to avoid this issue is to read and write bytes, not characters. Makes you code a lot easier too, you don't have to do all the string conversions.

    - Variable Array identifiers First, you can't find a variable from its name. The name is used in your code, it is not available at runtime. Second, don't use System.Array as a Type. You should use Form() or String() or whatever the array is of. If you need to store three arrays of Forms and refer to them by name then you would have to do... Code Snippet Public Class Form1 Public AllTempTabs(9) As Form Public AllListTabs(9) As Form Public AllEventTabs(9) As Form Public AllTabs As New Dictionary( Of String , Form()) Sub New () InitializeComponent() ' Store the Form arrays in the dictionary, ' the string acts as a key to retreive a ' specific array. AllTabs.Add( "AllTempTabs" , AllTempTabs) AllTabs.Add( "AllListTabs" , AllListTabs) AllTabs.Add( "AllEventTabs" , AllEventTabs) End Sub Sub MakeNewTab( ByVal tabName As String ) Dim currentArray() As Form = AllTabs( "All" & tabName & "Tabs" ) End Sub End Class Tag: Visual Basic Express Edition password string question Visual Studio Express Editions

    - hold down key Well one way would be to use the ModifiedKeys that is a static member of the Form class: if ( ( Form.ModifierKeys & Keys.Control ) == Keys.Control ) { } so you're code would be: if ( e.Button == MouseButtons.Right && ( ( Form1.ModifierKeys & Keys.Control ) == Keys.Control ) ) { } another way would be to turn on KeyPreview on your form, and inside the Form's KeyDown event, set a flag to indicate Control (Ctrl) is held down, then on KeyUp event clear the flag.

    - Why To Not Use Threading.Sleep in Your Application I just wanted to say thank you reneec I really appreciate the explanation, i would really like to see more info on other points as well. So many times i see - don't do this or don't do that. And the answer although really long, does not quite explain why. And that may also be because the answer is over out heads. This thread is a perfect example for many: it shows you what you shouldn't do and now here is how you should do it. And why not to do it is explained very well. And even better it has "Real World" examples. Wonderful Many times i feel like the knowledge that you more experienced programmers have is just sitting idle and teased by throwing simple code bits at us. Which many times that's what were askin for. And even though it gets you to the next point, many don't even know how or why it works. It just does. And i see the frustration all the more experienced have when us beginners just don't get it. Even though the answer you gave is the right one, we are still looking for the answer even though you gave it because we just don't understand how to put it together. Thanks again, hope to see more.

    - how to convert Date to Integer DateTime.Subtract() subtracts two dates. So does Date.Subtract(). It produces a TimeSpan instance, use any of its properties to measure the difference. The Ticks property is the most accurate but you'll probably want to use something like TotalSeconds or TotalDays. The VB.NET DateDiff() function produces a Long value (not Integer). For example: Dim diff As Integer = CInt(DateDiff(DateInterval.Second, d1, d2)) Tag: Visual Basic Express Edition password string question Visual Studio Express Editions

    - How could I read 300 characters from a text file? This is quiet cool, i asked the question but before any help was given to me I fiqured out a solution for it! To read a certain length of characters in any file I could do the following: Code Snippet ' This creats an array from the specified file, in this case "C:\Text.Txt". Dim buffering() = My.Computer.FileSystem.ReadAllText("C:\Text.Txt").ToArray Dim i as integer While i <= 250 value = value & buffering(i).ToString i += 1 End while ' The variable `value` would contain the first 250 characters ' of the file which in this case is "C:\Text.Txt". Then every time the next 250 or any other integer value of characters are required you could add the above While loop statment to obtain the next block of code. (The block of code could vary in this example it was 250, but it could be any thing you like, at every while loop statment) But insure that you don't change the value of ' i '.

    - web browser stuff.. I will address questions 2 and 3 for you: To show the page title in the form’s title bar: Hook up a Document_Completed event handler for the webBrowser and put this code into it: this .Text = webBrowser1.DocumentTitle; (To create a Document_Completed event handler, go to the Design view and select the webBrowser control. Then in the properties window, click on the lightning bolt icon which should show a list of events for the browser. Find the one labeled ‘DocumentCompleted’ and double-click it. This should take you back to code view and the event handler will be added. Put the code listed above into the handler.) To prevent IE from opening a new window you need to intercept the NewWindow event. I presume you want to open a new window with another instance of your webBrowser form. And you want to be able to do the same by right-clicking a link. Hook up a NewWindow event handler using the same technique above and add the following code: Form1 f1 = new Form1 (lastUrl); f1.Show(); e.Cancel = true ; This creates a new Form1 (I am assuming that this is the form that your browser control is on), passes a string called ‘lastUrl’ (more on this later). Launches the form and cancels the event. So, whenever the browser needs to create a new window, this routine will make a new browser for you and stop the event from launching a window in IE. Now, we need to make Form1 display the web page that we just passed to it. Make the constructor of Form1 look like this: public Form1( string url) { InitializeComponent(); webBrowser1.StatusTextChanged += new EventHandler (webBrowser1_StatusTextChanged); webBrowser1.Navigate(url); } This makes Form1 receive a string url and uses it to navigate the webBrowser whenever it is created. The webBrowser1.StatusTextChanged … line hooks up an event handler that is not in the list of handlers that you can choose from in the properties window. So you will have to add this event handler like this: string lastUrl; void webBrowser1_StatusTextChanged( object sender, EventArgs e) { string s0 = webBrowser1.StatusText; if (s0.Contains( "http" )) { lastUrl = s0; } toolStripStatusLabel1.Text = s0; //optional } The status text is what is displayed on the status strip at the bottom of most browsers. When you hover your mouse over a url, you will see this change. This bit of code looks for changes in this status and remembers the last bit of status that shows a url in the string variable ‘lastUrl’. This is the variable that we use to launch any new window either automatically or by right-clicking and selecting the ‘open in new window” option from the context menu. Optionally, you can add a toolstrip wit a toolStripStatusLabel to the bottom of your form and display the status like most browsers. Finally, one more bit of housekeeping. Assuming Form1 is the first form your program launches (it may not be since you have a splash screen), you will need to make the call to Form1 in the Program.cs file match your constructor. Change the Application.Run(new Form1()); line to: Application .Run( new Form1 ( "" )); This will provide the string to Form1 that the constructor is expecting. I hope this explanation was clear. Here is the complete listing of my Form1 which has a webBrowser, textbox, button, and toolStripStatusLabel: using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Text; using System.Windows.Forms; namespace WindowsApplication1 { public partial class Form1 : Form { public Form1( string url) { InitializeComponent(); webBrowser1.StatusTextChanged += new EventHandler (webBrowser1_StatusTextChanged); webBrowser1.Navigate(url); } string lastUrl; void webBrowser1_StatusTextChanged( object sender, EventArgs e) { string s0 = webBrowser1.StatusText; if (s0.Contains( "http" )) { lastUrl = s0; } toolStripStatusLabel1.Text = s0; } private void button1_Click( object sender, EventArgs e) { webBrowser1.Navigate(textBox1.Text); } private void webBrowser1_DocumentCompleted( object sender, WebBrowserDocumentCompletedEventArgs e) { this .Text = webBrowser1.DocumentTitle; } private void webBrowser1_NewWindow( object sender, CancelEventArgs e) { Form1 f1 = new Form1 (lastUrl); f1.Show(); e.Cancel = true ; } } } Tag: Visual Basic Express Edition password string question Visual Studio Express Editions

Re: Visual Basic Express Edition password string question

^Philipp^

just use some of the String-Namesprace's functions to check for the chars you want to be there (and how many times etc.): Contains, IndexOf, IndexOfAny, ToCharArray, Char/Substring, Split, Replace, etc. you can always find a way to work with these.
Personally - if I'd only want to make sure 1 of those specials chars is in the password - would be

If Password.IndexOfAny(new Char() {"*"c,"\"c,"."c}) > -1 Then 'Password is ok

Hi gibbo....

Your best bet is to use regular expressions... you can get some regular expression that validate strong passwords here

http://regexlib.com/Search.aspx k=password

Here's an example of how to use....

Code Snippet

Private Sub TextBox1_Validating(ByVal sender As System.Object, _

ByVal e As System.ComponentModel.CancelEventArgs) Handles TextBox1.Validating

If System.Text.RegularExpressions.Regex.IsMatch(Me.TextBox1.Text, _

"( =^.{8,30}$)( =.*\d)( =.*[a-z])( =.*[A-Z])( =.*[!@#$%^&*()_+}{"":;' />.<,]).*$") = True Then

'strong password

Else

'bad password

End If

End Sub

Edit: Sorry Philipp thats twice I've re-answered your posts, we must be posting at the same time.
