Re: Does your code show the message box when you use "James007" as an input?

Re: See first: [URL="http://www.daniweb.com/forums/announcement58-2.html"]We only give homework help to those who show effort[/URL] announcement. I'll give you something to get started with. VB.NET stores controls in controls collections, so you can't have a control array (of checkboxes) like in VB6. Here's an example, how to loop a control collection and check … | |

Re: A bullet-proof method is [CODE=VB.NET]WebBrowser1.AllowNavigation = False[/CODE] but that does prevent [B]all[/B] navigation. That's probably what you don't want. You could trap NewWindow event (like you did) [CODE=VB.NET]Private Sub WebBrowser1_NewWindow(ByVal sender As Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles WebBrowser1.NewWindow ' Prevent opening a new windows e.Cancel = True End Sub[/CODE]and … | |

Re: VB.NET stores controls, like text boxes, to a control collection. See [URL="http://www.daniweb.com/forums/thread192517.html"]this[/URL] DaniWeb's thread, how to loop through the control collection, recognize text boxes and finally, how to use control's properties. | |
Re: Was it SendEmailMessage and/or SendFakeEmailMessage that throws the error? Anyway, change [CODE=VB.NET]SmtpMail.Send(mailmsg)[/CODE] to [CODE=VB.NET]Try SmtpMail.Send(mailmsg) Catch ex As Exception MessageBox.Show(ex.Message, "Error", MessageBoxButtons.OK, MessageBoxIcon.Error) Debug.Print(ex.Message) End Try [/CODE]and then please post the error message you receive.

Re: Use ToShortDateString of the DateTime class. Here's an example [CODE=VB.NET]Dim SQLDateTime As Date Dim OnlyDate As String ' Debug, get this value from SQL Server. Notice: This is my locale date format SQLDateTime = CDate("15.5.2009 15:53:00") OnlyDate = SQLDateTime.ToShortDateString MessageBox.Show(OnlyDate, "Only Date", MessageBoxButtons.OK, MessageBoxIcon.Information)[/CODE] | |
Re: The only problem is to validate user input as a valid file name.

Re: The timer control can't go "backwards". You'll have to "count" the elapsed time "forward" [CODE=VB.NET]Private Const MAX_MINUTES As Integer = 60 ' 1 hour, change this value (has to be > 0) Private CurrentMinute As Integer ' Track minutes Private CurrentSecond As Integer ' Track seconds Private Sub Form1_Load(ByVal sender … | |

Re: [QUOTE]I would like to come up with a number generator that takes the Total number (for this example I'll say 20), divides it by 2, and does alternating additions so the end result will generate a list like this: 1, 11, 2, 12, 3, 13, 4, 14, 5, 15, 6, … | |
Re: [QUOTE]though maybe I could just declare them globally once[/QUOTE]Yes, you can do that [CODE=VB.NET]Public Class Form1 Dim number1 As Double Dim number2 As Double Dim total As Double . . .

Re: If I understood your question right I don't see any reason why that can't be done. I won't give you any code. It's better that you learn first the basics of d&d and try to do it yourself. I quickly googled three articles which get you started. They're for VB.2003 … | |

Re: IO.WatcherChangeTypes.Changed is raised when the file's [B]or[/B] the folder's size, attributes, last accessed etc. are changed. First, filter [ICODE]FileSystemWatcher1.NotifyFilter = NotifyFilters.LastWrite[/ICODE]This should assure that the event is raised only when the file is updated.

Re: .NET has a FileSystemWatcher control which monitors changes in a given directory and notifies if there are changes made. See MSDN documentation of [URL="http://msdn.microsoft.com/en-us/library/system.io.filesystemwatcher(VS.80).aspx"]FileSystemWatcher Class[/URL]. | |
Re: [QUOTE]I am obviously missing something[/QUOTE]Yes, you are. You take a [ICODE]Dim RowValue As String = Mid(Line, 96, 9)[/ICODE] which would be a nine character long string.

Re: Declare your array to class level scope and initialize array in form's load event, like this [CODE=VB.NET]Public Class Form1 Private s() As Integer Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load ' Initialize array s(0) = 0 s(1) = 0 s(2) = 0 s(3) = 0 … | |
Re: Actually your code does the opposite thing. It adds to third list box items from list box A that do exist in list box B. Otherwise, there's nothing wrong with your code. Here's your code (list boxes renamed) [CODE=VB.NET] ListBox1.Items.Add("first@acme.com") ListBox1.Items.Add("second@acme.com") ListBox2.Items.Add("second@acme.com") ListBox2.Items.Add("third@acme.com") For k As Integer = ListBox1.Items.Count - … | |

Re: a) No. But if you can separate the "sensitive" part of the code to a different project, you could compile it as a DLL and use obfuscator. Even that doesn't provide a total, 100% protection b) I suggest using version controlling with branch/merge. MS has its SourceSafe but there are … | |

Re: Start recursing folders and files from current user's Start Menu[CODE=VB.NET] Dim StartMenu As String StartMenu = My.Computer.FileSystem.SpecialDirectories.Programs[/CODE]I don't have VB2003 so I didn't check if it works with that. | |
Re: [QUOTE]my code only opens the last part of the file it read[/QUOTE] Actually only the last line. [ICODE]RichTextBox.Text = fileString[/ICODE] replaces the content of the richtextbox each time you read the next line. You should append lines so the previous content is not lost [CODE=VB.NET]RichTextBox.AppendText(fileString)[/CODE] You could also check [ICODE]My.Computer.FileSystem.ReadAllText[/ICODE] … | |
Re: [ICODE]Debug.Print(NfcCommOpen(Me.Handle), "1"))[/ICODE] passes a handle to form. The prototype is short NfcCommOpen(HANDLE *hCom, char *com_port) and parameters: - hCom-series handle - com_port, file name of series port IMO you should pass a "hCom-series handle" as the first parameter, not a handle to form. I guess the function tries to open … | |
Re: That's an error image i.e. some image can't be found. At least [ICODE]mybutton.Image = Image.FromFile("tripleword.jpg")[/ICODE] may not look for the image from the place you were thinking of. Also, you can't assign to picture box in itself, use Image property. | |
Re: [QUOTE]why isnt there a mouseclick event in the webbrowser method listbox?[/QUOTE]Because the mouse click is sent to the web page shown in the control.

Re: Declare your variable in the class itself. It will be a class-level variable and every procedure in the class can access it unless you "hide" it with a procedure level variable.
