Thanks for reply dear,
The problem is that When I build the Ruler and add it to a form then I set the rulers autowidth property to True and run the Application it shows me the following error.
System.InvalidOperationException was unhandled

Hi
I have DatePicker and the Maxdate is set to today:
I am struggling with the MinDate.
I need to set the Mindate to the 1st of 3 Months back(Keep in mind that the current month will be 3rd Month).
Ex.1
For instance if we work it out as today the MinDate has to be: 01 January 2010
Ex.2
if today is the 16th of April 2010 the min date has to be: 01 Feb 2010
I hope someone can help me with this as I am really struggling with this calculation
Thank you in advanced

I think this is what you want
minDate = DateAdd(DateInterval.Month, -2, Today)
minDate = DateAdd(DateInterval.Day, (Today.Day - 1) * -1, Today)

Thank you Steven, but if I work it from todays day it should be 01/01/2010 but the result your code gives is 3/1/2010.
I do appreciate your effort in helping.I'll try to work with this code and try to change it.
Thank you so much

Thank you so much Steven
I have changed the second line of code and replaced today with mindate and its working perfect.
Im just wondering now what would happen if this month has 31 days and 3 months back has only 30.

Either reset your system clock to an appropriate date (not forgetting Feburary only has 28 days or 29 on Leap years).
Define a DateTime varable and use the DateSerial function to populate it with your test date, then use the testing dateTime variable instead of the current system date, to test your code.

I have a webpage with text boxes, Radio Buttons and a Button.
User is to fill in the boxes and select a radio button, fill in the message box and then press send.
I want to send to an email address dependant on the radio button choice, and I cannot get it to work.
Here is the code
Public Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim strName As String
Dim strAddress As String
Dim strMessage As String
Dim strType As String
Dim strSendTo As String
Dim strSendFrom As String = "WebAddress"
Dim CompleteMessage As String
strName = ContactName.Text()
strAddress = ContactAddress.Text()
strMessage = TextBox1.Text()
strType = RadioButtonList1.SelectedValue
Select Case strType
Case "sales"
strSendTo = "silverfox@live.co.uk"
Case "contractors"
strSendTo = "colin@fosbern.co.uk"
Case "general"
strSendTo = "pat@fosbern.co.uk"
Case Else
strSendTo = "enquiries@fosbern.co.uk"
End Select
CompleteMessage = "Message From Website " & vbNewLine & strSendFrom & vbNewLine & strSendTo _
& vbNewLine & vbNewLine & strType & vbNewLine & strMessage
Sendmsg(, strSendTo, CompleteMessage)
End Sub
Sendmsg is called, here, so far is what I have,
Public Sub Sendmsg(Optional ByVal msgfrom As String = "", Optional ByVal msgto As String = "", _
Optional ByVal msgmessage As String = "")
Dim SendMessage As New MailMessage
Try
With SendMessage
.To (msgto)
.From (msgFrom)
.Body (msgmessage)
.send
End With
Catch ex As Exception
End Try
End Sub
But it is starting to fall apart.
Arrghhh! I have been at this for ages.
I have the following imports
Imports System
Imports System.Net
Imports System.Net.Mail
Imports System.Net.Mail.MailMessage
It is having problems with assigning values to the to and from variables.

Something like this?
Public Sub SendMessage(ByVal sTOList As String, ByVal sSubject As String, _
ByVal sBody As String, ByVal sCallingRoutine As String)
Dim oMsg As New MailMessage
With oMsg
.From = New MailAddress("xxxxxx@xxxxx.com")
For Each sAddr As String In Split(sTOList, ";")
.To.Add(sAddr)
Next
.Priority = MailPriority.Normal
.Subject = sSubject
.Body = sBody
End With
Try
Dim oSMTP As New SmtpClient
oSMTP.Host = "xxxxxxxx"
oSMTP.Send(oMsg)
Catch ex As Exception
MessageBox.Show("Could not send the status email message." & ControlChars.CrLf & _ ex.ToString, sCallingRoutine, MessageBoxButtons.OK, MessageBoxIcon.Stop)
End Try
End Sub

Thanks, I was too tired to try again last night, but I shall have a crack with this method tonight.

Problem Solved
All it took was to go and make a cup of tea!
Code so far...
Public Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim strName As String
Dim strAddress As String
Dim strMessage As String
Dim strType As String
Dim strSendTo As String
Dim strSendFrom As String = "WebSite"
Dim CompleteMessage As String
strName = ContactName.Text()
strAddress = ContactAddress.Text()
strMessage = TextBox1.Text()
strType = RadioButtonList1.SelectedValue
Select Case strType
Case "sales"
strSendTo = "sales@ACME.co.uk"
Case "contractors"
strSendTo = "colin@ACME.co.uk"
Case "general"
strSendTo = "pat@ACME.co.uk"
Case Else
strSendTo = "enquiries@ACME.co.uk"
End Select
CompleteMessage = "Message From Website " "
I want the complete message to show the name of the sender, their address on the next line and the type on the third.
Then a two line gap for the message itself.
So, How do I add a Carriage Return to the message?
I have tried googling, but found unsatisfactory answers.

CompleteMessage = "The person's name" & ControlChars.CrLf & _

My teacher want's me to design a program that does this. "Design a program that has five buttons, one for each grade. Each time you press a button it increments that grade by one. At the same time it updates a label that displays the current percent of students that passed the exam (grade higher than F)." This is what I have so far...
Public Class Form1
Private Sub btnA_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnA.Click
Static intA As Integer = 0
intA = intA + 1
lblGradea.Text = intA
End Sub
Private Sub btnB_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnB.Click
Static intB As Integer = 0
intB = intB + 1
lblGradeb.Text = intB
End Sub
Private Sub btnC_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnC.Click
Static intC As Integer = 0
intC = intC + 1
lblGradec.Text = intC
End Sub
Private Sub btnD_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnD.Click
Static intD As Integer = 0
intD = intD + 1
lblGraded.Text = intD
End Sub
Private Sub btnF_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnF.Click
Static intF As Integer = 0
intF = intF + 1
lblGradef.Text = intF
End Sub
End Class
I need help on that part that displays what percentage of students are passing. I assume you have to add together the toal number of grades and then divide by the total number above F and display that in a label. But I cant seem to figure that out...Thanks

My interpretation of the problem is that every time you press a button, the number of students with that particular grade is incremented.
That means that your result must be sum(intA to intE)/ sum(intA to intF).
|
|
|
|

I don't normally do student's homework, but seeing as you have attempted to solve the problem here is some pointers...
Remove the lines that declare the STATIC integer and make the PRIVATE member variables e.g.
Public Class Form1
Private intA As Integer
Private intB as Integer
Private intC as Integer
Private intD as Integer
Private intF as Integer
In the Form_Load Event handler, initiate the starting values e.g.
intA = 0
intB = 0
Now all you need is a Function to return the averages.

  Thank you both for steering me in the right direction. Not sure if its the most effcient way of making the program but it does what it's supposed to. Here is the final code...
'Adam Wike

The above should not be repeated in every button click event. Consider making in a sub-routine for example :
Private Sub CalcIntE()
intE = ((intA + intB + intC + intD) / (intA + intB + intC + intD + intF)) * 100
lblPassing.Text = Math.Round(intE, 2) & "%"
End Sub
Then replace the necessary code in each button click event with CalcIntE
for example
Private Sub btnA_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BtnA.Click
intA = intA + 1
lblGradea.Text = intA
CalcIntE
End Sub

Your right, that is a lot less confusing and makes the program look less cluttered. Thanks!

Not only that, but more importantly, it is more maintainable.

Use the HTTP classes to navigate tot he desired page and obtain its contents. then use the TextWriter to dump it to a filestream.
That is one method.
