The best solution that I can think of, is to embed a link an image URL into your email, so that the image is downloaded from a website. The URL in the email would be something like
http:
So basically what you are doing is referencing the Image.aspx page with the parameters of i=logo (parameter i = logo) and a unique Id for the Email/Receipient.
What the Image.aspx does is record in a database that the Receipient has opened the email and downloaded the image, thus the email address is valid and been read. Then the page responds with an image.Steve Jowett

Hi all,
I want to know how to make service commands.
Thanks
|
|
|
|
|
1. Please don't cross post. It just confuses everyone.
2. Service Commands? Are you talking about making a windows service, or executing commands against a known service such as the FTP Service Commands?

There is a wealth of info out there on coding for SMS.
The first page of results on Google[^] has lots of good articles including one here on CodeProject. You just have to look for the right thing.

Experts,
I have some vb6 code that does exactly what i want it to do (yippee) however the program i am developing in is vb.net.
Now orignally i thought that most of the code would be fairly easy to convert however some of it isn't being liked.
This is the main code that i need help with
open App.path & "\files\high scores.txt" for input as #1
a=1
While not EOF(1)
Input #1, names(a), scores(a)
a=a+1
end while
close #1
vb.net doesn't like open app path and for input as #1as well as input #1 and close #1
If someone could help me that would be great.
Many thanks
Dan

Just an update here is what i have done in vb.net
dim objReader as new system.IO.StreamReader(FILE_NAME)
Do while not EOF(1)
list1.text = names(a) & objReader.readline()
a=a+1
loop
objReader.close
call highscores
For some reason when i try to run the code it doesn't like the dow while loop and says bad file name or number?
If anybody can help me that would be really cool

If you are using StreamReader then you can do this (taken straight from the documentation for StreamReader):
' Create an instance of StreamReader to read from a file.
Dim sr As StreamReader = New StreamReader("TestFile.txt")
Dim line As String
' Read and display the lines from the file until the end
' of the file is reached.
Do
line = sr.ReadLine()
Console.WriteLine(Line)
Loop Until line Is Nothing
sr.Close()
You don't need to worry about file numbers in VB.NET.

From what I can gather, basically what you are trying to do is to read a list of players and their high scores from a text file, and populate arrays named names and scores. In .Net you need to import System.IO and use a StreamReader to read from the file. An important consideration obviously, is the set up of the original text file. i.e - is it a comma delimted file ?, is each record on a new line ? etc. I threw this together, working on a few assumptions. 1. The text file is stored in the same folder as the application executable. 2. The text file consists of a new line for each player, and each player property is separated by a comma.
names = New List(Of String)
scores = New List(Of Integer)
Dim strFilename As String = Application.StartupPath & "\highscores.txt"
Dim srScores As New StreamReader(strFilename)
While Not srScores.EndOfStream
Dim strRead As String = srSave.ReadLine
ListBox1.Items.Add(strRead)
Dim strSplit() As String = Split(strRead, ",")
names.Add(strSplit(0))
scores.Add(strSplit(1))
End While
srScores.Close()
I also assumed names and scores were lists rather than arrays. You would obviously need to consider error handling as a major issue which I have completely ignored.
Hope this helps.

Cheers Zimvbcoder.
This is indeed very helpful 
However i have a few questions
names = New List(Of String) ' vb doesn't like the new list of string?
scores = New List(Of Integer)
Dim strFilename As String = Application.StartupPath & "\highscores.txt"
Dim srScores As New StreamReader(strFilename)
While Not srScores.EndOfStream
Dim strRead As String = srSave.ReadLine
ListBox1.Items.Add(strRead)
Dim strSplit() As String = Split(strRead, ",")
names.Add(strSplit(0)) ' doesnt like names.add?
scores.Add(strSplit(1))
End While
srScores.Close()
Also srSave isn't doing anything?
I am very grateful for you replying to my post.
Many thanks
Dan

For List(Of ) you need to import System.Collections.Generic.
As for srSave, I think you made a typo. It should be. Dim strRead As String = srScores.ReadLine()

|

Thanks the man from U.N.C.L.E
so are you saying that the following code would become
name = New list(of system.collection.generic) ?
This comes up saying do i want to change what i have written to
system.collection.IEnumerable
system.collection.IEnumerator
system.collection.Generic.list(ofT)
system.collection.queue
system.collection.generic.IList(ofT)
Many thanks
Dan

Other way round:
New System.Collections.Generic.List(Of String)
|
|
|
|
|
Sorry,
I just tried that, so the code is
names = New System.Collections.Generic.List(Of String)
but it comes up with an error as well as a blue squigly underneath saying it cannot be converted to '1 dimensional array of string??
I thank you for your patience
Dan

No worries.
Sounds like you have left the declaration of your variable as Dim names as string(). You need to change that to a List(Of as well. E.g.
Dim names = System.Collections.Generic.List(Of String)
names = New System.Collections.Generic.List(Of String)()
Or
If you have knowledge, let others light their candles at it.

I have decided to show the code that i am using from start to fininsh.
I am using 1 button called comtest
2 list boxes called listBox1 and ListBox2
2 textboxes called text1 and text2
Imports System.IO
Public Class Form1
Dim scores = New System.Collections.Generic.List(Of String)
Dim names = New System.Collections.Generic.List(Of String)
Dim test1(0 To 10) As String
Dim test2(0 To 10) As Integer
Dim userscore As Integer
Dim username As String
Dim a As Integer
Dim b As Integer
Dim i As Integer
Dim strFilename As String = ("High Scores.txt")
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Call highscore()
names = New System.Collections.Generic.List(Of String)
scores = New System.Collections.Generic.List(Of Integer)
Dim srScores As New IO.StreamReader(strFilename)
While Not srScores.EndOfStream
Dim strRead As String = srScores.ReadLine
ListBox1.Items.Add(strRead)
Dim strSplit() As String = Split(strRead, ",")
names.Add(strSplit(0))
scores.Add(strSplit(1))
End While
srScores.Close()
End Sub
Private Sub comtest_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles comtest.Click
username = Text1.Text
userscore = Val(Text2.Text)
For i = 1 To 10
a = scores(i)
If userscore >= a Then
test1(i) = username
test2(i) = userscore
For b = i + 1 To 10
test1(b) = names(b - 1)
test2(b) = scores(b - 1)
Next
Call newscore()
Exit Sub
End If
test1(i) = names(i)
test2(i) = scores(i)
Next
End Sub
Private Sub highscore()
For i = 1 To 10
ListBox1.Items.Add(names(i))
List2.Items.Add(scores(i))
Next
End Sub
Private Sub newscore() ' write
ListBox1.ClearSelected()
List2.ClearSelected()
For i = 1 To 10
ListBox1.Items.Add(test1(i))
List2.Items.Add(test2(i))
names(i) = test1(i)
scores(i) = test2(i)
Next
Dim objWriter As New System.IO.StreamWriter(highScoresFile)
For i = 1 To 10
objWriter.Write(names(i) & "," & scores(i))
Next
objWriter.Close()
End Sub
This is the VB6 version with the same properties
Dim scores(1 To 10) As Integer
Dim names(1 To 10) As String
Dim test1(1 To 10) As String
Dim test2(1 To 10) As Integer
Dim userscore As Integer
Dim username As String
Dim a As Integer
Dim b As Integer
Private Sub comtest_Click()
username = Text1.Text
userscore = Val(Text2.Text)
For i = 1 To 10
a = scores(i)
If userscore >= a Then
test1(i) = username
test2(i) = userscore
For b = i + 1 To 10
test1(b) = names(b - 1)
test2(b) = scores(b - 1)
Next
Call newscore
Exit Sub
End If
test1(i) = names(i)
test2(i) = scores(i)
Next
End Sub
Private Sub Form_Load()
Open App.Path & "\files\high scores.txt" For Input As #1
a = 1
While Not EOF(1)
Input #1, names(a), scores(a)
a = a + 1
Wend
Close #1
Call highscore
End Sub
Private Sub highscore()
For i = 1 To 10
List1.AddItem names(i)
List2.AddItem scores(i)
Next
End Sub
Private Sub newscore()
List1.Clear
List2.Clear
For i = 1 To 10
List1.AddItem test1(i)
List2.AddItem test2(i)
names(i) = test1(i)
scores(i) = test2(i)
Next
Open App.Path & "\files\high scores.txt" For Output As #1
For i = 1 To 10
Print #1, names(i) & "," & scores(i)
Next
Close #1
End Sub
I thought i had done coded the vb correctly with the help of zimvbcoder and the man from U.N.C.L.E howver have made a mistake somewhere. If someone can help me that would be very very very very helpful
Again thanks a million

Imports System.IO
Public Class Player
Implements IComparable
Private strName As String
Private intHighScore As Integer
Public Property Name() As String
Get
Return strName
End Get
Set(ByVal value As String)
strName = value
End Set
End Property
Public Property HighScore() As Integer
Get
Return intHighScore
End Get
Set(ByVal value As Integer)
intHighScore = value
End Set
End Property
Public Function CompareTo(ByVal obj As Object) As Integer Implements System.IComparable.CompareTo
Dim OtherPlayer As Player = CType(obj, Player)
Return Me.HighScore - OtherPlayer.HighScore
End Function
Shared Function GetAllPlayers(ByVal FileName As String) As List(Of Player)
Dim lstPlayers As New List(Of Player)
Dim strFilename As String = FileName
Using srScores As New StreamReader(strFilename)
While Not srScores.EndOfStream
Dim newPlayer As New Player
Dim strRead As String = srScores.ReadLine
Dim strPlayerProperties() As String = Split(strRead, ",")
newPlayer.Name = strPlayerProperties(0)
newPlayer.HighScore = strPlayerProperties(1)
lstPlayers.Add(newPlayer)
End While
End Using
Return lstPlayers
End Function
End Class
Then you can declare a list(Of Player) in your main form and populate it like this :
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Try
lstPlayers = Player.GetAllPlayers(My.Settings.HighScoresFile)
lstPlayers.Sort()
For i As Integer = 0 To lstPlayers.Count - 1
ListBox1.Items.Add(lstPlayers(i).Name & ", " & lstPlayers(i).HighScore)
Next
Catch ex As System.IO.IOException
MsgBox("There was an error retrieving High Scores.")
End Try
End Sub
This is very simple but a good way to start thinking in a more structured way.

This LOOKS pretty awsome
I have one error and i don't actually know why.
lstPlayers = Player.GetAllPlayers(My.Settings.HighScoresFile)
VB doesn't like .High Scores File.
This is probably something stupid whch i've done but i can't work out why that doesn't like it?
Thanks again
Dan

Hi there. Sorry it is my fault, I forgot to mention that where ever possible it is not a good idea to hardcode things like Filenames, Connectionstrings, etc into your app. The best way to do this is to use your Application.Settings file which is automatically generated for you by VS. To access the settings file, right click on your project in Solution Explorer, select properties and a form should open up with various tabs to set up options for your app. Select Settings tab and there you can store application specific settings such as file names and connection strings. To set up HighScoresFile, type the name HighScoresFile under name, under type select string, under scope select application, and under value put the full address of the file. To access any of your settings then from your app you call My.Settings.'insert setting name here'. When considering where to put the file, you need to take into account where you will deploy the application and where the High Scores file will actually be kept when the app has been deployed on other machines. Hope this helps.

when running application when program hits this code I get this error.
<code> For y As Integer = 0 To frmtodayscafe.count
For x As Integer = 2 To 12
writeline1(x) = filename(y) + vbTab + frmtodayscafe.totalitemquantity(y) + vbTab + FormatCurrency(filename1(y)) + vbTab + vbTab + FormatCurrency(frmtodayscafe.cost(y))
Next
Next</code>
cheeseburger is assign to filename(y) which is declared as a string array
filename1(y) is a numeric value cost of the cheeseburger. writeline1(x) is also a string array.
by changing the code to the following:
writeline(x) = filename(y) + vbTab + format(frmtodayscafe.totalitemquantity(y)) + vbTab + FormatCurrency(filename1(y)) + vbTab + vbTab + FormatCurrency(frmtodayscafe.cost(y))

Where come from the value "cheeseburger"? Which variable hold that value? Are you trying to do a "FormatCurrency" on that value?
|
|
|
|
|
cheeseburger is a string loaded from a file .... I am trying to write the string to a concatenated string to include qty, pricing, and total pricing.
it should say on the string
cheeseburger 1 $3.00 $3.00
|
|
|
|
|
What is the type of writeline1(x)? Is it a string or double?
